In addition, adverse outcome pathway networks can provide a framework for organizing the available evidence/data for assessing chemical carcinogenicity. Since a formally accepted decision tree to guide use of the best and most current science to advance carcinogenicity risk assessment is currently unavailable, a Decision Matrix for carcinogenicity assessment could be useful. The workshop organizers developed and presented a decision matrix to be considered within a carcinogenicity hazard and risk assessment that is offered in tabular form.SignificanceThe modulation of growth hormone secretagogue receptor-1a (GHSR1a) signaling is a promising strategy for treating brain conditions of metabolism, aging, and addiction. GHSR1a activation results in pleiotropic physiological outcomes through distinct and pharmacologically separable G protein- and β-arrestin (βarr)-dependent signaling pathways. Thus, pathway-selective modulation can enable improved pharmacotherapeutics that can promote therapeutic efficacy while mitigating side effects. Here, we describe the discovery of a brain-penetrant small molecule, N8279 (NCATS-SM8864), that biases GHSR1a conformations toward Gαq activation and reduces aberrant dopaminergic behavior in mice. N8279 represents a promising chemical scaffold to advance the development of better treatments for GHSR1a-related brain disorders involving the pathological dysregulation of dopamine.SignificanceThe CD4+ Treg response following acute Listeria infection is heterogeneous and deploys two distinct modes of suppression coinciding with initial pathogen exposure and resolution of infection. This bimodal suppression of CD8+ T cells during priming and contraction is mediated by separate Treg lineages. These findings make a significant contribution to our understanding of the functional plasticity inherent within Tregs, which allows these cells to serve as a sensitive and dynamic cellular rheostat for the immune system to prevent autoimmune pathology in the face of inflammation attendant to acute infection, enable expansion of the pathogen-specific response needed to control the infection, and reestablish immune homeostasis after the threat has been contained.SignificanceDual-function RNAs base pair with target messenger RNAs as small regulatory RNAs and encode small protein regulators. However, only a limited number of these dual-function regulators have been identified. In this study, we show that a well-characterized base-pairing small RNA surprisingly also encodes a 15-amino acid protein. The very small protein binds the cyclic adenosine monophosphate receptor protein transcription factor to block activation of some promoters, raising the question of how many other transcription factors are modulated by unidentified small proteins.SignificanceWe introduce an approach to identify latent topics in large-scale text data. Our approach integrates two prominent methods of computational text analysis topic modeling and word embedding. We apply our approach to written narratives of violent death (e.g., suicides and homicides) in the National Violent Death Reporting System (NVDRS). Many of our topics reveal aspects of violent death not captured in existing classification schemes. We also extract gender bias in the topics themselves (e.g., a topic about long guns is particularly masculine). Our findings suggest new lines of research that could contribute to reducing suicides or homicides. Our methods are broadly applicable to text data and can unlock similar information in other administrative databases.SignificanceGenes on sex chromosomes (i.e. human chX) are regulated differently in males and females to balance gene expression levels between sexes (XY vs. XX). This sex-specific regulation is called dosage compensation (DC). DC is achieved by altering the shape and compaction of sex chromosomes specifically in one sex. In this study, we use Oligopaints to examine DC in silkworms. This study visualizes this phenomenon in a species with ZW sex chromosomes, which evolved independently of XY. Our data support a long-standing model for how DC mechanisms evolved across species, and we show potential similarity between DC in silkworms and nematodes, suggesting that this type of DC may have emerged multiple independent times throughout evolution.SignificanceMuch of online conversation today consists of signaling one's political identity. Although many signals are obvious to everyone, others are covert, recognizable to one's ingroup while obscured from the outgroup. Guggulsterone E&Z in vivo This type of covert identity signaling is critical for collaborations in a diverse society, but measuring covert signals has been difficult, slowing down theoretical development. We develop a method to detect covert and overt signals in tweets posted before the 2020 US presidential election and use a behavioral experiment to test predictions of a mathematical theory of covert signaling. Our results show that covert political signaling is more common when the perceived audience is politically diverse and open doors to a better understanding of communication in politically polarized societies.SignificanceEpidermal growth factor receptor (EGFR) is one of the most important membrane receptors that transduce growth signals into cells to sustain cell growth, proliferation, and survival. EGFR signal termination is initiated by EGFR internalization, followed by trafficking through endosomes, and degradation in lysosomes. How this process is regulated is still poorly understood. Here, we show that hepatocyte growth factor regulated tyrosine kinase substrate (HGS), a key protein in the EGFR trafficking pathway, is dynamically modified by a single sugar N-acetylglucosamine. This modification inhibits EGFR trafficking from endosomes to lysosomes, leading to the accumulation of EGFR and prolonged signaling. This study provides an important insight into diseases with aberrant growth factor signaling, such as cancer, obesity, and diabetes.SignificanceSurface engineering of halide perovskites (HaPs), semiconductors with amazing optoelectronic properties, is critical to improve the performance and ambient stability of HaP-based solar cells and light emitting diodes (LEDs). Ultrathin layers of two-dimensional (2D) analogs of the three-dimensional (3D) HaPs are particularly attractive for this because of their chemical similarities but higher ambient stability. But do such 2D/3D interfaces actually last, given that ions in HaPs move readily-i.e., what happens at those interfaces on the atomic scale? A special electron microscopy, which as a bonus also reveals the true conditions for nondestructive analysis, shows that the large ions that are a necessary part of the 2D films can move into the 3D HaP, a fascinating illustration of panta rei in HaPs.SignificanceWhile most small, regulatory RNAs are thought to be "noncoding," a few have been found to also encode a small protein. Here we describe a 164-nucleotide RNA that encodes a 28-amino acid, amphipathic protein, which interacts with aerobic glycerol-3-phosphate dehydrogenase and increases dehydrogenase activity but also base pairs with two mRNAs to reduce expression. The coding and base-pairing sequences overlap, and the two regulatory functions compete.SignificanceThis study uses large-scale news media and social media data to show that nationwide Black Lives Matter (BLM) protests occur concurrently with sharp increases in public attention to components of the BLM agenda. We also show that attention to BLM and related concepts is not limited to these brief periods of protest but is sustained after protest has ceased. This suggests that protest events incited a change in public awareness of BLM's vision of social change and the dissemination of antiracist ideas into popular discourse.Although immune checkpoint inhibitors (ICIs) have greatly improved cancer treatment, the accuracy of predictive biomarkers for ICI outcomes, such as PD-L1, TMB (tumor mutation burden) or MMR (mismatch repair) deficiency, have not been satisfactory. ARID family members are essential for maintaining the basic process of genomic stability and may serve as novel biomarkers for ICI therapy. A total of 1660 cancer patients who received ICI therapy were included in this pan-cancer analysis. The basic information and TMB values of each patient were collected. Survival analysis based on the Kaplan-Meier (KM) method was performed to explore the relationships between mutations in ARID family members and prognosis in pan-cancer as well as cancer subtypes. Genetic alterations in ARID1A (12%), ARID1B (5%), ARID2 (6%) and ARID5B (2.6%) were identified in multiple cancer types. Patients harboring mutated ARID family members benefited more from ICI therapy (P = .0003). Mutated ARID1A (P = .01), ARID1B (P = .0097) and ARID2 (P = .0054) all serve as compelling biomarkers in predicting the prognosis of ICI treatment. In addition, members of the ARID family were found to be strongly related to the abundance of CD4 + T cells and CD8 + T cells, the expression of PD-L1 and the TMB value in various cancers. Specifically, members of the ARID family could serve as novel biomarkers in multiple malignancies, especially gastrointestinal cancers. ARID family members serve as novel biomarkers for ICI therapy in malignancies. Testing the genomic status of ARID family members could help identify the definite subpopulation that benefits most from ICI treatment.Abbreviations AT-rich interactive domain (ARID)Switch/sucrose nonfermenting (SWI/SNF)Non-small cell lung cancer (NSCLC)Immune checkpoint inhibitors (ICIs)Tumor microenvironment (TME)Programmed death-ligand 1 (PD-L1)Tumor mutational burden (TMB).
To evaluate the different characteristics of oropharyngeal pH changes in patients with different laryngeal diseases.

