Accurate estrus detection is an essential component of a successful AI program in modern swine operations. It is necessary to establish efficacious means of estrus detection and optimize reproductive performance in the herd. Measurement of physiological traits such as body temperature, vaginal electrical resistance, and vulva reddening have been investigated as methods to aid in estrus detection in swine. The relationship between vulvar skin temperature (VST) and ovulation has not been previously investigated. Therefore, the objective of this study was to assess changes in VST that occur during the periovulatory period using digital infrared thermography (IRT). The experiment group consisted of a total of 25 gilts and 27 multiparous sows, and the control group consisted of 30 sows that were 60 days of gestation. All Yorkshire-Landrace females were housed individually in a temperature and humidity controlled environment. VST were measured twice daily at 8-h intervals using the infrared digital thermocamera (Fluke IR FlexCam® Thermal Imager, Fluke Corporation, Everett, WA) while the animals were standing and eating prior to estrus detection. Estrus detection was performed twice daily (at 8-h intervals) with the aid of an adult boar. Once standing estrus was observed, transrectal real-time ultrasound was performed twice daily at 8-h intervals to monitor follicle development and determine the time of ovulation. Ovaries were visualized using an Aloka 500 V ultrasonics machine (Aloka Inc., Tokyo, Japan) fitted with a transrectal 7.5-MHz linear transducer, which was fitted into a rigid, fixed-angle PVC adapter. Average VST and hours were reported in mean ± SEM and compared using an ANOVA and Student’s t-test using SAS software (SAS Institute Inc., Cary, NC, USA). Additionally, pairwise comparisons were performed to compare VST at different times during estrus. Significant differences were reported at P ≤ 0.05. Evidence of CL formation and ovulation was detected at 38 ± 9.3 h after onset of estrus in gilts, and 43 ± 12 h in sows. The mean VST of sows during estrus was significantly higher (P ≤ 0.05) than that of gilts. During estrus, the mean VST of gilts reached a peak of 35.6 ± 0.24°C and then decreased significantly to 33.9 ± 0.32°C 12 h prior to ovulation. This marked change in mean VST was detected between 36 and 12 h prior to ovulation. There was a similar trend in sows with a peak mean VST of 36.1 ± 0.25°C at 24 h prior to ovulation and then dropping to 34.6 ± 0.31°C 12 h prior to ovulation. There was no significant difference (P ≥ 0.05) between VST in gilts and sows at the time of ovulation. This study demonstrated that VST of sows and gilts measured by IRT change significantly during the periovulatory period. Additionally, there are distinct times that VST rises and then falls precipitously in sows compared with gilts. Digital IRT as a predictor for ovulation in swine appears to be a promising tool. Further studies involving predictor models and hormonal assays need to be performed.

Abstract This study evaluated the use of the infrared thermography (IT) as a tool to identify the temperament of 75 non-castrated water buffaloes (390±32 days of age; 310±61.27 kg of initial body weight) of 3 genetic groups (GG:Jafarabadi, Mediterranean, and Murrah; n = 25 for each GG). The animals were classified for temperament through the temperament score (TSc) obtained by the mean of the sum of the scores of the time of entry into the squeeze chute (1 to 5: 1=greater time spent for entry; 5=less time spent for entry) and the exit velocity score (1 to 5: 1=lower speed; 5=higher speed) calculated after the period of adaptation to the feedlot (d0). The animals were categorized into adequate (ADQ; TSc≤3) or excitable (EXC; TSc >3) temperaments. The rectal temperature was measured and IT images were obtained (Testo 882 Thermal Imager, Testo, Inc, Germany) from regions of the chest, eye, snout, cheek, foreleg (left side), ribs, hind legs, rear area (left side), and scrotum on d0. Data were analyzed using MIXED procedure in SAS, considering the GG, temperament, and the resulting interaction as fixed effects. Correlation was analyzed using the CORR procedure of SAS. There were no effects of interactions (P ≥ 0.14). ADQ animals showed lower rectal (P = 0.02) and ribs (P = 0.05) temperatures than EXC animals (Table1). Tendencies for temperament effect were detected for chest (P = 0.06) and rear area (P = 0.07). There was no effect of temperament for other variables (P = 0.19). Positive correlations were verified between the TSc and rectal (r=0.36; P < 0.01), chest (r=0.35; P < 0.01), and rear area (r=0.33; P < 0.01) temperatures. Tendency for a positive correlation was detected between TSc and scrotum (r=0.23; P = 0.07). In conclusion, the temperament causes changes in the temperature of some body regions suggesting the IT technology may be a promising tool for assessing the temperament of water buffaloes.

