Landmark advances in rare earth (RE) chemistry have shown that divalent complexes can be isolated with non-Aufbau 4f {5d/6s} electron configurations, facilitating remarkable bonding motifs and magnetic properties. We report a series of divalent bis-tethered arene complexes, [RE(NHAr )] (2RE; RE = Sc, Y, La, Sm, Eu, Tm, Yb; NHAr = {N(H)CH-2,6-(CH-2,4,6-Pr)}). Fluid solution EPR spectroscopy gives < 2.

The opioid crisis in the United States has resulted in more than 500,000 deaths since 1999, and recent estimates suggest that attributable deaths could reach 842,000 by 2032. While heroin and synthetic products such as fentanyl now account for the majority of opioid overdoses, the prescription opioid crisis that emerged in the mid-1990s was the primary antecedent to the current situation. Recent settlements in litigation against opioid producers, suppliers and retailers has resulted in the release of almost 2.

Article Synopsis
  • - Accurate symptom monitoring is essential for managing pediatric asthma, and the CHILDHOOD ASTHMA CONTROL TEST (C-ACT) is a validated tool, but concerns exist regarding the cultural appropriateness of its response option images.
  • - A study involving interviews with children (ages 4-11) and their caregivers from the U.S., Spain, Poland, and Argentina developed and evaluated alternative response images for C-ACT, focusing on understanding and usability.
  • - The study found that while multiple alternative image scales were tested, scales A (simple faces) and B (circles of decreasing size) showed promise; however, many children struggled with ranking them correctly, indicating a need for further modifications.

Tobacco industry public relations campaigns have played a key role in challenges to standardised cigarette packaging. This paper presents a comparative analysis of industry campaigns in Australia and the United Kingdom, which have implemented standardised packaging legislation; Canada, where policy has been adopted but not yet implemented; and the Netherlands, which has considered, but not enacted regulation. Campaigns were identified via Google searches, tobacco industry websites, media coverage, government submissions and previous research; analysis focused on issue framing and supporting evidence.

In 2013, British American Tobacco (BAT) returned to Myanmar a decade after it had left the country under pressure from civil society, international organizations, and the government of the United Kingdom. The company's involvement in a joint venture with an investment branch of the country's military government between 1999 and 2003 resulted in intense scrutiny and criticism based on the military's record of human rights abuses. BAT argued that corporations could not be held accountable for actions of governments in countries in which it operated, and that its presence in Myanmar contributed to economic and social development.

Background: Smoking cessation (SC) care in the perioperative period of cardiothoracic surgery is important to reduce surgical risk and help achieve long-term smoking abstinence in patients who continue to smoke. The implementation of clinical guidelines for SC care in the perioperative period has proved challenging, yet little is known of what influences the inter-disciplinary team involved in the cardiothoracic area. This qualitative study explored the views of the clinicians involved in perioperative period of cardiothoracic surgery in Australia on their SC advice and support.
