It is difficult to retain and localize radioactive, water-soluble compounds within plant cells. Existing techniques retain water-soluble compounds with varying rates of efficiency and are limited to processing only a few samples at one time. We developed a modified pressure infiltration technique for the preparation of microautoradiographs of (14)C-labeled, water-soluble compounds in plant tiss...

In the title compound, [Mn(C(7)H(5)O(3))(2)(C(14)H(12)N(2))(H(2)O)]·C(14)H(12)N(2)·H(2)O, the Mn(II) ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand, two monodentate 3-hydroxy-benzoate anions (3-HBA) and one water mol-ecule in a distorted trigonal-bipyramidal environment. An uncoordinated dmphen and an uncoordinated water mol-ecule cocrystallized with each com...

Although carbonyl oxides, "Criegee intermediates," have long been implicated in tropospheric oxidation, there have been few direct measurements of their kinetics, and only for the simplest compound in the class, CH2OO. Here, we report production and reaction kinetics of the next larger Criegee intermediate, CH3CHOO. Moreover, we independently probed the two distinct CH3CHOO conformers, syn- and...

Bryophytes are an important component of plant diversity, may be found from sea level to mountaintops, and particularly conspicuous on the Azores islands. These plants rely environmental water, which acquires intercepting rain dew (liquid water) uses fog (water vapor), transports both externally, by capillary forces, internally, in different cells (specialized or not). This study characterizes ...

An outbreak of 160 cases of viral hepatitis which occurred in Shahbad, Haryana, was investigated to ascertain the agent, cause of the outbreak and to initiate remedial measures. Out of the 30 samples tested, 26 (86.7%) were positive for IgM antibody against HEV, establishing hepatitis E virus responsible for the outbreak. Significant association of higher attack rates (4%) in ward 14 (OR = 17.9...

The third instar larvae of the goldenrod gaIl fly, Eurosta solidugensis, overwinter inside stem galls on goldenrod plants and display a cold hardiness which allows the insects to survive prolonged freezing at temperatures as low as -30°C (17). A number of metabolic adjustments have been linked to the process of freezing tolerance in animals or frost hardiness in plants including: changes in amo...

We evaluated the cooling rate of hyperthermic subjects, as measured by rectal temperature (T(re)), during immersion in a range of water temperatures. On 4 separate days, seven subjects (4 men, 3 women) exercised at 65% maximal oxygen consumption at an ambient temperature of 39 degrees C until T(re) increased to 40 degrees C (45.4 +/- 4.1 min). After exercise, the subjects were immersed in a cir...

continuous availability of soil water is an important factor for plant growth. both lack of adequate access to water in soils, or adequate oxygen in saturated soils, may reduce or even stop plant growth. to study the behavior of pistachio seedling at various moisture levels and to determine non-limiting water range for its growth, a greenhouse experiment with a completely randomized design was ...

We became interested several years ago in exploring whether 14-helical beta-peptide foldamers could bind protein surfaces and inhibit protein-protein interactions, and if so, whether their affinities and specificities would compare favorably with those of natural or miniature proteins. This exploration was complicated initially by the absence of a suitable beta-peptide scaffold, one that posses...
