Hearing loss in children constitutes a considerable handicap because it is an invisible disability and compromises optimal development and personal achievement of a child. The period from birth to 5 years of life is critical for the development of speech and language;therefore, there is need for early identification and assessment of hearing loss and early rehabilitation in infants and children. Cochlear implants are the treatment of choice for patients with severe to profound sensorineural hearing loss. The goal of the present study was to investigate the different hearing impairment etiologies of patients implanted in cochlear implant program. The hospital based interventional study was conducted in the Department of Otorhinolaryngology, SMS Medical College, Jaipur from July 2011 to Dec. 2013. Present study included 60 prelingually deafened patients who attended ENT OPD and underwent cochlear implant. The most common cause of deafness in our study was acquired (56.66%), which predominantly included perinatal risk factors (64.70%), followed by prenatal risk factors (41.17%). The second common cause was hereditary (26.66%), followed by unknown (16.66%). Infection and ototoxic drug history were the most common risk factors in prenatal and postnatal group. The most common perinatal cause was low birth weight and prematurity.

We describe the cases of three patients, under the care of the rheumatology service, who presented with osteonecrosis of the jaw whist on oral bisphosphonate therapy. The first case is of a 74-year-old woman with a 12 year history of sero-negative inflammatory arthritis, having been on oral steroids for 11 years, Methotrexate for the preceding 6 years, and oral bisphosphonates for 9 years. Clinical and radiographic examination revealed extensive jaw necrosis. The second patient was a 72-year-old woman with temporal arteritis, on long term oral steroids, and oral bisphosphonates presenting with jaw osteonecrosis. The third case is of an 81-year-old lady with a diagnosis of Polymyalgia Rheumatica on reducing dose of prednisolone along with calcium and vitamin D3 and oral bisphosphonate therapy as part of steroid induced prophylaxis guidelines. On reviewing the literature regarding bisphosphonate-associated osteonecrosis of the jaw, there is indeed recognition of this occurring with oral bisphosphonates. However, this is far less common than with intravenous preparations. Reports to the UK MHRA regarding adverse reactions have shown 53 cases of osteonecrosis of the jaw associated with oral bisphosphonates, but this is thought to represent under-reporting. We suggest consideration of patient counselling and consent, and preventive dental work prior to initiation of oral bisphosphonate therapy.

Limited information is available for soybean root traits and their plasticity under drought stress. To date, no studies have focused on examining diverse soybean germ- plasm for regulation of shoot and root response under water limited conditions across varying soil types. In this study, 17 genetically diverse soybean germplasm lines were selected to study root response to water limited conditions in clay （trial 1） and sandy soil （trial 2） in two target environments. Physiological data on shoot traits was measured at multiple crop stages ranging from early vegetative to pod filling. The phenotypic root traits, and biomass accumulation data are collected at pod filling stage. In trial 1, the number of lateral roots and forks were positively correlated with plot yield under water limitation and in trial 2, lateral root thickness was positively correlated with the hill plot yield. Plant Introduction （PI） 578477A and 088444 were found to have higher later root number and forks in clay soil with higher yield under water limitation, in sandy soil, P1458o2o was found to have a thicker lateral root system and higher yield under water limitation. The genotypes identified in this study could be used to enhance drought tolerance of elite soybean cultivars through improved root traits specific to target environments.

Previous research suggests that Gossypium has undergone a 5-to 6-fold multiplication following its divergence from Theobroma. However, the number of events, or where they occurred in the Malvaceae phylogeny remains unknown. We analyzed transcriptomic and genomic data from representatives of eight of the nine Malvaceae subfamilies. Phylogenetic analysis of nuclear data placed Dombeya(Dombeyoideae) as sister to the rest of Malvadendrina clade, but the plastid DNA tree strongly supported Durio(Helicteroideae) in this position. Intraspecific Ks plots indicated that all sampled taxa, except Theobroma(Byttnerioideae), Corchorus(Grewioideae), and Dombeya(Dombeyoideae), have experienced whole genome multiplications(WGMs). Quartet analysis suggested WGMs were shared by Malvoideae-Bombacoideae and Sterculioideae-Tilioideae, but did not resolve whether these are shared with each other or Helicteroideae(Durio).Gene tree reconciliation and Bayesian concordance analysis suggested a complex history. Alternative hypotheses are suggested, each involving two independent autotetraploid and one allopolyploid event. They differ in that one entails an allopolyploid origin for the Durio lineage,whereas the other invokes an allopolyploid origin for Malvoideae-Bombacoideae. We highlight the need for more genomic information in the Malvaceae and improved methods to resolve complex evolutionary histories that may include allopolyploidy, incomplete lineage sorting, and variable rates of gene and genome evolution.

