    Full Text Available Cyclosporine (CyA is a well-known immunosuppressant with a narrow therapeutic window. Its bioavailability is affected by many other traditional drugs and herbal extracts. Cytochrome P-450 isoenzymes CYP3A4 and CYP3A5 and protein P-glycoprotein (P-gp are involved in CyA bioavailability. Interactions of CyA with herbal extracts are not well known, but, given their increased concomitant use, it is important to know which extracts, many of which are commonly self-prescribed, can affect CyA blood concentrations. Decreased CyA blood concentration has been shown with St John’s wort in case reports and, in vivo animal studies, with ginger, liquorice, scutellariae radix, and quercetin. Increased CyA concentration has been reported in patients with grapefruit juice, chamomile, or berberine, and with cannabidiol or resveratrol in animal studies. Effects of Echinacea and Serenoa repens on CyA levels have not been shown consistently, but concomitant use should be avoided. Although findings from animal studies cannot be directly translated into humans, avoiding concomitant use of herbal extracts is prudent until human clinical studies have ruled out any possible interaction. Clinicians should interview their patients carefully about their use of herbal supplements before CyA administration, and those receiving CyA should be warned about possible interactions between herbal preparations and CyA.

    2009-11-01

    Herbal and dietary supplements (HDS) are commonly used in the United States and throughout the world. The Dietary Supplement Health and Education Act and public standards set through the U.S. Pharmacopeia provide regulatory framework for these products. These regulations help to ensure the safety of grandfathered and new HDS coming onto the market, and the opportunity to identify and take action against unsafe products that have been distributed. The clinical patterns of presentation and severity of HDS-associated hepatotoxicity can be highly variable, even for the same product. In addition, accurate causality assessment in cases of suspected HDS hepatotoxicity is confounded by infrequent ascertainment of product intake by healthcare providers, under-reporting of HDS use by patients, the ubiquity of HDS and the complexity of their components, and the possibility for product adulteration. Additional measures to prevent HDS-induced hepatotoxicity include greater consumer and provider awareness, increased spontaneous reporting, and reassessment of regulations regarding the manufacturing, distribution, and marketing of these products.

    The use of natural supplements, included herbal supplements, by athletes has become an habit which often lacks any valid scientific rationale. It appears evident that this habit may entail health risks (including more or less serious adverse effects), consequent either: 1) to the pharmacodynamic effects of the drugs at high doses; or 2) to the occurrence of accumulation especially when their administration is not justified by a reduced synthesis or an increased demand; or 3) to the occurrence of intolerance; or, finally, 4) to the presence of unlabelled ingredients. The abuse of this kind of products always entails risks to the consumer, not only to the elite athlete, that can incur an adverse analytical finding on the occasion of anti-doping tests, but also to the amateur sportsman, for the possible occurrence of adverse drug reactions (ADR).

    We report three cases of patients with acute liver injury induced by weight-loss herbal supplements. One patient took Hydroxycut while the other two took Herbalife supplements. Liver biopsies for all patients demonstrated findings consistent with drug-induced acute liver injury. To our knowledge, we are the first institute to report acute liver injury from both of these two types of weight-loss herbal supplements together as a case series. The series emphasizes the importance of taking a cautious approach when consuming herbal supplements for the purpose of weight loss.

    Herbal and dietary supplements (HDS) are used increasingly both in the United States and worldwide, and HDS-induced liver injury in the United States has increased proportionally. Current challenges in the diagnosis and management of HDS-induced liver injury were the focus of a 2-day research symposium sponsored by the American Association for the Study of Liver Disease and the National Institutes of Health. HDS-induced liver injury now accounts for 20% of cases of hepatotoxicity in the United States based on research data. The major implicated agents include anabolic steroids, green tea extract, and multi-ingredient nutritional supplements. Anabolic steroids marketed as bodybuilding supplements typically induce a prolonged cholestatic but ultimately self-limiting liver injury that has a distinctive serum biochemical as well as histological phenotype. Green tea extract and many other products, in contrast, tend to cause an acute hepatitis-like injury. Currently, however, the majority of cases of HDS-associated liver injury are due to multi-ingredient nutritional supplements, and the component responsible for the toxicity is usually unknown or can only be suspected. HDS-induced liver injury presents many clinical and research challenges in diagnosis, identification of the responsible constituents, treatment, and prevention. Also important are improvements in regulatory oversight of nonprescription products to guarantee their constituents and ensure purity and safety. The confident identification of injurious ingredients within HDS will require strategic alignments among clinicians, chemists, and toxicologists. The ultimate goal should be to prohibit or more closely regulate potentially injurious ingredients and thus promote public safety. (Hepatology 2017;65:363-373).

    Ginkgo biloba L. (known as ginkgo or maidenhair tree) is a phylogenetically isolated, charismatic, gymnosperm tree. Herbal dietary supplements, prepared from G. biloba leaves, are consumed to boost cognitive capacity via improved blood perfusion and mitochondrial function. A novel DNA mini-barcode assay was designed and validated for the authentication of G. biloba in herbal dietary supplements (n = 22; sensitivity = 1.00, 95% CI = 0.59-1.00; specificity = 1.00, 95% CI = 0.64-1.00). This assay was further used to estimate the frequency of mislabeled ginkgo herbal dietary supplements on the market in the United States of America: DNA amenable to PCR could not be extracted from three (7.5%) of the 40 supplements sampled, 31 of 37 (83.8%) assayable supplements contained identifiable G. biloba DNA, and six supplements (16.2%) contained fillers without any detectable G. biloba DNA. It is hoped that this assay will be used by supplement manufacturers to ensure that their supplements contain G. biloba.

Experimental design included three modifications of DNA extraction, two lysate dilutions, Internal Amplification Control, and multiple negative controls to exclude background contamination. Ginkgo supplements were also analyzed using HPLC-MS for the presence of active medicinal components.All supplements yielded DNA from multiple species, rendering Sanger sequencing results for rbcL and ITS2 regions either uninterpretable or non-reproducible between the experimental replicates. Overall, DNA from the manufacturer-listed medicinal plants was successfully detected in seven out of eight dry herb form supplements; however, low or poor DNA recovery due to degradation was observed in most plant extracts (none detected by Sanger; three out of seven-by NGS. NGS also revealed a diverse community of fungi, known to be associated with live plant material and/or the fermentation process used in the production of plant extracts. HPLC-MS testing demonstrated that Ginkgo supplements with degraded DNA contained ten key medicinal components.Quality control of herbal supplements should utilize a synergetic approach targeting both DNA and bioactive components, especially for standardized extracts with degraded DNA. The NGS workflow developed in this study enables reliable detection of plant and fungal DNA and can be utilized by manufacturers for quality assurance of raw plant materials, contamination control during the production process, and the final product.

    2007-11-01

    Within the last decade there has been a dramatic increase in the sale and use of herbal supplements and food supplements by Western populations and within the UK. This increased usage has coincided with a resurgence of interest in nutritional therapy and complementary and alternative medicine (CAM) therapies, such as herbal medicine, naturopathy and homeopathy, in which therapists may provide dietary advice and advocate the use of food or herbal supplements. The rise in the use of CAM therapies by the UK population can be attributed to several factors, including: promotion via health programmes and the media; a change in public attitudes; training of more nutritional and CAM therapists as a result of the increased availability of courses; a greater use of CAM and food and herbal supplements, particularly by patients with cancer. The aim of the present paper is to identify the pattern of usage of food and herbal supplements in the UK.

    Introduction The aim of the study was to estimate potential availability of essential oil in some brands of herbal products. Methods A comparison was performed on the basis of the essential oil yield in the unprocessed raw materials such as leaves of peppermint and lemon balm and inflorescence of chamomile as well as herbal tea bags and in dietary supplements. The yield of essential oil was determined by distillation. Essential oil was analyzed by GC-FID and GC-MS. Results It was found that the average potential availability of essential oils in the products such as dietary supplements for the doses recommended by the producers is lower than in the corresponding tea infusions: for peppermint formulations approximately 6-fold lower, for the formulations with lemon balm about 4-fold lower, and for the chamomile preparations about 3-fold lower. It was found that essential oils extracted from herbal teas have a similar chemical profile with characteristic deviations in the amount of individual components, which arise from the origin of the raw material. Discussion In contrast to homogenous pharmaceutical herbal mixtures consistent with, the Pharmacopoeia requirements, herbal teas (available in grocery stores) and dietary supplements are often out of control in terms of the yield and composition of the essential oil, which is primarily responsible for the health benefits and aromatic qualities of these products. Analysis of the composition of the dietary supplements showed that they contain on average significantly lower amounts of plant material compared to the herbal teas. PMID:26110869

    Dietary supplement use is common in the United States. Some herbal supplements may cause coagulopathy, hypertension, or dry eyes. The goal of this study is to reveal the incidence of herbal supplement use in the cosmetic surgery population. A retrospective chart review of 200 patients undergoing facial cosmetic surgery performed by a single surgeon was performed. Variables studied included patient age, sex, surgical procedure, herbal medication use, and intraoperative variables. Exclusion criteria were age younger than 15 years, noncosmetic procedures such as trauma, and incomplete preoperative medication form. Patients were subdivided into the supplement user group (herbal) and the supplement nonuser group (nonherbal). Statistical analysis included descriptive statistics, t test, and chi-square analysis. The incidence of supplement use was 49 percent in the 200 patients; 24.5 percent of patients used only vitamins or minerals, 2.5 percent of patients used only animal- and plant-based (nonvitamin/mineral) supplements, and 22 percent of patients used both types of supplements. In the herbal group, patients used an average of 2.8 supplements. The herbal and nonherbal groups differed significantly in sex (herbal, 89.8 percent female; nonherbal, 77.5 percent; p cosmetic surgery population, especially in the older female population. Considering the potential ill effects of these products on surgery and recovery, awareness and careful documentation and prohibiting the patients from the consumption of these products will increase the safety and reduce the recovery following cosmetic procedures.

    Herbal weight-loss supplements are marketed with claims of effectiveness. Our earlier systematic review identified data from double-blind, randomized controlled trials for a number of herbal supplements. The aim of this systematic review was to assess all clinical evidence of adverse events of herbal food supplements for body weight reduction for which effectiveness data from rigorous clinical trials exist. We assessed Ephedra sinica, Garcinia cambogia, Paullinia cupana, guar gum, Plantago psyllium, Ilex paraguariensis and Pausinystalia yohimbe. Literature searches were conducted on Medline, Embase, Amed and The Cochrane Library. Data were also requested from the spontaneous reporting scheme of the World Health Organization. We hand-searched relevant medical journals and our own files. There were no restrictions regarding the language of publication. The results show that adverse events including hepatic injury and death have been reported with the use of some herbal food supplements. For herbal ephedra and ephedrine-containing food supplements an increased risk of psychiatric, autonomic or gastrointestinal adverse events and heart palpitations has been reported. In conclusion, adverse events are reported for a number of herbal food supplements, which are used for reducing body weight. Although the quality of the data does not justify definitive attribution of causality in most cases, the reported risks are sufficient to shift the risk-benefit balance against the use of most of the reviewed herbal weight-loss supplements. Exceptions are Garcinia cambogia and yerba mate, which merit further investigation.

    2015-06-01

    Herbal and dietary supplements (HDS) have been used for health-related purposes since more than 5000 years, and their application is firmly anchored in all societies worldwide. Over last decades, a remarkable renaissance in the use of HDS can be noticed in affluent societies for manifold reasons. HDS are forms of complementary and alternative medicines commonly used to prevent or treat diseases, or simply as a health tonic. Another growing indication for HDS is their alleged benefit for weight loss or to increase physical fitness. Access is easy via internet and mail-order pharmacies, and their turnover reaches billions of dollars in the USA and Europe alone. However, HDS are generally not categorized as drugs and thus less strictly regulated in most countries. As a result, scientific evidence proving their beneficial effects is mostly lacking, although some HDS may have purported benefits. However, the majority lacks such proof of value, and their use is predominantly based on belief and hope. In addition to missing scientific evidence supporting their use, HDS are typically prone to batch-to-batch variability in composition and concentration, contamination, and purposeful adulteration. Moreover, numerous examples of preparations emerged which have been linked to significant liver injury. These include single ingredients, such as kava, germander, and several Chinese herbals. Other HDS products associated with liver toxicity consist of multiple, often ill-defined ingredients, such as Hydroxycut and Herbalife. Affirmative diagnostic tests are not available, and the assessment of liver injury ascribed to HDS depends on a thorough and proactive medical history, careful exclusion of other causes, and a search for available reports on similar events linked to the intake of the suspected preparation or ingredients contained therein.

    Purpose: This study was carried out in order to find a reliable method for the fast detection of adulterated herbal food supplements with sexual enhancement claims. As some herbal products are advertised as "all natural", their "efficiency" is often increased by addition of active pharmaceutical ingredients such as PDE-5 inhibitors, which can be a real health threat for the consumer. Methodes: Adulterants, potentially present in 50 herbal food supplements with sexual improvement claims, were detected using 2 spectroscopic methods - Raman and Fourier Transform Infrared - known for reliability, reproductibility, and an easy sample preparation. GC-MS technique was used to confirm the potential adulterants spectra. Results: About 22% (11 out of 50 samples) of herbal food supplements with sexual enhancement claims analyzed by spectroscopic and spectrometric methods proved to be "enriched" with active pharmaceutical compounds such as: sildenafil and two of its analogues, tadalafil and phenolphthalein. The occurence of phenolphthalein could be the reason for the non-relevant results obtained by FTIR method in some samples. 91% of the adulterated herbal food supplements were originating from China. Conclusion: The results of this screening highlighted the necessity for an accurate analysis of all alleged herbal aphrodisiacs on the Romanian market. This is a first such a screening analysis carried out on herbal food supplements with sexual enhancement claims.

  10. Herbal supplements and therapeutic drug monitoring: focus on digoxin immunoassays and interactions with St. John's wort.

    2008-04-01

    Herbal supplements can affect concentrations of therapeutic drugs measured in biological fluids by different mechanisms. Herbal products can either directly interfere with the methodology used in the measurement of drugs or indirectly interfere by altering the pharmacokinetics of coadministered drugs. The active components of Chan Su, Lu-Shen-Wan, Dan Shen, Asian and Siberian ginseng, oleander containing supplements, and Ashwagandha interfere with digoxin measurements by immunoassays, especially the polyclonal antibody-based immunoassays. Herbal supplements are sometimes contaminated with Western drugs causing drug toxicity. A therapeutic drug monitoring (TDM) service is very helpful for diagnosis of drug toxicity in such patients. Herbal products such as St. John's wort, a popular herbal antidepressant, increase the clearance of certain drugs either by increasing the activity of liver or intestinal cytochrome P-450 mixed-function oxidase or through modulation of the P-glycoprotein efflux pump. Significantly reduced concentrations of various therapeutic drugs such as digoxin, theophylline, cyclosporine, tacrolimus, tricyclic antidepressants, warfarin, and protease inhibitors can be observed due to interaction of these drugs with St. John's wort, causing treatment failure. On the other hand, a few drugs such as carbamazepine, mycophenolic acid, and procainamide do not show any interaction with St. John's wort. Understanding the effect of herbal products on TDM methodologies and identification of interactions between herbal products and drugs by TDM are very important clinically.

    2004-03-01

    The use of herbal products and other "natural" supplements among the US population is on the rise. Limited data suggest that such use among the elderly may correlate with higher education levels as well as psychiatric symptoms. The authors examined herbal/supplement use among elderly veterans with depression and/or dementia (n = 82) and their primarily elderly caregivers (n = 56). Eighteen percent of subjects and 16% of caregivers used herbals/supplements. Seventy-five percent of subjects who used these products during the study period were also taking potentially interacting medications. Given the prior association of herbal/supplement use with higher education levels, a surprising number of elderly veterans with depression and/or dementia (the majority of whom had high school or less education) used these products. As evidenced by missing documentation in many physician notes, subjects may not have discussed their usage of herbals/supplements with their physicians. In light of the possibility of potentially harmful drug interactions, physicians who treat elderly patients should regularly inquire about the use of these products.

    Herbal food supplements claiming to reduce weight may contain active pharmacological ingredients (APIs) that can be used for the treatment of overweight and obesity. The aim of this study was to determine whether herbal food supplements for weight loss on the Dutch market contain APIs with weight loss properties. Herbal food supplements intended for weight loss (n = 50) were sampled from August 2004 to May 2013. An HPLC-DAD-MS/MS method was used to screen for the presence of the APIs in herbal supplements. In 24 samples the APIs sibutramine, desmethylsibutramine (DMS), didesmethylsibutramine (DDMS), rimonabant, sildenafil and/or the laxative phenolphthalein were identified 41 times. The presence of these APIs was, however, not stated on the label. The potential pharmacological effects of the detected APIs were estimated using data from reported effective doses of approved drugs. Use of 20 of the 24 herbal food supplements may result in potential pharmacological effects. Furthermore, risk assessment of phenolphthalein, a suspected carcinogen and found to be present in 10 supplements, based on the margin of exposure (MOE) approach, resulted in MOE values of 96-30,000. MOE values lower than 10,000 (96-220) were calculated for the daily intake levels of four out of these 10 supplements in which phenolphthalein was found. However, taking into account that weight loss preparations may be used for only a few weeks or months rather than during a lifetime, MOE values may be two to three orders of magnitude higher. The current study shows that the use of food supplements with sibutramine, DMS, DDMS and/or phenolphthalein could result in pharmacological effects.

    Dental professionals routinely treat patients taking prescription, nonprescription, and herbal medications that are known or have the potential to alter bleeding. Prescription anticoagulant and antiplatelet medications, as well as over-the-counter drugs such as aspirin, are typically taken to reduce the risk of thromboembolic events, including stroke. Herbal supplements are widely used for a variety of indications, and both patients and health care practitioners are often unaware of the anticoagulant and antiplatelet effects that occur as either predictable pharmacologic effects or adverse side effects of herbal medicines. In addition, patient use of these herbal supplements is usually undisclosed to health care providers. The purpose of this literature review is to examine the mechanisms of action of drugs and herbs that alter bleeding, and to educate dental professionals as to the proper care and management of patients using these medications. Decision-making strategies, including interpretation of laboratory tests, and when to discontinue the use of these medications are discussed. Patients undergoing routine dental and dental hygiene procedures do not need to discontinue the use of anticoagulant and antiplatelet medications. However, alterations in drug use may be required for those patients undergoing invasive surgical procedures. It is recommended that herbal supplements must be discontinued 2 weeks prior to receiving invasive surgical procedures. Dental practitioners must learn to weigh the risks of discontinuing drug therapy against the potential risks to patients, and implement risk reduction strategies to minimize adverse bleeding complications associated with dental treatment.

    Full Text Available The study was conducted on Vencobb broiler chicks to ascertain the antistress affects of Zist, Zeetress and a combination of Amla and Turmeric during summer, rainy and winter seasons and thereby the haematological changes of birds revealed that during all the three seasons a marked improvement in Haemoglobin was encountered in all the three groups where herbal preparations were supplemented. A marked increase in the lymphocyte count occurred during summer and winter seasons in all the experimental groups of bird as compared to the control group. The heterophil count was decreased with the supplementation of herbal formulations in the feed irrespective of the seasons encountered in the season. This decrease in heterophil count was highly significant in seasons like summer, winter and rainy. This observation proves the hepato-stimulatory, hepato protective and immuno modulating effects of herbal preparations. [Veterinary World 2008; 1(4.000: 110-112

    Herbal medication in the United States is a popular form of therapy. This paper provides an overview of the utilization of herbal supplements with particular emphasis on possible interactions with oral health drugs and oral manifestations. Herbal supplements are regulated by the Dietary Supplement Health and Education Act (DSHEA), which limits their regulation by the U.S Food and Drug Administration (FDA). A number of studies indicate that there is a progressive increase in the utilization of herbal supplements. The majority of consumers of these products are white, middle-aged women who have some college education. Many of the consumers use pharmaceutical drugs concurrently, but most do not inform their health-care providers about their use of herbal supplements. Various herbal supplements have been reported or are suspected to interact with certain oral health drugs, the most important one being 1) bromelain, cayenne, chamomile, feverfew, dong quai, eleuthro/Seberian ginseng, garlic, ginkgo, ginger, ginseng and licorice interacting with aspirin; 2) aloe latex, ephedra, ginseng, rhubarb, cascara sagrada, licorice, and senna interacting with corticosteriods; 3) kava, St. John's wort, chamomile, and valerian interacting with central nervous system (CNS) depressant drugs; and 4) herbs acting on the gastrointestinal system, altering the absorption of several orally administered drugs. Further, the use of some herbal supplements has been reported to be associated with oral manifestations, including aphthous ulcers, lip and tongue irritation, and swelling with feverfew; gingival bleeding with feverfew and ginkgo; tongue numbness with echinacea; xerostomia with St. John's wort; oral and lingual dyskinesia with kava; and salivation with yohimbe. These potential effects of herbal supplements in conjunction with factors related to regulation restrictions suggest that the use of these products may be associated with various adverse reactions that can affect oral health and

    2015-06-28

    Herbal and dietary supplement usage has increased steadily over the past several years in the United States. Among the non-bodybuilding herbal and dietary supplements, weight loss supplements were among the most common type of HDS implicated in liver injury. While drug induced liver injury is rare, its consequences are significant and on the rise. The purpose of this review is to highlight case reports of weight loss products such as Hydroxycut and OxyElite Pro as one form of HDS that have hepatotoxic potential and to characterize its clinical effects as well as pattern of liver injury. We also propose future strategies in the identification and study of potentially hepatotoxic compounds in an effort to outline a diagnostic approach for identifying any drug induced liver injury.

    The adulteration of herbal supplements is of growing importance, especially when they contain undeclared compounds like sibutramine that are unsafe drugs. Sibutramine was withdrawn from US and European markets in 2010. In this study, an HPTLC-UV densitometric method was developed for the quantification of sibutramine in herbal diet foods. Sample extracts were directly applied onto HPTLC silica gel plates and separated with a mobile phase made of a toluene-methanol mixture. Sibutramine was quantified at 225 nm and its unequivocal identification was confirmed by MS using a TLC-MS interface. During two surveys, 52 weight loss supplements obtained via the Internet were screened. Half of those were adulterated with sibutramine at amounts reaching up to 35 mg per capsule. The results of this validated HPTLC method were compared with those obtained by HPLC-UV and HPLC-MS/MS. The results were not significantly different with the three methods.

    Erectile dysfunction (ED) is a sexual disorder characterized by the inability to achieve or maintain a sufficiently rigid erection. Despite the availability of non-invasive oral treatment options, many patients turn to herbal alternatives. Furthermore, herbal supplements are increasingly gaining popularity in industrialized countries and, as a consequence, quality control is a highly important issue. Unfortunately, this is not a simple task since plants are often crushed and mixed with other plants, which complicates their identification by usage of classical approaches such as microscopy. The aim of this study was to explore the potential use of chromatographic fingerprinting to identify plants present in herbal preparations intended for the treatment of ED. To achieve this goal, a HPLC-PDA and a HPLC-MS method were developed, using a full factorial experimental design in order to acquire characteristic fingerprints of three plants which are potentially beneficial for treating ED: Epimedium spp., Pausinystalia yohimbe and Tribulus terrestris. The full factorial design demonstrated that for all three plant references a C8 column (250mm×4.6mm; 5µm particle size) is best suited; methanol and an ammonium formate buffer (pH 3) were found to be the best constituents for the mobile phase. The suitability of this strategy was demonstrated by analysing several self-made triturations in three different botanical matrices, which mimic the influential effects that could be expected when analysing herbal supplements. To conclude, this study demonstrates that chromatographic fingerprinting could provide a useful means to identify plants in a complex herbal mixture.

    Full Text Available In view to study the role of herbal sources of essential amino acids in improving growth & performance, an experiment was conducted on seventy five day Vencob broiler chicks. Chicks were randomly divided into three groups (n=25, one negative control (T0 and two treatments (T1 & T2. Control group (T0 was offered basal diet deficient in natural or synthetic source of amino acids (choline, methionine, lysine & biotin. Treatment group T1 was fed with basal diet supplemented with polyherbal formulation comprising natural sources (herbs that mimic the activity of amino acids (choline, methionine, lysine & biotin @ 2Kg/tonne of feed while treatment group T2 was fed with basal diet supplemented with combination of synthetic choline chloride (600gm/tonne, synthetic methionine (1kg/tonne, synthetic lysine (1kg/tonne and biotin (150mg/tonne. Growth & performance parameters were recorded at weekly intervals and a metabolic trial for nutrient retention studies was conducted at the end of study. A significant increase in mean body weight gain, mean final body weight, feed efficiency & nutrient retention was observed in both the treated groups as compared to untreated control. The results of group T1 supplemented with herbal sources of amino acids were in confirmation with T2 supplemented with combination of synthetic amino acids suggesting that the polyherbal formula can successfully replace synthetic additives in feed.

    Herbal food supplements, claiming to enhance sexual potency, may contain deliberately added active pharmacological ingredients (APIs) that can be used for the treatment of erectile dysfunction (ED). The aim of this study was to determine whether herbal food supplements on the Dutch market indeed contain APIs that inhibit phosphodiesterase type 5 (PDE-5) inhibitors, such as sildenafil and analogous PDE-5 inhibitors. Herbal food supplements intended to enhance sexual potency (n = 71), and two soft drinks, were sampled from 2003 up to and including 2012. In 23 herbal supplements, nine different PDE-5 inhibitors were identified; in a few cases (n = 3), more than one inhibitor was indentified. The presence of these APIs was however not stated on the label. The concentrations of PDE-5 inhibitors per dose unit were analysed. Furthermore, the potential pharmacologically active properties of the detected PDE-5 inhibitors were estimated by using data from the scientific and patent literature regarding (1) in vitro PDE-5 activity, (2) reported effective doses of registered drugs with PDE-5 inhibitor activity and (3) similarity to other structural analogues. It was concluded that 18 of the 23 herbal food supplements, when used as recommended, would have significant pharmacological effects due to added APIs. Adequate use of existing regulation and control measures seems necessary to protect consumers against the adverse effects of these products.

    Full Text Available Antibiotic usage in animals as a growth promoter is considered as public health issue due to its negative impact on consumer health and environment. The present study aimed to evaluate effectiveness of herbal residue (ginger, Zingiber officinale, dried rhizome powder and prebiotic (inulin as an alternative to antibiotics by comparing fecal microflora composition using terminal restriction fragment length polymorphism. The grower pigs were offered feed containing antibiotic (tetracycline, ginger and inulin separately and un-supplemented group served as control. The study revealed significant changes in the microbial abundance based on operational taxonomic units (OTUs among the groups. Presumptive identification of organisms was established based on the fragment length of OTUs generated with three restriction enzymes (MspI, Sau3AI and BsuRI. The abundance of OTUs representing Bacteroides intestinalis, Eubacterium oxidoreducens, Selonomonas sp., Methylobacterium sp. and Denitrobacter sp. was found significantly greater in inulin supplemented pigs. Similarly, the abundance of OTUs representing Bacteroides intestinalis, Selonomonas sp., and Phascolarcobacterium faecium was found significantly greater in ginger supplemented pigs. In contrast, the abundance of OTUs representing pathogenic microorganisms Atopostipes suicloacalis and Bartonella quintana str. Toulouse was significantly reduced in ginger and inulin supplemented pigs. The OTUs were found to be clustered under two major phylotypes; ginger-inulin and control-tetracycline. Additionally, the abundance of OTUs was similar in ginger and inulin supplemented pigs. The results suggest the potential of ginger and prebioticsto replace antibiotics in the diet of grower pig.

    Mark I. Avigan

    2016-03-01

    Full Text Available In the United States (US, the risk of hepatotoxicity linked to the widespread use of certain herbal products has gained increased attention among regulatory scientists. Based on current US law, all dietary supplements sold domestically, including botanical supplements, are regulated by the Food and Drug Administration (FDA as a special category of foods. Under this designation, regulatory scientists do not routinely evaluate the efficacy of these products prior to their marketing, despite the content variability and phytochemical complexity that often characterizes them. Nonetheless, there has been notable progress in the development of advanced scientific methods to qualitatively and quantitatively measure ingredients and screen for contaminants and adulterants in botanical products when hepatotoxicity is recognized.

    Full Text Available Background: European Regulation 1924/2006 states that all health claims made on foods need to be substantiated scientifically. Objective: To apply the PASSCLAIM criteria for the scientific substantiation of health claims on foods to herbal supplements containing Ginkgo biloba. Evaluation of three selected claimed health effects for G. biloba (improvement of blood circulation, improvement of symptoms of old age, and improvement of memory was achieved through review of publicly available scientific data. A total of 35 human intervention studies were evaluated. Commercially available products claimed to contain mainly G. biloba (N=29 were randomly sampled in the Netherlands and analyzed for their content on ginkgo extract. Also, a toxicological risk assessment was performed. Results: The three selected health claims investigated could not be substantiated. This was mainly because of a lack of data from studies in healthy volunteers. In most studies results performed with a 24% standardized G. biloba extract were described. However, our chemical analysis showed that 25 of the 29 sampled products did not contain the required minimum 24% standardized extract. Moreover, in most preparations the content of substances typical for G. biloba did not conform to what was declared on the label. Since toxicity data for G. biloba are very limited, a safety limit could not be established. Conclusions : Evidence is lacking for three health claims of herbal products with G. biloba. Neither safety nor efficacy can be guaranteed at the recommended daily dose. The multidisciplinary approach described in this paper provides good insight into issues that are relevant for the evaluation of health claims for herbal food supplements.

    2010-10-01

    Full Text Available Abstract Background Over the past several decades, complementary and alternative medications have increasingly become a part of everyday treatment. With the rising cost of prescription medications and their production of unwanted side effects, patients are exploring herbal and other natural remedies for the management and treatment of psychological conditions. Psychological disorders are one of the most frequent conditions seen by clinicians, and often require a long-term regimen of prescription medications. Approximately 6.8 million Americans suffer from generalized anxiety disorder. Many also suffer from the spectrum of behavioural and physical side effects that often accompany its treatment. It is not surprising that there is universal interest in finding effective natural anxiolytic (anti-anxiety treatments with a lower risk of adverse effects or withdrawal. Methods An electronic and manual search was performed through MEDLINE/PubMed and EBSCO. Articles were not discriminated by date of publication. Available clinical studies published in English that used human participants and examined the anxiolytic potential of dietary and herbal supplements were included. Data were extracted and compiled into tables that included the study design, sample population, intervention, control, length of treatment, outcomes, direction of evidence, and reported adverse events. Results A total of 24 studies that investigated five different CAM monotherapies and eight different combination treatments and involved 2619 participants met the inclusion criteria and were analyzed. There were 21 randomized controlled trials and three open-label, uncontrolled observational studies. Most studies involved patients who had been diagnosed with either an anxiety disorder or depression (n = 1786. However, eight studies used healthy volunteers (n = 877 who had normal levels of anxiety, were undergoing surgery, tested at the upper limit of the normal range of a trait anxiety

    Full Text Available Abstract Background Complementary and alternative medicine (CAM use, including herbals and multivitamin supplements, is quite common in the U.S., and has been shown to be highest in breast cancer survivors. However, limited data are currently available for CAM usage among African Americans. Thus, we sought to determine the prevalence of multivitamins, folic acid and herbal supplement usage in African American breast cancer survivors, and to compare the characteristics of users and nonusers. Methods A cohort study of breast cancer survivors, who completed the 1999 Black Women's Health Study questionnaire and self-reported having been diagnosed with breast cancer between 1995 and 1999, comprised the study population. In this study, the intake of natural herbs, multivitamins and folic acid at least three days per week within the past two years was used as a proxy for typical usage of this complimentary alternative medicine (CAM modality. Results A total of 998 breast cancer survivors were identified. Overall, 68.2% had used either herbals or multivitamin supplements or both. The three most frequently used herbals were garlic (21.2%, gingko (12.0%, and echinacea (9.4%. The multivariate analysis determined that single marital status (OR = 1.58; 95%CI: 1.04-2.41, and alcohol consumption of 1-3 drinks per week (OR = 1.86, 95%CI: 1.28-2.68 were significantly associated with increased herbal use. Multivitamin use was significantly lower among obese women (OR = 0.66, 95%CI: 0.46-0.94 and current smokers (OR = 0.53, 95%CI: 0.34-0.82. Conclusions A significant number of African American breast cancer survivors are using herbals and multivitamins as CAM modality. Additional research is needed to understand the impact of herbals and multivitamins in African American breast cancer survivors.

  13. Herbal supplement extends life span under some environmental conditions and boosts stress resistance.

    Directory of Open Access Journals (Sweden)

    Bryant Villeponteau

    Full Text Available Genetic studies indicate that aging is modulated by a great number of genetic pathways. We have used Drosophila longevity and stress assays to test a multipath intervention strategy. To carry out this strategy, we supplemented the flies with herbal extracts (SC100 that are predicted to modulate the expression of many genes involved in aging and stress resistance, such as mTOR, NOS, NF-KappaB, and VEGF. When flies were housed in large cages with SC100 added, daily mortality rates of both male and female flies were greatly diminished in mid to late life. Surprisingly, SC100 also stabilized midlife mortality rate increases so as to extend the maximum life span substantially beyond the limits previously reported for D. melanogaster. Under these conditions, SC100 also promoted robust resistance to partial starvation stress and to heat stress. Fertility was the same initially in both treated and control flies, but it became significantly higher in treated flies at older ages as the fertility of control flies declined. Mean and maximum life spans of flies in vials at the same test site were also extended by SC100, but the life spans were short in absolute terms. In contrast, at an independent test site where stress was minimized, the flies exhibited much longer mean life spans, but the survival curves became highly rectangular and the effects of SC100 on both mean and maximum life spans declined greatly or were abolished. The data indicate that SC100 is a novel herbal mix with striking effects on enhancing Drosophila stress resistance and life span in some environments, while minimizing mid to late life mortality rates. They also show that the environment and other factors can have transformative effects on both the length and distribution of survivorship, and on the ability of SC100 to extend the life span.

    After the incidences of induction of aristolochic acid nephropathy after consumption of herbal weight loss preparations that accidentally contained aristolochic acids (AAs), several countries defined national restrictions on the presence of AAs in food, including plant food supplements (PFS) and herbal products. This study investigates whether the risks associated with exposure to AAs via PFS and herbal products are at present indeed negligible. Data reported in literature on AA levels in PFS and other herbal products and also obtained from a new series of PFS in the present study were used to calculate the estimated daily intakes (EDIs) and corresponding margins of exposure (MOEs). Available literature data revealed that 206 out of 573 samples were found to contain aristolochic acid I (AAI) and/or aristolochic acid II (AAII). The results obtained from recently collected PFS revealed that both AAI and AAII were detected in three out of 18 analysed PFS at levels up to 594.8 and 235.3 µg g(-1), respectively, being in line with the levels reported in literature. The EDIs resulting from intake of these PFS resulted in MOEs that were generally below 10,000, corroborating the priority for risk management. Although these results refer to PFS collected by targeted sampling strategies, the data reveal that AA-containing PFS are still freely available. When considering that the use of these samples may be limited to shorter periods of time, the EDIs might be lower, but MOE values would still be lower than 10,000 for more than 50% of the AA-containing PFS and herbal products. In conclusion, the presence of AAs in PFS and herbal products even several years after instalment of the legal restrictions still raises concern, especially for people who frequently use the respective PFS and herbal products.

    Full Text Available We used the carbon tetrachloride (CCl4 induced liver cirrhosis model to test the molecular mechanism of action involved in cirrhosis-associated cardiac hypertrophy and the effectiveness of Ocimum gratissimum extract (OGE and silymarin against cardiac hypertrophy. We treated male wistar rats with CCl4 and either OGE (0.02 g/kg B.W. or 0.04 g/kg B.W. or silymarin (0.2 g/kg B.W.. Cardiac eccentric hypertrophy was induced by CCl4 along with cirrhosis and increased expression of cardiac hypertrophy related genes NFAT, TAGA4, and NBP, and the interleukin-6 (IL-6 signaling pathway related genes MEK5, ERK5, JAK, and STAT3. OGE or silymarin co-treatment attenuated CCl4-induced cardiac abnormalities, and lowered expression of genes which were elevated by this hepatotoxin. Our results suggest that the IL-6 signaling pathway may be related to CCl4-induced cardiac hypertrophy. OGE and silymarin were able to lower liver fibrosis, which reduces the chance of cardiac hypertrophy perhaps by lowering the expressions of IL-6 signaling pathway related genes. We conclude that treatment of cirrhosis using herbal supplements is a viable option for protecting cardiac tissues against cirrhosis-related cardiac hypertrophy.

    Background The Drug-Induced Liver Injury Network (DILIN) studies hepatotoxicity due to conventional medications as well as herbals and dietary supplements (HDS). Rationale To characterize hepatotoxicity and its outcomes from HDS versus medications, patients with hepatotoxicity attributed to medications or HDS were enrolled prospectively between 2004 and 2013. The study took place among eight US referral centers that are part of the DILIN. Consecutive patients with liver injury referred to a DILIN center were eligible. The final sample comprised 130 (15.5%) of all subjects enrolled (839) who were judged to have experienced liver injury due to HDS. Hepatotoxicity due to HDS was evaluated by expert opinion. Demographic and clinical characteristics and outcome assessments including death and liver transplantation were ascertained. Cases were stratified and compared according to the type of agent implicated in liver injury; 45 had injury due to bodybuilding HDS, 85 due to non-bodybuilding HDS, and 709 due to medications. Main Results Liver injury due to HDS increased from 7% to 20% (p Bodybuilding HDS caused prolonged jaundice (median 91 days) in young men but did not result in any fatalities or liver transplantation. The remaining HDS cases presented as hepatocellular injury, predominantly in middle-aged women and more frequently led to death or transplantation compared to injury from medications (13% vs. 3%, p bodybuilding HDS is more severe than from bodybuilding HDS or medications, as evidenced by differences in unfavorable outcomes; death and transplantation.

    Diabetes mellitus (DM) has been one of the most common chronic diseases that create great impacts on both morbidities and mortalities. Many patients who suffering from this disease seek for complementary and alternative medicine. The aim of this study was to determine the prevalence and related factors of herbal and dietary supplement (HDS) use in patients with DM type 2 at a single university hospital in Thailand. A cross-sectional study was performed in 200 type 2 DM patients via face-to-face structured interviews using developed questionnaires comprised of demographic data, diabetes-specific information, details on HDS use, and medical adherence. From the endocrinology clinic, 61% of total patients reported HDS exposure and 28% were currently consuming. More than two-thirds of HDS users did not notify their physicians, mainly because of a lack of doctor concern; 73% of cases had no awareness of potential drug-herb interaction. The use of drumstick tree, turmeric and bitter gourd and holy mushroom were most frequently reported. The main reasons for HDS use were friend and relative suggestions and social media. Comparisons of demographic characteristics, medical adherence, and hemoglobin A1c among these non-HDS users, as well as current and former users, were not statistically significantly different. This study revealed a great number of DM patients interested in HDS use. The use of HDS for glycemic control is an emerging public health concern given the potential adverse effects, drug interactions and benefits associated with its use. Health care professionals should aware of HDS use and hence incorporate this aspect into the clinical practice.

