Progress in research on osteoporosis secondary to SARS‐CoV‐2 infection
Animal Models and Experimental Medicine, EarlyView.This review explores the potential mechanisms, complications, risk factors, and future research directions related to osteoporosis secondary to SARS‐CoV‐2 infection. Key mechanisms include an imbalance between osteoclast and osteoblast activity driven by direct viral effects on bone, inflammation, hypoxia, dysregulation of noncoding RNAs, and metabolic

Phosphatemia is an Independent Prognostic Factor in Amyotrophic Lateral Sclerosis
Annals of Neurology, EarlyView.Objective The objective of this study was to evaluate the prognostic value of several muscle damage biomarkers. Methods Data from Piemonte and Valle d'Aosta Amyotrophic Lateral Sclerosis (PARALS) were considered for this study. Survival was defined as the time from diagnosis to death, tracheostomy, or the censoring date.

The Anatomical Record, EarlyView.Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Hierarchical Phenotyping and Graph Modeling of Spatial Architecture in Lymphoid Neoplasms [PDF]
arXiv, 2021 The cells and their spatial patterns in the tumor microenvironment (TME) play a key role in tumor evolution, and yet the latter remains an understudied topic in computational pathology. This study, to the best of our knowledge, is among the first to hybridize local and global graph methods to profile orchestration and interaction of cellular components.

Automatic Detection of Blue-White Veil and Related Structures in Dermoscopy Images [PDF]
Computerized Medical Imaging and Graphics 32 (2008) 670-677, 2010 Dermoscopy is a non-invasive skin imaging technique, which permits visualization of features of pigmented melanocytic neoplasms that are not discernable by examination with the naked eye. One of the most important features for the diagnosis of melanoma in dermoscopy images is the blue-white veil (irregular, structureless areas of confluent blue ...

Studying the emergence of invasiveness in tumours using game theory [PDF]
, 2008 Tumour cells have to acquire a number of capabilities if a neoplasm is to become a cancer. One of these key capabilities is increased motility which is needed for invasion of other tissues and metastasis. This paper presents a qualitative mathematical model based on game theory and computer simulations using cellular automata.

Network-based community detection of comorbidities and their association with SARS-CoV-2 virus during COVID-19 pathogenesis [PDF]
arXiv, 2022 Recent studies emphasized the necessity to identify key (human) biological processes and pathways targeted by the Coronaviridae family of viruses, especially SARS-CoV-2. COVID-19 caused up to 33-55\% death rates in COVID-19 patients with malignant neoplasms and Alzheimer's disease.

JulianA: An automatic treatment planning platform for intensity-modulated proton therapy and its application to intra- and extracerebral neoplasms [PDF]
arXiv, 2023 Creating high quality treatment plans is crucial for a successful radiotherapy treatment. However, it demands substantial effort and special training for dosimetrists. Existing automated treatment planning systems typically require either an explicit prioritization of planning objectives, human-assigned objective weights, large amounts of historic ...

Deciphering the skeletal interoceptive circuitry to control bone homeostasis
BMEMat, EarlyView.This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).
