Gesture deficits and apraxia in schizophrenia.
Walther S, Mittal VA, Stegmayer K, Bohlhalter S. Walther S, et al. Among authors: stegmayer k. Cortex. 2020 Dec;133:65-75. doi: 10.1016/j.cortex.2020.09.017. Epub 2020 Oct 3. Cortex. 2020. PMID: 33099076 Free PMC article. Review.
Notably, the review indicated that gesture deficits are severe enough to be considered genuine apraxia in a substantial proportion of patients (about 25%). Further, other potential contributors (e.g., hypokinetic motor abnormalities, cognitive impairment) are indeed associ …

Foucher JR, et al. Among authors: stegmayer k. Eur Neuropsychopharmacol. 2022 Mar;56:60-73. doi: 10.1016/j.euroneuro.2021.11.008. Epub 2021 Dec 20. Eur Neuropsychopharmacol. 2022. PMID: 34942409 Review.
Conversely, the Wernicke-Kleist-Leonhard school pursued Kahlbaum's neuropsychiatric approach and described many new psychomotor signs, e.g. parakinesias, Gegenhalten. They distinguished 8 psychomotor phenotypes of which only 7 are catatonias. ...

Over the last three decades, movement disorder as well as sensorimotor and psychomotor functioning in schizophrenia (SZ) and other psychoses has gained greater scientific and clinical relevance as an intrinsic component of the disease process of psychotic illness; this extends to …

Hypogammaglobulinemia: A contributing factor to multiple sclerosis fatigue?
Diem L, Evangelopoulos ME, Karathanassis D, Natsis V, Kamber N, Hammer H, Friedli C, Chan A, Helbling A, Penner IK, Salmen A, Walther S, Stegmayer K, Hoepner R. Diem L, et al.

Whole genome analysis of codon usage in Echinococcus.
Maldonado LL, Stegmayer G, Milone DH, Oliveira G, Rosenzvit M, Kamenetzky L. Maldonado LL, et al. Among authors: stegmayer g. Mol Biochem Parasitol. 2018 Oct;225:54-66. doi: 10.1016/j.molbiopara.2018.08.001. Epub 2018 Aug 3. Mol Biochem Parasitol. 2018. PMID: 30081061 Free article.
The gene annotations and the expression profile of 7613 genes allowed to accurately determine 27 optimal codons for the Echinococcus species, most of them ending in G/C. Approximately the 30% of Echinococcus genes analysed exhibits higher codon usage bias as well as a high …
