Rotifer Rotifera Fossil range: Eocene - Recent Rotaria Rotaria Scientific classification Domain: Eukarya Kingdom: Animalia Subkingdom: Eumetazoa Superphylum: Platyzoa Phylum: Rotifera Cuvier, 1798 Classes Monogononta Digononta Seisonidea The rotifers, or rotifaers, make up a phylum of microscopic and near-microscopic pseudocoelomate animals. They were first described by Rev. John Harris in 1696 and other forms were described by Anton van Leeuwenhoek in 1703.[1] Most rotifers are around 0.1-0.5 mm long (although their size can range from 50μm to over 2 millimeters) [2], and are common in freshwater environments throughout the world with a few sal***er species. Some rotifers are free swimming and truly planktonic, others move by inchworming along the substrate, and some are sessile, living inside tubes or gelatinous holdfasts that are attached to a substrate. About 25 species are colonial (eg, Sinantherina semibullata), either sessile or planktonic. Rotifers play an important part of the freshwater zooplankton, being a major foodsource and with many species also contributing to decompositioning of soil.

sessile sessile is a colony of 50 kinetic but non-motile pods that respond to changes in ambient light levels. Although pods share a simple, common morphology each reacts to environmental change in subtly different and often surprising ways.

Ciliates A collection of sessile (fixed to something) ciliates. These are single celled organisms that attach to twigs, rocks etc in the aquatic environment and feed by sweeping food particles from the water with beating, hair-like cilia. These are all freshwater species. Despite being sessile they are surprisingly active. Species include: Vorticella (0:12 & 1:16), Stentor (0:50), Vaginicola (1:00). Some clips are faster than normal speed.

Vaginal Scan - Endometrial Polyp Enviado por " CONSULTORIO MÉDICO JAVIER FLORES BUISSON " MÁNCORA- PERÚ... URL: consultoriomedicofloresmancora.es.tl ... An endometrial polyp or uterine polyp is a sessile mass in the inner lining of the uterus. They may have a large flat base (sessile) or be attached to the uterus by an elongated pedicle (pedunculated).Pedunculated polyps are more common than sessile ones.They range in size from a few millimeters to several centimeters. If pedunculated, they can protrude through the cervix into the vagina.Small blood vessels may be present, particularly in large polyps. Cause and symptoms: No definitive cause of endometrial polyps is known, but they appear to be affected by hormone levels and grow in response to circulating estrogen.They often cause no symptoms. Where they occur, symptoms include irregular menstrual bleeding, bleeding between menstrual periods, excessively heavy menstrual bleeding (menorrhagia), and vaginal bleeding after menopause.Bleeding from the blood vessels of the polyp contributes to an increase of blood loss during menstruation and blood "spotting" between menstrual periods, or after menopause. If the polyp protrudes through the cervix into the vagina, pain (dysmenorrhea) may result. Diagnosis: Endometrial polyps can be detected by vaginal ultrasound (sonohysterography), hysteroscopy and dilation and tection by ultrasonography can be difficult, particularly when there is endometrial hyperplasia (excessive thickening of the endometrium ...

Vocal Fold Polyp Part I: Intraoperative Assessment Examination under anaesthesia (EUA) is an important step prior to diagnostic or therapeutic intervention of a laryngeal lesion. This is aided by the advancement in high power microscopy and endoscopic technology which allows its detail anatomy to be visually ***ysed. Assessment of a vocal fold polyp includes its general appearance, site and extent of involvement, pedicle attachment (sessile of pedunculated), vessel feeder (if obvious), and presence of opposite vocal fold reaction (usually mild thickening). Additional palpation by using microsurgical probing instrument is usually performed to find out thickened or scarred areas. This video shows a benign (non-cancerous) double-headed right vocal fold polyp with a relatively sessile base. There was thickened epithelium surrounding its base best seen when the polyp lifted upward. Vocal fold spreader and triangular forceps were used for assessment of the vocal fold polyp in this patient.

Playing PACMAN with a water droplet Video from "Remote control of moving sessile droplets," by Xavier Noblin, Richard Kofman, Franck Celestini, submitted as part of the Gallery of Fluid Motion 2010 which is showcase of fluid dynamics videos (ArXiv, 18 Oct 2010): "A simple vibrating apparatus can be efficiently used to control the motion of supported droplets. The combined vertical and horizontal vibrations can induce a controlled motion of a sessile supported (water) drop. The vibration frequencies are the same in x, y, z directions, and fixed here to 70 Hz. The drop is of order one millimeter in radius. The liquid is pure water or fluorescein solution. The substrate is made of a piece of PDMS elastomer. The motion of a supported water droplet is remotely controlled using a joystick. Both up, down, right and left motions are controlled. The substrate is made of a PDMS elastomer and the water droplet has an equilibrium wetting angle around 100 degrees. It is possible to drive the droplet to a target deposited on the substrate. The target is a dye powder (fluorescein) deposited on the upper right of the substrate. Note that the used of vibrations enhanced the mixing of the powder within the droplet. PACMAN: The game for the big drop, is to eat the other small droplets."
