Precursor cells of the vulva of the C. elegans hermaphrodite choose between two vulval cell fates (1 degree and 2 degrees) and a non-vulval epidermal fate (3 degrees) in response to three intercellular signals. An inductive signal produced by the anchor cell induces the vulval precursors to assume the 1 degree and 2 degree vulval fates. This inductive signal is an EGF-like growth factor encoded...

To gain insights into the mechanisms of cell fate decision in a noisy environment, the effects of intrinsic and extrinsic noises on cell fate are explored at the single cell level. Specifically, we theoretically define the impulse of Cln1/2 as an indication of cell fates. The strong dependence between the impulse of Cln1/2 and cell fates is exhibited. Based on the simulation results, we illustr...

Introduction: The fate of xenobiotics that is present, increasing day by day. The increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. Methods: The present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by Panax ginse...

Neural crest forms four major categories of derivatives: pigment cells, peripheral neurons, peripheral glia, and ectomesenchymal cells. Some early neural crest cells generate progeny of several fates. How specific cell fates become specified is still poorly understood. Here we show that zebrafish embryos with mutations in the colourless gene have severe defects in most crest-derived cell types,...

This paper explores the phase space structures characterising transport for a double-well van der Waals potential surface. Trajectories are classified as inter-well, intra-well, and escaping-from-a-well to define different dynamical fates. In particular, roaming trajectories, which new paradigm in chemical reaction dynamics, observed. We apply method of Lagrangian descriptors uncover boundaries...

The stable maintenance of acquired cell fates is important during development and for maintaining tissue homeostasis. Although histone modification is one of the major strategies used by cells to maintain their fates, the mechanisms by which histone variants maintain cell fates are not well understood. In C. elegans, the acetylated-histone-H4 (AcH4)-binding protein BET-1 acts downstream of the ...

In this paper, we present soliton-like solutions of the non-linear complex Klein-Gordon systems in 1+1 dimensions. We will use polar representation to introduce three different soliton-like solutions including, complex kinks (anti-kinks), radiative profiles, and localized wave-packets. Complex kinks (anti-kinks) are topological objects with zero electrical charges. Radiative profiles are object...
