Electric footshock elicited an immediate burst of activity followed by a period of immobility termed freezing. Naloxone, an opiate antagonist, enhanced both of these postshock reactions (Experiment 1). Naloxone's effects on the active and inactive components of the postshock reaction paralleled those of increasing shock intensity (Experiment 2). This finding suggests that the drug caused these ...

Ground reaction force (GRF) parameters have been used to predict tibial shock in rearfoot strike patterns (Hennig & Lafortune, 1991). However, forefoot strike (FFS) runners have significantly different GRF parameters when compared to rearfoot strike (RFS) runners (Williams, D.S., et al., in press). A typical FFS running pattern results in significantly lower vertical GRF loading rates (ZLR) and...

Sambalpur is a district in which shepherds, cultivators and shikaris are not infrequently mauled by tigers, panthers, and bears. These people when thus attacked invariably come to hospital for treatment as they are always aware of the seriousness of their wounds. The principal symptoms associated with these wounds are shock, great pain, torpor, and thirst. The main physical sig"s are inflammati...

In this paper the zero reaction limit of the hyperbolic conservation law with stiff source term of monostable type ∂tu+ ∂xf(u) = 1 u(1− u) is studied. Solutions of Cauchy problems of the above equation with initial value 0 ≤ u0(x) ≤ 1 are proved to converge, as → 0, to piecewise constant functions. The constants are separated by either shocks determined by the Rankine-Hugoniot jump condition, o...

This paper provides new evidence on the channels of monetary policy transmission combining 9 million observations firm level investment and high-frequency identified shocks. We show that reaction firms’ to a shock is heterogeneous along dimensions correspond two main transmission. First, we young firms are more sensitive shocks high leverage amplifies effects, supporting existence credit channe...

The study investigates the oblique detonation characteristics in a stoichiometric methane–air mixture employing reactive Euler equations coupled with detailed chemical reaction model. analysis evaluates initiation variation for both inflow Mach number and wedge angle. results show that an increase from M0 = 9 to 12 changes shock-to-detonation transition abrupt smooth type. Furthermore, distinct...

The heat shock response is a universal homeostatic cell autonomous reaction of organisms to cope with adverse environmental conditions. In mammalian cells, this response is mediated by the heat shock transcription factor Hsf1, which is monomeric in unstressed cells and upon activation trimerizes, and binds to promoters of heat shock genes. To understand the basic principle of Hsf1 activation we...

Adaptation to altitude hypoxia under conditions of conflict between thirst and defensive motivation was studied. The subjects adapted to altitude hypoxia made three times more attempts to drink from a water bowl despite receiving an intense shock. Adaptation to altitude hypoxia increased the stability of an initiated drinking reaction over intense shock. In adapted animals that began to drink, ...

An overlapping generations model with two production factors and two types of agents is considered in presence of ...nancial intermediation. The research focuses at the analysis of the consequences of a suddain negative production shock on a ...nancial intermediation capacities and consequently on the economy as a whole.

We report the proper management of a severe adverse reaction of anaphylactic shock during intravenous fluorescein angiography at an outpatient clinic. A 72-year-old male developed the severe, life-threatening complication after intravenous injection of sodium fluorescein dye for retinal angiography. Three minutes after receiving an intravenous injection of fluorescein, the patient developed syn...
