Unsaturated charge-neutral silicon clusters (siliconoids) are important as gas-phase intermediates between molecules and the elemental bulk. With stable zirconocene- and hafnocene-substituted derivatives, we here report the first examples containing directly bonded transition-metal fragments that are readily accessible from the ligato-lithiated Si siliconoid (1Li) and Cp MCl (M=Zr, Hf). Charge-neutral siliconoid ligands with pending tetrylene functionality were prepared by the reaction of amidinato chloro tetrylenes [PhC(NtBu) ]ECl (E=Si, Ge, Sn) with 1Li, thus confirming the principal compatibility of such low-valent functionalities with the unsaturated Si cluster scaffold. The pronounced donor properties of the tetrylene/siliconoid hybrids allow for their coordination to the Fe(CO) fragment.

Individuals' involvement in reactive and proactive online aggression has garnered widespread concern from various societal sectors, marking it as a critical indicator of individual social development. The influencing factors that might exist for both reactive and proactive online aggression have been little explored. Understanding these could help us develop more effective intervention strategies, targeting individuals who exhibit both types of aggression.

Purpose Of Review: The purpose of this narrative review is to describe the mechanisms for gut dysfunction during critical illness, outline hypotheses of gut-derived inflammation, and identify nutrition and non-nutritional therapies that have direct and indirect effects on preserving both epithelial barrier function and gut microbiota during critical illness.
Recent Findings: Clinical and animal model studies have demonstrated that critical illness pathophysiology and interventions breach epithelial barrier function and convert a normally commensal gut microbiome into a pathobiome. As a result, the gut has been postulated to be the "motor" of critical illness and numerous hypotheses have been put forward to explain how it contributes to systemic inflammation and drives multiple organ failure.

Word recognition is a fundamental reading skill that relies on various linguistic and cognitive abilities. While executive functions (EF) have gained attention for their importance in developing literacy skills, their interaction with domain-specific skills in facilitating reading among different learner groups remains understudied. This study examines the relationship between EF, orthographic awareness, morphological awareness, and Chinese word recognition in 204 Chinese as a second language (CSL) students and 419 native Chinese primary students.

: The utilization of maternal health services at the primary healthcare level is still considered an effective approach despite the critical role in improving maternal health outcomes. The study aimed to assess the influence of sociodemographic characteristics and interpersonal support on the use of maternal health services in three regions of the Province of Jambi, Indonesia. : Using a mixed-methods sequential explanatory design, a quantitative survey of 432 women and qualitative focus group discussions with nine families were conducted.
