Chapter 2 In solution, py(mi)ridinols 1.33, 1.34 and 1.35 are 2-, 5- and 28-fold more reactive antioxidants, respectively, than α-TOH (the most potent lipid-soluble antioxidant in nature). In order to develop a highly-reactive fluorescent indicator of lipid peroxidation in cells, we sought to couple these antioxidants with boron-dipyrro- methene (BODIPY) dyes, such that the resulting conjugates will display a significant fluorecence enhancement upon oxidation. This chapter details efforts towards the synthesis of these compounds. Chapter 3 Lipoxygenases are a family of important enzymes that catalyze the dioxygenation of arachidonic acid to yield a variety of potent lipid mediators that have been implicated in the pathogenesis of numerous degenerative conditions. We have undertaken a preliminary study of the effect of replacing the unsaturation in the related polyunsaturated lipid linoleic acid with cyclopropane rings on both the oxidizability of the lipid, as well as lipoxygenases ability to ...

Of all diuretic drugs, the mercurial diuretics have the established advantage of combining effectiveness and safety when administered intramuscularly.1 They may on occasion cause local or generalized reactions of varying degree. Chemical modifications of these organic mercurial compounds have been employed in an effort to minimize such toxic effects.2, 3 Another mercurial compound, mercaptomerin sodium (Thiomerin) has recently been introduced. This preparation is an organic mercurial combined with a mercaptan (disodium salt of N-(gamma-carboxy-methyl-mercaptomercuri-beta-methoxy) propyl camphoramic acid). Formula: C(CH3), C(COONa) (CH3), CH2, CH2, CH(ONH CH2) CH (OCH2) CH2HgSCH2.. The stated clinical characteristics of mercaptomerin are:. 1. It is an effective ...

Previous work has demonstrated that loss of crucial components of the zebrafish MTJ, either intracellularly (dystrophin, integrin-linked kinase) or extracellularly (Lama2), results in an embryonic myofibre detachment phenotype (Bassett et al., 2003; Hall et al., 2007; Postel et al., 2008). In this study we extend our knowledge of the role of another extracellular component, Lamb2, by showing that a disorganised MTJ, detachment of muscle fibres and sarcolemmal damage all result from a missense mutation in the zebrafish lamb2 gene in the softm272a mutant. Whereas secondary changes in levels of LAMB2 immunoreactivity have been seen in congenital muscular dystrophy, this laminin chain has not been implicated as a direct cause of inherited muscle disease (Cohn et al., 1997). Rather, mutations in LAMB2 cause Pierson syndrome, an autosomal recessive, oculorenal disease with neurological involvement (Zenker et al., 2004). No dystrophy has been reported in Pierson syndrome; however, deletion of Lamb2 in ...

1. The ability of phlorrhizin to inhibit the galactosylation of glucose was re-examined with Golgi membrane vesicles purified from rat mammary gland, and extended to the galactosylation of several glucose analogues and N-acylglucosamines. 2. The inhibition is ascribed, contrary to previous conclusions, to a general annealing of leaky membranes comprising a minority of the vesicles. 3. Three thiol reagents were able to inhibit the galactosylation of N-acylglucosamines with less, or no, inhibition of galactosylation of glucose. This demonstrates the existence of a Golgi membrane carrier that distinguishes between glucose and N-acylglucosamines. ...

Previous findings support the idea that one function of the DGC is to provide mechanical reinforcement of the sarcolemma and to maintain membrane integrity during cycles of contraction and relaxation (Weller et al., 1990; Clarke et al., 1995; Petrof et al., 1993). To test the involvement of sarcolemmal damage in the pathogenesis of muscle fiber degeneration and necrosis, we injected animal models for muscular dystrophy with EBD. Intracellular accumulation of the dye in skeletal muscle fibers indicated loss of sarcolemmal integrity due to plasma membrane disruptions. As a further test of altered membrane permeability, we examined the intracellular deposition of serum proteins in skeletal muscle fibers in the murine models and in patients with DMD and CMD.. Our results demonstrated that focal plasma membrane defects have actually occurred in vivo and not, as argued, during biopsy (Bradley and Fulthorpe, 1978). The diffuse intracellular distribution of the tracer implied a break in the structural ...