    Herbal supplements hawthorn and ashwagandha (Indian ginseng) are indicated for cardiac illnesses and may be taken by patients receiving digoxin therapy. Because both hawthorn and ashwagandha are known to interfere with serum digoxin measurements using certain digoxin immunoassays, we investigated potential interference of these two herbal supplements with the new homogenous sequential chemiluminescent assay for digoxin based on the luminescent oxygen channeling technology (LOCI digoxin) for application on the Dimension and Vista platform. When aliquots of a drug-free serum pool were supplemented with various amounts of hawthorn (three different commercial preparations) or ashwagandha (two different commercial preparations) and apparent digoxin values were measured using LOCI digoxin assay on Dimension Vista 1500 analyzer we observed none-detected values except when aliquots were supplemented with very high amounts of the herbal extracts. When aliquots of a serum digoxin pool (prepared by pooling specimens from patients receiving digoxin) where further supplemented with various amounts of these supplements and digoxin concentrations were remeasured, statistically significant falsely higher digoxin values were observed only in specimens containing very high amounts of these supplements. Such interference may not be clinically significant. We conclude that new LOCI digoxin assay is virtually free from interferences of herbal supplements, hawthorn, and ashwagandha.

    Dietary supplements represent an increasingly common source of drug-induced liver injury. Hydroxycut is a popular weight loss supplement which has previously been linked to hepatotoxiciLy, although the individual chemical components underlying liver injury remain poorly understood. We report two cases of acute hepatitis in the seLLing of Hydroxycut exposure and describe possible mechanisms of liver injury. We also comprehensively review and summarize the existing literature on commonly used weight loss supplements,and their individual components which have demonstrated potential for liver toxicity. An increased effort to screen for and educate patients and physicians about supplement-associated hepatotoxicity is warranted.

    The consumption of plant food supplements is increasing steadily and more and more, these products are bought through internet. Often the products sold through internet are not registered or declared with a national authority, meaning that no or minimal quality control is performed and that they could contain herbs or plants that are regulated. Stationary Phase Optimized Selectivity Liquid Chromatography (SOS-LC) was evaluated for the development of specific fingerprints, to be used for the detection of targeted plants in plant food supplements. Three commonly used plants in plant food supplements and two regulated plants were used to develop fingerprints with SOS-LC. It was shown that for all plants specific fingerprints could be obtained, allowing the detection of these targeted plants in triturations with different herbal matrices as well as in real samples of suspicious supplements seized by the authorities. For three of the five plants a more specific fingerprint was obtained, compared to the ones developed on traditional columns described in literature. It could therefore be concluded that the combination of segments of different types of stationary phases, as used in SOS-LC, has the potential of becoming a valuable tool in the quality control and the identification of crude herbal or plant material and in the detection of regulated plants in plant food supplements or other herbal preparations.

    Objectives: The study aimed to evaluate the effectiveness of the combination of two natural extracts in varying ratios for removal of smear layer either alone or supplemented with sonic agitation. Materials and Methods: Fifty extracted single-rooted teeth were collected, disinfected and decoronated below the cementoenamel junction to obtain standardized root length of 10 mm. Root canals were instrumented using rotary files at working length 1 mm short of the apex. Specimens were divided into six groups according to the irrigation protocol as follows: Group A – Distilled water, Group B – 17% ethylenediaminetetraacetic acid, Group C – Herbal extracts in 1:1 ratio, Group D – Herbal extracts in 1:1 ratio supplemented with sonic agitation, Group E – Herbal extracts in 2:1 ratio, Group F – Herbal extracts in 2:1 ratio supplemented with sonic agitation. Specimens were longitudinally sectioned and evaluated under scanning electron microscope for smear layer removal efficacy. Obtained scores were statistically analyzed using one-way analysis of variance and post-hoc test. Results: Among all, Group B showed the best results followed by Group F. Remaining other groups showed inferior outcome (P extracts in 2:1 ratio was slightly better than 1:1 ratio and the smear layer removal efficacy was further improved when accompanied with sonic agitation.

    To describe the use of dietary vitamin, mineral and herbal supplements before and during pregnancy. Pregnant women attending for antenatal care at two tertiary Sydney hospitals between January and March 2014 completed an anonymous survey. Information on general maternal and pregnancy characteristics and the use of dietary and herbal supplements, including type, duration and sources of information, was collected. Frequency and contingency tabulations were performed. A total of 612 women agreed to participate (91% response rate). Of 589 women included in the analysis, mean gestational age at the time of survey was 28.5 weeks (SD 8.3), 55% had no children, and 67% were tertiary-educated. Overall, 62.9% of women reported taking a multivitamin (MV) and/or folic acid (FA) supplement in the 3 months prepregnancy, and 97.5% took a MV and/or FA in the first trimester. At the time of the survey, 93.8% of women were taking at least one supplement (median 2, range 1-13). During pregnancy, 79.1% of women were taking MVs, including 59.2% taking MV only and 19.9% taking MV and FA. The five most common supplements outside of a MV were FA (31%), iron (30%), vitamin D (23%), calcium (13%) and fish oil (12%). Reported herbal supplement rates were low. Folic acid, MVs and other supplements use during and prepregnancy is relatively high, although prepregnancy FA supplementation rates could still be improved. Further research on the actual dosages and dietary intakes consumed is needed to examine whether pregnant women have adequate intake of nutrients, regardless of supplement use. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    The experiment tested the effect of Digestarom® herbal supplementation on the antioxidant content, lipid oxidation and fatty acid profile of rabbit meat. At kindling, rabbit does and litters were divided into two dietary groups (N=162 kits/dietary group) and fed either a control diet (C) or the C diet supplemented with Digestarom® (D: 300mg/kg). At weaning (35days) four experimental fattening groups (54 rabbits each) were considered: CC, CD, DC and DD. After slaughtering (12weeks of age), Longissimus thoracis et lumborum muscles were dissected from 20 rabbits/group and analyzed. Rabbit meat of DD group was enriched in essential C18:3 n-3 fatty acid and in other long-chain PUFA of n-3 series. Despite meat of DD group displayed the highest peroxidability index, TBARs value was the lowest. Meat antioxidant content followed the rank order: DD>CD>DC>CC. Digestarom® improved fatty acid composition and oxidative status of rabbit meat, particularly when administered from weaning throughout the growing period.

    2012-04-01

    Hyperglycemia is a pathological condition associated with prediabetes and diabetes. The incidence of prediabetes and diabetes is increasing and imposes great burden on healthcare worldwide. Patients with prediabetes and diabetes have significantly increased risk for cardiovascular diseases and other complications. Currently, management of hyperglycemia includes pharmacological interventions, physical exercise, and change of life style and diet. Food supplements have increasingly become attractive alternatives to prevent or treat hyperglycemia, especially for subjects with mild hyperglycemia. This review summarized current patents and patent applications with relevant literature on five commonly used food supplements with claims of hypoglycemic effects, including emblica officinalis (gooseberry), fenugreek, green tea, momordica charantia (bitter melon) and cinnamon. The data from human clinical studies did not support a recommendation for all five supplements to manage hyperglycemia. Fenugreek and composite supplements containing emblica officinalis showed the most consistency in lowering fasting blood sugar (FBS) or glycated hemoglobin (HbA1c) levels in diabetic patients. The hypoglycemic effects of cinnamon and momordica charantia were demonstrated in most of the trials with some exceptions. However, green tea exhibited limited benefits in reducing FBS or HbA1c levels and should not be recommended for managing hyperglycemia. Certain limitations are noticed in a considerable number of clinical studies including small sample size, poor experimental design and considerable variations in participant population, preparation format, daily dose, and treatment duration. Future studies with more defined participants, standardized preparation and dose, and improved trial design and size are warranted.

    An analytical procedure for selective extraction of sildenafil and vardenafil in herbal dietary supplements (HDSs) has been set up by using the magnetic molecularly imprinted polymers (MMIPs) as the extraction and clean-up materials, followed by high performance liquid chromatography-ultraviolet (HPLC-UV). The MMIPs were prepared by a surface molecular imprinting technique, using Fe{sub 3}O{sub 4} magnetite as a magnetically susceptible component, sildenafil as template molecule, 2-(trifluoromethyl) acrylic acid (TFMAA) as functional monomer, ethylene glycol dimethacrylate (EGDMA) as polymeric matrix components. The MMIPs were characterized by transmission electron microscope (TEM), Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM), respectively. The heterogeneity of the MMIPs was modeled with the Freundlich isotherm equation. The resulting MMIPs had high recognition ability and fast binding kinetics for sildenafil. The MMIPs were used as dispersive solid-phase extraction (DSPE) materials to selectively extract sildenafil and vardenafil from HDSs, the contents of sildenafil and vardenafil were found to be 8.05 and 3.86 {mu}g g{sup -1}, respectively, and the average recoveries in spiked HDSs were 70.91-91.75% with a relative standard deviation (R.S.D.) below 7%.

    The effect of a new herbal composition, HemoHIM, on immune functions was examined in aged mice, in which various immune responses had been impaired. The composition HemoHIM was prepared by adding the ethanol-insoluble fraction to the total water extract of a mixture of three edible herbs, Angelica Radix, Cnidium Rhizoma and Paeonia Radix. Supplementation to the aged mice with HemoHIM restored the proliferative response and cytokine production of splenocytes with a response to ConA. Also, HemoHIM recovered the NK cell activity which had been impaired in the aged mice. Meanwhile aging is known to reduce the Th1-like function, but not the Th2-like function, resulting in a Th1/Th2 imbalance. HemoHIM restored the Th1/Th2 balance in the aged mice through enhanced IFN-gamma and IgG2a production, and conversely a reduced IL-4 and IgG1 production. It was found that one factor for the Th1/Th2 imbalance in the aged mice was a lower production of IL-12p70. However, HemoHIM restored the IL-12p70 production in the aged mice. These results suggested that HemoHIM was effective for the restoration of impaired immune functions of the aged mice and therefore could be a good recommendation for immune restoration in elderly humans.

    StemSport (SS; StemTech International, Inc. San Clemente, CA) contains a proprietary blend of the botanical Aphanizomenon flos-aquae and several herbal antioxidant and anti-inflammatory substances. SS has been purported to accelerate tissue repair and restore muscle function following resistance exercise. Here, we examine the effects of SS supplementation on strength adaptations resulting from a 12-week resistance training program in healthy young adults. Twenty-four young adults (16 males, 8 females, mean age = 20.5 ± 1.9 years, mass = 70.9 ± 11.9 kg, stature = 176.6 ± 9.9 cm) completed the twelve week training program. The study design was a double-blind, placebo controlled parallel group trial. Subjects either received placebo or StemSport supplement (SS; mg/day) during the training. 1-RM bench press, 1-RM leg press, vertical jump height, balance (star excursion and center of mass excursion), isokinetic strength (elbow and knee flexion/extension) and perception of recovery were measured at baseline and following the 12-week training intervention. Resistance training increased 1-RM strength (p 0.10). These data suggest that compared to placebo, the SS herbal/botanical supplement did not enhance training induced adaptations to strength, balance, and muscle function above strength training alone.

    We developed a convenient method by coupling frontal elution paper chromatography with desorption corona beam ionization mass spectrometry (DCBI-MS) for rapid determination of chlorphenamine added in herbal medicines or dietary supplements. In this method, the ethanol extract of the herbal products was spotted directly onto an isosceles triangular filter paper sheet, and then the paper sheet was developed under strong elution condition with the sample zone migrating at the solvent front. The analyte was finally condensed at the V-shaped tip which could then be placed under the visible plasma beam of DCBI for ionization. The overall procedure took less than 5 min. The frontal elution paper chromatography on a triangular plate used in this work improved the signal intensity of chlorphenamine by 30-fold due to the analyte condensing at the tip and the reduction of the background suppression. Furthermore, the paper sheet also functioned as a filter in the analysis of solid or powder samples, which can increase the analytical throughput by omitting the step of centrifugation. The proposed method in current study was successfully applied in the determination of chlorphenamine in herbal medicines. Chlorphenamine was detected in four of the twelve types of herbal medicines examined in this study. The limit of detection was 200 ng/mL (2.0 ng absolute) in full-scan positive-ion mode and the linear range was from 5.0 μg/mL to 50 μg/mL with satisfactory linear coefficient (R(2) (the square of the correlation coefficient)=0.895). Good reproducibility was achieved with relative standard deviations (RSDs) less than 15.0% and the recoveries of chlorphenamine ranged from 84.3 to 90.6%.

    PURPOSE: More and more patients use herbal medical products (HMP) and dietary supplements (DS). Due to the possibility of drug interactions and side effects, it is important that physicians are aware of the use. The aim of the present cross sectional survey was to analyse the consumption of HMP......% of the 211 HMP and DS used daily prior to admission were recorded in the hospital files. CONCLUSIONS: The use of HMP and DS was frequent among surgical and medical patients. The use was often not recorded in the hospital files and patients' knowledge of possible side effects and drug-interactions was minimal....... the products on demand. The most frequently used product was multivitamins (82 patients = 41%). Totally, 61% of the products were used on the patients' own initiative. In 3% of the used products, patients were aware of possible side effects. No patients were aware of possible drug interactions. Only 21...

    Nine herbal dietary supplements intended to be beverages for enhancing sexual performance were analyzed before their possible launch on the market. Four of them contained a sildenafil analog reported for the first time as an adulterant. After isolation and characterization using NMR, MS, IR and UV, this analog was named propoxyphenyl-thiohydroxyhomosildenafil as the ethoxy chain on the phenyl ring of the already known analog thiohydroxyhomosildenafil was replaced by a propoxy moiety. One formulation was tainted with thiosildenafil, another unapproved PDE-5 inhibitor. Sildenafil along with the natural alkaloid tetrahydropalmatine that has no documented effect for enhancing erectile dysfunction were identified in two formulations. Another formulation was adulterated with phentolamine, a drug that is not approved for boosting male sexual performance when taken orally. The last formulation containing osthole, a bioactive natural coumarine improving sexual dysfunction, is most probably truly natural.

  5. The role of kelp crabs as consumers in bull kelp forests—evidence from laboratory feeding trials and field enclosures

    Full Text Available The Northern kelp crab (Pugettia producta and the graceful kelp crab (Pugettia gracilis are common primary consumers in bull kelp beds near the San Juan Islands (Salish Sea, NE Pacific. In this system, urchins (often considered the most voracious herbivores exerting top-down control on kelp beds tend to remain sedentary because of the high availability of detrital macroalgae, but the extent to which kelp crabs consume kelp (and other food options is largely unknown. I conducted four types of laboratory feeding experiments to evaluate kelp crab feeding patterns: (1 feeding electivity between bull kelp (Nereocystis luetkeana and seven species of co-occurring local macroalgae; (2 feeding electivity on aged vs. fresh bull kelp; (3 feeding preference between N. luetkeana and small snails (Lacuna sp.; and (4 scaling of feeding rate with body size in P. producta and P. gracilis. In choice experiments, P. producta consumed greater mass of N. luetkeana than of other macroalgal species offered and elected to eat fresh bull kelp over aged. However, P. producta also consumed snails (Lacuna sp., indicating more generalized feeding than previously suspected. Feeding rates for P. producta exceeded the expected 3∕4 scaling rule of metabolic rates, indicating that larger P. producta may have a disproportionately large impact on bull kelp. A subtidal field experiment, designed to assess the influence of consumers on juvenile bull kelp net tissue gain, found that only fully enclosed (protected bull kelp increased in wet mass and blade length. Herbivory by kelp crabs, among other consumers, is likely to play a previously unrecognized role in mediating the growth and survival of this annual kelp species within the Salish Sea.

  6. A Mathematical Model for Estimation of Kelp Bed Productivity: Age Dependence and Contributions of Subsurface Kelp

    Macrocystis pyrifera, giant kelp, is a major primary producer of the California coastal ocean that provides habitat for marine species through the formation of massive kelp beds. The estimation of primary productivity of these kelp beds is essential for a complete understanding of their health and of the biogeochemistry of the region. Current methods involve either the application of a proportionality constant to remotely sensed biomass or in situ frond density measurements. The purpose of this research was to improve upon conventional primary productivity estimates by developing a model which takes into account the spectral differences among juvenile, mature, and senescent tissues as well as the photosynthetic contributions of subsurface kelp. A modified version of a seagrass productivity model (Zimmerman 2006) was used to quantify carbon fixation. Inputs included estimates of the underwater light field as computed by solving the radiative transfer equation (with the Hydrolight(TM) software package) and biological parameters obtained from the literature. It was found that mature kelp is the most efficient primary producer, especially in light-limited environments, due to increased light absorptance. It was also found that incoming light attenuates below useful levels for photosynthesis more rapidly than has been previously accounted for in productivity estimates, with productivity dropping below half maximum at approximately 0.75 m. As a case study for comparison with the biomass method, the model was applied to Isla Vista kelp bed in Santa Barbara, using area estimates from the MODIS-ASTER Simulator (MASTER). A graphical user-interface was developed for users to provide inputs to run the kelp productivity model under varying conditions. Accurately quantifying kelp productivity is essential for understanding its interaction with offshore ecosystems as well as its contribution to the coastal carbon cycle.

    Full Text Available The experiment aimed to study the effect of Digestarom® dietary inclusion (herbal formulation containing a mixture of essential oils, herbs, spices and extracts on apparent digestibility and digestive ecosystem of growing rabbits, as well as the effects of its supplementation before and after weaning on growth performance. At kindling, rabbit does and litters were divided into 2 dietary groups (51 does/group and fed either a control diet (C or a diet supplemented with 300 mg Digestarom®/kg diet (D until weaning, which occurred at 35 d (before weaning supplementation. Each group was further divided into 3 dietary groups: CC received the control diet and DD received the D diet from 5 to 12 wk of age, and DC were fed with D (from 5 to 8 wk of age and C diets (from 8 to 12 wk of age (after weaning supplementation; 54 kits/group. An in vivo digestibility trial and a faecal microbial count were carried out on growing rabbits that received only the C or D diets during the trial. The C group showed higher DM intake than D group (215 vs. 196 g/d; P<0.05. The faecal digestibility of ether extract (75.9 vs. 59.8%; P<0.001, cellulose (25.9 vs. 20.6%; P<0.05 and gross energy (51.8 vs. 49.1%; P<0.05 was higher for C than for D group, whereas that of starch (98.9 vs. 98.8%; P<0.001 and the digestible protein to digestible energy ratio (13.9 vs. 13.2 g digestible protein/MJ digestible energy; P<0.01 was the highest for rabbits fed D diet. Stomach and caecal pH, caecal and faecal microbial counts were independent of the dietary treatment. The only exception was the stomach pH in 8 wk-old rabbits, which had the lowest value in C rabbits (P<0.05. The D supplementation before weaning improved feed conversion ratio throughout the growing phase (4.3 vs. 4.4 for D and C, respectively; P<0.05, whereas significant differences in daily weight gain, feed conversion ratio and mortality were observed only in the first period after weaning.

    Objective. The aim of the study was to explore the association between women's use of herbal dietary supplement Si-Wu-Tang during the postpartum period and their health-related quality of life. Methods. This is a population-based correlational study. We used multistage, stratified, systematic sampling to recruit 24,200 pairs of postpartum women and newborns from the Taiwan National Birth Registry in 2005. A structured questionnaire was successfully administered to 87.8% of the sampled population. Trained interviewers performed home interviews 6 months after the women's deliveries between June 2005 and July 2006. The Medical Outcomes Study 36-item Short-Form (SF-36) was used to measure the quality of life of the women along with the frequency of Si-Wu-Tang use. Results. Si-Wu-Tang use after delivery improved women's score for bodily pain and also improved their score for mental health when used more than 10 times. In addition, there were increases in general health and vitality scores in the group who continuously used Si-Wu-Tang more than 10 times after using Sheng-Hua-Tang. Conclusion. Use of Si-Wu-Tang after delivery may be associated with women's health-related quality of life especially for those who previously used Sheng-Hua-Tang. These results are exploratory and need to be replicated.

    The distributions and abundances of species and populations change almost continuously. Understanding the processes responsible is perhaps ecology’s most fundamental challenge. Kelp-forest ecosystems in southwest Alaska have undergone several phase shifts between alga- and herbivore-dominated states in recent decades. Overhunting and recovery of sea otters caused the earlier shifts. Studies focusing on these changes demonstrate the importance of top-down forcing processes, a variety of indirect food-web interactions associated with the otter-urchin-kelp trophic cascade, and the role of food-chain length in the coevolution of defense and resistance in plants and their herbivores. This system unexpectedly shifted back to an herbivore-dominated state during the 1990s, because of a sea-otter population collapse that apparently was driven by increased predation by killer whales. Reasons for this change remain uncertain but seem to be linked to the whole-sale collapse of marine mammals in the North Pacific Ocean and southern Bering Sea. We hypothesize that killer whales sequentially "fished down" pinniped and sea-otter populations after their earlier prey, the great whales, were decimated by commercial whaling. The dynamics of kelp forests in southwest Alaska thus appears to have been influenced by an ecological chain reaction that encompassed numerous species and large scales of space and time.

    One hundred and sixty food supplements (FS) marketed for weight loss and mainly purchased on the Internet were analyzed. All the FS were claimed as 100% natural containing only natural compounds, plant extracts and/or vitamins and the presence of an active pharmaceutical ingredient (API) was never mentioned. (1)H NMR spectroscopy was used for detecting the presence of adulterants and for their identification and quantification. Mass spectrometry was used as a complementary method for supporting their identification. Among the 164 samples considered because capsules from 5 different blisters of the same FS were analyzed, 56% were tainted with six API. Forty three contained sibutramine as single adulterant (26%), 9 phenolphthalein (6%) and 23 a mixture of these API (14%) that were both withdrawn from the market several years ago because of toxicity concerns. Sildenafil was found in 12 samples, either as a single adulterant (n=5) or in combination with sibutramine (n=3), phenolphthalein (n=3) and both sibutramine and phenolphthalein (n=1). Fluoxetine was present in 4 formulations, alone (n=3) or in combination with sibutramine and orlistat (n=1). At last, lorcaserine was detected in one FS. The content of sibutramine per dosage unit was comprised between 0.1 and 22 mg and that of phenolphthalein between 0.05 and 56 mg. The study also highlights poor manufacturing practices as evidenced for instance by the variability of API in capsules from different blisters of the same box. This paper demonstrates the need for more effective quality control of weight loss FS and the efficiency of (1)H NMR spectroscopy for the detection of tainted FS.

    The population-based incidence rate of drug-induced liver injury (DILI) in the USA is not known. The Drug-Induced Liver Injury Network (DILIN) accrues cases of hepatotoxicity due to medications and herbal and dietary supplements (HDS) from limited geographical areas. The current analysis was an ancillary study of DILIN aimed at determining the annual incidence of DILI in the USA on a population basis, through surveillance in the state of Delaware. At the outset of the study, there were 41 gastroenterologists in the state of Delaware and all agreed to participate in surveillance for DILI, which comprised active reporting of suspected cases to the DILIN. The gastroenterologists underwent training in the diagnosis of DILI and were provided with DILIN inclusion criteria. Only cases that met the DILIN laboratory inclusion criteria in 2014 were included in the incidence calculation, and these patients were invited to participate in the DILIN Prospective Study. The number of suspected cases that met inclusion criteria served as the numerator and the 2014 Delaware adult population as the denominator. During 2014, 23 patients were identified by the surveillance network, 20 of whom met DILIN laboratory inclusion criteria, leading to an incidence of 2.7 cases of DILI per 100,000 adult residents [95% confidence interval (CI) 1.5-3.9 per 100,000]. Fourteen subjects agreed to participate in the DILIN; six declined. Among enrolled cases, the mean age was 51 years, 57% were women, and 71% were white. Eight cases were attributed to antibiotics (36%) and other drugs (21%) and six to HDS (43%). The pattern of injury was hepatocellular in all HDS cases, but only 50% of conventional drug cases (p = 0.05), which more commonly presented with eosinophilia (p = 0.47) and higher alkaline phosphatase levels (p = 0.05). Half of patients were jaundiced, none developed liver failure, and all recovered without the need for transplantation. Prospective, gastroenterologist

    2014-12-01

    Routine DNA barcoding of the Haida Gwaii seaweed flora revealed "endemic species" attributed initially to this region's past as a glacial refugium. However, subsequent barcode records from central California rapidly eroded this list leaving species characterized by disjunct distributions (DD) between California and Haida Gwaii. This observation prompted a more detailed look at species for California and British Columbia and revealed that 33 of 180 DNA-barcoded genetic groups in common between these regions (~18%) predominantly displayed DD between California and northern British Columbia. A previous discovery that a red abalone shell found in Haida Gwaii (far north of its range) had a float-bearing kelp (Nereocystis luetkeana) holdfast attached to it prompted a closer consideration of the COI-5P barcode data in support of a "kelp conveyor hypothesis." The hypothesis posits that there has been a net migration of Californian species to northern British Columbia the vector being species growing on substrata carried along with kelp rafts on the winter Davidson Current.

    Dietary supplements are commonly used by patients as part of their medical care plan. Often clinicians may not be aware of their use, because patients do not always consider these to be medications. All clinicians need to continually ask patients about their use of dietary supplements when collecting a medication history. Dietary supplements and prescription medications often share similar enzymatic pathways for their metabolism. These interactions may lead to severe adverse reactions. This article reviews available evidence for a variety of dietary supplements in select disease categories.

    Kelp forests provide habitat for diverse and abundant fish assemblages, but the extent to which kelp provides a source of energy to fish and other predators is unclear. To examine the use of kelp-derived energy by fishes we estimated the contribution of kelp- and phytoplankton-derived carbon using carbon (δ13C) and nitrogen (δ15N) isotopes measured in muscle tissue. Benthic-foraging kelp greenling (Hexagrammos decagrammus) and pelagic-foraging black rockfish (Sebastes melanops) were collected at eight sites spanning ∼35 to 60°N from the California Current (upwelling) to Alaska Coastal Current (downwelling) in the northeast Pacific Ocean. Muscle δ13C values were expected to be higher for fish tissue primarily derived from kelp, a benthic macroalgae, and lower for tissue primarily derived from phytoplankton, pelagic microalgae. Muscle δ13C values were higher in benthic-feeding kelp greenling than in pelagic-feeding black rockfish at seven of eight sites, indicating more kelp-derived carbon in greenling as expected. Estimates of kelp carbon contributions ranged from 36 to 89% in kelp greenling and 32 to 65% in black rockfish using carbon isotope mixing models. Isotopic evidence suggests that these two nearshore fishes routinely derive energy from kelp and phytoplankton, across coastal upwelling and downwelling systems. Thus, the foraging mode of nearshore predators has a small influence on their ultimate energy source as energy produced by benthic macroalgae and pelagic microalgae were incorporated in fish tissue regardless of feeding mode and suggest strong and widespread benthic-pelagic coupling. Widespread kelp contributions to benthic- and pelagic-feeding fishes suggests that kelp energy provides a benefit to nearshore fishes and highlights the potential for kelp and fish production to be linked.

  12. Herbal products: Marketing strategies and legislation

    Full Text Available Marketing of herbal products in the European Union (EU has been regulated under national legislation for years, leading to differences in legal status of these herbal products. In one member state, a product may be regulated as a food supplement, while in the other member state the same product is considered a medicinal product, thereby subjected to medicinal law. To provide free movement of these products in the inner market, new legislation has been set to improve harmonization. This raises the question what the appropriate positioning and marketing strategy for a herbal product will be under this new EU legislation. This review describes the legal status and registration procedures of different categories of herbal products, taking into account technical requirements and interesting market perspectives . Information was collected from legislation, guidance and official documents published by the European Commission, European Food Safety Authority and the European Medicines Agency. In addition, information was found in conference presentations and the scientific literature from Medline and Scopus. The EU market of herbal products will change considerably in the near future. Many products now marketed as food supplements will be expected to be registered as traditional herbal medicinal product in the future. However, it will take years for the EU to fully implement the new rules for harmonization.

    Terrestrial plants and mammals, although separated by a great evolutionary distance, have each arrived at a highly conserved body plan in which universal allometric scaling relationships govern the anatomy of vascular networks and key functional metabolic traits. The universality of allometric scaling suggests that these phyla have each evolved an 'optimal' transport strategy that has been overwhelmingly adopted by extant species. To truly evaluate the dominance and universality of vascular optimization, however, it is critical to examine other, lesser-known, vascularized phyla. The brown algae (Phaeophyceae) are one such group--as distantly related to plants as mammals, they have convergently evolved a plant-like body plan and a specialized phloem-like transport network. To evaluate possible scaling and optimization in the kelp vascular system, we developed a model of optimized transport anatomy and tested it with measurements of the giant kelp, Macrocystis pyrifera, which is among the largest and most successful of macroalgae. We also evaluated three classical allometric relationships pertaining to plant vascular tissues with a diverse sampling of kelp species. Macrocystis pyrifera displays strong scaling relationships between all tested vascular parameters and agrees with our model; other species within the Laminariales display weak or inconsistent vascular allometries. The lack of universal scaling in the kelps and the presence of optimized transport anatomy in M. pyrifera raises important questions about the evolution of optimization and the possible competitive advantage conferred by optimized vascular systems to multicellular phyla. © 2015 The Author(s).

    In the past two decades, there has been an exponential increase in the use of medicinal herbal products around the world. In various countries, these products are classified and promoted as foods, not pharmaceuticals, which facilitate their availability on the international market without requiring a medical prescription. Since older adults (OAs) are an important and growing sector of the population in many countries, it is important to know the prevalence of their herbal product use, since many OA take herbs along with diverse quantities of prescription and over the counter medications. For this reason, it is important to be aware of the possibilities of health complications due to the concomitant use of diverse medications and herbs. OA are an especially vulnerable population, since many of the human body's physiological activities, such as renal and hepatic detoxification and clearance usually decrease with age. Additionally, information on certain herbal products is either misleading, or simply unavailable. These products may indeed be a therapeutic option, but some can be used properly only under the guidance of a health professional. Those OA taking combinations of various medications and herbal supplements are also more at risk to experience some sort of herb-drug interactions. This publication reviews selected articles related to the use of herbal products by OAs and mentions the various patterns of use and health implications of the concomitant use of herbal products and prescription medications. This topic is currently not fully understood and further research is warranted.

    Kelp forests along temperate and polar coastlines represent some of most diverse and productive habitats on the Earth. Here, we synthesize information from >60 years of research on the structure and functioning of kelp forest habitats in European waters, with particular emphasis on the coasts of UK and Ireland, which represents an important biogeographic transition zone that is subjected to multiple threats and stressors. We collated existing data on kelp distribution and abundance and reanalyzed these data to describe the structure of kelp forests along a spatial gradient spanning more than 10° of latitude. We then examined ecological goods and services provided by kelp forests, including elevated secondary production, nutrient cycling, energy capture and flow, coastal defense, direct applications, and biodiversity repositories, before discussing current and future threats posed to kelp forests and identifying key knowledge gaps. Recent evidence unequivocally demonstrates that the structure of kelp forests in the NE Atlantic is changing in response to climate- and non-climate-related stressors, which will have major implications for the structure and functioning of coastal ecosystems. However, kelp-dominated habitats along much of the NE Atlantic coastline have been chronically understudied over recent decades in comparison with other regions such as Australasia and North America. The paucity of field-based research currently impedes our ability to conserve and manage these important ecosystems. Targeted observational and experimental research conducted over large spatial and temporal scales is urgently needed to address these knowledge gaps.

    Ecological prevention and control of plant disease is very important in sustainable agriculture. Adjusting soil pH value and fertilizing organic microbial fertilizer are two effective measures in this process. Kelp residue contains a large amount of organic compounds and alkaline metal ions. The bio⁃control Bacillus amyloliquefaciens strain Hitwh⁃BA2 was inoculated into kelp residue medium to produce kelp residue microbial fertilizer. Acidic soil and alkaline soil were used to study the effect of kelp residue microbial fertilizer on soil pH and soil suppressive activity. Tip⁃culture method was used to determine soil leachate suppressive activity, which characterized the soil suppressive activity. Results showed that fertilizing kelp residue microbial fertilizer had increased the soil pH and soil suppressive ability significantly, which was verified by peanut validation experiments as well. Peanut potting experiments proved that fertilizing kelp residue microbial fertilizer not only improved the yield of peanuts obviously, but also reduced the amount of Aspergillus parasiticus 95 in peanut geocarposphere soil significantly. Results also showed that fertilizing kelp residue microbial fertilizer was effective in reducing A. parasiticus 95 infection rate. So the kelp residue microbial fertilizer has good potential application prospect on ecological prevention and control of plant disease.

    Kelp forests (Order Laminariales) form key biogenic habitats in coastal regions of temperate and Arctic seas worldwide, providing ecosystem services valued in the range of billions of dollars annually. Although local evidence suggests that kelp forests are increasingly threatened by a variety of stressors, no comprehensive global analysis of change in kelp abundances currently exists. Here, we build and analyze a global database of kelp time series spanning the past half-century to assess regional and global trends in kelp abundances. We detected a high degree of geographic variation in trends, with regional variability in the direction and magnitude of change far exceeding a small global average decline (instantaneous rate of change = −0.018 y−1). Our analysis identified declines in 38% of ecoregions for which there are data (−0.015 to −0.18 y−1), increases in 27% of ecoregions (0.015 to 0.11 y−1), and no detectable change in 35% of ecoregions. These spatially variable trajectories reflected regional differences in the drivers of change, uncertainty in some regions owing to poor spatial and temporal data coverage, and the dynamic nature of kelp populations. We conclude that although global drivers could be affecting kelp forests at multiple scales, local stressors and regional variation in the effects of these drivers dominate kelp dynamics, in contrast to many other marine and terrestrial foundation species.

    A simple method based on FAAS was developed for the sequential multi-element determination of Cu, Zn, Mn, Mg and Si in beverages and food supplements with successful results. The main absorption lines for Cu, Zn and Si and secondary lines for Mn and Mg were selected to carry out the measurements. The sample introduction was performed using a flow injection system. Using the choice of the absorption line wings, the upper limit of the linear range increased up to 110mgL(-1) for Mg, 200mgL(-1) for Si and 13mgL(-1) for Zn. The determination of the five elements was carried out, in triplicate, without the need of additional sample dilutions and/or re-measurements, using less than 3.5mL of sample to perform the complete analysis. The LODs were 0.008mgL(-1) for Cu, 0.017mgL(-1) for Zn, 0.011mgL(-1) for Mn, 0.16mgL(-1) for Si and 0.11mgL(-1) for Mg.

    In this study, we evaluated inhibitory potentials of popularly-consumed berries (bilberry, blueberry, cranberry, elderberry, and raspberry ketones) as herbal supplements on UGT1A1, UGT1A4, UGT1A6, UGT1A9, and UGT2B7 in vitro. We also investigated the potential herb-drug interaction via UGT1A1 inhibition by blueberry in vivo. We demonstrated that these berries had only weak inhibitory effects on the five UGTs. Bilberry and elderberry had no apparent inhibitions. Blueberry weakly inhibited UGT1A1 with an IC50 value of 62.4±4.40 μg/mL and a Ki value of 53.1 μg/mL. Blueberry also weakly inhibited UGT2B7 with an IC50 value of 147±11.1 μg/mL. In addition, cranberry weakly inhibited UGT1A9 activity (IC50=458±49.7 μg/mL) and raspberry ketones weakly inhibited UGT2B7 activity (IC50=248±28.2 μg/mL). Among tested berries, blueberry showed the lowest IC50 value in the inhibition of UGT1A1 in vitro. However, the co-administration of blueberry had no effect on the pharmacokinetics of irinotecan and its active metabolite, SN-38, which was mainly eliminated via UGT1A1, in vivo. Our data suggests that these five berries are unlikely to cause clinically significant herb-drug interactions mediated via inhibition of UGT enzymes involved in drug metabolism. These findings should enable an understanding of herb-drug interactions for the safe use of popularly-consumed berries.

    Kelp aquaculture activities occupy large nearshore areas with significant effects on sediment properties, primarily caused by the influence of the suspended kelp on local hydrodynamics. Changes in sediment composition and grain-size distributions were investigated prior to and following the commencement of kelp aquaculture activities in Heini Bay in eastern China. Seabed sediment types and the particulate matter in suspension during the kelp seeding and harvesting periods, and in sediment cores, were analyzed. While suspended sediment in the kelp aquaculture area was up to 20% organic material, sediment organic content on the seabed remained at similar levels as areas lacking aquaculture. The composition of the seabed sediment in the kelp aquaculture area became finer-grained by the capture of fine particles. Within the kelp aquaculture area, the sediments are poorly sorted and positively skewed, whereas at the shoreward and seaward of the aquaculture area the sediments are relatively coarse-grained, well-sorted and nearly symmetrically distributed. Therefore, the kelp aquaculture activities not only increase the fine particulate fraction in the sediments within the aquaculture area, but also result in similar deposits seaward of it, indicating that seabed erosion and accretion is also controlled by the sediment source and the hydrodynamic conditions. The analysis of sediment cores showed that kelp culturing refines the sediment by preferentially capturing particles in the 38-40 μm size class, while having no effect on the <32 μm fractions, as evidenced by the positive skew of the surficial sediments. The captured particle size class became well mixed into the sediment, thereby changing the composition of the sediment in the uppermost layer of the core, indicating the existence of continuous and stable hydrodynamic conditions within the kelp aquaculture area. The same effect was observed in the seabed sediments seaward of the aquaculture area.

    The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen. The groups were assigned to receive treatment diets as follows: i) basal diet (control), ii) basal diet plus 0.5% garlic powder (GP), iii) basal diet plus 0.5% pennywort powder (PW) and iv) 0.002% virginiamycin (VM). Birds were killed at day 42 and intestinal samples were collected to assess for Lactobacillus and Escherichia coli. The pectoralis profundus from chicken breast samples was obtained from 10 birds from each treatment group on day 42 and frozen at -20°C for further analyses. Fatty acid profile of breast muscles was determined using gas liquid chromatography. Feed intake and weight gain of broilers fed with GP, PW, and VM were significantly higher (p<0.05) compared to control. Feeding chicks GP, PW, and VM significantly reduced Escherichia coli count (p<0.05) while Lactobacillus spp count were significantly higher (p<0.05) in the gut when compared to control group on day 42. Supplemented diet containing pennywort increased the C18:3n-3 fatty acid composition of chickens' breast muscle. Garlic and pennywort may be useful in modulating broiler guts as they control the enteropathogens that help to utilize feed efficiently. This subsequently enhances the growth performances of broiler chickens.

    Kelp ecosystems form widespread underwater forests playing a major role in structuring the biodiversity at a regional scale. Some seaweeds such as Laminaria digitata are also economically important, being exploited for their alginate and iodine content. Although some studies have shown that kelp ecosystems are regressing and that multiple causes are likely to be at the origin of the disappearance of certain populations, the extent to which global climate change may play a role remains speculative. Here we show that many populations of L. digitata along European coasts are on the verge of local extinction due to a climate-caused increase in sea temperature. By modeling the spatial distribution of the seaweed, we evaluate the possible implications of global climate change for the geographical patterns of the species using temperature data from the Coupled Model Intercomparison Project phase 5 (CMIP5). Projections of the future range of L. digitata throughout the 21st century show large shifts in the suitable habitat of the kelp and a northward retreat of the southern limit of its current geographic distribution from France to Danish coasts and the southern regions of the United Kingdom. However, these projections depend on the intensity of warming. A medium to high warming is expected to lead to the extirpation of the species as early as the first half of the 21st century and there is high confidence that regional extinction will spread northwards by the end of this century. These changes are likely to cause the decline of species whose life cycle is closely dependent upon L. digitata and lead to the establishment of new ecosystems with lower ecological and economic values.

