The species of A. vera are widely distributed and cultivated throughout the world. Objective: This review article aims to present an account of information on phytochemistry, pharmacological properties of bioactive compounds from A. vera highlighting the mechanism of action and functional food supplement to improve human health. The development of A. vera based phytomedicines and its future trends were also evaluated. Methods: A bibliographic search of scientific literature published till March 2020 was carried out from the scientific databases and different search engines such as PubMed, ScienceDirect, Cochrane library, and Scopus. The keywords used in several combinations included: Aloe vera, phytochemistry, pharmacological activity, treatment, prevention, disease, health, in vitro, in vivo and clinical studies. From eligible articles, the data were independently extracted by standard data extraction method. Results: A. vera is a good source of bioactive compounds. A. vera has been reported for numerous therapeutic applications. Besides several valuable therapeutic potentials, the plant has been also used as crop and food preservation as well as a functional food supplement due to the presence of high content of carbohydrates, vitamins and several antioxidant molecules. Its oral ingestion has been related to diarrhea, electrolyte imbalance, kidney dysfunction, drug interactions, dermatitis, erythema, and phototoxicity. Conclusion: Although there are several A. vera-based products available, the knowledge on the relationship between biological and therapeutic properties should be clearly defined to ascertain the exact action mechanism(s) to develop new drugs.

Lepidium meyenii(maca) is a Peruvian plant of the Brassicaceae family cultivated for more than 2000 years, which grows exclusively in the central Andes between 4000 and 4500 m altitude. Maca is used as a food supplement and also for its medicinal properties described traditionally. Since the 90s of the XX century, an increasing interest in products from maca has been observed in many parts of the world. In the last decade, exportation of maca from Peru has increased from 1,415,000 USD in 2001 to USD 6,170,000 USD in 2010. Experimental scientific evidence showed that maca has nutritional, energizer, and fertility-enhancer properties, and it acts on sexual dysfunctions, osteoporosis, benign prostatic hyperplasia, memory and learning, and protects skin against ultraviolet radiation. Clinical trials showed efficacy of maca on sexual dysfunctions as well as increasing sperm count and motility. Maca is a plant with great potential as an adaptogen and appears to be promising as a nutraceutical in the prevention of several diseases.

In addition to its nutritional value, Paullinia cupana (guarana) is commonly used in traditional medicine, known for its stimulant and medicinal properties. This investigation evaluated the effects of a guarana extract in combination with whole-body vibration (WBV) exercises on Wistar rats. Rats (male, n = 20) were divided into the following four groups: control (CON), treated with guarana (GUA), submitted to 50 Hz of WBV (WBV-E), treated with guarana and submitted to 50 Hz of WBV (GUA + WBV-E), daily for 6-weeks. Guarana altered (p < 0.05) the uptake of the radiopharmaceutical sodium pertechnetate (Na99mTcO4) in muscle. Additionally, it modified the stool consistency, and in combination with WBV decreased the food intake without modifying body mass. The levels of calcium increased in the groups submitted to WBV exercises (WBV-E and GUA + WBV-E) as compared with the GUA group. The outcomes provide additional evidence of the biological effects of guarana separately or in combination with WBV and supports the use of guarana as a functional food.

All over the world, a large proportion of the population consume insects as part of their diet. In Western countries, however, the consumption of insects is perceived as a negative phenomenon. The consumption of insects worldwide can be considered in two ways: on the one hand, as a source of protein in countries affected by hunger, while, on the other, as an alternative protein in highly-developed regions, in response to the need for implementing policies of sustainable development. This review focused on both the regulations concerning the production and marketing of insects in Europe and the characteristics of edible insects that are most likely to establish a presence on the European market. The paper indicates numerous advantages of the consumption of insects, not only as a valuable source of protein but also as a raw material rich in valuable fatty acids, vitamins, and mineral salts. Attention was paid to the functional properties of proteins derived from insects, and to the possibility for using them in the production of functional food. The study also addresses the hazards which undoubtedly contribute to the mistrust and lowered acceptance of European consumers and points to the potential gaps in the knowledge concerning the breeding conditions, raw material processing and health safety. This set of analyzed data allows us to look optimistically at the possibilities for the development of edible insect-based foods, particularly in Europe.

Abstract Background The genus Arisaema (Areaceae), popularly known as cobra lilies and jack in pulpit is mainly found in temperate to tropical areas of all continents except South America, Europe and Australia and contain about more than 250 species. Arisaema genus is being used by the different folks of human populations for medicinal as well as food purposes. Arisaema plants are used for the treatment of different types of diseases. There have been several attempts to highlight different aspects of genus Arisaema by describing it in terms of phytochemistry and medicinal uses. The present study is, however, an attempt to put together all the former data available related to the phytochemistry and medicinal uses of genus Arisaema. Main body The phytochemicals of the plant include alkaloids, phenols, terpenes, flavonoids, lectins, saponins, glycosides, triterpenoids, stigmasterols, n-alkanes, n-alkanols sitosterols, campesterol, oxalates, coumarins, tannins etc. Moreover, the properties such as antioxidant, antifungal, antibacterial, insecticidal, antimicrobial, cytotoxic, nematocidal, antiallergic antitumour and anticancer activities are also shown by the plants belonging to genus Arisaema. Arisaema plants have been traditionally used to treat various ailments such as resolving phlegm, dampness, and to treat asthma, bronchitis, cold, cough, and laryngitis etc. It has been found that there are several species which are toxic by nature. The development of clinical applications of arisaematis rhizomes had been seriously constrained due to its toxic properties like, mouth and lingua pain, even respiration slowing and suffocation, mucous membrane and skin irritation etc. and this toxicity of arisaematis rhizomes is due to raphide components. Conclusions The collection of data available on the phytochemistry of genus Arisaema is not sufficient as further work is required to do on phytochemical and medicinal basis. The data available on phytochemistry and medicinal properties of the plants belonging to genus Arisaema throws light on various species of Arisaema which are medicinally important and have been exploited to treat different types of diseases in the world.

