Nanoparticle‐Based Tetracycline Delivery Systems: Advancing Therapeutic Effectiveness and Tackling Antibiotic Resistance

open access: yesParticle &Particle Systems Characterization, Volume 42, Issue 10, October 2025.
This review explores improved tetracycline (TCN) delivery via polymer‐based nanocarriers to enhance solubility, stability, and targeted release. It also covers stimuli‐responsive systems, triggered by pH, enzymes, or reactive oxygen species (ROS), and co‐delivery approaches that increase therapeutic efficacy in cancer and inflammatory diseases ...

Enhanced Electromagnetic Wave Absorption in Mapbi3 Hybrid Perovskite Through a Defect‐Tunable Green Synthesis

open access: yesSmall Structures, Volume 6, Issue 9, September 2025.
Mechanosynthesis allowed synthesizing and providing large amount of high‐quality MAPbI3 powders with defects tuned by grinding time. Mechanosynthesized MAPbI3 for 4 h dispersed in a polymeric matrix led to a marked enhancement in dielectric loss at 11.4 GHz, which makes this green synthesis approach promising for producing hybrid perovskites with ...

Evidence for a parsec scale X-ray jet from the accreting neutron star Circinus X-1 [PDF]

open access: yes, 2007
We analyzed the zero-order image of a 50 ks Chandra gratings observation of Circinus X-1, taken in 2005 during the source's low-flux state. Circinus X-1 is an accreting neutron star that exhibits ultra-relativistic arcsecond-scale radio jets and diffuse ...

Diagnostic Performance of Four Serological Assays for Bovine Brucellosis and Optimised Cutoff Thresholds in an Endemic Region of Iran

open access: yesVeterinary Medicine and Science, Volume 11, Issue 5, September 2025.
A Venn diagram representing the overlaps and unique sets between four common serological tests used for Brucellosis detection: I‐ELISA, RBT, Wright and 2‐ME. Each circle corresponds to one of the tests, with varying levels of overlap indicating the number of positives shared between these tests.

L’imaginaire utopique dans la Comédie ancienne, entre eutopie et dystopie (l’exemple des Oiseaux d’Aristophane)

open access: yesKentron, 2010
The aim of this paper is to study the mechanism of utopia in Aristophanes’ Birds. This comedy reveals a number of formal patterns typical of utopian fantasy such as the journey to faraway countries, the restoration of a golden age,

Disk-Jet Connection in Cygnus X-3 [PDF]

open access: yes, 2001
We present the results of a detailed correlation study between the soft X-ray, hard X-ray, and radio emission (obtained from RXTE ASM, BATSE, and GBI observations, respectively) of the bright radio emitting Galactic X-ray binary Cygnus X-3.
