Aim: To compare the efficacy and safety of paclitaxel liposome (Lipusu$^{(R)}$) with paclitaxel in combination with tegafur and oxaliplatin in treating patients with advanced gastric cancer. Materials and Methods: Patients with advanced gastric cancer receiving chemotherapy were retrospectively collected, and divided into two groups. Patients in group A received paclitaxel liposomes at a dose of 135 $mg/m^2$ on day 1 of each cycle, and patients in group B were given paclitaxel at the same dose with the same timing. All patients received tegafur at a dose of 500 $mg/m^2$ on days 1-5, and oxaliplatin at a dose of 80-100 $mg/m^2$ on day 1 for 2 cycles (each cycle was 21 d in total). Results: Fifty-eight patients could be evaluated for efficacy. The overall response rate was 47% in group A (14/30), and 46% in group B (13/28). Disease control rate was 73% in group A (22/30), and 71% in group B (20/28) (P>0.05). No significant differences were detected in hematologic and neurologic toxicities between the two groups (P>0.05). However, nausea, vomiting and hypersensitive reactions were significantly lower in group A than in group B (P<0.05). Conclusion: Paclitaxel liposomes are as effective as paclitaxel when combined with tegafur and oxaliplation in treating patients with advanced gastric cancer, but adverse reactions with paclitaxel liposomes are less common.

Nuclear receptors (NRs), which belong to a superfamily of ligand-dependent transcription factors, play essential roles in gene regulation to affect numerous physiological pathways. Twenty NR genes were identified in Nilaparvata lugens by using genomic, transcriptomic and GenBank databases, and categorized into NR0-NR6 subfamilies according to standard nomenclature. Among them, three NR geneswere classed into NR0, four into NR1, eight into NR2, one into NR3, one into NR4, two into NR5, and one into NR6, respectively. A phylogenetic tree of NRs from N. lugens and other representative species was constructed, which provided evolutionary insight into genetic distance. In order to investigate the NRs,whichwere induced by sulfoxaflor, time- and tissue-specific expression profiles of NR genes in fourth-instar nymphs were determined following LD50 sulfoxaflor treatment (0.28 ng/insect) and compared with control samples. NlUSP, NlE78, NlTLL, NlHR51, NlHR83, NlPNR and NlFTZ-F1 were highly expressed following 12–48 h of sulfoxaflor treatment. NlHR39 and NlDSF transcripts were detected in the head and the thorax, respectively. High-level and constitutive expression of NlHR3, NlTLL, NlHR83, NlFTZF1 and NlHR4 were found in the abdomen. Feeding of dsRNAs reduced the expression of NlHR3, NlUSP, NlTLL, NlHR83, NlPNR, NlFTZ-F1 and NlHR4 (35.48–49.77%) and caused significant nymph mortality (69.21–81.45%). These NRs, considered as insecticide targets, may play important function in sulfoxaflor detoxification.

Background: Maternal Toxoplasma gondii (T. gondii) infection during pregnancy has been associated with various mental illnesses in the offspring. Ginsenoside Rh2 (GRh2) is a major bioactive compound obtained from ginseng that has an anti-T. gondii effect and attenuates microglial activation through toll-like receptor 4 (TLR4)/nuclear factor-kappa B (NF-kB) signaling pathway. GRh2 also alleviated tumor-associated or lipopolysaccharide-induced depression. However, the effects and potential mechanisms of GRh2 on depression-like behavior in mouse offspring caused by maternal T. gondii infection during pregnancy have not been investigated. Methods: We examined GRh2 effects on the depression-like behavior in mouse offspring, caused by maternal T. gondii infection during pregnancy, by measuring depression-like behaviors and assaying parameters at the neuronal and molecular level. Results: We showed that GRh2 significantly improved behavioral measures: sucrose consumption, forced swim time and tail suspended immobility time of their offspring. These corresponded with increased tissue concentrations of 5-hydroxytryptamine and dopamine, and attenuated indoleamine 2,3-dioxygenase or enhanced tyrosine hydroxylase expression in the prefrontal cortex. GRh2 ameliorated neuronal damage in the prefrontal cortex. Molecular docking results revealed that GRh2 binds strongly to both TLR4 and high mobility group box 1 (HMGB1). Conclusion: This study demonstrated that GRh2 ameliorated the depression-like behavior in mouse offspring of maternal T. gondii infection during pregnancy by attenuating the excessive activation of microglia and neuroinflammation through the HMGB1/TLR4/NF-kB signaling pathway. It suggests that GRh2 could be considered a potential therapy in preventing and treating psychiatric disorders in the offspring mice of mothers with prenatal exposure to T. gondii infection.

