The importance of eyebrows in facial aesthetics has long been recognized, and eyebrows restoration is carried out by carefully depositing pigments into the epidermis. This cosmetic procedure is known as microblading, and it is very popular because of the progress made on social media platforms. This study was designed to determine the awareness of eyebrow microblading, complication and laser removal in general population of Saudi Arabia.

Objectives: Sleep is an important determinant of quality of life. Sleep disturbance is concomitant with end-stage knee osteoarthritis for which total knee arthroplasty (TKA) is the most commonly done procedure. However, literature on this topic is lacking in terms of the impact of sleep quality on patient satisfaction after arthroplasty, especially the adverse associations of surgery on sleep quality.

Uptake hydrogenase (Hup) recycles H2 formed by nitrogenase during nitrogen fixation, thereby preserving energy. Among root nodule bacteria, most rhizobial strains examined are Hup-, while only one Hup-  Frankia inoculum had been identified. Previous analyses had led to the identification of two different [NiFe] hydrogenase syntons.

Background: Fecal microbiota transplantation (FMT) is an interventional approach to treat chronic and recurrent infection (CDI). However, there is insufficient evidence regarding its effectiveness and safety. Clinical trials have been conducted to inspect the safety and effectiveness of FMT with and without comparison to pharmacological treatments.

Coriariaceae are a small plant family of 14-17 species and subspecies that currently have a global but disjunct distribution. All species can form root nodules in symbiosis with diazotrophic Frankia cluster-2 strains, which form the earliest divergent symbiotic clade within this bacterial genus. Studies on Frankia cluster-2 mostly have focused on strains occurring in the northern hemisphere.

A critical missing component in the study of real-world falls is the ability to accurately determine impact forces resulting from the fall. Subject-specific rigid body dynamic (RBD) models calibrated to video captured falls can quantify impact forces and provide additional insights into injury risk factors. RBD models were developed based on five backward falls captured on surveillance video in long-term care facilities in British Columbia, Canada.

Non-human primate (NHP) spinal cord injury experiments exhibit high intersubject variability in biomechanical parameters even when a consistent impact protocol is applied to each subject. Optimizing impact parameters to reduce this variability through experiments is logistically challenging in NHP studies. Finite element models provide a complimentary tool to inform experimental design without the cost and complexity of live animal studies.

Large animal contusion models of spinal cord injury are an essential precursor to developing and evaluating treatment options for human spinal cord injury. Reducing variability in these experiments has been a recent focus as it increases the sensitivity with which treatment effects can be detected while simultaneously decreasing the number of animals required in a study. Here, we conducted a detailed review to explore if head and neck positioning in a cervical contusion model of spinal cord injury could be a factor impacting the biomechanics of a spinal cord injury, and thus, the resulting outcomes.

Introduction: Many researchers have suggested that bismuth composite shields (BCS) reduce breast dose remarkably; however, the level of this reduction and its impact on image quality has not been assessed. This study aimed to evaluate the efficiency of nano- and micro- BCS in reducing the dose and image quality during chest computed tomography (CT) scans.

Materials And Methods: Bismuth shields composed of 15 weighting percentage (wt%) and 20 wt% bismuth oxide (BiO) nano- and micro-particles mixed in silicon rubber polymer were constructed in 1 and 1.

Catheter-associated Urinary Tract Infection (CAUTI) has been studied worldwide as part of device-related healthcare infection. CAUTI is one of the most commonly reported infections in the literature, which occurs during clinical practice in Intensive Care Units (ICUs) and non-ICU departments. Many studies have covered the CAUTI rate in Saudi Arabia mainly in the ICU covering single or multiple hospitals as surveillance for device-related infections in the ICU.

infections (CDIs) are infamous healthcare-associated infections for causing watery diarrhea to long-term hospitalized patients with a high mortality rate. Epidemiological reports from western countries showed up-trending pattern in the number of CDIs cases. It is becoming immensely challenging for routine diagnostic protocols to detect CDIs accurately with short turnaround time.

The addition of short fibers has been experimentally observed to slow the stress relaxation of viscoelastic polymers, producing a change in the relaxation time constant. Our recent study attributed this effect of fibers on stress relaxation behavior to the interfacial shear stress transfer at the fiber-matrix interface. This model explained the effect of fiber addition on stress relaxation without the need to postulate structural changes at the interface.
