Stability, preservation and storage of As(III), DMA, MMA and As(V) in water samples.

Anal Methods 2021 Jun 24. Epub 2021 Jun 24.

P S Analytical Ltd, Arthur House, Crayfields Industrial Park, Main Road, Orpington, BR5 3HP, UK.

Correct handling and preservation of water samples is crucial to ensure their integrity for arsenic speciation measurements. ISO TS 19620:2018 is a method for the determination of arsenic(iii) and arsenic(v) species in waters by liquid chromatography (LC) coupled to inductively coupled plasma mass spectrometry (ICP-MS) or hydride generation atomic fluorescence spectrometry (HG-AFS). During the development of this method, a study was performed to establish the best practices for storage and preservation of samples to maintain the integrity of the arsenic speciation and stability.

Relationship Between Plantar Callosity and Foot Deformity in Hallux Valgus Using Weightbearing Computed Tomography.

J Foot Ankle Surg 2021 May 26. Epub 2021 May 26.

Department of Orthopaedic Surgery, Sapporo Medical University School of Medicine, Sapporo, Japan.

Plantar callosities under lesser metatarsals are often accompanied by the hallux valgus, and the cause of callosity is thought to be associated with the foot deformity, such as the metatarsal length discrepancy, the abnormal metatarsal head height, cavus, flat foot, and rheumatoid conditions. However, it is unclear which variable is most involved in the cause of callosity in hallux valgus deformity. To clarify the factors associated with the callosity with hallux valgus deformity, we conducted multiple image assessments based on weightbearing radiography and computed tomography. Read More

Periwound skin care considerations for older adults.

Br J Community Nurs 2021 Jun;26(Sup6):S26-S33

Senior Tissue Viability Nurse and Clinical Operational programme improvement Lead, Welsh Wound Innovation Centre.

This article discusses the effects of ageing on the skin, particularly the main structural and functional changes that occur in the epidermis and dermis that make the skin more vulnerable to damage. Specific alterations that occur with ageing include slower epidermal turnover, flattening of the epidermal-dermal junction, loss of moisture and hydration as well as reduced immunity placing the skin at increased risk of damage. The discussion will also examine common periwound complications associated with ageing including; maceration, excoriation, dry skin, hyperkeratosis, callus, contact dermatitis and eczema. Read More

Department of Physical Activity Sciences and Podiatric Medicine, Université du Québec à Trois-Rivières, 3351, boul. des Forges, C.P. 500, Trois-Rivières, G9A 5H7, Canada.

Background: An intractable plantar keratoma (IPK) is a conical thickening of the epidermis' stratum corneum and a common cause of foot pain which can have a significant, detrimental impact on the mobility, quality of life and independence of individuals. Conservative treatments are currently offered to patients with IPK, but they are unsatisfactory since they do not offer a sufficient or permanent reduction of symptoms. The purpose of this study was the evaluation of the feasibility, safety and effectiveness of innovative treatments for intractable plantar keratoma (IPK). Read More

MET currents and otoacoustic emissions from mice with a detached tectorial membrane indicate the extracellular matrix regulates Ca near stereocilia.

J Physiol 2021 04 9;599(7):2015-2036. Epub 2021 Mar 9.

Department of Biomedical Science, University of Sheffield, Sheffield, UK.

Key Points: The aim was to determine whether detachment of the tectorial membrane (TM) from the organ of Corti in Tecta/Tectb mice affects the biophysical properties of cochlear outer hair cells (OHCs). Tecta/Tectb mice have highly elevated hearing thresholds, but OHCs mature normally. Mechanoelectrical transducer (MET) channel resting open probability (P ) in mature OHC is ∼50% in endolymphatic [Ca ], resulting in a large standing depolarizing MET current that would allow OHCs to act optimally as electromotile cochlear amplifiers.
