Although many efforts have lain to explore better yielding and nutritionally rich cultivars with suitable modern cultivation techniques but still have to find the desired outcome. Thus, it’s necessary to conduct further research to identify the high-yielding and nutritious capsicum cultivars in Bangladesh. An experiment was conducted from July 2021 to June 2022 at the Bangladesh Institute of Research and Training on Applied Nutrition (BIRTAN) research field with three cultivars of capsicum: B<sub>0</sub> = California Wonder, B<sub>1</sub> = BARI Misti Morich-1 and B<sub>2</sub> = BARI Misti Morich-2 and three mulching: T<sub>0</sub> = No mulching, T<sub>1</sub> = Water hyacinth, T<sub>2</sub> = Poly Mulching in randomized complete block design with three replications to identify better quality capsicum cultivar and suitable mulching material. Among cultivars the BARI Misti Morich-2 (B<sub>2</sub>) showed increased agronomic parameters like number of branches and effective branches per plant, leaves length and width, consequently yield and yield contributing traits were also enhanced like fruits per plant, fruit length, fruit diameter and yield per plant (25.97%, 4.54%, 3.64% and 21.43%, respectively). Poly Mulching (T<sub>2</sub>) increased agronomic traits, yield traits and yield (0.61 kg) than BARI Misti Morich-1 (T<sub>1</sub>). The combined effect of B<sub>2</sub>T<sub>2</sub> increased the number of branches per plant, effective branches per plant, leaves length and breadth by 40%, 90%, 15.57% and 26.22%, respectively, hence resulting in an increased yield of 20%. BARI Misti Morich-2 cultivar showed an increase in Fe, Zn and Vitamin-C content of 26.24% and 23.10%, 8.82% and 5.14%, and 6.03% and 5.74% than B0 and B1 cultivars, respectively. Therefore, BARI Misti Morich-2 exhibited the improved agronomic, yield and nutritional traits of capsicum under poly mulching among other cultivars in Bangladesh.展开更多

Objectives: To determine the nutrient contents and heavy metals of five commonly consumed spices, namely turmeric (Curcuma longa), bay leaf (Laurus nobilis), red chili (Capsicum annuum), coriander (Coriander sativum), and black cumin (Nigella sativa) were collected from the local market of Northern zone, Bangladesh and were analyzed. Methods: Nutrient composition was assessed by proximate analysis, trace and heavy metals by atomic absorption spectrophotometry while the indophenol method was used to determine vitamin C. Result: The results revealed that spices are good sources of carbohydrate, fiber, and fat. The highest levels of carbohydrates, dietary fiber, protein, and fat were observed in turmeric (71.1%), black cumin (40.0%), red chili (16.77%), and coriander (17.8%) respectively. Vitamin C was present in trace amounts ranging from 0.04 to 0.1 mg/100g, except black cumin (35.0 mg/100g). Essential trace minerals like sodium, potassium, calcium, magnesium, and iron were significantly present in black cumin and bay leaf. Most of the heavy metal levels in the spices were appreciable amounts i.e. much lesser than the statutory safe limit approved by WHO and FAO for some of the samples. Conclusion: The current study concluded that the investigated spices are nutritionally rich, and heavy metal levels in the examined samples are safe for human consumption.展开更多

Higher starting MOIs did not always produce more bacterial internalization. The bacterial invasion effects varied with different bacterial strains and host cell lines. E. coli O157:H7 did invade human ileocecum HCT-8 cells.Conclusions: This study shows that these bacteria possess different invasive patterns at various starting MOIs and also in different cell lines. The results could help to figure out the appropriate infectious doses of the bacteria in animal assays and in vaccine clinical trials. The bacterial invasion kinetics is also valuable in evaluating the safety and efficacy of live attenuated bacterial vaccines.展开更多

Our work focuses on the exploitation of four cases of patients with NF-1 who were enrolled in the paediatric neurology consultation at Rabat Children’s Hospital. They are two infants and two children. Otherwise the diagnosis was made in front of the existence of café au lait and lentiginous spots in two boys, also the existence of café au lait spots and abnormalities in brain imaging in two girls. Thus an evolution was marked by a favorable outcome for three patients and neurological sequelae in one patient.展开更多