    2012-11-01

    Chinese herbal property theory (CHPT) is the fundamental characteristic of Chinese materia medica different from modern medicines. It reflects the herbal properties associated with efficacy and formed the early framework of four properties and five flavors in Shennong's Classic of Materia Medica. After the supplement and improvement of CHPT in the past thousands of years, it has developed a theory system including four properties, five flavors, meridian entry, direction of medicinal actions (ascending, descending, floating and sinking) and toxicity. However, because of the influence of philosophy about yin-yang theory and five-phase theory and the difference of cognitive approach and historical background at different times, CHPT became complex. One of the complexity features was the multiple methods for determining herbal property, which might include the inference from herbal efficacy, the thought of Chinese Taoist School and witchcraft, the classification thinking according to manifestations, etc. Another complexity feature was the multiselection associations between herbal property and efficacy, which indicated that the same property could be inferred from different kinds of efficacy. This paper analyzed these complexity features and provided the importance of cognitive approaches and efficacy attributes corresponding to certain herbal property in the study of CHPT.

    The marine marbled rockfish Sebastiscus marmoratus is dependent on kelp beds and rocks for survival and reproduction. We found that sound production and hearing sensitivity in S. marmoratus are closely matched in the frequency domain. We also found that the juvenile rockfish prefers the habitat of the larger macroalgae Sargassum horueri rather than the habitat containing the smaller algae Ulva pertusa where the adult rockfish prefers to live. Our underwater noise recording data from these two habitats indicate that their spectra of the background noise have different values. The results suggest that the acoustic cues may be critical for pelagic larvae when selecting the preferential habitat in which to settle.

  14. Large-scale geographic variation in distribution and abundance of Australian deep-water kelp forests.

    Directory of Open Access Journals (Sweden)

    Ezequiel M Marzinelli

    Full Text Available Despite the significance of marine habitat-forming organisms, little is known about their large-scale distribution and abundance in deeper waters, where they are difficult to access. Such information is necessary to develop sound conservation and management strategies. Kelps are main habitat-formers in temperate reefs worldwide; however, these habitats are highly sensitive to environmental change. The kelp Ecklonia radiate is the major habitat-forming organism on subtidal reefs in temperate Australia. Here, we provide large-scale ecological data encompassing the latitudinal distribution along the continent of these kelp forests, which is a necessary first step towards quantitative inferences about the effects of climatic change and other stressors on these valuable habitats. We used the Autonomous Underwater Vehicle (AUV facility of Australia's Integrated Marine Observing System (IMOS to survey 157,000 m2 of seabed, of which ca 13,000 m2 were used to quantify kelp covers at multiple spatial scales (10-100 m to 100-1,000 km and depths (15-60 m across several regions ca 2-6° latitude apart along the East and West coast of Australia. We investigated the large-scale geographic variation in distribution and abundance of deep-water kelp (>15 m depth and their relationships with physical variables. Kelp cover generally increased with latitude despite great variability at smaller spatial scales. Maximum depth of kelp occurrence was 40-50 m. Kelp latitudinal distribution along the continent was most strongly related to water temperature and substratum availability. This extensive survey data, coupled with ongoing AUV missions, will allow for the detection of long-term shifts in the distribution and abundance of habitat-forming kelp and the organisms they support on a continental scale, and provide information necessary for successful implementation and management of conservation reserves.

    To probe the effect of kelp waste extracts (KWE) combined with acetate on biochemical composition of Chlorella sorokiniana, the cultures were performed under independent/combined treatment of KWE and acetate. The results showed that high cell density and biomass were obtained by KWE combined with acetate treatments, whose biomass productivity increased by 79.69-102.57% and 20.04-35.32% compared with 3.0gL(-1) acetate and KWE treatments respectively. The maximal neutral lipid per cell and lipid productivity were gained in KWE combined with 3.0gL(-1) acetate treatment, which increased by 16.32% and 129.03% compared with 3.0gL(-1) acetate, and 253.35% and 70.74% compared with KWE treatment. Meanwhile, C18:3n3 and C18:2n6c contents were reduced to 4.90% and 11.88%, whereas C16:0 and C18:1n9c were improved to 28.71% and 37.76%. Hence, supplementing appropriate acetate in KWE cultures is supposed to be a great potential method for large-scale cultivation of C. sorokiniana to generate biofuel. Copyright © 2016 Elsevier Ltd.

    Herbal and dietary supplement use is common. Most marketed products consist of complex mixtures. Although they are perceived as safe, instances of hepatotoxicity attributable to these products underscore their potential for injury, but the exact component that is responsible for injury is difficult to discern. The lenient regulatory environment in the United States, which opens the possibility of adulteration and contamination, adds to the challenge of disease attribution. Although many different herbal and dietary supplements have been reported to cause liver injury, in the United States, products used for bodybuilding and weight loss are the most commonly implicated.

    To investigate whether Vigconic 28 (VI-28), a Yang-invigorating Chinese herbal formula, could affect survival of aging animals, male and female C57BL/6J mice were given a VI-28-supplemented diet (0.05 and 0.5%, wt/wt) starting at 36 weeks of age, until death. VI-28 dietary supplementation at 0.05% significantly increased median lifespans of both male and female mice as compared to controls. Survival enhancement was associated with protection against age-associated impairments in mitochondrial antioxidant status and functional ability in various tissues. In conclusion, VI-28 could retard the aging process in mice, probably by mitigating age-associated declines in mitochondrial antioxidant status and functional ability in tissues.

    2006-06-01

    Full Text Available Abstract Background There are limited data on the extent of women's use of herbal medicines during pregnancy, despite the fact that knowledge of the potential benefits or harms of many of these products is sparse, particularly with respect to their use in pregnancy. We aimed to measure the prevalence of herbal medicine use in a group of pregnant women attending a public tertiary maternity hospital in Melbourne, Australia. Secondary aims were to explore why women took the herbal medicine, where they received advice, what form the supplements took and if they perceived the supplements to be helpful. Methods Consecutive pregnant women were approached in the antenatal clinic and the birth centre at around 36–38 weeks gestation. A questionnaire was developed and self-administered in English, as well as being translated into the four most common languages of women attending the hospital: Cantonese, Vietnamese, Turkish and Arabic. Back translation into English was undertaken by different professional translators to verify accuracy of both words and concepts. Data collected included demographic information, model of pregnancy care and herbal supplement use. Descriptive statistics were used initially, with stratified and regression analysis to compare sub-groups. Results Of 705 eligible women, 588 (83% agreed to participate. Of these, 88 (15% completed the questionnaire in a language other than English. Thirty-six percent of women took at least one herbal supplement during the current pregnancy. The most common supplements taken were raspberry leaf (14%, ginger (12% and chamomile (11%. Women were more likely to take herbal supplements if they were older, tertiary educated, English speaking, non-smokers and primiparous. Conclusion Use of herbal supplements in pregnancy is likely to be relatively high and it is important to ascertain what supplements (if any women are taking. Pregnancy care providers should be aware of the common herbal supplements used

  20. Kelp growth on an ocean farm in relation to fertilizing

    Results of fertilizing experiments on the test farm supported previous evidence that low macronutrient supplies limit kelp growth in offshore surface water. Enhanced N contents of blade tissues from adult and juvenile plants and enhanced growth of juvenile plants indicates that artificially upwelled deep water could provide a suitable source of nutrients. However, measurement of harvestable production depends on our ability to prevent damage to plants by currents and abrasion, which would be edge effects on a large-scale ocean farm. Three adult Macrocystis plants have been held successfully on the test farm for one year by locating them away from major structural elements. At least ten times that many plants, suitably protected and fertilized with deep water, are necessary to accomplish the immediate goal of determining yield. The test farm is now being redesigned to meet these requirements.

  2. Herbal Hepatotoxicity: Clinical Characteristics and Listing Compilation.

    Science.gov (United States)

    2016-04-27

    Herb induced liver injury (HILI) and drug induced liver injury (DILI) share the common characteristic of chemical compounds as their causative agents, which were either produced by the plant or synthetic processes. Both, natural and synthetic chemicals are foreign products to the body and need metabolic degradation to be eliminated. During this process, hepatotoxic metabolites may be generated causing liver injury in susceptible patients. There is uncertainty, whether risk factors such as high lipophilicity or high daily and cumulative doses play a pathogenetic role for HILI, as these are under discussion for DILI. It is also often unclear, whether a HILI case has an idiosyncratic or an intrinsic background. Treatment with herbs of Western medicine or traditional Chinese medicine (TCM) rarely causes elevated liver tests (LT). However, HILI can develop to acute liver failure requiring liver transplantation in single cases. HILI is a diagnosis of exclusion, because clinical features of HILI are not specific as they are also found in many other liver diseases unrelated to herbal use. In strikingly increased liver tests signifying severe liver injury, herbal use has to be stopped. To establish HILI as the cause of liver damage, RUCAM (Roussel Uclaf Causality Assessment Method) is a useful tool. Diagnostic problems may emerge when alternative causes were not carefully excluded and the correct therapy is withheld. Future strategies should focus on RUCAM based causality assessment in suspected HILI cases and more regulatory efforts to provide all herbal medicines and herbal dietary supplements used as medicine with strict regulatory surveillance, considering them as herbal drugs and ascertaining an appropriate risk benefit balance.

    2009-03-01

    Tomato mosaic virus (ToMV) encodes a movement protein (MP) that is necessary for virus cell-to-cell movement. We have demonstrated previously that KELP, a putative transcriptional coactivator of Arabidopsis thaliana, and its orthologue from Brassica campestris can bind to ToMV MP in vitro. In this study, we examined the effects of the transient over-expression of KELP on ToMV infection and the intracellular localization of MP in Nicotiana benthamiana, an experimental host of the virus. In co-bombardment experiments, the over-expression of KELP inhibited virus cell-to-cell movement. The N-terminal half of KELP (KELPdC), which had been shown to bind to MP, was sufficient for inhibition. Furthermore, the over-expression of KELP and KELPdC, both of which were co-localized with ToMV MP, led to a reduction in the plasmodesmal association of MP. In the absence of MP expression, KELP was localized in the nucleus and the cytoplasm by the localization signal in its N-terminal half. It was also shown that ToMV amplified normally in protoplasts prepared from leaf tissue that expressed KELP transiently. These results indicate that over-expressed KELP interacts with MP in vivo and exerts an inhibitory effect on MP function for virus cell-to-cell movement, but not on virus amplification in individual cells.

    Kelp forests represent a major habitat type in coastal waters worldwide and their structure and distribution is predicted to change due to global warming. Despite their ecological and economical importance, there is still a lack of reliable spatial information on their abundance and distribution. In recent years, various hydroacoustic mapping techniques for sublittoral environments evolved. However, in turbid coastal waters, such as off the island of Helgoland (Germany, North Sea), the kelp vegetation is present in shallow water depths normally excluded from hydroacoustic surveys. In this study, single beam survey data consisting of the two seafloor parameters roughness and hardness were obtained with RoxAnn from water depth between 2 and 18 m. Our primary aim was to reliably detect the kelp forest habitat with different densities and distinguish it from other vegetated zones. Five habitat classes were identified using underwater-video and were applied for classification of acoustic signatures. Subsequently, spatial prediction maps were produced via two classification approaches: Linear discriminant analysis (LDA) and manual classification routine (MC). LDA was able to distinguish dense kelp forest from other habitats (i.e. mixed seaweed vegetation, sand, and barren bedrock), but no variances in kelp density. In contrast, MC also provided information on medium dense kelp distribution which is characterized by intermediate roughness and hardness values evoked by reduced kelp abundances. The prediction maps reach accordance levels of 62% (LDA) and 68% (MC). The presence of vegetation (kelp and mixed seaweed vegetation) was determined with higher prediction abilities of 75% (LDA) and 76% (MC). Since the different habitat classes reveal acoustic signatures that strongly overlap, the manual classification method was more appropriate for separating different kelp forest densities and low-lying vegetation. It became evident that the occurrence of kelp in this area is not

    Kelps are founding species of temperate marine ecosystems, living in intertidal coastal areas where they are often challenged by generalist and specialist herbivores. As most sessile organisms, kelps develop defensive strategies to restrain grazing damage and preserve their own fitness during interactions with herbivores. To decipher some inducible defense and signaling mechanisms, we carried out metabolome and transcriptome analyses in two emblematic kelp species, Lessonia spicata from South Pacific coasts and Laminaria digitata from North Atlantic, when challenged with their main specialist herbivores. Mass spectrometry based metabolomics revealed large metabolic changes induced in these two brown algae following challenges with their own specialist herbivores. Targeted metabolic profiling of L. spicata further showed that free fatty acid (FFA) and amino acid (AA) metabolisms were particularly regulated under grazing. An early stress response was illustrated by the accumulation of Sulphur containing amino acids in the first twelve hours of herbivory pressure. At latter time periods (after 24 hours), we observed FFA liberation and eicosanoid oxylipins synthesis likely representing metabolites related to stress. Global transcriptomic analysis identified sets of candidate genes specifically induced by grazing in both kelps. qPCR analysis of the top candidate genes during a 48-hours time course validated the results. Most of these genes were particularly activated by herbivore challenge after 24 hours, suggesting that transcriptional reprogramming could be operated at this time period. We demonstrated the potential utility of these genes as molecular markers for herbivory by measuring their inductions in grazed individuals of field harvested L. digitata and L. spicata. By unravelling the regulation of some metabolites and genes following grazing pressure in two kelps representative of the two hemispheres, this work contributes to provide a set of herbivore

  11. Dietary supplements: What's in a name? What's in the bottle?

    Science.gov (United States)

    Marcus, Donald M

    2016-01-01

    The Dietary Supplement Health and Education Act of 1994 (DSHEA), which arbitrarily classified herbals and other medicinal products as dietary supplements, obscured fundamental differences between two classes of products. Authentic supplements to the diet, such as multivitamins or calcium, have nutritional value and are safe. Herbals are used worldwide as medicines, they do not supplement the diet, they may cause severe adverse events, and they should be regulated as medicines. DSHEA also prevented the Food and Drug Administration (FDA) from effectively regulating herbal supplements as medicines. One consequence of weak FDA regulatory oversight is the poor quality of herbals. FDA inspections of manufacturing facilities have revealed violations of good manufacturing practices in over half of facilities inspected, including unsanitary conditions and lack of product specifications. Moreover, many "all natural" herbals marketed for weight loss, enhancement of sexual health and improving sports performance are adulterated with prescription and over-the-counter medications that have caused adverse cardiovascular events. New procedures to authenticate the identity of plants used in herbals will neither detect adulteration by medications nor provide assurance of appropriate pharmacological activity or safety. Nonvitamin, nonmineral "supplements" should be regulated as medicines, but revision or repeal of DSHEA faces strong opposition in Congress. The marketing of botanical supplements is based on unfounded claims that they are safe and effective. Health professionals need to inform patients and the public that there is no reason to take herbal medicines whose composition and benefits are unknown, and whose risks are evident.

    Kelp forests are among the world's most productive marine ecosystems, yet little is known about their biogeochemistry. This study presents a 14-month time series (July 2013-August 2014) of surface and benthic dissolved inorganic carbon and total alkalinity measurements, along with accompanying hydrographic measurements, from six locations within a central California kelp forest. We present ranges and patterns of variability in carbonate chemistry, including pH (7.70-8.33), pCO2 (172-952 µatm), and the aragonite saturation state, ΩAr (0.94-3.91). Surface-to-bottom gradients in CO2 system chemistry were as large as the spatial gradients throughout the bottom of the kelp forest. Dissolved inorganic carbon variability was the main driver of the observed CO2 system variability. The majority of spatial variability in the kelp forest can be explained by advection of cold, dense high-CO2 waters into the bottom of the kelp forest, with deeper sites experiencing high-CO2 conditions more frequently. Despite the strong imprint of advection on the biogeochemical variability of the kelp forest, surface waters were undersaturated with CO2 in the spring through fall, indicative of the strong role of photosynthesis on biogeochemical variability. We emphasize the importance of spatially distributed measurements for developing a process-based understanding of kelp forest ecosystem function in a changing climate.

    Herbs and other botanicals have been used in different cultures with medicinal and dietary purposes for centuries. Contrary to the belief of being natural and safe products, their hepatotoxic potential is recognized in several studies worldwide, and represent a health problem that deserves greater attention. The reported prevalence of hepatotoxicity associated with botanicals is variable and depends on various factors such as population, period and design of the study. There have been reports of a total of 60 products with herbal medicinal and dietary purposes, which may cause liver damage; however, the pathophysiological mechanisms involved are not fully elucidated. Their clinical and histological features, not unlike liver injury associated with drugs in most patients, have a pattern of hepatocellular injury. Diagnosis is by exclusion, and represents a clinical challenge. It is essential the clinical suspicion and the differential diagnosis with other acute and chronic conditions. Hence, future researches are aimed at improving existing diagnostic methods and introducing new toxicological, genetic and immunological technologies. Treatment is complex and presents a challenge for the specialist, as there are no antidotes. Management based on the discontinued use of the product and in the symptomatic treatment, decreases the progression to an acute fulminant hepatic failure.

  15. Connectivity of the habitat-forming kelp, Ecklonia radiata within and among estuaries and open coast.

    2013-01-01

    With marine protected areas being established worldwide there is a pressing need to understand how the physical setting in which these areas are placed influences patterns of dispersal and connectivity of important marine organisms. This is particularly critical for dynamic and complex nearshore marine environments where patterns of genetic structure of organisms are often chaotic and uncoupled from broad scale physical processes. This study determines the influence of habitat heterogeneity (presence of estuaries) on patterns of genetic structure and connectivity of the common kelp, Ecklonia radiata. There was no genetic differentiation of kelp between estuaries and the open coast and the presence of estuaries did not increase genetic differentiation among open coast populations. Similarly, there were no differences in level of inbreeding or genetic diversity between estuarine and open coast populations. The presence of large estuaries along rocky coastlines does not appear to influence genetic structure of this kelp and factors other than physical heterogeneity of habitat are likely more important determinants of regional connectivity. Marine reserves are currently lacking in this bioregion and may be designated in the future. Knowledge of the factors that influence important habitat forming organisms such as kelp contribute to informed and effective marine protected area design and conservation initiatives to maintain resilience of important marine habitats.

    Sex discriminating genetic markers are commonly used to facilitate breeding programs in economically and ecologically important animal and plant species. However, despite their considerable economic and ecological value, the development of sex markers for kelp species has been very limited. In this study, we used the recently described sequence of the sex determining region (SDR) of the brown algal model Ectocarpus to develop novel DNA-based sex-markers for three commercially relevant kelps: Laminaria digitata, Undaria pinnatifida and Macrocystis pyrifera. Markers were designed within nine protein coding genes of Ectocarpus male and female (U/V) sex chromosomes and tested on gametophytes of the three kelp species. Seven primer pairs corresponding to three loci in the Ectocarpus SDR amplified sex-specific bands in the three kelp species, yielding at least one male and one female marker for each species. Our work has generated the first male sex-specific markers for L. digitata and U. pinnatifida, as well as the first sex markers developed for the genus Macrocystis. The markers and methodology presented here will not only facilitate seaweed breeding programs but also represent useful tools for population and demography studies and provide a means to investigate the evolution of sex determination across this largely understudied eukaryotic group.

Our work has generated the first male sex-specific markers for L. digitata and U. pinnatifida, as well as the first sex markers developed for the genus Macrocystis. The markers and methodology presented here will not only facilitate seaweed breeding programs but also represent useful tools for population and demography studies and provide a means to investigate the evolution of sex determination across this largely understudied eukaryotic group.

    Concern on the impacts of ocean acidification on calcifiers, such as bivalves, sea urchins, and foraminifers, has led to efforts to understand the controls on pH in their habitats, which include kelp forests and seagrass meadows. The metabolism of these habitats can lead to diel fluctuation in pH with increases during the day and declines at night, suggesting no net effect on pH at time scales longer than daily. We examined the capacity of subarctic and Arctic kelps to up-regulate pH in situ and experimentally tested the role of photoperiod in determining the capacity of Arctic macrophytes to up-regulate pH. Field observations at photoperiods of 15 and 24 hours in Greenland combined with experimental manipulations of photoperiod show that photoperiods longer than 21 hours, characteristic of Arctic summers, are conducive to sustained up-regulation of pH by kelp photosynthesis. We report a gradual increase in pH of 0.15 units and a parallel decline in pCO2 of 100 parts per million over a 10-day period in an Arctic kelp forest over midsummer, with ample scope for continued pH increase during the months of continuous daylight. Experimental increase in CO2 concentration further stimulated the capacity of macrophytes to deplete CO2 and increase pH. We conclude that long photoperiods in Arctic summers support sustained up-regulation of pH in kelp forests, with potential benefits for calcifiers, and propose that this mechanism may increase with the projected expansion of Arctic vegetation in response to warming and loss of sea ice.

  5. Active and passive migration in boring isopods Limnoria spp. (Crustacea, Peracarida) from kelp holdfasts

    Miranda, Leonardo; Thiel, Martin

    2008-10-01

    Many boring isopods inhabit positively buoyant substrata (wood and algae), which float after detachment, permitting passive migration of inhabitants. Based on observations from previous studies, it was hypothesized that juvenile, subadult and male isopods migrate actively, and will rapidly abandon substrata after detachment. In contrast, reproductive females and small offspring were predicted to remain in floating substrata and thus have a high probability to disperse passively via rafting. In order to test this hypothesis, a colonization and an emigration experiment were conducted with giant kelp ( Macrocystis integrifolia), the holdfasts of which are inhabited by boring isopods from the genus Limnoria. A survey of benthic substrata in the kelp forest confirmed that limnoriids inhabited the holdfasts and did not occur in holdfast-free samples. Results of the colonization experiment showed that all life history stages of the boring isopods immigrated into young, largely uncolonized holdfasts, and after 16 weeks all holdfasts were densely colonized. In the emigration experiment, all life history stages of the isopods rapidly abandoned the detached holdfasts — already 5 min after detachment only few individuals remained in the floating holdfasts. After this initial rapid emigration of isopods, little changes in isopod abundance occurred during the following 24 h, and at the end of the experiment some individuals of all life history stages still remained in the holdfasts. These results indicate that all life history stages of Limnoria participate in both active migration and passive dispersal. It is discussed that storm-related dynamics within kelp forests may contribute to intense mixing of local populations of these burrow-dwelling isopods, and that most immigrants to young holdfasts probably are individuals emigrating from old holdfasts detached during storm events. The fact that some individuals of all life history stages and both sexes remain in floating

    Herbal medicine products represent a common therapeutic approach in the East and are gaining increasing popularity in Western countries. They are unjustifiably considered to be side-effect free; on the contrary, severe toxicity, including catastrophic hepatic injury has been reported in association with their use. Vigilance isrequired from both physicians and the general public. Physicians should always suspect herbal medicines when evaluating a patient with unexplained liver injury. Regulation standards for herbal products need to be reconsidered, so that the efficacy and safety of these products have been clearly demonstrated before they enter the markets.

    For the past few decades, compounds from natural sources have been gaining importance because of the vast chemical diversity they offer. This has led to phenomenal increase in the demand for herbal medicines in the last two decades and need has been felt for ensuring the quality, safety, and efficacy of herbal drugs. Phytochemical evaluation is one of the tools for the quality assessment, which include preliminary phytochemical screening, chemoprofiling, and marker compound analysis using modern analytical techniques. High-performance thin-layer chromatography (HPTLC) has been emerged as an important tool for the qualitative, semiquantitative, and quantitative phytochemical analysis of the herbal drugs and formulations. This includes developing TLC fingerprinting profiles and estimation of biomarkers. This review has an attempt to focus on the theoretical considerations of HPTLC and some examples of herbal drugs and formulations analyzed by HPTLC.

    Full Text Available Plants are natural producers of chemical substances, providing potential treatment of human ailments since ancient times. Some herbal chemicals in medicinal plants of traditional and modern medicine carry the risk of herb induced liver injury (HILI with a severe or potentially lethal clinical course, and the requirement of a liver transplant. Discontinuation of herbal use is mandatory in time when HILI is first suspected as diagnosis. Although herbal hepatotoxicity is of utmost clinical and regulatory importance, lack of a stringent causality assessment remains a major issue for patients with suspected HILI, while this problem is best overcome by the use of the hepatotoxicity specific CIOMS (Council for International Organizations of Medical Sciences scale and the evaluation of unintentional reexposure test results. Sixty five different commonly used herbs, herbal drugs, and herbal supplements and 111 different herbs or herbal mixtures of the traditional Chinese medicine (TCM are reported causative for liver disease, with levels of causality proof that appear rarely conclusive. Encouraging steps in the field of herbal hepatotoxicity focus on introducing analytical methods that identify cases of intrinsic hepatotoxicity caused by pyrrolizidine alkaloids, and on omics technologies, including genomics, proteomics, metabolomics, and assessing circulating micro-RNA in the serum of some patients with intrinsic hepatotoxicity. It remains to be established whether these new technologies can identify idiosyncratic HILI cases. To enhance its globalization, herbal medicine should universally be marketed as herbal drugs under strict regulatory surveillance in analogy to regulatory approved chemical drugs, proving a positive risk/benefit profile by enforcing evidence based clinical trials and excellent herbal drug quality.

  13. Blade life span, structural investment, and nutrient allocation in giant kelp.

    2016-10-01

    The turnover of plant biomass largely determines the amount of energy flowing through an ecosystem and understanding the processes that regulate turnover has been of interest to ecologists for decades. Leaf life span theory has proven useful in explaining patterns of leaf turnover in relation to resource availability, but the predictions of this theory have not been tested for macroalgae. We measured blade life span, size, thickness, nitrogen content, pigment content, and maximum photosynthetic rate (P max) in the giant kelp (Macrocystis pyrifera) along a strong resource (light) gradient to test whether the predictions of leaf life span theory applied to this alga. We found that shorter blade life spans and larger blade areas were associated with increased light availability. In addition, nitrogen and P max decreased with blade age, and their decrease was greater in shorter lived blades. These observations are generally consistent with patterns observed for higher plants and the prevailing theory of leaf life span. By contrast, variation observed in pigments of giant kelp was inconsistent with that predicted by leaf life span theory, as blades growing in the most heavily shaded portion of the forest had the lowest chlorophyll content. This result may reflect the dual role of macroalgal blades in carbon fixation and nutrient absorption and the ability of giant kelp to modify blade physiology to optimize the acquisition of light and nutrients. Thus, the marine environment may place demands on resource acquisition and allocation that have not been previously considered with respect to leaf life span optimization.

    As marine management is moving towards the practice of protecting static areas, it is 44 important to make sure protected areas capture and protect persistent populations. Rocky reefs in 45 many temperate areas worldwide serve as habitat for canopy forming macroalgae and these 46 structure forming species of kelps (order Laminariales) often serve as important habitat for a great 47 diversity of species. Macrocystis pyrifera is the most common canopy forming kelp species found 48 along the coast of California but the distribution and abundance of M. pyrifera varies in space and 49 time. The purpose of this study is to determine what environmental parameters are correlated with 50 the spatial and temporal persistence of M. pyrifera along the central coast of California and how 51 well those environmental parameters can be used to predict areas where M. pyrifera is more likely 52 to persist. Nine environmental variables considered in this study included depth of the seafloor, 53 structure of the rocky reef, proportion of rocky reef, size of kelp patch, biomass of kelp within a 54 patch, distance from the edge of a kelp patch, sea surface temperature, wave orbital velocities, and 55 population connectivity of individual kelp patches. Using a generalized linear mixed effects model 56 (GLMM), the persistence of M. pyrifera was significantly associated with seven of the nine 57 variables considered: depth, complexity of the rocky reef, proportion of rock, patch biomass, 58 distance from the edge of a patch, population connectivity, and wave-orbital velocities. These 59 seven environmental variables were then used to predict the persistence of kelp across the central 60 coast and these predictions were compared to a reserved dataset of M. pyrifera persistence, which 61 was not used in the creation of the GLMM. The environmental variables were shown to accurately 62 predict the persistence of M. pyrifera within the central coast of California (r = 0.71, Pmanagement of these

    Bivalves and seaweeds are important cleaners that are widely used in integrated multi-trophic aquaculture (IMTA) systems. A beneficial relationship between seaweed and bivalve in the seaweed-based IMTA system has been confirmed, but the trophic importance of seaweed-derived particulate organic materials to the co-cultured bivalve is still unclear. We evaluated the trophic importance of the kelp Saccharina japonica to the co-cultured scallop Chlamys farreri in a typical IMTA farm in Sungo Bay (Weihai, North China). The dynamics of detritus carbon in the water were monitored during the culturing period. The proportion of kelp-derived organic matter in the diet of the co-cultured scallop was assessed via the stable carbon isotope method. Results showed that the detritus carbon in the water ranged from 75.52 to 265.19 μg/L, which was 25.6% to 73.8% of total particulate organic carbon (TPOC) during the study period. The amount of detritus carbon and its proportion in the TPOC changed throughout the culture cycle of the kelp. Stable carbon isotope analysis showed that the cultured scallop obtained 14.1% to 42.8% of its tissue carbon from the kelp, and that the percentages were closely correlated with the proportion of detritus carbon in the water ( F =0.993, P= 0.003). Evaluation showed that for 17 000 tons (wet weight) of annual scallop production, the kelp contributed about 139.3 tons of carbon (535.8 tons of dry mass). This confirms that cultured kelp plays a similar trophic role in IMTA systems as it does in a natural kelp bed. It is a major contributor to the detritus pool and supplies a vital food source to filter-feeding scallops in the IMTA system, especially during winter and early spring when phytoplankton are scarce.

    To evaluate the effect of various herbal adaptogens such as shade-dried powders of Withania somnifera, Ocimum sanctum, Asperagus recemosus, Andrographis paniculata, Asphaltum panjabinum (Shilajith), Gymnema sylvestre, Spirulina platensis, and Panex ginseng on cadmium (Cd)-induced oxidative stress and its accumulation in broiler chicken. A total of 80 male broiler chicks of day old age were randomly assigned to 10 equal groups. Group 1 birds were fed with basal diet throughout the experiment (1-42 days). Group 2-10 chicks were fed with basal diet containing cadmium at 100 ppm from day 1 to day 28 (4 weeks). From 29(th) to 42(nd) day (2 weeks), basal diet alone was fed to group 2 chicks which acted as toxic control and group 3-10 birds were fed with feed containing 0.1% powder of W. somnifera, O. sanctum, Aspe. recemosus, An. paniculata, Asph. panjabinum (Shilajith), G. sylvestre, S. platensis, and P. ginseng, respectively. Body weight gain, levels of non-enzymatic antioxidants such as reduced glutathione (GSH), lipid peroxidation markers such as thiobarbituric acid reacting substances (TBARS), liver functional markers such as serum alanine transaminase (ALT), kidney functional markers such as blood urea nitrogen (BUN) and serum creatinine and concentration of cadmium in liver and kidney were investigated. Body weight gains were significantly decreased in birds of groups 2-10 compared to group 1 at the end of 4(th) week. Supplementation of various medicinal herbs in feed after 4(th) week significantly improved the body weight gain compared to that in group 2 chicks. The increase in TBARS and decrease in GSH concentrations of liver and kidney tissues in cadmium intoxicated birds were significantly reversed by the above-said herbs. The liver and kidney functional markers were also restored to normal levels. Highest concentration of cadmium was found accumulated in kidney, followed by liver in birds of group 2. Herbal supplementation in groups 3-10 prevented Cd

    Full Text Available Natural remedies, such as those based on traditional Chinese medicines, have become more popular also in western countries over the last 10 years. The composition of these herbal products is largely unknown and difficult to determine. Moreover, since plants respond to their environment changing the metabolome, the composition of plant material can vary depending on the plant growth conditions.However, there is a growing need of a deeper knowledge on such natural remedies also in view of the growing number of reports of toxicity following the consumption of herbal supplements. Untargeted metabolomics is a useful approach for the simultaneous analysis of many compounds in herbal products. In particular, liquid chromatography/mass spectrometry (LC-MS can determine presence, amount and sometime structures of plant metabolites in complex herbal mixtures, with significant advantages over techniques such as nuclear magnetic resonance (NMR spectroscopy and gas chromatography/mass spectrometry (GC-MS.

    Full Text Available Herbal drugs are defined as any form of a plant or plant product that contains a single herb or combinations of herbs that are believed to have complementary effects. Although they are considered to be safe, because they are natural, they may have various adverse effects, and may interact with other herbal products or conventional drugs. These interactions are especially important for drugs with narrow therapeutic indices.In the present study, pharmacokinetic and pharmacodynamic interactions of some most commanly used herbals (St John's wort, ginkgo biloba, ginseng, ginger, garlic, echinacea, ephedra and valerian with the conventional drugs were reviewed. Pharmacokinetic interactions involve mainly induction or inhibition of the cytochrome P450 isozymes and p-glycoproteins by the herbal medicine, thus changing the absorption and/or elimination rate and consequently the efficacy of the concommitantly used drugs. St John's wort, a well known enzyme inducer, decreases the efficacy of most of the other drugs that are known to be the substrates of these enzymes.Pharmacodynamic interactions may be due to additive or synergistic effects which results in enhanced effect or toxicity, or herbal medicines with antagonistic properties reduce drug efficacy and result in therapeutic failure. For exampla, St John's wort may have synergistic effects with other antidepressant drugs used by the patient, resulting in increased CNS effects.Herbals like ginseng, ginkgo, garlic, ginger were reported to increase bleeding time, thus potentiating the effect of anticoagulant and antithrombotic agents. In conclusion, patients should be warned against the interaction between the herbal products and conventional medicines.

In present days the use of such product has increased and choice of shades of color, texture and luster have been changed and become wider. This can be observed from the fact that lipsticks are marked in hundreds of shades of colors to satisfy the demand of women. The present investigation was done to formulate herbal lipstick, since lipsticks are one of the key cosmetics to be used by the women. Attempt was also made to evaluate the formulated herbal lipstick. The word herbal is a symbol of safety in contrast to the synthetic one which has adverse effects on human health. Herbal preparations viz., herbal tablets, herbal tonics, herbal paste, herbal shampoo, herbal sindhur, herbal contraceptives and herbal lipstick has become popular among the consumer herbal medicines represent the fastest growing segment to heal the various ailments. Human being have been using herbs for different purpose like food, medicine, beatifying with advancement of science & technology use of natural things including plant has been reduced except for food, vegetarian takes plant& plant only. However there is resurgence of use of herbs both as drug and cosmetics. Due to various adverse effects of available synthetic preparation the present work was conceived by us to formulate a herbal lipstick having minimal or no side effects which will extensively used by the women of our communities with great surety and satisfaction.

    Full Text Available Background: The acceptability of herbal formulations as therapeutic agents for numerous diseases has reached to its brim in the latest phytomedicine scenario. Since herbal medicinal products are complex mixtures from biological sources, regulations are necessary to guarantee the constant quality and quantity in order to break the unanimous myth related to herbal medicines consumption. Although the pharmacovigilance program in India has spread its roots in the field of medicines, amazingly there has been no benchmark regulations set up in the herbal segments. Aim: As per the latest regulatory scenario, the herbal drug regulation or herbal pharmacovigilance of India is lagging very much behind the highly regulated international herbal markets. The present article serves as a reminder of the fact that it is the high time for the Indian drug regulators to tame the herbal drug market since India has emerged as resourceful of enormous herbal medicines with full proof folk knowledge but is still lacking the specific legislative criteria to establish these herbal products as "medicine." Conclusion: This systemic herbal pharmacovigilance will definitely boost up not only the herbal market trend, but also the confidence about using of botanical medicines regarding their safe and rationale use within the ambit of pharmacotherapy.

