Influence of Super Absorbent Polymer (SAP) on Mechanical, Durability Properties, and Internal Curing Mechanism of Cement Stabilized Macadam in Desert Environment

Advances in Civil Engineering
Semi-rigid base materials in desert areas are susceptible to fast evaporation of water due to high-temperature and dry environment during construction and curing, leading to insufficient cement hydration and shrinkage cracking, thus affecting the ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Influence of post-fire recuring regimes on the properties of self-compacting concrete with heavyweight aggregate

Scientific Reports
Fire safety is essential in construction, as accidental fires subject concrete structures to high temperatures that result in significant damage.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

UV LED Curing for Silicone Hydrogel Contact Lenses: Breakthrough in Curing Properties and Cosmetic Characteristics

Polymers
Ultraviolet light-emitting diode (UV LED) technology offers advantages over conventional UV mercury (UV Hg) lamps, including precise wavelength control, high energy efficiency and rapid curing. While UV LED is widely applied in sectors like dentistry, printing, and electronics, its application in contact lens manufacturing remains relatively low.

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines

FEBS Open Bio, EarlyView.
Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.
