The Active Human Gut Microbiota Differs from the Total Microbiota
2011
The human gut microbiota is considered one of the most fascinating reservoirs of microbial diversity hosting between 400 to 1000 bacterial species distributed among nine phyla with Firmicutes, Bacteroidetes and Actinobacteria representing around of the diversity. One of the most intriguing issues relates to understanding which microbial groups are active players in the maintenance of the microbiota homeostasis. Here, we describe the diversity of active microbial fractions compared with the whole community from raw human fecal samples. We studied four healthy volunteers by 16S rDNA gene pyrosequencing. The fractions were obtained by cell sorting based on bacterial RNA concentration. Bacteria…

Anosognosia and Metacognition in Alzheimer’s Disease
2015
While metacognition and anosognosia have long been studied as distinct concepts, more recently we have endeavored to construct a theoretical framework for exploring how metacognition can contribute to our understanding of anosognosia and vice versa. Following this approach, with a particular focus on Alzheimer’s disease (AD), this chapter first gives an overview of the key experimental findings and issues on metacognition in AD patients: in particular, overconfidence and absolute awareness; the sensitivity approach; the fractionation of metacognition in AD; the neural substrates of metacognition in the Alzheimer brain; and metacognitive control in these patients. Second, the chapter discuss…
Dzimtes lomas luterāņu draudzē – „dabiskais” un „tradicionālais”
2015
Bakalaura darbs “Dzimtes lomas luterāņu draudzē – “dabiskais” un “tradicionālais”” ir pētījums par to, kā dzimtes lomas tiek definētas un argumentētas kādā Rīgas luterāņu draudzē organizētā pirmslaulību seminārā, vēršot uzmanību uz to, kā veidojas priekšstati un kā dzimtes lomas tiek pamatotas Baznīcā, draudzē, seminārā un semināra apmeklētāju ģimenēs. Caur dzimtes lomām ir iespējams veidot un pamatot noteiktu kārtību sabiedrībā. Pētījumā iepazīstot trīs savstarpēji saistītus dzimtes lomu argumentācijas līmeņus – Baznīcas, draudzes un individuālo, bija iespējams paraudzīties uz to, kā mūsdienās dzimtes lomu argumentācijā reliģiskā kontekstā patriarhālās ģimenes struktūras aizstāvēšana pastā…
Lessons Learned from the German Registry for Acute Aortic Dissection Type A (GERAADA) and Expectations for the Future
2014
The German Registry for Acute Aortic Dissection type A (GERAADA) is a prospective observational clinical multicenter registry that was launched in 2006. With more than 2,500 patients included from over 50 recruiting centers it is—to our knowledge—the most representative register for acute aortic dissection type A (AADA) currently available. We examined mortality and post-operative events as well as the influence of various pre- and intraoperative factors on these endpoints. Among patients registered, 30-day mortality is 15.9 %. 13.4 % of patients experienced postoperatively a new neurological deficit and a total of 10.5 % of patients suffered from permanent neurological impairment 30 days a…
Gender-related effect of clinical and genetic variables on the cognitive impairment in multiple sclerosis
2004
BACKGROUND: Cognitive impairment may occur at any time during the course of multiple sclerosis (MS), and it is often a major cause of disability in patients with the disease. The APOE-epsilon4 allele is the major known genetic risk factor for late onset familial and sporadic Alzheimer's Disease (AD), and it seems to be implicated in cognitive decline in normal elderly persons. OBJECTIVE: To investigate the clinical and genetic variables that can be associated with the cognitive decline in patients with MS. METHODS: Five-hundred and three patients with clinically definite MS underwent a battery of neuropsychological tests and, according to the number of failed tests, were divided into cognit…
Isolated, Subtle Neurological Abnormalities in Mild Cognitive Impairment Types.
2019
Isolated, subtle neurological abnormalities (ISNA) are commonly seen in aging and have been related to cerebral small vessel disease (SVD) and subcortical atrophy in neurologically and cognitively healthy aging subjects.To investigate the frequency of ISNA in different mild cognitive impairment (MCI) types and to evaluate for each MCI type, the cross-sectional relation between ISNA and white matter hyperintensities (WMH), lacunes, caudate atrophy, and ventricular enlargement.One thousand two hundred fifty subjects with different MCI types were included in the analysis and underwent brain magnetic resonance imaging. WMHs were assessed through two visual rating scales. Lacunes were also rated…
Top management team demography and firm operating performance: a path analysis
2020
PurposeThis paper examined the relationship between TMT demographic properties and firm performance using diversity and level variables and measuring differing constructs of firm performance representing divergent strategies.Design/methodology/approachStructural equation modelling was used to test the relationships between TMT demographic properties and firm performance measured as return on net operating assets (RNOA), and its disaggregates profit margin (PM) and asset turnover (ATO). Data were from 89 Finnish firms during the years 2008–2011, resulting in 320 observations.FindingsTMT team tenure had associations with RNOA through both PM and ATO while TMT age, age diversity, firm tenure, …
