Aim: To evaluate the effect of Tri-staple™ technology and slow firing using the Endo-GIA™ endoscopic linear stapler. Methods: The cardiac and pyloric portions of porcine stomachs were divided using the endoscopic linear stapler with different reload types. A total of 8 min of waiting time was employed during firing in the slow-firing group and no waiting time was employed in the normal-firing group. The shape of the staples was then evaluated. The length of the staple line and serosal laceration was also determined. Results: There was a moderate negative correlation between tissue thickness and secure staple formation. Tri-staple™ reloads (purple, black) offered more secure staple formation compared with Universal green reload. Although slow firing enhanced secure staple formation, its effect was greater when using green reload, compared with Tri-staple™ reloads. Significantly shorter staple line length and longer serosal laceration was observed in the thick tissue. Although the cartridge type did not influence lengths of the staple line or serosal laceration, both were better in the slow-firing group. Conclusions: Tri-staple™ reloads offered more secure staple formation compared with the Universal reload. Although slow firing improved staple line shortening and serosal laceration, its effect on secure stapling was relatively small when using Tri-staple™ reloads.

BACKGROUND: Forward head posture (FHP) is the most common malposition in the head and neck area. With the growing use of digital devices, the prevalence of FHP may be expected to increase dramatically. Thus far, FHP has been evaluated only in the sagittal plane. OBJECTIVE: The objective of this study was to measure angles and indices from anatomical landmarks in the frontal plane and determine the possible correlations between these variables and craniovertebral angle (CVA) as an index of FHP in the sagittal plane. METHODS: Fifty eight healthy individuals (29 men, 29 women) between 18 and 40 years old participated in this cross-sectional study. Participants were evaluated with an 8-camera motion analysis system. After markers were placed on predetermined landmarks, the participants were asked to maintain their head and neck in the neutral position for 5 seconds. Then participants induced FHP by flexing and lowering their head. The correlation between CVA and a set of angles and indices was calculated at the moment of FHP induction. RESULTS: A moderate correlation was observed between 3-D CVA and the angle formed between the sternum and both tragi for the whole sample and separately in both sexes. A moderate negative correlation was observed between 3-D CVA and height, weight, and BMI in women. A moderate negative correlation was observed between 3-D CVA and height, weight, BMI, and hours on digital devices in men. CONCLUSIONS: Changes in CVA in the sagittal plane can be predicted from changes in the angle formed between the midpoint of the sternum and the left and right tragi in the frontal plane.

Abstract Background Implantoplasty is an option in peri-implantitis treatment, but little is known about the effect on the soft tissue. The aim of the study was to characterize surface roughness following experimental implantoplasty and to examine its effect on human fibroblast growth and the secretion of selected proteins.Methods Titanium grade IV coins were mechanically treated with six different rotating bur sequences; diamond burs or carbide burs alone, or followed by either Arkansas stone bur or silicone burs. Machined and rough-surface sandblasted, acid-etched (SLA) coins were used as control. The surface topography was characterized by scanning electron microscope and profilometer. Human gingival fibroblasts from two donors were cultured on the coins to quantify the effect on cell morphology, growth and protein secretion by confocal microscopy and multiplex immunoassay.Results All surface roughness parameters were lower for the surfaces treated with experimental implantoplasty than for the SLA surface, and the sequence of carbide burs followed by silicone burs rendered the least rough surface of the test groups. The implantoplasty procedures changed the elemental composition of the titanium surface. High surface roughness showed a weak to moderate negative correlation to fibroblast growth, but induced a higher secretion of VEGF, IL-6 and MCP-3 to the cell medium compared to the least rough surfaces of the test groups. At day 30 fibronectin levels were higher in the SLA group.Conclusions The surface roughness following implantoplasty demonstrated a weak to moderate negative correlation with the growth of fibroblasts. The addition of Arkansas stone and silicon burs to the experimental implantoplasty bur protocol rendered an initial increase in fibroblast growth. Implantoplasty altered the elemental composition of the titanium surface, and had an effect on the fibroblast cytokine secretion and fibronectin levels.

Статья посвящена исследованию влияния вторичных образов различного типа на перевод художественного текста. Результаты эксперимента подтверждают ведущую роль предметных образов для нахождения адекватных решений. Также показано наличие умеренной обратной корреляции между уровнем образного мышления в целом и количеством неадекватных трансформаций в переводе. Выявлено негативное влияние на результаты перевода низкого пространственного воображения. The article aims to investigate the influence of different types of secondary mental images on literary text translation. Our experimental data confirm a stone role of object imagery for finding adequate translation solutions, as well as suggest a moderate negative correlation between individual imagery scores and the number of inadequate translation solutions. A low level of spatial imagery may negatively affect the translator’s choices.

Abstract Background A Killian–Jamieson diverticulum is a rare pharyngoesophageal diverticulum that is radically treated by diverticulectomy. However, there is no consensus on whether cricopharyngeal myotomy is necessary, and the optimal surgical methods that prevent postoperative complications such as leakage are undetermined. Case presentation A 49-year-old man was referred to our hospital with oropharyngeal dysphagia while eating. The patient was preoperatively diagnosed with a Killian–Jamieson diverticulum based on radiographic and clinical findings and underwent a transcervical diverticulectomy. The recurrent laryngeal nerves were preserved using an intraoperative nerve monitoring system, and the diverticulum was identified without difficulty. A partial cricopharyngeal myotomy was performed to expose the base of the diverticulum. The diverticulum was transected transversally using a linear stapler under the guidance of intraoperative upper intestinal endoscopy. A thyroid gland flap supplied by the superior thyroid artery was harvested and placed overlapping the area of the partial cricopharyngeal myotomy. Due to the proximity of the recurrent laryngeal nerve course to the diverticulum stump, the staple line was not buried with sutures. The thyroid gland flap with its rich vascular supply was fixed to completely cover the staple line on the cut surface of the thyroid gland. The postoperative course was uneventful, without vocal cord paralysis. The patient was discharged on postoperative day 8. He developed no clinical signs suggesting leakage, recurrence, or adverse events. Conclusion Killian–Jamieson diverticulectomy using a thyroid gland flap and partial cricopharyngeal myotomy is a valid treatment option that may prevent complications and recurrence. Precise evaluation of the diverticulum using an intraoperative nerve monitoring system is crucial for the repair.

To assess tactical changes, we compared team performance indicators between the 2015 and 2007 Cricket World Cup Tournaments. Specifically, we determined magnitudes of differences between winning and losing teams and compared round robin and the knockout or Super 8 phases. Magnitude of difference between teams was established with a standardised (Cohen's) effect size with 90% confidence limits. Taking wickets and having a high batting run rate consistently had large to very large effect sizes across both rounds of both tournaments. A higher percentage of runs in singles had a small to moderate negative correlation with winning across both tournaments (ranging from effect size = −0.28 ± 0.07 to −1.18 ± 0.79 90% CL). The main contribution of this paper is that across eight years and across different geographical locations, key performance indicators had similar magnitudes in 50-over World Cup Cricket. Coaches can be confident in the relevant importance of different performance indicators.
