In vitro method to assess the antimicrobial activity and potential efficacy of novel types of wound dressings. Thorn RM, Greenman J, Austin AJ. Centre for Research in Biomedicine, Faculty of Applied Sciences, Bristol, UK. AIMS: To develop a simple, reproducible in vitro static diffusion method using cellulose disks and defined species to test antimicrobial efficacy of wound dressings. METHODS AND RESULTS: Cellulose disks were inoculated by immersion in cell suspensions of target species Staphylococcus epidermidis, Candida albicans and Fusobacterium nucleatum. Test and control wound dressings were cut into equal sized squares 25 x 25 and applied to the surface of 10-mm thick tryptone yeast extract agar on test beds. Following a 2-h equilibration period, inoculated cellulose disks were inserted one per dressing ; at the interface between dressing and agar surface and a small weight applied over each square. At various sampling times, disks were removed and surviving cells enumerated by viable counts. Disk to disk variation for microbial loading was assessed using S. epidermidis for both initial n 16 ; and standard treatment n 16 ; conditions. The coefficient of variation was low 5% ; indicating good reproducibility for cell loading and treatment position on the test bed. Replicate assays n 6 ; using S. epidermidis and oxyzyme gels produced similar kill rates with low scatter R2 0.9 ; indicating good reproducibility between assays. Significant differences P 0.05 ; in kill rates were observed for different target species, types of dressing and test bed conditions + -blood and nutrients ; . CONCLUSIONS: The method is reproducible and useful in tracking the death kinetics of test species, enabling the comparison of different types of dressing. SIGNIFICANCE AND IMPACT OF THE STUDY: The reported method has significant advantages over established test procedures; it can be applied equally across a wide range of target species including anaerobes and yeasts ; , a wide range of conditions, and different types of surface dressings, including those relying upon oxygen diffusion.

Influence of Reinforcer Type on the Development and Maintenance of Gamma-Hydroxybutyrate Discrimination in Rats. Lisa E. Baker, Dori Pynnonen, and Alan D. Poling Western Michigan University, Kalamazoo, MI Recreational use of gamma-hydroxybutyrate GHB ; appears to be growing in popularity, which is cause for great concern given the recent rise in reported fatalities associated with its use. Unfortunately, relatively little is presently known regarding the neurobehavioral consequences of GHB use. Studies of drugs as discriminative stimuli have played an invaluable role in psychopharmacology. The few studies that have investigated the discriminative stimulus of GHB in nonhumans have reported inconsistent findings, which may be due to a number of important differences in research methodology. As part of an ongoing series of investigations on the discriminative stimulus effects of GHB, the present study investigated possible effects of the type of reinforcer on the development and maintenance of a GHB-vehicle discrimination in rats. Twelve male Sprague-Dawley rats, aged 50-60 days at the beginning of the study, were trained to discriminate GHB 200 mg kg, IP ; from vehicle in a two-choice drug discrimination operant procedure using an FR 20 schedule of food group 1, n 6 ; or water group 2, n 6 ; reinforcement. Stimulus generalization was assessed with GHB 50-400 mg kg, IP and IG ; , the GHB precursor gamma-butyrolactone GBL, 50-200 mg kg, IP ; and ethanol 1.0-4.0 g kg, IG ; . Responding maintained by food was significantly higher than responding maintained by water throughout the duration of the study. Although there was no significant difference between groups with respect to the number of training sessions required to meet the discrimination criterion, terminal accuracy of the discrimination was slightly greater in group 1 than in group 2. GHB produced dose-dependent increases in both groups with full generalization at the training dose following IP administration and at 400 mg kg when administered orally. GBL produced stimulus generalization in group 2, but only partial generalization in group 1, and substantially disrupted responding in both groups at the highest dose tested. Ethanol 1.0 4.0 g kg ; produced only partial generalization in both groups and appeared to disrupt responding to a greater degree in group 2. Results are discussed with respect to potential influences of reinforcer type on response rate and how this might affect GHB-maintained stimulus control.
