Skin morphology and its role in thermoregulation in mole-rats, Heterocephalus glaber and Cryptomys hottentotus. (1/2331)

The skin structure of 2 Bathyergid rodents, the naked mole-rat (Heterocephalus glaber) and the common mole-rat (Cryptomys hottentotus) is compared, to investigate whether thermoregulatory differences may be attributed to different skin features. Histological and ultrastructural studies of the dorsal skin of these closely related species show morphological and structural similarities but differences in the degree of skin folding, thickness of the integument and dermal infrastructure were evident. The skin of the common mole-rat conforms with expected morphological/histological arrangements that are commonly found in mammalian skin. Many features of the skin of the naked mole-rat, such as the lack of an insulating layer and the loosely folded morphological arrangement contribute to poikilothermic responses to changing temperatures of this mammal. Further evidence for poikilothermy in the naked mole-rat is indicated by the presence of pigment containing cells in the dermis, rather than the epidermis, as commonly occurs in homeotherms. Lack of fur is compensated by a thicker epidermal layer and a marked reduction in sweat glands. Differences in skin morphology thus contribute substantially to the different thermoregulatory abilities of the 2 Bathyergids. The skin morphology is related to the poor thermoinsulatory ability of the animals while simultaneously facilitating heat transfer from the environment to the animal by thigmothermy and/or other behavioural means.  (+info)

Temperature regulation and heat dissipation during flight in birds. (2/2331)

Core and skin temperature were measured by radiotelemetry in starlings (Sturnus vulgaris) during 30 min flights in a wind tunnel. Core temperature was independent of ambient temperature from 0 to 28 degrees C. The temporal mean of the monitored core temperature during flight was 42-7 degrees C in one bird and 44-0 degrees C in another. These temperatures are 2-4 degrees C higher than the resting temperature in starlings, and are among the highest steady-state temperatures observed in any animal. Skin temperature on the breast was within a few degrees of core temperature. In some locations skin temperature was higher at low ambient temperatures than at intermediate ambient temperatures. An analysis of the data shows that a high core temperature does not function as an aid to head dissipation. On the contrary, insulation is adjusted to maintain a high temperature, presumably because it is necessary for flight. The increase in skin temperature at low ambient temperatures is believed to be a result of a decrease in heat flow through the breast feathers brought about by feather adjustments, to compensate for an unavoidable increase in heat flow in unfeathered or poorly feathered parts of the body.  (+info)

Modulation of the thermoregulatory sweating response to mild hyperthermia during activation of the muscle metaboreflex in humans. (3/2331)

1. To investigate the effect of the muscle metaboreflex on the thermoregulatory sweating response in humans, eight healthy male subjects performed sustained isometric handgrip exercise in an environmental chamber (35 C and 50 % relative humidity) at 30 or 45 % maximal voluntary contraction (MVC), at the end of which the blood circulation to the forearm was occluded for 120 s. The environmental conditions were such as to produce sweating by increase in skin temperature without a marked change in oesophageal temperature. 2. During circulatory occlusion after handgrip exercise at 30 % MVC for 120 s or at 45 % MVC for 60 s, the sweating rate (SR) on the chest and forearm (hairy regions), and the mean arterial blood pressure were significantly above baseline values (P < 0.05). There were no changes from baseline values in the oesophageal temperature, mean skin temperature, or SR on the palm (hairless regions). 3. During the occlusion after handgrip exercise at 30 % MVC for 60 s and during the occlusion alone, none of the measured parameters differed from baseline values. 4. It is concluded that, under mildly hyperthermic conditions, the thermoregulatory sweating response on the hairy regions is modulated by afferent signals from muscle metaboreceptors.  (+info)

Reversing adipocyte differentiation: implications for treatment of obesity. (4/2331)

