Mugurel Constantin Rusu, Sorin Hostiuc
The study of cardiac interstitial Cajal-like cells (ICLCs) began in 2005 and continued until 2010, when these cells were renamed as telocytes (TCs). Since then, numerous papers on cardiac ICLCs and TCs have been published. However, in the initial descriptions upon which further research was based, lymphatic endothelial cells (LECs) and initial lymphatics were not considered. No specific antibodies for LECs (such as podoplanin or LYVE-1) were used in cardiac TC studies, although ultrastructurally, LECs and TCs have similar morphological traits, including the lack of a basal lamina...

BACKGROUND: The fibular collateral ligament (FCL) is subject to varus forces at all knee flexion angles and is also resistant to external rotation near extension. It originates on the lateral epicondyle of the femur and inserts on the lateral surface of the head of the fibula. However, its anatomical characteristics are inconsistent. Recent publications have focused on morphological variations concerning mainly femoral and fibular attachments, as well as morphometric measurements. Less attention has been paid to the morphology of the FCL and its relationship to the antero-lateral ligament (ALL)...

The aim of this work is to assess the association between the patterns of bone modeling and the changes in shape and size of the maxilla along ontogeny in modern humans. The sample analyzed includes an ontogenetic series of 30 individuals from an archaeological site from Pampa Grande, northwest of Argentina. The areas of bone resorption and formation were described by histological analysis of bone surfaces and then quantified using spatial statistics. Morphological changes were analyzed by geometric morphometric methods using landmarks and semilandmarks digitized on 3D surfaces obtained from CT-scans...

BACKGROUND: The lateral pterygoid muscle (LPM) has been described in many anatomical and functional studies. The morphology of the LPM is still under debate because of its deep location in the infratemporal fossa and the difficulties to approach this area with different anatomical methods Although it has been generally accepted that this muscle is mainly composed of two separate parts, other forms have been described in the past. OBJECTIVES: To conduct a systematic literature review regarding the anatomy and variations of the LPM...

The practice of human and veterinary medicine is based on the science of anatomy and dissection courses are still irreplaceable in the teaching of anatomy. Embalming is required to preserve body donors, for which process formaldehyde (FA) is the most frequently used and well characterized biocidal substance. Since January 2016, a new occupational exposure limit (OEL) for FA of 0.37mg/m3 issued by the European Committee on Hazardous Substances is obligatory since FA has been classified as a human 1B carcinogen...

PURPOSE: Although anatomy is a significant part of medical education, there is controversy surrounding the appropriate method of anatomy teaching. Although social media is used in medical teaching, it has not been clarified if social platforms could significantly influence anatomy education. The purpose of this narrative review was to investigate to what extent the existing literature supports that social media could play a significant role in anatomy education. METHODS: PubMed, Scopus, Web of Science, Cochrane database of systematic reviews, ERIC and CINAHL plus were searched for studies with a purpose to investigate the correlation between social media and anatomy education...

CONTEXT: The practice of anatomical dissection and/or prosection on human cadavers is an essential component of human anatomy training programmes. However, this activity can be stressful for inexperienced students when exposed to cadavers for the first time, and it may generate high anxiety levels. The aims of this study are threefold: 1) to analyse the thoughts and feelings of first-year students of the Occupational Therapy degree about prosection practices; 2) to examine their anxiety levels in relation to these practices; and 3) to evaluate how useful and effective they are as an educational tool for anatomy training...

Assessment of structural cartilage damage is of high scientific and clinical interest. Optical Coherence Tomography (OCT) is a light-based cross-sectional imaging modality that allows the real-time assessment of articular cartilage at near-histological resolution. Algorithm routines for the detection, parameterization and quantification of sub-surface defects as assessed by OCT were implemented and validated in this study. Standard defects of 0.9mm, 1.1mm and 1.3mm diameter were created in the sub-surface regions of macroscopically intact human articular cartilage samples (n=60 defects of variable sizes in n=20 samples)...

N-myc downstream-regulated gene 2 (NDRG2) has been implicated in the development of central nervous system and brain diseases such as brain tumors, ischemic stroke and neurodegenerative disorders. However, it remains unclear that the spatiotemporal distribution of NDRG2 in the human fetal brain. In this study, we examined the expression pattern of NDRG2 in different regions of human fetal brain at 16-28 gestational weeks (GWs) by using RT-PCR, western blot and immunohistochemistry. Firstly, RT-PCR revealed that mRNA of NDRG2 was detected in the human brain regions of fetuses at 16-28 GWs such as medulla oblongata (MdO), mesencephalon (MeE), cerebellum (Cbl), frontal lobe (Fr), ventricular (VZ)/subventricular zone (SVZ) and hippocampus (hip), and the expressions of NDRG2 mRNA in these human fetal brain regions were increased with gestational maturation...

Anatomy is a cornerstone of medical undergraduate curricula. Due to increasing changes in various medical fields, a lot of new subjects were introduced in undergraduate curricula, while the teaching areas of basic sciences, i.e. anatomy, were reduced. The introduction of advanced diagnostic and therapeutic devices, i.e. ultrasound and laparoscopy, with outstanding imaging quality will be increasingly introduced in basic sciences. In our project, we examined the effect integrating ultrasound and laparoscopy in an anatomy undergraduate course to illustrate the female pelvis...

OBJECTIVE: Heat pre-treatment of mechanically loaded human periodontal ligament cells (hPDL) dampens the inflammatory cellular response, as evidenced by a reduced expression of pro-inflammatory cytokines, inhibition of monocyte adhesion and osteoclastic differentiation. These findings imply heat shock proteins (HSP) as cell protective molecules acting in the PDL that are up-regulated upon ischemia caused by mechanical loading. HSP70 and its inhibition by VER155008 as the active agent in several pharmaceuticals are established targets and strategies, respectively, in the treatment of neoproliferative diseases...

The purpose of this study is to investigate whether calpastatin (CAST) plays an important role in the regulated necrosis (RN) in rat retinal neurons under an excessive glutamate condition and furthermore to investigate whether this process is regulated by calapin1 and calpain2. In the present study, glutamate triggered CAST inhibition, calpain2 activation and retinal neuronal RN after injury. The application of CAST active peptide could provide protective effects against activated calpain2 mediated RN. However, the calpain1 activity was not changed in these processes...
