Nanofabricated high turn-density spiral coils for on-chip electromagneto-optical conversion.

Circuit-integrated electromagnets are fundamental building blocks for on-chip signal transduction, modulation, and tunability, with specific applications in environmental and biomedical micromagnetometry. A primary challenge for improving performance is pushing quality limitations while minimizing size and fabrication complexity and retaining spatial capabilities. Recent efforts have exploited highly involved three-dimensional synthesis, advanced insulation, and exotic material compositions.

Wireless Recording of Cortical Activity by an Ion-Sensitive Field Effect Transistor.

Wireless brain technologies are empowering basic neuroscience and clinical neurology by offering new platforms that minimize invasiveness and refine possibilities during electrophysiological recording and stimulation. Despite their advantages, most systems require on-board power supply and sizeable transmission circuitry, enforcing a lower bound for miniaturization. Designing new minimalistic architectures that can efficiently sense neurophysiological events will open the door to standalone microscale sensors and minimally invasive delivery of multiple sensors.

Psychometric and Perceptometric Comparisons of the Perspectives of Orthodontists, Oral and Maxillofacial Surgeons, and Laypeople of Different Ages and Sexes towards Beauty of Female Jaw Angles (Intergonial Widths and Gonial Heights) on Frontal and Three-Quarter Views.

Objectives: The jaw angle plays an important role in facial beauty. Therefore, this study is aimed at comparatively determining the range of most attractive female intergonial widths and gonial heights on Perceptometric frontal-view and three-quarter-view images, from the perspective of orthodontists, oral maxillofacial (OMF) surgeons, and laypeople of different ages and sexes.

Methods: This prospective multivariate Perceptometric study was performed on 4191 esthetic scores given by 127 individuals to 33 Perceptometric face images.

Impact of Educational Interventions on Knowledge About Hypertensive Disorders of Pregnancy Among Pregnant Women: A Systematic Review.

Background: Hypertensive disorders of pregnancy (HDP), including chronic hypertension, preeclampsia and gestational hypertension, is the cause of about 50,000 deaths out of 400,000 perinatal deaths. HDP is an effective risk factor in stroke, type 2 diabetes, and cardiovascular diseases like ischemic heart disease. There is a significant relation between HDP, lifestyle, and knowledge.

Enhanced magnetic transduction of neuronal activity by nanofabricated inductors quantified via finite element analysis.

Methods for the detection of neural signals involve a compromise between invasiveness, spatiotemporal resolution, and the number of neurons or brain regions recorded. Electrode-based probes provide excellent response but usually require transcranial wiring and capture activity from limited neuronal populations. Noninvasive methods such as electroencephalography and magnetoencephalography offer fast readouts of field potentials or biomagnetic signals, respectively, but have spatial constraints that prohibit recording from single neurons.

Effect of multiple firings on the shear bond strength of presintered cobalt-chromium alloy and veneering ceramic.

Statement Of Problem: How multiple firing cycles may affect the oxide layer and, consequently, the shear bond strength of metal-ceramic restorations is unclear.

Purpose: The purpose of this in vitro study was to determine the effect of multiple firings on the shear bond strength of porcelain to cobalt-chromium (Co-Cr) alloy.

Comparing success of immediate versus delay loading of implants in fresh sockets: a systematic review and meta-analysis.

Background And Aims: The replacement of teeth with osseointegrated implants is one of the significant advances in the field of restorative dentistry. The time interval between tooth extraction and the implant can be very short or long. This systematic review and meta-analysis aimed to collect and evaluate articles related to determining the effect of instant loading of dental implants are placed in the fresh socket initial stability on the clinical success of the implant compared to delay loading dental implants.

The effect of novel simple saffron syrup on fatigue reduction in patients with multiple sclerosis.

Practical Classification of Upper Lateral Cartilage in Middle Vault Asymmetry.

Background: Middle vault asymmetry is a common reason for retained postoperative deviations. Although minor deformities can be camouflaged with cartilage, soft-tissue materials, or injectable fillers, comprehensive observation of upper lateral cartilage and subsequent topographic classification in major anatomical anomalies will help surgeons better plan their procedures to obtain better symmetry.

Methods: Photographs of 71 randomly selected primary open rhinoplasty patients were analyzed for anatomical presentation of their upper lateral cartilage.

Design and assessment of psychometric features of life skills inventory.

Introduction: The importance of life skills and their application in promoting personal, family, and occupational health in military personnel is well recognized. It is, therefore, important to identify and assess life skills in military personnel with a valid and reliable tool. The present study aims to develop such a tool and evaluate its psychometric features in military personnel.

Laterality and Left-sidedness in the Nose, Face, and Body: A New Finding.

Background: Asymmetry is a common occurrence in bilaterian animals, particularly human beings. Through examination of patients and their photographs during rhinoplasty, we noted wider left-sided nasal and facial features in most patients. This observation led us to hypothesize that this might be consistent to the whole body.
