Germ cell tumor of ovary with plenty of sarcoid like granulomas: A diagnosis on fine needle aspiration cytology

open access: yesJournal of Cytology, 2012
Germ cell tumors of ovary with elements of two or more subtypes are relatively uncommon. Sarcoid-like granulomas are seen in rare association with dysgerminomas, a subgroup of germ cell tumors of ovary, which are again less common. Fine-needle aspiration

Defending the genome from the enemy within:mechanisms of retrotransposon suppression in the mouse germline [PDF]

open access: yes, 2013
The viability of any species requires that the genome is kept stable as it is transmitted from generation to generation by the germ cells. One of the challenges to transgenerational genome stability is the potential mutagenic activity of transposable ...

Novas perspectivas no diagnóstico do hipogonadismo pediátrico masculino: a importância do AMH como marcador de células de Sertoli [PDF]

open access: yes, 2011
Sertoli cells are the most active cell population in the testis during infancy and childhood. In these periods of life, hypogonadism can only be evidenced without stimulation tests, if Sertoli cell function is assessed.

Interpreting the dependence of mutation rates on age and time [PDF]

open access: yes, 2015
Mutations can arise from the chance misincorporation of nucleotides during DNA replication or from DNA lesions that are not repaired correctly. We introduce a model that relates the source of mutations to their accumulation with cell divisions, providing

Intracranial germ cell tumor

open access: yesJournal of the Belgian Society of Radiology, 2010
Germ cell tumours represent about 3 to 8% of pediatric brain tumours. Occurrence of diabetes insipidus is common in the case of suprasellar germ cell tumors. The diagnosis may be advanced by MRI owing to the location and relatively univocal characteristics of the lesion signal.

Endocrine disrupters, microRNAs, and primordial germ cells: a dangerous cocktail [PDF]

open access: yes, 2016
29 p.-2 fig.Endocrine-disrupting chemicals (EDCs) are environmental pollutants that may change the homeostasis of the endocrine system, altering the differentiation of germ cells with consequences for reproduction.

A mitotic kinase scaffold depleted in testicular seminomas impacts spindle orientation in germ line stem cells. [PDF]

open access: yes, 2015
Correct orientation of the mitotic spindle in stem cells underlies organogenesis. Spindle abnormalities correlate with cancer progression in germ line-derived tumors.

Characterizing the zebrafish organizer: microsurgical analysis at the early-shield stage [PDF]

open access: yes, 1996
The appearance of the embryonic shield, a slight thickening at the leading edge of the blastoderm during the formation of the germ ring, is one of the first signs of dorsoventral polarity in the zebrafish embryo.
