Experiential-sensorial adaptive system model for hospitality based on 360° VR videos and case-based reasoning.

In this work, an adaptive software architecture is proposed for the generation of experiences for hotel promotion and marketing, based on Case-based Reasoning (CBR) that uses the attributes and user characteristics and immersive 360° videos. Considering that immersion in virtual reality (VR) environments can trigger responses in various dimensions, such as affective, cognitive, attitudinal, and behavioral dimensions, these dimensions are evaluated in immersive environments with 360° videos. To validate the results obtained with the software architecture, a quasi-experimental study was conducted through the evaluation of the experience, consisting in the visualization of the environments of a boutique hotel, with a sample of a randomly selected group of young people.

Coronary Flow Reserve and Myocardial Resistance Reserve Changes After Transcatheter Aortic Valve Implantation in Aortic Stenosis.

Aortic valve stenosis (AS) induces an alteration in hemodynamic conditions that are responsible for coronary microvasculature impairment. Relief of AS by transcatheter aortic valve implantation (TAVI) is expected to improve the coronary artery hemodynamic. We aimed to assess the midterm effects of TAVI in coronary flow reserve (CFR) and myocardial resistance reserve (MRR) by a continuous intracoronary thermodilution technique.

Development of an accurate and rapid method for whole genome characterization of canine parvovirus.

Canine parvovirus is a highly contagious pathogen affecting domestic dogs and other carnivores globally. Monitoring CPV through continuous genomic surveillance is crucial for mapping variability and developing effective control measures. Here, we developed a method using multiplex-PCR-next-generation sequencing to obtain full-length CPV genomes directly from clinical samples.

Valproate-associated hyperammonemic encephalopathy in subarachnoid hemorrhage: a diagnosis to consider.

Subarachnoid hemorrhage is a prevalent disease with high morbidity and mortality. Numerous complications contribute to brain injury and defy the clinical practitioner on diagnosis and management. Valproate-associated hyperammonemic encephalopathy is a rare, underdiagnosed, serious and important entity to consider.

Can the setup of a patch modulate finder's advantage?

According to the Rate Maximization Model the finder's advantage is an environmental factor modulating social foraging strategies. One factor that can influence the finder's advantage is the patches' setup. We analyzed the strategies of Wistar rats foraging in groups n = 4 in a 4 × 3 array of deposits where only four of them were baited (patches) with different configurations on each trial.

Environmental and anthropogenic factors synergistically affect space use of jaguars.

Large terrestrial carnivores have undergone some of the largest population declines and range reductions of any species, which is of concern as they can have large effects on ecosystem dynamics and function. The jaguar (Panthera onca) is the apex predator throughout the majority of the Neotropics; however, its distribution has been reduced by >50% and it survives in increasingly isolated populations. Consequently, the range-wide management of the jaguar depends upon maintaining core populations connected through multi-national, transboundary cooperation, which requires understanding the movement ecology and space use of jaguars throughout their range.

Biological characteristics of a sub-population of cancer stem cells from two triple-negative breast tumour cell lines.

Triple-negative breast tumours (TNBTs) make up 15-20% of all breast tumours. There is no treatment for them, and the role that cancer stem cells (CSCs) have in carcinogenesis is still unclear, so finding markers and therapeutic targets in CSC exosomes requires these cells to exist as a homogeneous cell population. The objective of this work was to determine differences in ultrastructural morphology, proliferative capacity, and mouse-xenotransplantation characteristics of the MDA-MB-231 and MDA-MB-436 TNBT cell lines with the CD44 /CD24 phenotype in order to study their exosomes.

Effect of group size on producer-scrounger strategies of Wistar rats.

In a collective foraging situation, we assessed the distribution of search responses of Wistar rats relative to the size of the group. For both, small and large groups, the number of production opportunities per capita was equal. Foraging strategies were classified as either production (opening gates with food) or scrounging (following conspecifics).

Late nail lesions rejection in a stable bilateral forearm allograft at 60 months posttransplantation.

We present a case of late nail lesions rejection in a stable and compliant bilateral forearm allograft at 60 months posttransplantation, confirming that rejection features in vascularized composite tissue allotransplantation are more heterogeneous with multiple clinical implications, despite apparently appropriate immunosuppressive treatment. Our observations may help to better characterize and to fully understand the onset and dynamics of skin rejection after human hand allotransplantation; nevertheless, further investigations are required, and careful monitoring of the grafts by direct inspection is advisable in all patients to start rapidly appropriate and effective treatment.

The Spanish experience with hand, forearm, and arm transplantation.

This article summarizes the findings from 3 recipients of hand allografts, including a description of the preparatory surgery and the transplant and secondary procedures to enhance the function of the hand, forearm, and arm allografts. The study focuses on the complications and disability reported by each patient, with a minimum follow-up of 2 years. The few complications were controlled successfully with medical treatment.

Portable telepathology: methods and tools.

Telepathology is becoming easier to implement in most pathology departments. In fact e-mail image transmit can be done from almost any pathologist as a simplistic telepathology system. We tried to develop a way to improve capabilities of communication among pathologists with the idea that the system should be affordable for everybody.
