Sybil Attack-Resistant Blockchain-Based Proof-of-Location Mechanism with Privacy Protection in VANET.

In this paper, we propose a Proof-of-Location (PoL)-based location verification scheme for mitigating Sybil attacks in vehicular ad hoc networks (VANETs). For this purpose, we employ smart contracts for storing the location information of the vehicles. This smart contract is maintained by Road Side Units (RSUs) and acts as a ground truth for verifying the position information of the neighboring vehicles.

A Case Report of Successful Off-Label Neuromodulation for Concurrent Refractory Sacroiliac Pain and Phantom Limb in a Hip Disarticulation Patient.

Hip disarticulation is a morbid procedure for those whose bony or soft tissues are unable to be salvaged. It involves extensive resection, and the patient featured in this report expressed mechanical pain from their sacroiliac joint (SIJ) as well as phantom limb pain (PLP). Spinal cord stimulation is known to assist with neuropathic pain syndromes, and SIJ fusion is effective in these cases of multifactorial pain.

2,2'- Bipyridine Derivatives Exert Anticancer Effects by Inducing Apoptosis in Hepatocellular Carcinoma (HepG2) Cells.

Purpose: To elucidate the therapeutic potential of 2,2'-bipyridine derivatives [NPS (1-6)] on hepatocellular carcinoma HepG2 cells.

Methods: The effects on cell survival, colony formation, cellular and nuclear morphology, generation of reactive oxygen species (ROS), change in the integrity of mitochondrial membrane potential (MMP), and apoptosis were investigated. Additionally, docking studies were conducted to analyze and elucidate the interactions between the derivatives and AKT and BRAF proteins.

Betel Quid Use and Tuberculosis Transmission: A Neglected Focus Area for Tuberculosis Control in Low- and Middle-Income Countries.

Habitual betel quid consumption and spitting contribute to tuberculosis (TB) transmission due to direct exposure to pathogens, immunosuppression, and social contact. Despite betel quid being classified as a group 1 human carcinogen and a high prevalence of betel quid consumption in patients with TB, there exists a knowledge gap in the relationship between quid use and TB, which presents as a neglected opportunity to address the global burden of TB in low- and middle-income countries. Understanding such a knowledge gap is crucial when taking measures at various levels, including research prioritization, behavior change communication, and legislation to address the availability and access of quid products, coupled with community-based interventional strategies.

Iron Phosphide Nanobundles for Efficient Electrochemical Hydrogen Evolution Reaction in Acidic and Basic Media.

Earth-abundant transition metal phosphide (TMP) nanomaterials have gained significant attention as potential replacements for Pt-based electrocatalysts in green energy applications, such as the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and overall water splitting. In particular, FeP nanostructures exhibit superior electrical conductivity and high stability. Moreover, their diverse composition and unique crystal structures position FeP nanomaterials as emerging candidates for HER electrocatalysts.
