Aims: The study was aimed to investigate the effect coloured polythene bags on fruit quality of ‘Himsagar’ mango grown in New Alluvial Zone of West Bengal, India. Methodology: Field experiment was conducted at Regional Research Station, New Alluvial Zone, Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal, India (22°56″ N, 88°31″ E and 9.75 m above mean sea level) during the period from 2017 to 2018. The experiment was laid out in completely randomized block design (RBD) having six distinct bagging treatments (T1- Blue polythene bag, T2- Green polythene bag, T3- Yellow polythene bag, T4-Red polythene bag, T5- White polythene bag, and one control i.e. T6- No bag), replicated four times. Fruit physical parameters, bio-chemical parameters, physiological loss in weight and disease incidence % at different days of storage were analyzed in this experiment.      Results: Experimental findings showed that among different colour of bags, green colour (T2) proved most effective as most physical parameters and bio-chemical constituents of fruit were improved in this treatment. Fruits at 8 days storage at ambient room temperature showed maximum total soluble solids, total sugar and β-carotene content with the application of green colour bag. This treatment also exhibited less physiological loss in weight (PLW) with minimum incidences of post harvest diseases during storage at ambient room temperature. Conclusion: Findings from this study show that fruit bagging with green polythene bag proved most effective in increasing the fruit weight and bio-chemical constituents of mango with less incidence of diseases that ultimately leading to better consumer acceptance and gives higher return to the growers.

Recent research supports the use of cold IV fluid as a method for initiating therapeutic hypothermia in post-cardiac arrest resuscitation. However, prehospital care programs employing this treatment have encountered various difficulties. Barriers to prehospital induced hypothermia protocols include the lack of effective or economically reasonable methods to maintain cold saline in the field. Objective. Determine the time that a standard commercial cooler can maintain two 1-liter normal saline solution (NSS) bags below 4°C in 3 different environments. Methods. Environments simulating an ambulance compartment were created for the experiment. NSS temperatures were continuously recorded inside a standard commercial cooler with or without ice packs (IPs) under one of three scenarios: ambient room temperature (25°C) without (IPs), ambient room temperature with IPs and 50°C ambient temperature with IPs. Four trials under each condition were performed. Time to warm to 4°C was compared using Kaplan-Meier log rank test. Results. In a room temperature environment with IPs, the NSS warmed to 4°C in a mean interval of 29 hrs 53 mins versus in ambient room temperature without IPs (1 hr 21 mins) versus in constant hot environment of 50°C with IPs (10 hrs 50 mins). A significant difference was found between the three environments (log-rank =17.90, dF =2, p =0.0001). Conclusions. Low technology methods in the form of a cooler and IPs can provide cold NSS storage for longer than a full 24 hour shift in a room temperature ambulance. In hot ambient conditions, 4°C NSS can be maintained for nearly 11 hours using this method. This model exhibits an economical, easily deployable cold saline storage unit.

Irrigation and fertilizer are the most dominating factors, in deciding the keeping quality of potato. It is, therefore, essential to formulate the efficient, reliable and economically viable irrigation management strategy with the use of potassium nutrient in order to produce better keeping quality. The investigation comprising four levels of irrigation (25, 30, 35 and 40 mm CPE (Cumulative pan evaporation) and four levels of potash (0, 100, 125 and 150 kg/ha) was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, (Haryana) Hisar, India during two years to find out the optimum level of irrigation and potash for obtaining higher yield of potatoes with better keeping quality at ambient room temperature. The potato variety used for the investigation was Kufri Bahar. The treatments were laid out in a split plot design with three replications. The increasing levels of irrigation and potash showed significant improvement in keeping quality parameters of potato. Likewise, the values for physiological loss in weight and decay loss of potato tubers (%) at 15, 30, 45 and 60 days after harvest were the lowest with irrigation level 40 mm CPE and application of potash @ 150 kg/ha. The two years results suggest that the irrigation level 40 mm CPE along with potash @ 150 kg/ha has shown the best treatment combination for the storage of potato at ambient room temperature under semiarid conditions of Hisar (Haryana).

BACKGROUND: Palonosetron HCl is a selective 5-HT3 receptor antagonist used for the prevention of chemotherapy-induced nausea and vomiting. Palonosetron HCl may be administered with other drugs by Y-site administration, including doxorubicin HCI and epirubicin HCI. Consequently, stability and compatability information are needed to verify the acceptability of such Y-site administration. OBJECTIVE: To evaluate the physical and chemical stability of undiluted palonosetron HCl 50 μg/mL with doxorubicin HCl 1 mg/mL and epirubicin HCl 0.5 mg/mL during simulated Y-site administration. METHODS: Triplicate samples of palonosetron HCl with each of the anthracycline chemotherapy drugs were tested. Samples were stored and evaluated for up to 4 hours at room temperature near 23°C. Physical stability was assessed using turbidimetric and particulate measurement, as well as visual inspection. Chemical stability was assessed by HPLC. RESULTS: All of the admixtures were clear and red—orange when viewed in normal fluorescent room light and with a Tyndall beam. Measured turbidity and particulate content were low initially and remained low throughout the study. The drug concentration was unchanged in any of the samples throughout the study. CONCLUSIONS: Palonosetron HCl is physically and chemically stable with doxorubicin HCl and epirubicin HCl during simulated Y-site administration of these drugs over 4 hours at ambient room temperature.

