Melatonin enhances vertical bone augmentation in rat calvaria secluded spaces.
2015
Background Melatonin has many roles, including bone remodeling and osseointegration of dental implants. The topical application of melatonin facilitated bone regeneration in bone defects. We evaluated the effects of topical application of melatonin on vertical bone augmentation in rat calvaria secluded spaces. Material and Methods In total, 12 male Fischer rats were used and two plastic caps were fixed in the calvarium. One plastic cap was filled with melatonin powder and the other was left empty. Results Newly generated bone at bone defects and within the plastic caps was evaluated using micro-CT and histological sections. New bone regeneration within the plastic cap was increased signific…
Chest Surgery for Transgender and Gender Nonconforming Individuals
2018
Chest surgery can greatly facilitate the experience of living in a gender role. For transfeminine chest surgery, most surgeons recommend a 12-month period of feminizing hormone therapy prior to breast augmentation. For those who already have some breast volume due to hormone treatment, lipofilling can be a good option. Transmasculine chest surgery includes mastectomy and creation of a male chest. Preoperative parameters to be evaluated include breast volume, degree of excess skin, nipple-areola complex size and position, and skin elasticity. The algorithm the authors developed and modified can help choose from 5 techniques, resulting in an aesthetically pleasing male chest.
Treatment of Iatrogenic Functional or Morphologic Bladder Loss
1988
From 1984 to 1986, six children from 4 to 13 years of age, received a bladder augmentation by ileocecal cystoplasty (Mainz-pouch technique) because of an iatrogenic functional or morphologic bladder loss. Indications for operation were incontinence due to the low bladder capacity or threat to the upper urinary tract due to ureteral obstruction or vesicorenal reflux. Two of the children had already undergone supravesical urinary diversion by sigmoid conduit. After a follow-up period of 2 to 19 months, (mean 11 months), five of the six children are completely continent. One boy with a known weak sphincter still has slight, but decreasing, enuresis nocturna in periods of complete filling of th…
Rhabdomyosarcoma of the bladder, prostate or vagina: the role of surgery
2003
Rhabdomyosarcoma of pelvic organs is not common enough for many people to develop large series. However, the authors from Mainz retrospectively analysed 107 children with this condition, and suggest that primary chemotherapy followed by radical surgery yields excellent cure rates. OBJECTIVE To retrospectively analyse the outcome of children with rhabdomyosarcoma (RMS) of the bladder, prostate or vagina who were treated with chemotherapy, with or without radical surgery or additional radiotherapy, at our institution since 1968. PATIENTS AND METHODS From a total of 107 children with RMS seen between 1968 and December 2001, 22 (mean age 5.9, range 0.5–18) had RMS of bladder/prostate or vagina.…
In vivo versus augmented reality exposure in the treatment of small animal phobia: A randomized controlled trial
2016
Although in vivo exposure is the treatment of choice for specific phobias, some acceptability problems have been associated with it. Virtual Reality exposure has been shown to be as effective as in vivo exposure, and it is widely accepted for the treatment of specific phobias, but only preliminary data are available in the literature about the efficacy of Augmented Reality. The purpose of the present study was to examine the efficacy and acceptance of two treatment conditions for specific phobias in which the exposure component was applied in different ways: In vivo exposure (N = 31) versus an Augmented Reality system (N = 32) in a randomized controlled trial. “One-session treatment” guidel…
Virtual and augmented reality: Advancing research in consumer marketing
2020
Abstract Virtual reality (VR) and augmented reality (AR) technologies are having a profound impact on a variety of marketing practices and are attracting increasing attention from marketing researchers. In this article, we review developments in VR/AR applications and research in the area of consumer marketing. We propose a conceptual framework for VR/AR research in consumer marketing that centers around consumer experiences provided by VR/AR applications along the customer journey and the effectiveness of such applications, and delve into the key concepts and components of the framework. Next, we provide a comprehensive overview of VR/AR applications in current practices and extant researc…
Consumer behavior with augmented reality in retail: a review and research agenda
2021
Driven by the rapid technological development and adoption of augmented reality (AR) in retail, academic research has grown rapidly. Our purpose is to understand the reasons why consumers use augmented reality in retail and what outcomes retailers can expect. This study presents a systematic literature review and summarizes the current empirical knowledge on consumer behavior with AR in retail. This topic remains scattered between various literature streams showing that the potential of AR to create value for consumers lays in its ability to generate utilitarian and hedonic value, to improve decision-making, and to enhance personalization of the virtual self. Then, this study warns about ne…
The emperor’s new clothes : self-explorative engagement in virtual try-on service experiences positively impacts brand outcomes
2023
Purpose Virtual try-on (VTO) technology offers an opportunity for fashion and beauty brands to provide enriched self-explorative experiences. The increased popularity of VTOs makes it urgent to understand the drivers and consequences of the exploration of styles in VTO contexts (herein called self-explorative engagement). Notably, little is known about the antecedent and outcomes of the personalized self-explorative experience central to VTOs. This paper aims to fill this knowledge gap. Design/methodology/approach An online quasi-experiment (N = 500) was conducted in the context of fashion and beauty VTOs. Participants were asked to virtually try on sunglasses or lipsticks and subsequently…
Gradient-enhanced model and its micromorphic regularization for simulation of Lüders-like bands in shape memory alloys
2018
Abstract Shape memory alloys, notably NiTi, often exhibit softening pseudoelastic response that results in formation and propagation of Luders-like bands upon loading, for instance, in uniaxial tension. A common approach to modelling softening and strain localization is to resort to gradient-enhanced formulations that are capable of restoring well-posedness of the boundary-value problem. This approach is also followed in the present paper by introducing a gradient-enhancement into a simple one-dimensional model of pseudoelasticity. In order to facilitate computational treatment, a micromorphic-type regularization of the gradient-enhanced model is subsequently performed. The formulation empl…
Electronic structure calculations with GPAW: a real-space implementation of the projector augmented-wave method.
2011
Electronic structure calculations have become an indispensable tool in many areas of materials science and quantum chemistry. Even though the Kohn-Sham formulation of the density-functional theory (DFT) simplifies the many-body problem significantly, one is still confronted with several numerical challenges. In this article we present the projector augmented-wave (PAW) method as implemented in the GPAW program package (https://wiki.fysik.dtu.dk/gpaw) using a uniform real-space grid representation of the electronic wavefunctions. Compared to more traditional plane wave or localized basis set approaches, real-space grids offer several advantages, most notably good computational scalability an…
