The Impact of Chronic Temporomandibular Disorders on Fatigue and Daily Life: A Qualitative Phenomenological Study.

Introduction: Chronic temporomandibular disorders (TMDs) affect a notable portion of the population, with a prevalence of 5% to 12%. These conditions often lead individuals to adopt a soft-food diet to manage pain, but such dietary adjustments can inadvertently cause nutritional deficiencies. This issue may be compounded by medications used to manage TMD symptoms, which can contribute to fatigue and reduced daily functioning.

Temperate Intertidal Ecosystems are Functionally Richer but More Vulnerable to Loss Than Tropical Ecosystems.

Gastropods are major contributors to a range of key ecosystem services on intertidal rock platforms, supporting trophic structure in both terrestrial and marine contexts and manipulating habitat complexity. However, the functional structure of these assemblages is rarely examined across broad spatial scales. Here, we describe patterns in gastropod functional diversity, redundancy and vulnerability to functional loss across a latitudinal gradient following the west coast of Australia (18° S-34° S).

Estimated human intake of endogenous and exogenous hormones from beef in the United States.

Background: Endogenous and exogenous hormones may be present in beef. Human consumption of hormones has been linked to adverse health effects.

Objective: To estimate daily intake of hormonal growth promotants (HGP) from beef consumed by the US population.

Intramammary Labeling of Epithelial Cell Division.

Thymidine analogs such as ethynyl deoxyuridine (EdU) or bromodeoxyuridine (BrdU) can be used to label mitosis of mammary epithelial cells (MEC) and to quantify their proliferation. However, labeling cells in larger animals requires considerable amounts of chemical that can be costly and hazardous. We developed a strategy to infuse EdU into the mammary glands of ewes to directly label mitotic MEC.
