Development of large scale drying system for Chillies(Capsicum annum)

A study was conducted to investigate large scale drying of ripe chillies in unutilized tobacco barns.  Experiments indicated that ten quintals of ripe chillies can be loaded in a 6 m×3.6 m size barn.  Galvanized iron wire mesh trays of size    105 cm×75 cm×7.5 cm were found to be suitable to spread chillies on the existing tiers.  Drying time required to reduce moisture from 292.5% to 9.6% (db) varied considerably depending upon whether chilli pods were thin pericarp type varieties or thick pericarp type hybrids.  The hybrids took about 40 hours to dry whereas the varieties took about 24 hours.  Drying air temperatures ranging initially at 50℃ to a final value of about 55℃ were found to be appropriate to dry chillies.   Open yard sun drying took 12 and 17 days for varieties and hybrids respectively.   The discoloured pods were low, 3.5%- 4% in barn dried process in comparison to 12% to 14% in open yard sun drying.  The study suggests that unutilized barns can be converted to dry ripe chillies on a large scale.Keywords: Chillies, drying, barns and large scale Citation: Satyanarayana CH.

PRONIOSOMAL GEL MEDIATED TRANSDERMAL DELIVERY OF GLIBENCLAMIDE AND ATENOLOL COMBINATION: EXVIVO AND PHARMACODYNAMIC STUDIES

Objective: The objective of the present work was to develop an optimized dosage form for treating comorbidity in combination and evaluate it for its pharmacodynamic performance in male Wistar albino rats. Methods: Transdermal proniosomal gel for Combination of Glibenclamide (GLB) and Atenolol (ATN) was developed and optimized by Box Behnken design. This optimized combinational proniosomal gel (OCPG), which was selected by a point prediction method, was evaluated for its ex vivo, skin irritation studies and pharmacodynamic activities of both drugs in rats in comparison with its oral therapy. Results: The ex-vivo permeation behavior through different skins was studied and the findings were also confirmed by the values of the steady-state flux (Jss). The OCPG observed an increase of more than twice in the cumulative amount of impregnated drugs compared to pure drug films. The study on skin irritation revealed the non-irritability of the developed OCPG applied. OCPG significantly showed sustained hypoglycemic activity in rats (p<0.001), when compared to orally treat animals up to 24 h. Systolic blood pressure (SBP) lowering effect of OCPG was found to be significant (p<0.02), when compared to orally treat rats up to 24 h. However, the reduction was slow and sustained in the case of OPCG where a significant response was observed in the performed studies. Conclusion: Overall, the results show that controlled release GLB and ATN proniosomes offer a useful and promising transdermal delivery system. Henceforth this may be an achievement in treating the diabetic hypertensive patient

The most distinct traits are automatically extracted by the algorithm from these photographs. Experimental results show that the suggested framework is effective, with an average recognition accuracy of 97.42%.The most successful SVM Kernel was RBF

Analysis and reporting of adverse drug reactions at a tertiary care teaching hospital

Objectives: To analyze and report adverse drug reactions (ADRs) in a tertiary care teaching hospital.Methods: This was an observational study, conducted to analyze and communicate the ADRs reported from July 2016 to June 2017 in a south Indian tertiary care teaching hospital. On daily basis, ADRs reported by healthcare professionals (HCPs) were analyzed and the reports that meet pharmacovigilance programme of India (PvPI) reporting criteria were communicated to PvPI through a specified updated Indian Pharmacopoeia Commission (IPC) suspected ADR reporting form. In this study, ADRs were summarised based on demographics, drug, incidence, type of reaction and its outcome. Causality, severity, seriousness, and predictability were assessed through WHO causality assessment scale, Hartwig and Siegel Severity Assessment Scale and PvPI criteria.Results: A total of 254 ADRs communicated to PvPI through specified, updated IPC suspected ADR reporting form. The incidence of ADRs in both males and females was identical. The occurrence of ADRs in adult patients (71.26%) was significantly higher than other age groups. Of total ADRs, most of them were withAntibiotics (24.01%) followed by antipsychotics (11.42%). In causality assessment, a majority of ADRs (48.82%) were considered possibly related to the drug or treatment and 55.12% were mild in severity. Overall, 36.22% patients were recovered from ADRs. Most of the reported ADRs (54.33%) were probably preventable.Conclusions: The results provided an insight to the HCPs on the importance of monitoring and reporting of ADRs. High-quality data gathered through a reporting system, most of the reported ADRs were probably preventable; the proper review of patient history and monitoring by HCPs can reduce the incidence of ADR. Our study results emphasize a need for establishing a pharmacovigilance centre to ensure the safe use of drugs.Keywords: Adverse drug reaction, Pharmacovigilance, Reporting, Causalit

