Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

open access: yesFEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Fecundity of Otolithes ruber (Scneider, 1801) in Khuzestan Coastal Waters

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1998
To study on fecundity of O. ruber, in spawning season, 31 samples caught in Khouzestan waters on Feb. 1996 to April 1997 were examined, and gravimetry method was used. Maximum absolute fecundity were 1483369 ± 14409 and 81726± 1831 eggs respectively, and

Habitat quality, configuration and context effects on roe deer fecundity across a forested landscape mosaic.

open access: yesPLoS ONE, 2019
Effective landscape-scale management of source-sink deer populations will be strengthened by understanding whether local variation in habitat quality drives heterogeneity in productivity.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Genetic and Environmental (Co)variation of Egg Size, Fecundity, and Growth Traits in Arctic Charr

open access: yesEvolutionary Applications
Egg size and fecundity are both positively associated with maternal reproductive success, yet maternal resource limitations result in a trade‐off between these two traits.

On the fecundity of the Black Sea bream, Spondyliosoma cantharus (L. ), from the Adriatic Sea (Croatian coast)

open access: yesScientia Marina, 1998
The fecundity of the Black Sea bream from the eastern middle Adriatic (Croatian coast) was assessed by the volumetric method using 59 ovaries in pre-spawning stage from fish between 18.5 and 33.5 cm total length.

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

High-glucose diets differentially modulate phosphatidylcholine metabolism and fecundity in Caenorhabditis elegans

open access: yesFrontiers in Cell and Developmental Biology
BackgroundCaenorhabditis elegans fed a high-glucose Escherichia coli OP50 diet exhibit reduced fecundity, but the underlying mechanisms remain unclear.MethodsA differential high-glucose diet paradigm was established using C.

High‐Temperature Phase Transformation in a V‐9Si‐6.5B Alloy: The Kinetic and Crystallographic Pathway From V5SiB2 to V8SiB4

open access: yesAdvanced Engineering Materials, EarlyView.
In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.
