Diabetic nephropathy (DN) is one of the most significant long‑term complications in terms of morbidity and mortality for diabetic patients; however, the exact cause remains unknown. To address this, the DN model was established, and oxidative stress indexes, including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH‑Px), and inflammatory cytokines, includinginterleukin‑6 (IL‑6), tumor necrosis factor‑alpha (TNF‑α) and transforming growth factor‑beta (TGF‑β), were examined by ELISA...

Recently, PARIS (ZNF746) is introduced as authentic substrate of parkin and transcriptionally represses PGC-1α by binding to insulin responsive sequences (IRSs) in the promoter of PGC-1α. The overexpression of PARIS selectively leads to the loss of dopaminergic neurons (DN) and mitochondrial abnormalities in the substantia nigra (SN) of Parkinson's disease (PD) models. To identify PARIS target molecules altered in SN region-specific manner, LC-MS/MS-based quantitative proteomic analysis is employed to investigate proteomic alteration in the cortex, striatum, and SN of AAV-PARIS injected mice...

Approximately one-third of diabetic patients develop evidence of nephropathy. Pathogenesis of diabetic nephropathy (DN) remains unclear; however, some genetic and metabolic risk factors have been determined for the development and progression of DN. In the recent genetic studies, polymorphism of apolipoprotein E (ApoE) gene has been reported as a risk factor for the development of DN; however, the results are inconsistent. The aim of the present study was to evaluate the association between ApoE polymorphism and nephropathy in Iranian patient with type 2 diabetes...

Diabetic nephropathy (DN) is the leading cause of kidney disease; however, there are no early biomarkers and no cure. Thus, there is a large unmet need to predict which individuals will develop nephropathy and to understand the molecular mechanisms that govern this susceptibility. We compared the glomerular transcriptome from mice with distinct susceptibilities to DN at four weeks after induction of diabetes, but before histologic injury, and identified differential regulation of genes that modulate inflammation...

OBJECTIVES: Human papillomavirus (HPV) deoxyribonucleic acid (DNA)-based testing is increasingly used for cervical cancer screening in developed countries, but the best approach to utilizing it in low- and middle-income countries (LMIC) is unclear. Incorporation of HPV DNA-based testing into routine antenatal care (ANC) is a potential yet poorly explored strategy for cervical cancer screening in LMIC. We explored the attitude of health care workers and pregnant women to the incorporation of HPV DNA-based tests into routine ANC in Nigeria...

Advanced glycation end products (AGEs) play a role in pathogenesis of diabetic nephropathy (DN). Myo-inositol Oxygenase (MIOX) has been implicated in tubulo-interstitial injury in the context of DN. We investigated the effect of AGEs on MIOX expression and delineated mechanisms that lead to tubulo-interstitial injury. Status of MIOX, RAGE and relevant cellular signaling pathways activated following AGE:RAGE interaction were examined in tubular cells and kidneys of AGE-BSA treated mice. Solid phase assay revealed an enhanced binding of RAGE with AGE-BSA, -laminin and -collagen IV...

BACKGROUND: The coexistence of depression with mild cognitive impairment (MCI) seems to increase the risk of dementia. However, the explanations of that relationship have been inconsistent. We investigated cognitive profiles in patients with MCI with and without depression and whether changes in depression symptoms affect cognition longitudinally. METHODS: For the study, 161 patients with MCI were divided into a depressed group (D+) and a nondepressed group (D-)...

BACKGROUND: Shoulder pain of musculoskeletal origin is the main cause of upper limb pain of non-traumatic origin. Despite being one of the most common reasons for consultation, there is no established protocol for treatment due to the complexity of its etiology. However, it has been shown that the presence of myofascial trigger points on the shoulder muscles is a common condition associated with patients suffering from shoulder pain. This protocol has been created which describes the design of a randomized controlled trial to evaluate the effectiveness of the inclusion of dry needling (DN) within a protocol of manual physiotherapy and therapeutic exercise in the treatment of chronic shoulder pain of unspecific origin...

This case report describes a 40-year-old male who presented with posterior thigh pain managed unsuccessfully with massage therapy, chiropractic adjustments, and physical therapy. The diagnosis of myofascial pain syndrome (MPS) involving the quadratus femoris (QF) was purely clinical, based on palpatory findings and ruling out other conditions through deductive reasoning. This is potentially a first time report, describing the successful management of MPS of the QF with dry needling (DN) using a recently published DN grading system...

