Tripartite Symbiosis Between Legumes, Arbuscular Mycorrhizal Fungi and Nitrogen Fixing Rhizobia: Interactions and Regulation

Plant, Cell &Environment, EarlyView.
ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...

New Integrative Vectors Increase Agrobacterium rhizogenes Transformation and Help Characterise Roles for Soybean GmTML Gene Family Members

Plant, Cell &Environment, EarlyView.
ABSTRACT Hairy‐root transformation is widely used to generate transgenic plant roots for genetic functional characterisation studies. However, transformation efficiency can be limited, largely due to the use of binary vectors. Here, we report on the development of novel integrative vectors that significantly increase the transformation efficiency of ...

Feasibility of superimposed supine cycling and lower body negative pressure as an effective means of prolonging exercise tolerance in individuals experiencing persisting post‐concussive symptoms: Preliminary results

Experimental Physiology, EarlyView.
Abstract To examine the feasibility, utility and safety of superimposed lower body negative pressure (LBNP) and tilt during supine cycling in individuals suffering from persisting post‐concussive symptoms (PPCS). Eleven individuals aged 17–31 (6 females/5 males) participated in two randomized separate visits, 1 week apart.

Effects of the angle of head‐down tilt on dynamic cerebral autoregulation during combined exposure to cephalad fluid shift and mild hypercapnia

Experimental Physiology, EarlyView.
Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Static autoregulation in humans [PDF]

Journal of Cerebral Blood Flow & Metabolism
A recent publication in JCBFM, “Static autoregulation in humans” gives rise to critical comments. Autoregulation of cerebral blood flow implies that flow is rather constant within a certain blood pressure (BP) range with a lower and an upper pressure limit.

Vascular health and exercise in females throughout the lifespan: Exploring puberty, pregnancy and menopause

Experimental Physiology, EarlyView.
Abstract This narrative review highlights the impact of exercise on vascular health in females over the lifespan with an emphasis on puberty, pregnancy and menopause. These events encompass substantial changes in sex hormone levels, particularly oestrogens and progesterone.
