Intestinal inflammatory disorders, such as inflammatory bowel disease (IBD), are associated with increased pro-inflammatory cytokine secretion in the intestines. Furthermore, intestinal inflammation increases the risk of enteric cancer, which is a co…
Thymosin alpha1 (Tα1), an endogenous peptide first isolated from the thymic tissue in the mid-sixties, has gained considerable attention for its immunostimulatory activity that led to its application to diverse pathological conditions, including canc…
Prothymosin alpha (ProTα) is a highly conserved polypeptide (109 amino acids in humans) with diagnostic and therapeutic potential; ProTα exerts intra- and extra-cellular biological functions associated with cell proliferation, apoptosis and immune re…
Immunity is a defensive response that fights disease by identifying and destroying harmful substances or microbiological toxins. Several factors, including work-related stress, pollution, and immunosuppressive agents, contribute to low immunity and p…
Recently, we proposed a high-throughput screening workflow for the elucidation of agonistic or antagonistic growth hormone-releasing hormone (GHRH) potencies based on structural motif descriptors as a function of the starting solution. In the present…
PURPOSE: Growth hormone-releasing hormone (GHRH) is a 44-amino acid peptide that regulates growth hormone (GH) secretion. We hypothesized that a GHRH receptor (GHRH-R) antagonist, MIA-602, would inhibit bleomycin-induced lung inflammation and/or fibr…
Adrenocortical carcinomas (ACCs) are rare and highly malignant cancers associated with poor survival of patients. Currently, mitotane, a nonspecific derivative of the pesticide DDT (1,1-(dichlorobiphenyl)-2,2-dichloroethane), is used as the standard…
To effectively alleviate acute severe ulcerative colitis (ASUC), we developed a colon-specific delivery system-PLGA-KPV/MMT/CS multifunctional medicinal nanoparticles loaded with cyclosporine A (CyA). The lysine-proline-valine (KPV) tripeptide, which…
Cutaneous wound healing is a complex process divided into different phases, that is an inflammatory, proliferative and remodelling phase. During these phases, a variety of resident skin cell types but also cells of the immune system orchestrate the h…
In the past years, thecarbapenemase (KPC)-producingsequence type 258 (ST258) became an important worldwide spread nosocomial pathogen. Recent evidence shows that the global epidemiology is changing, with the rise of new lineages. In this study we rep…
The interaction of the regulatory biologically active peptide Glu-Asp-Arg (EDR) with DNA is considered by spectral, NMR, viscosimetry, and molecular dynamics methods. It was shown that EDR can partly penetrate into the major groove of DNA and affect…
Development of therapeutic preparations involves several steps, starting with the synthesis of chemical compounds and testing them in different models for selecting the most effective and safest ones to clinical trials and introduction into medical p…
An integrated methodological approach to study the molecular aspects of short regulatory neuropeptides biological mechanism is proposed. The complex research is based on radioligand-receptor method of analysis and covers such points of peptides molec…
We studied immunocorrecting effects of Semax (Met-Glu-His-Phe-Pro-Gly-Pro) on the model of "social" stress caused by sensory contact and intermale confrontation. Functional activity of the immune system of laboratory animals was evaluated in standard…
BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a substantial cause of comorbidity in people with HIV and there are no proven pharmacological treatments for the disease in this population. We assessed the effects of tesamorelin on liver fat…
BACKGROUND: Tesamorelin, a growth hormone-releasing hormone analogue, decreases visceral adipose tissue in people living with HIV, however, the effects on skeletal muscle fat and area are unknown. OBJECTIVES: The goals of this exploratory secondary a…
BACKGROUND/OBJECTIVES: Individuals with HIV are susceptible to visceral fat accumulation, which confers an increased risk of cardiometabolic disease. Advanced software to ascertain visceral fat content from dual-energy X-ray absorptiometry (DXA) has…
BACKGROUND: Responder analyses are used to determine whether changes that occur during a clinical trial are clinically meaningful; for subjective endpoints such as those based on patient-reported outcomes (PROs), responder analyses are particularly u…
