The class I and class II major histocompatibility complex (MHC) antigens are polymorphic cell-surface glycoproteins that present antigenic peptides to T lymphocytes in the generation of immune responses. While much is known about the recognition and processing of antigens, the nature of T-cell recognition sites on MHC molecules is poorly understood. Both structural and functional studies have s...

Interleukin-6 (IL-6), a central proinflammatory cytokine, maintains immune homeostasis and also plays important roles in cervical cancer. Therefore, we aimed to evaluate any associations of IL-6 gene polymorphisms at positions -174 and -572 with predisposition to cervical cancer in a Chinese population. The present hospital- based case-control study comprised 518 patients with cervical cancer a...

In a structural model of the 2-kinase domain of the bifunctional enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase based on the analogy with adenylate kinase, Lys-174, Asp-179 and Asp-191 residues are located in the putative active site. Asp-179 and Asp-191 are conserved in all known 6-phosphofructo-2-kinase sequences. In contrast, Lys-174 is conserved except in a yeast isoenzyme, fbp...

BACKGROUND Interleukin-4 (IL-4) and interleukin-6 (IL-6) have been reported to associate with pathogenesis of rheumatoid arthritis (RA); however, the role of IL-4 and IL-6 genetic polymorphisms in RA remains unknown. METHOD A total of 752 unrelated Chinese patients with RA and 798 healthy Chinese volunteers with no family histories of any autoimmune diseases were recruited. The promoter IL-4-...

UNLABELLED ABSTRACT Purpose: Knowledge about the role of inflammation in the pathogenesis of arrhythmias in children is limited. Several studies have suggested a relationship between plasma IL-6 levels and/or the -174G>C IL-6 gene polymorphism and atrial fibrillation in adults. Our present study was performed to investigate whether serum IL-6, -174G>C IL-6 polymorphism and C-reactive protein (C...

C M P0 4 The arrowed objects are tyrosine crystals. Tyrosine crystals are rare and their presence in urine is always abnormal. They form clusters of silky needle-like structures that are colorless, or black on focusing. Tyrosine crystals are found in acid urine, increase after refrigeration, and are insoluble in alcohol or ether. They are soluble in dilute hydrochloric acid, alkali and relative...
