Resilience, Risk and Protective Factors for British-Indian Children of Divorce

This paper considers resilience as a dynamic concept by looking at risk and protective factors for children of divorce in British-Indian Hindu and Sikh families using Bronfenbrenner’s ecological model for human development. The paper draws from a qualitative study which is based on data collected on experiences of twentyone British-Indian Adult Children of Divorce to illustrate risk and protective factors within cultural ideology, community and macro contexts. The paper concludes that resilience in individuals and communities needs to be considered as a process that is influenced by the interaction of the ecological systems. Risk and protective factors cannot be categorically identified and dynamic processes need to be acknowledged within particular contexts. This is particularly important for practitioners working with minority ethnic children and families towards understanding diversity of experiences and perspectives within minority cultures.

A rare haplotype of the vitamin D receptor gene is protective against diabetic nephropathy

Background. Vitamin D and its analogues are reported to have renoprotective effects in chronic kidney disease including diabetic nephropathy (DN). Vitamin D3 is converted to 1,25(OH) D3 by CYP2R1 and CYP27B1. The biological action of 1,25(OH) D3 is mediated via its receptor. VDR, CYP27B1 or CYP2R1 gene variants could modify the biological activity of vitamin D3. We have conducted the first case- control association study to determine the relationship between polymorphisms in VDR, CYP27B1 and CYP2R1 genes, and the risk of DN in individuals with type 1 diabetes.

Innate immunogenicity and in vitro protective potential of Schistosoma mansoni lung schistosomula excretory-secretory candidate vaccine antigens

Excretory secretory products (ESP) of Schistosoma mansoni developing larvae are ideal potential vaccines as such molecules may readily induce host primary immune responses, and local memory immune response effectors that would target, surround, and pursue the larvae while negotiating the lung blood capillaries. We herein characterized the cytokines response ESP, e.g., SG3PDH, 14-3-3-like protein, TPX, and calpain induce in the natural context of infection, and defined the global cytokine profile conducive to effective schistosome larvae killing. Accordingly, spleen cells (SC) taken from naive, and 7-, or 9-day S. mansoni-infected mice were stimulated in vitro with the selected ESP, in a recombinant or multiple antigen peptide (MAP) form, and examined for production of T helper type (Th) 1, Th2, and Th17 cytokines, and the ability to mediate in vitro attrition of lung-stage schistosomula. The study indicated that larval ESP principally elicit Th1 and Th17 type cytokines. Recombinant SG3PDH was the only test ESP to additionally activate SC from S. mansoni-infected BALB/c mice to release higher IL-4 levels than unstimulated SC and mediate significant (P

Synthesis of protective Mo-Si-B coatings in molten salts and their oxidation behavior in an air-water mixture

The formation of various phases during boronizing of silicided molybdenum substrates (MoSi2/Mo) was investigated. Boronizing treatments were conducted in molten salts under an inert gas atmosphere in the 700-1000 degrees C temperature range for 3-7 h. Depending on the process type (non-current or electrochemical) and molten salt temperature, the formation of different boride phases (MoB, Mo2B5, MoB2, MoB4) was observed. At the same time, substantial oxidation of the bulk molybdenum disilicide phase (MoSi2) to the Mo5Si3 phase was observed in non-current boronizing. The oxidation resistance of the coatings was investigated by the weight change in an air-water (2.3 vol.%) mixture at a temperature of 500 degrees C for a period up to 700 h. Results indicated that a two-phase microstructure consisting of the MoSi2, matrix phase with 12-15 wt.% of the MoB4 phase greatly improved the oxidation resistance of the molybdenum substrates. The weight gain rate observed was 6.5 center dot 10(-4) mg/cm(2) h. (c) 2006 Elsevier B.V. All rights reserved.

Protective qualities of surface treatments for concrete

Surface treatments are used as part of either a maintenance programme or repair work. In both cases, they provide additional protection to the concrete by either arresting or reducing the penetration of aggressive substances from the environment, Numerous materials are available for this purpose and their inherent generic properties differ considerably. Quite often this poses difficulties to practising engineers when selecting a surface treatment for a specific situation, In this review an attempt is made to explain the protective aspects of various surface treatments so that their selection can be made easier, The basic aspects of surface treatments are discussed: function, classification and performance requirements.