Conventional treatment of obesity reduces fat in mature adipocytes but leaves them with lipogenic enzymes capable of rapid resynthesis of fat, a likely factor in treatment failure. Adenovirus-induced hyperleptinemia in normal rats results in rapid nonketotic fat loss that persists after hyperleptinemia disappears, whereas pair-fed controls regain their weight in 2 weeks. We report here that the hyperleptinemia depletes adipocyte fat while profoundly down-regulating lipogenic enzymes and their transcription factor, peroxisome proliferator-activated receptor (PPAR)gamma in epididymal fat; enzymes of fatty acid oxidation and their transcription factor, PPARalpha, normally low in adipocytes, are up-regulated, as are uncoupling proteins 1 and 2. This transformation of adipocytes from cells that store triglycerides to fatty acid-oxidizing cells is accompanied by loss of the adipocyte markers, adipocyte fatty acid-binding protein 2, tumor necrosis factor alpha, and leptin, and by the appearance of the preadipocyte marker Pref-1. These findings suggest a strategy for the treatment of obesity by alteration of the adipocyte phenotype.  (+info)

Effects of different light intensities during the daytime on circadian rhythm of core temperature in humans. (5/2331)

The present study was to determine the effects of bright light exposure during the daytime on core temperature rhythm. Eight female students participated as subjects. They were exposed to bright light of 5000 lux or dim light of 200 lux for 13 hours (06:30-19:30) for two consecutive days. Except the sleep period (22:30-06:30) and during the bright light exposure, light intensity was controlled at 200 lux. Rectal temperature data were collected every 10 min throughout the whole experimental period. The mean level of rectal temperature was not significantly different between the bright and the dim light conditions. However, the evening fall and the morning rise of rectal temperature were significantly greater in the bright light conditions on Day 2 compared to the dim. Furthermore, cosinor analysis showed that the acrophase of rectal temperature rhythm was earlier on Day 2 in the bright light conditions than the dim, and was significantly delayed on Day 2 compared to Day 1 in the dim light conditions. These results suggest that low intensity during the daytime for two consecutive days may induce a phase delay of core temperature rhythm rather than the bright light exposure at least in normally entrained female subjects.  (+info)

The Parkes Lecture. Heat and the testis. (6/2331)

The evidence for the lower temperature of the testes of many mammals is summarized, and the reasons suggested for the descent of the testes into a scrotum are discussed. Descriptions are given of the various techniques used for studying the effects of heat on the testis, whole body heating, local heating of the testes (by inducing cryptorchidism, scrotal insulation or immersion of the scrotum in a water bath), and heating of tissue or cell preparations in vitro. The effects of heat are discussed, effects on the testis (weight, histology, physiology, biochemistry and endocrinology), on the numbers and motility of spermatozoa in rete testis fluid and semen, on fertilizing ability of spermatozoa and on the subsequent development of the embryos produced when spermatozoa from heated testes are used to fertilize normal ova. The possible mechanisms for the damaging effects of heat are discussed, as well as the importance of heat-induced abnormalities in male reproduction in domestic animals and humans.  (+info)

Cytokines as endogenous pyrogens. (8/2331)

Cytokines are pleiotropic molecules mediating several pathologic processes. Long before the discovery of cytokines as immune system growth factors or as bone marrow stimulants, investigators learned a great deal about cytokines when they studied them as the endogenous mediators of fever. The terms "granulocytic" or "endogenous pyrogen" were used to describe substances with the biologic property of fever induction. Today, we recognize that pyrogenicity is a fundamental biologic property of several cytokines and hence the clinically recognizeable property of fever links host perturbations during disease with fundamental perturbations in cell biology. In this review, the discoveries made on endogenous pyrogens are revisited, with insights into the importance of the earlier work to the present-day understanding of cytokines in health and in disease.  (+info)

Body temperature regulation, also known as thermoregulation, is the process by which the body maintains its core internal temperature within a narrow range, despite varying external temperatures. This is primarily controlled by the hypothalamus in the brain, which acts as a thermostat and receives input from temperature receptors throughout the body. When the body's temperature rises above or falls below the set point, the hypothalamus initiates responses to bring the temperature back into balance. These responses can include shivering to generate heat, sweating to cool down, vasodilation or vasoconstriction of blood vessels to regulate heat loss, and changes in metabolic rate. Effective body temperature regulation is crucial for maintaining optimal physiological function and overall health.

