Abstract
Background Post-traumatic stress disorder (PTSD) and chronic pain are highly prevalent comorbid conditions. Veterans dually burdened by PTSD and chronic pain experience more severe outcomes compared to either disorder alone. Few studies have enrolled enough women Veterans to test gender differences in pain outcomes [catastrophizing, intensity, interference] by the severity of PTSD. Aim Examine gender differences in the association between PTSD symptoms and pain outcomes among Veterans enrolled in a chronic pain clinical trial. Methods Participants were 421 men and 386 women Veterans with chronic pain who provided complete data on PTSD symptoms and pain outcomes. We used hierarchical linear regression models to examine gender differences in pain outcomes by PTSD symptoms. Results Adjusted multivariable models indicated that PTSD symptoms were associated with higher levels of pain catastrophizing (0.57, 95% CI [0.51, 0.63]), pain intensity (0.30, 95% CI [0.24, 0.37]), and pain interference (0.46, 95% CI [0.39, 0.52]). No evidence suggesting differences in this association were found in either the crude or adjusted models (all interaction p-values<0.05). Conclusion These findings may reflect the underlying mutual maintenance of these conditions whereby the sensation of pain could trigger PTSD symptoms, particularly if the trauma and pain are associated with the same event. Clinical implications and opportunities testing relevant treatments that may benefit both chronic pain and PTSD are discussed.

Abstract
The social representation (SR) of conception was investigated using an adapted version of Bartlett's (1932) method of serial reproduction. A sample of 75 participants reproduced a text describing the conception process in 20 segregated chains of four reproductive generations. Changes in sentence structure and content were analysed. Results indicated that when the scientific representation of conception is apprehended by laypersons, two different processes take place. First, the abstract biological description of the process is progressively transformed into an anthropomorphic description centred on the sperm and ovum (personification). Second, stereotypical sex-role attributes are projected onto the sperm and ovum. Limitations of the method of serial reproduction are discussed, as well as its potential for modelling processes of cultural diffusion of knowledge.

Abstract
This paper recapitulates experience made over 40 years with a special nontumorous radiotherapy for the eye. Following a review of the development of therapy, which began with the pendular convergence x-ray machine and later changed to the linear accelerator, an overview is presented of the most important indications for the safe use of x-rays in exudative inflammatory processes in the posterior segment of the eye. We show that in many cases radiotherapy can achieve a permanent improvement for years or at least the preservation of the status quo, while also protecting the important visual cells, especially if it is administered at the earliest possible stage alone. However, it is even more effective in combination with retrobulbar injection therapy that is adjusted individually. Statistics on the results in cases of disciform macular degeneration, doubtlessly the most frequent indication for non-tumorous radiotherapy in the eye, exemplify its efficacy.

Abstract
A search was performed for presynaptic, release-modulating receptor systems on the post-ganglionic sympathetic nerves of rabbit pulmonary artery. Strips of the artery were preincubated with (-)-3H-noradrenaline and then superfused and stimulated transmurally. 1. Tetrodotoxin, guanethidine, and omission of calcium all suppressed the stimulation-evoked overflow of tritium, thus confirming selective release from noradrenergic neurones. 49% of the stimulation-evoked overflow of total consisted of 3H-noradrenaline, 22% of 3H-3,4-dihydroxyphenyglycol (DOPEG), and 9% of 3H-normetanephrine. Cocaine virtually abolished the evoked overflow of 3H-DOPEG; further addition of corticosterone also abolished that of 3H-normetanephrine. In the presence of cocaine plus corticosterone, unmetabolized 3H-noradrenaline accounted for 86% of the stimulation-evoked overflow of total tritium. The overflow evoked per pulse was 2.2 X 10(-5) of the tritium content of the tissue (1 Hz); it increased 2-fold when the frequency was raised to 8 Hz. 2. Presynaptic alpha-adrenoceptors have previously been demonstrated in this tissue (Starke et al., 1975b). High concentrations of isoprenaline reduced the stimulation-evoked overflow of tritium, presumably by alpha-adrenergic inhibiton. No presynaptic effect of up to 10(-5) M normetanephrine and metanephrine was found. 3. Dopamine slightly diminished the stimulation-evoked overflow of tritium, but only at 100 times the inhibitory threshold concentration of noradrenaline (which is 10(-8) M; Starke et al., 1975b), probably through activation of presynaptic alpha-adrenoceptors. Apomorphine failed to reduce the evoked overflow whether the superfusion medium contained cocaine and corticosterone or not. 4. Isoprenaline (10(-9) -10(-6) M) did not change the evoked overflow whether the medium contained cocaine and corticosterone or not, and whether the frequency was 1 or 2 Hz. Propranolol also had no effect. 5. Angiotensin II increased the stimulation-evoked overflow both in the absence and in the presence of cocaine and corticosterone. Equieffective concentrations of angiotensin I were 10 times higher. Saralasin had no effect, whereas 1-Sar,8-Ile-angiotensin produced a small increase. Both of the latter peptides behaved as presynaptic antagonists of angiotensin II. A presynaptically supramaximal concentration of the alpha-adrenergic agonist oxymetazoline prevented the facilitatory action of yohimbine, but not that of angiotensin II. Separation of 3H-compounds showed that angiotensin II caused a proportionate increase in stimulation-evoked overflow of 3H-noradrenaline, 3H-DOPEG, and 3H-normetanephrine; this finding rules out any inhibition of noradrenaline uptake mechanisms. 6. 10(-4) -10(-3) M acetylcholine caused hexamethonium-sensitive acceleration of basal tritium outflow. Much lower concentrations (10(-7) M and higher) reduced the overflow evoked by electrical stimulation. The evoked overflow of 3H-noradrenaline, 3H-DOPEG, and 3H-normetanephrine was proportionately decreased...
