The effect of experimentally increasing the postpartum protein supply on plasma protein synthesis, rumen tissue proliferation, and immune homeostasis was studied using 8 periparturient Holstein cows in a complete randomized design. At calving, cows were assigned to abomasal infusion of water (CTRL) or casein (CAS) in addition to a lactation diet. Casein infusion was gradually decreased from 696 ± 1 g/d at +2 d relative to calving (DRTC) to 212 ± 10 g/d at +29 DRTC to avoid excessive supply. Synthesis rate of plasma proteins was measured at -14, +4, +15, and +29 DRTC by measuring [C]Phe isotopic enrichment in arterial plasma free Phe, total plasma proteins, and albumin after 3, 5, and 7 h of jugular ring[C]Phe infusion...

Immunosensors are used to detect the presence of certain bio-reagents mostly targeted at the diagnosis of a condition or a disease. Here, a general purpose electrical immunosensor has been fabricated for the quantitative detection of multiple bio-reagents through the formation of an antibody-antigen pair. The sensors were fabricated using all printing approaches. 2D transition metal dichalcogenide (TMDC) MoS2 thin film was deposited using Electrohydrodynamic atomization (EHDA) on top of an interdigitated transducer (IDT) electrode fabricated by reverse offset printing...

dTMP-GH is a chimeric protein containing a tandem dimer of thrombopoietin mimetic peptide (dTMP) fused to human growth hormone (hGH) prepared previously by our team. It shows significant bioactivity in promoting thrombocytopoiesis, but detection of intact dTMP-GH in plasma is still a challenge due to the presence of endogenous hGH. In this study, a rabbit polyclonal antibody with high affinity to dTMP was obtained with a BSA-conjugated immunogen composed of 20 amino acids sequence spanning two TMP and the linker...

Objective: The idea that different sports and physical training type results in different cardiac adaptations has been widely accepted. However, this remodelling process among different sport modalities is still not fully understood. Thus, the current study aims to investigate the heart morphology variation associated with a set of different modalities characterized by distinct models of preparation and different methods and demands of training and completion. Method: The sample comprises 42 basketball players, 73 roller hockey players, 28 judo athletes and 21 swimmers...

BACKGROUND: Dalazatide is a specific inhibitor of the Kv1.3 potassium channel. The expression and function of Kv1.3 channels are required for the function of chronically activated memory T cells, which have been shown to be key mediators of autoimmune diseases, including psoriasis. OBJECTIVE: The primary objective was to evaluate the safety of repeat doses of dalazatide in adult patients with mild-to-moderate plaque psoriasis. Secondary objectives were to evaluate clinical proof of concept and the effects of dalazatide on mediators of inflammation in the blood and on chronically activated memory T cell populations...

One of the key necessary steps to prevent human neurological disorders is the efficient disruption of protein aggregation or amyloid fibril. In this article, we have explored the effect of three amphiphilic surface active ionic liquids (SAILs) namely 1-methyl-3-octylimidazolium chloride ([C8mim]Cl), 1-dodecyl-3-methyllimidazolium chloride ([C12mim]Cl) and 1-hexadecyl-3-methyllimidazolium chloride ([C16mim]Cl) having concentration of 5.8 mM, 0.29 mM and 0.08 mM respectively on bovine serum albumin (BSA) and human serum albumin (HSA) fibril...

A label-free electrochemical impedance spectroscopy (EIS) aptasensor for rapid detection (<35 min) of interferon-gamma (IFN-γ) was fabricated by immobilizing a RNA aptamer capture probe (ACP), selective to IFN-γ, on a gold interdigitated electrode array (Au IDE). The ACP was modified with a thiol group at the 5' terminal end and subsequently co-immobilized with 1,6-hexanedithiol (HDT) and 6-mercapto-1-hexanolphosphate (MCH) to the gold surface through thiol-gold interactions. This ACP/HDT-MCH ternary surface monolayer facilitates efficient hybridization with IFN-γ and displays high resistance to nonspecific adsorption of nontarget proteins [i...

