Semicarbazide, a lathyrogen, was given to growing rats to elucidate the consequences of altering the molecular structure of fibrous proteins within the lung. Static pressure-volume (P-V) measurements during deflation of saline-filled lungs showed normal recoil pressure and compliance values within the physiological range of lung volume. Quasi-static P-V measurements were also normal during slow...

-Stoichiometric reactions of metal hydroxycarbonates with the acid trans-l,2cyclohexanediaminotetraacetic acid (H4CDTA) in water under reduced pressure yielded [Cu(H2CDTA)]'H20 (I) and [Ni(H2CDTA)(H20)]'4H20 (II). Both compounds were characterized by TG-DTA analysis, spectral properties (IR, reflectance and RSE) and Xray diffraction. In I the copper(II) atom exhibits a distorted square-base coo...

We report a case of a 40 year old man with portal hypertension caused by a splenic arteriovenous fistula that was diagnosed at laparotomy. He presented with bleeding esophageal varices and was initially treated by sclerotherapy. At laparotomy, portal pressure was 40 cmH20 but fell to 20 cm H20 after the fistula was treated with splenectomy. All symptoms disappeared shortly after operation ...

Electronic structure calculations using the local density functional method with non-local norm-conserving pseudopotentials, ab initio molecular dynamics simulations, and a novel method of all-quantum simulations, combining a quantum path-integral description of the nuclear degrees of freedom with concurrent electronic structure calculations of the Born-Oppenheimer potential energy surface, wer...

The transition state region of the reaction OH + H2 -. H2O + H is investigated by photoelectron spectroscopy of the H3Oand D30anions. The peaks observed in the spectra are from a combination of vibrational progressions and overlapping anion -. neutral electronic transitions. The photoelectron angular distributions indicate that two processes contribute to the spectra; these are assigned to phot...

The monoclinic compound CuC40 4-2 H ;0 (space group P 2t/c) was prepared from aqueous acetate buffered solution. The structure was solved from a twinned crystal. Chains consisting of squarate dianions and Cu2 + , which is coordinated octahedrally in a strongly distorted manner, are the main feature. Only two squarate oxygen atoms contribute considerably to the coordination of Cu2 .̂ Neighbouring...

s tructural change is defined as a change in the relative weight of the important constituents of the macro-economic indicator such as production, taxes, imports and exports, workforce etc. since the structure change is one of the main reasons for the growth and economic development of countries, the investigation of the trend of changes in economic important constituents is important. tax as a...

We tested the hypothesis that human recombinant tumor necrosis factor-a (TNF) promotes pulmonary edema by neutrophil-dependent effects on the pulmonary vasculature. The isolated guinea pig lung was perfused with phosphate-buffered Ringer's solution with or without human neutrophils. The infusion of neutrophils (9x 106 total) into lungs isolated after the in vivo administration of TNF (3.2x 10' ...

The photo-oxidation process by combination of UV light and H20 2 generates hydroxyl radicals which are capable of oxidising many organic compounds which are refractory type and difficult to oxidize by conve nt ional' chemical treatment. In the present study, photo-oxidation of Direct Yellow 12 (DY 12) dye has been carri ed out in an annular type photoreactor using 8 Watt low pressure mercury la...
