The induced membrane technique for reconstruction of bone defects has proved its effectiveness and is now widely accepted. The 2 stages procedure, implying a cement spacer in the first stage and a huge bone graft in the second stage, responds to rigorous technical details involving each phase of the procedure. Prerequisites for the technique, cement spacer, bone fixation, time between the 2 stages, grafting, and postoperative course are reported and discussed.

Rod J Rohrich, Min-Jeong Cho
Minimizing blood loss during surgery is critical, and many modalities have been used to decrease unwanted surgical bleeding. Among many methods, use of pharmacological agents such as anti-fibrinolytic drugs have been shown to significantly reduce blood loss and the rates of postoperative blood transfusion in many literatures. Tranexamic acid is an anti-fibrinolytic agent that has been widely used in other surgical specialties, especially in cardiac, orthopedic, and trauma surgery . Despite its known benefits, the use of tranexamic acid in plastic surgery is extremely limited, primarily because most plastic surgery procedures do not involve the extent of blood loss that can lead to anemia and the need for blood transfusion, as is common in major orthopedic and cardiac surgery procedures...

In vivo magnetic resonance spectroscopy provides insight into metabolism in the human body. New acquisition protocols are often proposed to improve the quality or efficiency of data collection. Processing pipelines must also be developed to use these data optimally. Current fitting software is either targeted at general spectroscopy fitting, or for specific protocols. We therefore introduce the MATLAB-based OXford Spectroscopy Analysis (OXSA) toolbox to allow researchers to rapidly develop their own customised processing pipelines...

Various corneal diseases, such as hereditary corneal dystrophies, corneal infection, and bullous keratopathy, cause corneal opacity, scarring, and edema, leading to severely decreased visual acuity and loss of vision. These diseases were regarded as corneal opacity diseases, and the decreased visual acuity was considered to be predominantly caused by corneal opacity. The influence of corneal irregular astigmatism on vision has been poorly understood to date, mainly because accurate quantification of irregular astigmatism has been technically challenging...

Diagnostic classification systems in psychiatry have continued to rely on clinical phenomenology, despite limitations inherent in that approach. In view of these limitations and recent progress in neuroscience, the National Institute of Mental Health (NIMH) has initiated the Research Domain Criteria (RDoC) project to develop a more neuroscientifically based system of characterizing and classifying psychiatric disorders. The RDoC initiative aims to transform psychiatry into an integrative science of psychopathology in which mental illnesses will be defined as involving putative dysfunctions in neural nodes and networks...

REVIEW
Periklis Dousdampanis, Kostantina Trigka
Renal osteodystrophy (ROD) is not a uniform bone disease; it is a heterogeneous group of metabolic bone diseases due to chronic kidney disease (CKD). The traditional term of ROD does not accurately include the wide spectrum of "CKD-mineral and bone disorder" (CKD-MBD) and has been restricted to define the several specific histologic disturbances of bone disease associated with CKD. Circulating parathyroid hormone (PTH) and total alkaline phosphatase levels do not always reflect bone turnover in CKD-MBD, whereas bone biopsy provides precise information regarding bone pathology...

BACKGROUND/AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is typically performed in prone position. In cases of difficulty in prone position, ERCP can be performed in left lateral position. We aimed to evaluate the efficacy and safety of left lateral position for ERCP compared with those of prone position. PATIENTS AND METHODS: Between August 2015 and March 2016, a total of 62 patients with native papilla who underwent ERCP were randomly assigned to undergo the procedure in left lateral position (n = 31) or prone position (n = 31)...

Controlled sustained-release preparation (CSRP) is a definitely important source of innovative medicines, however, its further researches and development are limited due to the complexity of Chinese medicine (CM) compositions, and a series of unclear key problems like the apparent properties from physical and chemical aspects. Combined with the CM characteristics of the multiple components and synergistic effect, a series of bottleneck problems in the preparation of CSRP were analyzed. Then the mechanism and influences of supermolecular chemical theory in the CSRP about the multiple-components overall-control were explored under the guideline of "overall control, synchronous dissolution" in CSRP, based on the previous explications about supramolecular chemistry theories and with the application of single component precision controlling technologies...

Shanxi, a traditional production area to produce genuine Astragali Radix of high quality, has experienced major changes in the pattern of resources. This area once accounted for half of Astragali Radix industry, but now only serves as the largest supply area of traditional wild Astragali Radix. Furthermore, the strategic position of Shanxi Astragali Radix industry will become more prominent and more important to economic and social development in face of the diversity of market demands, especially for the strong demands of high-end Astragali Radix...

Recently, there has been an upsurge of attention focused on bias and its impact on specialized artificial intelligence (AI) applications. Allegations of racism and sexism have permeated the conversation as stories surface about search engines delivering job postings for well-paying technical jobs to men and not women, or providing arrest mugshots when keywords such as "black teenagers" are entered. Learning algorithms are evolving; they are often created from parsing through large datasets of online information while having truth labels bestowed on them by crowd-sourced masses...

Samuel L Perry
As pornography use continues to increase in the U.S., studies have sought to understand its potential influence on marital relationships. Yet, the primary focus of such studies has been pornography's association with marital quality, not stability. Consequently, we still know relatively little about whether pornography consumption at one time predicts marital disruption later on. Drawing on data from the 2006 and 2012 waves of the nationally representative Portraits of American Life Study (N = 445), this article examined whether married Americans who viewed pornography in 2006, either at all or in greater frequencies, were more likely to experience a marital separation by 2012...

High-quality chromosome images of mitotic and meiotic cell divisions in plant tissues are inextricably connected with the technical control of cell spread preparations. Superb chromosome slides are the best for studying chromosome morphology and making karyotypes; they also are the best start for a successful fluorescent in situ hybridization experiment. In this study, we describe the essentials for fixation, enzymatic digestion, squash, spread, and dropping protocols for clean and well-differentiated nuclei and chromosome complements...
