Monoglucoside versus Diglucoside Anthocyanin Evolution of Red Wine Produced Using a Fungus-Resistant Grape Cultivar (Downy Mildew and Powdery Mildew) under Oxidative Conditions.

The need to reduce the use of pesticides in viticulture is increasing the interest in wines produced using fungal-resistant grapevine varieties, which are characterized by relevant contents of both monoglucoside and diglucoside anthocyanins. Aging in wooden barrels induces oxygen permeation into wine, but little is known about diglucoside anthocyanin evolution. wine was subjected to addition of oxygen and oak chips, and the anthocyanin changes were followed for 1 month.

Maternal obesity damages the median eminence blood-brain barrier structure and function in the progeny: the beneficial impact of cross-fostering by lean mothers.

Maternal obesity is an important risk factor for obesity, cardiovascular, and metabolic diseases in the offspring. Studies have shown that it leads to hypothalamic inflammation in the progeny, affecting the function of neurons regulating food intake and energy expenditure. In adult mice fed a high-fat diet, one of the hypothalamic abnormalities that contribute to the development of obesity is the damage of the blood-brain barrier (BBB) at the median eminence-arcuate nucleus (ME-ARC) interface; however, how the hypothalamic BBB is affected in the offspring of obese mothers requires further investigation.

Loss of dental tissue after restoration or sealing of occlusal carious lesions: 3-4-year results of randomized clinical trials.

Context: Although preservation of the tooth structure is quoted as the main advantage of sealing of carious lesions, there are no long-term studies comparing the maintenance of dental tissue after restoration or after caries sealing.

Aim: To measure the radiographically visible loss of dental tissue after conventional restoration and sealing of carious lesions.

Subjects And Methods: This study was a secondary analysis of two randomized controlled clinical trials, one conducted in Brazil and another in Belgium, which evaluated two different therapies for the treatment of occlusal carious lesions in permanent teeth: sealant (SE) without previous carious tissue removal or restoration (RE) with total removal of carious dentin.

Arcuate Nucleus Overexpression of NHLH2 Reduces Body Mass and Attenuates Obesity-Associated Anxiety/Depression-like Behavior.

Nescient helix-loop-helix 2 (NHLH2) is a hypothalamic transcription factor that controls the expression of prohormone convertase 1/3, therefore having an impact on the processing of proopiomelanocortin and thus on energy homeostasis. Studies have shown that KO of results in increased body mass, reduced physical activity, and hypogonadism. In humans, a polymorphism of the gene is associated with obesity; and in Prader-Willi syndrome, a condition characterized by obesity, hypogonadism and behavioral abnormalities, the expression of NHLH2 is reduced.

Surveillance Bronchoscopy in Lung Transplantation Recipients: A Single Center Experience Analysis.

Bronchoscopy with bronchoalveolar lavage and transbronchial biopsy is the gold standard for the diagnosis of infection or acute cellular rejection in lung transplantation (LTx) recipients, but there is some controversy to perform it in asymptomatic patients. We conducted a retrospective analysis of medical reports of LTx recipients who survived in the first year after transplant during the period of August 2003 to February 2018 to evaluate the applicability of this procedure in the management of asymptomatic acute cellular rejection in our center. We assessed 1252 bronchoscopies of 247 patients during this period, and, facing the histopathological results, we defined our management that included conservative or intervention therapy.

Interleukin-17 acts in the hypothalamus reducing food intake.

Interleukin-17 (IL-17) is expressed in the intestine in response to changes in the gut microbiome landscape and plays an important role in intestinal and systemic inflammatory diseases. There is evidence that dietary factors can also modify the expression of intestinal IL-17. Here, we hypothesized that, similar to several other gut-produced factors, IL-17 may act in the hypothalamus to modulate food intake.

Genomic analysis of reveals the evolutionary dynamics of sex-biased genes in a sequential hermaphrodite fish.

Sexual dimorphism is a fascinating subject in evolutionary biology and mostly results from sex-biased expression of genes, which have been shown to evolve faster in gonochoristic species. We report here genome and sex-specific transcriptome sequencing of , a sequential hermaphrodite fish. Evolutionary comparative analysis reveals that sex-biased genes in are similar in number and function, but evolved following strikingly divergent patterns compared with gonochoristic species, showing overall slower rates because of stronger functional constraints.

Genetics of resistance to photobacteriosis in gilthead sea bream (Sparus aurata) using 2b-RAD sequencing.

Background: Photobacteriosis is an infectious disease developed by a Gram-negative bacterium Photobacterium damselae subsp. piscicida (Phdp), which may cause high mortalities (90-100%) in sea bream. Selection and breeding for resistance against infectious diseases is a highly valuable tool to help prevent or diminish disease outbreaks, and currently available advanced selection methods with the application of genomic information could improve the response to selection.

Intercalation of metformin into montmorillonite.

Metformin hydrochloride is an extensively used antidiabetic drug that according to the results reported here is able to spontaneously intercalate layered silicates like the montmorillonite clay mineral following an ion-exchange mechanism. The adsorption isotherm from water solutions shows a great affinity of metformin towards the clay mineral, which can retain about thrice the exchange capacity of the clay. The adsorbed excess was easily removed by washing with water, leading to an intercalation compound that contains 93 meq of metformin per 100 g of montmorillonite, matching the CEC value of this clay.
