Meaning in Life Buffers the Association between Perceived Burdensomeness, Thwarted Belongingness, and Frequency of Non-Suicidal Self-Injuries in Span…
2021
Background: Adolescence is a developmental stage when there is a high risk of engaging in non-suicidal self-injury (NSSI). There is recent interest in the study of thwarted belongingness and perceived burdensome as variables associated with the frequency of NSSI in adolescents. Meaning in life (MIL) might be negatively associated with thwarted belongingness and perceived burdensomeness. To date, no studies have analyzed the buffering role of MIL in the association between thwarted belongingness and perceived burdensomeness and the frequency of lifetime NSSI in Spanish adolescents. Aims: (a) To test whether thwarted belongingness and perceived burdensomeness are associated with frequency of …
Lihassolurakenteen ja entsyymiaktiivisuuksien yhteydet isometriseen voimantuottoon, maksimijuoksunopeuteen sekä juoksun taloudellisuuteen
2000
Riikka Kivelä: Lihassolurakenteen ja entsyymiaktiivisuuksien yhteydet isometriseen voimantuottoon, maksimijuoksunopeuteen sekä juoksun taloudellisuuteen. Tutkimuksen tarkoituksena oli selvittää lihaksen biokemiallisten ominaisuuksien (myosiinin raskasketjukoostumus, lihassolujakauma ja entsyymiaktiivisuudet) yhteyttä maksimivoimaan ja voimantuottonopeuteen, maksimijuoksunopeuteen sekä juoksun taloudellisuuteen eri nopeuksilla. Energiantuottoon vaikuttavista entsyymeistä tarkasteltiin kahden aerobisen (CS ja HAD) sekä kahden anaerobisen (PFK ja LDH) entsyymiaktiivisuuksia. Kymmenen Suomen parhaimmistoon kuuluvan keskimatkan (800-5000 metrin) miesjuoksijan juoksun taloudellisuutta mitattiin v…
Recent experiments at the JYFLTRAP Penning trap
2020
AbstractThe JYFLTRAP double Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility offers excellent possibilities for high-precision mass measurements of radioactive ions. Around 400 atomic masses, including around 50 isomeric states, have been measured since JYFLTRAP became operational. JYFLTRAP has also been used as a high-resolution mass separator for decay spectroscopy experiments as well as an ion counter for fission yield studies. In this contribution, an overview of recent activities at the JYFLTRAP Penning trap is given, with a focus on nuclei discussed in the PLATAN2019 meeting.
Studying Gamow-Teller transitions and the assignment of isomeric and ground states at $N=50$
2022
Direct mass measurements of neutron-deficient nuclides around the N=50 shell closure below $^{100}$Sn were performed at the FRS Ion Catcher (FRS-IC) at GSI, Germany. The nuclei were produced by projectile fragmentation of $^{124}$Xe, separated in the fragment separator FRS and delivered to the FRS-IC. The masses of 14 ground states and two isomers were measured with relative mass uncertainties down to 1×10−7 using the multiple-reflection time-of-flight mass spectrometer of the FRS-IC, including the first direct mass measurements of $^{98}$Cd and $^{97}$Rh. A new QEC=5437±67 keV was obtained for $^{98}$Cd, resulting in a summed Gamow-Teller (GT) strength for the five observed transitions (0+…
Optical and structural properties of Al 2 O 3 /ZnO nanolaminates deposited by ALD method
2014
International audience; We report on the investigation of optical and structural properties of Al2O3/ZnO nanolaminates. The nanolaminates were deposited on Si and glass substrates by Atomic layer deposition method. Structural properties of nanolaminates were studied by SEM, GIXRD, and AFM. Optical characterization was performed by transmittance and photoluminescence spectroscopy. Complex analysis of monolayer properties was done by ellipsometry. Optical constants for Al2O3 and ZnO monolayer were calculated.
Covalent Protein Binding of Vinyl Chloride Metabolites During Co-Incubation of Freshly Isolated Hepatocytes and Hepatic Sinusoidal Cells of Rats
1983
Proteins of isolated rat hepatic sinusoidal cells incubated with 14C-vinyl chloride, rat liver microsomes and an NADPH-regenerating system were alkylated by vinyl chloride metabolites formed by microsomes. This suggests that reactive vinyl chloride metabolites can penetrate sinusoidal cells. Protein alkylation in isolated hepatic sinusoidal cells was higher when these were co-incubated with isolated hepatocytes, indicating that reactive vinyl chloride metabolites formed by hepatocytes are stable enough to diffuse out of hepatocytes into sinusoidal cells. Glutathione added to the incubation medium inhibited the covalent protein binding of vinyl chloride metabolites in sinusoidal cells as wel…
Role of NSCLC exosomes in osteoclast differentiation
2017
Bone metastases represent a frequent cause of morbidity and mortality in patients suffering many types of cancer including breast, kidney, and lung. Non-small cell lung cancer (NSCLC) is one of the most commonly diagnosed neoplasia. About 70% of NSCLC patients develop bone metastasis during the course of disease or at diagnosis. NSCLC frequently induces osteolytic metastases associated to bone lesions or destruction. NSCLC cells induce the release of factors that alter the regulatory networks existing between osteoblast and osteoclasts, modifying the normal balance of the receptor activator of NF-kB ligand (RANKL) and osteoprotegerin (OPG). RANKL is essential during the differentiation stag…
Mutations in p53 Gene Exons in a Sample from the South of Spain in Oral Cancer
2021
[Background+ Cancer is a genetic disease caused by mutations in DNA and epigenetic alterations that control gene expression. The majority of epidermoid carcinomas develop within the fields of epithelial genetic alterations. The mechanisms underlying tumorigenesis of epidermoid carcinoma are as yet unknown; therefore, precise identification of the risk factors is needed.
Hexagonal Microparticles from Hierarchical Self-Organization of Chiral Trigonal Pd3L6 Macrotetracycles
2021
Construction of structurally complex architectures using inherently chiral, asymmetric, or multi-heterotopic ligands is a major challenge in metallosupramolecular chemistry. Moreover, the hierarchical self-organization of such complexes is unique. Here, we introduce a water-soluble, facially amphiphilic, amphoteric, chiral, asymmetric, and hetero-tritopic ligand derived from natural bile acid, ursodeoxycholic acid. We show that via the supramolecular transmetalation reaction, using nitrates of Cu(II) or Fe(III), and subsequently Pd(II), a superchiral Pd3L6 complex can be obtained. Even though several possible constitutional isomers of Pd3L6 could be formed, because of the ligand asymmetry a…
Peroxisome Proliferator-Activated Receptors and Atherosclerosis
2011
The peroxisome proliferator-activated receptors (PPARs) represent the family of 3 nuclear receptor isoforms-PPARα, -γ, and -δ/β, which are encoded by different genes. As lipid sensors, they are primarily involved in regulation of lipid metabolism and subsequently in inflammation and atherosclerosis. Atherosclerosis considers accumulation of the cells and extracellular matrix in the vessel wall leading to the formation of atherosclerotic plaque, atherothrombosis, and other vascular complications. Besides existence of natural ligands for PPARs, their more potent synthetic ligands are fibrates and thiazolidindiones. Future investigations should now focus on the mechanisms of PPARs activation, …
