Advances in Thermochemical Synthesis and Characterization of the Prepared Copper/Alumina Nanocomposites
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
This paper presents thermochemical synthesis of copper/alumina nanocomposites in a Cu-Al2O3 system with 1–2.5 wt.% of alumina and their characterization, which included: transmission electron microscopy: focused ion beam ...
Nondestructive optical method for plant overall health evaluation
(Taylor & Francis, 2021)
In vivo measurements of the optical properties of plant leaves, by spectrophotometric methods, could potentially provide very useful information for the assessment of the plant’s health. This paper describes a novel ...
Zinc Deficiency, Plasma Fatty Acid Profile and Desaturase Activities in Hemodialysis Patients: Is Supplementation Necessary?
(Frontiers Media, 2021)
Background: Desaturation and elongation are critical processes in endogenous metabolic fatty acid pathways. Zinc (Zn) is a cofactor for desaturases and elongases enzymes. There is limited evidence regarding the relationships ...
Impact of essential and toxic trace metals on thyroid health and cancer: A review
(Springer, 2021)
Most investigations conducted in the last four decades have shown a rising incidence of thyroid diseases worldwide. Although our knowledge of the molecular pathways of thyroid disease has advanced, the initial steps in ...
Macroporous monoliths based оn natural mineral sources, clay аnd diatomite
(Science of Sintering, 2020)
Macroporous silica ceramic was obtained using clay and diatomite. Boric acid as a low-cost additive in the amount of 1 wt% was used. These porous materials were obtained at low forming pressure (40-80 MPa) and lower sintering ...
Stacking interactions of resonance-assisted hydrogen-bridged rings and C6-aromatic rings
(Royal Society of Chemistry, 2020)
Stacking interactions between six-membered resonance-assisted hydrogen-bridged (RAHB) rings and C6-aromatic rings were systematically studied by analyzing crystal structures in the Cambridge Structural Database (CSD). The ...
Carbohydrate – Protein aromatic ring interactions beyond CH/π interactions: A Protein Data Bank survey and quantum chemical calculations
(Elsevier, 2020)
The geometries of the contacts between monosaccharides and aromatic rings of amino acids found in X-ray crystallography structures, in the Protein Data Bank (PDB), were analyzed, while the energies of the interactions were ...
Assessment of trace metal alterations in the blood, cerebrospinal fluid and tissue samples of patients with malignant brain tumors
(Nature Research, 2020)
The pathogenesis of malignant brain tumors (MBTs) should be better understood due to the evident association between prolonged exposure to metals and increased risk of MBTs. The present research aimed to find trace metals ...
The Significance of Reactive Oxygen Species and Antioxidant Defense System in Plants: A Concise Overview
(Frontiers, 2021)
In plants, there's a complex and multilevel network of the antioxidative system (AOS) operating to counteract harmful reactive species (RS), the foremost important of which are reactive oxygen species (ROS), and maintain ...
Significance of arsenic and lead in Hashimoto's thyroiditis demonstrated on thyroid tissue, blood, and urine samples
(Elsevier, 2020)
Our previous investigation showed significantly increased arsenic (As) content in thyroid tissue samples of patients with Hashimoto's thyroiditis (HT). This research aimed to extend previous findings and provide reliable ...
