Objective: Determining the microbiological quality of both packaged and freshly made fruit and milk juices. Method: The spread-plate approach was employed to isolate and count the bacteria. 90 ml of sterile peptone water were blended with 10 ml of well-mixed, packed, and freshly made fruit juices. The samples were sequentially diluted (101 - 105) in accordance with the Indian Manual of Food Microbiological Testing Methods. Results: From eight samples of imported packaged fruit and milk juice, the average of total coliform, staphylococci, and viable bacterial counts were zero, 1.39 × 102, and 2 × 102 CFU/ml, respectively. In contrast, from three samples of locally produced fruit and milk juice, the average of total coliform, staphylococci, and viable bacterial counts were zero, 5.83 × 102, and 2.73 × 103 CFU/ml, respectively. Four samples of handmade prepared fruit and milk juices had a mean of total coliform, staphylococci, and viable bacterial count of 1.441 × 104, 4.1 × 103, and 2.35 × 105 CFU/ml, respectively. Conclusion: 33.3% of the results from microbiological analysis of freshly made fruit and milk juices met the permissible range of the Revised Microbiological Standards for Fruit and Vegetables and Their Products, which were published in 2018 and as well as the Hong Kong Center for Food Safety, whereas 66.7% of the microbiological analyses of freshly prepared fruit and milk juices were above the permissible reference range of GSO standard 2000. 12.5% of the investigated imported and packed fruits and milk juices had one failed test (TSC), which was above the acceptable limit, 87.5% of the tested samples of fruit and milk juices fulfilled the necessary standards of TCC, TVBC, and TSC. 100% of the tested locally manufactured fruit and milk juices complied with TSC, TCC, and TVBC requirements. All investigations showed that freshly made fruit and milk juices were heavily contaminated (Total viable bacterial count, total coliform count, and total staphylococcus count). .展开更多

The present study sought to investigate the prevalence and associated factors of viral hepatitis C (VHC) among the Burundian population during a screening campaign. A total of 629 participants took part in the study, and the prevalence of viral hepatitis C was (8.11%). The associated factors identified as statistically associated were medical and surgical history (P = 0.02) and ear and nose piercing (P = 0.01). 51% of the infected persons were females. The mean age for viral hepatitis C carriage was 46.13 ± 14.3 years and 10.40% of viral hepatitis C carriers were over 50 years old. We found a high viral hepatitis C prevalence in married (9.55%) and divorced (9.38%) participants. The majority of our participants were farmers (60.25%) with a prevalence of viral hepatitis C (7.92%) while 11.54% of the infected participants were not educated. In conclusion, the current study shows a high prevalence of Viral Hepatitis C infection in Burundi. Infection was more likely to occur in older, married, farmer, and illiterates. Unsafe medical and surgical interventions with traditional practitioners were significant risk factors for contracting VHC infection.展开更多

Methodology: This was a prospective descriptive cross-sectional study carried out in the Radiology Department of Donka National Hospital over a period of ten (10) months. It involved 78 women who came to the department for hysterosalpingography and/or pelvic ultrasound examinations, as part of the exploration of infertility. Data collection involved the use of pre-established survey forms to gather information on the parameters studied. Sociodemographic parameters, ultrasound and hysterosalpingography results were studied. A correlation was made between age at marriage and infertility to determine whether early marriage has an impact on primary infertility, with a statically significant result for p value greater than 0.05. Results: The mean age of our patients was 33.7 ± 5.6 years, with extremes of 18 and 35 years. The 18-35 age group was the most represented, with a frequency of 80.7%. The 34% of our patients were married before the age of 18, with a marriage duration ranging from 6 months to 15 years. The indication for investigations was dominated by secondary infertility, with a frequency of 65%, followed by primary infertility (35%). All our women underwent ultrasound-hysterosalpingography, i.e. 100%, in search of the cause of infertility. Ultrasound was pathological in 35.8%. The most common ultrasound lesions were myomas and ovarian dystrophies, with 12.8% each. However, hysterosalpingography was pathological in 35%. Tubal obstructions affected almost a third of our women (29.5%), followed by phimosis and tubo-peritoneal adhesions. Conclusion: Diagnostic evaluation of infertility requires a multidisciplinary approach, including collaboration between infertility gynecologists, radiologists and other infertility specialists. Medical imaging remains indispensable in the evaluation of female infertility.展开更多