I n previous studies in this laboratory, it was observed 1 ; that the laying hen cannot synthesize linoleic acid in toto from l-C14-acetate. The studies of Mead and his group 2 ; point clearly both to the mechanism of alternating dehydrogenation and addition of acetate to linoleic acid for the production of arachidonic, and to oleic acid for the production of eicosa-5, 8, ll-trienoic acids. The same laboratory has recently reported, however, that l-C14-octadeca-cis-12-enoic acid serves inefficiently, if at all, as a precursor of linoleic acid in the rat 3 ; . It thus evident that a double bond cannot be added to the 9 position of octadeca-cis-12enoic acid. However, it is possible that a much shorter acid with a double bond between the sixth and seventh carbons from the distal end can be extended into linoleic acid. The simplest acid possible with this potential is cis-2-octenoic acid. The present study demonstrates that this, in fact, takes place and ursodiol. Express antigen receptors, become responsive to antigenic stimulation, and develop into different functional classes Hale and Haynes, 1999 ; . Lymphocytes consist of distinct subsets that are quite different in respect of their functions and protein products, even though they all appear morphologically similar. In humans, B lymphocytes, are so called because in birds they were first shown to mature in the Bursa of Fabricius. In humans, B lymphocytes mature in the bone marrow, and are the only cells capable of producing antibodies. The antigen receptors of B-cells are membrane-bound forms of antibodies. Interaction of antigen with these membrane antibody molecules initiates the sequence of B-cell activation, which culminates in the development of effector cells that actively secrete antibody molecules. A second major class consists of T lymphocytes, whose precursors also arise in the bone marrow and then migrate to and mature in the thymus thymus-derived ; . T lymphocytes are further subdivided into functionally distinct populations, the helper inducer T-cells and the cytolytic suppressor T-cells. The principal functions of the T lymphocytes are to regulate all immune responses to protein antigens and to serve as effector cells for the elimination of intracellular microbes. T-cells do not produce antibodies, they have specificity for antigens; they recognize only peptide antigens attached to proteins that are encoded by genes in the major histocompatibility complex MHC ; and expressed on the surface of other cells, and as a result, they recognize and respond to cell surface-associated but not soluble antigens Katagiri et al., 2002 ; . Two major classes of T-cells are distinguished one from the other by the expression of surface markers CD4 and CD8. Helper cells are CD4 + T-cells; cytotoxic cells are CD8 + T-cells. CD4 and CD8 are surface glycoproteins, which function as adhesion molecules and T-cell "co-receptors" for antigen. In addition to T and B lymphocytes up to 10% of the circulating lymphocyte population is composed of large granular lymphocytes known as natural killer NK ; cells Hale and Haynes, 1999 ; . NK cells were named for their ability to kill tumours in a nonMHC-restricted fashion without the need for prior activation by tumour antigens. NK cells arise in the bone marrow and share a common precursor with T lymphocytes. Although NK cells can develop within and traffic through the thymus, they do not rearrange or productively express a T-cell receptor TCR ; , and they do not require the thymic microenvironment for maturation. 26.

The Travel Clinic Welcome to The Travel Clinic Website. This site is intended for anyone wishing to learn about the health risks that may be encountered when travelling, and to find out how to minimize or manage those risks. We tend to concern ourselves with what happens when "we go over there", but as the SARS outbreak has recently taught us, "things come here" as well. In addition to people being on the go, there is international trade in food and almost everything else. So there is the constant risk that almost any infectious organism or their vectors e.g. mosquitoes ; from one part of the world can show up on our dinner plate or in our back yard. The information contained in this site is not meant to "scare" the prospective traveller that's you! Rather, it is to inform you. I believe that the informed traveller will remain a healthier traveller, and will also be in a better position to make educated decisions when necessary. For when we fall ill abroad, we may be subject to poor though at times.excellent ; medical care in a language we do not understand. As well, you will be constantly bombarded with anecdotal medical opinions, especially about malaria. Some of what you hear will be incorrect, and at times dangerous! There are lots of excellent links throughout the site, so anything you need to know should literally be at your fingertips. As I tell the international volunteers to whom I give pre-departure medical briefings: there are lots of interesting diseases out there with a little bit of common sense, you probably won't get any of them you should probably know about them anyway, just in case in fact, you just might feel better while you are away.

