A Classic Case of Annular Pancreas and its Clinical Implications
Nayak B,Satheesha; Mun Yooi,Ooi;
International Journal of Morphology , 2011, DOI: 10.4067/S0717-95022011000200043
Abstract: annular pancreas is a rare developmental anomaly where the head of the pancreas surrounds the second part of the duodenum like a ring. this may cause the duodenal constriction, obstruction, peptic ulcers and other complications. we saw a classic case of annular pancreas. the head of pancreas surrounded the second part of duodenum completely. however there was no narrowing of the duodenum. the case may be of importance for gastroenterologists, surgeons and radiologists.
Sural nerve and short saphenous vein entrapment-a case report
Nayak Satheesha
Indian Journal of Plastic Surgery , 2005,
Abstract: Although the sural nerve is the most extensively studied nerve in man, there is a dearth of data regarding the normal variations in the size and distribution of axons in normal subjects. Since the sural nerve is the most frequently used sensory nerve in nerve transplantation, knowledge of variations in its course and distribution plays an important role in the surgical procedures. Here, an entrapment of the sural nerve in the gastrocnemius is reported. The short saphenous vein also passed through the gastrocnemius muscle along with the sural nerve.
Abnormal Branch of External Iliac Artery in the Iliac Fossa
Nayak B,Satheesha;
International Journal of Morphology , 2008, DOI: 10.4067/S0717-95022008000200033
Abstract: an abnormal artery arising from external iliac artery was found during routine dissection class for medical undergraduates. the artery took its origin from the external iliac artery midway between its origin from common iliac and termination as femoral artery. the abnormal artery divided into two branches; an ascending and a descending. the ascending branch supplied iliacus and iliac crest. the descending branch entered the femoral triangle by passing behind the femoral sheath. it supplied the muscles of femoral triangle and anastomosed with medial circumflex femoral artery. the knowledge of this variation may be of use for surgeons doing surgery of femoral hernia.

The knowledge of this variation may be of use for surgeons doing surgery of femoral hernia. Una variación arterial proveniente de la arteria ilíaca externa fue encontrada durante una disección de rutina en Medicina de pregrado. La arteria se originaba de la arteria ilíaca externa a mitad de camino entre su origen desde la arteria ilíaca común y su terminación, la arteria femoral. La arteria se dividía en dos ramas: ascendente y descendente. La rama ascendente suministraba la irrigación al músculo ilíaco y a la cresta ilíaca. La rama descendente entraba en el trígono femoral pasando por detrás de la vaina femoral y daba la irrigación a los músculos del trígono femoral, anastomosándose con la arteria circunfleja femoral medial. El conocimiento de esta variación puede ser de utilidad para los cirujanos que realizan cirugía de hernia femoral.

Abstract: A rare case of unilateral third head of sternocleidomastoid muscle was noted during routine dissections for undergraduate medical students. The additional third head originated from the middle third of the clavicle and joined the normal two heads (sternal and clavicular) of the muscle in the middle of the neck. The insertion and nerve supply of the muscle was normal. This case may be important for head and neck surgeons and for plastic surgeons doing muscle graft surgeries. Un caso raro de una tercera cabeza unilateral del músculo esternocleido-mastoideo se observó durante disecciones de rutina para los estudiantes de medicina de pregrado. La tercera cabeza adicional se originó en el tercio medio de la clavícula y se unió a las dos cabezas normales (esternal y clavicular) del músculo en el medio del cuello. La inserción y e inervación del músculo fue normal. Este caso puede ser importante para los cirujanos de cabeza y cuello y para cirujanos plásticos que realizan cirugías de injerto muscular.
Social Psychology Meets School Mathematics in PISA 2012: An Application of the Theory of Planned Behaviour in Australia  [PDF]

Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.813137
Abstract: Educators and government administrators are keen to find interventions to change the rapidly declining enrollments in senior high school mathematics. In 2012, PISA introduced measures to examine the Theory of Planned Behaviour (TPB), a prominent theory from social psychology for encouraging changes in behavior (and perhaps mathematics enrollments). This paper sought to examine the applicability of the TPB for predicting the relationship between students’ intentions, their mathematics attitudes, subject norms, perceived controllability and self-efficacy as well as their mathematics behaviour, using items created by PISA 2012 question designers to assess these TPB constructs. Australian PISA 2012 data from 14,481 students found that the hypothesized TPB antecedents for studying mathematics were very poor predictors of mathematical intentions and indirectly, weak predictors of mathematical behaviour. The Attitudes factor i.e. an interest in mathematics, was found to be the strongest predictor of mathematical intentions. The poor predictive capacity of the TPB was proposed to have been due to ill-defined indicator items in the PISA 2012 measuring instruments, which did not comply with the TPB’s principles of compatibility and aggregation. Future studies testing the TPB in the context of studying mathematics would benefit from undertaking Elicitation studies to identify appropriate TPB antecedents and indicators of the mathematics behaviour being targeted.
Enhancement of basolateral amygdaloid neuronal dendritic arborization following Bacopa monniera extract treatment in adult rats
Vollala, Venkata Ramana;Upadhya, Subramanya;Nayak, Satheesha;
Clinics , 2011, DOI: 10.1590/S1807-59322011000400023
Abstract: objective: in the ancient indian system of medicine, ayurveda, bacopa monniera is classified as medhya rasayana, which includes medicinal plants that rejuvenate intellect and memory. here, we investigated the effect of a standardized extract of bacopa monniera on the dendritic morphology of neurons in the basolateral amygdala, a region that is concerned with learning and memory. methods: the present study was conducted on 21/2-month-old wistar rats. the rats were divided into 2-, 4- and 6-week treatment groups. rats in each of these groups were further divided into 20 mg/kg, 40 mg/kg and 80 mg/kg dose groups (n = 8 for each dose). after the treatment period, treated rats and age-matched control rats were subjected to spatial learning (t-maze) and passive avoidance tests. subsequently, these rats were killed by decapitation, the brains were removed, and the amygdaloid neurons were impregnated with silver nitrate (golgi staining). basolateral amygdaloid neurons were traced using camera lucida, and dendritic branching points (a measure of dendritic arborization) and dendritic intersections (a measure of dendritic length) were quantified. these data were compared with the data from the age-matched control rats. results: the results showed an improvement in spatial learning performance and enhanced memory retention in rats treated with bacopa monniera extract. furthermore, a significant increase in dendritic length and the number of dendritic branching points was observed along the length of the dendrites of the basolateral amygdaloid neurons of rats treated with 40 mg/kg and 80 mg/kg of bacopa monniera (bm) for longer periods of time (i.e., 4 and 6 weeks). conclusion: we conclude that constituents present in bacopa monniera extract have neuronal dendritic growth-stimulating properties.

Abstract: Anterior cerebral artery is the smaller terminal branch of the internal carotid artery. It is one of the arteries involved in the formation of the arterial circle of Willis at the base of the brain. Its hypoplasia or absence can cause serious problems during neurosurgery or in the vascular dynamics of the brain. We found a rare variation of the right anterior cerebral artery during the dissection of the brain. The initial segment of the artery was hypoplastic and plexiform. The anterior communicating artery was absent. The right and left anterior cerebral arteries fused with each other for a distance of about 1 cm. The course, size and distribution of the distal part of the right anterior cerebral artery were normal. This case may be of special importance to neurosurgeonsand radiologists. Obstructionor rupture of the left anterior
cerebral artery in such cases might result in infarct of the medial surfaces of both cerebral hemispheres.
Anomalous origin and vulnerable course of left colic artery in relation to the pancreas—A case report  [PDF]

Abstract: We report here an anomalous origin and course of left colic artery in relation to pancreas during routine dissection of the abdominal region in a 70-year-old male cadaver in the department of anatomy. The anomalous left colic artery took its origin from the superior mesenteric artery and immediately divided into right and left branches. The right branch passed through the transverse mesocolon to supply the left one third of the transverse colon. The left branch traversed to the left along the inferior border of the body of the pancreas and crossed the left kidney before supplying the left colic flexure of colon and descending colon. This aberrant course of the left branch of the left colic artery can be considered as a “vulnerable” course as it is liable to injury during pancreatic and renal surgeries since the artery is not expected to run along the inferior border of the pancreas. The pancreas, a retroperitoneal organ, is related to major arteries such as abdominal aorta, inferior vena cava, coeliac trunk and its main branches, superior mesenteric vessels, splenic and portal veins. Surgery of the pancreas therefore, not only needs a thorough knowledge of the normal course of branches of these vessels but also demands a good knowledge of possible anomalous vessels arising in this region.
