Adaptation of maxillary removable partial denture frameworks fabricated with a direct digital workflow: A randomized crossover clinical trial.

Objectives: To compare the adaptation of maxillary removable partial denture (RPD) frameworks fabricated through direct digital workflows with that of traditional cast frameworks and indirect digital frameworks.

Methods: The workflow for fabricating the digital cobalt-chromium framework encompassed intraoral scanning (IOS) using Trios 3, computer-aided survey and design, and subsequently either the lost-wax technique from a printed resin framework pattern (Framework B) or direct selective laser melting (SLM) (Framework C). The traditional cast framework (Framework A) was selected as a control.

Structural insights into HIV-2 CA lattice formation and FG-pocket binding revealed by single-particle cryo-EM.

One of the striking features of human immunodeficiency virus (HIV) is the capsid, a fullerene cone comprised of pleomorphic capsid protein (CA) that shields the viral genome and recruits cofactors. Despite significant advances in understanding the mechanisms of HIV-1 CA assembly and host factor interactions, HIV-2 CA assembly remains poorly understood. By templating the assembly of HIV-2 CA on functionalized liposomes, we report high-resolution structures of the HIV-2 CA lattice, including both CA hexamers and pentamers, alone and with peptides of host phenylalanine-glycine (FG)-motif proteins Nup153 and CPSF6.

A forward genetic screen identifies potassium channel essentiality in SHH medulloblastoma maintenance.

Distinguishing tumor maintenance genes from initiation, progression, and passenger genes is critical for developing effective therapies. We employed a functional genomic approach using the Lazy Piggy transposon to identify tumor maintenance genes in vivo and applied this to sonic hedgehog (SHH) medulloblastoma (MB). Combining Lazy Piggy screening in mice and transcriptomic profiling of human MB, we identified the voltage-gated potassium channel KCNB2 as a candidate maintenance driver.

Risk of clinically significant prostate cancer undercategorized by multiparametric magnetic resonance imaging.

Background: To investigative potential clinicopathological characteristics and imaging-related risk factors of clinically significant prostate cancer (csPCa) undercategorized in patients with negative or equivocal MRI.

Methods: This retrospective study included 581 patients with pathologically confirmed csPCa (Gleason score ≥ 3 + 4), including 108 undercategorized csPCa and 473 detected csPCa. All patients underwent multiparametric MRI (mpMRI).

Quantitative Trait Loci Identification and Candidate Genes Characterization for Indole-3-Carbinol Content in Seedlings of .

is a member of the cruciferous family with rich glucosinolate (GSL) content, particularly glucobrassicin (3-indolylmethyl glucosinolate, I3M), that can be metabolized into indole-3-carbinol (I3C), a compound with promising anticancer properties. To unravel the genetic mechanism influencing I3C content in rapeseed seedlings, a comprehensive study was undertaken with a doubled haploid (DH) population. By quantitative trait loci (QTL) mapping, seven QTL that were located on A01, A07, and C04 were identified, with the most significant contribution to phenotypic variation observed on chromosome A07 (11.
