A multimetric health literacy analysis of phalloplasty techniques: Comparing artificial intelligence and online resources.

Background: This study aims to compare the informational quality of online and artificial intelligence (AI) - sources on different phalloplasty donor sites to assess reliability and accessibility.

Methods: A deidentified Google search was conducted using search phrases for forearm, thigh, back, and abdomen phalloplasty. The first ten websites for each donor site were included.

Variability in Postoperative Nipple Sensation by Dermoglandular Pedicle in Bilateral Breast Reduction.

Background: Decreased nipple sensation following reduction mammoplasty can negatively affect a variety of patient-centered outcomes. This observational study examined the impact of dermoglandular pedicle type on subjective postoperative nipple sensation.

Methods: A total of 178 women who underwent a bilateral reduction mammoplasty at a single institution from 2017 to 2023 and completed an 11-item survey assessing subjective postoperative nipple sensitivity across various tactile modalities were included.

Complications after gender-affirming chest masculinization surgery do not impact patient satisfaction.

Chest masculinization surgery is an increasingly common procedure and has offered significant benefits to the gender-diverse community. Although major complications are an infrequent occurrence in chest masculinization surgery, they may still impact surgical success. While the long-term success of chest masculinization surgery has been examined through patient-reported outcome measures, there is no study that has assessed the association between complications and patient-reported outcomes.

Impact of sternal notch-to-nipple distance and resection weight asymmetry on complication rates and patient reported outcomes in reduction mammaplasty.

While there are numerous predictive models for estimating resection weight, their accuracy may not be strong. Through institutional data of patients who received reduction mammaplasty, this study demonstrates that preoperative sternal notch-to-nipple distance is not an optimal predictive factor for differences in final resection weight, complication rates, and patient reported outcomes. Our results showed that there is a weak correlation between preoperative sternal notch to nipple asymmetry and final resection weight asymmetry.

Approach to High-Nitrogen Materials with Dual-Use Properties via Tetraaza-Nazarov Cyclization.

In this report, we describe the application of an electrocyclization toward the synthesis of a high-nitrogen heterocycle. It entails the synthesis of a novel, high-nitrogen, 2-3-disubstituted tetrazolium salt via the tetraaza-Nazarov cyclization (4π electrocyclization) of 3-bromo-1,5-bis(3-nitro-1,2,4-triazole-1-5-yl)-formazan (BDNF). The cyclization takes place under mild conditions using the oxidant phenyliodine(III) diacetate (PIDA).

Heterocyclic Nitrilimines and Their Use in the Synthesis of Complex High-Nitrogen Materials.

We show the ability of a nitrilimine prepared from 3-amino-5-nitro-1,2,4-triazole to undergo various cyclization and rearrangement reactions, giving a beautiful diversity of nitrogen-rich heterocyclic products. This chemistry includes the first cyclization of a nitrilimine with a diazonium species, giving a tetrazole, a previously unknown transformation, as well as leading to the creation of several new energetic materials with backbones not available by traditional techniques. New materials prepared were characterized both chemically (multinuclear NMR, IR, mass spectrometry, and elemental analysis) and energetically, with sensitivities and performances reported.

Tetrazole Azasydnone (C N O H) And Its Salts: High-Performing Zwitterionic Energetic Materials Containing A Unique Explosophore.

This work reports the first compound containing both a tetrazole and an azasydnone ring, a unique energetic material. Several energetic salts of the tetrazole azasydnone were synthesized and characterized, leading to the creation of new secondary and primary explosives. Molecular structures are confirmed by H and C NMR, IR spectroscopy, and X-ray crystallographic analysis.

Apico-basal forces exerted by apoptotic cells drive epithelium folding.

Epithelium folding is a basic morphogenetic event that is essential in transforming simple two-dimensional epithelial sheets into three-dimensional structures in both vertebrates and invertebrates. Folding has been shown to rely on apical constriction. The resulting cell-shape changes depend either on adherens junction basal shift or on a redistribution of myosin II, which could be driven by mechanical signals.

JNK signalling controls remodelling of the segment boundary through cell reprogramming during Drosophila morphogenesis.

Segments are fundamental units in animal development which are made of distinct cell lineages separated by boundaries. Although boundaries show limited plasticity during their formation for sharpening, cell lineages make compartments that become tightly restricted as development goes on. Here, we characterize a unique case of breaking of the segment boundary in late drosophila embryos.

The Drosophila serine protease homologue Scarface regulates JNK signalling in a negative-feedback loop during epithelial morphogenesis.

In Drosophila melanogaster, dorsal closure is a model of tissue morphogenesis leading to the dorsal migration and sealing of the embryonic ectoderm. The activation of the JNK signal transduction pathway, specifically in the leading edge cells, is essential to this process. In a genome-wide microarray screen, we identified new JNK target genes during dorsal closure.

A complex systems model approach to quantified mineral resource appraisal.

For federal and state land management agencies, mineral resource appraisal has evolved from value-based to outcome-based procedures wherein the consequences of resource development are compared with those of other management options. Complex systems modeling is proposed as a general framework in which to build models that can evaluate outcomes. Three frequently used methods of mineral resource appraisal (subjective probabilistic estimates, weights of evidence modeling, and fuzzy logic modeling) are discussed to obtain insight into methods of incorporating complexity into mineral resource appraisal models.

Practices and perceptions of food safety among seniors who prepare meals at home.

Given senior citizens' vulnerability for food-borne illness, a need exists to determine the necessity and focus for education. Focus groups at senior centers reveal that the seniors (N=74) who prepare more than five meals a week at home use both inappropriate and appropriate practices to cook, cool, and thaw foods. Seniors rely of the distant past for knowledge and identify barriers to altering practices but state that information from educators about the health effects of inappropriate practices will convince them to change.

Magma Beneath Yellowstone National park.

The Yellowstone plateau volcanic field is less than 2 million years old, lies in a region of intense tectonic and hydrothermal activity, and probably has the potential for further volcanic activity. The youngest of three volcanic cycles in the field climaxed 600,000 years ago with a voluminous ashflow eruption and the collapse of two contiguous cauldron blocks. Doming 150,000 years ago, followed by voluminous rhyolitic extrusions as recently as 70,000 years ago, and high convective heat flow at present indicate that the latest phase of volcanism may represent a new magmatic insurgence.
