Low-Complexity Timing Correction Methods for Heart Rate Estimation Using Remote Photoplethysmography.

With the rise of modern healthcare monitoring, heart rate (HR) estimation using remote photoplethysmography (rPPG) has gained attention for its non-contact, continuous tracking capabilities. However, most HR estimation methods rely on stable, fixed sampling intervals, while practical image capture often involves irregular frame rates and missing data, leading to inaccuracies in HR measurements. This study addresses these issues by introducing low-complexity timing correction methods, including linear, cubic, and filter interpolation, to improve HR estimation from rPPG signals under conditions of irregular sampling and data loss.

Understanding paralogous epilepsy-associated GABA receptor variants: Clinical implications, mechanisms, and potential pitfalls.

Recent discoveries have revealed that genetic variants in γ-aminobutyric acid type A (GABA) receptor subunits can lead to both gain-of-function (GOF) and loss-of-function (LOF) receptors. GABA receptors, however, have a pseudosymmetrical pentameric assembly, and curiously diverse functional outcomes have been reported for certain homologous variants in paralogous genes (paralogous variants). To investigate this, we assembled a cohort of 11 individuals harboring paralogous M1 proline missense variants in , , and Seven mutations (α1, α1, β2, β3, β3, γ2, and γ2) in α1β2/3γ2 receptors were analyzed using electrophysiological examinations and molecular dynamics simulations.

[The Research Progress in the Diagnosis and Treatment of Primary Intestinal Diffuse Large B-cell Lymphoma--Review].

Primary intestinal diffuse large B-cell lymphoma (PI-DLBCL) is clinically rare, but in recent years, with the gradual maturity of pathology and molecular biology technology, its incidence rate and diagnosis rate have also increased. Due to the lack of specificity of the clinical symptoms of PI-DLBCL, it is easy to misdiagnose and miss the diagnosis, and there is no consensus on the best treatment of PI-DLBCL in clinical practice. Therefore, by retrieving the latest literature at home and abroad, this review systematically discusses the pathogenesis, clinical manifestations, diagnostic criteria, treatment and prognosis of PI-DLBCL, in order to improve the understanding of rare PI-DLBCL in hematology and oncology, and provide reference for basic research and clinical diagnosis and treatment of PI-DLBCL.

Synthesis and characterization of targeted 17β-hydroxysteroid dehydrogenase type 7 inhibitors.

Sex steroid hormones such as estrogen estradiol (E2) and androgen dihydrotestosterone (DHT) are involved in the development of hormone-dependent cancers. Blockade of 17β-hydroxysteroid dehydrogenase type 7 (17β-HSD7), a member of the short chain dehydrogenase/reductase superfamily, is thought to decrease E2 levels while increasing those of DHT. Therefore, its unique double action makes this enzyme as an interesting drug target for treatment of breast cancer.

Clinical significance of prostate cancer identified by transperineal standard template biopsy in men with nonsuspicious multiparametric magnetic resonance imaging.

Objective: Multiparametric magnetic resonance imaging (mpMRI) of the prostate has excellent sensitivity in detecting clinically significant prostate cancer (csCaP). However, whether a negative mpMRI in patients with a clinical suspicion of CaP can omit a confirmatory biopsy remains less understood and without consensus. Transperineal (TP) standard template biopsy (SBx) provides an effective approach to CaP detection.

A Nickel Anchored Covalent Organic Framework as Unimolecular Metallaphotocatalyst for Visible Light Driver C-P Bond Coupling Reaction.

The urgent need to develop a sustainable and environmentally friendly method for synthesizing organophosphine compounds is underscored by their extensive applications in organic synthesis, coordination chemistry, medicinal chemistry, and photoelectric materials.

Correlations of receptor desensitization of gain-of-function GABRB3 variants with clinical severity.

Genetic variants associated with developmental and epileptic encephalopathies have been identified in the GABRB3 gene that encodes the β3 subunit of GABAA receptors. Typically, variants alter receptor sensitivity to GABA resulting in either gain- or loss-of-function, which correlates with patient phenotypes. However, it is unclear how another important receptor property, desensitization, contributes to the greater clinical severity of gain-of-function variants.
