Growth Inhibition by Novel Liposomes Including Trehalose Surfactant Ag (...)
Novel liposomes composed of L-α-dimyristoylphosphatidylcholine (DMPC) and trehalose surfactant (DMTreCn) were produced by the method of sonication in buffer solution. The thickness of fixed aqueous layer of DMTreCn was larger than that of DMPC liposomes and increased in a dose-dependent manner. The remarkable inhibitory effects of DMTreCn on the growth of human hepatocellular carcinoma (HCC) (Hep-G2 and HuH-7) cells were obtained along with apoptosis, without affecting the growth of normal cells. DMTreCn induced apoptosis of Hep-G2 and HuH-7 cells through the activation of caspase-3, 8 and 9. Release of cytochrome c from mitochondria and activation of Bcl-2 family protein (BAX) were recorded, indicating that DMTreCn induced apoptosis of Hep-G2 and HuH-7 cells through mitochondrial pathway via BAX. It is noteworthy that the remarkable inhibitory effects of DMTreCn on the growth of human HCC cells were obtained along with apoptosis for the first time.

Trehalose Liposomes Suppress the Growth of Tumors on Human Lung Carcin (...)
Background/Aim: Previous evidence demonstrates that trehalose liposomes (DMTreC14) composed of L-α-dimyristoylphosphatidylcholine (DMPC) and α-D-glycopyranosyl-α-D-glucopyranoside monomyristate (TreC14) inhibit proliferation and invasion on lung carcinoma (A549 cells) in vitro. Here, we aimed to investigate suppressive effects of DMTreC14 on the growth of tumor on human lung carcinoma bearing mice. Materials and Methods: DMTreC14 composed of 30 mol% DMPC and 70 mol% TreC14 were prepared by the sonication method. Anti-tumor activities of DMTreC14 using the subcutaneous and orthotopic graft-bearing mice of A549 cells were investigated in vivo. Results: The remarkable reduction of volume and weight in subcutaneous tumors on subcutaneous lung carcinoma-bearing mice topically administrated with DMTreC14 were obtained. Apoptotic-positive cells in the subcutaneous tumor slice of subcutaneous lung carcinoma-bearing mice topically administrated with DMTreC14 were observed using TUNEL staining. Lung weights on the orthotopic graft-bearing mice of lung carcinoma intravenously administrated with DMTreC14 were markedly decreased compared to those of the control group. Remarkable decrease in dimensions of tumor area of lung on the orthotopic graft-bearing mice of lung carcinoma intravenously administrated with DMTreC14 was obtained in histological analysis using the hematoxylin and eosin staining. Conclusion: Remarkably high anti-tumor activities of DMTreC14 for the subcutaneous and orthotopic graft-bearing mice of lung carcinoma accompanied with apoptosis were revealed for the first time in vivo.

Fucoidan from Undaria pinnatifida regulates type II collagen and COX-2 expression via MAPK and PI3K pathways in rabbit articular chondrocytes Biologia
Fucoidan from Undaria pinnatifida regulates type II collagen and COX-2 expression via MAPK and PI3K pathways in rabbit articular chondrocytes Biologia
Fucoidan is a sulfated polysaccharide widely distributed in brown seaweed. It exhibits several bioactivities, such as anti-cancer, anti-tumor, anti-microbial, anti-diabetic and anti-oxidant properties. However, the effects of fucoidan in chondrocytes are not well established. Previously, we have reported in vitro and in vivo anti-inflammatory effects of fucoidan. In this study, we evaluated the effects and regulatory mechanism of fucoidan derived from Undaria pinnatifida on the cyclooxygenase-2 (COX-2) and type II collagen in rabbit articular chondrocytes. Using western blotting and alcian blue staining, respectively, fucoidan was shown to induce type II collagen and sulfated proteoglycan in a dose- and time-dependent manner. Moreover, fucoidan inhibited the COX-2 expression in a dose- and time-dependent manner and increased the phosphorylation of extracellular signal-regulated kinase (ERK), p38, and AKT kinases in chondrocytes. The inhibition of p38 and AKT using SB203580 and LY294002, respectively, in the presence of fucoidan decreased the expression of type II collagen. However, ERK inhibition using PD98050 stimulated type II collagen expression. Fucoidan increased COX-2 expression in the presence of inhibitors of ERK, p38, and AKT kinases. These results conclusively suggested that fucoidan regulated type II collagen expression via the p38 and AKT pathways, and COX-2 expression via the p38, ERK and AKT pathways in rabbit articular chondrocytes. Moreover, given its ability to mediate cell differentiation and exert anti-inflammatory activity, fucoidan may represent a potential therapeutic substance for use in inflammatory conditions, including arthritis.

