Comparison of the biomechanical effect of distal implants placed at different angles in the all-on-four technique: A nonlinear finite element analysis.

Introduction: The "All-on-four" technique addresses this by placing two vertical implants in the anterior region and two posterior implants angled up to 45°. This study evaluates stress distribution on bone, implants, abutments, gingiva, and prostheses based on posterior implant angulation, using both standard and angled neck implants. Additionally, angled neck implants were used alongside standard implants.

The relationship between general and abdominal obesity, nutrition and respiratory functions in adult asthmatics.

Objective: Although obesity is known to have adverse effects on asthma, it is not fully known whether general or abdominal obesity affects asthma symptoms more. In this study, the effects of diet and general/abdominal obesity on respiratory functions were evaluated.

Methods: A total of 204 adult asthmatic individuals participated in the study.

Combining vancomycin-modified gold nanorod arrays and colloidal nanoparticles as a sandwich model for the discrimination of Gram-positive bacteria and their detection via surface-enhanced Raman spectroscopy (SERS).

This study reports the development of a highly sensitive antibiotic-based discrimination and sensor platform for the detection of Gram-positive bacteria through surface-enhanced Raman spectroscopy (SERS). Herein, a combination of gold nanorod arrays (GNAs) and colloidal gold nanoparticles (AuNPs) was used as a SERS platform. To specifically capture Gram-positive bacteria, both GNAs and AuNPs were functionalized with thiol-modified vancomycin (HS-Van) molecules.

Abdominal palpation and percussion maneuvers do not affect bowel sounds.

One of two local anesthetic agents (Marcaine and Jetokain Simplex) was randomly selected for tooth extractions.

The effects of obesity on pulmonary function in adults with asthma.

Objective: While the effects of obesity on asthma are unclear, an increased body mass index (BMI) is known to enhance the symptoms and severity of asthma and to impair asthma control. The present study evaluates the effects of nutritional habits and obesity on pulmonary function and asthma control in individuals with asthma.

Methods: This cross-sectional study included 60 obese respondents and 60 respondents with normal body weight, who were referred to pulmonology clinics over a period of 2 months.

Bright-field holography: cross-modality deep learning enables snapshot 3D imaging with bright-field contrast using a single hologram.

Digital holographic microscopy enables the 3D reconstruction of volumetric samples from a single-snapshot hologram. However, unlike a conventional bright-field microscopy image, the quality of holographic reconstructions is compromised by interference fringes as a result of twin images and out-of-plane objects. Here, we demonstrate that cross-modality deep learning using a generative adversarial network (GAN) can endow holographic images of a sample volume with bright-field microscopy contrast, combining the volumetric imaging capability of holography with the speckle- and artifact-free image contrast of incoherent bright-field microscopy.

A stepped approach for the management of symptomatic internal derangement of the temporomandibular joint.

Background: Internal derangement is the clinical and pathological condition of disc displacement of the temporomandibular joint. Management of these cases involve conservative and surgical treatment options. Minimally invasive surgical procedures namely arthrocentesis and arthroscopy are promising techniques in the management of internal derangement.

Concurrent medullary and papillary carcinoma of thyroid.

Simultaneous occurrence of papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC) in the same thyroid gland is a rare condition. These tumors derive from different cells; PTC originates from follicular cells whereas MTC originates from parafollicular cells. Because of this, the treatment of these tumors also differs.

Lidocaine versus mepivacaine in sedated pediatric dental patients: randomized, prospective clinical study.

Unlabelled: Dental anxiety is usually seen in the pediatric patients. specially in the case of minor oral surgical procedures and exodontia, cooperation of the patients and their families with the dentist will lead to superior treatment outcomes. Pain control is important in dentistry.

Sensorineural hearing loss in pediatric patients with celiac disease.

Sensorineural hearing loss (SNHL) as an extraintestinal manifestation of celiac disease (CD) has been reported in several studies. The aim of this study was to determine presence of subclinical sensorineural hearing loss associated with CD in pediatric patients. Otoscopy, tympanometry and pure tone audiometry were performed in 44 patients with CD and 20 healthy age and sex-matched controls.

Enhancing quality of life and mastery of informal caregivers of high-grade glioma patients: a randomized controlled trial.

High-grade gliomas (HGG) are serious primary brain tumors that may prevent the patient from functioning normally in social, emotional and cognitive respect. Often the partner's role will convert to that of informal caregiver. Consequently, they may experience significant stress and reductions in caregiver mastery, negatively affecting their health-related quality of life (HRQOL).
