A repeated-measures experiment design including two between-unit factors and one within-unit factor was performed in order to examine the influence of gibberellic acid on cherry fruit quality. One of the two between-unit factors had two levels represented by two cherry cultivars ('Van', 'Sunburst') and the other consisted of two treatments: spraying with gibberellic acid and spraying with pure water as a control. An experimental unit was a cherry branch on which 20 cherries were sampled randomly and marked. The three variables which describe ripeness of cherries were measured over 6 time points at three or four day intervals during maturation. After picking the cherries, measurements of fruit firmness were made on 3 different sides of each marked cherry. The univariate and multivariate repeated measures ANOVA was used for the analysis of two sets of data.

Randomly chosen high school choristers with extensive training in solfège syllables and Curwen hand signs ( N = 38) are asked to sight-sing two melodies, one while using Curwen hand signs and the other without. Out of a perfect score of 16, the mean score with hand signs was 10.37 ( SD = 4.23), and without hand signs, 10.84 ( SD = 3.96). A repeated-measures ANOVA revealed no statistically significant difference, F(1, 37) = .573, p = .454. These findings support the results of five earlier studies; however, because earlier studies were limited to students who were minimally trained in movable solfège syllables and Curwen hand signs, this study expands the knowledge base. Relationships between performance scores and instrumental experience, class grade, sight-singing experience, and hand sign experience were also examined. A pedagogical strategy for linking Curwen hand signs with students' preferred modes of learning (especially the kinesthetic mode) is recommended.

This study evaluated the effect of adding serration to the abutment-implant connection on torque maintenance before and after loading. Two implant systems with the same dimensions and connection design (internal 8˚morse taper octagon) were selected: one with non-serrated abutments (Simple line II) and the other one with serrated abutments (F & B). The removal torque value (RTV) was measured in two groups for each system: one group with one-piece abutments and the other group with two-piece abutments, before and after cyclic loading (n=10 in each group). The initial RTV of the abutment screw was measured with a digital torque meter. Each abutment received a cement-retained metal crown with 30° occlusal surface. Cyclic axial peak load of 75±5 N was applied to the implants for 500,000 cycles at 1 Hz. The post-load RTV was then measured. Two-way and repeated measures ANOVA, and independent t-test were applied to assess the effects of cyclic loading, connection design, abutment type, and their interaction on the percentage of torque loss (α=.05). Two-way ANOVA showed that serration of mating surfaces had a significant effect on torque maintenance before (P<0.001) and after (P=0.004) cyclic loading. Repeated measures ANOVA also showed that loading had a significant effect on the torque loss percentage (P< 0.01). Comparison of the groups with t-test showed that the torque loss of the serrated groups was lower than that of non- serrated groups. Despite the limitations of this study, the stability of the implant-abutment connection in the serrated design was higher than that of non-serrated group.

Background and aims: Postoperative pain has always been considered by surgeons because of its various complications. The aim of this study was to compare the effect of intravenous, subcutaneous and suppository morphine in reducing post-hysterectomy pain. Materials and Methods: In this clinical trial, 90 patients undergoing hysterectomy were randomized into three groups of 30 each using simple randomization, namely, intravenous, subcutaneous, and suppository morphine (10 mg). Before intervention and 4, 8, 12, and 16 hours after intervention, pain intensity was measured using visual analogue scale (VAS). Relative frequency of nausea, vomiting, itching, bradypnea, and apnea in all groups was recorded. Data were analyzed by SPSS version16.0. Results: Mean pain severity at 0 hour postoperatively (P=0.004), 4 hours postoperatively (P=0.009), 8 hours postoperatively (P=0.009), and 12 hours postoperatively (P=0.001) was significantly higher in the suppository morphine group than in the other two groups. There was no significant difference in pain severity at 16 hours postoperatively among the three groups (P=0.446). According to the results of repeated measures ANOVA, changes in pain severity at the five intervals were statistically significant in all three groups (subcutaneous, intravenous, and suppository morphine groups) (P<0.001). There was also a statistically significant difference in pain severity at the studied intervals among the three groups (P<0.001). The frequency of nausea (P=0.05) and vomiting (P=0.84) was higher in the suppository group than in the other two groups, although the difference was not statistically significant (P=0.05). Conclusion: The results of this study indicated better efficacy of subcutaneous and intravenous morphine in reducing post-hysterectomy pain compared with suppository morphine.

