Focal Cortical Dysplasia (FCD) & Mesial Temporal Lobe Epilepsy-Hippocampal Sclerosis (MTLE-HS) are two common pathologies of drug-resistant focal epilepsy (DRE). Inappropriate localization of the epileptogenic zones (EZs) in FCD is a significant contributing factor to the unsatisfactory surgical results observed in FCD cases. Currently, no molecular or cellular indicators are available which can aid in identifying the epileptogenic zones (EZs) in FCD.

Objective: Vagus nerve stimulation (VNS) paired with rehabilitation therapy improved motor status compared to rehabilitation alone in the phase III VNS-REHAB stroke trial, but treatment response was variable and not associated with any clinical measures acquired at baseline, such as age or side of paresis. We hypothesized that neuroimaging measures would be associated with treatment-related gains, examining performance of regional injury measures versus global brain health measures in parallel with clinical measures.

Methods: Baseline magnetic resonance imaging (MRI) scans in the VNS-REHAB trial were used to derive regional injury measures (extent of injury to corticospinal tract, the primary regional measure; plus extent of injury to precentral gyrus and postcentral gyrus; lesion volume; and lesion topography) and global brain health measures (degree of white matter hyperintensities, the primary global brain measure; plus volumes of cerebrospinal fluid, cortical gray matter, white matter, each thalamus, and total brain).

Objectives: Although medication abortion drugs technically require a prescription in India, research suggests that they are often available directly from pharmacies. We conducted a mystery client study in the capital city of Delhi to explore the availability, accessibility, and pharmacy dispensing practices of mifepristone/misoprostol in the absence of a prescription.

Study Design: Using two predetermined client profiles-one of an unmarried woman and one of her male partner-we visited community pharmacies in different neighborhoods.

Superconducting diode effects have recently attracted much attention for their potential applications in superconducting logic circuits. Several pathways have been proposed to give rise to non-reciprocal critical currents in various superconductors and Josephson junctions. In this work, we establish the presence of a large Josephson diode effect in a type-II Dirac semimetal 1T-PtTe facilitated by its helical spin-momentum locking and distinguish it from extrinsic geometric effects.

Estimation of the glacier-stored freshwater is important to understand the water security in the Himalayan region. While previous work has studied the western and central Himalayan glaciers, the eastern counterpart received less and more scattered attention. In this study, an attempt is made to quantify the total glacier-stored freshwater in the Brahmaputra basin and later compared with previous global models.

Small molecule probes exist for only ∼2% of human proteins because most lack functional binding pockets or cannot be assayed for high-throughput screening. Selective translation modulation circumvents canonical druggability and assay development constraints by using in vitro transcription-translation (IVTT) as a universal biochemical screening assay. We developed an IVTT activity assay by fusing a GFP reporter to various target gene sequences and screened the target sequences for inhibitors in microfluidic picoliter-scale droplets using a 5,348-member translation inhibitor DNA-encoded library (DEL).

Article Synopsis
  • DNA double-strand breaks (DSBs) are critical to repair for maintaining genome stability, with different chromatin types potentially requiring distinct repair mechanisms.
  • In a study involving Drosophila melanogaster, it was found that DSBs in facultative heterochromatin quickly move outside of specialized structures called polycomb bodies and this movement corresponds with a decrease in a specific histone mark, H3K27me3.
  • The research indicates that the histone demethylase dUtx is essential for this process, as its absence disrupts both the movement of DSBs and the completion of repair via homologous recombination in heterochromatic regions.