Objective: Celiac disease can be associated with other diseases, including neurological disorders. In this study, the relationship between celiac disease and refractory epilepsy was evaluated in patients referred to Imam Khomeini Hospital of Urmia. Material & Methods: In this cross-sectional study, patients with refractory epilepsy referred to the neurology clinic of Imam Khomeini Hospital of Urmia, during the second half of 2019 and controlled epilepsy were studied as a control group. The statistical population of the present study included 50 patients with refractory seizures and 50 patients with controlled seizures. The mean age of patients was 32.96 ± 11.35 years. Five ml blood samples were taken from the patients, and a serum anti-tTG test was performed using the ELISA kit. Then, in patients with positive anti-tTG, a duodenal biopsy sample was prepared using an endoscopy. Results: This study showed that the mean serum level of anti-tTG in patients with refractory epilepsy was higher than in patients with controlled epilepsy. Anti-tTG test results were positive in five of fifty patients with refractory epilepsy, and it was positive in two of fifty patients with controlled epilepsy. There was no significant difference between the two groups in terms of serum levels anti-tTG (p=0.14). Also, there was no significant relationship between serum level anti-tTG, age and genus (p>0.05). Biopsy results in three patients in the refractory epilepsy group and one patient in the controlled epilepsy group was in favor of a definitive diagnosis of the celiac disease. Patients in whom the celiac disease was confirmed by endoscopy had higher anti-tTG levels (p=0.006). Conclusion: There was no significant difference between the celiac disease in the group with refractory epilepsy and controlled epilepsy.

Background: Improper estrus detection causes huge economic losses due to inaccurate time of insemination leading to poor conception rate. So, here pedometer proved to be a promising tool in defining optimal time of insemination,improving fertilization rates based on increased number of steps. The study is to determine the relationship between increased pedometer activity for efficient estrus alert and duration of estrus for prediction of accurate time of ovulation.Methods: Oestrus detected in KF cows (N = 20) by behavioural estrus visually. Further validated by pedometer activity and confirmed by progesterone (P4) and estradiol (E2) concentration. Individual animal daily activity pattern collected, transformed and arranged to in Excel sheet for statistical analysis for determining estrus alert, estrus duration, ovulation and insemination time.Result: Based on pedometer estrus alert,duration, estrus onset and estrus end to ovulation was 15.63±1.46 h, 30.53±1.21h and 14.89±2.03h respectively. The mean activity count per hour (ACPH) for the pedometer oestrus (426.19±70.19) and E2 found associated on oestrus day. Based on oestrus alert and duration artificial insemination (A.I) can be made 10h after onset up to 5h after end of pedometer oestrus. Pedometer detects estrus slightly earlier than behavioural estrus efficiently and help in predicting the ovulation time for governing the accurate time of insemination.

Background and Objective: The relationship between periodontal sensation and Myofascial Pain (MP) is not yet fully clarified. The aim of this study was to test the null hypothesis that there is no difference in the periodontal sensation threshold between subjects with MP and subjects with no Temporomandibular Disorders (TMD). Methods: Participants have clinically assessed in accordance with the Research Diagnostic Criteria for Temporomandibular Disorders version 1.0 guidelines and assigned to the MP group (mean age 54.8 ± 14.8 years; 1 male and 11 females) or the control group (mean age: 63.9 ± 13.2 years; 1 male and 15 females). The Passive Periodontal Sensation Threshold (PPST) was evaluated using impulsive mechanical stimulation on the occlusal surface parallel to the tooth axis of the maxillary first molar, if present. The difference in the mean PPST between the MP group and the control group was evaluated using the Student t-test after checking for homoscedasticity. Results: The mean PPST value was 1050.1 ± 480.3 mN in the MP group and 712.3 ± 288.5 mN in the control group. A significant difference was observed between these mean PPST values (p = 0.045). Conclusion: There was a significant difference in PPST between the MP group and the control group. Although the etiology of the change of PPST is still unknown, the higher PPST value observed in MP patients suggests that future study on occlusal dysesthesia or occlusal sensation-related pathosis is warranted.

