Introduction: The aim of the study is to determine the role of upper motor neuron (UMN) or lower motor neuron (LMN) dysfunction as the primary initiator of distal-proximal and lateral-medial gradients of muscle involvement in amyotrophic lateral sclerosis (ALS).

Methods: Concentric needle electromyography recordings were performed in deltoid, abductor digiti minimi, and first dorsal interosseous (FDI) muscles in patients with ALS and controls during slight voluntary contraction needed to activate two motor units (MU). Five motor unit potential (MUP) pairs were recorded from each muscle.

Laser-Induced Damage of UHMW-PE-Based Layered Ballistic Materials.

The laser-induced damage threshold properties of material structures play a key role in identifying and selecting optimum materials with the respective geometric configurations for laser shielding applications. The laser-induced damage mechanism is predominantly influenced by the absorption, thermal conductivity, and transition temperature characteristics of the materials. Ultrahigh-molecular weight polyethylene (UHMW-PE) ballistic composite sheet structures, traditionally employed for conventional ballistic purposes, merit examination for their laser shielding capabilities, leveraging their established use in conventional shielding applications.

The nanocomposites are prepared from La(NO) in a single step by a green novel method and are characterized by Fourier-transform infrared spectroscopy (FT-IR), ultraviolet-visible spectroscopy (UV-vis), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM).

CDK inhibition results in pharmacologic BRCAness increasing sensitivity to olaparib in BRCA1-WT and olaparib resistant in Triple Negative Breast Cancer.

One in three Triple Negative Breast Cancer (TNBC) is Homologous Recombination Deficient (HRD) and susceptible to respond to PARP inhibitor (PARPi), however, resistance resulting from functional HR restoration is frequent. Thus, pharmacologic approaches that induce HRD are of interest. We investigated the effectiveness of CDK-inhibition to induce HRD and increase PARPi sensitivity of TNBC cell lines and PDX models.
