A new, solvent-free method has been developed for the synthesis of 7-(2-carboxy-ethyl)-1,3,5-triaza-7-(phosphoniatricyclo)[3.3.1.13,7]decane (L). It is disclosed here that 1,3,5-triaza-7-phosphaadamantane (PTA) reacted cleanly with acrylic acid in a planetary ball mill resulting 88% yield corresponding P-carboxy-ethyl derivative, striking contrast to complete failure same product from reactants...

During a routine visit for nail care and diabetic neuropathy evaluation, laboratory tests were ordered for a 64-year-old man with a history of diabetes mellitus and hypertension. At the time, he had no symptoms of any acute problem. A serum separator tube was received and revealed sodium 162 mmol/L, potassium 3.8 mmol/L, chloride 88 mmol/L, CO2 20 mmol/L, and anion gap 54 mmol/L with normal blo...

Introduction: Accumulation of 5-oxoproline (pyroglutamic acid) is a rare cause of severe, high anion gap metabolic acidosis in adults. Case: A 21 year old lady presented at 39 weeks gestation in her first pregnancy with 2 weeks history of shortness of breath. She suffered from ear ache and had been taking Paracetamol on regular basis for a year. She was admitted to having regular alcohol intake...

INTRODUCTION Acute metabolic acidosis of non-renal origin is usually a result of either lactic or ketoacidosis, both of which are associated with a high anion gap. There is increasing recognition, however, of a group of acidotic patients who have a large anion gap that is not explained by either keto- or lactic acidosis nor, in most cases, is inappropriate fluid resuscitation or ingestion of ex...

Abstract Isolation of E -1,2-bis(4-bromophenyl)-1,2-diphenyl-ethylene from the E/Z isomer mixture obtained by a McMurry coupling reaction and this with imidazole followed N -alkylation n BuBr anion exchange yielded bisimidazolium tetraphenylethylene (TPE) derivative H 2 - 1 (PF 6 ) . The Ag O di-nuclear metallarectangle [Ag ( ](PF where two bis-NHC donors bridge silver atoms. Irradiation leads ...

A solution phase-based nanocapsule method was successfully developed to synthesize non-platinum metal catalyst-carbon supported Ag nanoparticles (Ag/C). XRD patterns and TEM image show Ag nanoparticles with a small average size (5.4 nm) and narrow size distribution (2-9 nm) are uniformly dispersed on the carbon black Vulcan XC-72 support. The intrinsic activity and pathway of oxygen reduction r...
