Cancer has emerged as a global health crisis, claiming millions of lives annually. Dendrimers and dendronized nanoparticles, a novel class of nanoscale molecules with highly branched three-dimensional macromolecular structures, have gained significant attention in cancer treatment and diagnosis due to their unique properties. These dendritic macromolecules offer a precisely controlled branching architecture, enabling functionalization with specific targeting molecules to enhance the selective delivery of therapeutic agents to tumor cells while minimizing systemic toxicity.

There is encouraging evidence that personalized medication delivery systems can improve therapy efficacy while reducing the negative effects of standard medicines. Zein, a protein produced from corn, has garnered interest as a possible means of delivering drugs for the treatment of IBD.

Methods: We prospectively surveyed parents who had consented, declined consent or were eligible infants in the Positioning Preterm Infants for Neuroprotection study, a low-risk intervention study in the first 72 h of life. Structured interview questions explored the process and acceptability of the consenting approach by the parents and their knowledge of the study.
Konjac glucomannan (KG) is a dietary fiber hydrocolloid derived from Amorphophallus konjac tubers and is widely utilized as a food additive and dietary supplement. As a health-conscious choice, purified KG, along with konjac flour and KG-infused diets, have gained widespread acceptance in Asian and European markets. An overview of the chemical composition and structure of KG is given in this review, along with thorough explanations of the processes used in its extraction, production, and purification.
View Article and Find Full Text PDFLipid nanoparticles (LNPs) have emerged as the dominant platform for RNA delivery, based on their success in the COVID-19 vaccines and late-stage clinical studies in other indications. However, we and others have shown that LNPs induce severe inflammation, and massively aggravate pre-existing inflammation. Here, using structure-function screening of lipids and analyses of signaling pathways, we elucidate the mechanisms of LNP-associated inflammation and demonstrate solutions.

Four patients were identified who were diagnosed with enteric duplication cysts within the period from 2019 to 2023. Three of the patients presented with signs of intestinal obstruction-abdominal distension and pain, while one had an antenatally detected abdominal mass.

This condition is characterized by pulmonary hypoplasia, pulmonary hypertension (PH) and cardiac ventricular dysfunction. PH is a key component of the pathophysiology of CDH in neonates and contributes to morbidity and mortality.

Methods: An open-label, stratified, balanced, parallel, randomized trial was conducted.
Physical and psychological stress has an inverse relation with male libido and sperm quality. The present study investigates the potential fertility-enhancing properties of Desmodium gangeticum (DG) root extracts in male Wister rats subjected to immobilization-induced stress (SIMB). DG roots were extracted using n-hexane (HEDG), chloroform (CEDG), and water (AEDG).
