Epstein-Barr virus replication within differentiated epithelia requires pRb sequestration of activator E2F transcription factors.

Epstein-Barr virus (EBV) co-infections with human papillomavirus (HPV) have been observed in oropharyngeal squamous cell carcinoma. Modeling EBV/HPV co-infection in organotypic epithelial raft cultures revealed that HPV16 E7 inhibited EBV productive replication through the facilitated degradation of the retinoblastoma protein pRb/p105. To further understand how pRb is required for EBV productive replication, we generated CRISPR-Cas9 pRb knockout (KO) normal oral keratinocytes (NOKs) in the context of wild-type and mutant K120E p53.

A molecular metal-organic cage as a recyclable sponge for PFOS removal from water.

A metal-organic cage (MOC) is shown to be an efficient molecular sponge for PFOS. A large association constant is observed for the 2 : 1 PFOS : MOC host-guest complex. Up to 12 equivalents of PFOS per MOC are removed from water.

Community-based, inclusive design of a 3D tactile map to enable playground navigation for children who are visually impaired and blind.

The LSU Community Playground Project (LSUCPP) collaborates with communities (especially the true experts at play, the children) to design and build playgrounds that reflect "the soul of the community." One member of the LSUCPP undertook a research project in an effort to design better playgrounds for use by children who are visually impaired or blind. A recommendation from this research was to provide a 3D-printed tactile map of each play area, such that children who were visually impaired or blind could feel the location and type of equipment and ground surfaces prior to entering a playground, which would enable them to play independently.

ENGOT-en11/GOG-3053/KEYNOTE-B21: a randomised, double-blind, phase III study of pembrolizumab or placebo plus adjuvant chemotherapy with or without radiotherapy in patients with newly diagnosed, high-risk endometrial cancer.

Background: Pembrolizumab plus chemotherapy provides clinically meaningful benefit as first-line therapy for advanced (locoregional extension and residual disease after surgery)/metastatic/recurrent mismatch repair-proficient (pMMR) and mismatch repair-deficient (dMMR) endometrial cancer, with greater magnitude of benefit in the dMMR phenotype. We evaluated the addition of pembrolizumab to adjuvant chemotherapy (with/without radiation therapy) among patients with newly diagnosed, high-risk endometrial cancer without any residual macroscopic disease following curative-intent surgery.

Methods: We included patients with histologically confirmed high-risk [International Federation of Gynecology and Obstetrics (FIGO) stage I/II of non-endometrioid histology or endometrioid histology with p53/TP53 abnormality, or stage III/IVA of any histology] endometrial cancer following surgery with curative intent and no evidence of disease postoperatively, with no prior radiotherapy or systemic therapy.

Characterization, Phylogenetic Analyses, and Pathogenicity of on Sorghum in China.

Sorghum, the fifth-largest cereal crop globally and a C4 crop, mainly grows in arid and semiarid areas. In 2021 to 2023, a new foliar disease of sorghum occurred in China. The diseased leaves showed water-soaked symptoms in the leaf tip and margins, resulting in half- and full-leaf desiccation and necrosis, thus affecting plant photosynthesis.

Experimentally Assessing the Electronic Structure and Spin-State Energetics in MnFe Dimers Using 1s3p Resonant Inelastic X-ray Scattering.

The synergistic interaction between Mn and Fe centers is investigated via a comprehensive analysis of full 1s3p resonant inelastic X-ray scattering (RIXS) planes at both the Fe and Mn K-edges in a series of homo- and heterometallic molecular systems. Deconvolution of the experimental two-dimensional 1s3p RIXS maps provides insights into the modulation of metal-ligand covalency and variations in the metal multiplet structure induced by subtle electronic structural differences imposed by the presence of the second metal. These modulations in the electronic structure are key toward understanding the reactivity of biological systems with active sites that require heterometallic centers, including MnFe purple acid phosphatases and MnFe ribonucleotide reductases.

Subjective and objective sleep quality assessment in adolescent patients with inflammatory bowel disease.

Objectives: There is a link between inflammatory bowel disease (IBD) and poor sleep quality that is presumed to be multifactorial. The purpose of this study was to identify factors that impact sleep quality in this group including clinical disease activity, depression, anxiety, quality of life, and disordered social media use through questionnaires.

Methods: This prospective study analyzed sleep quality in adolescent patients ages 13 to 18 with a diagnosis of IBD using objective data from wrist actigraphy and subjective report from the Pittsburgh Sleep Quality Index (PSQI).

Octomacrum spinum (Monogenoidea: Polyopisthocotylea: Octomacridae) from highland stoneroller, Campostoma spidaceum (Cypriniformes: Leuciscidae) from Arkansas and Oklahoma, USA, with a summary of the genus from North American and European fishes.

Octomacrum spinum Dansby & Shoemaker, 1973, is reported for the first time from 23 of 146 (16%) highland stonerollers, Campostoma spadiceum collected from central and western Arkansas and southeastern Oklahoma, USA. Analysis of molecular data revealed that the SSU rRNA gene of specimens of O. spinum from Arkansas was identical to a number of Octomacrum spp.

Whole-Genome Omics Elucidates the Role of CCM1 and Progesterone in Cerebral Cavernous Malformations within CmPn Networks.

Cerebral cavernous malformations (CCMs) are abnormal expansions of brain capillaries that increase the risk of hemorrhagic strokes, with CCM1 mutations responsible for about 50% of familial cases. The disorder can cause irreversible brain damage by compromising the blood-brain barrier (BBB), leading to fatal brain hemorrhages. Studies show that progesterone and its derivatives significantly impact BBB integrity.

Employing Raman Spectroscopy and Machine Learning for the Identification of Breast Cancer.

Background: Breast cancer poses a significant health risk to women worldwide, with approximately 30% being diagnosed annually in the United States. The identification of cancerous mammary tissues from non-cancerous ones during surgery is crucial for the complete removal of tumors.

Results: Our study innovatively utilized machine learning techniques (Random Forest (RF), Support Vector Machine (SVM), and Convolutional Neural Network (CNN)) alongside Raman spectroscopy to streamline and hasten the differentiation of normal and late-stage cancerous mammary tissues in mice.

Reconstructive evolutionary morphology: Tracing the historical process of modifications of complex systems driven by natural selection through changing ecological conditions.

There is general consensus among evolutionary biologists that natural selection drives phenotypic modifications within populations over generational time. How to reconstruct this historical process, however, has been discussed mostly in theoretical terms, and recommendations and explanations on how to translate such theoretical insights into practice are needed. The present study aims at providing a theory-supported practical guide on how to reconstruct historical evolutionary processes by applying a morphology-centered approach through a series of interdependent steps of descriptive morphology, functional analysis, ecological observation, integration of paleoecological data, and evolutionary synthesis.

Preclinical Female Model of Urogenital Dysfunction and Pathophysiological Changes After Pelvic Radiation Therapy.

Introduction Radiation therapy (RT) is the gold standard for many pelvic cancers and improves overall patient survival. However, pelvic RT is associated with increased sexual dysfunction and urinary incontinence. Although the side effects of pelvic RT are well-documented, the pathological mechanisms leading to pelvic organ dysfunction are unknown, and a preclinical model has not been established.

History and future of leptin: Discovery, regulation and signaling.

The cloning of leptin 30 years ago in 1994 was an important milestone in obesity research. Prior to the discovery of leptin, obesity was stigmatized as a condition caused by lack of character and self-control. Mutations in either leptin or its receptor were the first single gene mutations found to cause severe obesity, and it is now recognized that obesity is caused mostly by a dysregulation of central neuronal circuits.
