A systematic review on the effectiveness of herbal interventions for the treatment of male infertility.

Background: Male infertility is an emerging health issue in the world today. Surgical interventions for the treatment of male infertility are available but are quite expensive. Herbal interventions pose a popular alternative for the treatment of infertility. However, much has to be learned regarding their safety and efficacy. Objective: The aim of the study was to investigate the efficacy of herbal interventions in male infertility and also assess the possibility of these interventions as complementary and alternative medicine (CAM) in the future. Method: From inception until 16 December 2021, all articles emphasizing the efficacy of herbal interventions in the treatment of male infertility are included in this review. Seven databases are searched. The literature obtained is screened and extracted. Semen parameters, hormonal concentration, and conception are the outcomes of interest. Results: A total of 19 articles were included in this review. Herbal interventions might improve semen parameters in males with infertility. Among all the interventions, Hochu-ekki-to and W. somnifera have shown the most promising results and should be studied further in a larger sample size. Conclusion: This systematic review has demonstrated the efficacy of herbal interventions, especially Hochu-ekki-to and W. somnifera, in treating male infertility.

A qualitative insight into the perceptions and COVID-19 vaccine hesitancy among Pakistani pharmacists.

A qualitative exploration of pharmacists' perceptions regarding COVID-19 conspiracies and their willingness to get vaccinated. A semi-structured questionnaire guide was developed using ground theory to conduct in-depth interviews. A total of 36 participants gave consent for an audio-recorded interview. Results have shown that most of the respondents believed that SARS-CoV-2 is a natural virus, not man-made, that causes a disease just like other viruses and it is absurd to believe that the vaccine is being used by foreign powers for the implantation of microchips just to control humans. A general opinion thatwhich reflected from the in-depth interview is that the pharmaceutical companies may be hiding some important information on COVID-19 to promote the sale of their product. Some doubts on the reliability and trustworthiness on the COVID-19 vaccine safety and efficacy data were noticed among the respondents. Factors leading to COVID-19 vaccine hesitancy were adverse reaction, cost of COVID-19 vaccine, and limited data on safety and efficacy profile of COVID-19 vaccine. COVID-19 vaccine hesitancy among health professionals is a major hindrance to our current fight against COVID-19 pandemic. Findings of this study are alarming, and the stakeholders must consider this ongoing vaccination campaign as an opportunity to formulate a mechanism to ensure high vaccination rate among general public and healthcare providers in Pakistan.KEY POINTSWhat was already known?According to World Health Organization (WHO), vaccine hesitancy is one of the ten major threats to global healthcare system and it is a major barrier to achieve herd immunity around the globe.Pakistan has begun vaccinating its people in a systematic phase-wise manner under which the healthcare workers and elderly people are prioritized for vaccination.Previous experience tells us that vaccine hesitancy is a major problem in Pakistan and it is better to understand perceptions of pharmacists about COVID-19 vaccine who are the primary source of information for most of general population.What this study adds:This study is first of its kind to explore vaccine hesitancy among Pakistani pharmacists and the results of this study show that majority of the participants were willing to get COVID-19 vaccine and few of them have even got themselves vaccinated at the start of vaccination campaign.Many among the willing participants considered cost of vaccine, adverse reactions, limited data, safety, and efficacy as major hindrance to their decision to get vaccine.Few participants were found highly vaccine-hesitant because of their staunch belief in the prevalent myths and rumors about COVID-19 vaccine.

Simvastatin Nanoparticles Loaded Polymeric Film as a Potential Strategy for Diabetic Wound Healing: In Vitro and In Vivo Evaluation.

INTRODUCTION: The pleiotropic effects of statins are recently explored for wound healing through angiogenesis and lymph-angiogenesis that could be of great importance in diabetic wounds. AIMS: The aim of the present study is to fabricate nanofilm embedded with simvastatin-loaded chitosan nanoparticles (CS-SIM-NPs) and to explore the efficacy of SIM in diabetic wound healing. METHODS: The NPs, prepared via ionic gelation, were 173 nm ± 2.645 in size with a zeta potential of -0.299 ± 0.009 and PDI 0.051 ± 0.088 with excellent encapsulation efficiency (99.97%). The optimized formulation (CS: TPP, 1:1) that exhibited the highest drug release (91.64%) was incorporated into the polymeric nanofilm (HPMC, Sodium alginate, PVA), followed by in vitro characterization. The optimized nanofilm was applied to the wound created on the back of diabetes-induced (with alloxan injection 120 mg/kg) albino rats. RESULTS: The results showed a significant (p < 0.05) improvement in the wound healing process compared to the diabetes-induced non-treated group. The results highlighted the importance of nanofilms loaded with SIM-NPs in diabetic wound healing through angiogenesis promotion at the wound site. CONCLUSION: Thus, CS-SIM-NPs loaded polymeric nanofilms could be an emerging diabetic wound healing agent in the industry of nanomedicines.

Effectiveness of Pharmacological Intervention Among Men with Infertility: A Systematic Review and Network Meta-Analysis.

