rodent ectoparasites seems have a main role in transmission of some zoonotic pathogens from commensal rats to human and pets such as leishmaniasis, plague, cchf, etc. so rodents as the main reservoirs, are potential health dangers in human communities. the aim of this study was to determine the prevalence and frequency of identified ectoparasites in north of tehran . rodents were captured with ...

Voluntary muscle force control is accomplished both by recruitment of motor units (MUs) and by firing rate modulation of active MUs. Typically, MU recruitment and firing rate organization is assessed using piecemeal intramuscular recordings drawn from different experiments, or even from different subjects. As a consequence, it is often difficult to assemble a systematic description of the relat...

OBJECTIVE The Somatic Signal Detection Task (SSDT; Lloyd, Manson, Brown and Poliakoff, 2008) is an innovative paradigm to study perceptual processes related to physical symptoms. It allows examining touch illusions as a laboratory analog of medically unexplained symptoms (MUS) according to the cognitive model of MUS proposed by Brown (2004). The present study compared psychopathologic measures ...

Slow motor units (MUs) have no sag in their unfused tetani. This study in anesthetized rats shows that the sag can be observed in slow soleus MUs after prolonged activity. Twitches and unfused tetanic contractions were recorded from male (n=35) and female (n=39) MUs before and after the four minutes of the fatigue test (trains of 13 pulses at 40 Hz repeated every second). After this activity tw...

Methods for analyzing infeasible constraint sets have proliferated in the past decade, commonly focused on finding maximal satisfiable subsets (MSSes) or minimal unsatisfiable subsets (MUSes). Most common are methods for producing a single such subset (one MSS or one MUS), while a few algorithms have been presented for enumerating all of the interesting subsets of a constraint set. In the case ...

OBJECTIVE To compare the efficacy and safety in a contemporary cohort of women who were offered either a pubovaginal sling (PVS) or a synthetic midurethral sling (MUS) after the U.S. Food and Drug Administration notification and made an informed decision on procedure option. METHODS A total of 201 women were given the option between a PVS and an MUS. Prior anti-incontinence surgery and concom...

Introduction Transcranial magnetic stimulation (TMS) is widely used to explore cortical physiology in health and disease. Surface electromyography (sEMG) appropriate for superficial muscles, but cannot be applied easily less accessible muscles. Muscle ultrasound (mUS) may provide an elegant solution this problem, fundamental questions remain. We the relationship between TMS evoked muscle potent...

Multiple Sclerosis (MuS) is a disease caused due to an autoimmune attack against myelin components in which non proteic mediators may play a role. Recent research in metabolomics and lipidomics has been driven by rapid advances in technologies such as mass spectrometry and computational methods. They can be used to study multifactorial disorders like MuS, highlighting the effects of disease on ...

Respiratory muscle weakness is common in children with neuromuscular disease (NMD). We hypothesized that weakness puts them at risk for respiratory muscle fatigue, a harbinger of chronic respiratory failure. We therefore measured a noninvasive index of respiratory muscle fatigue, the tension-time index of the respiratory muscles (TT(mus)), in 11 children with NMD and 13 control subjects. Spirom...

In monogamous mound-building mice Mus spicilegus, facultative polygyny was observed in April, at the beginning of the reproductive season. In order to evaluate the cost of polygyny, we compared, under laboratory conditions, the reproductive success of trios and pairs composed of sister females mated with unrelated brother males. Females in trios were able to tolerate each other during the repro...
