[Advisability of carotid endarterectomy in asymptomatic patients].

Objective: To determine the optimal treatment strategy for patients with asymptomatic carotid stenosis.

Material And Methods: The authors reviewed clinical guidelines for the management of patients with asymptomatic carotid stenosis 60-99%, as well as medical studies and meta-analyses comparing carotid endarterectomy and optimal drug therapy in asymptomatic patients between 1993 and 2023.

Results: The choice of treatment strategy for patients with asymptomatic carotid artery stenosis is still a controversial issue.

Studies of the Antitumor Activity of Iodacetate in the Liposomal Form.

Metabolic reprogramming has become the new hallmark of cancer. Carbohydrate metabolism is a key component of metabolic transformations in tumors. To date, many therapeutic agents have been identified that target proteins and enzymes involved in glucose transport and metabolism, with promising results in cell culture studies and animal tumor models.

[Long-term safety and efficacy of trospium chloride for the treatment of neurogenic overactive bladder due to Parkinson's disease is there an effect on cognitive status?].

Aim: To evaluate the efficiency of long-term use of trospium chloride (Spazmex) for the treatment of patients with neurogenic overactive bladder due to Parkinson's disease (PD) and to determine the influence of therapy on the cognitive status of patients.

Materials And Methods: 60 patients with PD and neurogenic overactive bladder with stages 2.5, 3 and 4 according to Hoehn-Yahr scale were included in the main group.

Synchrotron single-crystal XRD, IR-, Raman spectroscopy and high pressure study of synthetic krieselite.

Spontaneous crystals of krieselite (Ge analogue of topaz) with the chemical formula Al[(GeSi)O](FOH) were synthesized using a thermo-gradient hydrothermal method at a temperature of 600/650 °C and pressure of 100 MPa. The unit cell parameters are: a = 8.9732(8) Å, b = 8.

Reversible Sorptive Preconcentration of Noble Metals Followed by FI-ICP-MS Determination.

In this paper, we propose the combined procedure of noble metal (NM) determination, including fire assay, acid digestion, and reversible dynamic sorptive preconcentration, followed by flow-injection ICP-MS. Reversible preconcentration of all NMs was carried out using micro-column packed new PVBC-VP sorbent and elution with a mixture of thiourea, potassium thiocyanate, and HCl, which recovers Pd, Ir, Pt, and Au by 95% and Ru, and Rh by 90%. The proposed procedure was approved using certified reference materials.
