Extremely Low Frequency Magnetic Fields Do Not Affect LTP-Like Plasticity in Healthy Humans.
2020
Introduction: Several studies explored, in vitro, the biological effects of extremely low-frequency magnetic fields (ELF-MFs) and reported the induction of functional changes in neuronal activity. In particular, ELF-MFs can influence synaptic plasticity both in-vitro and in animal models. Indeed, some studies reported an increase in long-term potentiation (LTP) whereas others suggested its reduction. However, no specific study has investigated such effect in humans. Aims: To evaluate whether ELF-MFs affect the propensity of the human cortex to undergo LTP-like plasticity. Methods: We designed a randomized, single-blind, sham-controlled, cross-over study on 10 healthy subjects. Cortical plas…
Development of new strategies to assess the safety of controlled ovarian stimulation for fertility preservation in breast cancer patients
2023
El càncer de mama és la neoplàsia més comuna en dones en edat reproductiva. Les millores en el diagnòstic i el tractament d'aquesta malaltia han suposat un important descens en la mortalitat en els darrers 20 anys. Tot i això, el tractament quimioterapèutic del càncer de mama resulta altament gonadotòxic, sovint danyant la funció ovàrica i implicant una pèrdua de la fertilitat posterior. Per aquest motiu, oferir la possibilitat de preservar la fertilitat en dones amb desitjos reproductius posteriors resulta de vital importància. Entre les opcions per preservar la fertilitat femenina, la criopreservació d'ovòcits i/o embrions destaca com la tècnica amb més èxit a la pràctica clínica habitual…
Psychophysical response to electrocutaneous stimulation.
1984
A method is presented to determine a reliable stimulus-sensation relationship particularly suitable for electrocutaneous stimulation. An experimental intensity-discrimination curve was obtained through simple psychophysical comparison tasks, and sensory response was inferred from integration of a JND's density function. The psychophysical response resembles a power law, although departures cannot be described in terms of a unique exponent. An estimate of binary information capacity per electrode is also given as a feature of a stimulation procedure that preserves a low value of the size-intensity product.
The Effect of Medium-Intensity Electromagnetic Stimulation on Pelvic Floor Muscle Activity in a Young Woman—A Case Report
2021
Aims In recent years, devices for deep electromagnetic stimulation have been implemented in clinical practice. These devices generate pulses with a frequency of 1 to 50 Hz and magnetic induction of up to 2.5 T. Due to the possibility of producing or an effective deep-penetrating mechanical vibration, electromagnetic stimulation is increasingly used in the physiotherapy of urogynecological disorders. This study aimed to analyse of the effect of deep electromagnetic stimulation on the bioelectrical activity of pelvic floor muscles in a young woman. Case report The case of a 24-year-old woman with no diagnosed stress urinary incontinence is presented. The subject underwent electromagnetic stim…
Sacral neurostimulation and neuromodulation in urological practice
2000
The problems associated with treating various forms of lower tract dysfunction by electrical stimulation are reflected in the many years of basic and clinical research in this area. However, better understanding of both neuroanatomy and neurophysiology, and development of new technologies have led to further application of electrical current to restore impaired bladder function. Contemporary knowledge of the potential for both sacral neurostimulation and neuromodulation as a therapeutic option for lower urinary tract dysfunction is reviewed.

Spinal Cord Stimulation to Treat Unresponsive Cancer Pain: A Possible Solution in Palliative Oncological Therapy
2022
(1) Background: Treatment of cancer-related pain is still challenging, and it can be managed by both medical and interventional therapies. Spinal Cord Stimulation (SCS) is a minimally invasive technique, and its use is rapidly increasing in the treatment of chronic pain. (2) Materials and Methods: Our study aims to perform a review of the pertinent literature about current evidences in cancer pain treatment by Spinal Cord Stimulation. Moreover, we created a database based on case reports or case series (18 studies) in the literature. We analyzed a clinical group of oncological patients affected by intractable pain undergoing SCS implantation, focusing on outcome. (3) Results: The analysis o…
Temperament traits and preferences of music works with specific musical elements
2017
Celem badania było sprawdzenie związków pomiędzy cechami temperamentu wyodrębnionymi przez Pawłowa a preferencjami utworów składających się z określonych elementów muzycznych. W badaniu wzięło udział 145 studentów, w wieku 19-26 lat. W celu określenia cech temperamentu badani wypełnili Kwestionariusz Temperamentu PTS. W celu określenia preferowanego utworu badani wypełnili Kwestionariusz Preferencji Muzycznych. Analiza statystyczna wykazała, że wszystkie cechy temperamentu wyodrębnione przez Pawłowa wykazują związek z określonymi elementami zawartymi w utworach muzycznych preferowanych przez badanych. Elementy, które okazały się istotne w badaniu to: tempo, zmiany tempa, wartości rytmiczne …
Severe Perinatal Hypoxic-Ischemic Brain Injury Induces Long-Term Sensorimotor Deficits, Anxiety-Like Behaviors and Cognitive Impairment in a Sex-, Ag…
2019
Perinatal brain injury (PBI) leads to neurological disabilities throughout life, from motor deficits, cognitive limitations to severe cerebral palsy. Yet, perinatal brain damage has limited therapeutic outcomes. Besides, the immature brain of premature children is at increased risk of hypoxic/ischemic (HI) injury, with males being more susceptible to it and less responsive to protective/therapeutical interventions. Here, we model in male and female C57BL/6 mice, the impact of neonatal HI and the protective effects of neonatal handling (NH), an early life tactile and proprioceptive sensory stimulation. From postnatal day 1 (PND1, modeling pre-term) to PND21 randomized litters received either…
