Abstract
BACKGROUND: Anthocyanins have been shown to improve endothelial
function in animal models. However, whether these compounds have similar
beneficial effects in humans is largely unknown.
METHODS: In a short-term crossover study, 12 hypercholesterolemic
individuals were given oral anthocyanins (320 mg) isolated from berries or
placebo. Brachial artery flow-mediated dilation (FMD) was assessed before and
after the intervention. In a long-term intervention trial (12 weeks), 150
hypercholesterolemic individuals were given anthocyanins (320 mg/day, n = 75)
or placebo (n = 75), after which we measured FMD, plasma cGMP, and other
serum biomarkers. Another short-term intervention was conducted in the
presence of NO-cGMP inhibitors in 6 people and in a rat aortic ring model (n =
8).
RESULTS: Significant increases of FMD from 8.3% (0.6%) at baseline to 11.0%
(0.8%) at 1 h and 10.1% (0.9%) at 2 h were observed after short-term
anthocyanin consumption, concomitantly with increases of plasma anthocyanin
concentrations (P < 0.05). In the study participants who received long-term
anthocyanin intervention, compared with the control group, we observed
significant increases in the FMD (28.4% vs 2.2%), cGMP (12.6% vs -1.2%), and
HDL-cholesterol concentrations, but decreases in the serum soluble vascular
adhesion molecule-1 and LDL cholesterol concentrations (P < 0.05). The
changes in the cGMP and HDL cholesterol concentrations positively correlated
with FMD in the anthocyanin group (P < 0.05). In the presence of NO-cGMP
inhibitors, the effects of anthocyanin on endothelial function were abolished in
human participants and in a rat aortic ring model.
CONCLUSIONS: Anthocyanin supplementation improves endotheliumdependent vasodilation in hypercholesterolemic individuals. This effect involves
activation of the NO-cGMP signaling pathway, improvements in the serum lipid
profile, and decreased inflammation.

Abstract
Vaccinium is a genus of shrubs several of which, including cranberry,
lingonberry, and blueberry, produce edible fruit. Consumption of the fruit of
these plants and juices pressed from it has long been known to have healthful
effects. A number of functional compounds have been extracted from the fruits
and seeds of these plants. Anthocyanidins and related compounds have been
reported to possess antimicrobial, antioxidant, and anti-inflammatory properties.
Extracts of the fruits have been applied to the inhibition of non-enzymatic
glycosylation in anti-aging preparations. The oil of the cranberry seed is high in
antioxidants and is a source of omega-3, -6, and -9 fatty acids making it an
attractive cosmetics component. The inhibition of tumor growth, angiogenesis,
and metastasis by extracts of these fruits has been described. Extracts of the
plants have also been applied to the development of antimicrobial paints and
coatings. Here, we provide an overview of the wide range of applications
described for various compounds from and preparations of these plants and
survey the recent patents related to those applications.

Abstract
OBJECTIVE: The aim of this work was to highlight the effects and the possible
mechanisms of the action of blueberry polyphenols on the central nervous
system (CNS).
METHODS: An analysis was carried out, in a temporal order, of the most
important literature about this topic and the results have been correlated with
the beneficial and protective effects, mainly concerning the CNS.
DISCUSSION: Over the last 10 years an increasing scientific interest has
developed about polyphenols, which are very abundant in blueberries, as they
have been seen to produce favourable effects related to neuroprotection and
linked to a possible decrease of age-related cognitive and motor decline, as
shown by the improvement of such functions in animal models with a
supplemented diet. Such effects could not only be explained through a purely
antioxidant action but also through more complex mechanisms related to
inflammation, genic expression, and regulation of cell survival.
CONCLUSIONS: Despite the wealth of data from animal studies, there is a
relative lack of data concerning human beings, even if some positive results are
beginning to emerge. Therefore, blueberry polyphenols could become useful
pharmacological agents for various conditions including neurological diseases,
but further studies are still necessary to attain this objective.

Vaccinium macrocarpon: an interesting option for women with recurrent
urinary tract infections and other health benefits.

Abstract
AIM: To review the scientific publications concerning the clinical use and
mechanism of action of the North American cranberry (Vaccinium macrocarpon)
for women with recurrent urinary tract infections (UTI) and other health
conditions.
METHODS: This is a retrospective study of published information concerning
Vaccinium macrocarpon retrieved from a PubMed and individual searches.
RESULTS: Urinary tract infections are very common in women, cause
discomfort, and may aggravate other genitourinary conditions. The available
scientific information supports a clinical benefit of Vaccinium macrocarpon in the
prevention of recurrent UTI in women. There is a non-significant reduction of
UTI associated with Vaccinium macrocarpon treatment during pregnancy. A
group of proanthocyanidins (PAC) with A-type linkages have been isolated from
Vaccinium macrocarpon which inhibit P-fimbriae synthesis and induce a
bacterial deformation, on both antibiotic-susceptible and antibiotic-resistant
uropathogenic Escherichia coli. It is plausible that cranberry PAC prevent
bacteria from adhering to the uroepithelium of the bladder, thereby blocking the
ability of E. coli to infect the urinary mucosa.
CONCLUSION: Cranberry treatment is a safe, well-tolerated supplement that
does not have significant drug interactions. Although investigations are in the
early stages, experimental and preclinical studies suggest that cranberry
components may have other potential benefits, including anti-infective,
anticancer and antioxidant effects, which may be considered as positive for
different age-related conditions. In addition, cranberry components may induce
positive cardiovascular and metabolic changes, and may improve
neuropsychological activity. These effects warrant further clinical research to
better place the role of cranberry products for women.

