Nanoscopic Titanium Dioxide Overlayers Improve the Durability of Porphyrin Molecular Electrocatalysts while Maintaining Molecular Structure and Redox Activity.

Molecular catalysts, such as metalated porphyrins, are attractive cocatalysts for photocatalytic water splitting owing to their potential to simultaneously catalyze target reactions at their metal center, extend charge-separated-state lifetimes, and accumulate the requisite charge for product formation. However, porphyrin catalysts, like most molecular catalysts, are often limited by poor stability associated with demetalation, inactivation by undesired bonding (e.g.

Fitness and Morphology Support Genetic Differentiation Across Different Geographic Scales in a Native Insect Utilising Native vs. Invasive Host Plants.

Native species can evolve rapidly in response to utilising invasive species as novel resources. We investigated the genetic and trait differentiation of the Australian soapberry bug across three biotypes: those feeding on invasive in New South Wales (NSW) and Queensland (Qld), invasive in the Northern Territory (NT), and on the native host (in Qld). Genetic analyses revealed moderate differentiation between NT insects and those from NSW and Qld (  = 0.

Effect of revision sacroiliac joint fusion on unresolved pain and disability: a retrospective cohort study.

Purpose: The sacroiliac (SI) joint is recognized as a source of low back pain in 15-30% of patients. Though randomized controlled trials have shown clinical improvement following SI joint fusion in 83.1% of patients, revision rates of 2.

Stability and Dissociation of Adeno-Associated Viral Capsids by Variable Temperature-Charge Detection-Mass Spectrometry.

Adeno-associated viral (AAV) vectors have emerged as gene therapy and vaccine delivery systems. Differential scanning fluorimetry or differential scanning calorimetry is commonly used to measure the thermal stability of AAVs, but these global methods are unable to distinguish the stabilities of different AAV subpopulations in the same sample. To address this challenge, we combined charge detection-mass spectrometry (CD-MS) with a variable temperature (VT) electrospray source that controls the temperature of the solution prior to electrospray.

The Center-Center Technique for the Direct Anterior Approach in Total Hip Arthroplasty: Precise Femoral Canal Preparation to Optimize Implant Fit and Fill.

Background: The use of the direct anterior approach has been criticized as a significant risk factor for subsidence, perioperative fracture, and thigh pain. Therefore, the purpose of our study was to evaluate the outcome of using the center-center technique via the direct anterior approach.

Materials And Methods: Consecutive elective primary total hip arthroplasties performed using the center-center technique were retrospectively reviewed from May 2015 to February 2017.

Evaluation of Sex, Ethnic, and Racial Diversity Across US ACGME-Accredited Orthopedic Subspecialty Fellowship Programs.

In recent years, there has been an increasing trend toward subspecialization in orthopedic surgery via fellowships. This study sought to characterize sex, ethnic, and racial representation within each fellowship program and to examine their changes over time to identify trends and/or gaps. Demographic data were obtained from the National Graduate Medical Education Census.
