an experiment was conducted to study the effect of epinephrine (ep) and bromocriptine (br) on productive traits of laying hens. thirty white leghorn hens, 50 weeks old, were divided into three equal treatments (with 10 hens for each treatment): control, physiological serum (0.5 ml/hen/week), ep (0.5 ml/hen/week) and br (100 g/kg of body weight (bw); w/v in absolute alcohol). hens were injected ...

BACKGROUND Toll-like receptor 4 (TLR4) is a crucial receptor in the innate immune system and noninfectious immune responses. It has been reported that TLR4 participates in the pathological course of ischemia/reperfusion (I/R) injury. However, the role of TLR4 in the process of I/R injury after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) is still unknown. In this study, we invest...

The energy landscape of helium-nitrogen mixtures is explored by ab initio evolutionary searches, which predicted several stable compounds in the pressure range from 25 to 100 GPa. In particular, monoclinic structure HeN$_{22}$ consists neutral He atoms, partially ionic dimers N$_{2}$$^{\delta-}$, and lantern-like cages N$_{20}$$^{\delta+}$. presence helium not only greatly enhances structural d...

Intravenous injection of toxic doses of Chlamydia psittaci elementary bodies into endotoxin-responsive C3H/HeN mice or endotoxin-nonresponsive C3H/HeJ mice resulted in essentially identical time intervals to death. Inoculation of monolayer cultures of thioglycolate-stimulated peritoneal macrophages from the two strains of mice with 250 elementary bodies per macrophage resulted in immediate host...

Triaxial deformations are considered for determining the binding energies of open-shell, unpolarized HeN clusters. The shapes of He clusters are found to be close to spherical, in contrast to the well-deformed shapes of alkali-metal clusters. As a result, odd-even alternations and subshell closures between major shells are absent in the size evolution of the chemical potentials, and the second-...

The susceptibilities of C3H/HeN, BALB/c, and C57BL/6N mouse strains to group B streptococci (GBS) infection were evaluated. C3H/HeN mice developed severe polyarthitis; mild lesions and no lesions were observed in BALB/c and C57BL/6N mice, respectively. A correlation between the severity of arthritis, the number of GBS in the joints, and local interleukin-6 and interleukin-1beta production was e...

HenPower is a programme that enables older people who live with dementia in care homes to take part hen-keeping and hen-related creative activities. It was introduced into UK address evidence suggesting adults can experience diminished personal wellbeing. This study aimed 1) assess the impact of on have are living home 2) explore staff views experiences programme. A nested qualitative design ad...

In recent papers, Tanabe et al.(1956,1957) reported that no increase in the uptake of I131 by the thyroid was observed in molting hens as compared with laying hens,and no acceleration in the release of I131 as thyroid hormone from the thyroid of the hen was observed either in molting period or in pre-molting period. Further-more, it has been shown that thiouracil feeding does not prevent natura...

Environmental conditions and bird health are important elements in assessment of animal welfare for laying hen housing systems, but limited information is available comparing different types of systems. Three types of laying hen houses caged high-rise, caged manure-belt, and cage-free floor-raised were monitored for temperature, relative humidity, carbon dioxide, and atmospheric ammonia during ...
