The enduring effects of abuse and related adverse experiences in childhood

MS R. F. Anda MD, FACP V. J. Felitti MD, +5 authors MS W. H. Giles MD
European Archives of Psychiatry and Clinical…
2005

Childhood maltreatment has been linked to a variety of changes in brain structure and function and stress–responsive neurobiological systems. Epidemiological studies have documented the impact of… (More)

A single-chip linear optical amplifier

D. A. Francis, S P Dijaili, J. D. Walker
OFC 2001. Optical Fiber Communication Conference…
2001

The performance of a new, single-chip linear optical amplifier (LOA) is compared to a semiconductor optical amplifier and an EDFA. Bit-error-rate measurements of the LOA show no power penalty in a 10… (More)

SIAMESE, a gene controlling the endoreduplication cell cycle in Arabidopsis thaliana trichomes.

J. D. Walker, Danny Oppenheimer, J Concienne, J. C. Larkin
Development
2000

Cell differentiation is generally tightly coordinated with the cell cycle, typically resulting in a nondividing cell with a unique differentiated morphology. The unicellular trichomes of Arabidopsis… (More)

Infant Killing, Wounding and Predation in Eulemur and Lemur

Amber L. Jolly, S. Caless, +7 authors T. Zafison
International Journal of Primatology
2004

Infant killing by primates is highly controversial. Sexual selection of infanticidal males has been disputed, especially for seasonally breeding species, in which death of an infant does not advance… (More)

Glomerular structure in type-1 (insulin-dependent) diabetic patients with normo- and microalbuminuria.

J. D. Walker, Clare Close, +4 authors R Osterby
Kidney international
1992

Kidney biopsies from 15 type-1 (insulin-dependent) diabetic patients with a range of albumin excretion (AER) were analyzed. Nine patients had normal AER, and six had microalbuminuria. Basement… (More)

Type 1 diabetes mellitus and Down's syndrome: prevalence, management and diabetic complications.

Amira Anwar, J. D. Walker, Brian M. Frier
Diabetic medicine : a journal of the British…
1998

Type 1 insulin-dependent, diabetes mellitus (Type 1 DM) is thought to be more prevalent in individuals with Down's syndrome. To ascertain the local prevalence of Type 1 DM in patients with Down's… (More)

Time-dependent changes in matrix metalloproteinase activity and expression during the progression of congestive heart failure: relation to ventricular and myocyte function.

F. G. Spinale, Modupe Coker, Chrystal Thomas, J. D. Walker, R. Mukherjee, Latha Hebbar
Circulation research
1998

The development of congestive heart failure (CHF) is associated with left ventricular (LV) dilation and myocardial remodeling. However, fundamental mechanisms that contribute to this remodeling… (More)

Patients evaluate their hospital care: a national survey.

Strategies employed to determine the acute aquatic toxicity of ethyl benzene, a highly volatile, poorly water-soluble chemical.

Lara Masten, Riccardo Boeri, J. D. Walker
Ecotoxicology and environmental safety
1994

Studies are described in which ethyl benzene (EB) was tested to determine its acute toxicity to three marine organisms, Atlantic silversides (Menidia menidia), mysid shrimp (Mysidopsis bahia), and… (More)

Allele-specific interactions between ttg and gl1 during trichome development in Arabidopsis thaliana.

J. C. Larkin, J. D. Walker, A C Bolognesi-Winfield, J. C. Gray, A. R. Hight Walker
Genetics
1999

Trichome development in Arabidopsis thaliana is a well-characterized model for the study of plant cell differentiation. Two genes that play an essential role in the initiation of trichome development… (More)
