The environmental challenge

The human population continues to grow steadily with the shrinking resources being used for agricultural production situates great challenge against Indian agricultural system to attain food and environmental security. To counter these twin challenges in the country there is urgent need of application of modern Hi-tech technologies for enhancing the productivity and sustainability of the rice-wheat system for long term on scientific basis. Precision farming (PF) looks a win-win technology towards improving the capability of agricultural land to produce crops on sustainable basis.

Mindful of the challenges to long-term operation, especially the severe safety and environmental consequences shown through historical nuclear power plant accidents (e.g. Fukoshima, Chernobyl, etc), it is imperative that European research and innovation focuses on demonstrating reliable long-term operation.

We report the isolation of a novel antimicrobial peptide, bass hepcidin, from the gill of hybrid striped bass, white bass (Morone chrysops) · striped bass (M. saxatilis). After the intraperitoneal injection of Micrococcus luteus and Escherichia coli, the peptide was purified from HPLC fractions with antimicrobial activity against Escherichia coli. Sequencing by Edman degradation revealed a 21-residue peptide (GCRFCCNCCPNMSGCGVCCRF) with eight putative cysteines.

Inhaled environmental antigens, i.e. allergens, cause allergic symptoms in millions of patients worldwide. As little is known about the fate of an aller-gen upon inhalation, we addressed this issue for a major dust mite allergen, Der p 2. First, a model for Der p 2-sensitization was established in C57BL⁄6 J mice, in which sensitized mice mounted a Der p 2-specific IgE-response with eosinophilic lung inflammation after allergen challenge in the airways.

When challenged by the dietary soybean cysteine protease inhibitor scN, the cowpea bruchid (Callosobruchus maculatus) adapts to the inhibitory effects by readjusting the transcriptome of its digestive system, including the specific activation of a cathepsin B-like cysteine protease CmCatB.

It remains a challenge to achieve the stable and long-term expression (in human cell lines) of a previously engineered hybrid enzyme [triple-catalytic (Trip-cat) enzyme-2; Ruan KH, Deng H & So SP (2006) Biochemistry45, 14003–14011], which links cyclo-oxygenase isoform-2 (COX-2) to prostacy-clin (PGI2) synthase (PGIS) for the direct conversion of arachidonic acid into PGI2through the enzyme’s Trip-cat functions.

Multidrug resistance is a major challenge in the therapy of cancer and pathogenic fungal infections. More than three decades ago, P-glycoprotein was the first identified multidrug transporter. It has been studied exten-sively at the genetic and biochemical levels ever since. Pdr5, the most abun-dant ATP-binding cassette transporter in Saccharomyces cerevisiae,is highly homologous to azole-resistance-mediating multidrug transporters in fungal pathogens, and a focus of clinical drug resistance research. ...

Pesticides are used to protect crops from insects, weeds and diseases both in dryland and irrigated crop production in Viet Nam. However, reliance on pesticides in crop production system has the potential to cause environmental problems due to contamination of waterways and of produce, adversely affecting the Vietnamese environment and human health.
