The purpose of this research was to study the effect of knowledge of directional mis-tunings on the tuning accuracy of beginning and intermediate wind players. Subjects (N = 197) were instrumental wind players who tuned to either an For a B-flat with both their own instrument—a performance task—and the tuning knob of a variable-pitch keyboard—a perception task. The subjects were randomly assigned to one of three treatment groups: Group 1 knew that their instruments and the tuning knob were mis-tuned in the sharp direction; Group 2 knew that their instruments and the tuning knob were mistuned in the flat direction; and Group 3 had no information regarding direction of mistunings. Data demonstrated that only years of instruction significantly affected subjects' tuning accuracy. There were no significant differences due to treatment, instrument type, or tuning pitch. There were only 6 in-tune performance responses and 12 in-tune perception responses. Approaching the target pitch from above resulted in more sharp responses; approaching it from below resulted in more flat responses; and having no knowledge of direction of mistuning resulted in an equal number of sharp and flat responses. There were a greater number of flat responses in the first year of instruction and a greater number of sharp responses in the fourth year. Finally, there was consistent improvement from the first to the fourth year in both perception and performance tuning tasks.

Abstract Purpose: To compare the effect of intravitreal ranibizumab (IVR) or intravitreal dexamethasone implants (IVD) on regression of hyperreflective dots (HRDs) on optical coherence tomography (OCT) B-scan in patients with branch retinal vein occlusion (BRVO). Methods: 37 eyes of 37 patients with cystoid macular edema who received IVR or IVD and followed up for at least 12 months were included in this study. The patients were divided into three groups according to intravitreal treatment. Group 1 consisted of 12 eyes who received only IVD, group 2 consisted of 10 eyes who received only IVR on a pro re nata and group 3 consisted of 15 eyes who received both IVD and IVR. OCT parameters (CMT, number of HRDs, status of external limiting membrane (ELM) and ellipsoid zone (EZ)) and best-corrected visual acuity (BCVA) were compared between the groups over the follow-up time. HRDs were categorized as HRD in inner retinal layers (from the internal limiting membrane to the inner nuclear layer) or HRD in outer retinal layers (from the outer plexiform layer to the outer border of the photoreceptor layer).Results: There was no significant difference between groups in terms of BCVA, CMT, HRDs in the inner and the outer retinal layers at baseline visit. (p˃0.05 for all) Comparing the baseline values in all groups, a significant decrease was observed in CMT in the first year. (For group 1; p=0.013, group 2; p=0.010; group 3, p<0.001) The BCVA was significantly increased after 1 year in all groups. (p=0.001, p=0.006, p<0.001) The mean number of HRDs in inner and outer retinal layers were significantly decreased in group 1 and group 3. (For group 1; p<0.001, p=0.001, for group 3; p<0.001, p<0.001) However, there was no significant difference in terms of the mean number of HRDs in inner and outer retinal layers for group 2. (p=0.134, p=0.477) At the first year, the number of HRDs in inner and outer retinal layers was significantly lower in group 1 and group 3 than group 2. (For inner HRDs; group 1 vs. group 2 p=0.007, group 2 vs. group 3 p<0.001. For outer HRDs group 1 vs. group 2 p<0.001, group 2 vs. group 3 p<0.001.) The BCVA was higher in group 3 than group 2 at 1year. (p=0.048). There was no significant difference in terms of post-treatment CMT and the number of HRDs between group 1 and group3 in posthoc tests (p=0.621, p=0.876, and p=0.632).Conclusion: The reduction in HRDs at 12 months and better BCVA after IVD intimates that the HRDs should be considered as inflammatory markers in the follow-up of CME in BRVO. Thus, IVD injection could be more appropriate for patients with higher HRDs after BRVO.

