The aim of the present study was to evaluate the effects of uterine double flushing on embryo recovery rates (total structures and viable embryos), after a resting period with the uterus filled with PBS. There were 210 embryo recovery procedures conducted using the uterine double flushing method, and the results were compaired with 432 conventional single flushing procedures. All procedures were conducted with Limousin (n=403) and Guzerá (n=239) cows, following the same superovulation protocol. Cyclic donors received a progestagen implant (CIDR) and 1mL of oestradiol benzoate (Estrogin®) at Day 0. Between Day 5 and Day 9 animals received doses ranging from 200 to 300UI (zebu cows) and 300 to 500UI (taurine cows) of FSH (Pluset® – Serono) in decreasing doses. Between Day 6 and Day 8 PGF2a (Ciosin®) was administered, followed by withdrawal of the progestagen after 24h. Artificial insemination was performed between 14 and 26h after the beginning of treatment. For the double flushing procedure, after the first uterine flushing of both horns with 1L DPBS (Nutricell), a Foley catheter was positioned in the uterine body in order to fill the uterus with the same solution (80 to 150mL). After this procedure the catheter was closed with a disposable 5-mL syringe gasket, and the animals were allowed to rest in the surroundings of the work place for 30min. After this period, a second flush was performed in order to recover the remaning liquid used during manipulation of the uterus. Animals from the control group (group A) were subjected to a single uterine flushing procedure. From 210 double flushing procedures (group B – test), 1409 viable embryos were produced, classified as grades I, II, III and IV (IETS), (average of 6.7 embryos per procedure), whereas, in the 432 single flushing procedure (group A – control), 1993 embryos were produced (average of 4.6). Statistical analysis showed the increase of viable embryo recovery rate. When consecutive double flushing was performed, the average of recovered embryos increased from 8.3 to 12.7 (P<0.05) in Limousin cows, and from 7.9 to 11.5 (P<0.05) in Guzerá cows. Comparing recovery after single flushing with that after double flushing, the mean number of viable embryos increased from 4.7 to 6.9 (P<0.05) in Limousin cows and from 4.5 to 6.4 (P<0.05) in Guzerá cows. In order to assure the nonexistence of negligence effects or operator influence on results, the mean values of total embryo recovery rate after single flushing (control group) was compared to the mean values of the same rate after the first uterine flushing on test group. Results indicated no difference between recovery rates. The present work showed the viability of using the uterine double flushing procedure for improvement of embryo recovery rates in cattle.

Athletic mares are commonly utilized in an embryo transfer regimen during the breeding season, which allows owners to continue to train and compete with these animals. Exercising mares in a hot and humid environment has proven detrimental to embryo recovery rates. However, the effects of exercise under milder temperatures have not been examined. Our goal was to compare embryo recovery rates and embryo quality scores of mares under mild environmental conditions of 2 differing exercise regimens v. a single control group (n = 5). One treatment group (full exercise) consisted of mares (n = 5) exercised 6 days a week throughout the duration of the project. The partial-exercise group (n = 5) was exercised throughout the duration of the project 7 days a week, with full rest from day of detected ovulation to the proceeding embryo collection attempt. This was to limit any deleterious effects exercise may potentially have on the mare and subsequent early developing equine embryo. Exercise resumed the day after an embryo collection attempt for the partial-exercise group. Exercised mares were given a 1-month training period prior to the beginning of this project and were moderately exercised for 30 min in a mechanical exercise pen (free exerciser). Control mares were managed similarly as the other groups, however were not exercised. Mares were bred via artificial insemination and embryos were nonsurgically collected 7 d post-ovulation. Mean environmental temperature during the duration of this study was 27.1°C with average 60% humidity. Immediately following completion of exercise, mares in the full exercise group had a mean temperature increase of 1.0°C and partial-exercised mares increased 0.9°C. Exercise had a significant effect on embryo quality (P < 0.05, Table 1) but did not influence embryo recovery rate. The mean embryo quality score for the control group was 1.1, whereas the full-exercised group was 1.85 and partial-exercised group was 2.5. It appears from these data that exercise has a negative effect on embryo quality, thus lowering the availability of transferable embryos. Embryos of lower quality (≥3) have been shown to result in poor pregnancy rates in horses. Additionally, rest from ovulation to an embryo collection attempt did not improve embryo quality.

