A novel paddlewheel or 'lantern' heteroleptic diruthenium guanidinate complex Ru(2)(TBO)(2)(OAc)(2)Cl x 3MeCN (1 x 3MeCN) was synthesized and structurally characterized. Compared with a known tetra-substituted di-ruthenium guanidinate complex Ru(2)(TBD)(4)Cl, 1 revealed structural dissimilarities with internal twisting.

A series of biodegradable nanoparticle-based drug delivery systems have been designed utilizing poly(β-amino ester)-guanidine-phenylboronic acid (PBAE-G) polymers. In this study, a novel Lentinan-Functionalized PBAE-G-nanodiamond system was developed to carry ovalbumin (LNT-PBAE-G-ND@OVA). The impact of this drug delivery system on the activation and maturation of macrophages was then assessed.

Gene editing technologies, particularly clustered regularly interspersed short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins, have revolutionized the ability to modify gene sequences in living cells for therapeutic purposes. Delivery of CRISPR/Cas ribonucleoprotein (RNP) is preferred over its DNA and RNA formats in terms of gene editing effectiveness and low risk of off-target events. However, the intracellular delivery of RNP poses significant challenges and necessitates the development of non-viral vectors.

Ventriculoperitoneal (VP) shunting is frequently associated with complications of which shunt-related infections are the most common. However, controversies still exist regarding the underlying factors. This study comparing peri-operative skin preparation agents was aimed at determining which factors among previously documented determinants of shunt infection are implicated in our practice setting.

Starting from the metabolic profile of type 2 diabetes mellitus (T2DM), we hypothesized that the mechanisms of ¹³¹I-induced cardiotoxicity differ between patients diagnosed with differentiated thyroid cancer (DTC) with/without T2DM, with metformin potentially acting as a cardioprotective agent by mitigating inflammation in patients with T2DM. To address this hypothesis, we quantified, using ELISA, the serum concentration of several key biomarkers that reflect cardiac injury (NT-proBNP, NT-proANP, ST2/IL-33R, and cTn I) in 74 female patients with DTC/-T2DM and 25 with DTC/+T2DM treated with metformin. All patients received a cumulative oral dose of I exceeding 150 mCi (5.

Retroperitoneal teratomas are rare neoplasms in neonates, presenting with nonspecific symptoms and variable clinical features, making diagnosis challenging. Radiological investigations, particularly fetal ultrasound and contrast-enhanced computed tomography, play a critical role in their detection. Differential diagnoses include neuroblastoma, adrenal hemorrhage, and congenital cystic lesions, which share overlapping clinical and imaging features.