Objectives: The basic mechanisms of cervical incompetence remain unknown although preliminary histological, biochemical and DNA studies suggest connective tissue pathology may be a contributing factor. Certain connective tissue disorders are known to be associated with obstetric complications. Utilising a standardised established scoring system for connective tissue laxity, this study aimed to test the relationship between clinical evidence of connective tissue laxity and cervical incompetence. Methods: This case-control study involved pregnant and non-pregnant women with a history of mid-trimester pregnancy loss in the absence of major bleeding, infection and uterine abnormalities and a control group of women with uncomplicated obstetric histories. Relevant medical details were obtained. Connective tissue laxity was assessed utilizing the Beighton scoring system. Potential confounding factors, including age, pregnancy and gestation were explored. Results: The frequency of connective tissue laxity between the cases [n = 29] was not statistically different from the controls [n = 58] [p = 0.391] suggesting a lack of association between cervical incompetence and clinical evidence of connective tissue laxity. Conclusion: Although no clear evidence of connective tissue laxity was demonstrated, it is possible that cervical incompetence is associated with abnormal connective tissue. But this abnormality is different from the defect that underlies joint hypermobility and skin elasticity.

Type 2 diabetes mellitus and its complications are associated with oxidative stress and the depletion of antioxidant defenses. The influence of acetylsalicylic acid on reversing the decrease in antioxidants, insulin resistance, glucose homeostasis, and inflammatory cascade can help prevent diabetes complications. Purpose: The aim of the study was to evaluate the effect of acetylsalicylic acid on the antioxidant enzymatic system in patients with diabetes. Methods: A randomized, double-blind, placebo-controlled clinical trial was carried out in 21 patients of both sexes with Type 2 diabetes for less than five years at the time of diagnosis, without pharmacological treatment, and randomly selected. Acetylsalicylic acid (300 mg) was administered orally for three months to the study group (n = 11) compared to the placebo control group (n = 10). Before and after the intervention, anthropometric and metabolic measurements were taken, fasting plasma glucose, glycated hemoglobin A1c, lipid profile panel, glutathione peroxidase, superoxide dismutase, catalase, and antioxidant capacity/activity were determined;values are presented as mean ± standard deviation. Intra- and intergroup differences were tested by Wilcoxon signed rank and Mann-Whitney U test, respectively;p-value ≤ 0.05 was considered statistically significant. Results: The acetylsalicylic acid group showed a decrease in weight (85.6 ± 19.3 vs. 84.1 ± 19.0 kg p = 0.01), cholesterol (205.9 ± 16.6 vs. 186.0 ± 23.2 mg/dL p = 0.02), and glycated hemoglobin A1c (7.8% ± 0.9% vs. 7.0% ± 0.7% p = 0.02). The placebo group exhibited reduction in weight (76.1 ± 14.9 vs. 74.9 ± 15.0 kg p = 0.04), glycated hemoglobin A1c (6.9% ± 0.6% vs. 6.2% ± 0.4% p = 0.004), and total antioxidant capacity (4.1 ± 0.5 vs. 4.8 ± 0.3 mmol/L p = 0.002). Conclusion: The administration of acetylsalicylic acid did not modify the antioxidant enzyme system.

In classical convex optimization theory, the Karush-Kuhn-Tucker (KKT) optimality conditions are necessary and sufficient for optimality if the objective as well as the constraint functions involved is convex. Recently, Lassere [1] considered a scalar programming problem and showed that if the convexity of the constraint functions is replaced by the convexity of the feasible set, this crucial feature of convex programming can still be preserved. In this paper, we generalize his results by making them applicable to vector optimization problems (VOP) over cones. We consider the minimization of a cone-convex function over a convex feasible set described by cone constraints that are not necessarily cone-convex. We show that if a Slater-type cone constraint qualification holds, then every weak minimizer of (VOP) is a KKT point and conversely every KKT point is a weak minimizer. Further a Mond-Weir type dual is formulated in the modified situation and various duality results are established.