On the other hand, nurses who personally embrace physical activity are more likely to encourage their patients to improve their health through physical activity or diet. As a result, promoting an active and healthy lifestyle among student nurses is important because this has a crucial role in their subsequently encouraging healthy lifestyles among their patients. The aims of this study were to determine the physical activity levels and health-promoting lifestyles among student nurses in Malaysia, and to investigate whether there was a correlation between the physical activity levels of student nurses and their lifestyle habits. Further investigation was also carried out to correlate lifestyle habits with physical activity during weekdays and at the weekends. This study involved 189 student nurses who were pursuing Diplomas and Bachelor Degrees in local government universities. The Yamax Digi-Walker pedometer was used to measure physical activity, while the Health-Promoting Lifestyle Profile (HPLP) II questionnaire was used to assess the health-pro- moting lifestyles of the participants. The HPLP II consisted of six sub-scales which included health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, and stress management. According to the results on physical activity, the student nurses had a mean of 8275.97 ± 2210.174 steps per day and were thus categorised as somewhat active. Additionally, the student nurses were found to be more active during weekends (M = 8389.75, SD = 2689.12) as compared to weekdays (M = 8230.46, SD = 2353.97). According to previous studies, both step counts are classified in the “somewhat active” category. Overall, the results for HPLP II showed that student nurses students in Malaysia had a positive health-promoting lifestyle with a score of 2.58 ± 0.34 on a 4-point Likert scale. The highest score was reported in spiritual growth, with a score of 2.92 ± 0.43. Meanwhile, physical activity was observed to be the lowest, with a score of 1.74 ± 0.39. The results found no correlation between physical activity and overall health-promoting lifestyle among student nurses in Malaysia (r = 0.06, n = 189, p < 0.37). However, there was a significant relationship between physical activity (measured by the pedometer) and physical activity habit (measured through the questionnaire) among the student nurses (r = 0.24, n = 189, p < 0.01). According to the findings, when the participants indicated in the questionnaire that they were active physically, the pedometer readings also showed a corresponding similarity in terms of their daily physical activities.展开更多

Aberrant MAPK signaling plays a pivotal role in carcinogenesis, which leads to development and progression of human cancer. Dual-specificity phosphatase 6(DUSP6), a member of the MAPK phosphatase family, interacts with specifically targeted extracellular signal-regulated kinase 1/2 via negative feedback regulation in the MAPK pathway of mammalian cells. This phosphatase functions in a dual manner, pro-oncogenic or tumor-suppressive, depending on the type of cancer. To date, the tumor-suppressive role of DUSP6 has been demonstrated in pancreatic cancer, non-small cell lung cancer, esophageal squamous cell and nasopharyngeal carcinoma, and ovarian cancer. Its pro-oncogenic role has been observed in human glioblastoma, thyroid carcinoma, breast cancer, and acute myeloid carcinoma. Both roles of DUSP6 have been documented in malignant melanoma depending on the histological subtype of the cancer. Loss-or gain-of-function effects of DUSP6 in these cancers highlights the significance of this phosphatase in carcinogenesis. Development of methods that use the DUSP6 gene as a therapeutic target for cancer treatment or as a prognostic factor for diagnosis and evaluation of cancer treatment outcome has great potential. This review focuses on molecular characteristics of the DUSP6 gene and its role in cancers in the purview of development, progression, and cancer treatment outcome.展开更多

文摘Objective:To investigate the interrelationship between cardiovascular health awareness,risk perception,behavioural intention,and INTERHEART risk stratification in a middle-aged adult population in Malaysia.Methods:A cross-sectional survey with convenience sampling was conducted during November 2022 and January 2023.Participants completed validated questionnaires assessing cardiovascular health awareness,risk perception of cardiovascular diseases,behavioural intention towards adopting healthy habits,and INTERHEART risk stratification score(IHRS)based on established risk factors.A total of 602 respondents were included in the final analysis.Data were analysed with independent t-test/one-way ANOVA or Mann-Whitney/Kruskal-Wallis to test the differences,Pearson correlation or linear regression test to analyze the association of independent and dependent variables.Results:There was a significant positive correlation between medical knowledge related to cardiovascular disease(CVD)and knowledge related to CVD risk prevention,risk perception,behavioural intention and IHRS(P<0.05,Pearson correlation).Notably,individuals with higher IHRS tended to have lower knowledge related to CVD and CVD risk prevention,risk perception,and behavioural intention.Males,laborers,active/former smokers,individuals with lower household income and educational levels,those involved in occupations not related to the healthcare sector,and those who did not receive the CVD health brochure or are unaware of health self-assessment tools are likely to have lower levels of knowledge,risk perception,and poorer behavioural intention regarding cardiovascular health(P<0.05,one-way ANOVA).While educational level,smoking status,awareness about CVD poster,self-assessment tools were repeatedly significantly associated with knowledge related to CVD and CVD risk prevention,risk perception,behavioral intention and/or IHRS(P<0.05,linear regression).Conclusions:These findings underscore the importance of promoting cardiovascular health awareness and risk perception among middle-aged adults to foster positive BI and reduce CVD risk.Tailored interventions targeting specific risk factors identified by INTERHEART may enhance risk stratification accuracy and facilitate targeted preventive strategies.

