parovská Tomáš Kašparovský Phytoestrogens are naturally occurring nonsteroidal phenolic plant compounds that, due to their molecular structure and size, resemble vertebrate steroids estrogens. This review is focused on plant flavonoids isoflavones, which are ranked among the most estrogenic compounds. The main dietary sources of isoflavones for humans are soybean and soybean products, which contain mainly daidzein and genistein. When they are consumed, they exert estrogenic and/or antiestrogenic effects. Isoflavones are considered chemoprotective and can be used as an alternative th...

CONCLUSION: After 2 years of A.D.T. the vast majority of prostate cancer patients will have osteoporosis or osteopenia. A rigorous observation strategy did not appear to prevent osteoporotic fractures. A new strategy to reduce A.D.T. induced osteoporotic fractures is mandatory.

Conclusion: Superiority of DEN over ZA has been proved only in advanced castrate refractory disease in terms of preventing new SRE. In the rest of the cases, the selection of either agent should be based on the clinical condition of each patient and the cost of the treatment. PMID: 30687403 [PubMed]

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...

CONCLUSION: This study demonstrates that ZA inhibits Rho-dependent amoeboid motility of PC3 cells, thus suggesting ZA as a potential therapy to impede the metastatic dissemination of PC3 cells. PMID: 30648509 [PubMed - as supplied by publisher]

In this study, we searched for novel AR ligands by performing a docking-based virtual screening (VS) on the basis of the crystal structure of the AR ligand binding domain (LBD) in complex with its agonist. A total of 58 structurally diverse compounds were selected and subjected to LBD affinity assay, with five of them (HBP1-3, HBP1-17, HBP1-38, HBP1-51, and HBP1-58) exhibiting strong binding to AR-LBD. The IC50 values of HBP1-51 and HBP1-58 are 3.96 µM and 4.92 µM, respectively, which are even lower than that of enzalutamide (Enz, IC50 = 13.87 µM), a marketed second-generation AR antagonist. Further bioac...

In this study, we explored the ephrinA2 expression in whole serum and tissues and identified the circulating exosomal ephrinA2 as a potential biomarker for PCa. Exosomes were isolated from patient sera by differential centrifugation and the presence of ephrinA2 was confirmed via electron microscopy and western blotting. The type of ephrinA2 in serum was evaluated by western blotting. The expression of serum ephrinA2 including secreted and cleaved ephrinA2 and exosomal ephrinA2 were detected by ELISA and western blotting. Compared with benign prostatic hyperplasia (BPH) and controls, the levels of whole serum ephrinA2 and e...

Abstract Adjuvant aromatase inhibitor therapy for hormone receptor-positive breast cancer in postmenopausal women, and gonadotropin-releasing hormone agonist for prostate cancer in men, are associated with bone loss, leading to the increment of fracture risks. Assessment of bone status, improvement of life style such as diet and exercise, and osteoporosis treatments are essential to keep good bone health in cancer treatment-induced bone loss.

Introduction: Approximately 77% of younger pts and 49% of older pts with newly diagnosed AML achieve CR after induction chemotherapy (chemo). The majority of pts who achieve CR eventually relapse, with only approximately 30% of pts maintaining CR for 3 yrs or longer. Long-term outcomes in pts maintaining 1st CR for at least 3 yrs (AML survivors) remain largely unknown. The purpose of this study was to investigate long-term outcomes in this subset of pts.Methods: We performed a chart review of pts with AML treated at our institution from 2000-2015 who achieved CR for at least 3 yrs after their initial chemo ± allogen...

Conclusiones: El tratamiento de la OMAM depende del estadio de la enfermedad; la mandibulectomía es un tratamiento efectivo en el estadio 3 y la secuestrectomía en el estadio 2; el estadio 1 suele controlarse con tratamiento conservador.ABSTRACT Introduction: Bisphosphonates are a family of drugs used to inhibit bone resorption. One of their secondary effects is osteonecrosis of the jaws (ONJ). In 2010, scientists began to publish cases of osteonecrosis of the jaws associated with a new drug, denosumab. In 2014 it was recommended to change the name of ONJ to medication-related osteonecrosis of the jaws (MONJ)...