    Fishing can trigger trophic cascades that alter community structure and dynamics and thus modify ecosystem attributes. We combined ecological data of sea urchin and macroalgal abundance with fishery data of spiny lobster (Panulirus interruptus) landings to evaluate whether: (1) patterns in the abundance and biomass among lobster (predator), sea urchins (grazer), and macroalgae (primary producer) in giant kelp forest communities indicated the presence of top-down control on urchins and macroalgae, and (2) lobster fishing triggers a trophic cascade leading to increased sea urchin densities and decreased macroalgal biomass. Eight years of data from eight rocky subtidal reefs known to support giant kelp forests near Santa Barbara, CA, USA, were analyzed in three-tiered least-squares regression models to evaluate the relationships between: (1) lobster abundance and sea urchin density, and (2) sea urchin density and macroalgal biomass. The models included reef physical structure and water depth. Results revealed a trend towards decreasing urchin density with increasing lobster abundance but little evidence that urchins control the biomass of macroalgae. Urchin density was highly correlated with habitat structure, although not water depth. To evaluate whether fishing triggered a trophic cascade we pooled data across all treatments to examine the extent to which sea urchin density and macroalgal biomass were related to the intensity of lobster fishing (as indicated by the density of traps pulled). We found that, with one exception, sea urchins remained more abundant at heavily fished sites, supporting the idea that fishing for lobsters releases top-down control on urchin grazers. Macroalgal biomass, however, was positively correlated with lobster fishing intensity, which contradicts the trophic cascade model. Collectively, our results suggest that factors other than urchin grazing play a major role in controlling macroalgal biomass in southern California kelp forests, and

  5. The importance of progressive senescence in the biomass dynam of giant kelp (Macrocystis pyrifera).

    Temporal variation in primary producer biomass has profound effects on the structure and function of the surrounding ecological community. The giant kelp (Macrocystis pyrifera) exhibits strong intra-annual variation in biomass density, which is better explained by the demographic rates of fronds than by those of whole plants. To better understand the processes controlling the dynamics of giant kelp fronds we collected monthly time-series data of frond initiation and survival. These data were used to determine how frond loss and frond initiation rates were predicted by factors thought to affect the growth and survival of Macrocystis, including external environmental factors (i.e., wave height, day length, temperature, nutrient concentration, and neighborhood density) and intrinsic biological characteristics (i.e., frond age, plant size, and nutritional status). Our results revealed that frond dynamics were better explained by intrinsic biological processes rather than external environmental factors. A metric of frond age structure that incorporated progressive senescence was the best predictor of frond loss rate, accounting for 58% of the explained variation in frond loss. A similar analysis revealed that frond age structure was also the single best predictor of frond initiation rate, accounting for 46% of the explained variation. To further examine the importance of senescence in biomass dynamics, we used frond age-dependent mortality and frond initiation rates to predict biomass in subsequent months and found that the model explained 73% of the observed variation in biomass at our sites. Vegetation dynamics of many species including giant kelp are often considered largely in the context of external controls on resource availability and physical disturbance. Our results indicate that investigations of the processes controlling vegetation dynamics may benefit greatly from the inclusion of intrinsic biological factors such as age-dependent mortality and growth, which

    Mechanisms of inorganic carbon assimilation were investigated in the four deep-water kelps inhabiting sea bottoms at the Strait of Gibraltar; these species are distributed at different depths (Saccorhiza polysiches at shallower waters, followed by Laminaria ochroleuca, then Phyllariopsis brevipes and, at the deepest bottoms, Phyllariopsis purpurascens). To elucidate the capacity to use HCO3(-) as a source of inorganic carbon for photosynthesis in the kelps, different experimental approaches were used. Specifically, we measured the irradiance-saturated gross photosynthetic rate versus pH at a constant dissolved inorganic carbon (DIC) concentration of 2 mM, the irradiance-saturated apparent photosynthesis (APS) rate versus DIC, the total and the extracellular carbonic anhydrase (CAext), the observed and the theoretical photosynthetic rates supported by the spontaneous dehydration of HCO3(-) to CO2, and the δ(13)C signature in tissues of the algae. While S. polyschides and L. ochroleuca showed photosynthetic activity at pH 9.5 (around 1.0 µmol O2 m(-2) s(-1)), the activity was close to zero in both species of Phyllariopsis. The APS versus DIC was almost saturated for the DIC values of natural seawater (2 mM) in S. polyschides and L. ochroleuca, but the relationship was linear in P. brevipes and P. purpurascens. The four species showed total and CAext activities but the inhibition of the CAext originated the observed photosynthetic rates at pH 8.0 to be similar to the theoretical rates that could be supported by the spontaneous dehydration of HCO3(-). The isotopic (13)C signatures ranged from -17.40 ± 1.81 to -21.11 ± 1.73 ‰ in the four species. Additionally, the δ(13)C signature was also measured in the deep-water Laminaria rodriguezii growing at 60-80 m, showing even a more negative value of -26.49 ± 1.25 ‰. All these results suggest that the four kelps can use HCO3(-) as external carbon source for photosynthesis mainly by the action of external CAext, but

    Chimerism occurs when two genetically distinct conspecific individuals fuse together generating a single entity. Coalescence and chimerism in red seaweeds has been positively related to an increase in body size, and the consequent reduction in susceptibility to mortality factors, thus increasing survival, reproductive potential and tolerance to stress in contrast to genetically homogeneous organisms. In addition, they showed that a particular pattern of post-fusion growth maintains higher genetic diversity and chimerism in the holdfast but homogenous axes. In Chilean kelps (brown seaweeds), intraorganismal genetic heterogeneity (IGH) and holdfast coalescence has been described in previous research, but the extent of chimerism in wild populations and the patterns of distribution of the genetically heterogeneous thallus zone have scarcely been studied. Since kelps are under continuous harvesting, with enormous social, ecological and economic importance, natural chimerism can be considered a priceless in-situ reservoir of natural genetic resources and variability. In this study, we therefore examined the frequency of IGH and chimerism in three harvested populations of Lessonia spicata. We then evaluated whether chimeric wild-type holdfasts show higher genetic diversity than erect axes (stipe and lamina) and explored the impact of this on the traditional estimation of genetic diversity at the population level. We found a high frequency of IGH (60–100%) and chimerism (33.3–86.7%), varying according to the studied population. We evidenced that chimerism occurs mostly in holdfasts, exhibiting heterogeneous tissues, whereas stipes and lamina were more homogeneous, generating a vertical gradient of allele and genotype abundance as well as divergence, constituting the first time “within- plant” genetic patterns have been reported in kelps. This is very different from the chimeric patterns described in land plants and animals. Finally, we evidenced that IGH affected

    The current official quality control approaches meet the challenges from the complexity of herbal medicines.In fact,any herbal medicines containing numerous unknown components,its curative effect usually depends on the whole of herbal medicines,so it is impossible and unnecessary to qualitatively and quantitatively study every component.By investigating the limitations of current quality control approaches for herbal medicines and the difference and similarity in the chemical substantial style as well as quality control pattern of herbal medicines,a new quality control approach for Chinese herbal medicines should be explored and designed.The combination approach of chemical analysis with bioassay is promising to be developed and employed in order to ensure the safety and efficacy of Chinese herbal medicines.

    Chinese herbal property is the highly summarized concept of herbal nature and pharmaceutical effect, which reflect the characteristics of herbal actions on human body. These herbal actions, also interpreted as presenting the information about pharmaceutical effect contained in herbal property on the biological carrier, are defined as herbal property expressions. However, the biological expression of herbal property is believed to possess complex features for the involved complexity of Chinese medicine and organism. Firstly, there are multiple factors which could influence the expression results of herbal property such as the growth environment, harvest season and preparing methods of medicinal herbs, and physique and syndrome of body. Secondly, there are multiple biological approaches and biochemical indicators for the expression of the same property. This paper elaborated these complexities for further understanding of herbal property. The individuality of herbs and expression factors should be well analyzed in the related studies.

    In 1631, Richard Brathwaite penned a conduct manual for 'English Gentlewomen'. In Brathwaite's mind, the ideal English gentlewoman was not only chaste, modest and honourable but also an avid reader. In fact, Brathwaite specifically recommends English gentlewomen to first peruse herbals and then to deepen their medical knowledge via conference. Centred on the manuscript notebooks of two late seventeenth-century women, Margaret Boscawen (d. 1688) and Elizabeth Freke (1642-1714), this article explores women and 'medical reading' in early modern England. It first demonstrates that whilst both women consulted herbals by contemporary authors such as John Gerard and Nicholas Culpeper, their modes of reading could not be more different. Where Freke ruminated, digested and abstracted from Gerard's large tome, Boscawen made practical lists from Culpeper's The English Physitian. Secondly, the article shows that both supplemented their herbal reading with a range of other vernacular medical texts including printed medical recipe books, contemporary pharmacopoeia and surgical handbooks. Early modern English women's medical reading, I argue, was nuanced, sophisticated and diverse. Furthermore, I contend that well-informed readers like Boscawen and Freke made smart medical consumers and formidable negotiators in their medical encounters.

  15. Overfishing reduces resilience of kelp beds to climate-driven catastrophic phase shift.

    A key consideration in assessing impacts of climate change is the possibility of synergistic effects with other human-induced stressors. In the ocean realm, climate change and overfishing pose two of the greatest challenges to the structure and functioning of marine ecosystems. In eastern Tasmania, temperate coastal waters are warming at approximately four times the global ocean warming average, representing the fastest rate of warming in the Southern Hemisphere. This has driven range extension of the ecologically important long-spined sea urchin (Centrostephanus rodgersii), which has now commenced catastrophic overgrazing of productive Tasmanian kelp beds leading to loss of biodiversity and important rocky reef ecosystem services. Coincident with the overgrazing is heavy fishing of reef-based predators including the spiny lobster Jasus edwardsii. By conducting experiments inside and outside Marine Protected Areas we show that fishing, by removing large predatory lobsters, has reduced the resilience of kelp beds against the climate-driven threat of the sea urchin and thus increased risk of catastrophic shift to widespread sea urchin barrens. This shows that interactions between multiple human-induced stressors can exacerbate nonlinear responses of ecosystems to climate change and limit the adaptive capacity of these systems. Management actions focused on reducing the risk of catastrophic phase shift in ecosystems are particularly urgent in the face of ongoing warming and unprecedented levels of predator removal from the world's oceans.

  16. The paradox of inverted biomass pyramids in kelp forest fish communities.

    Theory predicts that bottom-heavy biomass pyramids or 'stacks' should predominate in real-world communities if trophic-level increases with body size (mean predator-to-prey mass ratio (PPMR) more than 1). However, recent research suggests that inverted biomass pyramids (IBPs) characterize relatively pristine reef fish communities. Here, we estimated the slope of a kelp forest fish community biomass spectrum from underwater visual surveys. The observed biomass spectrum slope is strongly positive, reflecting an IBP. This is incongruous with theory because this steep positive slope would only be expected if trophic position decreased with increasing body size (consumer-to-resource mass ratio, less than 1). We then used δ(15)N signatures of fish muscle tissue to quantify the relationship between trophic position and body size and instead detected strong evidence for the opposite, with PPMR ≈ 1650 (50% credible interval 280-12 000). The natural history of kelp forest reef fishes suggests that this paradox could arise from energetic subsidies in the form of movement of mobile consumers across habitats, and from seasonally pulsed production inputs at small body sizes. There were four to five times more biomass at large body sizes (1-2 kg) than would be expected in a closed steady-state community providing a measure of the magnitude of subsidies.

    2006-05-26

    Global-scale changes in anthropogenic nutrient input into marine ecosystems via terrestrial runoff, coupled with widespread predator removal via fishing, have created greater urgency for understanding the relative role of top-down versus bottom-up control of food web dynamics. Yet recent large-scale studies of community regulation in marine ecosystems have shown dramatically different results that leave this issue largely unresolved. We combined a multiyear, large-scale data set of species abundances for 46 species in kelp forests from the California Channel Islands with satellite-derived primary production and found that top-down control explains 7- to 10-fold more of the variance in abundance of bottom and mid-trophic levels than does bottom-up control. This top-down control was propagated via a variety of species-level direct and indirect responses to predator abundance. Management of top-down influences such as fishing may be more important in coastal marine ecosystems, particularly in kelp forest systems, than is commonly thought.

    Full Text Available Fatty acids in lipophilic fractions of the herbal composition as well as of the tincture obtained from it were detected and identified by the method of gas chromatography. The presence of this group of biologically active compounds supplements the biological value of the herbal medicine since fatty acids are responsible for the manifestation of antimicrobial properties along with flavonoids and volatile compounds. An antimicrobial activity of extraction agents was experimentally determined in regard to gram-positive and gram-negative microorganisms.

    Full Text Available Despite the great importance of grazing by herbivorous fishes in the marine environment, the knowledge of this phenomenon on seaweeds cultivationis very limited.Indeed, there is not available information on the effects of fish grazing in the farming of economically valuable kelps.During an investigation of the cultivation of commercial kelps Undaria pinnatifida and Saccharina latissima in North Western Atlantic coast of Spain (Galicia,it was found that grazing by fishes was sometimes responsible for removing of algal’s material from culture ropes.Fish grazing were generally rare and with a minor influence, usually its adverse effects are limited to a small decrease in the yield in some culture ropes,however,in some cases,it can also involve the lost of virtually the entire crop of culture rope.Most of herbivore grazing was associated to sparid fishes such as bogue(Boops boops,and salema(Sarpasalpa. Preferably, herbivorous fishes consumed blade of both cultured kelps when they were still young fronds(juvenile stage of algae. Indeed, blade of adult fronds was clearly less affected, and in S.latissima adults there was even not observed any fish grazing effects.Herein, different biotic and abiotic factors are discussed as possible causes of the influence of fish grazing on cultured kelps.

    The effect of diet supplemented with Phellinus linteus fed for 30 days was investigated in grouper Epinephelus bruneus challenged with Vibrio anguillarum, Vibrio harveyi, Vibrio alginolyticus, and Vibrio carchariae; infected and treated fish had a significantly higher percent weight gain and feed efficiency. In groups fed with enriched diet and challenged with V. anguillarum and V. harveyi the mortality rate declined with a consequent rise in survival rate than with other pathogens. On the other hand, in groups fed with P. linteus enriched diet and challenged with V. anguillarum, V. harveyi, and V. alginolyticus the cellular and humoral immune responses, such as the alternative complement activity (ACH(50)), serum lysozyme activity, phagocytic activity (PA), phagocytic index (PI) significantly higher than in the control group. The respiratory bursts (RB), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activities were found significantly enhanced when the groups fed with enriched diet against V. anguillarum and V. harveyi. The results reveal that kelp grouper fed for 30 days with P. linteus enriched diet had higher cellular and humoral immune response and disease protection from vibriosis than the group fed on basal diet with the protection linked to stimulation of immune system.

    Idiopathic sudden sensorineural hearing loss has great impact on quality of life. Many clinical trials using Chinese herbal medicine for idiopathic sudden sensorineural hearing loss have been conducted and reported beneficial results. However, there is no critical appraised evidence on efficacy and safety of Chinese herbal medicine for idiopathic sudden sensorineural hearing loss to inform clinical use. To assess the beneficial effect and safety of Chinese herbal medicine for idiopathic sudden sensorineural hearing loss. Systematic review of randomised clinical trials. Seven electronic databases and two trial registries were searched for all eligible trials from inception to January 2013. Two authors independently selected trials and extracted data. The Cochrane risk of bias tool was utilised to assess the methodological quality of the included trials. revman 5.2 software was applied for data analysis with effect estimate presented as risk ratio and mean difference with its 95% confidence interval. Forty-one randomised clinical trials involving 3560 participants were identified. Five kinds of Chinese herbal medicine were trialed. All trials compared conventional therapies of steroids, vasodilators, anticoagulants, nutritional supplements or hyperbaric oxygen with or without herbal medicine. No trial was identified that compared herbal medicine alone with placebo. No trial was identified that blinded the participants or the observers to their herbal medication. Only one trial adequately reported its method of randomisation. No trial reported the sample size calculated to show an effect. All trials had material other defects giving a high likelihood of bias. Because of the overall poor quality of all 41 trials, it was concluded that there was no level-one evidence to support the use of Chinese herbal medicine, alone or in addition to conventional therapies, to improve the hearing in adults with idiopathic sudden sensorineural hearing loss. Two trials reported adverse

    With over 50,000 dietary supplements available, resurgence in consumer interest over the past few decades has resulted in an explosion of use of these agents worldwide. Disillusionment with current medications and belief in "natural medicines" has resulted in a multibillion dollar industry. Active ingredients in a number of herbs are being tested for therapeutic potential, and some are efficacious, so herbal medicines cannot be dismissed. The prevalence of herbology is further encouraged by a relatively relaxed policy of the FDA regarding these compounds, which they consider foods. As herbal products are included in the "supplement" category, there is no existing protocol for standardization of these products. There are numerous examples of herbals that can adversely affect patient recovery and outcomes in anesthesia. The prudent anesthesia provider will make sure to obtain correct information as to accurate herbal usage of each patient and attempt to discontinue these products two to three weeks prior to the delivery of an anesthetic. Postoperative analgesia, bleeding, and level of sedation can be negatively impacted related to herbal products and herbal-drug interactions. Over 90 herbal products are associated with bleeding and this can be a specific problem intraoperatively or when considering placement of a regional anesthetic for postoperative pain management.

    Full Text Available Within contemporary Western herbal medicine, traditional knowledge and modern science are combined to provide a unique meeting of patient, practitioner and plant. In the Australian context, herbalists have based their practice on knowledge which originates from the traditions of Europe, and has more recently been influenced by traditional medicine from Asia. The combination of these diverse ways of knowing—traditional and modern, Eastern and Western—means herbal practitioners are influenced by ancient philosophy alongside phytochemistry and biomedical sciences. The challenge for herbal medicine today is that faced by all living (as opposed to ossified traditions: how is a practice forged which retains what is valuable from the past while establishing relevance to the 21st century? We illustrate these issues in the context of the conference theme of ‘food for thought’ and consider medicinal plants which are used for the improvement of cognition. We focus on the therapeutic use of common herbs from the Eastern and Western traditions and present the scientific research which shows their ability to facilitate cognitive function and the laying down of memory. We also tell their traditional stories which indicate that these actions have been recognised and utilised for centuries. We go on to demonstrate, via case studies, the clinical application of this knowledge and in particular the importance of ancient practice of synergistic prescribing which occurs when a number of herbs are prescribed together in a formula. Scientific understanding of the basis of this practice is being developed which further complements and validates traditional herbal wisdom.

    This study investigated the possibility of an alternative to chemical medication in the treatment of sexual dysfunction in healthy women. The efficacy of a unique herbal formulation of Muira puama and Ginkgo biloba (Herbal vX) was assessed in 202 healthy women complaining of low sex drive. Various aspects of their sex life were rated before and after 1 month of treatment. Responses to self-assessment questionnaires showed significantly higher average total scores from baseline in 65% of the sample after taking the supplement. Statistically significant improvements occurred in frequency of sexual desires, sexual intercourse, and sexual fantasies, as well as in satisfaction with sex life, intensity of sexual desires, excitement of fantasies, ability to reach orgasm, and intensity of orgasm.

    Two analogues of sildenafil were detected in herbal dietary supplements marketed as aphrodisiacs. Both compounds were identified as thioketone analogues of sildenafil in which the carbonyl group in the pyrimidine ring of sildenafil was substituted with a thiocarbonyl group. The first compound was identified as thiosildenafil, a compound that has recently been reported as an adulterant in health supplements. The structure of the second compound was established using LC-MS, UV spectroscopy, ESI-MS(n), NMR and a hydrolytic process. A detailed study of the hydrolysis products of sildenafil, thiosildenafil, and the second unknown compound proved that the second compound, named thiomethisosildenafil, had a structure analogous to sildenafil in which the N-methylpiperazine moiety had been replaced with 2,6-dimethylpiperazine and the oxygen atom of the carbonyl group in the heterocyclic ring had been replaced with a sulfur atom. Under the hydrolytic reaction conditions employed in this study, thioketones hydrolyze to ketones (e.g., thiosildenafil-->sildenafil), making this a valuable technique for the structure elucidation of thiosildenafil analogues. Ten herbal dietary supplements, each as a capsule dosage form, were found to contain 8-151 mg of thiomethisosildenafil per capsule, and one herbal dietary supplement was found to contain 35 mg of thiosildenafil per capsule.

    Dispersal on floating seaweeds depends on availability, viability, and trajectories of the rafts. In the southern hemisphere, the bull kelp Durvillaea antarctica is one of the most common floating seaweeds, but phylogeographic studies had shown low connectivity between populations from continental Chile, which could be due to limitations in local supply and dispersal of floating kelps. To test this hypothesis, the spatiotemporal dynamics of kelp strandings were examined in four biogeographic districts along the Chilean coast (28°-42°S). We determined the biomass and demography of stranded individuals on 33 beaches for three subsequent years (2013, 2014, 2015) to examine whether rafting is restricted to certain districts and seasons (winter or summer). Stranded kelps were found on all beaches. Most kelps had only one stipe (one individual), although we also frequently found coalesced holdfasts with mature males and females, which would facilitate successful rafting dispersal, gamete release, and reproduction upon arrival. High biomasses of stranded kelps occurred in the northern-central (30°S-33°S) and southernmost districts (37°S-42°S), and lower biomasses in the northernmost (28°S-30°S) and southern-central districts (33°S-37°S). The highest percentages and sizes of epibionts (Lepas spp.), indicative of prolonged floating periods, were found on stranded kelps in the northernmost and southernmost districts. Based on these results, we conclude that rafting dispersal can vary regionally, being more common in the northernmost and southernmost districts, depending on intrinsic (seaweed biology) and extrinsic factors (shore morphology and oceanography) that affect local supply of kelps and regional hydrodynamics.

    The Italian herbal products market is the most prosperous in Europe. The proof is represented by the use of these products in several marketing categories, ranging from medicine to nutrition and cosmetics. Market and legislation in Italy are at the same time cause and consequence of this peculiar situation. In fact, the legislation on botanical food supplements in Italy is very permissive and at the same time the market shows an overall satisfaction of users and strong feedback in terms of consumption, which brings a widening use of medicinal plants, formerly the prerogative of pharmaceuticals, to other fields such as nutrition. This review summarizes the market and normative panorama of herbal products in Italy, highlighting the blurred boundaries of health indications, marketing authorizations and quality controls between herbal medicines and non pharmaceutical products, such as food supplements, cosmetics and other herbal-based "parapharmaceuticals".

    The growth of herbal markets has increased substantially in South Korea, but the worldwide market share remains small despite significant governmental efforts. This study aimed to characterize manufacturing employment and identify employees' general perceptions of market expansion. A survey study covering 567 companies was conducted using face-to-face interviews in 2012. Data were analyzed using comparisons among three manufacturing groups (i.e., the herbal dietary supplement manufacturing group, the herbal medicine manufacturing group, and the personal care product manufacturing group) or among the manufacturers themselves. We found that the majority of the manufacturing employee respondents were regular permanent and production workers. The domestic distributors were primarily chain stores/direct outlets or retailers/wholesalers, and the dominant product was red ginseng (hongsam). Although the responding companies exhibited a variety of perspectives, "advertisement/public relations" was cited as the most important factor in the development of the herbal industry. In contrast, "low manpower/seeking business partners" were the most crucial limiting and challenging factors for market globalization. Our results can be used to design a proper national plan by reducing the gaps in perspective between herbal product producers and policy makers.

    The effect of diets containing sodium alginate at 0, 0.5, 1.0, and 2.0 g kg⁻¹ following challenge with Streptococcus iniae in kelp grouper Epinephelus bruneus were assessed with reference to survival rate and innate immune parameters such as alternative complement, lysozyme, natural haemagglutination, respiratory burst, superoxide dismutase, and phagocytic activities on week 1, 2, and 4. Fish fed with sodium alginate containing diet at 1.0 and 2.0 g kg⁻¹ after being challenged with S. iniae had higher survival rates of 75% and 60%, respectively than those fed with control diet (0 g kg⁻¹). With any enriched diet the percentage of macrophages significantly decreased from week 1-4, while the percentage of neutrophils and lymphocytes significantly increased. The alternate complement activity, natural haemagglutination, and phagocytic activities of infected fish fed with sodium alginate containing diet at 1.0 g kg⁻¹ on week 2 and 1.0 and 2.0 g kg⁻¹ diets on week 4 were significantly higher when compared to the control. The lysozyme, respiratory bursts, and superoxide dismutase activities of fish fed with enriched diets at 1.0 and 2.0 g kg⁻¹ were significantly increased on week 2 and 4. We therefore recommend that at 1.0 or 2.0 g kg⁻¹ dietary administration of sodium alginate can enhance innate immunity and disease resistance in kelp grouper against S. iniae.

    The intensive commercial exploitation of California sheephead (Semicossyphus pulcher) has become a complex, multimillion-dollar industry. The fishery is of concern because of high harvest levels and potential indirect impacts of sheephead removals on the structure and function of kelp forest ecosystems. California sheephead are protogynous hermaphrodites that, as predators of sea urchins and other invertebrates, are critical components of kelp forest ecosystems in the northeast Pacific. Overfishing can trigger trophic cascades and widespread ecological dysfunction when other urchin predators are also lost from the system. Little is known about the ecology and abundance of sheephead before commercial exploitation. Lack of a historical perspective creates a gap for evaluating fisheries management measures and marine reserves that seek to rebuild sheephead populations to historical baseline conditions. We use population abundance and size structure data from the zooarchaeological record, in concert with isotopic data, to evaluate the long-term health and viability of sheephead fisheries in southern California. Our results indicate that the importance of sheephead to the diet of native Chumash people varied spatially across the Channel Islands, reflecting modern biogeographic patterns. Comparing ancient (~10,000 calibrated years before the present to 1825 CE) and modern samples, we observed variability and significant declines in the relative abundance of sheephead, reductions in size frequency distributions, and shifts in the dietary niche between ancient and modern collections. These results highlight how size-selective fishing can alter the ecological role of key predators and how zooarchaeological data can inform fisheries management by establishing historical baselines that aid future conservation.

  2. Herbivore-Alga Interaction Strength Influences Spatial Heterogeneity in a Kelp-Dominated Intertidal Community.

    Full Text Available There is a general consensus that marine herbivores can affect algal species composition and abundance, but little empirical work exists on the role of herbivores as modifiers of the spatial structure of resource assemblages. Here, we test the consumption/bulldozing effects of the molluscan grazer Enoplochiton niger and its influence on the spatial structure of a low intertidal community dominated by the bull kelp Durvillaea antarctica and the kelp Lessonia spicata. Through field experiments conducted at a rocky intertidal shore in north-central Chile (~30°-32°S, the edge of the grazer and algae geographic distributions, we estimated the strength and variability of consumptive effects of the grazer on different functional group of algae. We also used data from abundance field surveys to evaluate spatial co-occurrence patterns of the study species. Exclusion-enclosure experiments showed that E. niger maintained primary space available by preventing algal colonization, even of large brown algae species. The grazing activity of E. niger also reduced spatial heterogeneity of the ephemeral algal species, increasing bare space availability and variability through time in similar ways to those observed for the collective effect with other grazers. Overall, our result suggests that E. niger can be considered an important modifier of the spatial structure of the large brown algae-dominated community. Effects of E. niger on resource variability seem to be directly related to its foraging patterns, large body size, and population densities, which are all relevant factors for management and conservation of the large brown algae community. Our study thus highlights the importance of considering functional roles and identity of generalist consumers on spatial structure of the entire landscape.

  4. The biogeography of kelps (Laminariales, Phaeophyceae): a global analysis with new insights from recent advances in molecular phylogenetics

    Bolton, John J.

    2010-12-01

    Despite their ecological and economic importance, no summary of kelp global biogeography has been produced for almost two decades. The circumscription of the order Laminariales and familial and generic relationships in the group have changed considerably recently, in the light of molecular data. A global summary and geographical analysis of kelp species and their distributions (112 species in 33 genera) is presented. These data are analysed and discussed from the perspective of the new consensus of relationships within the group, and likely evolutionary events. The putative ancestors of the kelps occur and are overwhelmingly most diverse, in the cooler waters of northern Japan. The biogeographical evidence suggests three main lines of subsequent evolution: (a) a diversification producing the four ‘derived’ families Alariaceae, Costariceae, Laminariaceae, and Lessoniaceae and most extant genera in the temperate northern Pacific, probably during the Miocene. (b) The evolution of an Arctic flora which invaded the North Atlantic following the opening of the Bering Strait ca. 5.5 Ma. (c) At least four separate crossings, by different genera, of tropical regions from Northern to Southern Hemisphere (and one in the opposite direction). The recorded impacts of man on these distributions have thus far been minimal, with the notable exceptions of Undaria pinnatifida and species of Saccharina (grown in aquaculture systems for human food). Most genera are monospecific, with many confined to either the western or eastern temperate North Pacific, whereas the distribution of the most species-rich genera ( Alaria, Laminaria, Saccharina) includes the Arctic, and they are widespread in the North Atlantic. This rapid species-level evolution is hypothesised to have been promoted by the relatively recent invasion of the Atlantic by these taxa. The crossing of the tropics has occurred in warm-temperate species some of which occur and are sometimes abundant, in deeper water in today

    Rich Brazilian biodiversity is accompanied by a long acceptance of medicinal plants and traditional knowledge by the Brazilian population. To improve the regulatory framework for herbal medicines in Brazil, ANVISA recently revised its legislations. The aim of this study is to discuss the new Brazilian standards for herbal medicines regulation. The national and international legislation on herbal medicines was revised to prepare new Brazilian standards. This new legislation is discussed. This new proposed regulation separates herbal into two categories: herbal medicines (HM) and traditional herbal product (THP). The safety and efficacy of HM must be proven by clinical data. ANVISA recognizes some plants as safe and effective; therefore, the registration of these species can be simplified. ANVISA also recognizes the monographs of the European community as simplified registrations. THP can prove their safety and effectiveness by tradition of use or following a simplified registration. Brazil has been altering their legal standards for herbal medicines, based on harmonization with internationally practiced requirements and the characteristics of the Brazilian market, facilitating the safe access and rational use of medicinal plants and herbal products to Brazilian population.

    The uses of herbal products are not regulated in Nigeria and in many low-income countries and are freely available to everyone. The safety of these herbal medicines is poorly understood. This study characterizes the content of cadmium, copper, iron, nickel, selenium, zinc, lead and mercury in a random sample of Nigerian traditional products. Ready-to-use herbal products were purchased from the open market and digested using HNO{sub 3}.The heavy metal content of the digested filtrate was determined by atomic absorption spectrometry Uni-cam Model 929. The result showed that 100% of the samples contained elevated amounts of heavy metals. These data alert us to the possibility of heavy metal toxicity from herbal products in Nigeria. The public health hazards from ingestion of herbal medicines should be identified and disclosed by in-depth risk assessment studies.

    This study introduces an innovative method for biomonitoring using giant kelp (Macrocystis pyrifera) sieve tube sap (STS) metal concentrations as an indication of pollution influence. STS was sampled from fronds collected from 10 southern California locations, including two reference sites on Santa Catalina Island. Using ICP-MS methodology, STS concentrations of 17 different metals were measured (n=495). Several metals associated with pollution showed the highest STS concentrations and most seasonal variation from populations inside the Port of Los Angeles/Long Beach. Lowest concentrations were measured at less-urbanized areas: Santa Catalina Island and Malibu. Some metals showed a spatial gradient in STS metal concentration with increasing distance from point sources (i.e. Los Angeles River). Cluster analyses indicate that polluted seawater may affect kelp uptake of metals essential for cellular function. Results show that this method can be useful in describing bioavailable metal pollution with implications for accumulation within an important ecosystem.

    Directory of Open Access Journals (Sweden)

    Nathan L. Stewart

    2012-01-01

    Full Text Available Macroalgal and urchin barren communities are alternately stable and persist in the Aleutians due to sea otter presence and absence. In the early 1990s a rapid otter population decline released urchins from predation and caused a shift to the urchin-dominated state. Despite increases in urchin abundance, otter numbers continued to decline. Although debated, prey quality changes have been implicated in current otter population status. This study examined otter prey abundance, size, biomass, and potential energy density in remnant kelp forest and urchin-dominated communities to determine if alternate stable states affect prey quality. Findings suggest that although urchin barrens provide more abundant urchin prey, individual urchins are smaller and provide lower biomass and potential energy density compared to kelp forests. Shifts to urchin barrens do affect prey quality but changes are likely compensated by increased prey densities and are insufficient in explaining current otter population status in the Aleutians.

    The stipes of older Laminaria hyperborea individuals are heavily covered by epiphytic assemblages that are dominated by macroalgae, and we hypothesized that the production of these algae may contribute significantly to total primary production of the kelp forest ecosystem. The epiphytic assemblages...... of the epiphytic assemblages indicated that they were acclimated to shade, and the poor sub-canopy light conditions were nevertheless sufficient to ensure positive net photosynthesis for at least 2 to 3 h daily throughout the year. Photosynthetic efficiency at low light and dark respiration varied seasonally...... through spring as surface irradiance increased. Annual net productivity was relatively low, ranging from 42 to 96 g DW m-2 seafloor depending on site. We conclude that the net productivity of these macroalgal epiphytes is insignificant relative to that of kelp itself, and that the large observed biomass...

    Jeukendrup, A E; Randell, R

    2011-10-01

    The term 'fat burner' is used to describe nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure, impair fat absorption, increase weight loss, increase fat oxidation during exercise, or somehow cause long-term adaptations that promote fat metabolism. Often, these supplements contain a number of ingredients, each with its own proposed mechanism of action and it is often claimed that the combination of these substances will have additive effects. The list of supplements that are claimed to increase or improve fat metabolism is long; the most popular supplements include caffeine, carnitine, green tea, conjugated linoleic acid, forskolin, chromium, kelp and fucoxanthin. In this review the evidence for some of these supplements is briefly summarized. Based on the available literature, caffeine and green tea have data to back up its fat metabolism-enhancing properties. For many other supplements, although some show some promise, evidence is lacking. The list of supplements is industry-driven and is likely to grow at a rate that is not matched by a similar increase in scientific underpinning.

  1. Weight Loss Nutritional Supplements

    Science.gov (United States)

    Eckerson, Joan M.

    Obesity has reached what may be considered epidemic proportions in the United States, not only for adults but for children. Because of the medical implications and health care costs associated with obesity, as well as the negative social and psychological impacts, many individuals turn to nonprescription nutritional weight loss supplements hoping for a quick fix, and the weight loss industry has responded by offering a variety of products that generates billions of dollars each year in sales. Most nutritional weight loss supplements are purported to work by increasing energy expenditure, modulating carbohydrate or fat metabolism, increasing satiety, inducing diuresis, or blocking fat absorption. To review the literally hundreds of nutritional weight loss supplements available on the market today is well beyond the scope of this chapter. Therefore, several of the most commonly used supplements were selected for critical review, and practical recommendations are provided based on the findings of well controlled, randomized clinical trials that examined their efficacy. In most cases, the nutritional supplements reviewed either elicited no meaningful effect or resulted in changes in body weight and composition that are similar to what occurs through a restricted diet and exercise program. Although there is some evidence to suggest that herbal forms of ephedrine, such as ma huang, combined with caffeine or caffeine and aspirin (i.e., ECA stack) is effective for inducing moderate weight loss in overweight adults, because of the recent ban on ephedra manufacturers must now use ephedra-free ingredients, such as bitter orange, which do not appear to be as effective. The dietary fiber, glucomannan, also appears to hold some promise as a possible treatment for weight loss, but other related forms of dietary fiber, including guar gum and psyllium, are ineffective.

    Crustose coralline algae were the prevalent cover among sessile organisms that paved or grew near the substratum, and also the most commonly overgrown species in a giant kelp Macrocystis pyrifera (L.) C.A. Agardh forest located off San Nicolas Island, California. Giant kelp was the largest and most conspicuous species that overgrew large patches of the substrata; overgrowth among turf organisms also appeared common. To determine the effects of giant kelp holdfasts on crustose coralline algae and other turf organisms,'artificial holdfasts' were placed on 0.125-m2 plots for 5, 8 and 12 months. In these treatments, 50?57% of the crustose coralline algae survived. Because these algae also recruited while covered, the total cover (survivorship plus recruitment) differed by only 7?26% from that sampled at the start of the study. The decline of these algae in control plots was similar to that in the treatment plots mostly because of overgrowth by sessile invertebrates. Bryozoans increased markedly on the control plots, whereas 0?12% survived in the treatment plots. Bryozoans and sponges also recruited under the artificial holdfasts. Some arborescent turf algae survived in the 5- and 8-month treatments; articulated coralline algae survived better than did foliose algae. High survival recruitment of crustose coralline algae while overgrown contributed to their prevalence in benthic communities.

    Herbal formulations being widely accepted therapeutic agents as antidiabetics, antiarthritics, hepatoprotectives, cough remedies, memory enhancers, and adaptogens. The commonest myth regarding herbal medicines is that these medicines are completely safe, and can therefore be safely consumed by the patient on his/her own, without a physician's prescription. This belief has led to large-scale self-medication by people all over the world, often leading to disappointing end-results, side-effects, or unwanted after-effects. There is an increasing awareness at several levels of the need to develop pharmacovigilance practices for herbal medicines. The current model of pharmacovigilance and its associated tools have been developed in relation to synthetic drugs, and applying these methods to monitoring the safety of herbal medicines presents unique challenges in addition to those described for conventional medicines. Several problems relate to the ways in which herbal medicines are named, perceived, sourced, and utilized. This may be because of differences in the use of nonorthodox drugs (e.g., herbal remedies) which may pose special toxicological problems, when used alone or in combination with other drugs. The purpose of pharmacovigilance is to detect, assess, and understand, and to prevent the adverse effects or any other possible drug-related problems, related to herbal, traditional, and complementary medicines.

    Full Text Available , (Received 21 Jun, 2008 ; Accepted 12 Nov, 2008 AbstractAccording to the statistics provided by the World Health Organization (WHO, about 80% of the world population nowadays uses herbal drugs for treatment of diseases. Natural products obtained from medicinal plants, serve as a great source for drug production and are the main basis of new drug compounds. Unicellular organisms (Protozoa are the cause of deaths and spread of diseases in various societies, especially in developing countries. There are anti-malaria herbal dugs produced from various medicinal plants, some of which are used for treatment of the disease and some under study. The first anti-malaria drug was quinine, produced from bark of the Cinchona tree. Recently, the drug artemisinin has been introduced by Chinese scientists for the treatment of malaria and is currently used extensively. Coetaneous leishmaniosis (salak is one of the endemic diseases in most parts of Iran. Common drugs used against leishmaniosis (such as glucantim, have severe side-effects and in 10 to 25% of cases, there is a recurrence of the disease. Emetine is one of the drugs obtained from a root of the plant Ipecac, which is used for treatment of the disease sub-cutaneously. Giardiasis is an acute protozoan infection usually with no clinical symptoms, however, may appear as acute or chronic diarrhea. According to the announcement of WHO, more than 2/3 of the world’s population is infected with intestinal parasites and the prevalence of giardia is higher than other intestinal parasites. Herbal drugs, such as wild garlic, eucalyptus and thyme, are some of the major plants which can annihilate the giarda cysts. Annually, 75000 to 100000 people die of amebiasis (dysentery worldwide. Due to the motility of the organism, it causes sever pathological changes and sometimes colon ulcers, and if entered into the blood stream, it may appear as liver or brain abscess.

    Full Text Available The prevalence of obesity is increasing at an alarming rate in recent years. Many drugs for weight managing are available in the market; however their adverse effects and hazards have not been thoroughly evaluated, therefore herbal medicines are being proposed as an efficient, inexpensive and safe alternative. This review will address the current advances in using traditional herbal plants in obese and overweight humans and animals. Searching data bases were PubMed, Scopus, Google Scholar and Science direct, reported between 1990 and 2014. Articles were screened and selected by two researchers. Based on the available literature, abstract/full randomized clinical trials (RCTs, evidence studies, reviews, systematic reviews and books were surveyed. Studies with LI85008F, Itrifal Saghir, Hunteria umbellate, Morus alba, Melissa officinalis, and Artemisia capillarie, pomegranate leaf (PLE, NT (rhubarb, ginger, astragulus, red sage, and turmeric combined with gallic acid (GA, ephedrine, caffeine, salicin, Adlay seed crude extract (ACE, Bufo-tsusho-san (BF and Stimulant-free supplement (glucomannan, chitosan, fenugreek, Gymnema sylvestre, and vitamin C show significant decreases in body weight.

    Directory of Open Access Journals (Sweden)

    Young-Beob Yu

    Full Text Available BACKGROUND: Proving the efficacy and corresponding mode of action of herbal supplements is a difficult challenge for evidence-based herbal therapy. A major hurdle is the complexity of herbal preparations, many of which combine multiple herbs, particularly when the combination is assumed to be vitally important to the effectiveness of the herbal therapy. This issue may be addressed through the use of contemporary methodology and validated animal models. METHODS AND PRINCIPAL FINDINGS: In this study, two commonly used traditional herbal formulas, Shi Quan Da Bu Tang (SQDB and Huo Luo Xiao Ling Dan (HLXL were evaluated using a survival assay and oxidative stress biomarkers in a well-established C. elegans model of aging. HLXL is an eleven herb formula modified from a top-selling traditional herbal formula for the treatment of arthritic joint pain. SQDB consists of ten herbs often used for fatigue and energy, particularly in the aged. We demonstrate here that SQDB significantly extend life span in a C. elegans model of aging. Among all individual herbs tested, two herbs Cinnamomum cassia bark (Chinese pharmaceutical name: Cinnamomi Cortex, CIN and Panax ginseng root (Chinese pharmaceutical name: Ginseng Radix, GS significantly extended life span in C. elegans. CIN in both SQDB and HLXL formula extended life span via modulation of multiple longevity assurance genes, including genes involved in insulin signaling and stress response pathways. All the life-span-extending herbs (SQDB, CIN and GS also attenuated levels of H2O2 and enhanced small heat shock protein expression. Furthermore, the life span-extending herbs significantly delayed human amyloid beta (Abeta-induced toxicity in transgenic C. elegans expressing human Abeta. CONCLUSION/SIGNIFICANCE: These results validate an invertebrate model for rapid, systematic evaluation of commonly used Chinese herbal formulations and may provide insight for designing future evidence-based herbal therapy(s.