文摘Objective:To determine the distribution,phenotypic and genetic background of extended spectrumβ-lactamases(ESBL)-producing Klebsiella(K.)pneumoniae clinical isolates associated with K1 and K2 serotypes in two selected hospitals in Malaysia.Methods:A total of 192 K.pneumoniae isolates were collected and subjected to antibiotic susceptibility,hypermucoviscosity test and multiplex PCR to detect the presence of K1-and K2-serotype associated genes.Multilocus sequence typing(MLST)was performed on ESBL-producing K.pneumoniae isolates presented with K1 and K2 serotypes,followed by phylogenetic analysis.Results:A total of 87 out of 192(45.3%)of the K.pneumoniae isolates collected were ESBL producers.However,only 8.3%(16/192)and 10.9%(21/192)of the total isolates were detected to carry K1-and K2-serotype associated genes,respectively.Statistical analysis showed that K1 and K2 capsular serotypes were not significantly associated with ESBL phenotype(P=0.196).However,they were significantly associated with hypervirulent,as demonstrated by the positive string test(P<0.001).MLST analysis revealed that ST23 as the predominant sequence type(ST)in the K1 serotype,while the ST in the K2 serotype is more diverse.Conclusions:Although the occurrence of ESBL-producing isolates among the hypervirulent strains was low,their coexistence warrants the need for continuous surveillance.MLST showed that these isolates were genetically heterogeneous.
文摘BACKGROUND Time-restricted eating(TRE)is a dietary approach that limits eating to a set number of hours per day.Human studies on the effects of TRE intervention on cardiometabolic health have been contradictory.Heterogeneity in subjects and TRE interventions have led to inconsistency in results.Furthermore,the impact of the duration of eating/fasting in the TRE approach has yet to be fully explored.AIM To analyze the existing literature on the effects of TRE with different eating durations on anthropometrics and cardiometabolic health markers in adults with excessive weight and obesity-related metabolic diseases.METHODS We reviewed a series of prominent scientific databases,including Medline,Scopus,Web of Science,Academic Search Complete,and Cochrane Library articles to identify published clinical trials on daily TRE in adults with excessive weight and obesity-related metabolic diseases.Randomized controlled trials were assessed for methodological rigor and risk of bias using version 2 of the Cochrane risk-of-bias tool for randomized trials(RoB-2).Outcomes of interest include body weight,waist circumference,fat mass,lean body mass,fasting glucose,insulin,HbA1c,homeostasis model assessment for insulin resistance(HOMA-IR),lipid profiles,C-reactive protein,blood pressure,and heart rate.RESULTS Fifteen studies were included in our systematic review.TRE significantly reduces body weight,waist circumference,fat mass,lean body mass,blood glucose,insulin,and triglyceride.However,no significant changes were observed in HbA1c,HOMA-IR,total cholesterol,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,heart rate,systolic and diastolic blood pressure.Furthermore,subgroup analyses based on the duration of the eating window revealed significant variation in the effects of TRE intervention depending on the length of the eating window.CONCLUSION TRE is a promising chrononutrition-based dietary approach for improving anthropometric and cardiometabolic health.However,further clinical trials are needed to determine the optimal eating duration in TRE intervention for cardiovascular disease prevention.
