Objectives. Despite increased awareness of the high prevalence and significance of foot and ankle problems in rheumatoid arthritis (RA), feet remain neglected. Reasons may include the perception that feet are difficult to assess, they are not included in the DAS28, and lack of freely available foot screening tools specific for RA. Methods. The Swindon Foot and Ankle Questionnaire (SFAQ) is a si...

A radioaerosol technique has been used to investigate whether the size distribution of aerosols released from a jet nebuliser affects the amount of aerosol delivered to the lungs. Six subjects with mild asthma (FEV1 81% of predicted) were studied on three occasions. On each visit they received one of three aerosols tagged with technetium-99m in 0.9% saline. The aerosols were generated by either...

Glycerol 1:2-cyclic phosphate is released simultaneously with glycerophosphate when kidney glycerophosphinicocholine diesterase (EC 3.1.4.2) acts on glycerylphosphorylcholine and glycerylphosphorylethanolamine. The percentage of cyclic phosphate ester formed is increased at pH values below the optimum and is decreased when Mg2+ or Ca2+ is added to stimulate the reaction.

The structural integrity of unilamellar vesicles has been studied in vitro and in vivo by use of gamma-ray perturbed angular correlation techniques. These studies utilize 111In3+ weakly bound to the chelator nitrilotriacetic acid as a probe to monitor the percentage of intact vesicles. When complexes of 111In3+ and nitrilotriacetic acid is encapsulated in vesicles, 111In3+ exhibits a fast tumbl...

Attachment of Amblyomma hebraeum females, either around feeding males or in areas in which extracts of fed males had previously been placed, was studied. The percentage attachment of female ticks around feeding males was significantly higher than that inside extract-treated areas. It was also found that the percentage attachment around the males increases with time, but there is little or no in...

Sustainable agriculture aims to eliminate the excessive usage of chemical fertilizers and can be crucial for soil fertility. A factorial pot experiment in a randomized complete block design was carried out King Khaled International Airport Nursery, Riyadh, Saudi Arabia, during 2019/2020, evaluate role biofertilizer (i.e., Bio-Fert, nitrogen-fixing microorganisms; Biot-Phos, phosphorus-released ...

Percentage error (relative to the observed value) is often felt to be more meaningful than the absolute error in isolation. The mean absolute percentage error (MAPE) is widely used in forecasting as a basis of comparison, and regression models can be fitted which minimize this criterion. Unfortunately, no formula exists for the coefficients, and models for a given data set may not be unique. We...
