HIV Virus Life Cycle and Drug Reaction
HIV Virus Life Cycle and Drug Reaction Magdy 11,486 Views • 3 years ago

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.

Buttocks Gluteal Implants Insertion
Buttocks Gluteal Implants Insertion Scott 46,324 Views • 3 years ago

Butt implants are a popular plastic surgery procedure among those who wish to enhance the appearance, shape, and size of their rear ends. Buttock augmentation involves the surgical insertion of artificial body implants into a patient’s buttocks to create a larger, shapelier, and more sensuous rear end. Patients who have underdeveloped buttocks can achieve a more proportionate figure with butt implants. Women who wish to achieve an “hour glass” figure or are unhappy with the size of their buttocks can benefit from female butt implants. Men with flat or poorly developed buttocks can enhance the shape of the area to their liking with male butt implants. Many buttock augmentation patients say that their clothes fit better, they feel more attractive, and their confidence levels have improved.

Transurethral Prostatectomy TURP
Transurethral Prostatectomy TURP Scott 235,041 Views • 3 years ago

Transurethral resection of the prostate (also known as TURP, plural TURPs and as a transurethral prostatic resection TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. This is considered the most effective treatment for BPH. This procedure is done with spinal or general anesthetic. A large triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80-90% of BPH patients. Because of bleeding risks associated with the surgery, TURP is not considered safe for many patients with cardiac problems. As with all invasive procedures, the patient should first discuss medications they are taking with their doctor, most especially blood thinners or anticoagulants, such as warfarin (Coumadin), or aspirin. These may need to be discontinued prior to surgery. Postop complications include bleeding (most common), clotting and hyponatremia (due to bladder irrigation).

Additionally, transurethral resection of the prostate is associated with low but important morbidity and mortality.

Testing for the four features of Gerstmann Syndrome in this patient with two separate left sided strokes (left frontoparietal ischaemic stroke followed by left posterior parietal haemorrhagic stroke). He exhibits (i) acalculia, (ii) agraphia, (iii) left-right disorientation, and (iv) finger agnosia. Complicating the issue is his obvious nonfluent aphasia (expressive dysphasia) with paraphasic errors (replacing words with associated words (e.g. says 'fork' instead of 'spoon')) and some comprehension issues.

A spontaneous vaginal delivery (SVD) occurs when a pregnant woman goes into labor with or without use of drugs or techniques to induce labor, and delivers her baby in the normal manner, without forceps, vacuum extraction, or a cesarean section. Assisted vaginal delivery (AVD) occurs when a pregnant woman goes into labor with or without the use of drugs or techniques to induce labor, and requires the use of special instruments such as forceps or a vacuum extractor to deliver her baby vaginally.

Sporotrichosis (also known as "rose gardener's disease") is a disease caused by the infection of the fungus Sporothrix schenckii. This fungal disease usually affects the skin, although other rare forms can affect the lungs, joints, bones, and even the brain.

SPERMATOCELE vs EPIDIDIMAL CYST
SPERMATOCELE vs EPIDIDIMAL CYST samer kareem 3,105 Views • 3 years ago

The epididymis is a long coiled tube that lies above and behind each testicle. The epididymis collects and transports sperm from the testis to the vas deferens (tubes that transport sperm to the urethra). An epididymal cyst is a cyst-like mass in the epididymis that contains clear fluid. Typically, epididymal cysts and spermatoceles do not cause symptoms. When discovered, the epididymal cyst is usually about the size of a pea and feels separate from the top of the testis. Spermatoceles typically arise from the head of the epididymis, and are felt on the top portion of the testicle. Epididymal cysts and spermatoceles are often incidental findings on testicular self-examination or routine physical examination. It is important that any mass noted in the scrotum be examined by a urologist in order to obtain an accurate diagnosis, especially a mass on the testicle itself. Our team in the Division of Urology will typically be able to confirm the diagnosis on physical exam. However, a scrotal ultrasound may also be used in order to rule out other conditions.

Natural Childbirth
Natural Childbirth samer kareem 4,587 Views • 3 years ago

A natural, unmedicated approach to labor and birth will suit you best if you want to remain in control of your body as much as possible, be an active participant throughout labor, and have minimal routine interventions such as continuous electronic monitoring. If you choose to go this route, you accept the potential for pain and discomfort as part of giving birth. But with the right preparation and support, women often feel empowered and deeply satisfied by natural childbirth.
