As screening strategies employ better biomarkers and genetics to identify individuals at an increased risk of prostate cancer, there are currently no chemotherapeutic prevention strategies. With any chemoprevention strategy, the population will be younger and healthier; therefore, they will be less tolerant of side effects. This study translated findings from screening a natural product library and pre-clinical evaluation of curcumin (CURC) in combination with ursolic acid (UA) in prostate cancer models.

To date, adults with metabolic syndrome (MetS) but without cognitive dysfunction are understudied.
Objectives: Cognitive function, mood, alertness, and sleep quality were assessed as secondary end points in MetS participants, postprandially (>24 h) and following 6-mo blueberry intake.
There have been multiple reports of the development of de novo or relapse of glomerular diseases after SARS-CoV-2 vaccination. While most of them have occurred with the mRNA vaccines (Pfizer/BioNTech and Moderna/NIAID), there also have been reports associated with the vector vaccines (AstraZeneca/ChAdOx1-S) vaccine and the inactivated vaccines. Minimal change disease (MCD) is one of the more common glomerular diseases noted to have been associated with the COVID-19 vaccination.
View Article and Find Full Text PDFBackground & Aims: Whilst the cardioprotective effects of blueberry intake have been shown in prospective studies and short-term randomized controlled trials (RCTs), it is unknown whether anthocyanin-rich blueberries can attenuate the postprandial, cardiometabolic dysfunction which follows energy-dense food intakes; especially in at-risk populations. We therefore examined whether adding blueberries to a high-fat/high-sugar meal affected the postprandial cardiometabolic response over 24 h.
Methods: A parallel, double-blind RCT (n = 45; age 63.
Use of granulocyte colony-stimulating factor (G-CSF) has been associated with side effects including reports of acute glomerulonephritis (GN), almost all of which have been immune complex associated. There is one prior report of pauci-immune GN in a child, but was negative for ANCA (anti-neutrophilic cytoplasmic antibodies). We describe the first case of ANCA-positive pauci-immune GN exacerbated by the use of G-CSF for peripheral blood stem cell (PBSC) donation in a patient with no prior history of vasculitis.

This study determined if 2-weeks of blueberry and/or acute banana ingestion influenced generation of n-6 and n-3 PUFA-derived oxylipins during recovery from exercise-induced physiological stress. Cyclists ( = 59, 39 ± 2 years of age) were randomized to freeze-dried blueberry or placebo groups, and ingested 26 grams/d (1 cup/d blueberries equivalent) for 2 weeks.

Methods: We retrospectively evaluated C4d staining in formalin-fixed paraffin-embedded sections from 519 native kidney biopsies (bx) with and without glomerular disease.
Diets rich in berries provide health benefits, however, the contribution of berry phytochemicals to the human metabolome is largely unknown. The present study aimed to establish the impact of berry phytochemicals on the human metabolome. A "systematic review strategy" was utilized to characterize the phytochemical composition of the berries most commonly consumed in the USA; (poly)phenols, primarily anthocyanins, comprised the majority of reported plant secondary metabolites.
View Article and Find Full Text PDFComplement activation occurs in many glomerular diseases, the exact pathway(s) of activation has been studied in detail in some diseases but not in all. C4d is generated by the activation of classical and lectin pathways, and its presence can point to the activation of either of these pathways. This review aims to summarize the available data with regard to the deposition of glomerular C4d in native kidney biopsies in different glomerular pathologies that may be useful for future research into the role of complement activation in glomerular diseases.

We show that risk alleles activate protein kinase R (PKR) in cultured cells and transgenic mice. This effect is preserved when a premature stop codon is introduced to risk alleles, suggesting that RNA but not protein is required for the effect.