Body temperature is the measure of heat produced by the body. In humans, the normal body temperature range is typically between 97.8°F (36.5°C) and 99°F (37.2°C), with an average oral temperature of 98.6°F (37°C). Body temperature can be measured in various ways, including orally, rectally, axillary (under the arm), and temporally (on the forehead).

Maintaining a stable body temperature is crucial for proper bodily functions, as enzymes and other biological processes depend on specific temperature ranges. The hypothalamus region of the brain regulates body temperature through feedback mechanisms that involve shivering to produce heat and sweating to release heat. Fever is a common medical sign characterized by an elevated body temperature above the normal range, often as a response to infection or inflammation.

Temperature, in a medical context, is a measure of the degree of hotness or coldness of a body or environment. It is usually measured using a thermometer and reported in degrees Celsius (°C), degrees Fahrenheit (°F), or kelvin (K). In the human body, normal core temperature ranges from about 36.5-37.5°C (97.7-99.5°F) when measured rectally, and can vary slightly depending on factors such as time of day, physical activity, and menstrual cycle. Elevated body temperature is a common sign of infection or inflammation, while abnormally low body temperature can indicate hypothermia or other medical conditions.

Skin temperature is the measure of heat emitted by the skin, which can be an indicator of the body's core temperature. It is typically lower than the body's internal temperature and varies depending on factors such as environmental temperature, blood flow, and physical activity. Skin temperature is often used as a vital sign in medical settings and can be measured using various methods, including thermal scanners, digital thermometers, or mercury thermometers. Changes in skin temperature may also be associated with certain medical conditions, such as inflammation, infection, or nerve damage.

Sweating, also known as perspiration, is the production of sweat by the sweat glands in the skin in response to heat, physical exertion, hormonal changes, or emotional stress. Sweat is a fluid composed mainly of water, with small amounts of sodium chloride, lactate, and urea. It helps regulate body temperature by releasing heat through evaporation on the surface of the skin. Excessive sweating, known as hyperhidrosis, can be a medical condition that may require treatment.

Hypothermia is a medically defined condition where the core body temperature drops below 35°C (95°F). It is often associated with exposure to cold environments, but can also occur in cases of severe illness, injury, or immersion in cold water. Symptoms may include shivering, confusion, slowed heart rate and breathing, and if not treated promptly, can lead to unconsciousness, cardiac arrest, and even death.

"Cold temperature" is a relative term and its definition can vary depending on the context. In general, it refers to temperatures that are lower than those normally experienced or preferred by humans and other warm-blooded animals. In a medical context, cold temperature is often defined as an environmental temperature that is below 16°C (60.8°F).

Exposure to cold temperatures can have various physiological effects on the human body, such as vasoconstriction of blood vessels near the skin surface, increased heart rate and metabolic rate, and shivering, which helps to generate heat and maintain body temperature. Prolonged exposure to extreme cold temperatures can lead to hypothermia, a potentially life-threatening condition characterized by a drop in core body temperature below 35°C (95°F).

It's worth noting that some people may have different sensitivities to cold temperatures due to factors such as age, health status, and certain medical conditions. For example, older adults, young children, and individuals with circulatory or neurological disorders may be more susceptible to the effects of cold temperatures.

Pyrogens are substances that can induce fever, or elevate body temperature above the normal range of 36-37°C (96.8-98.6°F). They can be either exogenous (coming from outside the body) or endogenous (produced within the body). Exogenous pyrogens include bacterial toxins, dead bacteria, and various chemicals. Endogenous pyrogens are substances produced by the immune system in response to an infection, such as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). These substances act on the hypothalamus, a part of the brain that regulates body temperature, to raise the set point for body temperature, leading to an increase in body temperature.

