Green Light Activated Dual-Action Pt(IV) Prodrug With Enhanced PDT activity.

Light induced release of cisplatin from Pt(IV) prodrugs is a promising tool for precise spatiotemporal control over the antiproliferative activity of Pt-based chemotherapeutic drugs. A combination of light-controlled chemotherapy (PACT) and photodynamic therapy (PDT) in one molecule has the potential to overcome crucial drawbacks of both Pt-based chemotherapy and PDT via a synergetic effect. Herein we report green-light-activated Pt(IV) prodrug GreenPt with BODIPY-based photosentitizer in the axial position with an incredible high light response and singlet oxygen generation ability.

Unsymmetric triazine-based triglucoside detergents for membrane protein stability.

Membrane proteins play a crucial role in a variety of biological processes and are key targets for pharmaceutical development. Structural studies of membrane proteins provide molecular insights into the mechanisms of these processes and are essential for effective drug discovery. Historically, these studies have relied on solubilization of the target protein using detergents, but conventional detergents often fail to maintain the stability of challenging membrane proteins.

Modular Photoswitchable Molecular Glues for Chemo-optogenetic Control of Protein Function in Living Cells.

Optogenetic systems using photosensitive proteins and chemically induced dimerization/proximity (CID/CIP) approaches enabled by chemical dimerizers (also termed molecular glues), are powerful tools to elucidate the dynamics of biological systems and to dissect complex biological regulatory networks. Here, we report a versatile chemo-optogenetic system using modular, photoswitchable molecular glues (sMGs) that can undergo repeated cycles of optical control to switch protein function on and off. We use molecular dynamics (MD) simulations to rationally design the sMGs and further expand their scope by incorporating different photoswitches, resulting in sMGs with customizable properties.

Nucleophilic Functionalization of a Cationic Pentaphosphole Complex - A Systematic Study of Reactivity.

The systematic nucleophilic functionalization of the cationic pentaphosphole ligand complex [Cp*Fe(η4-P5Me)][OTf] (A) with group 16/17 nucleophiles is reported. This method represents a highly reliable and versatile strategy for the design of novel transition-metal complexes featuring twofold substituted end-deck cyclo-P5 ligands, bearing unprecedented hetero-element substituents. By the reaction of A with classical group 16 nucleophiles, complexes of the type [Cp*Fe(η4-P5MeE)] (E = OEt (1), OtBu (2), SPh (3), SePh (4)) are obtained.

Enhancing Compliance With Preoperative Fasting Guidelines: A Closed-Loop Quality Improvement Initiative to Optimize Patient Safety and Outcomes.

Introduction Preoperative fasting is essential in surgical care to reduce the risk of pulmonary aspiration during anesthesia. International guidelines, such as those from the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA), recommend fasting durations of six hours for solids and two hours for clear liquids. However, adherence to these guidelines often varies in clinical practice, leading to prolonged fasting times that can negatively impact patient outcomes, including dehydration, hypoglycemia, discomfort, and delayed recovery.

Key elements for designing effective second victim support interventions: a focus group study in European clinical settings.

Background: The second victim (SV) experience limits the performance of health and care workers and places patients at risk. Peer support is recognised as the most effective, feasible and acceptable intervention to mitigate its impact.

Objective: To define a set of success factors when designing interventions to support SVs in health and care facilities based on expertise in different European countries.

Beyond the random phase approximation for calculating Curie temperatures inferromagnets: application to Fe, Ni, Co and monolayer CrI3.

The magnetic properties of solids are typically analyzed in terms of Heisenberg models where the electronic structure is approximated by interacting localized spins. However, even in such models the evaluation of thermodynamic properties constitutes a major challenge and is usually handled by a mean field decoupling scheme. The random phase approximation (RPA) comprises a common approach and is often applied to evaluate critical temperatures although it is well known that the method is only accurate well below the critical temperature.

Boosting the performance of a zero-gap flow microbial fuel cell by immobilized redox mediators.

Although microbial fuel cells (MFC) could be a promising energy source, their implementation is largely limited by low performance. There are several approaches to overcome this issue. For example, MFC performance can be enhanced using redox mediators (RM) capable of transferring electrons between microorganisms and MFC electrodes.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Short-term effects of follicle stimulating hormone on immune function, lipid, and vitamin metabolism in transiently castrated men.

Background: Prostate cancer therapy with surgical or chemical castration with GnRH agonists has been linked to elevated FSH levels, which may contribute to secondary health disorders, including atherosclerosis and diabetes. Although recent findings suggest a role for FSH beyond the reproductive system, its metabolic impact remains unclear and difficult to disentangle from that of androgens. In this study, we examined the metabolic changes induced by FSH and distinguished them from those caused by testosterone.

Cholecystectomy for acute cholecystitis during weekend compared with delayed weekday surgery: A nationwide population cohort study.

Background: The optimal timing of surgery for acute cholecystitis has been a subject of debate, but the predominant view supports early cholecystectomy. This study investigated the safety of early cholecystectomy during weekends compared with delayed surgery until a weekday.

Methods: This was a population-based cohort study based on data from the Swedish National Register for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks).

Exploring spiking neural networks for deep reinforcement learning in robotic tasks.

Spiking Neural Networks (SNNs) stand as the third generation of Artificial Neural Networks (ANNs), mirroring the functionality of the mammalian brain more closely than their predecessors. Their computational units, spiking neurons, characterized by Ordinary Differential Equations (ODEs), allow for dynamic system representation, with spikes serving as the medium for asynchronous communication among neurons. Due to their inherent ability to capture input dynamics, SNNs hold great promise for deep networks in Reinforcement Learning (RL) tasks.