In response to lowered blood pressure, the renin enzyme cleaves angiotensin-1 from angiotensin. Angiotensin-converting enzyme (ACE) then removes a dipeptide to yield the physiologically active peptide angiotensin-2, the most potent pressor substance known, which helps regulate volume and mineral balance of body fluids. The Angiotensin 2 [3-8] Peptide binds specifically to a new angiotensin binding site distinct from angiotensin 2 receptors.. ...

Incubation of cultured bovine adrenal medullary cells with p-chloromercuribenzoate (50-500 microM), a sulfhydryl-reacting agent, caused an increase in the secretion of catecholamines, p-Chloromercuriphenyl sulfonate, a p-chloromercuribenzoate analogue that poorly penetrates the cell membrane, caused a similar increase in catecholamine secretion. In both cases, catecholamine secretion was dependent on extracellular Ca2+. Furthermore, p-chloromercuribenzoate caused both 45Ca2+ influx into the cells and an increase in the intracellular free Ca2+ concentration. The increases in catecholamine secretion and 45Ca2+ influx behaved similarly in relation to p-chloromercuribenzoate concentration. The time courses of the increased secretion, 45Ca2+ influx, and intracellular free Ca2+ concentration by p-chloromercuribenzoate were also quite similar. The stimulation of catecholamine secretion by p-chloromercuribenzoate was reversed by washing the cells with dithiothreitol-containing medium, but not by dithiothreitol

Substrate effects on the activation kinetics of Chinese hamster dihydrofolate reductase by p-chloromercuribenzoate (pCMB) have been studied. On the basis of the kinetic equation of substrate reaction in the presence of pCMB, all modification kinetic constants for the free enzyme and enzyme-substrate binary and ternary complexes have been determined. The results of the present study indicate that the modification of Chinese hamster dihydrofolate reductase by pCMB shows single-phase kinetics, and that changes in the enzyme activity and tertiary structure proceed simultaneously during the modification process. Both substrates, NADPH and 7,8-dihydrofolate, protect dihydrofolate reductase against modification by pCMB. In the presence of a saturating concentration of NADPH, the value of kcat for 7,8-dihydrofolate in the enzyme-catalysed reaction increased four-fold on modification of Cys-6, accompanied by a two-fold increase in Km for the modified enzyme. The utilization of the binding energy of a ...

wont cause problems.. Mercurial also differs significantly from Git in terms of how the hash is obtained. Gits hash is computed from raw content preceded by a header derived directly from the objects role and size. (Takeaway: the header is static and can be derived trivially.) Mercurials hash is computed from raw content preceded by a header. But that header consists of the 20 byte SHA-1 hash(es) of the parent revisions in the revlog to which the content is being added. This chaining of hashes means that the header is not always static nor always trivially derived. This means that the same content can be stored in the revlog under multiple hashes. It also means that it is possible to store differing content having a hash collision within the same revlog! But only under some conditions - Mercurial will still barf in some scenarios if there is a hash collision within content tracked by the revlog. This is different from Gits behavior, where the same content always results in the same Git ...

While testing, the urine sample reacts with anti-LH antibody, conjugated to the colored particles and pre-coated on the sample pad. The reacted mixture migrates via the membrane, and interacts with reagents on membrane. If the sample has sufficient amount of LH, a colored band forms in the test region. This colored band in membrane signifies a positive result. The display of a colored band in control region indicates a procedural control, which is a sign of addition of proper volume of specimen.. ...

Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, derived from natural fats and oils. They are colourless oily liquids or waxy solids (depending on the carbon numbers), although impure samples may appear yellow. More at Wikipedia https://en.wikipedia.org/wiki/Fatty_alcohol ...

Yves, You dont say whether or not you are briefly fixing the sections. The binding of the b-galactosidase to lysosomes is relatively loose, and that may contribute to what you are seeing. Brief fixation in paraformaldehyde vapor may suffice. Also, something worth considering, have you tried inhibiting the enzyme with e.g. D-galactonolactone, lactose and/or p-chloromercuribenzoate? This is only speculation as I have never come across this phenomenon personally, but, as with Ray, have never performed the technique on pancreas.=0D One way to get by the problem of diffusion artefact, if that is what this is, would be to employ a semi-permeable membrane enzyme =0Ahistochemical technique.
