Neighborhood-level Asian American Populations, Social Determinants of Health, and Health Outcomes in 500 US Cities.

Ethn Dis 2021 15;31(3):433-444. Epub 2021 Jul 15.

Department of Population Health, NYU Grossman School of Medicine, New York, NY.

Introduction: The US Asian American (AA) population is projected to double by 2050, reaching ~43 million, and currently resides primarily in urban areas. Despite this, the geographic distribution of AA subgroup populations in US cities is not well-characterized, and social determinants of health (SDH) and health measures in places with significant AA/AA subgroup populations have not been described. Our research aimed to: 1) map the geographic distribution of AAs and AA subgroups at the city- and neighborhood- (census tract) level in 500 large US cities (population ≥66,000); 2) characterize SDH and health outcomes in places with significant AA or AA subgroup populations; and 3) compare SDH and health outcomes in places with significant AA or AA subgroup populations to SDH and health outcomes in places with significant non-Hispanic White (NHW) populations.

Association of maternal angiotensin II type 1 and type 2 receptor combination genotypes with susceptibility to early-onset preeclampsia.

J Hum Hypertens 2021 Mar 23. Epub 2021 Mar 23.

Department of Embryology, Faculty of Medicine, University of Thessaly, Larissa, Greece.

Allelic variations affecting the activity of the maternal renin-angiotensin system may play a role in the development of hypertensive disorders of pregnancy like preeclampsia, its more severe early-onset form, and intrauterine growth restriction. We examined the association of common allelic variants of angiotensin II type 1 and type 2 receptor genes (AT1R and AT2R) sorted in five AT1R/AT2R receptor combination genotype groups with susceptibility to early-onset preeclampsia (EOP). The occurrence of AT1R (A1166C) and A2TR (C3123A) alleles in wild type (AA, CC), heterozygous (A/C, C/A), and homozygous (C/C, A/A) states was recorded in 84 women with a history of EOP and 84 age-matched controls sorted in five AT1R/AT2R receptor combination genotype (wild type: AA/CC, one mutant: AA/CA, AC/CC, two mutant: AC/CA, AA/AA, CC/CC, three mutants: AC/AA, CC/CA and four mutant: CC/AA) groups, by polymerase chain reaction-RFLP analysis.

Human brain blood flow and metabolism during isocapnic hyperoxia: the role of reactive oxygen species.

J Physiol 2019 02 26;597(3):741-755. Epub 2018 Dec 26.

Laboratory of Exercise Sciences, Fluminense Federal University, Niterói, Brazil.

Key Points: It is unknown whether excessive reactive oxygen species (ROS) production drives the isocapnic hyperoxia (IH)-induced decline in human cerebral blood flow (CBF) via reduced nitric oxide (NO) bioavailability and leads to disruption of the blood-brain barrier (BBB) or neural-parenchymal damage. Cerebral metabolic rate for oxygen (CMR ) and transcerebral exchanges of NO end-products, oxidants, antioxidants and neural-parenchymal damage markers were simultaneously quantified under IH with intravenous saline and ascorbic acid infusion. CBF and were reduced during IH, responses that were followed by increased oxidative stress and reduced NO bioavailability when saline was infused. Read More

IKKα controls ATG16L1 degradation to prevent ER stress during inflammation.

J Exp Med 2017 02 12;214(2):423-437. Epub 2017 Jan 12.

Institute for Tumor Biology and Experimental Therapy, Georg-Speyer-Haus, 60596 Frankfurt am Main, Germany

Inhibition of the IκB kinase complex (IKK) has been implicated in the therapy of several chronic inflammatory diseases including inflammatory bowel diseases. In this study, using mice with an inactivatable IKKα kinase (Ikkα), we show that loss of IKKα function markedly impairs epithelial regeneration in a model of acute colitis. Mechanistically, this is caused by compromised secretion of cytoprotective IL-18 from IKKα-mutant intestinal epithelial cells because of elevated caspase 12 activation during an enhanced unfolded protein response (UPR).

NFE2L2 Gene Variants and Arsenic Susceptibility: A Lymphoblastoid Model.

J Toxicol Environ Health A 2015 ;78(10):628-34

a Universidad Autónoma de la Ciudad de México, Posgrado en Ciencias Genómicas , Mexico City , Mexico.

