Dietary complementation by wild birds: Considerations for field studiesSpringer Science and Business Media LLC - Tập 19 - Trang 355-368 - 1994
Mary E. Murphy
Free-living birds must satisfy fluctuating nutrient requirements in diverse and varying environments. Ingesting nutritionally complementary foods may be the most effective means by which wild birds match nutrient ingestion and nutrient needs. Dietary complementation may occur fortuitously when foods chosen in response to non-nutritive factors (e.g. competition, predation risk, food colour), or on ...... hiện toàn bộ
Construction, electroporatic transfer and expression of ZpβypGH and ZpβrtGH in zebrafishSpringer Science and Business Media LLC - Tập 23 - Trang 565-576 - 1998
S. G. Sheela, J. D. Chen, S. Mathavan, T. J. Pandian
Recombinant transformation vectors (ZPβypGH and ZpβrtGH) consisting of fish growth hormone cDNA, and a reporter geneβ-galactosidase driven by fish promoter (Zp) were constructed. Freshly fertilized eggs of zebrafish (Brachydanio rerio) were electroporated at optimum conditions (0.07 kV voltage; 25 μF capacitance; 8 ohm resistance and 2 pulses) in the presence of one of these transformation vectors...... hiện toàn bộ
Psychrophiles: A journey of hopeSpringer Science and Business Media LLC - Tập 46 - Trang 1-15 - 2021
Shivani Tendulkar, Aishwarya Hattiholi, Mahesh Chavadar, Suneel Dodamani
Psychrophiles are organisms living in extremely cold conditions within the temperature range of −20°C to + 10°C. These organisms survive in harsh environment by modulating their genetic make-up to thrive in extremely cold conditions. These cold-adaptations are closely associated with changes in the life forms, gene expression, and proteins, enzymes, lipids, etc. This review gives a brief descripti...... hiện toàn bộ
Ventilation rates indicate stress-coping styles in Nile tilapiaSpringer Science and Business Media LLC - Tập 36 - Trang 851-855 - 2011
Rodrigo E Barreto, Gilson L Volpato
Behavioural responses to stress can form distinct profiles in a wide range of animals: proactive and reactive profiles or coping styles. Stress responsiveness can also differentiate between the behavioural profiles. The tendency to regain feed intake following transfer to a novel social-isolation tank (the speed of acclimation) can discriminate between proactive or reactive profiles. Consequently,...... hiện toàn bộ
SARS-CoV-2 genomics: An Indian perspective on sequencing viral variantsSpringer Science and Business Media LLC - Tập 46 - Trang 1-14 - 2021
Surabhi Srivastava, Sofia Banu, Priya Singh, Divya Tej Sowpati, Rakesh K. Mishra
Since its emergence as a pneumonia-like outbreak in the Chinese city of Wuhan in late 2019, the novel coronavirus disease COVID-19 has spread widely to become a global pandemic. The first case of COVID-19 in India was reported on 30 January 2020 and since then it has affected more than ten million people and resulted in around 150,000 deaths in the country. Over time, the viral genome has accumula...... hiện toàn bộ
Microalgae respond differently to nitrogen availability during culturingSpringer Science and Business Media LLC - Tập 40 - Trang 365-374 - 2015
Liliana G Gigova, Natalia J Ivanova
Variations in the exogenous nitrogen level are known to significantly affect the physiological status and metabolism of microalgae. However, responses of red, green and yellow-green algae to nitrogen (N) availability have not been compared yet. Porphyridium cruentum, Scenedesmus incrassatulus and Trachydiscus minutus were cultured in the absence of N in the medium and subsequent resupply of N to t...... hiện toàn bộ
Ascribing functions to the lamin B receptorSpringer Science and Business Media LLC - Tập 24 - Trang 401-408 - 1999
Durgadas P. Kasbekar
This article reviews the research on the inner nuclear membrane protein lamin B receptor (LBR). It focuses on the biochemical and immunological evidence for an LBR; the cloning of chicken, rat and human LBR cDNAs and genomic sequences; the lamin B-, chromatin-, DNA- and NLS-binding properties of the N-terminal domain and its phosphorylation by different kinases; the sterol C-14 reductase activity ...... hiện toàn bộ
Historic migration to South Asia in the last two millennia: A case of Jewish and Parsi populationsSpringer Science and Business Media LLC - Tập 44 - Trang 1-8 - 2019
Ajai K Pathak, Anshika Srivastava, Prajjval Pratap Singh, Debashruti Das, Audditiya Bandopadhyay, Pooja Singh, Gyaneshwer Chaubey
The South Asian populations have a mosaic of ancestries likely due to the interactions of long-term populations of the landmass and those of East and West Eurasia. Apart from prehistoric dispersals, there are some known population movements to India. In this study, we focussed on the migration of Jewish and Parsi populations on temporal and spatial scales. The existence of Jewish and Parsi communi...... hiện toàn bộ
