Comparative analysis of development and survivorship of two geographically divergent populations of the Natal fruit fly Ceratitis rosa Karsch designated as Ceratitis rosa R1 and Ceratitis rosa R2 from Kenya and South Africa were studied at seven constant temperatures (10, 15, 20, 25, 30, 33, 35 °C). Temperature range for development and survival of both populations was 15-35 °C. The development...

Here we have characterized the putative Zn(II)2Cys6 transcription factor RosA from the filamentous fungus Aspergillus nidulans. The rosA gene encodes a protein of 713 aa, which shares 38% sequence similarity to Pro1 from Sordaria macrospora. In contrast to Pro1, which promotes the transition from protoperithecia to perithecia, RosA is a negative regulator of sexual development in A. nidulans. T...

In this work we present the first version of ROSA Analyser, a tool designed to get closer to a fully automatic process of analysing the behaviour of a system specified as a process of the Markovian Process Algebra ROSA. In this first development stage, ROSA Analyser is able to generate the Labelled Transition System, according to ROSA Operational Semantics. ROSA Analyser performance starts with...

Rosa: Tape 1, Side B The recording begins in a delicatessen. Rosa is with her mother and twin brother. Over the noise of cars passing the shop, Rosa’s mother can be heard ordering some Cabanas while Rosa sings a song by her favourite pop group 5ive. As they leave the shop, Rosa says goodbye to the shopkeeper who had given the twins a free meat pie each. Their mother asks them to wait until they...

Roses (Rosa indica) belong to one of the most crucial groups of plants in the floriculture industry. Rosa species have special fragrances of interest to the perfume and pharmaceutical industries. The genetic diversity of plants based on morphological characteristics is difficult to measure under natural conditions due to the influence of environmental factors, which is why a reliable fingerprin...

Rosmarinic acid (RosA) is a hydroxylated compound frequently found in herbal plants and is mostly responsible for anti-inflammatory and antioxidative activity. Previously, we observed that RosA inhibited T-cell antigen receptor (TCR)- induced interleukin 2 (IL-2) expression and subsequent T-cell proliferation in vitro. In this study, we investigated in detail inhibitory mechanism of RosA on TCR...

OBJECTIVE Immediate rapid on-site assessment (ROSA) of fine needle aspiration cytology (FNAC) specimens by biomedical scientists (BMS), the UK equivalent of cytotechnologists, or by pathologists may improve specimen quality and cellular adequacy rates for lymph node, head and neck and thyroid FNAC. The aim of this study was to evaluate the effect of introducing ROSA by BMS in an outpatient clin...

Transgenic overexpression of the Notch1 intracellular domain inhibits osteoblast differentiation and causes osteopenia, and inactivation of Notch1 and Notch2 increases bone volume transiently and induces osteoblastic differentiation. However, the biology of Notch is cell-context-dependent, and consequences of Notch activation in cells of the osteoblastic lineage at various stages of differentia...

The Rapid Office Strain Assessment (ROSA) was designed to quickly quantify risks associated with computer work and to establish an action level for change based on reports of worker discomfort. Computer use risk factors were identified in previous research and standards on office design for the chair, monitor, telephone, keyboard and mouse. The risk factors were diagrammed and coded as increasi...

Apoptosis is one way of controlling immune responses, and a variety of immunosuppressive drugs suppress harmful immune responses by inducing apoptosis of lymphocytes. In this study we observed that rosmarinic acid, a secondary metabolite of herbal plants, induced apoptosis in an p56(lck) (Lck)-dependent manner; Lck(+) Jurkat T cells undergo apoptosis in response to rosmarinic acid (RosA) treatm...