LAST II: Differential temporal responses of macular pigment optical
density in patients with atrophic age-related macular degeneration to
dietary supplementation with xanthophylls.

Abstract
BACKGROUND: Age-related macular degeneration (ARMD) is the leading
cause of vision loss in aging Western societies. The objective of the Lutein
Antioxidant Supplementation Trial (LAST) was to determine whether specific
dietary interventions increased macular pigment optical density (MPOD) and
visual function in patients with atrophic ARMD. The current objective of LAST II
is to discern those specific characteristics that increase MPOD, i.e., that might
differentiate a responder from a nonresponder.
METHODS: The LAST study was a prospective, 12-month, randomized,
double-masked, placebo-controlled trial conducted at an urban midwestern
Veterans Administation Hospital from August 1999 to May 2001. Ninety patients
with atrophic ARMD entered the study and were assigned randomly to 1 of 3
groups. Patients in group 1 received 10 mg lutein; in group 2, 10 mg lutein in
combination with vitamins, minerals, and antioxidants; and in group 3,
maltodextrin placebo. Changes in macular MPOD over time were evaluated.
Characteristics potentially influencing MPOD included age, weight (body mass
index), initial baseline values of macular pigment, and combining xanthophylls
with other nutrients.
RESULTS: MPOD increased with supplementation and declined slightly without
supplementation (regression slopes not equal to zero in supplemented groups,
P < 0.02). The highest increases in MPOD over time occurred in patients with
lower baseline values of MPOD. Statistically significant increases in MPOD
density were observed in the lutein group for patients with baseline MPOD
<or=0.3 optical density units and up to 0.2 optical density units in the lutein plus
antioxidant group. Further analysis found that none of the subjects' eyes in the
lowest quartile of baseline MPOD were in the lowest quartile for change in
MPOD.
CONCLUSION: Noteworthy is the observation that those individuals with lowest
MPOD, and in greatest need of supplementation, were also most likely to
benefit from either the lutein or the lutein plus antioxidant supplementation. For
those individuals who responded to supplementation, their macular pigment
optical density had not ceased to increase at 12 months' duration of
supplementation. The inference is that if a deficiency in macular pigment optical
density is accurately diagnosed, effective interventions should be able to reestablish this prophylactic barrier.

Abstract
The purpose of this study was to examine the effect of creatine supplementation
on the cognitive performance of elderly people. Participants were divided into
two groups, which were tested on random number generation, forward and
backward number and spatial recall, and long-term memory tasks to establish a
baseline level. Group 1 (n = 15) were given 5 g four times a day of placebo for 1
week, followed by the same dosage of creatine for the second week. Group 2 (n
= 17) were given placebo both weeks. Participants were retested at the end of
each week. Results showed a significant effect of creatine supplementation on
all tasks except backward number recall. It was concluded that creatine
supplementation aids cognition in the elderly.

Abstract
OBJECTIVE: The aim of this study was to evaluate the effects of isoflavones on
the skin of postmenopausal women.
DESIGN: A prospective study was performed with 30 postmenopausal women
before and immediately after the end of treatment with 100 mg/day of an
isoflavones-rich, concentrated soy extract for six months. A skin punch was
performed in the gluteal region for sample collection before and immediately
after the treatment program. Morphometric determination of epidermal
thickness, the papillary index (wrinkling), and the amount of dermal elastic and
collagen fibers was assessed. In addition, the number of blood vessels in the
sample was also evaluated. The paired Student's t-test was used for statistical
analysis (P < 0.05).
RESULTS: Isoflavone treatment resulted in a 9.46% increase in the thickness of
the epidermis in 23 patients. In addition, the papillary index was reduced in 21
women. The papillary index was inversely proportional to skin wrinkling, i.e.,
there were a large number of papillae after treatment. The amount of collagen in
the dermis was increased in 25 women (86.2%). In 22 women (75.8%) we
observed that the number of elastic fibers increased. The number of dermal
blood vessels was significantly increased in 21 women.
CONCLUSION: Our data show that the use of a concentrated, isoflavone-rich
soy extract during six consecutive months caused significant increases in
epithelial thickness, the number of elastic and collagen fibers, as well as the
blood vessels.

