Three new rearranged ent-kaurane-type diterpenoids (1-3) and seven new ent-kaurane-type diterpenoids (4-10) have been isolated from the liverwort Jungermannia atrobrunnea. Their structures were determined by extensive spectroscopic techniques and X-ray crystallographic analysis. The absolute configurations of these compounds were clarified by CD spectroscopic studies. Compound 1 is the first ex...

A known ent-kaurane diterpenoid, ent-19-al-17,16β-dihydroxykaurane (1), together with the new one, ent-3β, 16β, 19-trihydroxykaurane (2), called leptophyllin, were isolated from aerial parts of Baccharis leptophylla. Their structures were established on the basis of NMR spectroscopic analysis. Based on this study the H and C NMR spectral data of compound (1) were completed by means of 2D NMR te...

The title compound, enmenol, C(20)H(30)O(6), a natural ent-kaurane diterpenoid, comprises five fused rings, four of which are six-membered. Cyclo-hexane ring A adopts a chair conformation, rings B and C adopt boat conformations, while ring D has an envelope conformation, and two intramolecular O-H⋯O interactions occur. In the crystal, inter-molecular O-H⋯O hydrogen bonds generate a two dimensio...

the objective of this study was to evaluate lactic flora identification in fresh (one-day) and ripened (90-day) koozeh cheese samples as one of the raw milk cheeses. in first step, in order to isolate the different genera of lactic acid bacteria (lab), selective and differential (corresponding) media were used as follow: mrs for lactobacilli and pediococci, mrs+ vancomycin for leuconostocs, m17...

OBJECTIVE To describe the documentation of care for the usual range of ear, nose, and throat (ENT) problems seen in primary care as a basis for developing a computerised information system to aid quality assessment. DESIGN Descriptive study of the pattern of ENT problems and diagnoses and treatment as recorded in individual case notes. SETTING The primary health care centre in Mjölby, Swede...

INTRODUCTION Posttympanostomy tube otorrhea also known as acute otitis media with tympanostomy tubes (AOMT) occurs in 15% to 80% of children with tympanostomy tubes. Its management is fairly standardized among pediatric ear, nose, and throat (ENT) physicians owing to recommendations published by the American Academy of Otolaryngology-Head and Neck Surgery. Pediatric emergency medicine (EM) phys...
