The gross anatomy and morphometry of the kidney and renal arteries were studied in the strains of laboratory rat: Sprague-Dawley (Sp) and Wistar (W) rats. Total of 106 three-dimensional endocasts of the intrarenal arteries of kidney that were prepared using standard injection-corrosion techniques were examined. A single renal artery was observed in 100% of the cases. The renal arteries were divided into a dorsal and a ventral branch. The dorsal and ventral branches were divided into two branches, the cranial and caudal branch. Renal arteries were classified into types I and II, depending on the cranial and caudal branches and their made of branching. The present study also showed that the right kidney was slightly heavier than the left one and that the kidney of the male was generally larger than that of the female. The mean live weights of the Sprague-Dawley and Wistar rats were found to be 258.26 ± 5.9 and 182.4 ± 19.05g, respectively. The kidney weights were significantly correlated () with body weights. The kidney weights were not found significantly correlated () with the length of renal arteries.

The acute phase effects of toluene on the brain have been investigated in this study using rabbit brain via histopathological, immunohistochemical, and biochemical methods. A total of 20 male rabbits were used as control and experimental groups. Moreover, nerve growth factor (NGF), tumor necrosis factor-alpha (TNF-alpha), dopamine (DA), and glial fibrillary acidic protein (GFAP) tests were performed in order to designate the severity of the biochemical damage. In the biochemical evaluation of the prefrontal cortex, hippocampus, hypothalamus, substantia nigra, and entorhinal cortex, the TNF-alpha levels in the brain were found to be significantly higher than in the control group. Levels of dopamine, secreted from the substantia nigra, nerve growth factor (NGF) developed from the hippocampal neurons, and GFAP, secreted from astrocyte cells, were detected to be significantly lower in the toluene-administration group than in the control group (p<0.05). In addition, areas of focal vacuolar degeneration (abscess formation), gliosis, and perivascular demyelination, many pyknotic cells and necrosis were observed. In the toluene-administration group compared to the control group, distinct excessive expansions of the blood vessels and severe degeneration in the structure of cells and also dispersed cell borders were observed. Furthermore, abnormal malformations of the nuclei structure of the oligodendrocyte cells were seen. Bodies of the sequential neurons of the hippocampus in the toluene-administration group were distinctly structurally damaged compared to the control group. In addition, cytoplasm of the cortex cell showed serious immune reactivity in the experimental group.

A total of 25 (13 male, 12 female) adult, healthy Swiss albino mice were used to investigate the origin, course and anastomoses of coronary arteries. Coloured latex was injected into the aortic arch to enable these arteries to be clearly discerned. A. coronaria sinistra was larger than A. coronaria dextra. It was divided into a Ramus interventricularis paraconalis and a Ramus circumflexus sinister. However, in 2 specimens, the septal ramus, was observed to stem directly from the left coronary artery, and only 1 ventricular branch arose from the left circumflex. The collateral branches of the paraconal interventricular ramus had a larger diameter and more extensive distribution was observed in these specimens. The A. coronaria dextra was divided into a Ramus septalis and Ramus circumflexus dexter. The Ramus interventricularis subsinuosis was not detected in this study. The ventricular branches of the left coronary artery run intramyocardially whereas the branches of the right coronary artery course subendocardially.

To investigate experimentally the effects of Tropifexor, a farnesoid X receptor agonist, on liver injury in rats with obstructive jaundice. Forty healthy Wistar albino female rats were divided randomly in selected groups. These groups were the sham group, control group, vehicle solution group, Ursodeoxycholic acid group and Tropifexor group. Experimental obstructive jaundice was created in all groups, except the sham one. In the blood samples obtained, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total bilirubin and direct bilirubin levels were established and recorded. Additionally, liver malondialdehyde, myeloperoxidase and catalase enzyme activity in the tissue samples were studied. Histopathological analysis was also performed. No statistical difference was found between the control group and the Tropifexor group when AST, ALT and ALP values were compared. However, it was found that the Tropifexor group had statistically significant decreases in the values of GGT, total bilirubin and direct bilirubin (p < 0.05). Additionally, Tropifexor decreased the median values of malondialdehyde and myeloperoxidase, but this difference was not statistically significant compared to the control group. Finally, the Tropifexor group was statistically significant in recurring histopathological liver damage indicators (p < 0.05). Tropifexor reduced liver damage due to obstructive jaundice.

Spor yaralanmaları, sportif faaliyetler sırasında karşılaşılan, bireysel ya da çevresel faktörlerden dolayı oluşabilen yaralanmalardır. Spor yaralanmalarının özellikleri, yapılan spor branşına göre farklılık gösterir. Bu çalışma voleybolcularda görülen kas-iskelet sistemi yaralanmalarını tespit etmek, kinezyofobi düzeylerini incelemek, sporculara ait bazı kişisel bilgiler ile yaralanma ve kinezyofobi arasındaki ilişkiyi incelemek amacıyla yapılmıştır. Voleybol branşında 102 sporcu (61 kadın ve 41 erkek) çalışmaya dahil edildi. Sporcuların yaralanmaları “Kas-İskelet Sistemi Anketi” ile değerlendirildi. Sporcuların kinezyofobi düzeyleri “Tampa Kinezyofobi Ölçeği” ile değerlendirildi. Ayrıca, sporcular demografik bilgilerini içeren kişisel bilgi formunu da doldurdular. Verilerin değerlendirilmesinde SPSS 22 programı kullanıldı. Sonuçlar frekans, yüzde dağılımı, t testi, anova testi ve ki-kare testleri ile değerlendirildi. Anlamlılık düzeyi “p<0.05” olarak kabul edildi. Çalışmaya katılan sporcular arasında 75 sporcunun en az bir bölgesinde yaralanma ile karşılaştığı, bölge olarak en fazla yaralanmanın %40.2 oranıyla omuzda olduğu belirlendi. Yaralanmaların görüldüğü bazı vücut bölgeleriyle sporcuların bazı demografik bilgileri istatistiksel olarak anlamlı düzeyde farklılık göstermektedir. Cinsiyet ile bel ve boyun yaralanması, sporcunun voleyboldaki pozisyonu ile bel ve sırt yaralanması, haftalık antrenman sayısı ile ayak-ayak bileği yaralanması arasında anlamlı düzeyde ilişki çıkmıştır (p 0.05).

Background: It is well known that rodents are defined by a unique masticatory apparatus. The present study describes the design and structure of the masseter muscle of the blind mole rat (Spalax leucodon). The blind mole rat, which emerged about 5.3–3.4 million years ago during the Late Pliocene period, is a subterranean, hypoxia-tolerant and cancer-resistant rodent. Yet, despite these impressive characteristics, no information exists on their masticatory musculature. Materials and methods: Fifteen adult blind mole rat were used in this study. Dissections were performed to investigate the anatomical characteristics of the masseter muscle. Results: The muscle was comprised of three different parts: the superficial masseter, the deep masseter and the zygomaticomandibularis muscle. The superficial masseter originated from the facial fossa at the ventral side of the infraorbital foramen. The deep masseter was separated into anterior and posterior parts. The anterior part of the zygomaticomandibularis muscle arose from the snout and passed through the infraorbital foramen to connect on the mandible. Conclusions: The construction of the deep masseter and zygomaticomandibularis muscles were of the Myomorpha type. Further studies are needed to reveal features such as muscle biomechanics, muscle types. Background: It is well known that rodents are defined by a unique masticatory apparatus.
