Correction Factor Evaluation and Between-System Comparison of Behavioral Threshold Predictions From Auditory Brainstem Response Measures in Infants.

Purpose: Auditory brainstem response (ABR) thresholds are corrected to estimate behavioral thresholds in infants. Corrections were validated, and a comparison of behavioral threshold estimates between systems was conducted to inform equipment transition and protocols in Ontario, Canada.

Method: In Study 1, a retrospective file review was conducted.

Examining Force Level Output of Skin-Drive Bone Conduction Hearing Devices in Adults With Simulated Conductive Hearing Loss.

Purpose: Bone conduction hearing devices (BCDs) that deliver sound across the skin (i.e., transcutaneous) are suitable for some individuals who have conductive or mixed hearing losses.

An Innovative Design for the Vaginal Speculum.

Introduction: The main objective of this study is to evaluate the effectiveness of a newly designed vaginal speculum, the , in-vitro. The setting of this study was at Florida International University and involved four senior students in the Department of Biomedical Engineering.

Methods: A phantom vaginal model was used to test three variables of the (Visibility, Pressure and Gynecologic Tools tests).

Ameliorative Effects of some Natural Antioxidants against Blood and Cardiovascular Toxicity of Oral Subchronic Exposure to Silicon Dioxide, Aluminum Oxide, or Zinc Oxide Nanoparticles in Wistar Rats.

The present study determines the possible protective role of fig fruit extract with olive oil and date palm fruit extract (FOD) in decreasing the oral subchronic blood and cardiovascular toxicity of SiONPs, AlONPs, or ZnONPs. The present study used 80 male Wistar rats (8 groups, = 10) distributed according to the treatment. The FOD treatments were used at their recommended antioxidant doses.

Implementation process evaluation of an ergonomic train the trainer program: How to learn from mechanisms and the temporal structure of processes?

In implementation process evaluation, the analysis of the temporal structure of processes is key for understanding the successive interactions between the flow of practitioners' actions and evolving workplace reactions and context. However, capturing the temporal structure of processes in data analysis is a methodological challenge, and available literature to overcome this challenge is scarce, especially for workplace ergonomic interventions. The aim of this paper was to perform an implementation process evaluation of an ergonomic train the trainer program taking into account the temporal structure of processes.

Clinical consensus document for fitting non-surgical transcutaneous bone conduction hearing devices to children.

This clinical consensus document addresses the assessment, selection, and fitting considerations for non-surgical bone conduction hearing devices (BCHD) for children under the age of 5 years identified as having unilateral or bilateral, permanent conductive or mixed hearing losses. Children with profound unilateral sensorineural hearing losses are not addressed. The document was developed based on evidence review and consensus by The Paediatric Bone Conduction Working Group, which is composed of audiologists from North America who have experience working with BCHDs in children.

Arrhythmia classification from single-lead ECG signals using the inter-patient paradigm.

Background And Objectives: Arrhythmia is a heart disease characterized by the change in the regularity of the heartbeat. Since this disorder can occur sporadically, Holter devices are used for continuous long-term monitoring of the subject's electrocardiogram (ECG). In this process, a large volume of data is generated.

Immunohistochemical Expression of BRCA1 Protein, ER, PR and Her2/neu in Breast Cancer: A Clinicopathological Study.

Unlabelled: Breast cancer is a heterogeneous hormone-dependent disease. Potential prognosis depends on the clinicopathological evaluation and assessment of other prognostic indicators. The detection of the oestrogen Receptor (ER), Progesterone Receptor (PR), Human epidermal growth factor receptor 2 (Her2/neu) and BRCA1 oncoprotein is pivotal for prognostic evaluation and to choose the appropriate post-surgical adjuvant therapy beside selecting the proper candidate for genetic counselling.

Work-related Musculoskeletal Pain among Different Dental Specialists in United Arab Emirates.

Introduction: Dentists are at a very high risk of developing work-related musculoskeletal pain. The present study aimed at studying the prevalence of musculoskeletal pain among different dental specialists in the United Arab Emirates (UAE), and correlating the region of pain with the type of clinical work done by the specialists.

Materials And Methods: A sample of more than 100 dentists was chosen randomly from different emirates in UAE.

Dynamical behavior of two predators competing over a single prey.

Dynamical behavior of a food web comprising two predators competing over a single prey has been investigated. The analysis of the food web model shows that the persistence is not possible for two competing predators sharing a single prey species in the cases when any one of the boundary prey-predator planes has a stable equilibrium point. The principle of competitive exclusion holds in such cases.
