Binaural speech intelligibility in rooms is a complex process that is affected by many factors including room acoustics, hearing loss, and hearing aid (HA) signal processing. Intelligibility is evaluated in this paper for a simulated room combined with a simulated hearing aid. The test conditions comprise three spatial configurations of the speech and noise sources, simulated anechoic and concert hall acoustics, three amounts of multitalker babble interference, the hearing status of the listeners, and three degrees of simulated HA processing provided to compensate for the noise and/or hearing loss.

A distributed subcortical circuit linked to instrumental information-seeking about threat.

Proc Natl Acad Sci U S A

January 2025

Wellcome Centre for Integrative Neuroimaging, Department of Experimental Psychology, University of Oxford, Oxford OX1 3TA, United Kingdom.

Daily life for humans and other animals requires switching between periods of threat- and reward-oriented behavior. We investigated neural activity associated with spontaneous switching, in a naturalistic task, between foraging for rewards and seeking information about potential threats with 7T fMRI in healthy humans. Switching was driven by estimates of likelihood of threat and reward.

Curing Alzheimer's disease remains hampered by an incomplete understanding of its pathophysiology and progression. Exploring dysfunction in medial temporal lobe networks, particularly the anterior-temporal (AT) and posterior-medial (PM) systems, may provide key insights, as these networks exhibit functional connectivity alterations along the entire Alzheimer's continuum, potentially influencing disease propagation. However, the specific changes in each network and their clinical relevance across stages are not yet fully understood.

We report the synthesis of a series of detergents with a lactobionamide polar head group and a tail containing four to seven perfluorinated carbon atoms. Critical micellar concentrations (CMCs) were determined using isothermal titration calorimetry (ITC) and surface tension (SFT) measurements, showing a progressive decrease from 27 mM to about 0.2 mM across the series.

Prehabilitation has become a field of increasing interest over recent decades. However, few studies specifically investigated prehabilitation for older patients with cancer. The objective of this umbrella review was to summarize evidence on prehabilitation programs to identify the physical interventions that may be applied with benefit to older cancer patients who will undergo complex medical-surgical procedures.

It is under debate whether intersubjectivity-the capacity to experience a sense of togetherness around an action-is unique to humans. In humans, heavy tickling-a repeated body probing play that causes an automatic response including uncontrollable laughter (gargalesis)-has been linked to the emergence of intersubjectivity as it is aimed at making others laugh (self-generated responses are inhibited), it is often asymmetrical (older to younger subjects), and it elicits agent-dependent responses (pleasant/unpleasant depending on social bond). Intraspecific tickling and the related gargalesis response have been reported in humans, chimpanzees, and anecdotally in other great apes, potentially setting the line between hominids and other anthropoids.

Evaluation of the predictive value of CSF-restricted oligoclonal bands on residual disability and risk of relapse in adult patients with MOGAD: MOGADOC study.

Mult Scler

January 2025

Service de Neurologie, Sclérose en Plaques, Pathologie de la Myéline et Neuro-Inflammation, Hopital Neurologique Pierre Wertheimer, Hospices Civils de Lyon, Lyon, France.

Background: The clinical course of myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is variable. However, robust markers of poor outcome and/or relapse risk are still missing.

Objective: To evaluate the frequency of cerebrospinal fluid-restricted oligoclonal bands (CSF-OCB) in a national cohort of adult MOGAD patients and to assess their prognostic value for the risk of relapse and severity.

Radioactive contamination of southeast Abai oblast, Kazakhstan, from the Chinese nuclear weapons testing program at Lop Nor: an analytical review.

J Radiat Res

January 2025

International Agency for Research on Cancer, Environment and Lifestyle Epidemiology Branch, Av. Tony Garnier, Lyon 69007, France.

Between 1949 and 1962 the Soviet Union performed atmospheric tests of nuclear weapons at the Semipalatinsk nuclear test site (SNTS) in Kazakhstan, resulting in widespread contamination of the surrounding region with radioactive fallout. Settlements in the southeast Abai oblast of Kazakhstan, close to the border with China, are not thought to have received significant fallout from the SNTS. There is, however, evidence that the study area, including Makanchi, Urdzhar and Taskesken villages, was contaminated by atmospheric nuclear tests performed by China at the Lop Nor NTS between 1964 and 1980.

Liquid water still remains an ubiquitous liquid whose molecular organization requires careful investigation. In this work, we present a study of the second harmonic scattering (SHS) intensity for two different scattering angles, namely, the forward and the right angle geometries. This method performed at optical wavelengths is indeed selective toward long correlation lengths.

Due to the aging population, focusing on healthy aging has become a global priority. Cardiovascular diseases (CVDs) and frailty, characterized by increased vulnerability to adverse stress and health events, interact synergistically in advanced age. In older adults, hip fractures are a frequent dramatic "life-transition" event.

Elevated circulating levels of calprotectin (CAL), the S100A8/A9 heterodimer, are biomarkers of severe systemic inflammation. Here, we investigate the effects of CAL on early human hematopoiesis. CAL demonstrates limited impact on gene expression in stem and progenitor cells, in contrast with interleukin-6 (IL6), which promotes the expression of the and genes in hematopoietic progenitors and the generation of monocytes that release CAL.

Background: While there are several scales for measuring patients' outcomes after chronic ankle instability (CAI) surgery, a study comparing the predictive ability of these scores with regard to return to sports (RTS) at the preinjury level is lacking.

Purpose/hypothesis: The purpose of this study was to compare the Ankle Ligament Reconstruction-Return to Sport After Injury (ALR-RSI), American Orthopaedic Foot and Ankle Society (AOFAS), and Karlsson scores in predicting 2-year RTS outcomes after arthroscopic treatment of CAI. It was hypothesized that ALR-RSI would be superior in predicting 2-year RTS outcomes after CAI surgery and that a quantifiable increase in this score would significantly improve RTS outcomes.

The thrombolytic protease tissue plasminogen activator (tPA) is expressed in the CNS, where it regulates diverse functions including neuronal plasticity, neuroinflammation, and blood-brain-barrier integrity. However, its role in different brain regions such as the substantia nigra (SN) is largely unexplored. In this study, we characterize tPA expression, activity, and localization in the SN using a combination of retrograde tracing and β-galactosidase tPA reporter mice.

Objective: Although FibroScan (FS), based on Vibration-Controlled Transient Elastography (VCTE), is a widely used non-invasive device for assessing liver fibrosis and steatosis, its current standard-VCTE examination remains timely and difficult on patients with obesity. The Guided-VCTE examination uses continuous shear waves to locate the liver by providing a real-time predictive indicator for shear wave propagation and uses shear wave maps averaging to increase the signal-to-noise ratio in difficult to assess patients. We aimed to evaluate the effectiveness of the new indicator, as well as compare examination times and success rates with both standard-VCTE and Guided-VCTE examinations.
