If there is something that we all know about in the 21st century it is stress, whether it's the stress of work, financial stress or the stress of getting the next grant funded; we are all familiar with that heart-pounding, race-against-time feeling. But this is a very modern perspective on stress. As far as physiologists are concerned, stress is a well-known factor that has driven evolution and moulded the planet's ecosystems since life began. 'Stress is a hot topic', says Shireen Davies,...

Why Some Wound Infections Become Chronic Explained By Researchers

University of California - Riverside UC Riverside's Manuela Martins-Green shows how decreasing levels of 'reactive oxygen species' can break cycle of unhealing wounds Chronic wounds affect an estimated 6.5 million Americans at an annual cost of about $25 billion. Further, foot blisters and other diabetic ulcers or sores account for the vast majority of foot and leg amputations in the United States today. Why does treating chronic wounds cost so much? What complicates chronic wound...

The University of Geneva, Switzerland, has generated UV-resistant transgenic plants which produce high levels of antioxidants Plants have a love-hate relationship with sunlight. While some wavelengths are indispensable to them for performing photosynthesis, others, such as UV-B, are deleterious. Therefore, plants are equipped to detect these highly toxic rays and mount their defenses. A team led by Roman Ulm, Professor at the Faculty of Sciences at the University of Geneva (UNIGE),...

Temperature Examination
2012-11-26 23:06:36

Taking a patient's temperature is an initial part of a full clinical examination. The moment the medical provider comes within inches of the patient’s skin, they can tell if there is a change in the patient’s temperature. Heat radiates from a febrile patient, skin becomes clammy when cardiac output is reduced, and cold skin can be an ominous sign when combined with other negative findings. Temperature is an important indicator for patient status. How the Temperature is Attained...

The cricothyroid ligament makes up the largest part of the laryngeal membrane, consisting of a median (anterior) and twin lateral ligaments. The median cricothyroid ligament is a flat band of white tissue joining the cricoid and thyroid cartilages. The lateral cricothyroid ligament is also known as the conus elasticus. The main function of the ligament is to keep the cricoid and thyroid from traveling too far. This ligament is cut during emergency cricothyrotomy. Image Caption: Larynx -...

Biology is the study of living organisms. Before the 19th century, biology was known as natural history (the study of all living things). Gottfried Reinhold Treviranus was the first person to coin the term biology. Biology comes from the Greek words bios (meaning "life") and logia (meaning "study of"). It is a common science that is a standard subject in schools and universities around the world. Over a million papers are published annually in biology and medicinal journals. Not just a...

The Electric eel, Electrophorus electricus, is a species of fish. It is capable of generating powerful electric shocks, which it uses for both hunting and self-defense. It is a top predator in its South American range. Despite its name it is not an eel at all but rather a knifefish. Taxonomy The species is so unusual that it has been reclassified several times. Originally it was given its own family Electrophoridae, and then placed to a genus of Gymnotidae alongside Gymnotus....
