Lymph Node and Bone Marrow Micrometastases Define the Prognosis of Patients with pN0 Esophageal Cancer.Pathological routine lymph node staging is postulated to be the main oncological prognosticator in esophageal cancer (EC). However, micrometastases in lymph nodes (LNMM) and bone marrow (BNMM) are discussed as the key events in tumor recurrence. We assessed the prognostic significance of the LNMM/BNMM status in initially pN0 staged patients with curative esophagectomy.

Detection of breast cancer lymph node metastases in frozen sections with a point-of-care low-cost microscope scanner.Detection of lymph node metastases is essential in breast cancer diagnostics and staging, affecting treatment and prognosis. Intraoperative microscopy analysis of sentinel lymph node frozen sections is standard for detection of axillary metastases but requires access to a pathologist for sample analysis. Remote analysis of digitized samples is an alternative solution but is limited by the requirement for high-end slide scanning equipment.

Concentrated growth factor exudate enhances the proliferation of human periodontal ligament cells in the presence of TNF‑α.The purpose of this study was to evaluate the effects of concentrated growth factor exudate (CGFe) on human periodontal ligament cells (hPDLCs) stimulated by tumor necrosis factor (TNF)‑α. From the peripheral blood of healthy donors, CGFe was prepared according to the Sacco protocol after 7 days of incubation. The hPDLCs were cultured by a tissue explant method and identified with anti‑vimentin and anti‑cytokeratin antibodies. Cells were subjected to four different treatments: i) Control; ii) TNF‑α (10 ng/ml); iii) CGFe (concentration 50%); and iv) CGFe+TNF‑α. The proliferation of hPDLCs was measured with Cell Counting Kit‑8 assays. Osteogenic differentiation and mineralization were determined by Alizarin Red S staining, alkaline phosphatase activity, western blotting and reverse transcription‑quantitative polymerase chain reaction. CGFe enhanced cell proliferation and upregulated ALP activity, the mineralization level, and osteogenic‑associated osteocalcin, runt‑related transcription factor 2 and Osterix gene expression in hPDLCs under inflammatory conditions induced by TNF‑α. The present study demonstrated that CGFe enhanced hPDLC proliferation and osteogenic differentiation in the presence of TNF‑α‑induced inflammation. As CGFe can be obtained from the venous blood of patients, it generates no immune reaction. Thus, it is more economical and beneficial to use CGFe in clinical periodontal regeneration practice than synthetic growth factors.

Platelet‑rich fibrin exudate promotes the proliferation and osteogenic differentiation of human periodontal ligament cells in vitro.The purpose of the present study was to evaluate the effects of platelet‑rich fibrin (PRF) exudate on the proliferation, osteogenic differentiation and mineralization of human periodontal ligament cells (hPDLCs) in vitro. In the present study PRF was obtained with permission, from the peripheral blood of healthy donors and PRF exudates were collected on the 7th day of incubation. hPDLCs were obtained from healthy premolars, cultured by a tissue explant method and identified with anti‑vimentin and anti‑cytokeratin antibodies. PRF exudates were added to hPDLCs in different concentrations to evaluate cell proliferation and osteogenic differentiation. The proliferation of hPDLCs was measured using a colorimetric assay. Osteogenic differentiation and mineralization were determined by Alizarin red staining, alkaline phosphatase activity (ALP), western blotting and reverse transcription‑quantitative polymerase chain reaction. Cell proliferation was enhanced by addition of the PRF exudate, which also promoted the formation of mineralized matrix nodules and upregulated ALP activity and osteoblast‑associated levels of osteocalcin, runt‑related transcription factor and osterix gene expression. As these stimulatory effects occurred in a dose‑dependent manner, it was concluded that high concentrations of the PRF exudate served an essential role in the proliferation, osteogenic differentiation and mineralization of hPDLCs in vitro. The present study demonstrated that PRF exudate enhanced hPDLC proliferation, induced the osteoblastic differentiation of hPDLCs into mineralized tissue‑formation cells in vitro, and may therefore provide potential beneﬁts for periodontal tissue engineering; contributing to the primary processes of periodontal tissue regeneration. From the perspective of both economics and biology, PRF has greater clinical benefits than analogous growth factors.

Free‑floating cancer cells in lymph node sinuses of hilar lymph node‑positive patients with non‑small cell lung cancer.Previous studies demonstrated that free‑floating cancer cells (FFCCs) in the lymph node sinuses were of prognostic significance for colorectal and gastric cancer. The present study investigated the clinical significance of detecting FFCCs using Fast Red staining for cytokeratin in stage I/II non‑small cell lung cancer (NSCLC) patients and hilar lymph node positive NSCLC patients who underwent curative resection. Between 2002 and 2011, a total of 164 patients (including 22 hilar lymph node positive patients) were investigated. Resected lymph nodes were stained for cytokeratin using an anti‑cytokeratin antibody. In order to achieve a clear distinction from coal dust, an anti‑cytokeratin antibody was labeled with a secondary antibody conjugated with alkaline phosphatase, which was detected by a reaction with Fast Red/naphthol that produced a red color. Patients were considered to be positive for FFCCs (FFCCs+) if one or more than one free‑floating cytokeratin‑positive cell was detected in the lymph node sinuses, which could not be detected by hematoxylin and eosin staining. Among all 164 patients, a significant difference was observed in 5‑year relapse‑free survival (5Y‑RFS) rates, with 76.9 and 33.3% being achieved by FFCCs‑ and FFCCs+ patients, respectively (P<0.001). Similarly, the 5‑year overall survival (5Y‑OS) rate was significantly lower in FFCCs+ patients, with 86.6% being achieved by FFCCs‑ and 65.8% by FFCCs+ patients, respectively (P=0.014). Among 22 hilar lymph node‑positive patients, a significant difference was also observed in 5Y‑RFS, with 53.8 and 0.0% being achieved by FFCCs‑ and FFCCs+ patients, respectively (P=0.006). The 5Y‑OS tended to be lower in FFCCs+ patients, with 69.2 and 53.3% being achieved by FFCCs‑ and FFCCs+ patients, respectively (P=0.463). The findings of the present study suggested the presence of FFCCs in stage I/II NSCLC patients was associated with a poor prognosis. In addition, FFCCs in hilar lymph node‑positive patients may potential be a useful marker in foreseeing the recurrence of cancer.

Three-dimensional evaluation of subclinical extension of extramammary Paget disease: visualization of the histological border and its comparison to the clinical border.In extramammary Paget disease (EMPD), Paget cells are sometimes detected outside the clinical border (subclinical extension). However, the spreading pattern of Paget cells in subclinical extension remains unclear. In addition, the macroscopic appearances of lesions accompanied by subclinical extension are totally unknown.

Changes in the sebaceous gland in patients with male pattern hair loss (androgenic alopecia).The sebaceous gland and the follicular bulge region have important role in biology of the hair. They initiate destruction of the hair follicle both in human and animal models in certain conditions. The morphometric feature of the sebaceous gland is not well understood so as the distribution of the bulge stem cells in pathological conditions of male pattern hair loss or androgenic alopecia (AGA).

Immunohistochemical expression of fibrillin-1 and fibrillin-2 during tooth development.Oxytalan fibers are categorized as a microfibril assembly without elastin deposition, and are unique components in the periodontal ligament (PDL). However, little is known about their formation during PDL development. To clarify the mechanisms of oxytalan fiber formation in developing PDL, we performed immunohistochemical analysis to detect the direct expression of fibrillin-1 and fibrillin-2, which are major components of microfibrils.