Surface blocking is a well-known process for reducing unwanted nonspecific adsorption in sensor fabrication, especially important in the emerging field where DNA/RNA applied. Bovine serum albumin (BSA) is one of the most popular blocking agents with an isoelectric point at pH 4.6. Although it is widely recognized that the adsorption of a blocking agent is strongly affected by its net charge and the maximum adsorption is often observed under its isoelectric form, BSA has long been perfunctorily used for blocking merely in neutral solution, showing poor blocking performances in the optical-fiber evanescent wave (OFEW) based sensing toward DNA target...

Selective and efficient preconcentration is indispensable for low concentration of phosphopeptides in phosphorylated protein-related samples prior to MS-based analysis. Herein, an on-chip system coupled magnetic SPE with MALDI-TOF MS was designed. A metal oxide affinity chromatography (MOAC) material, indium oxide, was coated on the surface of Fe3 O4 magnetic nanoparticles (MNPs) to prepare the adsorbent, spatially confined with an applied magnetic field. The adsorbent exhibited high selectivity for phosphopeptides in tryptic digests of the mixture of β-casein and BSA (1:1000) and the mixture of β-casein, BSA, and ovalbumin (1:100:100)...

Controlled immobilization of sugar probes is of key importance for the development of glycan biosensors. To this end, a series of BSA-sugar conjugates with different numbers of mannose units are prepared via the squaric acid-mediated coupling reaction. The conjugates can absorb directly on gold substrate without any derivation reactions, thus providing a simple and effective method for the construction of SPR-based glycan biosensors. SPR measurements show that the BSA-mannose conjugate with 11 mannoses exhibit the highest affinity to the lectin concanavalin A with a limit of detection of ca...

We studied seasonal and annual changes in visual body condition scores (BCSs), and assessed how these scores were related to levels of faecal glucocorticoid metabolites (fGCMs) in free-ranging Asian elephants (Elephas maximus) in the seasonally dry tropical forests of the Mysore and Nilgiri Elephant Reserves in southern India. We assessed the animals' BCS visually on a scale of 1 to 5; where 1 represents a very thin and 5 represents a very fat elephant. To understand the influence of seasonality on BCS, we sampled the population during dry (n = 398) and wet seasons (n = 255) of 2013 and 2015 while, for annual changes in BCS, we sampled nine free-ranging adult females from different family groups that had been repeatedly sighted over seven years...

In this study, novel peripherally tetra 3-morpholinophenol substituted zinc(II) phthalocyanine (4) and its water soluble form quaternized zinc(II) phthalocyanine (ZnQ) were synthesized for the first time. These novel compounds were characterized by a combination of different spectroscopic techniques such as FT-IR, (1)H NMR, (13)C NMR, UV-Vis and mass. The DNA binding of ZnQ was investigated using UV-vis absorption titration, competitive ethidium bromide, thermal denaturation and viscosity experiments that the ZnQ bound to CT-DNA via intercalation mode...

Asparaginase is commonly de-emphasized/omitted in adult acute lymphoblastic leukemia regimens due to poor tolerability, including hepatotoxicity (HTX). Adult patients (n = 100) given induction therapy containing pegylated asparaginase (PEG) from January 2008 to February 2016 were evaluated for HTX. Sixteen patients met criteria for HTX (direct bilirubin >3 g/dL). A multivariable model identified body surface area >2m(2) (OR 7.40; 95% CI: 1.73-31.61, p = .007), albumin <3 mg/dL (OR 4.62; 95% CI: 1...

A 50+ SPF sunscreen decreased significantly cutaneous vitamin D production following a single narrow-band (nb)UVB exposure, independently from the body surface area exposed. In contrast, the circulating 25(OH)D3 levels were only minimally affected. It is probable that another endogenous source of precursors is selected when skin-originated precursors are lacking. PURPOSE: Sunscreen use, highly advocated for preventing cutaneous carcinogenesis, is potentially leading to an aggravation of vitamin D deficiency with its consequences on bone health...

Acute akinesia (AA) is an unusual motor complication in Parkinson's disease (PD). Reported risk factors for AA include infection, trauma, surgical intervention, and the withdrawal of antiparkinsonian medication. Recently, patients with genetic PD were reported to have a three-fold risk of AA than patients with non-genetic PD. We describe a patient with PD associated with a Parkin mutation in whom serious akinesia developed. A 42-year-old man with exon 2 heterozygous deletion and exon 4 heterozygous deletion in the PARK2 gene showed five unexpected AA for several 12h...
