Ex-Vivo 3D Cellular Models of Pancreatic Ductal Adenocarcinoma: From Embryonic Development to Precision Oncology.

Pancreas is a vital gland of gastrointestinal system with exocrine and endocrine secretory functions, interweaved into essential metabolic circuitries of the human body. Pancreatic ductal adenocarcinoma (PDAC) represents one of the most lethal malignancies, with a 5-year survival rate of 11%. This poor prognosis is primarily attributed to the absence of early symptoms, rapid metastatic dissemination, and the limited efficacy of current therapeutic interventions.

[Confocal laser endomicroscopy in the diagnostics of esophageal diseases: a pilot study].

Background: Probebased confocal laser endomicroscopy (pCLE) is a novel diagnostic technique for endoscopy which enables a microscopic view at a cellular resolution in realtime. Endoscopic detection of early neoplasia in the distal esophagus is difficult and often these lesions can be missed. The aim of the pilot study was to obtain characteristic pCLE figures in esophageal diseases for following studies, and to evaluate the possible future role of pCLE in the diagnostics of dysplastic Barretts esophagus (BE) or early esophageal adenocarcinoma (EAC).

Distinct bacterial communities in tropical island aquifers.

The groundwater biome is a poorly characterized habitat hypothesized to harbor uniquely diverse bacterial communities; the degree to which these communities differ from associated soils is a central question in environmental microbiology. We characterized the Bacterial community composition in 37 aquifer and 32 surface soil samples across the island of O'ahu, Hawai'i. Several bacterial phyla (Acetothermia, Omnitrophica, Parcubacteria, Peregrinibacteria) relatively abundant in the aquifer samples were rare to absent in the soils.

The Use of Indocyanin Green for Peroperative Diagnostic of Chylous Ascites and Autologous Tissue Glue (Vivostat) for the Treatment.

Background: Chylous ascites or chyloperitoneum can be caused by peroperative injury of the lymphatic pathways; the lymph is accumulated in the abdominal cavity. The incidence of chylous ascites varies according to the type of surgery and the extent of the lymphadenectomy. The first choice of treatment is a conservative procedure - total parenteral nutrition or a strict low-fat diet.

Lymphomas and acute abdomen - a set of case reports.

Surgical treatment of gastrointestinal solid tumors is the basic method with a curative potential. However, the first-line treatment modalities in lymphomas are systemic oncology therapy (chemotherapy, immunotherapy and hematopoietic stem cell transplantation), radiotherapy or their combination. Surgery in lymphomas is predominantly associated with acute disease and dominantly, surgery is still used mainly in diagnosing lymphomas.
