Libifem® (Trigonella foenum-graecum) in conjunction with exercise on muscle strength, power, endurance, and body composition in females aged between 25 and 45 years.

Introduction: This study examined the effects of Libifem® on exercise performance and body composition in females 25-45 years old. Methods: Participants were randomized to three equal groups to consume: 600 mg Libifem®/day, 300 mg Libifem®/day or a placebo for 8 weeks. Participants completed a whole-body exercise program three times a week for 8 weeks. At baseline, week 4 and week 8, muscle strength and endurance, functional threshold power, body composition, and sex hormones were measured. At week 8, all three groups increased leg press 1RM compared to baseline. Results: A significant difference between group treatment effect was seen for leg press at week 8 (p = 0.045), with the 600 mg Libifem® group significantly increasing their leg press 1RM compared to placebo (p = 0.014). The 600 mg Libifem® group significantly reduced their total fat mass (0.96 kg loss) from baseline compared to placebo group (0.09 kg gain). There was no significant difference in fat mass for the 300 mg Libifem® group (0.23 kg loss). The 600 mg Libifem® group had a significant increase in lean mass compared to both the 300 mg and placebo groups (p = 0.011 and 0.009, respectively). Discussion: Overall, there were significant and dose-related changes in body composition and ergogenic parameters, comparable with previous findings in males. Clinical Trial Registration: This trial was registered with the Australian and New Zealand Clinical Trials registry [ACTRN12618001538235].

Perspectives on Neuronutrition in Prevention and Treatment of Neurological Disorders.

The term neuronutrition has been proposed as part of nutritional neuroscience, studying the effects of various dietary components on behavior and cognition. Other researchers underline that neuronutrition includes the use of various nutrients and diets to prevent and treat neurological disorders. The aim of this narrative review was to explore the current understanding of the term neuronutrition as the key concept for brain health, its potential molecular targets, and perspectives of its nutritional approach to the prevention and treatment of Alzheimer's and Parkinson's diseases, multiple sclerosis, anxiety, depressive disorders, migraine, and chronic pain. Neuronutrition can be defined as a part of neuroscience that studies the influence of various aspects of nutrition (nutrients, diet, eating behavior, food environment, etc.) on the development of nervous disorders and includes nutrition, clinical dietetics, and neurology. There is evidence that the neuronutritional approach can influence neuroepigenetic modifications, immunological regulation, metabolic control, and behavioral patterns. The main molecular targets in neuronutrition include neuroinflammation, oxidative/nitrosative stress and mitochondrial dysfunction, gut-brain axis disturbance, and neurotransmitter imbalance. To effectively apply neuronutrition for maintaining brain health, a personalized approach is needed, which includes the adaptation of the scientific findings to the genetic, biochemical, psycho-physiological, and environmental features of each individual.

Palmitoylethanolamide: A Potential Alternative to Cannabidiol.

The endocannabinoid system (ECS) is a widespread cell signaling network that maintains homeostasis in response to endogenous and exogenous stressors. This has made the ECS an attractive therapeutic target for various disease states. The ECS is a well-known target of exogenous phytocannabinoids derived from cannabis plants, the most well characterized being Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD). However, the therapeutic efficacy of cannabis products comes with a risk of toxicity and high abuse potential due to the psychoactivity of THC. CBD, on the other hand, is reported to have beneficial medicinal properties including analgesic, neuroprotective, anxiolytic, anticonvulsant, and antipsychotic activities, while apparently lacking the toxicity of THC. Nevertheless, not only is the currently available scientific data concerning CBD's efficacy insufficient, there is also ambiguity surrounding its regulatory status and safety in humans that brings inherent risks to manufacturers. There is a demand for alternative compounds combining similar effects with a robust safety profile and regulatory approval. Palmitoylethanolamide (PEA) is an endocannabinoid-like lipid mediator, primarily known for its anti-inflammatory, analgesic and neuroprotective properties. It appears to have a multi-modal mechanism of action, by primarily activating the nuclear receptor PPAR-α while also potentially working through the ECS, thus targeting similar pathways as CBD. With proven efficacy in several therapeutic areas, its safety and tolerability profile and the development of formulations that maximize its bioavailability, PEA is a promising alternative to CBD.

The effect of an orally-dosed Gynostemma pentaphyllum extract (ActivAMP®) on body composition in overweight, adult men and women: A double-blind, randomised, placebo-controlled study.

