The droplet size, polydispersity index, self-emulsification time, and equilibrium solubility of the optimized formulation were 58.500 ± 1.170 nm, 0.228 ± 0.012, 17.660 ± 1.520 s, and 34.180 ± 1.380 mg/mL, respectively. Its zeta potential, transmittance value, and cloud point were - 28.200 ± 1.200 mV, 99.200% ± 0.600, and 90 °C, respectively. Drug release was found to be 93.320% ± 1.090. In vivo anti-inflammatory study confirmed more enhanced activity from the self-nanoemulsifying drug delivery system than with pure plumbagin. Pharmacokinetic study in rats revealed that solid self-nanoemulsifying drug delivery system had 4.49-fold higher bioavailability than pure plumbagin. Ex vivo permeation study demonstrated 1.75-fold increased intestinal permeability of the self-nanoemulsifying drug delivery system than pure plumbagin. The developed self-nanoemulsifying drug delivery system is a useful solid platform for improving solubility and oral bioavailability of plumbagin.The content of ursolic acid and oleanolic acid was determined in different plant parts of two Glechoma species, G. hederacea and G. hirsuta. To achieve optimal extraction conditions of ursolic acid and oleanolic acid from plant material, several methods including maceration, heat reflux, Soxhlet, and ultrasonic extraction, as well as various solvents (methanol, dichloromethane, ethyl acetate), were investigated and compared.For the simultaneous quantification of pentacyclic triterpenes in extracts from Glechoma sp., an UPLC-MS/MS was developed and validated. The method exhibited good linearity, precision, and recovery, and it also was simple, specific, and fast. We developed the method for future application in the quality control of plant materials and botanical extracts containing ursolic acid and oleanolic acid. With regard to the triterpene constituents, both G. hederacea and G. hirsuta can be used equally, and the aboveground parts of both species, but the leaves especially, are abundant sources of ursolic acid (7.1 - 7.5 mg/g dry weight [DW]). Dichloromethane as an extractant provided the best extraction efficiency as well as selectivity to obtain Glechoma extracts rich in triterpenes as compared to methanol and ethyl acetate, regardless of the particular extraction technique. Dry dichloromethane extracts from aerial parts of Glechoma sp. obtained by the heat reflux method resulted in products with a high content of UA (17 - 25% w/w) are considered to be convenient and rich sources of this compound.The incidence of chemical assault is increasing globally. In response, a number of countries are proposing legislation. selleck chemicals However, current legislative initiatives are uncoordinated and do not address the spectrum of activities to prevent and care for victims of chemical assaults. To fill this gap, we aimed to review legislation, policies and regulations relevant to chemical assault to classify and catalogue current strategies into a legislative framework. Terms related to chemical assault were used to systematically search the academic, lay and legal literatures. Chemical assault was defined as the use of acid or another caustic or corrosive substance or vitriol by one person against another with the intent to injure or disfigure. Reports that described the use of chemical weapons in warfare were excluded. A second search of national legislations of countries with reports of chemical assaults was performed to identify enacted laws and gaps in legislative approaches to chemical assault control. Data regarding rethis legislative framework to control the growing epidemic of chemical assault.The issue of time horizons has received scant attention in discussions pertaining to health economic evaluations unlike discounting or translation of health outcomes into life-cycle measures (e.g. quality-adjusted life years or disability-adjusted life years). The available guidelines do not offer clear and consistent guidance for many problems addressed in health economic evaluations. In practice, variation of time horizons between studies for the same diseases is a matter of concern, as results on cost-effectiveness depend on the time horizon. Our paper contributes to establishing a consistent approach to setting time horizons across common types of health economic evaluations and mitigating potential bias where the choice of a time horizon may affect results of the evaluation. We find that available guidance is clear only for patient-focused interventions, but not in the presence of population-level effects owing to transmission of infections or other linkages. We distinguish between a policy period-over which an intervention is delivered or initiated-and an evaluation period over which the effects are measured. One important challenge in establishing a time horizon for evaluation is that, at least for infectious diseases, the state of the epidemic at the end of the policy period cannot be evaluated precisely and incorporated in the results of an economic evaluation. While longer policy periods partly mitigate this challenge, they are subject to greater uncertainty, and outcomes may not adequately reflect the cost-effectiveness of current policies because outcomes reflect an average over the policy period. Incremental analysis on interventions implemented in sub-periods of the policy period (especially at the beginning) potentially improves accuracy and helps to identify potential for improving cost-effectiveness by varying the path of implementation or the mix of interventions offered over time.In many low-and middle-income countries, health systems decision-makers are facing a host of new challenges and competing priorities. They must not only plan and implement as they used to do but also deal with discontented citizens and health staff, be responsive and accountable. This contributes to create new political hazards susceptible to disrupt the whole execution of health plans. The starting point of this article is the observation by the first author of the limitations of the building-blocks framework to structure decision-making as for strengthening of the Moroccan health system. The management of a health system is affected by different temporalities, the recognition of which allows a more realistic analysis of the obstacles and successes of health system strengthening approaches. Inspired by practice and enriched thanks a consultation of the literature, our analytical framework revolves around five dynamics the services dynamic, the programming dynamic, the political dynamic, the reform dynamic and the capacity-building dynamic.
