Activation of the classical complement pathway on the membrane of autologous cells results in the deposition of C4b on their surface and in the assembly of the C3 convertase C4b2a, one of the amplifying enzymes of the cascade. Here we study the sequence of events leading to irreversible inactivation of the potentially harmful C4b bound to human red cells. We show that deposited C4b interacts en...

BACKGROUND Red-skin root disease has seriously decreased the quality and production of Panax ginseng (ginseng). METHODS To explore the disease's origin, comparative analysis was performed in different parts of the plant, particularly the epidermis, cortex, and/or fibrous roots of 5-yr-old healthy and diseased red-skin ginseng. The inorganic element composition, phenolic compound concentration...

Vatanparast M., Hosseininaveh V., Ghadamyari M., Minoo Sajjadian S. (2014): Plant cell wall degrading enzymes, pectinase and cellulase, in the digestive system of the red palm weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae). Plant Protect. Sci., 50: 190–198. In digestion, the red palm weevil, Rhynchophorus ferrugineus, has been adapted to overcome the plant cell wall barrier, spec...

OBJECTIVE To find out host gene expression profiles after malarial infection. METHODS Further time-course microarray analysis of peripheral blood mononuclear cells focusing on malaria pathogenesis was performed. RESULTS Up-regulation of coagulation-related genes, heat shock proteins, glycolytic enzymes, glucose transporters, and vacuolar H(+)-ATPases was found in acute febrile malaria. In e...

ATP stimulates Na transport into inside-out vesicles (IOVs) made from human red cell membranes; strophanthidin inhibits the ATP-stimulated transport. The substrates for glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoglycerate kinase (PGK) (glycolytic enzymes bound to the cytoplasmic surface of the red cell membrane) also stimulate Na transport into IOVs without added ATP. The eluti...

Introduction: Musculoskeletal growth is variable during adolescent period and reaches its maximum by 18 years, whereas hemopoietic parameters reach adult values by 15 years. After adolescence period, the blood parameters may vary with nutrition and built of the individual. The purpose of this study was to find out any correlation between anthropometric and hematological parameters after the ado...
