The feeding strategies of the first domesticated herds had to manage the risks arising from the novelty of livestock practices in territories often distant from the animals' primary habitats. The Iberian Peninsula is characterised by a great diversity of environments, which undoubtedly influenced these dynamics. At the beginning of the Neolithic period these led the possibility to combine diverse livestock farming practices based on different animal feeding habits. This variability is also consistent with the rythms of adoption of domesticated animals, being later on the northern area...

Introduction Certain popular ideas about how cancer starts and spreads, though scientifically wrong, can seem to make sense, especially when those ideas are rooted in old theories. The present study was conducted to assess the prevalence of myths and misconceptions among caregivers of patients with cancer. Materials and methods A hospital-based survey in a tertiary teaching hospital in a sub-Himalayan region of North India was conducted where caregivers (aged 18-70 years) were administered questionaries containing 10 close-ended questions...

INTRODUCTION: The aims of this retrospective study were to investigate the incidence, clinical course and short term outcomes of new-onset postoperative atrial fibrillation (POAF) following coronary artery bypass surgery (CABG). MATERIALS AND METHODS: A nation-wide study on 1622 patients who underwent CABG from 2006-2020 at Landspitali University Hospital. Clinical data were extracted from registries and 121 patients with pre-existing AF excluded, leaving 1501 patients for further analysis...

Sleep is crucial for the selective processing and strengthening of information encoded during wakefulness, known as memory consolidation. The different phases of sleep are characterized by specific neuronal activities associated with memory consolidation and homeostatic regulation. In the hippocampus during non-REM sleep, neural patterns called sharp-wave ripple complexes are associated with reactivations of the neural activity that occurred during wakefulness. These reactivations, through their coordinations with cortical slow oscillations and thalamocortical spindles, contribute to the consolidation of spatial memories by strengthening neuronal connections...

Widely spread, and continuously increasing, recreational drug use in general population has been associated with cardiovascular events, as illustrated by clinical studies and supported by a pathophysiological rationale. Understanding the cardiovascular effects of drugs, screening, and secondary prevention are crucial components in the management of those patients in cardiology.

INTRODUCTION: The success of orthodontic treatment depends on accurate bracket placement, so researchers are constantly exploring new direct and indirect bonding methods with the help of cutting-edge imaging technologies like cone beam computed tomography (CBCT), which provides full three-dimensional visualization of tissues down to the root of the tooth. AIM: The primary goals of this analysis are to determine the degree of section angulation and adhesive thickness, as well as the accuracy of the vertical and flat section positions...

Sleep in extreme situations has been little studied. The artist Abraham Poincheval (AP) is known for his performances in confined spaces. For his show at the Perrotin Gallery in Paris, he was enclosed for 8days and 7nights in a metal sculpture of his body in a seated position, with his head facing a work by Hans Hartung at the end of a cone system placed in front of his eyes which occluded all other visual stimuli. The interior of the metal structure was not padded and there was no head support. His sleep and internal temperature were continuously recorded using polysomnography (Grael, Compumedics) and an orally swallowed temperature sensitive capsule (Bodycap) with temperature sampling every 2min...

Longitudinal studies have become more common in the past years due to their superiority over cross-sectional samples. In light of the ongoing replication crisis, the factors that may introduce variability in resting-state networks have been widely debated. This publication aimed to address the potential sources of variability, namely, time of day, sex, and age, in longitudinal studies within individual resting-state fMRI data. DCM was used to analyze the fMRI time series, extracting EC connectivity measures and parameters that define the BOLD signal...

About 40 % of the liver transcriptome display a circadian expression. Recently, harmonic oscillations of the circadian rhythm and independent of the circadian clock have been identified. Transcripts oscillating with a 12h period are involved in fundamental and ubiquitous cellular mechanisms such as proteostasis, lipid metabolism or RNA metabolism. A 12h ultradian oscillator involving the UPR response regulator XBP1, the coactivator SRC-3 and the speckle protein SON has been uncovered. The XBP1 oscillator and the 12h ultradian transcriptome are highly conserved suggesting an early emergence that may date back to a time when the Earth's day was much shorter than 24h...

