In a study of collodion membranes which had been coated with films of gelatin or egg albumin, it was found that the presence of the protein reduced the rate of flow of water through the membranes, as would be expected if the protein film were formed on the wails of the pores. ~ In order to determine the thickness of such films, an at tempt has been made to estimate the size of pores in membrane...

With the demonstration that the generalized Shwartzman reaction could be produced in pregnant rats by simply adding an oxidized lipid to an otherwise ordinary diet (1, 2), at tention is naturally directed to the material in the oxidized lipid tha t m ay be responsible for this unique pathologic change. Stamler's observations that the preliminary diet is low in tocopherol, and that supplements o...

One of the problems engaging current interest in field theory is the problem of determining which fields are (~ elementary ,> in some fundamenta l sense, and which are not. An equally, if not more, import~nt, problem is tha t of finding ,~ guiding principe for writina" fundamenta l interactions of fields. The only such principle which exists at the present time seems to be the gauge-principle. ...

Due to large numbers of increasing amount of customers, the congestion in cellular networks during summit hour and at hot spot areas is a very serious problem which is faced by almost every cellular company and their customers mainly in large metropolitans now a days. Solution of this congestion is very easy and straightforward as it can be resolve by enhancing and upgrading the infrastructure....

DURING the past decade there appears to have been an increase in the incidence of chronic nonspecific ulcerative colitis in the southwest. Since 1949, I have removed all, or a part , of the colon and rectum f rom 40 patients suffering with this disease. This is a relatively small num be r of patients, but it is significant that only twe i'teostomies had been performed for ulcerative colitis in ...

The syndrome of disseminated intravascular coagulation (DIC) 1 is a recognized complication of acute hemolytic episodes in both man (1-3) and laboratory animals (4, 5) and has been induced experimentally in monkeys and dogs by infusion of autologous red blood cell stroma (6, 7). The mechanism of stromainduced D I C may be analogous to the demonstrable procoagulant activity of red cell membrane ...

Nord (2011) criticizes standard arguments which assert that consistency requires that future health benefits must be discounted at the same rate as future costs in cost-effectiveness analysis (CEA). He suggests these arguments are misguided because they require transitivity of preferences across decision contexts and that it can be appropriate to discount health at different rates depending on ...

Muscle degeneration and a shock syndrome, which frequently results in death, follow the release of limb tourniquets. Albumin and other plasma components are transferred into the affected muscle tissue (1-4) while toxic products of autolysis and hemolytic substances appear in the circulating blood (5-7). I t is possible that this abnormal transfer results in part from damage of capillaries and m...

O u r purpose in this paper is to present some experimental findings that have a bear ing on the t ransport of sodium a nd potassium across the m e m b r a n e of the squid giant axon. As in a variety of cellular types that actively t ranspor t sodium ions, a marked drop in the efflux of sodium ions from squid g iant axons occurs when potassium ions are removed from the external solution (Caldw...

Mycobacteria owe their success as pathogens to their ability to persist for long periods within host cells in asymptomatic, latent forms before they opportunistically switch to the virulent state. The molecular mechanisms underlying the transition into dormancy and emergence from it are not clear. Here we show that old cultures of Mycobacterium marinum contained spores that, upon exposure to fr...
