This final rule amends HUD's lead-based paint regulations to reduce blood lead levels in children under age six (6) who reside in federally-owned or -assisted pre-1978 housing, formally adopting a revised definition of "elevated blood lead level" (EBLL) in children under the age of six (6), in accordance with Centers for Disease Control and Prevention (CDC) guidance. It also establishes more comprehensive testing and evaluation procedures for the housing where such children reside. This final rule also addresses certain additional elements of the CDC guidance pertaining to assisted housing and makes technical corrections and clarifications...

Insulin like growth factor (IGF) signaling plays an important role in cell growth and proliferation and implicated in regulation of cancer, metabolism and aging. Here we report that IGF-1 level in blood and IGF-1 signaling demonstrates circadian rhythms. Circadian control occurs through Cryptochromes (CRYs), transcriptional repressors and components of the circadian clock. IGF-1 rhythms are disrupted in Cry deficient mice and IGF-1 level is reduced by 80% in these mice, which leads to reduced IGF signaling...

Background: Hypertension is an important risk factor for cardiovascular outcomes. Primary health care (PHC) physicians should be prepared to act appropriately in the prevention of cardiovascular risk factors. However, the rates of patients with control of blood pressure (BP) remain low. The impact of the reclassification of high BP by 24-hour ambulatory BP monitoring (ABPM) can lead to different medical decisions in PHC. Objective: To evaluate the agreement between the BP measured by a conventional method by PHC physicians and by 24-hour ABPM, considering different BP normal thresholds for the 24-hour ABPM according to the V Brazilian ABPM Guidelines and the European Society of Hypertension Guidelines...

PURPOSE: In patients with central visual field scotomata, a large part of visual cortex is not adequately stimulated. Patients often use a new eccentric fixation area on intact peripheral retina ("preferred retinal locus"-PRL) that functions as a pseudo-fovea. We used functional magnetic resonance imaging (fMRI) to examine whether stimulating this pseudo-fovea leads to increased activation or altered activation patterns in visual cortex in comparison to stimulating a comparable peripheral area in the opposite hemifield (OppPRL)...

BACKGROUND: Neonatal hyperbilirubinemia is influenced by a wide variety of factors, one of which is hemolysis. Serious hyperbilirubinemia may lead to a kernicterus with detrimental neurologic sequelae. Patients suffering from hemolytic disease have a higher risk of developing kernicterus. Carbon monoxide (CO), a byproduct of hemolysis or heme degradation, was described by Sjöstrand in the 1960s. It is transported as carboxyhemoglobin (COHb) and exhaled through the lungs. We were interested in a potential correlation between COHb and total serum bilirubin (TSB) and the time course of both parameters...

Alcohol exposure during pregnancy can cause adverse effects to the fetus, because it interferes with fetal development, leading to later physical and mental impairment. The most common clinical tool to determine fetal alcohol exposure is maternal self-reporting. However, a more objective and useful method is based on the use of biomarkers in biological specimens alone or in combination with maternal self-reporting. This review reports on clinically relevant biomarkers for detection of prenatal alcohol exposure (PAE)...

Tumor necrosis factor superfamily-15 (TNFSF15; VEGI; TL1A) is a negative modulator of angiogenesis for blood vessel homeostasis and is produced by endothelial cells in a mature vasculature. It is known to be downregulated by vascular endothelial growth factor (VEGF), a major regulator of neovascularization but the mechanism of this interaction is unclear. Here we report that VEGF is able to stimulate the production of two microRNAs, miR-20a and miR-31, which directly target the 3'-UTR of TNFSF15. Additionally, we show that two VEGF-stimulated cell growth signals, Erk and Akt, are responsible for promoting the expression of miR-20a and miR-31...

BACKGROUND Treg cells play a central role in the suppression of immune response, and their suppressive capacity can be modulated by toll-like receptor (TLR) ligands. However, the detailed pathway of TLR ligand modulation is still unknown. The present study aimed to evaluate the effect of the high mobility group box-1 protein 1 (HMGB1) and lipopolysaccharide (LPS) on Treg cells through TLR4 signaling. MATERIAL AND METHODS Treg cells were purified from healthy human peripheral blood mononuclear cells (PBMCs) by magnetic-bead activity cell sorting (MACS), blocked by anti-TLR4 monoclonal antibody, and then incubated with different concentration of LPS or HMGB1...

