The automimmune liver disease primary biliary cirrhosis (PBC) is characterised by serum autoantibodies directed at mitochondrial and nuclear antigens (seen in most patients and a subset of patients, respectively). The antimitochondrial antibodies (AMA) characteristic of PBC are directed at members of the 2-oxoacid dehydrogenase components of multienzyme complexes; in particular, the E2 and E3 b...

The families of 65 patients with systemic sclerosis were examined clinically and serum samples from each subject were tested for antinuclear antibodies (ANA) by immunofluorescence on HEp2 cells and for precipitating antibodies to soluble cellular antigens including Scl-70. Of 217 blood relatives, 58 (27%) had ANA (42 speckled, 13 nucleolar, one centromere, two homogeneous); 22 (10%) had precipi...

BACKGROUND Waddlia chondrophila (W. chondrophila) is an emerging agent of respiratory and reproductive disease in humans and cattle. The organism is a member of the order Chlamydiales, and shares many similarities at the genome level and in growth studies with other well-characterised zoonotic chlamydial agents, such as Chlamydia abortus (C. abortus). The current study investigated the growth c...

Thymoquinone (TQ) and diosgenin (DG), the active ingredients obtained from black cumin (Nigella sativa) and fenugreek (Trigonella foenum graecum), respectively, exert potent bioactivity, including anticancer effects. This study investigated the antineoplastic activity of these agents against squamous cell carcinoma in vitro and sarcoma 180-induced tumors in vivo. TQ and DG inhibited cell prolif...

Cancer is the second leading cause of death worldwide and oxidative stress is one of the factors responsible for causing cancer. Antioxidants play a very important role in prevention of cancer. Therefore, efforts have been made to identify natural antioxidants having anti-cancer potential. Various herbs, fruits and vegetables have diverse phytochemicals that display antioxidant properties and h...

It is well established that interferon-alpha can induce non-cytotoxic intracellular suppression of hepatitis B virus replication, but the mechanisms involved are unclear. Cell culture studies to characterize these mechanisms are restricted, in part because hepatitis B virus replicates almost exclusively in liver-derived cells. To overcome this limitation we used a cytomegalovirus promoter-contr...

During the 18 months January 1975 to June 1976, 25 cases of acute herpetic follicular conjunctivitis and keratoconjunctivitis resembling adenovirus ocular infection presented in the External Eye Disease Clinic, Moorfields Eye Hospital, City Road, London. Herpes simplex virus was isolated in HEp2 cells in 22 patients, and the remaining 3 patients were identified by a minimum 4-fold rise in the l...

AIM The focal theme of present investigation includes isolation of prodigiosin producing fish gut bacteria, enhancing its production using tannery solid waste fleshing, and evaluation of its pharmacological effect. METHODS Optimization of fermentation conditions to yield maximum prodigiosin, and instrumental analysis using FTIR, NMR, ESI-MS, TGA, and DSC. RESULTS The optimum conditions requ...

Human Respiratory Syncytial Virus (HRSV) is a leading cause of bronchopneumonia in infants and the elderly. To date, knowledge of viral and host protein interactions within HRSV is limited and are critical areas of research. Here, we show that HRSV Matrix (M) protein interacts with the cellular adaptor protein complex 3 specifically via its medium subunit (AP-3Mu3A). This novel protein-protein ...
