Causes, risk factors, and complications of accidental intra-arterial administration of medications in a children's hospital: a case series.

Background: Accidental intra-arterial administration of a medication can lead to serious iatrogenic harm. Most studies have discussed single cases of accidental intra-arterial administration of a medication, but only a few have described multiple cases occurring in a single, pediatric hospital setting.

Methods: The subjects were pediatric patients with an accidental intra-arterial administration of a medication.

Depletion of perivascular macrophages delays ALS disease progression by ameliorating blood-spinal cord barrier impairment in SOD1 mice.

Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disease in which non-cell-autonomous processes have been proposed as its cause. Non-neuronal cells that constitute the environment around motor neurons are known to mediate the pathogenesis of ALS. Perivascular macrophages (PVM) are immune cells that reside between the blood vessels of the central nervous system and the brain parenchyma; PVM are components of the neurovascular unit and regulate the integrity of the blood-spinal cord barrier (BSCB).

Experimental study platform for electrocatalysis of atomic-level controlled high-entropy alloy surfaces.

High-entropy alloys (HEAs) have attracted considerable attention to improve performance of various electrocatalyst materials. A comprehensive understanding of the relationship between surface atomic-level structures and catalytic properties is essential to boost the development of novel catalysts. In this study, we propose an experimental study platform that enables the vacuum synthesis of atomic-level-controlled single-crystal high-entropy alloy surfaces and evaluates their catalytic properties.

Precalving behavior in dairy cattle with different calving times.

Predicting the calving time in dairy cattle can help in avoiding calving accidents and reducing burdens on animal caretakers. In this study, we analyzed the behavior of pregnant dairy cattle for 7 days prior to calving, to assess the feasibility of predicting the calving time. Eleven Holstein cows were divided into two groups based on their calving times, that is, in the morning (the Morning Parturition Group) or the evening (the Evening Parturition Group).

Analysis of characteristics required for gait evaluation of patients with knee osteoarthritis using a wireless accelerometer.

Background: Knee osteoarthritis (KOA) is associated with reduced quality of life due to knee pain and gait disturbance. However, the evaluation of KOA is mainly based on images and patient-reported outcome measures (PROMs), which are said to be insufficient for functional evaluation. Recently, gait analysis using an accelerometer has been used for functional evaluation of KOA patients.