A study on air-sea exchange processes and conserved variable analysis over the Indian Ocean with INDOEX IFP-99 data

The exchange properties across the Marine Boundary Layer influence atmospheric convection and determine to a large extent the atmospheric circulation in the tropics. In view of these phenomena, an analysis of the surface parameters such as sea-surface temperature, air temperature, wind speed, moisture and cloud cover along the ORV Sagar Kanya and Ronald H. Brown cruise track was carried out. An attempt was made to examine the changes in these parameters while the ship was passing across the ITCZ region. The humidity was found to be considerably high over the ITCZ than non-ITCZ regions. The air-sea interaction processes were studied by computing the radiation fluxes (short-wave and longwave) and the turbulent heat fluxes (sensible heat and latent heat) using semi-empirical models. Over ITCZ region a net heat loss was found which can be attributed to large convergence, strong convective activity and dense cloud cover, leading to drastic reduction in short-wave radiation. Latitudinal and longitudinal variation of surface meteorological parameters and turbulent fluxes were studied to establish a link with the prevailing convective and clear weather regimes along the cruise tracks. A conserved variable analysis of the conserved variable such as potential temperature, virtual potential temperature, saturation equivalent potential temperature and specific humidity is carried out at every point of upper air observation from Ronald H. Brown. The values are estimated up to a maximum of 3 km to cover the boundary layer. In the ITCZ region due to the convective mixing deeper boundary layers are formed, where a double structure is observed. The Marine Boundary Layer Height is also estimated using thermodynamic profiles

Hybrid Encryption-based Color Image Watermarking using Improved GWO with LSB

Digital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable color image watermarking (CIW) techniques have been developed to mitigate this concern. However, it is tough to achieve a watermarking system that is simultaneously robust and secure. Therefore, this article introduces the hybrid encryption (HE)-based CIW using improved grey-wolf optimizer (IGWO) with least significant bit (LSB) approach, here after denoted as HE with IGWO-LSB. Initially, the HE performed on watermark image to encrypt the data securely before embedding it into cover image. In addition, the IGWO unifies the advantages of traditional GWO with discrete cosine transform (DCT) for enhanced feature extraction in transform domain. Then, LSB approach is employed for embedding the encrypted watermark image into the cover image. Finally, the watermarked image is obtained using IDCT with postprocessing operations. The simulations carried out on standard test images discloses the superiority of proposed HE with IGWO-LSB approach as compared to state-of-art CIW approaches in terms of peak signal-to-noise ratio (PSNR), structural similarity (SSIM) index, mean square error (MSE), normalized cross correlation (NCC) and unified averaged changed intensity (UACI) values

Sensitive Bromatometric Methods for the Determination of Sumatriptan Succinate in Pharmaceutical Formulations

Abstract: Two simple and sensitive spectrophotometric methods are described for the determination of sumatriptan succinate (STS) in pure and tablets using bromate-bromide as the bromination reagent in acid medium and two dyes as subsidiary reagents. The two methods are based on the bromination of STS by a known excess of in situ generated bromine followed by determination of unreacted bromine by reacting with a fixed amount of methyl orange (Method A) or indigo carmine (Method B) and measuring the absorbance at 508 or 610 nm. In both methods, the amount of bromine reacted corresponds to the amount of STS. The experimental conditions for the assay have been optimized. In two methods, the absorbance was found to increase linearly with the concentration of STS at the respective wavelengths. Beer's law was obeyed over the ranges 0.2-1.6 and 2.0-12.0 µg mL -1 for method A and method B respectively and the respective molar absorptivity values were 1.898x10 5 and 2.71x10 4 L mol -1 cm -1 . The statistical analysis of the methods was validated according to the present ICH guidelines. The proposed methods were applied to the analysis of tablet form of STS and the results tallied well with the label claim
