Evaluation of biochemical composition of hulled and hull-less genotypes of pumpkin seeds grown in subtropical India.

Pumpkin seeds are one of the functional foods with most potential having myriad of uses, and functioning as both edible seeds and oilseeds. Nevertheless, their utilization is restricted to the presence of a thick seed coat (hull) which subjects them to the process of decortication, increasing the farmers' expense as well as limiting their utilization as oilseeds. Therefore, in the present study, characterization of the biochemical composition of the hulled (Punjab Chappan Kadoo-1 abbreviated as PCK-1) and hull-less (PAU Magaz Kadoo-1 abbreviated as PMK-1) genotype of pumpkin seeds was undertaken to assess the nutritional differences and their efficient application; PMK-1 is a new cultivar of pumpkin released by Punjab Agricultural University in 2018. Based on the characterization, the hulled genotype of pumpkin seeds was observed to possess higher content of total soluble proteins (79.62 mg/100 g), total free amino acids (3.48 g/100 g), moisture (6.74%), fibre content (21.1 g/100 g), antioxidant potential (26.15%), polyamines (19.2 mg/100 g), sterols (387.1 mg/100 g), and specific enzymatic activity whereas the hull-less genotype was observed to possess a higher amount of minerals (4.57 g/100 g), tocopherols (15.76 mg/100 g), and oil content (36%) respectively; most of the biochemical parameters do not differ from each other at a greater fold difference except for total free amino acids and fibre, which are nearly four times and three times higher in hulled seeds in comparison to the naked seeds respectively. The two genotypes of seeds do not compete, rather do complement each other in biochemical and nutritional composition.

A randomized comparative study of methylcobalamin, methylcobalamin plus pregabalin and methylcobalamin plus duloxetine in patients of painful diabetic neuropathy.

CONTEXT: Diabetic neuropathy affects 10.5%-32.2% of diabetic population posing clinical burden onto society. AIMS: We aimed to study the efficacy, safety, and tolerability of methylcobalamin, methylcobalamin plus pregabalin, and methylcobalamin plus duloxetine in patients of painful diabetic neuropathy. SETTINGS AND DESIGN: It is a prospective, randomized, open-label, interventional, and parallel-group study done in patients of painful diabetic neuropathy. MATERIALS AND METHODS: A total of 100 patients were recruited and randomized to three study groups A, B, and C on methylcobalamin, methylcobalamin and pregabalin, and methylcobalamin and duloxetine, respectively. Patients were assessed at day 0 and 4, 8, and 12 weeks. The tuning fork test, monofilament test, Thermal Sensitivity testing, and Visual Analog Scale (VAS) were used to analyze vibration, pressure, thermal sensitivity, and pain. STATISTICAL ANALYSIS USED: The results are expressed as mean ± standard deviation. Appropriate statistical methods were used to calculate P value (<0.05 - significant). RESULTS: The increase in number of patients with vibration perception is 11.6%, 37.9%, and 41.4%; pressure sensation is 7.6%, 37.9%, and 37.9%; and thermal sensitivity is 15.4%, 31.1%, and 37.9% in Groups A, B, and C, respectively. The decrease in VAS scores is 0.58 ± 0.14, 3.82 ± 0.05, and 4.17 ± 0.48 in Groups A, B, and C correspondingly. The adverse effects reported in Groups A, B, and C are 0%, 6.9%, and 10.3%, respectively. CONCLUSIONS: Group C is more efficacious when compared to Groups A and B while Group B is safer.

Lead Tolerance and its Accumulation by a Tree Legume: Dalbergia sissoo DC.

Dalbergia sissoo DC, a leguminous tropical timber tree has been investigated against the Pb toxicity; under the Pb-stress, plant's morphology, biochemical parameters and genomic template stability (GTS) screened in vitro. At the optimum Pb tolerance level (150 mg L-1), plant's defense mechanism-superoxide dismutase, catalase, ascorbate peroxidases and proline could trigger to achieve optimum vegetative growth with minimum fluctuations of the GTS. Further, D. sissoo roots could accumulate 2399.8 ± 16 mg kg-1 Pb. Scanning electron microscopy and energy dispersive X-ray spectrometer analysis also revealed the deposition of Pb in root tissues. In a 1 year pot experiment with Pb-contaminated soil, the plants exhibited normal growth, and Pb accumulation significantly enhanced by the amalgamation of citric acid in the soil. Thus, the tree may prove as a potential candidate for Pb phytostabilization.

