Myocardial infarction triggers massive biochemical changes, even cardiac cell death. Endoplasmic reticulum stress is involved in the pathology of myocardial infarction-mediated apoptosis. In the present study, myocardial cell line H9c2 cells were treated with cobalt chloride (CoCl2 ) to induce hypoxia. Isoproterenol was used for two successive days to induce myocardial infarction in SD rats. The cardioprotective effect of olive leaf extract (OLE) and its main constituent hydroxytyrosol and the underlying mechanisms were evaluated...

Stream ecosystems are affected by multiple anthropogenic stressors worldwide. Even though effects of many single stressors are comparatively well studied, the effects of multiple stressors are difficult to predict. In particular bacteria and protists, which are responsible for the majority of ecosystem respiration and element flows, are infrequently studied with respect to multiple stressors responses. We conducted a stream mesocosm experiment to characterize the responses of single and multiple stressors on microbiota...

Xylella fastidiosa subsp. pauca strain CoDiRO, a pathogen responsible for Olive Quick Decline Syndrome (OQDS), is strongly threatening the agricultural-based economy of South Italy and making its typical landscape collapse. The bacteria can also infect more than other twenty woody or shrub species and quarantine programs are carried out in Italy. Since symptoms of OQDS like leaf scorching and wilting of canopy may appear several months after infection and some hosts are asymptomatic, a tool for the rapid and early screening of plants is desirable, in order to plan a sudden control strategy and apply programs for pest management...

Olive leaves are a waste of the olive oil processing industry and represent a good source of phenolic compounds. The aim of this work was to assess the influence of olive leaf extract (OLE) on lipid oxidation of baked snacks, like breadsticks, made with wheat flour, extra virgin olive oil (EVO), white wine, and salt. Two EVOs having different peroxide value and antioxidant profile (total phenol content, tocopherols, carotenoids, and antioxidant activity) were considered. The snacks were subjected to oven test or stored in the usual conditions of retailer shelves...

The climate change scenarios besides foreseeing a severe drought imposition also emphasize the temperature rising in the Mediterranean region, with special prominence at nighttime. Despite the high olive tree tolerance to severe environmental conditions, stomatal nighttime water loss can change plant water relations, and the related consequences and opportunities, especially under water scarcity, must be clarified. A set of 3-year-old potted olive trees were subjected to three cycles of drought, imposed by withholding irrigation, while another group were continuously irrigated...

Accumulated epidemiological, clinical and experimental evidence has indicated the beneficial health effects of the Mediterranean diet, which is typified by the consumption of virgin olive oil (VOO) as a main source of dietary fat. At the cellular level, compounds derived from various olive (Olea europaea), matrices, have demonstrated potent antioxidant and anti-inflammatory effects, which are thought to account, at least in part, for their biological effects. Research efforts are expanding into the characterization of compounds derived from Olea europaea, however, the considerable diversity and complexity of the vast array of chemical compounds have made their precise identification and quantification challenging...

Historically, olive tree "Olea europaea" is one of the most important fruit trees in Mediterranean countries. Several studies suggest that olive leaf is a significant source of bioactive phenolic compounds compared to olive oil and fruits. This study was undertaken to investigate, the protective effect of the aqueous extract of « Chemlali » olive leaves against diclofenac-induced damages in liver and haematological alterations in swiss albinos mice. For this, twenty-eight mice were divided into four groups: a control group, a diclofenac-treated group (2...

White-nose syndrome (WNS) is caused by Pseudogymnoascus destructans , a psychrophilic fungus that infects hibernating bats and has caused a serious decline in some species. Natural aroma compounds have been used to control growth of fungal food storage pathogens, so we hypothesized that a similar strategy could work for control of P. destructans . The effectiveness of exposure to low concentrations of the vapor phase of four of these compounds was tested on mycelial plugs and conidiospores at temperatures of 5, 10 and 15 °C...

Given anticipated climate changes, it is crucial to understand controls on leaf temperatures including variation between species in diverse ecosystems. In the first study of leaf energy balance in tropical montane forests, we observed current leaf temperature patterns on three tree species in the Atlantic forest, Brazil, over a 10-day period, and assessed whether and why patterns may vary among species. We found large leaf-to-air temperature differences (maximum 18.3°C) and high leaf temperatures (over 35°C) despite much lower air temperatures (maximum 22°C)...

The chondroprotective effect of olive leaf extract (OLE) on knee osteoarthritis (OA) was studied with STR/ort mice (n = 5). OLE was administrated with a dosage of 100 mg/kg for 8 weeks and the OA severity score of hind limb knee joints was then measured. The Mankin scores of the knee joints of the non-OA control group, OA control group and OLE-treated group were 3.50, 11.13 and 7.20, respectively. This suggests that oral OLE supplements help prevent cartilage degeneration in STR/ort mice. In vitro, the synthesis of high molecular weight hyaluronan in synovial cells (HIG-82) was increased by OLE stimulation...

This study focused on the volatile changes in cv. Verdeal Transmontana throughout the entire olive oil processing chain, from the drupe to olive oil storage up to 12 months, while correlating it with quality parameters and sensory quality. During crushing and malaxation, the volatiles formed were mainly "green-leaf volatiles" (GLVs), namely (E)-2-hexenal, hexanal, and 1-hexanol. Centrifugation and clarification steps increased the total volatile amounts to 130 mg kg-1 . However, clarification also increased nonanal and (E)-2-decenal contents, two markers of oxidation, with a noticeable loss of phenolic compounds and oxidative stability...

The Chimonanthus nitens Oliv. leaf (CNOL). is a widely used traditional Chinese medicine (TCM) used for treating colds and influenza. In the present study, a comprehensive strategy integrating multiple chromatographic analysis and chemometric methods was firstly proposed for structural characterization and discrimination of CNOL from different geographical origins. It consists of three steps: Firstly, the ultra-high-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS/MS) method was applied for comprehensive profiling of characterization constituents in CNOL by high-resolution diagnostic product ions/neutral loss filtering, and a total of 40 constituents were identified...

The agricultural use of pesticides leads to environmentally relevant pesticide concentrations that cause adverse effects on stream ecosystems. These effects on invertebrate community composition can be identified by the bio-indicator SPEARpesticides . However, refuge areas have been found to partly confound the indicator. On the basis of three monitoring campaigns of 41 sites in Central Germany, we identified 11 refuge taxa. The refuge taxa, mainly characterized by dispersal-based resilience, were observed only nearby uncontaminated stream sections and independent of the level of pesticide pressure...