Abstract Background Gesture deficits in patients with schizophrenia are highly pronounced, and often linked to poor social functioning, motor abnormalities, and frontal lobe dysfunction. Although gesture performance has been associated to both negative and positive symptoms, its relationship to the severity of these symptoms is still unclear. Here, we examine how gesture performance varies as symptoms change. Furthermore, we aimed to compare gesture performance at two time points to healthy controls and first-degree relatives of schizophrenia patients. Gesture performance in relatives may indicate whether the deficits are associated with genetic liability to schizophrenia. We hypothesize that gesture performance in controls and relatives would be stable; while we expect improvement in patients when symptom severity declines. Methods The present study included 36 patients with schizophrenia (DSM-5 criteria; mean age 35.5 years), 28 unaffected first-degree relatives of schizophrenia patients (mean age 49.9 years) and 38 healthy controls (mean age 39.9 years). All three groups performed the Test for Upper-Limp Apraxia (TULIA), which includes pantomime (performance on verbal command) and imitative (performance upon demonstration) gestures, at two different time points, baseline and re-test (between 1–4 weeks). TULIA performance is recorded on videos and rated blind to diagnosis and stage. In addition, 22 of the 36 patients performed the TULIA at a follow-up session 6-months after baseline. Symptom severity was assessed with the Positive And Negative Syndrome Scale (PANSS). Analysis between the three groups and within patients across the different time points was done using repeated measures ANOVA in R. Results Symptom severity in patients declined between baseline and week 4 (T = 6.7, p&lt;0.001, PANSS total). A 3x2x2 repeated measures ANOVA revealed significant main effects of Group, Type of Gestures, as well as, a significant interaction between Group and Time Point (all F &gt; 3.8; p&lt;0.5) Post hoc analysis, bonferroni corrected, revealed that patients underperformed in both pantomime and imitative gestures compared to healthy controls (p&lt;0.0001) and relatives of schizophrenia patients, although this effect did not reach significance (p=0.26). Performance of pantomime gestures was poorer compared to imitative gestures. Interestingly, this pattern was also observed during the re-test time point (p&lt;0.0001), though gesture performance for imitative gestures significantly declined compared to baseline in patients (p&lt;0.05). In contrast, healthy controls performed better than both patients (p&lt;0.0001) and relatives (p-0.09) and remained stable during the re-test. Likewise, relatives performed intermediate between patients and healthy controls at both time points with scores reaching significance only at re-test (p&lt;0.001). At baseline, imitation was better than pantomime in relatives, but with re-test imitation scores declined while pantomime scores remained stable. Finally, at the 6-month follow-up patients still exhibited lower gesture performance compared to baseline (F=22.25; p&lt;0.05). Discussion Gesture performance in schizophrenia patients remained significantly impaired across time-points, suggesting an extended effect on poor social functioning despite symptom change. In addition, schizophrenia patients and their relatives showed a significant impairment when performing imitative gestures during the re-test compared to baseline. These results call for interventions specifically targeting gesture and social cognition, which would greatly improve patients’ quality of life. Finally, our findings suggest a trait component to gesture behavior that might be linked to genetic liability to psychosis.

Abstract Piglets are born wet, and evaporation of that moisture decreases body temperature, increasing the risk of mortality. The objective of this study was to compare the effect of two commercially applicable methods for drying piglets at birth on piglet rectal temperature over 24 h after birth. The study was carried out in standard commercial farrowing facilities with 52 litters, using a completely randomized design with three Drying Treatments: Control (not dried); Desiccant (dried at birth using a cellulose-based desiccant); Paper Towel (dried at birth using paper towels). Litters were randomly allotted to treatments at the birth of the first piglet. At birth, piglets were individually identified, and the treatment was applied. Rectal temperature was measured at 0, 10, 20, 30, 45, 60, 120, and 1,440 min (24 h) after birth. Data were analyzed using a repeated measures model with PROC MIXED of SAS, with litter as the experimental unit and piglet a subsample of the litter. The model included the fixed effects of treatment and time (as a repeated measure), and the interaction. There was no effect (P &gt; 0.05) of treatment on temperature at birth, or 10 or 1,440 min after birth. Piglet temperatures between 20 and 120 min after birth were similar (P &gt; 0.05) for the Desiccant and Paper Towel treatments, but were greater (P ≤ 0.05) than the Control. The effect of birth weight on the response to Drying Treatment was evaluated by dividing the data into Light (&lt;1.0 kg), Medium (1.0 to 1.5 kg), or Heavy (&gt;1.5 kg) piglet Birth Weight Categories. Piglet rectal temperature data at each measurement time were analyzed using a model that included the fixed effects of Birth Weight Category, Drying Treatment, and the interaction. Temperatures of Light piglets were lower (P ≤ 0.05) than those of Heavy piglets between 20 and 120 min after birth, with Medium piglets being intermediate and generally different to the other two weight categories at these times. The difference in temperature between Light as compared with Medium or Heavy piglets was greater for the Control than the other two Drying Treatments at 60 min after birth. These results suggest that drying piglets at birth is an effective method to reduce rectal temperature decline in the early postnatal period, especially for low birth weight piglets.

