Fibroblast Growth Factors 1-2 (FGF1-2) stimulate tail regeneration in lizards and therefore the distribution of their receptors, FGFR1-2, in the regenerating tail of the lizard. Podarcis muralis has been studied using immunofluorescence and western blotting. Immunoreactive protein bands at 15-16kDa for FGF1-2 in addition to those at 50-65kDa are detected in the regenerating epidermis, but weak bands at 35, 45 and 50kDa appear from the regenerating connective tissues. Strongly immunolabeled bands for FGFR1 at 32, 60, and 80kDa and less intense for FGFR2 only appear in the regenerating tail...

Acetylcholine is synthetized and released from neural cells, but also by non-neuronal cells such as epithelial cells or keratinocytes. Cholinergic agonists enhance the phagocytosis of zymosan particles in primary peritoneal macrophages. The aim of this study was to investigate the effect of carbachol stimulation on phagocytosis in a macrophage cell line using microspheres. The murine cell line MH-S was used in a phagocytosis assay with fluorescent latex beads. The amount of the ingested beads was determined using flow cytometry...

The study of anatomical variations is important not only for collecting anthropometric data, but also for improving clinical protocols and understanding why a particular clinical procedure sometimes does not yield the expected results. We report the case of a 74 year-old patient, in which we observed combined anatomical variants of the mandible and maxillary bone. One of these was the unilateral mylohyoid bridge (MB) of the uncommon, lingular type. This MB extended posteriorly to the spine of Spix, over the sulcus colli behind the spine...

BACKGROUND: The cellular and molecular mechanisms implicated in age-associated changes in myocardial structure are of paramount importance since they cause profound alterations in the functional response and represent targets for alleviating age-related pathologies. One of these mechanisms is the JAK/STAT/SOCS signaling pathway. AIM OF THE STUDY: The present study is designed to elucidate age-dependent changes of the myocardium to provide morphological basis displaying the pathogenesis of myocardial hypertrophy, fibrosis and inflammation with aging...

BACKGROUND: Chronic alcohol consumption is a known limiting factor for bone healing. One promising strategy to improve bone augmentation techniques with Bio-Oss(®) in oral and maxillofacial surgery might be the supportive application of platelet-concentrated biomaterials as platelet-released growth factor (PRGF). To address this matter, we performed an in vitro study investigating the protective effects of PRGF and Bio-Oss(®) in ethanol (EtOH) treated osteoblasts. METHODS: The SAOS-2 osteosarcoma cell line, with and without EtOH pretreatment was used...

Although the traditional didactic lecture is considered to be efficient for presenting information and providing explanations, it usually does not provide adequate time for deeper learning activities. So, traditional lecture is one of the most widely criticized educational methods. Virtual learning environment (VLE) is a specially designed environment that facilitates teachers' management of educational courses for their students, using computer hardware and software, which involves distance learning. In this study, we evaluated the experiment of online teaching of General Embryology for Egyptian undergraduate medical students using WizIQ learning management system...

In vertebrates, skeletal muscles of the body are made up of epaxial and hypaxial muscles based on their innervation and relative position to the vertebral column. The epaxial muscles are innervated by the dorsal branches of the spinal nerves and comprise the intrinsic (deep) back muscles, while the hypaxial muscles are innervated by the ventral branches of the spinal nerves including the plexus and consist of a heterogeneous group of intercostal, abdominal, and limb as well as girdle muscles. The canonical view holds that the epaxial muscles are derived from the medial halves of the somites, whereas the hypaxial muscles are all derived from the lateral somitic halves...

Details of the human facial parotid plexus (PP) are not readily accessible during ordinary anatomical teaching because of insufficient time and difficulties encountered in the preparation. For parotid and facial nerve surgery however, precise knowledge of PP is of crucial importance. The aim of this study was therefore to provide more details of PP in anatomic specimens. Following anatomical dissection, its location, syntopy and morphology were analyzed in 158 cervico-facial halves of 95 cadavers. The facial nerve (FN) divides into a larger temporo-facial and a smaller cervico-facial trunk...

Many types of bone substitute materials are available on the market. Researchers are refining new bone substitutes to make them comparable to autologous grafting materials in treatment of bone defects. The purpose of the study was to evaluate the osseoconductive potential and bone defect regeneration in rat calvaria bone defects treated with new synthetic nano-hydroxyapatite. The study was performed on 30 rats divided into 5 equal groups. New preproduction of experimental nano-hydroxyapatite material by NanoSynHap (Poznań, Poland) was tested and compared with commercially available materials...