HTLV-1 is the causative agent of a severe form of adult T cell leukemia/Lymphoma (ATL), and of a chronic progressive neuromyelopathy designated HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). Two important HTLV-1-encoded proteins, Tax-1 and HBZ, play crucial roles in the generation and maintenance of the oncogenic process. Less information is instead available on the molecular and cellular mechanisms leading to HAM/TSP. More importantly, no single specific biomarker has been described that unambiguously define the status of HAM/TSP...

Multiple sclerosis (MS) is normally considered a chronic inflammatory disease of the central nervous system (CNS), where T-cells breaching the blood brain barrier react against proteins of the axonal myelin sheaths, leading to focal plaques and demyelination in the brain and spinal cord. Many current therapies are immunosuppressive in nature and are designed to target the immune system at an early stage of the disease. But there is no cure and MS may evolve into a neurodegenerative disease, where immunomodulatory treatments appear less effective...

BACKGROUND: Offspring of obese mothers have increased risk of developing obesity and related short and long-term disease. The cause is multifactorial and may partly be explained by the unfavorable intrauterine environment. Intervention during pregnancy leading to a healthier lifestyle among obese may alter this. OBJECTIVE: To assess the effect of lifestyle intervention on markers of maternal metabolism and inflammation in 'the TOP (Treatment of Obese Pregnant Women)-study', a randomized controlled trial...

INTRODUCTION AND HYPOTHESIS: Anticholinergic medication is the medical treatment for overactive bladder (OAB). These drugs can act on the central nervous system and can lead to cognitive decline, dementia, and potentially death. Patients taking drugs with anticholinergic effects increase their anticholinergic burden-defined as the cumulative effect of taking one or more drugs that can have adverse effects. When prescribing anticholinergic medication for the elderly, we must choose the right drug...

Pregnancy, particularly late gestation, has been associated with a relatively high prevalence of obstructive sleep apnea (OSA). Intermittent hypoxia (IH), a hallmark of OSA, could impose significant long-term effects on somatic growth, energy homeostasis, and metabolic function in offspring. We hypothesized that IH during late pregnancy (LG-IH) may increase the propensity for metabolic dysregulation and obesity in adult offspring via epigenetic modifications. Time-pregnant female C57BL/6 mice were exposed to LG-IH or room air (LG-RA) during days 13-18 of gestation...

OBJECTIVE: Hyperglycemia causes the breakdown of the blood-retinal barrier by impairing endothelial nitric oxide synthase (eNOS) function. Statins have many pleiotropic effects such as improving endothelial barrier permeability and increasing eNOS mRNA stability. The objective of this study was to determine effect of simvastatin on l-arginine transport and NO production under high-glucose conditions in conditionally immortalized rat retinal capillary endothelial cell line (TR-iBRB). METHODS: Changes in l-arginine transport uptake and, expression levels of cationic amino acid transporter 1 (CAT-1) and eNOS mRNA were investigated after pre-treatment with simvastatin and NOS inhibitors (l-NMMA and l-NAME) under high-glucose conditions using TR-iBRB, an in vitro model of iBRB...

Insulinoma is a tumor derived from pancreatic β-cells, and the resulting hyperinsulinemia leads to characteristic hypoglycemia. Recent studies have reported the frequent overexpression of glucagon-like peptide-1 receptor (GLP-1R) in human insulinomas, suggesting that the binding of a radiolabeled compound to GLP-1R is useful for the imaging of such tumors. Exendin(9-39), a fragment peptide of exendin-3 and -4, binds GLP-1R with high affinity and acts as an antagonist. Accordingly, radiolabeled exendin(9-39) derivatives have also been investigated as insulinoma imaging probes that might be less likely to induce hypoglycemia...

The article incorrectly stated: "Elevations of both fibroblast growth factor 23 (FGF23) and parathyroid hormone (PTH) lead to hyperphosphatemia and hypocalcemia because of decreased urinary excretion of phosphorus." In fact, FGF23 normally acts to lower blood phosphate levels. Furthermore, an elevated phosphorus level causes an increase in serum calcium levels and not hypocalcemia. This information has been corrected in the online version of the article.