According to World Health Organization 1996 ; "those benzodiazepines which are rapidly absorbed from the gastrointestinal tract have a prompt clinical action, whereas those which are slowly absorbed have a much slower onset of action. After oral administration, the absorption of diazepam, alprazolam, desmethyldiazepam e.g. formed from its precursor cloradiazepate ; , flurazepam leading to its aldehyde and hydroxyethyl metabolites ; midazolam and triazolam is very rapid. The peak plasma concentration occurs about one hour after ingestion.

Amprenavir is an inhibitor of HIV-1 protease. Amprenavir binds to the active site of HIV-1 protease and thereby prevents the processing of viral Gag and Gag-Pol polyprotein precursors, resulting in the formation of immature non-infectious viral particles. Antiviral Activity: Fosamprenavir has little or no antiviral activity in vitro. The in vitro antiviral activity of amprenavir was evaluated against HIV-1 IIIB in both acutely and chronically infected lymphoblastic cell lines MT-4, CEM-CCRF, H9 ; and in peripheral blood lymphocytes. The 50% effective concentration EC50 ; of amprenavir ranged from 0.012 to 0.08 M in acutely infected cells and was 0.41 M in chronically infected cells 1 M 0.50 mcg mL ; . The median EC50 value of amprenavir against HIV-1 isolates from clades A to G was 0.00095 M in peripheral blood mononuclear cells PBMCs ; . Similarly, the EC50 values for amprenavir against monocytes macrophage tropic HIV-1 isolates clade B ; ranged from 0.003 to 0.075 M in monocyte macrophage cultures. The EC50 values of amprenavir against HIV-2 isolates grown in PBMCs were higher than those for HIV-1 isolates, and ranged from 0.003 to 0.11 M. Amprenavir exhibited synergistic antiHIV-1 activity in combination with the nucleoside reverse transcriptase inhibitors NRTIs ; abacavir, didanosine, lamivudine, stavudine, tenofovir, and zidovudine; the non-nucleoside reverse transcriptase inhibitors NNRTIs ; delavirdine and efavirenz; and the protease inhibitors PIs ; atazanavir and saquinavir. Amprenavir exhibited additive antiHIV-1 activity in combination with the NNRTI nevirapine, the PIs indinavir, lopinavir, nelfinavir, and ritonavir; and the fusion inhibitor enfuvirtide. These drug combinations have not been adequately studied in humans. Resistance: HIV-1 isolates with decreased susceptibility to amprenavir have been selected in vitro and obtained from patients treated with fosamprenavir. Genotypic analysis of isolates from treatment-naive patients failing amprenavir-containing regimens showed mutations in the HIV-1 protease gene resulting in amino acid substitutions primarily at positions V32I, M46I L, I47V, I50V, I54L M, and I84V, as well as mutations in the p7 p1 and p1 p6 Gag and Gag-Pol polyprotein precursor cleavage sites. Some of these amprenavir resistance-associated mutations have also been detected in HIV-1 isolates from antiretroviral-naive patients treated with LEXIVA. Of the 488 antiretroviral-naive patients treated with LEXIVA or LEXIVA ritonavir in studies APV30001 and APV30002, respectively, 61 patients 29 receiving 32 and ativan.

These facts are sufficient to raise a fair and reasonable inference that mcdermott intended to personally use the precursors in the manufacturing process and danazol. David G. Howitt, PhD * , Department of Chemical Engineering and Materials, University of California, 1 Shields Avenue, Davis, CA 5616; and Simone Pugh, MEng, Forensic Science, University of California, 1 Shields Avenue, Davis, CA 95616 After attending this presentation, attendees will understand the significance of the extent of melting in arced wires This presentation will impact the forensic community and or humanity by assisting in fire cause and origin determinations. One of the consequences of a 110 or 220 volt electrical circuit being energized during a fire is that a local melting of the wires can occur. This can be produced either by a direct contact of wires between themselves or the grounded conduit, or, if the insulation that isolates the wires decomposes to enhance the electrical conductivity, the subsequent separation of the intermediary to produce a parting arc. The thermal decomposition of PVC insulation, for example, is well known to lead to the formation of distinctive regions of melting in what are otherwise relatively intact thermally annealed and oxidized copper wires. However, the general presence of this local melting cannot be broadly interpreted as a sign of electrical activity because the temperatures reached during structure fires are in some instances capable of melting copper directly. The determination of whether local melting should be interpreted as a sign of thermal or electrical activity in copper wires is typically based upon the subjective determination of the distinction of globules verses arc beads and the nature of the demarcation between the re-solidified regions NFPA 921 ; . The combination of the high melting point and thermal conductivity of copper means that a fairly extensive region of melting has to result from thermal damage from a fire because if only small regions are exposed to temperatures close to the melting point the substantial dissipation of heat through the wire will preclude any local melting. This is not the case for an electrical arc where the temperatures in an air gap that is created between the wires cannot be so effectively dissipated. Although the extent of melting due to the rapid increase in current in an arc between metal contacts should be fairly consistent, this may not extend to the case of arcing through char, where one might anticipate contributions from the precursory activity associated with lower excursions of current limited by the resistance of the connecting pathway. The extent of the melting and vaporizing of the wire that occurs in this case will be determined by the behavior of the resistance afforded by the residual insulation, so one might expect to see a variation in the degree of damage related to the rate at which the.

