The apparent fiber density and complexity metric showed relatively minor differences when only q-space undersampling was used, but deteriorate when k-space undersampling was applied. Likewise, the tract density weighted image showed good results when only q-space undersampling was applied using 15 directions or more, but information was lost when fewer volumes or k-space undersampling were used.

It was found that acquiring 15 to 20 diffusion directions with a full k-space and reconstructed using compressed sensing could suffice for a replicable measurement of quantitative measures in mice, where areas near the sinuses and ear cavities are untainted by signal loss.

Reconstructing the occlusal morphology of posterior teeth in definitive dental prosthesis can be challenging.The use of the correlation technique enables replication of the information and occlusal anatomy of interim dental prostheses to the definitive ones. The purpose of this controlled clinical trial was to compare the static and dynamic contacts (SDC) of monolithic zirconia crowns designed with correlation and library techniques.

Twenty-four patients were included in the study for a total of 28molars. For each abutment tooth, an interim crown was fabricated and two digital scans, with and without the interim crown in place were made. Two single crowns were designed using correlation and library techniques. Fifty-six monolithic zirconia crowns were milled. The interim and definitive crowns were evaluated intraorally for SDC by using a 24-μm-thick blue articulating foil. After removing the interim and definite crowns, extraoral photographs were taken to calculate the SDC area using software (ImageJ) andThe average area of the SDC of monolithic zirconia crowns designed by using the correlation technique was similar to that of interim crowns. The library technique was less effective when replicating the SDC compared to the correlation technique.

The aim of the present study was to investigate emotional exhaustion, work engagement, and turnover intention in the nursing profession by exploring the antecedent effects of ethical leadership and job components such as decision authority.

Emotional exhaustion, low work engagement, and high turnover intention are prevalent issues in the nursing profession. The experience of feeling overworked has led to feelings of burnout and low morale among nurses in Ireland, which has prompted the authors to identify potential variables that reduce these outcomes-in this case, ethical leadership and decision authority.

A descriptive, cross-sectional survey design was used across three hospital sites.

A cross-sectional sample of 89 nurses was recruited from three Irish hospitals to capture the experience of nurses between December 2017 – February 2018. Hypotheses were tested using path model analysis.

Ethical leadership positively predicted decision authority among nurses. Ethical leadership also had an indirecte predictor of emotional exhaustion, and turnover intention among nurses.

To describe the clinical presentation and outcome of two greyhounds with calcaneal malunions that were treated with corrective osteotomy and partial tarsal arthrodesis.

Short case series.

Two adult racing greyhounds.

Varus and recurvatum deformity of the calcaneus was ascribed to malunion of prior calcaneal fracture with concomitant central bone fracture that had been sustained during racing in both dogs. Both dogs exhibited severe, weight-bearing lameness and had radiographic evidence of moderate to severe osteoarthritis of the proximal intertarsal joint. A closing wedge corrective osteotomy and partial tarsal arthrodesis were performed with a 2.7-mm locking compression plate and cancellous autograft.

Calcaneal morphology and alignment of the common calcaneal tendon seemed restored postoperatively. The implant was removed in one dog, while the other dog experienced no postoperative complications. Lameness improved in both dogs, although residual intermittent lameness after heavy exercise was reported by owners of both dogs 1 year after surgery. Overall, owner satisfaction and outcome were considered good-to-excellent in both dogs.

Corrective osteotomy and partial tarsal arthrodesis for treatment of malunited calcaneal fractures may be considered in dogs with clinical signs related to calcaneal malunion.

Corrective osteotomy and partial tarsal arthrodesis for treatment of malunited calcaneal fractures may be considered in dogs with clinical signs related to calcaneal malunion.The myocardial bridge (MB) is an anomaly that the myocardial fibres cover on a segment of the subepicardial coronary arteries or their branches in domestic animals and humans. The aim of the present study was to determine the relationships between the characteristics of the MB and ramus interventricularis paraconalis at three levels in lambs and adult sheep. Thirty-three hearts (16 lambs and 17 sheep) were used to determine the MB (length, angle and thickness) and vessel (vessel diameter and thicknesses of tunica intima et media of ramus interventricularis paraconalis) characteristics. Independent-samples t test was applied to compare variables between lambs and sheep. MTX-211 inhibitor Spearman’s correlation analysis was conducted to evaluate the relationships between bridge and vessel characteristics at three bridge levels. Length, angle and thickness of myocardial bridges were not significantly different between the lambs and sheep (p > .05). The mean length, angle and thickness were 24.9 ± 16.1 mm, 113.7 ± 11.2° and 1,098 ± 555 µm in 33 hearts, respectively. In lambs, the mean vessel diameters were 1,930 ± 742 µm (1,534-2,325 µm), 1,247 ± 665 µm (893-1,601 µm) and 865 ± 172 µm (774-957 µm) at the pre-bridge, bridge and post-bridge levels, respectively. In sheep, the mean vessel diameters in the same order were 1,861 ± 1,068 µm, 1,337 ± 308 µm and 1,287 ± 549 µm. The bridge prevalence was 100% in the samples examined. In conclusion, coronary arterial diseases related to myocardial bridge should not be expected in sheep for veterinary cardiology practice. It may also be concluded that the cross-breeds of the Awassi and Chios sheep may be useful in experimental studies related to myocardial bridge surgery.
