Mycobacterium sp. (NRRL-B 3683) has been immobilized by adhesion of magnetic materials of submicron size to the bacterial surface. Preparations based on laboratory-prepared magnetic oxide that had been derivatized with hydrophobic octyltrichlorosilane showed the best properties. The magnetically immobilized bacteria were used for side-chain degradation of cholesterol into androsta-1,4-diene-3,17-d
The autonomy created for Åland in 1920 along with the linguistic and cultural guarantees stipulated in the 1921 Åland Agreement established Åland as a monolingual Swedish-speaking province within otherwise bilingual Finland. In particular, the Ålandic municipalities could themselves decide whether Finnish was to be taught in their primary schools. One hundred years later, Åland is still monolingua
Objective: The association between work-related moderate-to-vigorous physical activity (MVPA) and higher levels of stress response is recognized, but whether this association is moderated by regular exercise remains unclear. This cross-sectional study investigated whether exercise-based physical activity (PA) associates with lower levels of stress responses moderated by work-related MVPA. Methods:
Introduction: The CVA24 antigenic variant is the causal agent of epidemics of acute hemorrhagic conjunctivitis that has prevailed to date. To study the transmission dynamics and evolution of this variant, we molecularly characterized Cuban isolates obtained in 5 epidemic periods between 1986 and 2009. Methods: Using the BEAST v1.8.4 program, it was performed the phylogenetic and phylodynamic analy
A screening of immobilized α-chymotrypsin preparations suitable for the synthesis of N-acetyl-L-tyrosine ethyl ester from N-acetyl-L-tyrosine and up to 99% ethanol was carried out. α-Chymotrypsin adsorbed to Sepharose LH-20 or covalently bound to Sepharose 4B (tresyl chloride activation) was found to be an efficient catalyst. A column packed with immobilized enzyme retained 60% of its initial acti
Diabetes remains one of the four major causes of morbidity and mortality globally among non-communicable diseases (NCDs. It is predicted to increase in sub–Saharan Africa by over 50% by 2045. The aim of this study is to identify, map and estimate the burden of diabetes in Ghana, which is essential for optimising NCD country policy and understanding existing knowledge gaps to guide future research
Objectives Critical care is essential in saving lives of critically ill patients, however, provision of critical care across lower resource settings can be costly, fragmented and heterogenous. Despite the urgent need to scale up the provision of critical care, little is known about its availability and cost. Here, we aim to systematically review and identify reported resource use, availability and
Introduction Health technology assessment (HTA) is an area that remains less implemented in low- and lower middle-income countries. The aim of the study is to understand the perceptions of stakeholders in Uganda toward HTA and its role in decision making, in order to inform its potential implementation in the country. Methods The study takes a cross-sectional mixed methods approach, utilizing an a
A new type of support for chromatographic use has been developed. Non-porous quartz fibre, with a mean diameter of 0.5 μm, was silylated with mercaptopropyltrimethoxysilane. Tresyl chloride-activated dextran was covalently coupled to the SH groups on the fibre. Remaining active tresyl groups on the dextran were then coupled with an NAD derivative.The affinity fibre contained 0.3 μmol NAD derivativ
A new technique to speed up the phase separation of aqueous two-phase systems is described. The technique is based on the addition of magnetically susceptible additives (ferrofluids or iron oxide particles). In a magnetic field such additives will induce a faster phase separation. In one approach, dextran-stabilized ferrofluid was added to an aqueous two-phase system containing polyethylene glycol
BACKGROUND: Anemia has been suggested to be related with schooling outcomes in India. Less is known, however, about whether the observed relationship persists after accounting for all household-level factors which may confound the association between anemia and schooling.METHODS: Nationally representative data on adolescents aged 15-18 years with data on measured hemoglobin level and school attend
