Molasses is a sugar mill by-product with low value that today is used primarily for animal feed. However, molasses contains large amounts of sucrose which, if purified, could be used for other purposes. In this study, purification by membrane filtration using ceramic tubular ultrafiltration (UF) and nanofiltration (NF) was examined. NF purifies sucrose by removing small compounds, whereas UF remov
To avoid discomfort, health care professionals may hesitate to pursue conversations about end of life with patients. Certain tools have the potential to facilitate smoother conversations in this matter. The objective was to explore the experiences of patients in palliative care in using statement cards to talk about their wishes and priorities. Forty-six cards with statements of wishes and priorit
BACKGROUND: The study investigated whether 3D vision and haptic feedback in combination in a virtual reality environment leads to more efficient learning of laparoscopic skills in novices.MATERIAL AND METHODS: Twenty novices were allocated to two groups. All completed a training course in the LapSim(®) virtual reality trainer consisting of four tasks: 'instrument navigation', 'grasping', 'fine dis
Neurotrophic factors regulate survival and growth of neurons. The urinary bladder is innervated via both sympathetic and parasympathetic neurons located in the major pelvic ganglion. The aim of the present study was to characterize the effects of the neurotrophins nerve growth factor (NGF), brain derived neurotrophic factor (BDNF) and neurotrophin 3 (NT-3) on the sprouting rate of sympathetic and
The core feature of vascular ageing is the age-associated stiffening of the large, elastic arteries, or arteriosclerosis. This results in a diminished volume-buffering function and is therefore central for the increase in systolic blood pressure and pulse pressure seen with advancing age. Since there are considerable individual differences regarding the rate of vascular ageing, the aim was to desc
Energy-intensive processing industries like the concrete industry form the base of the economy and account for a large part of global greenhouse gas emissions. Sectoral transformation to cleaner basic materials is therefore crucial, and institutional pressure to do so is increasing. However, socio-technical studies have not sufficiently addressed these sectors. This paper therefore sets out to ana
We investigated the role of dopamine neurons in the manifestation of levodopa-induced dyskinesia in a rat model of Parkinson's disease. Daily treatment with a subthreshold dose of levodopa gradually induced abnormal involuntary movements (AIM) in 6-hydroxydopamine-lesioned rats, which included stereotypy and contraversive rotation. After 4 weeks of levodopa treatment, rats with mild and severe AIM
Objectives Belimumab is the first biologic drug approved for Systemic Lupus Erythematosus (SLE). Here, we aimed to investigate the effects of belimumab on clinical and serologic outcomes, and sought to identify predictors of treatment response in three Swedish real-life settings. Methods Fifty-eight patients were enrolled at initiation of belimumab and followed longitudinally for up to 53 months.
Bacterial drug resistance is a serious concern for human health. Multidrug efflux pumps export a broad variety of substrates out of the cell and thereby convey resistance to the host. In Escherichia coli, the AcrB:AcrA:TolC efflux complex forms a principal transporter for which structures of the individual component proteins have been determined in isolation. Here, we present the X-ray structure o
1. We estimated the correlation between host phylogeographical structure and beta diversity of avian haemosporidian assemblages of passerine birds to determine the degree to which parasite communities change with host evolution, expressed as genetic divergence between island populations, and we investigated whether differences among islands in the haemosporidia of a particular host species reflect
OBJECTIVES: Untreated primary hyperarathyroidism (pHPT) is accompanied by an excessive morbidity in circulatory disorders, associated with blood pressure and diabetes. The aim of the present study was to further penetrate the impact of pHPT on glucose, urate, lipid and lipoprotein concentrations, known to be interrelated metabolic cardiovascular risk factors.DESIGN: Longitudinal study of patients
BACKGROUND: The distinction between solitary parathyroid adenoma and hyperplasia can sometimes be difficult during surgery for primary hyperparathyroidism (pHPT), especially in patients who have undergone previous thyroid or parathyroid surgery. The use of intraoperative parathyroid hormone (PTH) monitoring as a possible diagnostic tool was therefore investigated.METHODS: Intraoperative levels of
Unilateral neck exploration for primary hyperparathyroidism (pHPT) of old and high risk patients can be safely performed under local anesthesia, provided there is a correct preoperative side localization of the enlarged parathyroid gland. We performed large vein sampling and measured intact parathyroid hormones (PTH) with a new, highly sensitive immunoradiometric assay. The method was used before