Background: Ginsenoside Rh2 (GRh2) is a characterized component in red ginseng widely used in Korea and China. GRh2 exhibits a wide range of pharmacological activities, such as anti-inflammatory, antioxidant, and anticancer properties. However, its effects on Toxoplasma gondii (T. gondii) infection have not been clarified yet. Methods: The effect of GRh2 against T. gondii was assessed under in vitro and in vivo experiments. The BV2 cells were infected with tachyzoites of T. gondii RH strain, and the effects of GRh2 were evaluated by MTT assay, morphological observations, immunofluorescence staining, a trypan blue exclusion assay, reverse transcription PCR, and Western blot analyses. The in vivo experiment was conducted with BALB/c mice inoculated with lethal amounts of tachyzoites with or without GRh2 treatment. Results and conclusion: The GRh2 treatment significantly inhibited the proliferation of T. gondii under in vitro and in vivo studies. Furthermore, GRh2 blocked the activation of microglia and specifically decreased the release of inflammatory mediators in response to T. gondii infection through TLR4/NF-kB signaling pathway. In mice, GRh2 conferred modest protection from a lethal dose of T. gondii. After the treatment, the proliferation of tachyzoites in the peritoneal cavity of infected mice markedly decreased. Moreover, GRh2 also significantly decreased the T. gondii burden in mouse brain tissues. These findings indicate that GRh2 exhibits an antieT. gondii effect and inhibits the microglial activation through TLR4/NF-kB signaling pathway, providing the basic pharmacological basis for the development of new drugs to treat toxoplasmic encephalitis.

Functional Components and Antioxidant Effects of Colored Onions
Xiao Nan Yang,Enning Xu,Mi Jin Park,In Jong Ha,Jin Seong Moon,Young-Hwa Kang 경북대학교 농업생명과학대학 2015 Current Research on Agriculture and Life Sciences Vol.33 No.2
The antioxidant capacities, total phenolic contents (TPC), and total quercetin contents (TQC) of a red (Chenjujuck), a yellow (Sunpower), and a white (Grasier) onion cultivar were determined in this study. Onion was separated into edible portion and dry skin. In the case of edible portion, the yellow onion had the highest antioxidant activity, followed by the red onion. The white onion showed neither antioxidant activity nor quercetin compounds. On the other hand, the dry skin of the red onion showed higher antioxidant activity than yellow onion skin. The white onion skin had slight antioxidant activity, low TPC, and no quercetin compounds. In addition, the flavonoid compounds of the edible portion and dry skins of these colored onions were analyzed by UFLC(ultra-fast liquid chromatography). The major compounds were quercetin 3,4-diglucoside and quercetin 4- glucoside in yellow and red onion edible portion, whereas the major compounds in yellow and red onion skins were quercetin 4- glucoside, quercetin, and quercetin 3,4-diglucoside.

<P><B>Abstract</B></P> <P>Trophic-functional groupings are an important biological trait to summarize community structure in functional space. The heterogeneity of the tropic-functional pattern of protozoan communities and its environmental drivers were studied in coastal waters of the Yellow Sea during a 1-year cycle. Samples were collected using the glass slide method at four stations within a water pollution gradient. A second-stage matrix-based analysis was used to summarize spatial variation in the annual pattern of the functional structure. A clustering analysis revealed significant variability in the trophic-functional pattern among the four stations during the 1-year cycle. The heterogeneity in the trophic-functional pattern of the communities was significantly related to changes in environmental variables, particularly ammonium-nitrogen and nitrates, alone or in combination with dissolved oxygen. These results suggest that the heterogeneity in annual patterns of protozoan trophic-functional structure may reflect water quality status in coastal ecosystems.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The annual patterns of functional structure of protozoa showed clear spatial variations. </LI> <LI> Spatial variations in functional structure were significantly related to nutrient variables. </LI> <LI> Nutrients and dissolve oxygen may be the main drivers to shape the spatial differences. </LI> <LI> Spatial pattern of functional structure of protozoa may reflect water quality status. </LI> </UL> </P>

