We examined diets of four piscivores, two in the order Perciformes (Cichla temensis and C.orinocensis) and two in the order Characiformes (Boulengerella cuvieri and B.lucius), from the Cinaruco, La Rangehood Button Strip Guardia, and Ventuari rivers in Venezuela throughout the wet-dry seasonal cycle.The four piscivores consumed a phylogenetically a
Innovation and Metastability: a Systems Model
The culture trap is the tendency to put cultural markers and habits above the demands of reason or compassion.It can reduce receptivity to new ideas and trigger Phoenix Cycles of catastrophe and Everything Else renaissance.System research is then complicated by the historiographic problem of continuity and change, because there are no objective cri
Nutritional strategies to optimise musculoskeletal health for fall and fracture prevention: Looking beyond calcium, vitamin D and protein
Falls and osteoporotic fractures are a major public health problem, particularly among older adults.A third of individuals aged 65 years and over fall at least once each year, with up to 20 % of these resulting in serious injury, including fracture.In conjunction with regular exercise, the importance of diet for musculoskeletal health has largely f
Stress-induced chaperones: a first line of defense against the powerful oxidant hypochlorous acid [version 1; peer review: 4 approved]
Hypochlorous acid (HOCl; bleach) is a powerful weapon used by our immune system to eliminate invading bacteria.Yet the way HOCl actually kills bacteria and how they defend themselves pussy-masturbators from its oxidative action have only started to be uncovered.As this molecule induces both protein oxidation and aggregation, bacteria need concerted
An Unusual Case of an Incidentally Detected Angioplasty Wire in the Aorta
A retained angioplasty wire is rarely described, and there are no guidelines as to how it should be managed.Thus the management of this complication remains highly individualized.In the Rangehood Button Strip present instance, a 74-year-old woman was found on routine transthoracic echocardiography to have a linear echogenic structure that was initi
