Increased Expression of miR‐326 Mediates Chemosensitivity in Pediatric Acute Lymphoblastic Leukemia Through ABCA2 and YY1 Downregulation: An Observational and Experimental Study

Health Science Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background and Aims Multidrug resistance (MDR) is a major determinant of relapse‐associated mortality in pediatric acute lymphoblastic leukemia (pALL). Although miR‐326 downregulation has been associated with poor prognosis, its role in chemoresistance remains undefined. This study investigated the mechanistic contribution of miR‐326 to MDR in

Natural and anthropogenic rapid changes in the Kara-Bogaz Gol over the last two centuries reconstructed from palynological analyses and a comparison to instrumental records

, 2006
Palynological analyses (pollen and dinocysts) of a sediment core taken in the Kara-Bogaz Gol have been used to reconstruct rapid and catastrophic environmental changes over the last two centuries (chronology based on 210Pb).

Temperature‐driven diet shift in an invasive omnivorous crustacean feeding on plankton

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Global warming alters the physiology of ectotherm consumers, potentially making their diets more herbivorous. However, the relevance and generality of these changes remain poorly understood in a multispecies context. To address this critical knowledge gap, we experimentally tested the temperature‐dependent feeding preference of the invasive ...

Sea ice phenology in the Caspian Sea

Advances in Oceanography and Limnology, 2021
To understand the spatial and temporal variations in the extent and timing of sea ice in the Caspian Sea (CS), 15 years of sea ice presence and its phenology (freeze-up, break-up, and duration) were studied in the Northern CS (NCS) for a period from 2004 to 2018.

New organic-walled dinoflagellate cysts from recent sediments of central Asian seas

, 2004
Recent to sub-recent sediments from the Caspian Sea, the Kara-Bogaz-Gol Bay, the Enseli lake and the Aral Sea contain the new organic-walled dinoflagellate cysts Caspidinium, Caspidinium rugosum and Impagidinium caspienense.

Expanding known dinoflagellate distributions: Investigations of slurry cultures from Caspian Sea sediment [PDF]

, 2017
To investigate the disparity between plankton and cyst records, sediment slurry cultures were used to isolate the motile stage of dinoflagellates from Caspian Sea sediment.

Effects of Norbixin on Growth Performance, Immunomodulation, Antioxidant Systems, and Metabolic Alterations in the Oriental River Prawn (Macrobrachium nipponense): An Integrative Analysis

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Dietary norbixin (0.15 g/kg) optimally promotes growth, immunocompetence, antioxidant defence, gut microbial balance, carotenoid accumulation, and overall nutritional quality in Macrobrachium nipponense. ABSTRACT Background Natural carotenoids have gained considerable attention in aquaculture due to their potential to enhance growth performance ...
