Fertilization and Implantation in human
Fertilization and Implantation in human samer kareem 3,120 Views • 2 years ago

Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.

Chronic obstructive pulmonary disease (COPD) is defined as progressive, chronic airflow obstruction due to chronic bronchitis, emphysema, or both. The majority of patients have components of both, although one of these entities will frequently dominate the clinical picture. Emphysema�airspace enlargement distal to the terminal bronchioles due to destruction of alveolar septa. Chronic bronchitis�chronic airway inflammation and bronchospasm. Clinically defined as productive cough lasting for at least 3 mo over 2 consecutive years. Although COPD is irreversible, patients with acute exacerbations do have reversible bronchospastic and inflammatory components.

Chest Gunshot
Chest Gunshot samer kareem 25,913 Views • 2 years ago

Gunshot wounds have become increasing common in urban cities and many such cases can lead to undesirable outcomes. While gunshot wounds to the head are considered most lethal, gunshot wounds to the chest too may be dangerous. Gunshot wound to the chest is challenging owing to the presence of vital organs like lungs, heart and their surrounding structures including major blood vessels. Gunshot wound is caused by penetration of the bullet, which travels through a projectile path after being shot from a firearm. The bullet, on hitting the chest, punctures the tissue it first encounters with, the bones or the muscular chest wall. The extent and severity of the injury depends on the characteristics of the bullet and the firearm, the position and the distance of the victim, the projectile path and the nature of the tissue penetrated.

Ureteral Stenting
Ureteral Stenting samer kareem 3,380 Views • 2 years ago

Ureteral stents are one of the most common devices used by urologists. They are placed with cystoscopic guidance in an operating room setting. Ureteral stents are used to relieve ureteral obstruction, promote ureteral healing following surgery, and to assist with ureteral identification during pelvic surgery. Ureteral stent placement is associated with some degree of morbidity in the majority of patients that ranges from generalized urinary discomfort to urinary tract infection or obstruction. Much of the morbidity is related to the biocompatibility of the materials used to fashion the stent and, to some extent, their design; unfortunately, the ideal stent has yet to be discovered.

If you have been diagnosed with a bulging disc, you are not alone. Bulging discs, also known as a disc protrusion, are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root or the spinal cord. As we age, the outer fibrous portion of our discs can weaken. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. If left untreated, the disc can continue to bulge until it tears, which is classified as a herniated disc.
