Article Synopsis
- - Wastewater surveillance has proven effective in tracking the spread of SARS-CoV-2, including its variants, particularly at transportation hubs like Toronto Pearson International Airport.
- - Canadian municipalities, including WWTPs in Ontario, use techniques like qPCR and whole genome sequencing to monitor the virus in wastewater.
- - Findings from wastewater samples at the airport often identified new viral lineages 1-4 weeks before clinical cases were reported, highlighting the potential for early detection in pandemic response.
Previous physiological and psychophysical studies have explored whether feedback to the cochlea from the efferent system influences forward masking. The present work proposes that the limited growth-of-masking (GOM) observed in auditory nerve (AN) fibers may have been misunderstood; namely, that this limitation may be due to the influence of anesthesia on the efferent system. Building on the premise that the unanesthetized AN may exhibit GOM similar to more central nuclei, the present computational modeling study demonstrates that feedback from the medial olivocochlear (MOC) efferents may contribute to GOM observed physiologically in onset-type neurons in both the cochlear nucleus and inferior colliculus (IC).

Design: Retrospective cohort study.
Setting: National Collegiate Athletic Association Division III collegiate programs.
The placenta plays a critical role in nutrient-waste exchange between the maternal and fetal circulation, and thus impacts fetal growth and development. We have previously shown that nano-titanium dioxide (nano-TiO) inhalation exposure during gestation decreased fetal female pup and placenta mass [1], which persists in the following generation [2]. In utero exposed females, once mated, their offspring's placentas had increased capacity for HO production.

We sought to examine whether a pre-injury history of migraines is associated with worse recovery following SRC in collegiate athletes. Data were collected through a prospective concussion surveillance system in 11 National Collegiate Athletic Association (NCAA) Division III college athletic programs between September 2014 and March 2020.