Some malignant tumours, such as breast, lung and prostate, have a predeliction to spread to bone and typically cause osteolytic breast and lung ; , osteoblastic prostate ; or mixed osteolytic and osteoblastic metastases Mundy & Martin 1993 ; . In addition to these solid tumors, myeloma typically causes extensive bone destruction and hypercalcemia Mundy 1995 ; . In all of these circum-stances, the bone is resorbed by osteoclasts stimulated by tumor cell products, rather than by the tumor cells Francini et al. 1993, Taube et al. 1994, Yoneda et al. 1994, Mundy & Yoneda 1995 ; . Malignant tumors can also cause humorally mediated hypercalcemia by releasing factors, such as parathyroid hormone-related hormone PTHrP ; , that act systemically to increase bone resorption and enhance renal tubular reabsorption of calcium. This subject has been reviewed elsewhere recently Guise & Mundy 1998 ; , and will not be covered here. Bone metastases can cause bone pain, pathologic fractures, nerve compression syndromes especially in myeloma ; and hypercalcemia mainly as a result of the effects of growth factors, cytokines and hormones released into the bone marrow around them Table 1 ; . These act in a number of ways to increase osteoclast numbers and activity. For example, interleukin IL ; -6, which is released by myeloma cells, promotes the prolif-eration of early osteoclast precursors. However, it does not enhance fusion of the precurors to form osteoclasts and has only weak stimulatory effects on osteoclasts. In contrast, IL-1, which is produced by some solid tumors Sato et al. 1988 ; , stimulates osteoclast formation and activity Uy et al. 1995 ; , in part by prolonging their life spans Jimi et al. 1998 ; through prevention of apoptosis Hughes et al. 1994 ; .

The recommendations in this report cover a broad spectrum of topics but still have one unifying theme they are all designed to help close ICT Skills Gaps in order to help the Egyptian ICT sector to be more successful. Success can be achieved in both the domestic and export markets, and indeed, success in one is closely intertwined with the other. These recommendations are also designed to help other industries improve their supply chain operations and overall productivity through increased use of ICT. There is a strong symbiotic relationship between general industrial growth and the health of the ICT sector. Unfortunately, due to the limited penetration of ICT inside Egyptian industry in general, see Industry Report from PfCE August 2003 ; , the benefits of operational improvement form using ICT and business process improvement has not yet impacted the economy. This may be one the best opportunities for improvement in multiple industry sectors and the ICT sector as a whole and desyrel.

