Day-night differences in the sensitivity of adrenoceptors in the Syrian hamster pineal gland: an in vivo iontophoretic study.
1989
Abstract Investigations on the regulation of pineal melatonin synthesis in the Syrian hamster revealed distinct differences compared to this well-understood mechanism in rat. E.g., a circadian profile of pineal norepinephrine (NE) is absent, there is no β-adrenoceptor sensitivity during daytime and adrenergic receptor supersensitivity is not easily achieved. To elucidate the action of NE on pineal receptor sites, the effects of iontophoretic application of adrenergic compounds on spontaneous electrical discharge rates of pinealocytes were investigated during day- and nighttime. Following application of either NE, isoproterenol or clonidine, cells were activated, inhibited or not affected. W…
Doliholu identifikācija un to līmeņu salīdzināšana žurku nierēs pēc poliprenolu un atorvastatīna ievadīšanas
2017
Latvijā poliprenoli tiek tirgoti kā uztura bagātinātāji, bet nav daudz zinātnisku pētījumu par to farmakoloģisko iedarbību. Iepriekšējie pētījumi in vivo ir apliecinājuši poliprenolu spēju samazināt statīnu izraisīto muskuļu vājumu laboratorijas dzīvniekiem. Darbojoties kā HMG-CoA reduktāzes inhibitori, statīni nobloķē mevalonskābes sintēzi un, iespējams, arī Q10, poliprenolu un doliholu sintēzi, un tiek pieļauts, ka muskuļu vājums ir tieši šo savienojumu līmeņu samazinājuma dēļ. Iespējams, ka eksogēni ievadīti poliprenoli veicina doliholu sintēzi. Darba mērķis ir ar šķidruma hromatogrāfijas masspektrometrijas (lidojuma laika (TOF)) metodi izpētīt, kāda tipa doliholi atrodas žurku nierēs, i…
Tectonic Sustainable Building Design for the Development of Renovation Scenarios – Analysis of ten European renovation research projects
2018
The investigation of 10 European building renovation research projects presented in this paper demonstrates that recent research in this field is currently centralized around quantifiable objectives i.e. development of energy efficient renovation scenarios, whereas the more qualitative objectives in renovation projects such as aesthetics, identity and/or social dimensions are rarely addressed. Furthermore, the result of this investigation together with the recent researches about the current practice of building renovation indicates that many of renovated buildings, which now are claimed to be sustainable are not addressing all aspects of a conventional definition of sustainability. Lastly,…
Phase separation of symmetric polymer mixtures in a common good solvent in the semidilute concentration regime
1994
Monte Carlo simulations of lattice models of binary (AB) symmetric polymer mixtures (chain lengthsN A=N B=N) in a common good solvent are carried out and the phase diagrams and critical properties of the unmixing transitions are estimated and interpreted in terms of recent theories. Polymers are modeled by self-avoiding walks of lengthN=16, 32 and 64 on the simple cubic lattice. Data for vacancy concentrations of φV=0.6, 0.8 and 0.85 are analyzed. It is shown that forN=16, φV=0.85 no phase separation occurs, down to the lowest temperature, while forN=32, φV=0.85 still phase separation occurs but no longer is complete. Our results are compatible with a scaling theory based on a “renormalizat…
Critical behavior of a tumor growth model: directed percolation with a mean-field flavor.
2012
We examine the critical behaviour of a lattice model of tumor growth where supplied nutrients are correlated with the distribution of tumor cells. Our results support the previous report (Ferreira et al., Phys. Rev. E 85, 010901 (2012)), which suggested that the critical behaviour of the model differs from the expected Directed Percolation (DP) universality class. Surprisingly, only some of the critical exponents (beta, alpha, nu_perp, and z) take non-DP values while some others (beta', nu_||, and spreading-dynamics exponents Theta, delta, z') remain very close to their DP counterparts. The obtained exponents satisfy the scaling relations beta=alpha*nu_||, beta'=delta*nu_||, and the general…
A new observable to measure the top-quark mass at hadron colliders
2013
A new method to measure the top-quark mass in high energetic hadron collisions is presented. We use theoretical predictions calculated at next-to-leading order accuracy in quantum chromodynamics to study the ( normalized) differential distribution of the t (t) over bar + 1-jet cross section with respect to its invariant mass root s(t (t) over barj). The sensitivity of the method to the top-quark mass together with the impact of various theoretical and experimental uncertainties has been investigated and quantified. The new method allows for a complementary measurement of the top-quark mass parameter and has a high potential to become competitive in precision with respect to established appr…
P1003STUDY DESIGN OF THE ROTATION FOR OPTIMAL TARGETING OF ALBUMINURIA AND TREATMENT EVALUATION (ROTATE-3): A ROTATION STUDY OF DIFFERENT ALBUMINURIA…
2020
Abstract Background and Aims Patients with diabetic kidney disease show a wide variability in their response to established and new treatments. SGLT2 inhibitors have also shown to slow the progression of kidney disease. Some studies have also shown kidney benefits for Mineralocorticoid Receptor Antagonists (MRA). A large outcome trial with the MRA finerenone is currently ongoing to assess effects of this MRA on major kidney outcomes. The individual trials will solve the issue whether a patient may have benefit from an SGLT2 inhibitor or MRA, but they do not address the key question which of the two or their combination is better to reduce albuminuria for each individual patient. Therefore, …

Chloroplast morphology and pyrenoid ultrastructural analyses reappraise the diversity of the lichen phycobiont genus Trebouxia (Chlorophyta)
2022
Abstract Trebouxiophyceae is a wide class of green algae comprising coccoid and elliptic unicells, filaments, blades and colony-forming species that occur in diverse terrestrial and aquatic environments. Within this class, the genus Trebouxia Puymaly is among the most widespread lichen phycobionts worldwide. However, the 29 formally described species based on the combination of morphological traits and genetic diversity woefully underrepresented the overall species-level diversity recognized in the genus. In Trebouxia, reliable differentiation and characterization of the species-level lineages can be achieved by studying the diversity of key diagnostic features of pyrenoid ultrastructure an…
