Regulatory Effects of Betonica macrantha Extract, Known as Mountain Tea, on miRNA Expression and Its Pharmacokinetic Properties [PDF]

open access: yesFood Science &Nutrition, Volume 13, Issue 6, June 2025.
Betonica macrantha methanol extract exhibited anticancer activity against MDA‐MB‐231 breast cancer cells (IC50: 0.8 mg/mL), upregulating miR‐19, miR‐20a, miR‐126, and miR‐200c. GC–MS and HPLC analyses identified key bioactive compounds, including α‐pinene, caryophyllene, and catechin, which showed favorable pharmacokinetics and target interactions ...

In vitro metabolism study of ADB‐P‐5Br‐INACA and ADB‐4en‐P‐5Br‐INACA using human hepatocytes, liver microsomes, and in‐house synthesized references [PDF]

open access: yesDrug Testing and Analysis, Volume 17, Issue 5, Page 701-712, May 2025.
Analyzing hepatocytes and liver microsomes samples along with synthesized references. Complete structure elucidation of major metabolites was possible, and biomarkers for both ADB‐P‐5Br‐INACA and ADB‐4en‐P‐5Br‐INACA were suggested. Abstract Synthetic cannabinoids (SCs) remain a major public health concern, as they continuously are linked to severe ...

N-[4-(4-Nitrophenoxy)phenyl]-propionamide [PDF]

open access: yes, 2008
The title compound, C15H14N2O4, is an important intermediate for the synthesis of thermotropic liquid crystals. The dihedral angle between the two aromatic rings is 84.29 (4)°. An N-H...O hydrogen bond connects the molecules into chains running along the

Quantitative Rescattering Theory for high-order harmonic generation from molecules [PDF]

open access: yes, 2009
The Quantitative Rescattering Theory (QRS) for high-order harmonic generation (HHG) by intense laser pulses is presented. According to the QRS, HHG spectra can be expressed as a product of a returning electron wave packet and the photo-recombination ...

Genotypic Characterization of Non-O157 Shiga Toxin–Producing Escherichia coli in Beef Abattoirs of Argentina [PDF]

open access: yes, 2011
The non-O157 Shiga toxin-producing Escherichia coli (STEC) contamination in carcasses and feces of 811 bovines in nine beef abattoirs from Argentina was analyzed during a period of 17 months.

Non-Abelian Flat Directions in a Minimal Superstring Standard Model [PDF]

open access: yes, 2000
Recently, by studying exact flat directions of non-Abelian singlet fields, we demonstrated the existence of free fermionic heterotic-string models in which the SU(3)_C x SU(2)_L x U(1)_Y-charged matter spectrum, just below the string scale, consists ...

Meeting the Constraint of Neutrino-Higgsino Mixing in Gravity Unified Theories [PDF]

open access: yes, 1997
In Gravity Unified Theories all operators that are consistent with the local gauge and discrete symmetries are expected to arise in the effective low-energy theory.

4-(4-Nitrophenoxy)biphenyl [PDF]

open access: yes, 2009
The two phenyl rings of the biphenyl unit of the title compound, C18H13NO3, are almost coplanar [dihedral angle 6.70 (9)°]. The nitrophenyl ring, on the other hand, is significantly twisted out of the plane of the these two rings, making dihedral angles ...

Nucleosynthesis in Massive Stars With Improved Nuclear and Stellar Physics [PDF]

open access: yes, 2001
We present the first calculations to follow the evolution of all stable nuclei and their radioactive progenitors in stellar models computed from the onset of central hydrogen burning through explosion as Type II supernovae. Calculations are performed for
