In a prospective, single-center, randomized trial, 66 patients with acute coronary syndrome (ACS) and mild dysglycemia (HbA1c 6.0 (5.7, 6.3)%, 58% of impaired glucose tolerance) were randomly assigned to receive alogliptin (n=33) or placebo (n=33) in addition to standard treatments. Serial intravascular ultrasound (IVUS) was performed at baseline and 10 months to evaluate changes in coronary percent plaque volumes (%PV) and plaque tissue components of non-culprit lesions (NCLs).

Baseline clinical and IVUS characteristics, as well as decreases in HbA1c and lipid variables during 10 months, did not differ significantly between the 2 groups. In contrast, with respect to vascular responses, the alogliptin group showed significantly greater decreases in plaque volumes (-0.3±0.6 vs. -0.04±0.7mm
/mm, p= 0.03) and %PV (-0.9±2.8 vs. 1.2±3.6%, p= 0.01), with a tendency toward smaller lumen loss (-0.1± this patients' subset.Recent advances in Deep Learning (DL) fueled the interest in developing neuromorphic hardware accelerators that can improve the computational speed and energy efficiency of existing accelerators. Among the most promising research directions towards this is photonic neuromorphic architectures, which can achieve femtojoule per MAC efficiencies. Despite the benefits that arise from the use of neuromorphic architectures, a significant bottleneck is the use of expensive high-speed and precision analog-to-digital (ADCs) and digital-to-analog conversion modules (DACs) required to transfer the electrical signals, originating from the various Artificial Neural Networks (ANNs) operations (inputs, weights, etc.) in the photonic optical engines. The main contribution of this paper is to study quantization phenomena in photonic models, induced by DACs/ADCs, as an additional noise/uncertainty source and to provide a photonics-compliant framework for training photonic DL models with limited precision, allowing for reducing the need for expensive high precision DACs/ADCs. The effectiveness of the proposed method is demonstrated using different architectures, ranging from fully connected and convolutional networks to recurrent architectures, following recent advances in photonic DL.In this paper, we study the multi-task sentiment classification problem in the continual learning setting, i.e., a model is sequentially trained to classify the sentiment of reviews of products in a particular category. The use of common sentiment words in reviews of different product categories leads to large cross-task similarity, which differentiates it from continual learning in other domains. This knowledge sharing nature renders forgetting reduction focused approaches less effective for the problem under consideration. Unlike existing approaches, where task-specific masks are learned with specifically presumed training objectives, we propose an approach called Task-aware Dropout (TaskDrop) to randomly sample a binary mask for each task. While the standard dropout generates and applies random masks for each training instance per epoch for regularization, random masks in TaskDrop are used for model capacity allocation and reuse to each coming task. We conducted experimental studies on Amazon review data and made comparison to various baselines and state-of-the-art approaches. Our empirical results show that regardless of simplicity, TaskDrop overall achieved competitive performance, especially after relatively long term learning. This demonstrates that the proposed random capacity allocation mechanism works well for continual sentiment classification.The use of vitreous humor (VH) in forensic casework has been growing in the last years due to numerous advantages. Several compounds can be evaluated in this matrix, including benzodiazepines whose determination is essential due to their great availability and potential of dependance and misuse. Postmortem toxicological analyses are required to determine the influence of benzodiazepines in deaths. However, most of the analytical methods which determine these drugs in VH are laborious and time consuming. This article describes a simple method based on protein precipitation for the determination of eight benzodiazepines in VH samples. Samples were prepared through a protein precipitation method and analyzed by liquid chromatography tandem mass spectrometry. Solvent choice and sample and solvent volumes for precipitation were optimized using chemometric approaches. The method was validated for selectivity, lower limit of quantification (LLOQ), linearity, carryover, precision, bias, matrix effect and dilution integrity. In order to verify the applicability, 62 vitreous humor samples were analyzed. LLOQs were 1 ng/mL and calibration curves were linear from 1 to 25 ng/mL (r2 > 0,99) for all analytes. Bias, precision and dilution integrity results were satisfactory according to proper guidelines. Ionization suppression was significant with values ranging from 8 to 37%. Two samples from real cases were positive for diazepam with the following concentrations 6.80 ng/mL and 47.68 ng/mL, approximately 10 times lower than those found in peripheral blood. The procedure described here can be used as a straightforward and low cost method for the quantitation of multiple benzodiazepines in VH.The emergence of a novel coronavirus, COVID-19, in December 2019 led to a global pandemic with more than 170 million confirmed infections and more than 6 million deaths (by July 2022). Studies have shown that infection with SARS-CoV-2 in cancer patients has a higher mortality rate than in people without cancer. Here, we have reviewed the evidence showing that gut microbiota plays an important role in health and is linked to colorectal cancer development. Studies have shown that SARS-CoV-2 infection leads to a change in gut microbiota, which modify intestinal inflammation and barrier permeability and affects tumor-suppressor or oncogene genes, proposing SARS-CoV-2 as a potential contributor to CRC pathogenesis.
Ovarian cancer (OC) is one of the most common gynecological malignancies with a high incidence. Researches showed that lncRNA KCNQ1OT1 (KCNQ1OT1) was involved various tumors progression, including OC. However, the precise mechanism of KCNQ1OT1 in OC needs to be further clarified.

