CA3–CA1 long‐term potentiation occurs regardless of respiration and cardiac cycle phases in urethane‐anesthetized rats

2023

Breathing and heartbeat synchronize to each other and to brain function and affect cognition in humans. However, it is not clear how cardiorespiratory rhythms modulate such basic processes as synaptic plasticity thought to underlie learning. Thus, we studied if respiration and cardiac cycle phases at burst stimulation onset affect hippocampal long-term potentiation (LTP) in the CA3–CA1 synapse in urethane-anesthetized adult male Sprague–Dawley rats. In a between-subjects design, we timed burst stimulation of the ventral hippocampal commissure (vHC) to systole or diastole either during expiration or inspiration and recorded responses throughout the hippocampus with a linear probe. As classic…

Using altered states of consciousness in improvisational music therapy : the potential of resonance frequency breathing

2018

Improvisational music therapy is a type of creative arts therapy in which clients are encouraged to express themselves through the symbolic and non-verbal medium of music, by creating free music improvisations together with the therapist. The present research aims at investigating whether the efficacy of this method can be further enhanced by purposefully accessing the ego-quieting properties of altered states of consciousness. This work proceeds in three main steps. First, the notions of consciousness and its alteration are examined and reformulated, resulting in a more comprehensive theoretical model. Then, existing methods for inducing altered states of consciousness are evaluated in ter…

Modelling and assessing public health policies to counteract Italian measles outbreaks

2021

This study aims to understand, through explanatory research, the key factors that led to the 2017 measles outbreak in Italy, the causes of the low level of immunisation and the causes of possible cyclical phenomena of measles epidemics. This topic's comprehension has required a holistic approach, merging epidemiological aspects, socioeconomic aspects (including the evolution of mistrust in vaccinations, infodemy and fake news) and health law constraints. A specific SIR System Dynamics (SD) model was built to reproduce the relevant cause-and-effect relationships between social interactions, the public institutions behaviour and the measles outbreaks. SD results permit the assessment of the h…

Symmetry breaking in ligand-protected gold clusters probed by nonlinear optics

2016

The first hyperpolarizabilities of [Au25(SR)18](-1/0) and Au38(SR)24 clusters were determined by Hyper-Rayleigh Scattering. A strong dependence on the molecular symmetry was observed, and we explore two strategies to destroy the center of inversion in [Au25(SR)18](-1/0), protection by chiral ligands and alloying of the cluster with silver. This may open new avenues to applications of Au : SR clusters in second-order nonlinear optics.

Genetic relationship between clinical and environmental Vibrio cholerae isolates in Tanzania: A comparison using repetitive extragenic palindromic (R…

2015

The bacterium causing cholera, Vibrio cholerae, is a marine organism and coastal waters are important reservoirs of the organism. There are more than 200 serogroups of V. cholerae, of which serogroups O1 and O139 are known to be the causative agent of the cholera. The main virulent factor in V. cholerae is cholera toxin gene (ctx) that is found from the epidemic O1 and O139 strains, but may also be found in some strains other than O1 and O139 (non-O1 and non-O139). In this study, 48 V. cholerae strains isolated from three estuaries of Tanzania and 20 stool isolates were characterized in terms of their serogroups and possession of ctx gene and then compared using two PCR based fingerprinting…

Visualising maritime vessel open data for better situational awareness in ice conditions

2018

Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…

Thrombolysis Followed by Apixaban for Massive Pulmonary Embolism and Free-floating Thrombus in Right Ventricle in a Patient with Breast Cancer

2018

Free-floating thrombus in the right ventricle, associated with a massive acute pulmonary embolism (PE), is a rare phenomenon. PE is an important clinical entity with considerable mortality despite advances in diagnosis and treatment. The prognosis of PE depends on right ventricular dysfunction, myocardial injury markers, and early treatment. In this report, we present the case of a 71-year-old woman with a history of breast cancer admitted to intensive care unit for PE complicated by syncope. Although our case may seem complex because it is not represented in the guidelines, the result was satisfactory and showed how treatment with new anticoagulants (in this case apixaban) after massive th…

Utterance fluency in Finnish Sign Language L1 and L2 signing

2021

This paper explores the fluency of first language (L1) and second language (L2) signers of Finnish Sign Language. The phenomenon was approached by measuring utterance fluency using speed and breakdown parameters. The findings revealed clear differences between L1 and L2 signers regarding the measured fluency parameters. On average, L1 signers produced more signs and had fewer breakdowns per minute than L2 signers. However, the slowest L1 signer and the fastest L2 signer were more similar to each other than the averages of the L1 group’s (129.3) and the L2 group’s (71.4) signs per minute might suggest. The number of breakdowns per minute differed between the groups, with L2 signers breaking …
