MPI values of cephalon/exoskeleton tissues were greater than those of the flesh with ranges between 11.4-24.0 and 4.6-14.3, respectively. Interestingly, the calculations of TTHQ of toddler and adult were lesser than one and not expected to pose any risk concern to human from crustaceans' consumption.The protective effect of curcumin on potassium bromate (KBrO3)-induced renal damage was investigated in vivo. Treatment with KBrO3 (20 mg/kg bw) caused a significant increase in arginase and adenosine deaminase (ADA) activities in rats' kidney. However, oral administration of curcumin (20 mg/kg bw) caused a significant reduction in ADA and arginase activities in KBrO3 + CUR group. Furthermore, nitric oxide level was significantly low in KBrO3 group compared with the control. After treatment with curcumin in KBrO3 + CUR group, nitric oxide levels increased significantly (P  less then  0.05). Determination of some kidney biomarkers revealed elevated levels of creatinine, serum urea, and electrolytes (Na+ and Cl-) in KBrO3-treated rats. Curcumin effectively reduced the levels of these renal function parameters in KBrO3 + CUR groups and were not significantly different from the control. Antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) activities as well as glutathione (GSH) levels were significantly low with concomitant higher levels of malondialdehyde (MDA) after treatment with KBrO3. Curcumin caused a significant increase in SOD, CAT, and GPX activities including GSH levels with lower production of MDA in kidney homogenates of rats in KBrO3 + CUR. Curcumin ameliorated corpuscular degeneration in the kidney tissue and exhibited protection against tubular necrosis. These results revealed the protective effect of curcumin against KBrO3-induced renal toxicity by preventing degradation of ADA and arginine, improving antioxidant status and histopathological changes in rats' kidney.This study was planned to determine the molecular basis and causes of damage to the kidney and the liver, which are the most affected tissues in sheep exposed to chronic fluoride. For this purpose, liver and kidney tissues were obtained from sheep with signs of fluorosis in the age range of 4-6 years. The control group consisted of clinically healthy sheep without fluorosis. The apoptotic and oxidative genes expression of target genes was determined using the real qRT-PCR method. According to the control gene (Gapdh) that was detected that in the liver, the apoptotic genes caspase-8, caspase-9, and Bim increased and caspase-3, Bcl-2, and Bak decreased, while in the kidney, caspase-3 and Bax and caspase-8, Bcl-2, Bcl2l-1, Bim, and Bak decreased. According to the 2-ΔCt values of the oxidative stress genes, it was determined that Cygb, Gstp1, and Ncf1 genes increased significantly in the fluorosis group and Gpx1, sod1, and sod2 genes decreased significantly. In the kidney tissue, Cygb and Gpx1 increased in the fluorosis group, while sod1, sod2, Gstp1, Ncf1 and Ccs, and Nos2 were found to decrease significantly. As a result, it was shown that apoptosis and oxidative mechanisms are activated in the liver and the kidney tissues of sheep with fluorosis and these parameters have an important role in understanding the molecular basis of tissue damage in fluorosis.STUDY OBJECTIVES Because dexmedetomidine (DEX)-induced sedation mimics non-rapid eye movement (NREM) sleep, its utility in sedating children with REM-predominant disease is unclear. We sought to determine the effectiveness of pediatric drug-induced sleep endoscopy (DISE) using DEX and ketamine for children with REM-predominant OSA, specifically whether or not at least one site of obstruction could be identified. METHODS A retrospective case series of children without tonsillar hypertrophy undergoing DISE at a tertiary pediatric hospital from 10/2013 through 9/2015 who underwent subsequent surgery to address OSA with polysomnography (PSG) before and after. RESULTS We included 56 children, mean age 5.6±5.4 years, age range 0.1-17.4 years, mean BMI 20.3±7.4 kg/m2 (76±29 percentile). At least one site of obstruction was identified in all patients, regardless of REM- or NREM-predominance. The mean obstructive apnea-hypopnea index (oAHI) improved (12.6 ± 10.7 to 9.0 ± 14.0 events/h) in children with REM-predominant (P = 0.013) and NREM-predominant disease (21.3 ± 18.9 to 10.3 ± 16.2 events/h) (P = 0.008). The proportion of children with a postoperative oAHI less then 5 was 53% and 55% for REM- and NREMpredominant OSA, respectively. Unlike children with NREM-predominant disease, children with REM-predominant disease had significant improvement in the mean saturation nadir (P less then 0.001), total sleep time (P = 0.006), and sleep efficiency (P = 0.015). CONCLUSIONS For children with OSA without tonsillar hypertrophy, DISE using DEX/ketamine was useful to predict at least one site of obstruction, even for those with REM-predominant OSA. DISE-directed outcomes resulted in significant improvements in mean oAHI, total sleep time, sleep efficiency, saturation nadir, and the proportion with oAHI less then 5, after surgery for some children with REM-predominant disease.BACKGROUND Colorectal cancer is the third most common cancer worldwide. If biomarkers can be identified in liquid biopsy, diagnosis and treatment can be optimized even when cancerous tissues are not available. The purpose of this study was to identify proteins from liquid biopsy that would be useful as markers of poor prognosis. METHODS First, we comprehensively analyzed serum proteins to identify potential biomarkers and focused on serum lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1). read more The relationship between LOX-1 and the prognosis of patients with colorectal cancer has not been reported. Next, we validated this marker using serum samples from 238 patients with colorectal cancer by ELISA and 100 tissue samples by immunohistochemical staining. RESULTS The optimal cut-off value of serum LOX-1 was 538.7 pg/mL according to time-dependent receiver operating characteristics curve analysis. The overall survival of patients with high levels of serum LOX-1 was significantly poorer than that of individuals with low levels of LOX-1 in the training and test datasets.
