Gold(I)-Catalyzed 2-Deoxy-β-glycosylation via 1,2-Alkyl/Arylthio Migration: Synthesis of Velutinoside A Pentasaccharide.

2-Deoxy-β-glycosides are essential components of natural products and pharmaceuticals; however, the corresponding 2-deoxy-β-glycosidic bonds are challenging to chemically construct. Herein, we describe an efficient catalytic protocol for synthesizing 2-deoxy-β-glycosides via either IPrAuNTf-catalyzed activation of a unique 1,2--positioned C2--propargyl xanthate (OSPX) leaving group or (PhO)PAuNTf-catalyzed activation of a 1,2--C2--alkynylbenzoate (OABz) substituent of the corresponding thioglycosides. These activation processes trigger 1,2-alkyl/arylthio-migration glycosylation, enabling the synthesis of structurally diverse 2-deoxy-β-glycosides under mild reaction conditions.

Case management in emergency care: impact evaluation of the CARED Program.

Background: Hospitals face mounting pressure to reduce unplanned utilization amid rising healthcare demands from an aging population. The Case management for At-Risk patients in the Emergency Department (CARED) program is among the first ED transitional care strategies to focus on both frail older adults and emergency department (ED) re-attenders to reduce acute hospital utilization. This study aims to evaluate the effectiveness of the CARED program in reducing hospital (re)admissions and ED re-attendances within 30- and 60 days post-discharge.

Safety and efficacy of minimally invasive associating liver partition and portal vein ligation for staged hepatectomy (ALPPS): a systematic review and meta-analysis.

Background: Liver malignancies present substantial challenges to surgeons due to the extensive hepatic resections required, frequently resulting in posthepatectomy liver failure. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was designed to increase the resectable liver volume, yet it is associated with significant mortality and morbidity rates. Recently, minimally invasive techniques have been incorporated into ALPPS, with the potential to improve the procedure's safety profile whilst maintaining efficacy.

Germanium nanocrystal non-volatile memory devices: fabrication, charge storage mechanism and characterization.

The widespread proliferation and increasing use of portable electronic devices and wearables, and the recent developments in artificial intelligence and internet-of-things, have fuelled the need for high-density and low-voltage non-volatile memory devices. Nanocrystal memory, an emergent non-volatile memory (NVM) device that makes use of the Coulomb blockade effect, can potentially result in the scaling of the tunnel dielectric layer to a very small thickness. Since the nanocrystals are electrically isolated, potential charge leakage paths localized defects in the thin tunnel dielectric can be substantially reduced, unlike that in a continuous polysilicon floating gate structure.

Assessment of hemodynamic disturbances and impaired ventricular filling in asymptomatic fontan patients: A 4D flow CMR study.

Background: The Fontan procedure is a surgical intervention designed for patients with single ventricle physiology, wherein the systemic venous return is redirected into the pulmonary circulation, thereby facilitating passive pulmonary blood flow without the assistance of ventricular propulsion. Consequently, long-term follow-up of individuals who have undergone the asymptomatic Fontan procedure is essential.

Objectives: The aims of this investigation were to: 1) examine the impact of flow components and kinetic energy (KE) parameters on hemodynamic disturbances in asymptomatic Fontan patients and control group; 2) Assess left ventricular diastolic dysfunction through the analysis of 4D flow parameters across different Fontan sub-groups; 3) Compare intracardiac flow parameters among Fontan sub-groups based on morphological features of the left ventricle (LV) and right ventricle (RV).

Microbial biopesticides: A one health perspective on benefits and risks.

Controlling insect pests that destroy crop and spread diseases will become increasingly crucial for addressing the food demands of a growing global population and the expansion of vector-borne diseases. A key challenge is the development of a balanced approach for sustainable food production and disease control in 2050 and beyond. Microbial biopesticides, derived from bacteria, viruses, fungi, protozoa, or nematodes, offer potentially significant benefits for promoting One Health and contributing to several United Nations Sustainable Development Goals (SDGs).

A qualitative study on general practitioners' perspectives on late-life depression in Singapore-part II: system- and physician-related factors.

Background: Little is known about the practices and resources employed by general practitioners (GPs) in Singapore to manage late-life depression.

Physician and patient perceptions of treatment were captured via cross-sectional surveys; patients' clinical characteristics were recorded by retrospective review of medical records.

Once a day administration of R(+) propranolol is sufficient to block vasculogenesis in a xenograft model of infantile hemangioma.

Objectives: Infantile hemangioma (IH) is a benign vascular tumor that occurs in 5% of infants, predominantly in female and preterm neonates. Propranolol is the mainstay of treatment for IH. Given the short half-life of propranolol regarding β-adrenergic receptor inhibition as well as its side effects, propranolol is administered to infants 2-3 times daily with 1 mg/kg/dose.

Behavior, mechanisms, and applications of low-concentration CO in energy media.

This review explores the behavior of low-concentration CO (LCC) in various energy media, such as solid adsorbents, liquid absorbents, and catalytic surfaces. It delves into the mechanisms of diffusion, adsorption, and catalytic reactions, while analyzing the potential applications and challenges of these properties in technologies like air separation, compressed gas energy storage, and CO catalytic conversion. Given the current lack of comprehensive analyses, especially those encompassing multiscale studies of LCC behavior, this review aims to provide a theoretical foundation and data support for optimizing CO capture, storage, and conversion technologies, as well as guidance for the development and application of new materials.

Measuring physical activity, automaticity and memory are determinants for physical activity promotion among physical therapists in cardiac and pulmonary rehabilitation: a cross-sectional survey.

Purpose: The study aims to identify determinants of implementation behavior among physical therapists frequently promoting physical activity (PA) in cardiac and pulmonary rehabilitation.

Methods: A cross-sectional online survey incorporating the Determinants of Implementation Behavior Questionnaire (DIBQ) and anchored by the Theoretical Domains Framework (TDF) was sent to physical therapists working in cardiac and pulmonary rehabilitation practices in Australia and Singapore. All items on the DIBQ were scored on a 7-point Likert scale from "Strongly Disagree" to "Strongly Agree.

Surface-Confined Disordered Hydrogen Bonds Enable Efficient Lithium Transport in All-Solid-State PEO-Based Lithium Battery.

Polyethylene oxide (PEO)-based electrolytes are essential to advance all-solid-state lithium batteries (ASSLBs) with high safety/energy density due to their inherent flexibility and scalability. However, the inefficient Li+ transport in PEO often leads to poor rate performance and diminished stability of the ASSLBs. The regulation of intermolecular H-bonds is regarded as one of the most effective approaches to enable efficient Li+ transport, while the practical performances are hindered by the electrochemical instability of free H-bond donors and the constrained mobility of highly ordered H-bonding structures.

Cycloolefin Copolymers With a Multiply Rigid Structure for Protecting Triplet Exciton From Thermo- and Moisture-Quenching.

Polymeric room temperature phosphorescence (RTP) materials have been well developed and utilized in various fields. However, their fast thermo- and moisture-quenching behavior highly limit their applications in certain harsh environments. Therefore, the preparation of materials with thermo- and moisture-resistant phosphorescence is greatly attractive.
