Combining experiment and theory, the mechanisms of H2 activation by the potassium-bridged aluminyl dimer K2[Al(NON)]2 (NON = 4,5-bis(2,6-diisopropylanilido)-2,7-di-tertbutyl-9,9-dimethylxanthene) and its monomeric K+-sequestered counterpart have been investigated. These systems show diverging reactivity towards the activation of dihydrogen, with the dimeric species undergoing formal oxidative addition of H2 at each Al centre under ambient conditions, and the monomer proving to be inert to dihydrogen addition. Noting that this K+ dependence is inconsistent with classical models of single-centre reactivity for carbene-like Al(I) species, we rationalize these observations instead by a cooperative frustrated Lewis pair (FLP)-type mechanism (for the dimer) in which the aluminium centre acts as the Lewis base and the K+ centres as Lewis acids.

Background: Patients in the intensive care unit (ICU) frequently develop hyperactive delirium, which may be accompanied by behaviour that increases clinical risks to themselves as well as other patients and staff. There is a paucity of evidence to inform the urgent enteral administration of antipsychotic drugs to treat such hyperactive delirium and behavioural disturbances.

Objective: The aim of this study is to test the efficacy and safety of administering enteral olanzapine when compared to quetiapine in critically ill patients with hyperactive delirium.

The innate immune system plays an important role in the defense against pathogens, whereby the ability to rapidly mount an effective inflammatory response is critical in the elimination/containment of the infection. To better understand the nature of the inflammatory responses to bacterial components in chickens, we used the growing feather (GF) cutaneous bioassay together with blood sampling to examine the local and systemic inflammatory responses initiated by intradermal (i.d.

Background: Pathogen reduction (PR) may be used as an alternative to gamma or x-ray irradiation (I) to prevent transfusion associated graft versus host disease (TA-GVHD) if the pathogen reduction technology has been shown to inactivate residual lymphocytes. However, as I is considered the gold standard for reducing the risk of TA-GVHD, some centers continue to perform I in addition to PR. This study investigated the effect of concurrent pathogen reduction and irradiation (PR/I) on the biochemical characteristics of apheresis platelets at day 1, 5, and 7 of storage at room temperature.

Article Synopsis
  • Multiply-bonded main group compounds from groups 13-15, like dialumenes, are gaining attention for their unique metal-metal bonding and potential applications in catalysis and small molecule activation.
  • The study focuses on the simplest dialumene, AlH, analyzing its electronic structure and bond dissociation energy using advanced quantum chemistry methods to set a reference for other computational techniques.
  • The results show that while single-reference coupled cluster theory can effectively capture the diradical character of dialumene, density functional methods struggle with accuracy, though some approaches like non-hybrid TPSS yield better results than high-percentage hybrids.

"Functional speech" by 5 years of age is widely established as increasing the probability of long-term positive outcomes across a range of domains for autistic individuals. While terms such as "functional" or "useful" speech are often used, what defines these terms is not well established. Furthermore, most research focusing on language development has emphasized the transition from little or no language to use of single words, but much less is known about the transition from single words to phrase speech, which could be equally important.

Tumor immune resistance is recognized as a contributor to low survivorship in pancreatic ductal adenocarcinoma (PDAC). We developed a novel murine model of spontaneous PDAC clearance, generated by overexpressing interleukin-6 (IL-6) in orthotopically implanted PDAC cancer cells (OT-PDAC). Circulating IL-6 was 100-fold higher in OT-PDAC than in OT-PDAC mice.

  • Despite the availability of lipoprotein-lowering medications, some high-risk patients with persistent high cholesterol may need alternative treatments like lipoprotein apheresis (LA).
  • LA is particularly beneficial for individuals with familial hypercholesterolemia and not only lowers cholesterol but also improves heart function and reduces inflammation.
  • While studies show LA leads to better cardiovascular outcomes, its use in the U.S. is limited, and more research is needed on its benefits for certain kidney conditions.

Article Synopsis
  • Drought events are becoming more common in grasslands and shrublands, affecting soil organic carbon (SOC), which includes different forms like particulate (POC) and mineral-associated organic carbon (MAOC).
  • A global study over 19 sites revealed that in wetter areas (aridity index > 0.65), extreme drought led to a significant decrease in SOC (7.9%) and POC (15.9%), but MAOC levels remained unchanged.
  • In drier regions (aridity index < 0.65), drought did not significantly affect any type of soil organic carbon, indicating that the impact of drought on SOC is influenced by environmental aridity and rainfall variability.

Internet and Communication Technologies (ICTs) can foster efficient communication and knowledge acquisition, but there are also tradeoffs in terms of risks to one's privacy. Previous research, including work with the privacy calculus framework, indicates that factors such as perceived risks and benefits of using ICTs, ICT trust, and general privacy concerns can influence individuals' digital privacy-related decisions. One pervasive psychological factor that may potentially alter such privacy-related behaviors is acute stress.