    Nonalcoholic fatty liver disease (NAFLD), which is characterized by excessive fat accumulation in the liver of patients who consume little or no alcohol, becomes increasingly common with rapid economic development. Long-term excess fat accumulation leads to NAFLD and represents a global health problem with no effective therapeutic approach. NAFLD is considered to be a series of complex, multifaceted pathological processes involving oxidative stress, inflammation, apoptosis, and metabolism. Over the past decades, herbal medicines have garnered growing attention as potential therapeutic agents to prevent and treat NAFLD, due to their high efficacy and low risk of side effects. In this review, we evaluate the use of herbal medicines (including traditional Chinese herbal formulas, crude extracts from medicinal plants, and pure natural products) to treat NAFLD. These herbal medicines are natural resources that can inform innovative drug research and the development of treatments for NAFLD in the future.

    We report an extensive intra-operative bleed which may have occurred as a result of the patient taking a herbal medicine. The patient underwent orthognathic surgery as a part of his orthodontic treatment, and lost approximately 3.5 litres of blood during the procedure. Preoperative blood tests were normal; the patient took no prescription medications and an appendectomy had been performed without incident. To aid healing, however, the patient had taken arnica the day before his operation. A concise literature review is presented which outlines the causes of surgical bleeding and discusses some of the bleeding concerns that herbal medicine use may raise for clinicians. Herbal medicines may contribute to unexplained surgical bleeding in the absence of other causative factors; it would therefore be useful to include an enquiry about the taking of herbal remedies at the history-taking stage for dental and maxillofacial surgical procedures.

    The European Directive 2004/24/EC introducing a simplified registration procedure for traditional herbal medicinal products, plays an important role in harmonising the current legislation framework for all herbal medicinal products in the European Union (EU). Although substantial achievements have been made under the new scheme, only a limited number of herbal medicinal products from non-European traditions commonly used in Europe have been registered. Therefore, identification of the obstacles, and determination of appropriate means to overcome the major challenges in the registration of non-European traditional herbal medicinal products are of critical importance for the EU herbal medicinal product market. The primary aims of this study were to understand the key issues and obstacles to registration of non-European traditional herbal medicinal products within the EU. The findings may identify the need for more attention on the Community herbal monographs elaborated by the Herbal Medicinal Products Committee (HMPC), as well as further evidence based scientific research on non-European herbal substances/preparations by the scientific community. A systematic evaluation of the herbal substances and preparations included in Community herbal monographs and public statements has been carried out. The focus was herbal substances and preparations derived from non-European traditions. Of the 109 adopted Community herbal monographs, 10 are herbal substances used in Chinese traditional medicine. Where the HMPC issued a public statement because it was unable to elaborate a monograph more than half-involved herbal substances/preparations from non-European traditions. The main reasons herbal substances/preparations from non-European traditions were not accepted for inclusion in the Community herbal monographs have been identified as due to unfulfilled requirements of Directive 2004/24/EC. The most common reasons were the lack of evidence to demonstrate a 15-year minimum

    2012-03-01

    Full Text Available One challenge in current Arctic ecological research is to understand and predict how wildlife may respond to increased frequencies of “extreme” weather events. Heavy rain-on-snow (ROS is one such extreme phenomenon associated with winter warming that is not well studied but has potentially profound ecosystem effects through changes in snow-pack properties and ice formation. Here, we document how ice-locked pastures following substantial amounts of ROS forced coastal Svalbard reindeer (Rangifer tarandus platyrhynchus to use marine habitat in late winter 2010. A thick coat of ground ice covered 98% of the lowland ranges, almost completely blocking access to terrestrial forage. Accordingly, a population census revealed that 13% of the total population (n=26 of 206 individuals and 21% of one sub-population were feeding on washed-up kelp and seaweed on the sea-ice foot. Calves were overrepresented among the individuals that applied this foraging strategy, which probably represents a last attempt to avoid starvation under particularly severe foraging conditions. The study adds to the impression that extreme weather events such as heavy ROS and associated icing can trigger large changes in the realized foraging niche of Arctic herbivores.

    To explore the effects of kelp waste extracts (KWE) on the growth and development of Brassia chinensis L., germination and greenhouse experiments were carried out under different concentrations of KWE. The results showed that a higher germination percentage (95%), associated with high germination index (8.70), germination energy (71.67%) and seedling vigor index (734.67), was obtained under a lower KWE concentration (2%) compared with the control. The radicle length (4.97 cm), fresh weight (0.32 g/10 seedlings) and dry weight (0.015 g/10 seedlings) were significantly increased in the treatment of 2% KWE. KWE also could enhance the root growth, the maximum leaf length × width and the fresh weight of plants, the optimal value of which increased by 8.37 cm, 58.14 cm2 and 7.76 g under the treatment of 10% KWE compared with the control respectively. Meanwhile, the contents of vitamin C and soluble sugars in pakchoi leaf were improved by 19.6 mg/100 g and 1.44 mg/g compared with the control, and the nitrate content was decreased by 212.27 mg/kg. Briefly, KWE could markedly stimulate the pakchoi seeds germination at a lower concentration (2%) and enhance the plant growth and quality at a higher concentration (10%).

    The cultivation of seaweed as a feedstock for third generation biofuels is gathering interest in Europe, however, many questions remain unanswered in practise, notably regarding scales of operation, energy returns on investment (EROI) and greenhouse gas (GHG) emissions, all of which are crucial to determine commercial viability. This study performed an energy and GHG emissions analysis, using EROI and GHG savings potential respectively, as indicators of commercial viability for two systems: the Swedish Seafarm project's seaweed cultivation (0.5ha), biogas and fertilizer biorefinery, and an estimation of the same system scaled up and adjusted to a cultivation of 10ha. Based on a conservative estimate of biogas yield, neither the 0.5ha case nor the up-scaled 10ha estimates met the (commercial viability) target EROI of 3, nor the European Union Renewable Energy Directive GHG savings target of 60% for biofuels, however the potential for commercial viability was substantially improved by scaling up operations: GHG emissions and energy demand, per unit of biogas, was almost halved by scaling operations up by a factor of twenty, thereby approaching the EROI and GHG savings targets set, under beneficial biogas production conditions. Further analysis identified processes whose optimisations would have a large impact on energy use and emissions (such as anaerobic digestion) as well as others embodying potential for further economies of scale (such as harvesting), both of which would be of interest for future developments of kelp to biogas and fertilizer biorefineries.

    This is a cross-sectional, descriptive study among Malay women admitted in the antenatal and postnatal ward to determine the prevalence and use of herbal medicines during pregnancy and elemental analysis in the most popular herbs. A total of 460 women were surveyed. Herbal medicine use during pregnancy was 34.3%, while 73% utilized herbal medicines during labor, because of a belief that it may shorten and ease labor. The most commonly used herbal medicines in pregnancy were Anastatica hierochuntica L. (60.1%) followed by coconut oil (35.4%). The majority of women (89.2%) used only one type of herbal medicines and took one capsule/glass (38%) per day. Herbal medicines use by pregnant women is largely unsupervised (81%), with most women getting information from their parents (60.7%) and buying the products directly from traditional midwives (32.2%) and 77% agreed upon its efficacy and safety. From the 460 respondents, 89.8% women were in the low end of the herbs knowledge. There was a significant difference found between knowledge score and income (P < 0.05). Microdiffraction analysis revealed significant presence of carbon, oxygen, silica, calcium, magnesium, aluminium, potassium, zinc, and iron that were found in Anastatica hierochuntica L. and proved to have good benefits for pregnancy.

    The prevalence and comorbidity of psychiatric disorders such as depression, anxiety and insomnia are very common. These well-known forms of psychiatric disorders have been affecting many people from all around the world. Herb alone, as well as herbal formula, is commonly prescribed for the therapies of mental illnesses. Since various adverse events of western medication exist, the number of people who use herbs to benefit their health is increasing. Over the past decades, the exploration in the area of herbal psychopharmacology has received much attention. Literatures showed a variety of herbal mechanisms of action used for the therapy of depression, anxiety and insomnia, involving re-uptake of monoamines, affecting neuroreceptor binding and channel transporter activity, modulating neuronal communication or hypothalamic-pituitary adrenal axis (HPA) etc. Nonetheless, a systematic review on herbal pharmacology in depression, anxiety and insomnia is still lacking. This review has been performed to further identify modes of action of different herbal medicine, and thus provides useful information for the application of herbal medicine. PMID:26412068

    2005-12-01

    Complementary and alternative medicine (CAM) is now a significant practice issue for those delivering cancer care with a range of CAM being utilized by a significant number of patients with cancer. While various studies have explored the prevalence of CAM use among cancer patients, little is currently known about naturopathy/herbalism use by patients with cancer in Australia. This paper reports the prevalence of naturopath/herbalist consultations among mid-aged Australian women with cancer. The research was conducted as part of the Australian Longitudinal Study on Women's Health, with the data for this analysis coming from the third survey of 11,202 women aged 50-55, conducted in 2001. For all cancers combined, 15.7% of women with cancer were found to consult a naturopath/herbalist. Mid-aged women with cancer were found to be more likely to consult a naturopath/herbalist than mid-aged women without cancer. Naturopathy/herbalism consultations appear to be utilized by the women with cancer alongside and as a supplement to conventional health services. Given the prevalence of consultations with herbal therapists/naturopaths among mid-aged women with cancer in Australia, it is important that physicians and others involved in cancer patient care and management are informed and educated about naturopathy/herbalism and its use among their patients.

    The aim of this study was to find out the surface roughness of composite resin veneer after brushing. In this study, 24 specimens of composite resin veneer are divided into three subgroups: brushed without toothpaste, brushed with non-herbal toothpaste, and brushed with herbal toothpaste. Brushing was performed for one set of 5,000 strokes and continued for a second set of 5,000 strokes. Roughness of composite resin veneer was determined using a Surface Roughness Tester. The results were statistically analyzed using Kruskal-Wallis nonparametric test and Post Hoc Mann-Whitney. The results indicate that the highest difference among the Ra values occurred within the subgroup that was brushed with the herbal toothpaste. In conclusion, the herbal toothpaste produced a rougher surface on composite resin veneer compared to non-herbal toothpaste.

    Full Text Available Distribution and abundance of the amphipod Caprella septentrionalis in relation to environmental conditions and habitat preferences were investigated in a kelp forest in Hornsund, Spitsbergen. Three sampling sites differed in hydrodynamics, organic and inorganic suspension concentration, and sedimentation rates. None of these abiotic factors or species of a macroalgal host appeared to have a significant influence on C. septentrionalis abundance and size range. An apparent preference towards the blade parts of the algal thalli was observed. These results support the idea of C. septentrionalis as a generalist Arctic–boreal species that takes advantage of the protective nature of kelp forests.

    Size-structured predator-prey interactions can be altered by the history of exploitation, if that exploitation is itself size-selective. For example, selective harvesting of larger sized predators can release prey populations in cases where only large individuals are capable of consuming a particular prey species. In this study, we examined how the history of exploitation and recovery (inside marine reserves and due to fisheries management) of California sheephead (Semicossyphus pulcher) has affected size-structured interactions with sea urchin prey in southern California. We show that fishing changes size structure by reducing sizes and alters life histories of sheephead, while management measures that lessen or remove fishing impacts (e.g. marine reserves, effort restrictions) reverse these effects and result in increases in density, size and biomass. We show that predation on sea urchins is size-dependent, such that the diet of larger sheephead is composed of more and larger sized urchins than the diet of smaller fish. These results have implications for kelp forest resilience, because urchins can overgraze kelp in the absence of top-down control. From surveys in a network of marine reserves, we report negative relationships between the abundance of sheephead and urchins and the abundance of urchins and fleshy macroalgae (including giant kelp), indicating the potential for cascading indirect positive effects of top predators on the abundance of primary producers. Management measures such as increased minimum size limits and marine reserves may serve to restore historical trophic roles of key predators and thereby enhance the resilience of marine ecosystems.

  4. ASPECTS OF THE BREEDING BIOLOGY OF KELP GULL LARUS DOMINICANUS (CHARADRIIFORMES, LARIDAE IN THREE ISLANDS NORTH OFF PERU

    Figueroa, Judith

    2011-01-01

    Full Text Available Between November and December 2004, an evaluation was done of some aspects of breeding biology of the kelp gull Larus dominicanus (Lichtenstein, 1823 in Lobos de Afuera, Lobos de Tierra and Foca islands, located off northern Peru. An association was found between the colonies of this species with the South American sea lion Otariaflavescens (Shaw, 1800 in Lobos de Afuera and Foca, with the blue-footed booby Sula nebouxii (Milne-Edwards, 1882 in Lobos de Afuera and Lobos de Tierra, the peruvian pelican Pelecanus thagus (Molina, 1782 in Lobos de Afuera, and with the Humboldt penguin Spheniscus humboldti (Meyen, 1834 in Foca. Egg predation and kleptoparasitism of S. nebouxii was common for this species in the three islands. Regarding the selection of nesting areas, it was noted that the Kelp Gull used different types of substrates such as rock, gravel, flagstone, boulders and seashells and that the nests were built using the resources of the site, mainly seaweeds and feathers and, in the Foca case, using leaves from sapote Capparis scabrida (Kunth, 1821. The nests were located in high and windy areas of the islands next to cracks and large rocks, from slopes of less than 15º to cliffs. Apparently, the timing of nest initiation was the same in the three islands, starting around the third week of October; in most cases were found three eggs in the nests. Factors are discussed that could affect the biological characteristics of the Kelp Gull in northern Peru and its differences with other breeding areas.

    Herbal and dietary supplements for weight loss and in treatment of obesity are growing in popularity and acceptance in the United States. Most of these supplements can be obtained over the counter and can have serious adverse effects associated with their consumption. We describe 2 patients who developed thyrotoxic hypokalemic periodic paralysis 2-3 weeks after consuming thyroxine-containing weight-loss supplements. This is the first known case of thyrotoxic hypokalemic periodic paralysis secondary to dietary supplements. It is important that patients and physicians are aware of the severe adverse reactions associated with dietary supplements. Physicians should as a routine inquire about herbal and dietary supplement consumption during all patient encounters.

    2011-09-01

    Herbal drugs are gaining worldwide prominence due to their distinct advantages. Developing countries have started exploring the ethnopharmacological approach of drug discovery and have begun to file patents on herbal drugs. The expansion of R&D in Indian herbal research organizations and presence of manufacturing units at non-Indian sites is an indication of the capability to develop new products and processes. The present study attempts to identify innovations in the Indian herbal drug sector by analyzing the patenting trends in India, US and EU. Based on key word and IPC based search at the IPO, USPTO, Esp@cenet and WIPO databases, patent applications and grant in herbal drugs by Indian applicants/assignees was collected for the last ten years (from 1st January 2001 to 31st October 2010). From this collection patents related to human therapeutic use only were selected. Analysis was performed to identify filing trends, major applicants/assignees, disease area and major plant species used for various treatments. There is a gradual increase in patent filing through the years. In India, individual inventors have maximum applications and grants. CSIR, among research organizations and Hindustan Unilever, Avesthagen, Piramal Life Science, Sahajanand Biotech and Indus Biotech among the companies have the maximum granted patents in India, US and EU respectively. Diabetes, cancer and inflammatory disorders are the major areas for patenting in India and abroad. Recent patents are on new herbal formulations for treatment of AIDS, hepatitis, skin disorders and gastrointestinal disorders. A majority of the herbal patents applications and grants in India are with individual inventors. Claim analysis indicates that these patents include novel multi-herb compositions with synergistic action. Indian research organizations are more active than companies in filing for patents. CSIR has maximum numbers of applications not only in India but also in the US and EU. Patents by research

  8. A novel phytomyxean parasite associated with galls on the bull-kelp Durvillaea antarctica (Chamisso Hariot.

    Directory of Open Access Journals (Sweden)

    Franz Goecke

    Full Text Available Durvillaea antarctica (Fucales, Phaeophyceae is a large kelp of high ecological and economic significance in the Southern Hemisphere. In natural beds along the central coast of Chile (Pacific Ocean, abnormal growth characterized by evident gall development and discolorations of the fronds/thallus was observed. Analysing these galls by light microscopy and scanning electron microscopy revealed the presence of endophytic eukaryotes showing typical characteristics for phytomyxean parasites. The parasite developed within enlarged cells of the subcortical tissue of the host. Multinucleate plasmodia developed into many, single resting spores. The affiliation of this parasite to the Phytomyxea (Rhizaria was supported by 18S rDNA data, placing it within the Phagomyxida. Similar microorganisms were already reported once 23 years ago, indicating that these parasites are persistent and widespread in D. antarctica beds for long times. The symptoms caused by this parasite are discussed along with the ecological and economic consequences. Phytomyxean parasites may play an important role in the marine ecosystem, but they remain understudied in this environment. Our results demonstrate for the first time the presence of resting spores in Phagomyxida, an order in which resting spores were thought to be absent making this the first record of a phagomyxean parasite with a complete life cycle so far, challenging the existing taxonomic concepts within the Phytomyxea. The importance of the here described resting spores for the survival and ecology of the phagomyxid parasite will be discussed together with the impact this parasite may have on 'the strongest seaweed of the world', which is an important habitat forming and economic resource from the Southern Hemisphere.

  9. Herbal medicinals: selected clinical considerations focusing on known or potential drug-herb interactions.

    Science.gov (United States)

    Miller, L G

    1998-11-09

    Herbal medicinals are being used by an increasing number of patients who typically do not advise their clinicians of concomitant use. Known or potential drug-herb interactions exist and should be screened for. If used beyond 8 weeks, Echinacea could cause hepatotoxicity and therefore should not be used with other known hepatoxic drugs, such as anabolic steroids, amiodarone, methotrexate, and ketoconazole. However, Echinacea lacks the 1,2 saturated necrine ring associated with hepatoxicity of pyrrolizidine alkaloids. Nonsteroidal anti-inflammatory drugs may negate the usefulness of feverfew in the treatment of migraine headaches. Feverfew, garlic, Ginkgo, ginger, and ginseng may alter bleeding time and should not be used concomitantly with warfarin sodium. Additionally, ginseng may cause headache, tremulousness, and manic episodes in patients treated with phenelzine sulfate. Ginseng should also not be used with estrogens or corticosteroids because of possible additive effects. Since the mechanism of action of St John wort is uncertain, concomitant use with monoamine oxidase inhibitors and selective serotonin reuptake inhibitors is ill advised. Valerian should not be used concomitantly with barbiturates because excessive sedation may occur. Kyushin, licorice, plantain, uzara root, hawthorn, and ginseng may interfere with either digoxin pharmacodynamically or with digoxin monitoring. Evening primrose oil and borage should not be used with anticonvulsants because they may lower the seizure threshold. Shankapulshpi, an Ayurvedic preparation, may decrease phenytoin levels as well as diminish drug efficacy. Kava when used with alprazolam has resulted in coma. Immunostimulants (eg, Echinacea and zinc) should not be given with immunosuppressants (eg, corticosteroids and cyclosporine). Tannic acids present in some herbs (eg, St John wort and saw palmetto) may inhibit the absorption of iron. Kelp as a source of iodine may interfere with thyroid replacement therapies. Licorice

    Various alcoholic beverages containing different concentrations of ethanol are widely consumed, and excessive alcohol consumption may result in serious health problems. The consumption of alcoholic beverages is often accompanied by non-alcoholic beverages, such as herbal infusions, tea and carbonated beverages to relieve drunk symptoms. The aim of this study was to supply new information on the effects of these beverages on alcohol metabolism for nutritionists and the general public, in order to reduce problems associated with excessive alcohol consumption. The effects of 57 kinds of herbal infusions, tea and carbonated beverages on alcohol dehydrogenase and aldehyde dehydrogenase activity were evaluated. Generally, the effects of these beverages on alcohol dehydrogenase and aldehyde dehydrogenase activity are very different. The results suggested that some beverages should not be drank after excessive alcohol consumption, and several beverages may be potential dietary supplements for the prevention and treatment of problems related to excessive alcohol consumption.

    The herbal mixtures, Essiac and Flor-Essence, are sold as nutritional supplements and used by patients to treat chronic conditions, particularly cancer. Evidence of anticancer activity for the herbal teas is limited to anecdotal reports recorded for some 40 years in Canada. Individual case reports suggest that the tea improves quality of life, alleviates pain, and in some cases, impacts cancer progression among cancer patients. Experimental studies with individual herbs have shown evidence of biological activity including antioxidant, antioestrogenic, immunostimulant, antitumour, and antiocholeretic actions. However, research that demonstrates these positive effects in the experimental setting has not been translated to the clinical arena. Currently, no clinical studies of Essiac or Flor-essence are published, but a clinical study is being planned at the British Columbia Cancer Agency by the University of Texas-Center for Alternative Medicine (UT-CAM) and Tzu-Chi Institute for Complementary and Alternative Medicine.

    2011-03-01

    Full Text Available Abstract Introduction Autism is a complex neurodevelopmental disorder in which the interactions of genetic, epigenetic and environmental influences are thought to play a causal role. In humans, throughout embryonic and fetal life, brain development is exquisitely susceptible to injury caused by exposure to toxic chemicals present in the environment. Although the use of herbal supplements during pregnancy is relatively common, little information is available on their association with fetal neurodevelopment. This is, to the best of our knowledge, the first report in the literature to associate a new plausible mechanism of neurodevelopmental toxicity with a case of autism spectrum disorder through a vitamin deficiency potentiated by concomitant use of herbal supplements and ethanol exposure. Case presentation We describe the pediatric environmental history of a three-year-old Caucasian girl with an autism spectrum disorder. We utilized her pediatric environmental history to evaluate constitutional, genetic, and environmental factors pertinent to manifestation of neurodevelopment disorders. Both parents reported prenatal exposure to several risk factors of interest. A year prior to conception the mother began a weight loss diet and ingested 1200 mg/day of 'horsetail' (Equisetum arvense herbal remedies containing thiaminase, an enzyme that with long-term use can lead to vitamin deficiency. The mother reported a significant weight loss during the pregnancy and a deficiency of B-complex vitamins. Thiamine (vitamin B1 deficiency could have been potentiated by the horsetail's thiaminase activity and ethanol exposure during pregnancy. No other risk factors were identified. Conclusions A detailed and careful pediatric environmental history, which includes daily intake, herbal remedies and ethanol exposure, should be obtained from all patients with autism spectrum disorder. Maternal consumption of ethanol and of herbal supplements with suspected or

  17. The Comparative effects of synthetic choline and herbal choline on hepatic lipid metabolism in broilers

    Directory of Open Access Journals (Sweden)

    G.R.Gangane1

    Full Text Available An experiment of 0-42 days in day old 150 Vencobb broiler chickens was conducted to determine comparative effects of synthetic choline and herbal sources of choline on hepatic lipid metabolism in broilers. Birds were randomly distributed into three groups (T0- T2, one untreated control and two treatments. Chicks in Group T0 were given feed without any additional source choline chloride. Chicks of Group T1 were fed with feed mixed with herbal product (Repchol supplied by Ayurvet Ltd., Baddi, India @ 500gm/tonne of feed and T2 was given combination of synthetic choline chloride@1kg/tonne (60% and biotin @ 150 mg/ton of feed. To study the effect of inclusion of herbal sources of choline and synthetic choline on hepatic lipid metabolism, serum triglycerides and cholesterol were estimated on day 21st and 42nd of experimental study. Gross pathological changes in liver were recorded on representative birds per group at the end of the study. It was recorded that inclusion of either synthetic choline or herbal source of choline exerted a hypocholesterolemic effect and also decreased the level of triglycerides as compared to untreated control thus minimizing the incidence of fatty liver, however the two treatment do not differ significantly. Gross pathological study also revealed no significant changes in the architecture of liver as compared to control. It can be concluded that the herbal supplements can successfully replace their synthetic analogues from broiler ration. [Veterinary World 2010; 3(7.000: 318-320

  20. Dietary supplements and functional foods: 2 sides of a coin?

    Science.gov (United States)

    Halsted, Charles H

    2003-04-01

    Dietary supplements are used by more than one-half of the adult US population. In contrast to pharmaceuticals, dietary supplements may be sold in the United States with little regulation other than listing of ingredients and the potential health benefits. By contrast, herbal products in Germany are carefully regulated by the same standards as drugs, and efforts are under way to standardize their regulation in the entire European Union. Most herbal users do not inform their physicians that they are taking these supplements, and most physicians do not inquire. Although some herbal products have clinically proven benefits, it is increasingly apparent that many contain potentially toxic substances, particularly in relation to interactions with drugs. Hence, it is essential that practicing physicians develop a working knowledge of herbals-specifically, about claims for their usage and potential or proven efficacies and toxicities-and that they incorporate such knowledge into the evaluation and management of their patients. By contrast, functional foods-integral components of the diet that are understood to contribute added health benefits-are the subject of intense and widespread research in food and nutritional science. Examples include many polyphenolic substances, carotenoids, soy isoflavones, fish oils, and components of nuts that possess antioxidant and other properties that decrease the risk of vascular diseases and cancer. Practicing physicians are advised to stay abreast of these emerging findings in order to best advise their patients on the value of health-promoting diets in disease prevention.

    Fatty liver disease is potentially a reversible condition that may lead to end-stage liver disease. Since herbal medicines such as Crataegus pinnatifida and Salvia miltiorrhiza have increasingly been used in the management of fatty liver disease, a systematic review on herbal medicine for fatty liver disease is needed. To assess the beneficial and harmful effects of herbal medicines for people with alcoholic or non-alcoholic fatty liver disease. We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 3, 2012), MEDLINE, EMBASE, and Science Citation Index Expanded to 1 March 2012. We also searched the Chinese BioMedical Database, Traditional Chinese Medical Literature Analysis and Retrieval System, China National Knowledge Infrastructure, Chinese VIP Information, Chinese Academic Conference Papers Database and Chinese Dissertation Database, and the Allied and Complementary Medicine Database to 2 March 2012. We included randomised clinical trials comparing herbal medicines with placebo, no treatment, a pharmacological intervention, or a non-pharmacological intervention such as diet or lifestyle, or Western interventions in participants with fatty liver disease. Two review authors extracted data independently. We used the 'risk of bias' tool to assess the risk of bias of the included trials. We assessed the following domains: random sequence generation, allocation concealment, blinding, incomplete outcome data, selective outcome reporting, and other sources of bias. We presented the effects estimates as risk ratios (RR) with 95% confidence intervals (CI) or as mean differences (MD) with 95% CI, depending on the variables of the outcome measures. We included 77 randomised clinical trials, which included 6753 participants with fatty liver disease. The risks of bias (overestimation of benefits and underestimation of harms) was high in all trials. The mean sample size was 88 participants

    Recently, there is a greater global interest in non synthetic, natural medicines derived from plant sources due to better tolerance and minimum adverse drug reactions as compared to synthetic medicines. Herbal products are also commonly used by the patients with certain chronic medical conditions, including breast cancer, liver disease, human immunodeficiency, asthma and rheumatological disorders. WHO estimates that about three-quarters of the world's population currently uses herbs and other forms of traditional medicines for the treatment of various diseases. The herbs are formulated in different modern dosage forms, such as Tablets, Capsules, Topical cream, Gel, Ointment and even some novel drug delivery forms, like extended release, sustained release, and microencapsules dosage forms. Patenting of herbal formulations has increased over the past few years and scientific evidence of therapeutic activity has been reported by performing various in vitro and in vivo experiments. This manuscript deals with various patented herbal formulations with their therapeutic application against various diseases.

    Cho, B H

    2000-08-01

    Hanbang, the Korean medical practice with origins in classical Chinese texts, is a prominent part of the Korean health care system. Hanbang physicians, called hanuisas, are looked down on by biomedical doctors, but their practice has enjoyed increasing popularity for several decades. As the market for herbal preparations has become more lucrative, biomedical pharmacists have begun to participate in it. The Pharmaceutical Act in 1993 explicitly allowed pharmacists to prescribe and dispense herbal drugs. This provoked a bitter public conflict between hanuisas and pharmacists, involving street demonstrations and strikes. The hanuisas asserted that the pharmacists were unqualified to assume their traditional practice. They also agitated for recognition in the state-sponsored system of health care and for the state's support for developing Hanbang medicine. This paper attributes the conflicts concerning Hanbang to the expanding market for herbal preparations, Korean nationalism, and to the oversupply of biomedical pharmacists.

    Full Text Available Abstract Background Although many health care professionals (HCPs in the United States have been educated about and recommend dietary supplements, little is known about their personal use of dietary supplements and factors associated with their use. Methods We surveyed HCPs at the point of their enrollment in an on-line course about dietary supplements between September, 2004 and May, 2005. We used multivariable logistic regression to analyze demographic and practice factors associated with use of dietary supplements. Results Of the 1249 health care professionals surveyed, 81 % reported having used a vitamin, mineral, or other non-herbal dietary supplements in the last week. Use varied by profession with highest rates among nurses (88%, physician assistants or nurse practitioners (84 % and the lowest rates among pharmacists (66% and trainees (72%. The most frequently used supplements were multivitamins (60%, calcium (40%, vitamin B (31%, vitamin C (30%, and fish oil (24%. Factors associated with higher supplement use were older age, female, high knowledge of dietary supplements, and discussing dietary supplements with patients. In our adjusted model, nurses were more likely than other professionals to use a multivitamin and students were more likely to use calcium. Conclusion Among HCPs enrolled in an on-line course about dietary supplements, women, older clinicians, those with higher knowledge and those who talk with patients about dietary supplements had higher use of dietary supplements. Additional research is necessary to understand the impact of professionals' personal use of dietary supplements on communication with patients about them.

    This study evaluated the effects of two Korean traditional plant extracts (Diospyros kaki THUNB. leaf; DK, and Nelumbo nucifera leaf; NN) on the fermentation, functional and sensory properties of herbal yogurts. Compared to control fermentation, all plant extracts increased acidification rate and reduced the time to complete fermentation (pH 4.5). Supplementation of plant extracts and storage time were found to influence the characteristics of the yogurts, contributing to increased viability of starter culture and phenolic compounds. In particular, the increase in the counts of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus was highest (2.95 and 1.14 Log CFU/mL respectively) in DK yogurt. Furthermore, supplementation of the plant extracts significantly influenced to increase the antioxidant activity and water holding capacity and to produce volatile compounds. The higher antioxidant activity and water holding capacity were observed in NN yogurt than DK yogurt. Moreover, all of the sensory characteristics were altered by the addition of plant extracts. Addition of plant extracts increased the scores related to flavor, taste, and texture from plain yogurt without a plant extract, as a result of volatile compounds analysis. Thus, the overall preference was increased by plant extracts. Consequently, supplementation of DK and NN extracts in yogurt enhanced the antioxidant activity and physical property, moreover increased the acceptability of yogurt. These findings demonstrate the possibility of using plant extracts as a functional ingredient in the manufacture of herbal yogurt.

    Understanding processes that drive sudden shifts in ecosystem structure and function has become an important research focus for coastal management. In kelp bed ecosystems, regime shifts occur when high densities of sea urchins destructively graze kelp and create coralline algal barrens. While the importance of predation and disease in mediating shifts between kelp beds and barrens on shallow rocky reefs has been well documented, little is known about the role of deep-living urchins in these alternative stable-state dynamics. In this study, we test the hypothesis that deep-living urchins along the central Atlantic coast of Nova Scotia move onshore and trigger shifts from kelp beds to barrens on shallow rocky reefs. We documented urchin distribution and abundance using tow-camera surveys down to 140 m depth and spanning 140 km of coast and created a predictive species-distribution model using these observations and spatial data on environmental factors that likely delineate suitable habitat for urchins. We used a random forest model to generate our predictions, which correctly classified 91% of observations into a positive or negative occurrence of urchins. Sea urchins predominantly occurred within 1.5 km of shore, in depressions and flat habitats between 40 and 85 m depth. We found that shallow regions where destructive grazing fronts have been documented over the past four decades were closer to deep-living sea urchin habitats compared to regions that remained in a kelp bed state during the same period. This supports our prediction that deep-living urchins play an important role in driving shallow regime shift dynamics, and indicates that their distribution can help identify areas of coast that are most vulnerable to a collapse to barrens.

    Herbal products are commonly used to treat clinical conditions and are often purchased online without the supervision of a healthcare provider. The use of herbals remains controversial because of widespread exaggerated claims of clinical efficacy and safety. We conducted an online search of 13 common herbals (including black cohosh, echinacea, garlic, ginkgo, ginseng, green tea, kava, saw palmetto, and St John's wort) and reviewed the top 50 Web sites for each using a Google search. We analyzed clinical claims, warnings, and other safety information. A total of 1179 Web sites were examined. Less than 8% of retail sites provided information regarding potential adverse effects, drug interactions, and other safety information; only 10.5% recommended consultation with a healthcare professional. Less than 3% cited scientific literature to accompany their claims. Key safety information is still lacking from many online sources of herbal information. Certain nonretail site types may be more reliable, but physicians and other healthcare professionals should be aware of the variable quality of these sites to help patients make more informed decisions.

    People diagnosed with cancer often self-administer complementary and alternative medicines (CAMs) to supplement their conventional treatments, improve health, or prevent recurrence. Flor-Essence{reg_sign} and Essiac{reg_sign} Herbal Tonics are commercially available complex mixtures of herbal extracts sold as dietary supplements and used by cancer patients based on anecdotal evidence that they can treat or prevent disease. In this study, we evaluated Flor-Essence{reg_sign} and Essiac{reg_sign} for their effects on the growth of human tumor cells in culture. The effect of Flor-Essence{reg_sign} and Essiac{reg_sign} herbal tonics on cell proliferation was tested in MCF-7, MDA-MB-436, MDA-MB-231, and T47D cancer cells isolated from human breast tumors. Estrogen receptor (ER) dependent activation of a luciferase reporter construct was tested in MCF-7 cells. Specific binding to the ER was tested using an ICI 182,780 competition assay. Flor-Essence{reg_sign} and Essiac{reg_sign} herbal tonics at 1%, 2%, 4% and 8% stimulated cell proliferation relative to untreated controls and activated ER dependent luciferase activity in MCF-7 cells. A 10{sup -7} M concentration of ICI 870,780 inhibited the induction of ER dependent luciferase activity by Flor-Essence{reg_sign} and Essiac{reg_sign}, but did not affect cell proliferation. Flor-Essence{reg_sign} and Essiac{reg_sign} Herbal Tonics can stimulate the growth of human breast cancer cells through ER mediated as well as ER independent mechanisms of action. Cancer patients and health care providers can use this information to make informed decisions about the use of these CAMs.

    This study evaluates the ecosystem structure and function of the nearshore reefs in the Lidao coastal ecosystem of northern China, a region of intensive kelp aquaculture, and fisheries enhancements, including the deployment of artificial reefs and release of cultured marine species. An Ecopath model, with 20 functional groups representing 81 species, was developed for a representative area in the region and Ecosim was used to explore two scenarios for alternative fishing practices and surrounding aquaculture activities. The mean trophic levels (TLs) of the functional groups ranged from 1.0 for the primary producers (phytoplankton, benthic algae and seagrass) and detritus to 4.14 for Type III fishes (fishes found in the water column above the artificial reefs, e.g., Scomberomorus niphonius). The mean transfer efficiency through the whole system was 11.7%, and the ecosystem had a relative low maturity, stability and disturbance resistance, indicating that it was at a developing stage. Nearly half of the total system biomass (48.9% of 620.20 t km-2 year-1), excluding detritus, was comprised of benthic finfish and invertebrates. The total yield from all fisheries (86.82 t/km2/year) was dominated by low trophic level herbivorous and detritivorous species, such as the sea cucumber Apostichopus japonicus (TL = 2.1, 46.07%), other echinoderms (sea urchins Asterias amurensis and Strongylocentrotus nudus, TL = 2.1, 34.6%) and abalone Haliotis discus hannai (TL = 2.0, 18.4%), and as a consequence, the mean TL of the catch was low (2.1). The results from the Ecosim simulation of closing all fisheries for 20 years predicted an increase of about 100% in the relative biomass of the main exploited species, A. japonicus and H. discus hannai. The simulated removal of all kelp farms over 10 years resulted in a two fold increase in the relative biomass of Type III fishes and a 120% increase in their main prey (i.e. Small pelagic fish), while the relative biomass of A. japonicus and

    The purpose of this review is to summarize the effectiveness, modes of action and commercial application of herbal plants and their derivatives as growth promoters for animal. Feed supplements are a group of feed ingredients that can cause a desired animal response in a non-nutrient role such as pH shift, growth, or metabolic modifier (Hutjens, 1991). Common feed additives used in animal diets include immunostimulators, antimicrobials, antioxidants, pH control agents and enzymes. Herbal plants, are a new class of growth promoters and in recent years this feed additives have gained extensive attention in the feed industry. They are a wide variety of herbs, spices, and products derived thereof, and are mainly essential oils. Although numerous reports have demonstrated antioxidative and antimicrobial and immune stimulation efficacy in vitro, respective experimental in vivo evidence is still quite limited. A limited number of experimental comparisons of herbal plants feed additives with antibiotics or organic acid have suggested similar effects on the animal gut microflora. Gut microflora has significant effects on host nutrition, health, and growth performance by interacting with nutrient utilization and the development of gut system of the host. In addition, some phytogenic compounds seem to promote intestinal mucus production. However, the future of using herbs in animal feeding will in great measure depend on the knowledge of chemical structure, their value and characteristics of practical herbs or their extract physiological needs and well-being of animal, and, above all on consumer's preferences and expectations.

    Extracellular recordings from the mixed sensory nerves innervating the abraded dactylopodites of the kelp crab, Pugettia producta (Randall), indicate that at least some chemoreceptors and mechanoreceptors remain functional. The chemoreceptors of the abraded dactyls are sensitive to both the concentration and chemical nature of the stimulants. The responses of the chemoreceptors, but not of the mechanoreceptors, are reduced when choline is substituted for sodium in the stimulant solutions. Only chemoreception is blocked by the topical application of tetrodotoxin (TTX) to the dactyls; partial reversal of the blockage occurs with time. The differential blockage of receptor activity by low Na/sup +/ and TTX is consistent with the idea that spike initiation occurs more distally in the dendrites of the chemosensory neurons than in the mechanosensory neurons. The relevance of this to the ability of at least some abraded dactyl setae to remain functional in a long-lived, nonmolting crab is considered.

