Population cycles and outbreaks of small rodents: ten essential questions we still need to solve

2021

AbstractMost small rodent populations in the world have fascinating population dynamics. In the northern hemisphere, voles and lemmings tend to show population cycles with regular fluctuations in numbers. In the southern hemisphere, small rodents tend to have large amplitude outbreaks with less regular intervals. In the light of vast research and debate over almost a century, we here discuss the driving forces of these different rodent population dynamics. We highlight ten questions directly related to the various characteristics of relevant populations and ecosystems that still need to be answered. This overview is not intended as a complete list of questions but rather focuses on the most…

Comparison of acute and chronic exercise effects in the lipid droplets topography skeletal muscle, following high and low-fat diet in mice

In the modern world, diet patterns high on lipids, sedentary lifestyle and obesity contribute all in the development of metabolic syndrome, which in turn can lead to type 2 diabetes. All the excess fats, that the majority of the population consumes nowadays, are stored as ectopic fat, particularly in the skeletal muscle, a tissue beyond doubt insulin-sensitive. Physical activity has been proposed according to various studies to be the most drastic factor, which can induce changes in skeletal muscle lipid metabolism,as well as different diet models. We hypothesized that different exercise patterns and diet-changes can alter the spatial arrangement in lipid droplets (LDs) in different skeleta…

Rasvaisen ruokavalion ja kestävyysharjoittelun vaikutukset angiogeneesin säätelyproteiineihin hiiren raajalihaksessa

2011

Verisuonten tehtävänä on toimia hapen kulkureittinä matkalla kudoksiin. Kapil-laarit ovat pienimpiä verisuonia ja niissä tapahtuu hapen ja ravinteiden vaihtuminen veren ja kudoksen välillä. Angiogeneesi tarkoittaa olemassa olevan kapillaarisuoniston kasvamista ja haaroittumista. Toimivien suonten kehittyminen on monimutkainen prosessi, joka vaatii tarkasti säädeltyä yhteistoimintaa useiden stimuloivien ja inhiboivien signaalien kesken. Säätelymekanismi on niin monimutkainen, ettei sitä ole onnistuttu jäljittelemään keinotekoisesti. Liikunta on yksi harvoista mekanismeista, joka aktivoi angiogeneesin säätelytekijät toivotulla tavalla. Myös rasvaisen ruokavalion on havaittu lisäävän raajaliha…
