In such cases the main rule in establishing a final diagnosis is played by a physical examination with evaluation of sex development, as well as basic hormonal blood tests and karyotype result. Their correct interpretation is possible only by a physician who has reliable knowledge of the ...
We study a population of European grayling (Thymallus thymallusL.) that uses the pre-alpine lake Thun as its feeding habitat and spawns in spring at the outlet of this lake. A yearly monitoring program initiated in the 1940s revealed significantly distorted adult sex ratios (an excess of mal...
A leading model system for vertebrate skin patterning is the zebrafish; its alternating blue stripes and yellow interstripes depend on light-reflecting cells called iridophores. It was suggested that the zebrafish’s color pattern arises from a single type of iridophore migrating differentially to ...
It is known that tight junctions are characteristic features of differentiated airway epithelia and determine epithelial barrier as well as cell growth and differentiation. Extensive effort has been made to establish such methods of isolation and culture of human and other laboratory animal airway ...
Several reports have established that the action of neurotrophins is not restricted to the nervous system but can affect a broad range of non-neuronal cell... MA Russo,ML Giustizieri,A, Favale,... 被引量: 0发表: 2019年 Sex determination: insights from the chicken. Not all vertebrates shar...
Sex determination is the process deciding the sex of a developing embryo. This is usually determined genetically; however it is a delicate process, which in many cases can be influenced by environmental factors. The mechanisms controlling zebrafish sex determination and differentiation are not known. ...
Sex determination (SD) is a critical embryonic development process that has profound impacts on the morphology of individu- als and the survival of populations [1 ]. In vertebrates, sex can be determined by either genetic or environmental factors [21, with the underlying molecular mechanism unknown...
wheref(xbest)is the best likelihood found by maximum-likelihood (aka best fit objective function). This can be something like the sum of squared residuals (SSE).mis the number of parameters in your model.nis the number of data points used to fit your model. ...
Ki-67 labeling index assessed by immunohistochemical assays has been shown useful in assessing the risk of recurrence for estrogen receptor (ER)-positive H
p-Hydroxylcinnamaldehyde (CMSP) has been identified as an inhibitor of the growth of various cancer cells. However, its function in oesophageal squamous cell carcinoma (ESCC) and the underlying mechanism remain unclear. The aim of the present study was to characterize the differentiation effects of...
