Perspectives are provided on an alternative career path in regulatory science for those currently involved in basic biology research. This path is compared and contrasted with basic research, and factors to be examined if one is considering such a path are discussed.

The common ancestor and evolution by natural selection, concepts introduced by Charles Darwin, constitute the central core of biology research and education. However, students generally struggle to understand these concepts and commonly form misconceptions about them. To help teachers select the most revelant portions of Darwin's work, I suggest some sentences from On the Origin of Species and briefly discuss their implications. I also suggest a teaching strategy that uses history of science and curriculum crosscutting concepts (cause and effect) that constitute the framework to explain the evolutionary history of ratites (flightless birds) as described by Darwin, starting in the Jurassic, with the breakup of Gondwanaland, as first described by Alfred Wegener in The Origin of Continents and Oceans.

More and more basic biology research focus on the single cell level. However, the way to fabricate a chemically patterned surface exist some questions such as complex fabrication process, graphic quality puzzle and so on. In this paper, we present a One-Step method based on Poly 2-hydroxyethyl methacrylate (PolyHEMA) and micromolding in capillaries (MIMIC) technology to fabricate single cell culture chip. Experimental evidence indicates that the integrity and stability of the PolyHEMA pattern can perfectly satisfy the need of long-term cell culture.

Much of the spectacular progress in biomedical science over the last half-century is the direct consequence of the work of thousands of basic scientists whose primary goal was understanding of the fundamental working of living things. Despite this, many politicians, funders, and even scientists have come to believe that the pace of successful applications to medical diagnosis and therapy is limited by our willingness to focus directly on human health, rather than a continuing deficit of understanding. By this theory, curiosity-driven research, aimed at understanding, is no longer important or even useful. What is advocated instead is “translational” research aimed directly at treating disease. I believe this idea to be deeply mistaken. Recent history suggests instead that what we have learned in the last 50 years is only the beginning. The way forward is to invest more in basic science, not less.

Liver regeneration in mammals is a unique phenomenon attracting scientific interest for decades. It is a valuable model for basic biology research of cell cycle control as well as for clinically oriented studies of wide and heterogeneous group of liver diseases. This article provides a concise review of current knowledge about the liver regeneration, focusing mainly on rat partial hepatectomy model. The three main recognized phases of the regenerative response are described. The article also summarizes history of molecular biology approaches to the topic and finally comments on obstacles in interpreting the data obtained from large scale microarray-based gene expression analyses.

AbstractDetermining the binding locations of regulatory factors, such as transcription factors and histone modifications, is essential to both basic biology research and many clinical applications. Obtaining such genome-wide location maps directly is often invasive and resource-intensive, so it is common to impute binding locations from DNA sequence or measures of chromatin accessibility. We introduce DeepATAC, a deep-learning approach for imputing binding locations that uses both DNA sequence and chromatin accessibility as measured by ATAC-seq. DeepATAC significantly outperforms current approaches such as FIMO motif predictions overlapped with ATAC-seq peaks, and models based only on DNA sequence, such as DeepSEA. Visualizing the input importances for the DeepATAC model reveals DNA sequence motifs and ATAC-seq signal patterns that are important for predicting binding events. The Keras implementation and analysis pipelines of DeepATAC are available at https://github.com/hiranumn/deepatac.

ABSTRACT Objective. Growth and mortality parameters of Cachana Cynopotamus atratoensis Eigenmann, 1907 in the cienaga Grande de Lorica, Sinu river basin, Colombia, were estimated. Materials and methods. The length frequency analysis to the information collected between January 2001 to December 2002, was applied. Results. The estimated values for asymptotic length, growth rate and age at zero length were 43.4 (±0.52) cm of total length, 0.29 (±0.02) year-1 and -0.53 years, respectively. Total mortality was estimated at 0.97 year-1, natural mortality at 0.72 year-1, fishing mortality at 0.25, the average catch size was 24.8 cm total length, being fully recruited to the fishery with 16.6 cm total length, with low exploitation rate (E: 0.26). Conclusions. Cachana is a fish with medium longevity and growth rate with low exploitation rate, suggesting that there is still no overfishing on the species. However, as it is an very important fish in the food security of fishermen and their families, its necessary to increase the basic biology research pointing to the management and conservation of the species in the cienaga and the Sinu basin.

INTRODUCTION: Schistosomiasis has been described as “one of the most devastating diseases of mankind, second only to malaria in its deleterious effects on the social and economic development of populations in many warm areas of the world.” The disease is worldwide and is probably spreading faster and becoming more intense than the overall research efforts designed to provide the basis for countering it. Moreover, there are indications that the development of water resources and the demands for increasing cultivation and food in developing countries may prevent adequate control of the disease and thus the number of infections are increasing.Our knowledge of the basic biology of the parasites causing the disease is far from adequate. Such knowledge is essential if we are to develop a rational approach to the effective control of human schistosomiasis. The miracidium is the first infective stage in the complex life cycle of schistosomes. The future of the entire life cycle depends on the capacity and ability of this organism to locate and enter a suitable snail host for further development, Little is known about the nervous system of the miracidium of Schistosoma mansoni and of other trematodes. Studies indicate that miracidia contain a well developed and complex nervous system that may aid the larvae in locating and entering a susceptible snail host (Wilson, 1970; Brooker, 1972; Chernin, 1974; Pan, 1980; Mehlhorn, 1988; and Jones, 1987-1988).