Abstract
The concentration of Vitamin E (vit E) and ubiquinone (CoQ10), which together
with squalene (SQ), play a key role against external oxidative insult, has been
shown to decrease significantly during ageing. The aim of the present study is
to inquire the effect of the combined use of topical bio-cosmetics containing
natural active principles (including sebum-like lipid fractions, sebum and
epidermal lipophilic and hydrophilic antioxidants), and oral antioxidant
supplements on the antioxidant content of sebum and stratum corneum. We
therefore treated the face and the back of 50 female volunteers aged 21-40,
daily for two months, with a base cream containing 0.05% ubiquinone, 0.1% vit
E, and 1% squalene. In addition 50 mg of CoQ10 + 50 mg of d-RRR-alphatocopheryl acetate + 50 microg of selenium were administered orally to half of
the volunteers (Group A). Group B was represented by 25 volunteers who were
treated only topically. Every 15 days during treatment the levels of CoQ10, vit E
and SQ were verified in sebum, stratum corneum, and plasma. The daily topical
application of the cream led to a significant increase, that peaked after 60 days,
of the levels of CoQ10, d-RRR-alpha-tocopherol and SQ in the sebum (Group
B), without significantly affecting the stratum corneum or plasma concentrations
of the redox couple CoQ10H2/CoQ10 and vit E. The concomitant oral
admistration of antioxidants produced in Group A a significant increase of the
levels of CoQ10H2/CoQ10 and vit E both in plasma and stratum corneum after
15 and 30 days treatment respectively, compared to Group B. However the
sebum levels of lipophilic antioxidants and SQ did not show a significant
increase. After the treatments, the levels of CoQ10H2/CoQ10, vit E and SQ
went back to basal levels within 6-8 days in sebum, 12-16 days in the stratum
corneum, and 3-6 days in plasma. Therefore topical application of the
antioxidants was able to increase their level in sebum, while the concomitant
oral administration also affected the levels of vit E and CoQ10 in the stratum
corneum.

Abstract
Insulin resistance is implicated in the pathophysiological changes associated
with Alzheimer's disease, and pharmaceutical treatments that overcome insulin
resistance improve memory function in subjects with mild cognitive impairment
(MCI) and early Alzheimer's disease. Chromium (Cr) supplementation improves
glucose disposal in patients with insulin resistance and diabetes. We sought to
assess whether supplementation with Cr might improve memory and neural
function in older adults with cognitive decline. In a placebo-controlled, doubleblind trial, we randomly assigned 26 older adults to receive either chromium
picolinate (CrPic) or placebo for 12 weeks. Memory and depression were
assessed prior to treatment initiation and during the final week of treatment. We
also performed functional magnetic resonance imaging (fMRI) scans on a
subset of subjects. Although learning rate and retention were not enhanced by
CrPic supplementation, we observed reduced semantic interference on
learning, recall, and recognition memory tasks. In addition, fMRI indicated
comparatively increased activation for the CrPic subjects in right thalamic, right
temporal, right posterior parietal, and bifrontal regions. These findings suggest
that supplementation with CrPic can enhance cognitive inhibitory control and
cerebral function in older adults at risk for neurodegeneration.

Abstract
Patients with type 2 diabetes are at considerable risk of excessive morbidity and
mortality from cardiovascular disease (CVD). We investigated the clinical
effectiveness of Pycnogenol, a flavonoid-rich dietary supplement, in reducing
antihypertensive medication use and CVD risk factors in subjects with type 2
diabetes. Forty-eight individuals were enrolled in a randomized, double-blind,
placebo-controlled trial with parallel-group design. Patients were diagnosed with
both type 2 diabetes and mild to moderate hypertension and were undergoing
treatment with angiotensin-converting enzyme (ACE) inhibitors. Subjects were
randomly assigned to receive either Pycnogenol pill (125 mg daily) or matched
placebo for 12 weeks. According to the values of blood pressure (BP) measured
at 2-week intervals, the pretrial ACE inhibitor dosage was left unchanged,
reduced by 50%, or brought back to the pretrial dosage until a stable BP was
obtained. Fasting plasma glucose, low-density lipoprotein (LDL) cholesterol,
glycosylated hemoglobin (HbA1c), serum endothelin-1, and urinary albumin
were evaluated monthly. Pycnogenol treatment achieved BP control in 58.3% of
subjects at the end of the 12 weeks with 50% reduction in individual pretrial
dose of ACE-inhibitors (P <.05). Plasma endothelin-1 decreased by 3.9 pg/mL
in Pycnogenol-treated group vs 0.5 pg/mL increase in control group (P < .001).
Mean HbA1c dropped by 0.8% in Pycnogenol-treated group (P < .05), whereas
it decreased by 0.1% in control group. Fasting plasma glucose declined by 23.7
mg/dL in Pycnogenol-treated group vs 5.7 mg/dL in control group (P < .0001).
Low-density lipoprotein cholesterol improved significantly in Pycnogenol-treated
group, declining by 12.7 mg/dL (P < .001). A significant decrease in urinary
albumin level was observed at week 8 compared with the control group (P <
.05). However, this reduction was not significant at 12th week. After 12 weeks of
supplementation, Pycnogenol resulted in improved diabetes control, lowered
CVD risk factors, and reduced antihypertensive medicine use vs controls.
