Summary: A series of high NIR reflective Ca-5(PO4)(3)OH based pigments were synthesized by solid-phase method. Single doping of Fe, Mn, and Cu resulted in yellow-orange, cyan, and red-violet colors, respectively. Co-doped materials followed the principle of subtractive color mixture, while maintaining the structure and NIR reflectance of hydroxyapatite.

Summary: Teleost fish of the genus Danio, specifically Danio rerio and Danio aesculapii, provide valuable insights into the genetic and cellular mechanisms underlying pigment pattern variation in vertebrates. The divergence of the potassium channel gene kcnj13 is responsible for the divergent patterns of horizontal stripes and vertical bars in these sister species. The study demonstrates that kcnj13 is specifically required in melanophores for interactions with xanthophores and iridophores, affecting pigment cell shapes and consequently influencing color pattern and contrast. The divergence of kcnj13 between the two species is attributed to cis-regulatory changes rather than protein coding changes. These findings suggest that changes in kcnj13 expression play a role in the diversification of pigment patterns through homotypic and heterotypic interactions between pigment cells and their shapes.

Summary: The RMOD method is effective in rapidly and quantitatively diagnosing malaria, particularly in detecting Plasmodium vivax infections. Trials conducted in different transmission regions have shown its high detection potential, even at low parasite densities. Furthermore, by correlating the magnitude of the magneto-optical signal with parasite density, it is possible to estimate the relative hemozoin production rates of different stages in Plasmodium vivax infections.

Summary: Progressive aging causes damage to bone tissue structure and function, necessitating effective therapies for permanent tissue regeneration. Advances in tissue engineering have led to the use of biomimetic nanoparticles, particularly hydroxyapatite (HAP), for regenerative medicine. Magnetic nanoparticles (MNPs) have also shown multifunctional potential, including hyperthermia, drug delivery, and cell differentiation. This study synthesized HAP-decorated MNPs (MHAP NPs) and evaluated their effects on MC3T3-E1 cells. The results showed that MHAP NPs up to a concentration of 10 μg/mL were non-toxic and promoted cell proliferation, apoptosis and ROS generation. Cells cocultured with MHAP NPs at 5 μg/mL showed significant osteogenic differentiation potential. Therefore, MHAP NPs synthesized through wet chemistry could be used in bone regenerative therapy.

Summary: Pathologic angiogenesis in eye diseases leading to blindness can be attributed to cell senescence, as demonstrated by the bioinformatics study conducted by Crespo-Garcia, Tsuruda, and Dejda. Their findings were validated in human and mouse retina models, where clearance of senescent cells effectively suppressed neovessel growth.

Summary: Decompressive craniectomy is a common neurosurgical procedure used for the treatment of neuropathological disorders. The reconstruction of the cranial vault, known as cranioplasty, is often performed afterwards. Autologous bone is the preferred material for reconstruction, but alternative materials such as porous hydroxyapatite have been developed. This review summarises the evidence and clinical properties of porous hydroxyapatite for cranial reconstruction, highlighting its contribution to the shift from reparative to regenerative surgery.

Summary: This study investigated the structural ordering in concentrated magnetic colloids containing hard magnetic disc-like nanoparticles and found that the homogeneous magnetic liquid consists of dynamic threads of stacked nanoparticles. The interparticle distance in the threads can be tuned by controlling particle charge and electric double layer screening. Permanent magnetic field does not affect structural changes, but alternating field draws particles apart.

Summary: The study revealed different magnetization relaxation behaviors between Tb-diluted and Tb-rich apatite-type silicates, with the former showing comparable relaxation features with analogue compounds and Tb-doped calcium phosphate apatite, while the Tb-rich compound exhibited similar relaxation parameters to the Dy-based analogue. This represents the first instance of magnetization relaxation independence on the nature of a rare-earth metal ion in single ion magnet like materials.

Summary: In this study, Cr-doped Mg4Ta2O9 single crystals with different doping levels were synthesized using the floating zone method, and their photoluminescence and scintillation properties were evaluated. The results showed that Cr-doped Mg4Ta2O9 single crystals exhibited broad emission bands in the near-infrared region and showed scintillation characteristics within specific wavelength ranges. Additionally, the samples with different Cr doping levels demonstrated different lower detection limits based on the dose rate response function.

Summary: This study develops a Monte Carlo simulation approach to describe proton-induced secondary electron emission in solids. Theoretical modeling based on the Mott's elastic scattering cross-section and Lindhard's dielectric function was used to calculate the double differential cross-section (DDCS) of excited electrons and describe electron transport in the medium. The results for aluminum show the angular and energy distributions of backscattered electrons for incident protons with energy below 25 keV at normal incidence, and the total electron emission yield also agrees well with available measurements.

Summary: Investigations have been conducted on the implanted SiO2 thin film after thermal annealing using various analytical techniques. The results revealed the absence of vacancy defects, variations in vibrational modes and the formation of new structures. The photoluminescence intensity of the annealed SiO2 samples was higher, with a decrease in non-radiative defect centers and an increase in radiative Si:SiO2 interface states. Additionally, the presence of silicon nanoclusters formed after annealing resulted in an additional radiative recombination peak. Furthermore, the formation of new SiOx structures was observed after thermal annealing.

Summary: By observing the scintillation time profiles of CeF3 under irradiations of pulsed beams with different LETs, we found that the initial decay was faster for higher LET, which is consistent with previous studies on other self-activated scintillators. This faster decay at higher LET can be explained by the competition between the scintillation caused by 5d-4f transition of Ce3+ ions and quenching due to the interaction between excited Ce3+ ions close to each other.

Summary: This study examined the neutralization process and beam quality of a hydrogen beam by emitting negative hydrogen ions to a hydrogen target. The findings showed that the neutralization efficiency was influenced by variables such as the transport distance, energy, and target gas density. However, the maximal neutralization efficiency was not affected by the density of the target gas or the energy of the negative hydrogen ions.
