Background: The neutrophil-to-lymphocyte ratio (NLR) is a strong predictor of mortality in patients with colorectal, lung, gastric cancer, pancreatic and metastatic renal cell carcinoma. We here evaluated whether preoperative NLR is an independent prognostic factor for non-metastatic renal cell carcinoma (RCC). Materials and Methods: Data from 327 patients who underwent curative or palliative nephrectomy were evaluated retrospectively. In preoperative blood routine examination, neutrophils and lymphocytes were obtained. The predictive value of NLR for non-metastatic RCC was analyzed. Results: The NLR of 327 patients was $2.72{\pm}2.25$. NLR <1.7 and NLR ${\geq}1.7$ were classified as low and high NLR groups, respectively. Chi-square test showed that the preoperative NLR was significantly correlated with the tumor size (P=0.025), but not with the histological subtype (P=0.095)and the pT stage (P=0.283). Overall survival (OS) and disease-free survival (DFS) were assessed using the Kaplan-Meier method. Effects of NLR on OS (P=0.007) and DFS (P=0.011) were significant. To evaluate the independent prognostic significance of NLR, multivariate COX regression models were applied and identified increased NLR as an independent prognostic factor for OS (P=0.015), and DFS (P=0.019). Conclusions: Regarding patient survival, an increased NLR represented an independent risk factor, which might reflect a higher risk for severe cardiovascular and other comorbidities. An elevated blood NLR may be a biomarker of poor OS and DFS in patients with non-metastatic RCC.

BACKGROUND/OBJECTIVES: Docosahexaenoic acid (DHA), an n-3 long chain polyunsaturated fatty acid (LCPUFA), is acquired by dietary intake or the in vivo conversion of ${\alpha}$-linolenic acid. Many enzymes participating in LCPUFA synthesis are regulated by peroxisome proliferator-activated receptor alpha ($PPAR{\alpha}$). Therefore, it was hypothesized that the tissue accretion of endogenously synthesized DHA could be modified by $PPAR{\alpha}$. MATERIALS/METHODS: The tissue DHA concentrations and mRNA levels of genes participating in DHA biosynthesis were compared among $PPAR{\alpha}$ homozygous (KO), heterozygous (HZ), and wild type (WT) mice (Exp I), and between WT mice treated with clofibrate ($PPAR{\alpha}$ agonist) or those not treated (Exp II). In ExpII, the expression levels of the proteins associated with DHA function in the brain cortex and retina were also measured. An n3-PUFA depleted/replenished regimen was applied to mitigate the confounding effects of maternal DHA. RESULTS: $PPAR{\alpha}$ ablation reduced the hepatic Acox, Fads1, and Fads2 mRNA levels, as well as the DHA concentration in the liver, but not in the brain cortex. In contrast, $PPAR{\alpha}$ activation increased hepatic Acox, Fads1, Fads2, and Elovl5 mRNA levels, but reduced the DHA concentrations in the liver, retina, and phospholipid of brain cortex, and decreased mRNA and protein levels of the brain-derived neurotrophic factor in brain cortex. CONCLUSIONS: LCPUFA enzyme expression was altered by $PPAR{\alpha}$. Either $PPAR{\alpha}$ deficiency or activation-decreased tissue DHA concentration is a stimulus for further studies to determine the functional significance.

Waterlogging is one of the major environmental challenges that can adversely impact squash growth, development, and productivity. Nevertheless, studies on the physiological changes of squash to waterlogging stress are scarce. Previously, we reported that the Cucurbita moschata (Cmo) Early Price (Ep) cultivar showed higher chlorophyll content (CC) and spectral refl ectance compared to the Cucurbita maxima (Cma) OK-101 (Ok) cultivar after waterlogging. In the present work, we further examined more physiological parameters in eight cultivars of Cmo and Cma, and studied whether these non-destruc tive indices could effi ciently identify various waterlogging-tolerant genotypes and were consistent with visual evaluations. Moreover, we investigated the eff ects of waterlogging on the antioxidant system of cucurbit species, and evaluated dynamic changes occurring in these plants during varying waterlog periods by determining physiological characteristics. The activ ity of ascorbate peroxidase (APX) and superoxide dismutase (SOD) showed a signifi cant increase in Ep plant leaves and roots after 72 h and 6 h of waterlogging, respectively, compared to Ok plants. In addition, Ep exhibited a higher tolerance to waterlogging than Ok in terms of enhanced root length, values in CC, spectral refl ectance, and APX and SOD activity, plus decreased levels of electrolyte leakage, 2,2-diphenyl-1-picrylhydrazyl free radical scavenging, and hydrogen peroxide levels. This study provides a comprehensive understanding of the physiological variations in response to waterlogging stress and can potentially be used to breed cucurbit species with waterlogging tolerance for a wetter future climate.
