Integrins are transmembrane receptors composed ofa andb subunits that mediate bidirectional signaling between the extracellular matrix and the cell interior. Among the best studied integrins is aIIbb3, which is required for hemostasis and platelet involvement in thrombosis. The related b3 integrin, aVb3, is expressed at low levels in platelets and better expressed in several other hematopoietic...

The accumulation of proline impacts the defense mechanisms plants against harmful effects adverse environmental conditions; however, its concentration in is associated with metabolism N. Therefore, exogenous organic [glutamate (Glu)/arginine (Arg)] and inorganic [nitrate (NO3−)/ammonium (NH4+)] N on (Pro) rice under trivalent chromium [Cr(III)] stress were studied through using mass balance mat...

Sustained infection of HeLa cells by Coxsackie B3 virus, dependent on presence of viral inhibitor in culture medium, was achieved. Persistent treatment of carrier cultures with anti-Coxsackie B3 hyperimmune monkey serum eventually eliminated virus from carrier cultures indicating that a lysogenic virus-cell relationship was not operative. Free virus was produced continuously by carrier cultures...

high molecular weight (hmw) glutenin sub-units and baking quality related traits were studied in 49 iranian wheat landraces. the protein content ranged from 11.2% to 13.55%, and sds sedimentation volume varied between 40 and 60 milliliters. high molecular weight glutenin electrophoresis profiles revealed that at the glu-a1 locus, the frequency of null allele was higher than sub-units 1 and 2*. ...

Osteoarthritis (OA) is a common disease in the elderly due to an imbalance in cartilage degradation and synthesis. Heterotopic ossification (HO) occurs when ectopic masses of endochondral bone form within the soft tissues around the joints and is triggered by inflammation of the soft tissues. Procyanidin B3 (B3) is a procyanidin dimer that is widely studied due to its high abundance in the huma...

The bed nucleus of the stria terminalis (BST) is known to contain estrogen (E)- concentrating neurons. In addition, injections of E into BST have been reported to potentiate the sympathoinhibitory arterial pressure (AP) and heart rate (HR) responses elicited by glutamate (Glu) stimulation. In this study, the effect of GABA-A antagonist receptors, bicuculline methiodide (BMI), in the rostral ven...

Eph receptor tyrosine kinases are involved in nervous system development. Eph ligands, termed ephrins, are transmembrane proteins that bind to Eph receptors, the mutual activation of which causes repulsive effects in reciprocally contacting cells. Previously, we showed that overexpression of EphB2 in glioma cells increases cell invasion. Here, expression profiles of ephrin-B family members were...

In the seed, a fundamental transition between embryo and vegetative phases of plant development is coordinated by the interaction between the AFL and VAL sub-clades of the plant specific B3 domain transcription factor family. The AFL B3 factors together with LEC1-type HAP3 transcription factors promote embryo maturation; whereas the VAL B3 factors repress the LEC1/AFL (LAFL) network during seed...

enteroviruses are the causative agents of a number of diseases in humans. group b coxsackieviruses are believed to be the most common viral agents responsible for human heart disease. genomic data of enteroviruses has allowed developing new molecular approaches such as nucleic acid sequence based amplification (nasba) for detection of such viruses. in this study, coxsackievirus b3 (cvb3) was de...
