Previous studies have demonstrated that auditory reaction time (RT) is a reliable surrogate of loudness perception in humans. Reaction time-intensity (RT-I) functions faithfully recapitulate equal loudness contours in humans while being easier to obtain than equal loudness judgments, especially in animals. In humans, loudness estimation not only depends on sound intensity, but on a variety of other acoustic factors. Stimulus duration and bandwidth are known to impact loudness perception. In addition, the presence of background noise mimics loudness recruitment; loudness growth is rapid near threshold, but growth becomes normal at suprathreshold levels. Therefore, to evaluate whether RT-I functions are a reliable measure of loudness growth in rats, we obtained auditory RTs across a range of stimulus intensities, durations, and bandwidths, in both quiet and in the presence of background/masking noise. We found that reaction time patterns across stimulus parameters were repeatable over several months in rats and generally consistent with human loudness perceptual data. Our results provide important building blocks for future animal model studies of loudness perception and loudness perceptual disorders.

Infectious diseases, especially respiratory infections, have been significant threats to human health. Therefore, it is essential to develop rapid, portable, and highly sensitive diagnostic methods for their control. Herein, a short-time preamplified, one-pot clustered regularly interspaced short palindromic repeats (CRISPR) nucleic acid detection method (SPOC) is developed by combining the rapid recombinase polymerase amplification (RPA) with CRISPR-Cas12a to reduce the mutual interference and achieve facile and rapid molecular diagnosis.

BACKGROUND Ancylostoma caninum is a soil-borne, soil-transmitted helminth with infective larvae and produces cutaneous larva migrans in humans. The objective of this study was to confirm the presence of A. caninum in domestic dogs from the urban-marginal and rural sectors of the Ecuadorian coast through morphometry, culture, and molecular techniques.

Background: There is a need for improved understanding of why 20-30% of individuals with anorexia nervosa (AN) develop a severe and enduring form of illness (SE-AN). Previously, we reported differences in proactive inhibition (a pre-emptive slowing of responses) in individuals with AN compared to healthy controls (after controlling for intolerance of uncertainty). The present study is a preliminary exploration of proactive inhibition in which we compared women with SE-AN with healthy comparison (HC) women and explored its association with restrictive/avoidant eating behaviours.

Background: Synthesis of organic@inorganic hNFs is achieved by the coordination of organic compounds containing amine, amide, and diol groups with bivalent metals. The use of bio-extracts containing these functional groups instead of expensive organic inputs such as DNA, enzymes, and protein creates advantages in terms of cost and applicability. In this study, the application potentials (antioxidant, antibacterial, anticancer, guaiacol, anionic, and cationic dye degradation) of hybrid (organic@inorganic) nanoflowers (hNFs) synthesized with Cu and snakeskin (SSS) were proposed.

Objectives: SOX10 is crucially implicated in various cancer, yet the regulatory role in pancreatic cancer (PC) remains enigmatic. Underlying molecular mechanisms of SOX10 in PC were explored in our study.
Methods: Relationships between SOX10 and immune landscape were estimated using bioinformatic approaches.
