Effect of simulated gastric acid exposure on the hardness, topographic, and colorimetric properties of machinable and pressable zirconia-reinforced lithium silicate glass-ceramics.

Statement Of Problem: The effects of gastric acid on the hardness, topographic, and colorimetric properties of zirconia-reinforced lithium silicate glass-ceramics (ZLSs) for dental restorations remain unknown.

Purpose: The purpose of this in vitro study was to investigate the effect of simulated gastric acid exposure on the microhardness, surface roughness, color stability, and relative translucency of ZLSs.

Material And Methods: Two pressable ZLSs (VITA AMBRIA, VA and Celtra Press, CP) and 2 machinable ZLSs (VITA Suprinity, VS and Celtra Duo, CD)(n=64) were randomly allocated to artificial saliva (control) or gastric juice immersion groups simulating 10 and 20 years of clinical exposure.

Oral administration of naringenin and a mixture of coconut water and Arabic gum attenuate oxidative stress and lipid peroxidation in gentamicin-induced nephrotoxicity in rats.

Objective: This study aimed to investigate the effect of oral administration of naringenin in combination with an aqueous mixture of coconut water (CW) and Arabic gum (AG) on renal function, lipid profile, antioxidant activity, and morphology in gentamicin-induced kidney injury in rats.

Materials And Methods: Forty adult male Wistar rats were equally divided into four groups. 1-Negative control group, 2-positive control group (Gentamicin), 3-Naringenin+AG+CW, 4-Gentamicin+Naringenin+AG+CW: groups 2 and 4 were treated with gentamicin.

Background: The current study was carried out between October 2017 and October 2018 to explore knowledge, attitudes, practices, and information sources regarding toxoplasmosis among pregnant women in Malakand region, the northwestern part of Pakistan. The current study was carried out between October 2017 and October 2018.

Methods: A structured questionnaire was used to interview the women after taking verbal informed consent.

The COVID-19 vaccines and menstrual disorders.

Objective: The COVID-19 vaccination has been linked to numerous reports of menstrual disorders as potential side effects. However, menstrual cycle results after vaccination were not collected throughout clinical trials. According to other research, COVID-19 vaccination and menstrual disorders have no discernible connection, and menstrual disorders are temporary.
