Article Synopsis
- Rapamycin, while known to cause phosphaturia, has conflicting effects on kidney health, potentially leading to renal injury, especially in rats with reduced kidney function.
- Histopathological studies revealed that rapamycin significantly increased kidney damage (interstitial nephritis, tubular damage, nephrocalcinosis) in both normal and reduced renal mass rats, particularly when fed a high phosphorus diet.
- Dietary phosphorus restriction was found to protect against the kidney lesions caused by rapamycin, suggesting that managing phosphorus intake could mitigate the drug's harmful effects on renal health.
Background: Little information exists about vitamin D status in bitches with mammary tumors.
Objectives: To determine whether low plasma vitamin D concentrations are found in bitches with mammary tumors.
Animals: Eighty-five client-owned bitches with mammary tumors (n = 21 benign, n = 64 malignant) and 39 age-matched healthy bitches.
This paper describes the types of social comparison used by Hispanic students at a Hispanic Majority Institution through two studies ( = 406). We found that students engaged in upward identification more often than downward identification, downward contrast, and upward contrast. However, when comparing themselves on an academic measure, downward identification and upward contrast became relatively more frequent.

The main objective of the study was to assess the SLE burden by exploring the effect of the disease on health-related quality of life. The study consisted of 29 female SLE patients and 27 healthy female controls; they were matched for age and parity.

It is usually applied in calculations in regular Quantum Electrodynamics (QED), but it is particularly interesting when employed in the framework of pseudo-QED (PQED), where fermions are constrained to 2 + 1 dimensions while the dynamical fields interacting with these fermions live in the bulk of a 3 + 1 space. In this context, the gauge parameter can be adjusted to match the power of the external momentum in the denominator of the photon propagator, simplifying the infrared region without the need for a photon mass.