    Full Text Available Predicting consequences of ocean deoxygenation and ocean acidification for nearshore marine ecosystems requires baseline dissolved oxygen (DO and carbonate chemistry data that are both high-frequency and high-quality. Such data allow accurate assessment of environmental variability and present-day organism exposure regimes. In this study, scales of DO and pH variability were characterized over one year in a nearshore kelp forest ecosystem in the Southern California Bight. DO and pH were strongly, positively correlated, revealing that organisms on this upwelling shelf are not only exposed to low pH but also to low DO. The dominant scale of temporal DO and pH variability occurred on semidiurnal, diurnal and event (days–weeks time scales. Daily ranges in DO and pH at 7 m water depth (13 mab could be as large as 220 μmol kg−1 and 0.36 units, respectively. Sources of pH and DO variation include photosynthesis within the kelp forest ecosystem, which can elevate DO and pH by up to 60 μmol kg−1 and 0.1 units over one week following the intrusion of high-density, nutrient-rich water. Accordingly, highly productive macrophyte-based ecosystems could serve as deoxygenation and acidification refugia by acting to elevate DO and pH relative to surrounding waters. DO and pH exhibited greater spatial variation over a 10 m increase in water depth (from 7 to 17 m than along a 5 km stretch of shelf in a cross-shore or alongshore direction. Over a three-month time period, mean DO and pH at 17 m water depth were 168 μmol kg−1 and 7.87, respectively. These values represent a 35% decrease in mean DO and 37% increase in [H+] relative to near-surface waters. High-frequency variation was also reduced at depth. The mean daily range in DO and pH was 39% and 37% less, respectively, at 17 m water depth relative to 7 m. As a consequence, the exposure history of an organism is largely a function of its depth of occurrence

    The first definition of food supplements in France was established by decree 96-307 of April 10th 1996. In 2002, the European Community adopted a regulation for food supplements (European Directive 2002/46/CE June 10th). This was an important event in the regulation of food supplements. The European regulation was adopted in France, with some modifications, by decree 2006-352 of March 20th 2006. The European Regulation on food supplements is more defined than those for any other food types and is exemplary. The Regulation on addition of vitamins and minerals to food differs from the regulation on the addition of other substances such as amino acids, essential fatty acids, fibers, carbohydrates, various plant, and herbal extracts. While the Regulation includes vitamins and minerals to the positive list of supplements, other substances are included in the negative list of supplements. According to the Regulation, substances added to food supplements must have a nutritional or physiological effect. The increased use of food supplements led to the creation of a department specialized in the safety of food supplement. The safety of food supplements is a permanent concern for sanitary authorities. These authorities have recently combined scientific methodological approaches and a collective expertise to implement and monitor simple and useful rules that insure consumer's safety. Safety laws aim to protect the consumers of food supplements.

  13. Increased Wounding of Southern Right Whale (Eubalaena australis Calves by Kelp Gulls (Larus dominicanus at Peninsula Valdes, Argentina.

    Directory of Open Access Journals (Sweden)

    Carina F Marón

    Full Text Available At least 626 southern right whale (Eubalaena australis calves died at the Península Valdés calving ground, Argentina, between 2003 and 2014. Intense gull harassment may have contributed to these deaths. In the 1970s, Kelp Gulls (Larus dominicanus began feeding on skin and blubber pecked from the backs of living right whales at Valdés. The frequency of gull attacks has increased dramatically over the last three decades and mother-calf pairs are the primary targets. Pairs attacked by gulls spend less time nursing, resting and playing than pairs not under attack. In successive attacks, gulls open new lesions on the whales' backs or enlarge preexisting ones. Increased wounding could potentially lead to dehydration, impaired thermoregulation, and energy loss to wound healing. The presence, number and total area of gull-inflicted lesions were assessed using aerial survey photographs of living mother-calf pairs in 1974-2011 (n = 2680 and stranding photographs of dead calves (n = 192 in 2003-2011. The percentage of living mothers and calves with gull lesions increased from an average of 2% in the 1970s to 99% in the 2000s. In the 1980s and 1990s, mothers and calves had roughly equal numbers of lesions (one to five, but by the 2000s, calves had more lesions (nine or more covering a greater area of their backs compared to their mothers. Living mother-calf pairs and dead calves in Golfo Nuevo had more lesions than those in Golfo San José in the 2000s. The number and area of lesions increased with calf age during the calving season. Intensified Kelp Gull harassment at Península Valdés could be compromising calf health and thereby contributing to the high average rate of calf mortality observed in recent years, but it cannot explain the large year-to-year variance in calf deaths since 2000.

    We investigated patterns of genetic structure in two sister kelp species to explore how distribution width along the shore, zonation, latitudinal distribution and historical factors contribute to contrasting patterns of genetic diversity. We implemented a hierarchical sampling scheme to compare patterns of genetic diversity and structure in these two kelp species co-distributed along the coasts of Brittany (France) using a total of 12 microsatellites, nine for Laminaria hyperborea and 11 for Laminaria digitata, of which eight amplified in both species. The genetic diversity and connectivity of L. hyperborea populations were greater than those of L. digitata populations in accordance with the larger cross-shore distribution width along the coast and the greater depth occupied by L. hyperborea populations in contrast to L. digitata populations. In addition, marginal populations showed reduced genetic diversity and connectivity, which erased isolation-by-distance patterns in both species. As L. digitata encounters its southern range limit in southern Brittany (SBr) while L. hyperborea extends down to mid-Portugal, it was possible to distinguish the effect of habitat continuity from range edge effects. We found that L. digitata did not harbour high regional diversity at its southern edge, as expected in a typical rear edge, suggesting that refuges from the last glacial maximum for L. digitata were probably not located in SBr, but most likely further north. For both species, the highest levels of genetic diversity were found in the Iroise Sea and Morlaix Bay, the two regions in which they are being currently harvested. Preserving genetic diversity of these two foundation species in these areas should, thus, be a priority for the management of this resource in Brittany.

    Wild populations of brown marine algae (Phaeophyta) provide extensive surfaces to bacteria and epiphytic eukaryotes for colonization. On one hand, various strategies allow kelps prevent frond surface fouling which would retard growth by reducing photosynthesis and increasing pathogenesis. On the other hand, production and release of organic exudates of high energy value, sometimes in association with more or less selective control of settlement of epiphytic strains, allow bacteria to establish surface consortia not leading to macrofouling. Here, we present the analysis of adhesion and biofilm formation of bacterial isolates from the kelp Laminaria digitata and of characterized and referenced marine isolates. When they were grown in flow cell under standard nutrient regimes, all used bacteria, except one, were able to adhere on glass and then develop as biofilms, with different architecture. Then, we evaluated the effect of extracts from undisturbed young Laminaria thalli and from young thalli subjected to oxidative stress elicitation; this latter condition induced the production of defense molecules. We observed increasing or decreasing adhesion depending on the referenced strains, but no effects were observed against strains isolated from L. digitata. Such effects were less observed on biofilms. Our results suggested that L. digitata is able to modulate its bacterial colonization. Finally, mannitol, a regular surface active component of Laminaria exudates was tested individually, and it showed a pronounced increased on one biofilm strain. Results of these experiments are original and can be usefully linked to what we already know on the oxidative halogen metabolism peculiar to Laminaria. Hopefully, we will be able to understand more about the unique relationship that bacteria have been sharing with Laminaria for an estimated one billion years.

    Many Americans, not completely satisfied with traditional western medicine, have turned to alternative and complementary medicine which explains the increasing popularity of the herbal products and the Chinese herbal medicine. The lack of government regulations and the increasing advertisements by the manufactures have created an impression to the common public that the natural herbal remedies are inherently safer and cheaper than conventional medicine. The skyrocketing rise of healthcare cost and the adverse reaction and side effects incurred from the prescribed drugs have both reinforced such an impression. Herbs in the USA and in many European countries have been prepared as capsules, tablets, teas, lozenges, juice extracts, tincture, and ointments. Most of the herbs are administered as a single herb in the USA and Europe. However, the traditional Chinese herbal medicine contains multiple active ingredients from various herbs and is prepared as concoctions by simmering them for hours to produce pharma-therapeutic properties useful for the treatment of a particular disease. Those prepared concoctions are taken gingerly with specific treatment purposes. In the USA and some European counties, herbs are distributed and labeled as dietary supplements and are taken by many individuals for a long period of time creating some medical and dental complex problems among them, especially in terms of anesthesia-surgery complications. This paper provides insight into basic differences in how herbs are prepared before administration to the patients in China versus a single unprepared herb sold in the USA and Europe. Also addressed are the interdisciplinary issues with health professionals, the proper regulations for better quality control of imported herbs, and the proper warning on the labels of the herbs.

    Full Text Available Background : Various hepatoprotective herbal products from plants are available in Mexico, where up to 85% of patients with liver disease use some form of complementary and alternative medicine. However, only few studies have reported on the biological evaluation of these products. Objective : Using a model of carbon tetrachloride (CCl4 -induced hepatotoxicity in rats, we evaluated the effects of commercial herbal extracts used most commonly in the metropolitan area of Monterrey, Mexico. Materials and Methods : The commercial products were identified through surveys in public areas. The effect of these products given with or without CCl4 in rats was evaluated by measuring the serum concentrations of aspartate amino transferase (AST and alanine amino transferase (ALT, and histopathological analysis. Legalon® was used as the standard drug. Results : The most commonly used herbal products were Hepatisan® capsules, Boldo capsules, Hepavida® capsules, Boldo infusion, and milk thistle herbal supplement (80% silymarin. None of the products tested was hepatotoxic according to transaminase and histological analyses. AST and ALT activities were significantly lower in the Hepavida+CCl4 -treated group as compared with the CCl4 -only group. AST and ALT activities in the silymarin, Hepatisan, and Boldo tea groups were similar to those in the CCl4 group. The CCl4 group displayed submassive confluent necrosis and mixed inflammatory infiltration. Both the Hepatisan+CCl4 and Boldo tea+CCl4 groups exhibited ballooning degeneration, inflammatory infiltration, and lytic necrosis. The silymarin+CCl4 group exhibited microvesicular steatosis. The Hepavida+CCl4 - and Legalon+CCL4 -treated groups had lower percentages of necrotic cells as compared with the CCl4 -treated group; this treatment was hepatoprotective against necrosis. Conclusion : Only Hepavida had a hepatoprotective effect.

  18. Efficacy, safety, quality control, marketing and regulatory guidelines for herbal medicines (phytotherapeutic agents

    Full Text Available This review highlights the current advances in knowledge about the safety, efficacy, quality control, marketing and regulatory aspects of botanical medicines. Phytotherapeutic agents are standardized herbal preparations consisting of complex mixtures of one or more plants which contain as active ingredients plant parts or plant material in the crude or processed state. A marked growth in the worldwide phytotherapeutic market has occurred over the last 15 years. For the European and USA markets alone, this will reach about $7 billion and $5 billion per annum, respectively, in 1999, and has thus attracted the interest of most large pharmaceutical companies. Insufficient data exist for most plants to guarantee their quality, efficacy and safety. The idea that herbal drugs are safe and free from side effects is false. Plants contain hundreds of constituents and some of them are very toxic, such as the most cytotoxic anti-cancer plant-derived drugs, digitalis and the pyrrolizidine alkaloids, etc. However, the adverse effects of phytotherapeutic agents are less frequent compared with synthetic drugs, but well-controlled clinical trials have now confirmed that such effects really exist. Several regulatory models for herbal medicines are currently available including prescription drugs, over-the-counter substances, traditional medicines and dietary supplements. Harmonization and improvement in the processes of regulation is needed, and the general tendency is to perpetuate the German Commission E experience, which combines scientific studies and traditional knowledge (monographs. Finally, the trend in the domestication, production and biotechnological studies and genetic improvement of medicinal plants, instead of the use of plants harvested in the wild, will offer great advantages, since it will be possible to obtain uniform and high quality raw materials which are fundamental to the efficacy and safety of herbal drugs.

    The medicinal use of herbs is a principal achievement of human ingenuity. The most renowned doctors of antiquity: Hippocrates, Dioscorides, Theophrastus, Pliny the Elder and Galen mentioned herbs in their works. The first printed herbal was published in Mainz in 1485. Outstanding scientists e.g. Otto Brunfels, Hieronymus Bock, Leonard Fuchs and Andreo Mattiola published herbals in the 16th century. Polish doctors also contributed to the development of herbal treatment. The first work: Of Herbs and their Potency by Stefan Falimirz, published in 1534, triggered other publications in the 16th century, the age of herbals. In 1542, Hieronymus Spiczynski published a herbal: Of Local and Overseas Herbs and their Potency. Then, in 1568, Marcin Siennik published his: Herbal, which is the Description of Local and Overseas Herbs, their Potency and Application. In 1595, Marcin of Urzedow published: The Polish Herbal, the Books of Herbs. Completed in mid-16th century, it was only published 22 years after his death. The last work discussed is Herbal Known in Latin as published in 1613 by Simon Syrenius a graduate of Ingolstadt and Padua universities and lecturer at the Academy of Krakow. The work was Europes most complete elaboration on herbal treatment. The herbs described in the herbals worked as diuretics, demulcents, analgesics, relaxants and preventives of kidney stones. Published in Polish, they are still to be found in Poland. All the works presented herein are held by the Library of the Seminary of Wloclawek, and the Ossolinski National Institute in Wroclaw.

    Full Text Available Herbal remedies are widely used for the treatment and prevention of various diseases and often contain highly active pharmacological compounds. Many medicinal herbs and pharmaceutical drugs are therapeutic at one dose and toxic at another. Toxicity related to traditional medicines is becoming more widely recognized as these remedies become popular in the Mediterranean region as well as worldwide. Most reports concerning the toxic effects of herbal medicines are associated with hepatotoxicity although reports of other toxic effects including kidney, nervous system, blood, cardiovascular and dermatologic effects, mutagenicity and carcinogenicity have also been published in the medical literature. This article presents a systematic review on safety of traditional Arab medicine and the contribution of Arab scholars to toxicology. Use of modern cell biological, biochemical, in vitro and in vivo techniques for the evaluation of medicinal plants safety is also discussed.

    In Iran, conventional production methods of herbal oils are widely used by local practitioners. Administration of oils is rooted in traditional knowledge with a history of more than 3000 years. Scientific evaluation of these historical documents can be valuable for finding new potential use in current medicine. The current study (i) compiled an inventory of herbal oils used in ancient and medieval Persia and (ii) compared the preparation methods and therapeutic applications of ancient times to current findings of medicinal properties in the same plant species. Information on oils, preparation methods and related clinical administration was obtained from ancient Persian documents and selected manuscripts describing traditional Persian medicine. Moreover, we investigated the efficacy of medicinal plant species used for herbal oils through a search of the PubMed, Scopus and Google Scholar databases. In Iran, the application of medicinal oils date back to ancient times. In medieval Persian documents, 51 medicinal oils produced from 31 plant species, along with specific preparation methods, were identified. Flowers, fruits and leaves were most often used. Herbal oils have been traditionally administered via oral, topical and nasal routes for gastrointestinal, musculoskeletal, and neural diseases, respectively. According to current investigations, most of the cited medicinal plant species were used for their anti-inflammatory and analgesic properties. Medicinal oils are currently available in Iranian medicinal plant markets and are prepared using traditional procedures for desirable clinical outcomes. Other than historical clarification, the present study provides data on clinical applications of the oils that should lead to future opportunities to investigate their potential medicinal use.

    Herbal medicinal materials have been used worldwide for centuries to maintain health and to treat disease. However, adulteration of herbal medicines remains a major concern of users and industry for reasons of safety and efficacy. Identification of herbal medicinal materials by DNA technology has been widely applied,started from the mid-1990s. In recent years, DNA barcoding of global plant species using four standard barcodes (rbcL, matK, trnH-psbA and ITS) has been a major focus in the fields of biodiversity and conservation. These DNA barcodes can also be used as reliable tools to facilitate the identification of herbal medicinal materials for the safe use of herbs, quality control, and forensic investigation. Many studies have applied these DNA barcodes for the identification of herbal medicinal species and their adulterants. The present article reviews efforts in the identification of herbal medicinal materials using the standard DNA barcodes and other DNA sequence-based markers.

    2013-12-01

    To assess the constraints for Indian herbal drug industry with respect to manufacturing and commercialization of herbal medicines. A questionnaire-based survey was conducted to obtain primary data on challenges faced during production, commercialization, and marketing approval for traditional or herbal drugs in India and abroad. Responses were collected from 150 companies by email, telephone, and in-person interviews from June 2009 to August 2010 and were analyzed to draw appropriate conclusions. The survey result showed that differing regulatory requirements and the limited market in foreign countries are the major hindrances for exporting. Standardization and quality control of raw materials and herbal formulations emerged as the major challenge for Indian herbal drug manufacturing firms. Insufficient regulatory guidelines, particularly guidelines for good manufacturing practices; nonimplementation of good agricultural and collection practices; and weak implementation of the Drugs and Cosmetics Act of 1940 are considered major drawbacks for the Indian herbal industry. Proper implementation of the Drugs and Cosmetics Act of 1940, development of more elaborate guidelines on quality control aspects, and development of marker-based standards are needed to produce safe and effective herbal medicines in India. Because evidence-based studies are becoming increasingly essential for establishing the safety and efficacy of herbal products in the domestic and export market, more focus should be placed on scientific and technological advancement in the field of herbal medicine. Regulatory harmonization becomes essential to mitigate the delays in commercialization across countries.

    2001-04-01

    Herbal medicaments are in common use. In general, the judicious use of carefully selected and prepared herbal medications seems to cause few adverse effects and may be beneficial. However, toxic effects of these products have been reported with increasing frequency. Infants and children may be even more susceptible to some of the adverse effects and toxicity of these products because of differences in physiology, immature metabolic enzyme systems, and dose per body weight. Although information promoting the use of herbal medicine is widespread, true evidence-based information about the efficacy and safety of herbal medications is limited. Although the most conservative approach is to recommend against use of herbal medicine until such evidence is available, some patients are not receptive to this approach. A reasonable approach for health care providers may be to follow such use closely, assist in herbal therapeutic decisions, and monitor for adverse effects and interactions. This manuscript discusses general concepts about herbal medicines, public health implications, and a framework for mechanisms of adverse effects from the use of botanicals. Adverse effects and toxicity of selected herbal products, including Chinese herbal medicines, are presented. The authors propose a risk reduction approach in which physicians actively seek information about the use of complementary or alternative medicine while taking medical histories.

    Chinese herbal medicines, Inchinko-to, Bofu-tsusho-san and Dai-saiko-to, containing 3, 18 and 8 components, respectively, have since long been used as an anti-inflammatory, antipyretic, choleretic and diuretic agent for liver disorders and jaundice, as an anti-obesity agent, a hypocholesterolemic agent for liver disorders and a therapeutic and/or preventive agent for cholesterol gallstone disease with hypertriglycerid-emia in China and Japan, respectively. In the present study, we investigated the effects of these three herbal medicines in young male mice fed a high-fat diet. Plasma levels of lipids and the numbers of the fatty droplets in the liver cytoplasm were markedly lowered by the diets supplemented with three herbal medicines. The liver weights and the body growth were reduced by the diet supplemented with Dai-saiko-to, which slightly affected the concentrations of total protein, albumin, creatinine or calcium, and the activity of lactate dehydrogenase. Thus, Dai-saiko-to, besides Bofu-tsusho-san, seems effective in the activities of anti-obesity, anti-hyperlipidemia and anti-hyperlipids in liver cytoplasm, when used carefully.

    Ocean acidification (OA) is the reduction in seawater pH due to the absorption of human-released CO2 by the world’s oceans. The average surface oceanic pH is predicted to decline by 0.4 units by 2100. However, kelp metabolically modifies seawater pH via photosynthesis and respiration in some temperate coastal systems, resulting in daily pH fluctuations of up to ±0.45 units. It is unknown how these fluctuations in pH influence the growth and physiology of the kelp, or how this might change with OA. In laboratory experiments that mimicked the most extreme pH fluctuations measured within beds of the canopy-forming kelp Ecklonia radiata in Tasmania, the growth and photosynthetic rates of juvenile E. radiata were greater under fluctuating pH (8.4 in the day, 7.8 at night) than in static pH treatments (8.4, 8.1, 7.8). However, pH fluctuations had no effect on growth rates and a negative effect on photosynthesis when the mean pH of each treatment was reduced by 0.3 units. Currently, pH fluctuations have a positive effect on E. radiata but this effect could be reversed in the future under OA, which is likely to impact the future ecological dynamics and productivity of habitats dominated by E. radiata.

    Coastal communities worldwide rely on small-scale artisanal fisheries as a means of increasing food security and alleviating poverty. Even small-scale fishing activities, however, are prone to resource depletion and environmental degradation, which can erode livelihoods in the long run. Thus, there is a pressing need to identify viable and resilient artisanal fisheries, and generate knowledge to support management within the context of a rapidly changing climate. We examined the ecosystem-level consequences of an artisanal kelp fishery (Macrocystis pyrifera), finding small-scale harvest of this highly productive species poses minimal impacts on kelp recovery rates, survival, and biomass dynamics, and abundances of associated commercial and culturally important fish species. These results suggest that small-scale harvest poses minimal trade-offs for the other economic benefits provided by these ecosystems, and their inherent, spiritual, and cultural value to humans. However, we detected a negative impact of warmer seawater temperatures on kelp recovery rates following harvest, indicating that the viability of harvest, even at small scales, may be threatened by future increases in global ocean temperature. This suggests that negative impacts of artisanal fisheries may be more likely to arise in the context of a warming climate, further highlighting the widespread effects of global climate change on coastal fisheries and livelihoods.

    Resource managers are concerned that offshore oil platforms in the Southern California Bight may be contributing to environmental contaminants accumulated by marine fishes. To examine this possibility, 18 kelp bass (Paralabrax clathratus), 80 kelp rockfish (Sebastes atrovirens), and 98 Pacific sanddab (Citharichthys sordidus) were collected from five offshore oil platforms and 10 natural areas during 2005-2006 for whole-body analysis of 63 elements. The natural areas, which served as reference sites, were assumed to be relatively uninfluenced by contaminants originating from platforms. Forty-two elements were excluded from statistical comparisons for one of three reasons: they consisted of major cations that were unlikely to accumulate to potentially toxic concentrations under ambient exposure conditions; they were not detected by the analytical procedures; or they were detected at concentrations too low to yield reliable quantitative measurements. The remaining 21 elements consisted of aluminum, arsenic, barium, cadmium, chromium, cobalt, copper, gallium, iron, lead, lithium, manganese, mercury, nickel, rubidium, selenium, strontium, tin, titanium, vanadium, and zinc. Statistical comparisons of these 21 elements indicated that none consistently exhibited higher concentrations at oil platforms than at natural areas. Eight comparisons yielded significant interaction effects between total length (TL) of the fish and the two habitat types (oil platforms and natural areas). This indicated that relations between certain elemental concentrations (i.e., copper, rubidium, selenium, tin, titanium, and vanadium) and habitat type varied by TL of affected fish species. To better understand these interactions, we examined elemental concentrations in very small and very large individuals of affected species. Although significant interactions were detected for rubidium, tin, and selenium in kelp rockfish, the concentrations of these elements did not differ significantly between

    Publications linking hepatotoxicity to the use of herbal preparations are escalating. Herbal teas, traditional Chinese medicines (TCMs) and dietary supplements have been shown to contain pyrrolizidine alkaloids (PAs). Acute PA toxicosis of the liver can result in sinusoidal-obstruction syndrome, also known as veno-occlusive disease (VOD). This paper describes a sensitive and robust method for the detection of targeted PAs and their N-oxides (PANOs) in herbal products (selected herbal teas and TCMs) sourced within Ireland. The sample preparation includes a simple acidic extraction with clean-up via solid-phase extraction (SPE). Sample extracts were accurately analysed by using LC-ESI-MS/MS applying for the first time a pentafluorophenyl (PFP) core-shell column to the chromatographic separation of PAs and PANOs. The method was validated for selectivity, taking into consideration matrix effects, specificity, linearity, precision and trueness. Limits of detection (LOD) and limits of quantitation (LOQ) were quantified for all PAs and PANOs ranging from 0.4 to 1.9 µg kg⁻¹ and from 1.3 to 6.3 µg kg⁻¹, respectively. In this study 10 PAs and four PANOs were targeted because they are commercially available as reference standards. Therefore, this study can only report the levels of these PAs and PANOs analysed in the herbal teas and TCMs. The results reported represent the minimum levels of PAs and PANOs present in the samples analysed; commercially available herbal teas (n = 18) and TCMs (n = 54). A total of 50% herbal teas and 78% Chinese medicines tested positive for one or more PAs and/or PANOs included within this study, ranging from 10 to 1733 and from 13 to 3668 µg kg⁻¹, respectively.

Using a cross-sectional design, data were collected via face-to-face interview using structured questionnaire from convenience sample of adults from four towns in Malaysia. Multivariate logistic regression analysis was used to identify the significant predictors of herbal medicines use. From a total of 1601 respondents, 542 (33.9%) reported use of herbal medicines in the previous 12 months. Multivariate logistic regression analysis revealed the following variables to be predictive of herbal medicines use: female gender [odds ratio (OR) 1.80, confidence interval (CI) 1.40-2.31], being married [OR 1.97, CI 1.44-2.71], having health problems [OR 2.31, CI 1.74-3.07] and having high-income levels [OR 4.21, CI 1.72-10.30]. The odds of someone using herbal medicines also increases though slightly if someone has favorable opinions about herbal medicines on the aspects examined. On the other hand, being Chinese [OR 0.74, CI 0.57-0.96] and Indians [OR 0.17, CI 0.11-0.27] were associated with decreased odds of using herbal medicines compared to Malays. The prevalence of herbal medicines use is high. Respondents' personal attributes and opinions influence their likelihood of using herbal medicines. These findings are important because knowledge of the predictors of herbal medicines use may help health care providers to identify patients at increased risk who would be candidates for receiving guidance on safe use of herbal medicines.

    Ten years have passed since Directive 2004/24/EC regulating herbal medicinal products across the EU were published. The directive created the Committee on Herbal Medicinal Products within the European Medicines Agency whose remit includes the creation and publishing of official EU monographs on herbal medicinal products. These monographs include the official uses of the products and their evidence for efficacy and safety. To this effect, we are interested in analysing the potential impact herbal product EU monographs could have on the therapeutic treatment options available for prescribers in Malta. Therefore our aim was two-fold. First, to rationalise the spread of indications of the herbal substances listed in the community herbal monograph inventory and subsequently determine if these herbal substances could potentially contribute to the treatment options available in our local scenario (Malta). 128 EU monographs were analysed resulting in a total of 230 indications which subsequently codified into 42 unique ATC codes. The Malta Medicines List contains 1456 unique ATC codes. Comparative analysis of the Malta Medicines List revealed that the 21 therapeutic areas had 4 or less pharmaceutically used substances (5th level ATC codes) registered and therefore in our opinion are areas with limited therapeutic choice. The following 4 therapeutic areas, A05 bile and liver therapy, A13 tonics, A15 appetite stimulants and D03 preparations for treatment of wounds and ulcers, could potentially benefit from the registration of herbal medicinal products according to the EU herbal monographs. If such registration is effected the aforementioned areas would no longer be considered limited because more than 4 therapeutic choices would be available to prescribers. This study is the first study across the EU to analyse the potential impact of published EU herbal monographs on therapeutic coverage in an EU member state and confirms the notion that herbal products could potentially

    Safe alternative anticoccidial drug to chemical feed additives are herbal extracts, because they don't results to tissue residue and drug resistance. In order to evaluate the effects of herbal extracts to control avian coccidiosis, 180 one-day-old broiler chickens were randomly divided into nine equal groups, as follows: (1) Biarum bovei (2) Nectaroscordum tripedale( 3) Dorema aucheri (4) Cichorium intybus (5) Prangos ferulaceae (6) diclazuril (7) Artemisia absinthium (8) infected control (9) uninfected control (each contains two groups). Administration of herbal extracts and supplementation of diclazuril was began 2 days before challenge and lasted for the duration of the experiment. The chicks of all the groups except uninfected control group were inoculated orally with sporulated oocysts (3 × 10(3) oocysts of Eimeria tenella) on the day 22 of age. The criteria employed were: body weight, feed conversion ratio, blood in feces, survival rate, lesion scoring, number of oocyst output per gram feces and histopathological changes. For histopathological evaluation, on day 12 post inoculation three birds from each group were randomly selected and humanly sacrificed. N. tripedale and diclazuril revealed better results in terms of growth performance, lesion score, extent of bloody diarrhea and oocyst count as compared to other herbal extracts. The increase in the severity of lesions was observed in groups of D. aucheri, A. absinthium, B. bovei, P. ferulaceae, C. intybus, diclazuril and N. tripedale, respectively. In conclusion, the current study showed that herbal extracts were effective in control of coccidiosis caused by the E. tenella infection.

    Full Text Available Predicting consequences of ocean deoxygenation and ocean acidification for nearshore marine ecosystems requires baseline dissolved oxygen (DO and carbonate chemistry data that are both high-frequency and high-quality. Such data allow accurate assessment of environmental variability and present-day organism exposure regimes. In this study, scales of DO and pH variability were characterized over one year in a nearshore, kelp forest ecosystem in the Southern California Bight. DO and pH were strongly, positively correlated revealing that organisms on this upwelling shelf are not only exposed to low pH but also low DO. The dominant temporal scale of DO and pH variability occurred on semidiurnal, diurnal and event (days–weeks time scales. Daily ranges in DO and pH at 7 m water depth (13 mab could be as large as 220 μmol kg−1 and 0.36 units, respectively. This range is much greater than the expected decreases in pH in the open ocean by the year 2100. Sources of pH and DO variation include photosynthesis within the kelp forest ecosystem, which can elevate DO and pH by up to 60 μmol kg−1 and 0.1 units over one week following the intrusion of high-density, nutrient-rich water. Accordingly, highly productive macrophyte-based ecosystems could serve as deoxygenation and acidification refugia by acting to elevate DO and pH relative to surrounding waters. DO and pH exhibited greater spatial variation over a 10 m increase in water depth (from 7 to 17 m than along a 5-km stretch of shelf in a cross-shore or alongshore direction. Over a three-month time period mean DO and pH at 17-m water depth were 168 μmol kg−1 and 7.87, respectively. These values represent a 35% decrease in mean DO and 37% increase in [H+] relative to surface waters. High-frequency variation was also reduced at depth. The mean daily range in DO and pH was 39% and 37% less, respectively, at 17-m water depth relative to the surface. As a

    The aim of the study was to obtain rich qualitative data about the type of nutritional supplements and drinks consumed by adolescents, and the reasons for their consumption, with particular emphasis on the perceived benefits of nutritional supplementation. Semi-structured focus group interviews (n = 16) were conducted among 78 adolescents aged 11-18 years from a co-educational government high school. Participants reported consuming sports drinks, vitamin and mineral supplements, energy drinks, herbal supplements, guarana, creatine, high protein milk supplements, and coenzyme Q10. Reasons for supplement use included perceived short-term health benefits, prevention of illness, improved immunity, parental supply of supplements, taste, energy boost, better sports performance and to rectify a poor diet. Results suggest that some adolescents consume nutritional supplements, sports drinks and energy drinks for their perceived physiological benefits, and that they may not be aware of any potential risks. Health educators should be aware that adolescents seek specific health benefits from nutritional supplements and drinks, which may be better achieved through appropriate consumption of a nutritious diet. Health education programmes should incorporate the perceptions, aspirations and motivations of young people into the planning of interventions and activities in order to make them most relevant and effective.

    Plants and herbs have been used to induce abortions but there is very little published information describing the commonly used ones. The purpose of this report is to describe the herbal products used to induce abortions, and to enhance awareness and understanding of their toxic effects. A descriptive retrospective survey was conducted on the calls received by the Montevideo Poison Centre between 1986 and 1999 concerning the ingestion of herbal infusions with abortive intent. A total of 86 cases involving 30 different plant species were identified. The species most frequently involved were ruda (Ruta chalepensis/graveolens), cola de quirquincho (Lycopodium saururus), parsley (Petroselinum hortense), and an over-the-counter herbal product named Carachipita. The components of Carachipita are pennyroyal (Mentha pulegium), yerba de la perdiz (Margiricarpus pinnatus), oregano (Origanum vulgare), and guaycuri (Statice brasiliensis). Abortion occurred in 23 cases after the ingestion of parsley, ruda, Carachipita, celery, Cedron, francisco alvarez, floripon, espina colorada. Out of the 23 cases, 15 involved the only the ingestion of plants, 4 cases used injected drugs (presumably hormones), and in 4 cases there was associated self-inflicted instrumental manipulation. Multiple organ system failure occurred in those patients who had ingested ruda (alone or in combination with parsley or fennel), Carachipita, arnica, or bardana. Deaths occurred in one case of Carachipita ingestion and in 4 cases of ruda ingestion (2 cases of ruda alone, 2 cases of ruda with parsley and fennel). Self-inflicted instrumental manipulations were found in 4 of the patients with multiple organ system failure and in one of those who died. The results of this report are not conclusive, but it appears that the ingestion of plants to induce abortion involves the risk of severe morbidity and mortality.

    Sunken parcels of macroalgae and wood provide important oases of organic enrichment at the deep-sea floor, yet sediment community structure and succession around these habitat islands are poorly evaluated. We experimentally implanted 100-kg kelp falls and 200 kg wood falls at 1670 m depth in the Santa Cruz Basin to investigate (1) macrofaunal succession and (2) species overlap with nearby whale-fall and cold-seep communities over time scales of 0.25-5.5 yr. The abundance of infaunal macrobenthos was highly elevated after 0.25 and 0.5 yr near kelp parcels with decreased macrofaunal diversity and evenness within 0.5 m of the falls. Apparently opportunistic species (e.g., two new species of cumaceans) and sulfide tolerant microbial grazers (dorvilleid polychaetes) abounded after 0.25-0.5 yr. At wood falls, opportunistic cumaceans become abundant after 0.5 yr, but sulfide tolerant species only became abundant after 1.8-5.5 yr, in accordance with the much slower buildup of porewater sulfides at wood parcels compared with kelp falls. Species diversity decreased significantly over time in sediments adjacent to the wood parcels, most likely due to stress resulting from intense organic loading of nearby sediments (up to 20-30% organic carbon). Dorvilleid and ampharetid polychaetes were among the top-ranked fauna at wood parcels after 3.0-5.5 yr. Sediments around kelp and wood parcels provided low-intensity reducing conditions that sustain a limited chemoautrotrophically-based fauna. As a result, macrobenthic species overlap among kelp, wood, and other chemosynthetic habitats in the deep NE Pacific are primarily restricted to apparently sulfide tolerant species such as dorvilleid polychaetes, opportunistic cumaceans, and juvenile stages of chemosymbiont containing vesicomyid bivalves. We conclude that organically enriched sediments around wood falls may provide important habitat islands for the persistence and evolution of species dependent on organic- and sulfide

    It is essential to guarantee the safety of unprocessed plants and food supplements if consumers' health is to be protected. Although botanicals and their preparations are regulated at EU level, at least in part, there is still considerable discretion at national level, and Member States may choose to classify a product either as a food supplement or as a drug. Accurate data concerning the finished products and the plant used as the starting point are of major importance if risks and safety are to be properly assessed, but in addition standardized criteria for herbal preparation must be laid down and respected by researchers and manufacturers. Physiologically active as well as potentially toxic constituents need to be identified, and suitable analytical methods for their measurement specified, particularly in view of the increasing incidence of economically motivated adulteration of herbal raw materials and extracts. It remains the duty of food operators to keep up with the scientific literature and to provide sufficient information to enable the adaptation of specifications, sampling schemes and analytical methods to a fast-changing environment.

    Recently, the use of herbal medicines has been increased all over the world due to their therapeutic effects and fewer adverse effects as compared to the modern medicines. However, many herbal drugs and herbal extracts despite of their impressive in-vitro findings demonstrates less or negligible in-vivo activity due to their poor lipid solubility or improper molecular size, resulting in poor absorption and hence poor bioavailability. Nowadays with the advancement in the technology, novel drug delivery systems open the door towards the development of enhancing bioavailability of herbal drug delivery systems. For last one decade many novel carriers such as liposomes, microspheres, nanoparticles, transferosomes, ethosomes, lipid based systems etc. have been reported for successful modified delivery of various herbal drugs. Many herbal compounds including quercetin, genistein, naringin, sinomenine, piperine, glycyrrhizin and nitrile glycoside have demonstrated capability to enhance the bioavailability. The objective of this review is to summarize various available novel drug delivery technologies which have been developed for delivery of drugs (herbal), and to achieve better therapeutic response. An attempt has also been made to compile a profile on bioavailability enhancers of herbal origin with the mechanism of action (wherever reported) and studies on improvement in drug bioavailability, exhibited particularly by natural compounds.

    The present study is aimed to diagnose the current public programs focused on herbal medicines in Brazil by means of in loco visits to 10 programs selected by means of questionnaires sent to 124 municipalities that count on herbal medicine services. The main purpose of the implementation of program programs is related to the development of medicinal herbs. 70% of them are intended for the production of herbal medicines and 50% are aimed to ensure the access of the population to medicinal plants and or herbal medicines. The initiative of the implementation of these programs was related to the managers (60%). The difficulties in this implementation were due to the lack of funding (100%) of the programs. In 60% of the programs, the physicians did not adhere to herbal medicine services due to the lack of knowledge of the subject. Training courses were proposed (80%) to increase the adhesion of prescribers to the system. Some municipalities use information obtained from patients to assess the therapeutic efficiency of medicinal plants and herbal medicines. Of the programs underway, cultivation of medicinal plants was observed in 90% and 78% of them adopt quality control. In most programs, this control is not performed in accordance with the legal requirements. The programs focused on medicinal plants and herbal medicines implemented in Brazil face some chronic problems of infrastructure, management, operational capacity and self-sustainability, which can be directly related to the absence of a national policy on medicinal plants and herbal medicines.

Being chemically diverse they are able to modulate several targets simultaneously in a complex system. Analysis of gene expression becomes necessary for better understanding of molecular mechanisms. Conventional strategies for expression profiling are optimized for single gene analysis. DNA microarrays serve as suitable high throughput tool for simultaneous analysis of multiple genes. Major practical applicability of DNA microarrays remains in DNA mutation and polymorphism analysis. This review highlights applications of DNA microarrays in pharmacodynamics, pharmacogenomics, toxicogenomics and quality control of herbal drugs and extracts.

  4. Future climate change is predicted to shift long-term persistence zones in the cold-temperate kelp Laminaria hyperborea.

    2016-02-01

    Global climate change is shifting species distributions worldwide. At rear edges (warmer, low latitude range margins), the consequences of small variations in environmental conditions can be magnified, producing large negative effects on species ranges. A major outcome of shifts in distributions that only recently received attention is the potential to reduce the levels of intra-specific diversity and consequently the global evolutionary and adaptive capacity of species to face novel disturbances. This is particularly important for low dispersal marine species, such as kelps, that generally retain high and unique genetic diversity at rear ranges resulting from long-term persistence, while ranges shifts during climatic glacial/interglacial cycles. Using ecological niche modelling, we (1) infer the major environmental forces shaping the distribution of a cold-temperate kelp, Laminaria hyperborea (Gunnerus) Foslie, and we (2) predict the effect of past climate changes in shaping regions of long-term persistence (i.e., climatic refugia), where this species might hypothetically harbour higher genetic diversity given the absence of bottlenecks and local extinctions over the long term. We further (3) assessed the consequences of future climate for the fate of L. hyperborea using different scenarios of greenhouse gas emissions (RCP 2.6 and RCP 8.5). Results show NW Iberia, SW Ireland and W English Channel, Faroe Islands and S Iceland, as regions where L. hyperborea may have persisted during past climate extremes until present day. All predictions for the future showed expansions to northern territories coupled with the significant loss of suitable habitats at low latitude range margins, where long-term persistence was inferred (e.g., NW Iberia). This pattern was particularly evident in the most agressive scenario of climate change (RCP 8.5), likely driving major biodiversity loss, changes in ecosystem functioning and the impoverishment of the global gene pool of L

    Full Text Available Herbal medicines are the synthesis of therapeutic experiences of generations of practising physicians of indigenous systems of medicine for over hundreds of years while nutraceuticals are nutritionally ormedicinally enhanced foods with health benefits of recent origin and marketed in developed countries. Herbal medicines are also ingreat demand in the developed world for primary health care because of their efficacy, safety and lesser side effects. They also offer therapeutics for age-related disorders like memory loss, osteoporosis, immune disorders, etc. for which no modern medicine is available. WHO too has not systematically evaluated traditional medicines despite the fact that it is used for primary health care by about 80% of the world population. However, in 1991 WHO developed guidelines for the assessment of herbal medicine. Suggestions for herbal medicine standardization are outlined. The scenario and perceptions of herbal medicine are discussed.

