THE TRANSITION FROM FILAMENTOUS TO TWO-DIMENSIONAL GROWTH IN FERN GAMETOPHYTES. IV. INITIAL EVENTS
Autor: Bill D. Davis, Mary Philpott, James C. W. Chen
Publikováno v: American Journal of Botany. 61:722-729
A B S T R A C T Time-lapse photomicrography and autoradiography were used to study the initial events leading to the first cell division following transfer from red to white light. The first responses to white light, an apical swelling and a reduced

Diagnosis of dementia in cancer patients
Autor: Joel K. Levy, Douglas Lewis, Valerie F. Holmes, James Neidhart, Francisco Fernandez, Bill D. Davis, Frank Adams
Publikováno v: Psychosomatics. 28:175-179
Among 61 cancer patients referred for neuropsychiatric consultation, 43 (71%) had an organic mental disorder, and in 11 patients the disorder was consistent with dementia. Three of these cases are described in some detail to discuss the possible etio

GROWTH OF EXCISED PEA EMBRYONIC AXES ON DIFFERENT SUGARS
Autor: Bill D. Davis
Publikováno v: American Journal of Botany. 70:816-820
Excised pea embryonic axes were cultured on mineral salts plus various carbon sources. Growth continued for at least 3 wk, as measured by increased length, fresh and dry wt, sugar content, and f-amylase activity. The optimum sucrose concentration for

Determining Enzyme Activity by Radial Diffusion
Autor: Bill D. Davis
Publikováno v: The American Biology Teacher. 39:217-226
B ESIDES BEING OF INTEREST IN THEMSELVES, enzymes are useful markers of such diverse biological processes as differentiation, physiology, metabolism, genetics, and evolution. Enzymes are assayed to monitor food processing and are important in clinica

EFFECTS OF SUGARS ONα-AMYLASE ACTIVITY IN PEA EMBRYONIC AXES
Autor: Bill D. Davis
Publikováno v: American Journal of Botany. 70:821-826
Several methods were used to test the hypothesis that a-amylase activity in pea stem tissues is regulated by catabolite repression. The presence of various exogenous sucrose concentrations had little effect upon the accumulation and subsequent loss o

THE TRANSITION FROM FILAMENTOUS TO TWO-DIMENSIONAL GROWTH IN FERN GAMETOPHYTES. II. KINETIC STUDIES ON PTERIDIUM AQUILINUM
Autor: Bill D. Davis
Publikováno v: American Journal of Botany. 56:1048-1053
Gametophytes of the fern Pteridium aquilinum were incubated 3 days in red light and then transferred to white light. The sequence of events occurring after the transfer was as follows: a swelling of the apical region within 1 hr; a reduction in cell
