#1
James R Hill, Avril A B Robertson
Target identification is a high-priority, albeit challenging, aspect of drug discovery. Diazirine-based photoaffinity probes (PAPs) can facilitate the process by covalently capturing transient molecular interactions. This can help identify target proteins and map the ligand's interactome. Diazirine probes have even been incorporated by cellular machinery into proteins. Embarking on the synthesis of customized PAPs, containing either an aliphatic or trifluoromethyl phenyl diazirine, can be a considerable endeavor, particularly for medicinal chemists and chemical biologists new to the field...

Introduction: High pulmonary vascular resistance (PVR) in orthotopic heart transplantation (OHT) candidates is a risk factor of right ventricle failure after the procedure. However, the increase of PVR may be a consequence of the life-threatening deterioration of the left ventricle function. The use of mechanical circulatory support (MCS) seems to be the best solution, but it is reimbursed only in active OHT candidates. Aim: We performed a retrospective analysis of MCS effectiveness in maintaining PVR at values accepted for OHT...

Lymphangioleiomyomatosis (LAM) is a rare diffuse cystic lung disease. Knowledge on LAM-related pulmonary hypertension (PH) is limited. This study aimed to analyze the clinical characteristics of LAM with elevated pulmonary artery pressure (PAP) and evaluate the potential efficacy of sirolimus. The study involved 50 LAM patients who underwent echocardiography. According to the tricuspid regurgitation velocity (TRV), these patients were divided into the TRV ≤ 2.8 m/s group and TRV > 2.8 m/s group. Both groups comprised 25 females with an average age of 38...

The neurochemical effects of adenosine signaling in small-fiber neuropathy leading to neuropathic pain are yet to be explored in a direct manner. This study examined this system at the level of ligand (via the ectonucleotidase activity of prostatic acid phosphatase, PAP) and adenosine A1 receptors (A1Rs) in resiniferatoxin (RTX) neuropathy, a peripheral neurodegenerative disorder which specifically affects nociceptive nerves expressing transient receptor potential vanilloid type 1 (TRPV1). We conducted immunohistochemistry on dorsal root ganglion neurons (DRG), high-performance liquid chromatography (HPLC) for functional assays, and pharmacological interventions to alter PAP and A1Rs in mice with RTX neuropathy...

Telomerase Reverse Transcriptase (TERT) is the main catalytic sub-unit of telomerase, a reverse transcriptase enzyme. Telomerase expression is regulated at many levels, with numerous studies suggesting that up-regulation of human TERT gene (hTERT) at transcriptional level results in immortal cell phenotype associated with cancer. The aim of this study is to determine the correlation between hTERT expression and different cervical precursor lesions, as well as with cervical cancer in patients with confirmed Human papillomavirus (HPV) infection...

BACKGROUND: Invasive fungal infections (IFI) represent a common side effect of allogeneic hematopoietic stem cell transplant (allo-SCT), resulting in increased non relapse mortality (NRM) and reduced overall survival (OS) rates. 75-days of Fluconazole 400 mg/day represents the standard primary antifungal prophylaxis (PAP) after allo-SCT, especially for low-risk transplants. However, the ideal dosage of fluconazole has never been tested. METHODS: Here we report the experience of our institution on 113 consecutive patients receiving an allo-SCT from a HLA identical sibling between 1999 and 2015, where PAP consisted of fluconazole 100 mg/day only during the pre-engraftment phase...

BACKGROUND: Thrombelastography (TEG) fibrinolysis shutdown after trauma is associated with increased mortality due to hypercoagulability-associated organ failure. However, a lack of mechanistic data has precluded the development of novel interventions to treat shutdown. OBJECTIVES: To define the pathophysiology of TEG shutdown in severely injured, bleeding patients through secondary analysis of the PROPPR trial. METHODS: Fibrinolysis was characterized in PROPPR subjects using admission TEG lysis at 30 minutes (LY30) or plasmin-antiplasmin (PAP) levels...

Rong Chen, Shin-Ho Chung
Molecular dynamics simulations are employed to determine the inhibitory mechanisms of three drugs, 5-(4- phenoxybutoxy)psoralen (PAP-1), vernakalant and flecainide, on the voltage-gated K+ channel Kv1.5, a target for the treatment of cardiac arrhythmia. At neutral pH, PAP-1 is neutral, whereas the other two molecules carry one positive charge. We show that PAP-1 forms stable dimers in water, primarily through the hydrophobic interactions between aromatic rings. All three molecules bind to the cavity between the Ile508 and Val512 residues from the four subunits of the channel...

Pulmonary alveolar proteinosis (PAP) is a rare syndrome in which phospholipoproteinaceous matter accumulates in the alveoli leading to compromised gas exchange. Whole-lung lavage is considered the gold standard for severe autoimmune PAP and offers favorable long-term outcomes. In this case report, we describe the perioperative management and procedural specifics of a patient undergoing WLL for PAP in which an anesthesiologist serves as the proceduralist and a separate anesthesiologist provides anesthesia care for the patient...
