Spermatocytic tumor: A rare case report.

Background: Spermatocytic tumor is a rare, malignant neoplasm of the testes. Since the prognosis for this tumor type is favorable, accurate diagnosis and differentiation from other malignant testicular neoplasms (classic seminoma and lymphoma) are crucial. To add to the existing literature on the diagnosis of spermatocytic tumor, herein we report the detailed clinical and histopathologic findings for a case that we encountered.

Ultrastructure of gap junction and Cx43 expression in gastric cancer tissues of the patients.

Introduction: Gap junctions are intercellular channels formed by connexin facilitating communication between cells by allowing transfer of ions and small signaling molecules. Connexin 43 (Cx43) is the most ubiquitous connexin in human tissues. Ample evidence suggests the role of gap junction and its connexins such as connexin 43 in human cancers including gastric cancer, which has an important place in the worldwide incidence of cancer and cancer-related deaths.

[RP-HPLC fingerprint of milk Stellera chamaejasme].

Objective: To establish a RP-HPLC fingerprint of milk Stellera chamaejasme.

Methods: The gradient elution mode was applied in chromatographic separation, and data were analysed by "Computer Aided Similarity Evaluation" software to compare the quality of milk Stellera chamaejasme samples from different habitats.

Results: Samples from different habitats were of high similarity, and analysied milk Stellera chamaejasme chromone and E15 in the atlas.