BACKGROUND: The present study examined the effect of a herbal supplement containing a Gynostemma pentaphyllum (Gpp) extract (ActivAMP®) with respect to improving body composition in overweight males and females. METHODS: One-hundred and seventeen men and women aged over 18 years completed 16 weeks of daily supplementation with either Gpp or a placebo. Participants underwent dual-energy X-rays to assess body composition (fat mass, lean mass and mass distribution), as well as anthropometric measures (weight, height, hip and waist circumference), in addition to blood tests to assess inflammatory and safety markers. RESULTS: Following 16 weeks of treatment, the Gpp group had a significant reduction in total body weight, body mass index, total fat mass and gynoid fat mass compared to the placebo group. Blood measures showed plasma triglyceride, alanine aminotransferase and tumour necrosis factor-α to be statistically different between groups at week 16. Subgroup analysis of gender for fat distribution showed males in the Gpp group had a significant reduction in visceral fat compared to males in the placebo group and females in the Gpp group had a significant reduction in gynoid fat compared to the placebo group. CONCLUSIONS: Gpp was capable of altering fat mass and fat distribution in overweight and obese males and females compared to a placebo.

Palmitoylethanolamide: A Natural Compound for Health Management.

All nations which have undergone a nutrition transition have experienced increased frequency and falling latency of chronic degenerative diseases, which are largely driven by chronic inflammatory stress. Dietary supplementation is a valid strategy to reduce the risk and severity of such disorders. Palmitoylethanolamide (PEA) is an endocannabinoid-like lipid mediator with extensively documented anti-inflammatory, analgesic, antimicrobial, immunomodulatory and neuroprotective effects. It is well tolerated and devoid of side effects in animals and humans. PEA's actions on multiple molecular targets while modulating multiple inflammatory mediators provide therapeutic benefits in many applications, including immunity, brain health, allergy, pain modulation, joint health, sleep and recovery. PEA's poor oral bioavailability, a major obstacle in early research, has been overcome by advanced delivery systems now licensed as food supplements. This review summarizes the functionality of PEA, supporting its use as an important dietary supplement for lifestyle management.

Enzyme-Treated Zizania latifolia Ethanol Extract Protects from UVA Irradiation-Induced Wrinkle Formation via Inhibition of Lysosome Exocytosis and Reactive Oxygen Species Generation.

Ultraviolet A (UVA) is a risk factor for photoaging and wrinkle formation. Zizania latifolia is an herbaceous perennial plant. It contains many bioactive compounds such as tricin that show antioxidative and anti-inflammatory effects. The aim of this study was to investigate the antiwrinkle effect of a mixture of hydrolytic enzyme (cellulase, hemicellulase and pectinase)-treated Z. latifolia extract (ZLE) and tricin on UVA-irradiated human dermal fibroblasts (HDFs) and SKH-1 hairless mice. Treatment of UVA-irradiated HDF cells with ZLE and tricin significantly decreased UVA induced-plasma membrane rupture, generation of ROS, expression levels of total and secreted lysosomal associated membrane protein (LAMP-1), cathepsin B and metalloproteinases (MMPs) and inhibited NF-κB activation. In the animal study, UVA-damaged epidermal and dermal tissues were repaired by the ZLE and tricin treatments. Administration of ZLE or tricin to UVA-irradiated animals recovered skin surface moisture and collagen fiber in dermal tissue. Treatment of ZLE or tricin decreased wrinkle formation, secretion of MMPs and expression levels of vascular endothelial growth factor (VEGF) and cathepsin B, and increased the expression level of collagen-1 in UVA-irradiated animals. Overall, the ZLE and tricin treatments decreased the skin damage induced by UVA irradiation via inhibition of lysosomal exocytosis and ROS generation. Therefore, ZLE and tricin are promising as antiwrinkle and antiphotoaging agents.

Origins of the Arden Syntax.

The Arden Syntax originated in the 1980's, when several knowledge-based systems began to show promise, but researchers recognized the burden of recreating these systems at every institution. Derived initially from Health Evaluation through Logical Processing (HELP) and the Regenstrief Medical Record System (RMRS), the Arden Syntax defines medical logic that can be encoded as independent rules, such as reminders and alerts, with the hope of creating a public library of rules. It was first vetted at an informatics retreat held in 1989 at Columbia University's Arden Homestead. The syntax was intended to be readable by clinician experts but to provide powerful array processing, which was derived largely a programming language called APL. The syntax was improved and implemented by a number of researchers and vendors in the early 1990's and was initially adopted by the consensus standards organization, the American Society for Testing and Materials.

affron® a novel saffron extract (Crocus sativus L.) improves mood in healthy adults over 4 weeks in a double-blind, parallel, randomized, placebo-controlled clinical trial.

