| Abstract The aim of the present research was to propose a bioclimatic mapping to classify the thermal comfort and discomfort of rural workers within the state of Minas Gerais, considering historical and future scenarios. Monthly historical series (1976-2014) of minimum, mean and maximum temperature-humidity index (THI), determined through the values of air temperature (minimum, mean and maximum) and relative humidity from 48 weather stations located in the state of Minas Gerais were used to analyze the trends through Mann-Kendall and linear regression assays. The bioclimatic mapping of human comfort, obtained via geostatistical analysis, was developed as a function of the minimum, medium and maximum THI for the historical period (1976-2014) and future... |

| Abstract Polyploidy does not usually occur in germinal cells of mammals and other higher vertebrates. We describe a unique example of mosaic autotetraploidy in the meiosis of a human male. Although the original observations were made in the late 1960s, we did not publish them at that time, because we expected to detect further examples that could be described together. However, this did not occur and we have now decided to make the observations available to demonstrate that polyploidy in mammalian male meiosis can arise at a higher frequency than expected by random polyploidization of individual meiotic cells, by either DNA duplication or cell fusion prior to synapsis. This is the first description of a population of primary spermatocytes exhibiting... |

| Pollution of the environment by human and animal faecal pollution affects the safety of shellfish, drinking water and recreational beaches. To pinpoint the origin of contaminations, it is essential to define the differences between human microbiota and that of farm animals. A strategy based on real-time quantitative PCR (qPCR) assays was therefore developed and applied to compare the composition of intestinal microbiota of these two groups. Primers were designed to quantify the 16S rRNA gene from dominant and subdominant bacterial groups. TaqMan((R)) probes were defined for the qPCR technique used for dominant microbiota. Human faecal microbiota was compared with that of farm animals using faecal samples collected from rabbits, goats, horses, pigs, sheep... |

| Screening of a flounder ovary cDNA library with a rainbow trout p53 probe led to the isolation of a p53-unrelated cDNA encoding an unknown 161 amino acid protein. In view of its apparent molecular weight and yet unknown function, the deduced protein was named Xp18. Corresponding orthologous cDNAs or expressed sequence tags have been identified in several species including human, rodents, bovine, chicken and zebrafish and a related cDNA has also been isolated in the fruit fly. Deduced amino acid sequences appeared to be extremely well conserved throughout vertebrate evolution. Structure predictions suggested that Xp 18 may correspond to an integral protein comprising four transmembrane domains. The charged C-termini of all known vertebrate Xp18-like... |

| The purpose of the present study was to compare the platelet and fibrin network ultrastructure of humans to eight different animal species in order to determine the differences between human and animal platelet and fibrin morphology, and to determine whether the animals studied differ in their platelet and fibrin morphology, and whether these differences can be observed by scanning electron microscopy. Platelets and fibrin networks play an important role both in the coagulation process as well as physiologically in allergic processes and immunological mechanisms. The thickness of human fibrin networks were compared to mouse (Mus musculus), equine (Equus caballus), vervet monkey (Chlorocebus aethiops previously Cercopithecus aethiops), oryx (Oryx gazella),... |

| Inadequate ossification of the interparietal region induces the appearance of interparietal and wormian bones, also associated with genetic factors. The formation of the interparietal bone depends on the separation of the intermediate segment from the lateral plate by the transverse occipital suture, which means that this bone is formed by the medial and lateral plates. Wormian interparietal bones or epactal bones are located within the interparietal region, being single or multiple, and are located in the upper central region of the interparietal region, the sutural bones, however, are formed from additional ossification centers that can occur in near sutures. The aim of this work was to macroscopically evaluated the presence of changes in the structure... |

| Morphometric parameters of olfactory brain components show species-dependent variations. However, the association of these parameters with olfactory function vis-à-vis ecological and evolutionary behaviors is poorly understood. In this study, a morphometric analysis of the olfactory bulb, tract and stria was carried out in three ecologically diverse animals comprising humans (primate), dogs (carnivore) and goats (herbivore) to elucidate differences in morphometry in relation to olfactory function. Using formalin-fixed brains, volumes and linear measurements of the olfactory structures were determined and correlated with those of cerebrum and the whole brain. The volume of the olfactory bulb was greatest in dogs, followed by goats and humans and constituted... |

