Summary: Magnetic drug delivery is an efficient method to transport drugs directly to organs or targeted locations in the body. The study examines the Cu-BTC (HKUST-1) MOF as a drug carrier through optimized crystalline growth and structural properties. The results suggest that this drug delivery technique using bio-compatible MOFs is effective.

Summary: A model of strain accumulation in nitrogen implanted polycrystalline tungsten films is proposed. The study shows that the strain saturation and phase transition to fcc beta-W2N occur after a certain fluence. The strain distribution of fcc beta-W2N formed at higher fluences varies differently.

Summary: The reactions of the [MnIII(TMPP)(SO3CF3)] complex with an excess of DMAP and HMTA were examined, resulting in the formation of complexes I and II, respectively. The electronic spectra of I and II indicate high-spin Mn(III) metalloporphyrins. Cyclic voltammetry investigation was conducted on both complexes. The crystal structures of I and II were determined by X-ray diffraction and their bioactivity was assessed in vitro.

Summary: An extensive understanding of the bulk crystalline structures of WO3 and WSe2, as well as the solvent effects on their surfaces, is crucial for designing efficient (photo) electrocatalysts. However, there is a lack of knowledge about the atomistic level understanding of these materials and the solvation processes on their surfaces. In this study, Density Functional Theory-based molecular dynamics simulations were used to assess the role of explicit water environment in characterizing solid surfaces. The results demonstrate the importance of considering liquid water and its dynamics in assessing catalytic features.

Summary: Hydroxyl radical protein footprinting is a method to assess protein structure in the solution state using synchrotron radiation. It involves generating hydroxyl radicals through X-ray radiolysis of water, which react with protein side chains and can be detected using mass spectrometry. The optimization of hydroxyl radical dose is typically done using a fluorescence assay, but a direct evaluation of labeling using intact mass spectrometry can provide more accurate and immediate feedback. This method allows for absolute and direct dosimetry for all types of protein footprinting.

Summary: A high loading of high-density and high-atomic-number fillers in radiation shields is necessary for desirable X-ray attenuation characteristics. However, this high loading severely impairs the mechanical and viscoelastic properties of polymers, poses a long-term threat to the mechanical integrity and radiation protection, and may increase the shield temperature after prolonged exposure to ionizing radiation. Inadequate thermal conduction can also make the user uncomfortable. This study developed SBS-tungsten composites and found that the concentration of styrene in the SBS and W loading significantly affected the attenuation, mechanical and rheological properties, and thermal conductivity of the composites.

Summary: The study revealed that the tungsten surface layer after helium implantation is composed of compressed, transition, expanded, and matrix zones. The compressed zone became thinner after helium implantation possibly due to the formation of He-complexes, while the expanded zone resulted from helium atoms entering the tungsten lattice. The transition zone is a result of competition between the expanding and compressing effects.

Summary: The reaction of Tp*(WI)-I-II(CO)(2) with (R)-( + )-alpha-methylbenzylamine in dichloromethane produces blue, diamagnetic Tp*W-II(R)-(+)-LHI(CO)(2). This complex features a six-coordinate, distorted-octahedral structure and is unusually stable and resistant to oxygen- and sulfuratom transfer reactions.

Summary: The functionalization process of amorphous Ge25Se55Te20 chalcogenide thin films with three organosilanes has been studied by X-ray photoelectron spectrometry. The study reveals the formation of new oxidized environments after functionalization, indicating the covalent anchorage of organosilane precursors through the formation of Te-O-Si groups.

Summary: This paper discusses emission lines from ground state transitions of He- and H-like argon ions with n=2 levels, as well as X-ray transitions from common elements in tokamaks. By comparing with atomic structure calculations, X-ray transitions from tungsten, molybdenum, iron, and sulfur in the wavelength range of 3700-4000 m angstrom are identified. Individual lines from tungsten charge states near Zn-like W44+ and B-like Mo37+ are documented, and the behavior of line ratios with electron temperature is examined to support the identifications.

Summary: Operative times for lower extremity orthopedic trauma increased as resident seniority increased. Senior resident participation was associated with increased wound dehiscence, whereas junior resident participation was associated with an increased risk of deep surgical site infections. Academic quarter within the academic year did not correlate with any of the surgical complications.

Summary: The clinical practice guideline focuses on the treatment of severe lower limb trauma and provides evidence-based recommendations for key decisions on limb salvage versus early amputation. There are 11 recommendations in the guideline to evaluate important decision factors. The work group also emphasized the need for further research on the treatment of high-energy lower extremity trauma and the shared decision-making process.

Summary: Tourniquets are critically important for controlling traumatic extremity hemorrhage. This study investigated the effects of prolonged tourniquet application and delayed limb amputation on survival, systemic inflammation, and remote organ injury. The results showed that prolonged tourniquet application and delayed limb amputation increased the risk of complications, including systemic inflammation and dysfunction of remote organs. Improved strategies are needed to mitigate these systemic effects, especially in military settings. Additionally, further research is necessary to extend the time window for evaluating limb viability after tourniquet deflation and develop new point of care tests to assess the risks of tourniquet deflation for limb preservation and patient care optimization.

Summary: Patients with combat-related lower extremity amputations experience a rapid decline in bone mineral density in both amputated and intact limbs, stabilizing after approximately 3 years, with an average loss of 100 HU after 1,000 days. Other factors affecting bone mineral density include ambulatory status, age, surgical complications, level of amputation, and vitamin-D treatment.

Summary: The aim of this study was to develop a data-driven approach for identifying limb salvage cases and studying their clinical outcomes. With the use of medical code data, a population of 2018 US Service members who underwent limb salvage was identified, representing 59.5% of the combat-related lower extremity trauma population. Comparison with expert opinion showed moderate agreement, and the approach demonstrated potential for future retrospective analyses of short- and long-term outcomes.

Summary: This study aimed to develop and characterize a closed intra-articular fracture (IAF) mediated post-traumatic osteoarthritis (PTOA) model in rats to serve as a testbed for putative disease modifying interventions. The results showed that a high-energy (5 J) blunt-force impact effectively induced intra-articular fractures in rats and resulted in typical osteoarthritic changes at 56 days, suggesting that this model can provide a reliable testbed for screening disease modifying interventions for high-energy joint injuries.
