Imaging of disorder of sex development

Annals of Saudi Medicine, 2013
Disorders of sex development (DSDs), formerly termed ambiguous genitalia, are a group of conditions where the external genitalia appear abnormal. It represents a true medical and social emergency that needs a multidisciplinary team approach for elucidation.

A Bayesian analysis of current duration data with reporting issues: an application to estimating the distribution of time-between-sex from time-since-last-sex data as collected in cross-sectional surveys in low- and middle-income countries [PDF]

arXiv, 2023
Aggregate measures of family planning are used to monitor demand for and usage of contraceptive methods in populations globally, for example as part of the FP2030 initiative. Family planning measures for low- and middle-income countries are typically based on data collected through cross-sectional household surveys.

Unveiling the Significance of the Androgen Receptor Gene in Disorders of Sex Development

Advances in Human Biology
Disorders of sex development (DSD) encompass a range of congenital conditions where the development of chromosomal, gonadal or anatomical sex is atypical. There are many genes associated with DSD, and one of them is the androgen receptor (AR) gene, which

A Study on Lampreys Population Based on Sex-Ratio-Related Growth-Balance Model [PDF]

Transactions on Computational and Applied Mathematics. 2024 May 6;4(1):48-55
Lampreys are one of the oldest species in the world, living longer than dinosaurs, which is related to the ability to change the sex ratio during their lifespan. In this paper, to understand how sex ratio and food quantity affect the population growth rate of lampreys, the researchers draw inspiration from the logistics model and established a model ...

Performance of mutation pathogenicity prediction tools on missense variants associated with 46,XY differences of sex development [PDF]

Clinics
OBJECTIVES: Single nucleotide variants (SNVs) are the most common type of genetic variation among humans. High-throughput sequencing methods have recently characterized millions of SNVs in several thousand individuals from various populations, most of ...

Mitochondrial DNA disorders in neuromuscular diseases in diverse populations

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Neuromuscular features are common in mitochondrial DNA (mtDNA) disorders. The genetic architecture of mtDNA disorders in diverse populations is poorly understood. We analysed mtDNA variants from whole‐exome sequencing data in neuromuscular patients from South Africa, Brazil, India, Turkey and Zambia. In 998 individuals, there were two definite

Transverse testicular ectopia with disorders of sex development

Indian Journal of Urology, 2012
Transverse testicular ectopia (TTE) is a rare congenital anomaly. Although TTE often coexists with abnormalities such as inguinal hernia and persistent Mullerian duct syndrome, disorders of sex development (DSD) in combination with TTE is extremely rare.

Detecting non-binomial sex allocation when developmental mortality operates [PDF]

arXiv, 2016
Optimal sex allocation theory is one of the most intricately developed areas of evolutionary ecology. Under a range of conditions, particularly under population sub-division, selection favours sex being allocated to offspring non-randomly, generating non-binomial variances of offspring group sex ratios.

Calcium modulating ligand confers risk for Parkinson's disease and impacts lysosomes

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Objective Several genetic loci known to confer risk for Parkinson's disease (PD) function in lysosomal pathways. We systematically screened common variants linked to PD risk by genome‐wide association studies (GWAS) for impact on cerebrospinal fluid (CSF) proteins reflecting lysosomal function.

A Dual Role for Sex? [PDF]

arXiv, 2008
The two classic theories for the existence of sexual replication are that sex purges deleterious mutations from a population, and that sex allows a population to adapt more rapidly to changing environments. These two theories have often been presented as opposing explanations for the existence of sex.