A retrospective analysis was performed. The clinical data of 262 patients were summarized. The patients were divided into 4 groups. Group 1 included 123 patients with suspected laryngopharyngeal reflux disease (LPRD). Group 2 included 45 patients with vocal cord polyps. Group 3 included 40 patients with vocal cord leukoplakia. Group 4 included 54 patients with laryngeal carcinoma. Their reflux symptom indexes (RSIs), reflux finding scores (RFSs), and Dx-pH monitoring results were compared.

In total, 235 patients had abnormal RSI/RFS, 90 patients had abnormal Ryan scores. The rate of abnormal RSI/RFS of Group 1 was significantly higher than that of Group 4 (P = .001). Significant differences of the rates of abnormal Ryan scores existed between Groups 2 and 4 (P = .021) and Groups 3 and 4 (P = .027). There were obvious differences in upright Ryan scores between Groups 1 and 2 (P = .013), Gryngeal reflux may play different roles in different diseases through various patterns. Patients with vocal cord polyps, vocal cord leukoplakia, and laryngeal carcinoma had more and different patterns of oropharyngeal pH change than patients with LPRD. Patients with vocal cord polyps and vocal cord leukoplakia had more severe acid oropharyngeal pH change episodes than patients with laryngeal carcinoma.
Penile vascularized composite allotransplantation is a powerful tool for penile reconstruction. Traditional methods of reconstruction utilizing free tissue and prostheses have well-known complications, can require reoperation and cannot truly emulate the natural form or function of the penis. While vascularized composite allotransplantation may alleviate these difficulties, penile transplantation carries its own ethical, surgical and medical complications. To date, the procedure has only been attempted 5 times. Broader use of this procedure requires unique surgical considerations. We present the first comprehensive, detailed review of this procedure in order to present lessons learned from both our own and the global experience.

A review of published reports of penile transplant methods and outcomes was conducted to compile lessons learned from these cases.

Five penile transplant cases have been reported in literature, 4 with published methodology and outcomes data. All 4 detailed unique surgical approaches and postoperative immunosuppressive regimens.
