HEN a stock of Drosophila melanogaster with chromosome 2 marked by wclot, cl, produced brown-eyed flies resembling clot but with the gene in the X chromosome, it was suspected that a translocation had occurred. However, genetic tests, including crosses to a newly acquired yellow prune stock ( y , p n ) showed that a mutation had occurred at the p n locus. The new allele, symbol pn591, is comple...

the main aim of this study was to obtain the crimean-congo hemorrhagic fever virus (cchfv) glycoprotein, through either stable transgenic plants or using a transient expression system, and determine the yield, quality and finally the immunogenicity of the plant-made cchfv glycoprotein in a mouse model. we designed and synthesized a codon-optimized g1/g2 gene from the g1 and g2 parts of the cchf...

Rate coefficients have beenmeasured at 298 K and atmospheric pressure for the reaction of OH radicals and Cl atoms with propylene carbonate. The measurements were performed in a large volume photoreactor using in situ FTIR spectroscopy for the analysis. The following rate coefficients (in units of cm per molecule per s) were obtained: k(OH + PC) 1⁄4 (2.52 0.51) 10 12 and k(Cl + PC) 1⁄4 (1.77 0....

The strategies available for treating salivary gland hypofunction are limited because relatively little is known about the secretion process in humans. An initial microarray screen detected ion transport proteins generally accepted to be critically involved in salivation. We tested for the activity of some of these proteins, as well as for specific cell properties required to support fluid secr...

IN ISOLATED BUNDLES OF EXTERNAL INTERCOSTAL MUSCLE FROM NORMAL GOATS AND GOATS WITH HEREDITARY MYOTONIA THE FOLLOWING WERE DETERMINED: concentrations and unidirectional fluxes of Na(+), K(+), and Cl(-), extracellular volume, water content, fiber geometry, and core-conductor constants. No significant difference between the two groups of preparations was found with respect to distribution of fibe...

Channel-mediated trans-membrane chloride movement is a key process in the active cell volume regulation under osmotic stress in most cells. However, thymocytes were hypothesized to regulate their volume by activating a coupled K-Cl cotransport mechanism. Under the patch-clamp, we found that osmotic swelling activates two types of macroscopic anion conductance with different voltage-dependence a...

purpose: the aim of this study was to test the in vitro sensitivity of lymphocytes of patients with head and neck cancer against gamma irradiation and also to find out if the frequencies of chromosomal aberrations correlate with side effects of radiotherapy. patients and methods : peripheral blood of 101 patients with head and neck cancer was collected before the onset of radiotherapy, cultured...

Cape aloe (Aloe ferox Miller) has been a herb well known for its cathartic properties and has also been used popularly as a health drink (juice, tea and tonic) in the United States and in Europe. Cape aloe extract also has been reported to possess several pharmacological effects, such as anti-inflammatory, anti-bacterial, anti-fungal and protective effect against liver injury. However, the inve...

ABSTRACT Intermediate-mass black holes (IMBHs) could form via runaway merging of massive stars in a young star cluster (YMC). We combine suite numerical simulations YMC formation with semi-analytic model for dynamical friction and evolution central quasi-star, to predict how final quasi-star relic IMBH masses scale properties (and compare observations). The argue that inner density profiles at ...
