Response of broad bean (Vicia faba L.) to row spacing and phosphorus under late sown rainfed condition of Manipur.

Abstract: A field experiment was conducted to evaluate the effect of spacing and phosphorus on nodulation, yield and quality of broad bean under late sown rainfed condition of Manipur during the rabi seasons of 2002–03 and 2003–04. On the basis of two years results the highest nodulation, seed yield and crude protein content was associated with the application of 60 kg P2O5/ha which was significantly superior to all the other levels of phosphorus except for the crude protein content which remained on par to 40 kg P2O5/ha. Though significantly higher nodulation and crude protein content of the seed was recorded in wider spacing of 40 × 10cm, however, the highest seed and stover yield were recorded in the closer spacing of 20 × 10 cm.

Enhancing Sugarcane Plant–Ratoon Productivity Through Bud Chip Transplanting Geometry

Abstract: A field experiment was conducted for three consecutive seasons on sugarcane (Saccharum spp. hybrid complex) plant–ratoon system (2013–2016) at Sugarcane Research Institute, Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar, to study the effect of planting distance and row spacing on productivity of sugarcane planted with bud chip raised settlings by furrow-irrigated raised bed method of planting. The results revealed that growth and yield attributes, viz. leaf area index, drymatter accumulation, plant population, plant height, net assimilation rate, cane diameter and millable canes, were significantly influenced due to planting distance and row spacing. The mean higher cane yield (81.7 and 74.6 t/ha) in plant and ratoon crops was obtained at 30 cm planting distance. Though the differences between 30 and 45 cm planting distance were not significant, the higher benefit/cost ratio was obtained at 45 cm planting distance. Among row spacing, planting at 90 cm row spacing showed the highest drymatter accumulation (30.6 and 28.1 t/ha), millable canes (102,000 and 116,300/ha), net returns (Rs. 137,700 and 140,600/ha) and benefit/cost ratio (1.67 and 2.40) in plant and ratoon crops, respectively. Planting of bud chip raised settlings at 90 cm row spacing significantly increased the yield of plant and ratoon canes during all the years of experimentation as well as on mean basis. Sucrose content juice was not affected by planting distance and row spacing. Correlation studies between cane yield and sucrose content with different growth and yield parameters of sugarcane plant and ratoon crops indicated that the yield of sugarcane was significantly and positively correlated with most of the growth and yield parameters.

Length-weight Relationship and Growth Pattern of Common Carp (Cyprinus carpio var. Communis) in Different Pond Environment in Mid Hill Region

Abstract: An experiment on rearing of common carp was carried out in three types of ponds viz. earthen pond, cemented tank and poly tank at field centre, DCFR, Champawat (Uttarakhand) and at selected farmers field of Champawat District to evaluate the growth performance of this fish species. ANCOVA results revealed that there are three distinct seasons which influence on length-weight relationship of common carp culture in these pond systems. The fish follows isometric growth in spring season (March-May); (however it does not follow in the remaining seasons). Further, there is no specific growth pattern of common carp observed in these pond environment. Logistic curve is the best fitted model to the dataset obtained from cemented pond. However, Richards and von-Bertalanffy curves are found appropriate to represent the growth pattern of this fish in earthen and poly tank, respectively. In the long run, higher growth of fish is predicted in poly tank.

Eosinophil: a central player in modulating pathological complexity in asthma

Abstract: Eosinophils are the major inflammatory cells which play a crucial role in the development of allergic and non-allergic asthma phenotypes. Eosinophilic asthma is the most heterogeneous phenotype where activated eosinophils are reported to be significantly associated with asthma severity. Activated eosinophils display an array of cell adhesion molecules that not only act as an activation marker, suitable for assessing severity, but also secrete several tissue factors, cytokines and chemokines which modulate the clinical severity. Eosinophil activations are also strictly associated with activation of other hetero cellular populations like neutrophils, macrophages, mast cells, and platelets which culminate in the onset and progression of abnormal phenotypes such as bronchoconstriction, allergic response, fibrosis instigated by tissue inflammation, epithelial injury, and oxidative stress. During the activated state, eosinophils release several potent toxic signaling molecules such as major basic proteins, eosinophil peroxidase, eosinophil cationic protein (ECP), and lipid mediators, rendering tissue damage and subsequently leading to allergic manifestation. The tissue mediators render a more complex manifestation of a severe phenotype by activating prominent signaling cross-talk. Here, in the current review with the help of search engines of PubMed, Medline, etc, we have tried to shed light and explore some of the potent determinants regulating eosinophil activation leading to asthma phenotype.

Development of novel visual detection methodology for Salmonella in meat using saltatory rolling circle amplification.

Abstract: AIM The aim of this study was to develop a saltatory rolling circle amplification (SRCA) assay for rapid, simple and visual detection of Salmonella in meat. METHODS AND RESULTS Saltatory rolling circle amplification assay was established using simple PCR primers targeting the invA gene of Salmonella enterica. The specificity of the SRCA assay was determined using 28 Salmonella and 15 non-Salmonella strains. The analytical sensitivity of the developed SRCA, conventional and real-time PCR assays were 70 fg, 7 pg and 700 fg S. enterica DNA per tube, respectively. The limit of detection (LoD) of the SRCA assay was 40 CFU per gram of meat without enrichment and 4 CFU per gram after including 6 h brief enrichment step. The detection limits of 40 CFU per gram and 4 CFU per gram of meat were achieved within 165 min and 9 h, respectively (including DNA extraction). To assess the real-world relevance of the SRCA assay, it was used to screen Salmonella from the field pork samples (n = 82). The same samples were also tested with culture (ISO 6579: 2002) method, conventional and real-time PCR assays. Using the developed assay with 6-h enrichment step, it could give accurate results as that of the culture method. CONCLUSIONS The results of this study showed that the SRCA assay is a rapid, simple, sophisticated equipment-free and user-friendly method for accurate detection of Salmonella in meat foods. To our information, this is the first study to deploy SRCA assay for screening foods for Salmonella. SIGNIFICANCE AND IMPACT OF THE STUDY The developed SRCA assay is cost-effective, easy-to-perform and equipment-free; therefore, it has the potential to replace other molecular detection methods for regular screening of Salmonella in foods in field laboratories.
