Time to Diagnosis Among Children and Adolescents With Cancer in Québec, Canada: A Population‐Based Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely cancer diagnosis in children and adolescents is important to improving outcomes. We aimed to quantify time to diagnosis and assess variations by patient, demographic and system‐level factors. Procedure We conducted a population‐based study of individuals aged 0–19 years diagnosed with one of 12 cancers from 2010 to 2022 in ...

Malignant Ovarian Mixed Germ Cell Tumor: a Rare Case [PDF]

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2009
Background and Objectives: Mixed germ cell tumors of the ovary, uncommon but aggressive tumors are seen most often in young women or adolescent girls, and are generally curable if found and treated early.

Tumores testiculares na infância

open access: yesRevista do Colégio Brasileiro de Cirurgiões
Testicular and paratesticular prepuberal tumors are rare. They represent around 1% of the total of tumors of infancy. They subdivide in 2 groups: germ cells tumors and non germ cells tumors, being able to occur in all the ages, and about 75% are ...

Extragonadal germ cell tumors

open access: yesAnnals of Oncology, 2002
Germ cell cancer is the most common malignancy in men aged 15–35 years; 5% of the malignant germ cell tumors are of extragonadal origin [1]. An extragonadal germ cell tumor (EGGCT) is by definition a germ cell neoplasm displaying one of the histologies associated with gonadal origin, but located outside of the gonads.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

CT features of mature teratoma in the mediastinum of two young adults—a report of two cases

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2020
Background Germ cell tumors prefer gonadal regions, but they can be expected in extragonadal sites such as the anterior mediastinum, which is the commonly involved region after gonads.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Ovary: Germ cell tumors [PDF]

open access: yesAtlas of Genetics and Cytogenetics in Oncology and Haematology, 2011
Note Ovarian germ cell tumours (OGCT) are a type of ovarian neoplasm principally affecting young women. They are derived from primitive germ cells of the embryonic gonad, and may undergo germinomatous or embryonic differentiation. They differ in clinical presentation, histology and biology, and include both benign (predominantly) and malignant subtypes.

Zebrafish Germ Cell Tumors [PDF]

open access: yes, 2016
Germ cell tumors (GCTs) are malignant cancers that arise from embryonic precursors known as Primordial Germ Cells. GCTs occur in neonates, children, adolescents and young adults and can occur in the testis, the ovary or extragonadal sites. Because GCTs arise from pluripotent cells, the tumors can exhibit a wide range of different histologies.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
