Effects of dielectric barrier discharge atmospheric cold plasma (DACP) treatment on the inactivation of Salmonella and the storability of grape tomato were investigated. Grape tomatoes, with or without inoculation with Salmonella, were packaged in a polyethylene terephthalate (PET) commercial clamshell container and cold plasma-treated at 35 kV at 1.1 A for 3 min using a DACP system equipped with a pin-type high-voltage electrode. DACP treatment inactivated Salmonella (p < 0.05) without altering the color or firmness of the grape tomatoes (p > 0...

Aortic surgery is sometimes complicated by aortic arch anomalies. This tutorial illustrates the technique of single-stage thoracic aorta replacement and aortic valve replacement via a clamshell thoracotomy in acute aortic arch dissection with proximal aneurysms of the left subclavian artery and an aberrant right subclavian artery. The advantage of this technique is that only brief partial hypothermic circulatory arrest is required and the procedure can be performed with one quadrifurcated tube graft.

South Florida is home to a number of native species of orchids. The Florida Panther National Wildlife Refuge has 27 known species, including Prosthechea cochleata, the clamshell orchid, which is listed as endangered on Florida's Regulated Plant Index. In a prior study done on this species in Mexico, P. cochleata was found to produce no floral fragrance at the particular study location. However, blooming orchids of this species at the University of Florida in Gainesville, were noted to be fragrant. In this paper, we document the presence of floral fragrance compounds from P...

BACKGROUND: We evaluated the effects of tailoring the operative approach on major surgical site complications and outcomes in lung transplant recipients. PATIENTS AND METHODS: Beginning in July 2013, bilateral lung transplants at a single institution were performed either through sternotomy or clamshell depending on proximity of hilar structures by computed tomography (CT), anticipated complexity, past surgical history, and surgeon experience. Patient demographics and outcomes were collected in the institution's Transplant Information Services (TIS)...

N-Methyl-d-aspartate (NMDA) receptors, key neuronal receptors playing the central role in learning and memory, are heavily glycosylated in vivo. Astonishingly little is known about the structure, dynamics, and physiological relevance of glycans attached to them. We recently demonstrated that certain glycans on the ligand binding domain (LBD) of NMDA receptors (NMDARs) can serve as intramolecular potentiators, changing EC50 of NMDAR coagonists. In this work, we use molecular dynamics trajectories, in aggregate 86...

We report the successful surgical repair of a cervical aortic arch and diverticulum with a brain circulation anomaly through a clamshell incision. Because of the reliability of selective antegrade cerebral perfusion and superior exposure, we chose an approach through a clamshell incision. We describe the utility of this approach for treating a cervical aortic arch with a diverticulum.

NMDA receptors (NMDARs) contribute to several neuropathological processes. Novel positive allosteric modulators (PAMs) of NMDARs have recently been identified but their effects on NMDAR gating remain largely unknown. To this end, we tested the effect of a newly developed molecule UBP684 on GluN1/GluN2A receptors. We found that UBP684 potentiated the whole-cell currents observed under perforated-patch conditions and slowed receptor deactivation. At the single channel level, UBP684 produced a dramatic reduction in long shut times and a robust increase in mean open time...

A 62-yr-old male Southern Isabela giant tortoise (Chelonoidis vicina) had a 1-yr history of chronic, reoccurring pododermatitis on the palmar surface of the left forelimb. Aggressive wound management was instituted and included surgical debridement, vacuum-assisted closure, and orthotic boot support during healing. A custom fabricated, carbon fiber clamshell Charcot Restraint Orthotic Walker walking boot was utilized to reduce focal pressure over the wound during weight bearing and promote a more normal gait...

Clamshell (bilateral anterolateral thoracotomy combined to transverse sternotomy) is an invasive surgical approach that is helpful in particular situations, especially bilateral lung transplantation. The closure technique remains challenging because clamshell incision can end with override, separation, or sternal pseudarthrosis complications. We describe the use of new absorbable sternal pins to stabilize the sternal closure and to help avoid additional sternal complications.

The surgical treatment of diffuse thoracic aortic pathologies remains a challenge in aortic surgery for surgeons. Traditionally, these aortic diseases are treated with a 2-step approach known as the "elephant trunk procedure." This technique gives us an opportunity for the construction of the distal anastomosis during the initial operation. However, this staged approach is associated with a substantial overall mortality and morbidity. In order to improve the outcomes, few single-stage repair methods have been tried...

Engineering light-sensitivity into proteins has wide ranging applications in molecular studies and neuroscience. Commonly used tethered photoswitchable ligands, however, require solvent-accessible protein labeling, face structural constrains, and are bulky. Here, we designed a set of optocontrollable NMDA receptors by directly incorporating single photoswitchable amino acids (PSAAs) providing genetic encodability, reversibility, and site tolerance. We identified several positions within the multi-domain receptor endowing robust photomodulation...

The whooping cough agent, Bordetella pertussis , controls the expression of its large virulence regulon in a coordinated manner through the two-component system BvgAS. BvgS is a dimeric, multidomain sensor kinase. Each monomer comprises, in succession, tandem periplasmic Venus flytrap (VFT) domains, a transmembrane segment, a cytoplasmic Per-Arnt-Sim (PAS) domain, a kinase module, and additional phosphorelay domains. BvgS shifts between kinase and phosphatase modes of activity in response to chemical modulators that modify the clamshell motions of the VFT domains...
