In higher plants, most of the above-ground part ultimately derives from small populations of mitotic cells, called the shoot apical meristem (SAM). The SAM is initially formed during embryogenesis, when the basic body architecture of a plant is established (Jürgens, 1995). Once formed, the SAM plays central roles in postembryonic shoot organ formation. The SAM generates stems, leaves, and flora...
To measure the affective responses during high-intensity and moderate-intensity exercises, single-item questionnaires Feeling Scale (FS) Felt Arousal (FAS) are often used. The aim of present study was to examine validation German versions FS FAS by Maibach et al. (2020) for autogenic training (AT), which is an exercise addressing lowest end physical activation. Therefore, 224 participants (135 ...
Antipsychotic medications are associated with weight gain and adverse metabolic effects that complicate the treatment and management of schizophrenia. Olanzapine (OLZ) in particular is associated with significant weight gain and adverse metabolic effects. The present Phase 1, proof of concept, multicenter, randomized, double-blind, placebo-controlled study investigated the safety and effect on ...
OBJECTIVE To determine predictors of systolic anterior motion and left ventricular outflow tract obstruction (SAM/LVOTO) after mitral valve repair (MVRep) in patients with myxomatous mitral valve disease. BACKGROUND Mechanisms for the development of SAM/LVOTO after MVRep have been described; however, predictors of this complication have not been explored. We hypothesize that pre-MVRep transes...
Methionine restriction extends the lifespan of various model organisms. Limiting S-adenosyl-methionine (SAM) synthesis, the first metabolic reaction of dietary methionine, extends longevity in Caenorhabditis elegans but accelerates pathology in mammals. Here, we show that, as an alternative to inhibiting SAM synthesis, enhancement of SAM catabolism by glycine N-methyltransferase (Gnmt) extends ...
SAM (S-adenosylmethionine, also known as AdoMet) is well known as the methyl donor for the majority of methyltransferases that modify DNA, RNA, histones and other proteins, dictating replicational, transcriptional and translational fidelity, mismatch repair, chromatin modelling, epigenetic modifications and imprinting, which are all topics of great interest and importance in cancer research and...
RNA-based vaccines have recently emerged as a promising alternative to the use of DNA-based and viral vector vaccines, in part because of the potential to simplify how vaccines are made and facilitate a rapid response to newly emerging infections. SAM vaccines are based on engineered self-amplifying mRNA (SAM) replicons encoding an Ag, and formulated with a synthetic delivery system, and they i...
The supplementation of S-adenosylmethionine (SAM) to germination medium stimulated the accumulation of [14C]uracil from the medium into germinating cells, as well as its incorporation into ribonucleic acid during germination and outgrowth of ascospores of Saccharomyces cerevisiae. In addition to uracil, the accumulation of leucine, cytosine, serine, and methionine was also stimulated by the ext...
The enzyme S-adenosylmethionine (SAM) synthetase, the Escherichia coli metK gene product, produces SAM, the cell's major methyl donor. We show here that SAM synthetase activity is induced by leucine and repressed by Lrp, the leucine-responsive regulatory protein. When SAM synthetase activity falls below a certain critical threshold, the cells produce long filaments with regularly distributed nu...
BACKGROUND Severe acute malnutrition (SAM) affects almost all organs and has been associated with reduced intestinal absorption of medicines. However, very limited information is available on the pharmacokinetic properties of antimalarial drugs in this vulnerable population. We assessed artemether-lumefantrine (AL) clinical efficacy in children with SAM compared to those without. METHODS Chil...
