Publications in plain English
Novel use of bisphosphonates to improve surgical outcomes in experimental bone tuberculosis.
Plain English This study examined the use of a drug called pamidronate to enhance bone healing after surgery for a type of bone infection caused by tuberculosis in rabbits.

Researchers found that in a specific type of pancreatic cancer cells (BxPC3), several genes increased their activity, such as NKX6.1 and NR5A2, by up to 2.5 times, while others like MUC1 decreased by 3 times. These changes indicate a link between PDX1 levels and cancer cell behavior, particularly in more aggressive cancer types, which could influence treatment strategies.
Who this helps: This helps patients with pancreatic cancer and their doctors in understanding how genetic factors affect cancer treatment options.
PDX1: A Unique Pancreatic Master Regulator Constantly Changes Its Functions during Embryonic Development and Progression of Pancreatic Cancer.
2017
Biochemistry. Biokhimiia
Vinogradova TV, Sverdlov ED
Plain English This study looked at the PDX1 protein, which is found only in the pancreas and has different roles during both the development of the pancreas and the progression of pancreatic cancer. Researchers found that PDX1 is a "master regulator" that performs many functions, sometimes even working against itself, which is important for understanding how pancreatic issues arise. Understanding how PDX1 works can help in developing new treatments for pancreatic cancer.

Krasavin M, Parchinsky V, Kantin G, Manicheva O, Dogonadze M +3 more
Plain English This study explored new compounds designed to fight resistant strains of tuberculosis, specifically focusing on a group of bacteria called Mycobacterium tuberculosis. Researchers found that three new compounds effectively inhibited growth of these bacteria at low concentrations (22-33 µM) while having little impact on other common infections. These findings are important because they offer potential new treatment options for patients suffering from multidrug-resistant tuberculosis.
Who this helps: This helps patients with multidrug-resistant tuberculosis.
Electrochemical Na+ and Ca2+ gradients drive coupled-clock regulation of automaticity of isolated rabbit sinoatrial nodal pacemaker cells.

Sirenko SG, Maltsev VA, Yaniv Y, Bychkov R, Yaeger D +3 more
Plain English This study looked at how sodium (Na+) and calcium (Ca2+) levels influence the heart's natural pacemaker cells, specifically in rabbits. The researchers found that when they inhibited a pump that usually helps control sodium and potassium levels, the sodium and calcium levels initially increased, leading to changes in the heart's electrical signals. Over time, these changes caused the timing of the heartbeats to become erratic and prolonged, indicating a complex relationship between these ions and heart rhythm.
Who this helps: This research helps doctors understand heart rhythm issues and how to better manage conditions related to heart pacemaker functions.
CaMKII-dependent phosphorylation regulates basal cardiac pacemaker function via modulation of local Ca2+ releases.

American journal of physiology. Heart and circulatory physiology
Li Y, Sirenko S, Riordon DR, Yang D, Spurgeon H +2 more
Plain English This study focused on how a specific protein called CaMKII affects the heart’s natural pacemaker, specifically in rabbit heart cells. Researchers found that the activation of CaMKII in these pacemaker cells was about twice as high as in regular heart cells, which led to significant increases in key protein activities important for heart rhythm. These findings are crucial because understanding this process can help improve treatments for heart rhythm disorders.
Who this helps: This helps patients with heart rhythm issues and cardiologists seeking better treatment options.
andgene promoters for cancer gene therapy: A comparative study.
2016
Oncology letters
Shepelev MV, Kopantzev EP, Vinogradova TV, Sverdlov ED, Korobko IV
Plain English This study looked at different gene promoters used in cancer therapies to find the best way to target tumor cells. Researchers tested human and mouse gene promoters in 10 human cancer types and found that the effectiveness of these promoters varied greatly, being similar in only 40% of the cases. They discovered that modifying certain promoters led to improved performance, suggesting the need for better promoters that can effectively target more types of tumors.
Who this helps: This helps researchers and doctors working on cancer gene therapies.
Experimental bladder regeneration using a poly-l-lactide/silk fibroin scaffold seeded with nanoparticle-labeled allogenic bone marrow stromal cells.

International journal of nanomedicine
Yudintceva NM, Nashchekina YA, Blinova MI, Orlova NV, Muraviov AN +9 more
Plain English In this study, researchers explored a new way to help rebuild bladder tissue using a special scaffold made from silk and a biodegradable material, along with bone marrow cells from other rabbits. They found that rabbits given this combination showed better integration of the tissue and healthier bladder function after 12 weeks compared to those that received a scaffold without the cells, with improvements in muscle and tissue regeneration observed. This work is important because it points to a promising method for repairing bladder defects that could lead to better treatments for patients with bladder injuries or diseases.
Who this helps: Patients with bladder injuries or conditions that affect bladder function.
[Preclinical and clinical trials of the new tuberculosis drug perchlozon].

Yablonskiy PK, Vinogradova TI, Levashev YN, Pavlova MV, Zilber EK +6 more
Plain English The study looked at a new tuberculosis (TB) drug called perchlozon to see how well it works and how safe it is for patients with respiratory TB. The trials showed that using perchlozon as part of treatment shortened the time it takes to show improvement in patients with drug-resistant TB, which is tougher to treat. This is important because TB caused by drug-resistant strains is becoming more common, and perchlozon offers hope for patients who have limited treatment options.
Who this helps: This helps patients with severe, drug-resistant tuberculosis.