Background. Infertility is an emerging health issue for men. Comparative efficacy of different pharmacological interventions on male infertility is not clear. The aim of this review is to investigate the efficacy of various pharmacological interventions among men with idiopathic male infertility. All randomized control trials evaluating the effectuality of interventions on male infertility were included for network meta-analysis (NMA) from inception to 31 April 2020, systematically performed using STATA through the random effect model. The protocol was registered at PROSPERO (CRD42020152891). Results. The outcomes of interest were semen and hormonal parameters. Treatment effects (p < 0.05) were estimated through WMD at the confidence interval of 95%. Upon applying exclusion criteria, n=28 RCTs were found eligible for NMA. Results from NMA indicated that consumption of supplements increases sperm concentration levels [6.26, 95% CI 3.32, 9.21] in comparison to SERMs [4.97, 95% CI 1.61, 8.32], hormones [4.14, 95% CI 1.83, 6.46], and vitamins [0.15, 95% CI -20.86, 21.15)] with placebo, whereas the use of SERMs increased percentage sperm motility [6.69, 95% CI 2.38, 10.99] in comparison to supplements [6.46, 95% CI 2.57, 10.06], hormones [3.47, 95% CI 0.40, 6.54], and vitamins [-1.24, 95% CI -11.84, 9.43] with placebo. Consumption of hormones increased the sperm morphology [3.71, 95% CI, 1.34, 6.07] in contrast to supplements [2.22, 95% CI 0.12, 4.55], SERMs [2.21, 95% CI -0.78, 5.20], and vitamins [0.51, 95% CI -3.60, 4.62] with placebo. Supplements boosted the total testosterone levels [2.70, 95% CI 1.34, 4.07] in comparison to SERMs [1.83, 95% CI 1.16, 2.50], hormones [0.40, 95% CI -0.49, 1.29], and vitamins [-0.70, 95% CI -6.71, 5.31] with placebo. SERMs increase the serum FSH levels [3.63, 95% CI 1.48, 5.79] better than hormones [1.29, 95% CI -0.79, 3.36], vitamins [0.03, 95% CI -2.69, 2.76], and supplements [-4.45, 95% CI -7.15, -1.76] in comparison with placebo. Conclusion. This review establishes that all interventions had a significantly positive effect on male infertility. Statistically significant increased sperm parameters were noted in combinations of zinc sulfate (220 mg BID), clomiphene citrate (50 mg BID), and testosterone undecanoate and CoQ10; tamoxifen citrate and FSH were shown to improve the hormonal profile in infertile males.

IN VITRO ACETYLCHOLINESTERASE AND BUTYRYLCHOLINESTERASE INHIBITORY POTENTIALS OF JATROPHA GOSSYPIFOLIA PLANT EXTRACTS.

Inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), which breakdown acetylcholine and butyrylcholine, are considered as a promising strategy in the management of Alzheimer's disease (AD). Traditional accounts of indigenous plant Jatopha gossypyfolia suggest presence of important medicinal activities including improvement of memory functioning. To establish correlation of its use as anti-Alzheimer, AChE and BuChE inhibitory activity of extracts obtained from different parts of plant Jatropha gossypyfolia belonging to the family Euphorbiaceae were tested. Extracts from leaves, stem bark and roots were prepared by maceration. Enzyme inhibitory activity was carried out by using standard in vitro AChE and BuChE inhibition assays (Ellman's assay method) and the percentage inhibition was calculated. The results showed that roots dichloromethane fraction (65.43 ± 0.11), roots methanol fraction (62.79 ± 0.34) and leaves dichloromethane fraction (57.71 ± 0.15) showed significant acetylcholinesterase inhibitory activity compared to other fractions when compared with standard serine (91.29 ± 1.17). Similarly, butyrylcholinesterase enzyme inhibitory results showed that roots dichloromethane fraction (80.46 ± 0.44), JGLE (77.34 ± 0.34) showed significant BuChE enzyme inhibitory activity as compared to other fractions when compared with standard eserine (82.82 ± 1.09). Dichloromethane extracts showed higher enzyme inhibition comparatively. Highest AChE and BuChE inhibition was observed with leaf extracts of ethyl acetate fraction. In conclusion, the plant extracts exhibited presence of bioactive compounds with significant AChE and BuChE inhibition supporting traditional use of this herb in the management of AD. However, further investigation of the plant is required.

Microbial biotransformation of beclomethasone dipropionate by Aspergillus niger

In the present research, the steroidal anti-asthmatic drug beclomethasone dipropionate was subjected to microbial biotransformation by Aspergillus niger. Beclomethasone dipropionate was transformed into various metabolites first time from microbial transformation. New drug metabolites produced can act as new potential drug molecules and can replace the old drugs in terms of safety, efficacy, and least resistance. They were purified by preparative thin layer chromatography technique, and their structures were elucidated using modern spectroscopic techniques, such as 13C NMR, 1H NMR, HMQC, HMQC, COSY, and NOESY, and mass spectrometry, such as EI-MS. Four metabolites were purified: (i) beclomethasone 17-monopropionate, (ii) beclomethasone 21-monopropionate, (iii) beclomethasone, and (iv) 9beta,11beta-epoxy-17,21-dihydroxy-16beta-methylpregna-1,4-diene-3,20-dione 21-propionate.
