We report in situ synthesis of the first CF(3) oxonium salts, thermally unstable O-(trifluoromethyl)dibenzofuranium which furthermore have different counteranions (BF(4)-, PF(6)-, SbF(6)-, and Sb(2)F(11)-) ring substituents (tert-butyl, F, OCH(3)), by photochemical decomposition corresponding 2-(trifluoromethoxy)biphenylyl-2'-diazonium salts at -90 to -100 degrees C. The yields markedly increased order BF(4)- < PF(6)- SbF(6)- Sb(2)F(11)-. were fully assigned means (1)H (19)F NMR spectroscopy...
Homogeneous dispersions of reduced tungsten oxide and bronze nanoparticles with ternary additives Na, Tl, Rb, Cs have been prepared in the wet process examined for optical properties. The are found to show a remarkable absorption near infrared light while retaining high transmittance visible light. This property is highly suitable solar control filters automotive architectural windows.
In Saccharomyces cerevisiae, trehalase activity in crude extracts obtained from wild type cells was activated about 3-fold by preincubation with cAMP and ATP. The inactive fractionated DEAE-Sephacel chromatography the addition of cAMP-dependent protein kinase fraction presence Using extract bcy1 mutant which were deficient regulatory subunit kinase, stimulation observed absence cAMP. CYR3 had a high Ka value for phosphorylation reaction required concentration activation trehalase. Increased...

Nanoparticle dispersions of rare‐earth hexaborides have been prepared using a media agitation mill and examined for optical properties. High visible light transmittance coupled with strong absorption in the near‐infrared (NIR) wavelengths suitable solar control windows are reported hexaboride nanoparticle particle size dependence effect artifacts. Nanoparticulate LaB 6 shows largest NIR among hexaborides. is considered to arise from free electron plasmon resonance. On decreasing below 120...
Nanosize homogenous rod-like tungsten bronze CsxWO3 with excellent NIR shielding ability was successfully synthesized by a novel and facile water controlled-release solvothermal process (WCRSP).
Prostaglandins E1 and E2 stimulate cyclic AMP accumulation in pig epidermis human from patients with psoriasis. A1, A2 F2α are relatively ineffective. The fact that this stimulation is not inhibited by a β‐blocker (propranolol) the prostaglandin adrenaline additive indicates each drug acts independently on epidermal adenyl cyclase system. In other words, prostaglandins act site than β‐receptor of epidermis. additive; hence they probably same site. Concentrations E above 3 × 10−7 M effective...
We demonstrated the conversion of testosterone-4-14C to dihydrotestosterone (17β-Phydroxy-5α-androstan-17-one), tissue-active androgen, with 50–200 μg freeze-dried human hair follicles plucked from various regions. All thus far tested contained 5α-reductase activity. Under optimal conditions, activity in growing ranged 10–20 nmoles/100 mg dry wt/hr. In scalp, showed 3–8 times higher values than resting. other regions such as beard, axilla, chest, pubis, arms and legs, nearly same activities...
Nanoparticles of alkali-doped tungsten bronzes are an excellent near-infrared shielding material, but exhibit slight chromatic instabilities typically upon applications strong ultra-violet light or heating in humid environment, which acts detrimentally to long-life commercial applications. Origin the cesium-doped bronze has been investigated, and it found that coloration bleaching processes comprised electronic exchanges accelerate depress polaron excitation localized surface plasmon...
ABSTRACT Hypoparathyroidism is a disease of chronic hypocalcemia and hyperphosphatemia due to deficiency parathyroid hormone (PTH). PTH analogs the are interest as potential therapies. Accordingly, we examined pharmacological properties long-acting analog, [Ala1,3,12,18,22, Gln10,Arg11,Trp14,Lys26]-PTH(1-14)/PTHrP(15-36) (LA–PTH) in thyroparathyroidectomized (TPTX) rats, model HP, well normal monkeys. In TPTX single intravenous administration LA-PTH at dose 0.9 nmol/kg increased serum...
We studied the in vivo and vitro conversion of testosterone to dihydrotestosterone sebaceous glands microdissected from costovertebral Syrian hamsters. After intraperitoneal injection testosterone- 1,2-3H, was major radioactive steroid not only but also prostate seminal vesicles. On other hand, nontarget organs plasma contained very little or no dihydrotestosterone. Using newly devised micromethod for 5α-reductase assay with 15 25 μg tissue samples, we found that sufficient activity convert...
The cyclic adenosine 3',5'-monophosphate (cyclic AMP) content of pig skin was measured several seconds to minutes after removal the from body. It increased very rapidly, reached a maximum by 2 min (4 times higher than initial level), then decreased slowly. Propranolol injected into animal before or added did not suppress this phenomenon. practical significance finding (increase AMP level in ischaemia) is obvious-in order measure vivo, sample must be frozen immediately avoid an 'artificial'...
Abstract Structural and compositional changes of Cs‐doped hexagonal tungsten bronzes ( HTB ) with respect to variations in oxygen deficiency alkali content have been investigated detail through x‐ray diffraction Rietveld analysis, photoelectron spectroscopy, Raman spectroscopy. Cs‐ crystallized a reductive atmosphere is evidenced generally contain plenty defects, general formula, Cs x WO 3− y (0.20 ≤ 0.32, 0 < 0.46), proposed. Lattice parameters are observed vary according the relation, c...
N,N'-Difluoro-2,2'-, -2,4'-, -3,3'-, -4,4'-bipyridinium and substituted N,N'-difluoro-2,2'-bipyridinium bis(triflates), bis(tetrafluoroborates), bis(hexafluorophosphates), bis(hexafluoroantimonates) 1−9 were synthesized in high yields by the direct fluorination of a mixture bipyridyl Lewis acid, Brønsted or alkali metal salt an acid. The higher homologues, trimer 10 polymer 11, also synthesized. Unsubstituted electron-donating group-substituted N,N'-difluorobipyridinium salts are stable...
Polycrystalline In2O3 films with high crystallinity were prepared by annealing the amorphous deposited at room temperature using dc/rf sputtering method. General electronic behaviors of both these and polycrystalline have been investigated means Hall effect resistivity measurements temperatures between 4.2 300K. For films, ionized impurity scattering dominates transport, mobility agrees well theory degenerate semiconductors divalent centers. On other hand, conduction mechanism is governed...
