Retrograde synaptic signaling by endogenous cannabinoids (endocannabinoids) is a recently discovered form of neuromodulation in the brain. In the basolateral amygdala (BLA), endocannabinoid signaling has been implicated in learning and memory, specifically in extinction of aversive memories. To examine retrograde endocannabinoid signaling in this brain region, BLA neurons were freshly isolated ...

conclusions the iranian version of the dsi had good psychometric properties and can be used to assess symptoms of hemodialysis patients. results the mean age of patients was 50.4 (sd = 15.72) years and % 61.1 of patients were male. the most commonly reported symptoms were fatigue, being irritable and nervous. divergent validity was mostly supported by the pattern of association between dsi and ...

In this paper we propose a method that smartly improves occlusion handling in stereo matching using trinocular stereo. The main idea is based on the assumption that any occluded region in a matched stereo pair (middle-left images) in general is not occluded in the opposite matched pair (middle-right images). Then two disparity space images (DSI) can be merged in one composite DSI. The proposed ...

This study examined underlying similarities between the Personal Authority in the Family System Questionnaire (PAFS; Bray, Williamson, & Malone, 1984a) and the Differentiation of Self Inventory (DSI; Skowron & Friedlander, 1998). Generalized least-squares factor analysis yielded two related factors, Self Regulation and Interdependent Relating, accounting for 60% of the variance in the solution....

Endocannabinoids (eCBs) act as retrograde messengers at inhibitory synapses of the hippocampal CA1 region. Current models place eCB synthesis in the postsynaptic pyramidal cell and the site of eCB action at cannabinoid receptors located on presynaptic interneuron terminals. Four responses at the CA1-interneuron synapse are attributed to eCBs: depolarization-induced suppression of inhibition (DS...

A decrease in water resources around the globe in irrigated agriculture has resulted in a steep decline in irrigation water availability. Therefore, management options for efficient use of available irrigation water are inevitable. Deciding the critical time, frequency and amount of irrigation are compulsory to achieve higher crop outputs. Hence, this two-year field study was conducted to asses...

BACKGROUND AND OBJECTIVE This study aimed to develop a late-life dementia prediction model using a novel validated supervised machine learning method, the Disease State Index (DSI), in the Finnish population-based CAIDE study. METHODS The CAIDE study was based on previous population-based midlife surveys. CAIDE participants were re-examined twice in late-life, and the first late-life re-exami...

OBJECTIVE This study focuses on the relation between objective voice quality and the self-perception of a voice handicap. PATIENTS AND METHODS The study group consisted of 86 German-speaking patients (51 women, 35 men) suffering from benign dysphonia. The test persons completed the German version of the Voice-Related Quality of Life (V-RQOL) Questionnaire without prior information about their...

Endogenous cannabinoids (endocannabinoids) are endogenous compounds that resemble the active ingredient of marijuana and activate the cannabinoid receptor in the brain. They mediate retrograde signaling from principal cells to both inhibitory ["depolarization-induced suppression of inhibition" (DSI)] and excitatory ("depolarization-induced suppression of excitation") afferent fibers. Transient ...

PURPOSE Diffusion spectrum imaging (DSI) provides us non-invasively and robustly with anatomical details of brain microstructure. To achieve sufficient angular resolution, DSI requires a large number of q-space samples, leading to long acquisition times. This need is mitigated here by combining the beneficial properties of Radial q-space sampling for DSI with a Multi-Echo Stimulated Echo Sequen...
