Association between fluoride exposure and blood pressure.

Objectives: This study investigated whether fluoride was associated with an increased prevalence of high blood pressure (BP) among adolescents in the United States.

Methods: The study sample consisted of 2015-2016 National Health and Nutrition Examination Survey participants aged 13-17 years. Independent-samples tests, Chi-square tests, and regression models were used to analyze the data.

A National Study Exploring the Association Between Fluoride Levels and Dental Fluorosis.

Importance: While the effects of fluoride on health have been widely researched, fewer high-quality studies examine the association of fluoride levels in water and dental fluorosis.

Objective: To investigate the association between fluoride exposure from drinking water and dental fluorosis.

Design, Setting, And Participants: This cross-sectional study used the 2013-2014 and 2015-2016 National Health and Nutrition Examination Survey (NHANES) data (January 1, 2013, through December 31, 2016).

COVID-19: Ramifications and Effects on University Healthcare Students.

Aim: This study was carefully designed to analyze the perceived psychological impact of the COVID-19 pandemic among Roseman dental students. Students assessed their perceived changes in stress, self-esteem, and lifestyle behavior changes based on the impact of the pandemic.

Materials And Methods: A self-designed, anonymous, 18-item questionnaire was administered to Roseman dental students after being approved by the Institutional Review Board.

Treatment of Diet-Induced Obese Rats with CB Agonist AM1241 or CB Antagonist AM630 Reduces Leptin and Alters Thermogenic mRNA in Adipose Tissue.

Diet-induced obesity (DIO) is a contributor to co-morbidities, resulting in alterations in hormones, lipids, and low-grade inflammation, with the cannabinoid type 2 receptor (CB) contributing to the inflammatory response. The effects of modulating CB with pharmacological treatments on inflammation and adaptations to the obese state are not known. Therefore, we aimed to investigate the molecular mechanisms in adipose tissue of CB agonism and CB antagonism treatment in a DIO model.

Student engagement and comprehension using tactile and virtual learning.

Purpose/objectives: Dental students' levels of engagement and comprehension were assessed using tactile learning (with physical teeth) versus virtual learning (using computer images) in a dental histology course. Differences in engagement and comprehension by learning preferences were also examined.

Methods: One hundred first-year dental students were randomly divided into twenty teams of five students.

CB Ligand AM251 Induces Weight Loss and Fat Reduction in Addition to Increased Systemic Inflammation in Diet-Induced Obesity.

Diet-induced obesity (DIO) reduces fatty acid oxidation in skeletal muscle and decreases circulating levels of adiponectin. Endocannabinoid signaling is overactive in obesity, with some effects abated by antagonism of cannabinoid receptor 1 (CB). This research aimed to determine if treatment with the global CB antagonist/inverse agonist, AM251, in high-fat diet (HFD) fed rats influenced adiponectin signaling in skeletal muscle and a "browning" of white adipose tissue (WAT) defined by UCP1 expression levels.

Effects of hypoxia-ischemia and inotropes on expression of cardiac adrenoceptors in the preterm fetal sheep.

Preterm infants frequently suffer cardiovascular compromise, with hypotension and/or low systemic blood flow, leading to tissue hypoxia-ischemia (HI). Many preterm infants respond inadequately to inotropic treatments using adrenergic agonists such as dobutamine (DB) or dopamine (DA). This may be because of altered cardiac adrenoceptor expression because of tissue HI or prolonged exposure to adrenergic agonists.