We will present in this article a review of the literature concerning normal early childhood development, focus firstly in normal development’s steps, the importance of first experiences and first aid with a stable and caring attachment figure. second, we will describe the various developmental disorders, occurring during this age group which extends from birth to 6 years and based on the DSM5 classification, namely that developmental delay may concern only one aspect of development (e.g. language delay or motor delay specifically) or concern the different aspects of development (overall development delay). The dynamics of development is also important to clarify because schematically we contrast the pathologies fixed to progressive pathologies (where we find the concepts of stagnation or regression in the development of the child). We will discuss in the third chapter, the interest of early detection as well as the multiple clinical and psychometric diagnostic tools, which aim to detect any delay or disorder in order to initiate appropriate care and minimize the long-term consequences.</span> </p>展开更多

Methods: This work has been carried out to study the action of C. crista extracts from nonpolar to polar solvents toward inhibition of oxidative stress, cholinergic and amyloidosis. The antioxidant activity was studied using DPPH total antioxidant assay; cholinergic assay by Ellman's method and anti-amyloidogenic assay by thioflavin-T fluorescence and transmission electron microscopy. Results: The quantification of polyphenols was carried out following C. crista methanolic extract(CCMeOH) HPLC fingerprinting, along with LC-MS and elucidated by MS LAMPS database. GC-MS of CCMeOH was screened for potential moieties. In vitro experimental results showed that the CCMe OH was potential extract that exhibited active inhibition of antioxidant property, cholinergic enzymes acetylcholinesterase and butyrylcholinesterase. For anti-amyloidogenic evaluations, among all the extracts, the CCMe OH was found to have the potential toward inhibiting the oligomers, fibrillation of Aβ42 with good defibrillation of amyloid cascading properties. Conclusions: These results are also supported by the presence of polyphenols as the active ingredients. Multi-potent target drug therapy is a promising option in treating the Alzheimer's diseases. Methanolic extract of C. crista shows potential activity against cholinergic enzymes, Aβ42 aggregation with antioxidant activity.展开更多

In mo...Multicellular organisms use chemical messengers to transmit signals among organelles and to other cells. Relatively small hydrophobic molecules such as lipids are excellent candidates for this signaling purpose. In most proteins, palmitic acid and other saturated and some unsaturated fatty acids are esterified to the free thiol of cysteines and to the N-amide terminal. This palmitoylation process enhances the surface hydrophobicity and membrane affinity of protein substrates and plays important roles in modulating proteins’ trafficking, stability, and sorting etc. Protein palmitoylation has been involved in numerous cellular processes, including signaling, apoptosis, and neuronal transmission. The palmitoylation process is involved in multiple diseases such as Huntington’s disease, various cardiovascular and T-cell mediated immune disorders, as well as cancer. Protein palmitoylation through the thioester (S-acylation) is unique in that it is the only reversible lipid modification. Our study on lipopolysaccharide (LPS) and deoxynivalenol (DON) treatment to rats provides some insights to the complex role of protein palmitoylation in chemical and microbial toxicity. In contrast, myrisoylated proteins contain the 14-carbon fatty acid myristate attached via amide linkage to the N-terminal glycine residue of protein, and occur cotranslationally. The bacterial outer membrane enzyme lipid A palmitoyltransferase (PagP) confers resistance to host immune defenses by transferring a palmitate chain from a phospholipid to the lipid A component of LPS. PagP is sensitive to cationic antimicrobial peptides (CAMP) which are included among the products of the Toll-like receptor 4 (TLR4) signal transduction pathway. This modification of lipid A with a palmitate appears to both and protects the pathogenic bacteria from host immune defenses and attenuates the activation of those same defenses through the TLR4 signal transduction pathway.展开更多