BACKGROUND: In recent years phytotherapy has been explored as a source for alternative treatments for mood disorders. One potential candidate is saffron (Crocus sativus L.), whose main bioactive components are crocins and safranal. OBJECTIVES: The aim of this study was to investigate the efficacy of affron®, a standardised stigmas extract from Crocus sativus L. for improving mood, stress, anxiety and sleep quality in healthy adults. METHODS: In this 3 arm study, 128 participants self-reporting low mood but not diagnosed with depression, were given affron® at 28mg/day, 22mg/day, or a placebo treatment in a randomized, double-blind, placebo-controlled trial for 4 weeks. Mood was measured at baseline and at the end of the study, using the POMS (primary outcome measure) and PANAS questionnaires, and the DASS-21 scale. Sleep was monitored using Sleep Quality Index (PSQI). RESULTS: Analysis indicated a significant decrease in negative mood and symptoms related to stress and anxiety at a 28mg/day dose (with a significant difference between 28mg/day and placebo on the POMS Total Mood Disturbance scale, p<0.001, d=-1.10), but no treatment effect at the 22mg/day dose. LIMITATIONS: The main weaknesses of this investigation were found in the self-reporting nature of both the screening and the testing. CONCLUSIONS: affron® increased mood, reduced anxiety and managed stress without side effects, offering a natural alternative to standard treatments.

TNFα Variation During the Menstrual Cycle and Thereafter: A New Explanation for Gender-Based Disparities in ICU Admission Rates, Trauma Outcomes, and General Mortality.

BACKGROUND: Multiple studies have found gender-based disparities in intensive care unit (ICU) admission rates and in complications following trauma. Female gender was associated with lower mortality when comparing patients less than 50 years of age. These data suggest an important role for cycle rather than gender itself. Our previous results indicate a crucial role for tumor necrosis factor alpha (TNFα) in inducing nososocomial infections. HYPOTHESIS: Cycle is important for TNF and other female hormone productions. METHODS: Six older than 60 years old volunteers in both genders, 40 young female volunteers (no contraceptive drug, n = 18, contraceptive drug, n = 9, lactation, n = 9, pregnant, n = 4) were collected with following exclusion criteria, malignant disease, inflammation, infection, trauma and taking non-steroid anti-inflammatory drugs and antibiotics. Females were studied on days 1 and 14 of cycle. Serum TNFα was determined by HS TNF ELISA. Female hormones were also determined. RESULTS: Serum TNFα, estradiol, and progesterone individual values in volunteers with cycle (no contraceptive drug) demonstrate marked interindividual differences on day 1 and day 14 of cycle. It can be seen beside interindividual differences the personal difference between TNFα, estradiol, and progesterone values on day 1 and day 14.Serum TNFα, estradiol, and progesterone individual values in volunteers with no cycle (contraceptive drug yes) demonstrate marked interindividual differences on day 1 and day 14 of cycle. It can be seen beside interindividual differences the personal difference between TNFα, estradiol, and progesterone values on day 1 and day 14; furthermore, seemingly lower estradiol values on day 1 and day 14 between groups can be seen. A significant decrease was demonstrated in serum progesterone values on day 14 of group with contraceptive drug compared with group with no contraceptive one.A significant negative correlation is demonstrated between serum progesterone and serum TNFα values on day 14.A marked significant difference in serum TNFα values between volunteers with cycle and with no cycle, like contraceptive, lactation pregnancy (trimesters P1, P2, P3), and climax. CONCLUSION: For homogenous group of female patients not the gender and age are important but the cycle itself.

From alga to omega; have we reached peak (fish) oil?

SummaryWhile the Inuit diet was highly cardio-protective and consuming oily fish within a Western diet is to a lesser degree, the case for purified fish oil supplements is less convincing. Purification of fish oil removes lipophilic polyphenols which likely contribute to the health benefits of oily fish; leaving the ω3 highly unsaturated fatty acids exposed and prone to conferring oxidative and inflammatory stress. The authors believe that due to such issues as dietary shift, it may now be inadvisable to prescribe or sell purified ω3 highly unsaturated fatty acids supplements, unless the appropriate co-factors are included.

