Recently,the experimental measurements of the branching ratios and different polarization asymmetries for processes occurring through flavor-changing-charged current(b→cτν¯_(τ))transitions by BABAR,Belle,and LHCb have revealed some significant differences from the corresponding Standard Model(SM)*** has triggered an interest to search for physics beyond the SM in the context of various new physics(NP)models and using the model-independent weak effective Hamiltonian(WEH).Assuming left-handed neutrinos,we add the dimension-six vector,(pseudo-)scalar,and tensor operators with complex Wilson coefficients(WCs)to the SM *** 60%,30%,and 10%constraints resulting from the branching ratio of B_(c)→τν¯_(τ),we reassess the parametric space of these new physics WCs accommodating the current anomalies based on the most recent HFLAV data of R_(τ/μ,e)(D)and R_(τ/μ,e)(D^(*))and Belle data of F_(L)(D^(*))and P_(τ)(D^(*)).We find that the allowed parametric region of left-handed scalar couplings strongly depends on the constraints of the B_(c)→τν¯_(τ)branching ratio,and the maximum pull from the SM predictions results from the<60%branching ratio ***,the parametric region changes significantly if we extend the analysis by adding LHCb data of R_(τ/μ)(J/ψ)and R_(τ/ℓ)(Λ_(c)).Furthermore,due to the large uncertainties in the measurements of R_(τ/μ)(J/ψ)and R_(τ/ℓ)(X_(c)),we derive the sum rules which complement them with R_(τ/μ,e)(D)and R_(τ/μ,e)(D^(*)).Using the best-fit points of the new complex WCs along with the latest measurements of R_(τ/μ,e)(D(^(*))),we predict the numerical values of the observable R_(τ/ℓ)(Λ_(c)),R_(τ/μ)(J/ψ),and R_(τ/ℓ)(X_(c))from the sum *** simultaneous dependence of abovementioned physical observables on the NP WCs is established by plotting their correlation with R_(D) and R_(D^(*)),which are useful to discriminate between various NP *** find that the most significant impact of NP results from the WC C^(S)_(L)=4C^(T).Fi

There is an urgent necessity to shift our diets toward those rich in fruits and vegetables and at reduce postharvest losses of *** 20%-50%of fruits and vegetables are lost due to poor postharvest handling and pathogen infections in developing countries while it was estimated as 5%-35%in developed countries. Fresh fruits have evolved with a plethora of microorganisms having important roles in maintaining fruit health. However, little information is available on the dynamics, structure, and functional capacities of underpinning fruit microbiomes. The present review discussed environmental conditions favoring fruit-harbored antagonists and their different modes of action for suppressing postharvest pathogens in fruits. It also provides information on omics technologies such as next-generation sequencing (NGS),metaproteomics, metatranscriptomic, and metabolomics studies to characterize fruit microbiomes. With the advent of NGS and meta-omics technologies, microbiome research could bring remarkable development and understanding in succeeding biological treatments. In addition, they may provide us with a fundamental understanding of microclimate requirements for fruit microbiome establishment and microbiome shifts during post-harvest storage, which would be advantageous in developing composite biocontrol treatments for post-harvest decay management.

作者： Aqsa Yousaf Ayesha Zafar Muhammad Ali Snober Mona Bukhary yasmeen manzoor Tuba Tariq Asma Saeed Muhammad Akram Faryal Bukhari Muhammad Abdullah Syeda Sadaf Zehra Shahbaz Gul Hassan Murtaza Hasan Department of Biochemistry and Biotechnology The Islamia University Bahawalpur Pakistan Department of Biological Sciences Gomal University Dera Ismail Khan Pakistan Department of Chemistry The Islamia University Bahawalpur Pakistan Cholistan Institute of Desert Studies (CIDS) The Islamia University Bahawalpur Pakistan Department of Botany The Islamia University Bahawalpur Pakistan College of Information Science and Engineering Zhongkai University of Agriculture and Engineering Guangzhou China

Objective: Evaluating the bio-reducing activity and various potential, annotates the biological entitties of Fagonia cretica. Method: By fractionating the crude extract with different ethanol-water fraction mixture. This substantiates the reduction potential for the biological synthesis of AgNPs, its antioxidant, anti-urease and anti-Tyrosinase activity. Results: UV-visible spectra confirm the bio-reducing potential for Ag NPs with the optimized 50% ethanol-water fraction mixture. Transmission electron microscopy (TEM) confirmed the round shaped AgNPs with an average size of 16 nm in optimized 50% fraction mixture. Further evaluating Ethanol-water fraction with 90% and 70% of plant extract showed more potentials for Anti-Tyrosinase and Anti-urease activity. Moreover, diluted 30% fraction exhibits two folds higher Anti-oxidant and Anti urease activity. Conclusion: Overall, this work showed that 50% Ethanol-water fraction has potentially active molecules (among all fractions) primarily involved in bio-reducing potential of Ag NPs and enzymatic assay while 90% mixture proved to be least active. This study suggested electing the optimum mixture fraction of 50% ethanol-water in order to screen the bioactive compounds and to inculcate their activity status for clinical trials.
