Aging and cell expansion enhance microRNA diversity in small extracellular vesicles produced from human adipose-derived stem cells.

Unlabelled: Adipose-derived stem cells (ASCs) and their small extracellular vesicles (sEVs) hold significant potential for regenerative medicine due to their tissue repair capabilities. The microRNA (miRNA) content in sEVs varies depending on ASC status; however, the effects of aging and cell passage on miRNA profiles remain unclear. In this study, we examined the effects of donor age and cell expansion on ASC characteristics and transcriptome using ASCs obtained from three young and three old donors.

Bilateral renal subcapsular hematoma caused by polyarteritis nodosa: a case report.

Polyarteritis nodosa, which is a systemic vasculitis of small- and medium-sized arteries, can cause arterial aneurysms in various organs, sometimes resulting in aneurysm rupture and hemorrhage. A kidney is one of the major targets of polyarteritis nodosa. Here, we report a 73-year-old woman who presented with sudden-onset high fever, diarrhea, and renal injury with bilateral renal subcapsular hematoma shown on contrast-enhanced computed tomography scan.

[Exploratory Study of the Risk Factors for Acute Kidney Injury in the Cisplatin Combination Chemotherapy for Solid Cancer].

In the present study, we investigated the rate of cisplatin(CDDP)-induced acute kidney injury(CIA)and examined its association with various clinical factors in the combination therapy with CDDP for solid cancers. A total of 726 cases of solid cancer that had been indicated for the CDDP combination regimen from December 2012 to December 2013 were enrolled. CIA occurred in 48 cases(6.

Crescentic IgA nephropathy after administration of human monoclonal interleukin-12/23p40 antibody in a patient with Crohn's disease: a case report.

Ustekinumab (UST), an interleukin (IL)-12/IL-23-blocking monoclonal antibody, is a novel therapeutic option for Crohn's disease (CD). We describe a 24-year-old man with CD who showed an abrupt decline in renal function after administration of UST. Twenty-nine months previously, the patient was diagnosed with CD, and abnormal urinalysis findings in health checkup were coincidentally found at that time.

Long-term maintenance of functional primary human hepatocytes using small molecules.

The immediate deterioration of primary human hepatocytes (PHHs) during culture limits their utility in drug discovery studies. Here, we report that a cocktail of four small molecule signaling inhibitors, termed YPAC, is useful for maintaining various hepatic functions of PHHs, including albumin and urea productivity, glycogen storage, and cytochrome P450 (CYP) expression. Most importantly, we found that YPAC allows PHHs to retain enzymatic activities of CYP1A2, CYP2B6, and CYP3A4 even after 40 days of culture, and that inducibility of CYP3A4 activity in response to the prototypical inducers rifampicin and phenobarbital is also maintained.

[Associations between Clinical Factors and Acute Renal Failure Due to Cisplatin Combination Chemotherapy for Lung Cancer].

In this study, we investigated the clinical factors associated with acute kidney injury (AKI) due to combination therapy with cisplatin (CDDP) for treating lung cancer. We classified cases according to the presence or absence of adequate hydration and magnesium(Mg)administered above the regulations of the registered regimen to evaluate the effect due to differences in hydration on AKI. We also investigated clinical factors before and after administration of CDDP in each case group, and examined their association with AKI.

Multiple lesions of intracoronal resorption of permanent teeth in the developing dentition: a case report.

The purpose of this case report is to describe an unusual presentation of multiple lesions of intracoronal resorption in the permanent teeth in a healthy boy. Longitudinal radiographs demonstrated that all 3 lesions were acquired after the crowns were completely formed. Unlike previous reports in which intracoronal radiolucencies have been found in unerupted teeth or in newly erupting teeth, one lesion in this case developed in a fully erupted tooth, which was differentiated from internal resorption and invasive cervical resorption of the root.
