Polysaccharide‐Coated ETCA Nanoparticles Containing the Methoxyl Substituted Indole‐Thiazole Derivative and Their Antiproliferative Activity in Breast Cancer Cells

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Indole and thiazole derivatives have garnered significant attention due to their potent antitumor activities. Encapsulation of such derivatives into polymeric nanoparticles offers several advantages, including improved molecular stability and targeted delivery to tumor sites, thereby enhancing their antineoplastic potential.

Bacterial diversity and biopotentials of Hamtah glacier cryoconites, Himalaya

open access: yesFrontiers in Microbiology
Cryoconite is a granular structure present on the glaciers and ice sheets found in polar regions including the Himalayas. It is composed of organic and inorganic matter which absorb solar radiations and reduce ice surface albedo, therefore impacting the ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

open access: yesThe Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Rock debris on glaciers: a mechanism for reducing glacier sensitivity to climate change [PDF]

open access: yes, 2012
Rock debris covering a glacier surface affects the local melt rate by regulating the amount of solar energy available for melting. Supraglacial debris with a thickness of about 2 cm or more insulates the ice, thereby reducing the heat flux.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Offshore evidence for volcanic landslide post Last Glacial Maximum at sub-Antarctic Heard Island, southern Indian Ocean

open access: yesVolcanica
Heard Island, an active sub-Antarctic intraplate volcanic island on the Kerguelen Plateau, is mostly covered by glaciers. The amphitheatre shaped summit of the active volcanic centre, Big Ben (2813 m), has been interpreted to be the product of a ...

Fire Histories and Rainforest Aboriginal Archaeology in the Wet Tropics Bioregion, North Queensland

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Unlike the dominant Australian savanna‐sclerophyll vegetation, tropical rainforests do not burn easily. Any evidence of fire in Australian rainforests therefore invites explanations of its source. Analysis of 187 radiocarbon dates that include selected charcoal fragments from 23 soil pits and 7 archaeological sites from the Wet Tropics ...
