Stress in Biological Definition

Apoptosis

... 1.1 Cell damage or infection 1.2 Response to stress or DNA damage 1.3 Homeostasis 1.4 ... of cervical cancer . Response to stress or DNA damage stress conditions (such as starvation) as well as damage ...

Biomechanics

... components. Commonly used second order tensors include the Cauchy stress tensor, the second Piola-Kirchhoff stress tensor, the deformation gradient tensor, and the Green strain tensor. A ...

Insulin

... from cellular stores. The release of insulin is strongly inhibited by the stress hormone adrenalin (epinephrine). Signal transduction There are ... type, and timing to fit other conditions as for instance the increased stress of illness the dosage is non-physiologic in that a subcutaneous bolus ...

Lambda phage

... is expressed in that state codes for proteins that look out for signs of stress in the host cell. stress can be a result of starvation, poisons (like antibiotics), and other ...

Anabolism

... These processes involve "dismantling" of structural proteins for recycling for other purposes. Catabolic processes occur during starvation , stress and illness. Examples of catabolic processes include breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis ...

Biodiversity

... are important for ecosystem function and human survival. Research suggests that a more diverse an ecosystem is better able withstand environmental stress and consequently is more productive. The loss of a species is thus likely to decreases the ability of the system to maintain itself or to recover ...

Bioinformatics

... form hypotheses about the genes involved in each state. In a single-cell organism, one might compare stages of the cell cycle , along with various stress conditions (heat shock, starvation, etc.). One can then apply clustering algorithms to that expression data to determine which genes are ...

Bone

... and occurs throughout a person's life. Its purpose is the release of calcium and the repair of micro-damaged bones (from everyday stress). Repeated stress results in the bone thickening at the points of maximum stress. It has been hypothesized that this is a result of bone's piezoelectric properties, ...

Brain

... stem cell research may offer a cure. Mental illnesses , such as clinical depression , schizophrenia , bipolar disorder , and post-traumatic stress disorder , are now recognized as having a biological basis in the brain. These disease can be treated by psychiatric therapy , by drugs , or by a ...

Cancer

... are a good place to start looking. While some people are reluctant to seek counseling, studies show that having someone to talk to reduces stress and helps people both mentally and physically. Counseling can also provide emotional support to cancer patients and help them better understand their ...

Down syndrome

Homeostasis

... the tendency of a population or an individual to stay at a certain level of stress, often generating artificial stresses if the "natural" level of stress is not enough. Examples Thermal regulation : The skeletal muscles can shiver to produce heat if the body temperature is too low. ...

Kwashiorkor

... , albumin , vitamin E and polyunsaturated fatty acids. Therefore, if a child with reduced type I nutrients or anti-oxidants is exposed to stress (e.g. an infection or toxin) he/she is more liable to develop kwashiorkor. ...

Natural selection

... What makes one trait more likely to succeed is highly dependent on environmental factors, including the species' predators, food sources, abiotic stress , physical environment, and so on. When members of a species become separated, such as geographically, they face different environments, and tend to ...

Pentose phosphate pathway

... the non-oxidative synthesis of 5 carbon sugars. The pathway is one of the three main ways the body creates reducing molecules to prevent oxidative stress , accounting for approximately 10% of NADPH production in humans. Contents showTocToggle("show","hide") 1 Oxidative phase 2 ...

Phage

... the host cell. They do not kill the cell, but monitor ( via some proteins they code for) the status of their host. When the host cell shows signs of stress (meaning it might be about to die soon), the endogenous phages become active again and start their reproductive cycle, resulting in the lysis of the ...

Prophage

... phage in its integrated status. Its genome can be integrated into the bacterial host chromosome or exists as an extrachromosomal plasmid . When stress in the host is detected, the phage enters its reproductive cycle. ...

Selective serotonin reuptake inhibitor

... a precedent for the pursuit of "normal" mental or emotional functioning by chemical means versus a more holistic approach (diet, exercise, sleep, stress reduction, etc). Furthermore, in late 2004 was much media attention given to a proposed link between SSRI use and juvenile suicide. For this ...