    Herbal tea is a commonly consumed beverage brewed from the leaves, flowers, seeds, fruits, stems and roots of plants species rather than Camellia sinensis L., which has been widely used for health care and diseases prevention for centuries. With the increasing consumption of herbal tea, a number of public health issues e.g., efficacy, safety and quality assurance have attracted concern. However, to date, there is no a review focus on herbal tea. Phytochemical analysis, as a key step to investigate the chemical composition of herbal tea and ensure the quality, is very important. In this review, we summarized and discussed the recent development (2005-2012) in phytochemical analysis of herbal tea commonly used in China.

    The project of modernising Western herbal medicine in order to allow it to be accepted by the public and to contribute to contemporary healthcare is now over two decades old. One aspect of this project involves changes to the ways knowledge about medicinal plants is presented. This paper contrasts the models of Evidence-Based Medicine (EBM) and Traditional Knowledge (TK) to illuminate some of the complexities which have arisen consequent to these changes, particularly with regard to the concept of vitalism, the retention or rejection of which may have broad implications for the clinical practice of herbal medicine. Illustrations from two herbals (central texts on the medicinal use of plants) demonstrate the differences between these frameworks in regard to how herbs are understood. Further, a review of articles on herbal therapeutics published in the Australian Journal of Herbal Medicine indicates that practitioners are moving away from TK and towards the use of EBM in their clinical discussions.

    This study was conducted to determine the herbal product use of pregnants as there is not adequate information relating to the rate of herbal product use during pregnancy in Turkey and what is thought about effects and side effects thereof. It is a descriptive study consisted of 366 pregnants admitted to hospital for childbirth in gynaecology and obstetrics clinics of a public hospital or a university hospital. Data were collected with individual information form and question form of herbal product use in pregnancy. We conducted number, percentage, chi-square analyses. It was determined that 47.3% of the women had used at least one herbal product during pregnancy; the relationship between education level, working status, family structure, and status of herbal product use is statistically significant (pginger are the first three herbs used due to common cold-influenza frequently in pregnancy during 1st and 2nd trimesters. More than half of the pregnants stated that they had started herbal product use without any suggestions from anyone, and profoundly low healthcare professional suggestion was detected. Our study has showed that almost half of women use at least one herbal product during pregnancy. So few healthcare professionals give information to pregnants thereabout. Thus, providing information in general health education to pregnant women about benefits and damages of herbal product use, planning researchers on effectiveness of herbal products, assessment of healthcare professionals relating to the matter and provision of available guidelines and in-service education relating to herbal products that can be used during pregnancy may be suggested.

    2012-09-01

    Science, including rigorous basic scientific research and rigorous clinical research, must underlie both the development and the clinical use of herbal medicines. Yet almost none of the hundreds or thousands of articles that are published each year on some aspect of herbal medicines, adheres to 3 simple but profound scientific principles must underlie all of herbal drug development or clinical use. Three fundamental principles that should underlie everyone's thinking about the development and/or clinical use of any herbal medicine. (1) There must be standardization and regulation (rigorously enforced) of the product being studied or being used clinically. (2) There must be scientific proof of a beneficial clinical effect for something of value to the patient and established by rigorous clinical research. (3) There must be scientific proof of safety (acceptable toxicity) for the patient and established by rigorous clinical research. These fundamental principles of science have ramifications for both the scientist and the clinician. It is critically important that both the investigator and the prescriber know exactly what is in the studied or recommended product and how effective and toxic it is. We will find new and useful drugs from natural sources. However, we will have to learn how to study herbal medicines rigorously, and we will have to try to convince the believers in herbal medicines of the wisdom and even the necessity of a rigorous scientific approach to herbal medicine development. Both biomedical science and practicing physicians must enthusiastically accept the responsibility for searching for truth in the discovery and development of new herbal medicines, in the truthful teaching about herbal medicines from a scientific perspective, and in the scientifically proven clinical use of herbal medicines.

    The active components of herbal drugs and substances are pleiotropic multi-ingredient compounds with multitarget properties including antiinflammatory effects. A pleiotropic inhibition of inflammation could play an important role in mutlimorbide patients as an attempt of prevention or retardation of metastasis. A large number of experimental data for European and non-European herbal drugs as well as various herbal drug combinations suggest such a possibility. Despite the so far small number of clinical studies, such an experimental herbal treatment could appear to be reasonable and acceptable, provided that there are data available on quality and safety of these herbal drugs by treatments of patients with various diseases. Besides, herbal drugs and substances play a growing role the treatment of patients with multimorbidity. Many of these herbal drugs have antiinflammatory effects beside their proved symptomatic efficacy in a lot of other diseases. The specific selection of herbal drugs that are efficacious in specific indications and additionally showed antiinflammatory effects offers the possibility of simultaneous antiinflammatory and specific efficacy. St. John's Wort and milk thistle belong to the oldest and to the best experimentally and clinically examined herbal remedies. The spectrum of internal and external uses of Hypercum perforatum as a multicompound herbal drug includes functional gastro-intestinal complaint and illness, skin disease, mucosal lesion, superficial injury, depressive upset and depression, somatoform disorders, restlessness, nervosity, convalescence, exhaustion and sleep disturbances respectively. The plurivalent character of the multicompound even enables a broad spectrum of activity. This might justify to prefer St. John's Wort to other drugs in a wide range of treatments: In multimorbide patients with depression or in depressive patients with coronary heart disease the anti-inflammatory effects could mean an additional advantage

    Full Text Available Globally, people are struggling with obesity. Many effective, non-conventional methods of weight reduction, such as herbal and natural dietary supplements, are increasingly being sought. Fat burners are believed to raise metabolism, burn more calories and hasten fat loss. Despite patient perceptions that herbal remedies are free of adverse effects, some supplements are associated with severe hepatotoxicity. The present report describes a young healthy woman who presented with fulminant hepatic failure requiring emergent liver transplantation caused by a dietary supplement and fat burner containing usnic acid, green tea and guggul tree extracts. Thorough investigation, including histopathological examination, revealed no other cause of hepatotoxicity. The present case adds to the increasing number of reports of hepatotoxicity associated with dietary supplements containing usnic acid, and highlights that herbal extracts from green tea or guggul tree may not be free of adverse effects. Until these products are more closely regulated and their advertising better scrutinized, physicians and patients should become more familiar with herbal products that are commonly used as weight loss supplements and recognize those that are potentially harmful.

    Full Text Available Most of the metabolic and physiological processes of our body as well as the detoxification of various drugs and xenobiotic chemicals occur in the liver. During this detoxification process, the reactive chemical intermediates damage the liver severely. There are several commercially available drugs, consumption of which results in idiosyncratic drug reaction mediated hepatotoxicity. Drug induced hepatotoxicity is a burning problem in this regard and several drugs are withdrawn from the market due to their hepatotoxic nature. Today, worldwide search of non-hepatotoxic drugs, especially potent hepatoprotective drugs have led towards the screening of numerous herbal products. Pharmaceutical companies and scientific communities have started to consider the therapeutic efficiency of the plant-based hepatoprotective remedies. Different herbs are mentioned in various ethnopharmacological practices possessing hepatoprotective capacities and around the globe, such herbs are still used by people to cure certain liver diseases. Therefore, we have documented the various aspects of hepatotoxicity and an overview on the current scenario of the hepatoprotective herbal remedies.

    Full Text Available Herbal therapy is a holistic therapy, integrating emotional, mental and spiritual levels. Life style, emotional, mental and spiritual considerations are part of any naturopathic approach. The use of herbs does not generally involve "drug" actions or adverse effects. Although medicinal plants are widely used and assumed to be safe, however, they can potentially be toxic. Where poisoning from medicinal plants has been reported, it usually has been due to misidentification of the plants in the form, in which they are sold, or incorrectly preparation and administration by inadequately trained personnel. There are some "drug like" plants remedies that their actions approach that of pharmaceuticals. Herbalists use these plants in treatment strategies and in countries such as Britain their vast availability is restricted by law. Digitalis is one of these examples and the number of these plants is not a lot. The mechanisms by which the herbs generally act are not established, however, most of medicinal plants possess antioxidant activities. The plants have been shown to effective by this property is various conditions including cancer, memory deficit and Alzheimer, atherosclerosis, diabetes and other cardiovascular diseases. Antioxidant activities of herbal medicines are also effective in reducing the toxicities of toxic agents or other drugs.

    Herbal tea consumption is deeply and widely rooted amongst South-American populations. In view of the involvement of oxygen- and nitrogen-reactive species in the ethiogenesis of several diseases, the antioxidant properties of some of the herbal teas most commonly consumed in the southern regions was assessed in vitro. Around one-third of the 13 examined herbs, displayed a substantially higher ability to scavenge ABTS(+.) radicals (TEAC assay), and to quench the pro-oxidant species, hypochlorite (HClO) and peroxynitrite (ONOO(-)). Amongst the tested herbs, teas prepared from Haplopappus baylahuen, Rosa moschata and Peumus boldus showed the highest TEAC and HClO-quenching activities. These herbs were around 5- to 7-fold more potent than the least active herbs. Based on the TEAC assay, 150 mL of tea prepared from H. baylahuen, R. moschata and P. boldus would be equivalent to around 200 mg of Trolox). Teas from H. baylahuen and P. boldus were also found to be particularly potent in quenching HClO. In the ONOO(-) assay, H. baylahuen and Buddleia globosa showed the highest activities. The results obtained suggest that the regular consumption of teas prepared from some of these herbs may be useful potentially to provide the organism with molecules capable of protecting the gastrointestinal tract against certain pathologically relevant oxidant species.

    Phlorotannins of brown algae are multifunctional compounds with putative roles in herbivore deterrence, antioxidation and as primary cell wall components. Due to their peripheral localization and absorption at short wavelengths, a photoprotective role is suggested. We examined the induction of phlorotannins by artificial UV radiation in the intertidal kelp Lessonia nigrescens and whether they attenuate the inhibition of photosynthesis and DNA damage, two major detrimental effects of UV. The soluble and cell wall-bound fractions of phlorotannins were quantified in blades collected in summer and winter. Major findings were that (1) the synthesis of phlorotannins (both forms) was induced by UV only in summer; (2) the induction was fast (within 3 days); and (3) there was a positive relationship between of the contents of insoluble phlorotannins and the suppression of photoinhibition and DNA damage, measured as formation of cyclobutane pyrimidine dimers and 6-4 photoproducts. Overall, the photoprotective role of phlorotannins appears to respond to an interplay between the external UV stimulus, seasonal acclimation and intrinsic morpho-functional processes. In summer, when algae are naturally exposed to high UV irradiances, soluble phlorotannins are induced, while their transition to insoluble phlorotannins could be related with the growth requirements, as active blade elongation occurs during this season.

    Full Text Available Abstract Background Women aged ≥ 65 years are high utilizers of prescription and over-the-counter medications, and many of these women are also taking dietary supplements. Dietary supplement use by older women is a concern because of possible side effects and drug-supplement interactions. The primary aim of this study was to provide a comprehensive picture of dietary supplement use among older women in a large health plan in Northern California, USA, to raise awareness among health care providers and pharmacists about the need for implementing structural and educational interventions to minimize adverse consequences of self-directed supplement use. A secondary aim was to raise awareness about how the focus on use of herbals and megavitamins that has occurred in most surveys of complementary and alternative therapy use results in a significant underestimate of the proportion of older women who are using all types of dietary supplements for the same purposes. Methods We used data about use of different vitamin/mineral (VM supplements and nonvitamin, nonmineral (NVNM supplements, including herbals, from a 1999 general health survey mailed to a random sample of adult members of a large Northern California health plan to estimate prevalence of and characteristics associated with supplement use among women aged 65–84 (n = 3,109. Results Based on weighted data, 84% had in the past 12 months used >1 dietary supplement, 82% a VM, 59% a supplement other than just multivitamin or calcium, 32% an NVNM, and 25% an herbal. Compared to white, nonHispanic women, African-Americans and Latinas were significantly less likely to use VM and NVNM supplements and Asian/Pacific Islanders were less likely to use NVNM supplements. Higher education was strongly associated with use of an NVNM supplement. Prevalence did not differ by number of prescription medications taken. Among white, nonHispanic women, multiple logistic regression models showed that college

    Full Text Available Herbal medicines have played an important role in treating different diseases since ancient times. Bioactive components of medicinal plants are a good starting point for discovering new drugs such as chemotherapeutics. Currently, there are four classes of plant-derived chemotherapeutic drugs used in clinical practice. However, to discover new potential cytotoxic molecules, the research effort on herbal extracts has not diminished. The aim of this review was to evaluate the chemical constituents of plants that possess cytotoxicity, the signalling pathways responsible for this effect, and the influence of solvent polarity on potential cytotoxic effect and to present the cytotoxic activity of selected herbal extracts. The polyphenolic, anthraquinon, diterpneoid, triterpenoid, flavonoid, betulinic acid and berberine content contributes to cytotoxicity of herbal extracts. The inhibitory effect on cancer cells viability could be a consequence of the non-apoptotic processes, such as cell cycle arrestment, and the apoptotic process in tumour cells through different signalling pathways. The influence of solvent polarity on potential cytotoxic effect of herbal extracts should not be ignored. In general, the best cytotoxic activity was found in nonpolar and moderately polar herbal extracts. The herbal extract with IC50 below 30 μg/ml could be considered a very strong cytotoxic agent. Considering that many antitumor drugs have been discovered from natural products, further research on plants and plant-derived chemicals may result in the discovery of potent anticancer agents.

    The global economy of the international trade of herbal products has been increasing by 15% annually, with the raw material for most herbal products being sourced from South and Southeast Asian countries. In India, of the 8000 species of medicinal plants harvested from the wild, approximately 960 are in the active trade. With increasing international trade in herbal medicinal products, there is also increasing concern about the widespread adulteration and species admixtures in the raw herbal trade. The adverse consequences of such species adulteration on the health and safety of consumers have only recently begun to be recognised and documented. We provide a comprehensive review of the nature and magnitude of species adulteration in the raw herbal trade, and identify the underlying drivers that might lead to such adulteration. We also discuss the possible biological and chemical equivalence of species that are used as adulterants and substitutes, and the consequences thereof to consumer health and safety, and propose a framework for the development of a herbal trade authentication service that can help regulate the herbal trade market.

    Novel drug delivery system is a novel approach to drug delivery that addresses the limitations of the traditional drug delivery systems. Our country has a vast knowledge base of Ayurveda whose potential is only being realized in the recent years. However, the drug delivery system used for administering the herbal medicine to the patient is traditional and out-of-date, resulting in reduced efficacy of the drug. If the novel drug delivery technology is applied in herbal medicine, it may help in increasing the efficacy and reducing the side effects of various herbal compounds and herbs. This is the basic idea behind incorporating novel method of drug delivery in herbal medicines. Thus it is important to integrate novel drug delivery system and Indian Ayurvedic medicines to combat more serious diseases. For a long time herbal medicines were not considered for development as novel formulations owing to lack of scientific justification and processing difficulties, such as standardization, extraction and identification of individual drug components in complex polyherbal systems. However, modern phytopharmaceutical research can solve the scientific needs (such as determination of pharmacokinetics, mechanism of action, site of action, accurate dose required etc.) of herbal medicines to be incorporated in novel drug delivery system, such as nanoparticles, microemulsions, matrix systems, solid dispersions, liposomes, solid lipid nanoparticles and so on. This article summarizes various drug delivery technologies, which can be used for herbal actives together with some examples.

    Full Text Available World Health Organization (WHO has defined herbal medicines as finished labeled medicinal product that contain an active ingredient, aerial, or underground parts of the plant or other plant material or combinations. According to a report of WHO, about 80% of the world population is reported to rely on traditional medicine for their primary health care needs. Even in the developed countries, complementary or alternative medicine is gaining popularity. A report of a global survey on national policy on traditional medicine and regulation of herbal medicines indicated that about 50 countries including China, Japan, and Germany already have their national policy and laws on regulations of traditional medicines. Herbal drugs possess a long history of its use and better patient tolerance. These are cheaper and easily available in countries like India due to rich agro culture conditions. However, reckless utilization of resources threatens the sustainability of several plant species. Traditional medicines are governed by the Drugs and Cosmetics Act of 1940 and the Drugs and Cosmetics Rules of 1945. In 1959, the Government of India amended the Drugs and Cosmetics Act to include drugs that are derived from traditional Indian medicine. In 1993, the guidelines for the safety and efficacy of herbal medicines developed by an expert committee directed that the procedures laid down by the office of the Drug Controller General of India for allopathic drugs should be followed for all traditional and herbal products to enter into clinical trials for any therapeutic condition. However, there are certain loop holes in the clinical trials of herbal drugs as the lack of stringent bylaws and regulations. Hence, a deep insight of important challenges and major regulatory guidelines for clinical trial of herbal drugs and botanicals is discussed in the present communication.

    Autism is a comprehensive growth abnormality in which social skills, language, communication, and behavioral skills are developed with delay and as diversionary. The reasons for autism are unclear, but various theories of genetics, immunity, biological, and psychosocial factors have been proffered. In fact, autism is a complex disorder with distinct causes that usually co-occur. Although no medicine has been recognized to treat this disorder, pharmacological treatments can be effective in reducing its signs, such as self-mutilation, aggression, repetitive and stereotyped behaviors, inattention, hyperactivity, and sleeping disorders. Recently, complementary and alternative approaches have been considered to treat autism. Ginkgo biloba is one of the most effective plants with an old history of applications in neuropsychological disorders which recently is used for autism. The present review discusses the recent findings, pathophysiology, and etiology of autism and thereafter addresses the promising results of herbal remedies.

    Reproducibility is an important issue in biological characterization of drug candidates and natural products. It is not uncommon to encounter cases in which supposedly the same sample exhibits very different biological activities. During our characterization of macrophage-stimulatory lipids from herbal medicine, it was found that the potency of these lipids could vary substantially from experiment to experiment. Further analysis of this reproducibility issue led to the discovery of solvent-dependent nanoparticle formation by these lipids. While larger nanoparticles (approximately 100 nm) of these lipids showed modest macrophage-stimulatory activity, smaller nanoparticles (nanoparticle formation and macrophage-stimulatory activity of plant lipids. Although nanoparticles have been extensively studied in the context of vehicles for drug delivery, our finding indicates that drugs themselves can form nanoassemblies, and their biological properties may be altered by the way they assemble. © 2013 John Wiley & Sons A/S.

    Full Text Available Galactogogues elicit pharmacological effects, resulting in increased prolactin concentration through interactions with dopamine receptors and thereby augmenting milk supply. Commercially available synthetic drugs induce adverse effect on the neuro-endocrine axis of lactation physiology. Their prolonged uses have caused toxicity which opens a detrimental platform to normal health status of both human and animals. So the researchers have developed a keen interest in traditional herbs, because these are easily available, cheap and with a hope that they may not leave any toxic residues in milk. Phyto-pharmacological research on natural products can contribute for the discovery of new active compounds with novel structures which may serve as a lead for the development of new galactogogues. Although majority of these herbal preparations have not been evaluated their traditional use suggests that they are safe and effective. The purpose of this review paper was to succinctly review recent progress made in the field of commercially available and tranditional galactogogues.

Acharyas described krimis in various Samhitas in detail and they also believed that krimi also act as an etiological factor in various disease e.g. krimija shiorroga, hridaroga etc. Because of the fewer side effects, the importance of herbal drugs in remedy has tremendously increased in the recent years. A wide variety of plants possess narrow or broad spectrum anthelminthic activities which are naturally available.

    Chinese herbal medicine is a promising countermeasure against cardiovascular dysfunction associated with a sedentary lifestyle. We examined the impact of the Chinese herb, Taikong Yangxin, on the micro- and macrovascular dysfunction associated with a 60-day bed rest. Fourteen healthy men were randomly divided into two groups: those given herbal supplement, and the control group; the two groups underwent a 60-day bed rest. The macrovasculature was assessed by sonography. Skin microvascular functions were assessed with laser Doppler. The plasma level of endothelial microparticles (EMPs), markers of endothelial injury, was determined. Bed rest induced a 33 % decrease in the femoral artery diameter and compliance whereas carotid wall thickness, diameter, and compliance remained unchanged. The early phase of endothelium-dependent vasodilation to ACh was unmodified by bed rest, while the late phase was reduced by 30 % along with a twofold increase in EMPs. In those given Taikong Yangxin, the early phase was amplified by 2.5-fold, and the effects of bed rest on the late phase were prevented. These findings indicate that Taikong Yangxin ameliorates endothelium-dependent vasodilation, likely by improving the NO pathway. The study suggests Taikong Yangxin as a new countermeasure to prevent the changes in microvascular function induced by physical inactivity.

    Complications of type 2 diabetes (T2D) include stroke, which is a cerebrovascular disturbance characterized by reduced blood flow in the brain, leading to death or physical disability. Chinese herbal medicine (CHM) has been widely used in ancient China for the treatment of diabetes and stroke by supplementing Qi and activating blood circulation. This study aimed to investigate the frequencies and patterns of CHM treatment for stroke patients with T2D and the outcomes of long-term use in Taiwan. We identified 3079 stroke patients (ICD-9-CM: 430-438) with T2D. We allocated 618 stroke patients, matched for age, gender, and T2D-to-stroke duration, to both CHM and non-CHM groups. Chi-square test, conditional multivariable logistic regression, Kaplan-Meier method, and the log-rank test were used in this study. The CHM group was characterized by more cases of chronic obstructive pulmonary disease, ulcer disease, hyperlipidemia, tobacco use, and higher income. The cumulative survival probability was higher in the CHM group (Pherbs, respectively. The use of CHM as adjunctive therapy may improve the overall survival (OS) of stroke patients with T2D. The list of the comprehensive herbal medicines that they used might be useful in future large-scale, randomized clinical investigations of agent effectiveness, safety, and potential interactions with conventional treatments in stroke patients with T2D.

    Full Text Available In Italy most herbal products are sold as food supplements and are subject only to food law. A list of about 1200 plants authorised for use in food supplements has been compiled by the Italian ministry of Health. In order to review and possibly improve the ministry's list an ad hoc working group of Istituto Superiore di Sanità was requested to provide a technical and scientific opinion on plant safety. The listed plants were evaluated on the basis of their use in food, therapeutic activity, human toxicity and in no-alimentary fields. Toxicity was also assessed and plant limitations to use in food supplements were defined.

    Full Text Available Objective. To review the literature on fat modifying dietary supplements commonly used for weight loss. Methods. Recently published randomized, placebo-controlled trials were identified in PubMed, MEDLINE, International Pharmaceutical Abstracts, Cochrane Database, and Google Scholar using the search terms dietary supplement, herbal, weight loss, obesity, and individual supplement names. Discussion. Data for conjugated linoleic acid (CLA, Garcinia cambogia, chitosan, pyruvate, Irvingia gabonensis, and chia seed for weight loss were identified. CLA, chitosan, pyruvate, and Irvingia gabonensis appeared to be effective in weight loss via fat modifying mechanisms. However, the data on the use of these products is limited. Conclusion. Many obese people use dietary supplements for weight loss. To date, there is little clinical evidence to support their use. More data is necessary to determine the efficacy and safety of these supplements. Healthcare providers should assist patients in weighing the risks and benefits of dietary supplement use for weight loss.

    Diabetes mellitus is the most common endocrine disorder, affecting 16 million individuals in the United States and 200 million worldwide. Despite the use of advanced synthetic drugs for the treatment, use of herbal remedies is gaining higher importance because of synthetic drugs have drawbacks and limitations. The herbal drugs with antidiabetic activity are extensively formulated commercially because of easy availability, affordability and less side effects as compared to the synthetic antidiabetic drugs. Antidiabetic herbal formulations (AHF) are considered to be more effective for the management of diabetes. There are around 600 herbal drug manufacturers in India of which almost all manufacturers are developing AHF in addition to others. Till date, no article is published to give detailed information of the patents on AHF. Thus, this review article undertake the attempt for providing updated information on the type of diabetes and patented AHF which will enhance the existing knowledge of the researchers.

  14. Commonly Used Dietary Supplements on Coagulation Function during Surgery

    Directory of Open Access Journals (Sweden)

    Chong-Zhi Wang

    2015-07-01

    Full Text Available Background: Patients who undergo surgery appear to use dietary supplements significantly more frequently than the general population. Because they contain pharmacologically active compounds, dietary supplements may affect coagulation and platelet function during the perioperative period through direct effects, pharmacodynamic interactions, and pharmacokinetic interactions. However, in this regard, limited studies have been conducted that address the pharmacological interactions of dietary supplements. To avoid possible bleeding risks during surgery, information about the potential complications of dietary supplements during perioperative management is important for physicians. Methods: Through a systematic database search of all available years, articles were identified in this review if they included dietary supplements and coagulation/platelet function, while special attention was paid to studies published after 1990. Results: Safety concerns are reported in commercially available dietary supplements. Effects of the most commonly used natural products on blood coagulation and platelet function are systematically reviewed, including 11 herbal medicines (echinacea, ephedra, garlic, ginger, ginkgo, ginseng, green tea, kava, saw palmetto, St John’s wort, and valerian and four other dietary supplements (coenzyme Q10, glucosamine and chondroitin sulfate, fish oil, and vitamins. Bleeding risks of garlic, ginkgo, ginseng, green tea, saw palmetto, St John’s wort, and fish oil are reported. Cardiovascular instability was observed with ephedra, ginseng, and kava. Pharmacodynamic and pharmacokinetic interactions between dietary supplements and drugs used in the perioperative period are discussed. Conclusions: To prevent potential problems associated with the use of dietary supplements, physicians should be familiar with the perioperative effects of commonly used dietary supplements. Since the effects of dietary supplements on coagulation and platelet

    Studies of thermal tolerance in marine ectotherms are key in understanding climate effects on ecosystems; however, tolerance of their larval stages has rarely been analyzed. Larval stages are expected to be particularly sensitive. Thermal stress may affect their potential for dispersal and zoogeographical distribution. A mismatch between oxygen demand and the limited capacity of oxygen supply to tissues has been hypothesized to be the first mechanism restricting survival at thermal extremes. Therefore, thermal tolerance of stage zoea I larvae was examined in two populations of the Chilean kelp crab Taliepus dentatus, which are separated by latitude and the thermal regime. We measured temperature-dependent activity, oxygen consumption, cardiac performance, body mass and the carbon (C) and nitrogen (N) composition in order to: (1) examine thermal effects from organismal to cellular levels, and (2) compare the thermal tolerance of larvae from two environmental temperature regimes. We found that larval performance is affected at thermal extremes indicated by decreases in activity, mainly in maxilliped beat rates, followed by decreases in oxygen consumption rates. Cardiac stroke volume was almost temperature-independent. Through changes in heart rate, cardiac output supported oxygen demand within the thermal window whereas at low and high temperature extremes heart rate declined. The comparison between southern and central populations suggests the adaptation of southern larvae to a colder temperature regime, with higher cardiac outputs due to increased cardiac stroke volumes, larger body sizes but similar body composition as indicated by similar C:N ratios. This limited but clear differentiation of thermal windows between populations allows the species to widen its biogeographical range.

    Background:The use of antibiotics in animal diets is facing negative feedback due to the hidden danger of drug residues to human health. Traditional Chinese herbal medicine has been used to replace antibiotics in the past two decades and played an increasingly important role in livestock production. The present study was carried out to assess the feeding effects of a traditional nourishing Chinese herbal medicine mixture on kinetics of plasma glucose, protein and energy metabolism in sheep. Ruminal fermentation characteristics were also determined. Methods:Four sheep were fed on either mixed hay (MH-diet) or MH-diet supplemented with 2%of Chinese herbal medicine (mixture of Astragalus root, Angelica root and Atractylodes rhizome;CHM-diet) over two 35-day periods using a crossover design. The turnover rate of plasma glucose was measured with an isotope dilution method using [U-13C]glucose. The rates of plasma leucine turnover and leucine oxidation, whole body protein synthesis (WBPS) and metabolic heat production were measured using the [1-13C]leucine dilution and open circuit calorimetry. Results:Body weight gain of sheep was higher (P=0.03) for CHM-diet than for MH-diet. Rumen pH was lower (P=0.02), concentration of rumen total volatile fatty acid tended to be higher (P=0.05) and acetate was higher (P=0.04) for CHM-diet than for MH-diet. Turnover rates of plasma glucose and leucine did not differ between diets. Oxidation rate of leucine tended to be higher (P=0.06) for CHM-diet than for MH-diet, but the WBPS did not differ between diets. Metabolic heat production tended to be greater (P=0.05) for CHM-diet than for MH-diet. Conclusions:The sheep fed on CHM-diet had a higher body weight gain and showed positive impacts on rumen fermentation and energy metabolism without resulting in any adverse response. Therefore, these results suggested that the Chinese herbal medicine mixture should be considered as a potential feed additive for sheep.

Our country has a vast knowledge base of Ayurveda whose potential is only being realized in the recent years. However, the drug delivery system used for administering the herbal medicine to the patient is traditional and out-of-date, resulting in reduced efficacy of the drug. If the novel drug delivery technology is applied in herbal medicine, it may help in...

    Full Text Available Acute kidney injury (AKI is a major health threat worldwide. The literature on herbal intervention in AKI was searched from English and Chinese databases and reports were critically analyzed in terms of preventing AKI, promoting repair and regeneration, enhancing extrarenal clearance of uremic toxins, and preventing progression to chronic kidney disease (CKD. Altogether, 16 herbal formulae and a few extracts derived from individual herbs were reported to prevent or mitigate AKI in animal models induced by renal ischemia/reperfusion, cisplastin, gentamicin, glycerol, adenine, sepsis or physical exhaustion. Four formulae and six individual herbs were reported to accelerate recovery and/or to prevent CKD in established AKI animal models. Intrarectal herbal medicines, with or without simultaneous oral administration, were reported in six clinical trials and in an animal model to increase extrarenal clearance of uremic toxins. Additional 13 clinical trials reported oral or intravenous herbal interventions in AKI of different etiologies. Despite recurring problems, notably poor compliance with good practice guidelines for clinical trials and for authentication, naming and quality control of herbal materials, accumulating experimental data on the preventive effects of herbal medicines in AKI look encouraging and urge for better, definitive trials to guide clinical practice. Herbal enemas promoting extrarenal clearance of uremic toxins seem cost-effective, but better clinical evidence is certainly needed before any affirmative recommendation be made for AKI patients without access to dialysis. New frontiers, however, lie in those herbal remedies that promote repair/regeneration and prevent chronicity after AKI. Recent experimental data suggest that this may be possible.

    Full Text Available Background: Following the Alma-Ata Declaration of 1978, the World Health Organization (WHO began the issuance of guidelines for developing standardized herbal preparations from Traditional Medicine (TM. Similarly in 1987, the International Organization for Standardization (ISO launched the most anticipated industrial standard (ISO 9001 in world history. The seventh (7th clause of ISO 9001’s eight clauses is devoted to “Product Realization”- a quality management system (QMS procedure that includes: planning of product realization; appreciation of customer-related processes; design and development processes; purchasing; production and service provision; and control of measuring and monitoring equipment. Purpose: The article takes a hard look at the QMS processes involved in product realization and the critical stages of the WHO model of herbal drug development from TM, with a view to devising a framework that can be used to promote the production of quality herbal products, commencing from the stage of ethnobotanical survey, through the laboratory, to the clinic.Methodology: Both the WHO model of herbal drug development and the 7th clause of ISO 9001:2008 were critically reviewed and combined to yield a framework that is discussed within the context of guiding herbal drug development from TM. Results and Discussion: The resulting WHO-ISO framework of herbal product realization is discussed in terms of its relevance to practical problems of GMP-production using herbal starting materials, given their innate variability in composition, potency and appearance. Conclusion: The provisions of ISO 9001’s seventh clause can, to a large extent, be applied to the production of quality herbal products developed in accordance with WHO.

    In Mexico, local empirical knowledge about medicinal properties of plants is the basis for their use as home remedies. It is generally accepted by many people in Mexico and elsewhere in the world that beneficial medicinal effects can be obtained by ingesting plant products. In this review, we focus on the potential pharmacologic bases for herbal plant efficacy, but we also raise concerns about the safety of these agents, which have not been fully assessed. Although numerous randomized clinical trials of herbal medicines have been published and systematic reviews and meta-analyses of these studies are available, generalizations about the efficacy and safety of herbal medicines are clearly not possible. Recent publications have also highlighted the unintended consequences of herbal product use, including morbidity and mortality. It has been found that many phytochemicals have pharmacokinetic or pharmacodynamic interactions with drugs. The present review is limited to some herbal medicines that are native or cultivated in Mexico and that have significant use. We discuss the cultural uses, phytochemistry, pharmacological, and toxicological properties of the following plant species: nopal (Opuntia ficus), peppermint (Mentha piperita), chaparral (Larrea divaricata), dandlion (Taraxacum officinale), mullein (Verbascum densiflorum), chamomile (Matricaria recutita), nettle or stinging nettle (Urtica dioica), passionflower (Passiflora incarnata), linden flower (Tilia europea), and aloe (Aloe vera). We conclude that our knowledge of the therapeutic benefits and risks of some herbal medicines used in Mexico is still limited and efforts to elucidate them should be intensified.

    In accord with the notions of humoralism that prevailed in medieval medicine, therapeutic interventions, including diuretics, were used to restore the disturbed balance among the four humors of the human body: blood, phlegm, yellow bile, and black bile. Most diuretics were derived from plants. The primary textual reference on herbal diuretics was Dioscorides's De Materia Medica, which was written during the first century CE. The authors reviewed the medieval medical texts written in Persian and Arabic and compiled a list of 135 herbal diuretics used by the medieval medical authorities for treating various ailments. Between the 8th and 11th centuries CE, Middle Eastern physicians systematically reviewed extant books on medicine and pharmacotherapy and compiled new and expanded lists of herbal medicines, diuretics in particular. Furthermore, they introduced new chemical methods of extraction, distillation, and compounding in the use of herbal medicines. Several herbal remedies now are considered as potentially safe and affordable alternatives to chemical pharmaceuticals. Thus, research on medieval herbal therapies may prove to be relevant to the practice of current cardiovascular and renal pharmacotherapy. The authors propose that modern research methods can be employed to determine which of these agents actually are effective as diuretics.

    Dentinal hypersensitivity (DH) is a common painful condition of the teeth of adults. The present study was conducted to assess and compare the efficacy of a commercially-available novel herbal dentifrice with a non-herbal potassium nitrate in the reduction of DH. A total of 145 individuals (73 males and 72 females; aged 25-60 years) were divided into three groups randomly: (a) group 1: a placebo dentifrice; (b) group 2: a commercially-available herbal dentifrice; and (c) group 3: 5% non-herbal potassium nitrate. The sensitivity scores for controlled air stimulus and cold water were recorded at baseline, 6 weeks, and 12 weeks. Both groups 2 and 3 were found to be significantly better, as compared to the placebo group at the end of 6 and 12 weeks in the reduction of DH. Group 2 also showed comparable results in the reduction of DH when compared to group 3. The herbal dentifrice showed comparable results to the non-herbal dentifrice and can be recommended for the treatment of DH. © 2014 Wiley Publishing Asia Pty Ltd.

    This paper deals with the current regulatory and legal settings of traditional plant food supplements and herbal medicinal products in the European Union (EU). Marketing of botanicals in foods and food supplements in the EU is subject to several provisions of food law, which cover aspects of safety, production, labelling and product composition, including the use of additives and maximum levels of contaminants and residues. However, due to limited harmonization at the EU level, specific national regulations adopted at a Member State level also apply and mutual recognition is the mechanism through which such products can be marketed in EU countries other than those of origin. Unlike food supplements, marketing of traditional herbal medicinal products is regulated by an ad hoc Directive (i.e. Directive 2004/24/EC) covering in detail all the relevant aspects of these products, including a facilitated registration procedure at national level. However, by distinguishing traditional herbal medicinal products from plant food supplements and establishing selective marketing modalities for these two product categories, the EU has been confronted with implementation difficulties for traditional herbal medicinal products and a lack of homogeneity in the regulatory approaches adopted in different EU Member States. In fact, currently the nature of the commercial botanical products made available to consumers as traditional medicinal products or food supplements, depends largely on the EU Member State under consideration as a consequence of how competent National Authorities and manufacturing companies interpret and apply current regulations rather than on the intrinsic properties of the botanical products and their constituents. When the EU approach is compared with approaches adopted in some non-European countries to regulate these product categories, major differences become evident.

    Full Text Available Systematic search of bibliographic databases was conducted to describe the prevalence of dietary supplement use in cardiac patients. Included for review were studies that investigated supplement use in people with cardiovascular risk factors or proven cardiovascular disease. Databases searched were Medline, EMBASE, CINAHL, AMED, Meditext, H&S and IPA. Over five hundred articles were retrieved and twenty studies met the criteria for this review. Dietary supplements were taken by a median 36% (interquartile range: 26–42% of cardiac patients; 36% (IQR 18–43% reported taking a vitamin/mineral supplement and 12% (IQR 7–21% used herbal supplements. Many users indicated that supplements were taken specifically for heart health and 16–64% of users reported using supplements alongside prescription medications. However 39–95% of treating physicians were unaware of patients’ supplement use. Dietary supplement use in patients with cardiovascular disease appears common, as does the concurrent use of supplements with prescription medicines. This information is often not communicated to doctors and treating physicians may need to be more proactive in asking about supplement use.

    Full Text Available Nanophytomedicines are prepared from active phytoconstituents or standardized extracts. The world market for nanomedicine is estimated to reach $130.9 billion by the fiscal year 2016. Liposome nanoparticle (NP with entrapped doxorubicin has been reported to be 300 fold more effective because of better pharmacokinetic ability in treatment of Kaposi sarcoma. NP of paclitaxel is used in the treatment of breast cancer. It has increased water solubility, reduced toxicity and improved therapeutic index. Nanotized herbal drug containing active principles of veteh root, seawort, cassia twig and liquorice root is found to be effective in pulmonary, liver, bone, brain and skin cancer. The in-vivo pharmacokinetic parameters of polymeric nanoparticles containing curcumin reveal at least 9 fold increase in oral bioavailability when compared to curcumin administered with piperine as absorption enhancer. The green nanotechnology utilizes plant based phytochemicals in the overall synthesis and architecture of NP. Cumin and gum arabic are used for synthesis of gold NP that has reduced toxicity to living organism and environment. Bhasma used in Ayurveda is ancient but ultra modern nanomedicine prepared from metal. Swarna bhasma has particle size of 56 nm. NP in cosmetics has been used safely and effectively. NP ingredients like Zno and TiO2 have properties that provide greater degree of protection from sun. Liposome containing Aloe vera extract in size range less than 200 nm diameter has shown higher rate of cell proliferation and increased synthesis of collagenase in in vitro test using human skin fibroblast and epidermal keratinocytes.

