Severe deep white matter lesions and outcome in elderly patients with major depressive disorder: follow up study

Objective To determine the difference in outcome among elderly people with major depression who do and do not have severe white matter lesions on magnetic resonance imaging.

Turgor Regulation via Cell Wall Adjustment in White Spruce1

Turgor regulation at reduced water contents was closely associated with changes in the elastic quality of the cell walls of individual needles and shoots of naturally drought-resistant seedlings of white spruce (Picea glauca [Moench] Voss.) and of seedlings of intermediate resistance that had been pretreated with paclobutrazol, a stress-protecting, synthetic plant-growth regulator. Paclobutrazol-treated seedlings showed marked increases in drought resistance, and pressure-volume analysis combined with Chardakov measurements confirmed observations that water stress was ameliorated during prolonged drought. Turgor was maintained in the paclobutrazol-treated and in the naturally resistant drought-stressed seedlings despite water contents near or below the turgor-loss volumes of well-watered controls. The maintenance of turgor in these seedlings was in large part a function of the dynamic process of cell wall adjustment, as reflected by marked reductions in both the saturated and turgor-loss volumes and by large increases in the elastic coefficients of the tissues. Shear and Young's moduli, calculated from pressure-volume curves and the radii and wall thicknesses of mesophyll cells, also confirmed observed changes in the elastic qualities of the cell walls. Elastic coefficients of well-watered, paclobutrazol-treated seedlings were consistently larger than those in well-watered controls and several times larger than the values in untreated plants, which succumbed rapidly to drought. In contrast, untreated seedlings that withstood prolonged drought without wilting displayed elastic coefficients similar to those in seedlings that had been treated with paclobutrazol but that had not been exposed to drought.

Mortal: A Mutant of White Clover Defective in Nodal Root Development

A monogenic dominant mutant of white clover (Trifolium repens L.), designated Mortal, which is defective in the formation of adventitious nodal roots, is described. Mortal plants grown at temperatures ranging from 10 to 25°C do not initiate nodal root primordium development. However, all other aspects of plant development are normal, including the formation of lateral roots and wound-induced adventitious roots. In some genetic backgrounds, the Mortal mutation has a temperature-sensitive conditional phenotype. Mortal plants shifted from growing conditions of 20 to 30°C for 2 to 3 d form nodal root meristems. However, new nodes that develop after plants are returned to 20°C exhibit the mutant phenotype. The capacity to form nodal roots on cuttings placed in water is also influenced by the genetic background of the Mortal mutation. Genetic analysis established that the physiological reversion of Mortal to nodal root formation is controlled by at least two separate dominant genetic loci, one for Nodal water response (Now) and one for Nodal temperature response (Not); the Now locus has a dominant epistatic interaction with the Not locus. The conditional nature of Mortal should provide opportunities for the identification of genetic and physiological mechanisms that influence the development of nodal roots.

Arguments prepared by Daniel Appleton White for meetings of Phi Beta Kappa, 1796-1797

Three handwritten arguments prepared by Phi Beta Kappa member Daniel Appleton White (1776-1861; Harvard AB 1797) for discussion at meetings of the Alpha chapter at Harvard University in 1796 and 1797. The documents consist of a small paper notebook with a response to the prompt, "Whether the deeper studies, such as metaphysics, mathematics & natural philosophy, are entitled to our chief attention?" dated September 27, 1796, and prepared for debate with classmate Isaac Wellington (died 1797); a one-leaf document with a disputation on, "Whether civilized nations have a right to drive uncivilized nations from the lands they occupy?" dated December 8, 1796; and a small paper notebook containing White’s argument to the prompt, "Would a national university be beneficial for America?" that he debated with John Collins Warren (1778-1856; Harvard AB 1797) during the chapter’s May 16, 1797, meeting.

Subjects suggested by John Webster, 1826 July

A handwritten letter with suggested subjects from John White Webster, a lecturer of chemistry, mineralogy, and geology at the Harvard Medical College from 1824 until 1827, when he was appointed the Erving Professor of Chemistry (1827-1850).

Annotated almanac, 1755

Almanac containing calendar pages with sporadic annotations of measurements and small one-word notes. Winthrop often corrected the almanac's printed chart for the rising and setting of the sun. There are a few handwritten entries including a note in Latin about Winthrop's mother. An unattached sheet of paper folded into the almanac has burial and baptism statistics for Boston and Charleston, and entries about General Braddock's defeat by the French (July 9), a battle between General Johnson and the French and Indians under the Baron de Dieskau (September 8), the execution of two slaves for murdering their master (September 18), and a note that President Holyoke preached the Dudleian lecture (November 25).
