I.~fluorine-18 Labeled Corticosteroids and Progestins for Receptor-Based Imaging of the Brain and of Breast Tumors. II.~Synthesis and NMR Spectrum of (carbon-13(18))-Meso-Hexestrol
… of mesylate or triflate precursors. Tissue distribution studies in adrenalectomized, mature male rats showed no brain uptake for three compounds, while the fourth was taken up by the brain but did not selectively localize in target tissues (hippocampus, cortex). Two compounds showed …

Fluorine-18-labeled estrogens, progestins and corticosteroids for receptor-based imaging of breast tumors and target areas of the brain
… fluoro-17$\beta$-estradiol (FES). Tissue distribution studies of 1 and 2 in immature female rats show high selectivity for target tissue (T, uterus) vs non-target (NT, muscle and lung), with T/NT ratios being 43 and 17 at one hour after injection for 1 and 2, respectively. The parent …

Smectite/Illite Distribution and Diagenesis in the South Timbalier Area, Northern Gulf of Mexico
Clays and clay mineral distribution studies are important for understanding the geological history of the Gulf of Mexico Basin, but few studies document any subsurface clay mineral distribution in the Gulf of Mexico. Shale samples from nine wells (30 samples) in the South Timbalier protraction were …

Distributional Ecology of Vegetation in the Vernal Pools of the Santa Rosa Plateau, California
<p>Interpool distribution studies of 10 vernal pools on the Santa Rosa Plateau found area to be the best single predictor of species richness in each type of regression model evaluated. Area predicted most accurately in a mixed linear-curvilinear regression model (y = a + b log x). Area appeared to …

Design, synthesis, and biochemical evaluation of three types of hexestrol-based probes for estrogen receptor: Fluorine-18 radiopharmaceuticals, bivalent ligands and diazirine photoaffinity reagents
… a mesylate and triflate precursor. Preliminary studies on the unlabeled compounds showed them to have low lipophilicity and good receptor binding affinity; these results were reflected in the tissue distribution studies of the radiolabeled compounds with moderate selective uptake in target …

"The Synthesis and Biological Evaluation of Integrated and Conjugated Re/tc-99m-Containing ""3+1"" and Cyclopentadienyltricarbonyl (Cptm) Estrogen Complexes as Receptor-Based Imaging Agents for Breast Cancer"
… complex employing an amide linkage (67b, 24%). Studies showed that the Tc analogs were too lipophilic for in vivo use, so we pursued the synthesis of CpTR amides containing ether functionalities in the 7alpha side-chain. This led to two new complexes: short-chain monoether complex 88, and …

On-line evaluation of mode field distribution in optical fibers
… thus rendering a sophisticated tool for modal distribution studies. The system has been found useful in fiberdyne measurements and speckle pattern analysis thus leading to information on the propagating modes. Chapters I and 2 give a brief introduction to fiber optic systems and mode theory …

CNS delivery of antisense oligodeoxynucleotides using biodegradable microspheres
… as observed by a slower efflux profile. In vivo distribution studies of antisense oligodeoxynucleotides demonstrated that the use of microspheres provided a sustained-release over more than 2 days compared to 12 hours of the naked molecule. Efficacy of antisense oligodeoxynucleotides was …

Effervescent proliposomes for aerosol delivery to paranasal sinuses
… of 35.52±11.11 cm2 without pulsation. Drug distribution studies indicated that the Pari Sinus deposited 10.47±2.9% drug, while the Pari Sprint deposited only 4.6±1.4%. The degree of drug loss was higher with conventional liposomes in the Pari Sinus nebulizer, indicating that the degree of …