    This work demonstrates the phytotoxicity screening of composted herbal pharmaceutical industry waste (HPIW) using seed bioassay method. The composted industrial waste should be tested at lab scale prior to recommendation for land application. HPIW was mixed with soil to produce four treatments: T(1) (1:1), T(2) (1:2), T(3) (1:3), and T(4) (1:0) for toxicity screening using Pisum sativum seeds. After 72 h relative seed germination (RSG), relative root growth (RRG) and germination index (GI) were recorded. Seedlings were observed for further plant growth and tissue biochemistry (chlorophyll, soluble sugar, starch, carotenoid, and protein) estimation. RSG, RRG, and GI values were better in T(1) and T(2) than others. GI was in the ranges of 36.62 % (T(4)) to 170.38 % (T(2)). The seedling growth and biochemical parameters were better in seedling obtained from potting media containing low proportion of HPIW (i.e., T(1) and T(2)). Results clearly suggested that composted HPIW may be utilized effectively for crop production after dilution under sustainable farming system program.

    The present study aims to investigate the effect of some herbal extract such as phenolic compounds on the viability of Leishmania tropica promastigotes in vitro. Four tested chemical agents (caffeic acid (CA), ferulic acid (FA), syringic acid (SA) and 4-hydroxybenzoic acid (4-HBA)) were used in this study. The viability of Leishmania tropica promastigotes was investigated under five different concentrations (10, 15, 20, 25 and 30 mg/ml) of each agent after (72 h). CA was the most active agent on the promastigotes viability after 72 h exposure to 30 mg/ml concentration so that the parasiticidal effect reach (53 × 10(4)) promastigote/ml. FA is the second agent in parasiticidal effect that parasiticidal effect reach to (50 × 10(4) promastigote/ml) at a concentration (30 mg/ml), 4-HBA is the third agent in parasiticidal effect that reach to (48 × 10(4) promastigote/ml) at a concentration (30 mg/ml), SA is the weakest agent in parasiticidal activity that reach to (44 × 10(4) promastigote/ml) at a concentration (30 mg/ml). It can be concluded that (CA, FA, SA and 4-HBA) possess acidal effect on the Leishmania tropica promastigotes in vitro.

    1997-11-01

    Since 1991, the Medical Toxicology Unit (MTU) at Guys' Hospital, London, has been assessing the toxicological problems associated with the use of traditional and herbal remedies and dietary supplements. This assessment was carried out by evaluating reports to the National Poisons Information Service (London) [NPIS(L)] which provides emergency information to medical professionals. Relevant telephone enquiries to NPIS(L) were identified. Further case details were obtained by follow-up questionnaire, clinical consultation, toxicological analysis of samples from patients and/or products and botanical identification of plant material. Of 1297 symptomatic enquiries evaluated there was a possible/confirmed association in 785 cases. Case series have been identified which substantiate previous reports, including liver problems following the use of Chinese herbal medicine for skin disorders, allergic reactions to royal jelly and propolis and heavy metal poisoning caused by remedies from the Indian subcontinent. Although the overall risk to public health appears to be low, certain groups of traditional remedies have been associated with a number of potentially serious adverse effects. Considering the extent of use of herbal remedies and food supplements a comprehensive surveillance system for monitoring the adverse health effects of these products is essential. Surveillance of a large population is needed for the complex task of identifying the uncommon and unpredictable adverse effects which are potentially serious. In the UK, the Medicines Control Agency responded to the MTU report by recognising the need for vigilance and by incorporating adverse reactions reporting on unlicensed herbal remedies into their drug reaction monitoring function. As a further step to safeguard the patients/consumers an effective single regulatory system is required which would ensure the safety and quality of all herbal remedies and food supplements available in the UK.

    Full Text Available Herbal extracts are primarily added to the cosmetic formulations due to several associated properties such as antioxidant, anti inflammatory, antiseptic and antimicrobial properties. Even today, people in rural and urban areas depend upon herbs for traditional cosmetics. Information on the herbal cosmetics was collected via electronic search (using pub med, scifinder, Google Scholar and web of science and library search for articles published in peer-reviewed journals. Furthermore, information also was obtained from some local books on ethnopharmacology. The herbal extracts, as a whole or part, have been used for various ailments of the skin, hair, and dental care for overall appearance. Cosmetics alone are not sufficient to take care of skin and others body parts, it requires association of active ingredients to check the damage and ageing of the skin. Herbal cosmetics have gained much popularity among the population. Herbal cosmetics products claimed to have efficacy and intrinsic acceptability due to routine use in daily life and avoid the side effects which are commonly seen in synthetic products. Due to the awareness of the environmental damage caused by industrialization, a trend has developed to use products with natural ingredients. Various adverse effects may occur in the form of acute toxicity, percutaneous absorption, skin irritation, eye irritation, skin sensitization and photosensitization, sub chronic toxicity, mutagenicity, and photo toxicity by the usage of synthetic products that’s why today’s generation prefers herbal cosmetics for hair, skin and dental care. This review attempts and emphasizes the benefits of herbal extracts in cosmetics.

    Full Text Available It is still challenging and difficult to treat patients with eumycetoma; the current treatment has many side effects and has proven to be expensive and characterized by high recurrence rate, hence the poor patients' treatment compliance. Most of the patients are of low socio-economic status, have many financial constraints and hence, many of them rely on alternative and herbal medicine for the treatment of their disease. With this background, the current study was conducted to determine the prevalence of herbal medicine usage among patients with eumycetoma. This cross-sectional, observational, questionnaire-based study was conducted at the Mycetoma Research Center, University of Khartoum, Khartoum, Sudan. A convenience cohort of 311 patients with confirmed eumycetoma was invited to participate in the study after informed consent. The study showed that 42.4% of the study population used herbal medicine for the treatment of eumycetoma at some stage of their illness. The commonly used herbs were Moringa oleifera, Acacia nilotica, Citrullus colocynthis and Cuminum cyminum. Most of the patients claimed no benefits from the herbal treatment. Ninety one patients (29.3% had encountered complications with herbal treatment. The high prevalence of herbal treatment encountered in the study can be explained by the patients' dissatisfaction with the current medical therapeutic modalities. To reduce the high prevalence of herbal medicine usage, governmental control and health policies are mandatory; likewise, native healers need to be educated in that. Moringa oleifera was the commonly used herb in this study and many reports claimed medicinal properties of this tree; hence, further in-depth studies to determine the active ingredients in the different parts of the tree and its effect are required.

    It is still challenging and difficult to treat patients with eumycetoma; the current treatment has many side effects and has proven to be expensive and characterized by high recurrence rate, hence the poor patients' treatment compliance. Most of the patients are of low socio-economic status, have many financial constraints and hence, many of them rely on alternative and herbal medicine for the treatment of their disease. With this background, the current study was conducted to determine the prevalence of herbal medicine usage among patients with eumycetoma. This cross-sectional, observational, questionnaire-based study was conducted at the Mycetoma Research Center, University of Khartoum, Khartoum, Sudan. A convenience cohort of 311 patients with confirmed eumycetoma was invited to participate in the study after informed consent. The study showed that 42.4% of the study population used herbal medicine for the treatment of eumycetoma at some stage of their illness. The commonly used herbs were Moringa oleifera, Acacia nilotica, Citrullus colocynthis and Cuminum cyminum. Most of the patients claimed no benefits from the herbal treatment. Ninety one patients (29.3%) had encountered complications with herbal treatment. The high prevalence of herbal treatment encountered in the study can be explained by the patients' dissatisfaction with the current medical therapeutic modalities. To reduce the high prevalence of herbal medicine usage, governmental control and health policies are mandatory; likewise, native healers need to be educated in that. Moringa oleifera was the commonly used herb in this study and many reports claimed medicinal properties of this tree; hence, further in-depth studies to determine the active ingredients in the different parts of the tree and its effect are required.

    To describe the development and health claims of Asian herbal-tobacco cigarettes. Analysis of international news sources, company websites, and the transnational tobacco companies' (TTC) documents. PubMed searches of herbs and brands. Twenty-three brands were identified, mainly from China. Many products claimed to relieve respiratory symptoms and reduce toxins, with four herb-only products advertised for smoking cessation. No literature was found to verify the health claims, except one Korean trial of an herb-only product. Asian herbal-tobacco cigarettes were initially produced by China by the 1970s and introduced to Japan in the 1980s. Despite initial news about research demonstrating a safer cigarette, the TTC analyses of these cigarettes suggest that these early products were not palatable and had potentially toxic cardiovascular effects. By the late 1990s, China began producing more herbal-tobacco cigarettes in a renewed effort to reduce harmful constituents in cigarettes. After 2000, tobacco companies from Korea, Taiwan, and Thailand began producing similar products. Tobacco control groups in Japan, Taiwan, and Thailand voiced concern over the health claims of herbal-tobacco products. In 2005, China designated two herbal-tobacco brands as key for development. Asian herbal-tobacco cigarettes claim to reduce harm, but no published literature is available to verify these claims or investigate unidentified toxicities. The increase in Asian herbal-tobacco cigarette production by 2000 coincides with the Asian tobacco companies' regular scientific meetings with TTCs and their interest in harm reduction. Asia faces additional challenges in tobacco control with these culturally concordant products that may discourage smokers from quitting.

    The statutory regulation of herbal medicines is under review within the United Kingdom (UK) and by 2011 all herbal medicines will require either a Product Licence or a Traditional Herbal Registration. The species Scutellaria baicalensis has been shown to possess anti-inflammatory, anti-viral and anti-tumor properties and is one of the most widely used Chinese herbal extracts in Eastern and Western medicines. The bioactivity of this herbal medicine is due to the radical scavenging activities of the flavone components of which there are more than 60. This research has characterised 5 key flavones in 18 extracts of Scutellaria using a combination of HPLC with DAD and MS detection. Employing an internal standard approach, the validated HPLC method afforded good sensitivity and excellent assay precision. Assays for the ferric reducing antioxidant power (FRAP) and total phenol determinations enabled determination of the antioxidant coefficient (PAC) of each Scutellaria extract. The potential usefulness of employing multivariate statistical analysis using a combination of the key parameters collected namely, FRAP activity, total phenol content, levels of 5 flavone biomarkers and the PAC as a means of quality evaluation of the Scutellaria herbal extracts was investigated. The PAC value was predicted by soft independent modelling of class analogy (SIMCA) as being the most discriminatory parameter and applying this ranking the herbal extracts were grouped into 3 clusters. The second most influential parameter in determining the clustering of the samples was the level of baicalin in each extract. It is proposed that the PAC value alone or in combination with a chromatographic fingerprint of key biomarkers [e.g. baicalin or (baicalin+baicalein)] may be useful indicators to adopt for the quality control of S. baicalensis.

    The experiments aim to study the enrichment regularity of inorganic arsenic and total arsenic in kelp by analyzing the variation of inorganic and total arsenic in kelps which are from different maritime regions and different species during their growth. The content of inorganic arsenic is detected by HPLC-AFS, while the content of the total arsenic is examined by hydride atomic fluorescence spectrophotometry in GB/T 5009.11 -2003. The results show that the enrichment in kelps of total arsenic displays an increase trend in growing season, whereas the content of inorganic arsenic is decreasing. The percentage of inorganic arsenic in total arsenic decreased from 1.36%-1.47% (March) to 0.41%-0.57% (July). The enrichment of inorganic and total arsenic varies from kelp to kelp even they are cultivated in the same maritime region, meanwhile, the same types of kelps have dramatically different contents of inorganic and total arsenic, which depends on the variety of maritime regions. Judging from the data, the contents of inorganic arsenic in all examined kelps are far below the MRL and will have no negative effects on food safety. The study provides relevant theory foundation for food safety and processing.%通过分析不同养殖海域、不同品种海带中无机砷和总砷含量在养殖期间的变化,研究海带中总砷及无机砷的富集规律.结果显示,在生长期内海带对总砷的富集呈增长趋势,而无机砷含量则逐渐降低,其占总砷的比例由3月份1.36%~1.47%下降到7月份的0.41% ~0.57%;同一海域、不同品种的海带对总砷和无机砷的富集具有差异性;同时期在不同养殖海域采收的同品种海带总砷和无机砷含量差异显著.基于监测数据对海带中的无机砷进行分析,所有海带样品中无机砷含量远低于现行食品卫生标准中的限量要求,不对食用安全性造成影响.

    Objective: Unaccustomed and intense eccentric exercise is a common cause of delayed-onset muscle soreness (DOMS). There are multiple remedies for the treatment of DOMS, but its clinical and laboratory pieces of evidence are scarce. Currently, the treatments proposed for DOMS are numerous and include pharmaceuticals, herbal remedies, stretching, massage, nutritional supplements, and other alternatives. To find a holistic treatment with effective pain relief and minimum side effects, complementary and alternative medicine, including herbal therapies, plays a main role. Methods: In this review, the existing published studies investigating the efficacy of herbal and natural supplementation therapies for the prevention or treatment of side effects, symptoms, and signs of DOMS are summarized. Results: Previous studies have documented the efficacy of herbal therapies to treat pain, inflammation, as well as laboratory and clinical side effects of DOMS. Conclusion: The use of herbs in DOMS seems safer and has lower side effects than pharmacotherapy. However, the potential for side effects and drug interactions should be considered. PMID:28265543

    Graphical abstract: -- Highlights: •Similarity analyses of herbal fingerprints are reviewed. •Different (dis)similarity approaches are discussed. •(Dis)similarity-metrics and exploratory-analysis approaches are illustrated. •Correlation and distance-based measures are overviewed. •Similarity analyses illustrated by several case studies. -- Abstract: Herbal medicines are becoming again more popular in the developed countries because being “natural” and people thus often assume that they are inherently safe. Herbs have also been used worldwide for many centuries in the traditional medicines. The concern of their safety and efficacy has grown since increasing western interest. Herbal materials and their extracts are very complex, often including hundreds of compounds. A thorough understanding of their chemical composition is essential for conducting a safety risk assessment. However, herbal material can show considerable variability. The chemical constituents and their amounts in a herb can be different, due to growing conditions, such as climate and soil, the drying process, the harvest season, etc. Among the analytical methods, chromatographic fingerprinting has been recommended as a potential and reliable methodology for the identification and quality control of herbal medicines. Identification is needed to avoid fraud and adulteration. Currently, analyzing chromatographic herbal fingerprint data sets has become one of the most applied tools in quality assessment of herbal materials. Mostly, the entire chromatographic profiles are used to identify or to evaluate the quality of the herbs investigated. Occasionally only a limited number of compounds are considered. One approach to the safety risk assessment is to determine whether the herbal material is substantially equivalent to that which is either readily consumed in the diet, has a history of application or has earlier been commercialized i.e. to what is considered as reference material.

    Large-scale natural disasters, such as earthquakes, tsunamis, volcanic eruptions, and typhoons, occur worldwide. After the Great East Japan earthquake and tsunami, our medical support operation's experiences suggested that traditional medicine might be useful for treating the various symptoms of the survivors. However, little information is available regarding herbal medicine treatment in such situations. Considering that further disasters will occur, we performed a literature review and summarized the traditional medicine approaches for treatment after large-scale disasters. We searched PubMed and Cochrane Library for articles written in English, and Ichushi for those written in Japanese. Articles published before 31 March 2016 were included. Keywords "disaster" and "herbal medicine" were used in our search. Among studies involving herbal medicine after a disaster, we found two randomized controlled trials investigating post-traumatic stress disorder (PTSD), three retrospective investigations of trauma or common diseases, and seven case series or case reports of dizziness, pain, and psychosomatic symptoms. In conclusion, herbal medicine has been used to treat trauma, PTSD, and other symptoms after disasters. However, few articles have been published, likely due to the difficulty in designing high quality studies in such situations. Further study will be needed to clarify the usefulness of herbal medicine after disasters.

    The use of herbal therapy in inflammatory bowel disease (IBD) is increasing worldwide. The aim of this study was to review the literature on the efficacy of herbal therapy in IBD patients. Studies on herbal therapy for IBD published in Medline and Embase were reviewed, and response to treatment and remission rates were recorded. Although the number of the relevant clinical studies is relatively small, it can be assumed that the efficacy of herbal therapies in IBD is promising. The most important clinical trials conducted so far refer to the use of mastic gum, tormentil extracts, wormwood herb, aloe vera, triticum aestivum, germinated barley foodstuff, and boswellia serrata. In ulcerative colitis, aloe vera gel, triticum aestivum, andrographis paniculata extract and topical Xilei-san were superior to placebo in inducing remission or clinical response, and curcumin was superior to placebo in maintaining remission; boswellia serrata gum resin and plantago ovata seeds were as effective as mesalazine, whereas oenothera biennis had similar relapse rates as ω-3 fatty acids in the treatment of ulcerative colitis. In Crohn's disease, mastic gum, Artemisia absinthium, and Tripterygium wilfordii were superior to placebo in inducing remission and preventing clinical postoperative recurrence, respectively. Herbal therapies exert their therapeutic benefit by different mechanisms including immune regulation, antioxidant activity, inhibition of leukotriene B4 and nuclear factor-kappa B, and antiplatelet activity. Large, double-blind clinical studies assessing the most commonly used natural substances should urgently be conducted.

    The pregnane X receptor (PXR) and constitutive androstane receptor (CAR) are two members of the nuclear receptor superfamily that regulate a broad range of genes involved in drug metabolism and transport. A variety of naturally occurring compounds present in herbal medicines were identified as ligands of PXR and CAR. Recently, accumulative evidences have revealed the PXR- and CAR-mediated herbal effect against multiple human diseases, including inflammatory bowel disease (IBD), cholestatic liver disease, and jaundice. The current review summarized the recent progress in identifying the expanding libraries of herbal medicine as ligands for PXR and CAR. Moreover, the potential for herbal medicines as promising therapeutic agents which were mainly regulated through PXR/CAR signaling pathways was also discussed. The discovery of herbal medicines as modulators of PXR and CAR, and their PXR- and CAR-mediated effect on human diseases will provide a basis for rational drug design, and eventually be explored as a novel therapeutic approach against human diseases.

    Full Text Available Herbal medicines are the oldest known remedies to mankind. Herbs have been used by all cultures throughout history but India has one of the oldest, and most diverse cultural living traditions associated with the use of medicinal plants. The use of these agents may have perioperative implications, which often is a result of various factors. The constituents of these medications may not be adequately described. Conventional agents like ste-roids, oral hypoglycaemic agent, nonsteroidal anti-inflammatory agents and antihistamines are frequently added to herbal medicines. Toxic materials like arsenic, mercury, lead, etc. have been detected from time to time in some herbs. The use of herbal medicines can result in drug interactions, most of which are less well defined. The interactions that are most important in the perioperative period include sympathomimetic, sedative, and coagulopathic effects. Less than 50% of patients admit to taking these medicines, which compounds the prob-lem. It is imperative that anaesthesiologists obtain a history of herbal medicine use from patients and anticipate the adverse drug interactions. In case of any doubt, it may be prudent to stop these herbal medicines atleast 2-3 weeks prior to anaesthesia and surgery.

    Herbs have been integral to both traditional and non-traditional forms of medicine dating back at least 5000 years. The enduring popularity of herbal medicines may be explained by the perception that herbs cause minimal unwanted side effects. More recently, scientists increasingly rely on modern scientific methods and evidence-based medicine to prove efficacy of herbal medicines and focus on better understanding of mechanisms of their action. However, information concerning quantitative human health benefits of herbal medicines is still rare or dispersed, limiting their proper valuation. Preparations from traditional medicinal plants are often used for wound healing purposes covering a broad area of different skin-related diseases. Herbal medicines in wound management involve disinfection, debridement, and provision of a suitable environment for aiding the natural course of healing. Here we report on 22 plants used as wound healing agents in traditional medicine around the world. The aim of this review is therefore to review herbal medicines, which pose great potential for effective treatment of minor wounds.

    Full Text Available Herbal-based products are becoming a widespread production trend among manufacturers for the domestic and international markets. As the production increases to meet the market demand, it is very crucial for the manufacturer to ensure that their products have met specific criteria and fulfil the intended quality determined by the quality controller. One famous herbal-based product is herbal tea. This paper investigates bio-inspired flavour assessments in a data fusion framework involving an e-nose and e-tongue. The objectives are to attain good classification of different types and brands of herbal tea, classification of different flavour masking effects and finally classification of different concentrations of herbal tea. Two data fusion levels were employed in this research, low level data fusion and intermediate level data fusion. Four classification approaches; LDA, SVM, KNN and PNN were examined in search of the best classifier to achieve the research objectives. In order to evaluate the classifiers’ performance, an error estimator based on k-fold cross validation and leave-one-out were applied. Classification based on GC-MS TIC data was also included as a comparison to the classification performance using fusion approaches. Generally, KNN outperformed the other classification techniques for the three flavour assessments in the low level data fusion and intermediate level data fusion. However, the classification results based on GC-MS TIC data are varied.

    2003-12-01

    Over the centuries, Chinese herbal drugs have served as a major source of medicines for the prevention and treatment of diseases including diabetes mellitus (known as 'Xiao-ke'). It is estimated that more than 200 species of plants exhibit hypoglycaemic properties, including many common plants, such as pumpkin, wheat, celery, wax guard, lotus root and bitter melon. To date, hundreds of herbs and traditional Chinese medicine formulas have been reported to have been used for the treatment of diabetes mellitus. This paper provides a brief review of the antidiabetic drugs of plant origin that have been approved by the Chinese health regulatory agency for commercial use in China. It was believed, through pharmacological studies, that medicinal herbs were meticulously organized in these antidiabetic drug formulas such that polysaccharide containing herbs restore the functions of pancreatic tissues and cause an increase in insulin output by the functional beta cells, while other ingredients enhance the microcirculation, increase the availability of insulin and facilitate the metabolism in insulin-dependent processes. Pharmacological and clinical evaluations indicated that these drugs had a mild, but significant, blood glucose lowering effect and that the long-term use of these agents may be advantageous over chemical drugs in alleviating some of the chronic diseases and complications caused by diabetes. Additionally, the use of these natural agents in conjunction with conventional drug treatments, such as a chemical agent or insulin, permits the use of lower doses of the drug and/or decreased frequency of administration which decreases the side effects most commonly observed.

    Many athletes report using a wide range of special sports foods and supplements. In the present study of 77 elite Australian swimmers, 99% of those surveyed reported the use of these special preparations, with 94% of swimmers reporting the use of non-food supplements. The most popular dietary supplements were vitamin or mineral supplements (used by 94% of the group), herbal preparations (61%), and creatine (31%). Eighty-seven percent of swimmers reported using a sports drink or other energy-providing sports food. In total, 207 different products were reported in this survey. Sports supplements, particularly supplements presented as pills or other non-food form, are poorly regulated in most countries, with little assurance of quality control. The risk of an inadvertent "positive doping test" through the use of sports supplements or sports foods is a small but real problem facing athletes who compete in events governed by anti-doping rules. The elite swimmers in this survey reported that information about the "doping safety" of supplements was important and should be funded by supplement manufacturers. Although it is challenging to provide such information, we suggest a model to provide an accredited testing program suitable for the Australian situation, with targeted athlete education about the "sports safety" of sports supplements and foods.

    Propionibacterium acnes (P. acnes), one of the anaerobic bacterium, causes inflammatory acne. To find a novel medication for treating the inflammation caused by P. acnes, we investigated the anti-bacterial and anti-inflammatory activities of several herbal extracts against P. acnes. The aqueous extracts from five dried herbs, Phellodendron amurense Rupr., Paeonia lactiflora Pallas., Houttuynia cordata Thunb., Agrimonia pilosa Ledeb. and Glycyrrhiza uralensis Fisch., were prepared and mixed. In this experiment, 1 mg/ml of the herbal extract mixture caused a decrease in the growth of P. acnes and reduced the production of pro-inflammatory cytokines, TNF-α, IL-8, IL-1β and IL-6, in human monocytic THP-1 cells treated with heat-killed P. acnes. Therefore, this herbal extract mixture may possess both anti-bacterial and anti-inflammatory activities against P. acnes and can be a novel therapeutic agent for treating inflammatory acne.

    2012-01-01

    Full Text Available Herbal medicines have been widely used all over the world since ancient times and have been recognized by physicians and patients for their better therapeutic value as they have fewer adverse effects as compared with modern medicines. Phytotherapeutics need a scientific approach to deliver the components in a sustained manner to increase patient compliance and avoid repeated administration. This can be achieved by designing novel drug delivery systems (NDDS for herbal constituents. NDDSs not only reduce the repeated administration to overcome non-compliance, but also help to increase the therapeutic value by reducing toxicity and increasing the bioavailability. One such novel approach is nanotechnology. Nano-sized drug delivery systems of herbal drugs have a potential future for enhancing the activity and overcoming problems associated with plant medicines . Hence, integration of the nanocarriers as a NDDS in the traditional medicine system is essential to conflict more chronic diseases like asthma, diabetes, cancer, and others.

    2011-12-01

    Herbal medicine long has been used in the management of sexual dysfunction, including erectile dysfunction. Many patients have attested to the efficacy of this treatment. However, is it evidence-based medicine? Studies have been done on animal models, mainly in the laboratory. However, randomized controlled trials on humans are scarce. The only herbal medications that have been studied for erectile dysfunction are Panax ginseng, Butea superba, Epimedium herbs (icariin), Tribulus terrestris, Securidaca longipedunculata, Piper guineense, and yohimbine. Of these, only Panax ginseng, B. superb, and yohimbine have published studies done on humans. Unfortunately, these published trials on humans were not robust. Many herbal therapies appear to have potential benefits, and similarly, the health risks of various phytotherapeutic compounds need to be elucidated. Properly designed human trials should be worked out and encouraged to determine the efficacy and safety of potential phytotherapies.

    Full Text Available Epidermal permeability barrier function plays a critical role in regulating cutaneous functions. Hence, researchers have been searching for effective and affordable regimens to enhance epidermal permeability barrier function. In addition to topical stratum corneum lipids, peroxisome proliferator-activated receptor, and liver X receptor ligands, herbal medicines have been proven to benefit epidermal permeability barrier function in both normal and diseased skin, including atopic dermatitis, glucocorticoid-induced skin damage, and UVB-damaged skin. The potential mechanisms by which herbal medicines improve the permeability barrier include stimulation of epidermal differentiation, lipid production, antimicrobial peptide expression, and antioxidation. Therefore, utilization of herbal medicines could be a valuable alternative approach to enhance epidermal permeability barrier function in order to prevent and/or treat skin disorders associated with permeability barrier abnormalities.

    Tribulus terrestris (TT) is a dicotyledonous herbal plant of the Zygophyllaceae family. In ancient medicine, extracts of the aerial parts and fruits have been used for its diuretic, tonic, and aphrodisiac properties. Today, TT is widely used by athletes and bodybuilders based on the belief, fueled by claims in marketing information, that it can enhance testosterone concentrations. To assess TT's effect on testosterone levels in human and animals, an electronic literature search out using seven databases and the patent database up to August 2013 was carried out. Randomized control trials, which included healthy human subjects ingesting TT as sole or combined supplement, along with animal studies with TT as a sole treatment across a number of species were included. Eleven studies met the inclusion criteria, including one patent application. The results showed that trials varied in duration, dosage and supplementation with TT as sole or combined treatment, rendering meta-analysis impossible. A limited number of animal studies displayed a significant increase in serum testosterone levels after TT administration, but this effect was only noted in humans when TT was part of a combined supplement administration. Literature available for the effectiveness of TT on enhancing testosterone concentrations is limited. Evidence to date suggests that TT is ineffective for increasing testosterone levels in humans, thus marketing claims are unsubstantiated. The nitric oxide release effect of TT may offer a plausible explanation for the observed physiological responses to TT supplementation, independent of the testosterone level.

    Full Text Available Seventy two rabbits (Hycole, (♂+♀ 5 weeks old were divided into 2 experimental (EG and one control (CG group. The feed mixture A in control (CG did not contain any coccidiostat. In the first experimental group (EG1 was tested a complete granulated mixture B enriched with 30 g dry extract Eleutherococcus senticosus per 100 kg mixture. The animals were fed mixture B in combination with probiotic strain Enterococcus faecium EF AL 41 applied orally at a dose (10 9 CFU. ml-1 500 μl per animal in drinking water during 21 days. In the second group (EG2 was tested complete granulated mixture B. The experiment lasted 42 days. Body weight and feed consumption were registered weekly. Samples of faeces were taken at days 1, 21 and 42 to monitor the counts and effect of natural substances. Blood samples were also taken to check biochemical parameters using commercial kits. The samples for microbiological analyses were treated by the standard microbiological method according to ISO with appropriate media. Results presented in this study introduce different mechanisms of action for different classes of feed additives and how these may influence the observed live performance benefits. Application of Eleutherococcus extract in combination with EF AL 41 strain in rabbits was beneficial for performance. Additives reduced counts of S. aureus and Clostridium-like sp in faeces. Bioactive substances can be beneficial for animal health as was repeatedly confirmed by our results (mortality in EG1- 12%, EG2 - 8% compared to CG- 17%.

    Strychnine is a highly toxic alkaloid found in both naturally occurring compounds and commercial products. Extracts of fruits from the strychnine plant have been used in Southeast Asia as remedies for various illnesses. We describe strychnine poisoning from ingestion of a Southeast Asian herbal supplement quantitatively confirmed by serum and urine analysis. A 40-year-old Cambodian woman presented to the emergency department with a complaint of jaw pain and spasms. The patient was staying with a relative and drank 2 oz from an unmarked bottle that she thought contained vodka. She then developed trismus and abdominal cramping, after which a family member said the bottle contained a compound called "slang nut." Her vital signs were as follows: heart rate 102 beats/min, blood pressure 142/72 mm Hg, respiratory rate 20 breaths/min, and oxygen level 100%. The physical examination revealed no significant abnormalities. Serum toxicologic screens were negative except for strychnine levels that revealed a serum concentration of 350 ng/mL and a urine concentration >200 ng/mL. The patient was observed for 2.5 h and discharged with no long-term complications. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Strychnine is a well-known compound that has been used in poisons, rodenticides, and performance enhancing drugs for years. In the Western world, strychnine is a much less common poisoning given that its use has been restricted because of the potential for severe toxicity; however, given its potentially high mortality, it is important to be aware of other sources of exposure, including those from herbal and homeopathic remedies.

    The present study aims to elucidate the roles of nitric oxide synthase activity, oxidative stress, inflammation, and apoptosis in penile toxicity of aging mice associated with excess manganese (Mn) treatment and to investigate the effect of oral treatment with the herbal formula B401 in this respect. ICR strain mice were divided into two groups: the vehicle (sham group) and the B401 (50 mg/kg) group. The mice were orally treated for 5 days; then a high single dose of MnCl2 (100 mg/kg) was given by intraperitoneal injection to the mice. One day after MnCl2 treatment, corpora cavernosal tissues of both Mn-treated mice and their controls were simultaneously sampled to examine their immunohistochemical staining and Western blot analysis. Nitric oxide (NO) production, levels of neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS), expression levels of factors governing angiogenesis (vascular endothelial growth factor), oxidative stress (catalase, superoxide dismutase 2,4-hydroxynonenal), inflammation (tumor necrosis factor alpha), apoptosis (B-cell lymphoma 2 [Bcl-2], Bcl-2-associated X protein [Bax], cleaved poly(adenosine diphosphate-ribose) polymerase [c-PARP], cytochrome C, caspase-12, and caspase-3) were evaluated in penile corpus cavernosum of the mice. We found that penile toxicity in the mice was enhanced under excess Mn treatment through reduction of NOS activity and increase in oxidative stress, inflammation, and apoptosis in the penile cavernous tissue. Furthermore, the penile toxicity in mice with manganism was alleviated by oral B401 treatment through enhancement of both nitric oxide synthesis and angiogenesis, with simultaneous reduction of oxidative stress, inflammation, and apoptosis in penile corpus cavernosum. We suggest that the herbal formula B401 may serve as a potential dietotherapeutic supplement for penile toxicity or dysfunction in aging males.

    We prove that a module M is cofinitely weak supplemented or briefly cws (i.e., every submodule N of M with M/N finitely generated, has a weak supplement) if and only if every maximal submodule has a weak supplement. If M is a cws-module then every M-generated module is a cws-module. Every module is cws if and only if the ring is semilocal. We study also modules, whose finitely generated submodules have weak supplements.

    The aim of the study is to examine the influence of the outplanting time on the cultivation of the kelp Laminaria saccharina in the northwestern Spain, close to its southern limit of distribution in the North Atlantic coast. We compared two L. saccharina cultures outplanted in February and December. We found that the starting time of outplanting affects to the yield and the substantiality value, as well as the growth rate. The yield, the substantiality value and the growth rates of L. saccharina sporophytes obtained for the trial outplanted in December were significantly higher than those in February. These results can be mainly explained by the effect of temperature on the growth of L. saccharina sporophytes during cultivation. On the other hand, our results show that even in the southern limit of distribution of L. saccharina, the cultivation of this species was very profitable in high yield and quality.

    Full Text Available The invasive kelp Undaria pinnatifida (Phaeophyceae, Laminariales was first reported in Golfo Nuevo in 1992 and since then it has spread widely over more than 170 km, all along the northern Patagonian coast, Argentina. Field observations in the region have indicated the potential role of invertebrate grazers, like the sea urchins Arbacia dufresnii and Pseudechinus magellanicus and the gastropod Tegula patagonica, in controlling algal density. Laboratory experiments were conducted to ascertain whether, and if so, to what extent these grazers actually feed on the algae. The studied sea urchins fed on the alga, whereas the snail scraped off biofouling adhered to its surface. Higher densities of grazers were observed on the kelp during summer and might be attributed to increasing in metabolism with increasing temperature, and degradation of blades and sporophylls, which possibly increase their palatability.El alga invasora Undaria pinnatifida (Phaeophyceae, Laminariales fue reportada por primera vez en Golfo Nuevo en 1992, dispersándose ampliamente a lo largo de 170 km de costa en el norte de la Patagonia, Argentina. Observaciones de campo hechas en los erizos de mar Arbacia dufresnii y Pseudechinus magellanicus y en el gasterópodo Tegula patagonica evidenciaron que son posibles consumidores de Undaria pinnatifida en la población local. Se realizaron experimentos de laboratorio con el objetivo de probar si estos pastoreadores eran capaces de consumir el alga. Los erizos de mar estudiados consumen el alga, mientras que el gasterópodo ramonea los epibiontes presentes sobre su superficie. Altas densidades de ramoneadores fueron encontradas sobre el alga durante el verano y podrían ser atribuidas a un aumento del su metabolismo con el aumento de la temperatura y a la degradación de las láminas y esporofilos, lo cual posiblemente aumente la palatabilidad del alga.

    Toxicity studies were conducted by the National Toxicology Program (NTP) to provide information on the potential for toxicity from long-term use of commonly used herbal medicines. Here, we review the findings from these NTP toxicology/carcinogenesis 2-year rodent studies of 7 commonly used herbs. In these studies, the individual herb or herbal product was administered to F344/N rats and B6C3F1 mice by oral administration for up to 2 years. The spectrum of carcinogenic responses ranged from no or equivocal evidence for carcinogenic activity (ginseng, milk thistle, and turmeric oleoresin) to a liver tumor response (ginkgo, goldenseal, kava), thyroid tumor response (ginkgo), or an intestinal tumor response (Aloe vera whole leaf nondecolorized extract). Different mechanisms may be involved in the occurrence of liver (ginkgo, goldenseal, and kava kava) and gastrointestinal toxicity (turmeric oleoresin and Aloe vera whole leaf nondecolorized extract), while the toxic lesion is the same. The results from these hazard identification toxicity/carcinogenesis studies along with those from ongoing National Institute of Health clinical trials of herbal medicines provide more complete information on the risks and benefits from herbal medicine use in the general population.

  17. Traditional herbal medicines worldwide, from reappraisal to assessment in Europe.

    2014-12-02

    Since 2004 the regulatory framework within the European Union has a specific assessment procedure for herbal medicinal products, with a medicinal use based on traditional practice. The main requirement concerning the traditional use is focussed on the period of time for medical use: at least 30 years, including 15 years in the EU. In addition to requirements for quality and safety, an evaluation of pharmacological effects or efficacy based on long-standing use, is a main objective. "Traditional Use" however encompasses European, and non-European traditional use. Outside the EU, the medicinal use of herbal substances, preparations, and combinations is well-known, with a long history, which is well-documented in the different systems of medical practice. This has been addressed by WHO, but it has been acknowledged also by European Commission that herbal products from other systems of medicine, can be subject to the procedure for traditional herbal medicinal products. This paper will focus on the possibilities, restraints, and challenges of regulatory practice in the European Union regarding these category of medicinal products.

  18. PHYTOSOMES: A NOVEL DRUG DELIVERY FOR HERBAL EXTRACTS

    Directory of Open Access Journals (Sweden)

    M. Sravanthi* and J. Shiva Krishna

    2013-03-01

    Full Text Available ABSTRACT: Novel drug delivery system is a novel approach to drug delivery that addresses the limitations of the traditional drug delivery systems. Our country has a vast knowledge base of Ayurveda whose potential is only being realized in the recent years. The effectiveness of any herbal medication is dependent on the delivery of effective level of the therapeutically active compound. Severe limitation exists in their bioavailability when administered orally or topically. Phytosomes are recently introduced herbal formulations that are better absorbed and as a result produce better bioavailability and actions than the conventional phyto-molecules or botanical extracts. In the recent days, most of the prevailing diseases and nutritional disorders are treated with natural medicines. Several plant extracts and phytoconstituents, despite having excellent bioactivity in vitro demonstrate less or no in vivo actions due to their poor lipid solubility or improper molecular size or both, resulting in poor absorption and bioavailability. So, much work has been directed towards the development of new concept in herbal delivery system i.e., “phytosomes” which are better absorbed, utilized and as a result produce better results than conventional herbal extracts owing to the presence of phosphatidylcholine which likely pushes the phytoconstituent through the intestinal epithelial cell outer membrane, subsequently accessing the bloodstream phytosomes have improved pharmacokinetic and pharmacological parameter which in result can advantageously be used in the treatment of the acute and chronic liver disease of toxic metabolic or infective origin or of degenerative nature.

    This paper investigates some of the ways that Chinese medicine has been transferred to the Western world and to Islamic territories. During the Golden Age of Islam (8th to 13th century CE), the herbal drug trade promoted significant commercial and scientific exchange between China and the Muslim world. Chinese herbal drugs have been described by medieval Muslim medical scholars such as Tabari (870 CE), Rhazes (925 CE), Haly Abbas (982 CE), Avicenna (1037 CE) and Jurjani (1137 CE). The term al-sin (the Arabic word for China) is used 46 times in Avicenna’s Canon of Medicine in reference to herbal drugs imported from China. Cinnamon (dar sini; “Chinese herb”), wild ginger (asaron), rhubarb (rivand-e sini), nutmeg (basbasa), incense tree wood (ood), cubeb (kababe) and sandalwood (sandal) were the most frequently mentioned Chinese herbs in Islamic medical books. There are also multiple similarities between the clinical uses of these herbs in both medical systems. It appears that Chinese herbal drugs were a major component of the exchange of goods and knowledge between China and the Islamic and later to the Western world amid this era.
