Abstract
BackgroundEveryone knows that COVID-19 not only has a severe effect on the pulmonary system, but also triggers a whole cascade of autoimmune reactions. The study of the effect of the pro-inflammatory cytokine - interleukin 6 (IL6) on the clinical course of patients with ankylosing spondylitis (AS) undergoing COVID-19 is an important problem in rheumatology..ObjectivesTo study the significance of the pro-inflammatory cytokine-IL-6 on the clinical features of the course of AS in patients who have undergone COVID-19.MethodsIn the period from 2020-2021, 44 patients with a diagnosis (AS) were hospitalized in the City Clinical Hospital # 3 of Tashkent city. The patients were divided into two groups: Group I - 20 patients with AS who underwent COVID-19 and Group II of 24 patients with no history of AS who had COVID-19 infection. The average age of patients in group I was 32 ± 4.1 years and in group II - 36.5 ± 5.2 years. All patients underwent clinical and laboratory studies, including studies of serum IL-6 levels. Disease activity was assessed using the BASDAI and ASDAS scales, pain was assessed using a numerical rating scale (NRS), and peripheral joint damage was assessed by the presence of pain and swelling in 44 joints. All patients underwent PCR, as well as ELISA-IHLA tests for the presence of antibodies to COVID-19.ResultsClinical examination of the patients revealed the presence of pain in the spine, which was assessed using the numerical rating scale – (NRS) in group I it was 8.5 ± 1.2 points and 5.9 ± 2.3 points in patients of group II. Examination of peripheral joints showed an average number of painful joints (PJ) of 16.9 ± 3.2 in group I and 8.6 ± 2.7 in group II, the number of swollen joints (NSJ) 8.8 ± 2.1 in group I and 4.2 ± 1.7 in group II. group. The study of AS activity using the BASDAI scale showed an average level of 5.1 ± 1.7 points in group I and 4.4 ± 2.1 points in group II. And the study of activity on the ASDAS scale showed an average level of 4.0 ± 1.7 points in group I and 2.5 ± 0.8 points in group II, which indicates a very high activity of the pathological process in group I and medium-high activity in group II. The IL-6 level in group I was 10.2 ± pg / mL, 4.2 pg / mL in group II and 1.39 pg / mL in the control group.Conclusion1. The clinical course of AS in patients who have undergone COVID-19 is characterized by a more pronounced disease activity according to the BASDAI and ASDAS scales, a high intensity of pain syndrome according to a NRS, as well as a high level of IL-6.2. A high level of IL-6 in group I indicates the impact of COVID-19 on the course, activity and severity of the autoimmune process in patients with AS, which is many times higher than in patients of group II, which allows us to consider it as a biomarker of damage to the articular and connective tissue in this infection.References[1]Brito CA, Paiva JG, Pimentel FN, et al.

Abstract
Mechanisms that regulate the bi-directional transport of mitochondria in neurons for maintaining functional synaptic connections are poorly understood. Here, we show that in the pre-synaptic sensory neurons of the Aplysia gill withdrawal reflex, the formation of functional synapses leads to persistent enhancement in the flux of bi-directional mitochondrial transport. In the absence of a functional synapse, activation of cAMP signaling is sufficient to enhance bi-directional transport in sensory neurons. Furthermore, persistent enhancement in transport does not depend on NMDA and AMPA receptor signaling nor signaling from the post-synaptic neuronal cell body, but it is dependent on transcription and protein synthesis in the pre-synaptic neuron. We identified ∼4,000 differentially enriched transcripts in pre-synaptic neurons, suggesting a long-term change in the transcriptional program produced by synapse formation. These results provide insights into the regulation of bi-directional mitochondrial transport for synapse maintenance.

Abstract
A major challenge in neurobiology is to understand the molecular underpinnings of neural circuitry that govern a specific behavior. Once the specific molecular mechanisms are identified, new therapeutic strategies can be developed to treat abnormalities in specific behaviors caused by degenerative diseases or aging of the nervous system. The marine snail Aplysia californica is well suited for the investigations of cellular and molecular basis of behavior because neural circuitry underlying a specific behavior could be easily determined and the individual components of the circuitry could be easily manipulated. These advantages of Aplysia have led to several fundamental discoveries of neurobiology of learning and memory. Here we describe a preparation of the Aplysia nervous system for the electrophysiological and molecular analyses of individual neurons. Briefly, ganglion dissected from the nervous system is exposed to protease to remove the ganglion sheath such that neurons are exposed but retain neuronal activity as in the intact animal. This preparation is used to carry out electrophysiological measurements of single or multiple neurons. Importantly, following the recording using a simple methodology, the neurons could be isolated directly from the ganglia for gene expression analysis. These protocols were used to carry out simultaneous electrophysiological recordings from L7 and R15 neurons, study their response to acetylcholine and quantitating expression of CREB1 gene in isolated single L7, L11, R15, and R2 neurons of Aplysia.
