Biobutanol production from underutilized substrates using : Unlocking untapped potential for sustainable energy development.

The increasing demand for sustainable energy has brought biobutanol as a potential substitute for fossil fuels. The genus is deemed essential for biobutanol synthesis due to its capability to utilize various substrates. However, challenges in maintaining fermentation continuity and achieving commercialization persist due to existing barriers, including butanol toxicity to , low substrate utilization rates, and high production costs.

Recombinant proteins production in BL21 for vaccine applications: a cost estimation of potential industrial-scale production scenarios.

Recent SARS-CoV-2 pandemic elevated research interest in microorganism-related diseases, and protective health application importance such as vaccination and immune promoter agents emerged. Among the production methods for proteins, recombinant technology is an efficient alternative and frequently preferred method. However, since the production and purification processes vary due to the protein nature, the effect of these differences on the cost remains ambiguous.

Regulatory consideration on preparation and clinical use of COVID-19 convalescent plasma.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the cause of coronavirus disease (COVID-19), spreading from Wuhan to worldwide has been emerged since December 2019. Although scientists and researchers have been racing to develop specific therapeutic agents or vaccines against SARS-CoV-2 since the identification of the agent, either a drug or a vaccine has not been approved to treat or to prevent COVID-19 up to date. On the base of historical experiences, Convalescent Plasma (CP), a passive antibody therapy, has been evaluated as a hopeful and potential therapeutic option since the beginning of the COVID-19 outbreak.

Medical safety reporting system neccessity and analysis of Turkey 2016 data: A health policy report.

Background: The National Safety Reporting System, which is developed for Turkey, aims to classify medical errors with a coding methodology that handles errors in subcategories. Error entries done via the system are added to the statistics immediately by advanced live data reporting capabilities of the software.

Objective: Our aim was to provide information about the Turkey local reporting system to ensure patient safety by detecting medical errors.

Alkaline Hydrothermal Synthesis, Characterization, and Photocatalytic Activity of TiO₂ Nanostructures: The Effect of Initial TiO₂ Phase.

One-dimensional (1D) titanate nanostructures were synthesized by hydrothermal route, using commercially available TiO₂ (P25) and anatase powders as precursor materials and strong NaOH solution as catalyzer. The prepared titanates were calcined, followed by protonation to produce TiO₂ nanostructures having enhanced photocatalytic and photovoltaic properties. The synthesized TiO₂ 1D nanostructures were characterized using field-emission scanning electron microscope, high-resolution electron microscope, X-ray diffraction analysis, and UV-Vis photospectroscopy to understand the effect of initial TiO₂ phase on morphological and crystallographic features, and bandgap.

Characterization study and optimization of swelling behavior for p(HEMA-co-Eudragit L-100) hydrogels by using Taguchi Method.

The aim of this study is to produce the smart hydrogel to use insulin release for human body. p(HEMA-co-Eudragit L-100) hydrogels containing different ratios of 2-Hydroxyethyl methacrylate (HEMA) and Eudragait L-100 were synthesized by using ammonium persulfate (APS) as an initiator and ethylene glycol dimethacrylate (EGDMA) as a cross linker. The structures of hydrogels produced were characterized by using Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning electron microscope (SEM) analysis.

Facile synthesis of CsPbBr/PbSe composite clusters.

In this work, CsPbBr and PbSe nanocomposites were synthesized to protect perovskite material from self-enlargement during reaction. UV absorption and photoluminescence (PL) spectra indicate that the addition of Se into CsPbBr quantum dots modified the electronic structure of CsPbBr, increasing the band gap from 2.38 to 2.

Anxiety and depression in patients with rheumatoid arthritis.

Rheumatoid arthritis (RA) mostly follows a painful, progressively disabling course, and individuals with RA experience more psychological distress than healthy individuals. The objective of the present study is to examine the prevalences of accompanying anxiety and depression in RA cases. The study included 82 RA cases and 41 age- and sex-matched healthy volunteers as the control group.

Strict volume control can improve structure and function of common carotid artery in hemodialysis patients.

Background: Damage in large arteries, characterized by increased intima-media thickness and decreased compliance, is frequent in hemodialysis patients and increases cardiovascular morbidity and mortality. Since volume overload and hypertension may accelerate atherosclerosis in patients with chronic renal failure, the aim of this 1-year study was to assess whether strict volume control would improve structural and functional abnormalities of the com-mon carotid artery in hypertensive hemodialysis patients.

Methods: We conducted a prospective study (n=16) for 1 year to investigate the effect of strict volume control on intima-media thickness and compliance of the common carotid artery.
