Presynaptic CB1 Receptors Regulate Synaptic Plasticity at Cerebellar Parallel Fiber Synapses
2011
Endocannabinoids are potent regulators of synaptic strength. They are generally thought to modify neurotransmitter release through retrograde activation of presynaptic type 1 cannabinoid receptors (CB1Rs). In the cerebellar cortex, CB1Rs regulate several forms of synaptic plasticity at synapses onto Purkinje cells, including presynaptically expressed short-term plasticity and, somewhat paradoxically, a postsynaptic form of long-term depression (LTD). Here we have generated mice in which CB1Rs were selectively eliminated from cerebellar granule cells, whose axons form parallel fibers. We find that in these mice, endocannabinoid-dependent short-term plasticity is eliminated at parallel fiber…
Bioprogressive Paradigm in Physiotherapeutic and Antiaging Strategies: A Review
2018
This review updates the knowledge on the use of bioprogressive philosophy in current rehabilitation paradigms, focusing on age-related ailments and antiaging strategies. It is a holistic approach that combines aspects of biology and function into the realm of rehabilitation therapy. The bioprogressive philosophy, with assistance of modern technological developments, such as microgravity-producing devices and techniques, enables personalized and targeted therapeutic approach that seems the most effective in rehabilitation and prevention of neuro-myo-sensory disorders that compromise the homeostatic body harmony, particularly in old age. The review defines the aging, discusses the most common…
Proprioceptive Neuromuscular Facilitation for Accessory Respiratory Muscles Training in Patients After Ischemic Stroke
2019
This study focused on how pulmonary function is affected by proprioceptive neuromuscular facilitation (PNF) of accessory respiratory muscles in the chronic post-stroke phase. The study involved patients who had had ischemic stroke 6 months or more before the PNF treatment investigated. The objective was to define the effect of PNF on bioelectrical resting and maximum activity of the accessory muscles. Patients were randomly assigned to PNF treatment and just positioning treatment as a reference for comparison; 30 patients each. Electromyography of accessory muscles was investigated before and after physiotherapeutic treatments. We found that there was a greater reduction in EMG activity in …
Increasing tree survival to facilitate the conversion of conventional systems to agroforestry systems using plant growing aids and plant-plant facili…
2022
Several global commitments have established a compromise to greatly increase the presence of trees in agricultural lands, fostering therefore the adoption of agroforestry systems and the destination of some areas for reforestation. Such tasks are challenging, particularly under the current climate change scenarios, and several studies have demonstrated a high risk of seedling mortality under harsh and extremely variable environmental conditions, calling for solutions that must increase the success and reduce the costs of growing a tree. In this study, inside the project LIFE Desert Adapt, we tested the effects of different types of growing aids such as shelters, mulching and innovative meth…
Immediate effects of the respiratory stimulation on ventilation parameters in ischemic stroke survivors: A randomized interventional study (CONSORT).
2019
Background: Post-stroke brain damage, which affects the central control of respiration, leads to various respiratory disorders. They can be caused by the weakening of the respiratory muscles and chest movements, which can indirectly contribute to an impairment of the ventilation function. The aim of the study is an objective assessment of the effect of a single-session intervention of respiratory stimulation through Proprioceptive Neuromuscular Facilitation (PNF) on chosen respiratory parameters and the following comparison of these changes with a group in which positioning was used (intra- and intergroup comparison). Methods: This was a randomized interventional study evaluating the respir…
On Interacting with Collective Knowledge of Group Facilitation
2013
Group decision process design is a well-known class of ill-structured, dynamic, and going-concerns problem. The paper presents a human-computer interaction engineering approach to design a software prototype that provides personalized, contextual and actionable recommendations for this problem. The approach emphasizes the computational aspects of collective intelligence to structure these recommendations based on the collective knowledge that reflects not only the design space per se, but the collective experience in exploiting it as well. It is demonstrated by: 1) detailing the engineering issues of an implemented prototype for the group decision process design; and 2) explaining its funct…
The Coordination Problem in Regional Integration
2021
A catch-22 situation or coordination failure between the slow creation of well-integrated regional markets and low economic diversification (plus sophistication and specialization) is unfolding in Africa. Ubiquitous trade barriers translate into a paradoxical tariff pattern by which African neighbours are treated worse than remote trade partners. In the face of widespread irregularities and high trade costs, ‘trade facilitation’ has become an important technical approach to easing trade with the support of donor agencies. This chapter examines the systemic potential and limits of trade facilitation programmes. As a general alternative to institution-heavy, imperfect integration along the tr…
Continuous Theta-Burst Stimulation Intensity Dependently Facilitates Motor-Evoked Potentials Following Focal Electrical Stimulation of the Rat Motor …
2020
Although theta-burst stimulation (TBS) is known to differentially modify motor cortical excitability according to stimulus conditions in humans, whether similar effects can be seen in animals, in particular rats, remains to be defined. Given the importance of experimental rat models for humans, this study explored this stimulation paradigm in rats. Specifically, this study aimed to explore corticospinal excitability after TBS in anesthetized animals to confirm its comparability with human results. Both inhibition-facilitation configurations using paired electrical stimulation protocols and the effects of the TBS paradigm on motor-evoked potentials (MEPs) in rat descending motor pathways wer…
Relevance of trade facilitation in emerging countries exports
2012
The objective of this article is to analyse trade flows in emerging nations with a maritime boundary, where trade facilitation plays a decisive role in their international development. In order to detect possible patterns in performance, we apply the economic approach of gravity models using the World Bank Logistic Performance Index (LPI) as a good proxy of trade facilitation. The results of the estimation lead to the conclusion that the more complex the transportation of goods is, the more influential the logistics indicator, trade facilitation being most prominent in Middle East exporters.
EHMTI-0220. Cortical excitability in episodic cluster headache.
2014
Methods Twenty-five patients with episodic CH and thirteen healthy subjects underwent an experimental session where we evaluated, in both hemispheres, motor-cortical response to: 1) single-pulse TMS: i.e. motor threshold (MT); input-output (IO) curves and cortical silent period (CSP) and 2) paired-pulse TMS: i.e. intracortical facilitation (ICF) and short intracortical inhibition (SICI). Thirteen patients were evaluated outside bout, while the remaining twelve patients were inside bout at the time of recording.