Arsenic (As) exposure is a major risk for several types of cancer and metabolic diseases such as diabetes. The transcription factor nuclear factor erythroid 2-related factor (Nrf2) is a key mediator in the cellular defense against As-induced adverse effects. The -653G/A and -617C/A gene variants modulate expression levels of the Nrf2 coding gene (NFE2L2) and are postulated to be associated with several illnesses. Read More

Graded Otx2 activities demonstrate dose-sensitive eye and retina phenotypes.

Hum Mol Genet 2014 Apr 13;23(7):1742-53. Epub 2013 Nov 13.

Collège de France, Center for Interdisciplinary Research in Biology, UMR CNRS 7241/INSERM U1050, 11 place Marcelin Berthelot, Paris 75005, France.

In the human, mutations of OTX2 (Orthodenticle homeobox 2 transcription factor) translate into eye malformations of variable expressivity (even between the two eyes of the same individual) and incomplete penetrance, suggesting the existence of subtle thresholds in OTX2 activity. We have addressed this issue by analyzing retinal structure and function in six mutant mice with graded Otx2 activity: Otx2(+/+), Otx2(+/AA), Otx2(+/GFP), Otx2(AA/AA), Otx2(AA/GFP) and Otx2(GFP/GFP). Null mice (Otx2(GFP/GFP)) fail to develop the head and are embryonic lethal, and compound heterozygous Otx2(AA/GFP) mice show a truncated head and die at birth. Read More

Laboratory diagnosis of homozygous alpha thalassaemia.

West Afr J Med 2013 Apr-Jun;32(2):133-8

Medical Laboratory Sciences, School of Allied Health Sciences, College of Health Sciences, University of Ghana.

Background: Alpha-thalassaemia is one of the most prevalent haemoglobinopathies in the world. The molecular basis of the condition is mainly due to deletion of one or more alpha genes and occasional point mutations. The diagnosis and treatment of microcytic hypochromic anaemia is at times a problematic medical issue in Ghana due to co-existence of a-thalassaemia traits and iron deficiency anaemia (IDA) since there is no routine laboratory procedure for the diagnosis of the former.

Heart Rhythm 2013 Aug 22;10(8):1192-8. Epub 2013 Apr 22.

Department of Medical Physics, University of Wisconsin-Madison, Madison, Wisconsin 53705, USA.

Background: Blocked atrial bigeminy (BAB) and second-degree atrioventricular block with 2:1 conduction block (2:1 AVB) both present as ventricular bradycardia and can be difficult to distinguish by echocardiography.

Cannabinoid CB2 receptor gene (CNR2) polymorphism is associated with chronic childhood immune thrombocytopenia in Egypt.

Blood Coagul Fibrinolysis 2013 Apr;24(3):247-51

Clinical Pathology Department bPaediatrics Department, Faculty of Medicine, Cairo University, Cairo, Egypt.

Immune thrombocytopenia (ITP) is a heterogeneous autoimmune disorder characterized by thrombocytopenia with or without mucocutaneous bleeding manifestations. ITP patients have significant defects in immune self-tolerance: autoreactive T-lymphocyte clones are capable of directly damaging platelets and possibly megakaryocytes and are likely to proliferate under the influence of Th lymphocytes. The CB2 receptor is thought to be the principal cannabinoid receptor that mediates immune modulation by endocannabinoid. Read More

Polymorphisms in the IL-18 and IL-12B genes and their association with the clinical outcome in Croatian patients with Type 1 diabetes.

Gene 2013 Jan 6;512(2):477-81. Epub 2012 Nov 6.

Ruđer Bošković Institute, Division of Molecular Medicine, Zagreb, Croatia.

Genetic variants of IL-18 and IL-12B may be important in immunoregulatory abnormalities, observed in the patients with Type 1 diabetes mellitus (T1DM), that contribute to individual differences in response to a treatment. Therefore, we examined the significance of IL-18-137G/C, IL-18-607C/A, and IL-12B A/C polymorphisms in Croatians (187 patients, 236 controls), not only as factors that contribute to susceptibility to T1DM, but also as determinants of the clinical presentation of disease. The polymorphism screening has been performed using PCR sequence-specific primers (IL-18) or PCR-RFLP (IL-12B) approach. Read More