文摘This review attempts to delineate the effects and roles of fermented foods on allergic responses(AR),specifically from milk,plant,and meat sources.Evidence for AR alleviation and aggravation were noted for many different fermented food groups.Positive outcomes on AR through fermented foods could be linked to microbial hydrolysis of food allergens,improvement in gut microbiota robustness,and modulation of the immune system that promotes a balance between T helper 1(Th1)and Th2 cells.Studies on plant-based,non-protein rich fermented foods tend to show more favourable results compared to those on meat-based or protein-rich group.The usage of specific and known starter cultures are helpful in alleviating AR,as in the case for many yogurt,Kefir or Dahi products.Sufficient fermentation time was also deemed important,exemplified in studies that showed inefficient AR reduction through consumption of fresh cheese.However,formation of new allergens through fermentation of certain meat-based foods,or by using specific fermenting microbes(e.g.Penicillium sp.),is possible.Thus,combination of starter cultures and food substrates must be considered in preventing or eliminating AR from intake of these foods.This review may aid consumers to make informed decision during the consumption of fermented food.

文摘BACKGROUND Timing of passaging,passage number,passaging approaches and methods for cell identification are critical factors influencing the quality of neural stem cells(NSCs)culture.How to effectively culture and identify NSCs is a continuous interest in NSCs study while these factors are comprehensively considered.AIM To establish a simplified and efficient method for culture and identification of neonatal rat brain-derived NSCs.METHODS First,curved tip operating scissors were used to dissect brain tissues from new born rats(2 to 3 d)and the brain tissues were cut into approximately 1 mm^(3)sections.Filter the single cell suspension through a nylon mesh(200-mesh)and culture the sections in suspensions.Passaging was conducted with TrypLTM Express combined with mechanical tapping and pipetting techniques.Second,identify the 5th generation of passaged NSCs as well as the revived NSCs from cryopreservation.BrdU incorporation method was used to detect self-renew and proliferation capabilities of cells.Different NSCs specific antibodies(anti-nestin,NF200,NSE and GFAP antibodies)were used to identify NSCs specific surface markers and muti-differentiation capabilities by immunofluorescence staining.RESULTS Brain derived cells from newborn rats(2 to 3 d)proliferate and aggregate into spherical-shaped clusters with sustained continuous and stable passaging.When BrdU was incorporated into the 5th generation of passaged cells,positive BrdU cells and nestin cells were observed by immunofluorescence staining.After induction of dissociation using 5%fetal bovine serum,positive NF200,NSE and GFAP cells were observed by immunofluorescence staining.CONCLUSION This is a simplified and efficient method for neonatal rat brain-derived neural stem cell culture and identification.
文摘Insulin resistance increases the risk of developing diabetes,and the degree of resistance influences the glycemic control of patients with diabetes.Numerous researchers have focused on improving insulin sensitivity in order to prevent diabetes-related complications and other chronic diseases.Several studies have also linked vitamin D levels to insulin secretion and resistance,given that both vitamin D and its receptor complex play important roles in regulating pancreaticβ-cells.It has been suggested that vitamin D supplementation improves vitamin D levels,but further research is needed to confirm this as neither insulin function nor glycemic control improves when vitamin D levels increase.Magnesium is a cofactor for many enzymes.Although the role of magnesium in the management of diabetes has long been evaluated,it has not yet been determined whether magnesium supplements improve insulin function.However,several researchers have found that patients with good glycemic control have high magnesium levels.Magnesium is closely related to vitamin D and is necessary for the transport and activation of vitamin D in humans.Combined supplementation with vitamin D and magnesium improves glycemic control in patients with diabetes.
