The SCP2 (sterol carrier protein 2)-thiolase (type-1) functions in the vertebrate peroxisomal, bile acid synthesis pathway, converting 24-keto-THC-CoA and CoA into choloyl-CoA and propionyl-CoA. This conversion concerns the β-oxidation chain shortening of the steroid fatty acyl-moiety of 24-keto-THC-CoA. This class of dimeric thiolases has previously been poorly characterized.

Background: Although education is critical to the mission of academic medical centers in the United States, it is often not quantified and monetized as are their research and clinical missions. We undertook this survey to assess the perceived valuation of educational endeavors of plastic surgeon faculty at the U.S.

Background: Integrated plastic surgery residency applicants sometimes complete research fellowships before residency. The average productivity and the impact of these fellowships on subsequent application to residency are unknown. The purpose of this study was to provide objective data to better understand the utility and productivity of a research fellowship.

Catechol oxidases and tyrosinases are coupled binuclear copper enzymes that oxidize various o-diphenolic compounds to corresponding o-quinones. Tyrosinases have an additional monooxygenation ability to hydroxylate monophenol to o-diphenol. It is still not clear what causes the difference in the catalytic activities.

Combining the star-shaped alkynyl ligands with low-nuclearity gold-copper triphosphane clusters produces 3D metallocage aggregates, which demonstrate room temperature phosphorescence in solution (max Φ =0.6). Their luminescence mainly originates from cluster-localized metal-to-ligand charge transfer excited state.

Lack of physician familiarity with alternative pain control strategies is a major reason why opioids remain the most commonly used first-line treatment for pain after surgery. This is perhaps most problematic in abdominal wall reconstruction, where opioids may delay ambulation and return of bowel function, while negatively affecting mental status. In this article, we discuss multimodal strategies for optimal pain control in abdominal wall reconstruction.

Optimal skin and soft tissue management in complex open abdominal wall reconstruction is an integral element of the operation to achieve optimal outcomes. Failure to provide stable, well-vascularized soft tissue coverage over the hernia repair can jeopardize the reconstruction through association with nonhealing wounds, mesh exposure, and even possible hernia recurrence. The literature has shown that careful attention to the skin and soft tissue, especially when part of a multidisciplinary approach to complex abdominal wall reconstruction, improves patient outcomes significantly.

It is inherently challenging to achieve successful surgical outcomes for ventral hernia repairs. For complex ventral hernias, attempts to reconstruct the abdomen in patients who are overweight, deconditioned, malnourished, chronically infected or inflamed, have previous hernia recurrence, or otherwise carry a number of serious comorbidities affecting their surgical fitness are a major undertaking requiring careful preparation and planning. As the rate of abdominal wall reconstructions rises, so does the complexity of these procedures.

Background: In 2014, the Accreditation Council for Graduate Medical Education (ACGME) increased the minimum required aesthetic surgery cases for graduation from plastic surgery residency from 50 to 150. To date, there has been no research into how this has impacted resident aesthetic surgery training focusing on the resident perception.

Objectives: We sought to evaluate resident perception and satisfaction with their aesthetic surgery training before and after the ACGME case log requirement increase to assess its impact on training and comfort level.

Background: The opioid epidemic demands changes in perioperative pain management. Of the 33,000 deaths attributable to opioid overdose in 2015, half received prescription opioids. Multimodal analgesia is a practice-altering evolution that reduces reliance on opioid medications.

Cyanobacteria are important photosynthetic organisms inhabiting a range of dynamic environments. This phylum is distinctive among photosynthetic organisms in containing genes encoding uncharacterized cystathionine β-synthase (CBS)-chloroplast protein (CP12) fusion proteins. These consist of two domains, each recognized as stand-alone photosynthetic regulators with different functions described in cyanobacteria (CP12) and plants (CP12 and CBSX).

Background: Migraine headache has been attributed to specific craniofacial peripheral nerve trigger sites. Some have postulated that hypertrophy of the corrugator muscles causes compression of the supraorbital and supratrochlear nerves, resulting in migraine headache. This study uses morphometric evaluation to determine whether corrugator anatomy differs between patients with migraine headache and control subjects.

Background: Previous studies have demonstrated that programs emphasize United States Medical Licensing Examination scores, publications, and geography in creating rank lists. The authors aimed to quantify the importance of geography and to determine how eliminating geographic preferences would affect Match outcomes.

Methods: The Match algorithm was implemented and validated on 6 years of deidentified data from the San Francisco Match (2009 to 2014).

Background: Closed-suction drains are widely used to reduce the incidence of seroma whenever potential spaces are surgically created. However, few studies have examined the parameters that affect drain efficacy.

Methods: An in vitro model was created to assess the effects of tubing length, tubing size, tubing type, fluid viscosity, fluid clotting, evacuator type, evacuator squeeze method, evacuator fill, and evacuator pressure on the performance of closed-suction drains.

Synthetic micro- and nanomotors (MNMs) are tiny objects that can autonomously move under the influence of an appropriate source of energy, such as a chemical fuel, magnetic field, ultrasound, or light. Chemically driven MNMs are composed of or contain certain reactive material(s) that convert chemical energy of a fuel into kinetic energy (motion) of the particles. Several different materials have been explored over the last decade for the preparation of a wide variety of MNMs.

Background: Musculoskeletal injuries are more common among surgeons than among the general population. However, little is known about these types of injuries among plastic surgeons specifically. The authors' goals were to evaluate the prevalence, nature, causes, and potential solutions of these musculoskeletal injuries among plastic surgeons in three different countries: the United States, Canada, and Norway.

Background: Carbonic anhydrases (CAs) are ubiquitous, essential enzymes which catalyze the conversion of carbon dioxide and water to bicarbonate and H ions. Vertebrate genomes generally contain gene loci for 15-21 different CA isoforms, three of which are enzymatically inactive. CA VI is the only secretory protein of the enzymatically active isoforms.

Purpose: Open abdominal wall reconstruction is often a complex endeavor, usually performed on patients with multiple risk factors and co-morbidities.

Methods: In this article, we review soft tissue management techniques that can optimize the skin and subcutaneous tissue, with the goal of reducing surgical-site occurrences.

Results: Regardless of the hernia repair technique used, outcomes can be highly dependent on the appropriate management of the skin and subcutaneous tissue.

Background: In abdominal wall reconstruction, adequate pain control and minimization of narcotic consumption are essential to improving patient outcomes and satisfaction. Previous studies have examined the role of individual strategies, such as neuraxial analgesia and multimodal analgesia. However, there has not been a study that examined all potential determinants of postoperative narcotic requirements, including intraoperative strategies.
