The effects of sleep deprivation on the balance system: following normal sleep, 24 h of sleep deprivation, and rest under eyes-open and eyes-closed conditions.

Objective: This study investigated the effects of sleep deprivation (SD) on balance after normal sleep, 24 h of SD, and subsequent rest under eyes-open (EO) and eyes-closed (EC) conditions. Our aim was to ascertain whether the reduced efficiency of balance control following SD is generalized or selective.

Method: Nineteen participants (12 females, 7 males) completed the Pittsburgh Sleep Quality Index (PSQI).

Enhancing visible light photocatalytic activity of holmium doped g-CN and DFT theoretical insights.

In the search of novel photocatalysts to increase the effect of visible light in photocatalysis, g-CN (CN) has become a shining star. Rare earth metals have been used as dopant material to reinforce the photocatalytic activity of CN due to their unique electron configuration recently. In this present study, the pure and different amounts of Ho-doped g-CN (HoCN) photocatalysts were successfully synthesized using urea as a precursor by the one-pot method.

Recent advances and applications of nanostructured membranes in water purification.

In recent years, water pollution caused by hazardous materials such as metals, drugs, pesticides, and insecticides has become a very serious environmental and health problem that needs to be addressed urgently. The nutritional needs associated with the increasing population also increase the demand for water use and rapidly increase the rate of freshwater consumption. Since most of the water in the universe is in the form of sea water, which cannot be directly used, freshwater resources are limited, compared to the existing available water.

The effect of acute and chronic formaldehyde exposure on learning and memory in male and female rats.

Aim: Formaldehyde is a chemical that lies behind the various systemical failures in organism. Many products that people use contain formaldehyde. Owing to its tissue fixative properties, scientists who work in life sciences are exposed to this substance more than others.

Global disparities in patients with multiple myeloma: a rapid evidence assessment.

There are disparities in outcomes for patients with multiple myeloma (MM). We evaluated the influence of sociodemographic factors on global disparities in outcomes for patients with MM. This rapid evidence assessment (PROSPERO, CRD42021248461) followed PRISMA-P guidelines and used the PICOS framework.

Assesment of the patients presenting with severe anemia to the emergency internal medicine clinic.

Objective: Etiological evaluation of the patients who were hospitalized with the diagnosis of severe anemia (Hb<7 gr/dl) in the emergency internal medicine clinic between January and July, 2013.

Methods: In this study, 112 patients who were hospitalized in Dr. Lutfi Kirdar Kartal Education and Research Hospital emergency internal medicine clinic with severe anemia between January and July 2013 were retrospectively analyzed.

Trace metals in tissues of the six most common fish species in the Black Sea, Turkey.

Concentrations of Mn, Fe, Co, Ni, As, Se, Cd, Ag and Pb in scale, skin, muscle, gills, liver and the gonads of Gilthead seabream (Sparus aurata), European seabass (Dicentrarchus labrax), Black Sea salmon (Salmo trutta labrax), Horse mackerel (Trachurus trachurus), Red mullet (Mullus barbatus) and Whiting (Merlangius merlangius euxinus) from the Black Sea, in Turkey, were investigated. Elemental analyses were performed with inductively coupled plasma-mass spectrometry after sample preparation by microwave digestion. Mean metal concentrations in different tissues were in the following ranges: Mn 0.

Effect of digitizing techniques on the fit of implant-retained crowns with different antirotational abutment features.

Statement Of Problem: The development of computer-aided design/computer-aided manufacturing technology has enabled the fabrication of implant-retained restorations. However, information on the marginal and axial accuracy of restorations fabricated by different digitizing techniques with different antirotational abutment features is not sufficient.

Purpose: The purpose of this in vitro study was to evaluate the influence of digitizing techniques on the fit of implant-retained crowns with 2 antirotational features.

Human IL2RA null mutation mediates immunodeficiency with lymphoproliferation and autoimmunity.

Cell-surface CD25 expression is critical for maintaining immune function and homeostasis. As in few reported cases, CD25 deficiency manifests with severe autoimmune enteritis and viral infections. To dissect the underlying immunological mechanisms driving these symptoms, we analyzed the regulatory and effector T cell functions in a CD25 deficient patient harboring a novel IL2RA mutation.

The comparative effects of gene modulators on thyroid-specific genes and radioiodine uptake.

The aim of this study was to comparatively investigate the effects of 5-azacytidine-C (5-Aza), trichostatin-A (TSA), and all-trans retinoic acid (ATRA) on the mRNA expressions of the sodium and iodine (Na/I) symporter (NIS), thyroglobulin (Tg), thyroid peroxidase (TPO), and the thyroid-stimulating hormone receptor (TSH-R), as well as radioiodine (RAI) uptake in cancer (B-CPAP) and normal (Nthy-ori 3-1) thyroid cell lines. Cell lines were treated with 10 ng/mL of TSA, 5 microM of 5-AZA, and 1 microM of ATRA, according to the MTT (methyl-thiazol-tetrazolium) test results. Additionally, recombinant thyroid-stimulating hormone (rTSH) was also applied, with a selected dose of 100 ng/mL.
