[Peptide regulation of cellular aging.].

Cellular aging is the inability of structures to proliferate (further division) and repair damage while maintaining metabolic activity. The key well-known factors of cellular aging are the processes of DNA damage, telomere shortening, the development of oxidative stress and epigenetic changes. The above factors provoke the development of a pro-inflammatory environment, leading to errors in gene expression and metabolic dysregulation, thereby affecting the development of age-related diseases that contribute to pathological changes in the functions of tissues and organs.

The stem canker disease eastern filbert blight (EFB), caused by , is a major impediment of European hazelnut () production in the United States. While most European hazelnut cultivars are highly susceptible to the pathogen, which remains confined to North America, EFB resistant and tolerant genotypes occur in the gene pool at low frequency. At Rutgers University, New Brunswick, NJ, USA, 5,226 trees were grown from open pollinated seeds collected from Russia, Crimea, Poland, Turkey, Estonia, Latvia, Lithuania, Moldova, Azerbaijan, Italy, and the Republic of Georgia between 2002 to 2010.

The Rey Auditory Verbal Learning Test: adaptation into Russian and a new digital "RAVLT World".

The Rey Auditory Verbal Learning Test (RAVLT) is a classic test used to assess episodic verbal memory in research and clinical practice. We aimed to adapt the RAVLT materials into Russian, provide performance norms across the adult lifespan for the Russian adaptation, and develop a mobile application for automated RAVLT administration across languages. We created three psycholinguistically matched alternative versions of the RAVLT materials in Russian and incorporated them into a new tablet application.

An α7 nicotinic and GABA receptor-mediated pathway controls acetylcholine release in the tripartite neuromuscular junction.

Terminal Schwann cells (TSCs) are capable of regulating acetylcholine (ACh) release at the neuromuscular junction (NMJ). We have identified GABA as a gliotransmitter at mouse NMJs. When ACh activates α7 nicotinic ACh receptor (nAChRs) on TSCs, GABA is released and activates GABA receptors on the nerve terminal that subsequently reduce ACh release.

A New Empirical Equation to Take Into Account the Influence of Ionic Strength on Electrophoretic Mobility and Determination of Binding Constants of Ester Betulin Derivatives With Sulfated β-Cyclodextrin by Affinity Capillary Electrophoresis.

An empirical equation relating electrophoretic mobility and ionic strength was proposed. The equation includes a number of parameters that are found using the mobilities of reference ions: two coefficients in the numerator describing the linear relationship of the multiplier in front of the square root of the ionic strength with the product of the ion mobility in the background electrolyte (BGE) without additives by the modulus of the charge number, raised to a certain power, and also the multiplier in the denominator before the square root of the ionic strength. The proposed equation was tested using the mobilities measured in BGEs with the addition of sodium chloride to adjust ionic strength and sulfated β-cyclodextrin (S-β-CD) for 11 anions with charge numbers from -1 to -4.

Trojan horse peptide conjugates remodel the activity spectrum of clinical antibiotics.

Infections caused by gram-negative pathogens continue to be a major risk to human health because of the innate antibiotic resistance endowed by their unique cell membrane architecture. Nature has developed an elegant solution to target gram-negative strains, namely by conjugating toxic antibiotic warheads to a suitable carrier to facilitate the active import of the drug to a specific target organism. Microcin C7 (McC) is a Trojan horse peptide-conjugated antibiotic that specifically targets enterobacteria by exploiting active import through oligopeptide transport systems.

The Ground State of Multispin Systems Based on Verdazyl and Nitrene Radicals: An EPR and Quantum-Chemical Study.

In this study, low-temperature EPR spectroscopy and quantum-chemical techniques were employed to investigate multispin systems─1,5-diphenyl-3-(3-nitrenophenyl)-6-oxoverdazyl and 1,5-diphenyl-3-(4-nitrenophenyl)-6-oxoverdazyl─that contain a nitrene center at either a - or -position, respectively. Ground states and magnetic zero-field splitting (ZFS) parameters of these multispin systems were determined by experimental and computational methods. The results indicated that the high-spin quartet state is a ground state, and the quartet-doublet energy gap is close to 10 kcal/mol for the -position of the nitrene group, with ZFS parameters = 0.

Ultrastructural Remodeling of Cardiomyocytes in Postinfarction Myocardium of Rats in the Late Stages of the Disease.

Identifying factors that contribute to the transition to the dilated phase in cardiac ischemia is a critical challenge in heart failure treatment. Currently, no effective therapies exist for this ischemic complication, and the mechanisms driving left ventricular dilatation during chronic post-infarction remodeling remain poorly understood. One potential pathological process leading to ventricular dilatation involves specific compensatory rearrangements in the border zone adjacent to the infarct, which isolates the intact myocardium from inflammation at the scar edge.

Coefficients in Taylor's law increase with the time scale of water clarity measurements in a global suite of lakes.

Identifying the scaling rules describing ecological patterns across time and space is a central challenge in ecology. Taylor's law of fluctuation scaling, which states that the variance of a population's size or density is proportional to a positive power of the mean size or density, has been widely observed in population dynamics and characterizes variability in multiple scientific domains. However, it is unclear if this phenomenon accurately describes ecological patterns across many orders of magnitude in time, and therefore links otherwise disparate observations.

Lacustrine sedimentation patterns at the Northern Antarctic Peninsula and surroundings as a response to late Holocene and Modern Climate changes.

The Northern Antarctic Peninsula (NAP) and the West Antarctic Ice Sheet (WAIS) are likely to respond rapidly to climate changes by increasing the collapse of peripheral ice shelves and the number of days above 0 °C. These facts make this region a representative hotspot of the global sea level rise and the location of one of the global climate tipping points (thresholds in the Earth system whose changes may become irreversible, if exceeded). Understanding the climate evolution of the NAP, based on past evidences, may help infer its future scenario.
