This similarity law is valid in the cases of wind waves as well as swells under natural sea states. On the basis of the 3/5-power law combined with the well-known 3/2-power law I it is shown that the wave-induced wind stress increases rapidly with wave age, indicating that the traditional observations or analytic techniques have only given the turbulent Reynolds stress induced by short wind waves, but excluded the long-wave-induced wind stress. The latter constitutes a small fraction to the total wind stress when the wave age is smaller than 1.0. The increase of sea-surface roughness with wave age can be attributed to wave breaking.展开更多

The authors prospectively studied the role of phacoemulsification and intraocular lens implantation on 25 patients by observing visual acuity, ocular alignment, binocular vision and diplopia pre-, 1 month post- and 3 months post-operation. The patients underwent follow-up for three months. Postoperatively, one patient had a corrected visual acuity of 20/50, and 24 patients had 20/40 or better. The ocular alignment, binocular vision and diplopia were resolved spontaneously. Phacoemulsification and intraocular lens implantation performed together is effective on sensory exotropia subsequent to senile cataract.展开更多

Methods: Highly purified spermatogonia were isolated from 9-day-old rats, pachytene spermatocytes and round spermatids from adult rats by sedimentation velocity at unit gravity, using 2%-4% BSA gradient in DMEM/F12 medium. A mRNA differential display method was used for screening the stage-specific expression gene. Results: Nineteen differentially expressed cDNA fragments were obtained. After excluding the false positive cDNA fragments by dot blot, 13 cDNAs were selected to clone and sequence. To obtain longer cDNAs, six ESTs were used to screen the rat testis λ-zap II cDNA library. Two longer cDNA fragments, designated as LY21 and LM66, were obtained. The analysis with DNAMAN software indicated that LY21 had a long open reading frame coding 372 amino acids while LM66 had no long open reading frame. LY21 were highly homologous with hnRNP H1. To observe the expression patterns of LY21 gene in the testicular cells, we performed in situ hybridization on testis sections from adult rats. The LY21 gene expression was found in the spermatogonia and primary spermatocytes.Conclusion: This study indicated that LY21 gene was associated with spermatogenesis. Further studies will be needed to explore the function of LY21.展开更多

Methods: We carried out a cross-sectional study extending from the period of 2009 to 2013 in the Internal Medicine department of the “G” Point University Hospital in Bamako. Included were all records of hospitalized patients with a central temperature greater than 37°C in the morning and 37°C in the evening, resting for 15 minutes, fasting for more than 2 hours, and absence of antipyretic treatment. We include all the patients of the study period with fever greater than 37.5°C in the morning and 37.8°C in the evening, resting for 15 minutes, fasting for more than 2 hours, and absence of antipyretic treatment, which have more than 21 days and measured on several occasions. The data were collected on a survey sheet. Data entry and analysis was done on SPSS software. Results: We recorded 243 fever cases out of 2155 hospitalizations, a prevalence rate of 11.2%. There were 128 men and 115 women with an average age of 43 years (range, 15 to 84 years), a modal class of 37 to 47 years, and a sex ratio of 1.11. The infectious etiologies accounted for 81% followed by neoplastic causes 09.6% and inflammatory 01.2% of cases. HIV infection was found in 26.4% of patients, malaria 13.5% and urinary tract infections 10.2%). Gram negative bacilli 88% consisted mainly of Escherichia coli (56%) and Klebsiella pneumoniae (20%).展开更多

Given the aging population, the rate of incidence is increasing among the elderly. Objectives: The study aims to determine the prevalence of heart failure in the elderly;to describe the clinical aspects;describe etiologies;describe the therapeutic aspects;and describe the evolution of heart failure among the elderly. Method: This was a retrospective study over five years on the operating records of patients hospitalized in the internal medicine department of Hospital Point G. Result: The study included records of 22 elderly patients who were with heart failure of a total of 595 patients hospitalized from 1st January 2008 to 31st December 2012. The prevalence rate was 3.7%, and the average age was 67 ± 7.79 years. The sex ratio was equal to 1. HTA accounted for the cardiovascular risk factors in 77.3%. 72.7% of patients had the symptom of dyspnea and 95.5% of patients had the symptom of IMO. According to the cardiac ultrasound, dilation of the OG represented 68.2% of cases, followed by impaired LVEF (63.6%). The etiologies of IC were represented by dilated cardiomyopathy (95.5%), followed by 13.6% in cardiothyreosis. Drug treatment was dominated by the use of diuretics, ACE inhibitors and sodium diet respectively 95.5%;81.8% and 45.5% of cases. The clinical outcome was favorable in 73%. We recorded four (4) cases of death, which accounted for 18% of patients.展开更多

In Mali, from March, 2007 to February, 2008, in National Center for Disease Control and Prevention, 19.2% of hospitalized patients (24/125) received long-term corticosteroid therapy. Until now, the department of internal medicine of the university hospital of Point G hasn’t done any research on the corticosteroid therapy specially. Therefore, we initiated this work to evaluate our practice of prescription of corticosteroid. The target of the study was to evaluate practical activity of prescription of corticosteroid of internal medicine. Methods: Based on all hospitalized patient materials of the department of internal medicine of Point G regional university central hospital during January 2009-December 2013, we initiated this retrospective and descriptive study. This study was based on all hospitalized patients receiving corticosteroid in the time of researching, without distinguishing their sex or age. Results: During the period of study, the department of internal medicine of point G regional central hospital had received 2155 patients;64 were eligible: prevalence of 2.97%. Most patients were female, accounting for 87.5% with a sex-ratio of 0.14. The average age of our patients was 39.11 ± 16.92 years, ranging from 14 to 97 years. Physicians enrolled in the study Specialized Diploma (DES) and Internal represented 79.7% of prescribers. As pretreatment assessment, only 2 patients (3.12%) had carried out all of the standard balance (NFS, electrolytes, calcium, blood glucose and serum protein). The most common glucocorticoide was prednisone. Solid tumors represented 31.25% (20 cases) of the diseases treated, followed by systemic lupus erythematosus with 15.62% (10 cases). In addition, there are two cases of adrenals insufficiency (3.1%). In Point G internal medicine, pre-therapy evaluation and methods about corticosteroids therapy were insufficient and different.展开更多
