BACKGROUND Hyperbaric oxygen (HBO) therapy is sometimes used to assist in wound healing after major head and neck cancer surgery. However, there is concern that HBO treatments might enhance the growth of any residual microscopic disease. This was studied in a mouse model of squamous cell carcinoma (SCC). METHODS SCC-VII/SF tumor cells were cultured, and then injected (3 × 10(3) cells) into C3...

PURPOSE To compare semi-quantitative (SQ) and pharmacokinetic (PK) parameters for analysis of dynamic contrast enhanced MR data (DCE-MRI) and investigate error-propagation in SQ parameters. METHODS Clinical data was collected from five patients with type 2-neurofibromatosis (NF2) receiving anti-angiogenic therapy for rapidly growing vestibular schwannoma (VS). There were 7 VS and 5 meningioma...

Reaction centers (RCs) are integral membrane proteins that undergo a series of electron transfer reactions during the process of photosynthesis. In the Q(A) site of RCs from Rhodobacter sphaeroides, ubiquinone-10 is reduced, by a single electron transfer, to its semiquinone. The neutral quinone and anionic semiquinone have similar affinities, which is required for correct in situ reaction therm...

The maximum brightness of one of the prothoracic light organs of the West Indian elaterid beetles, Pyrophorus (measured at Princeton, New Jersey) was found to be .045 lambert, or .045 lumen per sq. cm. at 20 degrees C. This corresponds to .0002 candle for one organ, or .0004 candle for the pair of prothoracic organs.

Abstract Design and development of near-infrared (NIR) dyes with strong binding on the TiO 2 surface is inevitable for realization dye-sensitized solar cells (DSSCs) improved efficiency stability. A series NIR bearing different anchoring groups have been designed considering their suitability as sensitizers DSSCs based-on iodine-based redox electrolytes. Under Gaussian program, density function...

BACKGROUND The herb-pair, Salviaemiltiorrhizae (Danshen, DS) and Panaxnotoginseng (Sanqi,SQ), often occurs in traditional Chinese medicine prescriptions used for the treatment of cardiovascular diseases in clinics in Asian areas. Many commercial preparations containing the DS-SQ herb-pair were produced by various manufactures with the different production process. The raw materials were from di...
