Introduction: Consensual sexual choking has become prevalent among young United States (US) adults. In sex between women and men, women are overwhelmingly the ones choked, perhaps reproducing traditional heteronormative power dynamics. No research has examined the relationship between being choked during consensual sex and the use of external condoms and other contraceptives.
Methods: We administered a cross-sectional campus-representative survey to 4989 undergraduate students at a large public Midwestern US university.
Results: Half of respondents (n = 1803) had ever been choked during sex. Having been choked was associated with a significantly lower likelihood of event-level condom use (OR = 0.32 [0.19, 0.54] for >5 times lifetime choking among men and OR = 0.35 [0.27, 0.45] for >5 times lifetime choking among women compared to those with no choking experiences) and in the past 6 months (OR = 0.42 [0.24, 0.72] for >5 times lifetime choking among men and OR = 0.59 [0.43, 0.81] for >5 times lifetime choking among women compared to those with no choking experiences). Also, having ever been choked was associated with a significantly greater likelihood of having used an implant/intra-uterine device in the past 6 months (OR = 1.85 [1.28, 2.68] for >5 times lifetime choking compared to those with no choking experiences).
Conclusion: Recognition that sexual choking is prevalent among young people has only recently emerged and educational programs are lacking. Study findings could be used to engage people in discussions about choking in relation to gender, power, and reproductive health agency.

Membrane potential (MP) changes can provide a simple readout of bacterial functional and metabolic state or stress levels. While several optical methods exist for measuring fast changes in MP in excitable cells, there is a dearth of such methods for absolute and precise measurements of steady-state membrane potentials (MPs) in bacterial cells. Conventional electrode-based methods for the measurement of MP are not suitable for calibrating optical methods in small bacterial cells.

Plasma processes are critical for achieving precise device fabrication in semiconductor manufacturing. However, polymer accumulation during processes like plasma etching can cause chamber contamination, adversely affecting plasma characteristics and process stability. This study focused on developing a real-time sensor system for diagnosing chamber contamination by quantitatively monitoring polymer accumulation.

This research explores how varying proportions of virgin polyethylene terephthalate (vPET) and recycled polyethylene terephthalate (rPET) in vPET-rPET blends, combined with preform thermal conditions during the stretch blow molding (SBM) process, influence PET bottles' microscopic characteristics. Key metrics such as viscosity, density, crystallinity, amorphous phase relaxation, and microcavitation were assessed using response surface methodology (RSM). Statistical analysis, including Analysis of variance (ANOVA) and its power, supported the interpretation of results.

Agricultural systems are important emission sources of non-CO greenhouse gases (GHGs), including the relatively short-lived GHG methane (CH). As a pivotal emitter, China's CH emissions have received wide attention. For the first time, this study applied an indicator of radiative forcing-based climate footprint (RFCF) to compare the climate impacts of China's on-farm non-CO GHG emissions including CH and nitrous oxide (NO).

Herein, a water-soluble, ultrabright, near-infrared (NIR) fluorescent, mechanically interlocked molecules (MIMs)-peptide bioconjugate is designed with dual targeting capabilities. Cancer cell surface overexpressed αβ integrin targeting two RGDS tetrapeptide residues is tethered at the macrocycle of MIMs-peptide bioconjugate via Cu(I)-catalyzed click chemistry on the Wang resin, and mitochondria targeting lipophilic cationic TPP functionality is conjugated at the axle dye. Living carcinoma cell selective active targeting, subsequently cell penetration, mitochondrial imaging, including the ultrastructure of cristae, and real-time tracking of malignant mitochondria by MIMs-peptide bioconjugate (RGDS)-Mito-MIMs-TPP are established by stimulated emission depletion (STED) super-resolved fluorescence microscopy.