The use of natural products as coatings to preserve the fruit quality during storage is an important step to maintain food safety for consumer health. The use of microalgae in coatings, therefore, may be promising in the preservation of mango. The present work had the objective to evaluate the effect of coatings based on Chlorella sp. on the postharvest preservation of ‘Tommy Atkins’ mango during storage at room temperature (23 °C). We carried out a completely randomized design experiment consisting of 0%, 1%, 2%, 3% and 4% of Chlorella sp., using 10 fruits per treatment (n = 10). Analyzing the L*, a* and, b* indices, in the peel and the pulp of the mango fruit, we observed a delay in the ripening with the increase of the biofilm concentration. The firmness of the pulp and maintenance of the organic acids of the fruits were higher in the treatments with a large amount of Chlorella sp. The use of biofilm with Chlorella sp. at 2% preserved the quality of ‘Tommy Atkins’ mango until ten days of storage, at 23 °C and 42% RH.

The density of herbaceous crops creates a suitable environment to produce pathogens in the soil that intensify the attack of pathogens traditionally controlled by disinfectant, which are mostly prohibited and unlisted because of their toxicity. Grafting is an alternative technique to enhance abiotic stress tolerance and reduce root diseases due to soil-borne pathogens, thus enhancing crop production. This research study was conducted during the crop season of 2017 and 2018 in order to investigate the interactive effect of different grafting techniques of hybrid scion onto local rootstocks on plants survival, plant phenological growth, fruit yield and fruit quality under a controlled environment. The hybrid cucumber was also planted self-rooted. The cucumber (Cucumis sativus L.) cv. Kalaam F1, Syngenta was grafted onto four local cucurbitaceous rootstocks; ridge gourd (Luffa operculate Cogn.), bitter gourd (Momordica charantia L.), pumpkin (Cucurbita pepo L.), bottle gourd (Lagenaria siceraria (Molina) Standl.) using splice grafting, tongue approach, single cotyledon and hole insertion grafting techniques and self-rooted hybrid cucumber under greenhouse conditions. The experimental results indicated that all local cucurbitaceous rootstocks showed a high compatibility with hybrid cucumber scion in the splice grafting method compared to other grafting and non-grafted methods. Lagenaria siceraria rootstocks were found highly compatible with cucumber cv Kalaam scion which gave significantly maximum plant survival rates (95%) due to high sap contents, high SPAD value, better vegetative growth and maximum fruit yield when compared with other rootstocks by employing the splice grafting method followed by tongue approach, single cotyledon and hole insertion grafting while the fruit quality of all rootstocks was observed to be similar. The non-grafted cucumber cv. Kalaam F1 showed significant results of plant vegetative growth, fruit development and fruit quality and encountered grafting methods while the lowest result were associated with the hole insertion grafting method in all scion/rootstock combinations. The grafted plants have no significant effect on cucumber fruit dry matter and fruit quality while the fruit mineral compositions (N, P, K, Ca and Mg) were higher among grafted and non-grafted plant fruits. The results indicate that grafting hybrid cucumber onto four local cucurbitaceous rootstocks influenced growth, yield and fruit quality. Grafting can be alternative and control measure for soil-borne disease and to enhance cucumber production.

The Stability

The stability of donepezil in an extemporaneously prepared oral liquid was studied. An aqueous liquid formulation of donepezil was prepared by reconstituting the powder from triturated 5-mg tablets with equal amounts of deionized water and 70% sorbitol solution with an expected donepezil concentration of 1 mg/mL. Polyethylene terephthalate plastic bottles containing donepezil liquid preparation were stored at ambient room temperature (22° C-26° C) and in the refrigerator (4° C-8° C). After a storage time of 1, 2, 3, and 4 weeks, donepezil liquid samples were analyzed in triplicate for donepezil concentrations by high-performance liquid chromatography. The concentrations of donepezil were found to be within the acceptable limit (± 10% of the initial concentration) in all test samples, which indicated that donepezil liquid preparation was stable at room temperature and in the refrigerator for up to 4 weeks. In addition, our study findings indicated that there was no microbial growth in the extemporaneously prepared donepezil liquid preparation after a storage period of 4 weeks in the refrigerator. In summary, the results of our study revealed that donepezil is stable (no significant loss of donepezil concentration and no microbial growth) in an extemporaneously prepared oral liquid when stored in the refrigerator for up to 4 weeks.
