    Objective: This evaluation study aims to initiate a relatively sensitive RP-HPLC quantifiable technique for evaluating pregabalin (PRBN) and etoricoxib (ETRB) combination in tablet and bulk kinds. Methods: PRBN and ETRB chromatographic evaluations were carried off using the “KNAUER C18 Eurospher II column (250 mm × 4.6 mm × 5 μ)”. The mobile phase (MBP) was driven into the KNAUER C18 Eurospher II column at a 1.0 ml/min run rate with an isocratic elution programme of 65% volume of 0.5 mmol sodium perchlorate 35% volume methanol, detected and evaluated the PRBN and ETRB content at 217 nm. Results: The analysis of PRBN and ETRB is executed inside a run period of 15 min. The RP-HPLC quantifiable technique was developed to separate PRBN and ETRB and likely degradants formed from stress testing by isocratic elution. The RP-HPLC quantifiable technique developed was successfully validated to existing ICH limit guidelines and was confirmed as robust, specific, accurate, selective, precise, sensitive, and linear. Conclusion: The RP-HPLC quantifiable technique developed here is more valuable and worthy for routine PRBN and ETRB analysis of tablets and bulk kinds

    Pakshaghata is one among the Vata Nanatmaja Vyadhi, characterised by loss of function either in right or left half of the body. Pakshaghata is also considered among the ailments of Madhyama Roga Marga. Signs and symptoms of Pakshaghata is similar to that of stroke with hemiplegia as the cardinal clinical feature. It makes the affected person physically disabled and reduces quality of life. Even though western science had moved for in acute management of stroke, it is very difficult to handle the residual effect of stroke which makes person physically and mentally debilitated. In case of managing residual cases, it depends on physiotherapy and exercises, which gives good results if combined with Ayurvedic treatments such as Abhyanga. Present study is a single group open clinical trial with pre and post-test design with a sample size of 30 subjects. Subjects were administered with Shiropichu, Sthanika Abhyanga, Salvana Upana Sweda for first 10 consecutive days and Shamanaaushadha for all 30 days. The results obtained on parameter muscle power, muscle tone, finger movements and deep tendon reflexes was statistically non-significant in the management of Pakshaghata vis-Ă -vis hemiplegia. The results obtained on parameter stroke specific quality of life scale showed statistically significant result with p value 0.005 in the management of Pakshaghata vis-Ă -vis hemiplegia. Hence, it was inferred that the intervention selected for the present study possess combined effect in improving the quality of life of individual affected with Pakshaghata vis-Ă -vis Hemiplegia

    Vegetables have a critical function in human health and nutritional security. Vegetables are considered an essential building block of any diet. Out of the leafy vegetables, Amaranthus is the most popular and salable vegetable consumed by people all over India. Seed processing experiment was undertaken in Amaranthus tricolor (CO 2) by using the sieves placed inside the mechanical seed shaker (Gyratory sieve shaker) to improve the quality of Amaranthus seeds. The seeds of Amaranthus were size graded with seed shaker attached with various sieve size of BSS 18 X18 (R), BSS 20 X 20 (R), BSS 22 X 22 (R) and BSP 22 X 22 (P). During processing, the machine could be adjusted for 2, 3, 4 and 5 minutes with an oscillating speed of 1440 rpm. The separated seeds were evaluated for seed quality characteristics such as seed germination percentage, shoot length, root length, dry matter production, 1000 seed weight and seed recovery percentage. The results revealed that the sieve size of BSS 22 X 22 (R=retained) mesh sieve had the better quality seeds with a maximum recovery of 67.41 g and when it is operated for a period of 5 minutes. The germination percentage was improved from 77 % to 95 % with  1000 seed weight of 73.21 mg, and the observed recovery was 56 per cent with the vigour index of 1145. Hence, BSS 22 X 22 retained mesh sieve with a duration of 5 minutes could be recommended as an optimum sieve size for grading Amaranthus seeds for improving the seed quality

    Role of Protein Flexibility in Ion Permeation: A Case Study in Gramicidin A

    Get PDF
    AbstractProteins have a flexible structure, and their atoms exhibit considerable fluctuations under normal operating conditions. However, apart from some enzyme reactions involving ligand binding, our understanding of the role of flexibility in protein function remains mostly incomplete. Here we investigate this question in the realm of membrane proteins that form ion channels. Specifically, we consider ion permeation in the gramicidin A channel, and study how the energetics of ion conduction changes as the channel structure is progressively changed from completely flexible to a fixed one. For each channel structure, the potential of mean force for a permeating potassium ion is determined from molecular dynamics (MD) simulations. Using the same molecular dynamics data for completely flexible gramicidin A, we also calculate the average densities and fluctuations of the peptide atoms and investigate the correlations between these fluctuations and the motion of a permeating ion. Our results show conclusively that peptide flexibility plays an important role in ion permeation in the gramicidin A channel, thus providing another reason—besides the well-known problem with the description of single file pore water—why this channel cannot be modeled using continuum electrostatics with a fixed structure. The new method developed here for studying the role of protein flexibility on its function clarifies the contributions of the fluctuations to energy and entropy, and places limits on the level of detail required in a coarse-grained model