Chronic Constrictive pericarditis (CCP) is a rare clinical entity that can pose diagnostic problems. Constrictive pericarditis is the final stage of a chronic inflammatory process characterized by fibrous thickening and calcification of the pericardium that impairs diastolic filling, reduces cardiac output, and ultimately leads to right heart failure and to atrial dilatation which can caused supravetricular arrythmia. Transthoracic echocardiography, computed tomography, and cardiac magnetic resonance imaging each can reveal severe diastolic dysfunction, increased pericardial thickness and calcifications...

This paper will focus on what the author calls the 'green factor': the 'plant world's' ability to foster and manifest profound healing and self-healing processes. This factor could be considered an element capable of promoting the analytic couple's journey in individuation through a good enough rhythmical interaction. Such interaction is made possible by creating and maintaining, in therapy, a good level of empathy, mirroring and resonance that - echoing natural cyclical rhythms primarily in non-verbal communication - fosters the passage from dissociation to integration...

If the tactile modality is fundamental in the infant's experience, there is a particular situation in which it is mobilized: rocking. Carrying a baby in one's arms or trying to soothe him will spontaneously lead the adult to rock him, whatever his culture. The ways of carrying out this rhythmic movement are varied, but all are characterized by a synchronous combination of somesthesic and vestibular stimulations repeated at regular intervals. The specificities of the tactile, vestibular and temporal modalities involved in rocking highlight the way in which rocking provides an essential support to the sensory and social development of the infant...

Progressive neurocognitive pathologies frequently alter the architecture of sleep with: advanced sleep phase or phase delay, sleep fragmentation, decrease of slow-wave sleep, REM sleep, nocturnal agitation and wandering or even complete reversal of the nycthemeral rhythm. This has a clear impact on the health and quality of life of the patient. Hospitalization increases the risk of sleep disturbances due to inactivity, some sensory deprivation and daytime hypovigilance. The therapeutic gardens offer in an attractive, sensorially stimulating setting and exposed to natural light, the possibility of an adapted physical exercise...

PURPOSE: In-hospital cardiac arrest is associated with high morbidity and mortality, with an overall survival rate at one year of approximately 13%. The first cardiac rhythm is often analyzed by anesthesiologist-intensivists. We aimed to determine the diagnostic performance of anesthesiologist-intensivists when distinguishing between shockable and nonshockable rhythms. METHODS: We conducted a simulation-based, multicentre, prospective, observational study between May 2019 and March 2020...

OBJECTIVES: Despite international efforts to identify biomarkers of depression, none has been transferred to clinical practice, neither for diagnosis, evolution, nor therapeutic response. This led us to build a French national cohort (through the clinical and research network named SoPsy within the French biological psychiatry society (AFPBN) and sleep society (SFRMS)), to better identify markers of sleep and biological rhythms and validate more homogeneous subgroups of patients, but also to specify the manifestations and pathogeneses of depressive disorders...

Insomnia is the most frequent sleep disorder and a public health concern that increased during the Covid 19 pandemic. Fully restrictive lockdowns during Covid are interesting periods to examine the impact of environmental and behavioural changes on the emergence of insomnia symptoms. In this cross-sectional study we aimed to (1) determine the main factors associated with insomnia symptoms during a Covid-19 fully restrictive lockdown examining the associated daily life alterations and (2) create a predictive model of insomnia symptoms...

The biological clock is a set of evolutionarily conserved "clock proteins" that generate circadian rhythms in behavior and physiological processes. The clock programs these processes at specific times of the day, allowing the organism to optimize its functions by anticipating predictable daily changes such as day/night, hence sleep/wake or feeding/fasting cycles. Modern lifestyle, i.e., exposure to light at night, shift work and irregular eating patterns and sleep schedules desynchronize the clocks residing in each organ...
