  • The objective of the present study was to investigate the effects of a mixture of functional oils (Essential, Oligo Basics Agroind. Ltda) on performance response of chickens challenged with coccidiosis and the determination of apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), the coefficients of protein and ether extract digestibility and intestinal morphology of broilers fed with diets containing Essential. In Exp. 1, a completely randomized design (CRD) was used, with one control diet without Essential inclusion with coccidiosis (Eimeria acervulina, Eimeria maxima, and Eimeria tenella) challenged birds and two different inclusion rates of Essential (1.5 kg/ton and 2 kg/ton) with coccidiosis-challenged and non-challenged birds for each inclusion rate, using 10 replicates and 50 birds per experimental unit. After 7 d of coccidiosis challenge, the livability was approximately 10% lower (p<0.05) for the control group. Intestinal lesion scores were lower (p<0.05) in the anterior intestine and the cecum for the chickens supplemented. Feed efficiency and growth rate were improved in birds supplemented with Essential (p<0.05) before the coccidiosis challenge and during the first 7 d post infection. In Exp. 2, a CRD was used, with one control diet without Essential inclusion and one diet with inclusion of Essential (1.5 kg/ton), using nine replications and 33 chicks per pen. The diets with Essential yielded approximately 4% higher AME (p = 0.003) and $AME_n$ (p = 0.001). Essential supplementation increased villus height in the jejunum on d 14 (p<0.05). Villus height:crypt depth ratio for the supplemented birds was larger (p<0.05) in the jejunum on d 7, larger (p<0.05) in the jejunum and ileum on d 14. In conclusion, these functional oils improved the energy utilization and the livability and decreased lesions caused by coccidiosis in supplemented birds.

  • Purpose: The aims of the current study were to evaluate the effects of superficial cold and heat after spine surgery on pain, satisfaction with pain control and comfort level, and to identify subjective responses and adverse effects. Methods: A prospective, single-blind, randomized controlled trial was utilized. The intervention group (n=36) received superficial cooling until the wound drain was removed and thereafter followed by superficial heating until discharge, while the control group (n=34) received only superficial cooling until wound drain was removed. Data were collected from August 4 to November 11 2014. Results: There was significant difference in pain according to time within groups (F=71.87, p<.001). However, we found no difference in pain between groups. The intervention group reported higher patient satisfaction with pain control (4 vs 3, z=-2.83, p=.005) and higher comfort level (5 vs 4, z=-4.12, p<.001) than the control group. Conclusion: Results indicate that sequential application of superficial cold and heat is a useful method in clinical practice for management of pain after spine surgery.

  • Mowing turfgrasses, especially fast growing species like perennial ryegrass, is one of the most time and money consuming tasks of their management. Trinexapac-ethyl (TE) is a popular plant growth regulator used to reduce mowing requirements, improve stress tolerance, and enhance turf quality. This study was conducted to investigate the effect of TE rate and frequency of applications on growth response and traffic tolerance of perennial ryegrass. The experiment was a split-plot laid out in a randomized complete block (RCB) design with three replications. TE was applied to main plots at 0.00, 0.25, and $0.50kg\;a.i.\;ha^{-1}$. Application pattern included an initial application, followed by two sequential applications at 6-wk intervals. Traffic treatment was applied to subplots with a cleated roller. Results demonstrated that TE consistently reduced vertical shoot growth, clippings dry weight, with maximum growth reduction of 59% and 65%, for 0.25 and $0.50kg\;a.i.\;ha^{-1}$, respectively, occurring at 2 weeks after initial TE treatment (WAT). Traffic also dramatically reduced vertical shoot growth and clippings dry weight. Overall, quality of perennial ryegrass was enhanced by sequential TE applications, however, turf quality and surface coverage reduced greatly under traffic, regardless of TE treatment. Total chlorophyll, chlorophyll a and chlorophyll b and total carbohydrates (TC) contents were also positively influenced following sequential TE application. Our results indicated that TE reduces mowing frequency and enhances turf quality rather than influencing traffic resistance.

  • Background: Nivolumab and pembrolizumab are antagonists of the programmed death-ligand 1 (PD-L1) receptor that function as immuno-oncological agents. This study aimed to evaluate the safety and efficacy of nivolumab and pembrolizumab in elderly patients in outpatient settings. Methods: The safety and efficacy of nivolumab and pembrolizumab were compared retrospectively among patients at the Veterans Health Service (VHS) Medical Center in Seoul, South Korea, from September 1, 2017 to August 25, 2018. Results: Eighty-seven patients were selected for the study. The median progression-free survival was 63 days for nivolumab (95% confidence interval (CI), [14 to 282]) vs. 243 days for pembrolizumab (95% CI, [22 to 348]) (p =0.04). The objective response rate (ORR) was 0% in the nivolumab group vs 5.6% in the pembrolizumab group (p =0.310). All the patients exhibited treatment-related adverse effects. More than 89% of the patients exhibited diseases of the gastrointestinal (GI) tract. Pneumonia, of grades three or higher, was the most common adverse effect, followed by weakness and anorexia. Conclusions: There was no statistically significant difference between the nivolumab group and the pembrolizumab group with respect to the ORR. The incidence and severity of the adverse effects in this study were higher than those of previous studies; however, these adverse effects are generally manageable in a real-world clinical setting. Further randomized controlled studies will be necessary to confirm these results in elderly patients.

