Genome packaging is functionally coupled to replication in RNA viruses pathogenic to humans (Poliovirus), insects (Flock house virus [FHV]), and plants (Brome mosaic virus [BMV]). However, the underlying mechanism is not fully understood. We have observed previously that in FHV and BMV, unlike ectopically expressed capsid protein (CP), packaging specificity results from RNA encapsidation by CP ...

Background: Inflammation and infectious agents such as Chlamydia pneumoniae have been associated with cardiovascular disease. Objective: To evaluate the serum high sensitivity C - reactive protein (hs-CRP) and antibodies against Chlamydia pneumoniae and Chlamydial heat shock protein-60 (Cp-HSP60) in patients with ischemic heart disease (IHD). Methods: 62 patients with IHD having either acute my...

This experiment investigated the effect of dietary crude protein (CP) and ruminally degraded protein (RDP) levels on rumen fermentation, digestibility, ammonia emission from manure, and performance of lactating dairy cows. The experiment was a replicated 3 x 3 Latin square design with 6 cows. Three diets varying in CP concentration were tested (CP, % of dry matter): 15.4 (high CP, control), 13....

The first detailed report of a specific interaction of CP (caeruloplasmin) with another protein described its complex with LF (lactoferrin) in 2000. Since then, several protein-protein interactions involving CP have been reported, mostly concerning iron-containing proteins. The CP-LF complex was studied thoroughly, and evidence of reciprocal effects of CP and LF was obtained. Another specific i...

The present study was conducted to investigate the effects of crude protein (CP) content starter feed and wheat straw (WS) processing on growth performance, digestibility, ruminal fermentation, behavior Holstein calves. Sixty calves (28 male 32 female) were randomly assigned 1 4 treatments in a randomized complete block design. Treatments 2 × factorial arrangement (1) lower-CP ground mixed with...

Spectroelectrochemical studies of the intervalence charge transfer (IVCT) characteristics of both diastereoisomeric forms of the dinuclear complex [{Ru(bpy)2}2(mu-dpi-)]n+ [bpy=2,2'-bipyridine; dpi-=4,5-di(2-pyridyl)imidazolate] showed that the degree of inter-metal electronic coupling (or valence delocalization) is dependent on stereochemical identity. Increasing the relative concentration of ...

Capping protein (CP) has critical roles in actin assembly in vivo and in vitro. CP binds with high affinity to the barbed end of actin filaments, blocking the addition and loss of actin subunits. Heretofore, models for actin assembly in cells generally assumed that CP is constitutively active, diffusing freely to find and cap barbed ends. However, CP can be regulated by binding of the 'capping ...

The response of laying Japanese quails to dietary levels of energy and protein on performance, egg quality, hatchability, fertility and their effect on subsequent offspring live body weight was investigated. A total of 432 Japanese quails (13 weeks old) were divided into nine treatments. Each treatment comprised of four replicates of twelve birds (9 females and 3 males). Nine diets including th...

petroleum hydrocarbons are important energy resources used by industry and in our daily life, whose production contributes highly to environmental pollution. to control such risk, bioremediation constitutes an environmentally friendly alternative technology that has been established and applied. it constitutes the primary mechanism for the elimination of hydrocarbons from contaminated sites by ...
