Este artigo apresenta os resultados da determinação de 12 hidrocarbonetos policíclicos aromáticos (HPAs) em material particulado atmosférico (MPA) coletado na cidade de Niterói, RJ, Brasil. Amostras quinzenais de MPA foram coletadas durante 24 h, entre junho/2005 e maio/2006, no Campus da Universidade Federal Fluminense, localizado em uma área residencial e comercial no Centro de Niterói. Um am...

BACKGROUND Human platelet antigens (HPAs) are polymorphisms in platelet membrane glycoproteins (GPs) that can stimulate production of alloantibodies once exposed to foreign platelets (PLTs) with different HPAs. These antibodies can cause neonatal alloimmune thrombocytopenia, posttransfusion purpura, and PLT transfusion refractoriness. Most HPAs are localized on the main PLT receptors: 1) integr...

Mesoporous silica molecular sieves are a kind of unique catalyst support due to their large pore size and high surface area. Several methods have been developed to immobilize heteropolyacids (HPAs) inside the channels of these mesoporous silicas. The mesoporous silica-supported HPA materials have been widely used as recyclable catalysts in heterogeneous systems. They have shown high catalytic a...

The blood brain barrier (BBB) has evolved unique characteristics such as dense coverage of the endothelial cells by pericytes and interactions with astrocytes through perivascular endfeet. We study BBB formation in a 3-dimensional multicellular spheroid system of human primary brain endothelial cells (hpBECs), primary pericytes (hpPs) and primary astrocytes (hpAs). We show for the first time th...

BACKGROUND AND OBJECTIVE Hypothalamic-pituitary-adrenal axis suppression (HPAS) when treating children with corticosteroids is thought to be rare. Our objective was to determine the prevalence of and predictive factors for various degrees of HPAS. METHODS Clinical features of HPAS, doses, adherence, asthma score, and lung functions were recorded in 143 asthmatic children. The overnight metyra...

Aging coincides with a decline in lower limb muscle strength (LLMS). Preserving LLMS may be considered a very important determinant of functional independence in the elderly. To maintain LLMS the question arises whether habitual physical activitys (HPAs) can prevent a decline in LLMS. This review aims to determine the relationship between HPAs throughout life and LLMS above age 50. Using releva...

OBJECTIVES To determine the frequency of alloimmunization against human platelet antigens (HPAs) and human leucocyte antigen class 1 (HLA1) in multiparous women and multi-transfused patients.   METHODS This prospective study was conducted between January and August 2013, on 50 multiparous women with no history of previous blood transfusion recruited from the Obstetrics and Gynecology Clinic, ...

OF THE DISSERTATION Performance Analysis and Enhancement of OFDM-based WLAN Systems in the Presence of Nonlinear HPAs and Narrowband Interference for Single and Multiple Transmit Antennas by David Wei-Ting Chi Doctor of Philosophy in Electrical Engineering (Communication Theory and Systems) University of California San Diego, 2008 Professor Pankaj Das, Chair Professor Rene L. Cruz, Co-Chair Thi...

Hierarchical probabilistic automata (HPA) are probabilistic automata whose states are partitioned into levels such that for any state and input symbol, at most one transition with non-zero probability goes to a state at the same level, and all others go to states at a higher level. We present expressiveness and decidability results for 1-level HPAs that work on both finite and infinite length i...

Purpose: The Health Promoting Activities Scale (HPAS) is a short scale designed to question activities that may be beneficial for the mental and physical health of mother evaluate mothers in this sense. aim study was cross-culturally adapt Turkish version (HPAS-T) assess its reliability validity. 
 Methods: Eighty disabled children who received physiotherapy rehabilitation center were recr...
