BACKGROUND AND OBJECTIVES: Substance use disorder (SUD) is a widespread problem but physicians may feel inadequately prepared to provide addiction care. We sought to assess current addiction medicine curricula in US family medicine residencies (FMRs) and evaluate barriers to improving or implementing addiction medicine curricula. METHODS: Questions regarding addiction medicine training were added to the December 2015 Council of Academic Family Medicine Educational Research Alliance (CERA) survey to US FMR program directors to evaluate each FMR's curriculum, potential workforce production, perceived barriers to improving or implementing curricula and faculty training in addiction medicine...

BACKGROUND: Histone lysine demethylases (KDMs) are well-recognized targets in oncology drug discovery. They function at the post-translation level controlling chromatin conformation and gene transcription. KDM1A is a flavin adenine dinucleotide-dependent amine oxidase, overexpressed in several tumor types, including acute myeloid leukemia, neuroblastoma and non-small-cell lung cancer. Among the many known monoamine oxidase inhibitors screened for KDM1A inhibition, tranylcypromine emerged as a moderately active hit, which irreversibly binds to the flavin adenine dinucleotide cofactor...

BACKGROUND: Liposomes have been widely used in the gene transfection and the drug delivery systems due to their excellent biocompatibility and encapsulation ability, especially, the ability to deliver the gene/drug into the cells via the membrane fusion. Thermosensitive liposoems have been proven to be a precise and effective method for cancer treatment in many preclinical studies. But the imperfect crystalline arrangement between grains occurred, resulting in planar defects at the boundaries of membranes, compromising the stability of thermosensitive liposomes...

C-H alkylations with challenging β-hydrogen-containing alkyl halides were accomplished with sustainable MnCl2 as the catalyst under phosphine-ligand free conditions. The proximity-induced benzamide C-H activation occurred with ample substrate scope through rate-determining C-H metalation, also setting the stage for manganese-catalyzed oxidative C-H methylations.

Zhigao Shen, Gianpiero Cera, Tobias Haven, Lutz Ackermann
The design of trisubstituted triazoles set the stage for proximity-induced iron-catalyzed C-H activation of benzyl and aryl amines with ample scope. Thereby, C-H alkylations and C-H arylations proved viable with high levels of chemo and positional selectivities by means of racemization-free iron catalysis with the reusable triazole being removed in a traceless fashion.

Intravenous (IV) infusion of adenosine represents the gold standard for measuring fractional flow reserve (FFR). However, IV adenosine is more expensive and time-consuming compared with intracoronary (IC) boluses of adenosine. We conducted a meta-analysis of studies comparing IC with IV adenosine for FFR assessment in the same coronary lesions. We searched for studies comparing IC with IV adenosine and reporting absolute FFR values or rate of abnormal FFR for both routes. Prespecified subgroup analysis was performed to appraise studies using low-dose (<100 μg) or high-dose IC adenosine (≥100 μg)...

Left ventricle-right atrial communication could be congenital (Gerbode defect) or acquired as a complication of surgery or infective endocarditis and leads to volume overloading of pulmonary circulation. Two types, direct and indirect types are known depending on the involvement of septal tricuspid leaflet. Transcatheter closure of this defect is feasible and appears an attractive alternative to surgical management. Various devices like Amplatzer duct occluder I, II, Muscular ventricular septal defect device etc...

BACKGROUND: Percutaneous patent foramen ovale (PFO) closure has become a routine procedure and was proven to be safe and feasible. In a recently published pooled analysis of randomized trials, percutaneous PFO closure was shown to more effectively reduce recurrent stroke when compared with medical therapy in patients with cryptogenic strokes. However, procedural safety and closure rate are device dependent. METHODS: We performed a propensity-score matched comparison of 28 patients undergoing percutaneous PFO closure using the Cera PFO occluder (CPO) with 28 patients who received the Amplatzer PFO occluder (APO)...

Pradipta Chakraborty, Enrico Di Cera
Conformational selection (CS) and induced fit (IF) are two widely used interpretations of binding of a ligand to biological macromolecules. Both mechanisms envision a two-step reaction in which a conformational transition either precedes (CS) or follows (IF) the binding step. Under pseudo-first-order conditions where the ligand is in excess compared to the macromolecule, both mechanisms produce two relaxations. A fast one eventually increases linearly with ligand concentration and reflects the binding interaction...

P450 activity is required to metabolically activate many chemical carcinogens, rendering them highly genotoxic. CYP3A4 is the most abundantly expressed P450 enzyme in the liver, accounting for most drug metabolism and constituting 50% of all hepatic P450 activity. CYP3A4 is also expressed in extrahepatic tissues, including the intestine. However, the role of CYP3A4 in activating chemical carcinogens into potent genotoxins is unclear. To facilitate efforts to determine whether CYP3A4, per se, can activate carcinogens into potent genotoxins, we expressed human CYP3A4 in the DNA-repair mutant (rad4 rad51) strain of budding yeast Saccharomyces cerevisiae and tested the novel, recombinant yeast strain for ability to report CYP3A4-mediated genotoxicity of a well-known genotoxin, aflatoxin B1 (AFB1 )...

BACKGROUND: The acute effects of statin loading dose (LD) on platelet reactivity in patients with chronic stable angina (CSA) are not completely clear. HYPOTHESIS: We hypothesized that LDs of atorvastatin and rosuvastatin have different pharmacodynamic acute effects on platelet aggregability in CSA patients with baseline normal platelet reactivity while on dual antiplatelet therapy (DAPT). METHODS: From September 2011 to February 2014, all consecutive CSA patients on chronic DAPT (aspirin and clopidogrel) were evaluated before elective percutaneous coronary intervention (PCI)...
