Keratin 15 promotes a progenitor cell state in basal keratinocytes of skin epidermis.

The type I intermediate filament proteins keratin 14 (K14) and keratin 15 (K15) are common to all complex epithelia. K14 is highly expressed by progenitor keratinocytes, in which it provides essential mechanical integrity and gates keratinocyte entry into differentiation by sequestering YAP1, a transcriptional effector of Hippo signaling, to the cytoplasm. K15 has long been used as a marker of hair bulge stem cells though its specific role in skin epithelia is unknown.

A coding single nucleotide polymorphism in the interleukin-6 receptor enhances IL-6 signalling in CD4 T cells and predicts treatment response to tocilizumab in giant cell arteritis.

Objectives: The study objective was to determine if a common single nucleotide polymorphism in the interleukin 6 (IL-6) receptor (rs2228145, p.Asp358Ala) predicted treatment response to tocilizumab in giant cell arteritis (GCA).

Methods: Genetic sequencing of the rs2228145 locus was performed in 2 independent cohorts of patients with GCA.

Varied Growth Media Necessitate Different Light Regimes for Indoor Duckweed Cultivation.

Controlled indoor cultivation of duckweed plants can support remediation of wastewaters through generation of plant biomass. Despite numerous advantages, indoor cultivation of duckweeds on agri-food wastewaters remains underexplored. Lighting regimes need to be optimised for duckweed growth and affordability of energy consumption, as it has been shown that the composition of wastewater growth medium can alter light utilisation.

Longitudinal qualitative assessment of meaningful symptoms and relevance of WATCH-PD digital measures for people with early Parkinson's.

Background: Longitudinal qualitative data on what matters to people with Parkinson's disease are lacking and needed to guide patient-centered clinical care and development of outcome measures.

Objective: To evaluate change over time in symptoms, impacts, and relevance of digital measures to monitor disease progression in early Parkinson's.

Methods: In-depth, online symptom mapping interviews were conducted with 33 people with early Parkinson's at baseline and 1 year later to evaluate (A) symptoms, (B) impacts, and (C) relevance of digital measures to monitor personally relevant symptoms.

Optimisation of Dairy Soiled Water as a Novel Duckweed Growth Medium.

As a result of intensive agriculture, large quantities of liquid wastewaters are produced. Dairy soiled water (DSW) is produced in large volumes during the milking process of cattle. It comprises essential plant nutrients such as nitrogen, phosphorus, and potassium.
