B. Ceiba is an enormous, stunning, and deciduous tree and native for Northern Australian origin. The present study was based on the extraction, isolation of chemical compounds and evaluation of wound healing activity of Bombax ceiba plant. The chemicals and instruments were obtained from the certified manufacturer and suppliers only. B. ceiba roots and flowers were collected and authenticated from a Botanist at MJPRU Bareilly. The extraction process was done by maceration process. Pharmacological (wound healing) potential was evaluated by wound contraction, re-epithelization, and histopathology. The n-hexane, chloroform, ethyl acetoacetate and methanol extracts of B. ceiba were examined for its phytoconstituents. Wistar rats weighing 130-210g were obtained from the Dept. of Pharmacy, MJP Rohilkhand University Bareilly. The % yield was obtained as 59% for n-hexane, 62% for chloroform, 58% for ethyl acetoacetate and 65% for methanol. According to the preliminary phytochemical analysis, the methanolic B. ceiba extracts showed excellent phytoconstituents of alkaloids, flavonoids, glycosides, carbohydrates, etc. when compared with other solvents extracts. In results, all the groups of animals showed an excellent wound healing activity when compared with control group after 15th day of exposure with treatments. The B. ceiba N-hexane, chloroform, ethyl acetoacetate, and methanol demonstrated rats showed the re-epithelization period of 11.20±0.62**, 12.17±1.30***, 9.3±1.23** and 10.4±1.12***, respectively. It is concluded that each of these has considerably exhibited wound healing potential. It suggests, to isolate the active constituent responsible for the activity.","PeriodicalId":16728,"journal":{"name":"Journal of Pharmaceutical Negative Results","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70924441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, it is difficult for us to predict or analyse these facts in order to uncover hidden knowledge that is valuable. For forecasting medical analysis, many machine learning methods and tools are employed. The most prevalent and well-known malignancy, particularly among women, is breast cancer. It ranks among the leading global causes of death. The sole remedy is early detection, which lowers the mortality rate from breast cancer. Breast cells can develop into cancer, which is known as breast cancer. Breast cancer has recently become a highly serious disease, not just in India but also in other nations. The primary goal of this research is to diagnose breast cancer patients as early as possible. Three machine learning approaches Decision Tree, Support Vector Machine, and Logistic Regression are employed for the early detection and prevention of breast cancer patients. These techniques help reduce waiting times and human and technical errors in breast cancer diagnosis. By employing these methods, we can increase the number of lives saved and decrease the death rate by maximising early diagnosis of breast cancer. The likelihood that an infection will be successfully treated depends on precisely identifying and locating it as soon as possible using logistic regression and SVM. A significant obstacle to the diagnosis of breast cancer is the classification of the appropriate machine learning technique. Thus, in order to analyse risk levels that contribute to prognosis, we developed a model for a breast cancer early prediction system. Doctors can diagnose breast cancer using this experimental study, and patients can benefit from early therapy to prolong their lives.","PeriodicalId":16728,"journal":{"name":"Journal of Pharmaceutical Negative Results","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48119771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chloramphenicol Streptomycin and tetracycline are the three main antibiotics that are used for plague treatment. Even if antibiotics are given right away, 16% of people with bubonic plague and more than 50% of people with pneumonic plague die. The number of plague cases and epidemics over the past 15 years has increased to the point where the disease is now considered reemerging. Researchers have discovered that some strains of the plague are immune to the most effective medications now in use to treat the disease. Y. pestis is worrisome since there is no effective vaccination, it must be treated with antibiotics, and it has a history of being used as a bioweapon. Antibiotic-resistant bacteria are a worldwide problem. It has been revealed that two strains of Y. pestis are highly resistant to eight antimicrobial medicines used for cure. Additionally, it is resistant to a number of commonly used antibiotics, including ampicillin, kanamycin, and spectinomycin.

Tamper-proof data and avoidance of the centralized record-keeping mechanism are crucial requirements in any wellness system due to its exigent and precise necessity of data requests. Along with the same, transactions’ auditability and revocation of access rights upon certain records for specific stakeholders are also a few of the other prerequisites in the medical segment. Blockchain, as a distributed ledger, offers a solution for securely storing data while providing transparency in transactions and interactions among stakeholders. Synchronous interaction among patient, doctor, pharmacy, consultant, hospital, etc. with all possible data security is another concern that could be resolved through the usage of Blockchain’s smart contracts wherein interaction among these stakeholders is permitted in a traceable and irreversible mode. The purpose of this paper is to discuss the potential use of Blockchain technology in the healthcare sector to achieve data security, transparency, and reliability without the involvement of a trusted third party. In terms of security and privacy, we survey and provide an exhaustive review of Blockchain-based access control systems for the healthcare system.

Despite that, silicon SDL and PMMA have different molecular structures so that they have a low bond strength. Long-term use can also affect the bond strength, so there is a need to increase the bond strength between PMMA and SDL. A method to increase the bond strength is surface treatment. This study is conducted to determine the effect of surface treatment and thermocycling on the bond strength of PMMA and Silicon SDL. Methods: The study used 40 samples (8 groups) divided into 4 groups based on the surface treatments, namely no surface treatment, sandblast, adhesive primer and combination, and further divided into two groups of thermocycling and without thermocycling treatment. The bond strength between PMMA and SDL was tested with tensile test by using Universal Testing Machine (UTM). Results: One-way ANOVA analysis showed there were significant differences of the bond strength among all groups (p <0.05) where the adhesive primer showed the highest value in all treatment groups.
