Degradation increased risk

Several dosage forms carry an increased risk of degradation or adjunct formation. Products such as injections and aerosols are more likely to interact with volatiles or extractables from packaging and closure systems. Tablets have the potential to form adjuncts with excipients (specifically, lactose has been shown to form adjuncts in tablets). Non-CFC propellants in aerosols have a large number of impurities that typically do not interact with drug substances, but the potential for these interactions does still exist. Creams, ointments, lotions, and other such products will each have specific interactions that should be considered while evaluating the impurity profile of a drug product. [Pg.376]

A variety of known sleep disorders have been documented to affect waking function. Sleep apnea is one example that can degrade waking alertness and performance and has been shown to increase risk for car accidents (64,65). Healthy sleep activities could range from informational materials to actual diagnostic screening of individuals in safety-sensitive positions. [Pg.244]

By the year 2050, the number of people on Earth is expected to increase to 9.2 billion from the current 6.7 billion (Population Division, 2007). What is the best way to produce enough food to feed all these people If we continue with current farming practices, vast amounts of wilderness will be lost, millions of birds and billions of insects will die, farm workers will be at increased risk for disease, and the public will lose billions of dollars as a consequence of environmental degradation. Clearly, there must be a better way to resolve the need for increased food production with the desire to minimize its impact. [Pg.218]

Carboplatin Carboplatin is incompatible with aluminum and should not be mixed with 0.9% sodium chloride, since it degrades to cisplatin, thereby increasing risk of associated toxicity.207... [Pg.360]

Toxicity can result from shRNA expression in non-target tissue and accumulation of shRNA in the delivery vehicle in the liver or the kidneys. Transfection into non-cancerous cells can be especially deleterious in shRNA therapeutics because the RNAi target may be an essential transcript. Delivery vehicles that are resistant to degradation increase the serum half-life of the therapeutic and may increase its penetration in poorly perfused areas of tumor tissue. On the other hand, this also increases the risk of toxicity due to accumulation. Rapid polyplex degradation might be more likely to have a better safety profile but... [Pg.24]

Insulin and tri-iodothyronine (T3) increase the binding of LDLs to liver cells, whereas glucocorticoids (e.g. dexamethasone) have the opposite effect. The precise mechanism for these effects is unclear, but it may be mediated through the regulation of apo-B degradation. The effects of insulin and T3 on hepatic LDL binding may explain the hypercholesterolaemia and increased risk of atherosclerosis that have been shown to be associated with uncontrolled diabetes and hypothyroidism. [Pg.100]

It is necessary to Alter the fryer oil at some regular frequency. This is done to remove the particulate matter that accumulates in the oil, which makes the oil become dark. The product begins to exhibit a burnt odor or flavor if these particles are left in the oil. The accumulated particles can also act as catalysts for oil degradation, increasing the risk of Are hazards at the restaurants. [Pg.2246]

Understanding the results of risk assessment also means knowing the significant contributors to risk, i.e., knowing how improved performance can reduce risk and how degraded performance could increase risk. With this knowledge ... [Pg.62]

Because of their extreme stability against all kinds of aggressive chemical agent, for example radicals, perfluorocarbons and halofluorocarbons are not degraded in the lower layers of the atmosphere as are other pollutants. After several years, or even decades, they finally reach the stratosphere at altitudes of 20 to 40 km [26, 27]. In this layer, under the influence of short-wave UV irradiation, ozone is formed continuously (Scheme 1.2). This stratospheric ozone plays an essential role in preserving life on earth by absorbing the short-wavelength UV which would otherwise lead to an increase of photochemically induced mutations in most life-forms. For humans, over-exposure to short-wave UV irradiation results in a dramatically increased risk of skin cancer. Many crops and other plants also react rather sensitively towards an increase of UV exposure. [Pg.17]

The techniques become increasingly less effective the longer they are delayed. Performance degradation and risk assessment need to be considered when exceeding 6 hours. See FM 3 4, BDO risk assessment. Vehicle washdown is most effective if started within 1 hour, but will often have to be delayed for logistical reasons. ... [Pg.56]

Lipoprotein(a) is essentially an LDL particle that is covalently bound to apoprotein) a). It is called lipoprotein little a to avoid confusion with the apoprotein A found in HDL. The structure of apoprotein(a) is very similar to that of plasminogen, a precursor of the protease plasmin that degrades fibrin, a major component of blood clots. Lipoprotein(a), however, cannot be converted to active plasmin. There are reports that high concentrations of lipoprotein(a) correlate with an increased risk of coronary artery disease, even in patients in whom the lipid profile is otherwise normal. [Pg.642]
