Outcomes of the Paul Glaucoma Implant in Refractory Secondary Glaucoma.

Purpose: To evaluate the efficacy and safety of the Paul Glaucoma Implant (PGI) surgery in patients with secondary glaucomas.

Patients And Methods: Retrospective chart review of adult patients with medically recalcitrant secondary glaucoma who underwent PGI implantation at a single tertiary center between August 2022 and June 2023. The primary outcome measure was surgical success.

Phylogenetic and lipid metabolic differences between migratory and Egyptian-domesticated Mallard ducks (Anas platyrhynchos).

Although a giant Egyptian domestic non-migratory duck breed is phenotypically identical to the migratory Mallard, yet it is three times larger. The current study sought to determine the genetic and metabolic differences between this duck and Mallard, which arrives in Egypt in September for wintering and departs in March. Mitochondrial DNA control region (D-loop) was extracted, amplified, sequenced, and analyzed in both ducks.

Effective removal of As from aqueous medium using date palm fiber biochar/chitosan/glutamine nanocomposite: kinetic and thermodynamic studies.

In the current work, three adsorbent materials were developed: biochar derived from date palm fiber (C), date palm fiber biochar/chitosan nanoparticles (CCS), and biochar/chitosan nanoparticle composite supplemented with glutamine (CCSG). These compounds were used as solid adsorbents to remove As from polluted water. Several characterization approaches were used to investigate all the synthesized solid adsorbents, including thermogravimetric analysis, N adsorption/desorption isotherm, scanning electron microscopy, transmission electron microscopy (TEM), attenuated total reflectance with Fourier transform infrared, and zeta potential.

Molecular cloning, sequencing, expression and purification of Alkhumra hemorrhagic fever virus capsid protein in Saudi Arabia.

Introduction: Alkhumra hemorrhagic fever virus (AHFV) is a newly discovered virus in the Flaviviridae family. It was discovered in 1995 among animal handlers in Saudi Arabia. AHFV spreads through close contact with infected animals and tick bites.

Exploring risk factors for all-cause hospital readmissions following chronic obstructive pulmonary disease exacerbation patients discharged on steroid tapers.

Background: Chronic obstructive pulmonary disease (COPD) exacerbations often lead to hospitalizations and subsequent readmissions. Steroid therapy is a common approach in managing COPD exacerbations, yet a considerable proportion of patients experience readmissions within a short timeframe, highlighting the persistent and complex nature of COPD exacerbations. The aim of this retrospective study is to investigate risk factors for all-cause hospital readmissions in COPD patients discharged on steroid tapers following exacerbations, emphasizing the need for personalized management strategies to reduce readmission rates.
