Background: This study evaluated the safety and effectiveness of the cytomegalovirus (CMV) Specific Antigen Induced Interferon-Gamma ELISPOT (enzyme-linked immunosorbent spot)/ELISA (enzyme-linked immunosorbent assay) procedure in predicting the risk of CMV infection/disease in immunocompromised patients through a systematic literature review. Methods: The searched electronic databases included MEDLINE, EMBASE and the Cochrane Library. A total of 884 non-duplicate citations were retrieved and a total of 25 studies (15 cohort studies, 10 cross-sectional studies) were included in this review. Study subjects were selected among patients with solid organ, hematopoietic stem cell transplantation, or those who were on hemodialysis. Data extraction and literature quality assessment were carried out independently by two researchers. Results: Most of the studies were conducted on patients with solid organ transplants. As it is conducted outside the body, CMV Specific Antigen Induced Interferon-Gamma ELISPOT/ELISA assay was safe. Regarding its effectiveness, most studies on risk analysis based on prognosisrelated outcomes reported that the inactive group showed a significantly higher hazard ratio or odds ratio than the active group. Results of Kaplan-Meier survival analysis also showed that the inactive group had a significantly higher incidence of CMV event (CMV infection, CMV disease, other events) than the active group. However, various thresholds for CMV cell immune response were reported, as was a broad range of predictive diagnostic accuracies. Conclusion CMV Specific Antigen Induced Interferon-Gamma ELISPOT/ELISA assay has potential to stratify the risk of CMV infection/disease among solid organ transplant patients and to determine a policy for a prophylaxis/preemptive. However, additional literature evidence is needed to establish thresholds for CMV cell immune response and standardized tests.

Purpose: Fractional microneedle radiofrequency (FMR) systems are used to treat inflammatory acne and scarring. Nonetheless, few controlled studies have combined this treatment with the traditional ablative fractional laser (AFL). We aimed to assess the safety and efficacy of the combination of FMR and AFL versus AFL alone in treating acne and acne scars. Materials and Methods: In this 20-week, randomized, split-face study, 23 Korean patients with facial acne and acne scars underwent FMR and AFL treatments. One half of each patient’s face was randomly assigned to receive FMR+AFL, whereas the other half received AFL alone. Treatments were administered in three consecutive sessions at 4-week intervals. This study investigated the severity of inflammatory acne, acne scars, individual lesion counts, depressed scar volumes, as well as patient and physician satisfaction. In addition, five patients underwent skin biopsy, and sebum output was measured. Results: The FMR+AFL treatment demonstrated superior efficacy compared to AFL alone in terms of inflammatory acne and acne scar grading, lesion counts, and subjective satisfaction. The side effects were minimal and well-tolerated in both groups. Immunohistochemical findings from skin biopsy samples revealed that the application of FMR+AFL could induce an inhibitory effect on sebum secretion at the molecular level. Conclusion FMR combined with AFL is a well-tolerated and effective treatment modality for inflammatory acne and acne scarring.

BACKGROUND: Iron is essential for cell proliferation and viability. It has been reported that iron depletion by a chelator inhibits proliferation of some cancer cells. Deferasirox is a new oral iron chelator, and a few reports have described its effects on lymphoma cells. The goal of this study was to determine the anticancer effects of deferasirox in malignant lymphoma cell lines. METHODS: Three human malignant lymphoma cell lines (NCI H28:N78, Ramos, and Jiyoye) were treated with deferasirox at final concentrations of 20, 50, or 100 microM. Cell proliferation was evaluated by an MTT assay, and cell cycle and apoptosis were analyzed by flow cytometry. Western blot analysis was performed to determine the relative activity of various apoptotic pathways. The role of caspase in deferasirox-induced apoptosis was investigated using a luminescent assay. RESULTS: The MTT assay showed that deferasirox had dose-dependent cytotoxic effects on all 3 cell lines. Cell cycle analysis showed that the sub-G1 portion increased in all 3 cell lines as the concentration of deferasirox increased. Early apoptosis was also confirmed in the treated cells by Annexin V and PI staining. Western blotting showed an increase in the cleavage of PARP, caspase 3/7, and caspase 9 in deferasirox-treated groups. CONCLUSION: We demonstrated that deferasirox, a new oral iron-chelating agent, induced early apoptosis in human malignant lymphoma cells, and this apoptotic effect is dependent on the caspase-3/caspase-9 pathway.

OBJECTIVE: The aim of this study was to identify apoptosis-related genes of ovarian cancer cell lines following cisplatin treatment. METHODS: We used IC50 values and fluorescence-activated cell sorting analysis to compare cell death in 2 ovarian cancer cell lines, namely, SKOV-3 and OVCAR-3, upon treatment with cisplatin. Moreover, the change in transcriptional levels of apoptosis-associated genes was measured with a dendron-modified DNA microarray. RESULTS: The protein levels for the up-regulated genes in each cell line were validated to identify the molecules that may determine the cellular behavior of cisplatin resistance. Eight genes were over-expressed in the 2 cell lines. The cisplatin-induced up-regulation of DAD1 in transcriptional and protein levels contributed to the cisplatin resistance of OVCAR-3, and the up-regulation of FASTK and TNFRSF11A in SKOV-3 resulted in its higher sensitivity to cisplatin than that of OVCAR-3. CONCLUSION: In the present study, we have identified a set of genes responsible for apoptosis following cisplatin treatment in ovarian cancer cell lines. These genes may give information about the understanding of cisplatin-induced apoptosis in ovarian cancer.
