Abstract The paper presents a technique for micropropagation of endangered in Europe and extinct Poland Pulsatilla vulgaris ex situ conservation the genetic resources. Genotype-dependent induction somatic embryogenesis rooting was revealed series two experiments (I II) performed under same experimental conditions. Shoot tips seedlings were best explants both Murashige Skoog (MS) medium suppleme...

Pulmonary ventilation and pulmonary arterial pressure both rise progressively during the first few hours of human acclimatization to hypoxia. These responses are highly variable between individuals, but the origin of this variability is unknown. Here, we sought to determine whether the variabilities between different measures of response to sustained hypoxia were related, which would suggest a ...

This paper describes a protocol for the efficient vegetative propagation of Cleome rosea by somatic embryogenesis. Leaf and stem explants from nursery-grown seedlings of C. rosea were cultivated on Murashige and Skoog (MS) medium supplemented with indole-3-acetic acid (IAA), α-naphthaleneacetic acid (NAA), 4-amino-3,5,6trichloropicolinic acid (picloram) or 2,4-dichlorophenoxyacetic acid (2,4-D)...

OBJECTIVE If the body fails to acclimatize at high altitude, acute mountain sickness (AMS) may result. For the early detection of AMS, changes in cardiac autonomic function measured by heart rate variability (HRV) may be more sensitive than clinical symptoms alone. The purpose of this study was to ascertain if the changes in HRV during ascent are related to AMS. METHODS We followed Lake Louis...

Chronic hypoxia increases the sensitivity of the central nervous system to afferent input from carotid body chemoreceptors. We hypothesized that this process involves N-methyl-D-aspartate (NMDA) receptor-mediated mechanisms and predicted that chronic hypoxia would change the effect of the NMDA receptor blocker dizocilpine (MK-801) on the poikilocapnic hypoxic ventilatory response (HVR). Male Sp...

BACKGROUND Investigators have examined whether heat mortality risk is increased in neighborhoods subject to the urban heat island (UHI) effect but have not identified degrees of difference in susceptibility to heat and cold between cool and hot areas, which we call acclimatization to the UHI. OBJECTIVES We developed methods to examine and quantify the degree of acclimatization to heat- and co...
