Metformin, a first-line oral antidiabetic agent that has shown promising results in terms of treating childhood and adolescent obesity, might influence the composition of the gut microbiota. We aimed to evaluate whether the gut microbiota of non-diabetic children with obesity changes after a metformin intervention.

The study was a multicenter and double-blind randomized controlled trial in 160 children with obesity. Children were randomly assigned to receive either metformin (1 g/day) or placebo for 6 months in combination with healthy lifestyle recommendations in both groups. Caerulein ic50 Then, we conducted a metagenomic analysis in a subsample obtained from 33 children (15 metformin, 18 placebo). A linear mixed-effects model (LMM) was used to determine the abundance changes from baseline to six months according to treatment. To analyze the data by clusters, a principal component analysis was performed to understand whether lifestyle habits have a different influence on the microbiota depending on the treatment group.er 2011.In the last years, clusterin, a challenging and paradoxical apolipoprotein, has been of growing interest amongst a rising number of scientists. This enigmatic protein is present in all fluids of the organism besides within the intracellular matrix, and it plays diverse, and at times contrary, roles in a growing number of pathologies. It seems to vary its location and function to assure cellular survival being cytoprotective hence its significance in neuroprotection and cancer along with chemotherapy resistance. However, it can also lead to cellular arrest and its modulation to apoptosis. Additionally, it has been described to modulate pain, as well as linked to inflammation, cardioprotection, satiety and hunger, and possibly to addictive behaviour development. Thus, it has been postulated to be used both as a biomarker and a very explorable new therapeutic target for several conditions.Cancer metastasis is one of the foremost causes of cancer incidence and fatality in the whole of the world. Circulating tumor cells (CTC) have been confirmed to be among the most significant stimuli of metastasis in recent years and presently are the subject of extensive research aiming to be accurately identified by using biological and physical properties. Among the various studies conducted for isolation, identification, and characterization of CTCs, microfluidic systems have aroused great attention owing to their unique advantages such as low-cost, simplicity, reduction in reagent consumption, miniaturization, fast and precise control. The purpose of this review is to provide an overview of current state of the microfluidic biosensors for the screening of CTCs. Additionally, given the recent progress in this field, future outlook for the development of the microfluidics biosensing is briefly discussed.Currently, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) were approved for the treatment of non-small cell lung cancer (NSCLC) patients harboring EGFR mutation. However, some lung cancer patients fail to respond and eventually develop drug resistance. Therefore, new therapeutic strategies are needed to improve the outcomes for substantial clinical benefit. Here we aimed to explore the combination of vinorelbine with the second EGFR-TKI afatinib in NSCLC cells with or without EGFR mutation. The three cells of H1975, HCC827, and H460 were assessed for the combination of vinorelbine and afatinib. Vinorelbine combined with afatinib synergistically inhibited the three lung cancer cells growth without aggravating adverse effect on the normal lung cells. The combination of low doses of vinorelbine and afatinib suppressed the cancer cell proliferation by cell colony formation assay and significantly induced cell apoptosis. The anti-apoptotic proteins Bcl-xL and Bcl-2 showed significant reduction after the drug combination treatment, while the pro-apoptotic protein Bax as well as apoptosis indicators cytochrome C and cleaved PARP were observed a notable increasing. EGFR downstream pathways including AKT, ERK, JNK, and p38 were highly active and p53 was inactive in the three lung cancer cells, favoring tumor growth. The low doses of vinorelbine plus afatinib blocked the phosphorylation of AKT, ERK, JNK, and p38, but restored the expression of p53. Our findings suggested that the combination of vinorelbine and afatinib could be recommended as a therapeutic regimen for treatment of NSCLC with or without EGFR mutation.Artificial sunscreens are already gaining traction in order to protect the skin from sunburns, photoaging and photocarcinogenesis. However, the efficacy and safety of most artificial sunscreen constituents are hindered by their photostability, toxicity and damage to marine ecosystems. Natural selection and evolution have ensured that plants and animals have developed effective protective mechanisms against the deleterious side effects of oxidative stress and ultraviolet radiation (UV). Hence, natural antioxidants such as sun blockers are drawing considerable attention. The exact mechanism by which natural components act as sunscreen molecules has not been clearly established. However, conjugated π system is reported to play an important role in protecting the vital genetic material within the organism. Compared to artificial sunscreens, natural sunscreens with strong UV absorptive capacities are largely limited by low specific extinction value and by their inability to spread in large-scale sunscreen cosmeticF values. Although the photoprotective effects of natural components have been established, their deleterious side effects have not been elucidated.The successful resolution of ever-changing conflicting contexts requires efficient cognitive control. Previous studies have found similar neural patterns in conflict processing for different modalities using an event-related potential (ERP) approach and have concluded that cognitive control is supramodal. However, recent behavioral studies have found that conflict adaptation (a phenomenon with the reduction of congruency effect in the current trial after an incongruent trial as compared with a congruent trial) could not transfer across visual and auditory modalities and suggested that cognitive control is modality-specific, challenging the supramodal view. These discrepancies may have also arisen from methodological differences across studies. The current study examined the electroencephalographic profiles of a Stroop-like task to elucidate the modality-specific neural mechanisms of cognitive control. Participants were instructed to respond to a target always coming from the visual modality while disregarding the distractor coming from either the auditory or the visual modality.
