Impact of climate and land use/land cover changes on malaria incidence in the Ecuadorian Amazon.

Malaria transmission is influenced by climate and land use/land cover change (LULC). This study examines the impact of climate and LULC on malaria risk in the Ecuadorian Amazon. Weekly malaria surveillance data between 2008 and 2019 from Ecuador's Ministry of Public Health were combined with hydrometeorological and LULC data.

Resolving trabecular metaphyseal bone profiles downstream of the growth plate adds value to bone histomorphometry in mouse models.

Introduction: Histomorphometry of rodent metaphyseal trabecular bone, by histology or microCT, is generally restricted to the mature secondary spongiosa, excluding the primary spongiosa nearest the growth plate by imposing an 'offset'. This analyses the bulk static properties of a defined segment of secondary spongiosa, usually regardless of proximity to the growth plate. Here we assess the value of trabecular morphometry that is spatially resolved according to the distance 'downstream' of-and thus time since formation at-the growth plate.

Association Between Clinical Pathways Leading to Medical Management and Prognosis in Patients With NSTEACS.

Introduction And Objectives: A large proportion of patients with non-ST-segment elevation acute coronary syndrome (NSTEACS) are initially selected for medical management (MM) and do not undergo coronary revascularization during or immediately after the index event. The aim of this study was to explore the clinical pathways leading to MM in NSTEACS patients and their influence on prognosis.

Methods: Patient characteristics, pathways leading to MM, and 2-year outcomes were recorded in a prospective cohort of 5591 NSTEACS patients enrolled in 555 hospitals in 20 countries across Europe and Latin America.

FDG-PET, 99mtc-HMPAO white blood cell SPET and bone scintigraphy in the evaluation of painful total knee arthroplasties.

Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET), technetium-99m hexamethylpropylene amine oxime (HMPAO)-labelled white blood cell (WBC) scintigraphy and bone scintigraphy were used in the evaluation of total knee arthroplasties (TKAs). We prospectively included 21 patients who had a three-phase bone scan for exclusion of infection of TKAs. Four hours after injection of 185 MBq 99mTc-HMPAO-labelled WBCs, planar and single-photon emission tomographic (SPET) imaging was performed.

Expression of mouse alpha-macroglobulins, lipoprotein receptor-related protein, LDL receptor, apolipoprotein E, and lipoprotein lipase in pregnancy.

The expression of the proteinase inhibitors of the alpha-macroglobulin family and of their clearance receptor was analyzed in the mouse during pregnancy, embryonal development, and adolescence. In total we studied seven partners of a complicated network of interactions in proteolysis and lipid metabolism:alpha-2-macroglobulin, murinoglobulin, the alpha-2-macroglobulin receptor/lipoprotein receptor related protein, the murine equivalent of the receptor associated protein or the 44 kDa heparin binding protein, the low density lipoprotein receptor, apolipoprotein E, and lipoprotein lipase. The data demonstrate that: i) the regulation of expression of mouse tetrameric alpha-2-macroglobulin results in very constant levels, similar to alpha-2-macroglobulin in humans; ii) single chain murinoglobulin, not alpha-2-macroglobulin, is subject to regulation of expression during pregnancy, around birth, and in adolescence; iii) an important role seems implicated for the alpha-2-macroglobulin receptor in placental lipid metabolism, probably making it the most important lipoprotein receptor to supply the fetus; iv) the massive increase in apolipoprotein E synthesis in uterus and placenta accentuate the changed lipid metabolism during pregnancy to an apolipoprotein E-based uptake by the alpha-2-macroglobulin receptor/lipoprotein receptor related protein; v) the increased expression of lipoprotein lipase underlines its role in the generation of free fatty acids in uterus and placenta as another mechanism of supply, next to receptor mediated endocytosis of lipoproteins.