For investigate the underlying mechanism of KCNQ1OT1 regulating OC progression.

CCK-8 assay, colony formation assay, Transwell assay, Western blot and quantitative real-time PCR (qRT-PCR) were performed to examine viability, proliferation, migration and invasion, genes and proteins' level. To identify KCNQ1OT1 as a regulator of miR-125b-5p and miR-125b-5p as a regulator of CD147, we used miRNA target prediction algorithms, Pearson's correlation analysis and dual-luciferase reporter gene assay.

KCNQ1OT1 was high expression and miR-125b-5p was low expression in OC, and KCNQ1OT1 was negatively correlated with that of miR-125b-5p in OC specimens. KCNQ1OT1 promoted OC cell proliferation and metastasis by binding to miR-125b-5p. miR-125b-5p targeted CD147, and which was negatively correlated with that of miR-125b-5p in OC specimens. KCNQ1OT1 was positively correlated with that of CD147 in OC specimens, and KCNQ1OT1 accelerated OC progression via miR-125b-5p/CD147 axis.

KCNQ1OT1 accelerated OC progression via miR-125b-5p/CD147 axis indicating KCNQ1OT1 serve as a novel biomarker for OC treatment. Our research provides a new direction for OC treatment.

Endothelin-1 (ET-1) is a peptide overexpressed in gastric cancer (GC) and linked to carcinogenesis and resistance to chemotherapy. Applying microRNAs (miRNAs/miRs) to downregulate ET-1 and reverse resistance to commonly used chemotherapy drugs such as 5-fluorouracil (5-FU) is practical.

The current study sought to evaluate the miR-648 expression in GC and any plausibility of its replacement, either with or without the combination of chemo agents to downregulate ET-1 expression through interaction with its target gene. To this end, miR-648 and ET-1 expression levels were assessed in GC tissues and adjacent non-tumor tissues driven from 65 patients who had already undergone surgery, fifteen of which had received 5-FU before surgery. The impact of miR-648 and chemo agents on ET-1 expression was measured using qPCR and Western blotting. Further, an MTT assay was conducted to assess its association with cell viability. Ultimately, the association of miR-648 and ET-1 with clinicopathological characteristics wasuppressed ET-1 production, notably when combined with 5-FU, leading to survival reduction. These results further showed that miR-648 replacement could sensitize chemoresistant GC cells. selleck chemical Besides, a significant association between ET-1 and miR-648 with clinicopathological features was discovered CONCLUSIONS miR-648 replacement may serve as a potential oncosuppressive therapeutic approach that warrants further investigation to translate into an effective GC treatment.
To investigate the biological effects of electronic cigarette (e-cigarette) and heated tobacco product extracts respect to tobacco smoke extract on human gingival fibroblasts and human oral keratinocytes analysing cell viability, morphology, migration, apoptosis, cell cycle and epithelial-mesenchymal transition (EMT).

Human gingival fibroblasts and human oral keratinocytes viability was analysed by MTT assay, cell morphology using scanning electron microscope (SEM) and cell migration by Scratch assay, a method that mimics the cell migration during wound healing in vivo. Apoptosis and cell cycle were analysed with flow cytometry and the related-gene expression of TP53, BCL2, CDKN2A and CDKN1A was indagated using real-time polymerase chain reaction. EMT process was analysed through expression of specific markers CDH1, SNAI2, TWIST1, MMP2, FN1 and VIM. All investigations were evaluated after 24h an in vitro exposure.

Undiluted tobacco smoke extract induced significant inhibition of cell viability and cell migration, caused morphological alterations and induced an increase in cell death. No alterations or damage were observed after treatment with e-cigarette extracts. Heated tobacco product extract induced proliferation as highlighted by an increase of cell viability, cell migration and alterations of cycle analysis.

Comparing the different cigarette extracts, tobacco smoke turns out to be the most harmful, e-cigarette did not determine morphological and functional alterations and heated tobacco product must be carefully investigated for its possible clinical effects on oral cell populations.

We aimed to assess the role of interleukin -1 receptor antagonist (IL-1RA) in a ligature-induced periodontal (LIP) model and the mechanism of IL-1RA in regulating the IL-17-mediated periodontal bone loss.

Periodontal bone loss was induced through the LIP model in WT and Il1ra
mice and measured by micro(μ) CT. Transcription of upstream IL-17 production signals and downstream targets in the ligated gingiva was compared by the real-timequantitative PCR (RT-qPCR) between WT and Il1ra
mice. Single-cell suspensions were prepared in gingiva and cervical lymph nodes and were analyzed by fluorescence-activated cell sorting to quantify IL-17
cells and IL-17-secreting subpopulations. We locally delivered an anti-IL-17 neutralizing antibody to the ligated gingiva and compared the bone loss with the isotype control antibody-treated Il1ra
mice.

Il1ra
mice manifested significantly more bone loss than that of WT mice in the LIP model. Il17 and IL-17-associated transcripts (Il1b, Il6, Il23, Tgfb), Inos, Mrc1, Mmp13, and Rank were upregulated in the gingiva of Il1ra
mice in comparison to WT mice.