This study determined whether a five repetition-maximum Bulgarian split-squat (5RM BSS) could potentiate a 0-5, 0-10, and 0-20 m (meter) sprint performance. Seven men were assessed in the 5RM BSS (a linear position transducer measured peak power [PP] and force [PF] for each leg), and completed two post activation potentiation (PAP) sessions. One session involved a control condition (CC) of 4 minutes (min) rest; the other the 5RM BSS. Participants were assessed in baseline sprints, and sprints of 15 seconds, 2, 4, 8, 12, and 16 min post-PAP intervention. A repeated measures ANOVA (p < 0.05) calculated significant changes in sprint times. The best potentiated time for each interval was also compared to the baseline. Spearman’s correlations (r; p < 0.05) calculated relationships between absolute and relative strength, PP and PF, with percent potentiation in sprint times. The BSS did not potentiate speed at any time, although there was great individual variation. The best 0-5 m time was significantly different from the baseline (p = 0.022), with no differences between PAP conditions. Significant correlations were found between strength and sprint potentiation at 16 min for the 0-5 m interval, and at 8 min and the best times for the 0-20 m interval (r = -0.786 to -0.893). There were correlations between PP and PF for each leg with sprint potentiation from 2-12 min across all intervals (r = -0.786 to -0.964). Stronger individuals who generate greater PP and PF in a 5RM BSS will be more likely to potentiate 20-m sprint performance.

The purpose of this study was to determine the effects of exercise intensity on active and passive intestinal glucose absorption. Eight trained runners (age = 23 ± 2 y; VO2max = 62.1 ± 5.8 mL · kg−1 · min−1) performed a 1 h resting experiment and three 1 h treadmill experiments at 30, 50, or 70% VO2max in a thermoneutral environment. Immediately prior to each experiment, euhydrated subjects ingested a solution containing two non-metabolizable glucose analogs, 3-O-methyl-D-glucose (3MG; actively absorbed; 5 g) and D-xylose (passively absorbed; 5 g). During the following 5 h, all urine was collected and the amount of 3MG and D-xylose in the urine was determined. Using repeated measures ANOVA, a significant (P < 0.05) reduction in urinary excretion of each carbohydrate was observed at 70% VO2max compared to the other intensities suggesting that both active and passive intestinal absorption of glucose may be reduced during prolonged running at this intensity.

This study was carried out using 120 multiparous Awassi ewes during breeding season to compare the effect of 6 times reusing of CIDR short term (6 days) on hormonal and reproductive performance. Ewes were equally and randomly allotted into 6 consecutive oestrus synchronization treatments. For group CIDR6×1, the ewes (n = 20) received new CIDR for 6 days with 300 IU of eCG at withdrawal time. For the other 5 groups, the same protocol was used, differing only by the use of the same CIDR for a second time in CIDR6×2, for a third time in CIDR6×3, for a fourth time in CIDR6×4, for a fifth time in CIDR6×5, and for a sixth time in CIDR6×6. Oestrus was detected using a vasectomized ram starting 12 h after progestagen withdrawal and repeated every 12 h up to 84 h. Blood samples were collected at withdrawal time (Day 6). Progesterone serum concentrations were measured using commercial ELISA kits and micro-titrimetric plates. Timed insemination was performed 48 h after CIDR withdrawal. Pregnancy and number of fetuses were diagnosed by ultrasonography at Day 23 after insemination and confirmed at Day 35 and 60. Comparisons among groups was evaluated using chi-square (χ2) test in all parameters except hormones levels, which was analysed by repeated-measures ANOVA, using SAS (SAS Institute Inc., Cary, NC, USA, 2000). The results revealed that there is no significant difference between the percentages of ewes detected in heat in groups CIDR6×1, CIDR6×2, and CIDR6×3 (55, 70, and 55%, respectively). While, the percentages of ewes detected in heat in group CIDR6×2 was significantly (P ≤ 0.05) higher than in groups CIDR6×4, CIDR6×5, and CIDR6×6 (35, 35, 31.58%, respectively). On the other hand, pregnancy rate was significantly (P ≤ 0.05) higher in CIDR6×2 (65%; 13/20) than CIDR6×3, CIDR6×4, CIDR6×5, and CIDR6×6 (30, 30, 30, and 15.79, respectively). No significant difference was detected in pregnancy rate between CIDR6×1 and CIDR6×2. No significant differences were detected in progesterone between CIDR6×1 and CIDR6×2, CIDR6×3, CIDR6×4, CIDR6×5, and CIDR6×6 (1.73, 1.67, 1.87, 1.57, 1.60, and 1.36 ng mL–1, respectively). These results indicated that reusing of CIDR devices for short term are efficient in synchronizing oestrus in ewes.

