  2021-04-21

  

  The presence of H+-PPases in parasitic protists raises the question of the physiological role of these proteins. So far, they had been extensively characterized mainly in higher plants, and some prokaryotes [1], [2], [3], [4], [5], [6], [7], [16], [20]. A common feature to all these organisms is tha

  Introduction Quassinoids are natural products formed through the oxidative degradation of triterpene derivatives with anti-inflammatory, antimicrobial, antineoplastic, and antiplasmodial effects (Chakraborty and Pal, 2013; Houël et al., 2013). They are characteristic ingredients of the family Simar

  The aim of this study was to use molecular methods to characterise C. difficile isolates circulating in the Czech Republic from 2013 to 2015. Material and methods Discussion During a three-year period (2013–2015) a total of 32 hospitals voluntarily participated in this project, but only 11 ho

  Acknowledgments Introduction Cholesterol is an essential lipid for the development, growth, and wellbeing of humans. In newborn children, cord blood cholesterol concentration is 1.5 mmol/l, on average [[1], [2], [3], [4]]. During the first year of life, cholesterol concentration in serum incre

  In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B. An

  Methods Results First, we compared Aβ plaque number, Aβ concentration, and neurobehavior functions between naive APP/PS1 and APP/PS1xEP1−/− mice. Significantly lower Aβ burden in APP/PS1xEP1−/− mice was evidenced by fewer plaques in the hippocampal area and a lower concentration of soluble Aβ42

  First of all, it should be emphasized that, although cPLA2α manifests a marked selectivity for phospholipids that contain AA at the sn-2 position, this does not mean in any way that, in cells, the enzyme cannot hydrolyze other fatty acyl residues to a significant extent even if this occurs at a lowe

  In summary, we investigated the fluoride sensitivity of different S. mutans strains in terms of enolase activity. Lower enolase activity was not always associated with lower S. mutans growth in cultures with NaF. Gene analysis showed that UA130 and NCH105 both have enolase point mutations. Unique am

  To study the effect of DDR inhibition by imatinib, nilotinib and dasatinib in a cellular environment we generated DDR1 and DDR2 expressing HEK293 cell lines by stable transfection. Of the five DDR1 splice variants we focused on the 1b variant whose over-expression has been associated with pulmonary

  RING-type E3s and their substrates There is enormous diversity in substrate ubiquitination and its regulation, as the targets of RING-type E3s are incredibly varied. RING-type E3s are implicated as tumor suppressors, oncogenes, and mediators of endocytosis, and play critical roles in complex mult

  In a study carried out by Aunis et al. the properties of soluble DBH and membrane bound were examined [23]. The membrane bound enzyme was shown in ion channels to the soluble form to have thermal denaturation at higher temperatures of 43.5–44°C. Similar discontinuities in the Arrhenius plots were o
