The "backdoor pathway" of androgen synthesis in human male sexual development. [PDF]

open access: yes, 2019
Mammalian sex determination (male versus female) is largely controlled by genes, whereas sex differentiation (development of reproductive structures) is largely controlled by hormones. Work in the 20th century indicated that female external anatomy was a

In vivo differentiation of scarring alopecia using line‐field confocal optical coherence tomography: a pilot study

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background and Objectives: Diagnosing cicatricial alopecia is challenging. Even with histology, a definitive diagnosis cannot always be made. Line‐field confocal optical coherence tomography (LC‐OCT), a non‐invasive imaging method with high resolution used in vivo, has proven helpful in diagnosing scarring alopecia.

In vitro androgenetic cultures of Hyoscyamus niger L., H. albus L. and alkaloid content assay

open access: yesActa Societatis Botanicorum Poloniae, 2014
In vitro cultures of Hyoscyamus niger L. and H. albus L. anthers were initiated which resulted in obtaining androgenectic plants and callus cultures. The leaves of these pants and the callus cultures were subjected to analysis (TLC, GC for the presence ...

Study of individual plant responsiveness in anther cultures of selected pepper (Capsicum spp.) genotypes

open access: yesFolia Horticulturae, 2012
One of the key factors determining the effectiveness of pepper anther cultures is donor plant genotype. The stock material for androgenic embryos inductions is usually made up of hybrid forms, since the higher the degree of heterozygosity, the greater ...

Rapid attainment of a doubled haploid line from transgenic maize ( Zea mays L.) plants by means of anther culture [PDF]

open access: yes, 2018
Summary: We present a strategy for establishing a transgenic doubled haploid maize line from heterozygous transgenic material by means of anther culture. Compared to conventional inbreeding, the in vitro androgenesis technique enables a faster generation

Formation and excretion of autophagic plastids (plastolysomes) in Brassica napus embryogenic microspores

open access: yesFrontiers in Plant Science, 2015
The change in developmental fate of microspores reprogrammed towards embryogenesis is a complex but fascinating experimental system where microspores undergo dramatic changes derived from the developmental switch.

Advantages of horizontal centrifugation of platelet‐rich fibrin in regenerative medicine and dentistry

open access: yesPeriodontology 2000, EarlyView.
Abstract The aim of this comprehensive review was to evaluate comparative studies on horizontal and fixed‐angle centrifugation methods for preparing platelet‐rich fibrin (PRF). Furthermore, additional studies utilizing horizontal PRF (H‐PRF) were systematically investigated.
