Flexural strength and mode of failure of interim implant-supported fixed dental prostheses following different conversion techniques and structural reinforcement.

Statement Of Problem: Challenges persist with conventional polymethyl methacrylate (PMMA) prosthetic materials and conversion protocols for immediate implant-supported interim restorations. Advances, such as the use of fiber-reinforced composites (FRCs), and novel conversion protocols, such as the Smart Denture Conversion (SDC), may mitigate existing prosthetic complications, yet their impact on flexural strength and mode of failure remains unclear.

Purpose: The purpose of this in vitro study was to better understand the effect of the conversion method and to characterize the relevance of reinforcing interim implant-supported fixed prosthetics with FRCs.

Understanding community resilience during the drinking water contamination event on Oahu, Hawaii, 2021-2022: a mixed mode approach.

Background: A petroleum leak into the Joint Base Pearl Harbor-Hickam water system on Oahu, Hawaii in November 2021 contaminated the drinking water of approximately 93,000 users, causing many to relocate for months. Perceptions of health and wellbeing were captured using the Centers for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR) Assessment of Chemical Exposures (ACE) cross-sectional survey in collaboration with the Hawaii Department of Health (HDOH).

Methods: Responses from the ACE online survey of community members, businesses, schools, health care and veterinary care organizations during the contamination event, containing quantitative questions and qualitative information from an open text field, were analyzed.

A Review of Climate-Driven Threats to Recreational Water Users in Hawaii.

In Hawaii, impacts from climate change, such as sea-level rise and flooding, increased hurricanes and wildfires, and warmer temperatures, intersect with aging infrastructure, toxicities from the built environment, and pathogens to threaten the health of recreational ocean users via reduced water quality, severe weather and flooding, environmental degradation, and food systems impacts. An examination of climate-driven threats to water safety is a pertinent review of threats to coastal residents globally.

Formation of Uranyl Peroxide Compounds via Dissolution of Studtite, [(UO)(O)(HO)](HO), in Ionic Liquids.

Four uranyl peroxide compounds with novel structures were formed following the dissolution of studtite, [(UO)(O)(HO)](HO), in imidazolium-based ionic liquids. The compounds were characterized using single crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD), Raman and infrared (IR) spectroscopy, and scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS). The ionic liquids used in the experiments were 1-ethyl-3-methylimidazolium (EMIm) diethyl phosphate, EMIm ethyl sulfate, and EMIm acetate.

Evaluation of adherence of Candida albicans to differently manufactured acrylic resin denture base materials.

Statement Of Problem: Though computer-aided design and computer-aided manufactured (CAD-CAM) denture bases have become popular, evidence on the ability of C. albicans cells to adhere to these denture bases is lacking.

Purpose: The purpose of this in vitro study was to evaluate the adherence of Candida albicans to differently manufactured acrylic resin denture bases.

A New Molybdenum Blue Structure Type: How Uranium Expands this Family of Polyoxometalates.

The assembly of molybdenum polyoxometalates (POMs) has afforded large discrete nanoclusters with varied degrees of reduction such as the ~20 % reduced molybdenum blues. While many heterometals have been incorporated into these clusters to afford new properties, uranium has yet to be reported. Here we report the first uranium containing molybdenum blue clusters and the unique properties exhibited by this incorporation.

Study design and methods: U.S. study to protect brain health through lifestyle intervention to reduce risk (U.S. POINTER).

Introduction: The U.S. study to protect brain health through lifestyle intervention to reduce risk (U.

Evaluation of surface roughness of differently manufactured denture base materials.

Statement Of Problem: The popularity of computer-aided design and computer-aided manufacturing (CAD-CAM) dentures has led to the introduction of new denture materials and resins. However, studies on the surface characteristics of these materials and how they compare to dentures fabricated by more traditional methods are lacking.

Purpose: The purpose of this cross-sectional study was to determine whether the surface roughness (Ra) of denture base materials differed based on manufacturing technique.

Community health impacts after a jet fuel leak contaminated a drinking water system: Oahu, Hawaii, November 2021.

Background: In 2021, a large petroleum leak contaminated a water source that supplied drinking water to military and civilians in Oahu, Hawaii.

Methods: We conducted an Assessment of Chemical Exposures (ACE) survey and supplemented that information with complementary data sources: (1) poison center caller records; (2) emergency department visit data; and (3) a key informant questionnaire.

Results: Among 2,289 survey participants, 86% reported ≥1 new or worsening symptom, 75% of which lasted ≥30 days, and 37% sought medical care.

Targeting Diverse Bridging Motifs within Actinide Borosulfates and Establishing an Unconventional Structural Hierarchy.

The first actinide borosulfates, (UO)[B(SO)(SOOH)] (TSUBOS-1) and (UO)[BO(SO)(SOOH)] (TSUBOB-1), were synthesized solvothermally in oleum using UO. The classical borosulfate crystal structure of TSUBOS-1 is partially consistent with an established conventional hierarchy. Uranyl pentagonal bipyramids limit the anionic network linkages and isolate sulfate tetrahedra within the anionic network.

Ambient sampling of real-world residential wood combustion plumes.

Wood smoke contains large quantities of carbonaceous aerosols known to increase climate forcing and be detrimental to human health. This paper reports the findings from our ambient sampling of fresh residential wood combustion (RWC) plumes in two heating seasons (2015-2016, 2016-2017) in Upstate New York. An Aethalometer (AE33) and a pDR-1500 were employed to monitor residential wood smoke plumes in Ithaca, NY through a hybrid mobile-stationary method.

Radiation-Induced Solid-State Transformations of Uranyl Peroxides.

Single-crystal X-ray diffraction studies of pristine and γ-irradiated Ca[UO(O)]·9HO reveal site-specific atomic-scale changes during the solid-state progression from a crystalline to X-ray amorphous state with increasing dose. Following γ-irradiation to 1, 1.5, and 2 MGy, the peroxide group not bonded to Ca is progressively replaced by two hydroxyl groups separated by 2.

Appropriateness of antibiotic selection for pneumonia in the emergency department: pre- and post-order set changes.

Objectives: Emergency department (ED) providers face pressure to meet sepsis mandates such as prompt administration of antibiotic therapy, which can lead to the overuse of broad-spectrum antibiotics. In recent years, there has also been a push to adhere to institutional antibiotic stewardship goals including decreasing inappropriate antibiotic therapy and limiting duration of therapy. Previous literature has demonstrated that the incorporation of clinical decision support (CDS) tools in electronic medical records can aid in guiding appropriate antibiotic prescribing.

deca-rbonylation of ,-di-methyl-formamide to form di-methyl-ammonium cations in the hybrid framework compound {[(CH)NH][Zn{OPCH(OH)PO}]} .

The title phospho-nate-based organic-inorganic hybrid framework, poly[bis(dimethylammonium) [(μ-2,5-dihydroxybenzene-1,4-diphosphonato)zinc(II)]], {(CHN)[Zn(CHOP)]} , was formed unexpectedly when di-methyl-ammonium cations were formed from the deca-rbonylation of the ,-di-methyl-formamide solvent. The framework is built up from ZnO tetra-hedra and bridging di-phospho-nate tetra-anions to generate a three-dimensional network comprising [100] channels occupied by the (CH)NH cations. Within the channels, an array of N-H⋯O hydrogen bonds help to establish the structure.