A new approach for the calibration of SEC-light scattering (SEC-LS) setups is proposed, which requires solely the molar mass of a reference polymer. Neither the specific refractive index increment of the calibrant nor of the analyte is required. Comparison of the molar masses derived in different solvents for a large number of chemically different polymers shows that the new approach yields the same molar masses as if molar masses were derived using dn/dc to calibrate the light scattering setup. The approach therefore allows easier determination of molar masses by SEC-LS...

The CLAVATA3/ESR-RELATED (CLE) peptide signals are required for cell-cell communication in several plant growth and developmental processes. However, little is known regarding possible functions of the CLEs in the anther. Here, we show that a T-DNA insertional mutant, and dominant-negative (DN) and overexpression (OX) transgenic plants of the CLE19 gene exhibited significantly reduced anther size and pollen grain number, and abnormal pollen wall formation. Interestingly, the DN-CLE19 pollen grains showed a more extensively covered surface but CLE19-OX pollen exine exhibited clearly missing connections in the network and lacked separation between areas that normally form the lacunae...

INTRODUCTION AND AIMS: Osteolytic bone metastases are observed in advanced cases of breast cancer. In vitro data suggest that the activity of the calcium-sensing receptor (CaSR) expressed by metastatic cells could potentiate their osteolytic potential. This study aimed to demonstrate in vivo the involvement of the CaSR in breast cancer cells osteolytic potential and to identify potential targets linked to CaSR activity. METHODS AND RESULTS: MDA-MB-231 stably transfected with plasmids containing either a full-length wild-type CaSR (CaSR-WT), or a functionally inactive dominant negative mutant (CaSR-DN) or an empty vector (EV) were intratibially injected into Balb/c-Nude mice...

Human mucosal-associated invariant T (MAIT) cells are an important T cell subset that are enriched in tissues and possess potent effector functions. Typically such cells are marked by their expression of Vα7.2-Jα33/Jα20/Jα12 T cell receptors, and functionally they are major histocompatibility complex class I-related protein 1 (MR1)-restricted, responding to bacterially derived riboflavin synthesis intermediates. MAIT cells are contained within the CD161++ Vα7.2+ T cell population, the majority of which express the CD8 receptor (CD8+), while a smaller fraction expresses neither CD8 or CD4 coreceptor (double negative; DN) and a further minority are CD4+...

Myrciaria cauliflora is a functional food rich in anthocyanins, possessing antioxidative and anti-inflammatory properties. Our previous results demonstrated M. cauliflora extract (MCE) had beneficial effects in diabetic nephropathy (DN) and via the inhibition of Ras/PI3K/Akt and kidney fibrosis-related proteins. The purpose of this study was to assess the benefit of MCE in diabetes associated with kidney inflammation and glycemic regulation in streptozotocin-nicotinamide (STZ/NA)-induced diabetic mice. Compared with the untreated diabetic group, MCE significantly improved blood glucose and serum biochemical characteristic levels...

Podocytes serve a critical role in the development of many glomerular diseases, including diabetic nephropathy (DN). Epigallocatechin‑3‑gallate (EGCG), a predominant polyphenolic component of green tea, has indicated its therapeutic effects in diabetes. In the present study, mouse podocyte cells were cultured in vitro, cell injury was induced by high glucose, and the protective effect of EGCG on cell proliferation and apoptosis and the underlying mechanisms were investigated. The results demonstrated that high glucose significantly inhibited cell proliferation after 48 and 72 h compared with normal glucose and mannitol treatment...

The utility of thermoresponsive hydrogels, such as those based on poly(N-isopropylacrylamide) (PNIPAAm), is severely limited by their deficient mechanical properties. In particular, the simultaneous achievement of high strength and stiffness remains unreported. In this work, a thermoresponsive hydrogel is prepared having the unique combination of ultrahigh compressive strength (≈23 MPa) and excellent compressive modulus (≈1.5 MPa). This is accomplished by employing a double network (DN) design comprised of a tightly crosslinked, highly negatively charged 1st network based on poly(2-acrylamido-2-methylpropane sulfonic acid (PAMPS) and a loosely crosslinked, zwitterionic 2nd network based on a copolymer of thermoresponsive NIPAAm and zwitterionic 2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (MEDSAH)...

To determine the spatiotemporal relationships among intrinsic networks of the human brain, we recruited seven neurosurgical patients (4 males; 3 females) who were implanted with intracranial depth electrodes. We first identified canonical resting state networks at the individual subject level using an iterative matching procedure on each subject's resting state fMRI data. We then introduced single electrical pulses to fMRI pre-identified nodes of the default (DN), frontoparietal (FPN) and salience networks (SN) while recording evoked responses in other recording sites within the same networks...
