Lipid Structures

Lipids are an important class of molecules, being found in membranes, HDL, LDL, and other natural structures, serving essential roles in structure and with varied functions such as compartmentalization and transport. Synthetic liposomes are also widely used as delivery and release vehicles for drugs, cosmetics, and other chemicals; soap is made from lipids. Lipids may form bilayer or multilammellar vesicles, micelles, sheets, tubes, and other structures. Lipid molecules may be linked to proteins, carbohydrates, or other moieties. EM study of this essential ingredient of life has lagged, due to lack of direct methods to visualize lipids without extensive alteration. OsO4 reacts with double bonds in membrane phospholipids, forming crossbridges. This has been the method of choice to both fix and stain membranes, thus far. An earlier work described the use of tungstate clusters (W11) attached to lipid moieties to form lipid structures and lipid probes.

The Face

Children with Rett Syndrome (RS) are reported to use multiple modalities to communicate although their intentionality is often questioned (Bartolotta, Zipp, Simpkins, & Glazewski, 2011; Hetzroni & Rubin, 2006; Sigafoos et al., 2000; Sigafoos, Woodyatt, Tuckeer, Roberts-Pennell, & Pittendreigh, 2000). This paper will present results of a study analyzing the unconventional vocalizations of a child with RS. The primary research question addresses the ability of familiar and unfamiliar listeners to interpret unconventional vocalizations as “yes” or “no” responses. This paper will also address the acoustic analysis and perceptual judgments of these vocalizations. Pre-recorded isolated vocalizations of “yes” and “no” were presented to 5 listeners (mother, father, 1 unfamiliar, and 2 familiar clinicians) and the listeners were asked to rate the vocalizations as either “yes” or “no.” The ratings were compared to the original identification made by the child's mother during the face-to-face interaction from which the samples were drawn. Findings of this study suggest, in this case, the child's vocalizations were intentional and could be interpreted by familiar and unfamiliar listeners as either “yes” or “no” without contextual or visual cues. The results suggest that communication partners should be trained to attend to eye-gaze and vocalizations to ensure the child's intended choice is accurately understood.

Imagery Rehearsal

Theoretischer Hintergrund: Chronische Alpträume stellen eine weit verbreitete Schlafstörung dar, welche einen hohen Leidensdruck hervorruft. Als besonders wirksam in der Behandlung gilt die Imagery Rehearsal Therapy (IRT). Selbsthilfeprogramme stellen hierbei eine effektive, ökonomische Behandlungsoption dar. Fragestellung: Die vorliegende Pilotstudie untersucht die Wirksamkeit einer neuen, IRT-basierten, angeleiteten Selbsthilfe. Methode: 10 Patienten mit chronischen Alpträumen wurden im Rahmen von 4 face-to-face-Sitzungen vor Intervention (T1) sowie 4 Wochen (T2) und 3 Monate (T3) danach hinsichtlich Alptraumhäufigkeit sowie verschiedener psychosozialer Parameter untersucht. Ergebnisse: Die Alptraumhäufigkeit reduzierte sich innerhalb von 4 Wochen signifikant (T1-T2; Effektstärke: 1,0). Dieser Effekt blieb über 3 Monate stabil (T1-T3; Effektstärke: 1,26). Zudem reduzierten sich signifikant Depressions-, Angst- und Anspannungsparameter sowie das Stresserleben. Schlussfolgerung: Das deutschsprachige Selbsthilfemanual könnte eine wirksame Behandlungsmöglichkeit zur Reduktion von Alpträumen darstellen.

Long Term Follow Up

There are few long-term follow-up studies of parasuicides incorporating face-to-face interviews. To date no study has evaluated the prevalence of psychiatric morbidity at long-term follow-up of parasuicides using diagnostic rating scales, nor has any study examined parental bonding issues in this population. We attempted a prospective follow-up of 85 parasuicide cases an average of 8½ years later. Psychiatric morbidity, social functioning, and recollections of the parenting style of their parents were assessed using the Clinical Interview Schedule, the Social Maladjustment Scale, and the Parental Bonding Instrument, respectively. Thirty-nine persons in total were interviewed, 19 of whom were well and 20 of whom had psychiatric morbidity. Five had died during the follow-up period, 3 by suicide. Migration, refusals, and untraceability were common. Parasuicide was associated with parental overprotection during childhood. Long-term outcome is poor, especially among those who engaged in repeated parasuicides.

Abstract. A meta-analysis was performed to determine whether response rates to online psychology surveys have decreased over time and the effect of specific design characteristics (contact mode, burden of participation, and incentives) on response rates. The meta-analysis is restricted to samples of adults with depression or general anxiety disorder. Time and study design effects are tested using mixed-effects meta-regressions as implemented in the metafor package in R. The mean response rate of the 20 studies fulfilling our meta-analytic inclusion criteria is approximately 43%. Response rates are lower in more recently conducted surveys and in surveys employing longer questionnaires. Furthermore, we found that personal invitations, for example, via telephone or face-to-face contacts, yielded higher response rates compared to e-mail invitations. As predicted by sensitivity reinforcement theory, no effect of incentives on survey participation in this specific group (scoring high on neuroticism) could be observed.

Although ego-centered network data provide information that is limited in various ways as compared with full network data, an ego-centered design can be used without the need for a priori and researcher-defined network borders. Moreover, ego-centered network data can be obtained with traditional survey methods. However, due to the dynamic structure of the questionnaires involved, a great effort is required on the part of either respondents (with self-administration) or interviewers (with face-to-face interviews). As an alternative, we will show the advantages of using CASI (computer-assisted self-administered interview) methods for the collection of ego-centered network data as applied in a study on the role of social networks in substance use among college students.
