Dual-Energy Computed Tomography and Beyond: Musculoskeletal System.

Traditional monoenergetic computed tomography (CT) scans in musculoskeletal imaging provide excellent detail of bones but are limited in the evaluation of soft tissues. Dual-energy CT (DECT) overcomes many of the traditional limitations of CT and offers anatomical details previously seen only on MR imaging. In addition, DECT has benefits in the evaluation and characterization of arthropathies, bone marrow edema, and collagen applications in the evaluation of tendons, ligaments, and vertebral discs.

Comparison of Outcomes of Enoxaparin Bridge Therapy in HeartMate II versus HeartWare HVAD Recipients.

Background: There is a lack of robust data evaluating outcomes of enoxaparin "bridge" therapy in left ventricular assist device (LVAD) patients.

Methods: We performed a retrospective study of HeartMate II (HM II) and HeartWare HVAD recipients that received therapeutic enoxaparin as "bridge" therapy to describe bleeding and thrombotic events and compare outcomes between devices. The primary endpoint was the incidence of bleeding within 30 days of "bridge" episode.

Mendelian randomization provides no evidence for a causal role in the bidirectional relationship between depression and multiple sclerosis.

Background: Major depressive disorder (MDD) is common in multiple sclerosis (MS) and its incidence rises before MS diagnosis. However, the causality and direction of this association remain unclear.

Objective: The objective is to investigate the bidirectional relationship between MS and MDD using Mendelian randomization (MR).

Molecular Evolution of the Glutathione S-Transferase Family in the Bemisia tabaci Species Complex.

The glutathione S-transferase (GST) family plays an important role in the adaptation of herbivorous insects to new host plants and other environmental constrains. The family codes for enzymes that neutralize reactive oxygen species and phytotoxins through the conjugation of reduced glutathione. Here, we studied the molecular evolution of the GST family in Bemisia tabaci, a complex of >35 sibling species, differing in their geographic and host ranges.

Sedation Requirements in Patients on Venovenous or Venoarterial Extracorporeal Membrane Oxygenation.

Dalbavancin Use in the Emergency Department Setting.

Although dalbavancin's (DBV's) long half-life and one-time dosing strategy confer ideal administration in the ambulatory setting, the optimal role of DBV in the management of acute bacterial skin and skin structure infections (ABSSSIs) remains to be elucidated. The primary objective of this study was to compare treatment outcomes of ABSSSI between patients who received DBV in the emergency department (ED) as part of standard care versus patients who received DBV as part of a telehealth program. This was a retrospective cohort study evaluating patients who received DBV at 3 urban EDs.

Insight into the microbial world of Bemisia tabaci cryptic species complex and its relationships with its host.

The 37 currently recognized Bemisia tabaci cryptic species are economically important species and contain both primary and secondary endosymbionts, but their diversity has never been mapped systematically across the group. To achieve this, PacBio sequencing of full-length bacterial 16S rRNA gene amplicons was carried out on 21 globally collected species in the B. tabaci complex, and two samples from B.

Effect of excipient properties, water activity, and water content on the disproportionation of a pharmaceutical salt.

Excipients are crucial components of most pharmaceutical formulations. In the case of a solid oral dosage formulation containing the salt form of a weakly ionizable drug, excipient selection is critical, as some excipients are known to cause salt disproportionation (conversion of salt to the free form). Therefore, robust formulation design necessitates an in-depth understanding of the factors impacting salt disproportionation during processing or storage as this can negatively impact product quality and performance.

African ancestry of New World, Bemisia tabaci-whitefly species.

Bemisia tabaci whitefly species are some of the world's most devastating agricultural pests and plant-virus disease vectors. Elucidation of the phylogenetic relationships in the group is the basis for understanding their evolution, biogeography, gene-functions and development of novel control technologies. We report here the discovery of five new Sub-Saharan Africa (SSA) B.

Impact of Solid-State Form on the Disproportionation of Miconazole Mesylate.

Approximately 50% of solid oral dosage forms utilize salt forms of the active pharmaceutical ingredient (API). A major challenge with the salt form is its tendency to disproportionate to produce the un-ionized API form, decreasing the solubility and negatively impacting product stability. However, many of the factors dictating the tendency of a given salt to undergo disproportionation remain to be elucidated.

The discovery and investigation of a crystalline solid solution of an active pharmaceutical ingredient.

Understanding the phase behavior of crystal forms is essential in drug formulation development, as physical stability of the active pharmaceutical ingredient (API) is critical to achieving the desired bioavailability. Solvents greatly impact the physical stability of crystalline solids, resulting in a variety of well-known phase transitions, such as hydrate/solvate formation. However, solvent incorporation may also result in the formation of a less-known crystalline solid solutions (CSSs).

Long-term sustainable dendritic cell-specific depletion murine model for periodontitis research.

Dendritic cells (DCs) are specialized antigen-presenting cells that play a pivotal role in the pathogenesis of periodontitis. The use of animal models to study the role of DCs in periodontitis has been limited by lack of a method for sustained depletion of DCs. Hence, the objectives of this study were to validate the zDC-DTR knockin mouse model of conventional DCs (cDCs) depletion, as well as to investigate whether this depletion could be sustained long enough to induce alveolar bone loss in this model.

Identification and evaluation of suitable reference genes for gene expression studies in the whitefly Bemisia tabaci (Asia I) by reverse transcription quantitative realtime PCR.

This study presents a reliable method for performing reverse transcription quantitative realtime PCR (RT-qPCR) to measure gene expression in the whitefly Bemisia tabaci (Asia I) (Gennadius) (Hemiptera: Aleyrodidae), utilising suitable reference genes for data normalisation. We identified orthologs of commonly used reference genes (actin (ACT), cyclophilin 1 (CYP1), elongation factor 1α (EF1A), glyceraldehyde 3-phosphate dehydrogenase (GAPDH), ribosomal protein L13a (RPL13A), and α-tubulin (TUB1A)), measured the levels of their transcripts by RT-qPCR during development and in response to thermal stress, and evaluated their suitability as endogenous controls using geNorm, BestKeeper, and NormFinder programs. Overall, TUB1A, RPL13A, and CYP1 were the most stable reference genes during B.

Oxidized-phospholipids in reconstituted high density lipoprotein particles affect structure and function of recombinant paraoxonase 1.

Paraoxonase 1 (PON1) is an HDL-associated enzyme and exhibits anti-inflammatory, anti-diabetic, and anti-atherogenic properties. Association of PON1 to HDL particles increases the stability and activity of PON1 and is important for the normal functioning of the enzyme. HDL particles are made up of lipid and protein constituents and apolipoprotein A-I (apoA-I) is a principal protein constituent of HDL that facilitates various biological activities of HDL.

Oxidized phospholipid content destabilizes the structure of reconstituted high density lipoprotein particles and changes their function.

High density lipoprotein (HDL) particles are made up of lipid and protein constituents and apolipoprotein A-I (apoA-I) is a principal protein component that facilitates various biological activities of HDL particles. Increase in Ox-PL content of HDL particles makes them 'dysfunctional' and such modified HDL particles not only lose their athero-protective properties but also acquire pro-atherogenic and pro-inflammatory functions. The details of Ox-PL-induced alteration in the molecular properties of HDL particles are not clear.
