Saroclazines A–C,thio-diketopiperazines from mangrove-derived fungi <Emphasis Type="Italic">Sarocladium kiliense</Emphasis> HDN11-84

Three new diketopiperazine derivatives (DKPs), saroclazines A–C (1–3) along with three known DKPs (4–6) were isolated from mangrove-derived fungi Sarocladium kiliense HDN11-84. Saroclazines A–B (1 and 2) possessed a free amide structure, which was first found in sulfur-containing aromatic DKPs. Their structures were elucidated by NMR, HRESIMS and X-ray. The cytotoxic activity of new compounds (1–3) was tested against HeLa cell lines, among which compound 2 showed an IC₅₀ value of 4.2 µM.     

Diethylstilbestrol impaired oogenesis of yellow catfish juveniles through disrupting hypothalamic–pituitary–gonadal axis and germ cell development

Diethylstilbestrol (DES), a non‐steroidal estrogen, has been found to cause altered germ cell development and disordered ovarian development in fish females. However, the mechanisms that might be involved are poorly understood. In this study, female juveniles of yellow catfish (Pelteobagrus fulvidraco) (120 days post‐hatching) were exposed to two doses (10 and 100 ng l^?1) of DES for 28 days. After the endpoint of exposure, decreased ovary weight and gonadosomatic index, as well as various ovarian impairments were observed in response to DES. Besides, DES elevated the mRNA levels of vitellogenin 1 (vtg 1) and estrogen receptor 1 (esr 1) in liver and decreased 17β‐estradiol level in plasma. Correspondingly, suppressed mRNA levels of the key genes in the hypothalamic–pituitary–gonadal axis (such as cyp19a1b, gnrh‐II, fshβ and lhβ in brain and fshr, lhr and cyp19a1a in ovary) after DES exposure were also observed. The declined level of plasma 17β‐estradiol and altered gene expressions of genes in the hypothalamic–pituitary–gonadal axis were thus supposed to be closely related to the disrupted oogenesis in DES‐treated fish. Analyses further demonstrated that, higher concentration of DES elevated the expression ratio of bax/bcl‐2, indicating the enhanced apoptosis occurred in ovary. Moreover, DES upregulated the expressions of genes involved in proliferation (cyclin d1 and pcna), meiotic entry (cyp26a1 and scp3) and meiotic maintenance (dmc1), resulting in arrested oogenesis in catfish. The present study greatly extended our understanding on the mechanisms underlying of reproductive toxicity of DES on fish oogenesis.     

Clinical and other specialty services offered by pharmacists in the community: the international arena and Israel

The community pharmacy setting is a venue that is readily accessible to the public. In addition, it is staffed by a pharmacist, who is a healthcare provider, trained and capable of delivering comprehensive pharmaceutical care. As such, community pharmacists have a colossal opportunity to serve as key contributors to patients’ health by ensuring appropriate use of medications, preventing medication misadventures, identifying drug-therapy needs, as well as by being involved in disease management, screening, and prevention programs. This unique position gives the pharmacist the privilege and duty to serve patients in roles other than solely that of the stereotypical drug dispenser.Worldwide, as well as in Israel, pharmacists already offer a variety of pharmaceutical services and tend to patients’ and the healthcare system’s needs. This article provides examples of professional, clinical or other specialty services offered by community pharmacists around the world and in Israel and describes these interventions as well as the evidence for their efficacy. Examples of such activities which were recently introduced to the Israeli pharmacy landscape due to legislative changes which expanded the pharmacist’s scope of practice include emergency supply of medications, pharmacists prescribing, and influenza vaccination. Despite the progress already made, further expansion of these opportunities is warranted but challenging. Independent prescribing, as practiced in the United Kingdom or collaborative drug therapy management programs, as practiced in the United States, expansion of vaccination programs, or wide-spread recognition and reimbursement for medication therapy management (MTM) programs are unrealized opportunities. Obstacles such as time constraints, lack of financial incentives, inadequate facilities and technology, and lack of professional buy-in, and suggested means for overcoming these challenges are also discussed.     

Improving research and policy interactions requires a better understanding of what works in different contexts

There is keen interest in many jurisdictions in finding ways to improve the way that research evidence informs policy. One possible mechanism for this is to embed academics within government agencies either as advisers or full staff members. Our commentary argues that, in addition to considering the role of academics in government as proposed by Glied and colleagues, we need to understand better how research and policy interactions function across policy sectors. We believe more comparative research is needed to understand if and why academics from certain disciplines are more likely to be recruited to work in some policy sectors rather than others. We caution against treating government as monolithic by advocating the same model for collaborative interaction between academics and government. Lastly, we contend that contextualized research is needed to illuminate important drivers of research and policy interactions before we can recommend what is likely to be more and less effective in different policy sectors.     

A neo-institutional analysis of the hidden interaction between the Israeli Supreme Court and the Ministry of Finance: the right to healthcare services

Background

Under structural conditions of non-governability, most players in the policy arena in Israel turn to two main channels that have proven effective in promoting the policies they seek: the submission of petitions to the High Court of Justice and making legislative amendments through the Economic Arrangements Law initiated by the Ministry of Finance. Nevertheless, an analysis of the principal trends emerging from the High Court of Justice rulings and legislative amendments through the Economic Arrangements Law indicates that these channels are open to influence, primarily by forces that are essentially neo-liberal. Little is known about the effects of these trends on the right to healthcare services, which in Israel has not been legislated as an independent constitutional law in Basic Laws.

Methods

We use four major legal cases decided by the Supreme Court of Israel in the past 10 years where the Court reviewed new legislative initiatives proposed by the Economic Arrangements Law in the area of healthcare. We utilize an institutional approach in our analysis.

Results

A neo-institutional analysis of the legal cases demonstrates that petitions against the Economic Arrangements Law in the area of healthcare services have been denied, even though the Court uses strong rhetoric against that law and the government more generally in addressing issues that concern access to healthcare services and reforms in the healthcare system. This move strengthens the trend toward a neo-liberal public policy and significantly weakens the legal protection of the right to healthcare services.

Conclusion

In deciding petitions against the Economic Arrangements Law in the area of healthcare, the Supreme Court allows the Ministry of Finance to be a dominant player in the formation of public policy. In doing so, it may be promoting a goal of strengthening its position as a political institution that aspires to increase the public’s trust in the judiciary and especially in the Supreme Court itself, in addition to exercising judicial restraint and allowing more leeway to the executive and legislative branches more generally.