Objective. To analyse the SLC22A12 URAT1 ; gene in primary gout patients, first-grade relatives and healthy controls and the possible association of them with demographic and clinical data. Subjects and Methods. We included 69 consecutive patients with diagnosis of primary gout, as well as 29 first-grade relatives and 120 healthy volunteers. Demographic and clinical data were obtained from the patients and relatives. DNA was purified from peripheral blood and all 10 exons of the SLC22A12 URAT1 ; gene were sequenced. Results. We found six different mutations in the SLC22A12 gene in 16 out of 69 23% ; patients with primary gout. Five mutations were in exon 5 and one in exon 4; five out of six mutations were heterozygous one compound heterozygous ; and one homozygous. The C850G mutation exon 5 ; was found in 11 gout patients, these patients have lower levels of triglycerides than the rest of the group: 160 56 vs 292 203 mg dl P 0.038 ; . In one family, we found SLC22A12 mutations in three relatives within exon 5. We did not find mutations in the other exons studied 13 and 610 ; , nor in any of the 10 exons of the 120 healthy volunteers. Conclusions. We found several mutations in SLC22A12 gene associated with primary gout, the definite role of these mutations in URAT1 activity needs to be further studied. The close interaction of cells with other cells and with extracellular matrix ECM ; components is a prerequisite in a number of biological activities. During development of the nervous system, axons often navigate a considerable distance depending on the type of molecular factors they encounter. Similarly, precursor and mature cells of haematopoietic origin home to specific locations during inflammation, wound healing, immune responses and thrombosis. Laminins LMs ; , major components of specialized ECMs known as basement membranes, are large heterotrimeric glycoproteins made of subunits. To date, 5, 3, and 3 chains have been identified, which by combination yield at least 15 different LM isoforms. These isoforms have a cell-and tissue-specific expression and are recognized by several integrins. The functional role of laminin isoforms has not been fully explored as the majority of early studies focused on LM-111 111, laminin-1 ; , the first laminin to be identified. The work presented in this thesis was therefore designed primarily to address synthesis, expression and, particularly, function of laminin isoforms in different cell types. First, we showed synthesis and expression of LM-211 211, laminin-2 ; and LM-411 411, laminin-8 ; by tooth pulp fibroblasts based on RT-PCR, FACS, immunoprecipitation and Western blot analysis. In functional studies, LM-411, unlike LM-211, was shown to strongly promote neurite outgrowth from sensory trigeminal ganglion TG ; neurons. This activity may be relevant to tooth innervation. In a following study, strong adhesion and migration promoting activities of 3-and 5-LMs, but not of 1-, 2- and 4-LMs, for human mast cells CBMCs and HMC.1 ; were demonstrated. Among the different laminin-binding integrins, 31 mediated the cell adhesion and migration. HMC-1 cells expressed transcripts for LM 5, 1 and 1 and, following stimulation, secreted the corresponding heterotrimer LM-511 511 ; . These findings demonstrated the pivotal role of 3- and 5-LMs and their 31 integrin receptor in mast cell adhesion and migration, and may explain the characteristic tissue localization of these immune cells in close apposition to epithelial, vascular and neural basement membranes. Synthesis of laminins by erythromegakaryocytic cell lines and their secretion by blood platelets were also investigated. Other than detecting transcripts for LM 3, 5, 1, and 1 in the cell lines, presence of fully heterotrimeric alpha-3 LM-311 and LM-321 ; and alpha-5 LM-511 and LM-521 ; laminins was demonstrated in these cells as well as in platelets. Both 3- and 5-LMs were secreted by the platelets following stimulation. Functional studies showed that LM-511 Lm-10 ; was the most platelet adhesive isoform followed by LM-411 LM-8 ; , LM-332 LM-5 ; and LM-111 LM-1 ; . This adhesion was largely mediated by 61 integrin. In spite of their adhesive properties, LM-332, LM-411 and LM-511 induced neither Pselectin expression nor cell aggregation, two signs of platelet activation. In addition, we reported expression of 3-LMs in blood vessels of skin, gingiva, lymph nodes and other tissues, mainly as LM-311 and or LM-321. Moreover, migration promoting and platelet-like particle forming activities of major vascular laminin isoforms LM-411 and LM-511 were demonstrated on in vitro differentiated CD41 + megakaryocytes, in comparison to other laminin isoforms. Thus, vascular laminins may contribute, when exposed to the circulation, to platelet adhesion but not activation and, in bone marrow, to megakaryocyte migration and platelet formation. Altogether, this thesis work illustrates the diverse functional role of laminin isoforms in different cell types. Key words: laminins, extracellular matrix, integrins, tooth pulp fibroblasts, mast cells, megakaryocytes, platelets, cell adhesion, cell migration, neurite outgrowth.

