Ethnobotanical uses, secondary metabolites and biological activities of Mashua (Tropaeolum tuberosum Ruíz & Pavón)

ConclusionsT. tuberosum has been tested for various biological activities and the extracts (tubers in particular) demonstrated a promising potential as an antibacterial, antioxidant, anti-inflammatory and inhibitors of benign prostatic hyperplasia. A lack of alignment between the ethno-medicinal uses and existing biological screenings was observed, indicating the need to explore its potential for the treatment against respiratory affections, urinary affections and blood diseases. Likewise, it is necessary to analyse deeply the relationship that exists between the different tuber colours of T. tuberosum and its use for the treatment of certain diseases. Validation of clinical studies of the antibacterial, antioxidant/anti-inflammatory, anti-spermatogenic activities and as inhibitors of benign prostatic hyperplasia is required. Moreover, studies on the toxicity, bioavailability, and pharmacokinetics, in addition to clinical trials, are indispensable for assessing the safety and efficacy of the active metabolites or extracts obtained from T. tuberosum. Other areas that need investigation are the development of future applications based on their active metabolites, such as neurodegenerative diseases (Alzheimer's disease, Parkinson's disease, Huntington's disease).Finally, the work purposes to motivate other research groups to carry out a series of scientific studies that can fill the gaps that exist with respect to Mashua properties, and thus be able to change the focus of T. tub...

In this study, the effects of four different hulling methods, included natural heaping (NH), manually hulled (MH), solid ethylene-releasing agent (SERA) and immersion in ethephon (IE), on odor, tastes, nutritional compounds (fat, protein, and fatty acids), antioxidant activities and total phenols content of green walnut were investigated. The result indicated that SERA treated group had the highest hulling rate (82.80%), followed by IE (54.84%) and NH (46.24%), however, both odor and taste of fresh walnut kernels were unpleasant in SERA and IE treatments groups. Additionally, the lowest antioxidant activity (AAC) (63.34), ...

Publication date: May 2020Source: Food Hydrocolloids, Volume 102Author(s): Mingyuan Huang, Huhu Wang, Xinglian Xu, Xuqiu Lu, Xiangyu Song, Guanghong ZhouAbstractSpoilage of ready-to-eat carbonado chicken during storage usually causes safety concerns and economic losses. A novel edible nanoemulsion coating with natural antimicrobial and antioxidant was applied to improve carbonado chicken shelf life. The nanoemulsion based on gelatin and chitosan incorporated a mixture of rosemary extract and ε-poly-l-lysine (ε-PL) and was fabricated by high pressure homogenization. Emulsion droplet size and ζ-potential...

Ojeda-Amador, María Desamparados SalvadorAbstractThe purpose of this research was the development of functional edible oils with potential health promoting effects, enriched with phenolic-rich extracts obtained from pistachio and walnut. A high phenolic content, 10860 mg/kg and 7030 mg/kg in walnut and pistachio kernels respectively, with a corresponding strong radical scavenging effect (DPPH, 106 and 20 mmol/kg Trolox) were found. The remarkable antioxidant capacity of the ...

In this study, production of peptide fractions with different molecular weights (10, 30, and 100 KDa) from flaxseed hydrolysates was investigated. The peptide-fraction with lowest MW (10 KDa) showed the highest antioxidant activity (AA); therefore, selected and loaded into nanoliposomes. Then, the effect of chitosan coating (0.1–0.8% w/v) on the physicochemical features, stability, and release rate of loaded nanoliposomes was assessed. Nanoliposomes coated with 0.4% chitosan exhibited a higher physical stability and encapsulation efficiency (EE) compared with other samples. Then, stabilization of uncoated/coated nano...

ConclusionPathway-focused analysis of redox gene expression allowed us to highlight delayed oxidative alterations in monocytes exposed in vitro to γ rays, indicating that a chronic oxidative activity is persisting long after irradiation. Moreover, we emphasized that the necessity to boost the endogenous antioxidant system in normal cells exposed to higher doses of γ rays, in order to protect them against the deleterious effects of radiation. A therapeutic option might be the pharmacological activation of the transcription factor NRF2 which can rapidly react to even small increases in intracellular oxidants and ...

Authors: Togha M, Bahrpeyma F, Jafari M, Nasiri A Abstract BACKGROUND: Cervicogenic headache (CeH) is among the common types of headache which has an undesirable influence on the quality of life. The myofascial trigger point (MTrP) within the sternocleidomastoid (SCM) muscle is one of the most important causes of CeH. OBJECTIVE: The purpose of this study was to compare the effect of dry needling (DN) and ischemic compression (IC) on the headache symptoms as well as MTrP-related features in subjects with CeH originating from MTrPs of the SCM muscle using a sonographic method. METHODS: A total of 29 female su...

Conclusion: Repeated colonoscopies can be perceived as both an assurance of life and a reminder of a lifelong illness. Healthcare professionals need to provide support in terms of awareness of patients' vulnerability, despite extensive experience of the colonoscopy procedure. For example, person-centred care and continuity in care are potential interventions based on the results of this study. Another important aspect of care is to minimise interference in everyday life to prevent feelings of loss of the healthy self, for example by self-administrated outpatient booking systems.Summarize the established knowledge on this s...

This study emphasis the production of yellow pigment from endolichenic Bacillus sp. isolated from the lichen Dirinaria aegialita (Afzel. ex Ach.) B.J. Moore. Yellow pigment-producing twenty different strains were investigated. The hyperactive pigment-producing bacterial strain was identified as Bacillus gibsonii based on 99 % sequence similarity. Maximum bacterial pigment production appeared in Luria Bertani medium. Methanol extraction of the pigment and its partial purification using TLC was carried out. Furthermore, isolated pigments were characterized using UV-visible spectroscopy, FTIR spectroscopy, and GC-MS results r...
