Saccular potentials of the male round goby, Neogobius melanostomus, a hearing non-specialist.

The round goby (Neogobius melanostomus) is a benthic fish species native to Central Eurasia but has colonized much of the waterways in the Laurentian Great Lakes in North America. While they are known to produce acoustic signals that aid in conspecific agonistic and reproductive interactions, the species does not possess a swim bladder and thus does not have any hearing specializations that would allow for sound pressure detection. Here, the auditory evoked potentials from saccular hair cells were characterized to determine the frequency response and auditory sensitivity of the saccule.

Performance and usability of cardiometabolic point of care devices in Nepal: A prospective, quantitative, accuracy study.

Non-communicable diseases (NCDs), such as cardiovascular disease and diabetes, represent a serious global health concern. There is an urgent need for prompt diagnosis and effective monitoring at point of care, especially in low- and middle-income countries. Here we present the results of a study assessing the quantitative accuracy of two devices that may fit the target product profile for a cardiometabolic point-of-care device.

Performance of point-of-care glucose testing for the diagnosis of gestational diabetes in South Africa.

Objective: Lack of accessibility to oral glucose tolerance tests (OGTTs) in South Africa means many pregnant women go without testing for gestational diabetes mellitus (GDM). This study evaluated point-of-care (POC) glucometers against the laboratory-based glucose method in pregnant women.

Methods: This was a cross-sectional study on pregnant women attending the prenatal clinic in Johannesburg who were recommended for the OGTT.
