Cryptosporidiosis is an emerging food and waterborne zoonotic protozoan disease that has been detected in both human and animal populations all over the world. The source of infection is exogenous, and the ingestion of contaminated food and water is the principal mode of transmission. The oocysts of Cryptosporidium are abundant and pervasive in ambient water, where they can survive for months. It prefers epithelial cells found in the digestive tracts of a wide range of hosts. Waterborne transmission through drinking water or a swimming pool is common, resulting in outbreaks in several nations throughout the world. The disease can manifest itself in sporadic or epidemic forms. The infection has been recorded in immunocompetent and immunocompromised individuals. The watery diarrhea, abdominal cramps, nausea, anorexia and low grade fever are most commonly observed symptoms. The laboratory help is required to make an unequivocal diagnosis of disease. The preventive strategies include excellent hygienic measures to avoid the contamination of food and water by oocysts of Cryptosporidium. In addition, the role of veterinarian is highly imperative for the management of disease in domestic animals.","PeriodicalId":127077,"journal":{"name":"MOJ Biology and Medicine","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124393848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genital herpes infection is a major concern in pregnancy due to the risk of neonatal transmission. Materials and methods: A descriptive cross-sectional survey was conducted from August 2016 to March 2017 in some hospitals and health centers to assess the seroprevalence and risk factors of herpes simplex virus type 2 infection among pregnant women attending antenatal care in Dhamar city, Yemen. After taking written consent, socio-demographic, behavioral and obstetric history along with blood samples were collected from 200 pregnant women using a pre-structured questionnaire. Sera were analyzed for HSV-2 specific IgG using Electro-Chemiluminescence Immunoassay (ECLIA) method. Results: The overall seroprevalence of HSV-2 infection was 6 % (12/200) among pregnant women in Dhamar city. Levels of education and some obstetrical history such as numbers previous abortion (P=0.03), stillbirth (P=0.001). Although the study showed, there are significant differences in some symptoms, such as itching (P=0.02) and inflammation during urination (P=0.03). Conclusion: Overall, the seroprevalence of HSV-2 infection among pregnant women in Dhamar city is low. There is a critical need to adopt screening of HSV-2 into the antenatal profile tests. There is also need for more health education of this virus infection, methods of transmission, associated risk factors, and effective prevention and control strategies.","PeriodicalId":127077,"journal":{"name":"MOJ Biology and Medicine","volume":"65 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123042028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of Lead (Pb) and Cadmium (Cd) at different concentrations were investigated over a period of eight weeks. Chloride salts of Pb and Cd were added singly and in combination to soil samples at room temperature (270C) in different polythene bags. Samples were taken from the bags at two weeks interval and measurements were taken of the microbial biomass carbon (MBC). The results showed that there was a significant decrease in the microbial biomass carbon for all treated soils from the second week to the sixth week. But there was an observed increase in microbial biomass carbon on the eight week. At the sixth week, 2000mgkg-1Pb and 40mgkg-1Cd gave the most significant decrease (P < 0.05) in microbial biomass carbon of 98%.","PeriodicalId":127077,"journal":{"name":"MOJ Biology and Medicine","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125376342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this experimental study cell culture for differentiation assay performed in 6 well pellets by DMEM high glucose medium with a supplement of 10% FBS and synovial fluid 5% and 10% of medium add to pellets for 21 days. Total cellular RNA extracted was used for analysis by RT-PCR. Alcian blue staining confirmed the chondrogenic differentiation. MTT assay results in this study showed that the cells proliferation gradually increased from 1st day to 21st days on the electrospun nanofibrous scaffold. Cellular attachment and proliferation of hMSCs showed higher rate on PCL substrate, modified with Helium cold atmospheric plasma, compared to the unmodified and control group at the first day to 21st days. Chondrogenic differentiation confirmed by alcian blue staining, and show high degree of conversion to the chondrocyte. MTT assay and the expression of chondrogenic specific genes Collagen type П and Has-2 in comparison with control groups demonstrated cell survival ability, proliferation and cell differentiation by synovial fluid.","PeriodicalId":127077,"journal":{"name":"MOJ Biology and Medicine","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125445035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