文摘Globally,there have been multiple public health emergencies in recent decades.High rates of morbidity,occasionally mortality,and economic instability are usually associated with pandemics.One of the epidemics that has significantly increased morbidity and mortality worldwide is the human immunodeficiency virus(HIV)and acquired immune deficiency syndrome(AIDS)pandemic.HIV has a disproportionately negative impact on key populations.Strong leadership,effective communication,and sound science are necessary for public health emergency(PHE)responses to be successful.These three PHE response pllars are also essential for bridging the HIV response gap among key populations in the setting of restrictive laws.In this review,we explored the importance of these three pillars of successful PHEs responses,and how they are essential to closing the gap in the HIV response among key populations.Leaders must make decisions and instil a sense of authority in the populace during PHEs to foster trust and confidence.Leaders should base their choices on scientific evidence.Effective communication during PHEs should be proactive,polite,imaginative,innovative,and constructive.To address gaps in the HIV response among key populations,leaders must create a supportive environment for effective communication and scientific research,communication should be used to raise awareness of HIV and to dispel stigma and discrimination,while science should provide evidence of efficacy and effectiveness of interventions amongkey populations.

文摘BACKGROUND Histological remission is increasingly accepted as a treatment endpoint in the management of ulcerative colitis(UC).However,the knowledge of histology guidelines and the attitudes towards their use in clinical practice by gastroenterologists and pathologists is unknown.AIM To evaluate the knowledge of histology guidelines and attitudes towards the use of histology in UC by gastroenterologists and pathologists.METHODS A prospective,cross-sectional nationwide survey of gastroenterologists and pathologists who analyse UC specimens was conducted.The survey consisted of 34 questions to assess gastroenterologists’and pathologists’knowledge(score out of 19)and attitudes towards histological assessment in UC.Survey questions were formulated using the European Crohn’s and Colitis position paper on histopathology and the British Society of Gastroenterology biopsy reporting guidelines.It included knowledge of histological assessment of disease activity and dysplasia,knowledge of histological scoring systems for ulcerative colitis,uptake of histology scoring systems in routine practice,attitudes towards the role of histological activity,and the use of histological activity in clinical scenarios.RESULTS Of 89 responders(77 gastroenterologists,12 pathologists),there was almost universal acceptance that histological assessment should form part of UC evaluation[95%gastroenterologists,92%pathologists].However,gastroenterologists reported that 92%of their pathologists do not use a histological scoring system.Utilisation of a formal histological scoring system was preferred by 77%of gastroenterologists and 58%of pathologists.Both groups lacked awareness of the Geboes Score,Nancy Index and Robarts Histopathological Index scoring systems with 91%,87%,and 92%of gastroenterologists respectively;and 83%,83%,and 92%pathologists respectively,being uncertain of scoring systems’remission definitions.Histology knowledge score was not significantly different between gastroenterologists and pathologists[9/19(IQR:8-11)vs 8/19(IQR:7-10),P=0.54].Higher knowledge scores were predicted by hospital attending gastroenterologists(P=0.004),participation in inflammatory bowel disease(IBD)multidisciplinary teams(P=0.009),and self-declared IBD sub-specialist(P=0.03).CONCLUSION Histological remission is a recognised target for both gastroenterologists and pathologists.Despite this,knowledge of histological scoring systems and their utilisation is poor.
文摘Background: Due to their delicious taste, high nutritional content, and health benefits, fruit juices are well-known drinks in many countries and are now an essential component of the modern diet. Objective: Determining the microbiological quality of both packaged and freshly made fruit and milk juices. Method: The spread-plate approach was employed to isolate and count the bacteria. 90 ml of sterile peptone water were blended with 10 ml of well-mixed, packed, and freshly made fruit juices. The samples were sequentially diluted (101 - 105) in accordance with the Indian Manual of Food Microbiological Testing Methods. Results: From eight samples of imported packaged fruit and milk juice, the average of total coliform, staphylococci, and viable bacterial counts were zero, 1.39 × 102, and 2 × 102 CFU/ml, respectively. In contrast, from three samples of locally produced fruit and milk juice, the average of total coliform, staphylococci, and viable bacterial counts were zero, 5.83 × 102, and 2.73 × 103 CFU/ml, respectively. Four samples of handmade prepared fruit and milk juices had a mean of total coliform, staphylococci, and viable bacterial count of 1.441 × 104, 4.1 × 103, and 2.35 × 105 CFU/ml, respectively. Conclusion: 33.3% of the results from microbiological analysis of freshly made fruit and milk juices met the permissible range of the Revised Microbiological Standards for Fruit and Vegetables and Their Products, which were published in 2018 and as well as the Hong Kong Center for Food Safety, whereas 66.7% of the microbiological analyses of freshly prepared fruit and milk juices were above the permissible reference range of GSO standard 2000. 12.5% of the investigated imported and packed fruits and milk juices had one failed test (TSC), which was above the acceptable limit, 87.5% of the tested samples of fruit and milk juices fulfilled the necessary standards of TCC, TVBC, and TSC. 100% of the tested locally manufactured fruit and milk juices complied with TSC, TCC, and TVBC requirements. All investigations showed that freshly made fruit and milk juices were heavily contaminated (Total viable bacterial count, total coliform count, and total staphylococcus count). .

