Spontaneous histamine release from isolarted Mastcells was found to be independent of cal­cium in the concentration range up to 1 m. mole/lit. Phosphatidyl serine do not change the effect of calcium on spontaneous release. The activation of anaphyla.ctic histamine release by calcium is potentiated by phosphatidyl serine but the laitter can't do so w1th strontium.  Mastcells, pretreated with AT...

Abstract Cancer cells optimize nutrient utilization to supply energetic and biosynthetic pathways. This metabolic process also includes redox maintenance epigenetic regulation through nucleic acid protein methylation, which enhance tumorigenicity clinical resistance. However, less is known about how cancer exhibit flexibility sustain cell growth survival from low microenvironment. Here, we find...

ABSTRACTBackground: This study aimed to present a rare case of Neu-Laxova syndrome (NLS) and review the newly revealed genetic features of the disease in hopes to find a way for early interventions.Case report: Female newborn with NLS was born at 30 weeks of gestation to consanguineous parents. The last prenatal ultrasound imaging revealed severe intrauterine growth restriction and microcephaly...

in this paper, the hydrogen bonding (hb) effects on the nmr chemical shifts of selected atoms in serineand serine-nh2o complexes (from one to ten water molecules) have been investigated with quantummechanical calculations of the 15n and 13c tensors. interaction with water molecules causes importantchanges in geometry and electronic structure of serine.for the compound studied, the most importan...

one of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. the four pattern recognition molecules that have been identified till now are mannose binding lectin (mbl), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. mbl ...
