[A retrospective cohort study of the effect of zolendronic acid on mandibular bone optical density in cancer patients].

The Aim The Study: To analyze the density of the mandible in cancer patients during treatment with zoledronic acid.

Materials And Methods: A retrospective cohort study included 45 patients with cancer aged 26-81 years (average age 55±12.88 years), of whom 14 patients had bone metastases (=14) and took 4 mg of zolendronic acid once every 28 days.

Ultrafast Proton Conduction in an Aqueous Electrolyte Confined in Adamantane-like Micropores of a Sulfonated, Aromatic Framework.

Sulfonated, cross-linked porous polymers are promising frameworks for aqueous high-performance electrolyte-host systems for electrochemical energy storage and conversion. The systems offer high proton conductivities, excellent chemical and mechanical stabilities, and straightforward water management. However, little is known about mass transport mechanisms in such nanostructured hosts.

Transport Mechanism in Nafion Revealed by Detailed Comparison of H and O Nuclear Magnetic Resonance Diffusion Coefficients.

We use H and O NMR static field gradient diffusometry to measure self-diffusion coefficients of protons () and oxygens () in Nafion 212 with various hydration levels (λ = 4-18). For all samples and both nuclei, we obtain activation energies () of ≈0.19 eV.

[Undifferentiated pancreatic carcinoma with osteoclast-like giant cells].

In the structure of malignant oncological diseases of the Russian population, pancreatic cancer (PCa) occupies the 10th place with a high mortality rate in case of late diagnosis, which is primarily due to the minimal clinical manifestations of this pathology and the absence of precancer as a potential substrate for screening. Undifferentiated pancreatic carcinoma with osteoclast-like giant cell (UC-OGC) is a rare histological variant of PCa with discussed bidirectional histogenesis (epithelial and mesenchymal), epithelial-mesenchymal transition in the tumor and variable prognosis depending on the predominant cellular component. A review of the literature reflecting debatable issues of origin, clinical and pathological characteristics and prognosis of UC-OGC, as well as a description of a clinical case is relevant due to the rare occurrence of this tumor in the routine work of pathologists and oncologists.

Evaporation of Sessile Binary Mixture Droplets: Time Dependence of Droplet Shape and Concentration Profile from One-Dimensional Magnetic Resonance Microscopy.

Many technological applications like inkjet printing, coating, or cooling processes rely on the evaporation of sessile droplets. Regarding liquid mixtures, the understanding of the underlying physics is still incomplete and process optimization requires trial and error. Our main goal is to establish a novel method in this field, one-dimensional magnetic resonance microscopy, to investigate the evaporation of sessile binary mixture droplets in the microliter range.
