The study aimed to evaluate the comparative anatomy of liver and intrahepatic branching portal vein Eurasian otter (Lutra lutra) American mink (Neovison vison). Due their highly valuable fur, minks have expanded range many parts Europe become available for biomedical studies. In this study, ten adult five otters were used. was studied by combined injection dissection technique. macroscopic reve...

OBJECTIVES To describe a technique for arthroscopy of the fetlock joint of the dromedary camel, and the problems that could occur during and after arthroscopy. METHODS Seven animals (4 cadaveric limbs and 3 living camels) were used in this study. Two dorsal arthroscopic portals (lateral and medial) and one palmaro-lateral portal were used. Distension of the joint capsule was effected by injec...

The Drosophila tracheal system is a stereotypical network of interconnected tubes that supplies air to all cells of the organism. Initially, ten tracheal placodes are defined on both sides of the embryo, each consisting of 20 cells. The placodes undergo two rounds of division, giving rise to the final number of tracheal cells. All subsequent events of tracheal morphogenesis and branch migration...

BACKGROUND The distally based sural artery flap is a reliable, local reconstructive option for small soft tissue defects of the distal third of the leg. The purpose of this study is to describe an adipofascial flap based on a single sural nerve branch without sacrificing the entire sural nerve, thereby preserving sensibility of the lateral foot. METHODS The posterior aspect of the lower limb ...

OBJECTIVE To describe the path of the infrapatellar branch of the saphenous nerve (IBSN) using the medial joint line, anterior tibial tuberosity (ATT), tibial collateral ligament and a horizontal line parallel to the medial joint line that passes over the ATT, as reference points, in order to help surgeons to diminish the likelihood of injuring this nerve branch during reconstruction of the ant...

En face autoradiography of the endothelium was used to quantify the distribution, area, and permeability of sites with enhanced permeability to 125I-low-density lipoprotein (125I-LDL) around the intercostal and celiac arteries and at the iliac bifurcation of normal rabbit aortas. The density of such sites was highest in the upper thoracic aorta and around the celiac and superior mesenteric bran...

The anterior inferior cerebellar artery arises constantly from the basilar artery on each side at the junction of its lowest and middle thirds and passes laterally and downwards to cross the cerebello-pontine angle and the eighth cranial nerve. At this point the internal auditory artery is usually given off, passing almost immediately into the internal auditory meatus. Either immediately before...

BACKGROUND/AIM Soft tissue defects in the distal third of the lower leg are persistent and constitute a major problem in the reconstructive surgery. This study presents an analysis of the anatomical vascularization filed of ascending branch of the peroneal artery ramus perforans (PARS). The aim of this study was to assess reliability of the distal flap on the antero-lateral aspect of a lower le...

Competition and determination of leading and trailing cells during collective cell migration is a widespread phenomenon in development, wound healing and tumour invasion. Here, we analyse this issue during in vivo ganglionic branch cell migration in the Drosophila tracheal system. We identify Sequoia (Seq) as a negative transcriptional regulator of Branchless (Bnl), a Drosophila FGF homologue, ...

A new species of the genus Psithyristria Stål, 1870, Psithyristria ridibunda sp. nov., is described from Quezon, Luzon, Philippines. The new species is very similar to Psithyristria incredibilis Lee & Hill, 2010, but the cubital cell is distinctly larger than the radial cell and the medial branch of the uncal lobe is much shorter than the lateral branch and has two tiny apical spines. Psithyris...
