It has been observed that the properties of room temperature ionic liquids near solid substrates are different from those of bulk liquids, and these properties play an important role in the development of catalysts, lubricants, and electrochemical devices. In this paper, we report microscopic studies of ionic liquid/solid interfaces performed using molecular dynamics simulations. The structural and dynamic properties of 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMIM-TFSI) on mica and graphite interfaces were thoroughly investigated to elucidate the microscopic origins of the formation of layered structures at the interfaces...

Abrams's palatal roll technique has been used extensively to augment peri-implant soft tissues in the maxillary esthetic zone and has seen numerous modifications. An adaptation of the palatal roll technique is described here and its simplicity of application in three different scenarios is demonstrated. At second-stage implant surgery, a partial thickness initial incision followed by a palatal subepithelial dissection at the site of implant was done and a connective tissue graft with a buccal pedicle was obtained...

BACKGROUND: Renal cell carcinomas represent 85% of malignant renal tumors. Typically, the tumor remains asymptomatic a long time before the appearance of urologic clinical signs. In some cases, metastasis can precede the manifestations of the primary tumor. Different sites are potential metastatic localizations for renal tumors, including skull metastases who represent a very rare location. CASE DESCRIPTION: We report the case of a 65-year-old man presented after the appearance of a skull mass...

In this paper we introduce a methodology for hard and soft tissue quantification at proximal, intermediate and distal tibia sites using peripheral Quantitative Computed Tomography (pQCT) scans. Quantification of bone properties is crucial for estimating bone structure resistance to mechanical stress and adaptations to loading. Soft tissue variables can be computed to investigate muscle volume and density, muscle-bone relationship, and fat infiltration.
 Approach: We employed implicit active contour models and clustering techniques for automated segmentation and identification of bone, muscle and fat at 4%, 38%, and 66% tibia length...

BACKGROUND: Frequent blood glucose readings are the most cumbersome aspect of diabetes treatment for many patients. The noninvasive TensorTip Combo Glucometer (CoG) component employs dedicated mathematical algorithms to analyze the collected signal and to predict tissue glucose at the fingertip. This study presents the performance of the CoG (the invasive and the noninvasive components) during a standardized meal experiment. METHODS: Each of the 36 participants (18 females and males each, age: 49 ± 18 years, 14 healthy subjects, 6 type 1 and 16 type 2 patients) received a device for conducting calibration at home...

Radiation therapy plays an essential role in the treatment of cancer. In radiation therapy, the ideal radiation doses are delivered to the observed tumor while not affecting neighboring normal tissues. In three-dimensional computed tomography (3D-CT) scans, the contours of tumors and organs-at-risk (OARs) are often manually delineated by radiologists. The task is complicated and time-consuming, and the manually delineated results will be variable from different radiologists. We propose a semi-supervised contour detection algorithm, which firstly uses a few points of region of interest (ROI) as an approximate initialization...

Background: While traditional biological principles have suggested that fragments consisting of cartilage alone cannot be reaffixed to bone with expectable long-term healing, case reports of successful healing after fixation in younger patients indicate that this concept remains incompletely explored. Purpose: To evaluate the presenting features, techniques, healing rates, and clinical and radiological results in a cohort of pediatric and adolescent athletes who underwent fixation of traumatic chondral-only fragments in the knee...

Background: Leaf chlorophyll content (LCC) provides valuable information about plant physiology. Most of the published chlorophyll vegetation indices at the leaf level have been based on the spectral characteristics of the adaxial leaf surface, thus, they are not appropriate for estimating LCC when both the adaxial and abaxial leaf surfaces influence the spectral reflectance. We attempted to address this challenge by measuring the spectral reflectance of the adaxial and abaxial leaf surfaces of several plant species at different growth stages using a portable field spectroradiometer...

