The purpose of this study was to characterize the hepatobiliary disposition of timosaponin B2 (TB-2), a natural saponin. Although TB-2 has multiple pharmacologic activities, the mechanism of its hepatobiliary disposition has not been explored. Because the metabolism of TB-2 is limited and the accumulation of TB-2 in primary hepatocytes is highly temperature dependent (93% of its accumulation is...

Đặt vấn đề: Interleukin-2 (IL-2) đang được quan tâm trong điều trị ung thư và các bệnh tự miễn. Tuy nhiên, ở Việt Nam, nguồn IL-2 dùng cho thử nghiệm in vitro có giá thành cao. Mục đích: tạo người tái tổ hợp dạng dung với tag SUMO trên Escherichia coli. Phương pháp: Tạo dòng chủng E. coli BL21(DE3) mang plasmid pET-SUMO-il2 khả năng biểu hiện SUMO. Khảo sát kiện nuôi cấy để thu protein tan: môi...

Several susceptibility-associated genetic polymorphisms have been proposed to explain differential susceptibility to tuberculosis (TB) disease progression in different populations. Here, polymorphisms in the natural resistance-associated macrophage protein 1 (NRAMP1), vitamin D receptor, tumor necrosis factor-alpha, interleukin (IL)-1, and IL-10 genes were evaluated in 358 Cambodian patients wi...

Exogenous insulin treatment has been shown to improve food intake and host weight of cachectic tumor-bearing (TB) rats, but the composition of the host weight gain has not been quantitated. Sixty-six Fischer 344 rats were randomized to seven groups: early nontumor-bearing (NTB) (n = 10) who underwent compositional analysis (CA) on the day the methylcholanthrene sarcoma was implanted in TB rats;...

BACKGROUND Diagnosis of childhood tuberculosis (TB) is difficult in high TB burden settings. Interferon-gamma-induced protein 10 (IP10) has been suggested as a marker of TB infection and disease, but its ability to differentiate the two conditions remains uncertain. OBJECTIVES To describe Interferon-gamma (INFγ) and IP10 expression in children with TB infection and disease and controls to ass...

To understand the key determinants in calcium-binding affinity, a calcium-binding site with pentagonal bipyramid geometry was designed into a non-calcium-binding protein, domain 1 of CD2. This metal-binding protein has five mutations with a net charge in the coordination sphere of -5 and is termed DEEEE. Fluorescence resonance energy transfer was used to determine the metal-binding affinity of ...

Tuberculosis is a chronic infectious disease that attacks the lung parenchyma. Pulmonary TB caused by bacterium Mycobacterium tuberculosis. classified into and Extra TB. The prevalence of globally 10 million people; Indonesia ranks second after China India. This study aims to determine relationship between levels C-Reactive Protein (CRP) with number lymphocytes in patients pulmonary at BKPM Pur...

In cancer and chronic infectious diseases, immune checkpoint-blockade of inhibitory receptors can enhance T-cell immunity. In tuberculosis (TB), a chronic infectious disease, prolonged antigen exposure can potentially drive terminal T-cell differentiation towards functional 'exhaustion': in human TB T-cells express PD-1 (programmed cell death protein-1) and CTLA-4 (cytotoxic T-lymphocyte-associ...

BACKGROUND Tuberculosis (TB) is one of the world's deadliest diseases, and one-third of the world's population is infected with it. The link between antitumor necrosis factor therapy and reactivation of latent TB is well recognized. However, only limited studies have evaluated the risk of TB with rituximab, a B-cell-targeting therapeutic agent used recently for rheumatological diseases, primari...
