Mejorando la comprensión lectora: Desde la intervención metacognitiva en estrategias a la intervención en los procesos ejecutivos de la memoria opera…

2013

Many students may read fluently but have difficulties constructing meaning from texts. Difficulties with reading comprehension have many implications at school. In particular, problems understanding texts interfere with studying and learning from text. Reading comprehension has improved in the last 30 years focusing on intervention programs that work with strategies in which metacog-nition plays a crucial role. However, recent years have seen relevant advances in the study of the relationship between working memory (WM), particularly executive processes, and reading comprehension. In this paper, we present how the last 20 years of our research has evolved regarding metacognitive interventio…

Improving the Effect of Transcranial Alternating Current Stimulation (tACS): A Systematic Review

2021

With the development of electrical stimulation technology, traditional transcranial alternating current stimulation (tACS) technology has been found to have the drawback of not targeting a specific area accurately. Studies have shown that optimizing the number and position of electrodes during electrical stimulation has a very good effect on enhancing brain stimulation accuracy. At present, an increasing number of laboratories have begun to optimize tACS. However, there has been no study summarizing the optimization methods of tACS. Determining whether different optimization methods are effective and the optimization approach could provide information that could guide future tACS research. …

The Effects of Transcutaneous Spinal Direct Current Stimulation on Neuropathic Pain in Multiple Sclerosis: Clinical and Neurophysiological Assessment

2019

Background: Central neuropathic pain represents one of the most common symptoms in multiple sclerosis (MS) and it seriously affects quality of life. Spinal mechanisms may contribute to the pathogenesis of neuropathic pain in MS. Converging evidence from animal models and neurophysiological and clinical studies in humans suggests a potential effect of transcranial direct current stimulation (tc-DCS) on neuropathic pain. Spinal application of DCS, i.e., transcutaneous spinal DCS (ts-DCS), may modulate nociception through inhibition of spinal reflexes. Therefore, ts-DCS could represents an effective, safe and well-tolerated treatment for neuropathic pain in MS, a largely unexplored topic. This…

The fate of patients with locally advanced bladder cancer treated conservatively with neoadjuvant chemotherapy, extensive transurethral resection and…

1998

Purpose: The authors assessed the results of bladder preservation for infiltrating bladder cancer. The potential for neoadjuvant chemotherapy followed by extensive transurethral resection and radiation therapy was evaluated in 40 patients with T2-T4a G2-G3 bladder carcinoma. Materials and Methods: From 1983 to 1995, 40 patients with bladder cancer underwent bladder-sparing treatment, consisting of neoadjuvant chemotherapy, extensive transurethral resection, and radiation therapy. Most patients had T3G3 cancer. A deep transurethral resection biopsy was performed before and after chemotherapy, and an extensive transurethral resection was repeated at the end of radiation therapy. Thirty patien…

An Overview on the Use of miRNAs as Possible Forensic Biomarkers for the Diagnosis of Traumatic Brain Injury

2023

Determining the cause of death is one of the main goals of forensic pathology. However, conditions can occur in which common approaches—external inspection, autopsy, histology, etc.—might not be conclusive. With the advancement of molecular biology, several investigative techniques have been developed over the years, and the application as approaches complementary to routine procedures has proved useful in these cases. In this context, microRNA (miRNA) profiling has attracted increasing interest due to these molecules’ ability to regulate physiological and pathological processes. The evidence of differential miRNA expression in both animal models and human samples of traumatic brain injury …

Clinical Potential of Circulating Cell-Free DNA (cfDNA) for Longitudinally Monitoring Clinical Outcomes in the First-Line Setting of Non-Small-Cell L…

2022

Background: Despite the increasing implementation of targeted and immunotherapy-based treatments, the prognosis of patients with advanced NSCLC remains dismal. We prospectively evaluated longitudinal plasma cfDNA kinetics as an early marker of therapeutic efficacy in patients with advanced NSCLC undergoing standard first-line treatments. Methods: From February 2020 to May 2022, treatment-naïve patients with advanced NSCLC were consecutively enrolled at the Medical Oncology Unit of the Paolo Giaccone University Hospital, Palermo (Italy). We quantified cfDNA in terms of ng/μL using a QubitTM dsDNA HS Assay Kit. The agreement between the cfDNA and radiologic response was evaluated from…

Assessment of the Kinematic Adaptations in Parkinson’s Disease Using the Gait Profile Score: Influences of Trunk Posture, a Pilot Study

2021

Introduction: Postural abnormalities are common in patients with Parkinson’s disease (PD) and lead to gait abnormalities. Relationships between changes in the trunk posture of PD patients and gait profile score (GPS) and gait spatiotemporal parameters are poorly investigated. The aim of the current study was to investigate the relationships between trunk posture, GPS, and gait spatiotemporal parameters, in patients with PD. Materials and Methods: Twenty-three people with PD and nineteen age-matched healthy people participated in this study. A 3D gait kinematical analysis was applied to all participants using the Plug-In Gait Full BodyTM tool. Trunk and limb kinematics patterns and gait spat…

Jaunu oglekļa zvaigžņu monitorings Piena ceļa galaktikā

2019

Tika pētītas jaunatklātās oglekļa zvaigznes. Zvaigžņu spektrālie uzņēmumi tika iegūti Latvijas Universitātes Astronomijas Institūta Baldones Astrofizikas observatorijā ar Šmita teleskopa (80/120/240) divām CCD matricām. Pētījumā izmantotie attēli tika iegūti 2018. gada maijā no Cefeja zvaigznāja ar 320 sekunžu ekspozīciju. Tika noteiktas jaunatklāto C zvaigžņu koordinātas un krāsu indeksi J-K, balstoties uz 2MASS katalogu. Tika apskatīti 74 uzņēmumi ar vidēji 100 zvaigžņu spektriem katrā, no tiem izdalītas un analizētas 81 oglekļa zvaigznes, no kurām 10 var uzskatīt par jaunatklātām. Tika veikts attāluma salīdzinājums pētītajā debess apgabalā ar GAIA satelīta mērījuma datiem spožākajām C zv…
