INTRODUCTION Unlike left sided accessory spleen that are seen in 10-30% of cases at autopsy, cases of right accessory spleens are extremely rare. This congenital body of healthy splenic tissue simulates tumors from neighboring organs and presents a challenge in formulating a differential diagnosis. PRESENTATION OF CASE We present the case of a patient whose CT scan of the abdomen showed a lar...

RATIONALE Accessory spleen torsion is a rare cause of the acute abdomen. The complications of accessory spleen torsion, such as intestinal obstruction, are rarer. We herein report a case of colonic obstruction caused by accessory spleen torsion because of the unusual condition. PATIENT CONCERNS A 15-year-old patient presented with acute intestinal obstruction with signs of peritoneal irritati...

BACKGROUND A small accessory facet with articular surface morphology is occasionally seen on the talus, bordering on the lateral end of the sinus tarsi. This facet has been named the accessory anterolateral talar facet. However, few anatomical studies have addressed this facet. Here we present the precise morphology of accessory anterolateral talar facet with emphasis on anatomical correlation ...

C6 cell tubulin is indistinguishable from hog brain tubulin with respect to its molecular weight, amino acid composition, and colchicine-binding activity. Moreover, microtubule assembly systems from both sources form the same structures: rings, ribbons, tubules, and drug-induced polymers. There is, nevertheless, a difference between the cultured cell and brain systems which lies in the nature o...

We present a case of an anomalous accessory iliacus muscle in the iliac fossa which gets originated from the iliac crest and inserting along with iliopsoas, and appear to compress the L4 root of femoral nerve. During the routine dissection of a male cadaver aged 58 years, we found an accessory iliacus muscle. The L2 and L3 nerve roots joined the L4 root distal to the accessory iliacus muscle. T...

Recombinant 1,25-dihydroxyvitamin D3 receptor from a baculovirus expression system requires a mammalian-derived nuclear accessory protein for binding to a vitamin D response element (DRE). This was established by electrophoretic mobility shift analyses using radiolabeled DNA probes consisting of DREs from two vitamin D-responsive genes. Mammalian nuclear extract was also required for the bindin...

Accumulating evidence suggests that the accessory medulla is the location of the circadian pacemaker in the fruit fly Drosophila melanogaster and the cockroach Leucophaea maderae. gamma-Aminobutyric acid (GABA) and Mas-allatotropin are two putative neurotransmitters, in the accessory medulla in the cockroach Leucophaea maderae. Neurons immunoreactive to the neuropeptide Mas-allatotropin are loc...

BACKGROUND More than 10% of healthy population has one or more accessory spleens. The most common location is the hilum of the spleen or area near the tail of the pancreas. The radiological appearance of accessory spleens in oncologic patients who underwent splenectomy can be misinterpreted as a recurrence, especially in the case of compensatory growth of an accessory spleen in successive radio...

Females of most animal species are usually inseminated by more than one male, which allows sperm from different males to compete for fertilization. To prevent invasion of sperm from other males, Drosophila males elicit a rejection behavior in their mates after copulation. Using paired mutant males that, for the lack of accessory glands, are sterile, we show that this rejection behavior is induc...

Catheter ablation for septal accessory pathways is occasionally associated with complications, such as atrioventricular block, since the septal region is a complex anatomical structure containing the atrioventricular conduction system. Therefore, we designed a signal separator composed of an inductance-capacitance network with which the local electrogram at the ablation site could be continuous...
