An HIV vaccine is a hypothetical vaccine against HIV, the etiological agent of AIDS. As there is no known cure for AIDS, the search for a vaccine has become part of the struggle against the disease.
The urgency of the search for a vaccine against HIV stems from the AIDS-related death toll of over 25 million people since 1981.[1] Indeed, in 2002, AIDS became the primary cause of mortality due to an infectious agent in Africa (UNAIDS, 2004).
Migraine is a neurological syndrome characterized by altered bodily experiences, painful headaches, and nausea. It is a common condition which affects women more frequently than men.
The typical migraine headache is one-sided and pulsating, lasting 4 to 72 hours. Accompanying complaints are nausea and vomiting, and a heightened sensitivity to bright lights (photophobia) and noise (hyperacusis).Approximately one third of people who experience migraines get a preceding aura, in which a patient may sense a strange light or unpleasant smell.
The first anesthesia (a herbal remedy) was administered in prehistory. Opium poppy capsules were collected in 4200 BC, and opium poppies were farmed in Sumeria and succeeding empires. The use of opium-like preparations in anaesthesia is recorded in the Ebers Papyrus of 1500 BC. By 1100 BC poppies were scored for opium collection in Cyprus by methods similar to those used in the present day, and simple apparatus for smoking of opium were found in a Minoan temple. Opium was not introduced to India and China until 330 BC and 600–1200 AD respectively, but these nations pioneered the use of cannabis incense and aconitum.
Otitis media is inflammation of the middle ear, or middle ear infection (the word otitis is Greek and it means “inflammation of the ear”, and media means middle).
Otitis media occurs in the area between the ear drum (the end of the outer ear) and the inner ear, including a duct known as the Eustachian tube. It is one of the two categories of ear inflammation that can underly what is commonly called an earache, the other being otitis externa. Diseases other than ear infections can also cause ear pain, including cancers of any structure that shares nerve supply with the ear.
The Chinese Classification of Mental Disorders (CCMD), published by the Chinese Society of Psychiatry (CSP), is a clinical guide used in China for the diagnosis of mental disorders. It is currently on a third version, the CCMD-3, written in Chinese and English. It is intentionally similar in structure and categorisation to the ICD and DSM, the two most well-known diagnostic manuals, though includes some variations on their main diagnoses and around 40 culturally-related diagnoses.
