Association of estrogen and progesterone receptor polymorphisms with idiopathic thin endometrium.

Pharmacogenet Genomics

January 2025

Reproductive Medicine, Instituto Bernabeu of Fertility and Gynaecology.

The research question is as follows: Are estrogen and progesterone receptor genotypes associated with thin endometrium? We performed a prospective cohort study of 129 patients who underwent preimplantation genetic testing for aneuploidies. These patients were categorized according to endometrial thickness: >7 mm control group (n = 94) and ≤7 mm study group (n = 35). Polymorphisms in the genes ESR1 (rs9340799 and rs3138774), ESR2 (rs1256049 and rs4986938), and PGR (rs1042838) were analyzed.

January 2025

Univ Rennes, CNRS, IPR (Institut de Physique de Rennes) - UMR 6251, F-35000 Rennes, France.

An accurate potential energy model, explicitly designed for studying scattering and treating the spin-orbit and nonadiabatic couplings on an equal footing, is proposed for the S + Ar system. The model is based on the Effective Relativistic Coupling by Asymptotic Representation (ERCAR) approach, building the geometry dependence of the spin-orbit interaction a diabatisation scheme. The resulting full diabatic model is used in close-coupling calculations to compute inelastic scattering cross sections for de-excitation from the S(D) fine structure level into the P multiplet.

The visual system of teleost fish grows continuously, which is a useful model for studying regeneration of the central nervous system. Glial cells are key for this process, but their contribution is still not well defined. We followed oligodendrocytes in the visual system of adult zebrafish during regeneration of the optic nerve at 6, 24, and 72 hours post-lesion and at 7 and 14 days post-lesion via the sox10:tagRFP transgenic line and confocal microscopy.

Introduction: Changes in sleep physiology can predate cognitive symptoms by decades in persons with Alzheimer's disease (AD), but it remains unclear which sleep characteristics predict cognitive and neurodegenerative changes after AD onset.

Methods: Using data from a prospective cohort of mild to moderate AD (n = 60), we analyzed non-rapid eye movement sleep spindles and slow oscillations (SOs) at baseline and their associations with baseline amyloid beta (Aβ) and tau and with cognition from baseline to 3-year follow-up.

Results: Higher spindle and SO activity predicted significant changes in Aβ and tau at baseline, lower Alzheimer's Disease Assessment Scale Cognitive Subscale (better cognitive performance) score, and higher Mini-Mental State Examination score from baseline to 36 months.

Projected changes in moisture sources and sinks affecting the US East Coast and the Caribbean Sea.

Ann N Y Acad Sci

January 2025

Environmental Physics Laboratory (EPhysLab), Centro de Investigación Mariña, Universidade de Vigo, Ourense, Spain.

This study uses a combination of the FLEXPART Lagrangian dispersion model with the Weather Research and Forecasting (WRF) mesoscale Eulerian model (FLEXPART-WRF) to analyze the expected mid- to late-century changes in the moisture sources and sinks of the North American East Coast (ENA) and the Gulf of Mexico (GM), as well as their most relevant abrupt moisture transport events-atmospheric rivers (ARs) and low-level jets of the Great Plains (GPLLJ) and the Caribbean (CLLJ). Both the ENA and GM are expected to increase in importance as moisture source regions over the century, both overall and in their contributions to the ARs and both LLJs. A notable increase in the intensity of the GPLLJ and CLLJ moisture sources is also observed.

The success of introduced species often relies on flexible traits, including immune system traits. While theories predict non-natives will have weak defences due to decreased parasite pressure, effective parasite surveillance remains crucial, as infection risk is rarely zero and the evolutionary novelty of infection is elevated in non-native areas. This study examines the relationship between parasite surveillance and cytokine responsiveness in native and non-native house sparrows, hypothesizing that non-natives maintain high pathogen surveillance while avoiding costly inflammation.

Determining the optimal antibiotic duration for skin and soft tissue infections.

Curr Opin Infect Dis

January 2025

Department of Medicine, Clínica Rotger Quironsalud, Palma de Mallorca, Spain.

Purpose Of Review: Optimal duration of therapy in SSTIs - a heterogeneous group of infections - remains unknown. The advances in knowledge of antibiotic duration of treatment in selected SSTIs that can impact clinical practice and published in the last 18 months are reviewed.

Recent Findings: Recent evidence indicates that few patients receive guideline concordant empiric antibiotics and appropriate duration in the United States, although this likely can be extrapolated to other countries.

Distal femoral replacement (DFR) with megaprostheses is a salvage revision total knee arthroplasty (rTKA) procedure indicated in cases with massive bone defects in the distal femur. As long as these implants achieve fixation only in the diaphysis, the high aseptic loosening rate reported in some series is probably related to a lack of rotational stability. Two patients with extensive distal femoral bone defects with preservation of the metaphyseal-diaphyseal junction underwent rTKA.

Microtubule associated protein 2 (MAP2) interacts with the regulatory protein 14-3-3ζ in a cAMP-dependent protein kinase (PKA) phosphorylation dependent manner. Using selective phosphorylation, calorimetry, nuclear magnetic resonance, chemical crosslinking, and X-ray crystallography, we characterized interactions of 14-3-3ζ with various binding regions of MAP2c. Although PKA phosphorylation increases the affinity of MAP2c for 14-3-3ζ in the proline rich region and C-terminal domain, unphosphorylated MAP2c also binds the dimeric 14-3-3ζ via its microtubule binding domain and variable central domain.
