A Colorectal Cancer 3D Bioprinting Workflow as a Platform for Disease Modeling and Chemotherapeutic Screening.

Colorectal cancer (CRC) is the third most common malignancy and has recently moved up to the second leading cause of death among carcinomas. Prognosis, especially for advanced diseases or certain molecular subtypes of CRC, remains poor, which highlights the urgent need for better therapeutic strategies. However, currently, as little as 0.

Refractive index investigation of poly(vinyl alcohol) films with TiO2 nanoparticle inclusions.

The refractive index (RI) of polymer nanocomposite of poly(vinyl alcohol) films with TiO(2) nanoparticle inclusions with low concentration up to 1.2 wt. % was investigated.

[Changes in the gastric mucosa of ulcer patients with a reflux syndrome].

To 254 patients with active peptic ulcer 302 esophageal and 438 gastric endoscopic biopsies were performed and studied histologically. The patients were classified into 2 groups with and without (control group) reflux syndrome. The histological examination established atrophic changes in the antral mucosa in 58.

[Actinomycosis of the liver].

A case of a 61-years-old man, diabetic, drinking systematically, with primary liver actinomycosis is presented. The clinical course was that of septic cholangiohepatitis leading to liver and renal failure and death of infectious-toxic shock. The diagnosis was proved at autopsy.

[Current aspects of the diagnosis and surgical treatment of reflux esophagitis].

For a period of 18 months (1986-1987) a total of 2595 fiber gastroscopies have been performed for different reasons. Reflux esophagitis (RE) was visualized in 436 of the patients undergone fiber gastroscopy (16.8 per cent), histologically verified in 64.