It also leads to chronic health problems. This cross-sectional study aimed to determine the prevalence of contagious diseases in children of 5 - 12 years from five government primary schools (class II to V) in Tangail City, Bangladesh using multistage sampling method. Data were collected using a carry home questionnaire and diseases screening examination was done in the school. Prevalence of common contagious diseases was calculated. A total of 84 students were screened to have contagious diseases by clinical examination, giving a prevalence rate of 8.76% from 958 participated school children. The prevalence of contagious disease among the affected children in the study was found 30.95% for scabies, while 20.24% for influenza and 7.14%, 9.52%, 15.48%, 5.95%, & 10.71% for typhoid, chicken pox, measles, pneumonia, and whooping cough, respectively. Anthropometric measurements were recorded which indicated that 48.8% of children were well-nourished and 21.4%, 17.9%, & 11.9% of children were underweight, stunted, and wasted, respectively. However, these data are extremely important to define the problem and to design proper intervention strategies.展开更多

The development of low-cost alternatives for recovery of these proteins is fundamental for small producers who cannot apply expensive techniques. The present study investigated the complex coacervation technique as a cheap technology to recover proteins from sweet whey using carboxymethylcellulose, and the coacervate used as an ingredient in the formulation of probiotic fermented milk. The nutritional properties of whey-carboxymethylcellulose coacervates (WP-CMC) were evaluated in trials with animals (rats) using casein as a reference. All these parameters—the coefficient of feed efficiency (CEA), protein digestibility-corrected amino acid score (PDCAAS), and net protein ratio (NPR), as well as weight gain—were determined to evaluate protein quality. A sensory acceptance test was applied to evaluate the sensory characteristics of the product. The complex coacervation technique recovered 86% of the protein from sweet whey. No significant (p > 0.05) differences were observed in the biological tests for both groups (WP-CMC and Casein groups) when NPR (4.98 to 5.04), digestibility (92.35 to 90.64), and CEA (0.40 to 0.42) were evaluated. Probiotic fermented milk beverage containing WP-CMC (0.78%) and guar gum (0.68%) presented good acceptability as determined by sensory evaluation. WP-CMC can be considered an ingredient with high nutritional and biological value that could be applied in probiotic fermented milk as an alternative to small producers to allocate the residual whey from cheese manufacture.展开更多

文摘Objective:To evaluate the antidiabetic and antioxidant potential of Emblica officinalis(E.officinalis)fruit on normal and type 2 diabetic rats.Methods:Type 2 diabetes was induced into the male Long-Evans rats.The rats were divided into nine groups including control groups receiving water,type 2 diabetic controls,type 2 diabetic rats treated with glibenclamide(T2GT)and type 2diabetic rats treated with aqueous extract of fruit pulp of E.officinalis.They were fed orally for8 weeks with a single feeding.Blood was collected by cutting the tail tip on 0 and 28 days and by decapitation on 56 day.Packed red blood cells and serum were used for evaluating different biochemical parameters.Results:Four weeks administration of aqueous extract of E.officinalis improved oral glucose tolerance in type 2 rats and after 8 weeks it caused significant(P<0.007)reduction in fasting serum glucose level compared to 0 day.Triglycerides decreased by 14%but there was no significant change in serum ALT,creatinine,cholesterol and insulin level in any group.Furthermore,reduced erythrocyte malondialdehyde level showed no significant change(P<0.07)but reduced glutathione content was found to be increased significantly(P<0.05).Conclusions:The aqueous extract of E.officinalis has a promising antidiabetic and antioxidant properties and may be considered for further clinical studies in drug development.
文摘Objective: To refine the infectious doses of enteric bacterial pathogens in animal assays and vaccine clinical trials by studying the invasion kinetics of five bacterial pathogens with human intestinal cells.Methods: Utilizing in vitro cultured cell invasion assays with gentamicin-killing step,the invasive effects were analyzed in foodborne pathogens including Salmonella,Shigella, Yersinia, Escherichia coli(E. coli) O157 and opportunistic pathogens Citrobacter in human embryonic intestine 407 cells and ileocecum HCT-8 cells at multiplicities of infection(MOIs) of 0.04–4 000.00 E. coli HS served as a noninvasive control.Results: The study results showed that the bacterial invasive efficiency and the average number of internalized bacteria per host cell changed with different starting MOIs. Higher starting MOIs did not always produce more bacterial internalization. The bacterial invasion effects varied with different bacterial strains and host cell lines. E. coli O157:H7 did invade human ileocecum HCT-8 cells.Conclusions: This study shows that these bacteria possess different invasive patterns at various starting MOIs and also in different cell lines. The results could help to figure out the appropriate infectious doses of the bacteria in animal assays and in vaccine clinical trials. The bacterial invasion kinetics is also valuable in evaluating the safety and efficacy of live attenuated bacterial vaccines.
文摘The study was carried out to develop and compare Ginger candy from fresh indigenous and China Ginger. Ginger was immersed into the sugar solution with the concentrations of 50%, 60% and 70% sugar solution. Moisture, ash, protein, fat, crude fiber and total sugar content and organoleptic quality and microbial status of the prepared candy were analyzed. Moisture, ash, protein, fat and crude fiber content was found to be lower with increased concentration of sugar solution used, whereas total sugar content was found to be higher. Total bacterial count was increased with increasing the concentration of sugar solution. The best characteristic of Ginger candy was found with 50% sugar solution, with highest nutrient and lowest microbial load than candy prepared with 60% and 70% sugar solution.

