Objective: Epilepsy is a common neurological disease affecting nearly 1% of the global population, and temporal lobe epilepsy (TLE) is the most common type. Patients experience recurrent seizures and chronic cognitive deficits that can impact their quality of life, ability to work, and independence. These cognitive deficits often extend beyond the temporal lobe and are not well understood.

Background: Transgender and gender diverse (TGD) people seek gender-affirming care at any age to manage gender identities or expressions that differ from their birth gender. Gender-affirming hormone treatment (GAHT) and gender-affirming surgery may alter reproductive function and/or anatomy, limiting future reproductive options to varying degrees, if individuals desire to either give birth or become a biological parent.
Objective And Rationale: TGD people increasingly pursue help for their reproductive questions, including fertility, fertility preservation, active desire for children, and future options.

The Jezero crater floor features a suite of related, iron-rich lavas that were examined and sampled by the Mars 2020 rover Perseverance, and whose textures, minerals, and compositions were characterized by the Planetary Instrument for X-ray Lithochemistry (PIXL). This suite, known as the Máaz formation (fm), includes dark-toned basaltic/trachy-basaltic rocks with intergrown pyroxene, plagioclase feldspar, and altered olivine and overlying trachy-andesitic lava with reversely zoned plagioclase phenocrysts in a K-rich groundmass. Feldspar thermal disequilibrium textures indicate that they were carried from their crustal staging area.

Purpose: To evaluate the clinical performance of expanded non-invasive prenatal testing (NIPT-plus) and compare its effectiveness in screening for chromosomal aneuploidies with that of NIPT.
Methods: Screening results, confirmatory invasive testing results, and follow-up data from pregnant women who underwent either NIPT (6792 cases) or NIPT-Plus (5237 cases) testing at Luohe Central Hospital, China, from January 2019 to June 2023 were collected. The positive predictive value (PPV), sensitivity, specificity, and other indicators for different types of chromosomal abnormalities in NIPT/NIPT-plus screening were calculated.

SOX9 is a crucial transcriptional regulator of cartilage development and homeostasis. Dysregulation of is associated with a wide spectrum of skeletal disorders, including campomelic dysplasia, acampomelic campomelic dysplasia, and scoliosis. Yet how variants contribute to the spectrum of axial skeletal disorders is not well understood.

Background: Direct oral anticoagulants (DOACs) can interfere with coagulation analyses, causing erroneous results such as false-positive lupus anticoagulant and false-normal antithrombin, threatening patient safety when overlooked. A test using a prothrombin time quotient method to detect DOAC presence in plasma samples is now commercially available, the MRX PT DOAC, with the result expressed as Clot Time Ratio (CTR).
Objectives: Evaluate the ability of MRX PT DOAC to identify interfering apixaban or rivaroxaban concentrations, identify non-interfering or interfering patient samples, and detect whether a patient is on DOAC treatment.

Targeted therapies and immunotherapies have shown great promise as best-in-class treatments for several cancers with respect to efficacy and safety. While liver test abnormalities are rather common in patients treated with kinase inhibitors or immunotherapy, events of severe hepatotoxicity in these patients are rare in comparison with those associated with chemotherapeutics. The underlying mechanisms and risk factors for severe hepatotoxicity with novel oncology therapies are not well understood, complicating the drug-induced liver injury (DILI) risk assessment in the preclinical and clinical phases of drug development.

Immobility of flowering plants requires them to engage pollen vectors to outcross, introducing considerable inefficiency in the conversion of pollen production into sired seeds. Whether inefficiencies influence the evolution of the relative resource allocation to female and male functions has been debated for more than 40 years. Whereas early models suggested no effect, negative interspecific relations of mean pollen production and pollen : ovule ratios to the proportion of removed pollen that is exported to stigmas (pollen-transfer efficiency) indicate otherwise.

Purpose: Ultra-high translucency zirconia (UT-Zr) is known for its high esthetic quality; however, its inert surface results in low hydrophilicity and surface energy (SE). To address this limitation, this study proposes an innovative zirconia heat treatment process (ZHTP) and aims to evaluate the effects of ZHTP on the surface characteristics of UT-Zr, offering a novel and practical approach for surface pretreatment in dental practice.
Material And Methods: The plate-shaped UT-Zr samples were fabricated.

Behavioral and psychological symptoms of dementia (BPSD), such as agitation, apathy, and psychosis, are highly prevalent and have a significant impact on patients and their care partners. The neurobiology of BPSD involves a complex interplay of structural brain changes and alterations in the neurotransmitter system. Various genetic and plasma biomarkers have also been studied.

The cytoskeleton, composed of microtubules, intermediate filaments and actin filaments is vital for various cellular functions, particularly within the nervous system, where microtubules play a key role in intracellular transport, cell morphology, and synaptic plasticity. Tubulin-specific chaperones, including tubulin folding cofactors (TBCA, TBCB, TBCC, TBCD, TBCE), assist in the proper formation of α/β-tubulin heterodimers, essential for microtubule stability. Pathogenic variants in these chaperone-encoding genes, especially TBCD, have been linked to Progressive Encephalopathy with Brain Atrophy and Thin Corpus Callosum (PEBAT, OMIM #604,649), a severe neurodevelopmental disorder.

Little is known about how patients with antiphospholipid syndrome (APS) or antiphospholipid antibodies (aPL) access and trust health information. This research aimed to: describe the sources of information most frequently accessed/trusted by patients with APS/aPL; identify if individuals with APS/aPL perceived their health had been negatively impacted by various sources and document obstacles to accessing health information. Patients meeting Revised Sapporo Criteria for APS or with ≥1 positive aPL on ≥2 occasions were recruited to an online survey regarding their health information use at diagnosis and within 6 months preceding survey completion.
