Effect of a 3-week body mass reduction program on body composition, muscle function and motor performance in pubertal obese boys and girls
2005
The aim of this study was to investigate the effects of a multidisciplinary body mass reduction (BMR) program on body composition, muscle function and motor performance in 50 obese [mean body mass index (BMI): 35.9+/-5.8 kg/m2] boys and girls aged 12-17 yr (Tanner stage III, IV and V). The hospital-based BMR program combined an energy-restricted diet (1400-1600 kcal), nutritional education, psychological counselling and moderate physical activity (45-60 min/ session; 5 sessions/week; 60-80% of the maximal heart rate) during a 3-week period. Fat mass, fat-free mass, maximal power during jumping and stair climbing as well as maximal strength of the upper and lower limb muscles were quantified…
Effect of Six-Month Diet Intervention on Sleep among Overweight and Obese Men with Chronic Insomnia Symptoms : A Randomized Controlled Trial
2016
Growing evidence suggests that diet alteration affects sleep, but this has not yet been studied in adults with insomnia symptoms. We aimed to determine the effect of a six-month diet intervention on sleep among overweight and obese (Body mass index, BMI >= 25 kg/m(2)) men with chronic insomnia symptoms. Forty-nine men aged 30-65 years with chronic insomnia symptoms were randomized into diet (n = 28) or control (n = 21) groups. The diet group underwent a six-month individualized diet intervention with three face-to-face counseling sessions and online supervision 1-3 times per week; 300-500 kcal/day less energy intake and optimized nutrient composition were recommended. Controls were instruct…
Problems of the Constitutionalism of the Legal Norms related to the Restrictions of the Spread of Covid-19 infection
2022
Plašās diskusijas Latvijas sabiedrībā par Covid-19 infekcijas slimības ietekmē pieņemtajiem ierobežojumiem, to nozīmi un izpratni, kā arī Satversmes tiesā iesniegto pieteikumu skaits un ierosinātās lietas par iespējamo ar Covid-19 infekcijas slimības izplatības ierobežojumiem saistīto tiesību normu neatbilstību Satversmei norāda uz šī temata nozīmīgumu, kā arī uz to, ka par tiesību normās ietvertajiem ierobežojumiem nolūkā mazināt vīrusa slimības izplatību nav vienprātīgas nostājas. Pētījuma mērķis ir noskaidrot ar Covid-19 infekcijas slimības izplatības ierobežojumiem saistīto tiesību normu satversmības problēmas. Dažādu tiesību institūtu izpratne normatīvajos aktos un tiesību realitātē va…
Variation in communication and family visiting policies in intensive care within and between countries during the Covid-19 pandemic: The COVISIT inte…
2022
Background: During the COVID-19 pandemic, intensive care units (ICU) introduced restrictions to in-person family visiting to safeguard patients, healthcare personnel, and visitors. Methods: We conducted a web-based survey (March– July 2021) investigating ICU visiting practices before the pandemic, at peak COVID-19 ICU admissions, and at the time of survey response. We sought data on visiting pol icies and communication modes including use of virtual visiting (videoconferencing). Results: We obtained 667 valid responses representing ICUs in all continents. Before the pandemic, 20% (106/ 525) had unrestricted visiting hours ; 6% (30/525) did not allow in-person visiting. At peak, 84% (558/667…
Impact of crop species on bacterial community structure during anaerobic co-digestion of crops and cow manure
2008
The bacterial communities in three continuously stirred tank reactors co-digesting cow manure with grass silage, oat straw, and sugar beet tops, respectively, were investigated by 16S rRNA gene-based fingerprints and clone libraries. The analyses revealed both clearly distinct and similar phylotypes in the bacterial communities between the reactors. The major groups represented in the three reactors were Clostridia, unclassified Bacteria, and Bacteroidetes. Phylotypes affiliated with Bacilli or Deltaproteobacteria were unique to the sugar beet and straw reactor, respectively. Unclassified Bacteria dominated in sugar beet reactor while in the straw and grass reactor Clostridia was the domina…
Poola intertekstuaalsed meemid COVID pandeemia kohta
2021
The aim of the paper is to show the Polish story of the COVID-19 pandemic as seen through a humorous looking glass. Different stages of coronavirus presence in the media and social discourse have been accompanied by the appearance and development of jokes and memes, which illustrate the rapidly changing pandemic situation. The database consists of over three hundred memes, movies, and comments collected between February and May 2020, during the pandemic humour peak, and come mainly from private WhatsApp and Facebook accounts of the researchers. The humorous material is related to introduced restrictions, changing laws, parliamentary elections, news from other affected countries as well as s…
Molecular Identification of Yeasts Associated with Traditional Egyptian Dairy Products
2009
This study aimed to examine the diversity and ecology of yeasts associated with traditional Egyptian dairy products employing molecular techniques in yeast identification. A total of 120 samples of fresh and stored Domiati cheese, kariesh cheese, and "Matared" cream were collected from local markets and examined. Forty yeast isolates were cultured from these samples and identified using the restriction-fragment length polymorphism (RFLPs) of 5.8S-ITS rDNA region and sequencing of the domains D1 and D2 of the 26S rRNA gene. Yeasts were identified as Issatchenkia orientalis (13 isolates), Candida albicans (4 isolates), Clavispora lusitaniae (Candida lusitaniae) (9 isolates), Kodamaea ohmeri (…
Presentation of an Immunodominant Immediate-Early CD8+ T Cell Epitope Resists Human Cytomegalovirus Immunoevasion.
2013
Control of human cytomegalovirus (HCMV) depends on CD8+ T cell responses that are shaped by an individual's repertoire of MHC molecules. MHC class I presentation is modulated by a set of HCMV-encoded proteins. Here we show that HCMV immunoevasins differentially impair T cell recognition of epitopes from the same viral antigen, immediate-early 1 (IE-1), that are presented by different MHC class I allotypes. In the presence of immunoevasins, HLA-A- and HLA-B-restricted T cell clones were ineffective, but HLA-C*0702-restricted T cell clones recognized and killed infected cells. Resistance of HLA-C*0702 to viral immunoevasins US2 and US11 was mediated by the alpha3 domain and C-terminal region …
Study of the Evolutionary Relationships among Limonium Species (Plumbaginaceae) Using Nuclear and Cytoplasmic Molecular Markers
2000
The genus Limonium, due to the patchiness of the natural habitats of its species as well as the high frequency of hybridization and polyploidy and the possibility of reproduction by apomixis, provides an example of all the principal mechanisms of rapid speciation of plants. As an initial study of evolution in this genus, we have analyzed intra- and interspecific variability in 17 species from section Limonium, the largest in the genus, based on RFLPs of cpDNA and nuclear rDNA ITS sequences. In the cpDNA analysis, 21 restriction enzymes were used, resulting in 779 fragments, 490 of which were variable and 339 parsimony informative. L. furfuraceum exhibited two relatively divergent cpDNA hapl…
Consequences of antigen self-presentation by tumor-specific cytotoxic T cells.
2000
Abstract CDS-positive cytotoxic T cells (CTL) recognize antigenic peptides in combination with major histocompatibility complex (MHC) class I molecules on the surface of syngeneic antigen presenting cells (APC). In the present paper we show that cells from tumor antigen-specific CTL clones present their cognate antigenic peptide to other CTL from the same clone. Inter-CTL peptide presentation resulted in activation of the cells of one CTL clone to MHC-unrestricted lysis of bystander cells. In contrast to the behaviour of this clone, another CTL clone did not lyse bystander cells after incubation with the cognate peptide, but was activated to self-destruction. The human herpes virus Epstein-…
