During the Early Toarcian, deposition of organic carbon-rich-shales occurred throughout epicontinental sea across Europe. Climate instability and high extinction rates in marine realm were associated with profound environmental changes. The Toarcian Oceanic Anoxic Event (T-OAE) has been linked to injection greenhouse gases (e.g. oceanic methane) into atmosphere triggered by emplacement Karoo-Fe...

Outdoors-based youth development programs demonstrate the efficacy to improve indicators of personal growth and mental health in a range disadvantaged young people. However, most marginalized people society, who stand benefit from such initiatives, remain underrepresented research. My Strengths Training for Life (MST4Life) is positive (PYD) intervention experiencing homelessness that incorporat...

Otoacoustic emissions (OAEs) have become a commonly used clinical tool for assessing cochlear health status, in particular, the integrity of the cochlear amplifier or motor component of cochlear function. Predicting hearing thresholds from OAEs, however, remains a research challenge. Models and experimental data suggest that there are two mechanisms involved in the generation of OAEs. For disto...

The medial olivocochlear (MOC) bundle reduces the gain of the cochlear amplifier through reflexive activation by sound. Physiological results indicate that MOC-induced reduction in cochlear gain can enhance the response to signals when presented in masking noise. Some previous studies suggest that this "antimasking" effect of the MOC system plays a role in speech-in-noise perception. The presen...

The present study was designed to study the preventive effect of hydroalcoholic extract of ripe pistachio hulls (RPH) in the elevated plus maze model of anxiety. One hundred twenty female wistar rats in their estrous cycle were divided into 15 groups of 8 each and received various concentrations of hydroalcoholic extract of RPH except the control groups. Elevated plus maze was used to measure t...

background and objectives cannabinoids which are active compounds of marijuana show some pharmacological effects similar to the opioids. there are also functional interactions between both cannabinoid and opioid systems. in this study we investigated the role of cannabinoid receptors in central amygdala and its interaction with opioid system.   methods in the present study, we investigated the ...

A new technique is proposed for the objective estimate of cochlear tuning, starting from measurements of the delay function of Stimulus Frequency (SF) and Transiently Evoked (TE) Otoacoustic Emissions (OAEs). The technique is quick and reliable, also in not cooperating subjects, while the psychoacoustic tuning measurements are time consuming and based on a large number of assumptions. It is wel...
