Honey Yield

This study was carried out to determine the effects of additive feeding with pollen and water on honey yield, colony population, winter loses and wintering ability of colonies in pine honey production season in Muğla province of Turkey. Total twenty honeybee colonies had similar physiological pattern (queen age, genotype, amount of adult worker bees (number of frames covered with adult worker bees), sealed brood areas (cm2) and food stocks) were used and randomly divided into four groups. Three of them were fed extra with pollen+water, pollen and water. The control colonies were not given additive foods. Honey yield in pollen+water, pollen, water and control groups were found to be 24.2±1.1, 17.3±0.8, 16.3±1.0 and 12.0±0.6 kg/colony respectively. Group means were statistically significant. From September 25 to February 15 (wintering), losses of the adult worker bees in pollen+water, pollen, water and control groups were 50%, 69%, 68% and 82%, decrease of sealed brood areas in the groups were 48%, 66%, 68% and 85%, respectively. Wintering ability of pollen+water, pollen, water and control groups were found to be 92.1±3.2, 70.4±17.8, 67.1±16.7 and 51.0±21.2% respectively. The results showed that additive feeding in pine honey production season, especially feeding with both pollen+water provided nearly 100% more honey production and 80% better wintering ability than the control group. In addition, feeding with only pollen or water had similar positive effect (approximately 40%) better than control group

The purpose was to examine and compare the longer-term generalization between 2 different practice dosages for a single-session treadmill slip-perturbation training when reexposed to an overground slip 6 months later. A total of 45 older adults were conveniently assigned to either 24 or 40 slip-like treadmill perturbation trials or a third control group. Overground slips were given immediately after initial training, and at 6 months after initial training in order to examine immediate and longer-term effects. The performance (center of mass stability and vertical limb support) and fall percentage from the laboratory-induced overground slips (at initial posttraining and at 6 mo) were measured and compared between groups. Both treadmill slip-perturbation groups showed immediate generalization at the initial posttraining test and longer-term generalization at the 6-month retest. The higher-practice-dosage group performed significantly better than the control group (P < .05), with no difference between the lower-practice-dosage and the control groups at the 6-month retest (P > .05). A single session of treadmill slip-perturbation training showed a positive effect for reducing older adults’ fall risk for laboratory-induced overground slips. A higher-practice dosage of treadmill slip perturbations could be more beneficial for further reducing fall risk.

AbstractMany medical education journals use Twitter to garner attention for their articles. The purpose of this study was to test the effects of tweeting on article page views and downloads.The authors conducted a randomized trial usingAcademic Medicinearticles published in 2015. Beginning in February through May 2018, one article per day was randomly assigned to a Twitter (case) or control group. Daily, an individual tweet was generated for each article in the Twitter group that included the title, #MedEd, and a link to the article. The link delivered users to the article’s landing page, which included immediate access to the HTML full text and a PDF link. The authors extracted HTML page views and PDF downloads from the publisher. To assess differences in page views and downloads between cases and controls, a time-centered approach was used, with outcomes measured at 1, 7, and 30 days.In total, 189 articles (94 cases, 95 controls) were analyzed. After days 1 and 7, there were no statistically significant differences between cases and controls on any metric. On day 30, HTML page views exhibited a 63% increase for cases (M=14.72, SD=63.68) when compared to controls (M=9.01, SD=14.34; incident rate ratio=1.63, p=0.01). There were no differences between cases and controls for PDF downloads on day 30.Contrary to the authors’ hypothesis, only one statistically significant difference in page views between the Twitter and control groups was found. These findings provide preliminary evidence that after 30 days a tweet can have a small positive effect on article page views.

Background. The problem of diagnosis and treatment of papillary thyroid cancer (PTC) are radioiodine resistant metastases (RIRM). An urgent issue is the possibility of their early prediction and diagnosis based on the detection of cytomorphological features of the PTC and its metastases, which correlate with the development of radioiodine (RI) resistance. Purpose – detection of cytomorphological features of primary PTC and its metastases in patients who subsequently showed resistance to 131I therapy, compared with the control group of patients who achieved a positive effect of 131I therapy. Materials and Methods. A comparative analysis of morphological features in histological conclusions and the study of cytological characteristics in the fine-needle aspiration (FNA) smears of primary PTC and their primary metastases, as well RIRM оf experimental and control groups of patients were conducted. The experimental group consisted of 152 patients who showed resistance to RI therapy, the control group – 161 patients who achieved a positive effect of RI therapy. Statistical processing was done in Statistica 12. Results and discussion. It is shown that the frequency of follicular structures in the material of primary PTC of patients with a positive effect of 131I therapy is significantly higher, and the frequency of necrotic changes is significantly lower than in patients with the development of RIRM (p <0.05 by criterion χ2). The frequency of follicular structures in the histological material and FNA smears of primary metastases of patients with a positive effect of 131I therapy is significantly higher, and oxyphilic changes are significantly lower than in patients with the development of RIRM (p <0.05 by criterion χ2). Oxyphilic changes were observed significantly more often in the RIRM compared with primary metastases of the control group (p = 0.03). It was proved that cystic changes are significantly more common in FNA smears and histological material of RIRM in comparison with primary metastases of experimental and control groups of patients (p <0.05). Conclusions. TThe use of the presence of oxyphilic and cystic changes in the FNA smears and histological material of metastases of the PTC as prognostic factors of RI resistance is proposed. The presence of follicular structures in the materials of primary PTC and metastases can be a prognostic factor of effective RI therapy.