Deep Eutectic Solvents as Electrolytes for Zn Batteries: Between Blocked Crystallization, Electrochemical Performance and Corrosion Issues.

Deep eutectic solvents (DESs) are an emerging class of ionic liquids with high tunability and promise for battery applications. In this study, we investigated acetamide-based DESs for Zn batteries, focusing on a synergistic mixture of two known acetamide (Ace)-based DESs: Ace4ZnCl2 and Ace4ZnTFSI2. By combining these two DESs in various ratios, we aimed to enhance ionic conductivity and optimize electrochemical performance while addressing corrosion concerns.

Neuropathological features of cerebrovascular diseases.

Optimal blood flow through a patent cerebral circulation is critical for supply of oxygen and nutrients for brain function. The integrity of vascular elements within arterial vessels of any calibre can be compromised by various disease processes. Pathological changes in the walls of veins and the venous system may also alter the dynamics of cerebral perfusion.

Perovskite CsCuClxBr3- x Microcrystals: Band Structure, Photochemical Stability, and Photocatalytic Properties.

Although Pb-based metal halide perovskites (MHPs) have excellent photoelectric characteristics, their toxicity remains a limiting factor for their widespread application. In the paper, a series of CsCuClxBr3-x (x = 1, 2, 3) MHP microcrystals were developed and their hydrogen evolution performance in ethanol and HX (X = Cl, Br) was also studied. Among them, CsCuCl3 microcrystals exhibit high hydrogen evolution performance in both HX and ethanol, attributed to their longest average lifetime and suitable band structure.

A Dynamic Metal-Organic Radical Emission System.

Developing new organic radical emission systems and regulating their luminescence properties presents a significant challenge. Herein, we build dynamic and multi-emission band radical luminescence systems by co-assembling inorganic metal salts with carbonyl compounds in ionic liquids. After the assembling, dual-band, and excitation wavelength-dependent emission was observed upon light irradiation, one emission band originates from carbonyl radical after light irradiation, the other band from the ligand-metal charge transfer (LMCT) state, which benefits from the charge transfer from the radicals to the metal salts.

Does dose matter? Parental attendance in a preventive intervention for anxious and sad children.

Background: International studies show increasing prevalence of anxiety and depression among children. Parents are vital for children in all aspects of life, also in supporting their offspring in promoting better mental health, life skills and reducing emotional difficulties. Therefore, involving parents in interventions aimed at preventing development of anxiety and depression is natural.

Mortality and cancer incidence in the UK glass reinforced plastics manufacturing industry: a cohort study.

Objectives: According to the International Agency for Research on Cancer, styrene is probably carcinogenic for lymphohaematopoietic neoplasms, with insufficient evidence for other cancer sites. We compared mortality and cancer incidence (for the first time) in a UK cohort occupationally exposed to high levels of styrene to that of the general population of England and Wales.

Methods: The follow-up for mortality ran from 1969 to 2022, while the follow-up for cancer incidence ran from 1971 to 2020.

Geographical differences in thrombolysis treatment for acute ischaemic stroke.

Background: Administering intravenous thrombolysis (IVT) as soon as possible after symptom onset impacts on the functional outcome for patients with acute ischaemic stroke. The study aimed to assess whether the distance from hospital impacts on the access to IVT for acute ischaemic stroke at the University Hospital of North Norway in Tromsø (UNN Tromsø).

Material And Method: This prospective quality study included 231 patients admitted with acute ischaemic stroke to UNN in the period 1 January 2019-31 December 2019.

The history of Jervell and Lange-Nielsen syndrome.

Background: First-time documentation of rare diseases is normally in the form of case reports. These are typically based on unexpected observations by vigilant clinicians and lead to further research on prevalence and aetiology. One of the best-known Norwegian examples is Jervell and Lange-Nielsen syndrome.

Cognitive and affective processes in children's third-party punishment.

This study investigated how children's punishment affective states change over time, as well as when children begin to prioritise intentions over outcomes in their punishment decisions. Whereas most prior research sampled children from Anglo-America or Northwestern Europe, we tested 5- to 11-year-old children from Colombia and Spain ( = 123). We focused on punishment behaviour in response to ostensibly real moral transgressions, rather than punishment recommendations for hypothetical moral transgressions.

The Water Framework Directive's protection of groundwater-dependent terrestrial ecosystems.

The Water Framework Directive protects groundwater-dependent terrestrial ecosystems, but its concepts and definitions remain unclear. This paper aims to clarify the margin of discretion for the Member States, by applying a cross-disciplinary legal and biological analysis. We conclude that description of the protected ecosystems must include at least key components and processes and be based on a number of well-known groundwater-dependent habitats, but not restricted to habitats fed entirely by groundwater.

Outcomes of Gallbladder Drainage Techniques in Acute Cholecystitis: Percutaneous Versus Endoscopic Methods.

Acute cholecystitis, often caused by gallstones obstructing the cystic duct, is a potentially life-threatening condition that requires timely intervention. High-risk patients, particularly those with significant comorbidities, may not be suitable candidates for laparoscopic cholecystectomy, necessitating alternative drainage techniques such as percutaneous cholecystostomy (PC) and endoscopic gallbladder drainage (EGD). This systematic review aims to compare the efficacy, safety, and outcomes of PC and EGD in managing acute cholecystitis in high-risk surgical patients.