Introduction: This study was aimed to determine the relationship between vitamin D and soluble vitamin D receptor (VDR) levels and brucellosis, a common infection in Turkey, in which the cellular immune system is important in the course of the disease. Methodology: Patients who had been followed up in the Department of Infectious Diseases and Clinical Microbiology of Cukurova University Medical Faculty, having been diagnosed with brucellosis and who had no brucellosis treatment before, were enrolled in the study along with healthy controls. The participants’ vitamin D and soluble VDR values were recorded. Laboratory parameters of patients and controls, clinical findings, and disease course of brucellosis patients were also noted. Results: The mean age of the 86 brucellosis patients, of whom 38 (44.2%) were males and 48 (55.8%) were females, was 40.9 ± 18.4 years. Complicated course of brucellosis rate was found to be 29.1%. Vitamin D and VDR levels were lower in brucellosis patients at the time of diagnosis compared to control group. For males, vitamin D and VDR levels were higher in the control group than in the patient group. In males, VDR levels were higher than in females. A significant difference was not found between clinical forms of the disease and vitamin D and VDR levels. Conclusions: Vitamin D and VDR levels were shown to be significantly lower in brucellosis patients before treatment compared to the control group. These results suggest that vitamin D could be involved in the pathogenesis of the disease.

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.

Purpose: To evaluate and compare corneal hysteresis (CH), corneal resistance factor (CRF), and central corneal thickness (CCT), measurements were taken between a healthy population (controls), patients diagnosed with glaucoma (DG), and glaucoma suspect patients due to ocular hypertension (OHT), family history of glaucoma (FHG), or glaucoma-like optic discs (GLD). Additionally, Goldmann-correlated intraocular pressure (IOPg) and corneal-compensated IOP (IOPcc) were compared between the different groups of patients. Methods: In this prospective analytical-observational study, a total of 1065 patients (one eye of each) were recruited to undergo Ocular Response Analyzer (ORA) testing, ultrasound pachymetry, and clinical examination. Corneal biomechanical parameters (CH, CRF), CCT, IOPg, and IOPcc were measured in the control group (n = 574) and the other groups: DG (n = 147), FHG (n = 78), GLD (n = 90), and OHT (n = 176). We performed a variance analysis (ANOVA) for all the dependent variables according to the different diagnostic categories with multiple comparisons to identify the differences between the diagnostic categories, deeming p < 0.05 as statistically significant. Results: The mean CH in the DG group (9.69 mmHg) was significantly lower compared to controls (10.75 mmHg; mean difference 1.05, p < 0.001), FHG (10.70 mmHg; mean difference 1.00, p < 0.05), GLD (10.63 mmHg; mean difference 0.93, p < 0.05) and OHT (10.54 mmHg; mean difference 0.84, p < 0.05). No glaucoma suspects (FHG, GLD, OHT groups) presented significant differences between themselves and the control group (p = 1.00). No statistically significant differences were found in the mean CRF between DG (11.18 mmHg) and the control group (10.75 mmHg; mean difference 0.42, p = 0.40). The FHG and OHT groups showed significantly higher mean CRF values (12.32 and 12.41 mmHg, respectively) than the DG group (11.18 mmHg), with mean differences of 1.13 (p < 0.05) and 1.22 (p < 0.001), respectively. No statistically significant differences were found in CCT in the analysis between DG (562 μ) and the other groups (control = 556 μ, FHG = 576 μ, GLD = 569 μ, OHT = 570 μ). The means of IOPg and IOPcc values were higher in the DG patient and suspect groups than in the control group, with statistically significant differences in all groups (p < 0.001). Conclusion: This study presents corneal biomechanical values (CH, CRF), CCT, IOPg, and IOPcc for diagnosed glaucoma patients, three suspected glaucoma groups, and a healthy population, using the ORA. Mean CH values were markedly lower in the DG group (diagnosed with glaucoma damage) compared to the other groups. No significant difference was found in CCT between the DG and control groups. Unexpectedly, CRF showed higher values in all groups than in the control group, but the difference was only statistically significant in the suspect groups (FHG, GLD, and OHT), not in the DG group.
