Effects of a saponin fraction extracted from Trigonella foenum-graecum L. and two commercially available saponins on sex ratio and gonad histology of Nile tilapa fry, Oreochromis niloticus (L.) [PDF]

open access: yes, 2013
Over three million tonnes (t) of tilapia, mostly Nile tilapia (Oreochromis niloticus, L.), are produced annually making it the second most abundantly produced freshwater fish (FAO, 2010).

Postembryonic RNAi in Heterorhabditis bacteriophora: a nematode insect parasite and host for insect pathogenic symbionts [PDF]

open access: yes, 2007
Background: Heterorhabditis bacteriophora is applied throughout the world for the biological control of insects and is an animal model to study interspecies interactions, e.g. mutualism, parasitism and vector-borne disease. H. bacteriophora nematodes are

Revising Fascial Anatomy With a Focus on the Fusion Fascia in Mesenteric Gastrointestinal Cancer Surgery

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This review critically reassesses our prior hypothesis and proposes a revised anatomical model of the fusion fascia that is broadly applicable to GI cancer surgeries grounded in the principles of mesenteric resection. Our synthesis suggests that the fusion fascia is neither a dense connective tissue membrane nor a remnant of mesothelial fusion, but ...

Dynamic testing for evaluation of adrenal and gonadal function in pediatric and adult endocrinology: An overview

open access: yesIndian Journal of Endocrinology and Metabolism, 2019
Dynamic tests are often considered as the backbone of endocrinology. These tests involve the use of an exogenous agent to manipulate the body's hormonal milieu for the diagnosis and characterization of an endocrine disorder.

Syndrome of the Month: An Update on Smith‐Kingsmore Syndrome: Characterization of Developmental Milestones and a Review of the Literature

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Smith‐Kingsmore syndrome (SKS) is a rare autosomal dominant condition characterized by neurodevelopmental differences, macrocephaly/megalencephaly, describable facial features, sleep–wake abnormalities, hyperphagia, and overgrowth. SKS is caused by pathogenic gain‐of‐function variants in MTOR which lead to hyperactivation of the mTOR pathway ...

Brain Gender and Transsexualism [PDF]

open access: yes, 2007
Research by neuroscientists suggests there is a distinction in the BSTc area of the brain between males and females. In transsexual females, those considered male at birth, but who had a strong conviction that they were female, the BSTc region appears to

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.

Low‐Level Mosaicism in Tuberous Sclerosis Complex (TSC): Diagnostic and Clinical Implications From Two Novel Cases and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mosaicism is relatively common in Tuberous Sclerosis Complex (TSC) but can be difficult to detect using routine diagnostic tests, particularly when the variant allele frequency (VAF) is low. We describe two cases of mosaic TSC diagnosed using an ultra‐deep sequencing approach in multiple tissues and review the literature about this topic in ...

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.

Complete Androgen Insensitivity Syndrome: Role of Imaging for Diagnosis

open access: yesIndian Journal of Radiology and Imaging
Androgen insensitivity syndrome (AIS) is a rare disorder of sexual differentiation, characterized by impaired responsiveness to androgens, resulting in the development of typically female external genitalia, despite having a male chromosomal pattern (XY).
