The Need for Near-Earth Multi-Spacecraft Heliospheric Measurements and an Explorer Mission to Investigate Interplanetary Structures and Transients in the Near-Earth Heliosphere.

Based on decades of single-spacecraft measurements near 1 au as well as data from heliospheric and planetary missions, multi-spacecraft simultaneous measurements in the inner heliosphere on separations of 0.05-0.2 au are required to close existing gaps in our knowledge of solar wind structures, transients, and energetic particles, especially coronal mass ejections (CMEs), stream interaction regions (SIRs), high speed solar wind streams (HSS), and energetic storm particle (ESP) events.

Comparison between two molar incisor hypomineralization detection criteria in epidemiological surveys.

Background: There is no consensus on which molar incisor hypomineralization (MIH) indices are more suitable for epidemiological surveys.

Aim: To compare the operational aspects and diagnostic ability of the MIH index (simplified/MIH_s and extended/MIH_e) with the MIH-Severity Scoring System (MIH-SSS) in classifying and diagnosing MIH.

Design: This cross-sectional study assessed the indices in a homogeneous group of 680 6- to 10-year-old schoolchildren in Bauru, Brazil, who had at least one first permanent molar, ensuring consistent conditions.

Sensitivity Treatments for Teeth with Molar Incisor Hypomineralization: Protocol for a Randomized Controlled Trial.

Background: The sensitivity of teeth with molar incisor hypomineralization (MIH) can affect children's quality of life and is a challenging problem for dentists. Remineralizing agents such as sodium fluoride varnish seem to reduce the sensitivity of teeth with MIH, but long-term clinical trials with large samples are still needed for more evidence about its effectiveness as a desensitizing agent before its clinical recommendation.

Objective: This randomized clinical trial aims to compare three treatment interventions for teeth with MIH and hypersensitivity.

Efficacy and safety of insulin in type 2 diabetes: meta-analysis of randomised controlled trials.

Background: It is essential to anticipate and limit the social, economic and sanitary cost of type 2 diabetes (T2D), which is in constant progression worldwide. When blood glucose targets are not achieved with diet and lifestyle intervention, insulin is recommended whether or not the patient is already taking hypoglycaemic drugs. However, the benefit/risk balance of insulin remains controversial.

Computer analysis of ocular results following selective blockade of growth-hormone in diabetic retinopathy. A collaborative study.

Computer storage and analysis of ocular data (visual acuity, fundus photographs and fluorescein angiographies) in diabetic retinopathy (DR) was used before and 1, 3 and 5 years after "Stereo-GIHF". This radiobiological procedure results in the selective inhibition of growth-hormone (GH) release. A series of 107 eyes were analyzed after division into 2 categories A and B (A: progressing background DR, n = 53, B: proliferative DR, n = 54).

Interaction of bovine epithelial lens (BEL) cells with extracellular matrix (ECM) and eye-derived growth factor (EDGF). II. Partial re-expression of the differentiated collagen distribution and phenotype.

The differentiated phenotype of bovine epithelial lens (BEL) cells consists primarily of type IV collagen production with homogeneous cellular form and monolayer organization. We have previously described how, after several subcultures, BEL cells lost this phenotype, which was replaced by a complex collagen mixture consisting predominantly of type I and type III collagens and a minor proportion of type IV collagen. The cells became irregular and formed multilayers.

In vitro study of gamma-glutamyl transpeptidase in rat lens.

gamma-Glutamyl transpeptidase catalyzes the initial step in the utilization of glutathione. In the lens, this enzyme is accessible to externally supplied substrates. An efflux of glutathione from the lens occurs when it was incubated in saline.

Evidence of leukotriene B4 biosynthesis in epithelial lens cells.

Metabolism of sodium (14C)-arachidonate by bovine epithelial lens cells was studied in culture. The cells converted arachidonic acid into a major product whose formation was not inhibited by aspirin, a cyclo-oxygenase inhibitor, but was suppressed by nordihydroguaiaretic acid, a lipoxygenase inhibitor and by dexamethasone. This metabolite co-migrated with leukotriene B4 in thin layer chromatography and high pressure liquid chromatography.

[Lymphangiomatous hyperplasia with eosinophilia; Kimura's disease (author's transl)].

Kimura's disease is a benign affection of young people in which there are non-specific subcutaneous nodules, mainly found in the region of the head. They can be identified by their particular histological appearance which includes vascular and inflammatory components, and by local and sometimes blood eosinophilia. The etiology is not known but could be allergic in nature.

The effect of high glucose concentration on the proliferation and the synthesis of lipids in endothelial cells in culture.

Influence of glucose concentration on growth and lipid synthesis was investigated in human endothelial cells in culture. The biosynthesis of lipids from acetate and glucose was present in endothelial cells, but a high glucose level in the culture medium failed to modify lipid synthesis. Neosynthesis in the lipidic fraction in the medium is higher when precursor is acetate compared to glucose.