We recorded time-resolved infrared absorption spectra of transient species produced on irradiation at 308 nm of a flowing mixture of CH 2 I 2 /O 2 /N 2 /SO 2 at 298 K. Bands of CH 2 OO were observed initially upon irradiation; their decrease in intensity was accompanied by the appearance of an intense band at 1391.5 cm -1 that is associated with the degenerate SO-stretching mode of SO 3 , two major bands of HCHO at 1502 and 1745 cm -1 , and five new bands near >1340, 1225, 1100, 940, and 880 cm -1 . The band near 1340 cm -1 was interfered by absorption of SO 2 and SO 3 , so its band maximum might be greater than 1340 cm -1 ...

Patients with considerable maxillomandibular anteroposterior discrepancies and maxillary hypoplasia require corrective treatment through orthognathic surgery. However, in the treatment of severe maxillary retrognathism, it is necessary to reconstruct areas of bone deficiency through grafting techniques in addition to maxillary advancement using only the Le Fort I osteotomy. Treatment in these patients is more challenging and requires high surgical predictability. Alloplastic materials often have been used for the reconstruction of poor bone contours...

The aim of this study was to evaluate a new minimally invasive surgical technique for the reconstruction of critical-size bony defect with local harvested bone core with simultaneous implant placement. In a prospective study, 186 consecutively treated patients were included and controlled clinically and radiologically for at least 5 years postoperative. Every patient presented a bony defect affecting the buccal, lingual, or palatal wall. In all cases, the alveolar crest was wide enough to allow implant placement inside the bony contours...

The capture of high quality treatment and outcomes data is necessary in order to learn from our clinical experiences with big data analytics. In radiotherapy, there are several practical challenges to overcome. Practical aspects of data collection are discussed pointing to a need for a culture change in clinical practice to one that captures structured patient related data in routine care in a prospective manner. Radiation dosimetry and the contoured anatomy must also be captured routinely to represent the best estimate of delivered radiation...

We fabricated a floating GaN microdisk supported by a silicon pillar through photolithography, dry-etching GaN, and isotropic wet-etching silicon methods. Single-mode ultraviolet whispering gallery mode (WGM) lasing was obtained from the floating GaN microdisk under optical pumping conditions at room temperature. The features of WGM lasing, i.e., the threshold, emission intensity, and lasing mode number, were characterized. A two-dimensional finite-difference time-domain simulation about the optical field contour profile also confirmed the resonance mechanism of WGM lasing...

The clinical outcome after fat grafting for facial rejuvenation and contouring can be less optimal because lack of standardized techniques is performed by the surgeon for the procedure. In this review, the author has tried to provide a rationalized approach to fat grafting for facial rejuvenation and contouring. The preferred donor sites include low abdomen and inner thigh especially in younger patients. Fat grafts should be harvested with low negative pressure via syringe liposuction technique to ensure the integrity as well as the optimal level of cellular function...

The Bland-Altman (BA) and percentage error (PE) methods have been previously described to assess the agreement between 2 methods of medical or laboratory measurements. This type of approach raises several problems: the BA methodology constitutes a subjective approach to interchangeability, whereas the PE approach does not take into account the distribution of values over a range. We describe a new methodology that defines an interchangeability rate between 2 methods of measurement and cutoff values that determine the range of interchangeable values...

Cellular adhesion and differentiation is conditioned by the nanoscale disposition of the extracellular matrix (ECM) components, with local concentrations having a major effect. Here we present a method to obtain large-scale uneven nanopatterns of arginine-glycine-aspartic acid (RGD)-functionalized dendrimers that permit the nanoscale control of local RGD surface density. Nanopatterns are formed by surface adsorption of dendrimers from solutions at different initial concentrations and are characterized by water contact angle (CA), X-ray photoelectron spectroscopy (XPS), and scanning probe microscopy techniques such as scanning tunneling microscopy (STM) and atomic force microscopy (AFM)...

"Perioperative goal-directed therapy" (PGDT) aims at an optimization of basic and advanced global hemodynamic variables to maintain adequate oxygen delivery to the end-organs. PGDT protocols help to titrate fluids, vasopressors, or inotropes to hemodynamic target values. There is considerable evidence that PGDT can improve patient outcome in high-risk patients if both fluids and inotropes are administered to target hemodynamic variables reflecting blood flow. Despite this evidence, PGDT strategies aiming at an optimization of blood flow seem to be not well implemented in routine clinical care...