Background: Pulmonary arterial hypertension (PAH) is a common complication of congenital heart disease (CHD) with uncorrected left-to-right shunts. Currently, no consensus guideline exists on the management of PAH-CHD in children, especially those who do not meet operability criteria. Objective: To compare survival between three groups of high-risk PAH-CHD, group 1: total correction including both surgical and percutaneous intervention, group 2: palliative treatment, and group 3: conservative with medical treatment group. Materials and Methods: All pediatric patients with PAH-CHD that underwent cardiac catheterization between January 1, 2008 and December 31, 2017 were retrospectively reviewed. Inclusion criteria were high risk PAH-CHD patients who had pulmonary vascular resistance (PVR) greater than 6 Wood unit·m² and PVR-to-SVR ratio greater than 0.3 evaluated in room air. Exclusion criteria were younger than three months of age, severe left side heart disease with pulmonary capillary wedge pressure greater than 15 mmHg, obstructive total pulmonary venous return, and single ventricle physiology. The Kaplan-Meier analysis was performed from the date of PAH diagnosis to the date of all-cause mortality or to censored date at last follow-up. Results: Seventy-six patients with a median age at diagnosis of 27.5 months (IQR 14.5 to 69.0 months) were included in this study. The patients were divided into three subgroups and included 38 patients (50.0%) in group 1, six patients (7.9%) in group 2, and 32 patients (42.1%) in group 3. The median follow-up time was 554 days (IQR 103 to 2,133 days). The overall mortality was 21.7%. One-year survival in patients with simple lesion in group 1 and 3 were 79.5% and 87.5% and patients with complex lesions in group 1, 2, and 3 were 93.8%, 83.3%, and 73.1%, respectively. The results showed that most mortalities occurred in the first year. There were no statistically significant differences in survival among difference types of treatment (log rank test, p=0.522). Conclusion: The mortality of high-risk PAH-CHD patients were not different among those who underwent corrective surgery, palliative, or conservative treatment. The mortality was high in the first year after PAH diagnosis and remain stable afterward. Management decision for an individual with high-risk PAH-CHD patients requires comprehensive clinical assessment to balance the risks and benefits before making individualized clinical judgment.

ABSTRACT Background: In recent years, the incidence and geographic distribution of dengue fever have greatly increased. Dengue fever is an acute viral disease transmitted by mosquitoes and is characterized by fever, headache, muscle and joint pain, skin rash, nausea and vomiting. The Mosquito Nest Eradication Program (PSN) through 3M Plus needs to be carried out continuously throughout the year, especially in the rainy season through the movement of housewife who monitor larvae. This study aimed to determine the effect of the dengue fever vector eradication model through the housewife movement of larva monitoring in the efforts of dengue fever prevention in Mojolangu Village, Malang City. Subjects and Method: This was a quasi-experiment using 2 treatment groups and 1 control group conducted at Mojolangu village, Lowokwaru district, Malang. A sample of 90 respondents divided into three groups was selected by purposive sampling. The dependent variable was DHF Prevention Efforts (Larva Monitoring). The independent variables were Dengue Fever Vector Eradication Model. The data were collected by questionnaire and observation. The data was analyzed by Kruskal-Wallis. Results: After being given treatment in group 1 (educated by health workers) and group 2 (trained cadres) the ability increased to be very good by 83% and 53%. In group 3 (control) his ability improved by 37%. Group 1 has the most effective influence in increasing knowledge and skills. Then group 2 with a significance value of <0.001 (p <0.005). Conclusion: Housewife are a resource in Family Empowerment and Intervention models. The eradication of dengue vectors needs regular monitoring and monitoring so that self-awareness and independence from the family can increase so that the degree of health can be achieved optimally.

