The effect of pyridoxine (PN) supplementation on lymphocyte
responsiveness was investigated in 15 elderly volunteers (aged
65-81 years) by measuring lymphocyte proliferation to T and B cell
mitogens, lymphocyte subpopulations with monoclonal antibodies
(T3, T4, T8) and plasma pyridoxal 5'-phosphate (PLP) concentration
at pre-supplementation and after 1 and 2 months...
This investigation was conducted to determine the
effect of estrogen replacement therapy (ERT) on vitamin B-6
status of postmenopausal women. Nineteen postmenopausal
women served as subjects. Nine (54.7 + 4.7 years) were
taking ERT (experimental group); ten (56.8 + 2.3 years)
were not (control group). For three consecutive days,
subjects...
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
phospholipid...
The effect of vitamin B-6 (B-6) status on plasma fatty acids (FA) levels and lipid
metabolism was investigated in this metabolic study. Eight female subjects were fed for 28
days. For the first 7 days, they were fed a constant diet containing 2.10 mg of B-6. For the
rest of...
Aflatoxin B₁ (AFB₁,) is a potent liver carcinogen to a number
of animal species including rainbow trout (Salmo gairdneri).
Microsomal activation is required for the in vitro conversion of
AFB, to a reactive metabolite, thought to be the AFB₁,-2,3-oxide,
which will bind nucleic acids, produce toxicity, and cause mutagenesis.
Nucleic...
The primary purpose of this investigation was to characterize
the lipids of the spores and vegetative cells of Cl. botulinum. A
second purpose was to explore the possibility that lipids might serve
as a means of differentiating the chiefly proteolytic Cl. botulinum
type B from the nonproteolytic Cl. botulinum types...
The influence of evaporative cooling for delay of 'Bartlett' and
'Bosc' fruit bud development for frost avoidance was investigated.
Two mist systems, one in a mature pear orchard and the other in a
young pear hedgerow, delayed 'Bartlett' and 'Bosc' bloom up to 15 and
8 days respectively. A low...
There are several grape disorders that reduce fruit
set. One, millerandage, is from poor fertilization to
produce "hen and chicken" or small seedless berries; while
another, Coulure, is the failure of grape flowers to
develop into berries. A third one, inflorescence necrosis
(INec), is a disorder that should be in...
Growth, yield components and leaf area were evaluated on
'Starkspur Supreme Delicious' apple on nine rootstocks: MAC 24, EMLA
7, EMLA 26, OAR 1, MAC 9, 0.3, EMLA 9, M 9, and EMLA 27. Estimates of
planting density based on growth, estimates of leaf area based on
four independent variables...
