Effect of Chemicals and Growth Regulators on Post-Harvest Shelf-Life and Quality in Papaya (Carica papaya L.) Cv. Red Lady
The present investigation on papaya (Carica papaya L.) cv. Red Lady was carried out at Horticultural College and Research Institute, Venkataramannagudem, West Godavari district of Andhra Pradesh, during the year 2010-11. The study was carried out using 9 different treatments involving two chemicals calcium nitrate and calcium chloride at 1, 2, 3 and 4% concentration and two growth regulators, viz., GA3 at 75, 100, 150 and 200mg/l, and BA at 100, 125, 150 and 175mg/l concentration conducted separately in a factorial concept of completely randomized design (CRD), with three replications, under laboratory conditions. Physical parameters studied were per cent fruit ripening, physiological loss in weight (PLW), fruit firmness, shelf-life, and, physic-chemical properties studied were: total soluble solids (TSS), total sugars, reducing sugars, acidity, ascorbic acid and Brix:acid ratio. Fruits treated with CaCl2 @ 4% showed significantly low PLW, per cent fruit ripening, and the highest fruit-firmness, shelf-life, lowest total soluble solids, total sugars, reducing sugars, Brix:acid ratio, and highest acidity and ascorbic acid content, which were on par with CaCl2 @ 2% application. Fruits treated with GA3 @ 100mg/l also exhibited similar results for these parameters. It was concluded that CaCl2 @ 4 % had a beneficial impact on shelf-life of papaya fruits upto 10.67 days without any loss in either physical or physic-chemical properties. Similarly, application of growth regulators such as GA3 and BA @100mg/l significantly increased shelf-life of papaya fruits upto 12 days and 11 days, respectively, while showing the best physical and physico-chemical properties
Method development and method validation of guaifenesin and dextromethorphan by RP-HPLC
A new, simple, precise, accurate and reproducible RP-HPLC method for Simultaneous estimation of bulk and pharmaceutical formulations. Separation of Guaifenesin and Dextromethorphan was successfully achieve THERMO, C18, 250X4.6mm, 5”m or equivalent in an isocratic mode utilizing 0.1M KH2PO4: Methanol (60:40) at a flow rate of 1.0ml/min and eluate was monitored at 280nm, with a retention time of 3.259 and 4.164 minutes for Guaifenesin and Dextromethorphan respectively. The method was validated and there response was found to be linear in the drug concentration range of 50”g/ml to150 ”g/ml for Guaifenesin and 50”g/ml to150 ”g/ml for Dextromethorphan. The values of the correlation coefficient were found to 0.999 for Guaifenesin and 1for Dextromethorphan. respectively. The LOD and LOQ for Guaifenesin were found to be 0.597 and 1.991 respectively. The LOD and LOQ for Dextromethorphan were found to be 0.1072 and 0.3572 respectively. This method was found to be good percentage recovery for were found to be 99 and 100 respectively indicates that the proposed method is highly accurate. The specificity of the method shows good correlation between retention times of standard with the sample so, the method specifically determines the analyte in the sample without interference from excipients of tablet dosage forms. The method was extensively validated according to ICH guidelines for Linearity, Accuracy, Precision, Specificity and Robustness

Filthy operative rooms and other mistakes during movies on neurosurgical procedures: Fascinating and powerful neurosurgical scenarios presented, in different ways, to non-neurosurgical society. How many mistakes and stereotypes can be made in movies for people not daily involved in medical life?
Objectives: The brain and people âmanipulatingâ it, provide a very mysterious and fascinating substrate for a movie. Faithful representation of reality often represent a key for the success of a film. Nonetheless, while watching movies with neurosurgical scenes, we often observed actions and elements containing incredible errors that aroused opposing emotions. The aim of this study was to perform an extensive review examining the representations of neurosurgery in movies, especially focused on the analysis of neurosurgical gross mistakes. Patient and methods: We looked for any movie that featured a neurosurgeon or a scene including a neurosurgical disease or procedure. We used one of the largest internet movie databases available online (IMDb.com) with searching for keywords such as âneurosurgeonâ, âneurosurgeryâ, and âcraniotomyâ. Title, year, genre and cost of production were collected. The first three features were detected on IMDb.com; the costs of production were found in websites the-numbers.com and boxofficemojo.com. Analysis and selection were performed by AM and PDB. Result: 73 movies were found. After the application of inclusion/exclusion criteria, 58 have been eligible for inclusion in the study (Table 1) and 15 have been excluded from the final analysisâ. Out of 45 movies watched, we found 32 neurosurgical mistakes. Mistakes were classified into four big groups, namely: âsurgical asepsis and principles of sterile techniqueâ (n = 13, 40 %); âconceptual mistakes (n = 10, 31.5 %)â; âincorrect use of surgical tools (n = 7, 22 %)â; âanatomical and radiological mistakes (n = 2, 6.5 %)â. The costs of production started from 11.000 US dollars (Vsivaci, 2014) to 200 millions dollars (Spiderman 2, 2004), with a median value of 8.2 millions dollars each. All mistakes were not useful for the correct progress of the movie. Conclusion: Our review shows that several mistakes, especially on asepsis during surgery are present in films dealing with neurosurgery. Several movies costed up to millions of dollars. Would a consultation of a Neurosurgeon before/during the shooting narrow the gap between the reality and fiction

A Localized Bloom Filter-Based CP-ABE in Smart Healthcare
Wearable technology-supported cloud-based smart health (s-health) has emerged as a promising answer to increase the efficiency and quality of healthcare as a result of rapid improvements in Internet of Things (IoT) technologies. However, the issues of data security and privacy preservation have not been fully resolved. In recent years, ciphertext policy attribute-based encryption (CP-ABE), which was developed as a versatile and potent cryptographic fundamental to accomplish one-to-many encryption with fine-grained access control, has been seen as a viable answer to the security issue in the cloud. The attribute values in the access policy, however, are supplied in cleartext in standard CP-ABE. This will conveniently reveal the data owners’ privacy (patients). Because the Internet of Things (IoT) in healthcare stores sensitive data in the cloud, security is crucial. The data must always be accessed via an access key when using traditional encryption techniques. Though the data cannot be accessed right away in an emergency, this offers greater security. The healthcare IoT created the break-glass concept to address this. The encryption technique is integrated with the broken glass idea to offer data protection and simple access in emergency scenarios. The majority of research papers employ cypher text policy attribute-based encryption (CP-ABE) with the broken glass idea to secure electronic health records. For improving data accessibility in the smart healthcare environment, modified cypher text policy attribute-based encryption (MCP-ABE) with the broken glass (BG) technique is suggested. Greater information security is achieved with this method, but the access policy is also dependent on keys that are vulnerable to hacking. To analyze the access policy individually throughout the key generation process, the attribute-based encryption procedure in this case uses the bloom filter. Information about the access policy is kept intact, which enhances the security of the keys. To continue serving patients and saving their lives, this modified CP-ABE is integrated with break glass in the smart healthcare facility. The experimental results demonstrated that, when compared to the lightweight break-glass procedure, the proposed solution is likewise the best in terms of decreased overhead. The main benefit of this strategy is that it uses the bloom filter concept in the MCP-ABE process, which protects the access policy attributes, to ensure that the key is never compromised. For data access in smart healthcare to preserve patients’ lives, the proposed MCP-ABE with broken glass is best
