Video game addiction in the form of “Internet gaming disorder” (IGD) was included in Section 3 of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association [APA], 2013 ). In addition, the
A tanulmány áttekinti a szomatizáció jelenségkörét övező fogalmi bizonytalanságot és felvázolja megszületésének episztemológiai és ontológiai előfeltételeit. A hisztéria történetének rövid felidézése után ismerteti a közelmúltban mostohán kezelt konverzió fenomenológiáját, modern elméleteit és a lehetséges patomechanizmusra utaló kutatásokat. Végül beszámol a szóban forgó klinikai jelenségek új felosztási javaslatáról, a DSM-V előkészítésével megbízott kutatócsoport előzetes közleménye alapján.
A 6 × 6 diallel cross among three sensitive (18180-II, 18205-I, 18205-I and DN-18) and three tolerant (18194-II, DN-4, and LU-26S) wheat genotypes was analyzed. Thirty-six genotypes were sown in a triplicates completely randomized design in hydroponics culture. Data for root length was recorded in three salinity levels, i.e. control, 10 and 15 dSm−1. Combining ability effects controller tolerance in the two salinity levels (10 and 15 dSm−1). The genotypes 18194-II and LU-26S exhibited highest general combining abilities under10 and 15 dSm−1. The cross combinations with highest specific combining ability for root length were 18194-II × DN-4, 18180-II × 18205-I and LU26S × DN-18 under salinity levels. In reciprocals the crosses DN-18 × DN-4 and DN-4 × 18205-I appeared to be superior to the others under high salinity levels. DN-4 × LU26S produced significantly longer roots than its better parent and thus showed highest heterobeltiosis in high salinity level.

Az összefoglaló közleményben a szerzők részletesen bemutatják a Parkinson-kórhoz
társuló neurokognitív zavarok jellegzetességeit, felmérésük lehetséges módjait
és kezelési lehetőségeit. A neurokognitív zavarok meghatározását sokáig
nehezítette a diagnosztikai kritériumrendszerek sokszínűsége. Az Amerikai
Pszichiátriai Társaság által a Mentális Rendellenességek Kórmeghatározó és
Statisztikai Kézikönyvének ötödik átdolgozása (Diagnostic and Statistical Manual
of Mental Disorders, DSM-5) magával hozta a major és az enyhe neurokognitív
zavar megnevezéseket a demencia és az enyhe kognitív zavar fogalmát
helyettesítendően. A DSM-5 neurokognitív zavarra vonatkozó definíciói a
klinikumban jól alkalmazhatóak, ám szükségessé vált a leggyakrabban használt
szűrőtesztek, úgymint a Mini-Mentál Státus Vizsgálat, az Addenbrooke Kognitív
Vizsgálat, a Montreal Kognitív Felmérés és a Mattis Demencia Pontozó Skála új
kritériumrendszerhez való adaptálása. Magyar Parkinson-kóros populáción végzett
validálási vizsgálatok alapján a minor neurokognitív zavarra vonatkozóan a
legjobb diszkriminációs képességgel rendelkező határértékek az iskolázottság
mértékétől függően változnak (Addenbrooke Kognitív Vizsgálat: 0–8 év
iskolázottság esetén: 82,5, 9–12 év esetén: 83,5, ≥13 év esetén: 84,5 pont;
Mini-Mentál Státus Vizsgálat: 26,5–27,5–28,5 pont; Montreal Kognitív Felmérés:
23,5–24,5–24,5 pont; Mattis Demencia Pontozó Skála: 138,5–139,5–139,5 pont).

The primary purpose of these researches was to optimize single-cell protein (SCP) production process using Saccharomyces cerevisiae NCAIM Y.00200 and Kluyveromyces marxianus DSM 4908 strain, and then to analyse the changes in yield of single-cell protein final product using vitamin supplementation. To determine these values, the total sugar content of the fermentation medium, and the protein content of the yeast was determined. During our work, a particular attention was paid to the change of sugar content and yeast protein quantity. Besides, yield (Yx/s) values, typical of the whole fermentation, were also measured. Protein yield, as the final product of fermentation, featured the efficiency of our work. The results of our optimized trial settings that were considered as control, using S. cerevisiae NCAIM Y.00200 and K. marxianus DSM 4908 strains, were compared with the results of vitamin-supplemented fermentation processes. On this basis, we can say that during our trials vitamin supplementation did not influence the final product yield of processes. The counted protein yields during fermentation were between 0.4–0.7 g g−1.

