[Posttraumatic stress disorder in patients after stroke]. / Simptomy posttravmaticheskogo stressovogo rasstroistva u patsientov s tserebral'nym insul'tom.

Objective. To assess the frequency of main symptoms of posttraumatic stress disorder (PTSD) in post stroke patients. Material and methods. Forty-eight patients took part in the study. We used the Impact of Events Scale (IES) and other scales to assess the severity of posttraumatic stress. Results and conclusion. Thirty three percent of patients experienced posttraumatic stress, 12.5% suffered from PTSD. We found an association between the severity of posttraumatic stress after stroke and the level of anxiety, sleep disturbances and decrease of quality of life. Symptoms of posttraumatic stress are often observed after stroke, this needs to be taken into account during planning of rehabilitation programs.

Optical pseudogap from iron states in filled skutterudites AFe4Sb12 (A=Yb, Ca, Ba).

Optical investigations are presented of the filled skutterudites AFe4Sb12 with divalent cations A=Yb, Ca, Ba. For each of these compounds a very similar pseudogap structure in the optical conductivity develops in the far-infrared spectral region at temperatures below 90 K. Highly accurate local-density approximation electronic band structure calculations can consistently explain the origin of the pseudogap structure generated largely by transition metal 3d states. In particular, a 4f-conduction electron hybridization or strong correlations can be ruled out as origin for the pseudogap.

Cell surface antigens detected in cell lines established from lymphomatous Papio hamadryas and Macaca arctoides monkeys.

Cell surface antigens associated with bone marrow cell cultures from leukemic monkeys of species Papio hamadryas and Macacus arctoides were visualized by means of an indirect immunofluorescence method with sera from leukemic baboons. The same immune serum gave two types of immunofluorescence, depending on the origin of the target cells. Fluorescence of the ring-reaction type was seen with Papio hamadryas bone marrow cell cultures growing in suspension and containing the baboon herpesvirus, whereas the patchy type of fluorescence was noted with monolayer bone marrow cell cultures from Macaca arctoides origin, containing type-C oncornavirus but not the herpesvirus particles. Absorption experiments showed that antibodies responsible for the patchy type of immunofluorescence could be absorbed with a disintegrated type-C baboon oncornavirus, and not with baboon lymphoblastoid cell lines containing the herpesvirus nor with human lymphoblastoid cell lines containing the Epstein-Barr virus.
