Integrated miRNA Signatures: Advancing Breast Cancer Diagnosis and Prognosis.

Breast cancer ranks first in incidence and second in deaths worldwide, presenting alarmingly rising mortality rates. Imaging methodologies and/or invasive biopsies are routinely used for screening and detection, although not always with high sensitivity/specificity. MicroRNAs (miRNAs) could serve as diagnostic and prognostic biomarkers for breast cancer.

Clinical, Histopathological, and Immunohistochemical Characteristics of Predictive Biomarkers of Breast Cancer: A Retrospective Study.

Background/aim: Breast cancer is a complex disease with variability in clinical manifestation, response to current therapy, and biochemical and histological features among various subgroups. Histologic grading and immuno-histochemical evaluation of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2), and Ki-67 proliferation index play a crucial role in increasing the differential diagnostic value among various types of breast carcinoma. The aim of this study was to determine the histopathological and immuno-histochemical characteristics of breast tumors from a University Laboratory of Pathology in Greece.

Unravelling the Role of P300 and TMPRSS2 in Prostate Cancer: A Literature Review.

Prostate cancer is one of the most common malignant diseases in men, and it contributes significantly to the increased mortality rate in men worldwide. This study aimed to review the roles of p300 and TMPRSS2 (transmembrane protease, serine 2) in the AR (androgen receptor) pathway as they are closely related to the development and progression of prostate cancer. This paper represents a library-based study conducted by selecting the most suitable, up-to-date scientific published articles from online journals.

Experiential student study groups: perspectives on medical education in the post-COVID-19 period.

Background: Undergraduate medical curricula often fail to integrate experiential learning methodologies. Thus, a pilot series of interactive pathology lessons was designed and implemented in an attempt to promote experiential learning.

Methods: Thirty pre-graduate medical students voluntarily participated in the interactive study groups at the First Department of Pathology of the National and Kapodistrian University of Athens, Medical School.

Asynchronous E-learning after synchronous E-learning in the pathology course. When is the proper time for this transition?

Background: Recordings of live streaming e-lessons of pathology at medical school of National and Kapodistrian University of Athens, Greece are uploaded to the e-class portfolio of each student enrolled in the course. We measured the number of views each video received and noticed that this number exceeded the number of enrolled students. Our main aim was to investigate the correlation between the upload of an educational video and the views it got so as to determine when the proper time is for professors to e-share or upload an educational video for the students.

Primary thyroid teratoma in adults: A case report and systematic review of the literature.

Extragonadal germ cell tumors are uncommon in adults and only 2-5% of teratomas develop in extragonadal sites. Primary thyroid teratomas represent <0.1% of all primary thyroid gland neoplasms.

Impact of PD-L1 Protein Expression on Renal Cell Carcinoma Histo-differentiation.

Background/aim: Renal cell carcinoma (RCC) comprises a variety of pathological entities. Many RCCs are aggressive, demanding efficient targeted and immunetherapeutic strategies. Programmed cell death ligand-1 (PD-L1) is expressed mainly in hematopoietic cells and also in epithelial cells.

Correlation between LGR5 stem cells and location of tumor as well as age, sex and metastasis in colon adenocarcinoma.

Purpose: G-protein receptors belong to a large family of receptors which includes more than 800 kinds. An interest for these receptors arose upon noticing their expression on skin, intestine and breast stem cells.

Methods: We examined the tissues of 53 patients who had been diagnosed with adenocarcinoma of the colon.

Prognostic value of average home blood pressure and variability: 19-year follow-up of the Didima study.

Objective: The current general population study explored the prognostic value of home blood pressure (HBP) average and variability (BPV) versus office measurements (OBP).

Methods: In 1997, 665 adults of Didima, Argolida, Greece were evaluated with OBP (two visits, six readings) and HBP (3 days, 12 readings) measurements. Total mortality and cardiovascular morbidity and mortality (CVD) were assessed after 19.

Immunohistochemical investigation of angiogenic factors in parathyroid proliferative lesions.

Objective: The pathological distinction between parathyroid neoplasms and hyperplasias remains difficult in several cases. Endoglin (CD105) is a proliferation-associated and hypoxia-inducible protein abundantly expressed in angiogenic endothelial cells. Vascular endothelial growth factor (VEGF) induces angiogenesis and VEGF-R2 is a tyrosine kinase receptor expressed early in development by endothelial cell precursors.

ICAM-1 and beta(3) integrin immunoexpression in malignant melanoma cells: can they be used as additional predictors?

Malignant melanoma usually progresses from the intraepidermal microenvironment through a distinct radial growth phase, in which malignant potential cannot always be accurately evaluated, to invasion of the dermis (vertical growth phase) and metastasis. During these stages malignant cells interact with each other and with the extracellular matrix. This interaction is mediated by cell surface adhesion molecules such as the beta(3) integrin subunit and ICAM-1.

A comparative study of the int-2 gene product in primary and secondary parathyroid lesions.

Objective: The family of fibroblast growth factors stimulates proliferation of cells of mesenchymal, epithelial and neuroectodermal origin. One of the members of this family, the product of proto-oncogene int-2, fibroblast growth factor-3, has been found to stimulate mitosis of parathyroid cells in culture. Primary and secondary hyperparathyroidism have no clear differences with regard to the histopathological features of the diseased parathyroid glands.
