Anatomic variations of the extrahepatic biliary tree. A monocentric study and review of the literature.

Introduction: The study of the anatomy of the extra hepatic bile ducts has demonstrated the existence of a significant number of variants which can be explained by hepato-biliary embryology. A good knowledge of this anatomy is essential for the interpretation of radiological examinations, and for a good practice of hepato-biliary and pancreatic surgery. Several imaging methods are used to study the anatomy of the bile ducts, including classical cholangiography, which is still practiced and very useful.

Bacterial adhesion on orthopedic implants.

Orthopedic implants are routinely used for fixation of fractures, correction of deformities, joint replacements, and soft tissue anchorage. Different biomaterials have been engineered for orthopedic implants. Previously, they were designed merely as mechanical devices, now new strategies to enhance bone healing and implant osteointegration via local delivery of molecules and via implant coatings are being developed.

Anthropometric Characteristics of Tunisian Population in Comparison to the World.

Background: Anthropometry is the one and only universally applicable, inexpensive and non-invasive method for studying the proportions of the human body. Anthropometric measurements reflect nutritional status and health, but can also be used to predict skills, health status and survival. It is therefore a reliable tool, but currently underused, to guide public health policies.

Kinematic analysis of the shot-put: A method of assessing the mechanical work of the hand action force.

The aims of this study were to (1) propose a method for evaluating shot-putters mechanical power, (2) investigate the relationship between mechanical work of hand action force (W), peak power output (PPO) of different limbs and shot-put performance and (3) show which of these two parameters (W, PPO) were the most appropriate to characterize the explosive abilities of the shot-putter. Twelve junior right-handed shot-putters, practised glide technique shot-put throwers (personal best = 13.57  ±  1.

[Socio-medical profile of post-polio syndrome patients in center east of Tunisia].

Background: The diagnosis of the post polio syndrome is purely clinic. It occurs few decade after poliomyelitis. It associates recent appearance or progressive worsening of muscular weakness, pain, muscular fatigue or atrophy.

Kinematics in the terminal swing phase of unilateral transfemoral amputees: microprocessor-controlled versus swing-phase control prosthetic knees.

Objectives: To analyze the spatiotemporal parameters in the terminal swing phase of the prosthetic limb in unilateral transfemoral amputees (TFAs) compared with a group of asymptomatic subjects, and to identify a latency period (LP) in the TFA between the full extension of the prosthetic knee and the initial ground contact of the ipsilateral foot. To study the correlation between the LP and the duration of the swing phase. To evaluate the influence of the type of knee, the time since amputation, and the amputation level on the latency period.

The seated man: geometry acquisition and three-dimensional reconstruction.

A three-dimensional (3D) virtual human body in seated position can be used in a wide range of applications such as basic or clinical research. A male cadaver placed in the driving position in a car cockpit was frozen. Strictly parallel 5 mm thickness serial sections were then performed.

Lipolysis of butter oil by immobilized lamb pregastric esterase: I. Uniresponse kinetics-pH and temperature effects.

Lamb pregastric esterase, immobilized by physical adsorption on microporous polypropylene in a hollow fiber reactor, has been employed to effect the continuous hydrolysis of the triglycerides in butter oil. Experimental data were obtained at temperatures from 35 to 45 degrees C and pH values from 5.5 to 6.

Anatomy of the seated position: methodologic approach and initial findings.

The aim of this research was an anatomic study of the seated position in order to reply, in particular, to various questions raised in certain industrial situations as to this position and the reciprocal adaptation of the human being and his seat. The methodology adopted was based on obtaining reference serial sections from an entire subject frozen in the seated position, as well as on computerised three-dimensional reconstruction. The difficulty of the undertaking led us to specify this methodology, which must be strictly adhered to.
