DNA methylation and whole-genome transcription analysis in CD4 T cells from systemic lupus erythematosus patients with or without renal damage.

Background: Lupus nephritis (LN) is the most common cause of kidney injury in systemic lupus erythematosus (SLE) patients and is associated with increased mortality. DNA methylation, one of the most important epigenetic modifications, has been reported as a key player in the pathogenesis of SLE. Hence, our article aimed to explore DNA methylation in CD4 T cells from LNs to identify additional potential biomarkers and pathogenic genes involved in the progression of LN.

Nanosecond pulsed electric field ablates rabbit VX2 liver tumors in a non-thermal manner.

Background: Liver tumor remains an important cause of cancer-related death. Nanosecond pulsed electric fields (nsPEFs) are advantageous in the treatment of melanoma and pancreatic cancer, but their therapeutic application on liver tumors need to be further studied.

Methods: Hep3B cells were treated with nsPEFs.

Transient upregulation of EGR1 signaling enhances kidney repair by activating SOX9 renal tubular cells.

Acute kidney injury (AKI) is associated with damage to the nephrons and tubular epithelial cells (TECs), which can lead to chronic kidney disease and end-stage renal disease. Identifying new biomarkers before kidney dysfunction will offer crucial insight into preventive and therapeutic options for the treatment of AKI. Early growth response 1 (EGR1) has been found to be a pioneer transcription factor that can sequentially turn on/off key downstream genes to regulate whole-body regeneration processes in the leopard worm.

14-3-3ζ inhibits maladaptive repair in renal tubules by regulating YAP and reduces renal interstitial fibrosis.

Acute kidney injury (AKI) refers to a group of common clinical syndromes characterized by acute renal dysfunction, which may lead to chronic kidney disease (CKD), and this process is called the AKI-CKD transition. The transcriptional coactivator YAP can promote the AKI-CKD transition by regulating the expression of profibrotic factors, and 14-3-3 protein zeta (14-3-3ζ), an important regulatory protein of YAP, may prevent the AKI-CKD transition. We established an AKI-CKD model in mice by unilateral renal ischemia-reperfusion injury and overexpressed 14-3-3ζ in mice using a fluid dynamics-based gene transfection technique.

Luminescence of TbAlO phosphors co-doped with Ce/Gd for white light-emitting diodes.

Tb CeGdAlO phosphors were synthesized through solid-state reactions. The influence of Gd on the luminescence was investigated. Under the excitation at 460 nm, TbCeAlO shows the characteristic emission band of Ce with a peak wavelength at about 554 nm.

Modulation of Macrophage Polarization by Human Glomerular Mesangial Cells in Response to the Stimuli in Renal Microenvironment.

Mesangial cell (MC) activation and macrophage infiltration are 2 major events closely related with each other in mesangial proliferative glomerulonephritis. In the anti-Thy 1 nephritis model, macrophages mediate the damage and also the expansion of mesangium through secreting various inflammatory factors; however, in glomerular microenvironment how MCs affect macrophage activity in the presence of various stimuli have not yet been understood. In the present study, we found that resting human MCs (HMCs) constitutively expressed chemokine [C-C motif] ligand 2 (CCL-2) and interleukin (IL)-6 and induced M2 polarization of macrophages in the coculture system.

Retrospective analysis of tacrolimus combined with Tripterygium wilfordii polyglycoside for treating idiopathic membranous nephropathy.

Background: Idiopathic membranous nephropathy (IMN) is one of the most common adult nephrotic syndromes. Some patients with this disorder require immunosuppressive therapy. This retrospective case series was performed to assess the effects of tacrolimus (TAC) combined with Tripterygium wilfordii polyglycoside (TWG) in treating IMN.

Risk Factors and Adverse Pregnancy Outcomes of Succenturiate Placenta: A Case-Control Study.

Objective: To identify risk factors associated with succenturiate placenta and to evaluate the association between adverse pregnancy outcomes and succenturiate placenta in singleton pregnancies.

Study Design: The total population of women (n = 28,256) with singleton pregnancies who delivered in Zhangqiu City Hospital during the study period between 2002 and 2012 was reviewed. Risk factors.

Modulation of cyclins and p53 in mesangial cell proliferation and apoptosis during Habu nephritis.

Background: Mesangial cell (MC) proliferation and apoptosis are the main pathological changes observed in mesangial proliferative nephritis. In this study, we explored the role of cyclins and p53 in modulating MC proliferation and apoptosis in a mouse model of Habu nephritis.

Methods: The Habu nephritis group was prepared by injection of Habu toxin.

Comparison of two fluid solutions for resuscitation in a rabbit model of crush syndrome.

Background: Crush syndrome is a common injury, the main characteristics of which include acute kidney injury. However, there is still lack of reliable animal model of crush syndrome, and it also remains controversial as to which type of fluid should be chosen as a more appropriate treatment option for prevention and treatment of acute kidney injury.

Methods: The rabbits were crushed at the lower limbs for 6 h with 36 times the body weight, which means the pressure of each leg was also 36 times the body weight.

Mesenchymal stem cells ameliorate sepsis-associated acute kidney injury in mice.

Objective: Significant progress has been made in critical care medicine during the past several decades. However, the mortality rate is still high in patients with sepsis, especially with acute kidney injury (AKI). Mesenchymal stem cells (MSCs) possess an ability to ameliorate renal injury from ischemia-reperfusion, but it is still unknown whether they have the ability to reduce sepsis-associated AKI.

Comparison of Hantaan and Seoul viral infections among patients with hemorrhagic fever with renal syndrome (HFRS) in Heilongjiang, China.

Background: Hemorrhagic fever with renal syndrome (HFRS) is a serious public health problem in China, and is primarily caused by either the Hantaan virus (HTNV) or Seoul virus (SEOV) strains. However, the causative hantavirus has only been definitively identified in a few HFRS cases, and detailed comparisons of patient data for the 2 strains are limited.

Methods: We conducted a 1-y prospective study in Heilongjiang Province, China.

NFIA haploinsufficiency is associated with a CNS malformation syndrome and urinary tract defects.

Complex central nervous system (CNS) malformations frequently coexist with other developmental abnormalities, but whether the associated defects share a common genetic basis is often unclear. We describe five individuals who share phenotypically related CNS malformations and in some cases urinary tract defects, and also haploinsufficiency for the NFIA transcription factor gene due to chromosomal translocation or deletion. Two individuals have balanced translocations that disrupt NFIA.

Disruption of ROBO2 is associated with urinary tract anomalies and confers risk of vesicoureteral reflux.

Congenital anomalies of the kidney and urinary tract (CAKUT) include vesicoureteral reflux (VUR). VUR is a complex, genetically heterogeneous developmental disorder characterized by the retrograde flow of urine from the bladder into the ureter and is associated with reflux nephropathy, the cause of 15% of end-stage renal disease in children and young adults. We investigated a man with a de novo translocation, 46,X,t(Y;3)(p11;p12)dn, who exhibits multiple congenital abnormalities, including severe bilateral VUR with ureterovesical junction defects.
