ABSTRACT
Antibiotic resistance is tricky enemy that challenges our healthcare system. It is a stealthy, adaptive and ever evolving opponent, which can take years to develop but can spread like wildfire. In this study, derivatives of chiral phthalimides were developed with this aim to control the growth of resistant strains of Klebsiella pneumonia, Escherichia coli and Pseudomonas aeruginosa by targeting their resistance causing proteins and explore their binding interaction focal points through computational docking. Total 8 novel chiral phthalimides were synthesized and its antibiogram analysis was done on Muller-Hinton Agar by disc diffusion method. Cytotoxicity studies were made to check efficacy of tested compounds on human RBCs and monitor release of hemoglobin absorbance at 540nm. By using in silico molecular approach, crystal structure of target protein was retrieved from Protein Data Bank and docked through Autodock vina and PyRx. The obtained results revealed that seven out of eight compounds have active inhibitory effects against virulent strains. Minimum Inhibitory Concentration (MIC) was measured for most potent compounds i.e., 2-(1,3-dioxoisoindolin-2-yl)-3-(4-hydroxyphenyl) propanoic acid (compound 7) and 3-(1,3-dioxoisoindolin-2-yl) propanoic acid (compound 8). Docking studies displayed a report of highest affinity binding points i.e., amino acids LYS315, ALA318, TYR150, THR262, HIS314 and ARG148 for compound 7 while ALA 318, LYS 315, ARG14 and ILE291 for compound 8.

Hypercholesterolemia is a condition with elevated cholesterol and lipid profile. It is the leading reason behind myocardial infarction and coronary heart disease. It is observed in young people as well due to a sedentary lifestyle. Triphala powder has a hypolipidemic and anti-hypercholesterolemia effect. This study was designed to investigate the effect of triphala powder against hypercholesterolemia. This study also examined Triphala powder's chemical composition. Total phenolic and flavonoid content were examined. Encapsulated 400 mg and 600 mg Triphala powder were given to treatment groups I and II. Lipid profile parameters were measured and compared at 0 weeks and 10th weeks in all groups. All results were analyzed using ANOVA in IBM SPSS Statistics 20. Results of proximate analyses have shown that Okra pod powder contains moisture 12.27%, ash 11.25%, nitrogen-free extract 45.93%, crude protein 13.37%, crude fat 2.95% and crude fiber 14.23%. Mineral analysis showed that iron and manganese are major minerals in triphala powder. Triphala powder showed a significant reduction in lipid profile parameters in hypercholesterolemia. All results are taken significantly at p<0.05.

BACKGROUND: The mountainous territory of Kohistan shelters diverse food plant species and is considered one of the important hotspots of local plant knowledge. In the era of globalization and food commodification, wild food plants (WFPs) play an important role in supporting local food systems and related local knowledge is one of the important pillars of food sustainability across the region. Since the area is populated by different cultural groups and each culture has retained particular knowledge on the local plant species, therefore, to make a cross-culturally comparison, the study was planned to record and compare the local plants knowledge among three linguistic groups viz Gujjar, Kohistani and Shina in order to not only protect the local knowledge but to determine the food cultural adaptations among these groups looking through the lens of their food ethnobotanies. METHODS: Field ethnobotanical survey was carried out in 2020-2021 to gather the data on wild food plants. We used semi-structured interviews. Use reports were counted, and the results were visualized through Venn diagrams. RESULTS: In total, 64 plant species belonging to 45 botanical families were documented. Among these Ajuga integrifolia, Barbarea verna, Clematis grata, Impatiens edgeworthii, Ranunculus laetus (vegetables), Parrotiopsis jacquemontiana (fruit), Indigofera tinctoria (flower), Juniperus excelsa, Primula elliptica, P. macrophylla (flavoring agent), Leontopodium himalayanum (Chewing gum), and Juniperus excelsa (snuff) were reported for the first time. The highest use reports (≥ 90) were recorded for Mentha longifolia, Amaranthus hybridus, Quercus semecarpifolia, Solanum miniatum, Oxalis corniculata, Ficus palmata, and Urtica dioica. Maximum number of wild food plant species (WFPs) were reported by Kohistani, followed by Shinaki and Gujjari linguistic groups. The percentage overlap of traditional knowledge on WFPs was highest among Kohistani and Shinaki (56.0%), followed by Shinaki and Gujjars (17.0%), and Kohistani and Gujjars (15.0%). Kohistani and Shinaki groups exhibited maximum homogeneity in traditional knowledge. However, Gujjars had more knowledge on WFPs compared to Kohistani and Shinaki. In addition, some dairy products viz. Bhorus, Bagora, Bak, Cholam, Kacha, Gurloo and Poyeen were reported also reported that are consumed orally and used in traditional cuisines. CONCLUSIONS: The study indicates that Kohistan is one of the important spots of biocultural diversity and could be recognized as biocultural refugia. WFPs have been an integral part of the traditional food systems among the studied groups, particularly the Gujjars have reported more distinct plant uses which could be referred to their distinctive ecological experiences among others. However, social change is one of the challenges that might lead to the erosion of local plant knowledge. Moreover, intercultural negotiations among the studied groups are also a matter of concern which could homogenize the local knowledge among them. Therefore, we suggest solid policy measures to protect the local knowledge and celebrate diversity across this mountain territory.

Personal immunity frolicked an essential role in combating COVID-19 impacts on human health individually and collectively in community. Literature represented the fact about food or nutritional supplements are certified to protect against diseases; this was the reason behind public trust on certain plants and other commercial products to boost up immunity against coronavirus disease. Present study was conducted to observe the attitude of common public towards natural herbs in treating various diseases and to assess the possible potential of herbal medication in prevention of negative impacts of different variants of COVID-19 on human health at herbal clinic named "Pakistan Matab". Results concluded that most of the patients (About 80%) avoided COVID-19 testing even on experiencing major symptoms and they preferred herbal medication. Patients who died by COVID-19 were also experiencing different diseases like liver and Kideny malfunctioning; old age was another significant factor in this case. About 90% of patients were COVID symptomatic and 10% were carrying other diseases during observational study period at herbal clinic. Study represented that patients who visited clinic, have a faith on herbal medication with about 60% of patients in favor of vaccine and allopathic medication in combination with herbal treatment. Study investigated that vaccine was only for one type of variant and use of herbal medicines could be better option to boost up immunity against various COVID variants.
