BAG3 and friends: co-chaperones in selective autophagy during aging and disease.
2011
There is a reciprocal change in the expression of two members of the BAG (Bcl-2-associated athanogen) family, BAG1 and BAG3, during cellular aging and under acute stress ("BAG1-BAG3-switch"). BAG3 was recently described as a mediator of a novel macroautophagy pathway that uses the specificity of heat shock protein 70 (HSP70) to misfolded proteins and also involves other protein partners, such as HSPB8. Also crucial for induction and execution of autophagy are sequestosome-1/p62 (SQSTM1/p62) and LC3, an autophagosome-associated protein. In this novel pathway, BAG3 mediates the targeting and transport of degradation-prone substrates into aggresomes via the microtubule-motor dynein. Interestin…
Associations Between Lipoprotein Subfractions and Area and Density of Abdominal Muscle and Intermuscular Adipose Tissue: The Multi-Ethnic Study of At…
2021
Skeletal muscle quantity and quality decrease with older age, which is partly attributed to ectopic fat infiltration and has negative metabolic consequences. To inform efforts to preserve skeletal muscle with aging, a better understanding of biologic correlates of quantity and quality of muscle and intermuscular adipose tissue (IMAT) is needed. We used targeted lipidomics of lipoprotein subfractions among 947 Multi-Ethnic Study of Atherosclerosis participants to provide a detailed metabolic characterization of area and density of abdominal muscle and IMAT. Serum lipoprotein subfractions were measured at the first visit using 1H-Nuclear Magnetic Resonance spectroscopy. Muscle and IMAT area (…
"Piosenka jest dobra na wszystko" : propozycja bloku zajęć zapoznających studentów obcojęzycznych z wybranymi utworami twórców polskiej piosenki
2022
Artykuł stanowi omówienie propozycji bloku zajęć adresowanych do studentów obcojęzycznych, którego celem jest wzmocnienie kompetencji językowych, ale także przybliżenie sylwetek kilku znaczących reprezentantów polskiej sceny muzycznej: Czesława Niemena, Agnieszki Osieckiej, Wojciecha Młynarskiego, Kabaretu Starszych Panów. W założeniu ma to służyć podniesieniu motywacji cudzoziemców do nauki języka polskiego. Zaproponowane zajęcia są adresowane do studentów posługujących się językiem polskim co najmniej na poziomie B1+/B2, jednak - biorąc pod uwagę - holistyczne podejście do nauczania języka obcego, można na ich podstawie skonstruować serię zadań doskonalących różnorakie kompetencje językow…
Similar endometrial development in oocyte donors treated with either high- or standard-dose GnRH antagonist compared to treatment with a GnRH agonist…
2005
Background This descriptive study evaluates the impact on endometrial development of standard and high doses of a GnRH antagonist in stimulated cycles compared with GnRH agonist and natural cycles. Methods Thirty-one oocyte donors were treated with a combination of rFSH and 0.25 mg/day ganirelix (standard dose), 2 mg/day ganirelix (high dose) or 0.6 mg/day buserelin (long protocol). Vaginal progesterone (200 mg/day) was administered in the luteal phase. Endometrial biopsies were performed 2 and 7 days after HCG administration. Additional biopsies were carried out in a subset of 12 subjects, 2 and 7 days following the LH peak of their previous natural cycle. Biopsies were evaluated histologi…
Homodimeric murine interleukin-3 agonists indicate that ligand dimerization is important for high-affinity receptor complex formation.
1994
Homodimeric murine interleukin 3 (mIL-3) agonists were generated by intermolecular cystine-bonding. Steady-state binding assays and association kinetics performed at 4 degrees C using these agonists revealed specific binding to both the high- and low-affinity receptor. DSS-mediated crosslinking studies performed at 4 degrees C with agonist concentrations compatible with high-affinity receptor complex formation allowed to detect protein complexes of the alpha chain, the beta chain(s) and the high-affinity receptor complex migrating with apparent molecular weights of 90 kDa, 140 kDa, and above 180 kDa, respectively. In contrast, monomeric mIL-3 was crosslinked to the alpha chain receptor only…
A Meta-Analysis of the Effects of Teacher Personality on Teacher Effectiveness and Burnout
2019
The question of what makes a good teacher has been asked by practitioners, policymakers, and researchers for decades. However, there is no guiding framework about which qualities are important for teachers. Thus, it is necessary to examine these qualities using a recognized framework and to summarize the previous literature on this topic. We conducted a meta-analysis on the 25 studies (total N = 6294) reporting the relationships between teacher Big Five personality domains (openness, conscientiousness, extraversion, agreeableness, and emotional stability) and two teacher job-related outcomes (i.e., teacher effectiveness and burnout). Furthermore, the influence of three moderators was assess…
Associations between personality, sports participation and athletic success. A comparison of Big Five in sporting and non-sporting adults
2018
Abstract The present study investigates whether the Big Five personality traits are different among diverse sports populations. A sample of 881 male athletes and non-athletes completed a self-report questionnaire measuring their personality traits. The Exploratory Structure Equation Modeling (ESEM) approach is adopted to test measurement invariance and mean differences among groups. The results indicate that athletes who had experienced the most success in their sport scored higher than non-athletes in each personality dimension of the Big Five, with the exception of openness, while less successful athletes scored higher than non-athletes only in extraversion and agreeableness. The more suc…
First insights into weed communities of rice agrocoenoses in southern Thailand
2015
The study presents the results of geobotanical investigations conducted in rice fields in southern Thailand in 2013. It is focussed on the classification of plant communities poorly investigated from a geobotanical standpoint. Altogether 125 phytosociological relevés were collected, using the Braun-Blanquet method. We noted more than 100 species in the vegetation plots, including many rare ones. We classified the vegetation into seven communities, including six associations. Five associations are proposed as new: Nymphaeetum nouchali, Fimbristylido miliaceae-Sphenocleetum zeylanicae, Ischaemo rugosi-Cyperetum pulcherrimi, Pentapeto phoeniceae-Aeschynomenetum indicae and Marsileetum minutae.…
Weed communities of rice fields in the central Pamir Alai Mountains (Tajikistan, Middle Asia)
2013
The study present results of geobotanical investigations conducted in rice fields in the central Pamir Alai Mts (Tajikistan, Middle Asia), mainly within Syr-Daria, Pyandzh, Zeravshan, Kafirnigan, Khanaka and Surkhandaria river valleys in the years 2009–2011. The researches were focused on classification of plant communities developing within this poorly investigated area. Habitat conditions were checked including conductometry, pH reaction, temperature, depth of water and, for several plots, also soil structure. Altogether 114 phytosociological relevés using the Braun-Blanquet method were sampled. The analyses classified the vegetation into 28 communities including 24 associations. Five new…
Soil organic carbon stocks under recommended management practices in different soils of semiarid vineyards
2019
The Intergovernmental Panel on Climate Change (IPCC) approach is widely used to estimate the C account through the use of standardized coefficients that are not site specific. For these reasons, the aim of the work was to define specific IPCC coefficient taking into account differences in pedological characteristics that affect soil C steady state. In a vineyard area of Sicily, the effectiveness of 5 years of recommended management practice (RMP) adoption on soil organic carbon (SOC) stock increases was evaluated by considering 100 paired sites distributed over four functional soil groups. Each site consisted of two neighbouring plots. The soil of one plot was managed with cover crops accor…
