Shock minor

The rpoH gene is expressed from four different promoters. Under normal physiological conditions, the PI promoter is responsible for most of the rpoH transcription, while P2 and P4 promoters contribute varying minor amounts. The P3 promoter is under the control of the Eo holoenzyme (see below) and becomes induced at temperatures above 45 °C. The rpoH gene is expressed at all temperatures, and after a heat shock its transcription is increased by a factor of 1.5 only, but there is a large transient increase in intracellular levels. Two factors contribute significantly to this increase an enhanced rate of translation of the rpoH mRNA, and a transient stabilization in the half-life of... [Pg.14]

Type II NF is generally a monomicrobial infection caused by invasive GAS. Occasionally S. aureus is implicated. Type II often occurs after minor trauma, such as an insect bite or abrasion.3 It is more severe than type I because invasive strains of GAS produce toxins that induce erythema, systemic toxicity, multiorgan failure, and shock.22... [Pg.1080]

Extremely sensitive to shock, heat or minor friction, it has exploded very violently when touched with a glass rod or spatula. [Pg.507]

They conclude from estimated rates that reaction (8.63) is an insignificant contributor to prompt NO. However, they also point out that the reverse reaction (8.64) is very fast at room temperature and under shock tube conditions. Hence this step is a minor, but nonnegligible contributor to prompt NO and, because of the large endothermicity of reaction (8.64), its importance with respect to reaction (8.61) increases with increasing temperature. [Pg.429]

In other incidents, molten aluminum was accidentally spilled and contacted water or wet substrates. The reported damage varied from very minor to quite extensive. In all cases, the initial event was a sharp, local shock. The actual conditions (and quantities of metal and water involved) then seemed to dictate whether the overall incident was severe or mild. [Pg.171]

Since cmcible failures have occurred in numerous instances in the industry—with minor steam explosions, the violence of the event described above is believed to be due to the electrode falling into the water-metal mixture. Somehow, the steam-liquid water-molten titanium mixture changed character from a relatively slow increase in pressure to a sharp shock wave. [Pg.184]

Dosage adjustments Closely observe every patient exhibiting insulin resistance who requires concentrated insulin for diabetic control until appropriate dosing is established. Response will vary among patients. Most patients will show a tolerance to insulin, so that minor dosage variations will not cause untoward symptoms of insulin shock. Some may require only 1 dose daily others may require 2 or 3 injections per day. [Pg.303]

Hypoxic states Cardiovascular collapse (shock), acute CHF, acute Ml, and other conditions characterized by hypoxemia have been associated with lactic acidosis and may cause prerenal azotemia. If such events occur, discontinue metformin. Surgicai procedures Temporarily suspend metformin for surgical procedures (unless minor and not associated with restricted intake of food and fluids). Do not restart until the patient s oral intake has resumed and renal function is normal. [Pg.323]

Idiosyncratic dmg reactions (IDRs) are most commonly characterized by a reaction involving fever or rash, with or without internal organ involvement. The spectrum of responses ranges from a minor rash, to potentially fatal toxic epidermal necrosis and Stevens-Johnson syndrome. Immunoglobulin E (IgE)-mediated anaphylactic shock, occasional joint pain, hepatotoxicity or nephrotoxicity are also well documented [24]. The frequency of such reactions are unknown but estimated to be between 1 1000 and 1 10000 exposures and may be enhanced on re-challenging susceptible individuals with the same dmg. [Pg.150]

Naloxone is approved for use in neonates to reverse respiratory depression induced by maternal opioid use. In addition, naloxone has been used to improve circulation in patients in shock, an effect related to blockade of endogenous opioids. Other experimental and less well documented uses for naloxone include reversal of coma in alcohol overdose, appetite suppression, and alleviation of dementia from schizophrenia. Side effects of naloxone are minor. [Pg.327]

Sudden infant death syndrome. Water-soluble smoke extract, in cell culture supernatants of mouse fibroblasts (L-929 cell line), produced an increase in TNF-a from respiratory syncytial virus-infected cells. It decreased TNF-a from cells incubated with toxic shock syndrome toxin. Incubation with cigarette smoke extract decreased the NO production from respiratory syncytial virus-infected cells and increased the NO production from cells incubated with toxic shock syndrome toxin. Monocytes from a minority of individuals demonstrated extreme TNF-a responses and/or very high or very low NO. The proportion of samples in which extreme responses with a very high TNF-a and very low NO were detected was increased in the presence of the three agents to 20% compared with 0% observed with toxic shock syndrome toxin. One to 4% was observed with cigarette smoke extract or respiratory syncytial virus L Symphatomimetic activity. Water extract of the dried leaf, administered intravenously to cats at doses of 0.05 and 10-20 mg/kg. [Pg.333]

HMTeA, AN/TNT AN/Comp B) show that chge density, per se, has the strongest influence on critical pressure. Another important factor is reaction zone length. Chem differences betwn expls have a minor effect dynamites contg NG are a notable exception The problem of sensitivity testing is also examined because deton limit data show that the critical shock pressure decreases with increasing particle size. This seems to run counter to the results of minimum booster-type sensitivity tests. The discrepancy is resolved when shock wave initiation is viewed as a combination effect of both pressure duration... [Pg.424]

Chronic adrenocortical insufficiency is characterized by weakness, fatigue, weight loss, hypotension, hyperpigmentation, and inability to maintain the blood glucose level during fasting. In such individuals, minor noxious, traumatic, or infectious stimuli may produce acute adrenal insufficiency with circulatory shock and even death. [Pg.882]

The above conclusions were substantiated by the work of Bauer, Hou, and Resler.20 They shock-heated C2F4-02 mixtures diluted in 99% Ar to temperatures of 1200-2400°K in a single-pulse shock tube. The oxidation products were analyzed after each run and found to be principally CF20 and CO with slightly smaller amounts of CF4. The minor products included C2F6 and trace amounts of C3F6 and C02. At the lower temperatures CF20 was the most important product, but as the temperature was... [Pg.139]