| Chordae tendineae architecture and their junction with papillary muscle were studied with scanning electron microscopy, comparing human and swine hearts. Papillary muscles with the corresponding chordae tendineae were obtained from human and pig (Sus scrofa) hearts after exposition of the left ventricle cavity, fixed with 4% formaldehyde. The specimens were sectioned in small samples and divided in four groups, a control one and the others submitted to digestion in a solution of 2.5% sodium hypochlorite in saline solution during 5, 10 and 15 minutes respectively. The specimens were washed and fixed in 1% osmium tetroxide in cacodylate buffer, kept in 1% tannic acid for 30 minutes, dehydrated and critical point dried, mounted and sputtered with gold. The... |

| The vomeronasal organ was first described in humans in the seventeenth century. It has a chemosensory function and is found in the mucosa of the nasal septum of mammals and consists of an opening in the mucosa at the base of the nasal septum. For this study, 143 individulas undergoing nasofibrolaryngoscopy were studied, and presence of the vomeronasal organ was considered to be a finding from the examination. Three morphological types of vomeronasal organ were observed: fissure, fossette and circular. The total prevalence of the vomeronasal organ among these patients was 28% (40 individulas ). The prevalence of the vomeronasal organ in this study population is compatible with what has been reported in other studies. The forms of the vomeronasal organ can... |

| The anatomy of mammal's lung air space constitutes the bronchial tree which disposition is associated to air flux dynamics. Casts obtained from human, pig and rat lungs were studied to analyze possible differences of the bronchial tree architecture in mammals with diverse dimensions and posture. Air spaces were filled with polymers through trachea followed by acid corrosion. Tracheal and main bronchial division's diameters were measured to relate with body mass using allometry. The results revealed a dichotomic bronchial branching pattern in the human casts and a monopodial pattern in animals. In allometric relationship trachea was larger in rats, then pigs and lastly in humans, differences were statistically significant, the same occurs in right bronchus,... |

| The variations in morphometric parameter of mammalian brains may be influenced by process of functional complexity, evolution and adaptation. Comparative analysis of linear measurements of cerebrum in the human and baboon has shown morphometric differences. In the present study linear measurements from human and baboon cerebrum (n=10 each) were used to predict various values for human and baboon brain and body parameters through multiple regression models. The average brain weights were found to be 2.08% and 0.84% of the body weights for humans and baboons respectively. The elasticity of regression models revealed that unit percentage increase in Occipital-Frontal (OF) distance would increase the human brain weight by 66.19%, while the baboon brain weight... |

| Deer and sheep are used as spinal animal models in clinical and basic research. In this paper, the anatomical morphology, curvature, and morphology index parameters were investigated to assess the feasibility of using deer and sheep as animal models of the human spine. Fresh adult male sheep, deer, and human spine specimens (n = 10 each) were screened and subjected to morphological analyses. The statistical software package SPSS (version 17.0) was used to analyze the statistical similarity and variability among the 3 species. Deer displayed good similarity to human in terms of the vertebral transverse diameter, radius vector, spinal canal transverse diameter, radius vector, and vertebral upper and lower endplate curvature radii. Sheep displayed good... |

| We investigated the effects of prolonged heat shock treatment on human embryonic stem cell (hESC) viability. The hESC viability steadily declined with longer exposure to heat shock treatment (43ºC). After 4 h of exposure to heat shock at 43ºC, only 56.2 ± 1.5% of cells were viable. Viability subsequently declined to 37.0 ± 3.3% and 3.5 ± 0.7% after 8 h and 16 h, respectively of heat shock treatment at 43ºC. Transmission electron micrographs showed that the morphology of the dead/dying cells after heat shock treatment was characteristic of cellular necrosis with an uncondensed chromatin and a non-intact plasma membrane. This was further confirmed by flow cytometry analysis which showed that the DNA of the dead/ dying cells was still mostly intact, unlike... |

| BACKGROUND: Nitric oxide (NO) has been shown to be important in sperm function, and the concentration of NO appears to determine these effects. Studies have demonstrated both positive and negative effects of NO on sperm function, but have not been able to provide a clear link between NO concentration and the extent of exposure to NO. To study the relationship between nitric oxide and sperm capacitationin vitro, and to provide a theoretical basis for the use of NO-related preparations in improving sperm motility for in vitro fertilization, we investigated the effects of NO concentration and time duration at these concentrations on in vitro sperm capacitation in both normal and abnormal sperm groups. We manipulated NO concentrations and the time duration of... |