文摘Approximately 180 million people worldwide are affected by Viral hepatitis C, with 350,000 to 500,000 deaths yearly. The present study sought to investigate the prevalence and associated factors of viral hepatitis C (VHC) among the Burundian population during a screening campaign. A total of 629 participants took part in the study, and the prevalence of viral hepatitis C was (8.11%). The associated factors identified as statistically associated were medical and surgical history (P = 0.02) and ear and nose piercing (P = 0.01). 51% of the infected persons were females. The mean age for viral hepatitis C carriage was 46.13 ± 14.3 years and 10.40% of viral hepatitis C carriers were over 50 years old. We found a high viral hepatitis C prevalence in married (9.55%) and divorced (9.38%) participants. The majority of our participants were farmers (60.25%) with a prevalence of viral hepatitis C (7.92%) while 11.54% of the infected participants were not educated. In conclusion, the current study shows a high prevalence of Viral Hepatitis C infection in Burundi. Infection was more likely to occur in older, married, farmer, and illiterates. Unsafe medical and surgical interventions with traditional practitioners were significant risk factors for contracting VHC infection.
文摘Objective: The objective of this study was to investigate the etiologies of infertility and to determine the contribution of hysterosalpingography coupled with ultrasound in the exploration of female infertility at Donka University Hospital. Methodology: This was a prospective descriptive cross-sectional study carried out in the Radiology Department of Donka National Hospital over a period of ten (10) months. It involved 78 women who came to the department for hysterosalpingography and/or pelvic ultrasound examinations, as part of the exploration of infertility. Data collection involved the use of pre-established survey forms to gather information on the parameters studied. Sociodemographic parameters, ultrasound and hysterosalpingography results were studied. A correlation was made between age at marriage and infertility to determine whether early marriage has an impact on primary infertility, with a statically significant result for p value greater than 0.05. Results: The mean age of our patients was 33.7 ± 5.6 years, with extremes of 18 and 35 years. The 18-35 age group was the most represented, with a frequency of 80.7%. The 34% of our patients were married before the age of 18, with a marriage duration ranging from 6 months to 15 years. The indication for investigations was dominated by secondary infertility, with a frequency of 65%, followed by primary infertility (35%). All our women underwent ultrasound-hysterosalpingography, i.e. 100%, in search of the cause of infertility. Ultrasound was pathological in 35.8%. The most common ultrasound lesions were myomas and ovarian dystrophies, with 12.8% each. However, hysterosalpingography was pathological in 35%. Tubal obstructions affected almost a third of our women (29.5%), followed by phimosis and tubo-peritoneal adhesions. Conclusion: Diagnostic evaluation of infertility requires a multidisciplinary approach, including collaboration between infertility gynecologists, radiologists and other infertility specialists. Medical imaging remains indispensable in the evaluation of female infertility.
文摘Rationale:Adrenal histoplasmosis can present as bilateral adrenal enlargement with constitutional symptoms and/or adrenal insufficiency.Often these patients are initially investigated as secondary adrenal metastases before eventually their diagnosis established by histopathological examination of the adrenal tissues.Patients concerns:We report 4 cases of patients aged 55-78 who presented with hypocortisolism and bilateral adrenal masses.Diagnoses:Bilateral adrenal histoplasmosis.Interventions:Three patients received antifungal treatment for at least one year while 1 patient passed away before the initiation of antifungal treatment.Outcomes:Two patients’adrenal function recovered not requiring any steroid replacement,while 1 patient still requires long-term steroid replacement.Lessons:Adrenal histoplasmosis should be excluded in patients from endemic areas presenting with bilateral adrenal masses and adrenal insufficiency.Usually patients have an exposure to bird droppings,bat guano or soil contaminated with histoplasmosis fungi.Histopathological examination of biopsied adrenal tissues is still the gold standard investigation as serology and molecular diagnostic methods are still not widely available in most centers in Malaysia.
