The role of hypothalamic growth hormone-releasing hormone (GHRH) in the release of growth hormone (GH) from the pituitary is well established. However, direct effects of GHRH and its agonistic analogs on extra-pituitary cells and tissues have not bee…
PURPOSE: The aim of the study was to investigate the signaling of growth hormone-releasing hormone receptor (GHRH-R) in the pathogenesis of pterygium and determine the apoptotic effect of GHRH-R antagonist on pterygium epithelial cells (PECs). METHOD…
The effects of the growth hormone-releasing hormone (GHRH) agonist MR409 on various human cancer cells were investigated. In H446 small cell lung cancer (SCLC) and HCC827 and H460 (non-SCLC) cells, MR409 promoted cell viability, reduced cell apoptosi…
The synthesis of analogues of hypothalamic neuropeptide growth hormone-releasing hormone (GHRH) is an efficient strategy for designing new therapeutic agents. Several promising synthetic agonist and antagonist analogues of GHRH have been developed ba…
Peptides that exhibit enzymatic or hormonal activities are regulatory factors and desirable therapeutic drugs because of their high target specificity and minimal side effects. Unfortunately, these drugs are susceptible to enzymatic degradation, lead…
The use of systematic approach for the analysis of mechanism of action of drugs at different levels of biological organization of organisms is an important task in experimental and clinical pharmacology for drug designing and increasing the efficacy…
The effects of nootropic drug Semax on the neuronal network of the brain were studied by the resting state functional magnetic-resonance imaging (resting state fMRI). The study was carried out on two groups of healthy volunteers (11 men and 13 women…
AIM: To evaluate the efficacy of semax and timing of rehabilitation on the dynamics of plasma BDNF levels, motor performance, and Barthel index score in patients after ischemic stroke (IS). MATERIAL AND METHODS: One hundred and ten patients after IS…
The concentration-clamp experiments with neurons isolated from the rat brain showed that nootropic and neuroprotective drug Semax added to perfusion solution at concentration of 1 μM augmented the amplitude of GABA-activated ionic currents in cerebel…
Female sexual dysfunction (FSD) is a highly prevalent, yet commonly underdiagnosed and undertreated condition. This paper reviews the diagnostic terminology for FSD, and basic sexual physiology in women. The Food and Drug Administration (FDA) approve…
OBJECTIVE: To quantify the placebo effect of various pharmacologic modalities including neuromodulators, hormonal agents, and onabotulinum toxin A for female sexual dysfunction. DATA SOURCES: Using Meta-analyses Of Observational Studies in Epidemiolo…
BACKGROUND: Regarding hypoactive sexual desire disorder (HSDD) in women, some reviewers judge the effect size small for medications vs placebo, but substantial for cognitive behavior therapy (CBT) or mindfulness meditation training (MMT) vs wait list…
INTRODUCTION: Hypoactive sexual desire disorder (HSDD) often has a negative impact on the health and quality of life of women; however, many women do not mention-let alone discuss-this issue with their physicians. Providers of gynecologic services ha…
BACKGROUND: Thymosin beta 4 (Tβ4) is a 43-amino-acid peptide with protective properties in myocardium injury. Previously, we produced a recombinant human dimeric Tβ4 (DTβ4). Here, the cardioprotective effects of DTβ4 and the molecular mechanisms unde…
The molecular mechanisms underlying the pathogenesis of diffuse-type gastric cancer (DGC) have not been adequately explored due to a scarcity of appropriate animal models. A recently developed tool well suited for this line of investigation is the Pd…
INTRODUCTION: Sepsis is the dysregulated host response to an infection resulting in life-threatening organ damage. Thymosin Beta 4 is an actin binding protein that inhibits the polymerization of G-actin into F-actin and improves mortality when admini…
INTRODUCTION: Thymosin beta-4 (TB4) is an endogenous peptide with protective and regenerative effects in models of cellular and organ injury. TB4 is increasingly measured as a potential plasma or serum biomarker in human cardiovascular, liver, infect…
OBJECTIVE: We wanted to determine the impact of different doses of a pegylated and liposomal formulation of the cardiotoxic drug doxorubicin on cardiac function, fibrosis and survival in mice. The drug causes myocardial damage by producing reactive o…
Thymosin β4 (Tβ4) is known to inhibit an inflammatory response and to increase the survival of osteoblasts on titanium (Ti) surfaces. Ti is the most widely used graft material in dentistry; however, an inflammatory response induced following implant…
Although enhanced thymosin β4 (TMSB4X/Tβ4) expression is associated with tumor progression and metastasis, its tumor-promoting functions remain largely unknown. Here, it is demonstrated that TGFβ facilitates Tβ4 expression and leads to the activation…
