Treatment with linearly polarized light (LPL) is a widely used and recognized therapeutic method in human medicine for healing wounds, ulcers and a variety of other dermatological problems. Polarized light mobilizes the inadequately functioning defence mechanisms of the human body. The aim of the present experiment was to investigate the effect of LPL treatment on the udder of milking cows. Before the start of treatment, there was no significant difference between cows to be treated with LPL and the control cows in mean somatic cell counts (SCC) of milk samples taken separately by udder quarter and in the mean milk yield. The LPL treatment lasted for 20 min and was performed twice a day over a period of one month. Before treatment, the mean SCC of milk was 3.47 × 105 ± 910 in the group to be treated and 4.07 × 105 ± 920 in the control group. In a six-week period immediately after treatment, the mean SCC of the treated and the control group was 1.32 × 105 ± 825 and 2.63 × 105 ± 825, indicating a significant difference in favour of the treated group. Before the LPL treatment, the milk yield of cows in the group to be treated was 25.77 ± 1.2 kg/ day, while that of the control cows was 27.30 ± 1.4 kg/day. In a six-week period after treatment, the milk yield of cows in the treated and control groups was 28.83 ± 1.5 kg/day and 25.48 ± 1.4 kg/day, respectively. There is a significant difference between these values in favour of the treated group. The results show that a regular LPL treatment of the udder of cows can significantly reduce the SCC of milk and significantly increase the milk yield. The treatment can be applied during lactation without interfering with the milking regime.

This study was designed to assess the relative importance of Cl− and HCO3− secretion to mucociliary transport rate (MCT) in ex vivo porcine tracheas. MCT was measured in one group of tissues that was exposed to adventitial HCO3−-free solution while a parallel group was exposed to adventitial HCO3−-replete solution. After measurement of baseline MCT rates, acetylcholine (ACh) was added to stimulate submucosal gland mucous liquid secretion, and MCT rates were again measured. Before ACh addition, the mean MCT was higher in the HCO3−-free group (4.2 ± 0.9 mm/min) than in the HCO3−-replete group (2.3 ± 0.3 mm/min), but this difference was not statistically significant. ACh addition significantly increased MCT in both groups, but ACh-stimulated MCT was significantly lower in the HCO3−-free group (11.0 ± 1.5 mm/min) than in the HCO3−-replete group (17.0 ± 2.0 mm/min). A second series of experiments examined the effect on MCT of blocking Cl− secretion with 100 μM bumetanide. Before adding ACh, MCT in the bumetanide-treated group (1.0 ± 0.2 mm/min) was significantly lower than in the control group (3.8 ± 1.1 mm/min). ACh addition significantly increased MCT in both groups, but there was no significant difference between the bumetanide-treated group (21.4 ± 1.7 mm/min) and control group (19.5 ± 3.4 mm/min). These results indicate that ACh-stimulated MCT has greater dependence on HCO3− secretion, whereas the basal MCT rate has greater dependence on Cl− secretion.

Abstract. Title of the paper: Effect of soft flooring in free stalls on milk yield, fat, protein and somatic cell counts in dairy cattle Research conducted at the Experimental Farm Oberschleißheim focused on comparing milk yield, fat, protein and somatic cell counts in dairy cattle housed in free stalls with concrete slatted floor and rubber mats covering the concrete slatted floor. Data were collected from 49 cows in 53 lactation periods, which were divided into experimental group (n = 26) on rubber matted floor (EBG) and control group (n = 27) on concrete slatted floor (BBG). Housing conditions of both groups differed in kind of cubicles. EBG had soft rubber mat mattresses, BBG had cubicles with straw manure mattresses. Data analysed originated from the official milk performance testing of the "Landeskuratorium der Erzeugerringe für tierische Veredelung in Bayern e.V." and from activity counters worn by the cows. Statistical analysis resulted in a significant higher activity level of the EBG versus BBG. Milk yield and protein showed no significant difference between both groups, fat was significant higher in BBG. Somatic cell counts were significant lower in EBG. Data analysed regarding activity level classes showed a trend of decreasing milk yield and milk constituents with increasing activity. No evidence was found that soft floor results in higher milk yield. But a higher activity level of EBG cows might indicate a higher cow comfort on elastic floor.

