The human P2Y2 receptor (hP2Y2R) is a G protein-coupled receptor that shows promise as a therapeutic target for many important conditions including anti-metastatic cancer therapy and more recently for the treatment of idiopathic pulmonary fibrosis. As such, there is a need for new hP2Y2R antagonists and molecular probes to study this receptor. Herein, we report the development of a new series of non-nucleotide hP2Y2R antagonists leading to the discovery of a series of fluorescent ligands containing different linkers and fluorophores based on the known, non-nucleotide hP2Y2R antagonist AR-C118925 (1)...

BACKGROUND: The proportion of patients with kidney failure at time of liver transplantation is at an historic high in the United States. The optimal timing of kidney transplantation with respect to the liver transplant is unknown. METHODS: We used a modified cost-effectiveness analysis to compare four strategies: the old system ("pre-OPTN"), the new Organ Procurement Transplant Network (OPTN) system since August 10, 2017 ("OPTN"), and two strategies which restrict simultaneous liver-kidney transplants ("safety net" and "stringent")...

PURPOSE OF REVIEW: Microcirculatory alterations play a major role in the pathogenesis of shock. Monitoring tissue perfusion might be a relevant goal for shock resuscitation. The goal of this review was to revise the evidence supporting the monitoring of peripheral perfusion and microcirculation as goals of resuscitation. For this purpose, we mainly focused on skin perfusion and sublingual microcirculation. RECENT FINDINGS: Although there are controversies about the reproducibility of capillary refill time in monitoring peripheral perfusion, it is a sound physiological variable and suitable for the ICU settings...

Achieving an osseous fusion across the lumbosacral spine is still challenging in spine surgery. For the long multisegmental fusion surgery, it is crucial to build a robust and substantial foundation, which sometimes necessitates the distal spinal fixation to the pelvis. The pelvic fixation technique involves advancing the screw through the alar, thereby providing more purchase across the sacroiliac joint and into the ilium. The S2 alar iliac screws can obtain immediate stability and proper biomechanical strength of constructs...

Cilia are highly-conserved organelles projecting from the cell surface of nearly every cell type in vertebrates. Ciliary proteins have essential functions in human physiology, particularly in signaling and organ development. As cilia are a component of almost all vertebrate cells, cilia dysfunction can manifest as a constellation of features that characteristically include, retinal degeneration, renal disease and cerebral anomalies. The terminology "Ciliopathies" refers to inherited human disorders caused by genetic mutations in ciliary genes, leading to cilia dysfunctions that form an important and ever expanding multi-organ disease spectrum...

Multiple genetic mutations within melanoma not only cause lesion-specific responses to targeted therapy but also alter the molecular route of resistance to that therapy. Inactivation of PTEN occurs in up to 30% of melanomas, frequently with a concurrent activating BRAF mutation. PTEN loss regulates both acquired and intrinsic drug resistance. Here we show that AXL/AKT axis mediated-resistance to BRAF inhibitor (BRAFi) depends upon PTEN status in melanoma. Hyperactivation of both ERK and AKT pathways was associated with BRAFi resistance in melanoma with wildtype PTEN...

Progress in achieving "universal access to safe, affordable surgery, and anesthesia care when needed" is dependent on consensus not only about the key messages but also on what metrics should be used to set goals and measure progress. The Lancet Commission on Global Surgery not only achieved consensus on key messages but also recommended 6 key metrics to inform national surgical plans and monitor scale-up toward 2030. These metrics measure access to surgery, as well as its timeliness, safety, and affordability: (1) Two-hour access to the 3 Bellwether procedures (cesarean delivery, emergency laparotomy, and management of an open fracture); (2) Surgeon, Anesthetist, and Obstetrician workforce >20/100,000; (3) Surgical volume of 5000 procedures/100,000; (4) Reporting of perioperative mortality rate; and (5 and 6) Risk rates of catastrophic expenditure and impoverishment when requiring surgery...

Transoceanic Gliders are Autonomous Underwater Vehicles (AUVs) for which there is a developing and expanding range of applications in open-seas research, technology and underwater clean transport. Mature glider autonomy, operating depth (0-1000 meters) and low energy consumption without a CO2 footprint enable evolutionary access across ocean basins. Pursuant to the first successful transatlantic glider crossing in December 2009, the Challenger Mission has opened the door to long-term, long-distance routine transoceanic AUV missions...

Contextual threat learning reflects two often competing processes: configural and elemental learning. Configural threat learning is a hippocampal-dependent process of forming a conjunctive representation of a context through binding of several multi-modal elements. In contrast, elemental threat-learning is governed by the amygdala and involves forming associative relationships between individual features within the context. Contextual learning tasks in humans however, rarely probe if a learned fear response is truly due to configural learning vs...

BACKGROUND: Quantifying right ventricular function in patients with a systemic right ventricle (RV) is difficult but important for prognosis. Tissue motion annular displacement tracks displacement of the tricuspid annulus toward the apex. We evaluated this measure alongside fractional area change (FAC) on patients with single, RV prior to the bidirectional Glenn procedure. We tested both measures for correlation with outcomes. METHODS: Retrospective measurement of tissue motion annular displacement and FAC was performed on echocardiographic clips obtained prior to the bidirectional Glenn...

BACKGROUND: First-stage single-ventricle palliation is challenging to manage, and significant interstage morbidity and mortality remain. Prior computational and in vitro studies of the assisted bidirectional Glenn (ABG), a novel first-stage procedure that has shown potential for early conversion to a more stable augmented Glenn physiology, demonstrated increased pulmonary flow and oxygen delivery while decreasing cardiac work, as compared to conventional stage-1 alternatives. This study aims to identify optimal shunt designs for the ABG to improve pulmonary flow while maintaining or decreasing superior vena caval (SVC) pressure...

BACKGROUND: Salmeterol (a long acting beta2-agonist) is a chiral molecule. (RR)-salmeterol is responsible for pharmacological effect, but basic knowledge of enantioselective pulmonary pharmacodynamics and pharmacokinetics of salmeterol remains unknown. There are safety concerns with (S)-enantiomers of beta2-agonists, with suggestions that these enantiomers may increase bronchial hyperresponsivneness in asthma patients. METHODOLOGY: Horses (n = 12) received racemic (rac-) salmeterol 250 μg via inhalation...