Peste des petits ruminants poses a major threat to the development of small ruminant production. The objective of this study was to determine the comparative efficacy of amantadine hydrochloride (HCl), oxytetracycline long acting (LA) and levamisole in West African dwarf (WAD) goats experimentally infected with PPR. In addition to the presence of the characteristic clinical signs, complement ELISA and haem agglutination inhibition (HI) tests were used to confirm PPR infection in the West African dwarf goats, then treatment was instituted in the different groups namely, group 1 which was treated with amantadine HCl orally, oxytetracycline LA intramuscularly (IM) and levamisole per os. Group 2 was treated with oxytetracycline LA IM and levamisole. Group 3 was treated with levamisole while group 4 served as untreated control. The physiological parameters namely rectal temperature, pulse rate and respiratory rates of the different groups were recorded. The mortality rates in the different treatment groups were also recorded. The respiratory rates of the WAD goats increased as the infection progressed, but the increase was not significant (P>0.05). The treatment helped reduce the respiratory rates in the treated WAD. The rectal temperatures of all the animals in the different treatment groups increased only slightly as the infection progressed and was not significant (P>0.05). The percentage mortalities were 0% in Group 1, 25% in the Group 2, 50% in the treated group 3 and highest (75%) in the untreated group respectively. In conclusion, incorporation of specific antiviral agents like amantadine hydrochloride in the treatment regimen with oxytetracycline and levamisole particularly during the early stages of the infection can reduce morbidity and mortality of the disease to the barest minimum.

This study aimed to find out the parasitemia of DDY white mice infected with T. evansi of Pidie and Pemalang isolates obtained from Bbalitvet Bogor. A total of 12 mice were divided into 3 treatment groups. Group 1 (K1) without any treatment, group 2 (K2) was inoculated with 104 T. evansi Pidie isolate, and group 3 (K3) was inoculated with 104 T. evansi Pemalang isolate. Parasitemia examination was carried out every two days and the level of parasitemia was observed as well. Parasitemia examination was conducted until all mice died. Parasitemia of mice infected with Pidie isolate was characterized by rapid rise of parasitemia in blood (107-108/mL of blood) in a short time (2-4 days) since first parasitemia was detected and followed by death at day 4. The parasitemia of mice infected with Pemalang isolate increased in the blood (108-109/mL of blood) on day 4 and maintained for a few more days and then fluctuated for a few more days before the animal was dead. In conclusion, there was the difference in parasitemia level between Pidie and Pemalang isolates. Key words: Trypanosoma evansi, parasitemia, Pidie isolate, Pemalang isolate

This study examined the impact of learner proficiency on the occurrence and resolution of language-related episodes (LREs) in rehearsal of interactive speaking tasks and on the subsequent use of language items from LREs during performance of the same tasks in front of the class. Forty-eight learners from six intact English as a foreign language (EFL) classes at a Vietnamese high school were divided into three proficiency groups, each consisting of eight dyads. Group 1 was higher proficiency (HH) dyads; Group 2 consisted of mixed proficiency dyads (HL) and Group 3 was lower proficiency (LL) dyads. All the pairs rehearsed and then consecutively performed a problem-solving task and a debate task in two separate classroom lessons. The total data included 48 rehearsals and 48 corresponding performances collected during normal classroom hours. The results show that, overall, LL dyads encountered more language problems (more LREs) in rehearsal than HH dyads and they were less likely to resolve them successfully. However, they were able to use a majority of the correct resolutions in the performance as well as their higher proficiency counterparts. The lower proficiency learners were also found to employ memorizing and local rehearsing strategies to retain ideas and language items as they rehearsed for the upcoming performance. These findings have pedagogical implications for teaching and learning through tasks in EFL contexts and beyond.

