Puromycin (Puro) is a natural aminonucleoside antibiotic that inhibits protein synthesis by its incorporation into elongating peptide chains. The unique mechanism of Puro finds diverse applications in molecular biology, including the selection of genetically engineered cell lines, in situ protein synthesis monitoring, and studying ribosome functions. However, the key step of Puro biosynthesis remains enigmatic.

Unlabelled: Chronic arterial insufficiency of lower limbs (CAILL) is a common cardiovascular disease that affects 200 million subjects worldwide: from 4 to 12% of people aged 55-70 years and 20% - over 70 years. The cause of blood circulation disorder in this disease is usually a complex of pathological changes including abnormality of vessel walls' anatomical structure or integrity, disorder of blood rheological properties and alterations of its thrombotic potential. Thus, the therapy of patients with CAILL aiming at hemostasis and, in particular, platelets' aggregation is one of the most urgent problems of medicine.

SMA is a rare autosomal recessive neurodegenerative motor neuron disease in which wide phenotypic variability has been described. The rate of increase in neurological deficit and the severity of the disease is mainly determined by the amount of functional SMN (Survival of Motor Neuron) protein.
View Article and Find Full Text PDFAging is known to be associated with a decline in interoceptive abilities and changes in emotional processing, including alexithymia. As the brain areas supporting interoceptive awareness participate in the perception of emotion, we suggested that interoceptive decline and alexithymia in older adults may share common neural ground. To test this hypothesis, we administered functional magnetic resonance imaging-based heartbeat detection task to 62 adults of diverse ages (range 18-73) and evaluated a larger sample of older and younger adults using questionnaires characterizing interoceptive sensibility, alexithymia, and depressive attitudes.

Several pathological consequences, including cancer, Alzheimer's disease, autoimmune diseases, and many others, are mostly driven by inflammation and Nrf2, and its negative regulator, the E3 ligase adaptor Kelch-like ECH-associated protein 1 (Keap1), plays a crucial role in maintaining redox status, the expression of antioxidant genes, and the inflammatory response. Interestingly, tuning the Nrf2/antioxidant response element (ARE) system can affect immune-metabolic mechanisms.

Unlabelled: Obstructive uropathy in children is predominantly urinary system malformation and one of the leading causes of chronic renal failure. Antenatal ultrasound can detect obstructive uropathy in infants. It is important to conduct diagnostics not only to identify the obstruction level in urinary system, but to assess renal function, renal blood flow and urination.

This article presents the findings regarding neuroregeneration and the structure of the nervous system based on antibody labeling of serotonin and FMRFamide. We propose the main stages of central nervous system neurogenesis during regeneration: single nerve fibers, a loop structure, and neurons in the brain and segmental ganglia.

Objective: To study the efficacy of ocrelizumab (OCR) and natalizumab (NAT) using indicators of activity and progression in patients with highly active multiple sclerosis (HAMS) during the first year of therapy in real clinical practice.
Material And Methods: The study included 110 patients with HAMS and 13 patients with rapidly progressive MS (RPMS), aged 19 to 60 years, who received monoclonal antibody (MAT) therapy for 12 months. Group 1 consisted of 77 patients receiving NAT therapy, group 2 of 46 patients receiving OCR therapy.
Introduction: Oxidative stress considered to be the main cause of male infertility. Surgical treatment of varicocele and elimination of the inflammatory process in the male accessory glands can help reduce the level of oxidative stress, however, in most cases, antioxidant therapy is additionally prescribed. Currently, much attention is paid to regulatory peptides as a component of antioxidant therapy due to their antioxidant, anti-inflammatory and immunomodulatory properties.

The impact of timing in which antibiotic exposure occurs was investigated by treating mice from days 5-9 with amoxicillin or azithromycin, two of the most commonly prescribed medications in children. Both early-life antibiotic regimens disrupted Peyer's patch development and immune cell abundance, with a sustained decrease in germinal center formation and diminished intestinal immunoglobulin A (IgA) production.

However, there are still huge gaps in our knowledge on the organization and functioning of their nervous system. Most of the recent studies have focused on the distribution of serotonin and FMRFamide, while the data about many other basic neurotransmitters such as histamine (HA) and gamma-aminobutyric acid (GABA) are scarce.

The attacker profile is a set of attributes characterising an attacker and their behaviour. This paper analyzes the research in the area of attacker modelling and presents the analysis results as a classification of attacker models, attributes and risk analysis techniques that are used to construct the attacker models.

Photoreceptors with different spectral sensitivities serve different physiological and behavioral roles. We hypothesized that such functional evolutionary optimization could also include differences in phototransduction dynamics. We recorded elementary responses to light, quantum bumps (QBs), of broadband green-sensitive and ultraviolet (UV)-sensitive photoreceptors in the cockroach, Periplaneta americana, compound eyes using intracellular recordings.

Mediator also links transcription and nucleotide excision repair (NER) via a direct contact with Rad2/ERCC5(XPG) endonuclease. In this work, we analyzed the genome-wide distribution of Rad26/ERCC6(CSB) and Rad1-Rad10/ERCC4(XPF)-ERCC1, addressing the question of a potential link of these proteins with Mediator and Pol II in yeast Our genomic analyses reveal that Rad1-Rad10 and Rad26 are present on the yeast genome in the absence of genotoxic stress, especially at highly transcribed regions, with Rad26 binding strongly correlating with that of Pol II.
View Article and Find Full Text PDFAging is associated with decreased functional connectivity in the main brain networks, which can underlie changes in cognitive and emotional processing. Neurofeedback is a promising non-pharmacological approach for the enhancement of brain connectivity. Previously, we showed that a single session of infra-low frequency neurofeedback results in increased connectivity between sensory processing networks in healthy young adults.
View Article and Find Full Text PDFInteroception is critically important for allostatic adaptation and emotional regulation, and aberrant interoceptive processing is increasingly recognized to be involved in the pathogenesis of neurological, psychiatric and cardiovascular diseases. Despite the fact that interoceptive abilities decline with age, the corresponding neural correlates and clinical consequences of these age-related changes have yet to be discovered. We present a dataset that contains task-based functional neuroimaging data from 50 adults aged 40-65 years and 12 adults aged 18-25 years who performed an fMRI-based heartbeat-detection task.

In such a situation, the onset of pregnancy in the natural cycle is impossible - even with a completely preserved reproductive function in a woman. As an active substance in the recovery of men with chronic prostatitis associated with secondary infertility, we proposed oxidised dextran in the form of a pharmaceutical composition, which was developed at Federal Research Centre for Fundamental and Translational Medicine, Novosibirsk, Russia; and produced by ANDROEXPERT Research and Manufacturing Company LTD, Novosibirsk, Russia.
