Given in reperfusion, the use of stable gastric pentadecapeptide BPC 157 is an effective therapy in rats. It strongly counteracted, as a whole, decompression/reperfusion-induced occlusion/occlusion-like syndrome following the worst circumstances of a…
INTRODUCTION: GHK-Cu and HA are two commonly used skin care ingredients, both of which were reported to enhance collagen synthesis. This work aims to investigate their co-effect on collagen regulation. MATERIALS AND METHODS: In cell experiments, huma…
Sleep deprivation is known to cause memory impairment and is associated with inflammation and cell damage linked to neurodegenerative diseases. GHK (glycyl-L-histidyl-L-lysine) is a naturally occurring tripeptide found in mammalian plasma. GHK has an…
BACKGROUND: Skeletal muscle dysfunction is an important co-morbidity in patients with chronic obstructive pulmonary disease (COPD) and is significantly associated with increased mortality. Oxidative stress has been demonstrated an important trigger f…
Hydrogen sulfide (HS) has emerged as an endogenous signaling molecule that functions in many physiological and pathological processes of human cells in health and disease, including neuromodulation and neuroprotection, inflammation, angiogenesis, and…
Efforts to find disease modifying treatments for Alzheimer's disease (AD) have met with limited success in part because the focus has been on testing drugs that target a specific pathogenic mechanism. Multiple pathways have been implicated in the pat…
Brain aging and cognitive decline are aspects of growing old. Age-related cognitive impairment entails the early stages of cognitive decline, and is extremely common, affecting millions of older people. Investigation into early cognitive decline as a…
Liposomes are self-assembled spherical systems composed of amphiphilic phospholipids. They can be used as carriers of both hydrophobic and hydrophilic substances, such as the anti-aging and wound-healing copper-binding peptide, GHK-Cu (glycyl-L-histi…
The aim of this study is the synthesis of novel peptide-silver nanoparticle conjugates with enhanced wound healing capacity. Peptide-silver nanoparticle conjugates were synthesized using myristoyl tetrapeptide 6 (MT6) or copper tripeptide 1 (CuTP1).…
Sensing important metals in different environments is an important area and involves the development of a wide variety of metal-sensing materials. The employment of fluorescent sensors in metal sensing has been one of the most widely applied methodol…
Artificial solid-state nanochannels have garnered considerable attention as promising nanofluidic tools for ion/molecular detection, DNA sequencing, and biomimicry. Recently, nanofluidic devices have emerged as cost-effective detection tools for heav…
The Fiber SPR chip laboratory has become a popular choice in biochemical detection. To meet the needs of different kinds of analytes for the detection range and number of channels of the chip, we proposed a multi-mode SPR chip laboratory based on mic…
Fixed airflow limitation (FAO), prevalent in patients with severe or difficult-to-treat asthma, is mainly caused by airway remodeling. Airway remodeling is initiated by inflammation and involves subsequent pathological changes. Glycyl-l-histidyl-l-ly…
A highly efficient strategy using Copper-Glycyl-L-Histidyl-L-Lysine (GHK-Cu) as a novel inducer was developed to enhance laccase production by. After medium optimization, laccase activity increased by 12.77-fold compared to that without GHK-Cu. The l…
Metal chelators are used for various industrial and medical purposes based on their physicochemical properties and biological activities. In biological systems, copper ions bind to certain enzymes as cofactors to confer catalytic activity or bind to…
INTRODUCTION: Despite the promising results of intralesional vitamin D in verruca treatment; its precise mechanism of action is not fully understood. AIM OF THE WORK: To investigate immunohistochemical expression of cathelicidin (LL 37) before and af…
OBJECTIVE: This study aimed to evaluate the efficacy of narrow-band ultraviolet B (NB-UVB) phototherapy, methotrexate, and combined NB-UVB phototherapy with methotrexate in the treatment of psoriasis vulgaris and to assess their effects on serum cath…
The intracellular Caconcentration is mainly controlled by Cachannels. These channels form complexes with Kchannels, which function to amplify Caflux. In cancer cells, voltage-gated/voltage-dependent Cachannels and non-voltage-gated/voltage-independen…
BACKGROUND: Crotalicidin (Ctn), a snake venom cathelicidin-related antimicrobial peptide, is a 34-residue-long linear lysine-rich vipericidin obtained from the South American rattlesnake, Crotalus durissus terrificus. Ctn contains tandem repeats of n…
Rosacea is a chronic inflammatory disease characterized by facial flushing, erythema, telangiectasia, papules, and pustules. Its pathogenesis has not been fully understood. In 2017, the global ROSacea COnsensus (ROSCO) panel updated the diagnosis, cl…
