A geometric-progression (G-P) method formula, Br = 1 + (B − 1) · (Kx 1)/(K 1), accurately represents the buildup factor data as a function of distance for following reasons:1. The value parameter B corresponds to that at mfp, which is integration basic spectrum specified material and source energy.2. variation K with penetration photon dose multiplication change in shape spectrum.Exposure factors point isotropic sources an infinite medium approximated by G-P fitting parameters are good...

A novel protein with mitogenic activity in vitro and immunomodulating vivo has been isolated from the mycelial extract of an Oriental medicinal fungus, Ling Zhi (Ganoderma lucidium). This was named Zhi-8 (LZ-8) its biochemical immunological properties are described. LZ-8 purified by two chromatographic systems, gel filtration followed ion-exchange, using bioassay measuring blast-formation stimulatory toward mouse spleen lymphocytes to monitor purification. Analysis several types...

Abstract —Angiotensin II (Ang II) is now believed to play a critical role in the pathogenesis of hypertrophy and/or hyperplasia vascular smooth muscle cells (VSMCs). Several G i - and q -coupled receptors, including Ang type 1 (AT ) receptor, activate Rho Rho-associated kinase Swiss 3T3 cardiac myocytes. However, little known about Rho-kinase II–induced VSMCs. In present study, we explored protein synthesis unstimulated cells, RhoA was observed predominantly cytosolic fraction, but it...

8-Anilino-1-naphthalenesulfonic acid (ANS) is used as a hydrophobic fluorescence probe due to its high intensity in environments, and also microenvironment because of unique ability exhibit peak shift change depending on the surrounding solvent environment. The difference can not only be caused by but affected binding affinity, which represented constant (K). However, overall process considering fully understood, requires ANS mechanism examined. In this study, reveal rate-limiting step...

Reactive oxygen species (ROS) have been proposed to mediate vascular hypertrophy induced by angiotensin II (Ang II). Recently, we and others shown that growth-promoting signals Ang involve protein tyrosine kinase (PTK) extracellular signal-regulated (ERK). However, whether ROS contribute the II-induced PTK and/or ERK activation in smooth muscle cells (VSMCs) remains largely unclear. Here, investigated possible involvement of activation. In presence a NADH/NADPH oxidase inhibitor,...

Abstract Dehydroepiandrosterone (DHEA) and its sulfate ester are the most abundant circulating adrenal steroids in humans. Administration of DHEA has been reported to have beneficial effects on obesity, hyperlipidemia, diabetes, atherosclerosis obese rodents, although insulin resistance not fully elucidated. In this study, treatment sensitivity were investigated genetically Zucker rats, an animal model resistance, using euglycemic clamp technique. After 0.4% was administered for 10 days...

Liposomes have been widely used to enhance the immune response. In present investigation, we studied their in vivo immunomodulation of an HIV-1-specific DNA vaccine candidate (pCMV160/REV) constructed with cytomegalovirus (CMV) promoter-conjugated HIV-1 env and rev plasmids. By immunizing pCMV160/REV cationic liposomes through various routes (intramuscular, intraperitoneal, subcutaneous, intradermal, intranasal), induced higher levels both antibody production delayed-type hypersensitivity...

DNA vaccines have the potential of giving rise to a potent cell-mediated immune response by inducing intracellular synthesis and subsequent antigenic presentation encoded antigens. We tested vaccine specific for human immunodeficiency virus type 1 (HIV-1) injection animals with expression plasmids encoding HIV-1 envelope protein Rev regulatory protein. Injection both into mice, rabbits, or macaques was found induce high levels antibodies capable efficiently inhibiting infection...

FtsZ polymerizes into protofilaments to form the Z-ring that acts as a scaffold for accessory proteins during cell division. Structures of have been previously solved, but detailed mechanistic insights are lacking. Here, we determine cryoEM structure single protofilament from Klebsiella pneumoniae (KpFtsZ) in polymerization-preferred conformation. We also develop monobody (Mb) binds KpFtsZ and Escherichia coli without affecting their GTPase activity. Crystal structures FtsZ-Mb complexes...
