The nature and extent of genetic diversity were assessed among 23 parents of pigeonpea hybrids employing Mahalanobis D2 statistics. Based on relative magnitude of D2, the genotypes were grouped into five different non-overlapping clusters. Cluster III, having 8 genotypes, emerged with highest number of entries;cluster I, II and V were constituted by four genotypes each while cluster IV, comprising three genotypes, had least number of entries. The highest contribution in manifestation of genetic divergence was exhibited by 100-seed weight followed by pods per plant, days to maturity, harvest index, biological yield per plant, days to 50% flowering and seed yield per plant. The maximum intra-cluster distance was observed for cluster III, followed by cluster IV, cluster I and cluster V. The highest inter-cluster distance was recorded between cluster II and IV followed by cluster I and IV and cluster V and II. The crossing between entries belonging to cluster pairs having large inter-cluster distance and possessing high cluster means for one or other characters to be improved may be recommended for isolating desirable recombinants in the segregating generations in pigeonpea. Considering the mean performance for different characters of genotypes belonging to diverse clusters, the promising genotypes identified were NDA 2, NDA 7-11, IPA 208 and NDA 5-14 of cluster I;NDA 3-3, NDA 98-6, Amar and NDACMS 1-3A of cluster II;NDACMS 1-4A, NDACMS 1-6A and ICP 870 of cluster IV and NDA 96-6, ICP 2155, NDA 8-6 and NDAGC 1010 of cluster V for exploitation as parents in hybridization programme for development of superior pigeonpea hybrid cultivars.

Loose bodies are freely floating fragments of cartilage or bone inside the knee joint space. This is commonly seen in association with degenerative joint disease (DJD), direct or indirect trauma, synovial chondromatosis, osteochondritis dissecans (OCD) and size of the loose body may vary from few millimeters to few centimeters. Patients with loose bodies in knee joint presented to orthopaedists with knee pain, swelling and restricted movement, with intermittent locking or catching of the joint. This is managed surgically most of the times when it becomes symptomatic. The surgical technique most commonly utilized is arthroscopy. Open arthrotomy should be done when the loose bodies are very large/numerous/located in posterior joint space. In review of literature, we found very few cases of giant loose body in knee joint due to DJD reported in last 70 years. We are hereby reporting our case of 60-year-old male with a giant loose body of same size as of patella in the supra-patellar pouch of left knee joint and managed by arthrotomy to remove the giant loose body. Post-operatively patient recovered significantly over the period of 6-week follow-up. In conclusion, giant loose body should be removed through arthrotomy and all such cases should be thoroughly evaluated to diagnose the cause of giant loose body.

A 33 years old female patient presented with posttraumatic pain in the right ibot tor which radiographs of the right foot was advised. No fracture was detected on radiographs and patient was managed conservatively on medications and posterior splint immobilization. We found coincidentally a short fourth metatarsal and an accessory navicular bone in the right foot radiographs. After 3 weeks of immobilization, she underwent mobilization of the right foot, weight bearing and intensive physio- therapy for 6 weeks. After two months of injury she was still complaining of pain on the plantar aspect of right foot which was diagnosed as metatarsalgia and operated on by excision of the neuroma present in the 3rd web space of the right foot. After surgery she was completely relieved of pain and could do activities well related to the right foot.

The aim of this study was to determine nature and extent of variability parameters and their utilization in barley breeding programme. A total of 45 F1s along with their parents and F2 populations were evaluated in a randomized block design with 3 replications during Rabi (winter season) 2014. The various traits measured were days to 50% flowering, days to maturity, plant height, flag leaf area, upper leaf area, tillers-plant, spikes-plant, spike length, grains-spike, spike weight, grain weight-spike, spike harvest index, 1000 grain weight, biological yield-plant, grain yield-plant (g), harvest index, grain size, husk content and protein content. Results showed that significant variation was observed for all the traits studied in the entire gene pool. The degree of genotypic and phenotypic coefficient of variation was high for tillers-plant, spike-plant, grain yield-plant, flag leaf area, harvest index, 1000 grain weight, grain weight-spike, upper leaf area and husk content. High heritability coupled with high genetic advance was recorded for tillers-plant, spikes-plant, grain yield-plant, flag leaf area, harvest index, grain weight-spike, upper leaf area, husk content, grain size and plant height suggesting that these traits are highly heritable and governed by additive gene action. Moderate heritability coupled with high genetic advance was observed for 1000 grain weight, biological yield-plant, spike length, protein content, grains-spike and spike weight;however, days to 50% flowering and days to maturity had moderate heritability coupled with low genetic advance suggesting preponderance on non-additive gene action in the inheritance of these traits. It could be concluded that the traits of tillers-plant, spikes-plant, grain yield-plant, flag leaf area, harvest index, grain weight-spike, upper leaf area, husk content, grain size and plant height were identified as most decisive factor intended towards developing high yielding barley cultivars.