  • Ginsenoside Rg3 (G-Rg3) is one of protopanaxadiol ginsenosides characteristic of red ginseng, steamed and dried ginseng (Panax ginseng), which has recently attracted much attention for its antitumor properties in vitro and in vivo animal models. Experimental studies have demonstrated that it could promote cancer cell apoptosis, inhibit cancer cell growth, the apoptosis of cancer cells, adhesion, invasion and metastasis, and also prevent an angiogenetic formation in prostate, breast, ovarian, colorectal, gastric, liver and lung cancer etc. It has shown the antitumor activities by modulation of diverse signaling pathways, including regulation of cell proliferation mediators (CDKs and cyclins), growth factors (vascular endothelial growth factor), tumor suppressors (p53 and p21), cell death mediators (caspases, Bcl-2, Bax), inflammatory response molecules ($NF-{\kappa}B$ and COX-2), protein kinases (JNK, Akt, and AMP-activated protein kinase) and Wnt/${\beta}$-catenin signaling. In addition, the combination of Rg3 and chemotherapeutic agents have synergistically enhanced therapeutic efficacy and reduced antagonistically side effects. Furthermore, it can reverse the multidrug resistance of cancer cells, prolong the survival duration and improve life quality of cancer patients. Taken together, accumulating evidences could provide the potential of G-Rg3 in the treatment of cancers and the feasibility of further randomized placebo controlled clinical trials.

  • Background: Epidural test doses containing epinephrine are an incomplete marker for the detection of inadvertent intravascular injection. Therefore, many investigators have attempted to find a more reliable marker as an alternative to epinephrine in adult patients anesthetized with enflurane. The present study was designed to test whether two different simulated intravenous test doses of isoproterenol could be used as a reliable marker for the detection of inadvertent intravascular injection in adult patients anesthetized with $O_2-N_2O$-enflurane. Methods: Forty healthy adult patients were anesthetized with 1% end-tidal enflurane and nitrous oxide after endotracheal intubation and were randomized to one of two groups according to the dose of isoproterenol. Group 1 and 2 (n = 20 each) received 3 ml of 1.5% lidocaine with 3 and 5 g isoproterenol intravenously, respectively, to simulate an intravascularly administered test dose. Heart rate (HR) and systolic blood pressure (SBP) were measured at 20-second intervals for 4 min after injection. Results: Mean maximal HR increases were $24{\pm}17$, $35{\pm}11$ bpm (P < 0.05), mean maximal SBP increases were $14{\pm}8$, $13{\pm}9$ mmHg and mean maximal SBP decreases $20{\pm}11$, $22{\pm}9$ mmHg following the IV injection of 3, $5{\mu}g$ isoproterenol, respectively. The incidence of hypotension was similar in both groups. Isoproterenol 3 and $5{\mu}g$ produced 75%, 100% sensitivity in the HR criteria ($\geq$ 20 bpm increase) and 60%, 70% sensitivity in the SBP criteria ($\geq$ 15 mmHg), respectively. Conclusions: These results indicate that based on the HR response, the epidural test dose containing $5{\mu}g$ isoproterenol to simulate an intravascular administration is a more reliable marker than $3{\mu}g$ isoproterenol in adult healthy patients during enflurane anesthesia.

  • Background: The aim of this preliminary study was to address variations of responses observed with different starting tumor sizes of 10 and 15 mm, and the effects of different doses of tamoxifen (TAM) on experimental rat mammary tumors. Materials and Methods: Thirty-five inbred female Sprague Dawley rats aged 43 days were administered with three weekly doses of N-methyl-N-nitrosourea (NMU) intraperitoneally (ip) at 50 mg/kg body weight. Animals were randomized (beginning from 10 mm tumor size) into four TAM-treated (50, 100, 200 and $500{\mu}g/day$) groups of six animals each, and another group (n=6) treated with TAM $100{\mu}g/day$ at starting tumour size of 15 mm. The animals were treated by oral gavage daily for 8 weeks before sacrifice. Results: Serum urea and creatinine, and overall physical tumor burden were significantly modulated in animals treated with variable doses of TAM compared to the untreated controls (n=5). Final body weight and tumor number were significantly different in the 10 mm-treated animals compared to those treated at 15 mm. There were no significant differences in histopathological features among all the groups. Conclusions: Our findings suggest the importance of standardizing tumour size and drug doses before initiation of treatment, particularly in the direct comparison of basic end-tumour physical parameters.

