The physiological mechanisms that might be involved in an association between heat stress and sudden infant death syndrome (SIDS) are obscure. We tested the hypothesis that a combination of acute hypoxia and elevated body temperature (T(B)) might prevent autoresuscitation from hypoxic apnea (AR). We exposed 21-day-old mice (total = 216) to hyperthermia (40.5-43.5 degrees C), hypoxia, or a combi...

Guilt and shame proneness are commonly thought to be associated with culture, yet research on this relationship is fragmented often inconsistent. In a review of the existing social scientific literature, we demonstrate that no consistent between guilt shame, one hand, individualism collectivism, other, has been established. To move area forward, apply new 2-dimensional, quaternary perspective b...

In neonatal rodents, a loss of brain stem serotonin [5-hydroxytryptamine (5-HT)] in utero or at birth compromises anoxia-induced gasping and the recovery of heart rate (HR) and breathing with reoxygenation (i.e., autoresuscitation). How mean arterial pressure (MAP) is influenced after an acute loss of brain stem 5-HT content is unknown. We hypothesized that a loss of 5-HT for ∼1 day would compr...

Microvascular research is seriously hampered by the great temporal and spatial variability of the measured skin blood flow and variation in sympathetic vasomotor reflexes within and between persons. Therefore skin vasomotor reflexes were studied before and after ulnar nerve blockade within the same person, resulting in a temporal complete denervation of the fifth finger and partial denervation ...

As of 00Z 1 June 1994, the WAM wave model will become operational in the NMC, replacing the existing southern hemisphere and Australian region systems. Replacement systems will be a global version at 3 o resolution and a regional model at 1 o resolution. The new model is run on the Cray-YMP supercomputer and forcing is obtained from surface wind fields calculated from the global (GASP) and regi...

One of the predictions of game theory is that cooperative behaviours are vulnerable to exploitation by selfish individuals, but this result seemingly contradicts the survival of cooperation observed in nature. In this review, we will introduce game theoretical concepts that lead to this conclusion and show how the spatial competition dynamics between microorganisms can be used to model the surv...
