Human ovulation captured on film
Human ovulation captured on film Mohamed 27,056 Views • 2 years ago

To record the sequence, Stephan Gordts and Ivo Brosens of the Leuven Institute for Fertility & Embryology in Belgium performed transvaginal laparoscopy, which involves making a small cut in the vaginal wall and observing the ovary with an endoscope.

"This allows us direct access to and observation of the tubo-ovarian structures without manipulation using forceps," says Gordts.

For the photos of ovulation, which only accidentally captured the critical moment, Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium, used gas to distend the organs for photography. However, Gordts and Brosens planned the procedure to coincide with ovulation and used saline solution to "float" the structures.
Perfect timing

Observation was timed for the day of the peak of the patient's luteal hormone cycle. Ovulation was predicted to occur on the evening of the day of the LH peak, and the endoscope introduced at 6 pm.

A small amount of saline was used to float the opening of the fallopian tube, its fimbriae (the "fingers" that sweep the egg into the tube) and the ovary itself. This gives a more natural appearance than gas, says Gordts.

In the video, the fimbriae can be seen sweeping in time with the patient's heartbeat. A mucus plug can be seen protruding from the ovary – this contains the egg.

"The ovum is not captured 'naked'," says Gordts. "There is no eruption like a volcano."

Gordts says that in clinical practice it is not easy to organise the observation of ovulation. "We were probably lucky to be successful at our first attempt," he says.

Muscle Tissues and Sliding Filament Model
Muscle Tissues and Sliding Filament Model DrPhil 163 Views • 2 years ago

Join the Amoeba Sisters a they explore different muscle tissues and then focus on the sliding filament theory in skeletal muscle! This video also briefly talks about muscle naming, some vocabulary (such as agonists and antagonists) before focusing on the sliding filament model. Video also mentions general roles of tropomyosin and troponin.

Laparoscopic Cholecystectomy Full Length Skin to Skin Video with Near Infrared Cholangiography

This video demonstrate Laparoscopic Cholecystectomy Full Length Skin to Skin Video with Infrared Cholangiography performed by Dr R K Mishra at World Laparoscopy Hospital. Infrared Cholegiography is performed by using Indocyanine Green during laparoscopic cholecystectomy surgery for gallbladder removal. Bile duct injury remains the most feared complication of laparoscopic cholecystectomy. Intraoperative cholangiography (IOC) is the current gold standard for biliary imaging and may reduce injury, but is not widely used because of the difficulties of doing it. Near-Infrared Fluorescence Cholangiography (NIRF-C) is a novel non-invasive method for real-time, radiation-free, intra-operative biliary mapping during laparoscopic cholecystectomy. We have experienced that NIRF-C is a safe and effective method for identifying biliary anatomy during laparoscopic cholecystectomy. Indocyanine green is a cyanine dye is very popular and used for many years in medical diagnostics. It is used for determining cardiac output, hepatic function, liver, and gastric blood flow, and for ophthalmic angiography. Now the use of this dye in lap chole has improved the safety of this surgery by NEAR INFRARED FLUORESCENT CHOLANGIOGRAPHY.
