In all assays, FA itself did not exert any effect on the change of the above parameters. These novel findings indicated that FA effectively protected human ARPE-19 cells from H2 O2 -induced oxidative damage through its pro-proliferation, anti-apoptosis and antioxidant activity, suggesting that FA has a therapeutic potential in the prevention and treatment of AMD.Acute ischemic stroke is one of the leading causes of death in developed countries and the most common cause of disability in adults worldwide. Despite advances in the understanding of stroke pathophysiology, therapeutic options remain limited. In this study, we explored the interaction of Shrm4 and the metabotropic gamma-aminobutyric acid (GABA) receptors (GABAB ) in ischemic stroke. A transient middle cerebral artery occlusion (MCAO) model was induced by filament insertion in Shrm4+/+ and wild-type C57BL/6J mice, followed by reperfusion for up to 7 days. Baclofen was administered was used to activate GABAB in vivo during reperfusion. Neurological deficits, motor and memory functions, and infarct volume were determined in the various mouse groups. VPS34 inhibitor 1 nmr Furthermore, we also developed an oxygen-glucose deprivation (OGD) cell model in primary neurons to test Shrm4/GABAB interactions in vitro. Shrm4 was observed to decrease infarct volume and neuronal cell loss in penumbra, and rescue neurological deficits in MCAO mice. Notably, Shrm4 also increased pole climbing speed, reduced foot faults, and increased escape latency in the Morris water maze test, while reducing neuron autophagy through an interaction with GABAB receptors. GABAB activation using baclofen further reduced OGD-induced neuron damage in culture and stroke outcomes of MCAO, relative to Shrm4 alone. Taken together, Shrm4-mediated GABAB activation confers neuroprotection by reducing neuronal autophagy in acute ischemic stroke.Niemann-Pick disease type C (NPC) is a severe disorder that is characterized by intracellular transport abnormalities leading to cytoplasmic accumulation of lipids such as cholesterol and sphingolipids. The compound 2-hydroxypropyl-β-cyclodextrin (HPβCD) has high cholesterol complexation capacity and is currently under clinical investigation for the NPC treatment. However, due to its short blood half-life, high doses are required to produce a therapeutic effect. In this work, stable polymerized HPβCD is generated to investigate their in vitro mechanisms of action and in vivo effects. Crosslinked CDs (8-312 kDa) display a ninefold greater cholesterol complexation capacity than monomeric HPβCD but are taken up to a lower extent, resulting in an overall comparable in vitro effect. In vivo, the 19.3 kDa HPβCD exhibits a longer half-life than the monomeric HPβCD but it does not increase the life span of Npc1 mice, possibly due to reduced brain penetration. This is circumvented by the application of magnetic resonance imaging-guided low intensity-pulsed focused ultrasound (MRIg-FUS), which increases the brain penetration of the CD. In conclusion, stable polymerized HPβCDs can elucidate CDs' mechanism of action while the use of MRIg-FUS warrants further investigation, as it may be key to harnessing CDs full therapeutic potential in the NPC treatment.Natural glycoconjugates that form glycocalyx play important roles in various biological processes based on cell surface recognition through pattern recognition mechanisms. This work represents a new synthesis-based screening strategy to efficiently target the cancer cells by higher-order glycan pattern recognition in both cells and intact animals (mice). The use of the very fast, selective, and effective RIKEN click reaction (6π-azaelectrocyclization of unsaturated imines) allows to synthesize and screen various structurally well-defined glycoalbumins containing two and eventually four different N-glycan structures in a very short time. The importance of glycan pattern recognition is exemplified in both cell- and mouse-based experiments. The use of pattern recognition mechanisms for cell targeting represents a novel and promising strategy for the development of diagnostic, prophylactic, and therapeutic agents for various diseases including cancers.The leading cause of central vision loss, age-related macular degeneration (AMD), is a degenerative disorder characterized by atrophy of retinal pigment epithelium (RPE) and photoreceptors. For 15% of cases, neovascularization occurs, leading to acute vision loss if left untreated. For the remaining patients, there are currently no treatment options and preventing progressive RPE atrophy remains the main therapeutic goal. Previously, we have shown treatment with interleukin-33 can reduce choroidal neovascularization and attenuate tissue remodelling. Here, we investigate IL-33 delivery in aged, high-fat diet (HFD) fed mice on a wildtype and complement factor H heterozygous knockout background. We characterize the non-toxic effect following intravitreal injection of IL-33 and further demonstrate protective effects against RPE cell death with evidence of maintaining metabolic retinal homeostasis of Cfh+/-~HFD mice. Our results further support the potential utility of IL-33 to prevent AMD progression.
Sentinel lymph node biopsy (SLNB) of primary cutaneous melanoma as an important staging method has not been popularly undertaken in Korea and only a few studies with small patient numbers have been published.

We examined the clinical feasibility and overall outcomes of SLNB in acral melanoma (AM) of Korean in Kyungpook National University Hospital (KNUH) over the past 13 years.

SLNB in AM patients during 2006-2018 were analyzed retrospectively for sentinel lymph node (SLN) harvesting rate, positivity rate, positivity-relevant overall survival (OS) and disease-free survival (DFS), and its side effects.

A total of 109 AM patients who underwent SLNB were enrolled. Harvested nodes were identified from 107 patients and SLN harvesting rate was 98.2%. The mean Breslow thickness (±standard deviation) was 3.38 ± 3.03mm, and the proportion of ulcerated melanomas was 64%. Twenty-two (20.6%) had a tumor-positive SLN and, among them, 82% (18/22) underwent immediate complete lymph node dissection (CLND). The metastasis-positive nodal basin after CLND was detected in 16.
