This study was designed to determine whether cholinergic receptors are operative in the coronary vessels of a hibernating species (golden mantled ground squirrel, Spermophilus lateralis) and a nonhibernating species (rat, Rattus norvegicus) under normothermic and hypothermic conditions. Coronary flow and left ventricular systolic pressure were measured in isolated perfused hearts from squirrels...

In many regions of the mammalian cerebral cortex, cells that share a common receptive field property are grouped into columns. Despite intensive study, the function of the cortical column remains unknown. In the squirrel monkey, the expression of ocular dominance columns is variable, with columns present in some animals and not in others. By searching for differences between animals with and wi...

The reporting of pain was compared for U.K. Persian Gulf War veterans, veterans from the Bosnian conflict, and personnel employed in the military at the time of the Persian Gulf War but not deployed (era comparison group). Pain manikins were used to assess the prevalence of the reporting of pain in different body sites and the prevalence of the reporting of widespread pain, in relation to compa...

OBJECTIVE The most commonly used instrument for the research and treatment of excessive internet use is Young's Internet Addiction Test (IAT). While the IAT has been translated to several languages (including Persian) and has demonstrated good psychometric properties across several independent studies, there is still a room for alternative assessment instruments. This study reports a validation...

The Indo-Persian state secretary has occupied center stage in the emerging discourse on bureaucracy, administration and the political formation of the Mughal state. The status and role of the munsh? (the IndoPersian state secretary) within the Mughal bureaucratic structure in 17th and 18th century have formed the basis of recent historical analysis. Scholarship on the Indo-Persian munsh? have b...

Finding an appropriate dataset for natural language processing applications is one of the main challenges for researches of this field. This issue is more problematic in Non-Latin languages especially Persian language. Access to an appropriate dataset that can be used in development of practical programs in language processing field, helps us to validate the obtained results and provide the fea...

BACKGROUND Measuring the impacts of oral conditions on quality of life is an important part of oral health needs assessment. For this purpose a variety of oral health-related quality of life instruments have been developed. To use a scale in a new context or with a different groups of people, it is necessary to re-establish its psychometric properties. The objectives of this study are to develo...

In order to enhance our understanding of the evolutionary history of squirrel monkeys (Saimiri spp.), we newly sequenced and analyzed data from seven complete mitochondrial genomes representing six squirrel monkey taxa. While previous studies have lent insights into the taxonomy and phylogeny of the genus, phylogenetic relationships and divergence date estimates among major squirrel monkey clad...

PURPOSE To evaluate and characterize the New-World squirrel monkey as a primate model for experimental choroidal neovascularization (CNV) studies and to compare it with the current Old-World macaque monkey model. METHODS Fibrovascular tissues (FVT) were elicited in 12 maculae of seven squirrel monkeys by laser photocoagulation using optimized laser parameters (532 nm, 0.05 second, 75 micro m,...

Pancreatic triacylglycerol lipase (PTL) is expressed in novel locations during hibernation in the thirteen-lined ground squirrel (Spermophilus tridecemlineatus). PTL cDNAs isolated from two of these locations, heart and white adipose tissue (WAT), contain divergent 5'-untranslated regions (5'-UTRs) suggesting alternative promoter usage or the possibility of multiple PTL genes in the ground squi...
