Concrete-filled tubular (CFT) columns have been widely used as structural members because CFT columns synergize the advantages of steel and concrete resulting in high strength, high ductility, and large energy dissipation capacity. Numerous studies have been performed to understand the behavior of CFT columns. However, the behavior of CFT columns remains uncertain due to their inelastic behavior and uncertain confinement effects, especially when failure occurs.

Consequently, evaluation of the coronary venous system and understanding cardiac vein anatomy is crucial.
Purpose: To determine the optimal image set in a comparison of noise-optimized linearly blended images (F_0.
A variety of natural compounds have been used to reduce the oxidative stress associated with Alzheimer's disease, and many of these defend cells from oxidative stress-induced neuronal toxicity. In this study, the protective effect of radish () extract was investigated in mice and PC12 cells. behavioral tests were completed to examine the protective effects of the extract on amyloid beta (A)-peptide-induced learning and memory impairment in a mouse model.

However, detailed information of the colony formation has not yet been sufficiently reported in male germ cell culture. To elucidate the formation of germ cell-derived colony (GDC), glial cell-derived neurotrophic factor receptor alpha-1 (GFRα-1)-positive pig germ cells were isolated using an immunomagnetic cell isolation method and labeled with red- or green-fluorescent dye.

Although germ cell-derived colonies (GDCs) have been successfully cultured from neonatal pig testicular cells under 31°C conditions, the short period of in vitro maintenance (<2 months) limited their application to further investigations. To develop a culture method that allows for in vitro maintenance of GDCs for long periods, we subcultured the GDCs with freshly prepared somatic cells from neonatal pig testes as feeder cells.

Recent studies showed that peroxisome proliferator-activated receptor (PPAR) δ plays a critical role in wound healing.
Objective: To determine whether the nuclear receptor PPARδ can modulate the differentiation of human dermal fibroblasts (HDFs) into myofibroblasts.
To evaluate the hepatotoxicity and nephrotoxicity of Galla Rhois (GR) toward the liver and kidney of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed after oral administration of 250, 500 and 1,000 mg/kg body weight/day of gallotannin-enriched extract of GR (GEGR) for 14 days. GEGR contained 68.7±2.

For this, we have constructed an absolute barrier-sustained gnotobiotic facility. Pregnant sows of gnotobiotic miniature swine, were procured and germfree piglets were obtained by hysterectomy.

Concurrently, an automated enzyme-linked immunosorbent assay method for detecting Campylobacter spp. (VIDAS Campylobacter) was evaluated by comparing it with the culture methods.

Methods: A total of 75 college students (men:women = 53:22), aged 19-24 years, were enrolled in this study. Each subject was asked to complete the profile of mood states and to produce a sustained vowel sound (/a/) for 3 s to calculate acoustic parameters.
An integral imaging system enabling extended depth of field was proposed and demonstrated based on a birefringence lens array (BLA) whose focal length was switched via the light polarization. The lens array system was constructed by combining two different liquid crystal(LC) embedded lens arrays, BLA I and II, which were fabricated by injecting a ZLI-4119 LC and an E-7 LC in between a lens array substrate and an ITO (indium-tin-oxide) glass plate respectively. The BLA I played a role as a convex lens only for the polarization parallel to the ordinary axis of the corresponding LC, but it serves as a plain medium for that along its extraordinary one since the refractive indexes of the lens and the LC are almost identical.
