Online compulsive buying-shopping disorder and social networks-use disorder: More similarities than differences?

Background: Studies in convenience, non-clinical samples of young adults suggest overlap between online compulsive buying-shopping disorder (OCBSD) and social-networks-use disorder (SNUD). Considering the dearth of research, this study investigated OCBSD and SNUD in clinical samples.

Methods: Women with either OCBSD (n = 37) or SNUD (n = 41) were compared regarding sociodemographic variables, use time of the first-choice application, OCBSD/SNUD severity, general internet use, impulsivity, materialism, perceived chronic stress and the frequency of viewing posts of influencers and the urge to visit shopping websites or social networks after viewing influencer posts.

"Is it us or is it me?": Family experiences of connectedness following a reflecting team intervention.

The present study examined family-wide versus individual perceptions of, and changes in, family connectedness in response to a one-time reflecting team (RT) intervention. Seventy-six families (N = 208 individuals), recruited during family therapy, completed family connectedness measures before and after the RT intervention. A subset of adults (n = 26) completed 1-week follow-up measures.

Looking into the One-way Mirror: A Pilot Study on the Impact of Reflecting Teams on Family Members.

Reflecting Teams (RTs) are an internationally recognized clinical consultation methodology, first developed by Tom Andersen in 1985. Over the last three decades, family therapists around the world have used RTs to enhance treatment. However, this innovation to family therapy practice is not well-standardized nor evaluated.

Dopamine physiology in the basal ganglia of male zebra finches during social stimulation.

Accumulating evidence suggests that dopamine (DA) is involved in altering neural activity and gene expression in a zebra finch cortical-basal ganglia circuit specialized for singing, upon the shift between solitary singing and singing as a part of courtship. Our objective here was to sample changes in the extracellular concentrations of DA in Area X of adult and juvenile birds, to test the hypothesis that DA levels would change similarly during presentation of a socially salient stimulus in both age groups. We used microdialysis to sample the extracellular milieu of Area X in awake, behaving adult and juvenile male zebra finches, and analysed the dialysate using high-performance liquid chromatography coupled with electrochemical detection.

Positive psychological outcomes of spaceflight: an empirical study.

Introduction: Anecdotes from astronauts and cosmonauts suggest that spaceflight can be an enriching experience with enduring positive effects. These positive mental health effects may help protect flight crews from the psychological stress inherent in such high-risk missions. The goal of this study was to identify areas of personal growth likely to result from traveling in space and explore how they were patterned.

Positive psychological effects of space missions.

Being in space is a powerful experience that can have an enduring, positive impact on the psychological well-being of astronauts and cosmonauts. We sought to examine the frequency, intensity and distribution of such salutogenic experiences among persons who have flown in space, using a questionnaire we developed based on the scientific literature and first person accounts. All participants reported positive effects of being in space, but the degree of change varied widely, and some experiences were particularly common.

Modulation of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor desensitization by extracellular protons.

The interstitial milieu of the brain is buffered to an average pH of 7.3, but synaptic activation produces a temporal sequence of events that can affect pH in the synaptic cleft. Furthermore, pathophysiological processes such as ischemia and seizures produce global and prolonged acidification of interstitial pH.

AMPA receptor current density, not desensitization, predicts selective motoneuron vulnerability.

Spinal motoneurons are more susceptible to AMPA receptor-mediated injury than are other spinal neurons, a property that has been implicated in their selective degeneration in amyotrophic lateral sclerosis (ALS). The aim of this study was to determine whether this difference in vulnerability between motoneurons and other spinal neurons can be attributed to a difference in AMPA receptor desensitization and/or to a difference in density of functional AMPA receptors. Spinal motoneurons and dorsal horn neurons were isolated from embryonic rats and cultured on spinal astrocytes.

Electron microscopical investigation of citrate lyase single molecules.

Electron micrographs of citrate lyase from Rhodopseudomonas gelatinosa and Klebsiella aerogenes reveal two characteristic molecular forms. The "basket" form and the "star" form were subjected to two-dimensional image reconstruction using a technique involving averaging of superposed single molecular images after rotational correlation. A three-dimensional image reconstruction shows that the images of these forms can be interconverted by rotation and that they therefore represent different views of the same structure.

[Status of fibrinolysis in systemic lupus erythematosus].

In patients with systemic lupus erythematosus (SLE) both a haemorrhagic diathesis and a tendency to thrombosis of the venous and arterial vessels can be observed. In the course of the disease, thrombosis of the leg or pelvic veins developed in 20 per cent of 188 patients. The levels of alpha 2-plasmin inhibitor, plasminogen, fibronectin and of factor VIII complex were increased in patients with SLE compared with a control group.

[Thrombocyte counting with the Laborscale (PSL-1/PSA-1) particle-counting instrument by Medicor (Budapest/Hungary) and thrombocyte volume analysis in the diagnosis of selected thrombocytopathies].

A thrombocyte counting technique is presented in comparison with the chambre counting according to the German Book of Medicaments (DAB 7 D.L.) GDR on the particle counting device "Laborscale" (PSL-1/PSA-1) of Medicor by using a thrombofuge (70 g).

Protein and glycoprotein abnormalities in an unusual subtype of Glanzmann's thrombasthenia.

A patient with Glanzmann's thrombasthenia has been analysed by high resolution two-dimensional polyacrylamide gel electrophoresis and crossed immunoelectrophoresis. Although clot retraction is subnormal, glycoproteins IIb and IIIa are completely absent and platelet fibrinogen is strongly reduced indicating an unusual subtype of type II thrombasthenia. No changes in the pI of glycoproteins have been observed.

[The ultrastructure of megathrombocytes in May-Hegglin's anomaly].

A clinical and extensive electron microscopic study was made of the circulating granulocytes and thrombocytes from three female patients of a family with May-Hegglin anomaly. There have been observed inclusion bodies (Döhle-bodies) in a high proportion of polymorphonuclear leukocytes as well as a thrombocytopenia and giant platelets (so-called megathrombocytes). Other family members did not show hematologic abnormalities.

[Gout in the age (author's transl)].

The importance of the gout is growing in the GDR as its frequency has been increasing since the sixties. The gout is a disease of metabolism with the following accompanying phenomena: renal lesion in gout, hypertension, cardiac diseases and peripheral arterial diseases. Besides, there are proved relations between hyperuricemia and obesity, hyperlipoproteinemia, diabetes mellitus as well as steatosis hepatis.
