Semiconductor snail lasers [PDF]

open access: yesApplied Physics Letters, 2010
A modified ring laser geometry is presented to promote stable unidirectional lasing. The effects of directional coupling and facet reflectivities are investigated with respect to quantum efficiency, directionality, and side-mode suppression ratio of the lasing spectra. Simulation and experimental results are presented showing single mode (>20 dB

Report of rotifer-ciliate-gastropod hyperepibiosis found on snail (Mollusca) from Goa, India

open access: yesActa Biologica, 2021
Here we report a rotifer-ciliate-gastropod hyperepibiosis in freshwater canal, Goa, India. A rotifer Philodina cf. megalotrocha Ehrenberg, 1832 was found attached on the colony of Epistylis plicatilis Ehrenberg, 1838 which was epibiont on gastropod ...

Analytic representation of the generalized Pascal snail and its applications [PDF]

open access: yesarXiv, 2020
We find an unifying approach to the analytic representation of the domain bounded by a generalized Pascal snail. Special cases as Pascal snail, Both leminiscate, conchoid of the Sluze and a disc are included. The behavior of functions related to generalized Pascal snail are demonstrated.

Dose‐dependent induction of epithelial‐mesenchymal transition in 3D melanoma models by non‐thermal plasma treatment

open access: yesMolecular Oncology, EarlyView.
Non‐thermal plasma treatment of melanoma cells induced epithelial‐mesenchymal transition (EMT) in a dose‐dependent fashion. This report highlights the critical need to further investigate potential adverse effects of non‐thermal plasma for cancer therapy and to optimize treatment parameters for clinical translation. Despite the promising results of non‐

Effects of snails, submerged plants and their coexistence on eutrophication in aquatic ecosystems

open access: yesKnowledge and Management of Aquatic Ecosystems, 2017
Eutrophication resulting from nutrient loading to freshwater habitats is a severe problem, leading to degradation of ecosystems, including deterioration of water quality, water clarity and loss of biodiversity.

JNK‐mediated Ser27 phosphorylation and stabilization of SIRT1 promote growth and progression of colon cancer through deacetylation‐dependent activation of Snail

open access: yesMolecular Oncology, 2022
Sirtuin 1 (SIRT1), an NAD+‐dependent histone/protein deacetylase, has multifaceted functions in various biological events such as inflammation, aging, and energy metabolism. The role of SIRT1 in carcinogenesis, however, is still under debate.

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

Liquid Crystalline Networks Hamper the Malignancy of Cancer Cells

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Liquid Crystalline Networks are used as scaffolds for the growth of A375 melanoma cells demonstrating to affect their malignancy. Indeed, only by contact, these materials reduces cell proliferation and colony formation capacity, while increasing the number of senescent cells and promoting the mesenchymal to epithelial transition.

Lichen Endozoochory by Snails

open access: yesPLoS ONE, 2011
Endozoochory plays a prominent role for the dispersal of seed plants. However, for most other plant taxa it is not known whether this mode of dispersal occurs at all. Among those other taxa, lichens as symbiotic associations of algae and fungi are peculiar as their successful dispersal requires movement of propagules that leaves the symbiosis ...

Electric Field Driven Soft Morphing Matter

open access: yesAdvanced Materials, EarlyView.
This study presents soft morphing matter robots that exhibit extremely high morphological adaptability and complex multimodal electric field response. They can undergo large, controlled body deformation and show complex locomotion on different terrains under the manipulation of external electric fields, making a significant step beyond current ...
