PURPOSE To present a revised interpretation of the work-up data that enabled diagnosis of preperimetric glaucoma (PPG) at the first examination. METHODS a) Literature analysis on PPG; b) 6-year follow-up of a glaucoma-suspect patient. RESULTS TWO NEW CONCEPTS MAY BE ADAPTED: (a) the objective finding of retinal nerve fiber layer (RNFL) thinning below the normal border in the opposing typica...

This paper presents an active noise cancellation technique for recovering wearable biosensor signals corrupted by bodily motion. A finger mounted photoplethysmograph (PPG) ring sensor with a collocated MEMS accelerometer is considered. The system by which finger acceleration disturbs PPG output is identified and a means of modeling this relationship is prescribed using either FIR or Laguerre mo...

The purpose of this study was to establish heart rate variability normative data on obese children and to comparing the accuracy of two medical technologies photoplethesmography (PPG) with electrocardiography (ECG) while measuring heart rate variability (HRV). PPG is a relatively new technique that holds promise for health care practitioners as an evaluative tool and biofeedback instrument due ...

The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of 131 alkyl polyethylene glycol (PEG)/polypropylene glycol ethers as used in cosmetics, concluding that these ingredients are safe in the present practices of use and concentration described in this safety assessment when formulated to be nonirritating. Most of the alkyl PEG/PPG ethers included in this review are reported to...

In their recent article, Cukierman-Yaffe et al. (1) performed a cross-sectional study comparing the relationship of A1C and fasting plasma glucose (FPG) levels with performance on four cognitive tests of subjects from the Memory in Diabetes (MIND) substudy of the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial. These authors showed that a chronic marker of hyperglycemia, A1C, w...

OBJECTIVES Powered paragliding (PPG) and paragliding are two totally different sports, mainly because of the use of an engine in powered paragliding. As a consequence, the pattern of injuries caused by each of these two sports may be different. SETTING To test this hypothesis, we analysed 384 incident reports gathered by the US Powered Paragliding Association from 1995 to 2012. The majority o...

In cerebral-cortical membranes, hydrolysis-resistant guanine nucleotides exert a dual regulatory effect on phospholipase C activity. Nanomolar concentrations of guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG) or guanosine 5'-[gamma-thio]triphosphate (GTP[S]) inhibited basal phospholipase C activity, with a maximum inhibition of 30% at 10 nM. Increasing the concentration of p[NH]ppG or GT...

1 Continuous monitoring of arterial blood pressure (ABP) can provide vital information on the 2 cardiovascular system in clinical practice and research. To achieve this, methods have been 3 developed to determine ABP continuously and non-invasively, including the wrist volume 4 clamp method, which uses reflection-mode photoplethysmography (PPG) to indicate the 5 volume change of the radial arte...

The aim of this study was to assess the efficacy of a combination therapy of vildagliptin plus an α-glucosidase inhibitor for patients with type II diabetes mellitus. Type II diabetic patients exhibiting poor glycemic control following α-glucosidase inhibitor treatment for at least two months were selected and randomly distributed into vildagliptin and placebo groups. The body weight, fasting b...

In the presence of 1 microM atrial natriuretic factor (ANF) and low (0.1 mM) Mg2+ concentrations, the initial rate of binding of [3H]guanosine 5'-[beta, gamma-imido)triphosphate [( 3H]p[NH]ppG) to rat lung plasma membranes was increased twofold to threefold. ANF-dependent stimulation of the initial rate of [3H]p[NH]ppG binding was reduced at high (5 mM) Mg2+ concentrations. Preincubation of mem...
