Introduction: There is a lack of qualitative analysis of the personal experiences within Couples Matching. In this qualitative study, we aim to record personal attitudes, reflections, and advice on experiences with the Couples Match process.

Methods: Our survey, consisting of two open-ended questions regarding the experience of Couples Matching, was distributed from January 2022 to March 2022 via email to 106 otolaryngology program directors across the nation.

Background: Grade Group 1 (GG1) prostate cancer should be managed with active surveillance (AS). Global uptake of AS remains disappointingly slow and heterogeneous. Removal of cancer labels has been proposed to reduce GG1 overtreatment.

The common terminology criteria for adverse events by the National Cancer Institute has greatly facilitated the revolution of drug development and an increasing number of Phase I trials have started to collect multiple-grade toxicity endpoints. Appropriate and yet transparent Phase I statistical designs for multiple-grade toxicities are therefore in great needs. In this article, we propose a quasi-toxicity probability interval (qTPI) design that incorporates a quasi-continuous measure of the toxicity probability () into the Bayesian theoretic framework of the interval based designs.

We report the self-assembly of amphiphilic BDQ photosensitizers into lysosome-targeting nanophotosensitizer BDQ-NP for highly effective photodynamic therapy (PDT). Molecular dynamics simulation, live cell imaging, and subcellular colocalization studies showed that BDQ strongly incorporated into lysosome lipid bilayers to cause continuous lysosomal membrane permeabilization. Upon light irradiation, the BDQ-NP generated a high level of reactive oxygen species to disrupt lysosomal and mitochondrial functions, leading to exceptionally high cytotoxicity.

The synthesis and magnetic properties of two pairs of isomeric, exchange-coupled complexes, [LnCl(TiCp)] (Ln = Gd, Tb), are reported. In each isomeric pair, the central lanthanide ion adopts either a pseudo-octahedral (O-Ln) or trigonal prismatic geometry (TP-Ln) yielding complexes with or molecular symmetry, respectively. Ferromagnetic exchange coupling is observed in TP-Ln as indicated by the increases in below 30 K.

The structure of the bony labyrinth is highly informative with respect to locomotor agility (semicircular canals [SCC]) and hearing sensitivity (cochlear and oval windows). Here, we reconstructed the agility and hearing sensitivity of the stem lagomorph from the early Oligocene of the Brule Formation of Nebraska (USA). has proportionally smaller SCCs with respect to its body mass compared with most extant leporids but within the modern range of variability, suggesting that it was less agile than most of its modern relatives.

Article Synopsis
  • High valent iron terminal imido species (Fe=NR) are important for C-H functionalization, but detailed studies on their structure-reactivity relationships and the effects of N-substituents are limited.
  • This study presents insights from spectroscopic and computational analyses of a unique iron(IV)-bisimido complex with trifluoromethyl groups that shows distinct electronic properties compared to related complexes.
  • The findings indicate that the electronic structure of this complex enhances its efficiency in C-H activation, offering advantages over similar complexes with less reactive grounding states.

Highly strained cage hydrocarbons have long stood as fundamental molecules to explore the limits of chemical stability and reactivity, probe physical properties, and more recently as bioactive molecules and in materials discovery. Interestingly, the nitrogenous congeners have attracted much less attention. Previously absent from the literature, azahomocubanes, offer an opportunity to investigate the effects of a nitrogen atom when incorporated into a highly constrained polycyclic environment.

The main-chain poly[]catenane consists of a series of interlocked rings that resemble a macroscopic chain-link structure. Recently, the synthesis of such intriguing polymers was reported a metallosupramolecular polymer (MSP) template that consists of alternating units of macrocyclic and linear thread-like monomers. Ring closure of the thread components has been shown to yield a mixture of cyclic, linear, and branched poly[]catenanes.

Environmental heterogeneity in temperate latitudes is expected to maintain seasonally plastic life-history strategies that include the tuning of morphologies and metabolism that support overwintering. For species that have expanded their ranges into tropical latitudes, it is unclear the extent to which the capacity for plasticity will be maintained or will erode with disuse. The migratory generations of the North American (NA) monarch butterfly lead distinctly different lives from their summer generation NA parents and their tropical descendants living in Costa Rica (CR).

Tropical regions harbor a substantial diversity of lichenized fungi, but face numerous threats to their persistence, often even before previously unknown species have been described and their evolutionary relationships have been elucidated. (Ramalinaceae) is a lichen-forming genus of fungi that produces crustose thalli, and includes a number of lineages occupying tropical rain forests; however, taxonomic and phylogenetic work on this clade is limited. Here we leverage both morphological and sequence data to describe a new species from the tropics, .

We report the case of a 33-year-old man with a self-inflicted neck wound with severe hypopharynx injury, and hemorrhagic shock, which was well managed by a trauma surgeon trained in esophageal surgery. Training in cervical lymph node dissection for esophageal cancer could be useful in the management of penetrating neck injuries.

Article Synopsis
  • - Benign prostate hyperplasia and prostate cancer both involve excessive growth of prostate tissue, highlighting the need to understand the normal progenitor cells in the prostate and identify potential drug targets.
  • - Researchers used single-cell RNA sequencing (scRNA-Seq) to identify a specific population of luminal progenitor cells in the prostate of mice, both with and without hormonal treatment.
  • - The study found key factors essential for regenerating prostate organoids from mice and humans, suggesting scRNA-Seq can help uncover potential pharmacologic strategies aimed at the cell populations responsible for prostate diseases.

Article Synopsis
  • - The T1-REQUIRE algorithm is introduced as a proof-of-concept tool that estimates T1 relaxation times in the brain using T1-weighted MRIs, improving the quantification of tissue damage for better clinical assessments.
  • - Validation studies show that T1-REQUIRE correlates well with established reference standards and maintains consistency across different MRI sequences, achieving high Lin's concordance correlation coefficients.
  • - The algorithm effectively standardizes data from multiple MRI scanners, enhancing the uniformity of T1-relaxation maps and suggesting it could be valuable for large-scale data analysis in medical imaging.

Carpal tunnel syndrome is the most common upper extremity peripheral neuropathy syndrome. Treatment ranges from nonsurgical methods, including night-orthosis fabrication and corticosteroid injections to surgical management via a carpal tunnel release (CTR). Carpal tunnel release alleviates nerve compression by releasing the transverse carpal ligament, and performed as either an open CTR (OCTR) or endoscopic CTR (ECTR) procedure.

How does the public decide who is deserving of welfare benefits? To shed light on this question, we investigate whether the CARIN principles of deservingness-specifically the ideas of control, attitude, reciprocity, identity, and need-impact the public's perception of American welfare target groups. We draw contrast between traditional welfare programs and pandemic-related programs to gain a more comparative understanding of the principles' effects as well as to determine what role the pandemic may play in shaping welfare perceptions. We report that positive, deserving social constructions exist for recipients of both traditional and pandemic-related welfare programs, and we find evidence that the distinction between traditional and pandemic-related programs is important for deservingness perceptions in the US.
