The mucosa of uterine tube forms multiple and branched longitudinal mucosal folds and takes part in many reproduction events, such as oocyte pick-up, gamete transport, sperm capacitation, fertilization, and early embryonic development. In the habilitation thesis of German physician Paul Kroemer (1904) was the first to describe the lymphatic lacunae inside the tubal folds (by injection of Indian ink), which the author named the öLymphbahnen" (ölymphatic channels"). Despite the fact that this first description has existed for 110 years, there is no mention of these lacunae in most of the current literature...

AIM OR PURPOSE: The geometry of a bone defect is very complex. Its shape is too complicated to measure or compare with other bone defects using only traditional measuring methods Traditional measuring techniques based on the histomorphometric analysis of a bone specimen require supplementary measuring. For the fractal dimension analysis (FDA) mathematic formulas are used to describe complicated and chaotic shapes. The FDA offers a possibility of a comparison between complicated and complex shapes such as a histological image of a bone defect...

The main goal of the present study was to determine the influence of low and high doses of acrylamide on CART-like immunoreactivity within the ENS of the porcine small intestines. Investigation was performed on 15 sexually immature female pigs, divided into three groups: control group, where empty gelatin capsules were administered, and two experimental groups, where capsules containing low or high doses of acrylamide were given. After 28days of acrylamide exposure all animals were euthanized with a gradual overdose of anaesthetics...

As calcium and phosphorus are of vital importance for life, physiological activity of the parathyroid glands (PTGs) is crucial to maintain mineral homeostasis and bone mineralization. However, PTG-specific molecular routes in response to environmental factors and intrinsic hormonal responses are not yet fully understood. Since nutrient requirements, pathophysiology and functional genomics of pigs are similar to those of humans, pigs might be a suitable model to study the holistic gene expression and physiological aspects of the parathyroid gland, which could be used in both animal sciences and biomedical research...

Medical schools have traditionally used a lecture and dissection-based approach for educating students about human anatomy. There is growing interest in the adoption of alternative teaching and learning activities (TLAs) that incorporate the use of cadaveric prosection and computer-based learning into musculoskeletal (MSK) anatomy curricula. The purpose of this investigation was to examine retrospectively how different TLAs influenced student perceptions about learning, and performance on MSK anatomy examinations...

This article details our experience with the Terminologia Histologica (TH) and its utility in the teaching of histology, cytology, and clinical medicine (e.g., pathology and hematology). Latin histological nomenclature has been used for 43years, and the latest version of the TH has been in use for 15years (although it was only issued publicly within the past 10years). The following findings and ensuing proposals allow us to discuss key points pertaining to the TH and make important suggestions for potential changes to the TH (such as the exclusion and inclusion of various terms)...

Three-dimensional (3D) printing is a modern technique of creating 3D-printed models that allows reproduction of human structures from MRI and CT scans via fusion of multiple layers of resin materials. To assess feasibility of this innovative resource as anatomy educational tool, we conducted a preliminary study on Curtin University undergraduate students to investigate the use of 3D models for anatomy learning as a main goal, to assess the effectiveness of different specimen types during the sessions and personally preferred anatomy learning tools among students as secondary aim...

Human cadaveric specimens commonly serve as mechanical models and as biological tissue donors in basic biomechanical research. Although these models are used to explain both in vitro and in vivo behavior, the question still remains whether the specimens employed reflect the normal in vivo situation. The mechanical properties of fresh-frozen or preserved cadavers may differ, and whether they can be used to reliably investigate pathology could be debated. The purpose of this study was to therefore examine the mechanical properties of cadaveric long biceps tendons, comparing fresh (n=7) with fresh-frozen (n=8), formalin embalmed (n=15), and Thiel-preserved (n=6) specimens using a Universal Testing Machine...

NGF, BDNF, NT-3 and their specific receptors TrkA, TrkB and TrkC are known to be involved in the development and maintenance of vertebrates' nervous system. However, these molecules play a role also in non-neuronal tissue, such as in the reproductive system. In this study we investigated the presence and localization of neurotrophins and Trk receptors to unravel their potential role in the developing and adult ovary of Japanese quail, a model species well suited for reproduction studies. Western blotting analysis on ovaries of three month old quails in the period of egg laying showed the presence of pro and mature forms of neurotrophins and splice variants of Trk receptors...

While both blood and lymphatic vessels transport fluids and thus share many similarities, they also show functional and structural differences, which can be used to differentiate them. Specific visualization of lymphatic vessels has historically been and still is a pivot point in lymphatic research. Many of the proteins that are investigated by molecular biologists in lymphatic research have been defined as marker molecules, i.e. to visualize and distinguish lymphatic endothelial cells (LECs) from other cell types, most notably from blood vascular endothelial cells (BECs) and cells of the hematopoietic lineage...

Meissner's and Pacinian corpuscles are cutaneous mechanoreceptors responsible for different modalities of touch. The development of these sensory formations in humans is poorly known, especially regarding the acquisition of the typical immunohistochemical profile related to their full functional maturity. Here we used a panel of antibodies (to specifically label the main corpuscular components: axon, Schwann-related cells and endoneurial-perineurial-related cells) to investigate the development of digital Meissner's and Pacinian corpuscles in a representative sample covering from 11 weeks of estimated gestational age (wega) to adulthood...

INTRODUCTION: Optical coherence tomography (OCT) is an imaging tool used in various medical fields (ophthalmology, dermatology), which allows the observation of morphological particularities on the surface of tissues or internal constructive details of about 2-3mms in depth. In periodontology, it has been used as an experimental tool for periodontal pocket analysis (depth, calculus deposits) but not for the assessment of periodontal inflammation in the gingival tissues, which has been the subject of our in-vitro study...

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...

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)...
