Nasal reconstruction has been articulated in the literature since 700 B.C. when the earliest iteration of the forehead flap was described in the Indian medical treatise, the Sushruta Samhita. Since then it has evolved into the interpolated flap which has served as a powerful tool for facial reconstruction. The interpolated flap is constructed from nonadjacent donor tissue that has an inherent blood supply. It requires a multistaged approach and is best suited for reconstruction of large or deep defects of the nose...

BACKGROUND: The skin and soft tissues of the face and neck have a rich plexus of dermal-subdermal vessels, which creates the possibility of raising a fasciocutaneous flap based on this vascular supply. A turned in fasciocutaneous island flap (TIFCIF) from an adjacent area of the defect can provide a simple substitute to many complex reconstructive procedures. MATERIALS AND METHODS: Fifteen patients underwent wide excision for oral cancer and upper neck dissection, maintaining bone framework, between August 2010 and June 2014...

BACKGROUND: Nasomaxillary hypoplasia is a rare congenital disorder involving the central face. It imparts a distinctive appearance to the individual face as the age advances. Severity of the disorder varies, so do the manifestations. METHODS: This was a retrospective study conducted on the records and photographic data of 560 rhinoplasty cases performed between 2006 March and 2016 March. About 16 cases of nasomaxillary hypoplasia were selected from the group and they were classified based on the severity of the features...

Rhododendron ferrugineum L. is a widespread dwarf shrub species growing in high-elevation, alpine environments of the Western European Alps. For this reason, analysis of its growth rings offers unique opportunities to push current dendrochronological networks into extreme environments and way beyond the treeline. Given that different species of the same genus have been successfully used in tree-ring investigations, notably in the Himalayas where Rhododendron spp. has proven to be a reliable climate proxy, this study aims at (i) evaluating the dendroclimatological potential of R...

BACKGROUND: Monolithic scintillators read out by arrays of photodetectors represent a promising solution to obtain high spatial resolution and the depth of interaction (DOI) of the annihilation photon. We have recently investigated a detector geometry composed of a monolithic scintillator readout on two sides by silicon photomultiplier (SiPM) arrays, and we have proposed two parameters for the DOI determination: the difference in the number of triggered SiPMs on the two sides of the detector and the difference in the maximum collected signal on a single SiPM on each side...

Many species of Schizothoracine, a sub-family of Cyprinidae, are highly endemic to the Qinghai-Tibetan Plateau (QTP). To characterize the adaptive changes associated with the Schizothoracine expansion in high-altitudes, we sequenced tissue transcriptomes of two highland and two sub-highland Schizothoracines, and analyzed gene evolution patterns by comparing to lowland cyprinids. Phylogenetic tree reconstruction and divergence time estimation indicated that the common ancestor of Schizothoracine fishes lived around 32...

Identifying the temporal progression of a set of biological samples is crucial for comprehending the dynamics of the underlying molecular interactions. It is often also a basic step in data denoising and synchronization. Finally, identifying the progression order is crucial for problems like cell lineage identification, disease progression, tumor classification, and epidemiology and thus impacts the spectrum of disciplines spanning basic biology, drug discovery, and public health. Current methods that attempt solving this problem face difficulty when it is necessary to factor-in complex relationships within the data such as grouping, partial ordering or bifurcating or multifurcating progressions...

INTRODUCTION: The anterolateral thigh perforator flap (ALT) represents the workhorse for most reconstructive efforts in the head and neck regions. The main advantages of this flap are its versatility, the length of the pedicle, and the low morbidity of the donor site. The major drawback is the bulkiness of this flap with the frequent need for secondary revisions. To overcome this, we have developed a novel way to harvest and inset the ALT, called the sandwich fascial ALT flap (SALT). METHODS: All patients undergoing head and neck reconstruction using the SALT flap from January 2013 to March 2016 were included in this retrospective analysis...

The maxilla is the most important bony support of the mid-face skeleton and is critical for both esthetics and function. Maxillary defects, resulting from tumor resection, can cause severe functional and cosmetic deformities. Furthermore, maxillary reconstruction presents a great challenge for oral and maxillofacial surgeons. Nowadays, vascularized composite bone flap transfer has been widely used for functional maxillary reconstruction. In the last decade, we have performed a comprehensive research on functional maxillary reconstruction with free fibula flap and reported excellent functional and acceptable esthetic results...

