Rewriting History in Integrable Stochastic Particle Systems.

Many integrable stochastic particle systems in one space dimension (such as TASEP-Totally Asymmetric Simple Exclusion Process-and its -deformation, the -TASEP) remain integrable if we equip each particle with its own speed parameter. In this work, we present intertwining relations between Markov transition operators of particle systems which differ by a permutation of the speed parameters. These relations generalize our previous works (Petrov and Saenz in Probab Theory Relat Fields 182:481-530, 2022), (Petrov in SIGMA 17(021):34, 2021), but here we employ a novel approach based on the Yang-Baxter equation for the higher spin stochastic six vertex model.

[The Russian consensus on the treatment of intrahepatic cholangiocarcinoma].

The Russian consensus on the treatment of intrahepatic cholangiocarcinoma was prepared by the group of experts consisting of surgeons, interventional radiologists, radiation therapists and oncologists. The purposes of this consensus are clarification and consolidation of opinions of multidisciplinary team on the following issues of management of patients with intrahepatic cholangiocarcinoma: indications for surgical treatment, features of therapeutic tactics for mechanical jaundice, technical aspects of liver resection, prevention of post-resection liver failure, indications for liver resection using transplantation technologies, laparoscopic and robot-assisted liver resection, perioperative systemic chemotherapy, local non-resection/non-radiotherapy methods of treatment, radiotherapy, follow-up and choice of treatment for recurrence.

The life-saving benefit of dexamethasone in severe COVID-19 is linked to a reversal of monocyte dysregulation.

Dexamethasone is a life-saving treatment for severe COVID-19, yet its mechanism of action is unknown, and many patients deteriorate or die despite timely treatment initiation. Here, we identify dexamethasone treatment-induced cellular and molecular changes associated with improved survival in COVID-19 patients. We observed a reversal of transcriptional hallmark signatures in monocytes associated with severe COVID-19 and the induction of a monocyte substate characterized by the expression of glucocorticoid-response genes.

Effect of Aging on Tensile and Chemical Properties of Polylactic Acid and Polylactic Acid-Like Polymer Materials for Additive Manufacturing.

Additive manufacturing, with its fast development and application of polymeric materials, led to the wide utilization of polylactic acid (PLA) materials. As a biodegradable and biocompatible aliphatic polyester, produced from renewable sources, PLA is widely used in different sectors, from industry to medicine and science. The aim of this research is to determine the differences between two forms of the PLA material, i.

A Comprehensive Mechanical Examination of ABS and ABS-like Polymers Additively Manufactured by Material Extrusion and Vat Photopolymerization Processes.

Additive manufacturing technologies have developed rapidly in recent decades, pushing the limits of known manufacturing processes. The need to study the properties of the different materials used for these processes comprehensively and in detail has become a primary goal in order to get the best out of the manufacturing itself. The widely used thermoplastic polymer material acrylonitrile butadiene styrene (ABS) was selected in the form of both filaments and ABS-like resins to investigate and compare the mechanical properties through a series of different tests.

[Indocyanine green in liver tumor resection].

Primary liver cancer and colorectal cancer liver metastases are among the leading causes of cancer-related mortality worldwide. Surgery is one of the main methods of treatment to achieve the best results in overall and recurrence-free survival. The main objectives in this surgery are preoperative planning, assessment of functional viability of liver parenchyma and total resection with low complication rate.

[Isolated endovascular liver chemoperfusion for liver metastases of uveal melanoma].

Isolated hepatic perfusion is one of the possible approaches for unresectable liver metastases of uveal melanoma. This technique is rare in modern oncology because of extremely difficult technique and high risk of intra- and postoperative complications. Thus, minimizing surgical trauma and increasing safety and reproducibility of this technique are important.

The amplified compressed pulses, with a spectral bandwidth of 13.

CD4 T cell calibration of antigen-presenting cells optimizes antiviral CD8 T cell immunity.

Antiviral CD8 T cell immunity depends on the integration of various contextual cues, but how antigen-presenting cells (APCs) consolidate these signals for decoding by T cells remains unclear. Here, we describe gradual interferon-α/interferon-β (IFNα/β)-induced transcriptional adaptations that endow APCs with the capacity to rapidly activate the transcriptional regulators p65, IRF1 and FOS after CD4 T cell-mediated CD40 stimulation. While these responses operate through broadly used signaling components, they induce a unique set of co-stimulatory molecules and soluble mediators that cannot be elicited by IFNα/β or CD40 alone.

Effect of Chitosan-Diosgenin Combination on Wound Healing.

The difficult-to-heal wounds continue to be a problem for modern medicine. Chitosan and diosgenin possess anti-inflammatory and antioxidant effects making them relevant substances for wound treatment. That is why this work aimed to study the effect of the combined application of chitosan and diosgenin on a mouse skin wound model.

Snail Mucus Protective Effect on Ethanol-Induced Gastric Ulcers in Mice.

Nowadays, an increased interest in natural compounds with preventive or therapeutic potential for various diseases has been observed. Given the involvement of oxidative stress in the pathogenesis of gastric ulcer (GU) and the wide range of bioactive compounds isolated from snails, this study aimed to investigate the protective effect of (Müller, 1774) mucus on ethanol-induced GUs. Male albino mice were divided into Control, Ethanol, Mucus + Ethanol and Mucus + Omeprazole treated groups.

Oxidative stress underlies the pathogenesis of many diseases, which determines the interest in natural substances with antioxidant properties. L. leaves are well known and widely used in the pharmaceutical industry, but the therapeutic properties of the seeds are less studied.

Complement activation induces excessive T cell cytotoxicity in severe COVID-19.

Severe COVID-19 is linked to both dysfunctional immune response and unrestrained immunopathology, and it remains unclear whether T cells contribute to disease pathology. Here, we combined single-cell transcriptomics and single-cell proteomics with mechanistic studies to assess pathogenic T cell functions and inducing signals. We identified highly activated CD16 T cells with increased cytotoxic functions in severe COVID-19.

Neoadjuvant chemoradiotherapy for locally advanced rectal cancer with peritumoral abscesses and fistulas.

Photobiomodulation with 590 nm Wavelength Delays the Telomere Shortening and Replicative Senescence of Human Dermal Fibroblasts .

Cellular senescence is one of the major factors contributing to the aging process. Photobiomodulation (PBM) is known to trigger an array of cellular responses, but there are no data on how it affects the process of cellular senescence. In this study, we analyze the effect of PBM on the cellular senescence and telomere dynamics.

Myosin-VIIa is expressed in multiple isoforms and essential for tensioning the hair cell mechanotransduction complex.

Mutations in myosin-VIIa (MYO7A) cause Usher syndrome type 1, characterized by combined deafness and blindness. MYO7A is proposed to function as a motor that tensions the hair cell mechanotransduction (MET) complex, but conclusive evidence is lacking. Here we report that multiple MYO7A isoforms are expressed in the mouse cochlea.
