Background Silica dioxide nanoparticles (SiONPs) have been used for various medical applications, including therapeutics and imaging, and the use of SiONPs has increased gradually over the years. However, despite an increase in the use of SiONPs, not much is known about mechanism of action of SiONPs and their pulmonary toxicity. Objective The present study investigated the pulmonary toxicity of SiONPs and explored the underlying mechanism of action, primarily focusing on thioredoxin-interacting protein (TXNIP)/NOD-like receptor pyrin domain-containing 3 (NLRP3) in SiONPs-treated mice. We investigated the toxic effects of SiONPs in the lung of BALB/c mice administered 5, 10, and 20 mg/kg SiONPs for 3 days. Results Exposure to SiONPs markedly increased inflammatory cell counts, including those of neutrophils and macrophages, and levels of inflammatory mediators, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in a dose-dependent manner in the bronchoalveolar lavage fluid. Moreover, the inflammation was verified upon histopathological analysis. In addition, exposure to SiONPs increased the expression of TXNIP in a dose-dependent manner and, in turn, upregulated NLRP3 inflammasome proteins, which subsequently induced IL-1β production. Conclusion Collectively, exposure to SiONPs induced inflammation in the lungs of mice, which resulted in the activation of IL-1β production via the TXNIP-NLRP3 axis. Our results provide useful information on the pulmonary toxicity induced by SiONPs and provide insights into the underlying mechanism of action.

Ventricular septal defect remains an infrequent but devastating complication of acute MI. Approximately 1∼3% of cases of acute myocardial infarction are complicated by ventricular septal rupture in the prethrombolytic era and the incidence has decreased to 0.2% with reperfusion therapy. This mechanical complication usually occurs within the first 10 to 14 days when necrotic tissue is most abundant and the collateral coronary circulation is not well developed. This lesion is generally associated with complete coronary obstruction rather than severe stenosis. Rupture of the ventricular septum is a severe mechanical complication of acute myocardial infarction, usually resulting in death unless surgical repair is performed. The bad prognosis of this event within the first 2 weeks indicates the need for early surgical rapair. This complication is more frequent after the first acute myocardial infarction in the elderly and secondary to a transmural myocardial infarction. We report two cases of ventricular septal rupture after acute myocardial infarction.

Moyamoya disease is an occlusive intracranial arteriopathy with an abnormal cerebral vascular collateral networks. Although this disease is known to be associated with stenosis of extracranial arteries, such as the renal artery, a case associated with stenosis of the coronary artery is extremely rare. We report a case of coronary artery occlusive disease affected by Moyamoya disease. The patient was a 38-year-old female experiencing intermittent headache and exer tional chest pain. Cerebral MRI showed complete obstruction of both internal carotid arteries and abnormal cerebrovascular systems which confirmed Moyamoya disease. Coronary angiography showed a significant stenosis of left anterior descending coronary artery ostium with TIMI grade I collateral blood flow from the normal right coronary artery. After coronary artery stenting and medical treatment for headache, her subjective symptoms were relieved. In Moyamoya patient, an evaluation of the extracranial (especially coronary artery) vascular system should be considered if there are some evidences of coronary artery disease.

Metal (loid)s such as environmental contaminants affect food safety. Metal (loid)s exist trace extremely in agriculture products. Therefore it is important to analyze accurately about trace these metals. High resolution techniques and quality controls are needed to analyze these materials. In order to achieve quality results, standardized methods and techniques are required. So ISO(International Organization for Standardization) of laboratory proficiency testing is determination of laboratory testing performance by means of inter-laboratory comparison. The values have been derived as a consensus of a number of laboratories using a variety of methods. Proficiency tests were applied to analyze the metal(loid)s [inorganic arsenic (As), total As and cadmium (Cd)] in powdered rice FAPAS 07187 (Food Analysis Performance Assessment Scheme; February-April 2013).

A soft biomolecule actuator based on a highly functionalized bacterial cellulose nano-fiber network with carboxylic acid groups

Wang, Fan,Jeon, Jin-Han,Park, Sukho,Kee, Chang-Doo,Kim, Seong-Jun,Oh, Il-Kwon The Royal Society of Chemistry 2016 SOFT MATTER Vol.12 No.1

<P>Upcoming human-related applications such as soft wearable electronics, flexible haptic systems, and active bio-medical devices will require bio-friendly actuating materials. Here, we report a soft biomolecule actuator based on carboxylated bacterial cellulose (CBC), ionic liquid (IL), and poly (3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) electrodes. Soft and biocompatible polymer-IL composites were prepared via doping of CBC with ILs. The highly conductive PEDOT: PSS layers were deposited on both sides of the CBC-IL membranes by a dip-coating technique to yield a sandwiched actuator system. Ionic conductivity and ionic exchange capacity of the CBC membrane can be increased up to 22.8 times and 1.5 times compared with pristine bacterial cellulose (BC), respectively, resulting in 8 times large bending deformation than the pure BC actuators with metallic electrodes in an open air environment. The developed CBC-IL actuators show significant progress in the development of biocompatible and soft actuating materials with quick response, low operating voltage and comparatively large bending deformation.</P>

Cisplatin에 의한 마우스의 급성 신부전 완화에 대한 Endothelin A 수용체의 차단 효과

김일두,안도환 고신대학교의과대학 2007 고신대학교 의과대학 학술지 Vol.22 No.1

Background : Acute renal failure (ARF) can be pathophysiologically classified to hemodynamically-mediated or nephrotoxic type, and in either case, endothelin (ET)-1 expression is enhanced in renal tissues. Hemodynamically-mediated ARF is known to be mitigated by ETA receptor (ETAR) blocker but not ETB receptor (ETBR) blocker. There is poorly understood on mitigation of renal injuries by ETAR or ETBR blockade in nephrotoxic ARF. Therefore, This study examined whether nephrotoxic ARF induced by cisplatin is functionally and/or histologically ameliorated by ETAR blocker BQ123. Materials and Methods : Male C57BL/6 mice are intraperitoneally injected with vehicle (saline), cisplatin or cisplatin+BQ123. Cisplatin was single administrated with a dose of 16 mg/kg/day and BQ123 with a dose of 24 mg/kg/day once a day for 4 consecutive days including a baseline day. Urine flow, excretion of electrolytes and protein, and creatinine clearance were measured. Histological changes were observed through periodic acid-Schiff stain. Real time RT-PCR was performed to evaluate expression of ET-1 and ETAR mRNA. Distribution of ET-1 peptide within renal cortex was examined by immunohistochemistry. Results : Body weight, urine flow, excretion of protein, Na, K, and creatinine clearance tended to decrease by cisplatin administration compared to vehicle treatment, but these parameters did not return to the normal level by combined administration of cisplatin and BQ123. Necroses of several proximal tubules were observed in the cisplatin group, indicating that mild nephrotoxicity occured. In the cisplatin+BQ123 group, this change seemed to increase, rather than decrease. Expression of ET-1 and ETAR mRNA was 6 and 2-fold higher in the cisplatin group than the saline group, respectively. BQ123 treatment reversed ETAR mRNA expression to the basal level but not ET-1 mRNA. Immnuoreactive ET-1 was mainly distributed within proximal tubule cells in all three groups. Immunoreactivity of ET-1 was enhanced in both the cisplatin group and the cisplatin+BQ123 group compared to the saline group, but was similar between the cisplatin group and the cisplatin+BQ123 group. Conclusion : Administration of a ETAR blocker BQ123 in cisplatin-induced nephrotoxic ARF is not likely to be effective in amelioration of renal injuries.