文摘Neurofibromatosis Type 1 (NF-1 or Von Recklinghausen disease) is an autosomal dominant genetic disease, characterized by an extreme variability of its clinical expression which is also found in the same family. Our work focuses on the exploitation of four cases of patients with NF-1 who were enrolled in the paediatric neurology consultation at Rabat Children’s Hospital. They are two infants and two children. Otherwise the diagnosis was made in front of the existence of café au lait and lentiginous spots in two boys, also the existence of café au lait spots and abnormalities in brain imaging in two girls. Thus an evolution was marked by a favorable outcome for three patients and neurological sequelae in one patient.

Especially during the first six years of life in an adequate environment rich in exchange and inter</span><span>action. We will present in this article a review of the literature concerning normal early childhood development, focus firstly in normal development’s steps, the importance of first experiences and first aid with a stable and caring attachment figure. second, we will describe the various developmental disorders, occurring during this age group which extends from birth to 6 years and based on the DSM5 classification, namely that developmental delay may concern only one aspect of development (e.g. language delay or motor delay specifically) or concern the different aspects of development (overall development delay). The dynamics of development is also important to clarify because schematically we contrast the pathologies fixed to progressive pathologies (where we find the concepts of stagnation or regression in the development of the child). We will discuss in the third chapter, the interest of early detection as well as the multiple clinical and psychometric diagnostic tools, which aim to detect any delay or disorder in order to initiate appropriate care and minimize the long-term consequences.</span> </p>