Previous research has examined the utilisation of musical cues to improve the performance of cardiopulmonary resuscitation (CPR) delivered in training environments. We postulated a musical cue that is both contemporary and transcends cultures may improve CPR performance. Our aim was to establish whether chest compressions are performed with improved rate and depth if a song of a fixed beat (PinkFong’s ‘Baby Shark’ with a tempo of 115 beats per minute (bpm) and 15 beats in each verse) is played to a healthcare professional immediately before undertaking CPR compared to whale noises (a non-metronomic rhythm). 58 Participants of a paediatric conference (majority doctors) were randomly assigned to listen to a minute of Baby Shark (28) or whale song (30) and then undertake a minute of CPR. There was no significant difference in the mean compression rate between the Baby Shark and control groups, with the groups achieving 121 and 125 bpm, respectively (p=0.18). In relation to compression depth within the target zone, the Baby Shark group had more compressions completed within the target zone (55%) than the control group (39%) although this difference was not significant (p=0.08). Listening to Baby Shark prior to undertaking simulated CPR does not improve overall performance, but there is a potential tendency to improve adequate compression depth which may be beneficial in training exercises.

INTRODUCTION We observed that a number of patients presenting to our clinic with diverticular fistulation were taking nicorandil for angna. Recognised side effects of nicorandil include gastrointestinal and genital ulceration. The aim of our study was to determine whether nicorandil is an aetiological agent in diverticular fistulation. PATIENTS AND METHODS We conducted a case-control study of patients with diverticular disease related enteric fistulae. Two patient groups were identified: a study group of patients with diverticular fistulae, and a control group with uncomplicated diverticular disease. The proportion of patients who had ever used nicorandil was compared between the two groups. RESULTS A total of 153 case notes were analysed, 69 patients with fistulae and 84 control patients with uncomplicated diverticular disease. Female to male ratio in both groups was 2:1. The mean age was 71 years in the fistula group and 69 years in the control diverticular disease group (P = ns). Of those with colonic fistulae, 16% were taking nicorandil compared with 2% of the control group (odds ratio 7.8; 95% confidence interval 1.5–39.1; P = 0.008). There was no significant difference in rates of ischaemic heart disease between fistula and control groups. CONCLUSIONS Nicorandil is associated with fistula formation in diverticular disease.

Pictures use in an educational setting fits the idiom: old but gold. There have been plenty of studies revealing how good the use of pictures in the classrooms is. Pictures have been long known to have the ability to help motivate, demonstrate, and instruct the students during a learning process. This study is a sort of complement to the phenomenon as it focuses on researching the use of pictures in a classroom. Specifically, it aims at finding out the effectiveness of the use of picture cues in teaching writing.The study belongs to experimental research involving two groups of experiment and control. The eighth-grade students of a private junior high school in Central Java Indonesia are chosen as the subject of the research during 2017/2018 academic year. Employing a sample population technique, the study involves a total number of 56 students who are equally divided into 28 students as the experimental group and 28 students as the control group. The experimental group is taught using picture cues while the control group is taught without picture cues. Pre-test and post-test are used as techniques to collect the data. As for the data analysis technique, it’s done quantitatively applying both descriptive and inferential statistics.The result of the research shows that there is a significant difference in the students’ writing ability between those taught using picture cues and those who are not. This can be seen from the difference in the mean score between them. The result of the pre-test shows that at the beginning, both experimental and control groups have slightly different ability in writing with the mean scores 51.32 and 47.86 respectively. Meanwhile, the result of the post-test indicates an obvious difference between them in which the experimental group gains 65.75 as its mean score and the control group gets 59.14. Furthermore, the application of Independent t-test calculation results in a score of 0.000, which is lower than 0.05. This means that the use of picture cues is effective. Based on these results, it can be concluded that the use of picture cues is effective to teach writing to students.

Abstract Purpose: In our study, we aimed to determine the frequency of thyroid nodules in patients with acromegaly according to the American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) classification and its relationship with acromegaly disease activity. Methods: A total of 56 patients with acromegaly and age, sex, and body mass index matched with 56 healthy control subjects were included in our study. Thyroid-stimulating hormone, free thyroxine, and anti-thyroperoxidase antibody levels of patients and control subjects were measured. In addition, patients and healthy controls were evaluated by ultrasonography to determine thyroid structure, thyroid volume, and thyroid nodules and to make ACR TI-RADS classification. Results: Thyroid nodules were present in 31 (55.4%) of 56 patients in the acromegaly group and 20 (35.7%) of 56 subjects in the control group, and the frequency of thyroid nodules was significantly higher in the acromegaly group (p=0.038). The mean number of nodules in the acromegaly group and control group was 1.27±1.43 and 0.48±0.73, respectively, and the mean number of nodules was significantly higher in the acromegaly group (p=0.003). The number of patients with TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules in the acromegaly group was higher than the control group (p=0.026, p=0.049, p=0.007, respectively). No difference was found in terms of cytological findings between those who have undergone FNAB in the acromegaly group and control group. Conclusion: In our study, we found that the frequency of thyroid nodules, the number of thyroid nodules, and the number of TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules increased in patients with acromegaly. There was no significant difference between acromegaly disease activity and thyroid nodule frequency, number of thyroid nodules, and TI-RADS classifications.
