asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
BACKGROUND Despite the reduction in reported incidence of tuberculosis globally, the burden of pulmonary tuberculosis (PTB) remains high in low- and middle- income countries, including China. The current study aims to evaluate the distribution and trend of PTB incidence in Xinjiang, the region with the highest PTB burden in China. METHODS We identified all confirmed PTB case records reported ...
Background and purpose: Tuberculosis (TB) is created by Mycobacterium tuberculosis. Application of Geographical Information System (GIS) is of great benefit in understanding the geographical pattern of TB and strengthens its control programs. This study was performed in Guilan, Iran to determine the geographical pattern of TB in this province. Materials and methods: The present ecological stu...
INTRODUCTION This study was conducted in the Boland health district of the Cape Winelands of South Africa where there is a high tuberculosis incidence and prevalence. A survey conducted on 211 farms in the study district during 1998, reported that 65% (n = 9042) of all workers on these farms, were temporarily employed. Temporary farm workers live in communities either within or the outskirts of...
BACKGROUND Multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) hinder the progress of TB control. OBJECTIVE To track the trend of drug-resistant tuberculosis (DR-TB) prevalence in Zhejiang Province from 1999 to 2013, and identify risk factors of resistance to second-line drugs among MDR-TB patients. DESIGN Four DR-TB surveys had been done in Zhejia...
Background: Tuberculosis with high prevalence in HIV/AIDS patients is the main reason for morbidity and mortality in these patients. About one-third of patients with HIV infection have concomitant tuberculosis. Lack of appropriate infection control on many social and economic communities will impose. Comprehensive study on the effects of anti-tuberculosis drugs in patients with HIV infecti...
background: there are many reports on the association between anthracosis and tuberculosis. this study focuses on bronchial anthracosis and associated diseases in the province of south khorasan-iran. methods: this case-series study is performed on patients referred to the vali-e-asre hospital (south khorasan-iran) for bronchoscopic evaluations during the period of 2009-2012. written informed co...
background: genital tuberculosis is a chorionic disease and mostly occurs by haematogenous spread from extra genital source like lungs, peritoneum, lymph nodes and bones. transmission through a sexual intercourse is also possible. since the majority of patients are in reproductive ages, involvement of fallopian tubes and endometrium cause infertility in patients. cases: reviewing 4 cases of fem...
