Indoor carbon monoxide exposures in a retail occupancy.

In a two-story retail mall in the Southeastern United States, employees within Store A (located on the second level) began to feel headaches and general unease and discussed the symptoms among themselves. Approximately 1.5 hr later, an employee called 9-1-1.

Evaluation of the presence of the premaxillary-maxillary suture in growing patients: A retrospective CBCT study.

Background: The premaxillary-maxillary suture (PMS) is related to midface development, but its exact closure period remains undefined. Some authors consider the premaxilla as an independent bone with potential for orthopaedic stimulation, while others see it as a phylogenetic vestige.

Objective: To determine the prevalence of the premaxillary-maxillary suture (PMS) in cone beam computed tomography (CBCT) images of patients aged 6 to 16years, according to age and sex, treated at the Dental Clinic of the Pontificia Universidad Católica de Chile's Oral Imaging Service between 2015 and 2023.

Turning of 42CrMo4+QT under different scenarios: Dataset of machining, roughness and residual stress.

The turning process remains one of the most widely used manufacturing methods in the industry due to its high flexibility and production rates. Despite being an extensively used technique, the impact of this machining process on the surface integrity of the components has not yet been resolved in the literature, although it is well known that it can have a major influence on their final life. With the aim of providing new insights in the field, an extensive experimental campaign was designed on a 42CrMo4 quenched and tempered steel (in the following 42CrMo4+QT) using the response surface method.

Active Surveillance in Non-Muscle Invasive Bladder Cancer, the Potential Role of Biomarkers: A Systematic Review.

Bladder cancer (BC) is the tenth most common cause of cancer worldwide and is the thirteenth leading cause of cancer mortality. The non-muscle invasive (NMI) variant represents 75% of cases and has a mortality rate of less than 1%; however, it has a high recurrence rate. The gold standard of management is transurethral resection in the case of new lesions.

Endogenous endophthalmitis secondary to perirenal abscess.

Introduction: Endogenous Endophthalmitis is a rare ocular infection but with poor visual prognosis for most patients. Its most frequent etiology is spp., associated with hepatic abscesses and less frequently with perirenal abscesses.
