Proliferation, apoptosis and expression of matrix metalloproteinase-9 in human fetal lung.

Expression pattern of the Ki-67, caspase-3 and matrix metalloproteinases-9 (MMP-9) factors were immunohistochemically analyzed in 48 human fetal lungs from 12 to 40 weeks of gestation. The number of Ki-67 positive cells in the epithelium of canaliculare (88cells/mm(2)) and sacculare stage (93cells/mm(2)) were significantly higher than in the epithelium of pseudoglandular stage (12cells/mm(2)) (p=0.0008 vs.

Co-expression of TTF-1 and neuroendocrine markers in the human fetal lung and pulmonary neuroendocrine tumors.

The expression pattern of thyroid transcription factor 1 (TTF-1) and neuroendocrine markers, neuron cell adhesion molecule (NCAM; CD56), chromogranin A (CgA) and synaptophysin (Syp), of different lung cell lineages was histologically analyzed in 15 normal human fetal lungs and 12 neuroendocrine tumors (NETs) using immunohistochemical methods. During pseudoglandular phase strong nuclear TTF-1 staining was detected in the columnar nonciliated epithelial cells, while NCAM, CgA and Syp had a moderate expression in the proximal airways and mild expression in the distal airways. Neuroendocrine cells (NECs) in proximal lung airway were co-localizing TTF-1 and other neuroendocrine markers while neuroendocrine bodies (NEBs) exhibit only staining with NCAM and Syp.

Antisperm antibodies and testicular blood flow after inguinal hernia mesh repair.

Background: Testicular flow studies after hernia mesh repair mostly showed different outcomes. The reason of infertility in some men after hernia repair is immunological factors. Aim of the study was to investigate the influence of mesh hernia repair on antisperm antibodies production and testicular blood flow and a connection among these parameters.

Peutz-Jeghers syndrome complicated with intussusception: enteroscopic polyps resections through laparotomy.

Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by intestinal hamartomatous polyps in association with mucocutaneous pigmentations. Here we present a case of a 30-year-old woman who was hospitalized and underwent diagnostic procedures because of crampy abdominal pain. Physical examination on admission revealed pigmented spots around lips and on the oral mucosa.

Influence of inguinal hernia mesh repair on testicular flow and sperm autoimmunity.

Background: The incidence of infertility caused by the mesh inguinal hernia repair is not known. The aim of this study was to determine circulation and immunological testicular disorders after inguinal hernia mesh repair which can be related with infertility.

Methods: From February 2010 to December 2010, 43 male patients who underwent inguinal hernia mesh repair were included in a prospective study.
