Update on MR Imaging Techniques of the Hip.

MR imaging protocols and technical parameters should be optimized in order to achieve the best diagnostic results. Routine hip MR imaging includes a combination of T1-weighted and fluid-sensitive sequences, obtained in coronal, axial, and sagittal planes. MR arthrography of the hip can be used for assessment of intra-articular pathology involving intricate and signal-poor structures such as articular cartilage, labral fibrocartilage, and intra-articular bodies.

RAD51 separation of function mutation disables replication fork maintenance but preserves DSB repair.

Homologous recombination (HR) protects replication forks (RFs) and repairs DNA double-strand breaks (DSBs). Within HR, BRCA2 regulates RAD51 via two interaction regions: the BRC repeats to form filaments on single-stranded DNA and exon 27 (Ex27) to stabilize the filament. Here, we identified a RAD51 S181P mutant that selectively disrupted the RAD51-Ex27 association while maintaining interaction with BRC repeat and proficiently forming filaments capable of DNA binding and strand invasion.

Chemoenzymatic Measurement of LacNAc in Single-Cell Multiomics Reveals It as a Cell-Surface Indicator of Glycolytic Activity of CD8 T Cells.

Despite the rich information about the physiological state of a cell encoded in the dynamic changes of cell-surface glycans, chemical methods to capture specific glycan epitopes at the single-cell level are quite limited. Here, we report a chemoenzymatic method for the single-cell detection of N-acetyllactosamine (LacNAc) by labeling LacNAc with a specific DNA barcode. The chemoenzymatic labeling does not alter the transcriptional status of immune cells and is compatible with multiple scRNA-seq platforms.

Changes in migraine interictal burden following treatment with galcanezumab: Results from a phase III randomized, placebo-controlled study.

Objective: To evaluate changes in interictal burden with galcanezumab versus placebo in patients with episodic (EM) or chronic migraine (CM).

Background: The disruptive effects of migraine occur both during attacks (ictal period) and between attacks (interictal period), affecting work, school, family, and social life. Migraine clinical trials typically assess ictal burden endpoints, neglecting interictal burden.

NFATc1 marks articular cartilage progenitors and negatively determines articular chondrocyte differentiation.

The origin and differentiation mechanism of articular chondrocytes remain poorly understood. Broadly, the difference in developmental mechanisms of articular and growth-plate cartilage is still less elucidated. Here, we identified that the nuclear factor of activated T-cells cytoplasmic 1 (NFATc1) is a crucial regulator of articular, but not growth-plate, chondrocyte differentiation during development.

Large-scale sequencing identifies multiple genes and rare variants associated with Crohn's disease susceptibility.

Genome-wide association studies (GWASs) have identified hundreds of loci associated with Crohn's disease (CD). However, as with all complex diseases, robust identification of the genes dysregulated by noncoding variants typically driving GWAS discoveries has been challenging. Here, to complement GWASs and better define actionable biological targets, we analyzed sequence data from more than 30,000 patients with CD and 80,000 population controls.

StarD13 negatively regulates invadopodia formation and invasion in high-grade serous (HGS) ovarian adenocarcinoma cells by inhibiting Cdc42.

Metastasis remains the main challenge to overcome for treating ovarian cancers. In this study, we investigate the potential role of the Cdc42 GAP StarD13 in the modulation of cell motility, invasion in ovarian cancer cells. StarD13 depletion does not affect the 2D motility of ovarian cancer cells.

The Spatiotemporal Expression of Notch1 and Numb and Their Functional Interaction during Cardiac Morphogenesis.

Numb family proteins (NFPs), including Numb and Numblike (Numbl), are commonly known for their role as cell fate determinants for multiple types of progenitor cells, mainly due to their function as Notch inhibitors. Previous studies have shown that myocardial NFP double knockout (MDKO) hearts display an up-regulated Notch activation and various defects in cardiac progenitor cell differentiation and cardiac morphogenesis. Whether enhanced Notch activation causes these defects in MDKO is not fully clear.

Glycans From Distinct Genotypes Share Structural and Serological Similarities to Glucuronoxylomannan.

The cell wall is a ubiquitous structure in the fungal kingdom, with some features varying depending on the species. Additional external structures can be present, such as the capsule of (), its major virulence factor, mainly composed of glucuronoxylomannan (GXM), with anti-phagocytic and anti-inflammatory properties. The literature shows that other cryptococcal species and even more evolutionarily distant species, such as the , and can produce GXM-like polysaccharides displaying serological reactivity to GXM-specific monoclonal antibodies (mAbs), and these complex polysaccharides have similar composition and anti-phagocytic properties to cryptococcal GXM.

Characterization of chemotherapy-induced peripheral neuropathy using patient-reported outcomes and quantitative sensory testing.

Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, debilitating side effect in cancer survivors. This study aimed to assess the characteristics of quantitative sensory testing (QST) and its correlation with patient-reported outcomes (PROs) in cancer patients with and without CIPN.

Methods: We conducted a cross-sectional analysis using baseline data from two clinical trials in solid tumor cancer survivors with no CIPN symptoms rated < 2 on a 0-10 Numerical Rating Scale (NRS) or moderate-to-severe CIPN rated ≥ 4 on the NRS.

Understanding the Targeting Mechanisms of Multi-Specific Biologics in Immunotherapy with Multiscale Modeling.

Immunotherapeutics are frequently associated with adverse side effects due to the elicitation of global immune modulation. To lower the risk of these side effects, recombinant DNA technology is employed to enhance the selectivity of cell targeting by genetically fusing different biomolecules, yielding new species referred to as multi-specific biologics. The design of new multi-specific biologics is a central challenge for the realization of new immunotherapies.

An iterative approach to detect pleiotropy and perform Mendelian Randomization analysis using GWAS summary statistics.

Motivation: The overall association evidence of a genetic variant with multiple traits can be evaluated by cross-phenotype association analysis using summary statistics from genome-wide association studies. Further dissecting the association pathways from a variant to multiple traits is important to understand the biological causal relationships among complex traits.

Results: Here, we introduce a flexible and computationally efficient Iterative Mendelian Randomization and Pleiotropy (IMRP) approach to simultaneously search for horizontal pleiotropic variants and estimate causal effect.

Differential regulation of rho GTPases during lung adenocarcinoma migration and invasion reveals a novel role of the tumor suppressor StarD13 in invadopodia regulation.

Background: Lung cancer is the second most commonly occurring cancer. The ability to metastasize and spread to distant locations renders the tumor more aggressive. Members of the Rho subfamily of small GTP-binding proteins (GTPases) play a central role in the regulation of the actin cytoskeleton and in cancer cell migration and metastasis.
