A comprehensive immunohistochemistry with the isoform-distinguishable antibodies against prostaglandin (PG) F2α and PGE2 biosynthetic enzymes was undertaken to identify the cellular types and enzyme isoforms in rat ovary and uterus around parturition. In general ovarian and uterine cells showed positive immunoreactions for phospholipase A2 groups 4A and 6A, but not group 2A, and cyclooxygenase (COX)-1 rather than COX-2. Their immunoreactions for PGF2α synthase and PGE2 synthase were cell type-dependently variable. The putative PGF2α and PGE2 producing cell types included, as expected, ovarian luteal cells, uterine endometrial epithelium and myometrium, and cervical connective tissue and, unexpectedly, ovarian stromal cells and basal lamina of cervical endometrium. Obtained data indicate the generation of PGF2α and PGE2 by multiple sites, which are entirely the same as established sites of actions, in parturition processes and tissue-dependent differential usage of PG biosynthetic pathway.

Chitinase 3-like protein 1 (CHI3L1) is emerging as a promising biomarker for assessing intracranial lesion burden and predicting prognosis in traumatic brain injury (TBI) patients. Following experimental TBI, Chi3l1 transcripts were detected in reactive astrocytes located within the pericontusional cortex. However, the cellular sources of CHI3L1 in response to hemorrhagic contusions in human brain remain unidentified.

Cytomegalovirus (CMV) pneumonia is an uncommon presentation of CMV among patients with HIV/AIDS, particularly in co-infection with pneumonia (PCP). A case was reported with a literature review, and a comprehensive literature search was performed using the PubMed/MEDLINE and Scopus databases. We report a 52-year-old male with AIDS presenting with progressively worsening dyspnea over 1 week.

Background: Robot-assisted thoracic surgery has been shown to have several advantages over conventional surgery. As mobile communication technology and surgical robotic devices in China continue to progress rapidly, the conditions for performing remote surgery have been optimized. Consequently, informatized and remote advanced medical cooperation is becoming a new direction for supporting the medical development of border regions and promoting the equitable distribution of medical resources in China.

Background: Pancreatic ductal adenocarcinoma (PDAC) is predicted to be the second leading cause of cancer-related death by 2030. This is driven by a high case-fatality rate with most patients even with radiologically localized PDAC at diagnosis ultimately relapsing with metastatic disease. mutations present in 90% to 95% of PDAC drive these poor statistics through its role in driving cellular growth, inhibition of apoptosis, and immunosuppression.
