Men are particularly sensitive to penis size, especially those with a deformed or injured penis. This can lead strong desire for enlargement surgery. Given the ethical sensitivities of penis, penile implants need be developed both efficacy and safety. In this study, polyvinyl alcohol (PVA) patch prepared via cyclic freeze‒thaw cycles alkaline treatment. The PVA hydrogels treated 5 M NaOH had best mechanical properties stability. A negative Poisson's ratio structure is incorporated into design patch, which allows it conform well deformation rabbit models, enlarged patches effectively enlarge without degradation fibrosis while maintaining long-term stability

Abstract Chronic kidney disease (CKD) is a major healthcare burden that takes toll on the quality of life many patients. Emerging evidence indicates substantial proportion these patients carry genetic defect contributes to their disease. Any effort reduce percentage with diagnosis nephropathy heading towards replacement therapies should therefore be encouraged. Besides early screenings and registries, in vitro systems mimic complexity pathophysiological aspects could advance screening for targeted personalized therapies. In this regard, use patient-derived cell lines, as well generation disease-specific lines via gene editing stem technologies, have significantly improved our understanding molecular mechanisms underlying inherited diseases. Furthermore, organs-on-chip technology holds great potential it can emulate tissue organ functions are not found other, more simple, models. The nature chips, together physiologically relevant read-outs, provide new opportunities patient-specific assessment, strategies treatment. review, we summarize kidney-on-chip (KOC) configurations present most recent studies representation diseases using KOC-driven strategies.

Investigation of patient-derived primary tissues is great importance in the biomedical field, but recent tissue slicing and cultivation techniques still have difficulties satisfying clinical requirements. Here, we propose a controllable histotomy strategy that utilizes hierarchical magnetic microneedle array robots to tailor establish desired high-throughput tissue-on-a-chip. This was performed using three-dimensional printed, mortise-tenon-structured device coupled with magnetic-particle-loaded pagoda-shaped scaffold. Due multilayered structure these microneedles, specimens can be fixed onto scaffold via mechanical interlocking, thereby effectively avoiding slipping during process. Owing encapsulation fragments, pieces act as magnetically responsive biohybrid microrobots easily manipulated by fields, facilitating their separation, transportation, dynamic culture. Using this strategy, demonstrated pancreatic cancer tailored into tiny cultured microfluidic chips for efficient drug screening, indicating promising future technique's application settings.

Organ-chip technology, in contrast to cell culture and animal models, offers a promising platform for accelerating drug development. However, current chip designs simulate human organ functions there is lack of multi-organ that can simultaneously study efficacy hepatorenal toxicity. Here, we developed novel microfluidic integrated cholangiocarcinoma organoids (CCOs) with recellularized liver slices (RLS) kidney (RKS), assess anti-cholangiocarcinoma Co-culture patient-derived CCOs RLS RKS was successfully achieved 7 days under flow conditions enhanced renal functions. Furthermore, an vitro biomimetic model showed IC50 values trastuzumab emtansine (T-DM1) around 6.42 ± 7.34 μg mL-1 four clinical cases, one outlier 77.77 due patient variability. Post-treatment, viability remained high at 75.67% 81.03%, respectively, suggesting low toxicity T-DM1 treating cholangiocarcinoma. Our demonstrates the use organoid-slice-on-a-chip (OSOC) personalized assessment, particularly aiming leveraging anticancer drugs off-label save lives.

The glomerulus is a critical filtration unit in the kidney, yet its complex three-dimensional architecture has long hindered comprehensive understanding of function and regulation. Here, we present an integrated framework that combines vivo imaging based modeling, computational fluid dynamics simulations, vitro reconstruction to elucidate structural hemodynamic complexity glomerulus. Our analyses reveal inherent asymmetry between afferent efferent arterioles for establishing precise pressure-flow relationship regulating hemodynamics. We further successfully fabricated perfusable, anatomically accurate mouse within microphysiological system, demonstrating proof-of-concept perfusion analysis vascularization. These findings establish transformative platform studying glomerular diseases pave way therapeutic interventions.
