C−H Bond Activation by Dicationic Platinum(II) Complexes [PDF]
, 2007 Double protonolysis of diimine platinum dimethyls [(N-N)PtMe_2] (N-N ═ ArNC(Me)C(Me) ═ NAr) generates dicationic Pt(II) complexes that can activate a variety of C−H bonds, liberating 1 equiv of acid and forming organoplatinum species that are moderately ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Cobalt-catalyzed nucleophilic addition of the allylic C(sp3)–H bond of simple alkenes to ketones
Beilstein Journal of Organic Chemistry, 2018 We herein describe a cobalt/Xantphos-catalyzed regioselective addition of simple alkenes to acetophenone derivatives, affording branched homoallylic alcohols in high yields with perfect branch selectivities.

Computational exploration of the reaction mechanism of the Cu+-catalysed synthesis of indoles from N-aryl enaminones [PDF]
Royal Society Open Science, 2016 We have studied the role of Cu+-phenantroline as a catalyst in the cyclization of N-aryl-enaminones using density-functional theory computations. The catalyst was found to bind the substrate upon deprotonation of its eneaminone, and to dramatically ...

Effects of Low Cell pH and Elevated Inorganic Phosphate on the pCa-Force Relationship in Single Muscle Fibers at Near-Physiological Temperatures [PDF]
, 2014 Intense muscle contraction induces high rates of ATP hydrolysis with resulting increases in Pi, H+, and ADP, factors thought to induce fatigue by interfering with steps in the cross-bridge cycle.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild
