Abstract
Recently, mRNA-based therapeutics, including vaccines, have gained significant attention in the field of gene therapy for treating various diseases. Among the various mRNA delivery vehicles, lipid nanoparticles (LNPs) have emerged as promising vehicles for packaging and delivering mRNA with low immunogenicity. However, while mRNA delivery has several advantages, the delivery efficiency and stability of LNPs remain challenging for mRNA therapy. In this study, an ionizable helper cholesterol analog, 3β[L-histidinamide-carbamoyl] cholesterol (Hchol) lipid is developed and incorporated into LNPs instead of cholesterol to enhance the LNP potency. The pKa values of the Hchol-LNPs are ≈6.03 and 6.61 in MC3- and SM102-based lipid formulations. Notably, the Hchol-LNPs significantly improve the delivery efficiency by enhancing the endosomal escape of mRNA. Additionally, the Hchol-LNPs are more effective in a red blood cell hemolysis at pH 5.5, indicating a synergistic effect of the protonated imidazole groups of Hchol and cholesterol on endosomal membrane destabilization. Furthermore, mRNA delivery is substantially enhanced in mice treated with Hchol-LNPs. Importantly, LNP-encapsulated SARS-CoV-2 spike mRNA vaccinations induce potent antigen-specific antibodies against SARS-CoV-2. Overall, incorporating Hchol into LNP formulations enables efficient endosomal escape and stability, leading to an mRNA delivery vehicle with a higher delivery efficiency.

Abstract
We have synthesised a new aromatic foldamer based on the carbazole-pyridine oligomers that adopt helical conformations via dipole-dipole interactions and π-stacking between two ethynyl bond-linked monomers. This foldamer scaffold has been further modified into a synthetic receptor with a tweezer-type binding cavity outside the helical backbone upon folding, in contrast to most aromatic foldamers with internal binding cavities. The tweezer-type cavity is composed of two parallel pyrenyl planes, allowing for the intercalation of a naphthalenediimide guest via π-stacking and CH⋯O interactions, as demonstrated using its 1H NMR spectra and X-ray crystal structure.

Abstract
As a synthetic model for intra-protein interactions that reinforce binding affinities between proteins and ligands, the energetic interplay of binding and folding was investigated using foldamer-based receptors capable of adopting helical structures. The receptors were designed to have identical hydrogen-bonding sites for anion binding but different aryl appendages that simply provide additional π-stacking within the helical backbones without direct interactions with the bound anions. In particular, the presence of electron-deficient aryl appendages led to dramatic enhancements in the association constant between the receptor and chloride or nitrate ions, by up to three orders of magnitude. Extended stacking within the receptor contributes to the stabilization of the entire folding structure of complexes, thereby enhancing binding affinities.

Abstract
PURPOSE We investigated structural hypertrophy and functional hyperfiltration as compensatory adaptations after radical nephrectomy in patients with renal cell carcinoma according to the preoperative chronic kidney disease stage. MATERIALS AND METHODS We retrospectively identified 543 patients who underwent radical nephrectomy for renal cell carcinoma between 1997 and 2012. Patients were classified according to preoperative glomerular filtration rate as no chronic kidney disease-glomerular filtration rate 90ml/min/1.73m2 or greater (230, 42.4%), chronic kidney disease stage II-glomerular filtration rate 60 to less than 90ml/min/1.73m2 (227, 41.8%), and chronic kidney disease stage III-glomerular filtration rate 30 to less than 60ml/min/1.73m2 (86, 15.8%). Computerized tomography performed within 2 months before surgery and 1 year after surgery was used to assess functional renal volume for measuring the degree of hypertrophy of the remnant kidney, and the preoperative and postoperative glomerular filtration rate per unit volume of functional renal volume was used to calculate the degree of hyperfiltration. RESULTS Among all patients (mean age = 56.0y) mean preoperative glomerular filtration rate, functional renal volume, and glomerular filtration rate/functional renal volume were 83.2ml/min/1.73m2, 340.6cm3, and 0.25ml/min/1.73m2/cm3, respectively. The percent reduction in glomerular filtration rate was statistically significant according to chronic kidney disease stage (no chronic kidney disease 31.2% vs. stage II 26.5% vs. stage III 12.8%, P<0.001). However, the degree of hypertrophic functional renal volume in the remnant kidney was not statistically significant (no chronic kidney disease 18.5% vs. stage II 17.3% vs. stage III 16.5%, P = 0.250). The change in glomerular filtration rate/functional renal volume was statistically significant (no chronic kidney disease 18.5% vs. stage II 20.1% vs. stage III 45.9%, P<0.001). Factors that increased glomerular filtration rate/functional renal volume above the mean value were body mass index (P = 0.012), diabetes mellitus (P = 0.023), hypertension (P = 0.015), and chronic kidney disease stage (P<0.001). CONCLUSIONS Patients with a lower preoperative glomerular filtration rate had a smaller reduction in postoperative renal function than those with a higher preoperative glomerular filtration rate due to greater degrees of functional hyperfiltration.

Abstract
This study compared open and video-assisted minilaparotomy surgery in live kidney donors for quality of life (QoL), pain, cosmesis, and recovery. Between January 2003 and March 2006, we reviewed data from 205 patients who underwent live-donor nephrectomy: 116 by video-assisted minilaparotomy and 89 by open surgery. Pain and satisfaction were evaluated using scales from 1 to 10, and QoL, with the 36-item Short Form questionnaire. Hospital stay was significantly shorter among the video-assisted (5.1 +/- 1.6 days) than the open group (6.9 +/- 1.3 days; P < .01). Time to resumption of walking without difficulty and normal activity was significantly shorter among the video-assisted than the open group (P<.01). The video-assisted group showed better QoL scores in 6 of 8 QoL categories, including physical role (P < .01), bodily pain (P < .01), general health (P < .01), vitality (P < .01), emotional health (P < .01), and mental health (P < .01). Patients in the video-assisted group (score, 7.3 +/- 2.4) were more satisfied with the cosmetic outcome than those in the open group (score, 5.1 +/- 3.0; P < .01). In conclusion, donors who underwent nephrectomy via video-assisted minilaparotomy showed better outcomes regarding pain, convalescence, cosmesis, and QoL than those who underwent open surgery.