Immune responses and vaccine-induced immunity against Porcine circovirus type 2

Porcine circovirus type 2 (PCV2) is essential but not sufficient for postweaning multi-systemic wasting syndrome (PMWS) occurrence in pigs. The outcome of PCV2 infection depends on the specific immune responses that are developing during the infection. Diseased pigs are immunosupressed and unable to mount effective immune responses to clear the virus from circulation. In the final stage, PMWS-affected pigs suffer from extensive lymphoid lesions and altered cytokine expression patterns in peripheral blood mononuclear cells (PBMCs) and lymphoid organs. PCV2 infection can also be asymptomatic, demonstrating that not every infection will guarantee the occurrence of severe immunopathological disturbances. Asymptomatic animals have higher virus specific and neutralising antibody titres than PMWS-affected animals. Recent results have pointed out that the mechanisms by which PCV2 can affect the immune responses involve the induction of IL-10, virus accumulation into and modulation of plasmacytoid dendritic cells and the role of viral DNA in regulation of immune cell functions. Fourteen years after the first description of PMWS in Canada, efficient commercial vaccines against PCV2 are available. The vaccine success is based on activated humoral and cellular immune responses against PCV2. This review focuses on the recent research on immunological aspects during PCV2 infections and summarizes what is currently known about the vaccine-induced immunity. (C) 2010 Elsevier B.V.

Novel Protective Properties of IGFBP-3 Result in Enhanced Pericyte Ensheathment, Reduced Microglial Activation, Increased Microglial Apoptosis, and Neuronal Protection after Ischemic Retinal Injury

This study was conducted to determine the perivascular cell responses to increased endothelial cell expression of insulin-like growth factor binding protein-3 (IGFBP-3) in mouse retina. The contribution of bone marrow cells in the IGFBP-3-mediated response was examined using green fluorescent protein-positive (GFP(+)) adult chimeric mice subjected to laser-induced retinal vessel occlusion injury. Intravitreal injection of an endothelial-specific IGFBP-3-expressing plasmid resulted in increased differentiation of GF(P)+ hematopoietic stem cells (HSCs) into pericytes and astrocytes as determined by immunohistochemical analysis. Administration of IGFBP-3 plasmid to mouse pups that underwent the oxygen-induced retinopathy model resulted in increased pericyte ensheathment and reduced pericyte apoptosis in the developing retina. Increased IGFBP-3 expression reduced the number of activated microglial cells and decreased apoptosis of neuronal cells in the oxygen-induced retinopathy model. In summary, IGFBP-3 increased differentiation of GFP(+) HSCs into pericytes and astrocytes while increasing vascular ensheathment of pericytes and decreasing apoptosis of pericytes and retinal neurons. All of these cytoprotective effects exhibited by IGFBP-3 overexpression can result in a more stable retinal vascular bed. Thus, endothelial expression of IGFBP-3 may represent a physiologic response to injury and may represent a therapeutic strategy for the treatment of ischemic vascular eye diseases, such as diabetic retinopathy and retinopathy of prematurity.

An anthrax subunit vaccine candidate based on protective regions of Bacillus anthracis protective antigen and lethal factor

Studies have confirmed the key role of Bacillus anthracis protective antigen (PA) in the US and UK human anthrax vaccines. However, given the tripartite nature of the toxin, other components, including lethal factor (LF), are also likely to contribute to protection. We examined the antibody and T cell responses to PA and LF in human volunteers immunized with the UK anthrax vaccine (AVP). Individual LF domains were assessed for immunogenicity in mice when given alone or with PA. Based on the results obtained, a novel fusion protein comprising D1 of LF and the host cell-binding domain of PA (D4) was assessed for protective efficacy. Murine protection studies demonstrated that both full-length LF and D1 of LF conferred complete protection against a lethal intraperitoneal challenge with B. anthracis STI spores. Subsequent studies with the LFD1-PAD4 fusion protein showed a similar level of protection. LF is immunogenic in humans and is likely to contribute to the protection stimulated by AVP. A single vaccine comprising protective regions from LF and PA would simplify production and confer a broader spectrum of protection than that seen with PA alone.

Germany v Italy:The Triumph of Sovereign Immunity over Human Rights Law

This article analyses the doctrine of State immunity within the context of the recent judgment of the International Court of Justice (ICJ) concerning the Jurisdictional Immunities of the State (Germany v Italy: Greece intervening). The object of this article is to explore the implications of the State immunity from foreign judicial proceedings in cases of jus cogens crimes. Challenging the assumption that the law of immunity is merely procedural in nature, this article argues that there can be no immunity in cases of undisputed international crimes.

Assessment of cell-mediated immunity in a British population using multiple skin test antigens

An in vivo method of assessing the competence of the cell-mediated immune system (Multitest CMI) was used in 200 healthy volunteers (age range 17-88 years). The profile of reactivity to seven individual antigens was determined. A positive reaction was obtained in 96.5% of the subjects who reacted positively to at least one antigen with 78% reacting to two or more antigens. The number of positive responses and the degree of reactivity was significantly reduced in elderly subjects and in females aged 17-65 years. The Multitest CMI system provides a rapid and convenient method of assessing cell-mediated immunity (CMI) in vivo and could have a wide range of applications in the investigation of immunological, infective and neoplastic conditions.
