Foster mother Contents and Expressions in Kurunthokai Poems

Sangam literature is rich and subtle. It is questionable whether even the students studying Tamil understand such literary songs. The reason for this is the lack of proper understanding of the changes in the modern language and the literary structure of the Sangam Age. In order to understand these Sangam literatures, it is necessary to analyse these literatures. By analyzing in this way, the appreciation of literature and the study of Sangam literature can be conveyed to the students in a simple manner. In this context, this article examines the contents and outputs of the nurse poems in the Kuruntogi, which is highlighted as "Nalla Kuruntogi" in the Sangam literature

On the occurrence of buckler crab Cryptopodia angulata in the coastal waters of India

464-467The trend of marine non-indigenous species in India has been increasing, with more than half of the species probably being introduced by shipping. A live specimen of buckler crab Cryptopodia angulata was found along the west coast of India at 40 m depth. The recent new records at different Indian coastal locations suggest that the crab is widening its distribution. Shipping is thought to be the possible introduction vector (via ballast) for the spread of C. angulata in the coastal waters of India. Further, the favorable environmental conditions prevalent in the Indian coastal waters may facilitate the establishment and subsequent spread of C. angulata. The invasion of this buckler crab may have negative impact on the native species. Although not present in detectable numbers, C. angulata may pose a major threat to the native species, if it establishes. Information on the establishment and distribution of C. angulata from other locations along the Indian coast would be essential to comprehensively and effectively address the threat

Imaging hypoxia in gliomas

Hypoxia plays a central role in tumour development, angiogenesis, growth and resistance to treatment. Owing to constant developments in medical imaging technology, significant advances have been made towards in vitro and in vivo imaging of hypoxia in a variety of tumours, including gliomas of the central nervous system. The aim of this article is to review the literature on imaging approaches currently available for measuring hypoxia in human gliomas and provide an insight into recent advances and future directions in this field. After a brief overview of hypoxia and its importance in gliomas, several methods of measuring hypoxia will be presented. These range from invasive monitoring by Eppendorf polarographic O(2) microelectrodes, positron electron tomography (PET) tracers based on 2-nitroimidazole compounds [(18)F-labelled fluoro-misonidazole ((18)F-MISO) or 1-(2-[((18))F]fluoro-1-[hydroxymethyl]ethoxy)methyl-2-nitroimidazole (FRP-170)], (64)Cu-ATSM Cu-diacetyl-bis(N4-methylthiosemicarbazone) (Cu-ATSM) or (99m)Tc- and (68)Ga-labelled metronidazole (MN) agents to advanced MRI methods, such as blood oxygenation level dependent (BOLD) MRI, oxygen-enhanced MRI, diffusion-weighted MRI (DWI-MRI), dynamic contrast-enhanced MRI (DCE-MRI) and (1)H-magnetic resonance spectroscopy

Integrated Chromosome 19 Transcriptomic and Proteomic Data Sets Derived from Glioma Cancer Stem-Cell Lines

One subproject within the global Chromosome 19 Consortium is to define chromosome 19 gene and protein expression in glioma-derived cancer stem cells (GSCs). Chromosome 19 is notoriously linked to glioma by 1p/19q codeletions, and clinical tests are established to detect that specific aberration. GSCs are tumor-initiating cells and are hypothesized to provide a repository of cells in tumors that can self-replicate and be refractory to radiation and chemotherapeutic agents developed for the treatment of tumors. In this pilot study, we performed RNA-Seq, label-free quantitative protein measurements in six GSC lines, and targeted transcriptomic analysis using a chromosome 19-specific microarray in an additional six GSC lines. The data have been deposited to the ProteomeXchange with identifier PXD000563. Here we present insights into differences in GSC gene and protein expression, including the identification of proteins listed as having no or low evidence at the protein level in the Human Protein Atlas, as correlated to chromosome 19 and GSC subtype. Furthermore, the upregulation of proteins downstream of adenovirus-associated viral integration site 1 (AAVS1) in GSC11 in response to oncolytic adenovirus treatment was demonstrated. Taken together, our results may indicate new roles for chromosome 19, beyond the 1p/19q codeletion, in the future of personalized medicine for glioma patients
