Spermatogenesis

Spermatogenesis is the process in which spermatozoa are produced from spermatogonial stem cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis.

It then spreads down the bundle of his and then purkinje fibres to cause ventricular contraction. So when viewing the heart from the front, the direction of depolarisation is 11 o'clock to 5 o'clock. The general direction of depolarisation is known as the cardiac axis.

Edwards Syndrome
Edwards Syndrome samer kareem 3,956 Views • 3 years ago

Trisomy 18, also called Edwards syndrome, is a chromosomal condition associated with abnormalities in many parts of the body. Individuals with trisomy 18 often have slow growth before birth (intrauterine growth retardation) and a low birth weight. Affected individuals may have heart defects and abnormalities of other organs that develop before birth. Other features of trisomy 18 include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers. Due to the presence of several life-threatening medical problems, many individuals with trisomy 18 die before birth or within their first month. Five to 10 percent of children with this condition live past their first year, and these children often have severe intellectual disability.

Pompe Disease
Pompe Disease samer kareem 4,108 Views • 3 years ago

Pompe disease is a rare multisystem genetic disorder that is characterized by absence or deficiency of the lysosomal enzyme alpha-glucosidase (GAA). This enzyme is required to breakdown (metabolize) the complex carbohydrate glycogen and convert it into the simple sugar glucose.

Meckel's Diverticulum
Meckel's Diverticulum samer kareem 5,847 Views • 3 years ago

The differential diagnosis for this child's painless hematochezia includes Meckel's diverticulum as well as vascular malformations. Meckel's diverticulum results from a failure of the vitelline duct to obliterate during the first 8 weeks of gestation, leaving behind a blind pouch often containing ectopic gastric tissue. Meckel's diverticulum classically affects children age ~:2 but can also occur in older children or even adults. Young children are more likely to experience painless bleeding due to mucosal irritation from gastric acid; adolescents and adults are more likely to have signs of obstruction. A technetium-99 nuclear scan will identify the diverticulum, which is usually located in the right lower quadrant of the abdomen within 2 feet of the ileocecal valve. Technetium-99 concentrates in the parietal cells of the diverticulum and stomach. The scan is also known as "Meckel's scan" due to its high specificity. A symptomatic Meckel's diverticulum is generally treated with surgical resection.

-Traumatic amputation of a body part requires rapid transport of the appendage, which should be wrapped in a saline-moistened gauze, placed in a plastic bag, and transported in a container filled with ice mixed with either saline or sterile water to best preserve the body part and attempt replantation.

The Importance of Correcting your Overbite
The Importance of Correcting your Overbite samer kareem 9,892 Views • 3 years ago

Overbite is a type or malocclusion or an overjet. A lot of people don’t realize that they have an overbite, as they believe their condition is not serious enough to obtain dental attention. This could also for the reason that other cases of overbites are so minor to be noticeable. However, others have serious overbite condition that can make the person’s top jaw look much larger or the bottom jaw significantly smaller. But one thing to remember, overbite can actually cause some dental problems. This condition can change the structure of your face and affect the way you talk. The most popular form of overbite correction is orthodontic treatment. Your dentist will fix the overbite with the help of rubber bands and dental braces to pull the upper teeth back. Tooth extraction may be suggested if overcrowding complicates the overbite so as to provide room for your front teeth. In extreme conditions, overbite surgery may be needed to place your jaw backwards or forwards. Furthermore, if severe overbite is not corrected during adulthood, the teeth may continue to shift and trigger dental issues such as gum disease.

Here is how surgeons perform knock knee correction surgery. Titanium plate is used to stabilize the affected area. The femur is cut nearly through to help with the stability. Spreaders angle the cut align the leg. The plate is secured with several screws. Synthetic bone graft material is packed in the joint. The patient will be in crutches for 4 to 6 weeks.

At first, grasping the needle is difficult because it will have a tendency to want to jump around. What can oftentimes help is to get hold of the thread with the left-hand forceps at a point 2 to 3 cm away from the needle. Dangle the needle until it just comes to rest on the surface. This will then allow you to use the angulated needle holder to grab the needle easily. Your needle is in a stable position if it is set up to 90 degrees to the axis of the tips of the forceps. You can make minor corrections by touching the needle with your left-hand forceps, or by partially relaxing your grip and nudging the needle tip against another firm object. You should hold the needle just behind its midpoint (If you hold it too near the tip, it will point downward. If you hold it too near the thread end, it will point upward.).

Minimally invasive plate osteosynthesis in the treatment of the femoral shaft fracture
Minimally invasive plate osteosynthesis in the treatment of the femoral shaft fracture samer kareem 1,247 Views • 3 years ago

Our results in this study of MIPO treated with conventional plates are comparable to the results of the femoral shaft fractures treated with intramedullary nailing. The technique can be used for all femoral shaft fractures. Although the biomechanics of the plate fixation are less stable compared to the intamedullary nail, the mechanical stability is stable enough for bone healing. Healing was rapid, and postoperative care was simplified. The two major complications were malalignment and screw breakage. We recommend using at least three separated screws in each fragment to prevent stress on the screw and screw breakage. Intraoperative limb length, axial alignment, and rotation must be carefully assessed to prevent malalignment. The limitations of our study include lack of a comparison group, retrospective data collection, and no randomisation in outcome evaluation