The hematological features of Gongronema latifolium, aqueous leaves extract was evaluated using standard methods. After 10 days of consecutive infusions into 9 experimental animals (rabbits). The rabbits were monitored and the following parameters determined; hemoglobin (HB), PCV, Platelet, WBC, Differential White Blood Cell. The Rabbits were grouped into 4, one consisting of control (group A), group B was fed with 0.5 mg/kg, group C with 1.0 mg/kg, and Group D with 1.5mg/kg of the aqueous extract of Gongronemalatifolium. The mean values obtained for hemoglobin estimation for the control group is 5.9 ± 4.1 g/dl, 9.1 ± 2.9 g/dl for group B 10.2 ± 1.8 g/dl for group C and 12.8 ± 0.1 g/dl for group D with no significant increase on the PCV estimation, the mean value for the control (group A) is 17.7 ± 12.3%, 27.3 ± 8.7% for group B, group C (30.6 ± 5.4%) and D (28.4 ± 0.3) show increase that statistically significant (p > 0.01). the platelet counts of group C (600 ± 0 x 109/L) and D(600 ± 0 x 109/L) show significant increase (p > 0.01) when compared with the control (600 ± 00). But the platelet value of group B (550 ± 50 x 109/L) shows no difference. No significant changes were observed in the White Blood Counts of the test groups B (3.5 ± 0.5 x 109/L), C (1.9 + 2.1 x 109/L) and D(3.6 ± 0.4) when compared with the control group (2.9 ± 1.9). The values obtained from the differential White Blood Counts (Neutrophils, Lymphocytes, Eosinophils and Monocytes) were not significant. Therefore, Gongronemalatifolium, when properly taken as a nutritional diet, causes beneficial changes on hemoglobin, packed cell volumes and platelet counts of consumers.

Background: There are few biomarkers that can be easily accessed in clinical settings and may reflect refractory Th2-eosinophlic inflammation and remodeling of the asthmatic airways. Serum periostin may be one such biomarker to aid our understanding of the patho-bio-physiology of asthma and exercise induced asthma. The aim of the study is to explore the relationship between serum periostin level and exercise induced bronchoconstriction in asthmatic children. Materials and Methods: This cross-sectional study was carried out on (90) children both sexes aged from 6 to 15 years including, (60) children with bronchial asthma and (30) children were enrolled as control group in the period from January 2018 to January 2019. Patients were randomly classified into two groups: I) Patient group: divided into 2 groups according to standardized treadmill exercise challenge test: Group A: (30) asthmatic children with positive test. Group B: (30) asthmatic children with negative test. II-Control group: (30) children apparently healthy with no personal or family history of asthma. All children were subjected to the following Investigations: Chest x-ray, pulmonary functions tests (FEV1 & PEFR) except controls, Laboratory investigations as CBC and Serum periostin level. Results: The mean values of both the percentage of PEFR and FEV1 after exercise in group A were significantly lower than those in group B and the percentage of PEFR and FEV1 after exercise in each group were significantly lower than the percentage before exercise in the same group. The mean value of eosinophilic count in group A was significantly higher than (group B and control group) and the mean value of eosinophilic count in group B was significantly higher than control group. The mean value of serum level of periostin in group A was significantly higher than (group B and control group), however, there was no significant difference between group B and control group as regard to serum level of periostin. Chest tightness, cough and wheezes after exercise and eosinophilic count in patients with high serum periostin level were significantly higher than patients with low serum periostin level, and both PEFR and FEV1 after exercise in patients with high serum periostin level were significantly lower than patients with low serum periostin level. Also the normal serum periostin levels vary among different age groups. Conclusion: Serum periostin level can be considered as a useful biomarker for diagnosis of Exercise induced bronchospasm (EIB) in asthmatic children especially when lung function test cannot be done However, cautious is required in evaluating serum periostin levels in children because it varies with age.

Abstract Introduction: Massage can be defined as the rhythmic and smooth manipulation of body tissues, with the aim to promote health and well-being. Objective: To assess the influence of classic massage on cardiac autonomic modulation. Methods: Cross-sectional study that evaluated healthy participants, with mean age between 18 and 25 years, divided into two groups: test group (TG, n=11) and control group (CG, n=10). The TG had their heartbeat recorded for 5min before receiving a classic massage for 40min and during three periods after this procedure: 0-5min, 5-10min and 10-15min. The CG had their heartbeats recorded at the same time; without receive massage. Cardiac autonomic modulation was investigated by heart rate variability (HRV). Results: The mean values of HRV rates were: pNN50, respectively, for the TG: before massage (10.5 ± 9.5%), and after massage: 0-5min (11.6 ± 7.2%), 5-10min (12.1 ± 8.0%) and 10-15min (11.1 ± 7.9%), with no significant statistical difference. The same result was found for the mean values of rMSSD index of the TG; before massage: 52.1 ± 46.2 ms, and after massage: 0-5min (50.0 ± 21.6ms), 5-10min (52.0 ± 27.4 ms) and 10-15min (48.2 ± 21.1 ms). Also, the values of LFnuand HFnu indexes did not change significantly before and after massage, and they were not statistically different from the values presented by the control group. Conclusion: The study results suggest that one session of classic massage does not modify cardiac autonomic modulation in healthy young adults.

The aim is to compare the use of Cyanoacrylate adhesives (CAA) to the conventional suturing technique in terms of free gingival grafts (FGG) stability and healing in lower anterior and premolar regions. A split mouth design was initiated on 22 participants. Each side (from 2nd premolar to central incisor) was randomized to either the control or test groups. In the control group, sutures were used to stabilize the FGG, while, in the test group, the FGG was stabilized with butyl-cyanoacrylate. Full-periodontal clinical parameters were employed to assess the periodontal health. FGG-related parameters assessed included the keratinized tissue width (KTW), gingival tissue thickness (GTT), FGG shrinkage% and pain using the VAS score. No significant differences in the mean values of the KTW nor FGG shrinkage% across six time points (p < 0.05) were observed, whereas highly significant differences in the mean values of GTT across six time points (F = 3.32; p = 0.008) were observed. The use of CAA in FGG stability and healing is comparable to conventional suturing for soft tissue grafts in terms of success outcomes. With its cost effectiveness, lesser time consumption, post-operative pain and comparable graft stability and dimensions, the use of CAA may be a promising alternative for conventional and microsurgical techniques for the stabilization of FGG in the oral cavity.

