Tipping the balance:Haemoglobinopathies and the risk ofdiabetes

AIM: To establish a link between the risk of diabetes with haemoglobinopathies by examining available evidence of the effects of iron and blood glucose homeostasis from molecular to epidemiological ***: A systematic literature search was performed using electronic literature databases using various search terms. The International Diabetes Federation World Atlas was used to generate a list of populations with high rates of diabetes. Pub Med, Scopus and google Scholar were used to identify which of these populations also had a reported prevalence of haemoglobin ***: Abnormalities in iron homeostasis leads to increases in reactive oxygen species in the blood. This promotes oxidative stress which contributes to peripheral resistance to insulin in two ways:(1) reduced insulin/insulin receptor interaction; and(2) β-cell dysfunction. Hepcidin is crucial in terms of maintaining appropriate amounts of iron in the body and is in turn affected by haemoglobinopathies. Hepcidin also has other metabolic effects in places such as the liver but so far the extent of these is not well understood. It does however directly control the levels of serum ferritin. High serum ferritin is found in obese patients and those with diabetes and a meta-analysis of the various studies shows that high serum ferritin does indeed increase diabetes ***: From an epidemiological standpoint, it is plausible that the well-documented protective effects of haemoglobinopathies with regard to malaria may have also offered other evolutionary advantages. By contributing to peripheral insulin resistance, haemoglobinopathies may have helped to sculpt the so-called "thrifty genotype", which hypothetically is advantageous in times of famine. The prevalence data however is not extensive enough to provide concrete associations between diabetes and haemoglobinopathies- more precise studies are required.

Capacity of Old Trees to Respond to Environmental Change

引用

Journal of Integrative Plant Biology 2008年第11期50卷 1355-1364页

作者： Nathan g.phillips Thomas N.Buckley David T.Tissue Centre for Plant and Food Science University of Western Sydney Department of geography and Environment Boston University Department of Biology Sonoma State University School of Biological Earth and Environmental SciencesUniversity of New South Wales Bushfire Cooperative Research Centre

Atmospheric carbon dioxide [CO2] has increased dramatically within the current life spans of long-lived trees and old forests. Consider that a 500-year-old tree in the early twenty-first century has spent 70% of its life growing under preindustrial levels of [CO2], which were 30% lower than current levels. Here we address the question of whether old trees have already responded to the rapid rise in [CO2] occurring over the past 150 years. In spite of limited data, aging trees have been shown to possess a substantial capacity for increased net growth after a period of post-maturity growth decline. Observations of renewed growth and physiological function in old trees have, in some instances, coincided with Industrial Age increases in key environmental resources, including [CO2], suggesting the potential for continued growth in old trees as a function of continued global climate change.

A humanized mouse model to study human immune response in xenotransplantation

引用

Hepatobiliary & Pancreatic Diseases International 2012年第5期11卷 494-498页

作者： Peta phillips Center for Transplant and Renal Research Westmead Millennium InstituteWestmead HospitalWestmeadNSW Sydney 2145Australia

BACKgROUND: A major barrier to the clinical application of xenotransplantation as a treatment option for patients is T cell-mediated rejection. Studies based on experimental rodent models of xenograft tolerance or rejection in vivo have provided useful information about the role of T cell immune response in xenotransplantation. However not all observations seen in rodents faithfully recapitulate the human situation This study aimed to establish a humanized mouse model of xenotransplantation, which mimics xenograft rejection in the context of the human immune system. METHODS: NOD-SCID IL2rγ -/- mice were transplanted with neonatal porcine islet cell clusters (NICC) followed by reconstitution of human peripheral blood mononuclear cells (PBMC). Human leukocyte engraftment and islet xenograft rejection were confirmed by flow cytometric and histological analyses. RESULTS: In the absence of human PBMC, porcine NICC transplanted into NOD-SCID IL2rγ -/- mice revealed excellent graft integrity and endocrine function. Human PBMC demonstrated a high level of engraftment in NOD-SCID IL2rγ -/- mice. Reconstitution of NICC recipient NOD-SCID IL2rγ -/- mice with human PBMC led to the rapid destruction of NICC xenografts in a PBMC number-dependent manner. CONCLUSIONS: Human PBMC-reconstituted NOD-SCID IL2rγ -/- mice provide an ideal model to study human immune responses in xenotransplantation. Studies based on this humanized mouse model will provide insight for improving the outcomes of clinical xenotransplantation.

At a time of unprecedented need and despite significant advances in understanding brain function and related diseases,the drug pipeline for treatment of mental ill-health is failing[1,2].The reasons are many,including the unparalleled complexity of the central nervous system(CNS)itself,a lack of interdisciplinary research collaborations,increased drug development costs,and higher risk of clinical failure of CNS drugs compared with other areas of drug development[3–6].It is now widely recognized that individual dimensions of mental ill health arise from altered neural processes within specific brain circuits that may be shared across diagnostic categories[7,8].The inclusion of cognitive and social processes is particularly appropriate because cognitive dysfunction is of paramount importance to the understanding and treatment of many psychiatric disorders[9].This issue is further compounded by the lack of adequate medication to reverse cognitive and social *** respect to neurodevelopmental disorders that give rise to early onset of a spectrum of symptoms related to schizophrenia,attention deficit hyperactivity disorder,autism spectrum disorders(ASD)to name but a few,the need to discover effective treatment options is particularly urgent.

Experimental Phenomena of Improved Ohmic COnfinement Induced by Modulated Toroidal Current on the HT—7 Tokamak

引用

Chinese Physics Letters 2002年第10期19卷 1467-1469页

作者：毛剑珊 P.phillips 等 InstituteteofPlasmaPhysics ChineseAcademyofSciencesPOBOx1126Hefei230031 FusionResearchCenter C1510UniversityofTexasatAustinTx78712USA

The phenomena of improved ohmic confinement have been observed during the modulation of the toroidal current on the Hefei superconducting Tokamak-7 (HT-7). In the experiment, the programming ohmic heating field was modulated. A toroidal frequency-modulated current induced by modulated loop voltage was added on the plasma equilibrium current. The ratio of ac amplitude of the plasma current to the main plasma current is about 12-30%. These improved plasma confinement phenomena include the facts that the average electron density and the central electron temperature both increase, the Dα radiation from the edge is reduced, the magnetohydrodynamics is obviously suppressed by oscillating plasma current, and the global energy confinement time increases by 27-45%. It is found that the faster the modulation is, the more effective the improved ohmic confinement phase.
