Exception specifications

Exception handling is the process of responding to the occurrence, during computation, of exceptions – anomalous or exceptional events requiring special processing – often changing the normal flow of program execution. It is provided by specialized programming language constructs or computer hardware mechanisms.

Biotin protein ligase (BPL) catalyses the biotinylation of the biotin carboxyl carrier protein (BCCP) subunit of acetyl CoAcarboxylase and this post-translational modificationof a single lysine residue is exceptionally specific. The exact details of the protein–protein interactions involved are unclear as a BPL:BCCP complex has not yet been isolated. Moreover, detailed information is lacking on the composi-tion, biosynthesis and role of fatty acids in hyperthermo-philic organisms.

Aspartic proteinases of the A1 family are widely distributed among plant species and have been purified from a variety of tissues. They are most active at acidic pH, are specifically inhibited by pepstatin A and contain two aspartic residues indispensible for catalytic activity. The three-dimensional structure of two plant aspartic proteinases has been deter-mined, sharing significant structural similarity with other known structures of mammalian aspartic proteinases.

Enhancer of rudimentary (ER) is a small protein that has a unique amino acid sequence and structure. Its highly conserved gene has been found in all eukaryotic kingdoms with the exception of fungi. ER was proposed to be involved in the metabolism of pyrimidines and was reported to act as a transcriptional repressor in a cell type-specific manner.

COMPETITIVE SUPPLY CHAIN AND REVENUE MANAGEMENT: FOUR ESSAYS When the peer group measure is interacted with the choice index—in Column B, and again with additional controls in the remaining columns—the coefficient is indistinguishable from zero, with a negative point estimate in every specification. Panel B repeats this analysis, this time with the score earned by students when they were in the 12th grade.51 Again, estimates of the choice effect are imprecise but are—with one statistically insignificant exception—of the opposite sign from that predicted by the economic model....

Host Defense Mechanisms Preventing meningococcal growth in blood requires bactericidal and opsonic antibodies, complement, and phagocytes (Fig. 136-3). The major bactericidal antibodies are IgM and IgG, which (except for serogroup B) bind to the capsular polysaccharide. Immunity to meningococci is therefore serogroup specific. Antibodies to other surface (subcapsular) antigens may confer crossserogroup protection. PorA, PorB, Opc, and LOS appear to be major targets of cross-reactivity and of serogroup B bactericidal antibodies.

Anaplastic Large T/Null Cell Lymphoma: Treatment Treatment regimens appropriate for other aggressive lymphomas, such as diffuse large B cell lymphoma, should be utilized in patients with anaplastic large T/null cell lymphoma, with the exception that the B cell–specific antibody, rituximab, is omitted. Surprisingly, given the anaplastic appearance, this disorder has the best survival rate of any aggressive lymphoma. The 5-year survival is 75%.

Several general principles have arisen from these studies. Bevacizumab appears to potentiate the effects of many different types of active chemotherapeutic regimens used to treat a variety of different tumor types. No phase III trials have demonstrated single-agent activity for bevacizumab; colon and lung cancer trials have demonstrated a lack of activity when used alone. An exception may be renal cell cancer (RCC), a tumor that is specifically dependent upon VEGF as the result of deletion of the VHL tumor suppressor and activation of the HIF-1α transcription factor (see above).

Disease-Specific Nutritional Support SNS is basically a support therapy and is primary therapy only for the treatment or prevention of malnutrition. Certain conditions require modification of nutritional support because of organ or system impairment. For instance, in nitrogen accumulation disorders, protein intake may need to be reduced. However, in renal disease, except for brief periods of several days, protein intakes should approach requirement levels of at least 0.8 g/kg or higher up to 1.2 g/kg as long as the blood urea nitrogen does not exceed 100 mg/dL.

Catalytic oxidation of organic compounds is an extremely important field of chemistry, spanning the range from biological oxidations to large scale industrial production of commodity chemicals. However, many of these transformations can hardly be classified as organometallic reactions, since the catalysts (often simple metal salts) and the intermediates can be rather regarded as coordination complexes than organometallic compounds.
