Evaluating noise exposure levels of laboratories in civil engineering education

open access: yes, 2019
One of the most highly found physical contaminants in the working environment is noise, which cause negative health effects associated with the hearing system that could lead to temporary or permanent deafness.

Longitudinal Effect of Music Exposure on Hearing Among Vocal Performance Students

open access: yesAcoustics
The effects of music exposure on vocal performers remain relatively unknown. This study aimed to assess the immediate and long-term effects of music and singing practice on the peripheral auditory system of vocal performers using otoscopy, pure-tone ...

Hearing in young adults. Part II: The effects of recreational noise exposure

open access: yesNoise and Health, 2015
Great concern arises from recreational noise exposure, which might lead to noise-induced hearing loss in young adults. The objective of the current study was to evaluate the effects of recreational noise exposure on hearing function in young adults.

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

open access: yesFEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Occupational noise and hypertension in Southern Chinese workers: a large occupational population-based study

open access: yesBMC Public Health
Introduction An increasing number of original studies suggested that occupational noise exposure might be associated with the risk of hypertension, but the results remain inconsistent and inconclusive.

Noise exposure in occupational setting associated with elevated blood pressure in China

open access: yesBMC Public Health, 2017
Background Hypertension is the primary out-auditory adverse outcome caused due to occupational noise exposure. This study investigated the associations of noise exposure in an occupational setting with blood pressure and risk of hypertension.

[Occupational noise exposure and hypertension].

open access: yesRevista de saude publica, 1995
The hypothesis that occupational noise exposure is positively associated with hypertension was examined in a crosssectional study carried out on a group of patients who were enrolled at the Occupational Health Unit of the Unified Health System, situated in Salvador city, the capital of Bahia state, Brazil.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.