Six strains (Bi11, Bi30, Bi36, Bi50, Bi52 and Bi55) isolated from bio-yoghurts and two strains (KD10 and KD11) derived from human faeces were identified by genus- and species specific polymerase chain reaction (PCR) with reference to the type strains of
DSM 10140 and
DSM 20104. The isolates were differentiated by using
I endonucleases for subsequent pulsed field gel electrophoresis (PFGE) technique and by API 50 CHL tests.All the isolates tested were classified to
subsp. lactis species. The reliable identification as
(by PCR with Bflact2/Bflact5 primers), however, required confirmation by a negative result of
-specific PCR.Differentiation of the
isolates with PFGE method enabled to distinguish KD11 strain with all the restriction enzymes applied, and Bi11 and Bi30 — exclusively with
I enzymes, respectively. The biochemical tests, however, revealed that all the strains tested were characterised by a unique fermentation pattern. It was concluded that differentiation of the
strains should be carried out on the basis of both genetic and phenotypic features.

The parents (the landrace Chinese spring (CS) and a synthetic hexaploids (S6x)) and 17 derived single chromosome substitution lines (SL) were grown in parallel in the field under non-saline (1.0 dSm−1) and saline (12.0 dSm−1) conditions, and evaluated for a set of phenotypic traits. The performance of CS indicated it to have borderline salinity tolerance with respect to all of the traits except for leaf area (for which it behaved in as a salinity sensitive type). The SL 4D was early in booting, ear emergence, flowering and maturity, while 5D and 2B SLs were both late. The 2B SL produce 33% more ears than CS. The 5D SL under-performed with respect to ear weight, grain number per ear, grain weight per ear and 1000-grain weight both under non-saline and saline conditions. Under saline conditions, four SLs (1A>5A>1D>2B) outperformed Cs for ear length, and six SLs (1D>6A>4B>3A>3B>3D) showed an improved grain weight. The grains produce by the 2B SL were smaller than those of CS. Leaf area developed better in four SLs (4D>2B>1A>7D) than in CS.
Universality through standardization is at the heart of scientific and medical practices. In this study we dealt with the
meaning, significance, and implications of standardization through “operationalization” in psychiatric diagnostic criteria
by focusing on the effects of the DSM (Diagnostic Statistical Manual) III. What does “operational” mean?* The discussion
of “operationalization” in psychiatric diagnosis poses quite a challenge. Given the importance of semantics and the word networks
of everyday life in forming descriptions of symptoms and reaching clinical judgments, cultural differences in these semantics
inevitably have strong impacts on psychiatric diagnosis. The link between sensitivity and semantics in words enhances this
effect. In spite of the difficulties in approaching operationalization in psychiatric diagnosis, several attempts have been
made to standardize diagnostic criteria. Prominent examples include the DSM of the American Psychiatric Association and the
ICD (International Disease Classification) of the WHO. In this paper we analyzed the effects of standardized diagnostic criteria
by performing a content analysis of papers published in the Archives of General Psychiatry from 1978 to 1990. Our results
clearly show changes in the research questions, research designs, methodologies, target diseases, and selections of independent
and dependent variables.

Aim of the study: We assessed exercise dependence (ED), alcohol and nicotine use disorders, eating disorders, hypochondria and compulsive buying and in a population of customers of a Parisian sport shop. Methods: Five hundred consecutive customers of a sport shop were invited to participate. Diagnostic of exercise dependence was made with the Exercise Addiction Inventory and a specific questionnaire checking all diagnostic criteria. The DSM-IV-TR criteria for bulimia, alcohol and nicotine use disorders were checked and all subjects answered the CAGE and Fagerström questionnaires. Hypochondria was assessed with the DSM-IV-TR criteria and the Whiteley Index of Health Anxiety. For all parameters, customers with (ED+) and without (ED-) exercise dependence were compared. Results: The prevalence of exercise dependence was 29.6%. Subjects from the ED+ group were younger than in the ED-group (27.1 vs 29.8 years) and there were more women. They were more dependent on alcohol, had higher scores at the CAGE questionnaire. ED+ subjects more often presented hypochondria (23 vs 15%), bulimia and binge eating and they more often made gifts to themselves and to others. Conclusions: Exercise dependence appears as a frequent and almost always unrecognized form of behavioral dependence in non clinical population frequenting sport shops. It is frequently associated to chemical dependence and eating disorders.
