Sex assignment in conditions affecting sex development [PDF]

, 2017
The newborn infant with atypical genitalia presents a challenging clinical scenario and requires expert input. There have been appreciable advances in our knowledge of the underlying causes that may lead to a mere difference or a more serious disorder of

The unusual rainbow trout sex determination gene hijacked the canonical vertebrate gonadal differentiation pathway

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Sex determination is one of the most fundamental but also extraordinary plastic processes in nature. Many different master sex-determining genes have been characterized in vertebrates, and most of them are known to fulfill essential ...

Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

FEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Identification of Sex-Dependent Aroma Compounds in Gonads of Commercially Valuable Sea Urchins: Implications for Gastronomical Use of Paracentrotus lividus

Journal of Marine Science and Engineering
Background: The edible gonads of the sea urchin Paracentrotus lividus are highly valued, yet sex cannot be determined externally, limiting selective harvest and quality control.

Transcriptome display during tilapia sex determination and differentiation as revealed by RNA-Seq analysis

BMC Genomics, 2018
BackgroundThe factors determining sex in teleosts are diverse. Great efforts have been made to characterize the underlying genetic network in various species. However, only seven master sex-determining genes have been identified in teleosts.

Identifying gene expression signatures for risk stratification of postoperative adjuvant chemotherapy in colorectal cancer

FEBS Open Bio, EarlyView.
A novel signature integrating genome‐wide analysis with clinical factors predicts recurrence in stage II colorectal cancer and enables a new risk stratification to guide postoperative adjuvant chemotherapy. Clinical risk stratification for postoperative recurrence in patients with pathological stage II (pStage II) colorectal cancer (CRC) is essential ...

Frailty Exacerbates Disability in Progressive Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background To evaluate frailty in severe progressive multiple sclerosis (PMS) and to investigate the underlying mechanisms. Methods This prospective, cross‐sectional, multicenter study enrolled a late severe PMS group requiring skilled nursing (n = 53) and an age, sex, and disease duration‐matched control PMS group (n = 53).

Effects of Exogenous Estrogen on the Differentiation and Development of the Right Oviduct in Female Chickens

The Journal of Poultry Science, 2002
On day 5 of incubation, 0.64mg of estradiol benzoate (EB) was administered to fertilized eggs to investigate its effects on the differentiation and development of the oviduct in female chickens.

Renal Subcapsular xenografing of human fetal external genital tissue - A new model for investigating urethral development. [PDF]

, 2017
In this paper, we introduce our novel renal subcapsular xenograft model for the study of human penile urethral and clitoral development. We grafted fifteen intact fetal penes and clitorides 8-11 weeks fetal age under the renal capsules of gonadectomized ...