Back muscles are commonly described in a topographically-oriented manner without necessarily following morphological criteria. In this manner, non-standard terms may be employed which convey incorrect morphological concepts and demanding more time from both faculty and students to transmit knowledge. We propose a classification system for spinal muscles incorporating morphological concepts with the goal of facilitating knowledge transfer and suggest the term "spinal muscles". Those muscles were systematically divided and classified in seven strata from anterior to posterior: vertebro-appendicular (VA), transversarium (Tr), deep post-transversarium (DPT), middle post-transversarium (MPT), superficial post-transversarium (SPT), deep spino-appendicular (DSA) and superficial spino-appendicular (SSA)...

Short dental implants can be an alternative method of treatment to a vertical bone augmentation procedure at sites of reduced alveolar height. However, for successful treatment, an implant system that causes a minimal marginal bone loss (MBL) should be taken into consideration. The aim of the study has been to evaluate implantation effectiveness for bone level and tissue level short implants provided in lateral aspects of partially edentulous mandible and limited alveolar ridge height. The MBL and primary as well as secondary implant stability were determined in the study...

Antlers are the cranial appendages of deer that regenerate each year. This renewal provides a model to explore molecules involved in mammalian organ regeneration. The cellular distributions of the brain-derived neurotrophic factor (BDNF) and the isoforms of its cognate receptor Trk tyrosine kinase receptor (TrkB) were localized by immunohistochemistry in sections of growing red deer antler. BDNF and TrkB full length were widely expressed in the integument, perichondrium, periosteum and bone. The truncated isoform receptor was particularly evidenced in integument and vascular inner dermis, but very light reaction was observed in cartilage and bone, both at the site of endochondral and intramembranous ossification...

In teaching and learning human anatomy, anatomical autopsy and prosected specimens have always been indispensable. However, alternative methods must often be used to demonstrate particularly delicate structures. Corrosion casting of porcine organs with Biodur E20(®) Plus is valuable for teaching and learning both gross anatomy and, uniquely, the micromorphology of cardiovascular, respiratory, digestive, and urogenital systems. Assessments of casts with a stereomicroscope and/or scanning electron microscope as well as highlighting cast structures using color coding help students to better understand how the structures that they have observed as two-dimensional images actually exist in three dimensions, and students found using the casts to be highly effective in their learning...

Millions of patients around the world suffer minor or major extremity amputation due to progressive wound healing complications of chronic or infected wounds, the therapy of which remains a challenge. One emerging therapeutic option for the treatment of these complicated wounds is the local application of an autologous thrombocytes concentrate lysate (e.g. platelet-released growth factors ((PRGF)) or Vivostat PRF(®)) that contains a multitude of chemokines, cytokines and growth factors and is therefore supposed to stimulate the complex wound healing process...

Inflammatory mechanisms and oxidative stress play important roles in age-related lacrimal gland (LG) degeneration as well as neural degeneration. Research suggests that caloric restriction can prevent age-related LG dysfunction and increase the life span of neurons. In the present study, we hypothesized that caloric restriction prevents age-related LG dysfunction by ameliorating the influence of inflammatory/oxidative stress on autonomic neurons controlling lacrimal function. We evaluated the effects of food restriction (FR) on inflammatory/oxidative status and on autonomic neural/neuroglial cell populations in LGs from aging rats...

Interprofessional collaboration between different professional groups in the health care system is essential to efficient and effective patient care. Especially in pediatrics, in the field of child protection, and family services it is mandatory to involve experts from different health-care professions to optimize support for children and their families. Interprofessional education in medical schools and specifically in pediatrics is rare in Germany, but is called for by the German National Competence Based Catalogue of Learning Objectives for Undergraduate Medical Education (NKLM)...

The infra-patellar fat pad (IPFP) has been proposed to represent an endocrine link between obesity and knee osteoarthritis (OA). The purpose of the current study has been to explore the extent to which IPFP volume is related to body mass index (BMI). A total of 152 participants (age 56±7 years) without knee OA were studied. These consisted of 19 men and 19 women of normal weight (BMI 18.5-25), 19/19 pre-obese (BMI 25-30), 19/19 obese class I (BMI 30-35) and 19/19 obese class II (BMI 35-40), who were matched 1:1 for age and height...

The trochlear nerve is generally considered to be a purely motor nerve supplying one extraocular muscle, the superior oblique. In the current study, 28 orbits were dissected and in one orbit (3.6%), the trochlear nerve divided into two main branches. The medial branch followed the classical course, entered the superior oblique muscle and was presumed to be motor in function. However, before entering the muscle, it partially fused with the frontal nerve, and gave a bundle of nerve fibres to the frontal nerve...
