Purpose: Describe the various presentations of the rare entity of orbital wall infarction secondary to sickle cell disease and highlight the importance of magnetic resonance imaging in differentiating the entity from other similar diagnoses.
Observation: A 4-year-old child presented to the hospital with bilateral recurrent painless orbital wall infarction secondary to sickle cell disease. Orbital wall infarctions have been described before in the literature; However, the painless and recurrent nature is intriguing.
Introduction: Inappropriate visits (IVs) and overcrowded emergency departments (EDs) can result in many complications for patients and medical staff. This study aimed to assess the incidence, associated factors, and predictive factors of IVs to ED.
Methods: This retrospective cohort single-center study was conducted in the ED of King Abdulaziz Medical City, Jeddah, Saudi Arabia.
In the realm of agricultural sustainability, the utilization of plant genetic resources for enhanced disease resistance is paramount. Preservation efforts in genebanks are justified by their potential contributions to future crop improvement. To capitalize on the potential of plant genetic resources, we focused on a barley core collection from the German ex situ genebank and contrasted it with a European elite collection.

This qualitative study aimed to investigate the driving forces behind drug use, the factors contributing to drug cessation, and the elements influencing the recovery process.
Methods: Data were extracted from clinical records provided by The Greenhouse Community Services Limited between January 2020 to May 2022.
Background In the last two decades, drug overdose has globally become a major player in patients' morbidity and mortality events. Opioids, in particular, have been always the main part of this equation in different communities as they correspond, for instance, to one-third of poisoning deaths in The United States of America (USA). Aim This study aimed to measure the variation in opioid-analgesia (OA) prescription behavior among emergency medicine (EM) physicians working in different hospitals in the Western Region of Saudi Arabia.

Although it is an independent ophthalmological subspecialty, many procedures fall within the shared scope and anatomical area of oculoplastic surgery, otorhinolaryngology, and plastic and reconstructive surgery, which tend to confuse physicians and patients seeking medical advice. In this study, our goal is to evaluate the perception of oculoplastic surgery among the public and physicians.

Chief residents have historically been viewed as "middle managers", and other leadership roles include administrative work, teaching, and advocacy for residents. Chief residents also help in managing the logistics of complex healthcare systems and mediating between many groups with conflicting needs and perspectives.
View Article and Find Full Text PDFOpioids are the mainstay of treatment for acute pain in the emergency department. However, its misuse led to the investigation of alternative effective analgesic options for acute pain complaints such as ketamine. Therefore, this systematic review and meta-analysis aimed to determine the effectiveness of ketamine in comparison to opioids in the management of acute pain.

The present study aimed to determine prenatal auditory stimulation effects on serum levels of ceruloplasmin (CPN), alpha-1-acid glycoprotein (AGP), corticosterone (CORT), and heat shock protein 70 (Hsp70) regulations in developing chicken embryos and newly hatched chicks. Hatching eggs were subjected to the following auditory treatments; 1) control (no additional sound treatment other than the background sound of the incubator's compressors at 40 dB), 2) noise exposure (eggs were exposed to pre-recorded traffic noise at 90 dB) (NOISE), and 3) music exposure (eggs were exposed to Mozart's Sonata for Two Pianos in D Major, K 488 at 90 dB) (MUSIC).

The developed AN/NC-DEGDN formulation was successfully obtained through a casting process and fully characterized in terms of its chemical structure, morphological features, and thermal behavior. Beforehand, theoretical calculation by the CEA-NASA program was applied to select the optimal composition of the formulation.

This study was designed to delineate the effects of prenatal thermal stress on serum levels of acute-phase proteins (APPs), namely ceruloplasmin (CPN) and alpha-1-acid glycoprotein (AGP), the regulation of brain mRNA levels of heat shock protein (Hsp) 70, and serum levels of corticosterone (CORT) in embryos and neonatal chicks. Hatching eggs were subjected to three thermal treatments; (i) standard optimum temperature throughout (SS: 37.

For a comparison purpose, the heat release, cost, density and hygroscopicity of the different co-crystals were evaluated. The obtained results indicated that HNTO/AN at the 1 : 3 ratio exhibited a higher heat release, better thermal stability, low water content and a reasonable cost, compared to other co-crystals.

Renewed efforts have been made to dissect the phenotypic variation and genetic basis of hybrid floral traits, although the potential of tailoring the appropriate flower design on seed setting is less known. To this end, elite wheat genotypes were crossed using a chemical hybridizing agent at different doses.

Methods: This cross-sectional study enrolled patients who tested positive for COVID-19 with PCR via nasopharyngeal swabs. Conjunctival swabs were collected for each patient and subjected to RT-PCR assay.
Septoria tritici blotch (STB) of wheat, caused by the ascomycete (formerly ), is one of the most important foliar diseases of wheat. In Morocco, STB is a devastating disease in temperate wheat-growing regions, and the yield losses can exceed up to 50% under favorable conditions. The aims of this study were to identify sources of resistance to STB in Septoria Association Mapping Panel (SAMP), which is composed of 377 advanced breeding lines (ABLs) from spring bread wheat breeding program of ICARDA, and to identify loci associated with resistance to STB at seedling (SRT) as well as at the adult plant (APS) stages using genome-wide association mapping (GWAM).
View Article and Find Full Text PDFHybrid wheat breeding is one of the most promising technologies for further sustainable yield increases. However, the cleistogamous nature of wheat displays a major bottleneck for a successful hybrid breeding program. Thus, an optimized breeding strategy by developing appropriate parental lines with favorable floral trait combinations is the best way to enhance the outcrossing ability.

This genetic disease leads to a defective beta-globin hemoglobin chain causing partial or complete beta-globin chain synthesis loss. Beta-thalassemia major patients need a continuous blood transfusion and iron chelation to maintain the normal homeostasis of red blood cells (RBCs) and other systems in the body.

Nevertheless, small randomized controlled trials have failed to demonstrate a survival advantage. Thus, whether volatile anesthetics improve the postoperative outcome of cardiac surgical patients remains uncertain.