Effects ofEpimediumextract and its constituent icariin on peripheral nerve repair were investigated in a crush injury rat model. Animals were divided into four groups: sham, control,Epimediumextract, and icariin groups. At postoperative weeks 1, 2, 4, and 8, nerve regeneration and functional recovery were evaluated by sciatic functional index (SFI), nerve electrophysiology, nerve pinch test, and muscle wet weight. Results showed that at 2 and 4 weeks after surgery rats in theEpimediumgroup displayed a better recovery of nerve function than that in the icariin and control groups, with better recovery in the icariin group than in the control group. The nerve pinch test showed that nerve regeneration was greater in theEpimediumgroup and the icariin group as compared to the control group. In addition, the muscle wet weight in theEpimediumgroup was significantly improved when compared with the icariin group, and the improvement in the icariin group was better than that in the control group at 8 weeks after operation. Our findings suggest thatEpimediumextract effectively promotes peripheral nerve regeneration and improves the function of damaged nerves.

Abstract Introduction: The aim of this study was examine the relationship between ability of safe falls and occurrence injuries from the effect of falls, among blind children. Material and methods: More than one hundred children (10-16 years old) was in research and control groups. In the research group was 51 blind people, in control group 66 sighted in a proper manner. Test of Susceptibility to Injury During the Falls (TSIDF) by Kalina and interview directed to determine the number and frequency of falls and their consequences (number and type of injuries) and selected lifestyle factors were used as a research tools. Results: Blind children made more mistakes in test (TSIDF) than their non-disabled peers (although they are trained to safe falls). This may prove that a high susceptibility to injury of the children from the research group. However blind people had more injuries after the falls. Study confirmed positive effect of physical activity on the level of safe falls skills. Conclusion: Physical fitness, physical activity and especially exercises of safe falls skills can be important element of prevention of falls. This concern to high-risk groups, such as blind people.

Purpose. To evaluate the effect of preoperative intravitreal bevacizumab (IVB) injection on the surgical outcome of Ahmed glaucoma valve (AGV) implantation according to the angle status in neovascular glaucoma (NVG) eyes. Materials and Methods. This retrospective study included 70 NVG patients who underwent AGV implantation and were followed up for at least 12 months. An IVB injection before AGV implantation was administered to 45 eyes (IVB group), while it was not administered to 25 eyes (control group). Subgroup analyses were done at different stages in terms of the extent of peripheral anterior synechiae (PAS). Results. Mean follow-up period after AGV implantation was 27 ± 15 months. The IVB group showed higher prevalence of the eyes with less than 50% of PAS than that of the control group (78% versus 44%). The overall success rate 1 year postoperatively was 80% and 64% for the IVB and control groups, respectively (P=0.142). When PAS extent was less than 50%, preoperative IVB had a marginally positive effect on surgical outcome (HR = 0.39, P=0.064, per 1-time IVB injection). Conclusions. Preoperative IVB may enhance the success rate of AGV implantation in NVG eyes, before PAS has extensively formed. Further prospective randomized studies controlling the extent of PAS are warranted.

<p>This paper attempts to investigate the effect of using cell phone dictionaries on improving male and female Iranian high school EFL learners’ spelling. To this end, ninety participants were randomly selected from Dinodanesh and Etrat high schools in Lordegan city, and they were given a spelling pretest based on their course book. Then sixty subjects whose scores were within the range of one standard deviation above and below the mean were selected as homogeneous and divided into experimental and control groups. Using cell phone dictionaries was conducted in eight class session, during which experimental group received training with cell phone dictionaries while the control group only received training without any cell phone dictionaries. The data were collected via a pretest and a posttest. The analysis of the test scores using t-test revealed that the experimental group did statistically better in the test. The results revealed that using cell phone dictionary had positive effect on improving EFL learners’ spelling. At the end, a two-way ANOVA was run to compare the two groups plus the effect of gender on such performance. The results indicated that treatment have an effect on the improving of both male and female EFL learners’ spelling.</p>
