This paper reports on the analysis of the signals sent by accelerometers fixed on the axles of a vehicle which passes over a bridge. The length of the bridge is divided into some parts and the transmissibility measurement is applied to the signals recorded by two following instrumented axles. As the transmissibility procedure is performed on the divided signals, the method is called Short Time ...

A 2-day-old male baby presented with abdominal distension and failure to pass meconium. The perineal examination revealed normally placed patent anus. A rectal examination with thermometer revealed a resistance at 2-3cm from the anal verge. A contrast enema was given to document the suspicion of rectal atresia. The contrast enema revealed a 2cm long stenosis of the rectum opening abruptly into ...

Neem oil was obtained from the seeds of the neem tree, Azadirachta indica, exploiting a manually operating bridge press, and used to prepare toilet soap. The chemical properties of the soap were 63.75 %, 0.24 %, 0.06, 1.15 %, 12.6 % and 10.4 as its total fatty matter, total alkali, free caustic alkali, percentage chloride (% Cl), % moisture and pH respectively. Due to the phytoconstituents in n...

Introduction Schwann cells differentiated from skin-derived precursors (SKP-SCs) have been shown to promote histological and functional recovery in a contusion model of rat spinal cord injury [1]. Cellular bands of SKP-SCs bridge the lesion site which promote axon growth ensheathed by peripheral (Schwann cell) myelin of endogenous as well as transplant origins. In this work, we assess the myeli...

Near total amputation of the upper limb if unsalvageable would cause severe disability. However, delayed revascularisation can be life threatening. We report two cases of revascularisation of the upper limb following near total amputation that was successful and functional after a warm ischaemic time of ten hours. The first was a traction avulsion injury of the arm leaving major nerves contused...

When current of proper polarity and sufficient intensity is passed across isolated frog skin or toad bladder, an action potential of about 200 mv and 10 msec. duration with a sharp threshold and refractory period of several seconds' duration is elicited. Interruption of current during the action potential abolishes the response, and, as shown by appropriate bridge measurements, this occurs beca...

Tissue expansion is a popular technique in plastic and reconstructive surgery that grows skin in vivo for correction of large defects such as burns and giant congenital nevi. Despite its widespread use, planning and executing an expansion protocol is challenging due to the difficulty in measuring the deformation imposed at each inflation step and over the length of the procedure. Quantifying th...

Background and objectives: Perforator flaps, both pedicled and free flaps, are increasingly used in reconstructive surgery. However, the microvascular perfusion pattern within these flaps still remains essentially unknown. It is well known that in random-pattern flaps, flap length correlates directly with the width of the flap base. In perforator flaps, the importance of preserving a skin base ...

Patterns form with the break of homogeneity and lead to the emergence of new structure or arrangement. There are different physiological and pathological mechanisms that lead to the formation of patterns. Here, we first introduce the basics of pattern formation and their possible biological basis. We then discuss different categories of skin patterns and their potential underlying molecular mec...
