Resumen

The thyroid hormones change the rate of basal metabolism, modulating the consumption of oxygen and causing production of reactive oxygen species, which leads to the development of oxidative stress and DNA strand breaks. Olive (Olea europaeaL.) leaf contains many potentially bioactive compounds, making it one of the most potent natural antioxidants. The objective of this study was to evaluate the genotoxicity of L-thyroxine and to investigate antioxidative and antigenotoxic potential of the standardized oleuropein-rich dry olive leaf extract (DOLE) against hydrogen peroxide and L-thyroxine-indu

Resumen

Benolea® (EFLA®943) is a standardized dry olive leaf extract (DOLE) considered safe for food consumption and has demonstrated superior pharmaceutical benefits such as antioxidant, anti-obesity, and anti-hypertensive activities. However, there is no study on its effects on melanogenesis yet. Disruption in the sequence of steps in melanogenesis can lead to hypopigmentary disorders which occur due to reduced production or export of pigment melanin in the skin. There is a need for safe and nontoxic therapeutics for the treatment of hypopigmentation disorders. Herein, we studied the effects of DOLE

Resumen

Nowadays a possible strategy in food preservation consists of the use of active and functional packaging to improve safety and ensure a longer shelf life of food products. Many studies refer to chitosan-based films because of the already-known chitosan (CH) antibacterial and antifungal activity. In this work, we developed CH-based films containing Dried Olive Leaf Extract (DOLE) obtained by Naviglio extractor, with the aim to investigate the polyphenols yield and the antioxidant activity of this extract entrapped in CH-based-edible films.

Resumen

The quest of geological proxies to evaluate low-latitude hydrological changes at a planetary scale remains an ongoing issue. The Dole effect is such a potential proxy owing to its global character. We propose a new approach to recalculate the fluctuation of the Dole effect (∆DE*) over the past 800 thousand years (ka). The ∆DE* calculated this way is dominated by precession cycles alone, with lesser variance in the obliquity bands and almost no variance in the eccentricity bands. Moreover, the ∆DE* is notably correlated with Chinese stalagmite δ18O record over the past 640 ka; simulated terrest

Attitudes towards a departing administration can help shape attitudes towards candidates, especially when the incumbent vice-president is one of the candidates. This succession effect was apparent in the 1988 presidential election, when Vice-President Bush benefited from the enduring popularity of retiring President Reagan. This article develops a model in which succession effects, the net candidate score and party identification affect the general election vote.

Resumen

The study of extra solar planets represents a new exciting frontier for modern astronomy. Most of the results on extrasolar systems are obtained with Doppler surveys. Here we suggest a different approach aimed to study the polarimetric properties of the residual interplanetary dust. Dust can produce observable effects such as infrared emission excess (Beckwith & Sargent 1996; Spangler et al. 2001) and partial polarization of the star light via scattering (Mauron & Dole 1998; Yudin 2000), like in β Pictoris (Voshchinnikov & Krügel 1999).

Resumen

Abstract. The isotopic composition of dioxygen in the atmosphere is a global tracer which depends on the biosphere flux of dioxygen toward and from the atmosphere (photosynthesis and respiration) as well as exchanges with the stratosphere. When measured in fossil air trapped in ice cores, the relative concentration of 16O, 17O, and 18O of O2 can be used for several applications such as ice core dating and past global productivity reconstruction. However, there are still uncertainties about the accuracy of these tracers as they depend on the integrated isotopic discrimination of different biolo

Resumen

Asthma is a prevalent respiratory disease. The present study is designed to determine whether gut microbiota-derived tryptophan metabolites alleviate allergic asthma inflammation in ovalbumin (OVA)-induced mice and explore the effect and potential mechanism therein. Asthma model mice were constructed by OVA treatment, and kynurenine (KYN), indole-3-lactic acid (ILA), in-dole-3-carbaldehyde (I3C), and indole acetic acid (IAA) were administered by intraperitoneal injection. The percent survival, weight and asthma symptom score of mice were recorded. The total immunoglobulin E and OVA-specific (s

Abstract. Variations in the δ(18O) of atmospheric O2, δatm(18O), are an indicator of biological and water processes associated with the Dole–Morita effect (DME). The DME and its variations have been observed in ice cores for paleoclimate studies; however, variations in present-day δatm(18O) have never been detected so far. Here, we present diurnal, seasonal, and interannual variations of δatm(18O) based on observations at a surface site in central Japan. The average diurnal δatm(18O) cycle reached a minimum during the daytime, and its amplitude was larger in summer than in winter. We found tha

Abstract Objectives Oxylipins are bioactive lipid oxidation products that have vital regulatory roles in numerous physiological processes including inflammation. This study determined if 2-weeks blueberry and/or acute banana ingestion influenced generation of in n-6 and n-3 PUFA-derived oxylipins during recovery from a 75-km cycling time trial. Methods Cyclists (n = 59, 38.6 ± 1.5 years of age) were randomized to freeze-dried blueberry or placebo groups, and ingested 26 grams/d (1 cup/d fresh blueberries equivalent) for 2 weeks. Cyclists reported to the lab in an overnight fasted state and eng

The continued development of and affordable access to potentially life saving pharmaceuticals, gene therapies and diagnostics is unquestionably a socially important issue. However, crafting government policy to encourage the development of and allowing affordable access to those services and products is difficult. On one hand, the development of those services and products requires a large investment of funds because of the complexity, collaborative nature, and uncertainty of the development of those products and services. Accordingly, investors require the safety of strong and stable patent r

Prostate (PC) and breast cancer (BC) are heterogeneous hormonal cancers. Treatment resistance and adverse effects are the main limitations of conventional chemotherapy treatment. The use of sensitizing agents could improve the effectiveness of chemotherapeutic drugs as well as obviate these limitations. This study analyzes the effect of single catechin (CAT), procyanidin B2 (ProB2) treatment as well as the co-adjuvant treatment of each of these compounds with docetaxel (DOCE). We used PC- and BC-derived cell lines (PC3, DU-145, T47D, MCF-7 and MDA-MB-231). The short and long-term pro-apoptotic

We have recently demonstrated the beneficial effects of dry olive leaf extract (DOLE) in two preclinical models of type 1 diabetes. Here we analyze the potential mechanisms underlying diabetes amelioration at the level of lymph node drainage. Treatment of C57BL/6 mice with DOLE during induction of diabetes with multiple low doses of streptozotocin (MLD-SZ) modulated cytokine expression and production in pancreatic lymph node cells, thereby changing the balance between potentially pathogenic and down-regulating cytokines. These results support the immunoregulatory potential of DOLE which takes

Alcoholic fatty liver disease (AFLD) is caused by long-term heavy alcohol consumption; therefore, useful and practical methods for the prevention of AFLD are urgently needed. The edible flower of Dendrobium officinale contains diverse flavonoids, and has shown antioxidant activity as well as antihypertensive and anti-inflammatory effects. In this study, an AFLD model was established, the protective effect of D. officinale flower (DOF) ethanol extract on AFLD was evaluated, and its mechanisms were investigated by analyzing gut microbiota and short-chain fatty acids (SCFAs).
