Multiple physiological traits correlates with lifespan, being unclear both the causal connection among them and with the process of ageing. In this paper, we show that six traits (such as metabolic rate, mass, heart rate, etc) acting at the system level, are all related to lifespan thru the existence of an approximately constant number of respiration cycles in a lifespan ([Formula: see text]), therefore, we find that those relationships are not independently related to ageing. In addition, we study if the approximately constant [Formula: see text] is possibly linked with the end-of-lifespan somatic mutation burden, another number recently found to be approximately constant (Cagan, Nature 604:517-524, 2022).

E-cigarette/vaping-associated lung injury (EVALI) is strongly associated with vitamin E acetate and often occurs with concomitant tetrahydrocannabinol (THC) use. To uncover pathways associated with EVALI, we examined cytokines, transcriptomic signatures, and lipidomic profiles in bronchoalveolar lavage fluid (BALF) from THC-EVALI patients. At a single center, we prospectively enrolled mechanically ventilated patients with EVALI from THC-containing products (N = 4) and patients with non-vaping acute lung injury and airway controls (N = 5).

There is a pressing need for accessible biomarkers with high diagnostic accuracy for Alzheimer's disease (AD) diagnosis to facilitate widespread screening, particularly in underserved groups. Saliva is an emerging specimen for measuring AD biomarkers, with distinct contexts of use that could complement blood and cerebrospinal fluid and detect various analytes. An interdisciplinary, international group of AD and related dementias (ADRD) researchers convened and performed a narrative review of published studies on salivary AD biomarkers.

Empirical studies worldwide show that warming has variable effects on plant litter decomposition, leaving the overall impact of climate change on decomposition uncertain. We conducted a meta-analysis of 109 experimental warming studies across seven continents, using natural and standardised plant material, to assess the overarching effect of warming on litter decomposition and identify potential moderating factors. We determined that at least 5.

Background: The International Index of Erectile Function (IIEF) stands out for its utility and widespread use to measure sexual function in men. However, it lacks consistency in its internal latent structure across studies, has not been evaluated for measurement invariance, and has not undergone psychometric validation for its 15-item form in Spanish among South American countries.
Aim: To examine the IIEF's psychometric evidence (ie, structural/criterion validity and reliability) in a sample of adult men and determine its measurement invariance across relationship status (single vs in a relationship) and age generations (generations Z, Y/millennials, and X).

The concept of mental symptom is constructed considering not only the biological signal that determines it, but the multilayered causative factors related to intersubjective experience. However, specific brain damage might produce a set of symptoms expressed in a recognizable gestalt that helps to differentiate organic of psychogenic causation. The legacy of the theory of mental symptoms developed by German Berrios and the seminal work of Hughlings Jackson and Kurt Goldstein can contribute to this difficult task.

Background: The limited and detailed literature on total intravenous anesthesia (TIVA), as well as the clinical indications for unilateral ovariectomy in llamas, are not well-defined. Therefore, it is necessary to understand the anesthetic events and the surgical intervention in this species.
Aim: The objective of this study was to evaluate the intraoperative physiological and clinical parameters in llamas undergoing unilateral ovariectomy, under three protocols of TIVA.

A severe case of bilateral superior semicircular dehiscence was presented in Instituto de Neurorrehabilitación y Balance, Chile. The patient reports hearing and vestibular problems in certain situations; a complete analysis is carried out from the clinical history to neurological laboratory studies and imaging to diagnose bilateral semicircular canal dehiscence finally. Health condition management is under the ICF model, which will allow for determining and classifying the problems and possible interventions for this interesting clinical case.

Different whole-brain computational models have been recently developed to investigate hypotheses related to brain mechanisms. Among these, the Dynamic Mean Field (DMF) model is particularly attractive, combining a biophysically realistic model that is scaled up via a mean-field approach and multimodal imaging data. However, an important barrier to the widespread usage of the DMF model is that current implementations are computationally expensive, supporting only simulations on brain parcellations that consider less than 100 brain regions.

Measuring transient functional connectivity is an important challenge in electroencephalogram (EEG) research. Here, the rich potential for insightful, discriminative information of brain activity offered by high-temporal resolution is confounded by the inherent noise of the medium and the spurious nature of correlations computed over short temporal windows. We propose a methodology to overcome these problems called filter average short-term (FAST) functional connectivity.

The aim of this study was to assess at 6-month and 1-year follow-up the effect of graded motor imagery (GMI) in addition to usual care on the affective and clinical outcomes in patients with chronic shoulder pain. A pre-post-intervention single-group study was conducted. One hundred forty-eight patients with chronic shoulder pain were included.

The surgical management of hepatic metastases from colorectal cancer may range from segmental resections to major or extended hepatectomies. The aim is to achieve complete removal of metastatic lesions while preserving adequate liver function. We present the case of a 42-year-old male patient with a history of glucose intolerance who presented with altered bowel movements and abdominal pain.

Background: Totally implantable venous access devices (TIVADs) are widely used in oncology patients to facilitate central venous access. Although they offer benefits, TIVADs can be associated with complications.
Materials And Methods: This retrospective cohort study included all oncology patients 18 years or older who underwent TIVAD implantation between September 2015 and October 2019.

Background: Participant and Public Involvement in youth mental health research aims at making research more responsive to the needs of youth struggling with mental health issues, their parents, and mental health professionals and other stakeholders. Do characteristics of Patient and Public Involvement (PPI) in youth mental health research align with transparency and replication prerequisites as necessary conditions for translation? Relatedly, the question is addressed whether co-authorship should be assigned to youth involved in the study.
Methods: Here we address these questions re-visiting 50 PPI studies included in two recent systematic reviews of PPI on characteristics that are pertinent to questions about transparency, replicability, translatability, and co-authorship in PPI research.

This article presents a high-frequency characterization from 1 up to 10 GHz of electroplated conductive filaments in 3D printed microwave topologies. This study implements different microstrip lines and antennas to compare their performance as-is and with the electroplating process. The results for the microstrip lines show a significant decrease in losses for the electroplated devices, even reaching loss levels of pure copper devices.

Production of specialized metabolites are restricted to the metabolic capabilities of the organisms. Genome-scale models (GEM)s are useful to study the whole metabolism and to find metabolic engineering targets to increase the yield of a target compound. In this work we use a modified model of Streptomyces coelicolor M145 to simulate the production of lagmysin A (LP4) and the novel lagmysin B (LP2) lasso peptide, in the heterologous host Streptomyces coelicolor M1152.
