Human ovulation captured on film

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.

Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause, primarily occurring in older adults, limited to the lungs, and associated with the histopathologic and/or radiologic pattern of usual interstitial pneumonia (UIP).[1] Signs and symptoms The clinical symptoms of idiopathic pulmonary fibrosis are nonspecific and can be shared with many pulmonary and cardiac diseases. Most patients present with a gradual onset (often >6 mo) of exertional dyspnea and/or a nonproductive cough. Approximately 5% of patients have no presenting symptoms when idiopathic pulmonary fibrosis is serendipitously diagnosed.

Dilation And Curettage Uterus samer kareem 14,623 Views • 2 years ago

Dilation and curettage (D&C) is a procedure to remove tissue from inside your uterus. Doctors perform dilation and curettage to diagnose and treat certain uterine conditions — such as heavy bleeding — or to clear the uterine lining after a miscarriage or abortion. In a dilation and curettage — sometimes spelled "dilatation" and curettage — your doctor uses small instruments or a medication to open (dilate) your cervix — the lower, narrow part of your uterus. Your doctor then uses a surgical instrument called a curette to remove uterine tissue. Curettes used in a D&C can be sharp or use suction

Blood Viscosity
Blood Viscosity samer kareem 1,362 Views • 2 years ago

When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

Tummy tuck is a surgical procedure also known as abdominoplasty to remove excess skin and fat from the middle and lower abdomen and to tighten the muscles of the abdominal wall. The procedure can dramatically reduce the appearance of a protruding abdomen. But bear in mind, it does produce a permanent scar.

What is frontotemporal dementia?
What is frontotemporal dementia? samer kareem 1,898 Views • 2 years ago

Frontotemporal dementia is the name for a range of conditions in which cells in the frontal and temporal lobes of the brain are damaged. These lobes control behaviour, emotional responses and language. This means that people will experience changes in personality and behaviour, or may struggle with language – for example, in finding the right word. Frontotemporal dementia is a less common form of dementia which is more likely to affect younger people – those under 65.

Vascular dementia
Vascular dementia samer kareem 1,755 Views • 2 years ago

Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain. You can develop vascular dementia after a stroke blocks an artery in your brain, but strokes don't always cause vascular dementia. Whether a stroke affects your thinking and reasoning depends on your stroke's severity and location. Vascular dementia also can result from other conditions that damage blood vessels and reduce circulation, depriving your brain of vital oxygen and nutrients