AIM: To assess the correlation between blood pressure levels and fasting plasma glucose levels among young adults attending Chatrapati Shahuji Maharaj University, Kanpur, ***: The present study was cross-sectional in nature, conducted among students in the Institute of Paramedical Sciences, Chatrapati Shahuji Maharaj University, Kanpur. Study subjects included 185 young adults. Among them, 94 were males and 91 were females, in the age group 17 to 19 ***: Mean age among males was 18.5 ± 1.5 years and among females was 17.9 ± 1.8 years. Of the total 185 study subjects, 61(32.9%) were classified as pre-diabetic and 20(10.8%) as pre-hypertensive. Mean waist circumference, systolic blood pressure and serum high density lipoprotein did not vary significantly between normoglycemic and pre-diabetic subjects. However, the mean diastolic blood pressure of pre-diabetics(82 ± 5 mm Hg) was significantly higher than normoglycemics(79 ± 6 mm Hg). Mean serum cholesterol, serum triglycerides, serum low density lipoprotein(LDL) and serum very low density lipoprotein was also higher among pre-diabetic subjects in comparison to normoglycemic subjects and the difference was statistically significant. Upon multiple linear regression analysis, it was observed that body mass index(BMI)(β = 0.149), diastolic blood pressure(β = 0.375) and serum LDL(β = 0.483) were significantly associated with fasting plasma glucose. Multiple linear regression with diastolic blood pressure as the outcome variable showed that BMI(β = 0.219), fasting blood glucose(β = 0.247) and systolic blood pressure(β = 0.510) were significantly ***: A significant prevalence of pre-diabetes and pre-hypertension in young adults is a matter of concern therefore all young adults need to be targeted for screening of diabetes and hypertension and lifestyle modification.

Renewable biomass-derived fuels are essential to meet the blend mandates and the sustainability goals. In our first-to-date study, we investigated individual and synergistic consortia of fungal cultures comprising Pycnoporous sanguineus (PS) in combination with Aspergillus oryzae (AO) and Trichoderma harzianum (TH) for production of cellulolytic enzymes using groundnut shell under solid state and submerged liquid fermentation conditions. The innovative consortia closely align with the microbial ecosystems found in nature;consequently, we anticipate a potent and effective cellulolytic enzyme system, which maximises the breakdown of biomass polymers to sugars. Under ternary combination of cultures, cellulase production was highest at 123.0 ± 1 FPU/gds;β-glucosidase production at 875.6 ± 26.4 IU/g dry substrate (gds);and CMCase at 474.95 ± 45.5 IU/gds. β-glucosidase production was highest on the 2nd day at 987.03 ± 64.2 IU/gds while CMCase peaked at 514.97 ± 21.4 IU/gds on 2nd day for PS, maximum cellulase enzyme production was observed on the 6th day at 192.2 ± 0.96 FPU/gds (AO + PS). Present work showed that synergistic combination of fungal cultures for releasing balanced enzyme activities that can efficiently saccharify biomass, such as groundnut shell to sugars, which can subsequently be fermented to various bioproducts and biomaterial monomers. Elaborate characterization studies of enzyme treated groundnut shell revealed prominent physicochemical changes in the hydrolysate, which indicates the changes in biomass are due to the enzymatic action and the growth effects of the consortia;thereby, leading to promising applications for the microbial fortified biomass.
