Unusual presentation of dermatofibroma on the face: Case report.

Dermatofibroma (DF; Benign Fibrous Histiocytoma) seldom presents on the face. We present an unusual case presentation of translucent nodule on the upper right cheek of the face which was diagnosed clinically as basal cell carcinoma. Physician should include DF in the differential of such lesions.

Molecular alterations of mitochondrial D-loop in oral leukoplakia.

Background: Over the years, numerous studies proposed a crucial role of mutations of nuclear DNA in the carcinogenesis process. Of late, many researchers suppose that alterations of mitochondrial DNA should not be excepted from this analysis. Mutational analysis of mitochondrial DNA displayed that mitochondrial D-loop is assessed as a hotspot for molecular alterations in various types of malignant tumors encompassing oral squamous cell carcinoma.

A Novel Non-invasive Technique of Measuring Bilirubin Levels Using BiliCapture.

Objectives: In preterm infants, hyperbilirubinemia is common and can impair the central nervous system. The tests available for measuring bilirubin is to collect blood from heel pricking and occasionally taking blood samples from inserted cannulas, which is painful. Therefore, there is a need to develop a non-invasive device to detect bilirubin levels in newborns and interpret the severity of jaundice.

Preparation, characterization of silver phyto nanoparticles and their impact on growth potential of L. seedlings.

The current study reports rapid and easy method for synthesis of eco-friendly silver nanoparticles (AgNPs) using leaves extract as a reducing and covering agent. The bio-reductive synthesis of AgNPs was monitored using a scanning double beam UV-vis spectrophotometer. Transmission electron microscopy (TEM) was used to characterize the morphology of AgNPs obtained from plant extracts.

Factors affecting participation in physical activities in Saudi children with Down syndrome: mothers' perspectives.

Purpose: Physical activity provides a wide range of benefits. Several studies conducted in various countries have examined factors influencing participation in physical activities in children with Down syndrome. This study aimed to explore factors affecting participation in physical activities in Saudi children with DS, from their mothers' perspectives.

Vestibular vertigo is associated with abnormal sleep duration.

Background/objective: Several small studies in animals and humans have suggested a relationship between vestibular function and sleep. In this study, we evaluate the association between vestibular vertigo and sleep duration in a large, representative sample of US adults.

Methods: We used data from the National Health Interview Survey, which administered a Balance Supplement in 2008 in a sample of 20,950 adult respondents.

Stain Deconvolution Using Statistical Analysis of Multi-Resolution Stain Colour Representation.

Stain colour estimation is a prominent factor of the analysis pipeline in most of histology image processing algorithms. Providing a reliable and efficient stain colour deconvolution approach is fundamental for robust algorithm. In this paper, we propose a novel method for stain colour deconvolution of histology images.

Using VARK to assess Saudi nursing students' learning style preferences: Do they differ from other health professionals?

Objectives: This study aimed to develop knowledge about the preferred learning styles of Saudi nursing students that can lead students to understand course content and, in turn, offer improved patient care.

Methods: A cross-sectional survey design was administered to 125 female nursing students who volunteered to participate in this research.

Results: The majority of participants (80.

Vitamin D receptor deficiency impairs inner ear development in zebrafish.

The biological actions of vitamin D are largely mediated through binding to the vitamin D receptor (VDR), a member of the nuclear hormone receptor family, which regulates gene expression in a wide variety of tissues and cells. Mutations in VDR gene have been implicated in ear disorders (hearing loss and balance disorder) but the mechanisms are not well established. In this study, to investigate the role of VDR in inner ear development, morpholino-mediated gene knockdown approaches were used in zebrafish model system.

Vitamin D receptor signaling is required for heart development in zebrafish embryo.

Vitamin D has been found to be associated with cardiovascular diseases. However, the role of vitamin D in heart development during embryonic period is largely unknown. Vitamin D induces its genomic effects through its nuclear receptor, the vitamin D receptor (VDR).

An educational programme for nursing college staff and students during a MERS- coronavirus outbreak in Saudi Arabia.

Background: The Middle Eastern Respiratory Syndrome Coronavirus is a serious and emerging issue in Saudi Arabia and the world. A response was required to reduce possible disease transmission between the hospital and university. College of Nursing academic staff developed a programme in response to the educational and emotional needs of participants.
