Multiple comparison

Constitutional heterozygous pathogenic variants in the exonuclease domain of POLE and POLD1, which affect the proofreading activity of the corresponding polymerases, cause a cancer predisposition syndrome characterized by increased risk of gastrointestinal polyposis, colorectal cancer, endometrial cancer and other tumor types. The generally accepted explanation for the connection between the disruption of the proofreading activity of polymerases epsilon and delta and cancer development is through an increase in the somatic mutation rate...

The occlusion bodies of Autographa californica multiple nucleopolyhedrovirus are proteinaceous formations with significant biotechnological potential owing to their capacity to integrate foreign proteins through fusion with polyhedrin, their primary component. However, the strategy for successful heterologous protein inclusion still requires further refinement. In this study, we conducted a comparative assessment of various conditions to achieve the embedding of recombinant proteins within polyhedra. Two baculoviruses were constructed: AcPHGFP (polh+), with GFP as a fusion to wild type (wt) polyhedrin and AcΔPHGFP (polh+), with GFP fused to a fragment corresponding to amino acids 19 to 110 of polyhedrin...

OBJECTIVE: To reduce health inequities it is important to identify intersections in characteristics of individuals subject to privilege or disadvantage. Different proposals for that have recently been published. One approach (1) considers models specified with 1st and all 2nd -order effects and another (2) the stratification based on multiple covariates; both categorize continuous covariates. A simulation study was conducted in order to review both methods with regard to identification of intersections showing true differences, rate of false positive results, and generalizability to independent data compared to an established approach (3) of backward variable elimination according to Bayesian information criterium (BE-BIC) combined with splines...

PURPOSE: To evaluate and compare the difference in retention between implant-supported restorations with and without surface modification of the implant abutments. MATERIALS AND METHODS: A total of 30 patients with singletooth implants were restored with cement-retained (Multilink N, Ivoclar) restorations using titanium base abutments (Variobase, Straumann) and randomly assigned surface modifications. Group 1 used nonmodified abutments, group 2 used sandblasted abutments, and group 3 used sandblasted abutments followed by an application of metal primer...

OBJECTIVE: This study evaluated the surface roughness, wettability and adhesion of multispecies biofilms (Candida albicans, Staphylococcus aureus and Streptococcus mutans) on 3D-printed resins for complete denture bases and teeth compared to conventional resins (heat-polymerized acrylic resin; artificial pre-fabricated teeth). METHODOLOGY: Circular specimens (n=39; 6.0 mm Ø × 2.0 mm) of each group were subjected to roughness (n=30), wettability (n=30) and biofilm adhesion (n=9) tests...

Scaled interventions are required to address levels of overweight and obesity and reduce health inequalities. Little data is available on the effectiveness of community weight management programmes for participants self-selecting to attend across different socio-economic backgrounds. This analysis investigates 3, 6, and 12-month outcomes of adults joining a real-life community weight management programme. Weight, attendance and Indices of Multiple Deprivation (IMD) data from all fee-paying adults joining Slimming World in 2016 were collated...

For many years, multi-scale models of chromatin domains, such as A/B compartments, sub-compartments, topologically associated domains (TADs), sub-TADs, and loops have been popular. However, existing methods can only identify structures at a single scale and cannot partition multi-scale structures. In this paper, we proposed a method (TORNADOES) for chromatin domain partitioning based on hypergraph clustering. First, we use a density clustering algorithm to identify TADs at different scales based on Hi-C data with different resolutions...

BACKGROUND: Nucleus replacement devices (NRDs) are not routinely used in clinic, predominantly due to the risk of device expulsion. Rigorous in vitro testing may enable failure mechanisms to be identified prior to clinical trials; however, current testing standards do not specify a particular expulsion test. Multiple methods have therefore been developed, complicating comparisons between NRD designs. Thus, this study assessed the effectiveness of four previously reported expulsion testing protocols; hula-hoop (Protocol 1), adapted hula-hoop (Protocol 2), eccentric cycling (Protocol 3), and ramp to failure (Protocol 4), applied to two NRDs, one preformed and one in situ curing...