Visceral leishmaniasis (VL) is a cosmopolitan parasitic zoonosis that can promote myocarditis and heart rate changes in canine and human hosts. Thus, histopathological aspects of the myocardium and clinical, hematological, biochemical, radiological and electrocardiographic data were evaluated in a group of 36 dogs naturally infected with VL (VLG) and compared to data from 15 non-infected dogs (CG=Control Group). A prevalence of asymptomatic dogs was present in the CG (100%) and polysymptomatic dogs in the VLG (66%). In addition, two dogs in the VLG demonstrated systolic murmurs in the mitral valve region: one with a II/VI intensity and the other with a III/VI intensity. The mean values of RBC, hemoglobin and hematocrit were lower in dogs in VLG and were associated with higher values of total protein, total leukocytes, neutrophils, creatine kinase overall (CK) and the CK-MB fraction (CK-MB). The absence of radiographic changes was accompanied by a predominance of respiratory sinus arrhythmia associated with episodes of migratory pacemaker and sinus arrest in dogs in VLG (75%), sinus rhythm in dogs in CG (60%) and decreased P wave amplitude in VLG electrocardiography. Mononuclear cell infiltration was detected in the myocardium of 77,8% of dogs in GVL and classified primarily as mild multifocal lymphohistioplasmacytic. Amastigotes were detected in only one dog, which did not allow the association between myocarditis and parasitism, although the myocardial lesions that were found constitute irrefutable evidence of myocarditis in the VLG dogs, accompanied by lenient electrocardiographic changes compared to CG.

The purpose of this randomized controlled trial was to compare the immediate-loading protocol, in single restorations in the esthetic zone, by comparing the digital workflow in a test group (TG) vs. the analogical workflow in a control group (CG). A total of 50 patients were enrolled, requiring single hopeless tooth extraction. Twenty-five patients (TG) were randomly assigned to the immediate-loading protocol using the digital workflow, and twenty-five patients (CG) were assigned to the conventional workflow. Clinical and radiographic parameters were evaluated at the time of implant insertion (baseline) and after 3, 6 and 12 months, respectively. A clinician blind to conditions measured the Pink Esthetic Score (PES), as well as patient satisfaction. At 12-month follow-up, a cumulative survival rate of 100% was reported for all implants. No failures or biological complications were observed. No statistically significant differences were detected in the mean values of marginal bone loss and PES between the TG (0.12 ± 0.66 mm for MBL, 7.75 ± 0.89 for PES) and the CG (0.15 ± 0.54 mm for MBL, 7.50 ± 0.89 for PES). In 11 cases of TG, and 10 cases of CG, a one-year follow-up period showed an increased marginal bone level. No statistically significant differences were found in the mean total PES between test (7.75 ± 0.89) and control (7.5 ± 0.81) conditions. Furthermore, a customer satisfaction survey showed that patients preferred the digital workflow over the conventional workflow procedure (97.6 ± 4.3 vs. 69.2 ± 13.8). Digital workflow was more time-efficient than conventional workflow (97.2 ± 7.3 vs. 81.2 ± 11.3). Within the limitations of this study, no statistically significant differences were found between digital and traditional workflow.

ABSTRACT Objective:  To elucidate the mesiodistal inclination of the unerupted mandibular second premolar (MnP2) in cases of mandibular incisor (MnIc) agenesis and unilateral MnP2 agenesis. Materials and Methods:  Twenty-two cases of unilateral MnP2 agenesis (MnP2 agenesis group) and a control group (control group A) of 22 cases without permanent tooth agenesis excluding third molars were selected. Thirty-six cases of MnIc agenesis (MnIc agenesis group) and another control group (control group B) of 36 subjects were also selected. Mesiodistal inclination of the unerupted MnP2 on the panoramic X-rays was measured according to the distal angle and premolar-molar angle using the methods of Shalish et al. and Baccetti et al., respectively. Differences in mean values of the angular measurements between agenesis groups and corresponding controls were investigated (unpaired t-test). Results:  In the MnP2 agenesis group, the mean distal angle decreased 12.3° and the mean premolar-molar angle increased 13.3° for the MnP2 compared with control group A (both P &lt; .001). In the MnIc agenesis group, no significant differences in the means of those angles for the MnP2 were found when compared with control group B. Conclusion:  In Japanese orthodontic patients, there is a relationship between unilateral MnP2 agenesis and the mesiodistal angulation of the unerupted MnP2. However, no significant relationship was observed between MnIc agenesis (which relationship is often seen in Asian populations) and the position of the unerupted MnP2. These results suggest that different genetic factors are involved in MnP2 agenesis and MnIc agenesis.
