Dual Immunoglobulin Domain-Containing Cell Adhesion Molecule Increases Early in Renal Tubular Cell Injury and Plays Anti-Inflammatory Role.

Dual immunoglobulin domain-containing cell adhesion molecule (DICAM) is a type I transmembrane protein that presents in various cells including renal tubular cells. This study evaluated the expression and protective role of DICAM in renal tubular cell injury. HK-2 cells were incubated and treated with lipopolysaccharide (LPS, 30 μg/mL) or hydrogen peroxide (HO, 100 μM) for 24 h.

Impact of Ring Finger Protein 20 and Its Downstream Regulation on Renal Tubular Injury in a Unilateral Nephrectomy Mouse Model Fed a High-Fat Diet.

Abnormal lipid metabolism increases the relative risk of kidney disease in patients with a single kidney. Using transcriptome analysis, we investigated whether a high-fat diet leads to abnormalities in lipid metabolism and induces kidney cell-specific damage in unilateral nephrectomy mice. Mice with unilateral nephrectomy fed a high-fat diet for 12 weeks exhibited progressive renal dysfunction in proximal tubules, including lipid accumulation, vacuolization, and cell damage.

In vivo imaging of renal microvasculature in a murine ischemia-reperfusion injury model using optical coherence tomography angiography.

Optical coherence tomography angiography (OCTA) provides three-dimensional structural and semiquantitative imaging of microvasculature in vivo. We developed an OCTA imaging protocol for a murine kidney ischemia-reperfusion injury (IRI) model to investigate the correlation between renal microvascular changes and ischemic damage. Mice were divided into mild and moderate IRI groups according to the duration of ischemia (10 and 35 mins, respectively).

The TAC with AAT group was cotreated with daily subcutaneous injections of TAC and intraperitoneal injections of AAT (80 mg/kg) for four weeks.

The Crucial Role of Xanthine Oxidase in CKD Progression Associated with Hypercholesterolemia.

In the present study, we investigated the effects of xanthine oxidase (XO) inhibition on cholesterol-induced renal dysfunction in chronic kidney disease (CKD) mice, and in low-density lipoprotein (LDL)-treated human kidney proximal tubule epithelial (HK-2) cells. ApoE knockout (KO) mice underwent uninephrectomy to induce CKD, and were fed a normal diet or high-cholesterol (HC) diet along with the XO inhibitor topiroxostat (1 mg/kg/day). HK-2 cells were treated with LDL (200 µg/mL) and topiroxostat (5 µM) or small interfering RNA against xanthine dehydrogenase (siXDH; 20 nM).

NOX1 Inhibition Attenuates Kidney Ischemia-Reperfusion Injury via Inhibition of ROS-Mediated ERK Signaling.

The protective effects of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) 1 inhibition against kidney ischemia-reperfusion injury (IRI) remain uncertain. The bilateral kidney pedicles of C57BL/6 mice were clamped for 30 min to induce IRI. Madin-Darby Canine Kidney (MDCK) cells were incubated with HO (1.

Comparison of the short-term effects of hyperbaric oxygen therapy and complex decongestive therapy on breast cancer-related lymphedema: A pilot study.

Although there have been some reports that hyperbaric oxygen therapy (HBOT) is effective in treating breast cancer-related lymphedema (BCRL), controversy regarding its therapeutic effects remains.We sought to evaluate the efficacy of HBOT in addition to conventional complex decongestive therapy (CDT) for BCRL.A prospective observational study was conducted on 10 patients with BCRL.

Alpha-1 antitrypsin inhibits formaldehyde-induced apoptosis of human peritoneal mesothelial cells.

Background: The alpha-1 antitrypsin (AAT) protein has an important role in the anti-inflammatory and apoptotic response. AAT inhibits not only serine proteases but also cysteine and aspartic proteases. Apoptosis results from the sequential activation of cysteine proteases of the caspase family.

Effects of Different Bandaging Methods for Treating Patients With Breast Cancer-Related Lymphedema.

Objective: To compare the treatment effects, satisfaction with the treatment, and performance improvement following bandage treatment using the spiral method and spica method for breast cancer-related lymphedema (BCRL).

Methods: A prospective study with 46 patients with BCRL was conducted. All patients were divided into either the spiral or spica group for non-elastic bandage therapy and received the same treatment for 2 weeks, apart from the group-specific bandaging method used.

Successful treatment of decompression sickness complicated with acute hepatic infarction and acute kidney injury: a case report.

Decompression sickness is a disease caused by abrupt pressure change and presents various symptoms. To date, acute kidney injury associated with decompression sickness has been reported frequently, but there is no report of hepatic infarction associated with decompression sickness. We report a case of acute kidney injury and acute hepatic infarction treated with hyperbaric oxygen (HBO2) therapy and dialysis in a patient with severe decompression sickness after work diving.

The emerging role of xanthine oxidase inhibition for suppression of breast cancer cell migration and metastasis associated with hypercholesterolemia.

Hypercholesterolemia is reported to increase reactive oxygen species (ROS) and to promote breast cancer progression. ROS play an important role in tumor biology, and xanthine oxidase (XO) is an enzyme that generates ROS. The effects of febuxostat (FBX), an XO inhibitor, on breast cancer cell migration under LDL stimulation and metastasis of breast cancer associated with hypercholesterolemia were studied.

Hypoxanthine induces cholesterol accumulation and incites atherosclerosis in apolipoprotein E-deficient mice and cells.

Reactive oxygen species (ROS) generation during purine metabolism is associated with xanthine oxidase and uric acid. However, the direct effect of hypoxanthine on ROS generation and atherosclerosis has not been evaluated. Smoking and heavy drinking are associated with elevated levels of hypoxanthine.

Central cord syndrome in a 7-year-old boy secondary to standing high jump.

Acute traumatic central cord syndrome is commonly associated with major trauma such as falling and motor vehicle crash, but minor or nontraumatic causes are very rare in children. As a consequence, most physicians frequently overlook children presenting with complaints of arm weakness when history of any definite major trauma does not exist, especially in the emergency department. We present the case of a 7-year-old boy who was experiencing weakness in both arms after a standing high jump with tilting his head back in school.