文摘Objective: To screen plant extract fractions and elucidate the components present in Caesalpinia crista(C. crista) leaves for cholinergic and anti-amyloidogenic activities for the treatment of Alzheimer's diseases. Methods: This work has been carried out to study the action of C. crista extracts from nonpolar to polar solvents toward inhibition of oxidative stress, cholinergic and amyloidosis. The antioxidant activity was studied using DPPH total antioxidant assay; cholinergic assay by Ellman's method and anti-amyloidogenic assay by thioflavin-T fluorescence and transmission electron microscopy. Results: The quantification of polyphenols was carried out following C. crista methanolic extract(CCMeOH) HPLC fingerprinting, along with LC-MS and elucidated by MS LAMPS database. GC-MS of CCMeOH was screened for potential moieties. In vitro experimental results showed that the CCMe OH was potential extract that exhibited active inhibition of antioxidant property, cholinergic enzymes acetylcholinesterase and butyrylcholinesterase. For anti-amyloidogenic evaluations, among all the extracts, the CCMe OH was found to have the potential toward inhibiting the oligomers, fibrillation of Aβ42 with good defibrillation of amyloid cascading properties. Conclusions: These results are also supported by the presence of polyphenols as the active ingredients. Multi-potent target drug therapy is a promising option in treating the Alzheimer's diseases. Methanolic extract of C. crista shows potential activity against cholinergic enzymes, Aβ42 aggregation with antioxidant activity.
文摘Multicellular organisms use chemical messengers to transmit signals among organelles and to other cells. Relatively small hydrophobic molecules such as lipids are excellent candidates for this signaling purpose. In most proteins, palmitic acid and other saturated and some unsaturated fatty acids are esterified to the free thiol of cysteines and to the N-amide terminal. This palmitoylation process enhances the surface hydrophobicity and membrane affinity of protein substrates and plays important roles in modulating proteins’ trafficking, stability, and sorting etc. Protein palmitoylation has been involved in numerous cellular processes, including signaling, apoptosis, and neuronal transmission. The palmitoylation process is involved in multiple diseases such as Huntington’s disease, various cardiovascular and T-cell mediated immune disorders, as well as cancer. Protein palmitoylation through the thioester (S-acylation) is unique in that it is the only reversible lipid modification. Our study on lipopolysaccharide (LPS) and deoxynivalenol (DON) treatment to rats provides some insights to the complex role of protein palmitoylation in chemical and microbial toxicity. In contrast, myrisoylated proteins contain the 14-carbon fatty acid myristate attached via amide linkage to the N-terminal glycine residue of protein, and occur cotranslationally. The bacterial outer membrane enzyme lipid A palmitoyltransferase (PagP) confers resistance to host immune defenses by transferring a palmitate chain from a phospholipid to the lipid A component of LPS. PagP is sensitive to cationic antimicrobial peptides (CAMP) which are included among the products of the Toll-like receptor 4 (TLR4) signal transduction pathway. This modification of lipid A with a palmitate appears to both and protects the pathogenic bacteria from host immune defenses and attenuates the activation of those same defenses through the TLR4 signal transduction pathway.
文摘Children are becoming increasingly vulnerable to contagious disease around the world. It also leads to chronic health problems. This cross-sectional study aimed to determine the prevalence of contagious diseases in children of 5 - 12 years from five government primary schools (class II to V) in Tangail City, Bangladesh using multistage sampling method. Data were collected using a carry home questionnaire and diseases screening examination was done in the school. Prevalence of common contagious diseases was calculated. A total of 84 students were screened to have contagious diseases by clinical examination, giving a prevalence rate of 8.76% from 958 participated school children. The prevalence of contagious disease among the affected children in the study was found 30.95% for scabies, while 20.24% for influenza and 7.14%, 9.52%, 15.48%, 5.95%, & 10.71% for typhoid, chicken pox, measles, pneumonia, and whooping cough, respectively. Anthropometric measurements were recorded which indicated that 48.8% of children were well-nourished and 21.4%, 17.9%, & 11.9% of children were underweight, stunted, and wasted, respectively. However, these data are extremely important to define the problem and to design proper intervention strategies.
文摘Discharge of whey proteins is still a current practice by small cheese producers. The development of low-cost alternatives for recovery of these proteins is fundamental for small producers who cannot apply expensive techniques. The present study investigated the complex coacervation technique as a cheap technology to recover proteins from sweet whey using carboxymethylcellulose, and the coacervate used as an ingredient in the formulation of probiotic fermented milk. The nutritional properties of whey-carboxymethylcellulose coacervates (WP-CMC) were evaluated in trials with animals (rats) using casein as a reference. All these parameters—the coefficient of feed efficiency (CEA), protein digestibility-corrected amino acid score (PDCAAS), and net protein ratio (NPR), as well as weight gain—were determined to evaluate protein quality. A sensory acceptance test was applied to evaluate the sensory characteristics of the product. The complex coacervation technique recovered 86% of the protein from sweet whey. No significant (p > 0.05) differences were observed in the biological tests for both groups (WP-CMC and Casein groups) when NPR (4.98 to 5.04), digestibility (92.35 to 90.64), and CEA (0.40 to 0.42) were evaluated. Probiotic fermented milk beverage containing WP-CMC (0.78%) and guar gum (0.68%) presented good acceptability as determined by sensory evaluation. WP-CMC can be considered an ingredient with high nutritional and biological value that could be applied in probiotic fermented milk as an alternative to small producers to allocate the residual whey from cheese manufacture.
