The role of aspirin in preventing gastrointestinal cancers.

Gastrointest Oncol (Phila)

October 2024

Institute for Clinical Trials and Methodology, University College London, London, UK.

Cancer remains an increasing global health issue and is projected to cause 50% of all global deaths by 2050. Gastrointestinal (GI) tract cancers currently account for approximately 25-30% of all cancer deaths. Consequently, there has been an emerging focus to optimize preventative measures for these cancers through varied avenues such as dietary change, public policy, screening/surveillance via endoscopy and most recently, chemoprevention.

Penile intraepithelial neoplasia (PeIN) and penile squamous cell carcinoma (PeSCC) are both thought to be associated with male genital lichen sclerosus and human papillomavirus (HPV) infection through dichotomous pathways: (i) undifferentiated PeIN and warty/basaloid PeSCC are thought to be HPV related, whereas (ii) differentiated PeIN and usual PeSCC are considered HPV independent. Tissue arrays were constructed from male genital lichen sclerosus, undifferentiated and differentiated PeIN, usual-type PeSCC, and unaffected tissues. Staining for p16 and for high-risk and low-risk HPV subtypes through RNAscope was performed.

Beyond Traditional Body Composition Metrics: Load-Capacity Indices Emerge as Predictors of Cardiometabolic Outcomes - A Systematic Review and Meta-Analysis.

Adv Nutr

January 2025

School of Population Health, Faculty of Health Science, Curtin University, Perth, WA, Australia; Dementia Centre of Excellence, Curtin enAble Institute, Faculty of Health Sciences, Curtin University, Perth, WA, Australia.

The adaptive and independent interrelationships between different body composition components have been identified as crucial determinants of disease risk. Based on this concept, the load-capacity model of body composition, which utilizes measurements obtained through non-anthropometric techniques such as dual-energy X-ray absorptiometry (DXA), was proposed. This model is typically operationalized as the ratio of metabolic load (adipose mass) to metabolic capacity (lean mass).

It is well known that the sedimentary rock record is both incomplete and biased by spatially highly variable rates of sedimentation. Without absolute age constraints of sufficient resolution, the temporal correlation of spatially disjunct records is therefore problematic and uncertain, but these effects have rarely been analysed quantitatively using signal processing methods. Here we use a computational process model to illustrate and analyse how spatial and temporal geochemical records can be biased by the inherent, heterogenous processes of marine sedimentation and preservation.

Recent years have seen unprecedented shifts in global natural gas trade, precipitated in large part by Russia's war on Ukraine. How this regional conflict impacts the future of natural gas markets is subject to three interconnected factors: (i) Russia's strategy to regain markets for its gas exports; (ii) Europe's push towards increased liquified natural gas (LNG) and the pace of its low carbon transition; and (iii) China's gas demand and how it balances its climate and energy security objectives. A scenario modelling approach is applied to explore the potential implications of this geopolitical crisis.

The incidence of cesarean section is dramatically increasing worldwide, whereas the training opportunities for obstetrician/gynecologists to manage complex cesarean section appear to be decreasing. This may be attributed to changing working hours directives and the increasing use of laparoscopy for gynecological surgical procedures, including in gynecological oncology. Various situations can create surgical difficulties during a cesarean section; however, two of the most frequent are complications from previous cesarean (myometrial defects, with or without placental intrusion and peritoneal adhesions) and the high risk of postpartum hemorrhage (uterine overdistension, abnormal placentation, uterine fibroids).

KAIST - Korea Advanced Institute of Science and Technology, Department of Chemistry, Center for Nanomaterials and Chemical Reaction, IBS, 373-1, Guseong Dong, Yuseong Gu, 305-701, Daejeon, KOREA, REPUBLIC OF.

Understanding how TiO2 interacts with CO2 at the molecular level is crucial in the CO2 reduction toward value-added energy sources. Here, we report in-situ observations of the CO2 activation process on the reduced TiO2(110) surface at room temperature using ambient pressure scanning tunneling microscopy. We found that oxygen vacancies (Vo) diffuse dynamically along the bridging oxygen (Obr) rows of the TiO2(110) surface under ambient CO2(g) environments.