COVID-19 Update 70 with Roger Seheult, MD Our Update 71 is available at https://www.medcram.com/courses/coronavirus-outbreak-symptoms-treatment As many states in the US make arrangements to re-open their economies, Dr. Seheult discusses some recent trends in COVID-19 infections and deaths. Glutathione is a substance produced naturally by the liver- and is also found in vegetables, fruits, and meats. Dr. Seheult discusses some interesting case reports from New York and Russia that suggest glutathione deficiency may be related to COVID-19 severity. More studies are needed to assess if supplementation of NAC and glutathione could aid in the prevention and treatment of COVID-19 (This video was recorded May 14th, 2020) ------------------------------------------- Links referenced in this video: Johns Hopkins Tracker - https://coronavirus.jhu.edu/map.html https://www.worldometers.info/coronavirus/ HHS - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2999661/ ABC - https://abcnews.go.com/Business/states-coronavirus-reopening-plan/story?id=70565409 US News - https://www.usnews.com/news/health-news/articles/2020-05-12/covid-19-now-reaching-into-rural-america Reuters - https://graphics.reuters.com/HEALTH-CORONAVIRUS/USA-TRENDS/dgkvlgkrkpb/ ResearchGate (Dr. Polonikov from Russia) - https://www.researchgate.net/publication/340917045_Endogenous_deficiency_of_glutathione_as_the_most_likely_cause_of_serious_manifestations_and_death_in_patients_with_the_novel_coronavirus_infection_COVID-19_a_hypothesis_based_on_literature_data_and_ow ClinicalTrials - https://clinicaltrials.gov/ct2/show/NCT04374461 Circulation - https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.117.027290 Medicine - https://journals.lww.com/md-journal/FullText/2018/11090/N_acetylcysteine_improves_oxidative_stress_and.35.aspx NIH - https://pubmed.ncbi.nlm.nih.gov/32322478/?from_term=glutathione+coronavirus&from_pos=9 New York Post - https://nypost.com/2020/05/09/new-york-mom-with-coronavirus-saved-by-medical-student-son/ ------------------------------------------- Some previous videos from this series (visit MedCram.com for the full series): - Coronavirus Pandemic Update 71: New Data on Adding Zinc to Hydroxychloroquine + Azithromycin: https://www.medcram.com/courses/coronavirus-outbreak-symptoms-treatment - Coronavirus Pandemic Update 69: "NAC" Supplementation and COVID-19 (N-Acetylcysteine) https://youtu.be/Dr_6w-WPr0w - Coronavirus Pandemic Update 68: Kawasaki Disease; Minority Groups & COVID-19: https://youtu.be/Ja-jhcXMGj0 - Coronavirus Pandemic Update 67: COVID-19 Blood Clots - Race, Blood Types, & Von Willebrand Factor https://youtu.be/JOlVkES_kC8 - Coronavirus Pandemic Update 66: ACE-Inhibitors and ARBs - Hypertension Medications with COVID-19 https://youtu.be/OudhmwulJHY - Coronavirus Pandemic Update 65: COVID-19 and Oxidative Stress (Prevention & Risk Factors) https://youtu.be/gzx8LH4Fjic - Coronavirus Pandemic Update 64: Remdesivir COVID-19 Treatment Update https://youtu.be/Z2hfGcTokiY - Coronavirus Pandemic Update 63: Is COVID-19 a Disease of the Endothelium (Blood Vessels and Clots)? https://youtu.be/Aj2vB_VITXQ - Coronavirus Pandemic Update 62: Treatment with Famotidine (Pepcid)? https://youtu.be/DtPwfihjyrY - Coronavirus Pandemic Update 61: Blood Clots & Strokes in COVID-19; ACE-2 Receptor; Oxidative Stress https://youtu.be/22Bn8jsGI54 - Coronavirus Pandemic Update 60: Hydroxychloroquine Update; NYC Data; How Widespread is COVID-19? https://www.medcram.com/courses/coronavirus-outbreak-symptoms-treatment - Coronavirus Pandemic Update 59: Dr. Seheult's Daily Regimen (Vitamin D, C, Zinc, Quercetin, NAC) https://youtu.be/NM2A2xNLWR4 - Coronavirus Pandemic Update 58: Testing; Causes of Hypoxemia in COVID 19 (V/Q vs Shunt vs Diffusion) https://youtu.be/nO4xgcIaPeA - Coronavirus Pandemic Update 57: Remdesivir Treatment Update and Can Far-UVC Disinfect Public Spaces? https://www.medcram.com/courses/coronavirus-outbreak-symptoms-treatment All coronavirus updates are at MedCram.com (including a discussion of that data for coronavirus UK, coronavirus NYC, and other locations) and we offer many other medical topics (ECG Interpretation, strokes, thrombosis, pulmonary embolism, myocardial infarction, hypercoagulation, hypertension, anticoagulation, DKA, acute kidney injury, influenza, measles, mechanical ventilation, etc.). ------------------------------------------- Speaker: Roger Seheult, MD Board Certified in Internal Medicine, Pulmonary Disease, Critical Care, and Sleep Medicine.