Background: There are several serological tests used in the diagnosis of melioidosis. However, the interpretation of the results can be problematic in endemic areas because there might be a high background positivity due to previous exposure. Objective: This study aimed to determine the usefulness of Indirect Immunofluorescent Antibody (IFA) IgM and IgG in the diagnosis of melioidosis and the time for seroconversion. Methodology: We prospectively studied the trend of IFA IgM and IgG in 40 patients with culture-confirmed melioidosis over three months at six different time points (days 1, 8, 15, 30, 60, and 90). Results: From the results, 37.5% and 32.5% of patients had IFA IgM and IgG of ≤ 1:20 respectively on day 1 when the blood culture was positive. The natural log (ln) of the titres was used for the analysis. Repeated measures ANOVA showed significant changes in both IgM (p= 0.001) and IgG (p= 0.045) respectively throughout six sampling time points. Both the means of ln IgM and ln IgG peaked at day 15. At day 90, mean ln IgG remained high but mean ln IgM dropped to a level below that of day one. All culture-confirmed melioidosis patients recorded a maximum IFA IgM titre of at least 1: 80, but all subsequently dropped to below this level at day 90. Conclusion: IFA IgM is a more useful diagnostic serological marker than IFA IgG in acute melioidosis. Bangladesh Journal of Infectious Diseases 2020;7(2):61-66

Introduction: In the spaceflight, during launch and re-entry, the crew is exposed to acceleration ranging from +4Gx to +8Gx in nominal conditions. This study was conducted to assess the changes in cardiorespiratory parameters, namely, heart rate (HR), electrocardiogram (ECG), respiratory rate (RR), and SpO2 on exposure to simulated +Gx acceleration. Material and Methods: Fifteen randomly selected healthy male volunteers participated in the study. They were exposed to a simulated acceleration profile consisting of two peaks in the high-performance human centrifuge; first peak of +4Gx for 30 s and second peak of+8Gx for 30 s. The cardiorespiratory parameters were monitored and recorded during the acceleration exposure. The data were compiled and analyzed using one-way repeated measures ANOVA. Results: Significant increase in HR was observed on exposure to +4Gx (110.4 ± 16.7 bpm; P < 0.001) in comparison to the baseline value (80.5 ± 7.5 bpm). However, the changes in the HR at +8Gx were not significant in comparison to baseline as well as +4Gx values. On the other hand, RR indicated a significant increase on exposure to +8Gx (25.2 ± 5.8 breaths/min) in comparison to the baseline (15.1 ± 1.6 breaths/min; P = 0.001) and +4Gx (19.0 ± 6.1 breaths/min; P = 0.009) values. SpO2 showed a significant reduction at +8Gx (94.2 ± 3.8%) in comparison to baseline (98.9 ± 0.3%; P = 0.004) and +4Gx (96.9 ± 1.5%; P = 0.003). ECG did not show any evidence of arrhythmia during the exposure to +Gx acceleration. Conclusion: The insignificant changes in the HR at peak of +8Gx indicate less pronounced effects on the smaller hydrostatic gradient in +Gx acceleration unlike +Gz acceleration. However, the findings of the study point towards a significant increase in respiratory rate and reduction in SpO2 at +8Gx.
