Evaluation of genotype by environment interaction and adaptability in lowland irrigated rice hybrids for grain yield under high temperature.

Recent predictions on climate change indicate that high temperature episodes are expected to impact rice production and productivity worldwide. The present investigation was undertaken to assess the yield stability of 72 rice hybrids and their parental lines across three temperature regimes over two consecutive dry seasons using the additive main effect and multiplicative interaction (AMMI), genotype and genotype × environment interaction (GGE) stability model analysis. The combined ANOVA revealed that genotype × environment interaction (GEI) were significant due to the linear component for most of the traits studied.

Retinal detachment following focal laser to ruptured retinal artery macro aneurysm.

A 53-year-old lady presented with inferior retinal detachment (RD) following focal laser for retinal artery macroaneurysm (RAM). She underwent focal laser with intravitreal gas injection elsewhere; however, no retinal break was localized on the examination. The patient was taken up for vitreoretinal surgery.

Macromolecular properties and partial amino acid sequence of a Kunitz-type protease inhibitor from okra ( seeds.

A Kunitz-type protease inhibitor (OPI, okra protease inhibitor) has been purified from okra (Abelmoschus esculentus) seeds by a combination of ammonium sulfate precipitation, anion-exchange chromatography and reverse-phase high-performance liquid chromatography. The protein shows an apparent mass of 21 kDa on sodium dodecyl sulfate-polyacrylamide gel electrophoresis under reducing condition. OPI exhibits inhibitory activity against trypsin.

Proteins as the Molecular Markers of Male Fertility.

Proteins play a key role in many functions such as metabolic activity, differentiation, as cargos, and cell fate regulators. It is necessary to know about the proteins involved in male fertility to develop remedies for the treatment of male infertility. However, the role of the proteins is not limited to particular aspect in the biological systems.

Muscle transcriptome resource for growth, lipid metabolism and immune system in Hilsa shad, Tenualosa ilisha.

The information on the genes involved in muscle growth, lipid metabolism and immune systems would help to understand the mechanisms during the spawning migration in Hilsa shad, which in turn would be useful in its future domestication process. The primary objective of this study was to generate the transcriptome profile of its muscle through RNA seq. The total RNA was isolated and library was prepared from muscle tissue of Tenualosa ilisha, which was collected from Padma River at Farakka, India.

Sub-epithelial connective tissue graft for root coverage in nonsmokers and smokers: A pilot comparative clinical study.

Background: Gingival recession is a common condition and is more prevalent in smokers. It is widely believed that root coverage procedures in smokers result in less desirable outcome compared to nonsmokers', and there are few controlled studies in literature to support this finding. Therefore, the purpose of this study was to evaluate and compare the outcome of root coverage with sub-epithelial connective tissue graft (SCTG) in nonsmokers and smokers.

Evaluation of Ica Gene in Comparison with Phenotypic Methods for Detection of Biofilm Production by Coagulase Negative Staphylococci in a Tertiary Care Hospital.

Background: Biofilm producing bacteria are responsible for several chronic infections and are difficult to treat as they show much greater resistance to antibiotics. The major virulence factor determining the pathogenicity of CoNS has now well defined and found to be biofilm production.

Objective: The study was conducted to isolate and characterize Coagulase Negative Staphylococci (CoNS) and their ability to form biofilms was evaluated by phenotypic and genotypic methods.

Post-capture immune gene expression studies in the deep-sea hydrothermal vent mussel Bathymodiolus azoricus acclimatized to atmospheric pressure.

Deep-sea hydrothermal vents are extreme habitats that are distributed worldwide in association with volcanic and tectonic events, resulting thus in the establishment of particular environmental conditions, in which high pressure, steep temperature gradients, and potentially toxic concentrations of sulfur, methane and heavy metals constitute driving factors for the foundation of chemosynthetic-based ecosystems. Of all the different macroorganisms found at deep-sea hydrothermal vents, the mussel Bathymodiolus azoricus is the most abundant species inhabiting the vent ecosystems from the Mid-Atlantic Ridge (MAR). In the present study, the effect of long term acclimatization at atmospheric pressure on host-symbiotic associations were studied in light of the ensuing physiological adaptations from which the immune and endosymbiont gene expressions were concomitantly quantified by means of real-time PCR.
