Acid-Enhanced Photoiniferter Polymerization under Visible Light.

Photoiniferter (PI) is a promising polymerization methodology, often used to overcome restrictions posed by thermal reversible addition-fragmentation chain-transfer (RAFT)  polymerization. However, in the overwhelming majority of reports, high energy UV irradiation is required to effectively trigger photolysis of RAFT agents and facilitate the polymerization, significantly limiting its potential, scope, and applicability. Although visible light PI has emerged as a highly attractive alternative, most current approaches are limited to the synthesis of lower molecular weight polymers, and typically suffer from prolonged reaction times, extended induction periods, and higher dispersities.

Propagation of Orientation Across Lengthscales in Sheared Self-Assembling Hierarchical Suspensions via Rheo-PLI-SAXS.

Simultaneous rheological, polarized light imaging, and small-angle X-ray scattering experiments (Rheo-PLI-SAXS) are developed, thereby providing unprecedented level of insight into the multiscale orientation of hierarchical systems in simple shear. Notably, it is observed that mesoscale alignment in the flow direction does not develop simultaneously across nano-micro lengthscales in sheared suspensions of rod-like chiral-nematic (meso) phase forming cellulose nanocrystals. Rather, with increasing shear rate, orientation is observed first at mesoscale and then extends to the nanoscale, with influencing factors being the aggregation state of the hierarchy and concentration.

Pros and cons of sub-specialisation in orthopaedics and traumatology-Is the general orthopaedic and trauma surgeon a relic of the past?

The evolution of orthopaedics has witnessed a pronounced shift from generalist practice to subspecialisation, a trend that has fundamentally reshaped the field over the past century. Originally, orthopaedic surgeons were trained to address a broad spectrum of musculoskeletal conditions. However, increasing complexity and specialization in knowledge have driven a progressive narrowing of focus within orthopaedics.

Objectives: The purpose of this study was to quantify the prevalence of cardiovascular involvement in TB patients and investigate changes after completion of anti-TB treatment.

Characteristics and Effectiveness of XP-Endo Files and Systems: A Narrative Review.

XP-endo files are composed of Max-Wire alloy, which was developed by FKG Dentaire (La Chaux-de-Fonds, Switzerland). This alloy, known as Martensite-Austenite Electropolish Flex, is the first NiTi alloy used in endodontics to combine the shape memory effect with superelasticity for use in clinical practice. This article aims to provide a comprehensive overview of the existing knowledge and evidence regarding different XP-endo files and systems, XP-endo Finisher (XPEF), XP-endo Shaper (XPES), XP-endo Retreatment (XPER), XP-endo Rise (XPE-Rise), and XPE-Rise Retreatment (XPE-Rise-R), to help clinicians understand their different properties and recommended clinical uses.

Spns1-dependent endocardial lysosomal function drives valve morphogenesis through Notch1-signaling.

Autophagy-lysosomal degradation is a conserved homeostatic process considered to be crucial for cardiac morphogenesis. However, both its cell specificity and functional role during heart development remain unclear. Here, we introduced zebrafish models to visualize autophagic vesicles and track their temporal and cellular localization in the larval heart.

Aim: Aiming to offer a diagnostic tool to aid examiners with correct hip typing and decision-making about patient management, members of the Board of the International Interdisciplinary Consensus Committee on DDH Evaluation (ICODE - https://www.icode.expert), introduced the cross-platform mobile application (Android and iOS) called "ICODE Hip US Calculator".

Advancing high-resolution musculoskeletal ultrasound: a histology- and anatomy-driven approach for enhanced shoulder imaging. Part 2: Anterior and lateral shoulder.

Ultrasonography is a reliable imaging technique for the accurate diagnosis and evaluation of musculoskeletal disorders. Recent developments in ultrasound technology have significantly increased image resolution, making it possible to see anatomical features at almost microscopic dimensions. Current standards for standardized shoulder ultrasonography mostly depend on outdated machine types and configurations that may not fully utilize these high-resolution imaging capabilities.

Case report: Discovery of tuberculosis caused by in free-ranging vervet monkeys in the Greater Kruger Conservation Area.

Animal tuberculosis (TB) has been reported in several wildlife species in the Greater Kruger Conservation Area (GKCA), South Africa. This report describes the discovery of clinical tuberculosis, caused by (), in free-ranging vervet monkeys (). The "One Health" concept is especially relevant to TB since this is a multi-host disease with zoonotic potential and is endemic in GKCA.

Gracilis flap and partial colpocleisis of Kahr for pelvic organ prolapse after anterior exenteration: A case report.

Anterior exenteration is a radical surgical option for treating locally advanced pelvic malignancies when alternative treatments are deemed ineffective or inappropriate. Due to its nature as an ablative treatment, interference with supportive structures of the pelvic floor can result in pelvic organ prolapse. A 70-year-old woman presented with prolapse after radical cystectomy and following two unsuccessful attempts at Le Fort colpocleisis, the second of which was further complicated by rupture of the vaginal cuff.

Arterio-Ureteral Fistula as a Long-term Complication Following Retroperitoneal Presacral Ganglioneuroma Resection: Case Report in an Adolescent and Review of the Literature.

Arterio-ureteral fistula (AUF) is a rare condition affecting nearby adult-only patients. Patients usually present with hematuria, often starting as intermittent hematuria which frequently increases, and may lead to hemorrhagic shock. Without rapid diagnosis and prompt treatment, AUF can be lethal.

Iodine Activation from Iodate Reduction in Aqueous Films via Photocatalyzed and Dark Reactions.

Iodine in the atmosphere destroys ozone and can nucleate particles by formation of iodic acid, HIO. Recent field observations suggest iodate recycles from particles sustaining significant gas-phase IO radical concentrations (0.06 pptv) in aged stratospheric air, and in elevated dust plumes.

Indirect effects of the COVID-19 pandemic: A cause-of-death analysis of life expectancy changes in 24 countries, 2015 to 2022.

Worldwide, mortality was strongly affected by the COVID-19 pandemic, both directly through COVID-19 deaths and indirectly through changes in other causes of death. Here, we examine the impact of the pandemic on COVID-19 and non-COVID-19 mortality in 24 countries: Australia, Austria, Brazil, Bulgaria, Canada, Chile, Croatia, Czechia, Denmark, England and Wales, Hungary, Japan, Latvia, Lithuania, The Netherlands, Northern Ireland, Poland, Russia, Scotland, South Korea, Spain, Sweden, Switzerland, and the United States. Using demographic decomposition methods, we compare age- and cause-specific contributions to changes in female and male life expectancy at birth in 2019-2020, 2020-2021, and 2021-2022 with those before the COVID-19 pandemic (2015-2019).

Dynamic response to short-pulsed U-ion beams of material candidates for vacuum beam windows manufacturing.

The introduction of next-generation extremely energetic particle accelerator facilities, such as the High-Luminosity upgrade of the LHC (HL-LHC) or the proposed future circular collider (FCC), will dramatically increase the energy stored in the circulating particle beams. This will critically affect the thermo-physical and mechanical properties of the materials adopted, possibly compromising their reliability during the operating lifetime. In this scenario, it is paramount to assess the dynamic thermo-mechanical response of materials presently used, or being developed for future use, in beam intercepting devices exposed to potentially destructive events caused by the impact of energetic particle beams.
