#1
Yang Meng, De-Gang Sun
This article presented a case of discovering and diagnosing three roots with four canals of the maxillary first premolar. We found and located the extra root canal by clinical diagnosis, careful observation during the operation, and multiangle X-ray. We further confirmed the existence of the three roots with four canals with the help of cone-beam computed tomography. Finally, we verified the success of the high-quality root-canal therapy through root optical microscopy.

This case report focused on a patient with supraeruption of the first and second mandibular molars as a result of loss of the first and second maxillary molars for a long time. We adopted a combination of a vacuum-formed removable appliance and elastics to intrude the first and second mandibular molars by using a continuous, light force to acquire sufficient restoration space for maxillary molars. Thus, the dental-implant treatment was successful, and a good and stable occlusal relationship was established.

Seed germination is the earliest trait expressed in a plant's life history, and it can directly affect the expression of post germination traits. Plant height is central to plant ecological strategies, because it is a major determinant of the ability of a species to compete for light. Thus, linking seed germination and plant height at the community level is very important to understanding plant fitness and community structure. Here, we tested storage condition and temperature requirements for germination of 31 species from a wetland plant community on the eastern Tibet Plateau, and analyzed correlation of germination traits with plant height in relation to storage condition...

INTRODUCTION: When a sufficiently high-quality liver is available, classic liver graft splitting is performed. In such cases, a small child receives the left-lateral split graft, with subsequent transplantation of the right-extended graft in an adult. METHODS: We analysed 64 patients who received right-extended liver grafts from 2007-2015, and compared outcomes between cases of external versus in-house graft splitting. RESULTS: We found excellent donor data and comparable recipient characteristics...

Large-scale restoration programs in the tropics require large volumes of high quality, genetically diverse and locally adapted seeds from large number of species. However, scarcity of native seeds is a critical restriction to achieve restoration targets. In this paper, we analyze three successful community-based networks that supply native seeds and seedlings for Brazilian Amazon and Cerrado restoration projects. In addition, we propose directions to promote local participation, legal, technical and commercialization issues for upscaling the market of native seeds for restoration with high quality and social justice...

AIMS: The pathogenesis of dermatophytoses is associated with the secretion of enzymes degrading the infected tissue components. Although many studies on enzymatic activity of dermatophytes have been conducted over the years, there have been no concrete proposals on construction of the profile of enzymes characteristic of individual species, genus, or ecological types of dermatophytes. The aim of this study was to assess the capability of clinical dermatophyte isolates from both symptomatic and asymptomatic animals and humans to produce different enzymes...

Fully covered self-expandable metal stents (FCSEMS) have been used for the treatment of benign esophageal conditions such as perforation, leaks, and strictures [1]; high clinical success is reported [2]. Different anchoring methods have been described (clips, suturing devices, over-the-scope clips and Shim technique [2]), because of high migration rates (4-36%) [3,4]. However, not all cases are candidates, mostly in "difficult" cases where enteral feeding is needed [5]. We report the use of the nasojejunal-stent technique (NJST) to prevent migration of FCSEMS in three difficult cases...

BACKGROUND: Clonal naevi are characterized by a focal proliferation of pigmented melanocytes in an otherwise banal naevus. These subclones are often composed of aggregates of larger, epithelioid melanocytes with nuclear atypia and dusty-grey cytoplasmic pigmentation, which are referred to as 'pulverocytes', and this finding may lead to a misdiagnosis of malignant melanoma (MM). AIM: To characterize the significance of subclones of dusty-grey pigmented epithelioid melanocytes within spitzoid neoplasms...

Recurrence and second primary cancer (SPC) continue to represent major obstacles to long-term survival in head and neck cancer (HNC). Our aim was to evaluate whether established demographics, lifestyle-related risk factors for HNC and clinical data are associated with recurrence and SPC in HNC. We conducted a multicentre study by using data from five studies members of the International Head and Neck Cancer Epidemiology consortium-Milan, Rome, Western Europe, Sao Paulo, and Japan, totalling 4005 HNC cases with a median age of 59 (interquartile range 52-67)...

REVIEW
Leam A Craig, Martin Rettenberger
PURPOSE OF REVIEW: Case formulations (CF) have been the cornerstone of effective practice in clinical psychology since the 1950s and now form one of the core competencies in clinical and forensic assessment. The use of CFs within forensic settings is becoming more relevant when working with offenders who have experienced significant trauma, suffered from personality disorder, and have displayed sexually abusive behavior. Furthermore, most North American and European jurisdictions insist that expert witnesses adopt an idiosyncratic approach to risk assessment and consider the characteristics of the individual as part of a wider formulation of the problem behavior...

Adam Stenman, Jan Zedenius, Carl Christofer Juhlin
PURPOSE: Pheochromocytomas (PCCs) exhibit malignant potential, but current histological modalities for the proper detection of aggressive behavior are debated. The two most widespread algorithms are the "Pheochromocytoma of the Adrenal Gland Scaled Score" (PASS) and the "Grading System for Adrenal Pheochromocytoma and Paraganglioma" (GAPP), both which mostly rely on histological parameters to identify PCC patients at risk of disseminated disease. Since the algorithms are derived from studies using predominantly sporadic PCCs, little is known whether the PASS or GAPP scores can predict malignant potential in hereditary cases...
