OBJECTIVE Empirically based studies have demonstrated that prolonged exposure therapy effectively reduces posttraumatic stress disorder (PTSD) symptoms in a vast range of traumas, yet reports of the efficacy of such therapies in combat- and terror-related PTSD are scarce. In this article, we examine the efficacy of prolonged exposure therapy in combat- and terror-related PTSD in comparison to t...

The Serpent Mound structure is a deeply eroded ancient impact in south central Ohio, about 8.0 km across. The age of the structure is poorly constrained by the geology. It post-dates the Lower Mississippian (ca.330 Ma) Cuyahoga Formation and predates Illinoisian glacial deposits. We analyzed the directions of magnetization of 60 rock samples taken from borehole cores drilled within and in the v...

In a prospective study of 1000 consecutive primigravidae labour was induced on 95 occasions. None of 16 perinatal deaths and none of 4 cases of suspected brain damage occurred after prolonged pregnancy or pre-eclampsia. It is concluded that a low incidence of induction is compatible with good results and that enthusiasm for the statistical concept of high risk in obstetric practice should be re...

BACKGROUND Expected date of delivery (EDD) is estimated from the last menstrual period (LMP) or ultrasound scan. Conflicts between these estimates especially on the part of the physician and his/her patient could pose a challenge to prevention of prolonged pregnancy. The objective of this study was to determine the perception and acceptability of menstrual dating (EDD derived from LMP) with reg...

The adaptation of Porphyromonas gingivalis to H2O2-induced stress while inducible is modulated by an unknown OxyR-independent mechanism. Previously, we reported that the PG_2212 gene was highly upregulated in P. gingivalis under conditions of prolonged oxidative stress. Because this gene may have regulatory properties, its function in response to H2O2 was further characterized. PG2212, annotate...

T lymphocytes undergo apoptosis in response to cellular stress, including UV exposure and gamma irradiation. However, the mechanism by which stress stimuli induce apoptosis is not well understood. While stress stimuli induce the activation of the c-Jun N-terminal kinase (JNK) pathway, it is not clear whether the JNK cascade is activated as a result of cell death or whether the cascade participa...

Supplemental O(2) is commonly employed in patients with respiratory failure; however, hyperoxia is also a potential contributor to lung injury. In animal models, hyperoxia causes oxidative stress in the lungs, resulting in increased inflammation, edema, and permeability. We hypothesized that oxidative stress from prolonged hyperoxia leads to endoplasmic reticulum (ER) stress, resulting in activ...

The production of H2O2 is critical for brassinosteroid (BR)- and abscisic acid (ABA)-induced stress tolerance in plants. In this study, the relationship between BR and ABA in the induction of H2O2 production and their roles in response to heat and paraquat (PQ) oxidative stresses were studied in tomato. Both BR and ABA induced increases in RBOH1 gene expression, NADPH oxidase activity, apoplast...

BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) has been employed for decades as a non-pharmacologic treatment for post-traumatic stress disorder (PTSD). Although a link has been suggested between PTSD and impaired sensorimotor gating (SG), studies assessing the effects of rTMS against PTSD or PTSD with impaired SG are scarce. AIM To assess the benefit of rTMS in a rat model of...

As a consequence of global change processes, plants will be increasingly challenged by extreme climatic events, against a background of elevated atmospheric CO2. We analysed responses of Arabidopsis thaliana to a combination of heat wave and water deficit at ambient and elevated CO2, and provided mechanistic insight on changes in primary metabolism. Climate extreme-induced metabolic changes are...
