We intend to describe a case of McCune-Albright Syndrome (MAS), a rare disease characterized by fibrous dysplasia (FD), cutaneous hyperpigmentation and hyperfunctioning endocrinopathies (HFE).

We report the case of a 13-year-old male child who presented with a

macule in the lumbosacral region and disabling polyostotic FD, requiring several surgical interventions and bisphosphonates from the age of 3years (Y)+9months (M)due to persistent and severe pain. Hyperthyroidism (HT) became apparent at 5Y+1M with a T3/T4 ratio greater than 20. Treatment with anti-thyroid drugs (ATD) was carried out for 7Y and there was a progressive improvement in pain complaints 8M after starting ATD, allowing treatment with pamidronate to be discontinued. PLX4032 purchase Total thyroidectomy was performed at 12Y+5M.

This is a case of MAS-associated HT that reflects the deleterious effect of thyroid hormone excess on FD, reinforcing the need of having a low threshold for suspicion of HFE that may arise.

Salt stress is one of the critical factors affecting rice growth and yield. In this study, a tandem mass tag (TMT)-based comparative peptidomics analysis of rice seedlings under salt stress was conducted. Rice seedlings were exposed to 50 and 150 mM NaCl for 24 and 72 h, respectively, and the root and shoot tissues of different treatment groups were collected separately for peptidomics analysis. A total of 911 and 1263 nonredundant peptides were identified in two pooled shoot tissue samples, while there were 770 and 672 nonredundant peptides in two pooled root tissue samples, respectively. Compared with the control groups, dozens to hundreds of differentially expressed peptides (DEPs) were characterized in all treatment groups. To explore the potential functions of these DEPs, we analyzed the basic characteristics of DEPs and further analyzed the annotated Gene Ontology terms according to their precursor proteins. Several DEP precursor proteins were closely related to the response to salt stress, and some were derived from the functional domains of their corresponding precursors. The germination rate and cotyledon greening rate of transgenic Arabidopsis expressing two DEPs, OsSTPE2 and OsSTPE3, were significantly enhanced under salt stress. The described workflow enables the discovery of a functional pipeline for the characterization of the plant peptidome and reveals two new plant peptides that confer salinity tolerance to plants. Data are available via ProteomeXchange with identifier PXD037574.Pressure-induced structural transitions of the alkaline earth hexaborides, CaB6, SrB6, and BaB6, are studied theoretically using electron counting rules and density functional theory calculations. We demonstrate the applicability of gas-phase borane electron counting methods to solid-state metal borides under pressure and validate the assumptions of the rules by density functional theory (DFT) calculations. All three compounds share ambient-pressure and high-pressure structures, but BaB6 differs from CaB6 and SrB6 at intermediate pressures. The unique BaB6 phase is shown to break electron counting rules, while all other phases obey them. This anomaly is resolved by DFT, which reveals B-Ba covalency and unusual B-B π bonding under pressure. The relationships between structure and bonding can help us to understand the exotic behavior of lanthanide hexaborides and design new borides with desirable properties. Developing electron counting procedures for solids will enhance materials discovery efforts with chemical intuition.Dehydration has always been a confusing problem for a hydrogel exposed to air, which restricts its application in practical detection. While an ionogel with unique properties can lock water molecules efficiently due to its low vapor pressure, the design and development of an ionogel with excellent water-locking properties and stability to achieve satisfactory detection are thus highly desirable. In this work, a pH-sensitive, stretchable, antibacterial, and stable ionogel artificial tongue was fabricated through dual cross-linking. The artificial tongue consisted of MXene as a cross-linking agent, phenol red as an indicator, gelatin, N-(2-hydroxyethyl) acrylamide, and 1-butyl-3-methylimidazolium chloride as the three-dimensional polymer network. A small quantity of MXene was used as a cross-linker the first time to promote the initiator in the system to generate free radicals, accelerating the reaction process and the multilevel linkage among the polymers. Meanwhile, the indicator phenol red was introduced into the ionogel successfully for the first time, showing great stability in 5 weeks. After evaluation by the Brand-Altman analysis, it was found that the method of pH measurement using ionogels had good consistency with the pH meter measurement method. Additionally, the prepared ionogel presented excellent water retention, mechanical stretchability, antibacterial property, and stability, as well as good test results in the test of artificial simulated saliva, demonstrating great potential in clinical applications.A 92-year-old man presented with progressively worsening eye pain, diplopia on lateral gaze and blurred vision for the past 12 months. Radiological imaging confirmed a large left lacrimal gland lesion. The patient subsequently underwent a superio-lateral orbitotomy with left dacryoadenectomy and tumor removal, histopathology subsequently confirmed an epithelial-myoepithelial carcinoma arising ex pleomorphic adenoma of the lacrimal gland. Epithelial-myoepithelial carcinoma is a rare lacrimal gland tumour and the authors believe this case to be the first reported in the Australian population and associated with prolonged eye pain.Temple filler volumization can significantly improve facial balance and appearance, but has significant risks, including contour irregularities, vascular occlusion, skin necrosis, hair loss, blindness, stroke, and nonthrombotic pulmonary embolism. To improve the safety and precision of temple volumization, we have introduced ultrasound-guided injections of hyaluronic acid filler. We use the interfascial space as a target for our filler placement. We review relevant anatomy, including figures, describe a technique of ultrasound-guided filler injection in the interfascial plane with real-time visualization of the cannula and filler deposition, and include a detailed video of the procedure.Cryopreserving articular cartilage by vitrification can increase the availability of tissue for osteochondral allograft transplantation to treat cartilage defects. Developing well-optimized vitrification protocols can be supported by mathematical modeling to reduce the amount of trial-and-error experimentation needed. Fick's law has been used to model cryoprotectant diffusion, but it assumes ideal, dilute solution behavior, neglects water movement, and assumes diffusion of each cryoprotectant is independent of the presence of other cryoprotectants. The modified triphasic model addresses some of these shortcomings by accounting for water movement and the nonideal, nondilute nature of cryoprotectant vitrification solutions. However, it currently only exists for solutions containing a single cryoprotectant. As such, we extend the modified triphasic model to include two permeating cryoprotectants so that simultaneous diffusion occurring in vitrification protocols can be more accurately modeled. Using previously published experimental data, we determine suitable values for the fitting parameters of the new model. We then model a successful vitrification protocol for particulated cartilage cubes by calculating concentration, freezing point, vitrifiability, and strain profiles at the end of each loading step. We observe that Fick's law consistently underestimates cryoprotectant concentration throughout the cartilage compared to the modified triphasic model, leading to an underestimation of tissue vitrifiability. We additionally observe that simultaneous diffusion of cryoprotectants increases the permeation rate of each individual cryoprotectant, which Fick's law fails to consider. This suggests that using the two-cryoprotectant modified triphasic model to develop vitrification protocols could reduce excess exposure to cryoprotectants and improve preserved tissue outcomes.The urea oxidation reaction (UOR) is an excellent alternative to the sluggish oxygen evolution reaction (OER) as an anode reaction for hydrogen generation via electrochemical water splitting. Here, a porphyrin-based conjugated porous polymer (CPP) has been developed through the polycondensation reaction of 2,6-diformyl-4-methylphenol and pyrrole (DMP-POR). The nickel(II) complex of this conjugated polymer Ni-DMP-POR shows efficient UOR in an alkaline medium. The as-synthesized materials were characterized by solid-state 13C CP-MAS, thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The porous property of the materials was characterized by N2 adsorption/desorption isotherms at 77 K. Both DMP-POR and Ni-DMP-POR showed excellent thermal stability. The Ni-DMP-POR exhibits very good UOR in 1 M KOH and 0.33 M urea with an overpotential of 260 mV at 10 mA cm-2 and a Tafel slope of 48 mV dec-1. The catalyst also shows excellent chronoamperometric and chronopotentiometric stability, suggesting its future scope in sustainable hydrogen production from wastewater resources.

