Balloon aortic valvuloplasty (BAV) is a treatment for high risk patients with severe aortic valve stenosis (AS). Rapid pacing is needed to reduce cardiac output when dilating the balloon, but it may cause cardiac ischemia or lethal arrhythmia. In this case report, percutaneous cardiopulmonary support (PCPS) was used to prevent these complications with BAV. We achieved adequate blood pressure and cardiac output during BAV without using rapid pacing by drawing a certain amount of blood into the reservoir equipped with the PCPS circuit. When performing BAV, PCPS may be a useful option for the patients who have high risks of circulatory failure.
3.Salicylamide Enhances Melanin Synthesis in B16F1 Melanoma Cells
Biomolecules & Therapeutics 2021;29(4):445-451
Salicylamide, a non-steroidal anti-inflammatory drug (NSAID), is used as an analgesic and antipyretic agent. We have previously shown that several NSAIDs have anti-melanogenic properties in B16F1 melanoma cells. In contrast, we have found that salicylamide enhances melanin contents in B16F1 melanoma cells; however, the underlying mechanism is not known. Therefore, we investigated the mechanism through which salicylamide stimulates melanogenesis. Interestingly, salicylamide enhanced diphenolase activity in a cell-free assay. Western blotting and real-time RT-PCR revealed that salicylamide increased tyrosinase expression via transcriptional activation of the Mitf gene. Together, our results indicate that salicylamide could be used as an antihypopigmentation agent for skin and/or hair.

Annals of Geriatric Medicine and Research 2024;28(2):192-200
Background:
This study aimed to determine whether changes in phase angle during rehabilitation are associated with clinical outcomes such as activities of daily living (ADL), skeletal muscle mass index (SMI), and strength in patients with osteoporotic fractures.
Methods:
This retrospective observational study included patients with osteoporotic fractures admitted to convalescent rehabilitation wards. Changes in phase angle were defined as the difference between the phase angle values at discharge and on admission. The primary outcome was the Functional Independence Measure motor (FIM-motor) score at discharge. The secondary outcomes were SMI and handgrip strength at discharge. We used multivariate analysis to adjust for confounding factors and examine the association between changes in the phase angle and outcomes.
Results:
We analyzed a total of 115 patients (97 women, mean age of 81.0±10.0 years), with a median change in phase angle of 0° during hospitalization. We observed increased phase angles in 49 patients (43%), with a median increase of 0.2°. Multiple regression analysis showed that changes in phase angle were independently associated with FIM-motor score at discharge (β=0.238, p=0.027). Changes in phase angle were not significantly associated with SMI (β=0.059, p=0.599) or handgrip strength (β=-0.032, p=0.773) at discharge.
Conclusion
An increased phase angle during rehabilitation was positively associated with ADL improvement in patients with osteoporotic fractures. These findings may help clinicians make informed decisions regarding patient care and treatment strategies for better outcomes.

Canine mammary gland tumors (CMGTs), which are the most common neoplasms in sexually intact female dogs, have been suggested as a model for studying human breast cancer because of several similarities, including relative age of onset, risk factors, incidence, histological and molecular features, biological behavior, metastatic pattern, and responses to therapy. In the present study, we established a new cell line, the SNP cell line, from a CMGT. A tumor formed in each NOD.CB17-Prkdc (scid)/J mouse at the site of subcutaneous SNP cell injection. SNP cells are characterized by proliferation in a tubulopapillary pattern and are vimentin positive. Moreover, we examined miRNA expression in the cultured cells and found that the expression values of miRNA-143 and miRNA-138a showed the greatest increase and decrease, respectively, of all miRNAs observed, indicating that these miRNAs might play a significant role in the malignancy of SNP cells. Overall, the results of this study indicate that SNP cells might serve as a model for future genetic analysis and clinical treatments of human breast tumors.
