introduction: hanging is one of the most commonly used way to commit suicide in many countries. this method used in suicide is considered a problem in iran too, but no clear data exists regarding hanging in different regions or the country as a whole. because of the epidemiologic differences in non-judicial hanging in different regions, this study aimed to assess it in gilan province, iran betw...

The Mediterranean sponge Aplysina aerophoba kept in aquaria or cultivation tanks can stop pumping for several hours or even days. To investigate changes in the chemical microenvironments, we measured oxygen profiles over the surface and into the tissue of pumping and non-pumping A. aerophoba specimens with Clark-type oxygen microelectrodes (tip diameters 18-30 μm). Total oxygen consumption rate...

This is the second paper in a series of works devoted to nonholonomic Ricci flows. By imposing non–integrable (nonholonomic) constraints on the Ricci flows of Riemannian metrics we can model mutual transforms of generalized Finsler–Lagrange and Riemann geometries. We verify some assertions made in the first partner paper and develop a formal scheme in which the geometric constructions with Ricc...

Porifera (sponges) are the most basal phylum of extant metazoans. To gain insight into sponge genome construction, cytogenetic analysis was performed for ten freshwater sponge species of six genera, using conventional Giemsa staining, chromosome banding, and fluorescence in-situ hybridization. The karyotypes were very similar among the ten species, exhibiting a diploid chromosome number of 2n=4...

Controlling the concentration of drugs in pharmaceutical products is essential to patient's safety. In this study, a simple and sensitive HPLC method is developed to quantitatively analyze capsaicin in collagen sponge. The capsaicin from sponge was extracted for 30 min with ultrasonic wave extraction technique and methanol was used as solvent. The chromatographic method was performed by using i...

BACKGROUND Marine sponge is a rich natural resource of many pharmacologically important compounds. OBJECTIVE Marine sponge Hyrtios erectus, collected from North Bay, South Andaman Sea, India, was screened for potential antiproliferative and proapoptotic properties on a breast adenocarcinoma cell line (MCF-7). MATERIALS AND METHODS 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide...

This study examined the recruitment of host cells into a progressing EMT6 tumor following the inoculation of tumorigenic cells into a preimplanted gelatin sponge. Tumor cell proliferation occurred to a greater extent in sponge tumors than in tumors obtained by direct subcutaneous injection of tumor cells. Blank sponges, lacking tumorigenic cells and used as controls, elicited an inflammatory re...

This study aimed at describing demographic information of the deceased resulting from hanging by means of different methods of suicide. In this cross-sectional study, the file of suicide cases referred to the Central Legal Medicine Organization was investigated retrospectively. Of 1681 suicide cases, the highest suicide mode was hanging by 993 cases (57.4%) and intoxication by 674 cases (39%). ...