Diversity offer challenges when we're seeking trustworthy and specific information. Though information on the web expands daily, advances in searching software and literature databases have made the first challenge surmountable. As researchers in the early 21st century, most of us grow acquainted with a small handful of search engines and databases and use those consistently, gradually learning how they best work. Having said that, I commonly still find it agonizing to enter a Medline search on what I think is a specific topic only to discover 500 apparently relevant articles, or alternatively to shrewdly narrow down my search by combining terms and filters, resulting in a single review article addressing my topic precisely, but published in Swahili. The second challenge is that of reliability. Even when we do find a source of information sufficiently specific, how can we know it is reliable? Numerous studies of internet information have found that directions found on the web for treating common medical problems are as diverse as the number of pages offering them even professional-looking pages. There are subject-specific chat rooms and web-logs blogs ; in which anyone can publish personal opinions to the world, with alarming conviction but without accountability. In the medical field, however, when we seek cursory information, a Google search may suffice, but for direction in treatment decisions we most likely look to well-reputed texts, peer-reviewed journals, or association practice guidelines, all of which are conveniently published on the web. Unfortunately, even among these ostensibly reliable sources we find competing interests encouraging the publishing of incomplete results and unwarranted recommendations. Of course, this last problem is nothing new, and is not the web's fault. However, it does interact with this new technology: the overall value of the published word is diminished as the volume of information grows faster than anyone can read it, and the reliability of even "trustworthy" sources is questionable. The prevalence of conflicting study results confounds the outcomes of many systematic reviews. TABLE 1. Effect of antihistamines on altering the.

ISOLATION OF HUMAN PERIPHERAL BLOOD DENDRITIC CELLS FOR CLINICAL APPLICATION. Derek Hart, Maria Gilleece, David Munster, Slavica Vuckovic, Alejandro J Lpez. Mater Medical Research Institute Purpose of the Study Isolate blood dendritic cells DC ; for potential use in immunotherapy. Methods Current methods of expansion and enrichment of monocyte derived DC Mo-DC ; populations, require prolonged in vitro culture in the presence of exogenous growth factors. Furthermore the resulting Mo-DC have significant phenotypic and potentially functional ; differences to circulating DC. We have investigated the feasibility of purifying blood DC populations by a series of simple enrichment procedures, including positive selection with the monoclonal antibody CMRF-44, that do not require extensive culture in vitro. The resulting DC population relates closely to the physiological precursor population and may be functionally superior to Mo-DC. We undertook the isolation of these cells by sequential steps of enrichment from PBMC obtained from buffy coat or pheresis MNC preparations. Results After a short incubation, the cells were centrifuged over a Nycodenz gradient, a method previously used to enrich DC from the blood J. Immunol. Methods 184: 84. 1995 ; . The interface population was labeled with biotinylated CMFR-44 antibody Blood 89: 3708.1997 ; followed by streptavidin coated magnetic beads, and positive selection Miltenyii MACS ; . This procedure enriches CMRF44 + CD19-CD14- DC fifty fold to a purity 25%. Further enrichment to 80% purity was achieved by negative selection using CD14 plus CD19 specific antibodies prior to the positive selection step. Additionally to CMRF-44, other mAb identifying DC such as CMRF-56, have been produced and used in isolation protocols. Conclusions We describe the phenotypic and functional characteristics of these DC in comparison to conventional preparations. We propose further investigation of the potential of this routine blood DC purification platform as a basis for controlled trials of DC vaccination as therapy for cancer.