Alternative treatment of serious and mild Pasteurella multocida infection in New Zealand White rabbits.

BACKGROUND: Pasteurella multocida causes numerous economically relevant diseases in livestock including rabbits. Immunisation is only variably effective. Prophylactic antibiotics are used in some species but are contra-indicated in rabbits, due to their adverse effects on the rabbit microbiota. There is therefore a substantial need for alternative forms of infection control in rabbits; we investigated the effect of oral ß-glucan on P. multocida infection in this species. RESULTS: Thirthy-five New Zealand White rabbits were randomly divided into five groups of seven animals. Three groups were inoculated with Pasteurella multocida intranasally (in.), a physiologically appropriate challenge which reproduces naturally acquired infection, and received either (1-3), (1-6) ß-glucans or placebo. Four other groups were inoculated both in. and intramuscularly (im.), representing a supra-physiological challenge, and received either (1-3), (1-6) ß-glucans, antibiotic or placebo. ß-glucans given prophylactically were highly effective in protecting against physiological (in.) bacterial challenge. They were less effective in protecting against supra-physiological bacterial challenge (in. and im.), although they extended survival times. This latter finding has practical relevance to breeders as it extends the window in which heavily infected and symptomatic animals can be salvaged with antibiotics. CONCLUSIONS: In our study, (1-3), (1-6) ß-glucans were highly effective in protecting against a model of naturally acquired P. multocida infection and extended survival times in the supra-physiological model. Enrofloxacin was effective in protecting against supra-physiological infection. We are currently reviewing the use of combined prophylaxis.

Novel therapeutic strategies in infection and cancer management.

We are entering a post-antibiotic era in medicine, as resistance to commonly used antibiotics rises and the discovery of successful new classes of antibiotics slows. New therapeutic targets are being identified and investigated, including approaches that may overcome resistance, interrupt bacterial communication, and enhance human immune function. Immune function is negatively affected by type B malnutrition (multiple micronutrient depletion), "pathological hygiene" (removal of innate immune primers such as yeasts from the food chain), the removal of innate primers such as yeasts from the food chain, HIV infection, diabetes, chronic stress and depressive illness, and the use of immunosuppressant medications. These and other forms of innate immune dysfunction can be overcome / compensated for by novel therapeutic tools which enhance or mimic different aspects of innate immune function, and which re-configure and reinforce Claude Bernard's milieu interieur.

Antiobesogenic and Antiatherosclerotic Properties of Caralluma fimbriata Extract.

There is evidence that the principles present in the widely consumed Indian food plant C. fimbriata extract (CFE) suppress appetite, and provide antiobesogenic and metabolic benefits. The Diet-Induced Obesity (DIO) rat model was used to investigate CFE's anorexigenic effects. Rats were randomly divided into three groups: (i) untreated control (C), (ii) control for cafeteria diet (CA), and (iii) cafeteria diet fed + CFE treated. Rats in the test group received cafeteria diet and CFE from day one onwards. CFE was administered by gavage at three doses (25, 50, 100 mg/Kg BW per day) for 90 days. The antiobesogenic effects of CFE were evaluated by monitoring changes in feed intake, body weight, serum lipid and hormonal (leptin) profiles, fat pads, and liver weight. Antiatherosclerotic effects were measured by histology. CFE induced significant and dose-dependent inhibition of food intake, with dose-related prevention of gains in body weight, liver weight, and fat pad mass. Alterations in serum lipid profiles associated with weight gain were similarly inhibited, as were the typical increases in serum leptin levels. These data substantiate CFE's reported anorexigenic effects. CFE treatment also conferred protection against atherogenesis. We conclude that CFE possesses antiobesogenic and antiatherosclerotic properties.

How the mid-Victorians worked, ate and died.

Analysis of the mid-Victorian period in the U.K. reveals that life expectancy at age 5 was as good or better than exists today, and the incidence of degenerative disease was 10% of ours. Their levels of physical activity and hence calorific intakes were approximately twice ours. They had relatively little access to alcohol and tobacco; and due to their correspondingly high intake of fruits, whole grains, oily fish and vegetables, they consumed levels of micro- and phytonutrients at approximately ten times the levels considered normal today. This paper relates the nutritional status of the mid-Victorians to their freedom from degenerative disease; and extrapolates recommendations for the cost-effective improvement of public health today.
