INTRODUCTION: Anatomical variations of the first dorsal extensor compartment (1st EC) are commonly noted. MATERIALS AND METHODS: Forty cadaver hands were dissected to define the 1st EC. Through the gross findings, we classified the contents according to the presence of septation, subcompartment, and variation of tendons. Bony cross-section of the wrist was performed to reveal any bony pattern within the 1st EC. We also measured the anatomical structures of the 1st EC...

Orexins are neuropeptides with pleiotropic functions, involved in the coordination of multiple versatile physiological processes, in particular related to food intake and several aspects of the reproductive process. Their actions are carried out through the bond with the related Orexin 1 (OXR1) and Orexin 2 (OXR2) G-protein-coupled receptors. Studies on the expression of the orexinergic system in the female genital organs are scarce and limited to preovulatory gametogenic follicles and corpora lutea isolated from the rest of the ovary...

The effect of a dietary probiotic blend on the carbohydrate composition of mucins secreted by the Brunner's glands in the duodenum of growing-finishing pigs was investigated by means of conventional (periodic acid-Schiff, Alcian Blue pH 2.5, high iron diamine staining) and lectin (15 lectins) histochemistry. Pigs were assigned to two dietary treatments: a control basal diet without the probiotic blend (No-Pro) and a test diet that included the probiotic blend (Pro). Duodenal tissue fragments were fixed in 4% phosphate-buffered-saline-buffered paraformaldehyde, dehydrated through a graded alcohol series, and embedded in paraffin wax...

Cutaneous insertion of the facial mimic muscles concerns, at different levels, the superficial fascia of that region. A superficial musculoaponeurotic system is described at face level that facilitates skin insertion of the facial expression muscles through the superficial fascia that acquires particular functional aspects in each region of the face. The existence of a musculofascial system is seen controversial among anatomists, which is why the purpose of this study is to establish its existence at the oral region...

INTRODUCTION: Information on microscopic anatomy of equine skin is sparse. In horses, limb wounds often become chronic and/or non-healing whereas body wounds heal normally. These dissimilarities in healing patterns might be a product of different phenotypic characteristics of body and limb skin. The objective of this study was to investigate microscopic anatomy, epidermal thickness, keratinocyte proliferation and differentiation as well as the presence of mast cells in normal equine skin of body and limb...

Obesity and aging are associated with periodontitis, which represents a chronic inflammatory disease of the tooth-supporting tissues, i.e. the periodontium. However, if both risk factors also have a negative impact on crestal alveolar bone in a clinically healthy periodontium, has yet to be elucidated and was analyzed in this in-vivo study. Eight C57BL/6 mice were fed a normal diet during the entire study. Half of these mice were sacrificed at week 19 (group 1: younger lean mice), whereas the other half of the animals were sacrificed at week 25 (group 2: older lean mice)...

The first spine of the first dorsal fin (FS) of the Atlantic bluefin tuna (ABFT), Thunnus thynnus, is customarily used in age determination research because its transverse sections display well-defined growth marks. In this paper the FS structure was studied to explain its known dramatic age- and season-related morphological modifications, which are evidently caused by bone remodeling. Cross sections of samples from six adult ABFT were in part decalcified to be stained with histological, histochemical and immunohistochemical methods, and in part embedded in methyl-methacrylate to be either observed under a linear polarized light or microradiographed...

The anatomical variations of the proximal portion of the long head of the biceps brachii tendon (LHBT) are rarely observed in clinical practice. However, an increase in the rate of shoulder arthroscopic surgery has led to an increase in the observation of anatomical variations of this region. The aim of this work was to analyze the development of the LHBT in 23 human embryos ranging from the 6th to 8th weeks of development. The LHBT develops from the glenohumeral interzonal mesenchyme in the 6th week. By week 7, the myotendinous junction of the LHBT develops...

Inflammatory bowel disease (IBD) is a complex gastrointestinal disorder and its etiology is unclear yet. Current theory in IBD is focused on genetics, immunity and intestinal microbes. Emerging clinical evidence and experimental results suggest that morphologic abnormalities and dysfunction of mesenteric lymphatics may have potential roles in the pathogenesis and disease course of IBD. In this review, we summarize the findings of specific investigations of the lymphatics and explore its role in IBD.

The neuromast is the morphological unit of the lateral line of fishes and is composed of a cluster of central sensory cells (hair cells) surrounded by support and mantle cells. Heavy metals exposure leads to disruption of hair cells within the neuromast. It is well known that the zebrafish has the ability to regenerate the hair cells after damage caused by toxicants. The process of regeneration depends on proliferation, differentiation and cellular migration of sensory and non-sensory progenitor cells. Therefore, our study was made in order to identify which cellular types are involved in the complex process of regeneration during heavy metals exposure...

