Could veterinarians be immune to contracting SARS-CoV-2?

Introduction: The aim of the study was to assess the epidemic situation among veterinarians of the Świętokrzyskie Voivodeship, Poland, in relation to the control group.

Material And Methods: The research was divided into 3 stages. Stage I involved the selection of subjects.

A five-year follow up study of stage I-IV of rectal cancer with an emphasis on epidermal growth factor over-expression.

The key pro-proliferative pathway, based on EGFR-KRAS/BRAF-myc, is seen as the main goal of personalized therapy in rectal cancer. The objective of the study is to assess the EGFR immunoreactivity in rectal cancer and to estimate its relationship with the clinical outcome, especially as a predictor of poor outcomes. Patients: applying exclusion criteria, 102 patients with stage I-IV rectal cancer, who had undergone scheduled surgery during the period 2005-2011, were included in the study.

P21 is not a prognostic marker for rectal cancer - five-year follow up study of rectal cancer in stages I-IV.

The p21 participates in the regulation of DNA repair and replication, and modulation of apoptosis as well. After DNA damage, the p53-dependent induction of p21 results in cell cycle arrest or could trigger cell apoptosis. The objective of the study was the assessment of p21 immunoreactivity in rectal cancer and the estimation of relationships with clinical outcome especially as predictor of poor outcome.

Gastric gastrointestinal stromal tumor with incomplete duplication cyst - a case with possibility of neoplasia in fetal-period malformed tissues.

The coincidence of GIST and other gastric malignancies are documented well but arising GIST from congenital anomalies is still rarity in literature. To date, only a few papers have been concerned on the possibility of arising neoplasms from duplication cyst of gastrointestinal tract. There, are dominating usual cancers, neuroendocrine cancers or lymphomas but GIST has been noted only once.

[Clinical problems of extended intestinal resections].

Unlabelled: Extended intestinal resections constitute a primary surgical problem, and in numerous cases there is the necessity of programming an appropriate nutrition, including parenteral nutrition at patient's home. The aim of the work was to examine treatment problems: surgery indications, complications and the after-effects of extended intestinal resections as well as the procedure rules.

Materials And Methods: The group of 51 patients with extended intestinal resections who were subjected to treatment in the years 1988-2002.
