Physiotherapists' Experiences with the Hip Disability and Knee Injury Osteoarthritis Outcome Score Following Total Hip and Knee Arthroplasty: A Qualitative Interview Study.

Clinical guidelines for physiotherapy following total hip and knee arthroplasty (THA/TKA) recommend using Patient-Reported Outcome Measures (PROMs) like the Hip disability and Knee injury Osteoarthritis Outcome Score (HOOS/KOOS). However, it remains unclear how physiotherapists use these PROMs in daily clinical practice. To explore primary care physiotherapists' experiences with the HOOS/KOOS in daily clinical practice following THA and TKA.

Utilisation of the Hip Disability and Knee Injury Osteoarthritis Outcome Score in physiotherapy following total hip and knee arthroplasty: a cross-sectional survey.

Objective: To explore the frequency of administration and the usage of the Hip Disability and Knee injury Osteoarthritis Outcome Scores (HOOS/KOOS) and their Physical function Short forms (HOOS-PS/KOOS-PS) by physiotherapists after total hip and knee arthroplasties (THA/TKA).

Design: A cross-sectional study using an open online survey.

Setting: Primary care physiotherapy practices affiliated with the Dutch Association for Quality in Physiotherapy.

Modulating CRISPR-Cas Genome Editing Using Guide-Complementary DNA Oligonucleotides.

Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) has revolutionized genome editing and has great potential for many applications, such as correcting human genetic disorders. To increase the safety of genome editing applications, CRISPR-Cas may benefit from strict control over Cas enzyme activity. Previously, anti-CRISPR proteins and designed oligonucleotides have been proposed to modulate CRISPR-Cas activity.

Forecasting transitions in the state of food security with machine learning using transferable features.

Food insecurity is a growing concern due to man-made conflicts, climate change, and economic downturns. Forecasting the state of food insecurity is essential to be able to trigger early actions, for example, by humanitarian actors. To measure the actual state of food insecurity, expert and consensus-based approaches and surveys are currently used.

NDFIP allows NEDD4/NEDD4L-induced AQP2 ubiquitination and degradation.

Regulation of our water homeostasis is fine-tuned by dynamic translocation of Aquaporin-2 (AQP2)-bearing vesicles to and from the plasma membrane of renal principal cells. Whereas binding of vasopressin to its type-2 receptor initiates a cAMP-protein kinase A cascade and AQP2 translocation to the apical membrane, this is counteracted by protein kinase C-activating hormones, resulting in ubiquitination-dependent internalization of AQP2. The proteins targeting AQP2 for ubiquitin-mediated degradation are unknown.

Vasopressin increases S261 phosphorylation in AQP2-P262L, a mutant in recessive nephrogenic diabetes insipidus.

Background: Mutations in the aquaporin-2 (AQP2) gene cause nephrogenic diabetes insipidus (NDI), a renal disorder characterized by polyuria due to a lacking antidiuretic response to vasopressin. While most AQP2 mutants in recessive NDI are misfolded and retained in the endoplasmic reticulum, AQP2-P262L in NDI was impaired in its vasopressin-dependent translocation from vesicles to the plasma membrane.

Methods: Vasopressin-induced translocation of AQP2 coincides with AQP2 phosphorylation at S256, S264 and T269 and dephosphorylation at S261.

Impaired basolateral sorting of pro-EGF causes isolated recessive renal hypomagnesemia.

Primary hypomagnesemia constitutes a rare heterogeneous group of disorders characterized by renal or intestinal magnesium (Mg(2+)) wasting resulting in generally shared symptoms of Mg(2+) depletion, such as tetany and generalized convulsions, and often including associated disturbances in calcium excretion. However, most of the genes involved in the physiology of Mg(2+) handling are unknown. Through the discovery of a mutation in the EGF gene in isolated autosomal recessive renal hypomagnesemia, we have, for what we believe is the first time, identified a magnesiotropic hormone crucial for total body Mg(2+) balance.

Molecular determinants of permeation through the cation channel TRPM6.

TRPM6 and its closest relative TRPM7 are members of the Transient Receptor Potential Melastatin (TRPM) subfamily of cation channels and are known to be Mg2+ permeable. By aligning the sequence of the putative TRPM6 pore with the pore sequences of the other subfamily members, we located in the loop between the fifth and the sixth transmembrane domain, a stretch of amino acids residues, 1028GEIDVC1033, as the potential selectivity filter. Two negatively charged residues, E1024 (conserved in TRPM6, TRPM7, TRPM1 and TRPM3) and D1031 (conserved along the entire TRPM subfamily), were identified as important determinants of cation permeation through TRPM6, because neutralization of both residues into an alanine resulted in non-functional channels.

Identification of BSPRY as a novel auxiliary protein inhibiting TRPV5 activity.

Transient receptor potential vallinoid 5 (TRPV5) and TRPV6 are the most Ca2+-selective members of the TRP superfamily and are essential for active Ca2+ (re)absorption in epithelia. However, little is known about intracellular proteins that regulate the activity of these channels. This study identified BSPRY (B-box and SPRY-domain containing protein) as a novel factor involved in the control of TRPV5.
