Wheat Extract Oil (WEO) Attenuates UVB-Induced Photoaging via Collagen Synthesis in Human Keratinocytes and Hairless Mice.

The efficacy of wheat extract oil (WEO), standardized to glucosylceramides, for protecting against ultraviolet B (UVB)-induced damage of skin barrier function was assessed using the SHK-1 hairless mouse model and two human skin cell lines, namely, CCD-986sk and HeCaT. The ability of repeated oral administration of 30, 60, and 120 mg of WEO/kg/day for 12 weeks to prevent skin damage of SKH-1 hairless mice induced by UVB irradiation was evaluated. The results demonstrated that UVB-induced water evaporation (transepidermal water loss, TEWL) was significantly decreased by WEO. Similarly, UVB-induced losses in moisture and skin elasticity were improved by WEO supplementation. WEO attenuated the tissue procollagen type I, hyaluronic acid (HA), and ceramide reductions induced by UVB treatment as well. Collagen concentrations in skin tissue were increased in the WEO-treated mice, while UVB-induced epidermal thickening was reduced. In vitro studies using HeCaT human keratinocytes confirmed increased HA and collagen synthesis in response to WEO treatment. This may occur via WEO suppression of matrix metallopeptidase-1 (MMP-1), since its induction by UVB treatment was diminished in treated CCD-986sk cells. Oral administration of WEO improves skin barrier function in UVB-irradiated mice by attenuating damage typically observed in photoaging. This research further clarifies the clinical benefits previously observed by dietary WEO consumption.

Efficacy of a novel herbal formulation for weight loss demonstrated in a 16-week randomized, double-blind, placebo-controlled clinical trial with healthy overweight adults.

AIM: To re-evaluate the weight loss efficacy of LI85008F in healthy overweight adults via a 16-week randomized, double-blind, placebo-controlled clinical study. MATERIALS AND METHODS: One hundred and forty overweight participants (body mass index [BMI] 27-29.9 kg/m2 , 29.3% male; ages 21-50 years) were randomized into placebo (n =70) and LI85008F (n =70) groups. The participants received either 900 mg/d of LI85008F in two divided doses or two identical placebo capsules. In addition, participants were counselled to follow an ~1800 kcal/d diet and to engage in walking for 30 min, 5 d/wk throughout the study. RESULTS: At the end of the trial period, the LI85008F supplemented group showed significant reductions in body weight (5.36 ± 1.769 vs. 0.87 ± 1.381 kg; P < 0.0001) and BMI (2.05 ± 0.693 vs. 0.34 ± 0.559 kg/m2 ; P < 0.0001), compared with placebo. Significant reductions in waist and hip circumferences, and a 2.08-fold reduction of waist/hip ratio, were noted in the LI85008F supplemented group. LI85008F supplementation also resulted in significant improvements in lipid profiles, compared with the placebo; low-density lipoprotein (LDL) cholesterol decreased, while high-density lipoprotein (HDL) cholesterol increased, resulting in a significantly improved LDL/HDL ratio. No major adverse events were reported by the participants during the study. CONCLUSIONS: The unique herbal extract blend LI85008F, combined with modest calorie restriction and physical activity, is well tolerated, safe, and effective for weight management in overweight men and women.

A Placebo-Controlled Double-Blind Study Demonstrates the Clinical Efficacy of a Novel Herbal Formulation for Relieving Joint Discomfort in Human Subjects with Osteoarthritis of Knee.

LI73014F2 is a novel composition prepared from extracts of Terminalia chebula fruit, Curcuma longa rhizome, and Boswellia serrata gum resin with synergistic benefit in 5-Lipoxygenase (5-LOX) inhibition. This herbal composition with strong anti-5-LOX activity exhibited significant pain relief as indicated through improvements in weight-bearing capacity in a monosodium iodoacetate-induced osteoarthritis (OA) model of Sprague-Dawley rats. A 90-day randomized, placebo-controlled double-blind study evaluates the clinical efficacy and tolerability of LI73014F2 in the management of symptoms of OA of the knee (Clinical Trial Registration No. CTRI/2014/01/004338). Subjects, (n = 105), were randomized into three groups: placebo (n = 35), 200 mg/day of LI73014F2 (n = 35), and 400 mg/day of LI73014F2 (n = 35). All study participants were evaluated for pain and physical function by using standard tools, that is, Visual Analog Scale, Lequesne's Functional Index, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at the baseline (day 0) and on day 14 ± 3, 30 ± 3, 60 ± 3, and at the end of the study (day 90 ± 3). In addition, routine examinations on biochemical parameters in serum, urine, and hematological parameters were conducted on each visit to assess the safety of the study material. At the end of the trial period, LI73014F2 conferred significant pain relief, improved physical function, and quality of life in OA patients. In conclusion, preclinical and clinical data together strongly suggest that the herbal formulation LI73014F2 is a safe and effective intervention for management of joint discomfort, demonstrating efficacy as early as 14 days.

The relationship between spirituality and compliance in patients with heart failure.

A high incidence of noncompliance to prescribed treatment plans results in increased morbidity, hospitalizations, and mortality rates in patients with heart failure. Exploration of new avenues to encourage adherence is needed in nursing research. The purpose of this study was to explore whether a relationship existed between spirituality and compliance in patients with heart failure. The Spiritual Assessment Scale and the Heart Failure Compliance Questionnaire Revised were mailed to a convenience sample with a return response from 95 participants. Although mean scores for the Spiritual Assessment Scale and the Heart Failure Compliance Questionnaire Revised were high, data suggested no correlation existed between levels of spirituality and degree of compliance among the heart failure participants, r=16393; p=0.115. Although insignificant results were found between levels of spirituality and degree of compliance, the data did not rule out the importance of spirituality as a coping tool.
