Phytohormonal regulation determines the organization pattern of shoot aerenchyma in greater duckweed (Spirodela polyrhiza).

Airspace or aerenchyma is crucial for plant development and acclimation to stresses such as hypoxia, drought, and nutritional deficiency. Although ethylene-mediated signaling cascades are known to regulate aerenchyma formation in stems and roots under hypoxic conditions, the precise mechanisms remain unclear. Moreover, the cellular dynamics underlying airspace formation in shoots are poorly understood.

Sterol Biosynthesis Contributes to Brefeldin-A-Induced Endoplasmic Reticulum Stress Resistance in Chlamydomonas reinhardtii.

The endoplasmic reticulum (ER) stress response is an evolutionarily conserved mechanism in most eukaryotes. In this response, sterols in the phospholipid bilayer play a crucial role in controlling membrane fluidity and homeostasis. Despite the significance of both the ER stress response and sterols in maintaining ER homeostasis, their relationship remains poorly explored.

Effects of left thigh blood flow restriction exercise on muscle strength and golf performance in amateur golfers.

This study aimed to investigate the effect of lower-extremity strengthening exercise (LSE) with and without blood flow restriction (BFR) on the left thigh on golf performance. Eighteen amateur golfers with more than 1 year of golf experience participated in the study and were randomly divided into two groups: LSE+BFR group (LSE with BFR on the left thigh, n=9) and LSE group (LSE without BFR, n=9). The LSEs consisted of squats, lunges, and standing leg curls.

One-year Cohort Follow-up on the Diagnosis and Posttraumatic Symptoms in Child Sexual Assault Victims in Korea.

Objective: The victims and their families of child sexual abuse (CSA) may confront persistent psychological sequela. We aimed to investigate the psychological symptoms, diagnosis, and family functions in children and adolescents with CSA.

Methods: We assessed the symptom scales at 6-month intervals, and conducted diagnostic re-assessments at 1-year intervals.

Arabidopsis ABCG27 plays an essential role in flower and leaf development by modulating abscisic acid content.

Abscisic acid (ABA) is a phytohormone that mediates stress responses and regulates plant development. Several ATP-binding cassette (ABC) transporters in the G subfamily of ABC (ABCG) proteins have been reported to transport ABA. We investigated whether there are any other ABCG proteins that mediate plant developmental processes regulated by ABA in Arabidopsis (Arabidopsis thaliana).

Dual-afferent sensory input training for voluntary movement after stroke: A pilot randomized controlled study.

Background: Stimulation through afferent sensory input is necessary to improve voluntary functional movement in stroke patients.

Objectives: Dual-afferent sensory input, which combines electromyography-triggered functional electric stimulation (ETFES) and action observation, was investigated to determine its effects on voluntary movements in stroke patients.

Methods: This study was conducted on 18 patients with left hemiplegia diagnosed between 6 and 24 months prior.

Plant ABC Transporters Enable Many Unique Aspects of a Terrestrial Plant's Lifestyle.

Terrestrial plants have two to four times more ATP-binding cassette (ABC) transporter genes than other organisms, including their ancestral microalgae. Recent studies found that plants harboring mutations in these transporters exhibit dramatic phenotypes, many of which are related to developmental processes and functions necessary for life on dry land. These results suggest that ABC transporters multiplied during evolution and assumed novel functions that allowed plants to adapt to terrestrial environmental conditions.

Neurofeedback training improves the dual-task performance ability in stroke patients.

Owing to the reduced capacity for information processing following a stroke, patients commonly present with difficulties in performing activities of daily living that combine two or more tasks. To address this problem, in the present study, we investigated the effects of neurofeedback training on the abilities of stroke patients to perform dual motor tasks. We randomly assigned 20 patients who had sustained a stroke within the preceding 6 months to either a pseudo-neurofeedback (n = 10) or neurofeedback (n = 10) group.

Analgesic effect of transcranial direct current stimulation on central post-stroke pain.

Pain that occurs after a stroke lowers the quality of life. Such post-stroke pain is caused in part by the brain lesion itself, called central post-stroke pain. We investigated the analgesic effects of transcranial direct current stimulation (tDCS) in stroke patients through quantitative sensory testing.

Effect of lithospermi radix on contact dermatitis induced by dinitrofluorobenzene in mice.

Objective: The root of Lithospermum erythrorhizon Sieb. et Zucc. (Lithospermi Radix, LR) is a kind of heat clearing and blood cooling medicinal herbs.