Impact of regulatory spin of pioglitazone on prescription of antidiabetic drugs among physicians in India: A multicentre questionnaire-based observational study.

Background & objectives: Pioglitazone was suspended for manufacture and sale by the Indian drug regulator in June 2013 due to its association with urinary bladder carcinoma, which was revoked within a short period (July 2013). The present questionnaire-based nationwide study was conducted to assess its impact on prescribing behaviour of physicians in India. Methods: Between December 2013 and March 2014, a validated questionnaire was administered to physicians practicing diabetes across 25 centres in India. Seven hundred and forty questionnaires fulfilling the minimum quality criteria were included in the final analysis. Results: Four hundred and sixteen (56.2%) physicians prescribed pioglitazone. Of these, 281 used it in less than the recommended dose of 15 mg/day. Most physicians (94.3%) were aware of recent regulatory events. However, only 333 (44.8%) changed their prescribing pattern. Seventeen of the 416 (4.1%) physicians who prescribed pioglitazone admitted having come across at least one type 2 diabetes mellitus patient (T2DM) who had urinary bladder carcinoma, and of these 13 said that it was in patients who took pioglitazone for a duration of more than two years. Only 7.8 per cent of physicians (n=58) categorically advocated banning pioglitazone, and the rest opined for its continuation or generating more evidence before decision could be taken regarding its use in T2DM. Interpretation & conclusions: Majority of the physicians though were aware of the regulatory changes with regard to pioglitazone, but their prescribing patterns were not changed for this drug. However, it was being used at lower than the recommended dose. There is a need for generating more evidence through improved pharmacovigilance activities and large-scale population-based prospective studies regarding the safety issues of pioglitazone, so as to make effectual risk-benefit analysis for its continual use in T2DM.

Role of acamprosate in sensorineural tinnitus.

UNLABELLED: Acamprosate with dual mechanism of action as glutamate antagonist and GABA agonist can be a potential target to decrease the severity of sensorineural tinnitus. OBJECTIVE: (1)To study the effectiveness of acamprosate in providing subjective relief and objective improvement in patients having tinnitus of sensorineural origin. (2) To evaluate the adverse events related to the use of acamprosate and also determine the change in quality of life (QOL) parameters. MATERIALS AND METHODS: The study was randomized double-blind, placebo controlled, crossover. Forty adult subjects (>18 years of age), of either sex with tinnitus of sensorineural origin, were administered either acamprosate 333 mg TDS or matched placebo for a period of six weeks followed by a washout period of one week. Drug therapy was switched for another six weeks in consonance with the crossover design. The effect of acamprosate and placebo on subjective relief and objective improvement was evaluated by using modified tinnitus severity, QOL scores and audiometry with tinnitus matching in frequency and loudness. RESULTS: At the end of the study, the drug had shown a statistically significant improvement in reducing the tinnitus score in 92.5% of the patients and placebo with an improvement in 12.5% of the patients. The drug was well tolerated without any serious drug reactions. CONCLUSION: Acamprosate is an effective drug in treating the severity of sensorineural tinnitus without causing much of the side effects.

Cholestatic hepatitis with intravenous ceftriaxone.

Drug-induced liver injury is a major health problem. Its predominant forms include acute hepatitis, cholestasis, and a mixed pattern. Ceftriaxone is a third-generation cephalosporin and is widely used in the postoperative period due to its wider spectrum, longer half-life, and better tissue penetrability. Earlier cases of high aminotransferase levels and hepatitis have also been reported with the use of ceftriaxone. Here we report a case of cholestatic hepatitis with intravenous ceftriaxone.
