our uterus (or womb) is normally held in place inside your pelvis with various muscles, tissue, and ligaments. Because of pregnancy, childbirth or difficult labor and delivery, in some women these muscles weaken. Also, as a woman ages and with a natural loss of the hormone estrogen, her uterus can drop into the vaginal canal, causing the condition known as a prolapsed uterus.

Scientists have developed a gene editing technique which targets HIV-1 DNA. Through the technique, scientists successfully edited the virus out the genome in human cells; their study also showed the technique can prevent viral replication in cleared cells. Using CRISPR/Cas9 gene editing, the team tested patient cells grown in a lab which were no longer susceptible to HIV infection.

The bone marrow aspiration is usually done first. The doctor makes a small incision, then inserts a hollow needle through the bone and into the bone marrow. Using a syringe attached to the needle, the doctor withdraws a sample of the liquid portion of the bone marrow. You may feel a brief sharp pain or stinging.

Duodenal atresia, also known as duodenojejunal atresia, is the congenital absence or complete closure of a portion of the lumen of the duodenum. It causes increased levels of amniotic fluid during pregnancy (polyhydramnios) and intestinal obstruction in newborn babies.

With inner ear disorders, your brain receives signals from the inner ear that aren't consistent with what your eyes and sensory nerves are receiving. Vertigo is what results as your brain works to sort out the confusion. These self-help acupressure points works with meridians to help the body regain normal healing and homeostasis.

Knee pain facts Knee pain is a common problem with many causes, from acute injuries to complications of medical conditions. Knee pain can be localized to a specific area of the knee or be diffuse throughout the knee. Knee pain is often accompanied by physical restriction. A thorough physical examination will usually establish the diagnosis of knee pain. The treatment of knee pain depends on the underlying cause. The prognosis of knee pain is usually good although it might require surgery or other interventions.

Schwannomas are usually located in the angle between the cerebellum and the pons, in the back of the skull (the posterior fossa). Description Schwannomas are usually very slow-growing. Symptoms Common symptoms of Schwannoma are one-sided hearing loss and buzzing or ringing in the ear. Dizziness may also occur, although it is less common. If the tumor affects the facial nerve (the 7th cranial nerve, which is located next to the 8th cranial nerve), facial paralysis may occur. Other symptoms include difficulty in swallowing, impaired eye movement, taste disturbances, and unsteadiness. Incidence Schwannomas account for about 8% of all primary brain tumors. They typically occur in middle-aged adults, and females are twice as likely as males to have this tumor. Cause Like many tumor types, the exact cause of Schwannoma is not known. However, it is believed to occur when there is a defect in a gene that normally prevents tumors from forming. Treatment Total removal using microsurgical techniques is often possible. Stereotactic radiosurgery may be used as an alternative to surgery in some patients.

Red blood cells, which form one of the major constituents of blood, are characterized by the absence of nuclei, hence they are unable to undergo cellular division or generate new erythrocytes from old ones. This eventually leads to cell disintegration, which typically occurs 4 months after the fully developed red blood cells have been in circulation within the bloodstream. During the degeneration of the red blood cells, some components of the hemoglobin are excreted from the body while other parts are conserved.

The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (b). Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen.

CPAP is a treatment that uses mild air pressure to keep your breathing airways open. It involves using a CPAP machine that includes a mask or other device that fits over your nose or your nose and mouth, straps to position the mask, a tube that connects the mask to the machine’s motor, and a motor that blows air into the tube. CPAP is used to treat sleep-related breathing disorders including sleep apnea. It also may be used to treat preterm infants who have underdeveloped lungs.

Obesity is one of the most pervasive, chronic diseases in need of new strategies for medical treatment and prevention. As a leading cause of United States mortality, morbidity, disability, healthcare utilization and healthcare costs, the high prevalence of obesity continues to strain the United States healthcare system. Obesity is defined as excess adipose tissue. There are several different methods for determining excess adipose (fat) tissue; the most common being the Body Mass Index (BMI) (see below). A fat cell is an endocrine cell and adipose tissue is an endocrine organ. As such, adipose tissue secretes a number of products, including metabolites, cytokines, lipids, and coagulation factors among others. Significantly, excess adiposity or obesity causes increased levels of circulating fatty acids and inflammation. This can lead to insulin resistance, which in turn can lead to type 2 diabetes.
