Hypocholesterolemic effect of sericin-derived oligopeptides in high-cholesterol fed rats

AbstractThe beneficial effect of cholesterol-lowering proteins and/or peptides derived from various dietary sources is continuously reported. A non-dietary protein from silk cocoon, sericin, has also demonstrated cholesterol-lowering activity. A sericin hydrolysate prepared by enzymatic hydrolysis was also expected to posses this effect. The present study was aimed at investigating the cholesterol-lowering effect of sericin peptides, so called “sericin-derived oligopeptides” (SDO) both in vivo and in vitro. The results showed that SDO at all three doses tested (10 mg kg−1 day−1, 50  mg kg−1 day−1, and 200  mg kg−1 day−1) suppressed serum total and non-HDL cholesterol levels in rats fed a high-cholesterol diet. Triglyceride and HDL-cholesterol levels were not significantly changed among all groups. The fecal contents of bile acids and cholesterol did not differ among high-cholesterol fed rats. SDO dose-dependently reduced cholesterol solubility in lipid micelles, and inhibited cholesterol uptake in monolayer Caco-2 cells. SDO also effectively bound to all three types of bile salts including taurocholate, deoxytaurocholate, and glycodeoxycholate. Direct interaction with bile acids of SDO may disrupt micellar cholesterol solubility, and subsequently reduce the absorption of dietary cholesterol in intestines. Taking all data together, SDO or sericin peptides exhibit a beneficial effect on...

ConclusionWe provide an overview of mortality related to SE in China as the HQMS database covers a large number of cases of SE in China, making it one of the most efficient tools for mortality investigation. The use of electronic medical records in China creates several challenges and here we discuss lessons learned. The methodology will be improved and will be used in future studies.

One example of this phenomenon is the ability to discriminate colors in the absence of awareness. These so-called patients with blindsight must have a neural pathway that bypasses V1, explaining their ability to unconsciously process stimuli. The pathways that have been most often hypothesized to be the cause of blindsight connec...

ConclusionData from this large, long-term study indicate that the nature, character, and frequency of SAEs in real-world settings are consistent with natalizumab's known safety profile. (Funded by Biogen; ClinicalTrials.gov identifiers: NCT00477113 and NCT00483847.)

This study examined the impact of psychiatric comorbidity on QOL in patients admitted to two level 4 epilepsy monitoring units (EMUs).MethodsIn this prospective observational study, 200 patients admitted to two level 4 EMUs completed standardized surveys including the Quality of Life in Epilepsy (QOLIE-31-P), Generalized Anxiety Disorder 7-item (GAD-7), Patient Health Questionnaire (PHQ-9), and Beck Depression Inventory-II (BDI-II). Hierarchal multiple regression was performed to assess impact on QOL.ResultsOf the 200 participants, 113 had a diagnosis of epilepsy, 36 had a diagnosis of PNES, and 51 were excluded for nondia...

Verbal impairments observed during the postictal period may be studied to help localizing the epileptogenic zone. These explorations have been essentially based on simple tasks focused on speech, thus disregarding t...

ConclusionPatients and physicians' priorities in the management of epilepsy overlap only in part. Patients are satisfied with their caring physicians and less satisfied with communication and management of routine and emergency problems.
