objective: neuroimmune factors contribute on the pathogenesis of sickness behaviors. nigella sativa (ns) has anti-inflammatory, anti-anxiety and anti-depressive effects. in the present study, the effect of ns hydro-alcoholic extract on sickness behavior induced by lipopolysaccharide (lps) was investigated. materials and methods: the rats were divided into five groups (n=10 in each): (1) control...

Exercise-induced muscle fatigue has been shown to be the consequence of peripheral factors that impair muscle fiber contractile mechanisms. Central factors arising within the central nervous system have also been hypothesized to induce muscle fatigue, but no direct empirical evidence that is causally associated to reduction of muscle force-generating capability has yet been reported. We develop...

BACKGROUND The introduction of antiretroviral therapy (ART) has dramatically reduced the mortality rate of people living with HIV (PLHIV). However, complications of both HIV and ART, such as peripheral neuropathy currently affect PLHIV. The purpose of this study was to establish the prevalence of peripheral neuropathy of the lower extremity and, its association with demographic and health statu...

Peripheral vascular disease (PVD) has numerous modifiable risk factors. This study aimed to establish patients' awareness of risk factors and causes of PVD and their understanding of mechanisms of secondary prevention. A prospective survey of awareness of PVD among patients attending a tertiary vascular clinic for management of peripheral vascular disease was undertaken. Institutional review bo...

Introduction The modifications induced by an eccentric training can be attributed to both peripheral factors (e.g. contractile changes) and/or central factors (e.g. neural adaptations) (Colson et al. 1999). The peripheral changes could be essentially expressed by a selective adaptation of the fast twitch motor units, which are preferentially solicited during eccentric actions. The central facto...

normal 0 false false false en-us x-none ar-sa background: diabetes mellitus (dm) is a common metabolic disorder that can cause various complications including, peripheral neuropathy (pnp). some possible risk-factors such as blood glucose level, hyperglycemia, duration of diabetes, and lipid profiles are assumed to be important in diabetic pnp incidence. the aim of this study is to evaluate the ...

The sense of equilibrium is influenced by various factors of visual stimulation, especially far peripheral vision and a motion parallax. An investigation of these two factors was made in order to apply the findings to construct a rehabilitation method for equilibrium disorders. From the experimental results, it was found that the center of gravity for the subjects was greatly affected by both f...

The etiology of Parkinson's disease (PD) is complex and most likely involves numerous environmental and heritable risk factors. Recent studies establish that central and peripheral inflammation occurs in the prodromal stage of the disease and sustains disease progression. Aging, heritable risk factors, or environmental exposures may contribute to the initiation of central or peripheral inflamma...

background : mdm2, e-cadherin, survivin and her2 genes are involved in the regulation of normal cell growth. however, any crucial change in their expression levels can convert a normal cell into a cancer cell. numerous studies have identified alterations of these gene expression levels in various cancers, particularly in breast cancer. thus, they may be used as diagnostic biomarkers. in this ex...
