Physiological state

Hyperbolic expansion The expansion of a fluid according to the law pV = Hypothalamus The temperature control center at the base of the brain, which regulates body temperature. Hypothermia The physiological state resulting when the deep core body temperature drops below 35 C. It results in vasoconstriction and shivering in an attempt to conserve body heat. 

However, there are disadvantages to using immobilised cells. The cell may contain numerous catalytically active enzymes, which may catalyse unwanted side reactions. Also, the cell membrane itself may serve as a diffusion barrier, and may reduce productivity. The matrix may sharply reduce productivity if the microorganism is sensitive to product inhibition. One of the disadvantages of immobilised cell reactors is that the physiological state of the microorganism cannot be controlled. 

The secretion of extracellular matrix proteins is also a function of smooth muscle cells but, since it occurs concurrently with other activities, it does not seem to constitute a physiological state. However, the fraction of the cellular resources which are devoted to it must be regulated these regulatory mechanisms are virtually unknown. In addition, it should be anticipated that autocrine activity occurs as well, involving peptides, prostaglandins, cytokines, and nitric oxide.

Human subjects degrade 1-2% of their body protein daily at rates that vary widely between proteins and with physiologic state. Key regulatory enzymes often have short half-lives. 

The role of CCR5 in the trafficking of leukocytes during CNS autoimmune diseases is poorly understood. Studies indicate that under noninflamed, physiologic states, few T cells enter the CNS and there is minimal CNS engraftment of blood-derived... 

Unlike chemicals, microorganisms are living materials, so growth conditions, the physiological state of the cells, and their metabolic activities will all influence the results of tests in which they may be used. 

Net chemical penetration of the skin is simply the sum of the accumulations by each of the mentioned routes and by other routes, for instance eccrine glands, where these contribute. The latter tiny glands are ubiquitously distributed over the body but are generally discounted in importance due to the limited fractional area they occupy and their unfavorable physiological states, either empty or profusely sweating.

There are various severity of illness scoring systems for sepsis and trauma (R11). Severity scoring can be used, in conjunction with other risk factors, to anticipate and evaluate outcomes, such as hospital mortality rate. The most widely used system is the Acute Physiology, Age, Chronic Health Evaluation II (APACHE II) classification system (K12). The APACHE III was developed to more accurately predict hospital mortality for critically ill hospitalized adults (K13). It provides objective probability estimates for critically ill hospitalized patients treated in intensive care units (ICUs). For critically ill posttrauma patients with sepsis or SIRS, another system for physiologic quantitative classification and severity stratification of the host defense response was described recently (R11). However, this Physiologic State Severity Classification (PSSC) has yet not been applied routinely in ICU setting. 

Thus recombinant enzyme constructs for use in activity assays should be designed to faithfully reflect the physiological state of the enzyme to the extent that is practical in vitro.

Host and parasite have coevolved over millions of years and exist in mutual tolerance, disease only being apparent when the balance is upset by the host being exposed to unusually high parasite burdens at times when immunocompetence is diminished by age, physiological state, disease or nutritional status. The host immune response is multifaceted and it is... 

At constant external input, RAnaiyte is a governed by the inputs (1 and 2) and outputs (3 and 4) within the system (i.e. the physiological state of the organism). Constant input means that the dietary supply does not change, while environmental factors that affect physiology may vary.