The Immunomodulation Effect of Aronia Extract Lacks Association with Its Antioxidant Anthocyanins
Jin Xu,Biljana Mojsoska 한국식품영양과학회 2013 Journal of medicinal food Vol.16 No.4
Polyphenols comprise a diverse group of molecules with antioxidative and anti-inflammatory activities. To compare the antioxidative and anti-inflammatory capacity of Aronia melanocarpa berries (chokeberries), recognized for their high content of anthocyanins, a noncytotoxic isolation method was developed to obtain high-purity anthocyanins in the extract. The antioxidative activity of the extract, the anthocyanin-rich fraction (AF) was determined by 1,1-diphenyl-2-picrylhydrazyl radical and ferric-reducing ability of plasma along with resveratrol as a reference. The immunomodulation properties were assessed in lipopolysaccharide (LPS)-stimulated human monocytes mono mac 6. The isolated AF, containing six different anthocyanins, exhibited a stronger antioxidative capacity compared to resveratrol. Resveratrol enhanced tumor necrosis factor-α and reduced interleukin-10 (IL-10) production by LPS, whereas AF only had a slight effect in reducing IL-10. These results demonstrated that there was no major relationship between the antioxidative effect and immunomodulation capacities of AF and resveratrol. The immunomodulatory activity of the extract is associated with bioactive compounds in Aronia other than its anthocyanins.

High dietary inorganic phosphate increases lung tumorigenesis and alters Akt signaling.
Jin, Hua,Xu, Cheng-Xiong,Lim, Hwang-Tae,Park, Sung-Jin,Shin, Ji-Young,Chung, Youn-Sun,Park, Se-Chang,Chang, Seung-Hee,Youn, Hee-Jeong,Lee, Kee-Ho,Lee, Yeon-Sook,Ha, Yoon-Cheol,Chae, Chan-Hee,Beck, Geo American Lung Association 2009 American journal of respiratory and critical care Vol.179 No.1
<P>RATIONALE: Phosphate (Pi) is an essential nutrient to living organisms. Recent surveys indicate that the intake of Pi has increased steadily. Our previous studies have indicated that elevated Pi activates the Akt signaling pathway. An increased knowledge of the response of lung cancer tissue to high dietary Pi may provide an important link between diet and lung tumorigenesis. OBJECTIVES: The current study was performed to elucidate the potential effects of high dietary Pi on lung cancer development. METHODS: Experiments were performed on 5-week-old male K-ras(LA1) lung cancer model mice and 6-week-old male urethane-induced lung cancer model mice. Mice were fed a diet containing 0.5% Pi (normal Pi) and 1.0% Pi (high Pi) for 4 weeks. At the end of the experiment, all mice were killed. Lung cancer development was evaluated by diverse methods. MEASUREMENT AND MAIN RESULTS: A diet high in Pi increased lung tumor progression and growth compared with normal diet. High dietary Pi increased the sodium-dependent inorganic phosphate transporter-2b protein levels in the lungs. High dietary consumption of Pi stimulated pulmonary Akt activity while suppressing the protein levels of tumor suppressor phosphatase and tensin homolog deleted on chromosome 10 as well as Akt binding partner carboxyl-terminal modulator protein, resulting in facilitated cap-dependent protein translation. In addition, high dietary Pi significantly stimulated cell proliferation in the lungs of K-ras(LA1) mice. CONCLUSIONS: Our results showed that high dietary Pi promoted tumorigenesis and altered Akt signaling, thus suggesting that careful regulation of dietary Pi may be critical for lung cancer prevention as well as treatment.</P>