Radiation therapy is one of the main modalities to treat cancer/tumor. The response to radiation therapy, however, can be influenced by physiological and/or pathological conditions in the target tissues, especially by the low partial oxygen pressure and altered redox status in cancer/tumor tissues. Visualizing such cancer/tumor patho-physiological microenvironment would be a useful not only for planning radiotherapy but also to detect cancer/tumor in an earlier stage. Tumor hypoxia could be sensed by positron emission tomography (PET), electron paramagnetic resonance (EPR) oxygen mapping, and in vivo dynamic nuclear polarization (DNP) MRI. Tissue oxygenation could be visualized on a real-time basis by blood oxygen level dependent (BOLD) and/or tissue oxygen level dependent (TOLD) MRI signal. EPR imaging (EPRI) and/or T1-weighted MRI techniques can visualize tissue redox status non-invasively based on paramagnetic and diamagnetic conversions of nitroxyl radical contrast agent. 13C-DNP MRI can visualize glycometabolism of tumor/cancer tissues. Accurate co-registration of those multimodal images could make mechanisms of drug and/or relation of resulted biological effects clear. A multimodal instrument, such as PET-MRI, may have another possibility to link multiple functions. Functional imaging techniques individually developed to date have been converged on the concept of theranostics.

Introduction: Toxoplasmosis is a zoonosis that represents a serious public health problem, caused by Toxoplasma gondii, which affects 20-90% of the world human population [1,2]. It is a serious problem especially when considering the congenital transmission due to congenital sequels. Treatment with highly diluted substances is one of the alternative/complementary medicines most employed in the world [3,4]. The current ethical rules regarding the number of animals used in animal experimental protocols with the use of more conservative statistical methods [5] can not enhance the biological effects of highly diluted substances observed by the experience of the researcher. Aim: To evaluate the minimum number of animals per group to achieve a significant difference among the groups of animals treated with biotherapic T. gondii and infected with the protozoan regarding the number of cysts observed in the brain. Material and methods: A blind randomized controlled trial was performed using eleven Swiss male mice, aged 57 days, divided into two groups: BIOT-200DH - treated with biotherapic (n=6) and CONTROL - treated with hydroalcoholic solution 7% (n=7).The animals of the group BIOT-200DH were treated for 3 consecutive days in a single dose 0.1ml/dose/day. The animals of BIOT – 200DH group were orally infected with 20 cysts of ME49-T. gondii. The animals of the control group were treated with cereal alcohol 7% (n=7) for 3 consecutive days and then were infected with 20 cysts of ME49 -T. gondii orally. The biotherapic 200DH T. gondii was prepared with homogenized mouse brain, with 20 cysts of T. gondii / 100μL according to the Brazilian Homeopathic Pharmacopoeia [6] in laminar flow. After 60 days post-infection the animals were killed in a chamber saturated with halothane, the brains were homogenized and resuspended in 1 ml of saline solution. Cysts were counted in 25 ml of this suspension, covered with a 24x24 mm coverglass, examined in its full length. This study was approved by the Ethics Committee for animal experimentation of the UEM - Protocol 036/2009. The data were compared using the tests Mann Whitney and Bootstrap [7] with the statistical software BioStat 5.0. Results and discussion: There was no significant difference when analyzed with the Mann-Whitney, even multiplying the "n" ten times (p=0.0618). The number of cysts observed in BIOT 200DH group was 4.5 ± 3.3 and 12.8 ± 9.7 in the CONTROL group. Table 1 shows the results obtained using the bootstrap analysis for each data changed from 2n until 2n+5, and their respective p-values. With the inclusion of more elements in the different groups, tested one by one, randomly, increasing gradually the samples, we observed the sample size needed to statistically confirm the results seen experimentally. Using 17 mice in group BIOT 200DH and 19 in the CONTROL group we have already observed statistical significance. This result suggests that experiments involving highly diluted substances and infection of mice with T. gondii should work with experimental groups with 17 animals at least. Despite the current and relevant ethical discussions about the number of animals used for experimental procedures the number of animals involved in each experiment must meet the characteristics of each item to be studied. In the case of experiments involving highly diluted substances, experimental animal models are still rudimentary and the biological effects observed appear to be also individualized, as described in literature for homeopathy [8]. The fact that the statistical significance was achieved by increasing the sample observed in this trial, tell us about a rare event, with a strong individual behavior, difficult to demonstrate in a result set, treated simply with a comparison of means or medians. Conclusion: Bootstrap seems to be an interesting methodology for the analysis of data obtained from experiments with highly diluted substances. Experiments involving highly diluted substances and infection of mice with T. gondii should be better work with experimental groups using 17 animals at least.

Phytosanitary Measures

With the formation of the World Trade Organization (WTO) in 1995, specific principles and rules were conceived. These rules, or Sanitary & Phytosanitary Measures (e.g., SPS Agreement), relate to three primary issues or concerns: food safety, animal health, and plant health. While still controversial, the WTO/SPS Agreement does provide for more detailed control of food safety concerns and for more standardization and harmonization regarding rules and regulations. This document is FSHN034, one of a series of the Food Science and Human Nutrition Department, Florida Cooperative Extension Service, IFAS, University of Florida.
