[Drug-induced cognitive impairment and dementia].

One of the reasons for the development or worsening of cognitive impairment (CI) may be the use of a number of drugs: non-steroidal anti-inflammatory drugs, antiarrhythmics, antidepressants, glucocorticosteroids, antitumor drugs and a number of others. The negative effect of drugs on cognitive functions is realized due to many pathophysiological mechanisms: disruption of hormonal regulation, decreased neuronal excitability, increased activity of gamma-aminobutyric acid receptors, decreased cerebral circulation, atrophic changes in the brain; many mechanisms have not been fully established. Risk factors for the development of drug-induced CIs are: old age or childhood, brain damage, chronic diseases, genetic factors, the patient's initial CI, polypharmacy, dose and duration of drug use, acute infectious diseases, metabolic disorders, dehydration, acute urinary retention, etc.

Sequence of Structural and Magnetic Phase Transitions in (NO)Mn(NO).

New nitrosonium manganese(II) nitrate, (NO)Mn(NO), has been synthesized and structurally characterized. In the temperature range of 45-298 K, the crystal is hexagonal (centrosymmetric sp. gr.

[Influence of early surgery and endoscopic interventions on the risk of infection in patients with pancreatic necrosis].

Objective: To prevent purulent-septic complications in patients with destructive pancreatitis.

Material And Methods: A cohort study included 488 patients with pancreatic necrosis: group 1 (=331) - active surgical strategy, group 2 (=157) - follow-up and therapy. We used binary logistic regression to predict purulent-septic complications.

A combination of organic and inorganic cations in the synthesis of transition metal nitrates: preparation and characterization of canted rectangular Ising antiferromagnet (PyH)CsCo(NO).

Pyridinium cesium cobalt nitrate, (PyH)CsCo(NO), obtained from a nitric acid solution crystallizes in the orthorhombic space group with unit cell parameters = 8.6905(14) Å, = 11.9599(18) Å, = 18.

Ising-like Magnetism in Quasi-Two-Dimensional Co(NO)·2HO.

The appearance of electrically neutral water molecules in the structure of cobalt dinitrate dihydrate, Co(NO)⋅2HO, drastically changes its magnetic properties as compared to its waterless counterpart, Co(NO). The title compound shows Ising-like behavior reflected in its thermodynamic properties. It experiences long-range antiferromagnetic order at = 20.
