Comparative evaluation of bone density after implant placement using cone-beam CT analysis in augmented versus non-augmented.

Introduction: Dental implants are the most popular alternative to rehabilitation of missing teeth and oro-facial structures. The outcome of such procedures depends on various factors and most-importantly on the osseo-integation with the surrounding bone. The evaluation needs better visualization and evaluation using CBCT anaylsis and determination of HU, using an appropriate software.

Multi-Omics Analysis for Identifying Cell-Type-Specific Druggable Targets in Alzheimer's Disease.

Background: Analyzing disease-linked genetic variants via expression quantitative trait loci (eQTLs) is important for identifying potential disease-causing genes. Previous research prioritized genes by integrating Genome-Wide Association Study (GWAS) results with tissue- level eQTLs. Recent studies have explored brain cell type-specific eQTLs, but they lack a systematic analysis across various Alzheimer's disease (AD) GWAS datasets, nor did they compare effects between tissue and cell type levels or across different cell type-specific eQTL datasets.

Low dose DNA methyltransferase inhibitors potentiate PARP inhibitors in homologous recombination repair deficient tumors.

Background: Poly (ADP-Ribose) polymerase inhibitors are approved for treatment of tumors with BRCA1/2 and other homologous recombination repair (HRR) mutations. However, clinical responses are often not durable and treatment may be detrimental in advanced cancer due to excessive toxicities. Thus we are seeking alternative therapeutics to enhance PARP-directed outcomes.

ERα dysfunction caused by ESR1 mutations and therapeutic pressure promotes lineage plasticity in ER breast cancer.

Multiple next-generation molecules targeting estrogen receptor α (ERα) are being investigated in breast cancer clinical trials, encompassing thousands of women globally. Development of these molecules was partly motivated by the discovery of resistance-associated mutations in ESR1 (encodes ERα). Here, we studied the impact of ERα antagonist/degraders against Esr1 mutations expressed in mouse mammary glands.

The ATP-dependent DEAD-box RNA Helicase Dbp2 regulates the glucose/nitrogen stress response in baker's yeast by modulating reversible nuclear retention and decay of SKS1 mRNA.

In Saccharomyces cerevisiae, SKS1 mRNA encoding a glucose-sensing serine/threonine kinase belongs to "nucleus-retained" (NR) mRNAs representing a subset of otherwise normal transcripts, which exhibits slow nuclear export and excessively long nuclear dwell time. Nuclear retention of the SKS1 mRNA triggered by a 202 nt "export-retarding" nuclear zip code (NZ) element promotes its rapid degradation in the nucleus by the nuclear exosome/CTEXT. In this investigation, we demonstrate that Dbp2p, an ATP-dependent DEAD-box RNA helicase binds to SKS1 and other NR-mRNAs and thereby inhibits their export by antagonizing with the binding of the export factors Mex67p/Yra1p.

Cell Type Differentiation Using Network Clustering Algorithms.

Single cell RNA-seq (scRNA-seq) technologies provide unprecedented resolution representing transcriptomics at the level of single cell. One of the biggest challenges in scRNA-seq data analysis is the cell type annotation, which is usually inferred by cell separation approaches. In-silico algorithms that accurately identify individual cell types in ongoing single-cell sequencing studies are crucial for unlocking cellular heterogeneity and understanding the biological basis of diseases.

Navigating from cellular phenotypic screen to clinical candidate: selective targeting of the NLRP3 inflammasome.

The NLRP3 inflammasome plays a pivotal role in host defense and drives inflammation against microbial threats, crystals, and danger-associated molecular patterns (DAMPs). Dysregulation of NLRP3 activity is associated with various human diseases, making it an attractive therapeutic target. Patients with NLRP3 mutations suffer from Cryopyrin-Associated Periodic Syndrome (CAPS) emphasizing the clinical significance of modulating NLRP3.

A Practical and Metal-Free Approach Towards Synthesis of Spiro-Benzazepinoindole Derivatives via Pentafluorophenol Catalyzed Pictet-Spengler Reaction.

The efficient pentaflurophenol-catalyzed Pictet-Spengler cyclization was carried out which led to the formation of spirobenzazepinoindole. This article examines the methods and modifications of Pictet-Spengler cyclization in the synthesis of intricate organic compounds, emphasizing its significance in drug discovery and development. This reaction generally entails the condensation of an amine with an aldehyde or ketone, succeeded by an intramolecular cyclization step catalyzed by pentafluorophenol, an alternate for metal-mediated catalysts due to its facile characteristics which render it an invaluable asset in organic synthesis and catalysis.

Updated Survival Follow-Up for Phase Ib Trial of the Histone Deacetylase Inhibitor Abexinostat With Pazopanib in Patients With Solid Tumor Malignancies.

Purpose: Histone deacetylase (HDAC) inhibition downregulates hypoxia-inducible factor-1α and modulates multiple metabolomic pathways relevant in cancer. Here we report a potential novel biomarker to predict exceptional responders (>3 years) in patients receiving HDAC and vascular endothelial growth factor (VEGF) inhibition.

Patients And Methods: Patients with solid tumor malignancies were enrolled in this phase Ib trial of abexinostat (4/7 ×21 days) and pazopanib (28/28 days), with a dose expansion in renal cell carcinoma (RCC).

A rapid point-of-care population-scale dipstick assay to identify and differentiate SARS-CoV-2 variants in COVID-19-positive patients.

Delta and Omicron variants of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) are remarkably contagious, and have been recognized as variants of concern (VOC). The acquisition of spontaneous substitutions or insertion-deletion mutations (indels) in the spike protein-encoding gene substantially increases the binding affinity of the receptor binding domain (RBD)-hACE2 complex and upsurges the transmission of both variants. In this study, we analyzed thousands of genome sequences from 30 distinct SARS-CoV-2 variants, focusing on the unique nucleic acid signatures in the spike gene specific to the Delta and Omicron variants.
