High detail resolution cellulose structures through electroprinting.

Electrospinning is a technique used to fabricate polymer fibers in micro- and nanoscales. Due to the large distance between the nozzle and collector, there is a limited positioning accuracy of electrospun fibers. To enhance the possibility of fabricating structures with micrometer placement, an electroprinting technique has been developed.

From balance to imbalance: disruption of plasma glutathione concentration in micropapillary thyroid carcinoma.

Background: Despite the presence of evidence that establishes a strong correlation between oxidative stress and thyroid cancer, there exists a scarcity of research that investigates the specific role of glutathione as an important antioxidant in this particular context. The objective of this study was to assess the altered balance of oxidative stress in cases of thyroid cancer, which includes both papillary thyroid carcinoma (PTC) and micro PTC (mPTC), by examining and comparing the total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), reduced glutathione (GSH), oxidized glutathione (GSSG), and GSSG/GSH ratio with those of individuals diagnosed with multinodular goiter (MNG) as well as Healthy subjects.

Materials And Methods: Plasma samples were collected from 92 patients (23 mPTC, 23 PTC, 23 MNG, 23 Healthy).

Direct ink writing of high-resolution cellulose structures.

3D printing is envisioned to play an important role in the production of membranes for e.g., water purification and bio-separation applications due to the prospect of creating new and cleverly designed structures.

Morphological Changes in Astrocytes by Self-Oxidation of Dopamine to Polydopamine and Quantification of Dopamine through Multivariate Regression Analysis of Polydopamine Images.

Astrocytes, also known as astroglia, are important cells for the structural support of neurons as well as for biochemical balance in the central nervous system (CNS). In this study, the polymerization of dopamine (DA) to polydopamine (PDA) and its effect on astrocytes was investigated. The polymerization of DA, being directly proportional to the DA concentration, raises the prospect of detecting DA concentration from PDA optically using image-processing techniques.

Directed Connectivity Analysis of the Neuro-Cardio- and Respiratory Systems Reveals Novel Biomarkers of Susceptibility to SUDEP.

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of epilepsy-related mortality and its pathophysiological mechanisms remain unknown. We set to record and analyze for the first time concurrent electroencephalographic (EEG), electrocardiographic (ECG), and unrestrained whole-body plethysmographic (Pleth) signals from control (WT - wild type) and SUDEP-prone mice (KO- knockout Kcna1 animal model). Employing multivariate autoregressive models (MVAR) we measured all tri-organ effective directional interactions by the generalized partial directed coherence (GPDC) in the frequency domain over time (hours).

Colloidal HSA - Graphene oxide nanosheets for sustained release of oxaliplatin: Preparation, release mechanism, cytotoxicity and electrochemical approaches.

A novel sustained release carrier of graphene oxide nanosheets functionalized by human serum albumin nanoparticles (FGO-NSs) was synthesized and characterized by field emission scanning electron microscopy (FESEM), zeta sizer analysis, absorption spectroscopy (UV-vis) and Fourier transform infrared spectroscopy (FTIR) studies. The cell viability of GO-NSs, HSA-NPs and FGO-NSs has been tested against human foreskin fibroblast normal cell line, HFFF2 by MTT assay technique. Loading efficiency and release properties of oxaliplatin (OX), as an effective chemotherapeutic agent in the treatment of cancers, from HSA-NPs and FGO-NSs were studied.
