Sigmoid colon is one of the most variable parts of the large intestine. Here we report a very rare type of variation of the sigmoid colon. This variation was observed during the routine dissections for undergraduate medical students at Melaka Manipal Medical College (Manipal Campus) India in September 2012. In the current case, the sigmoid colon was about 60 cms long and made an inverted U shap...

Vegetation models based on multiple logistic regression are of growing interest in environmental studies and decision making. The relatively simple sigmoid Gaussian optimum curves are most common in current vegetation models, although several different other response shapes are known. However, improvements in the technical means for handling statistical data now facilitate fast and interactive ...

The current study investigates the electrosigmoidographic (ESG) patterns in 50 patients with sigmoid colon pathologies and 10 healthy controls. Three electrodes were applied to the skin of the lower abdomen and the reference electrode was placed on the lower limb. Ulcerative colitis patients showed a "tachyarrhythmic" ESG; the PPs had a higher frequency with a lower amplitude and velocity than ...

BACKGROUND HIV-1 drug resistance can be measured with phenotypic drug-resistance tests. However, the output of these tests, the resistance factor (RF), requires interpretation with respect to the in vivo activity of the tested variant. Specifically, the dynamic range of the RF for each drug has to be divided into a suitable number of clinically meaningful intervals. METHODS We calculated a su...

The gain of neurons’ responses in the auditory cortex is sensitive to contrast changes in the stimulus within a spectrotemporal range similar to their receptive fields (Rabinowitz et al., 2012), which can be interpreted to represent the tuning of the input to a neuron. This indicates a local mechanism of contrast gain control, which we explore with a minimal mechanistic model here. Gain control...

actinomycosis is a rare and chronic infectious disease caused by a non-spore gram- positive, anaerobic bacterium that rarely infects the colon, in particular the left colon. a 53-year-old woman was referred to us due to chronic abdominal pain, bloating, a few episodes of bloody-mucous rectal discharge, and  change of bowel habits. her medical history and physical examination were unremarkable. ...

AIMS Studies in animals and patients indicate that rapamycin affects vasodilatation differently in outer and inner curvatures of blood vessels. We evaluated in this study whether rapamycin affects endothelial nitric oxide synthase (eNOS) responsiveness to shear stress under normo- and hypercholesteraemic conditions to explain these findings. METHODS AND RESULTS Shear stress levels were varied...

We determined the power and its graph simulations on discrete Poisson Chi-square distributions. There are four important steps of research methodology summarized as follow: (1) determine sufficient statistics (if possible), (2) create rejection area (UMPT test is sometime used), (3) derive formula power, (4) graphs using data (in simulation). The their curves then created <img src=image/1342768...

BACKGROUND AND PURPOSE Bone wax is a hemostatic agent that has been reported in some instances to migrate into the sigmoid sinus following posterior fossa surgery. The purpose of this study was to characterize the CT and MR imaging findings of this entity. MATERIALS AND METHODS The study included 212 consecutive patients who underwent posterior fossa surgery and postoperative CT and contrast-...
