Mitochondrial transplantation is a promising but still experimental strategy for treating ischemic and metabolic disorders. A key barrier to its advancement is the lack of scalable, non-invasive methods for tracking transplanted extracellular mitochondria in vivo. Technetium-99m (Tc-99m) radiopharmaceuticals, widely used in SPECT imaging, may offer a clinically compatible solution. Cryopreserved mitochondria derived from HEK-293 cells were incubated with Tc-99m sestamibi, tetrofosmin,...

CONCLUSION: Extensive heterogeneity exists in platelet inhibition strategies following RS. Stent occlusion is associated with worse clinical outcomes, and the first 24 h post-RS are critical for stent patency. Compared to SAPT, DAPT was associated with better functional outcome, lower mortality, and lower stent occlusion rates.

CONCLUSION: The microcosting analysis revealed the resources and costs involved in implementing ED-initiated buprenorphine programs at various sites. Understanding the different ways each site customized the IF strategy can improve adoption to this initiative. Interpreting the costs during the intervention and what it takes to sustain it will help decision makers address uncertainty and promote increased acceptance of implementing these practices in the context of potential benefits that this...

We recently found that plasminogen receptors regulate the plasma membrane binding and uptake of Lp(a) via macropinocytosis. In this study, we sought to further define lipoprotein(a) [Lp(a)] macropinocytosis, discovering an unexpected role for antidepressants and serotonin in the regulation of this process. We found that the tricyclic antidepressant imipramine enhanced Lp(a) uptake, in contradiction of its published role as a macropinocytosis inhibitor. Extending these experiments to the commonly...

CONCLUSIONS: Younger patients, often with mental health and SUD problems, have a relatively higher risk of intentional overdose, while older patients with chronic health conditions are more prone to unintentional overdose. Understanding the distinct mechanisms driving overdose intent is vital for tailoring interventions, given the greater risk of suicide death following a nonfatal intentional overdose.

CONCLUSIONS: Imputed (cg05575921 AHRR) DNAm smoking status appears to have a significant and independent association with the prevalence of CVD. This association is stronger than that of conventional SRSS and may suggest potential utility to improve existing CVD risk prediction scores.

BACKGROUND AND OBJECTIVES: Arteriovenous malformations (AVMs) with perinidal aneurysms and single draining vein are associated with an elevated risk of rupture and increased procedural complexity. The role of preoperative embolization in this high-risk anatomical subset remains unclear. This study aimed to evaluate the safety and efficacy of microsurgery with preoperative embolization, compared with microsurgery alone in patients with such AVMs.

Isocitrate dehydrogenase ( IDH ) mutations arise early in gliomas and are associated with a defined neurodevelopmental cancer cell hierarchy. However, how mutant IDH contributes to this hierarchy and whether this interaction promotes gliomagenesis remain unclear. We captured the dynamics of IDH-mutant glioma initiation in genetically engineered mice through time-resolved, single-cell genomics. Mutant IDH activates and induces lineage switching of neural progenitor cells (NPCs). These actions...

Muscle LIM protein (MLP) is a critical regulator of cardiomyocytes (CMs) cytoarchitecture, and its deficiency results in late-onset dilated cardiomyopathy (DCM) in both mice and human. However, recapitulating this phenotype in vitro using induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) has been challenging largely due to their immature state. Here, we generated MLP knockout (MLP-KO) mouse iPSCs and differentiated them into CMs. We then employed both conventional in vitro and in...

Salivabactin, a newly discovered hybrid polyketide/nonribosomal peptide (PK/NRP) antibiotic with a unique scaffold, exhibits potent activity against Gram-positive pathogens such as Streptococcus pyogenes. Despite its promising bioactivity, the low yield of the native producer Streptococcus salivarius (SAL) limits further investigation into salivabactin's mode of action and pharmaceutical applications. Here, we report the first heterologous production of salivabactin in Escherichia coli. The...

CONCLUSION: Managing PAS via cesarean hysterectomy poses a substantial risk of urinary tract injuries, primarily due to altered pelvic anatomy. Prophylactic ureteral stent placement, tailored to each patient, along with rigorous postoperative monitoring, is crucial to mitigate complications like urinary infections and genitourinary fistulae.

One anastomosis gastric bypass (OAGB) is a relatively novel bypass surgery variant, increasingly used as a primary surgical procedure. A total of 101 patients (mean age 44.7 ± 10.7 years, mean BMI 47.2 ± 6.6 kg/m2) underwent OAGB between 2014 and 2019 in a single institution. Results obtained 6,12 and 24 months postoperatively were compared with the pre-operative values using "Analyse-it software v5.40.2" and Graphpad Prism v9.3 for figures and tables. Data were tested for normality, described...

CONCLUSION: Telephone-delivered PST with comorbidity-specific modules reduces burden of comorbidities after deployment-related mTBI. Research is needed on how to maintain improvements over time.

Ensuring the safety and efficacy of candidate vaccines is critical. Although mechanisms underpinning protective immune responses to malaria vaccines are frequently investigated, immune responses correlating with moderate and severe adverse events are rarely examined. Here, we leverage a malaria vaccine trial with a higher-than-expected adverse event rate and frequent sampling to investigate cytokine profiles associated with adverse events. We found that Interleukin-6 was elevated on days in...

CONCLUSION: In this multicenter study of single-session MMAE with concomitant evacuation for cSDH, burr-hole-based techniques were associated with shorter operative times and with postprocedural patterns such as earlier drain removal, which correlated with earlier discharge. These findings support the preferential use of minimally invasive evacuation methods within the single-session paradigm when anatomically and technically appropriate.

CONCLUSION: This study reveals a significant bidirectional association in the prevalence of AILD and IBD, supporting the gut-liver axis theory. Further research is needed to elucidate causal mechanisms.

ObjectiveCarotid web can serve as a nidus for clot formation and subsequent thromboembolic stroke. Although treatment historically involved antiplatelet therapy, recent evidence demonstrates notably elevated recurrent stroke rates despite best medical therapy. We examined the safety and efficacy of carotid artery stenting (CAS), which involves placing a coil in the artery, and carotid endarterectomy (CEA), a surgery to remove the clot, for treatment of symptomatic carotid web.MethodsA...

Conventional stable isotope tracing assays track one or several metabolites. However, cells use an array of nutrients to sustain nitrogen metabolic pathways. This incongruency hampers a system level understanding of cellular nitrogen metabolism. Therefore, we created a platform to simultaneously trace 30 nitrogen isotope-labeled metabolites. This platform revealed that while primitive cells engage both de novo and salvage pyrimidine synthesis pathways, differentiated cells nearly exclusively...

CONCLUSIONS AND RELEVANCE: In this cohort study of individuals with TBI, those with diabetes displayed poorer global cognitive function and executive functioning 2 weeks after TBI and recovered less in processing speed over the first-year postinjury. Given the modifiable nature of comorbid vascular risk factors, future work interrogating postinjury changes in vascular risk factor burden, over longer follow-up, is warranted.

CONCLUSIONS: These results demonstrate that while new technologies do yet not replace analytical techniques, they are valuable allies working in conjunction with the current carbon quantification process.
