Iron is essential to plants for chlorophyll formation as well as for the functioning of various iron-containing enzymes. Iron deficiency chlorosis is a wide-spread disorder of plants, in particular, of those growing on calcareous soils. Among the different ways to control iron deficiency problems for crops, plant material and especially ...

Children with Down syndrome (DS) and acute lymphoblastic leukemia (ALL) have an inferior prognosis compared to non-DS ALL patients. We reviewed Methotrexate (MTX)/Mercaptopurine (6MP) maintenance therapy data for children with DS treated according to the NOPHO ALL92 or the NOPHO ALL2000 protocols between 1992 and 2007. The five year event-free ...

BACKGROUND: Long-term sickness absence (LTSA) is most commonly due to common mental disorders and symptom-based conditions. Relatively little research has examined individual, as opposed to occupational, risk factors for LTSA. Individual appraisal of the workplace has been considered in several studies but self-rated health has more often been examined as ...

Cardiorenal syndrome is a condition in which a complex interrelationship between cardiac dysfunction and renal dysfunction exists. Despite advances in treatment of both cardiovascular and kidney disease, cardiorenal syndrome remains a major global health problem. Characteristic of the pathophysiology of cardiorenal syndrome is bidirectional cross-talk; mediators/substances activated by the disease ...

Parahydrogen induced polarisation (PHIP) has wide utility in NMR and MRI as it can increase the sensitivity of both techniques. The transfer of spin order from parahydrogen to nuclei in the analyte leads to an increased magnetic response following interrogation by RF pulses. This spin transfer is catalysed by a ...

We studied peculiarities of the structural reconstruction within holographically recorded gratings on the surface of several different amorphous azobenzene-containing polymers. Under illumination with a light interference pattern, two processes take place in this type of polymer. The first process is the light-induced orientation of azobenzene units perpendicular to the polarization ...

Tuberculosis is a dreadful disease that results in innumerable deaths across the world that is caused by bacterium Mycobacterium tuberculosis. Emergence of multi drug resistance (MDR) and extremely drug resistance tuberculosis (XDR) strains and its co-infection with HIV has made tuberculosis more difficult to treat. Therefore, new anti-mycobacterial agent(s) for ...

A simple method of room temperature phosphorescence is proposed for the determination of propranolol enantiomeric composition based on β-cyclodextrin as the chiral host and bromocyclohexane as the heavy atom. Enantiomeric complexes are formed upon binding of the propranolol enantiomer to β-cyclodextrin, and the sign of the resultant phosphorescence signals allows ...

Zoonotic disease surveillance is typically initiated after an animal pathogen has caused disease in humans. Early detection of potentially high-risk pathogens within animal hosts may facilitate medical interventions to cope with an emerging disease. To effectively spillover to a novel host, a pathogen may undergo genetic changes resulting in varying ...

General principles about the consequences of seed dispersal by animals for the structure and dynamics of plant populations and communities remain elusive. This is in part because seed deposition patterns emerge from interactions between frugivore behaviour and the distribution of food resources, both of which can vary over space and ...

Carbonic anhydrases (CAs, EC 4.2.1.1) are a family of metalloenzymes that catalyze the reversible interconversion of CO(2) and HCO(3)(-). Of the 15 isoforms of human (h) α-CA, 12 are catalytic (hCAs I-IV, VA, VB, VI, VII, IX, XII-XIV). The remaining three acatalytic isoforms (hCAs VIII, X and XI) lack the ...

BACKGROUND: Heart transplantation is an alternative for individuals with end-stage heart disease. However, episodes of heart rejection (HR) are frequent and increase morbidity and mortality, requiring the use of an accurate non-invasive exam for their diagnosis, since endomyocardial biopsy (EMB) is not a complication-free procedure. OBJECTIVE: To compare the parameters ...

β-Catenin is essential for muscle development because it regulates both cadherin-mediated cell-cell adhesion and canonical Wingless and Int1 (Wnt) signaling. The phosphorylation of β-catenin by glycogen synthase kinase-3β (GSK-3β) at serine31/37/threonine41 regulates its stability and its role in canonical Wnt signaling. In this study, we have investigated whether the N-terminal ...

Protein-RNA interactions are fundamentally important in understanding cellular processes. In particular, non-coding RNA-protein interactions play an important role to facilitate biological functions in signalling, transcriptional regulation, and even the progression of complex diseases. However, experimental determination of protein-RNA interactions remains time-consuming and labour-intensive. Here, we develop a novel extended naïve-Bayes-classifier ...

Preservation of the meniscus and consideration for repair is important when treating meniscal tears. Many techniques for repair have been described. At present, all-inside, suture anchor-based meniscal repair systems are widely used. Arthroscopic all-inside hybrid meniscal suturing has been shown to have a low complication rate as the suture anchors ...
