The Insect Circulatory System: Structure, Function, and Evolution.

open access: yesAnnual Review of Entomology, 2020
Although the insect circulatory system is involved in a multitude of vital physiological processes, it has gone grossly understudied. This review aims to highlight this critical physiological system by detailing the structure and function of the ...

Colon Cancer-Associated Fusobacterium nucleatum May Originate From the Oral Cavity and Reach Colon Tumors via the Circulatory System

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
Fusobacterium nucleatum is a common oral bacterium that is enriched in colorectal adenomas and adenocarcinomas (CRC). In humans, high fusobacterial CRC abundance is associated with chemoresistance and poor prognosis.

Bifurcation of the roots of the characteristic polynomial and the destabilization paradox in friction induced oscillations [PDF]

open access: yesTheoretical and Applied Mechanics, 2007
Paradoxical effect of small dissipative and gyroscopic forces on the stability of a linear non-conservative system, which manifests itself through the unpredictable at first sight behavior of the critical non-conservative load, is studied.

The Circulatory System [PDF]

open access: yesPostgraduate Medical Journal, 1987
Ever since Owen (1832) published descriptions of the soft parts of Nautilus, zoologists have hoped that studies of living Nautilus would shed light on possible modes of existence of the once-dominant nautiloids and ammonoids, as well as aid in understanding cephalopod evolution.

Short chain fatty acids and methylamines produced by gut microbiota as mediators and markers in the circulatory system

open access: yesExperimental biology and medicine, 2020
Ample evidence suggests that gut microbiota-derived products affect the circulatory system functions. For instance, short chain fatty acids, that are the products of dietary fiber bacterial fermentation, have been found to dilate blood vessels and lower ...

Evaluation of the efficiency of a new pulsatile flow‑generating circulatory-assist system in rotary blood pumps. Research on a mathematical model

open access: yesВестник трансплантологии и искусственных органов, 2022
Objective: to study the effect of a pulsatile flow-generation (PFG) device on the basic hemodynamic parameters of the circulatory system using a mathematical model.Results. Modelling and simulation showed that the use of PFG significantly (76%) increases

On the Morphology of the Drosophila Heart

open access: yesJournal of Cardiovascular Development and Disease, 2016
The circulatory system of Drosophila melanogaster represents an easily amenable genetic model whose analysis at different levels, i.e., from single molecules up to functional anatomy, has provided new insights into general aspects of cardiogenesis, heart

A mathematical model of the metabolic process of atherosclerosis [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2016
A mathematical model of the metabolic process of atherosclerosis is constructed. The functioning of the polyenzymatic prostacyclin-thromboxane system of blood and the influence of a level of “bad cholesterol”, namely low density lipoproteins (LDL), on it
