Revascularization is crucial to liver regeneration after liver injury, but the process remains unclear. This study investigated changes in the levels and distribution of lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1) and prospero homeobox protein 1 (PROX1) in liver tissue sections after partial hepatectomy in mice. Mice were subjected to partial hepatectomy. Control animals were sham-operated. From days 1 through 8, the remaining liver tissues were collected from 8 animals each day. Histology showed that after partial hepatectomy, the remaining liver tissue samples underwent initial degeneration and then hepatocyte proliferation and regeneration...

Venous anomalies discovered on cardiac implantable electronic device (CIED) implantation may hinder both the insertion of cardiac leads and the selection of their optimal intraventricular placement. Such venous anomalies may be a result of congenital vascular defects, e.g. anomalies of the fetal venous system, or be a consequence of earlier cardio- or thoracosurgical procedures. In the case of the latter, the extent of morphometric changes to mediastinal structures may depend on the extent of prior lung tissue resection...

BACKGROUND: Identification and section of pulmonary veins are an essential part of anatomical pulmonary resections. Intraoperative misunderstandings of pulmonary venous anatomy can lead to serious complications such as bleeding and delayed lung infarction or necrosis. We evaluated principally the rate of pulmonary venous anatomical variations, and secondarily the reliability and clinical outcomes of a preoperative morphological analysis. MATERIALS AND METHODS: Between November 2012 and October 2013, we studied 100 consecutive patients with highly suspected or diagnosed stage I-II primitive lung cancer lesion...

The topographical correlations between certain extracranial and intracranial osseous Points of Interest (POIs), and their age-related changes, are indispensable to know for a diagnostical or surgical access to intracranial structures, however, they are difficult to assess with conventional devices. In this pilot study, the 3-dimensional coordinates of extra-/intracranial POIs were determined, thus avoiding perspective distortions that used to be intrinsic problems in 2-dimensional morphometry. The data sets were then analysed by creating virtual triangles...

Inferior vena cava (IVC) is the largest single vein that collects systemic venous blood from the lower part of the body except the gut and drains into the right atrium. Double IVC is a rare anomaly in humans and usually is discovered incidentally during the interventional radiological procedures or routine cadaveric dissection. Here we report a rare case of unusual observations in an adult female Thai cadaver with a duplicated left IVC with three short venous shunts and a variant pattern of the hemiazygos vein...

BACKGROUND: The outcome of the autogrfat therapy for Parkinson's disease including autologous cells from adrenal medulla was disappointing. This could be attributed to the pathological process in Parkinson's disease affecting cells of the adrenal medulla. This study was performed to investigate the histopathological changes in the adrenal medulla of AS/AGU rat, a model of Parkinson's disease, in comparison with Albino Swiss (AS) rats. MATERIALS AND METHODS: A total of 24 male AS rats were divided into four groups, each of 6 animals: AS W1, AS rats aged one week; AS adult, AS adult rats; AS/AGU W1, AS/AGU rats aged one week; and AS/AGU adult, AS/AGU adult rats...

BACKGROUND: Anomalous left brachiocephalic vein (ALBCV) is a rare and less known systemic venous anomaly. Infrequently, this vein takes an abnormal course and passes to the right behind or beneath the aortic arch to create the superior vena cava (SVC). Its incidence was reported much higher in patients with congenital heart disease (CHD) especially in conotruncal and aortic arch anomalies. It could be misdiagnosed with normal or abnormal mediastinal structures. It also could make complication during surgeries or invasive strategies...

BACKGROUND: Acute pancreatitis (AP) is an inflammatory disease that has an increasing incidence worldwide. It is associated with high morbidity and mortality rates ranging from 15-40% in its severe form. Oxidative stress plays an important role in pancreatic acinar cell injury in case of AP. Melatonin is proven to have both antioxidant and anti-inflammatory effects. The aim of the work was to investigate the protective role of melatonin (Mel) against L-arginine (L-arg)-induced AP in adult male albino rats...

Archaeological excavations carried out in the plague cemetery of 16th century Alghero (Sardinia) brought to light the skeleton of a male aged 35-45 years, showing anomalies of the atlas. A macroscopic and radiological study has been carried out. The first cervical vertebra is fused with the skull base, resulting in an occipitalization of the atlas. Absence of the costal element of the left foramen trasversarium, resulting in an open anterior foramen trasversarium, and posterior arch defect are also observed...

The vertebral arteries are commonly affected by anatomical variation. This variation ranges from slight asymmetry in arterial diameter between the right and left sides to complete absence of a vertebral artery on one side. Asymmetry in diameter is a common observation, although complete absence of the artery is rare. Herein, we report on a 79-year-old maleanatomical donor who, upon brain removal, was found to have a single intracranial vertebral artery which was the sole source of the basilar artery. During dissection of the neck, both right and left vertebral arteries were identified arising from the subclavian arteries...