  • Objective: The long-term efficacy of microwave hyperthermia combined with chemoradiotherapy in treating nasopharyngeal carcinoma (NPC) with metastatic foci in cervical lymph nodes was evaluated. Methods: A total of 154 cases of N2 or N3 stage NPC were randomized into two groups: hyperthermia group (76 cases) and control group (78 cases). Both received cisplatin chemotherapy and radiotherapy. In addition, the hyperthermia group further received microwave hyperthermia to the metastatic cervical nodes with different patterns (before or after radiotherapy), heating temperatures (T90< $43^{\circ}C$ and $T90{\geq}43^{\circ}C$) and hyperthermia episodes (< 4 times, 4-10 times and > 10 times). Results: The 3-month and 5-year complete response (CR) rates of cervical lymph nodes in the hyperthermia group were significantly higher than those in the control group. The 5-year disease-free survival (DFS) rate and the 3-year / 5-year overall survival rate in the hyperthermia group were also significantly higher. There was no significant difference in 5-year metastatic rates. In the hyperthermia group, the 3-month and 5-year CR rates of T90< $43^{\circ}C$ treatment were significantly lower than with $T90{\geq}43^{\circ}C$ treatment. The CR rate was highest when the hyperthermia was performed 4-10 times. There were no significant differences in 3-month and 5-year CR rates between hyperthermia before or after radiotherapy treatment. Conclusion: Microwave hyperthermia combined with chemoradiotherapy can increase local control, DFS and 3, 5-year overall survival rates of patients with N2 ~ N3 stage NPC. The heating temperature should be over $43^{\circ}C$ with hyperthermia repeated 4-10 times.

  • BACKGROUND/OBJECTIVE: Several studies have reported that consumption of Salvia Hispanica L.,commonly known as chia seed, may exert beneficial effects on health outcomes. The main purpose of this study was to examine the influence of chia seed consumption as a mid-morning snack on short-term satiety. SUBJECTS/METHODS: Subjects (n = 24) were tested using a randomized, cross-over design consisting of three mid-morning snacks. Yogurt with no chia seed, yogurt with 7 g chia seed, and yogurt with 14 g chia seed were given to subjects on different test days. After subjects were asked to report visual analog scale (VAS) scores on sensory outcomes, ad libitum lunch was served, and energy intake of individuals was measured. RESULTS: VAS scores indicated that participants reported significantly lower scores for hunger (P = 0.033), prospective food consumption (P = 0.031), amounts of food that could be consumed (P = 0.017), desire for sugary foods (P = 0.015), and higher scores for satiety (P = 0.031) on the test days with 7 g and 14 g chia seed. Energy intake of individuals during ad libitum lunch was significantly lower when they consumed yogurt with 7 g or 14 g chia seed (P = 0.037). CONCLUSIONS: The study demonstrated that chia seed consumption as a mid-morning snack may induce short-term satiety in healthy individuals.

  • Limited information from human studies indicates that dietary quercetin supplementation influences blood lipid profiles, glycemic response, and inflammatory status, collectively termed cardiometabolic risks. We tested the hypothesis that quercetin-rich supplementation, derived from onion peel extract, improves cardiometabolic risk components in healthy male smokers in a randomized, double blinded, placebo-controlled parallel design. Randomly assigned subjects were instructed to take either the placebo (n=43) or 100 mg quercetin capsules each day (n=49) for 10 weeks. Anthropometric parameters and blood pressure were measured, and blood lipids, glucose, interleukin-6, and soluble vascular cell adhesion molecule-1 (sVCAM-1) were determined at baseline and after 10 weeks of quercetin supplementation. Quercetin-rich supplementation significantly reduced serum concentrations of total cholesterol (P<0.05) and LDL-cholesterol (P<0.01), whereas these effects were not shown in the placebo group. Furthermore, significant increases were observed in serum concentrations of HDL-cholesterol both in the placebo (P<0.005) and quercetin-rich supplementation group (P<0.001); however, changes in HDL-cholesterol were significantly greater in subjects receiving quercetin-rich supplementation than the placebo. Both systolic (P<0.05) and diastolic blood pressure (P<0.01) decreased significantly in the quercetin-rich supplementation group. Glucose concentrations decreased significantly after 10 weeks of quercetin-rich supplementation (P<0.05). In contrast, no effects of quercetin-rich supplementation were observed for the inflammatory markers-IL-6 and sVCAM-1. Daily quercetin-rich supplementation from onion peel extract improved blood lipid profiles, glucose, and blood pressure, suggesting a beneficial role for quercetin as a preventive measure against cardiovascular risk.
