The Rapid Office Strain Assessment (ROSA) was developed to assess musculoskeletal disorder (MSD) risk factors for computer workstations. This study examined the validity and reliability of remotely conducted, photo-based assessments using ROSA. Twenty-three office workstations were assessed on-site by an ergonomist, and 5 photos were obtained. Photo-based assessments were conducted by three erg...

Suspension cultures were incubated in the presence and absence of gibberellic acid (GA(3)) in an attempt to define a new experimental system for study of the molecular action of gibberellins upon growth. Unlike many suspension cultures, an auxin-independent green clone from spinach (Spinacia oleracea L.) and an auxin-dependent line of "Paul's Scarlet" rose (Rosa sp.) were promoted in expansion ...

Natural dyes have become a viable alternative to expensive organic sensitizers because of their low cost of production, abundance in supply, and eco-friendliness. We evaluated 35 native plants containing anthocyanin pigments as potential sensitizers for DSSCs. Melastoma malabathricum (fruit pulp), Hibiscus rosa-sinensis (flower), and Codiaeum variegatum (leaves) showed the highest absorption pe...

Systemic mastocytosis (SM) is a clonal bone marrow disorder, where therapeutical options are limited. Over 90% of the patients carry the D816V point mutation in the KIT receptor that renders this receptor constitutively active. We assessed the sensitivity of primary mast cells (MC) and mast cell lines HMC1.2 (D816V mutated), ROSA (KIT WT) and ROSA (KIT D816V) cells to histone deacetylase inhibi...

Aortic smooth muscle cells (SMCs) have been proposed to derive from lateral plate mesoderm. It has further been suggested that induction of SMC differentiation is confined to the ventral side of the aorta, and that SMCs later migrate to the dorsal side. In this study, we investigate the origin of SMCs in the descending aorta using recombination-based lineage tracing in mice. Hoxb6-cre transgeni...

Learning Content Management System (LCMS) supports e-learning applications with storage and efficient access for e-Learning Objects (LOs). In order to foster LCMS adoption by the e-learning community, an important issue is to bring course modelling to the realm of the LCMS. In this paper, we describe the Repository of Objects with Semantic Access (ROSA) project. ROSA is a LCMS that provides use...

زمینه و هدف: در حال حاضر شواهد فزاینده‌ای وجود دارد که نشان می‌دهد مسیرهای پیش‌التهابی توسط سلول‌های T (که IL-17 IL-22 را ترشح می‌کنند)، تعدیل می‌شوند، نقش مهمی کنترل سوخت‌وسازی دارند. هدف از پژوهش بررسی اثر تمرین هوازی همراه با مصرف عصارة آبی سیر بر بیان IL-17، مقاومت‌ به ‌انسولین موش‌های صحرایی دیابتی استرپتوزوتوسین است.مواد روش‌ها: این تحقیق تجربی،40 سر موش نر (سن 5 هفته وزن 24/15 ± 12/162 گ...

This research was done to test the effect of Rosa damascena essential oil on withdrawal signs of naloxone-precipitated morphine in male mice. Morphine dependence was induced by injection (IP) three times daily at doses of 50, 50 and 75 mg/kg, respectively, for 3 days. On day 4, after the last administration of morphine, Rosa damascena essential oil was administered at different concentrations (...

Forty-four taxa of three sections (Cinnamomeae (=Rosa) 26, Chinenses 8 and Gallicanae 10) and eight modern garden roses in the genus Rosa were surveyed for their floral anthocyanins. Eleven anthocyanins: 3-glucosides and 3,5-diglucosides of cyanidin (Cy), pelargonidin (Pg) and peonidin (Pn), 3-rutinosides and 3-rho-coumaroylglucoside-5-glucosides of Cy and Pn, and Cy 3-sophoroside, were isolate...
