Unleashing the antitumor power of cyclophosphamide by arabinogalactan and aptamer conjugation.

Cyclophosphamide (CPA) (2-oxo-2-di(β-chloroethyl)amino tetrahydro-2,1,3-phosphoxazine) is an alkylating cytostatic compound with a broad spectrum of antitumor activity. Despite its efficacy, the clinical application of CPA is hindered by the significant occurrence of adverse side effects. To address these limitations, a promising approach involves the mechanochemical treatment of CPA with arabinogalactan (AG) to facilitate the dispersion of the drug within the AG matrix.

[Comparative assessment of the state of the cornea after YAG-laser interventions on anterior segment structures].

Unlabelled: YAG-laser interventions are associated with the risk of complications, including in the cornea.

Purpose: This study evaluates the condition of the cornea after laser discission (LD) of secondary cataracts (SC) and laser iridectomy (LI) using corneal confocal microscopy (CCM).

Material And Methods: Group 1 included patients with the diagnosis "Pseudophakia, secondary cataract", they underwent LD of SC.

Prg4-Expressing Chondroprogenitor Cells in the Superficial Zone of Articular Cartilage.

Joint-resident chondrogenic precursor cells have become a significant therapeutic option due to the lack of regenerative capacity in articular cartilage. Progenitor cells are located in the superficial zone of the articular cartilage, producing lubricin/Prg4 to decrease friction of cartilage surfaces during joint movement. Prg4-positive progenitors are crucial in maintaining the joint's structure and functionality.

Flexible Embedded Metal Meshes by Sputter-Free Crack Lithography for Transparent Electrodes and Electromagnetic Interference Shielding.

A facile and novel fabrication method is demonstrated for creating flexible poly(ethylene terephthalate) (PET)-embedded silver meshes using crack lithography, reactive ion etching (RIE), and reactive silver ink. The crack width and spacing in a waterborne acrylic emulsion polymer are controlled by the thickness of the polymer and the applied stress due to heating and evaporation. Our innovative fabrication technique eliminates the need for sputtering and ensures stronger adhesion of the metal meshes to the PET substrate.

[Particularities of arterial stiffness dynamics on the background of breast cancer chemotherapy].

Background: Modern breast cancer chemotherapy regimens (BC) consider individual patient parameters and ranges of cardiotoxic doses. However, clinicians often record clinical and laboratory-instrumental signs of cardio- and vasculotoxicity in patients, which emphasizes the high importance of searching for markers of early toxic response.

Aim: To study the characteristics of the response of arterial stiffness on the background of anthracycline-containing chemotherapy to determine potential markers of vasculotoxicity in BC patients.
