Background: Nasopharyngeal carcinoma (NPC) is especially prevalent in southeast Asia and southern China, but its molecular mechanisms remain poorly characterized. DNA methylation is associated with initiation and progression of tumors, including NPC. Through a genome-wide DNA methylation screening approach, we discovered ZNF154, but its methylation status and roles in NPC have not been investigated. Methods: The methylation status of ZNF154 in NPC was detected with Methylation specific-PCR (MSP) and Quantitative Sequenom MassARRAY...

Amnion and amniotic tissue has been studied for more than 100 years in the treatment of acute and chronic wounds. Recent studies have focused on the use of amnion tissue in the management of full-thickness diabetic wounds, particularly of the lower extremities. With new harvesting, processing, and distribution technologies, amnion is increasingly available in treating these wounds. Current data and research show increased healing potential and decreased healing times, pain, drainage, and infection in wounds treated with amnion products...

BACKGROUND AND AIMS: Hyperbaric oxygen (HBO) therapy is increasingly used in medical practice as a means of enhancing the formation of collagen matrix and angiogenesis, thus promoting healing in wounds and necrotic tissue. However, there are concerns that oxygen can also associate with increased production of oxygen free radicals and oxidative stress. F2-Isoprostanes (F2-IsoPs) formed by non-enzymatic oxidation of arachidonic acid (AA) are reliable measures for assessing oxidative stress in vivo...

The selection of topical and systemic therapies for the treatment of venous ulcers with signs of infection is challenging and should be accompanied by specific precautionary measures to protect against cross-contamination in the presence of multidrug-resistant microorganisms. However, there are still no clinical indicators for this situation, and confirmation of resistant strains occurs through culture and sensitivity, which can take up to 14 days. During this period, protective measures may no longer be taken, contributing to the spread of these pathogens...

Hepatocellular carcinoma (HCC) is one of the major causes of cancer‑related mortality, and the prognosis of HCC patients is unsatisfactory. It is known that the occurrence and development of HCC involves numerous genes, as well as various steps and stages in the pathological process. High mobility group AT‑hook 1 (HMGA1) and integrin‑linked kinase (ILK) may be overexpressed in HCC and may serve important roles in the development of cancer; however, the relationship between HMGA1 and ILK in HCC has not been examined...

Skin wounds are continuously exposed to bacteria and can easily become infected. Infected wounds require antibiotic treatment, and infections caused by drug-resistant bacteria are an important public health problem. Antimicrobial peptides have broad-spectrum antibacterial activity, induce little or no drug resistance and may be suitable for treating skin infections caused by drug-resistant bacteria. We previously reported the design and function of myxinidin and myxinidin analogues. Here we showed that myxinidin2 and myxinidin3 exhibit antimicrobial and anti-biofilm activities against antibiotic-resistant Staphylococcus aureus, Acinetobacter baumannii, and Pseudomonas aeruginosa in high salt environments and in gelatin...