Attaining molecular and morphological axial polarity during gastrulation is a fundamental early requirement for normal development of the embryo. In mammals, the first morphological sign of the anterior-posterior axis appears anteriorly in the form of the anterior marginal crescent (or anterior visceral endoderm) while in the avian the first such sign is the Koller's sickle at the posterior pole of the embryonic disc. Despite this inverse mode of axis formation many genes and molecular pathways involved in various steps of this process seem to be evolutionary conserved amongst amniotes, the nodal gene being a well-known example with its functional involvement prior and during gastrulation...

Microglia represent the resident macrophages of the central nervous system (CNS). While it is clear that microglia recruitment is established by differentiation of primitive yolk sac (YS) macrophages and consecutive invasion of the brain, starting around E8 in rodents (Ginhoux et al., 2010), more recent studies suggest that a non-YS contribution to the microglia population should not entirely be dismissed (Swinnen et al., 2013; Xu et al., 2015). Therefore, we used Vav1-Cre+ :dicer knock-out mice in order to study the effect of the post-YS hematopoiesis on the definitive microglial population in late prenatal (E16...

OBJECTIVE: plasma of argon treatment was demonstrated to increase material surface energy leading to stronger and faster interaction with cells. The aim of the present in vitro study was to test the effect of plasma treatment on different graft materials. MATERIALS AND METHODS: synthetic hydroxyapatite (Mg-HA), biphasic calcium phosphate (BCP), cancellous and cortical xenogeneic bone matrices (CaBM, CoBM) were used representing commonly used classes of bone substitute materials...

Telocytes (TCs) are stromal cells defined by the presence of long and slender prolongations (telopodes). They are a biologically and functionally heterogeneous population that has not been previously investigated in the sclera. The purpose of this study is to investigate the presence and characteristics of scleral telocytes through a combined immunohistochemical and transmission electron microscopy (TEM) study using samples from ten adult patients. Stromal cells with a TC-like morphology expressed CD34, CD45, CD105, vimentin and occasionally CD68 but were negative for collagen III, CD31, CD133, and CD146...

Stromal cells/telocytes (SCs/TCs) were recently described in the human adult trigeminal ganglion (TG). As some markers are equally expressed in SCs/TCs and endothelial cells, we hypothesized that a subset of the TG SCs/TCs is in fact represented by endothelial progenitor cells of a myelomonocytic origin. This study aimed to evaluate whether the interstitial cells of the human adult TG correlate with the myelomonocytic lineage. We used primary antibodies for c-erbB2/HER-2, CD31, nestin, CD10, CD117/c-kit, von Willebrand factor (vWF), CD34, Stro-1, CD146, α-smooth muscle actin (α-SMA), CD68, VEGFR-2 and cytokeratin 7 (CK7)...

REVIEW

Our understanding of lymphatic vessels has been advanced by the recent identification of relatively specific lymphatic endothelium markers, including Prox-1, VEGFR3, podoplanin and LYVE-1. The use of lymphatic markers has led to the observation that, contrary to previous assumptions, human lymphatic vessels extend deep inside the pulmonary lobule, either in association with bronchioles, intralobular arterioles or small pulmonary veins. Pulmonary lymphatic vessels may thus be classified into pleural, interlobular (in interlobular septa) and intralobular...

INTRODUCTION: digital virtual simulation (DVS) is increasingly used to supplement the teaching of anatomy. DVS can provide the students with three-dimensional (3D) stereoscopic images and precise structures in anatomy teaching. We investigated the effects of digital virtual simulation (DVS) application in gross anatomy teaching. MATERIALS AND METHODS: fourth-year medical students (n=120), majoring clinical medicine in 2013 grade from Xiangya School of Medicine, Central South University, were assigned into four classes...

Osteoblast cell adhesion to the extracellular matrix is established through two main pathways: one is mediated by the binding between integrin and a minimal adhesion sequence (RGD) on the extracellular protein, the other is based on the interactions between transmembrane proteoglycans and heparin-binding sequences found in many matrix proteins. The aim of this study is the evaluation in an in vivo endosseous implant model of the early osteogenic response of the peri-implant bone to a biomimetic titanium surface functionalized with the retro-inverso 2DHVP peptide, an analogue of Vitronectin heparin binding site...

The peptide hormone cholecistokinin (CCK) plays a key role in the central and peripheral nervous system. It is known to be involved in the digestive physiology and in the regulation of food intake. Moreover, the CCK expression has also been detected in the retina of different vertebrates, including fish, although its biological activity in this tissue remains to be elucidated. In literature no data are yet available about the CCK-immunoreactivity in the zebrafish retina during development. Therefore, the aim of the study was to investigate the distribution of sulfated cholecystokinin octapeptide (CCK8-S) as a well preserved form during evolution in the zebrafish retina from 3days post hatching (dph) until adult stage, using immunohistochemistry in order to elucidate the potential role of this protein in the development and maintenance of normal retinal homeostasis...
