Salmonella Enteritidis colonizes the intestinal tract of poultry and causes foodborne illness in humans. Reduction of Salmonella Enteritidis colonization in the intestinal tract of poultry reduces potential carcass contamination during slaughter. The purpose of this study was to determine the effect of an avian-specific probiotic combined with Salmonella Enteritidis-, Salmonella Typhimurium-, and Salmonella Heidelberg-specific antibodies on the cecal colonization and organ invasion of Salmonella Enteritidis in broiler as well as on body weights. The treatment group was defined as chicks spray-vaccinated with Avian Pac Plus at the hatchery and given Avian Pac Plus for the first 3 days after placement. An intermediate treatment was given at 10 and 14 days, 2 days prior to vaccination and 2 days postvaccination. All birds were vaccinated with Newcastle disease vaccine, La Sota virus (one drop/eye) at 12 days of age. A final treatment was given 3 days preslaughter. The control group was defined as chicks not given Avian Pac Plus at any time. Six hours after oral administration of the probiotic suspension (treatment group) or water (control group) at placement, the chicks were challenged with Salmonella Enteritidis. All chickens were orally inoculated with 0.25 ml of Salmonella Enteritidis that contained 4 × 107 CFU/1.0 ml. Cecal colonization and organ invasion were evaluated for Salmonella Enteritidis on days 0, 1, 3, 7, 10, 17, 24, 31, 38, and 41. The probiotic-treated group had a significantly lower concentration of Salmonella Enteritidis cecal colonization at days 3, 7, 10, 17, 24, 31, 38, and 41 when compared to the nontreated, control group (P < 0.05). Similarly, there was a significant difference (P < 0.05) in the isolation of Salmonella Enteritidis from the internal organs (liver and spleen) when probiotic-treated and nonprobiotic-treated groups were compared. There was no significant difference (P > 0.05) in the mean body weight between the two experimental groups at each collection period. These results indicated that a combination of Lactobacillus acidophilus, Streptococcus faecium, and Salmonella Enteritidis, Salmonella Typhimurium, and Salmonella Heidelberg-Specific antibodies have a beneficial effect in reducing the colonization of Salmonella Enteritidis in market-aged broilers.

Salmonella typhimurium colonizes the intestinal tract of poultry and causes food-bome illness in humans. Reduction of S. typhimurium colonization in the intestinal tract of poultry reduces potential carcass contamination during slaughter. The purpose of this study was to determine the effect of an avian-specific probiotic and S. typhimurium-specific antibodies on the colonization of S. typhimurium in broilers and on body weights. Broiler chicks were spray-vaccinated at the hatchery with the commercial product, Avian Pac Plus, which contains Lactobacillus acidophilus, Streptococcus faecium, and S. typhimurium-specific antibodies. At placement, these chicks were administered Avian Pac Plus in the water. Six hours postplacement, chicks were orally challenged with 1.8 × 107 CFU of S. typhimurium. Chicks were administered Avian Pac Plus for two additional days postchallenge. Chicks were evaluated for S. typhimurium colonization and shedding every 3 to 4 days for the first 2 weeks and every 7 days for 6 weeks. The mean cecal and colonic concentration of S. typhimurium from the Avian Pac Plus-treated group was significantly lower at day 31 (P = 0.0001), day 38 (P = 0.0005), and day 43 (P = 0.0001) than the nontreated control group. These results indicated that a combination of Lactobacillus acidophilus, Streptococcus faecium, and S. typhimurium-specific antibodies have a beneficial effect in reducing the colonization of S. typhimurium in market-aged broilers.

Organ Invasion

Salmonella enteritidis (SE) is of great concern to the poultry industry due to the organism's ability to penetrate the intestinal mucosa of the laying hen and subsequently colonize the ovaries and yolk membrane. The resultant subclinical infection can lead to SE infection of raw eggs and egg products. Interference with the ability of the organism to invade has been linked to the activation and recruitment of inflammatory polymorphonuclear cells, heterophils, to the lamina propria of the intestinal tract.Recently it has been established that heterophil activation and increased resistance to SE organ invasion can be accomplished by the administration of SE-immune lymphokines (SE-ILK) obtained from supernatants of concanavalin-A stimulated SE immune T lymphocytes from SE hyperimmunized hens. Invasion of SE into the lamina propria provides a secondary signal for directing activated heterophils to the site of SE invasion.

The effects of audience response systems (ARS) on students' academic success and their perceptions of ARS were examined in this study. Participants, comprising 44 undergraduate students, were randomly assigned to a control or treatment group. The course design was the same for both groups and the instructor prepared the multiple-choice questions in advance; students in the control group responded to these questions verbally whereas the treatment group used ARS. Two paper-based examinations were used to measure the learning of concepts and skills that were taught. Students' perceptions of ARS were collected via a questionnaire. Results showed that ARS usage has a significant learning achievement effect in the first 4 weeks but not at the end of the second 4 weeks. There was no significant difference in retention between either group. Students perceived the ARS tool positively, finding it very enjoyable and useful.

