Yiheng Luo, Wenchao Dou, Guangying Zhao
In this article, a facile and sensitive electrochemical method for quantification of Salmonella Pullorum and Salmonella Gallinarum (S. Pullorum and S. Gallinarum) was established by monitoring glucose consumption with a personal glucose meter (PGM). Antibody-functionalized magnetic nanoparticles (IgG-MNPs) were used to capture and enrich S. Pullorum and S. Gallinarum, and IgG-MNPs-S. Pullorum and IgG-MNPs-S. Gallinarum complexes were magnetically separated from a sample using a permanent magnet. The trace tag was prepared by loading polyclonal antibodies and high-content glucose oxidase on amino-functionalized silica nanoparticles (IgG-SiNPs-GOx)...

Tissue damage is regarded as an unwanted medical condition to be avoided. However, introducing tolerable tissue damages has been used as a therapeutic intervention in traditional and complementary medicine to cure discomfort and illness. Eccentric exercise is known to cause significant necrosis and insulin resistance of skeletal muscle. The purpose of this study was to determine the magnitude of muscle damage and blood glucose responses during an oral glucose tolerance test (OGTT) after eccentric training in 21 young participants...

BACKGROUND: The aim of this study was to assess the hemodynamic parameters analyzed in bioimpedance cardiography during maximal exercise in patients with type 1 diabetes differing in insulin resistance. METHODS: The study group consisted of 40 men with type 1 diabetes. Tissue sensitivity to insulin was assessed on the basis of the glucose disposal rate (GDR) analyzed during hyperinsulinemic-euglycemic clamp. Patients were divided into groups with GDR <4.5 mg/kg/min (G1 group-lower insulin sensitivity) and GDR ≥4...

The Diabetes Technology Society surveillance protocol provides a seal of approval for a glucose meter if a sufficient number of a candidate glucose meter's results meet ISO 15197:2013 limits. The protocol provides clear details about how to conduct this study and analyze the data but has two flaws. There is no specification about the size of glucose meter errors that are outside of ISO limits. A meter that has a result in the E zone of a glucose meter error grid could receive the DTS seal of approval. In addition, the protocol uses the ISO standard, which could be considered a "state of the art" standard instead of an error grid, which is a clinical standard...

A new technology to quantify phospho-p53(15) by converting its content to the amount of glucose which is detectable by a glucometer was developed. An immunochromatographic test strip (ITS) was used as a disposable platform, where primary antibody (Ab1)-modified Fe3O4 magnetic nanoparticles (Fe3O4-Ab1) were settled on the test zone to capture both the target phospho-p53(15) and the detection antibody (Ab2)-glucose encapsulating liposome (GEL) conjugate. The measurement was based on the release and subsequent detection of glucose from Ab2-GEL using a glucose meter (GM)...

OBJECTIVES: To evaluate and validate a hand-held electrochemical meter (Precision Xtra®) as a screening test for subclinical ketosis and hypoglycaemia in lactating dairy cattle. DESIGN: Method comparison study using a convenience sample. PROCEDURE: Blood samples were collected into plain tubes from the coccygeal vessels of 181 Holstein cows at 2-4 weeks of lactation during summer in Iran. Blood β-hydroxybutyrate concentration (BHB) and glucose concentration were immediately measured by the electrochemical meter after applying 20 μL of blood to the reagent strip...

STUDY QUESTION: Do naturally occurring, hyperandrogenic (≥1 SD of population mean testosterone, T) female rhesus monkeys exhibit traits typical of women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: Hyperandrogenic female monkeys exhibited significantly increased serum levels of androstenedione (A4), 17-hydroxyprogesterone (17-OHP), estradiol (E2), LH, antimullerian hormone (AMH), cortisol, 11-deoxycortisol and corticosterone, as well as increased uterine endometrial thickness and evidence of reduced fertility, all traits associated with PCOS...

