Oxytocin has a fundamental role in social behavior. In humans, supporting evidence shows that oxytocin enhances people's ability to trust or affiliate with others. A key question is whether differences in plasma oxytocin concentration in humans are related to people's differences in their social traits of personality and if such differences are reflected in the structural organization of brain ...
Two new species of lizards assigned to the genus Euspondylus from the montane forests of the Peruvian Andes in the Pasco Department (central Peru) and Ayacucho Department (southern Peru) both at elevations of 2550 and 3450 m, respectively, are described. The new species are distinguishable from all other Peruvian and Ecuadorian species of Euspondylus by a unique combination of morphometric, sca...
Taxonomic markers (head structure morphometry, isoenzymes and randon amplified polymorphism of DNA - RAPD) were used to understand the population dynamics of Triatoma vitticeps, predominant triatomine species in Itanhomi district, using samples obtained from domestic, peridomiciliary and sylvatic habitats. Morphometric analysis revealed sexual dimorphism within the three samples although specim...
Help seeking (HS) is a core coping strategy that is directed towards obtaining support, advice, or assistance as means of managing stress. Women have been found to use more HS than men. Neural correlates of sex differences have also been reported in prefrontal-limbic system (PLS) regions that are linked to stress and coping, yet structural differences between men and women relating to HS in the...
BACKGROUND Digital image analysis has an important role in geographical provenance of grains, as it can provide parameters of size, shape and color, which are important quality parameters for the design of engineering processes such as drying and milling of grains. In this study, digital image analysis was used to classify nine rice cultivars based on different morphometric parameters using the...
This study determined association of some morphometric characteristics of udder with mastitis in dairy cattle. For this purpose; 100 animals each negative and positive for mastitis by California Mastitis Test and bacteriology, were selected from amongst those brought for slaughter at Faisalabad abattoir. Morphometric observations on udder were recorded pre-slaughter; whereas, samples from mamma...
The analysis of drainage morphometry is usually a prerequisite to the assessment of hydrological characteristics of surface water basin. In this study, the western region of the Arabian Peninsula was selected for detailed morphometric analysis. In this region, there are a large number of drainage systems that are originated from the mountain chains of the Arabian Shield to the east and outlet i...
BACKGROUND Oral submucous fibrosis (OSMF) is a chronic oral mucosal disease characterized by progressive deposition of collagen in subepithelial connective tissue and epithelial atrophy. The present study was conducted to evaluate the changes in epithelial thickness and cellular and nuclear morphometric characteristics of parabasal and spinous compartments of the epithelium in various stages of...
An immunohistochemical and morphometric analysis was performed on trephine biopsy specimens of the bone marrow in 40 patients (23 men and 17 women, mean age 62 years) with different subtypes of myelodysplastic syndromes (MDS) to determine dysmegakaryopoiesis, but particularly precursor cells--that is, pro- and megakaryoblasts. In 31 of the 40 patients the numbers of megakaryocytes were increase...
To investigate the influence of the pineal gland through melatonin secretion on the physiological and morphological parameters of pancreatic islets, we studied the plasma biochemistry and morphological and morphometric characteristics of the endocrine pancreas of male Wistar rats. The animals were distributed into five groups of ten rats each: NC - normal control group; NS -- sham-operated grou...