AbstractWe investigated the efficacy of donepezil for mild cognitive impairment in Parkinson’s disease (PD-MCI). This was a prospective, non-randomized, open-label, two-arm study. Eighty PD-MCI patients were assigned to either a treatment or control group. The treatment group received donepezil for 48 weeks. The primary outcome measures were the Korean version of Mini-Mental State Exam and Montreal Cognitive Assessment scores. Secondary outcome measures were the Clinical Dementia Rating, Unified Parkinson’s Disease Rating Scale part III, Clinical Global Impression scores. Progression of dementia was assessed at 48-week. Comprehensive neuropsychological tests and electroencephalography (EEG) were performed at baseline and after 48 weeks. The spectral power ratio of the theta to beta2 band (TB2R) in the electroencephalogram was analyzed. There was no significant difference in the primary and secondary outcome measures between the two groups. However, the treatment group showed a significant decrease in TB2R at bilateral frontotemporoparietal channels compared to the control group. Although we could not demonstrate improvements in the cognitive functions, donepezil treatment had a modulatory effect on the EEG in PD-MCI patients. EEG might be a sensitive biomarker for detecting changes in PD-MCI after donepezil treatment.

BACKGROUND: Cervicogenic headache (CGH) is a common condition that results in significant disability. To treat this dysfunction, Mulligan described sustained natural apophyseal gliders (SNAGs) as a manual therapy approach. However, only inconclusive short-term evidence exists for treating CGH with SNAGs. OBJECTIVE: The present study aims to investigate the effect of SNAGs in the treatment of CGH. METHODS: Fourty female patients ranging from 20 to 40 years with CGH were randomly assigned to two groups: 20 in a treatment group and 20 in a control group. SNAGs were applied to the treatment group while the control group received placebo treatment. Both groups received their respective treatment for 20 minutes, alternately three times per week, for a total of 12 times in four weeks. The outcome measures were the Neck Disability Index (NDI) and the Visual Analogue Scale (VAS). Participants were assessed at baseline and at the end of each week. The data was analyzed using SPSS version 20. Independent t-testing was used to reveal changes between groups. One-way ANOVA was used to determine changes within groups. The level of significance was P< 0.05. RESULTS: Twenty participants (100%) in the treatment group and 17 (85%) in the control group had a history of headache aggravation with active movements or passive head positioning. There was no significant difference at baseline (p> 0.05), indicating that both groups were homogeneous at the time of recruitment. The p value (p< 0.05) showed a significant difference in pain and level of disability at three and four weeks (p< 0.05) in patients treated with SNAGs. However, the cervical range of motion (ROM) showed a statistically significant improvement in flexion and extension in the treatment group (p< 0.05) while there was no significant improvement in side flexion and rotation ROM in both groups (p> 0.05). CONCLUSION: This study found that SNAGs were effective in reducing pain and neck disability and improved ROM in females with CGH.

Background: Amplification of inflammation in acute exacerbation of chronic obstructive pulmonary disease (COPD) increases inflammatory mediators and oxidative stress in the airways, pulmonary and systemic circulation that are characterized by increased plasma level of IL-6 and MDA, resulting in worsening of clinical symptoms. Xanthones in mangosteen pericarp have anti-inflammatory and antioxidant effects, potentially as an adjuntive therapy in acute exacerbations of COPD. Methods: The aim of this study was to determine the effect of mangosteen pericarp extract to clinical improvements, plasma level of IL-6 and MDA of acute exacerbation COPD patients. A clinical trial of experimental with pretest and posttest was conducted on 34 acute exacerbation of COPD patients in Dr. Moewardi Hospital Surakarta and Dr. Ario Wirawan Lung Hospital Salatiga from April until May 2016. The sample was taken by consecutive sampling. Subjects were divided by randomized double blind technique into the treatment group (n=17) received mangosteen pericarp extract 2x1100mg/day and control group (n = 17) received placebo. Clinical improvements were measured in CAT score and length of stay. CAT score, plasma level of IL-6 and MDA were measured on admission and at discharge. Length of stay based on the number of days of care in hospitals. Results: There was significant difference (p=0,011) towards decreased of IL-6 plasma level between treatment group (-2,17 ± 3,46 pg/ mL) and control group (+1,67 ± 6,81 pg/mL). There were no significant difference towards decreased of length of stay (p=0,34) between treatment group (4,12 ± 1,54 days) and control group (5,24 ± 2,49 days), towards decreased of CAT score (p=0,252) between treatment group (-19,18 ± 3,96) and control group (-18,24 ± 2,75), and towards decreased of MDA plasma level (p=0,986) between treatment group (+0,03 ± 0,36μmol/L) and control group (+0,35 ± 1,58). Conclusions: The addition of mangosteen pericarp extract 2x1100mg/day during hospitalization was significantly lowered plasma levels of IL-6, but were not significant in lowering the CAT score, shortening the length of stay, and reducing the increase in plasma level of MDA.
