Avicenna (980-1037 A.D) was the most influential Iranian physician and philosopher in the medieval era. Avicenna composed and compiled treaties on various aspects of medicine in his famous book the Canon of Medicine. Avicenna's treaties have inspired countless debates in all fields of medicine including basic medical sciences. In his treaties, Avicenna adopted the practical approach to the descriptions of the human body and the diseases associated. He made substantial contribution to the medical literature and medical education through his observations and clinical studies...

INTRODUCTION: Heat shock proteins (HSPs) are expressed or overexpressed in response to exposure to stress. They act as molecular chaperones, ensuring the correct folding of numerous client proteins. HSP90 is one of the most conserved HSPs. Its role extends beyond stress tolerance. HSP90 also contributes to development, differenciation, apoptosis and oncogenesis. Numerous tumors are associated with an overexpression of HSP90 and this expression can be used to evaluate its metastatic capacity...

Some authors propose a global approach, including imaging, to describe cranial nerves from a clinical point of view. If we can agree to a certain extent with this proposal, we consider that the use of a medical point of view can neglect histological and embryological features which contribute to a better understanding of nerve function. For example, it is false to consider totally "nerves" I and II as "sensory cranial nerves". They are not true nerves, but derive manly from direct expansions of the central nervous system...

Ibn Sina (also known as Avicenna in the West) was the most famous physician and medical scientist of the medieval era. His book, the Canon of Medicine comprised a vast collection of medical information ranging from basic medical sciences to specialised medical fields. Herein, we present an analysis of the cardiovascular system, particularly giving an in-depth comparison of the structural and functional anatomy of the arteries and veins of the body as described by Avicenna in the Canon of Medicine and comparing them to modern extant anatomical literature...

PURPOSE: Classically, the round ligament of the uterus (RLU) attaches distally in the ipsilateral labia majora. This attachment has rarely been described in adults. That is why we have performed an anatomical study focused on this distal ending. PATIENTS: We performed in 2015 the cadaveric dissection of 19 RLU. METHODS: In all cases, the RLU was individualized on its entire length from its uterine origin to the inguinal canal. Then this canal was open from its internal orifice to its external orifice...

Venous punctures are among the most common procedures performed by healthcare professionals. In particular, the cubital fossa is the site where the venous accesses are frequently made due to the number of superficial veins and the numerous anastomoses in this region. The arrangement of these venous connections is of particular interest for clinical application in several areas, thus, the healthcare professional must possess knowledge about these vessels and their anatomical relationships. The present study aims to analyze the venous pattern of the cubital fossa among individuals from Brazil...

We report the case of a 68-year-old patient, operated on in our department of a quadruple coronary bypass grafting. The grafting strategy consisted initially on harvesting the left internal thoracic artery and the left radial artery. The harvest of this latter failed because of a rare anatomical variation of the radial artery, which rose from the confluence of two branches: a superficial and a deep radial artery at the proximal third of the forearm approximately 10cm below the elbow.

Most osteolytic tumors are in fact mixed and contain an osteoblastic component associated with the predominant osteolytic areas. This metaplastic woven bone is always evidenced by histological analysis even in the absence of radiological expression. Metaplastic bone formation reflects the activation of new osteoblasts coming from the stimulation of the dormant lining cells. Twelve patients with secondary metastases of the iliac crest evidenced by hot spots on a 99 Tc-MBP san were diagnosed by histomorphometry on bone biopsies...

Intra-osseous cholesterol granuloma (CG) is a rare and benign lesion. Very few cases of CG of the jaws have been described in the literature. CG of the jaws seems to be due to the accumulation of cholesterol of hematogenous origin in odontogenic cysts. We report on one case of CG of the maxilla treated by surgical enucleation in a 46-year-old man who presented an asymptomatic swelling of the maxilla.

