The gradual curves of the human spine allow the body to absorb many shocks and stresses in daily life. It’s a delicate balance, though, and if part of the spine curves too much, pain and limited mobility may result.

The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.

The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired area along the attached margin of falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses.

Cerebral palsy refers to brain damage that occurs before a child is five years old. Therefore, adults cannot develop cerebral palsy. However, cerebral palsy does not get better or worse with age, so when a child has the condition, he or she will continue to have the condition into adulthood.

In developing countries, domestic animals (eg, dogs) are common sources of infection. In the United States, bats and wild animals (eg, raccoons) are the most common reservoirs of infection. The acquisition of rabies from bats can occur from an unrecognized bite or a scratch, and possibly by inhalation of aerosolized viral particles. Bats are found in all states except Hawaii, and spelunking (cave exploration) is a risk factor for rabies acquisition from bats.

Exo-Glove Poly (Seoul National University). This wearable robot helps disabled patients regain control of their hands.

Encopresis is a problem that children age four or older can develop due to chronic (long-term) constipation. With constipation, children have fewer bowel movements than normal, and the bowel movements they do have can be hard, dry, and difficult to pass. The child may avoid using the bathroom to avoid discomfort.

An antecedent upper respiratory infection is present in 50% of patients. Abdominal pain is a presenting symptom in 1 0-15% of patients. The skin lesions are symmetric, involve dependent parts of the body, and classically progress from an erythematous, macular rash to papular purpura. The joints and kidneys are also commonly involved

-The management of diaper rash includes frequent changing of diapers, avoiding tight-fitting diapers, exposing the skin to air, using diapers with super absorbent surfaces, and applying barrier creams such as zinc oxide or petrolatum.

Orgasm is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic muscular contractions in the pelvic region characterized by sexual pleasure

Capsaicin binds to pain receptors on our nerves called TRPV1. Normally, it reacts to heat by sending warning signals to the brain. Capsaicin causes TRPV1 to send those same signals. So, you react as if there's something hot in your mouth

Definition. The principal signs of cerebellar dysfunction are the following: Ataxia: unsteadiness or incoordination of limbs, posture, and gait. A disorder of the control of force and timing of movements leading to abnormalities of speed, range, rhythm, starting, and stopping.

Idiopathic Hypoproteinemia or Intestinal Lymphangiectasia is a malabsorption disease due to abnormalities of the lymph vessels.

While an anal abscess is an infection within one or more of the anal spaces, an anal fistula (Choice B) is a tunneling between the anus or rectum and another epithelial lined space (eg, the skin overlying the drainage site). Fifty percent of patients with anal abscesses will go on to develop a chronic fistula from the involved anal gland to the overlying skin. Patients with fistulas typically present with an anal abscess that persists after incision and drainage, or with a pustule-like lesion in the perianal or ischiorectal area that continually drains. Surgical repair is usually necessary to eliminate the fistula while preserving fecal continence.

This is a surgical video demonstrating the release and skin grafting of the middle and ring fingers. It demonstrates the marking, dissection, and repair of the fingers.

This medical animation illustrates how acute myeloid leukemia (AML), the most common type of cancer in adults, develops in the blood and bone marrow. The narrator also discusses the symptoms of AML and AML treatment options.
