Functional maturation of the gonads of Turkish hamsters under various photoperiods [PDF]

open access: yesBiology of Reproduction, 1986
The golden hamster, Mesocricetus auratus, is the only photoperiodic rodent to date that has been shown to fail to respond to inhibitory (i.e., short, less than 12.5 h/day) photoperiods until after pubertal onset. In other photoperiodic hamsters, mice, and voles, short photoperiods greatly retard gonadal maturation.

Classical gonadoblastoma: its relationship to the “dissecting” variant and undifferentiated gonadal tissue [PDF]

open access: yes, 2017
Classical gonadoblastoma occurs almost entirely in the dysgenetic gonads of an individual who has a disorder of sex development. Approximately 40% of such neoplasms are bilateral.

Genetic Abnormalities and Clinical Management of Fetal Genitourinary System Anomalies in Eastern China

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT To investigate the correlation between genetic abnormalities and fetal genitourinary (GU) anomalies in Eastern China and to provide assistance for the clinical management of fetuses with different types of GU anomalies. Five hundred forty‐five fetuses with GU anomalies were enrolled, undergoing karyotyping, copy number variation sequencing ...

Group-synchronous ovarian development, spawning and spermiation in the European sea bass (Dicentrarchus labrax L.) could be regulated by shifts in gonadal steroidogenesis

open access: yesScientia Marina, 2002
European sea bass (Dicentrarchus labrax L.) is a species with group-synchronous ovarian development. A mechanism is required which enables maturation to occur in the first clutches of oocytes without inducing maturation in subsequent clutches.

Estimates of body sizes at maturation and at sex change, and the spawning seasonality and sex ratio of the endemic Hawaiian grouper (Hyporthodus quernus, F. Epinephelidae) [PDF]

open access: yes, 2011
A case study of the reproductive biology of the endemic Hawaiian grouper or hapu’upu’u (Hyporthodus quernus) is presented as a model for comprehensive future studies of economically important epinephelid groupers.

The 9th International RASopathies Symposium

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.

Combined Long‐Read Genome and Transcriptome Sequencing Establishes Novel Variants in MEGF8 as the Cause for Carpenter Syndrome Type 2

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Carpenter syndrome type 2 (CRPT2) is a rare autosomal recessive disease mainly characterized by craniosynostosis and polysyndactyly. CRPT2 is the rarer subtype of Carpenter syndrome (CRPTS) and is caused by biallelic variants in the multiple epidermal growth factor‐like domains 8 gene (MEGF8).

Biochemical Changes during Gonadal Maturation Portunus pelagicus (Linnaeus, 1758) [PDF]

open access: yes, 2010
The changes in moisture, protein, lipid, carbohydrate and carotenoids in the ovary, hepatopancreas, muscle and haemolymph during the process of gonadal maturation of the crab PorhmllS pelagiclls (Linnaeus, 1758) were nvestigated.

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

Determination of maturation and spawning season of Otolithes ruber (Croaker Fish) in Khuzestan coastal water, Iran

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1998
In this study, the stage of gonadal development, type and season of spawning of Otolithes ruber in the North West of Persian Gulf were identified. O.ruber maturation and spawning were studied by macroscopic, microscopic, and histologic observation of ...
