Protocol for gene knockdown using siRNA in organotypic cultures of murine gastric muscle.

Understanding the molecular interactions within the neuromuscular apparatus in the stomach is crucial for understanding their role in maintaining interstitial cells, such as the interstitial cells of Cajal (ICC), smooth muscle, and enteric neurons, as well as their contribution to gastric motility in both healthy and diseased states. Disruptions of these systems can lead to various gastric motor disorders and diseases, making it essential to explore their functions in detail. We herein present a protocol for gene knockdown using small interfering RNA (siRNAs) in organotypic culture.

TiCT MXene/MoS hybrid nanocomposites for synergistic smart corrosion protection of epoxy coatings.

MXene nanosheets have recently become a focus of research for corrosion protection due to their two-dimensional, sheet-like structure and distinct physicochemical characteristics. Nevertheless, their susceptibility to restacking and oxidation restricts their practical applications. To address this, the study proposes a custom hybrid structure by growing molybdenum disulfide (MoS) nanoparticles on the TiC MXene nanosheets (MX/MS) to prevent oxidation and restacking.

Identification of a Therapeutic Window for Neurovascular Unit Repair after Experimental Spinal Cord Injury.

Traumatic spinal cord injury (SCI) is a devastating condition for which effective neuroregenerative and neuroreparative strategies are lacking. The post-traumatic disruption of the blood-spinal cord barrier (BSCB) as part of the neurovascular unit (NVU) is one major factor in the complex pathophysiology of SCI, which is associated with edema, inflammation, and cell death in the penumbra regions of the spinal cord adjacent to the lesion epicenter. Thus, the preservation of an intact NVU and vascular integrity to facilitate the regenerative capacity following SCI is a desirable therapeutic target.

Correlation Between TWEAK Serum Level and HTLV-1 Proviral Load in HAM/TSP.

Human T-cell lymphotropic virus type-I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP), the main neurological manifestation of HTLV-I, is a chronic inflammatory disease. Viral-host interaction and host genetics are two important contributors to the development of the HAM/TSP. This study was conducted to measure the serum level of tumor necrosis factor-alpha-like weak inducer of apoptosis (TWEAK) by ELISA method in three groups of participants including 34 HAM/TSP patients (HAM/TSP), 35 asymptomatic HTLV-1 carriers (ACs), and 20 healthy controls (HCs).