BACKGROUND: Reliability of continuous glucose monitors (CGM) is a prerequisite for therapeutic dosing of insulin without the need for confirmatory blood glucose meter measurements. Interference of CGMs with commonly prescribed substances has not been extensively evaluated. METHODS: We sought to undertake a novel pilot study to determine the susceptibility of FDA-approved CGM systems (Medtronic Guardian Sof-Sensor, Dexcom G4 Platinum) to erroneous readings in the presence of common medications...

INTRODUCTION: We have previously demonstrated that tight glycemic control (80-120 mg/dl) improves outcome in critically injured patients. However, many centers have gotten away from aggressive glucose control due to the workload and risk of hypoglycemia. The objective of this pivotal trial is to evaluate the first in human continuous inline glucose monitor (OptiScanner) in critically ill patients. METHODS: A multicenter pivotal trial was conducted over a 1 year period (2014-2015) at 4 major academic centers in 200 critically ill patients...

BACKGROUND: Diabetes health care relies on the HbA1c (A1c) assay and associated average glucose (AG) to evaluate and control chronic glycemia. However, the A1c assay is plagued with significant noise, lag time, and specificity issues. Current studies support the significant health care advantage of clinical action based on real-time blood glucose (BG) metrics. We seek to improve diabetes management by directly relating such metrics to AG levels as mediated by recently discovered recurrent endocrine cycles...

PURPOSE: To assess the inhibitory effects of nitrite on plaque acidogenicity and its relationship with caries experience. MATERIALS AND METHODS: Plaque (2 μl) was collected from 76 children (age 5.8 = 2.6 years, dmft = 2.9 = 3.5, DMTF = 0.6 = 1.4) and mixed with nitrite solution (final concentration = 0.63 mM) or distilled water (control). The initial pH (pH-0) of each sample was measured using a portable pH meter. The samples were incubated for 10 min, then their pH (pH-1) was measured again...

BACKGROUND: Despite significant advances in type 1 diabetes (T1D) management, achieving targeted glycemic control in pediatric patients remains a struggle. Continuous glucose monitoring (CGM) with remote access holds the promise to address this challenge by allowing caregivers to monitor glucose, even when the child is not directly under their supervision. OBJECTIVE: To explore real-time and remote CGM practices in homes and schools, including caregiver expectations regarding this technology...

Diabetic ketoacidosis is an infrequent but life-threatening acute complication of diabetes, affecting predominantly patients with type 1 diabetes, children, and pregnant women, where ketosis is usually associated with marked hyperglycemia. Recently, an increasing number of cases have been reported of euglycemic diabetic ketoacidosis in patients with type 2 diabetes receiving sodium-glucose cotransporter 2 inhibitor treatment in routine practice. There is a minor, but not negligible diabetic ketoacidosis risk associated with this drug class, which was not seen in randomized clinical trials...

Electrochemical detection methods have been popular in the medical diagnostics field. Several well-known devices such as the self-monitoring blood glucose meter have relied on electrochemical techniques for their sensitivity, and ability to make direct measurements without optical labels. Currently, no point-of-care or handheld diagnostic tool exists to quantify the severity of a traumatic brain injury (TBI). We have shown that enzymatic detection of norepinephrine (NE), a biomarker which can indicate TBI severity, using impedance-based electrochemical techniques can achieve the required sensitivity, ∼100 pg/mL...

Obesity is a disorder of body weight regulatory systems characterized by an accumulation of excess body fat. World Heath Organization recommended that 66% of deaths now occur in developing countries and recognizes obesity as a leading risk factor. Obesity is associated with chronic, low grade, systemic inflammation. The inflammatory state plays a causal role in the development of insulin resistance, type 2 diabetes and the metabolic syndrome. This study will design to evaluate the relation between obesity with fasting blood sugar (FBS)...

This study examined the relationship between self-monitoring of blood glucose (SMBG) and glycaemic control among patients from Cameroon. A minority of patients with diabetes owned a blood glucose meter; of these patients, most performed SMBG inconsistently. The lack of SMBG may be a contributing factor to the poor glycaemic control in the country.
