This study completes data collected for thick targets exposed to carbon and oxygen ions accelerated at 86 MeV/u. The radioactivity induced in carbon and tungsten targets bombarded by argon projectiles at 95 MeV/u has been studied in order to assess the relative contributions of the incoming heavy ion and the mass number of the bombarded nuclei to the consequent radiation hazards related to the production of radioactive ion beams. Induced radioactivity measurements are only rarely made under controlled irradiation conditions, in order to derive from the measured activities the dose rates after beam bombardment and a prediction of radiation protection constraints.

In this study, we developed zwitterionic surface coatings of carboxybetaine by mimicking natural melanogenesis. We synthesized an unnatural tyrosine-conjugated carboxybetaine (Tyr-CB) that undergoes melanin-like oxidation upon treatment with tyrosinase under various aqueous conditions. The thickness of the resulting poly(Tyr-CB) film was tuned by adjusting the pH during the coating process.

Background: Malaria continues to be an important threat to public health and infects millions of children under 5 years of age each year. Although Ethiopia has set targets for at-risk group interventions to eradicate and manage malaria, the illness is still a serious public health problem in areas where it is endemic, especially in the unique lowlands in the Borena zone.
Objective: This study aimed to determine the prevalence of malaria and associated factors among children in Borena's pastoral communities, Oromia Regional State, southern Ethiopia, in 2022.

AUTS2 syndrome is characterized by intellectual disability and microcephaly, and is often associated with autism spectrum disorder, but the underlying mechanisms, particularly concerning microcephaly, remain incompletely understood. Here, we analyze mice mutated for the transcriptional regulator AUTS2, which recapitulate microcephaly. Their brains exhibit reduced division of intermediate progenitor cells (IPCs), leading to fewer neurons and decreased thickness in the upper-layer cortex.

Purpose: We aimed to develop a novel fluorescent surgical gauze dyed with indocyanine green (ICG) to guide surgeons to the target anatomical destination during surgery for real-time navigation and to prevent gauze remnants after surgery.
Methods: Surgical gauze was dyed with an aqueous solution of ICG (5.0 × 10 mol L for Steraze, 1.

Burn injuries in patients with significant pre-existing medical conditions provide unique challenges in both medical management and surgical planning. Spasticity, if left untreated, can be one of the most disabling consequences of a neurologic injury. Treatment is largely dependent on pharmacologic management with anti-spasmodic agents such as baclofen.
