With 4 mg folic acid daily, it may take 20 weeks to reach red-blood-cell folate levels between 1,050 and 1,340 nmol/L, optimal for reduction of the neural tube defect risk. Therefore, folic acid supplementation should be started 5-6 months before conception. The residual risk with optimal red-blood-cell folate levels is reportedly 4.5 per 10,000 total births. The residual risk in pooled data from countries with mandatory folic acid fortification is 7.5 per 10,000 pregnancies, regardless of pre-fortification rates...

Genes responsible for the production of azoreductase enzymes in 2 g negative bacteria, the soil bacterium Pseudomonas putida (AzoP) and the plant pathogen Xanthomonas oryzae (AzoX), were identified. The deduced amino acid sequences of AzoP and AzoX, share 46% amino acid identity to each other. Two different bacterial transcription factors, a repressor (AzoPR) and an activator (AzoXR), in P. putida and X. oryzae, respectively, were found to be divergently oriented to their respective azoreductase genes. Both regulators are LysR-type transcriptional regulators (LTTR) that respond to the azo dye inducer, methyl red (MR)...

EML4-ALK gene fusion (inv2(p21p23)) of non-small cell lung cancer (NSCLC) predisposes to tyrosine kinase inhibitor treatment. One of the gold standard diagnostics is the dual color (DC) break-apart (BA) FISH technique, however, the unusual closeness of the involved genes has been suggested to raise likelihood of random co-localization (RCL) of signals. Although this is suspected to decrease sensitivity (often to as low as 40-70%), the exact level and effect of RCL has not been revealed thus far. Signal distances were analyzed to the 0...

Humic substances (HSs) can influence the growth and composition of freshwater phytoplankton assemblage. Since HSs contain many phenolic and quinonic moieties and cause growth reductions in eco-physiological field experiments, HSs are considered photosystem II herbicides. To test this specific mode of action in vivo and in vitro, respectively, we used intact cells of the green alga Desmodesmus armatus, as well as thylakoids isolated from spinach (Spinacia oleracea) as a model system for the green algal chloroplast...

Novel hemoglobin-based artificial oxygen carriers are necessary in tissue engineering. We developed human hemoglobin (hHb) and albumin (HSA)-based microspheres using Shirasu porous glass (SPG) membrane emulsification. The obtained microspheres had a uniform size with an average diameter of 15.1 μm measured by optical microscope, which is similar to the diameter of human red blood cells (7-8 μm). The loading amount of hHb in the microspheres was 20 wt%, which is similar to that of red blood cells (33 wt%)...

Virtually all the red blood cell and platelet antigen systems have been characterized at the molecular level. Highly reliable methods for red blood cell and platelet antigen genotyping are now available. Genotyping is a useful adjunct to traditional serology and can help resolve complex serologic problems. Although red blood cell and platelet phenotypes can be inferred from genotype, knowledge of the molecular basis is essential for accurate assignment. Genotyping of blood donors is an effective method of identifying antigen-negative and/or particularly rare donors...

BACKGROUND: Randomized controlled trials have demonstrated that a restrictive red blood cell (RBC) transfusion strategy lowers transfusion frequency without affecting mortality. However, the external validity of these trials has not been tested in a large cohort. The purpose was to estimate the effect of introducing a National Clinical Guideline (NCG) for a restrictive hemoglobin transfusion threshold on transfusion frequency and mortality in hip fracture patients > 65 years old...

Regardless of the malaria disease risk, the malaria parasite Plasmodium falciparum has an interesting mechanism. During its growth within the red blood cell, toxic free heme is converted into an insoluble crystalline form called the malaria pigment, or hemozoin. In particular, natural hemozoin nanocrystals can provide multiple applications in biosensing fields for health care and diagnosis as similar to artificial metal nanoparticles. In this study, the heme was biologically synthesized and polymerized by Corynebacterium glutamicum and final polymer was applied as a biomimetic conductive biopolymer...

Obesity due to excessive lipid accumulation is closely associated with metabolic diseases such as type 2 diabetes, insulin resistance and inflammation. Therefore, a detailed understanding of the molecular mechanisms that underlie adipogenesis is crucial to develop treatments for diseases related to obesity. Here, we found that the microRNA-204-5p (miR-204-5p) was expressed at low levels in fat tissues from obese mice fed long-term with a high-fat diet (HFD). Overexpression or inhibition of miR-204-5p in vitro in 3T3-L1 preadipocytes significantly inhibited or promoted 3T3-L1 proliferation, respectively, an effect mediated by regulating cell proliferation factors...

Many studies have assessed the effects of incorporation of plant feedstuffs in fish diets on growth performance, whereas few studies have addressed the effects of fish meal replacement by plant protein sources on fish immune parameters. Thus, the aim of this study was to evaluate the effects on immune response of different inclusion levels of carob seed germ meal (CSGM) as partial replacement for fish meal in diets for meagre (Argyrosomus regius) juveniles. Fish were fed four experimental diets with increased CSGM inclusion levels [0% (control), 7...

Anaemia is a condition in which the haemoglobin concentration falls below an established cut-off value due to a decrease in the number and size of red blood cells. The current study aimed (i) to assess the spatial pattern and (ii) to identify determinants related to anaemia using the third Ethiopian demographic health survey. To achieve these objectives, this study took into account the sampling weight and the clustered nature of the data. As a result, multilevel modeling has been used in the statistical analysis...

Photocages are light-sensitive chemical protecting groups that provide external control over when, where, and how much of a biological substrate is activated in cells using targeted light irradiation. Regrettably, most popular photocages (e.g. o-nitrobenzyl groups) absorb cell-damaging ultraviolet wavelengths. A challenge with achieving longer wavelength bond-breaking photochemistry is that long-wavelength-absorbing chromophores have shorter excited state lifetimes and diminished excited state energies. However, here we report the synthesis of a family of BODIPY-derived photocages with tunable absorptions across the visible/near-IR that release chemical cargo under irradiation...

OBJECTIVE Blunt traumatic extracranial carotid or vertebral artery injury (i.e., traumatic cerebrovascular injury [TCVI]) occurs in 1%-2% of all blunt trauma admissions, carries a 10% risk of thromboembolic ischemic stroke, and accounts for up to 9600 strokes annually in the US. Screening CT angiograms (CTAs) of patients with trauma has become ubiquitous in recent years, and patients with initially asymptomatic TCVI are commonly treated with antiplatelet agents to prevent stroke. Prophylaxis with antiplatelets is thought to be safer than anticoagulation, which carries a significant risk of hemorrhage in patients with trauma...

pH responsive luminescent copper nanoclusters (Cu NCs) with aggregation induced emission (AIE) characteristics have been synthesized. Upon internalization into living cells, the NCs displayed cellular pH environment dependent luminescence change with orange-red emission at pHi 4.5 while bright green emission was observed over time at pHi 7.4, through their AIE attributes. Further, the intracellular AIE kinetics of the NC probe was measured in MCF-7 cells and compared with HEK-293 cells. Intriguingly, intracellular rate constant value derived for AIE kinetics in MCF-7 cells was found 3-fold higher than that in HEK-293 cell lines, whereas the value was 2-fold higher than that observed in the aqueous medium...