Follicular development through overriding the follicular selection process treatment during the midlate follicular phase ; . The FSH threshold. The FSH threshold concept advanced by Brown 1978 ; is crucial to successful COS. The concept states that all follicles potentially capable of undergoing preovulatory development have individual threshold requirements for stimulation by FSH Box 1 ; . Further healthy development of an individual follicle occurs only when its FSH threshold is exceeded. In a spontaneous cycle, the follicle with the lowest threshold requirement for FSH will become the first to synthesize oestrogen, and is thereby selected to ovulate. At the cellular level, the granulosa cells of this follicle are more sensitive to FSH, leading to earlier expression of high LH receptor-coupled aromatase activity see above ; . Hence, this follicle becomes uniquely equipped to undertake LH-responsive oestradiol production during the late follicular phase when plasma FSH concentrations decrease. Other follicles, with greater dependence on FSH and more limited responsiveness to LH, become nonovulatory and degenerate Zeleznik and Hillier, 1984 ; . All successful COS regimens have in common the aim to override the selection process by overcoming the FSH threshold requirements of multiple precursor follicles, and then to sustain their development to the point of oocyte retrieval. And DNA damage and greatly potentiated A toxicity as the result of reduced repair of A -induced oxidative modification of DNA bases. When maintained on a folic acid-deficient diet, amyloid precursor protein APP ; mutant transgenic mice, but not wild-type mice, exhibited increased cellular DNA damage and hippocampal neurodegeneration. Levels of A were unchanged in the brains of folate-deficient APP mutant mice. Our data suggest that folic acid deficiency and homocysteine impair DNA repair in neurons, which sensitizes them to oxidative damage induced by A . Key words: apoptosis; comet assay; glycosylase; oxidative stress; transgenic; uracil ton et al., 1997 ; or apoptosis triggered by DNA damage Kruman et al., 2000 ; . In AD the death of neurons in brain regions critical for learning and memory is believed to result from increased production and accumulation of insoluble forms of amyloid -peptide A ; , which may endanger and kill neurons by inducing oxidative stress and disrupting cellular ion homeostasis Yankner, 1996; Mattson, 1997 ; . Analyses of brain tissue from AD patients and of experimental cell culture and animal models of AD have provided evidence for the involvement of A and apoptotic biochemical cascades in the neurodegenerative process Mattson, 2000 ; . DNA damage, which is a potent trigger of neuronal apoptosis, has been documented in studies of AD patients and in cell culture and animal models of AD Mullaart et al., 1990; de la Monte et al., 1998; Torp et al., 1998; Adamec et al., 1999; Harada and Sugimoto, 1999; Love et al., 1999; Seidl et al., 1999 ; . In addition, non-neuronal cells from AD patients exhibit a defect in their ability to repair DNA damage Li and Kaminskas, 1985; Robison et al., 1987; Boerrigter et al., 1991 ; , suggesting a widespread abnormality in DNA repair mechanisms. Cells from Down's syndrome patients which have AD-like brain pathology ; exhibit hypersensitivity to ionizing radiation-induced DNA damage Otsuka et al., 1985 ; , and environmentally induced DNA damage may contribute to neurofibrillary degeneration in the ALSParkinsondementia complex of Guam Kisby et al., 1999 ; . In light of the data implicating increased DNA damage in neurons that degenerate in AD and the evidence that folic acid deficiency and homocysteine can impair DNA repair in non-neuronal cells, we used cell culture and mouse models of AD to test the hypothesis that folic acid deficiency and homocysteine sensitize neurons to A -induced death.

30, 199 ironically, gang land has learned, two hoods who took part in the plot including one who shot d'urso in the head and left him for dead have agreed to join d'urso as prosecution witnesses and testify that carmine pizza set the murder plot in motion. Blood monocytes contain laminin-8 THP-1, U-937, and Mono Mac 6 are monoblastic cell lines of malignant origin and represent monocyte precursors present in bone marrow 6, 27 ; . Monocytes are more differentiated cells and constitute 20 30% of blood mononuclear leukocytes 1, 2, 6, ; . As first approach to determine presence of laminin in monocytes, immunofluorescence flow cytometry of purified blood mononuclear cells was used Fig. 4 ; . Monocytes were gated by forward and side scatter and their identity confirmed by reactivity with mAb TUK4 to CD14, a monocyte marker. mAb LN-41 to 1, the most widely expressed laminin chain, bound minimally to intact monocyte cell surfaces, whereas practically all monocytes examined following permeabilization were consistently reactive. In two of seven experiments, cell surface expression of the laminin epitope was also observed data not shown ; . Myeloperoxidase, an intracellular marker of myelomonocytic cells, was detected only in permeabilized cells, as expected. To determine whether monocytes also contain laminin 1- and 4-chains to form laminin-8, the cell lysate of monocytes isolated by plastic adherence was immunopurified on the laminin 1 Ab column, and the isolated material was analyzed by Western blotting Fig. 5 ; . Similar to the observations with monoblastic cell lines, mAb DG10 to laminin 1-chain and mAb 22 to laminin 1-chain recognized polypeptides of 230 and 220 kDa, respectively, whereas rabbit Abs to 4 reacted with bands of 180 and 130 kDa, under reducing conditions!
