Prevalence of Poor Sleep Quality Among Physicians During the COVID-19 Pandemic.

Background: Sleep quality is influenced adversely or favorably by various intrinsic and extrinsic factors and sleep deprivation is a common problem facing doctors.

Objectives: To assess sleep quality among physicians during coronavirus disease 2019 (COVID-19) pandemic and correlate it with possible predictors.

Methods: This cross-sectional four-months study included a total of 344 physicians from different medical centers in the period between July 2020 and October 2020, during the COVID-19 pandemic.

The Prevalence and Predictors of Post-Stroke Depression and Anxiety During COVID-19 Pandemic.

Introduction: Stroke is associated with a rise in post-stroke depression (PSD) and anxiety (PSA). In this study, we evaluated the impact of COVID-19 pandemic on the rates of PSD and PSA.

Methods: All stroke admissions to two hospitals in Saudi Arabia during two months were prospectively evaluated for PSD and PSA.

The Impact of Renal Tissue Procurement at Bedside on Specimen Adequacy and Best Practices.

Objectives: Renal biopsy is the gold standard for the diagnosis of both native and allograft renal diseases. We studied the impact of tissue procurement at bedside (TPB) omission on the adequacy of renal biopsies.

Methods: We compared 120 renal biopsies collected during 2015 using TPB with 111 renal biopsies collected during 2016 when TPB was discontinued.

Platelet-Rich Plasma Fat Graft versus Cartilage Perichondrium for Repair of Medium-Size Tympanic Membrane Perforations.

Objectives: To compare clinical and audiologic outcomes among patients who underwent myringoplasty with fat graft enriched with platelet-rich plasma and cartilage perichondrium graft.

Study Design: Prospective randomized controlled study.

Setting: Department of Otolaryngology-Head and Neck Surgery, Tanta University, Egypt.

UDP-galactose transporter gene hUGT1 expression in tobacco plants leads to hyper-galactosylated cell wall components.

We reported previously that tobacco plants transformed with the human UDP-galactose transporter 1 gene (hUGT1-transgenic plants) displayed morphological, architectural, and physiological alterations, such as enhanced growth, increased accumulation of chlorophyll and lignin, and a gibberellin-responsive phenotype. In the present study, we demonstrated that hUGT1 expression altered the monosaccharide composition of cell wall matrix polysaccharides, such as pectic and hemicellulosic polysaccharides, which are biosynthesized in the Golgi lumen. An analysis of the monosaccharide composition of the cell wall matrix polysaccharides revealed that the ratio of galactose to total monosaccharides was significantly elevated in the hemicellulose II and pectin fractions of hUGT1-transgenic plants compared with that of control plants.

The impact of the overexpression of human UDP-galactose transporter gene hUGT1 in tobacco plants.

When the human UDP-galactose transporter 1 gene (hUGT1) was introduced into tobacco plants, the plants displayed enhanced growth during cultivation, and axillary shoots had an altered determinate growth habit, elongating beyond the primary shoots and having a sympodial growth pattern similar to that observed in tomatoes at a late cultivation stage. The architecture and properties of tissues in hUGT1-transgenic plants were also altered. The leaves had an increase in thickness, due to an increased amount of spongy tissue, and a higher content of chlorophyll a and b; the stems had an increased number of xylem vessels and accumulated lignin and arabinogalactan proteins (AGPs).
