Extracellular polymeric substances (EPS) play important roles in regulating the dewaterability of sludge. This study sought to elucidate the influence of EPS on the dewaterability of sludge during bioleaching process. Results showed that, in bioleaching system with the co-inoculation of Acidithiobacillus thiooxidans TS6 and Acidithiobacillus ferrooxidans LX5 (A. t+A. f system), the capillary su...

BACKGROUND/AIMS Spinal tuberculosis (TB) is a common and dangerous form of extrapulmonary TB with unclear mechanisms in its occurrence and progression. This study investigated the clinical significances of bone morphogenetic protein-4 (BMP-4), osteopontin (OPN), and vitamin D receptor (VDR) gene polymorphism, mRNA and protein expression in spinal TB patients. METHODS BMP-4 and OPN gene polymo...

BACKGROUND/AIMS Osteopontin (OPN) expression is increased during the course of various chronic inflammatory diseases, including tuberculosis (TB). However, its prognostic value in TB management remains unclear. This study aimed to determine whether OPN could associate with other cytokines serving as a reliable biomarker for evaluating the effectiveness of early anti-TB treatments. METHODS Sme...

BACKGROUND Tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) remains a poorly understood complication in HIV-TB co-infected patients initiating antiretroviral therapy (ART). The role of the innate immune system in TB-IRIS is becoming increasingly apparent, however the potential involvement in TB-IRIS of a leaky gut and proteins that interfere with TLR stimulation by ...

Background: Tuberculosis (TB) is a major cause of death worldwide. Finding an effective vaccine against TB is the best way to control it. Several vaccines against this disease have been developed but none are completely protective. The aim of this study was to design and construct a cloning vector containing the Mycobacterium tuberculosis (M. tuberculosis) heat shock protein X (hspX). Metho...

Belalang kembara merupakan hama yang sangat merugikan pertanian pada beberapa kabupaten di NTT setiap tahunnya. Pengendalian belalang melalui pemanfaatan potensi pangan serangga ini dapat menjadi solusi ekonomis bagi masyarakat. diketahui salah satu sumber kaya protein. Konsumsi dalam bentuk produk olahan seperti nugget introduksi awal belalang. Penelitian pengembangan dilakukan dengan 5 perlak...

BACKGROUND The identification of antigens able to differentiate tuberculosis (TB) disease from TB infection would be valuable. Cellular and humoral immune responses to Erp (Exported repetitive protein)--a recently identified M. tuberculosis protein--have not yet been investigated in humans and may contribute to this aim. METHODS We analyzed the cellular and humoral immune responses to Erp, ES...

Recent developments in genetic engineering allow the employment of plants as factories for 1/foreign protein production. Thus, tuberculosis (TB) ESAT6 antigen was expressed in different plant systems, but the level of vaccine protein accumulation was extremely low. We describe the technology for superexpression of TB vaccine proteins (Ag85B, ESAT6, and ESAT6:Ag85B fusion) in plant leaves which ...