BACKGROUND: Animal models of human behavioural deficits involve conducting experiments on animals with the hope of gaining new knowledge that can be applied to humans. This paper aims to address risks, biases, and fallacies associated with drawing conclusions when conducting experiments on animals, with focus on animal models of mental illness. CONCLUSIONS: Researchers using animal models are susceptible to a fallacy known as false analogy, where inferences based on assumptions of similarities between animals and humans can potentially lead to an incorrect conclusion...

Corrosion processes in two North Sea oil production pipelines were studied by analyzing pig envelope samples via metagenomic and metabolomic techniques. Both production systems have similar physico-chemical properties and injection waters are treated with nitrate, but one pipeline experiences severe corrosion and the other does not. Early and late pigging material was collected to gain insight into the potential causes for differential corrosion rates. Metabolites were extracted and analyzed via ultra-high performance liquid chromatography/high-resolution mass spectrometry with electrospray ionization (ESI) in both positive and negative ion modes...

The International 10/20 system is an important head-surface-based positioning system for transcranial brain mapping techniques, e.g., fNIRS and TMS. As guidance for probe placement, the 10/20 system permits both proper ROI coverage and spatial consistency among multiple subjects and experiments in a MRI-free context. However, the traditional manual approach to the identification of 10/20 landmarks faces problems in reliability and time cost. In this study, we propose a semi-automatic method to address these problems...

Shaping chemical interfaces of hard and soft matter materials into physical morphologies that guarantee excellent transport properties is of central importance for technologies relying on adsorption, separation, and reaction at the interface. Polymer monoliths with a hierarchically structured pore space, for example, are widely used in flow-driven processes, whose efficiency depends on the morphology of the support material over several length scales. Compared with alternative support structures, particularly silica monoliths, polymer monoliths yield lower efficiency, which suggests a suboptimal morphology...

Ψ-Glutathione (ψ-GSH) is an orally bioavailable and metabolism-resistant glutathione analogue that has been shown previously to substitute glutathione in most of its biochemical roles. Described here in its entirety is the preclinical evaluation of ψ-GSH as a rescue agent for acetaminophen (APAP) overdose: an event where time is of essence. By employing a murine model, four scenarios commonly encountered in emergency medicine are reconstructed. ψ-GSH is juxtaposed against N-acetylcysteine (NAC), the sole clinically available drug, in each of the scenarios...

CONTEXT: The most common malignant tumours of the face are basal cell carcinoma, squamous cell carcinoma and melanoma. While the results of skin graft are less than satisfactory for large areas to cover, distant flaps are bulky with a poor colour match. Local fasciocutaneous flaps provide reasonable option for reconstruction of facial defects with good colour and texture match and good success rate. AIMS: This study aimed to analyse the various modalities of reconstruction after resection of facial malignancies and their advantages and disadvantages...

A clinical case illustrates and explains step by step a minimally invasive molar occlusal surface preparation for all-ceramic bonded restoration. The sequential use of calibrated burs, following the specific procedure, systematically and quickly, provides a perfectly calibrated reduction of the occlusal face even for an inexperienced practitioner. This preparation increases the bonding surface and optimizes the accommodation of constraints that provides a more resistant reconstruction and favors the preservation of the vital tooth...

BACKGROUND: The decision whether or not to undergo pelvic reconstructive surgery is difficult for women suffering from pelvic organ prolapse. However, little research has examined the symptom distress and life impacts that these women face prior to this surgery. Thus, it is crucial that gynecology nurses learn about these life impacts and symptom distresses in order to help these women make the best decisions with regard to surgery. PURPOSE: To explore the life impacts and degree of symptom distress in pre-surgery women with pelvic organ prolapse; to explore the relationships between demographic data and the variables of life impact and degree of symptom distress; and to identify the factors that relate to the explainable variance in the life impacts of these women...

Ten years after the first face transplantation we report the partial loss of this graft. After two episodes of acute rejection (AR) occurred and completely reversed in the first post-transplantation year, ninety months post-transplantation the patient developed de novo class II-donor specific antibodies, without clinical signs of AR. Some months later she developed several skin rejection episodes treated with steroid pulses. Despite rapid clinical improvement, some months later the sentinel skin graft underwent necrosis...
