REVIEW
Cheal Wung Huh, Byung Wook Kim
Gastric adenoma (dysplasia) is a precancerous lesion. Therefore, managements of gastric adenomas are important for preventing the development of gastric cancers and for detecting gastric cancers at earlier stages. The Vienna classification divides gastric adenomas into two categories: high-grade dysplasia and low-grade dysplasia. Generally, endoscopic resection is performed for adenoma with high-grade dysplasia due to the coexistence of carcinoma and the potential of progression to carcinomas. However, the treatments of adenoma with low-grade dysplasia remain controversial...

The potential applications of low temperature plasma (LTP) in wound healing have aroused the concern of many researchers. In this study, an argon atmospheric pressure plasma jet was applied to generate LTP for treatment of murine fibroblast cell (L929) cultured in vitro to investigate the effect of NF-κB pathway on fibroblast proliferation. The results showed that, compared with the control, L929 cells treated with plasma for less than 20 s had significant increases of proliferation; the productions of intracellular ROS, O2(-) and NO increased with prolongation of LTP treatment time; NF-κB pathway was activated by LTP in a proper dose range, and the expression of cyclinD1 in LTP-treated cells increased with the same trend as cell proliferation...

OBJECTIVES: Symptomatic cervical heterotopic gastric mucosa also addressed as cervical inlet patch (CIP) may present in varying shapes and causes symptoms of laryngopharyngeal reflux (LPR) like globus sensations, hoarseness and chronic cough. Unfortunately, argon plasma coagulation, standard treatment of small symptomatic CIP, is limited in large CIP mainly due to concerns of stricture formation. Therefore, we aimed to investigate radiofrequency ablation (RFA), a novel minimal-invasive ablation method, in the treatment of CIP focusing on large symptomatic patches...

Patients with Barrett's esophagus (BE)/columnar lined esophagus (CLE) and adenocarcinoma are increasing, in whom 0.61% BE/CLE would develop to adenocarcinoma. The prognosis of esophageal cancer is related to the tumor stage at diagnosis. To standardize the screening, diagnosis and therapy of BE and adenocarcinoma in China, 31 digestive diseases and digestive endoscopy experts and digestive histologists drafted the consensus on the basis of clinical experience and references. The consensus defined BE as a complication of gastroesophageal reflux disease...

A novel method for preparing durable superamphiphobic fabrics is reported, which involves preapplying a solution consisting of perfluoroalkyl acrylate, epoxide-containing silane, and silica nanoparticles onto fabric and subsequent argon-plasma treatment. The coated fabrics show superphobic to both water and oil fluids (surface tension >21.5 mN m(-1) ). The coating is durable to withstand repeated laundries and multicycles of abrasion without apparently altering the superamphiphobicity. The coating is also very stable in boiling water, strong acid, and base, but has little effect on the fabric handle and air permeability...

The current standard-of-care treatment for patients with limited-stage small-cell lung cancer (SCLC) is concurrent chemoradiotherapy for local and systemic control. However, standard-of-care treatment strategies have not been established for those with limited-stage SCLC who have a history of thoracic radiotherapy due to concerns with complications associated with radiation overdose. A 37-year-old male developed an aspergilloma in the postoperative left thoracic space after he was treated with concurrent chemoradiotherapy for mediastinal type lung adenocarcionoma and subsequent left upper lobectomy for heterochronous dual adenocarcinoma...

REVIEW
Deepanshu Jain, Naemat Sandhu, Shashideep Singhal
Benign anastomotic strictures can occur in up to 22% of patients who undergo colonic or rectal resection. Traditionally, surgery was the preferred method of treatment, but, over time, endoscopic techniques, such as balloon dilation, have become the preferred modality. However, a high stricture recurrence rate of up to 18-20% and the increased risk of perforation due to uncontrolled stretching are its major drawbacks. Endoscopic electrocautery incision (EECI) allows for controlled mucosal incision in predetermined locations of stricture...

Metacomposites, composite materials exhibiting negative permittivity, represent an opportunity to create materials with depressed plasmon frequency without the need to create complex structural geometries. Although many reports exist on the synthesis and characterizations of metacomposites, very few have ventured into exploring possible applications that could take advantage of the unique electrical properties of these materials. In this article, we report on the chemiresistive properties of a polymer-CNT metacomposite and explore how these are affected by Argon plasma treatment...

Danhua Mei, Xin Tu
Direct conversion of CO2 into CO and O2 was carried out in a packed-bed dielectric barrier discharge (DBD) non-thermal plasma reactor at low temperatures and atmospheric pressure. The maximum CO2 conversion of 22.6% was achieved when BaTiO3 pellets were fully packed into the discharge gap. The introduction of γ-Al2O3 or 10 wt.% Ni/γ-Al2O3 into the BaTiO3 packed DBD reactor increased both CO2 conversion and energy efficiency of the plasma process. Packing γ-Al2O3 or 10 wt.% Ni/γ-Al2O3 in the upstream of the BaTiO3 bed showed higher CO2 conversion and energy efficiency compared to that using middle or downstream packing modes as the reverse reaction of CO2 conversion - the recombination of CO and O to form CO2 is more likely to happen in the middle and downstream modes...

Fibroepithelial polyps are benign lesions, frequently found in the skin and genitourinary tract. Airway involvement is rare, and few case reports have been published. Our patient was a 79 y.o. male smoker, who was referred to us with a 3-month history of dry cough. At physical examination, the patient looked well, but a chest CT showed a 6-mm polyp lesion in his trachea. A flexible bronchoscopy confirmed this lesion, and forceps biopsies were performed. Argon plasma coagulation was used to completely resect and treat the lesion...

Endophthalmitis, an inflammation of the eye due to perioperative infection, may occur after cataract surgery. Intraocular lenses (IOLs) loaded with an antibiotic have been proposed as an alternative to the conventional postoperative endophthalmitis prophylaxis, since the antibiotic is delivered directly to the target site. In this work, an IOL-based antibiotic releasing system was prepared from a copolymer used in the production of IOLs and a fluoroquinolone used in endophthalmitis prophylaxis (moxifloxacin, MFX)...

Non-thermal plasma has been used in many medical applications, including treatment of living cells, blood coagulation, wound healing, and sterilization. The process uses an environmentally friendly gas (e.g., argon, helium, oxygen, nitrogen, or hydrogen) to destroy bacteria cells with no serious adverse effect on humans or animals. However, information on the effect of argon plasma on blow fly eggs is lacking. In this study, we explored the ability of cold argon plasma to destroy the eggs of the Australian sheep blow fly, Lucilia cuprina (Wiedemann, 1830); its larvae are a myiasis-producing agent in both human and animals...

Low temperature (cold) plasma finds an increasing number of applications in biology, medicine and agriculture. In this paper, we report a new effect of plasma induced morphing and movements of Venus flytrap and Mimosa pudica. We have experimentally observed plasma activation of sensitive plant movements and morphing structures in these plants similar to stimulation of their mechanosensors in vivo. Application of an atmospheric pressure argon plasma jet to the inside or outside of a lobe, midrib, or cilia in Dionaea muscipula Ellis induces trap closing...