BACKGROUND: Opioids form the basis of perioperative pain management but are associated with multiple side effects. In opioid-free anesthesia (OFA), several non-opioid drugs or neuraxial/regional blocks are used as substitutes for opioids. Ketamine, a N-methyl-d-aspartate antagonist, provides intense analgesia. However, there is a shortage of literature on the effects of ketamine-based OFA on hemodynamics (HD) and postoperative analgesia in patients undergoing thoracolumbar spine surgery...

INTRODUCTION: Gender bias impacts the promotion and tenure of female emergency medicine (EM) physicians and limits their ability to advance in academic rank. Many factors influence the promotion and tenure process including research, evaluations, opportunities for leadership, sponsorship, and mentorship. The goal of this study is to determine if resident evaluations of EM faculty differ by faculty gender. METHODS: A quantitative analysis was used to examine 14,613 teaching evaluations of faculty by residents at a single academic center (The Ohio State University Wexner Medical Center, Columbus) in the years 2017-2019...

BACKGROUND: Multiple sclerosis (MS) is divided into three clinical phenotypes: relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), and primary progressive MS (PPMS). It is unknown to what extent SPMS and PPMS pathophysiology share inflammatory or neurodegenerative pathological processes. Cerebrospinal (CSF) neurofilament light (NfL) has been broadly studied in different MS phenotypes and is a candidate biomarker for comparing MS subtypes. RESEARCH QUESTION: Are CSF NfL levels different among clinical subtypes of progressive MS? METHODS: A search strategy identifying original research investigating fluid neurodegenerative biomarkers in progressive forms of MS between 2010 and 2022 was applied to Medline...

BACKGROUND: The influence of mindfulness-based intervention (MBI) programs on behavioural problems among community youth is largely understudied. While technology continues to evolve and the prevalence of screen-based activities is rising, limited studies have accounted for screen time when examining the efficacy of an MBI. Accordingly, this study investigated the impact of MBI on conduct problems and hyperactivity among community youth, accounting for sociodemographic characteristics and four types of screen time...

OBJECTIVE: Hematoma expansion (HE) predicts disability and death after acute intracerebral hemorrhage (ICH). Aspirin and anticoagulants have been associated with HE. We tested the hypothesis that P2Y12 inhibitors predict subsequent HE in patients. We explored laboratory measures of P2Y12 inhibition and dual antiplatelet therapy with aspirin (DAPT). METHODS: We prospectively identified patients with ICH. Platelet activity was measured with the VerifyNow-P2Y12 assay...

PURPOSE: The purpose of this in vitro study was to evaluate the effect of substrate material and abutment geometry on the accuracy of digital casts obtained by intraoral scanning. MATERIAL AND METHODS: The height and total occlusal convergence (TOC) angle were measured in 5 different groups that contained 5 specimens of different materials: natural tooth, cobalt chromium alloy, titanium, zirconium dioxide ceramic, and resin...

Accurate degradation trend prediction (DTP) is crucial for optimizing equipment operation and maintenance, thereby boosting production efficiency. This study introduces a novel Data Repair and Dual-data-stream LSTM (DR-DLSTM) network to tackle the challenge of missing data in equipment DTP. The proposed DR-DLSTM framework employs convex optimization to consider both the trend and periodic variations in the data, incorporating polynomial and trigonometric functions into the implicit feature matrix to construct latent vectors for missing data rectification...

Genome-wide Association Studies (GWAS) methods have identified individual single-nucleotide polymorphisms (SNPs) significantly associated with specific phenotypes. Nonetheless, many complex diseases are polygenic and are controlled by multiple genetic variants that are usually non-linearly dependent. These genetic variants are marginally less effective and remain undetected in GWAS analysis. Kernel-based tests (KBT), which evaluate the joint effect of a group of genetic variants, are therefore critical for complex disease analysis...

BACKGROUND: Fecal samples are commonly used for longitudinal studies of the gut lumen microbiome to track the course of response to infection or drug treatment, but no comparable method has been evaluated for longitudinal analysis of the gastric lumen microbiome in mice. Herein, a buffer flush of the stomach with a flexible gavage needle was used to collect gastric contents at one or several time points without harming the mouse. These samples were compared to samples collected by sacrifice and dissection of the mouse stomach...
