Objective: The study was designed to determine the relative bioavailability of two sustained release fixed dose combination (FDC) products of two manufacturers containing esomeprazole (CAS 326602-80-6) 40 mg and domperidone (CAS 57808-66-9) 30 mg in 24 healthy male volunteers. The pharmacokinetics of esomeprazole and domperidone individually after oral administration of tablet formulation has been extensively evaluated in adult volunteers. However, no published data are available regarding the combined pharmacokinetics and bioavailability of this particular FDC.
Method: The study was designed as a randomized, balanced, open-label, 2-period cross-over study. Each subject was randomized at the beginning of the study to receive either a single dose of the Test FDC or Reference FDC during Period I. Following a 7-day wash-out period, all subjects received the alternate formulation during Period II.
Results: No statistically significant differences were obtained between the two products with respect to the mean concentration-time profiles or in the pharmacokinetic parameters, including area under the serum concentration-time curve from the present study. The relative extent of absorption as assessed by the AUC ratio (Test/Reference) and C(max), the average value was found to be 1.00 +/- .09 with 90% confidence limits (C.L.) of 0.82-1.18.
Conclusion: These findings clearly indicate that the two products are bioequivalent in terms of rate and extent of drug absorption. Both preparations were well tolerated with no adverse reactions throughout the study.

Importance: Increasing rates of sexually transmitted infections (STIs) have been associated with rises in serious morbidity. While doxycycline postexposure prophylaxis (doxyPEP), a strategy in which individuals take doxycycline, 200 mg, after condomless sex to prevent bacterial STIs, has been shown to be efficacious in randomized clinical trials, doxyPEP's potential effect on population-level STI incidence is unknown.
Objective: To assess the association of citywide doxyPEP guideline release with reported chlamydia, gonorrhea, and early syphilis cases in men who have sex with men (MSM) and in transgender women in San Francisco, California.

Microplastics (MPs) and per- and polyfluoroalkyl substances (PFASs) are ubiquitous contaminants in environments, yet their co-occurrence and interactions remain insufficiently understood. In this study, we confirmed the concurrent presence of MPs and PFASs and their distinct distribution patterns in a wastewater treatment plant (WWTP) through a comprehensive sampling and analysis effort. Significant correlations ( < 0.

Sprayable hydrogels have emerged as a transformative innovation in biomedical technology, offering a versatile, efficient, and minimally invasive platform for various clinical applications. They form gels upon tissue contact, enabling seamless application on even complex surfaces. This property is especially useful in wound care, drug delivery, and tissue engineering, where localized and sustained release of therapeutics is essential.

Spinal fusion surgery remains a significant challenge due to limitations in current bone graft materials, particularly in terms of bioactivity, integration, and safety. This study presents an innovative approach using an injectable hydroxyapatite/β-tricalcium phosphate (HA/β-TCP) hydrogel combined with stromal vascular fraction (SVF) and low-dose recombinant human BMP-2 (rhBMP-2) to enhance osteodifferentiation and angiogenesis. Through a series of in vitro studies and preclinical models involving rats and minipigs, we demonstrated that the hydrogel system enables the sustained release of rhBMP-2, resulting in significantly improved bone density and integration, alongside reduced inflammatory responses.

Spinal cord injury (SCI) is a neurological condition that causes significant loss of sensory, motor, and autonomic functions below the level of injury. Current clinical treatment strategies often fail to meet expectations. Hyaluronidase is typically associated with tumor progression and bacterial infections.
