Coleps are common freshwater ciliated Prostomatea with barrel-shaped bodies, usually less than 100 micrometers long. They prey on a variety of aquatic organisms, including fish eggs and larva. Here we are showing them voraciously feeding from a dead zebrafish embryo. With its sharp teeth and its rapid revolution, they are able to kill and eat baby (4-7 day old) zebrafish (Mazanec, A. & Trevarrow, B., 1998). We found that they can make quickly disappear entire baby zebrafish stocks.

Interview with Dr. Richard L. Heaton from the Heart of Georgia Women's Center, Warner Robins, GA
Bowel bags are transparent sterile plastic bags that had no practical application in gynecology. In this video we describe the bowel bag isolation technique used in cases of large pelvic masses, solid and cystic, that are felt to be at a low but real risk of malignancy. This technique protects the peritoneal cavity from contamination with malignant cells during morcellation or cyst rupturing.

A collection of chest x-rays in pleural effusion. The spectrum range from imaging findings in classical moderate to massive pleural effusion to findings in small loculated effusion. Pleural effusion was confirmed with ultrasound or CT-thorax in all of them.
Heart beating in the abdominal wall defect (epigastrium). The components of Pentology of Cantrell are abdominal wall defect, diaphragmatic defect, sternal cleft, pericardial defect, and intracardiac anomaly.
The video successfully demonstrates all the stages of peristalsis visible in the epigastrium as characterized by the patients of pyloric stenosis.
Clonus is defined as recurrent uninhibited contraction of a skeletal muscle [ often a group of muscles ] to persistent stretch. This may result due to disease affecting the pyramidal tract and occasionally extra-pyramidal tract. The video shows the classical ankle clonus which is obtained by supporting the leg by holding the upper part of the calf muscle just below popliteal fossa and passive dorsiflexion of the ankle joint. This passive dorsiflexion should be quick and the stretch must be sustained for sometime. The video shows recurrent oscillation of the ankle joint due to persistent contraction of the muscles contributing to achiles tendon [ gastronemius and soleus ] .The quick passive dorsiflexion is maintained for 20 seconds in the video. This patient was suffering from cerebro-vascular accident . Presence of sustained clonus indicates a severe pyramidal tract involvement. An ill sustained clonus for few seconds may occur in anxious patients and those suffering from psychiatric illness.