Safety and efficacy endpoints for the single-arm, multicenter, open-label pivotal study, CONtrolled Focal Fibrous Band Release Method (CONFFIRM) [NCT04743635] assessing Targeted Verifiable Subcision (TVS) for the treatment of cellulite were met at 3 months post-procedure and have been published. Final, 12 month data describing durability of treatment effect and safety are presented here for the first time.

To evaluate safety and efficacy out to 12 months of initial treatment for a single TVS procedure performed using the Avéli device (Revelle Aesthetics, Inc., Mountain View, CA) to treat cellulite on the buttock and thigh areas of adult females.

Effectiveness was determined by 3 independent physicians using the Cellulite Severity Scale (CSS) and Global Aesthetic Improvement Scale (GAIS) to assess improvement of baseline photographs when compared to 3-, 6- and 12-months posttreatment photographs. Blinded participant-reported outcomes (PROs) and safety evaluations were also performed at all post-procedure time points.

Clinically significant improvement in primary endpoint CSS scores were sustained out to 1 year, improving by 1.50 (p < .0001) at 3 months, 1.54 points at 6 months and 1.48 points at 12 months. Adverse events were mild and mostly resolved by the 12 month visit.

A single TVS treatment has durable efficacy and safety in reducing cellulite on the buttocks and thighs of women with moderate to severe cellulite out to 12 months posttreatment.
