Evoking stable and precise tactile sensations via multi-electrode intracortical microstimulation of the somatosensory cortex.

Tactile feedback from brain-controlled bionic hands can be partially restored via intracortical microstimulation (ICMS) of the primary somatosensory cortex. In ICMS, the location of percepts depends on the electrode's location and the percept intensity depends on the stimulation frequency and amplitude. Sensors on a bionic hand can thus be linked to somatotopically appropriate electrodes, and the contact force of each sensor can be used to determine the amplitude of a stimulus.

Efficacy of radiotherapy combined with atezolizumab or docetaxel in patients with previously treated NSCLC.

Radiotherapy showed synergy with immunotherapy, yet the comparative effectiveness of combining immunotherapy (iRT) or chemotherapy (CRT) after platinum therapy failure in advanced non-small cell lung cancer (NSCLC) remains unexplored. We analyzed 163 patients (iRT:  = 120 vs. CRT:  = 43) eligible for combination radiotherapy.

Monitoring alpha-cypermethrin susceptibility of Phlebotomus argentipes, the vector of visceral leishmaniasis in India, using the CDC bottle bioassay.

Background: Visceral leishmaniasis (VL), known as Kala-azar on the Indian subcontinent, is a parasitic disease caused by the flagellated protozoa Leishmania donovani and can be fatal if left untreated. The sand fly Phlebotomus argentipes is the only proven vector of VL in the Southeast Asia region, and VL control in this region has relied on the use of synthetic insecticides for indoor residual spraying (IRS). The use of DDT in VL control programmes has led to the development of resistance to this insecticide in sand flies, resulting in DDT being replaced with the insecticide alpha-cypermethrin.

This study applied the SEM to identify modifiable drivers and solutions of burnout across multiple levels among US Military health providers.

Microgravity's effects on miRNA-mRNA regulatory networks in a mouse model of segmental bone defects.

Rehabilitation from musculoskeletal injuries (MSKI) complicate healing dynamics typically by sustained disuse of bone and muscles. Microgravity naturally allows limb disuse and thus an effective model to understand MSKI. The current study examined epigenetic changes in a segmental bone defect (SBD) mouse model in a prolonged unloading condition after spaceflight (FLT).

A Quantitative Real-Time PCR Assay for Measuring Poxvirus Replication and Cell Binding.

Quantitative real-time PCR (qPCR) is a fast and reliable method to quantify viral genomes as a surrogate to titering on monolayers of cells for measuring virus replication. Whether it be for determining the number of virions released, the total number of genomes produced during infection, or the number of virions bound to a cell, qPCR assays can be adapted to quickly enumerate total viral genomes in a broad range of experiments comparing virus replication under different conditions. In addition, qPCR offers several advantages compared to plaque assays including time, linearity over 9 logs, and scalability from tens-to-hundreds of samples, depending on the qPCR machine.