文摘Objective:To evaluate the testis and the cauda epididymis after treating both healthy and diabetic rats with rooibos(Aspalathus linearis),honeybush(Cyclopia intermedia),and sutherlandia(Lessertia frutescens),respectively.Methods:Ninety male Wistar rats were randomly divided into nine groups(n=10 per group).Fifty rats were randomized to receive tap water,0.1 M citrate buffer,2.0%fermented rooibos,4.0%fermented honeybush,or 0.2%unfermented sutherlandia.Diabetes was induced via a single intraperitoneal injection of streptozotocin(STZ)at 45 mg/kg in 40 rats.The diabetic rats were randomized to receive tap water,2.0%fermented rooibos,4.0%fermented honeybush,or 0.2%unfermented sutherlandia.Rats were sacrificed after seven weeks of diabetic induction.Blood was collected for hormonal assay,while the testes and caudal epididymis were retrieved for histomorphological evaluations.Results:Diabetic rats treated with 2.0%fermented rooibos exhibited a significant increase in fasting plasma glucose(FPG)versus the vehicle group(P=0.002),and a 3.6%decrease compared to the diabetic control group(P>0.05).Diabetic rats treated with honeybush or sutherlandia showed 23.6%and 15.4%decrease in FPG when compared to the diabetic control group,respectively(both P>0.05).The diabetic control rats had a significant decrease in the percentage of histologically normal seminiferous tubules compared to the control group(P=0.049).There was 21.0%,14.0%,and 5.4%rise in the percentage of normal seminiferous tubules in diabetic rats receiving rooibos,honeybush or sutherlandia,respectively,compared to the diabetic control group.The infusion control groups(rooibos,honeybush and sutherlandia)showed normal seminiferous tubules,presence of spermatozoa in the epididymal lumen,and had normal overall architecture.Both testicular and epididymal morphology were altered in the diabetic control group,but these disruptions were mildly ameliorated by rooibos,honeybush,and sutherlandia.Conclusions:The detrimental effects of diabetes on the histomorphological architecture of the testis and epididymis are mildly ameliorated by the infusions(2.0%fermented rooibos,4.0%fermented honeybush,and 0.2%unfermented sutherlandia).
文摘Studies have indicated that lack of regular physical exercise and not adhering to a health-promot- ing lifestyle among student nurses are barriers to their encouraging patients to exercise. On the other hand, nurses who personally embrace physical activity are more likely to encourage their patients to improve their health through physical activity or diet. As a result, promoting an active and healthy lifestyle among student nurses is important because this has a crucial role in their subsequently encouraging healthy lifestyles among their patients. The aims of this study were to determine the physical activity levels and health-promoting lifestyles among student nurses in Malaysia, and to investigate whether there was a correlation between the physical activity levels of student nurses and their lifestyle habits. Further investigation was also carried out to correlate lifestyle habits with physical activity during weekdays and at the weekends. This study involved 189 student nurses who were pursuing Diplomas and Bachelor Degrees in local government universities. The Yamax Digi-Walker pedometer was used to measure physical activity, while the Health-Promoting Lifestyle Profile (HPLP) II questionnaire was used to assess the health-pro- moting lifestyles of the participants. The HPLP II consisted of six sub-scales which included health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, and stress management. According to the results on physical activity, the student nurses had a mean of 8275.97 ± 2210.174 steps per day and were thus categorised as somewhat active. Additionally, the student nurses were found to be more active during weekends (M = 8389.75, SD = 2689.12) as compared to weekdays (M = 8230.46, SD = 2353.97). According to previous studies, both step counts are classified in the “somewhat active” category. Overall, the results for HPLP II showed that student nurses students in Malaysia had a positive health-promoting lifestyle with a score of 2.58 ± 0.34 on a 4-point Likert scale. The highest score was reported in spiritual growth, with a score of 2.92 ± 0.43. Meanwhile, physical activity was observed to be the lowest, with a score of 1.74 ± 0.39. The results found no correlation between physical activity and overall health-promoting lifestyle among student nurses in Malaysia (r = 0.06, n = 189, p < 0.37). However, there was a significant relationship between physical activity (measured by the pedometer) and physical activity habit (measured through the questionnaire) among the student nurses (r = 0.24, n = 189, p < 0.01). According to the findings, when the participants indicated in the questionnaire that they were active physically, the pedometer readings also showed a corresponding similarity in terms of their daily physical activities.