Two experiments were conducted to determine if withdrawal of progesterone during the luteal phase of the oestrous cycle affected the ability of the ovine uterus to secrete prostaglandin F2α(PGF2α ) in response to oxytocin. In Experiment 1, 18 ewes were ovariectomized on Day 9 and Day 12 after oestrus. Ewes were subdivided into three treatment groups (n= 6 per group): Group-1 ewes underwent sham surgery; Group-2 ewes received oestradiol (OVX + O); and Group-3 ewes received oestradiol + progesterone (OVX + O,P). Oxytocin was administered to each ewe on Days 10, 13 and 15 after oestrus. Concentrations of 13,14-dihydro-15-keto-PGF2α (PGFM) were determined in samples of jugular venous blood for 2 h after oxytocin challenge. The magnitude of the PGFM response 24 h after ovariectomy was greater (P < 0·1) in ewes from which progesterone had been withdrawn (OVX + O) than in ewes in which progesterone was maintained (intact controls and OVX + O,P). Therefore, progesterone appears to exert an inhibitory effect on uterine secretory responsiveness to oxytocin which is removed by progesterone withdrawal. In Experiment 2, ewes were ovariectomized on Day 11 and assigned to 1 of 4 treatment groups (n = 6 per group): Group 1, no steroid replacement (OVX); Group 2, oestradiol replacement (OVX + O); Group 3, progesterone replacement (OVX + P); or Group 4, progesterone+oestradiol replacement (OVX + O,P). Ewes received oxytocin on Day 12 and Day 15. On Day 12, uterine secretory responsiveness to oxytocin was greatest in ewes in the OVX + O group (P < 0 · 1). Responsiveness was low in ewes in the OVX group, as it was in ewes in both groups that received progesterone replacement. Therefore, the increase in uterine secretory responsiveness to oxytocin following progesterone withdrawal is dependent on oestradiol replacement.

AbstractIn each of two experiments, 36 3 to 5-day-old dairy calves (male and female), were allotted to one of three groups: warm housing, milk feeding in teat-buckets twice a day (group 1); warm housing and computer-controlled milk feeding (group 2); and cold housing and computer-controlled milk feeding (group 3). The experiments were conducted from September until February. The daily gain in the first 4 weeks was lower for the calves in group 3 in both experiments and for calves in group 2 in experiment 2 because of lower food intake in this period. This was compensated for by an increased gain later. In spite of the different method of milk feeding, the activity rhythm was nearly equal among groups, but at week 6 and 10 the calves in group 1 spent more time with the head over the feeding table than the calves in the two other groups. The number of unrewarded visits per calf to the milk feeding station decreased from over 30 at week 4 to around 20 shortly before weaning. The frequency of sucking/licking pen-mates was almost negligible in all groups. In order to reduce the heat loss, the frequency of calves lying with body contact clearly increased by decreasing ambient temperature in cold housing.

In this study we examined the possibility that the reduced brown adipose tissue (BAT) thermogenesis in the Zucker obese rat may result from a limited capacity for enzymic conversion of thyroxine (T4) to triiodothyronine (T3) in BAT. A total of 34 lean and obese rats, approximately 4 mo old were divided into three treatment groups: group 1 (5 lean and 6 obese) was fed Purina rat chow for 21 days, and group 2 (5 lean and 6 obese) was fed a cafeteria diet for 21 days, and group 3 (6 lean and 6 obese) was fed Purina rat chow and maintained in the cold (8 +/- 1 degrees C) for 7 days. The lean and obese rats in all three groups of animals were matched closely for age and respective body weight. Activity of T4 5'-deiodinase was determined as the rate of T3 production from added T4 under controlled in vitro conditions. Serum T4 and T3 were determined by radioimmunoassay. The rate of T4-to-T3 conversion in BAT was similar in the lean and obese rats maintained at room temperature, whether fed rat chow or a cafeteria diet (approximately 40-50 pmol T3/scapular BAT depot per h). However, expressed per scapular BAT depot, lean rats exposed to cold displayed about a fivefold increase in BAT T3 production (P less than 0.0001), whereas only a small increase was observed in the cold-exposed obese rats. Serum T3 levels tended to be reduced in the Zucker obese rats. Our data indicate a reduced capacity for T3 production in Zucker rat BAT exposed to cold.(ABSTRACT TRUNCATED AT 250 WORDS)
