What role does epigenetics play in sex differentiation in fish?5 answersEpigenetics plays a significant role in sex differentiation in fish. It serves as a bridge connecting the environment and genetics, influencing the interaction between the two factors. Epigenetic modifications, such as DNA methylation and histone modifications, are involved in various aspects of fish biology, including sex determination and differentiation. The establishment of the epigenetic profile in fish gametes during gametogenesis is crucial for transmitting epigenetic information to the offspring. Environmental factors, such as contaminants and domestication, can affect the epigenome of fish gametes, potentially leading to transgenerational effects. Additionally, epigenetic changes can be induced by the environmental conditions to which fish are exposed, such as water temperature and the presence of contaminants, and can result in altered gene expression and phenotypic changes. Understanding the epigenetic mechanisms underlying fish adaptation to environmental conditions is essential for studying fish farming and the impact of climate change on fish populations.
What are the challenges in binary image classification of larvae?5 answersBinary image classification of larvae faces several challenges. The data sets are often noisy, and the larvae themselves are deformable, projection-variant, and frequently in partial occlusion. Additionally, the images used in experiments lack texture information. These factors make it difficult to extract reliable shape features for classification. To overcome these challenges, researchers have proposed various methods such as using random sampling to construct stable classifiers and combining multiple classifiers for improved accuracy. Another approach involves developing new shape descriptors and using a normalized multilevel dominant eigenvector estimation method to select the best feature set for classification. Furthermore, the use of quantitative data obtained from processed digital images, along with a competitive learning vector quantization neural network, has shown promise in identifying larvae with high accuracy. These techniques aim to address the limitations of manual techniques and reduce inter- and intra-observer variability in larva classification.
What are the prevelant karyotypes of AML?4 answersAML is a heterogeneous disease with various karyotypes. The prevalent karyotypes in AML include t(15;17), t(8;21), inv(16)/t(16;16), and complex karyotypes. Trisomy 8 is the most frequent secondary change reported in APL cases with atypical cytogenetic features. Complex karyotypes in AML are associated with low response rates and frequent relapses. Patients with t(8;21), inv(16)/t(16;16), or t(15;17) have a favorable prognosis, while patients with complex karyotypes or specific aberrations have a poor prognosis. Complex karyotype anomalies, such as trisomy 1, 8, and 2, are associated with adverse prognosis in AML. Standard karyotype analysis at AML diagnosis can reveal prognostically important chromosomal translocations and large chromosome gains or losses in approximately half of AML patients.
