Trichogerminoma (TG) is a rare adnexal tumor with hair follicle differentiation with less than 50 cases reported in the literature. In 2022, by investigating the genetic profile of 21 cases, our group identified recurrent rearrangements of the GRHL1/2/3 genes in this tumor entity, suggesting such alteration as the main oncogenic driver in TG. Up to now, only one TG case of malignant transformation has been reported.

Chlamydia muridarum (Cm) has reemerged as a moderately prevalent infectious agent in research mouse colonies. Despite its experimental use, few studies evaluate Cm's effects on immunocompetent mice following its natural route of infection. A Cm field isolate was administered (orogastric gavage) to 8-wk-old female BALB/cJ (C) mice.

Enhancing Photodynamic Therapy Efficacy via Photo-Triggered Calcium Overload and Oxygen Delivery in Tumor Hypoxia Management.

ACS Appl Mater Interfaces

January 2025

Department of Ultrasound, National Clinical Research Center for Child Health and Disorders, Ministry of Education Key Laboratory of Child Development and Disorders, Chongqing Engineering Research Center of Stem Cell Therapy, Children's Hospital of Chongqing Medical University, Chongqing 400010, China.

: Photodynamic therapy (PDT) has emerged as a promising treatment for cancer, primarily due to its ability to generate reactive oxygen species (ROS) that directly induce tumor cell death. However, the hypoxic microenvironment commonly found within tumors poses a significant challenge by inhibiting ROS production. This study aims to investigate the effect of improving tumor hypoxia on enhancing PDT.

Lysosomal stress due to the accumulation of nucleic acids (NAs) activates endosomal TLRs in macrophages. Here, we show that lysosomal RNA stress, caused by the lack of RNase T2, induces macrophage accumulation in multiple organs such as the spleen and liver through TLR13 activation by microbiota-derived ribosomal RNAs. TLR13 triggered emergency myelopoiesis, increasing the number of myeloid progenitors in the bone marrow and spleen.

Triple-negative breast cancer (TNBC) is a highly metastatic subtype of breast cancer. The epithelial-to-mesenchymal transition is a nonbinary process in the metastatic cascade that generates tumor cells with both epithelial and mesenchymal traits known as hybrid EM cells. Recent studies have elucidated the enhanced metastatic potential of cancers featuring the hybrid EM phenotype, highlighting the need to uncover molecular drivers and targetable vulnerabilities of the hybrid EM state.

The Effector Protease FgTPP1 Suppresses Immune Responses and Facilitates Fusarium Head Blight Disease.

Mol Plant Microbe Interact

January 2025

USDA-ARS Crop Production and Pest Control Research Unit, West Lafayette, Indiana, United States;

Most plant pathogens secrete effector proteins to circumvent host immune responses, thereby promoting pathogen virulence. One such pathogen is the fungus , which causes Fusarium Head Blight (FHB) disease on wheat and barley. Transcriptomic analyses revealed that expresses many candidate effector proteins during early phases of the infection process, some of which are annotated as proteases.

Focal therapy (FT) is an emerging option for intermediate-risk prostate cancer (IR-PCa). Transperineal MRI fusion laser ablation of PCa (TPFLA) is a novel FT technique with limited data reported. We conducted a phase I clinical trial evaluating the safety, feasibility, and 1-year oncologic results for patients with IR-PCa treated with TPFLA in an office setting.

Background: The COVID-19 pandemic prompted researchers to develop new ways to design and launch studies and recruit and retain participants. Pregnant women and infants are considered vulnerable populations in research, and families affected by substance use are particularly difficult to recruit and retain. Recruitment for studies involving medical technologies such as MRI can also be difficult due to misconceptions and fear of the technologies.

Evaluation of Local Tumor Outcomes Following Microwave Ablation of Colorectal Liver Metastases Using CT Imaging: A Comparison of Visual versus Quantitative Methods.

Radiol Imaging Cancer

January 2025

From the Department of Radiology, Royal Marsden Hospital NHS Foundation Trust, 203 Fulham Road, London SW3 6JJ, England (J.D.S., L.K., L.P., J.M., N.K., D.M.K., E.J.); Institute of Cancer Research, London, England (N.P., D.M.K.); and Department of Radiology and Nuclear Medicine, Rijnstate Hospital, Arnhem, the Netherlands (W.O.).

Purpose To compare visual versus quantitative ablation confirmation for identifying local tumor progression and residual tumor following microwave ablation (MWA) of colorectal liver metastases (CRLM). Materials and Methods This retrospective study included patients undergoing MWA of CRLM from October 2014 to February 2018. Two independent readers visually assessed pre- and postprocedure images and semiquantitatively scored for incomplete ablation, using a six-point Likert scale, and extracted quantitative imaging metrics of minimal ablative margin (MAM) and percentage of tumor outside of the ablation zone, using both rigid and deformable registration.

The Ross procedure continues to be the best procedure to address unrepairable aortic valve pathology, especially in young adults. The Achilles heel of this procedure has been aortic root dilation and the potential need for a reoperation that may be associated with slightly increased risks in addition to the need for intervention on the pulmonary outflow tract. Modifying the Ross procedure by autograft inclusion inside a Dacron graft seems to have the potential advantage of stabilizing the autograft diameter, which may be associated with improved durability and decrease the need for future intervention.

Purpose: The present study assessed the test-retest reliability of the American Sign Language (ASL) version of the Computerized Revised Token Test (CRTT-ASL) and compared the differences and similarities between ASL and English reading by Deaf and hearing users of ASL.

Method: Creation of the CRTT-ASL involved filming, editing, and validating CRTT instructions, sentence commands, and scoring. Deaf proficient (DP), hearing nonproficient (HNP), and hearing proficient sign language users completed the CRTT-ASL and the English self-paced, word-by-word reading CRTT (CRTT-Reading-Word Fade [CRTT-R-wf]).

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal malignancy of the gastrointestinal tract. Most GIST harbor mutations in oncogenes, such as KIT, and are treated with tyrosine kinase inhibitors (TKI), such as imatinib. Most tumors develop secondary mutations inducing drug resistance against the available TKI, which requires novel therapies.

Plaque brachytherapy has been used in the management of small to medium-sized choroidal melanomas for the past few decades. As the inferior oblique muscle lies in close relation to the macula, the placement procedure of plaques often involves sacrificing the inferior oblique muscle, especially in cases of macular or perimacular choroidal melanomas. In this study, we have described a simple maneuver to preserve the inferior oblique muscle.

Introduction: Though the research on the quality of life of people who stutter is extensive, there is minimal research on cluttering's life impact. Anecdotal reports from people who clutter and their significant others have described some elements of cluttering's impact and advocated for these components to be addressed in treatment. Three formal studies have used semistructured interviews to document cluttering's impact.
