Background The new global target for maternal mortality ratio (MMR) is a ratio below 70 maternal deaths per 100 000 live births by 2030. We undertook a systematic review of methods used to measure MMR in low- and middle-income countries. Sources of data Systematic review of the literature; 59 studies included. Areas of agreement Civil registration (5 studies), census (5) and surveys (16), R...

Abstract Background In view of the natural resistance hemicelluloses in lignocellulosic biomass on bioconversion cellulose into fermentable sugars, alkali extraction is considered as an effective method for gradually fractionating and increasing efficiency cellulose. present study, sequential alkaline extractions were performed delignified ryegrass material to achieve high comprehensively inves...

the aim of this reaserch was evaluathng the aluminum-sulphate concentration levels in preserved solution with stem recutting on longevity of rosa hybrida cv. varlon cut flowers. the investigation was conducted in horticultural lab,agriculturalcollege,zanjanuniversity. rose cut stems were produced in greenhouse from biennial mother stocks and were placed under the treatment of aluminum-sulphate ...

UNLABELLED PREMISE OF THE STUDY The chemical diversity of land plants ensures that no single DNA isolation method results in high yield and purity with little effort for all species. Here we evaluate a new technique originally developed for forensic science, based on MagnaCel paramagnetic cellulose particles (PMC), to determine its efficacy in extracting DNA from 25 plant species representin...

Background & Aim: Aloe vera is used in the food and pharmaceutical as an aid to effective treatment. The purpose of this study is to improve growth, increase production of valuable metabolites and increase the sugars in Aloe vera gel with low cost and high efficiency under water stress conditions. Experimental: In this study, Aloe vera potted in greenhouse conditions...

BACKGROUND Carbohydrate binding modules (CBMs) bind polysaccharides and help target glycoside hydrolases catalytic domains to their appropriate carbohydrate substrates. To better understand how CBMs can improve cellulolytic enzyme reactivity, representatives from each of the 18 families of CBM found in Ruminoclostridium thermocellum were fused to the multifunctional GH5 catalytic domain of CelE...

Polysaccharide is widely distributed in natural resources, and currently attracts scientists' attention for their various bio-functions including immunomodulatory activity, hypoglycemic hypolipidemic antitumor promoting effects on gastrointestinal function, so on. The purity structure characteristics of different polysaccharides greatly restrict the in-depth study bioactivity mechanism. Therefo...
