Phenolic content and antioxidant capacity of infusions herbs: Optimization of phenolic extraction and HPLC-DAD method.
Abstract
The aim of this work was to investigate the phenolic content and antioxidant capacity of infusions of commercial herb samples (fennel, anise, peppermint, lemon grass and lemon balm) popularly consumed in Brazil. The infusion preparation for phenolic extraction was optimized using multivariate planning. Spectrophotometric methods were used to determine in vitro antioxidant activity and total phenolic and flavonoid content. Peppermint infusions had higher phenolic content and antioxidant potential. It was developed and validated a method by HPLC-DAD for the determination of caffeine, phenolic acids ...

Molecules, Vol. 25, Pages 4841: Pimpinella anisum Essential Oil Nanoemulsion Toxicity against Tribolium castaneum? Shedding Light on Its Interactions with Aspartate Aminotransferase and Alanine Aminotransferase by Molecular Docking
ll’Acqua
The insecticidal activity is the result of a series of complex interactions between toxic substances as ligands and insect’s enzymes as targets. Actually, synthetic insecticides used in pest control programs are harmful to the environment and may affect non-target organisms; thus, the use of natural products as pest control agents can be very attractive. In the present work, the toxic effect of aniseed (Pimpinella anisum L.) essential oil (EO) and its nanoemulsion (NE) against the red flour beetle Tribolium castaneum, has been evaluated. To assess the EO mode of action, the impact of sub-lethal...

A Descriptive Study of Pain Relief Practices Among Student-Athletes in Palestine: Focus on Non-Steroidal Anti-Inflammatory Drugs, and Complementary Medicine and Alternative Medicine Use
This study shows a high prevalence of NSAIDs and CAM use among student-athletes in Palestine with a low level of knowledge and awareness of their side-effects. Therefore, education strategies that focus on enhancing and improving student-athletes’ knowledge of the proper use and the possible side-effects of NSAIDs and CAM are needed.

Enhancing Effects of Herbs on the Salty Taste Perception of Saline.
Authors: Kohri T, Kira R, Myojin C, Kawanishi M, Tomotake H
Abstract
In many countries, excessive consumption of sodium chloride (salt) has become a serious social problem and reducing salt has been required. Herbs have been reported to enhance the saltiness of food; however, few studies have focused on the numerical evaluation of the degree of saltiness enhancement by herbs. The purpose of this study was to quantify the degree of saltiness enhancement by herbs via human sensory evaluation using a visual analog scale (VAS). The sensory evaluation was conducted on 69 students who were able to arrange the fi...

Subjective and Objective Assessments of Post-traumatic Olfactory Dysfunction
Conclusions: Findings from our study indicate the application of both subjective and objective examinations in the evaluation of patients with olfactory impairment. In the diagnosis of post-traumatic anosmia or hyposmia, objective examinations are particularly useful when the patients' level of cognition may be impaired or when subjects may be exaggerating their olfactory defects for a secondary gain. The diagnosis of damage to the olfactory system, specifically in the receptive part of the olfactory pathway, can be established in patients who showed reduced amplitudes or absent cortical responses in addition to absent odo...

trans-Anethole Abrogates Cell Proliferation and Induces Apoptosis through the Mitochondrial-Mediated Pathway in Human Osteosarcoma Cells.
Abstract
trans-Anethole, the major bioactive component of Illicium verum Hook. commonly known as star anise exhibits various pharmacological activities including anti-inflammatory, antimicrobial, insecticidal, and antitumor. Osteosarcoma is an extremely aggressive malignant bone tumor that affects children and young adults and accounts for around 60% of all sarcomas. The study was planned to evaluate the potential of trans-Anethole against Human osteosarcoma cell line MG-63. The antiproliferative activity of trans-Anethole was assessed by MTT assay. trans-Anethole exhibited apoptotic cell death as monitore...

Effect of essential oils or saponins alone or in combination on productive performance, intestinal morphology and digestive enzymes' activity of broiler chickens
This study was carried out to evaluate the effect of essential oils or saponins alone or in combination on productive performance, intestinal morphology, and digestive enzymes' activity in broilers. Four hundred one ‐day‐old male broiler chickens were randomly assigned to four treatments, each with 5 replicates. The birds were fed experimental diets contained either no phytogenic feed additives (control) or were supplemented with 25.0 mg/kg of an essential oil blend from star anise, rosemary, thyme and ore gano (essential oils); 46.0 mg/kg of a Quillaja saponin blend (saponins); or a combination of both phytogenic pr...

[Hypokalemia with pseudo-hyperaldosteronism: Is it Lidl ® syndrome?]
DISCUSSION: The consumption of glycyrrhizin is a well-known aetiology for pseudo-hyperaldosteronism. It is commonly mentioned amongst excessive consumers of liquorice or of non-alcoholic anise drinks. Drinks that are derived from original pastis contain varying levels of glycyrrhizin, which is used as a flavour enhancer and can become toxic in cases of prolonged and important consumption.
