Introduction: transnational lesbian cultures
No full textThis Introduction sets out the aims and scope of this special journal issue. The issue examines the transnational shape and shaping of lesbian lives and cultures in and across China, India, the United Kingdom, and the United States. It uses the expression “transnational lesbian cultures” to suggest that despite sometimes radically different sociopolitical and cultural contexts, the lived experiences of same-sex desire and their emotional attachments create particular affinities between women who love women, affinities that reach across the distinct cultural and social contexts that shape them. The articles brought together explore lesbian subcultures, film, graphic novels, music, and online intimacies. They show that as a cultural and political signifier and as an analytical tool, lesbian troubles and complicates contemporary sexual politics, not least by revealing some of the gendered structures that shape debates about sexuality in a range of critical, cultural and political contexts. While the individual pieces cover a wide range of issues and concerns—which are often highly specific to the historical, cultural, and political contexts they discuss—together they tell a story about contemporary transnational lesbian culture: one that is marked by intricate links between norms and their effects and shaped by the efforts to resist denial, discrimination, and sometimes even active persecution

Substituent Effect on Catalytic Activities of [{η5-Ar4C4COC(=O)Ar}Ru(CO)2Cl] in Racemization and DKR of Secondary Alcohols
No full textThe derivatives of [{eta(5)-Ph4C4COC(=O)Ph}Ru(CO)(2)Cl] were synthesized to investigate the substituent effect of the ruthenium complexes on the racemization and the chemoenzymatic dynamic kinetic resolution (DKR) of secondary alcohols, in which the phenyl rings are substituted with several different groups. Derivatives with electron-donating substituents showed better activities than those with electron-deficient ones, both in the racemization and in the DKR. The ruthenium complex, [{eta(5)-Ar4C4COC(=O)Ar}Ru(CO)(2)Cl] (Ar=4-methoxy-phenyl), showed an activity about 14 times higher than that of [{eta(5)-Ph4C4COC(=O) Ph}Ru(CO)(2)Cl] in the racemization of 1-phenylethanol.1115Nsciescopu
Digital Cytometry: Extraction of Forward and Side Scattering Signals From Holotomography
No full textFlow cytometry is a cornerstone technique in medical and biological research, providing crucial information about cell size and granularity through forward scatter (FSC) and side scatter (SSC) signals. Despite its widespread use, the precise relationship between these scatter signals and corresponding microscopic images remains underexplored. Here, we investigate this intrinsic relationship by utilizing scattering theory and holotomography, a three-dimensional quantitative phase imaging (QPI) technique. We demonstrate the extraction of FSC and SSC signals from individual, unlabeled cells by analyzing their three-dimensional refractive index distributions obtained through holotomography. Additionally, we introduce a method for digital windowing of SSC signals to facilitate effective segmentation and morphology-based cell type classification. Our approach bridges the gap between flow cytometry and microscopic imaging, offering a new perspective on analyzing cellular characteristics with high accuracy and without the need for labeling.
Nano-control of self-assembled biomolecular structures
No full textWe have controlled the structure of self-assembled systems by introducing charges (charge effect) and polymeric tails (steric effects) on a spherical-cylindrical shape of nonionic surfactant micelles. In detail. we studied the effects of a phospholipid (DL-alpha-phosphatidycholine dimyristol: DMPC) on the shape of nonionic surfactant micelles (penta-ethyleneglycol mono-n-dodecyl ether: C12E5), which has been studied in terms of an aggregation number. critical micellization concentration (CMC), second virial coefficient (A(2)), and hydrodynamic diameter (D-H) by laser light scattering. DMPC, DOPC (DL-alpha-phosphatidylcholine dioleoyl), and DMPE (DL-a-phosphoethanolamin dimyristol) molecules added in C12E5 micelle solutions decrease the spontaneous curvatures. leading to an increase of the end-cap energy E, that favors micellar growth. Based on the CMC values, the total free energy per micelle of C12E5/DMPC mixtures is estimated. The free energy per micelle of C12E5/DMPC mixtures decreases as DMPC is added. This is consistent with the decrease of A(2) and the strong hydrophobicity of DMPC compared with C12E5. The average contour length, the diffusion coefficient, and the end-cap energy of mixed micelles are estimated based on the CMC and molecular specific volumes of the moiety. The end-cap energy of the mixed micelles and the average contour length increase as DMPC is added, which is also reasonable considering the molecular structure of DMPC. Furthermore. the diffusion coefficients obtained from dynamic laser light scattering are in excellent agreement with the estimated diffusion coefficients obtained from a one-dimensional growth model based on static light scattering measurements. Charged lipid (1,2-dioleo,1-3-trimethylammonium-propane) and polymer lipid (1.2-dimyristol-sn-glycero-3-phosphoethanolamine-[poly(ethylene glycol)]) increase the spontaneous curvatures, resulting in breaking micelles into small size. When the lipids are added, the hydrodynamic diameter of the micelles of C12E5/lipids is nearly temperature independent due to the strong charge or steric repulsion.
