The relationship between the supination resistance test, lower limb biomechanics and the effects of foot orthoses on foot and ankle biomechanics in individuals with posterior tibialis tendon dysfunction during gait.

Background: Posterior tibialis tendon dysfunction (PTTD) is a debilitating condition that leads to biomechanical changes, for which foot orthoses are often prescribed to attenuate. There is a need to improve the ability to predict these biomechanical alterations, determine the biomechanical effectiveness of foot orthoses, and anticipate their effects on individuals with PTTD during gait.

Research Question: Is the supination resistance test (SRT) reliable, and capable of predicting foot and ankle biomechanics, as well as the biomechanical effects of foot orthoses in individuals with PTTD during gait?

Methods: Twenty-one individuals with PTTD participated with supination resistance measured over two sessions.

Pustular psoriasis of pregnancy: A rare cause of placental insufficiency.

Generalised pustular psoriasis of pregnancy (GPPP) is a rare dermatosis that presents in the third trimester. It merits careful clinical assessment given the difficulty in diagnosis, impact on maternal health and association with placental insufficiency. We present a case of generalised pustulosis in a pregnant woman at 30 weeks' gestation and describe the clinico-pathological challenges in obtaining a diagnosis of GPPP.

SABRE-SHEATH Hyperpolarization of [1,5-C]Z-OMPD for Noninvasive pH Sensing.

Hyperpolarized (HP) C-labeled probes are emerging as promising agents to noninvasively image pH in vivo. HP [1,5-C]Z-OMPD (Z-4-methyl-2-oxopent-3-enedioic acid) in particular has recently been used to simultaneously report on kidney perfusion, filtration, and pH homeostasis, in addition to the ability to detect local tumor acidification. In previous studies, dissolution dynamic nuclear polarization was used to hyperpolarize Z-OMPD.

Nasopharynx Cancer in the United States: Racial and Ethnic Disparities in Stage at Presentation.

Introduction: Although nasopharynx cancer (NPC) is rare in the United States, global epidemiology varies greatly. Therefore, understanding NPC disparities in the diverse US setting is critical.

Methods And Materials: Data from the National Cancer Database (NCDB, 2004-2021) identified patients with NPC; NCDB allows disaggregation by Asian American (AA) subgroups.

Computationally Driven Discovery of T Center-like Quantum Defects in Silicon.

Quantum technologies would benefit from the development of high-performance quantum defects acting as single-photon emitters or spin-photon interfaces. Finding such a quantum defect in silicon is especially appealing in view of its favorable spin bath and high processability. While some color centers in silicon have been emerging in quantum applications, there remains a need to search for and develop new high-performance quantum emitters.
