BACKGROUND Contact dermatitis resulting from the use of shin pads is usually caused by rubber components, dyes, benzoyl peroxide, or formaldehyde resins. OBJECTIVES To investigate and identify a new allergen in shin pads that was responsible for severe contact dermatitis in a young football player. METHODS High-performance liquid chromatography (HPLC) of samples of shin pads was performed. ...

The aim of this study was to assess whether slanted gel pads can be used to optimize beam-flow angles and flow velocity measurements for Doppler ultrasound. The right carotid artery of a single healthy female volunteer was measured alternatively five times without and with an 18° angled slanted gel pad between the ultrasound transducer and skin by 13 radiologists. Beam-flow angles and peak syst...

OBJECTIVE The introduction of shoulder pads has coincided with a rise in shoulder impact injuries in the game of rugby. In this study, the effect of shoulder pads on impact force attenuation was quantified. DESIGN Four different commercially available shoulder pads were tested for material properties. Hard and soft objects were dropped from predetermined heights onto a force plate imparting p...

Tree frogs use adhesive toe pads for climbing on a variety of surfaces. They rely on wet adhesion, which is aided by the secretion of mucus. In nature, the pads will undoubtedly get contaminated regularly through usage, but appear to maintain their stickiness over time. Here, we show in two experiments that the toe pads of White's tree frogs (Litoria caerulea) quickly recover from contamination...

This paper presents PADS, a policy architecture for building distributed storage systems. A policy architecture has two aspects. First, a common set of mechanisms that allow new systems to be implemented simply by defining new policies. Second, a structure for how policies, themselves, should be specified. In the case of distributed storage systems, PADS defines a data plane that provides a fix...

It is well-established that the sympathetic nervous system (SNS) regulates adipocyte metabolism and recently it has been reported that sensory afferents from white fat overlap anatomically with sympathetic efferents to white fat. The studies described here characterize the response of intact fat pads to selective sympathectomy (local 6-hydroxydopamine (6OHDA) injections) of inguinal (ING) or ep...

Psychiatric advance directives (PADs) statutes presume competence to complete these documents, but the range and dimensions of decisional competence among people who actually complete PADs is unknown. This study examines clinical and neuropsychological correlates of performance on a measure to assess competence to complete PADs and investigates the effects of a facilitated PAD intervention on d...

Peptidylarginine deiminases (PADs) convert arginine within a peptide (peptidylarginine) into peptidylcitrulline. Citrullination by human PADs is important in normal physiology and inflammation. Porphyromonas gingivalis, a major pathogen in periodontitis, is the only prokaryote described to possess PAD. P. gingivalis infection may generate citrullinated peptides, which trigger anti-citrullinated...

Factors that may be significant in rationalizing physician overrides of psychiatric advance directives (PADs) are not only features of individual clinical scenarios, but also are artifacts of the faltering mental health system being navigated by both provider and patient. This system, frequently viewed as hostile to consumer choice and increasingly focused on reacting to recurrent crises, is no...