Implantology research framed the implant surface as a key element for a good and sustainable osseointegration of an implant fixture. The aim of this study was to analyze the antibacterial properties of anatase-coated titanium healing screws through microbiological and scanning electron microscopy. The comparison of the bacterial colonies growth between the anatase-coated titanium healing screws and non-coated titanium healing screws showed comparable antibacterial properties, without significant statistical differences...

The function of the ureterovesical junction depends upon a peculiar structure, the adventitial fibromuscular sheath of Waldeyer, which coats the distal end of the ureter. The origin of the smooth muscle of Waldeyer's sheath (WS) is disputed. Evidence points more likely to an ureteral one. In this regard we hypothesized the WS is not specific to the distal ureter but is rather a common trait. We therefore aimed at exploring whether or not the proximal ureter is provided with a similar adventitial fibromuscular coat...

The cephalic vein arises from the radial end of the dorsal venous arch. It turns around the radial border of the forearm and passes proximally along the arm to the shoulder, where it enters the axillary vein by penetrating the clavipectoral triangle. The cephalic vein is prone to vary at the antecubital fossa, where it forms numerous anastomoses. A male cadaver fixated with a 10% formalin solution was dissected during regular anatomy lessons. It was found that the cephalic vein crossed the upper third of the arm between two fasciculi of the deltoid muscle and reached the shoulder, where it passed above the acromion and crossed the posterior border of the clavicle in order to join the external jugular vein...

Primary hyperoxaluria is a rare genetic disorder characterized by oxalate overproduction, leading to kidney failure due to nephrocalcinosis, and is eventually responsible for systemic oxalosis. Bone impairment, secondary to oxalate deposits, is one of the many complications that may occur. Skeletal involvement can be difficult to diagnose because of lack of clinical symptoms and therefore needs to be confirmed by invasive testing, such as transiliac bone biopsy. If confirmed, bone oxalosis is the proof of disease severity and that combined liver-kidney transplantation should be performed...

Muscles of flexor compartment of forearm have a common origin from medial epicondyle of humerus. Additional bellies of flexor muscles are commonly reported but presence of supernumerary muscles is an infrequent phenomenon. The present study describes an unusual muscle mass in flexor compartment of forearm simulating pronator teres. During routine dissection the upper limb of a 50 years old male cadaver, a supernumerary muscle was found on left side of the upper limb in the flexor compartment. The origin of the muscle was 2cm wide and aponeurotic in nature and attached to an oblique line extending from the inferior surface of the medial epicondyle and the medial surface of the trochlea...

OBJECTIVE OF THE STUDY: To test whether a direct-on-site microscopic examination of fresh, unstained puncture slides by the radiologist decreases the rate of false-negative cases on ultrasound-guided fine-needle cytology of parotid gland masses. PATIENTS: Thirty parotid gland masses from 28 patients were punctured under ultrasound guidance. The same group was used as its control group. METHODS: After one or two passes, the material was spread on slides and air-dried (control group, without microscopic examination)...

A three-headed anterior belly of the digastric muscle (ABDM) on the right side of a 54-year old Greek male cadaver coexisted with two accessory muscle bundles (AMB) in the submental region. The left ABDM was typical. Typical ABDM was attached to the digastric fossa, while the accessory right anterior bellies to the lower border of the mandible. A muscle bundle arising from the attachment of the left ABDM to the hyoid bone was also observed fusing with the AMB of the ipsilateral side. It is of extreme importance to be aware of the submental region anatomical variations during surgery, imaging interpretation or differential diagnosis of neck masses...

The invertebrates, with known exception of echinoderms, are hyponeurian and protostomian. By contrast, echinoderms, chordates and vertebrate are epineurian and deuterostomian. Convinced of the uniqueness origin of all species, Etienne Geoffroy Saint Hilaire (1772-1844), had postulated a complete inversion of body plan to explain this difference. He had to face up to the hostility of the fixist Georges Cuvier (1763-1832). Much later, famous embryologists such as Maurice Caullery still believed that this idea was erroneous...
