Plant phytochemicals with known biological activity, such as antiviral, antibacterial, and anticancer properties, are crucial in treatment. It has demonstrated little to no negative effects in recent years and is regarded as safe to use. The use of medicinal plants is essential for preventing illnesses, especially cancer, which is the second leading cause of death worldwide. It was discovered that scientists had been effective in finding anti-cancer compounds up to this point such as eugenol, allicin, catechins, curcumin ursolic acid, anethol, lycopene, resveratrol, 6-gingerol from ginger, tomato, garlic, turmeric, blueberries, milk thistle, cranberries, walnuts which can assist in blocking or activating cancer cell activation signalling pathways cycloxigenase, matrix metalloproteinases MMP, COX-2, topoisomerase enzyme, Bax, Bak proteins and accelerating enzymes (antioxidant potential) that protect the body. Cancer is now treated with a few plant-based products and their phytoconstituents. Even though the management and control of cancer progression have advanced significantly, there are still many gaps and untapped prospects. As a result, this review article emphasizes the value of medicinal plants in maintaining human health as well as lists the phytochemicals from medicinal plants that can be used to cure cancer.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48573560","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}

Percentage reduction potential in different parameters i.e., pH, Electrical Conductivity (EC), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD), confirmed that these fungi had the potential to degrade oily effluents. Aspergillus niger showed the highest reduction potential, while A. flavus and R. stolonifer had the least reduction potential to treat oil pollution.

Infections, caused mainly by zoonotic agents, occur frequently due to the lack of safety monitoring regulations, as well as the inappropriate use of antimicrobial products, leading to the emergence of antimicrobial-resistant microorganisms. Pseudomonas aeruginosa, often known as the MDR pathogen has evolved resistance to multiple antibiotics. Because of its propensity to build biofilms in meat and other food products, P. aeruginosa is even more resilient to the phenomenon of drug resistance which is a major public health issue. Standard microbiological and biochemical tests were used to isolate and identify P. aeruginosa from a total of 100 meat samples (20 from each district from broiler chicken meat) gathered from various butcher shops and supermarkets. The Kirby Bauer method was used to identify antibiotic resistance, while the microtiter plate test was used to monitor biofilm formation. It was found that P. aeruginosa was identified from 22% of the broiler chicken meat samples and showed resistance to Cloxacillin, teicoplanin, ciprofloxacin, imipenem, and meropenem, followed by linezolid, streptomycin, amikacin, compound sulphonamide, aztreonam and cefepime which showed intermediate resistance. Multiple Antibiotic Resistance Index (MARI) was calculated as 0.45 for a total of 11 antibiotics. Also, all 22 MDR isolates of P. aeruginosa tested positive for the presence of the biofilm. In conclusion, it was determined that chicken meat was contaminated with Pseudomonas aeruginosa, and these strains that produce biofilms are more resistant to antibiotics. Thus, there is a serious threat to public health from biofilm-forming isolates found in broiler chickens.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43760068","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}

(Lililaceae) bears various medicinal applications that likely date back more than a thousand years ago. The current review provides an overview of the folk traditional uses, phytochemistry, biological activities, and cosmaceutical applications of the A. vera plant to date. The data have been retrieved from different scientific databases, including PubMed-Medline, Researchgate, Google Scholar, Science Direct, Scopus, SciELO, Taylor & Francis, Web of Science, books, conference papers, Masters and Ph.D. dissertations. As per the collected data of this review, almost 40 active phytoconstituents in A. vera have been reported so far with varying concentrations. Ethnobotanical data displayed that A. vera is still used as traditional medicine among communities against more than 20 different health-related problems. The DPPH, FRAP, TAC, and ABTS assays were commonly employed where A. vera extracts showed varying antioxidant activities against reactive oxygen species (ROS). Data on the biological activities showed A. vera plant extracts with remarkable anti-inflammatory activities through the inhibition of TNF-α and prostaglandin E2 factors and also exerts anti-diabetic activity against type 1 and type 2 diabetes. As per the collected data of this review, A. vera extracts have been reported with anti-microbial activities against more than 12 bacterial and 7 fungal strains and also obstruct the uncontrollable proliferation of specific types of cancer cells like HCT-116, HepG2, HeLa, A549, and MCF-7. Conclusively, A. vera possesses wide-ranging applications in the treatment of various diseases. However, more controlled investigations and clinical trials with the elucidation of the mechanism of action activities are prerequisites in the future to substantiate the outcomes and efficacies of A. vera under different circumstances. Any toxic effects of A. vera if associated with specific extracts or compounds should be addressed for safer consumption of Aloe-based food and cosmetic products.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49389623","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}

This variety is mainly developed for industrial purposes for pasta production. Worldwide, durum wheat is utilized for pasta production; but in Pakistan, due to a lack of research work and non-availability of quality seeds of durum wheat, bread wheat is being utilized for pasta production. D-21 is developed with the breeding code of D-21 having parentage of FKN/3/2*FR//KAD/GB/4/BB/CHA/5/AS-2002 with pedigree as PB20733-1a-2a-2a-0a-0a-19a-0a. The candidate line D-21 was developed by crossing a germplasm accession with approved bread wheat variety AS-02. The genotype was further evaluated over multiple locations in Punjab Pakistan for yield and yield-related attributes in the station, provincial, and national uniform durum yield trials executed by Wheat Research Institute (WRI), Faisalabad during 2015-20. The promising line out yielded the two commercial check varieties D-97 and Fsd-2008 by 1.42 % in the provincial yield trial and 4.2 % in the national yield trial.

The total municipal area of Skardu is about 4260 sq. km with a population of approximately 112996. In line with other government departments, the Gilgit Baltistan waste management company (GBWMC) is responsible for collecting and dumping solid waste. The current study was devised to calculate, characterize, and analyze the past status, and current position of municipal solid waste (MSW) production, so that necessary management practices and corrective measures can be carried out more efficiently in the study area. A series of interviews of concerned persons as well as extensive field surveys were conducted. The method used by GBWMC to collect waste was: door-to-door collection, placement of waste bins, and collection from the arterial roads. Waste was collected manually in polythene bags, handcarts, and baskets. The findings revealed that approximately 45-50 tonnes of waste was generated per day in the winter and in the summer it increases to 50-55 tonnes. The average waste generation was 0.43 kg per capita per day and is increasing at a rate of 2.28% annually. The main sources of waste were commercial and household waste contributing approximately 60 % and 40% of the total waste production respectively.  There was no scientific disposal system for the collected waste which is dumped on the dumping sites by utilizing available resources considering Environmental protection agency (EPA) regulations along the Indus River bank. Thus specific steps should be taken to develop a proper scientific disposal system of collected wastes by incorporating the experts' expertise and modern technologies.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44170059","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}
