BACKGROUND: Closely related pathologic disorders sometimes manifest with the same symptoms, making for a complex differential diagnosis. This is the situation in plantar fasciitis (PF) and myofascial pain syndrome (MPS) with myofascial trigger points (MTPs) in the sole of the foot. This research assessed the analgesic effect on plantar pain of combination therapy with interferential current stimulation therapy (ICST), treating MTPs in the great toe adductor muscle and the short flexor muscles of the toes in patients whose diagnosis was compatible with PF or MPS...

The prolactin-inducible protein (PIP) is considered a valuable biomarker that is associated with both benign and malignant pathological conditions of the mammary gland. The function of PIP in breast tumorigenesis remains unknown; however, evidence from our laboratory and others suggest that it regulates host immunity. Studies with PIP-deficient (PIP-/- ) mice demonstrated significantly lower numbers of CD4+ T cells in their secondary lymphoid organs, impaired Th1 response, and impaired nitric oxide (NO) production...

STUDY QUESTION: Is ceramide-1-phosphate (C1P) an ovarian protective agent during alkylating chemotherapy? SUMMARY ANSWER: Local administration of C1P drastically reduces ovarian damage induced by cyclophosphamide (Cy) via protection of follicular reserve, restoration of hormone levels, inhibition of apoptosis and improvement of stromal vasculature, while protecting fertility, oocyte quality and uterine morphology. WHAT IS KNOWN ALREADY: Cancer-directed therapies cause accelerated loss of ovarian reserve and lead to premature ovarian failure (POF)...

Piezo2 ion channels are critical determinants of the sense of light touch in vertebrates. Yet, their regulation is only incompletely understood. We recently identified myotubularin related protein-2 (Mtmr2), a phosphoinositide (PI) phosphatase, in the native Piezo2 interactome of murine dorsal root ganglia (DRG). Here, we demonstrate that Mtmr2 attenuates Piezo2-mediated rapidly adapting mechanically activated (RA-MA) currents. Interestingly, heterologous Piezo1 and other known MA current subtypes in DRG appeared largely unaffected by Mtmr2...

Sorting nexins anchor trafficking machines to membranes by binding phospholipids. The paradigm of the superfamily is sorting nexin 3 (SNX3), which localizes to early endosomes by recognizing phosphatidylinositol 3-phosphate (PI3P) to initiate retromer-mediated segregation of cargoes to the trans-Golgi network (TGN). Here we report the solution structure of full length human SNX3, and show that PI3P recognition is accompanied by bilayer insertion of a proximal loop in its extended Phox homology (PX) domain. Phosphoinositide (PIP) binding is completely blocked by cancer-linked phosphorylation of a conserved serine beside the stereospecific PI3P pocket...

During plant-pathogen interactions, pathogenic bacteria have evolved multiple strategies to cope with the sophisticated defense systems of host plants. Proline iminopeptidase (PIP) is essential to Xanthomonas campestris pv. campestris (Xcc) virulence, and conserved in many plant-associated bacteria, but its pathogenic mechanism remains unclear. In this study, we found that disrupting pip in Xcc enhanced its flagella-mediated bacterial motility by decreasing intracellular c-di-GMP levels, and overexpression of pip restricted bacterial motility by elevating c-di-GMP levels...

Whether the antimutagenic DNA repair protein MGMT works solo in human cells and if it has other cellular functions is not known. Here, we show that human MGMT associates with PCNA and in turn, with the cell cycle inhibitor, p21cip1 in glioblastoma and other cancer cell lines. MGMT protein was shown to harbor a nearly perfect PCNA-Interacting Protein (PIP box) motif. Isogenic p53-null H1299 cells were engineered to express the p21 protein by two different procedures. Reciprocal immunoprecipitation/western blotting, Far-western blotting, and confocal microscopy confirmed the specific association of MGMT with PCNA and the ability of p21 to strongly disrupt the MGMT-PCNA complexes in tumor cells...

BACKGROUND: Renal function progressively worsens with age. Potentially inappropriate prescribing (PIP) of renally excreted active drugs (READs) is common in older adults, leading to an increased rate of iatrogenic illness. The Ghent Older People's Prescription community Pharmacy Screening (GheOP3 S-) tool is an effective, explicit instrument that was developed for community pharmacists (CPs) to detect PIP. So far, this tool does not assess PIP of the frequently used READs in older patients with renal impairment...

Chromium-based metal-organic framework (MOF) Cr-MIL-100/101 activated by activator and aluminum trialkyl compound serve as unique, highly efficient heterogeneous single-site catalysts for the controlled polymerization of isoprene, which not only exhibit quasi-living nature in isoprene polymerization but also unprecedentedly switch from cyclic to cis-1,4-selectivity depending on the activator used to yield low molecular weight cyclic PIPs or extremely high molecular weight cis-1,4-PIPs. Such heterogeneous Cr-MOF catalysts can be recycled approximately five times...

In the present study, the effects of nine compounds on the luminol-O2 chemiluminescence (CL) reaction catalyzed by gold nanoparticles (Au NPs) were investigated. p-Iodophenol (PIP), known as a traditional enhancer in horseradish peroxidase (HRP)-catalyzed luminol-H2 O2 CL reaction, exhibited the highest enhancement effect on the luminol-O2 -Au NPs CL reaction. The addition of PIP at a final concentration of 1.25 mM to luminol-O2 -Au NPs CL system enhanced the CL signal almost 30-fold. Interestingly, the enhanced CL reaction exhibited a slow and intense CL signal which is different from the CL profile of luminol-H2 O2 -Au NPs CL system reported in previously...

For the majority of Belgian hospitals, a pharmacist-led full medication review process is not standard care and, therefore, challenging to introduce. With this study, we aimed to evaluate the successes and barriers of the implementation of a pharmacist-led full medication review process in the geriatric ward at a local Belgian hospital. To this end, we carried out an interventional study, performing a full medication review on older patients (≥70 years) with polypharmacy (≥5 drugs) who had an unplanned admission to the geriatric ward...
