Primary borderline mucinous neoplasm of the testis: A case report and literature review
Indian Journal of Urology, 2012 Testicular/paratesticular neoplasms morphologically resembling surface epithelial tumors of ovarian type are rare neoplasms. The criteria for the diagnosis and nomenclature of these tumors parallels those used for ovarian homologues.

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.

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.

Kinetic theory of Hyaluronan cleavage by Bovine Testicular Hyaluronidase in Standard and Crowded Environments [PDF]
arXiv, 2020 ${\bf Background}$ Details of the kinetic pathways governing enzymatic cleavage of hyaluronic acid (HA) by hyaluronidase are still widely uncharted. Capillary electrophoresis-based assays were used for accurate quantification of enzymatic products. A crowding agent was also employed to mimic excluded-volume constraints typical of in-vivo conditions. $

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.

Sonographic detection of occult testicular neoplasms.
AJR. American journal of roentgenology, 1982 Testicular sonograms were performed in four patients with pathologically proven metastatic neoplasms but a normal physical examination of the scrotum. An abnormal echo texture was seen in all cases: focal hypoechoic nodule (about 1 cm) in two, diffusely ...

Environmental Toxicology, Volume 38, Issue 1, Page 225-242, January 2023., 2023 Abstract Per‐ and polyfluoroalkyl substances (PFAS), which include perfluorooctanoic acid (PFOA), heptafluorobutyric acid (HFBA), and perfluorotetradecanoic acid (PFTA), are commonly occurring organic pollutants. Exposure to PFAS affects the immune system, thyroid and kidney function, lipid metabolism, and insulin signaling and is also involved in the ...

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 ...