Expression in mouse embryos and in adult mouse brain of three members of the amyloid precursor protein family, of the alpha-2-macroglobulin receptor/low density lipoprotein receptor-related protein and of its ligands apolipoprotein E, lipoprotein lipase, alpha-2-macroglobulin and the 40,000 molecular weight receptor-associated protein.

We have analysed by northern blotting and by in situ hybridization the expression patterns of eight different genes during the second half of mouse embryonic development and in adult mouse brain: we compared the messenger RNA levels of amyloid precursor protein and of the two amyloid precursor protein-like proteins 1 and 2 and we have analysed expression of apolipoprotein E and of its main receptor in brain, the alpha-2-macroglobulin/low density lipoprotein receptor-related protein and three other ligands: the proteinase inhibitor alpha-2-macroglobulin, the modifying enzyme lipoprotein lipase and the 44,000 molecular weight heparin binding protein, a ligand of unknown function. During embryogenesis the temporal expression pattern differs considerably for the three members of the amyloid precursor proteins. Total embryo messenger RNA levels of amyloid precursor protein and amyloid precursor protein-like protein 2 increased progressively, while amyloid precursor protein-like protein 1 messenger RNA showed a burst of synthesis between days 10 and 13 post-coitum.

Localization of the gene (RSN) coding for restin, a marker for Reed-Sternberg cells in Hodgkin's disease, to human chromosome band 12q24.3 and YAC cloning of the locus.

A novel 160-kDa intermediate filament associated protein, named restin (Reed-Sternberg intermediate filament associated protein), is specifically expressed in the malignant cells of Hodgkin's disease and anaplastic large cell lymphoma (Ki-1 lymphoma). The combination of chromosomal R-banding and fluorescence in situ hybridization (FISH) with the use of two fluorescent dyes, fluorescein isothiocyanate and propidium iodide, allowed simultaneous detection of the hybridized DNA sequence and chromosomal R-banding. By this technique, the gene coding for restin (RSN) was assigned to chromosome region 12q24.

Isolation, characterization and partial sequencing of Pregnancy Associated Mouse Protein PAMP1 identifies it as a novel female specific protein, unrelated to the alpha-2-macroglobulin family of proteinase inhibitors.

Pregnancy Associated Mouse Protein 1 (PAMP1) was isolated from plasma of female mice. An antiserum raised against the purified protein confirmed its immunochemical identity with the originally described PAMP1. Pregnant females were observed to have plasma levels of PAMP1 that are increased two-fold at day 10-13 of gestation relative to non-pregnant females, while male mouse plasma did not contain PAMP1.

Molecular cloning and sequencing of the murine alpha-2-macroglobulin receptor cDNA.

We have molecularly cloned and sequenced the mouse alpha-2-macroglobulin receptor cDNA. The cDNA contained 14849 bases with one large open reading frame of 4545 codons which is one more than in the corresponding human cDNA. Comparison of the predicted mouse and human receptor proteins revealed the very conserved nature of this receptor with an overall amino acid identity of more than 97%.

Mannose-specific lectins bind alpha-2-macroglobulin and an unknown protein from human plasma.

GNA, the mannose-specific lectin from Galanthus nivalis was confirmed to bind alpha-2-macroglobulin (A2M) but another protein was copurified with A2M from total human plasma. A total of 23 other lectins with diverse specificities were tested for reaction with human A2M and with three other members of the A2M family. NPA, a mannose-specific lectin isolated from Narcissus pseudonarcissus bulbs, and RSA, the Rhizoctonia solani agglutinin, were selected for further testing.

The relationship between blood pressure and environmental exposure to lead and cadmium in Belgium.

The question whether in the general population environmental exposure to lead and cadmium influences blood pressure after controlling for confounding factors remains debated. The environmental exposure of the Belgian population to both lead and cadmium is high as compared with other countries. The Cadmibel Cooperative Study was therefore designed to elucidate whether environmental exposure to lead and cadmium has any effect on blood pressure and renal function in the population at large.
