The toxicity of chlorine dioxide to clownfish and its bactericidal capability to pathogenic strains of vibrio spp.

Global ornamental fish transportation ranging from hours to days can produce multiple stress factors impact fish health and cause mortality. Clownfish, particularly Amphiprion ocellaris, are among the most traded saltwater ornamental fish. Vibrio includes several pathogenic strains that affect aquatic animals.

The effects of proactive approach and integrated medical care on psychological distress in hospitalized patients: A single center experience.

Purpose: Psychological distress is common among patients with acute diseases and is associated with a poorer prognosis. Early detection and intervention are important for high-risk individuals.

Design And Methods: This retrospective study used the five-item Brief Symptom Rating Scale (BSRS-5) to assess psychological distress and evaluate whether proactive intervention may reduce distress levels among hospitalized patients in a single medical center in northern Taiwan.

Comparison of oral malodors before and after nonsurgical periodontal therapy in chronic periodontitis patients.

Background/purpose: Periodontal diseases have been considered as a source of oral malodor or halitosis. Improvement of oral malodor in chronic periodontitis patients has recently been observed after nonsurgical periodontal therapy in combination with tongue cleaning and/or chlorhexidine mouth rinsing. The present study, however, evaluated the impact of nonsurgical periodontal therapy alone on the oral malodor in chronic periodontitis patients by comparing the intraoral concentrations of volatile sulfur compounds (VSCs) before and after nonsurgical therapy.

Application of genetic algorithm on optimization of laser beam shaping.

This study proposes a newly developed optimization method for an aspherical lens system employed in a refractive laser beam shaping system, which performs transformations on laser spots such that they are transformed into flat-tops of any size. In this paper, a genetic algorithm (GA) with multipoint search is proposed as the optimization method, together with macro language in optical simulation software, in order to search for ideal and optimized parameters. In comparison to a traditional two-dimensional (2D) computational method, using the one-dimensional (1D) computation for laser beam shaping can search for the optimal solution approximately twice as fast (after experiments).

Renin activates PI3K-Akt-eNOS signalling through the angiotensin AT₁ and Mas receptors to modulate central blood pressure control in the nucleus tractus solitarii.

Background And Purpose: The renin-angiotensin system (RAS) is critical for the control of blood pressure by the CNS. Recently, direct renin inhibitors were approved as antihypertensive agents. However, the signalling mechanism of renin, which regulates blood pressure in the nucleus tractus solitarii (NTS) remains unclear.

Systemic hypoxia promotes lymphocyte apoptosis induced by oxidative stress during moderate exercise.

Blood undergoes oxidative stress during severe hypoxia or intense exercise. Excessive exposure to oxidative stress induces replicative senescence and apoptosis of lymphocytes. This study determines how various exercises with/without hypoxia affect lymphocyte subset mobilization and oxidative stress-induced lymphocyte apoptosis.