文摘Mitogen-activated protein kinases(MAPKs) are the main regulators of cellular proliferation, growth, and survival in physiological or pathological conditions. Aberrant MAPK signaling plays a pivotal role in carcinogenesis, which leads to development and progression of human cancer. Dual-specificity phosphatase 6(DUSP6), a member of the MAPK phosphatase family, interacts with specifically targeted extracellular signal-regulated kinase 1/2 via negative feedback regulation in the MAPK pathway of mammalian cells. This phosphatase functions in a dual manner, pro-oncogenic or tumor-suppressive, depending on the type of cancer. To date, the tumor-suppressive role of DUSP6 has been demonstrated in pancreatic cancer, non-small cell lung cancer, esophageal squamous cell and nasopharyngeal carcinoma, and ovarian cancer. Its pro-oncogenic role has been observed in human glioblastoma, thyroid carcinoma, breast cancer, and acute myeloid carcinoma. Both roles of DUSP6 have been documented in malignant melanoma depending on the histological subtype of the cancer. Loss-or gain-of-function effects of DUSP6 in these cancers highlights the significance of this phosphatase in carcinogenesis. Development of methods that use the DUSP6 gene as a therapeutic target for cancer treatment or as a prognostic factor for diagnosis and evaluation of cancer treatment outcome has great potential. This review focuses on molecular characteristics of the DUSP6 gene and its role in cancers in the purview of development, progression, and cancer treatment outcome.

文摘AIM To investigate the role of suppressor of cytokine signaling 1(SOCS1)in regulating MET-mediated invasive potential of hepatocellular carcinoma(HCC)cells.METHODSStable derivatives of mouse(Hepa1-6)and human(hep3B,Hep G2)HCC cell lines expressing SOCS1or control vector were evaluated for their ability to migrate towards hepatocyte growth factor(HGF)in the transwell migration assay,invade extracellular matrix in response to HGF stimulation in a 3-D invasion assay by confocal microscopy,and to undergo anchorageindependent proliferation in semisolid agar.Following intravenous and intrasplenic inoculation into NOD.scid.gamma mice,the ability of Hepa cells to form othotopic tumors was evaluated.Following HGF stimulation of Hepa and Hep3B cells,expression of proteins implicated in epithelial-to-mesenchymal transition was evaluated by western blot and qR T-PCR.RESULTS SOCS1 expression in mouse and human HCC cells inhibited HGF-induced migration through matrigel.In the 3-D invasion assay,HGF stimulation induced invasion of HCC cells across type-Ⅰcollagen matrix,and SOCS1expression significantly reduced the depth of invasion.SOCS1 expression also reduced the number and size of colonies formed by anchorage-independent growth in semisolid agar.Following intravenous inoculation,control Hepa cell formed large tumor nodules that obliterated the liver whereas the SOCS1-expressing Hepa cells formed significantly smaller nodules.Tumors formed by SOCS1-expressing cells showed reduced phosphorylation of STAT3 and ERK that was accompanied by reduced levels of MET protein expression.HGF stimulated Hepa cells expressing SOCS1 showed increased expression of E-cadherin and decreased expression of EGR1,SNAI1and ZEB1.Comparable results were obtained with Hep3B cells.SOCS1 expressing HCC cells also showed reduced levels of EGR1 and SNAI1 transcripts.CONCLUSION Our findings indicate that loss of SOCS1-dependent control over epithelial-to-mesenchymal transition may contribute to MET-mediated migration,invasion and metastatic growth of HCC.