Fever, also known as pyrexia or febrile response, is a common medical sign characterized by an elevation in core body temperature above the normal range of 36.5-37.5°C (97.7-99.5°F) due to a dysregulation of the body's thermoregulatory system. It is often a response to an infection, inflammation, or other underlying medical conditions, and it serves as a part of the immune system's effort to combat the invading pathogens or to repair damaged tissues.

Fevers can be classified based on their magnitude:

* Low-grade fever: 37.5-38°C (99.5-100.4°F)
* Moderate fever: 38-39°C (100.4-102.2°F)
* High-grade or severe fever: above 39°C (102.2°F)

It is important to note that a single elevated temperature reading does not necessarily indicate the presence of a fever, as body temperature can fluctuate throughout the day and can be influenced by various factors such as physical activity, environmental conditions, and the menstrual cycle in females. The diagnosis of fever typically requires the confirmation of an elevated core body temperature on at least two occasions or a consistently high temperature over a period of time.

While fevers are generally considered beneficial in fighting off infections and promoting recovery, extremely high temperatures or prolonged febrile states may necessitate medical intervention to prevent potential complications such as dehydration, seizures, or damage to vital organs.

The hypothalamus is a small, vital region of the brain that lies just below the thalamus and forms part of the limbic system. It plays a crucial role in many important functions including:

1. Regulation of body temperature, hunger, thirst, fatigue, sleep, and circadian rhythms.
2. Production and regulation of hormones through its connection with the pituitary gland (the hypophysis). It controls the release of various hormones by producing releasing and inhibiting factors that regulate the anterior pituitary's function.
3. Emotional responses, behavior, and memory formation through its connections with the limbic system structures like the amygdala and hippocampus.
4. Autonomic nervous system regulation, which controls involuntary physiological functions such as heart rate, blood pressure, and digestion.
5. Regulation of the immune system by interacting with the autonomic nervous system.

Damage to the hypothalamus can lead to various disorders like diabetes insipidus, growth hormone deficiency, altered temperature regulation, sleep disturbances, and emotional or behavioral changes.

In a medical context, "hot temperature" is not a standard medical term with a specific definition. However, it is often used in relation to fever, which is a common symptom of illness. A fever is typically defined as a body temperature that is higher than normal, usually above 38°C (100.4°F) for adults and above 37.5-38°C (99.5-101.3°F) for children, depending on the source.

Therefore, when a medical professional talks about "hot temperature," they may be referring to a body temperature that is higher than normal due to fever or other causes. It's important to note that a high environmental temperature can also contribute to an elevated body temperature, so it's essential to consider both the body temperature and the environmental temperature when assessing a patient's condition.

The anterior hypothalamus is a region in the brain that has various functions related to endocrine regulation, autonomic function, and behavior. It contains several nuclei, including the paraventricular nucleus and the supraoptic nucleus, which are involved in the release of hormones from the pituitary gland. The anterior hypothalamus helps regulate body temperature, hunger, thirst, fatigue, and sleep-wake cycles. It also plays a role in processing emotions and stress responses. Damage to the anterior hypothampus can result in various endocrine and behavioral disorders.

A circadian rhythm is a roughly 24-hour biological cycle that regulates various physiological and behavioral processes in living organisms. It is driven by the body's internal clock, which is primarily located in the suprachiasmatic nucleus (SCN) of the hypothalamus in the brain.

The circadian rhythm controls many aspects of human physiology, including sleep-wake cycles, hormone secretion, body temperature, and metabolism. It helps to synchronize these processes with the external environment, particularly the day-night cycle caused by the rotation of the Earth.

Disruptions to the circadian rhythm can have negative effects on health, leading to conditions such as insomnia, sleep disorders, depression, bipolar disorder, and even increased risk of chronic diseases like cancer, diabetes, and cardiovascular disease. Factors that can disrupt the circadian rhythm include shift work, jet lag, irregular sleep schedules, and exposure to artificial light at night.
