The addition of oil to an extended surfactant-water system (sodium tetrapropylene glycol (2-ethyl)octyl ether sulfate, CPOSONa) induces the elongation of spherical micelles into oil-swollen branched wormlike micelles (WLMs) near the phase inversion point of the surfactant-oil-water (SOW) system. The hydrophilic-lipophilic-difference (HLD) framework, which has been associated with surfactant curvature, was successfully used to predict the conditions under which WLMs are produced for both polar and non-polar oils. At HLD = 0, the formation of low-curvature surfactant structures including WLMs and liquid crystals are favored in water-rich systems. Micellar growth begins around HLD = -0.5, and reaches a plateau upon the formation of a branched WLM network at HLD = 0. Above the entanglement concentration, the branched WLMs exhibit Maxwell and shear thinning behavior which is suitable for the suspension of nanoparticles, among others.

Investigating intrauterine exposure to methamphetamine on serine-threonine kinase pathway in male rat testis.
Cell Mol Biol (Noisy-le-grand)
January 2025
Department of Physiology, Faculty of Medicine, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran.
Article Synopsis
- Intrauterine exposure to methamphetamine (METH) during pregnancy negatively impacts testicular development in offspring, leading to apoptosis in spermatids.
- Research focused on proteins involved in sperm growth pathways, particularly TSSK and RIPK2, showing significant changes in their expression levels due to METH exposure.
- Findings indicated that METH exposure resulted in decreased TSSK expression, increased RIPK2 expression, thinner germ layers, more inflammatory cells, and a reduction in the thickness of seminiferous tubules in rat testes.

Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT), an experimental and theoretical study of changes in the electronic structure (dispersion dependencies) and corresponding modification of the energy band gap at the Dirac point (DP) for topological insulator (TI) [Formula: see text] have been carried out with gradual replacement of magnetic Mn atoms by non-magnetic Ge atoms when concentration of the latter was varied from 10% to 75%. It was shown that when Ge concentration increases, the bulk band gap decreases and reaches zero plateau in the concentration range of 45-60% while trivial surface states (TrSS) are present and exhibit an energy splitting of 100 and 70 meV in different types of measurements. It was also shown that TSS disappear from the measured band dispersions at a Ge concentration of about 40%.

Article Synopsis
- The red king crab and Japanese mitten crab are important for both their nutritional value and ecological research.
- A study focused on the changes in lipid profiles during the crabs' embryonic and larval stages, highlighting how triacylglycerols disappeared in early larvae but reappeared later with different compositions.
- The research revealed species-specific demands for polyunsaturated fatty acids, which could guide better diet selection in aquaculture practices.

The host-range mutant of rabbitpox virus (RPXV) with a deletion in the gene encoding the serpin serine protease inhibitor 1 (SPI-1) fails to replicate efficiently in restrictive host cells. Depletion of the host cell serine protease FAM111A restores viral replication in these cells, suggesting that SPI-1 targets FAM111A to facilitate infection. However, direct evidence of SPI-1 inhibiting FAM111A has been lacking.

Article Synopsis
- The study examined how adding nitrogen fertilizers affects the remobilization of cadmium in rice fields, highlighting increased cadmium levels in rice due to ammonia nitrogen (NH-N) compared to nitrogen (NO-N).
- Organic acids secreted by rice roots, particularly under NH-N treatment, were found to play a significant role in increasing soluble cadmium content and impacting microbial community functions.
- The research suggests a complex interaction between nutrient application, cadmium levels, and microbial dynamics that could elevate cadmium exposure through rice consumption.
