The postharvest saving of Ngoc Linh ginseng ( NL nin-sin ) is essential to retain its timber and sensory values for extended storage . In this study , the efficaciousness of NL nin-sin preservation by surfacing chitosan derivatives in combining with polyvinyl intoxicant ( PVA ) solutions was inquired under infrigidation conditions ( ~3 °C ; ~40 % RH ) for 56 days . The effect of the chitosan-based results , admiting N , O-carboxymethyl chitosan ( NOCC ) , chitosan oligomer sugar ( COS ) , or chitosan ( CS ) , and the blend roots ( NOCC-PVA or COS-PVA ) on the coated NL ginsengs was observed during depot . The pH values , viscosity , and film-forming capableness of the surfacing roots were settled , while the optic appearance , morphology , and mechanical properties of the celluloids formed on spyglass substratums as a nin-sin model for coating were also respected . The appearing , skin lightness , weight loss , sensory rating , total saponin content ( TSC ) , total polyphenol content ( TPC ) , and full antioxidant capacity ( TAC ) of the coated NL nin-sins were evaluated . The findings pointed that the discovered values of the coated NL nin-sins were salutary than those of the non-coated samples , with the exception of the COS-coated samples , which had completely negative results the NOCC-PVA root exhibited a better preservation effect compared with the COS-PVA one founded on the ascertained indices , except for TPC and TAC , which were not affected by the coating the optimal conservation time was limited to be 35 days .
This report exhibits promising preservation technology applying the coating solution of NOCC-PVA , ruling the synergetic effect of pH 7 and the form-firming capability , to observe the ledge life , medicinal content , and centripetal attributes of NL ginseng.Vitamin K2 subjoining and the progression of abdominal aortic calcification in dialysis patients.OBJECTIVES : Vascular calcification is common in patients with advanced inveterate kidney disease ( CKD ) and bestows to cardiovascular disease . Accumulating ground indicates that CKD patients often acquire subclinical vitamin K deficiency , which is connected with vascular calcification This prospective , randomised , parallel grouping , multicenter trial ( UMINID000011490 ) will admit 200 dialysis patients in an open-label , two-arm purpose . After baseline computed imaging of the abdominal aorta , patients will be randomized to two radicals that will either ( 1 ) continue receiving banner care or ( 2 ) receive extra oral supplementation with menatetrenone ( 45 mg/day ) . The discourse continuance will be 24 months , and the computed tomography scan will be retelled after 12 and 24 months . The elementary endpoint is the advancement of abdominal aortic calcification , which is calculated as absolute changes established on the Agatston grade .
The lower-ranking endpoints are the decrease in bone mineral density ( valuated by dual-energy X-ray absorptiometry ) , the biomarkers linked with vitamin K , vitamin K intake ( assessed by the food frequency questionnaire ) , and the biomarkers linked with vascular calcification This work aims to support whether vitamin K has inhibitory consequences on calcification that can be clinically determined . tryout REGISTRATION : UMINID000011490.Enhanced vitamin K2 production by engineered Bacillus subtilis during leakage fermentation.Menaquinone-7 ( MK-7 ) , a worthful member of the vitamin K2 serial , is an essential nutrient for homos . It is used for treating coagulation disorders , and osteoporosis , advancing liver function recovery , and forestalling cardiovascular diseases . In this bailiwick , to further amend the metabolic synthesis of MK-7 by the mutant stock , the effect of surfactants on the metabolic synthesis of MK-7 by the mutant strain Bacillus subtilis 168 KO-SinR ( BS168 KO-SinR ) was studied . The scanning electron microscopy and flow cytometry resultants expressed that the addition of surfactants modified the permeableness of the cell membrane of the mutant strain and the structural components of the biofilm .
When 0 % Tween-80 was supplied into the metier , the extracellular and intracellular deduction of MK-7 reached 28 mg/L and 59 mg/L , severally , increasing the entire synthesis of MK-7 by 80 % .Get it now
