Combinatorial lipidomics and proteomics underscore erythrocyte lipid membrane aberrations in the development of adverse cardio-cerebrovascular complications in maintenance hemodialysis patients.

Patients on maintenance hemodialysis exhibit a notably higher risk of cardio-cerebrovascular complications that constitute the major cause of death. Preceding studies have reported conflicting associations between traditional lipid measures and clinical outcome in dialysis patients. In this prospective longitudinal study, we utilized quantitative lipidomics to elucidate, at molecular resolution, changes in lipidome profiles of erythrocyte and plasma samples collected from maintenance hemodialysis patients followed up for 86 months (≈7 years).

Photoinduced decarboxylative germylation of α-fluoroacrylic acids: access to germylated monofluoroalkenes.

Herein, a novel strategy is presented for the photoinduced decarboxylative and dehydrogenative cross-coupling of a wide range of α-fluoroacrylic acids with hydrogermanes. This methodology provides an efficient and robust approach for producing various germylated monofluoroalkenes with excellent stereoselectivity within a brief photoirradiation period. The feasibility of this reaction has been demonstrated through gram-scale reaction, conversion of germylated monofluoroalkenes, and modification of complex organic molecules.

Effect of ultrafiltration on cerebral small-vessel disease and related outcomes in hemodialysis.

Background: Increasing evidence suggests a high prevalence of cerebral small-vessel disease (CSVD) in hemodialysis patients. Variable ultrafiltration during hemodialysis may contribute to brain lesions by inducing hemodynamic instability. We aimed to investigate the effect of ultrafiltration on CSVD and relative outcome in this population.

Increased Premature Cerebral Small Vessel Diseases in Dialysis Patients: A Retrospective Cross-Sectional Study.

Background: Growing data indicate a higher prevalence of cerebrovascular diseases in patients with ESRD. Cerebral small-vessel disease (CSVD) is an important risk factor of stroke and dementia. A comprehensive assessment of CSVD in a dialysis population is needed.

Carotid intima-media thickness relative to cognitive impairment in dialysis patients, and their relationship with brain volume and cerebral small vessel disease.

Background: Carotid intima-media thickness (cIMT) is considered a risk factor for and predictor of cerebrovascular disease. In this study, we explored the contribution of cIMT to cognitive impairment (CI) in dialysis patients and the role of cerebral small vascular disease (CSVD) and brain atrophy in this process.

Methods: Cognitive function was assessed using a comprehensive cognitive test battery.

Cerebral microbleeds and their influence on cognitive impairment in Dialysis patients.

Cerebral microbleeds (CMBs) in dialysis patients have recently attracted much attention, and the different locations of CMBs indicate different pathological processes. Previous studies on the relationship between CMBs and cognitive impairment (CI) in the general population and in dialysis patients have reported controversial results. A total of 180 chronic dialysis patients were enrolled in our study.

Membranous nephropathy occurring with type 2 diabetes mellitus .

Background: The incidence of type 2 diabetes mellitus (T2DM) is increasing, and membranous nephropathy (MN) occurs frequently with T2DM. We investigated the clinicopathological features and outcomes of patients with T2DM and MN.

Methods: A total of 137 patients with biopsy-proven MN and T2DM were enrolled in this retrospective study.

Product wastage from modern human growth hormone administration devices: a laboratory and computer simulation analysis.

Background: Treatment of growth hormone disorders typically involves daily injections of human growth hormone (GH) over many years, incurring substantial costs. We assessed the extent of undesired GH loss due to leakage in the course of pen preparation prior to injection, and differences between the prescribed dose, based on patient weight, and the actual delivered dose based on pen dosing increments in five GH administration devices.

Methods: Norditropin® prefilled FlexPro®, NordiFlex®, NordiLet®, and durable NordiPen®/SimpleXx® 5 mg pens (Novo Nordisk A/S, Bagsværd, Denmark) and durable Omnitrope® Pen-5 devices (Sandoz, Holzkirchen, Germany) were tested (n = 40 for each device type).

Effect of LY294002 on adriamycin-induced epithelial-mesenchymal transition in human breast carcinoma cells.

Objective: To study the effect of LY294002 on the adriamycin- induced epithelial-mesenchymal transition in human breast carcinoma cells.

Methods: Human breast carcinoma cells MCF-7 was cultured in vitro and then exposed to adriamycin with or without LY294002. The protein expression levels of Akt, phosphorylated-Akt (p-Akt), Snail, and E-cadherin was detected by Western blot analysis.
