This paper presents a novel thermal desorption probe integrated with the corona-discharged assisted paper-spray mass spectrometry (PS-MS) for rapid detecting the residual pesticides on fruit surfaces. Pesticide detection can be simply achieved by scratching the fruit surface and then placed in front of the inlet of the MS for target pesticides screening. A novel ionization method comprising the electrospray ionization and the corona discharged is generated on the paper tip to simultaneously ionize the pesticide of high and low polarities for MS detection.

However, the detailed mechanism of ATO in preventing gentamicin (GM)-induced renal injury remains obscure. Although underlying multifaceted mechanisms involving GM-induced nephrotoxicity were well known, further work on elucidating the essential mechanism was needed.

Huanglian and Huangbai have been used as "heat-removing" agents. In addition, berberine has been reported to exert anti-inflammatory effect both in vivo and in vitro, where mitogen-activated protein kinase (MAPK) and cyclooxygenase-2 (COX-2) expressions are critically implicated.

A total of 756 patients with symptomatic uterine myomas who underwent LM were reviewed retrospectively. A total of 225 cases of LM using LigaSure™ (LML group) were compared with a control group treated with traditional electrical cauterization (LME group) under propensity-matched analysis.

Background: To compare conventional electrosurgery, LigaSure (Valleylab, Boulder, CO), and Harmonic scalpel (Ethicon Endosurgery, Cincinnati, OH) in terms of perioperative and postoperative outcomes during laparoscopic myomectomy (LM).
Methods: We retrospectively studied 817 women with symptomatic fibroids who underwent LM between January 1997 and September 2015. Three different instruments were used separately during surgery.
Methylglyoxal (MGO) is highly cytotoxic and its levels are elevated in diabetes, nephropathy and atherosclerosis. However, it has never been studied in liver disease. For this reason, we aimed to assess the levels of MGO and its metabolite d-lactate in an early hepatitis model.

Objective: To evaluate the use of Tisseel, a 2-component fibrin sealant agent for the control of minor bleeding and repair of the ovarian defect at the end of laparoscopic cystectomy (LC) of endometriomas.
Materials And Methods: From January 2011 to December 2015, an observational study of all patients who underwent LC of endometrioma using Tisseel (group A) was performed. The demographic and operative data, including age, body mass index, operative indications, operative time, estimated blood loss, complications, and postoperative hospital stay duration were recorded.
Objective: Natural orifice transluminal endoscopic surgery (NOTES) may be useful in gynecologic endoscopic surgery. This study evaluated the efficacy, safety, and perioperative outcomes of combined NOTES and vaginal approach, transvaginal endoscopic surgery-assisted adnexectomy (TVEA), for the surgical treatment of presumed benign ovarian tumors.
Materials And Methods: Records were reviewed for 33 consecutive TVEA procedures performed between May 2011 and March 2014.

Objective: To compare the safety and effectiveness of the harmonic scalpel and conventional electrosurgery in laparoscopic myomectomy (LM).
Materials And Methods: We performed a retrospective chart review of 591 women with symptomatic uterine fibroids who underwent LM. Thirty-three cases of LMs with harmonic scalpel (LMH) were compared with a matched control group that underwent conventional electrosurgery (LME).
Lead (Pb) is an environmental pollutant associated with several diseases, such as nephrotoxicity. Methylglyoxal (MG) is a reactive dicarbonyl compound formed during glycolysis and reported to increase in kidney damage. Metformin is used as an MG scavenger in the clinic.

Early detection of disease risk, to enable intervention before advanced renal damage occurs, is an important goal. Microalbuminuria has been used to monitor renal damage in clinical settings for years.

Accumulation of MG and its downstream metabolite N (ε)-(carboxyethyl)lysine (CEL) has been identified in several variations of nephropathy, including diabetic, hypertensive, and gentamicin-induced nephropathies. In this study, we investigated the effects of low-molecular-weight chitosan (lmw-chitosan) on MG-induced carbonyl stress in aristolochic acid-induced nephropathy.

With the increase of antibiotic resistance, the use of aminoglycosides is inevitable. Low-molecular-weight chitosan (LMWC) has shown renal protective effects in dialysis patients.
View Article and Find Full Text PDFAims: Aristolochic acid (AA) nephrotoxicity is related to accumulation of methylglyoxal (MGO) and N(ε)-(carboxymethyl)lysine (CML) in the mouse kidney. We studied the activity of renal semicarbazide-sensitive amine oxidase (SSAO), a key enzyme involved in MGO generation, in AA-treated mice, and investigated nephroprotective effects produced by metformin, a MGO scavenger.
Methods: Mice were orally administered water or metformin for 15 days (12 or 24 mg kg(-1)day(-1)), and injected AA (5mgkg(-1)day(-1)) intraperitoneally for 8 days starting on day 8.
Hepatic manifestations of the metabolic syndrome are related obesity, type 2 diabetes/insulin resistance and non-alcoholic fatty liver disease. Here we investigated how the anti-inflammatory properties of lactoferrin can protect against the onset of hepatic manifestations of the metabolic syndrome by using a murine model administered with high-fructose corn syrup. Our results show that a high-fructose diet stimulates intestinal bacterial overgrowth and increases intestinal permeability, leading to the introduction of endotoxin into blood circulation and liver.

In this study, we used a C3H/3e mouse model to investigate the relationship between urinary d-lactate and aristolochic acid nephropathy where the glomerular structure is not affected. The nephropathy was induced using intravenous injections of aristolochic acid at a dosage of 10 mg/kg per day for 5 days and was characterized biochemically and histologically.
