Morphological and Immunophenotypic Clues to the WHO Categories of Acute Myeloid Leukaemia

Diagnosis and classification of acute myeloid leukaemia (AML) require cytogenetic and molecular genetic investigation. However, while these evaluations are pending, morphology supplemented by immunophenotyping can provide clues to the diagnosis of specific cytogenetic/genetic categories of AML. Most importantly, acute promyelocytic leukaemia can be diagnosed with a high degree of certainty. However, provisional identification of cases associated with t(8; 21), inv(16), t(1; 22), and NPM1 mutation may also be possible. In addition, transient abnormal myelopoiesis of Down’s syndrome can generally be diagnosed morphologically.
Effects of Wood Ash on Nutrients and Heavy Metal(oid)s Mobility in an Ultisol

Wood ash produced through cellulose manufacturing has agricultural uses due to its neutralizing power, like that of commercial products, in addition to providing key soil nutrients such as Ca, Mg, K, and P. However, this industrial waste can possess heavy metal(oid)s that bioaccumulate in the food chain. The objective of this study was to determine the effect of wood ash (WA) on the physicochemical properties of an Ultisol, the mobility of heavy metal(oid)s (As, Cd, Cr, Pb, and Ni) in the soil-plant-water system, and the nutritional response (N, P, and K) of ryegrass (Lolium perenne L.). The experiment was conducted in pots, under greenhouse conditions, using a completely randomized design. Ryegrass was grown in pots containing mixtures of WA plus soil at 7.5, 15, 30, and 75 g kg−1, commercial lime plus soil at 1.5 g kg−1, and unamended soil as a control. Heavy metal(oid)s were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES). All WA doses favored an increase in pH and the availability of P, Ca, Mg, Na, K, Cu, and Zn in soil and N, P, and K absorption in ryegrass. WA favored the availability and later absorption of heavy metal(oid)s by ryegrass (staying mainly in the roots). Heavy metal(oid)s mobility in the soil-plant-water system was as follows: Cr > Pb > Ni > As.
Short Chain Fatty Acid Production from Mycoprotein and Mycoprotein Fibre in an In Vitro Fermentation Model

Dietary mycoprotein (marketed as QuornTM) has many health benefits, including reductions in energy intake. The majority of studies evaluating mycoprotein focus on the protein content and very few consider the fibre content. Fibre consumption is also associated with decreased energy intake, which is partly attributed to short chain fatty acids (SCFAs) from fibre fermentation by colonic bacteria. To study the SCFA-producing capability of mycoprotein, in vitro batch fermentations were conducted, and SCFA production compared with that from extracted mycoprotein fibre, oligofructose (OF), rhamnose, and laminarin. Mycoprotein and mycoprotein fibre were both fermentable, resulting in a total SCFA production of 24.9 (1.7) and 61.2 (15.7) mmol/L, respectively. OF led to a significantly higher proportion of acetate compared to all other substrates tested (92.6 (2.8)%, p < 0.01). Rhamnose generated the highest proportion of propionate (45.3 (2.0)%, p < 0.01), although mycoprotein and mycoprotein fibre yielded a higher proportion of propionate compared with OF and laminarin. Butyrate proportion was the highest with laminarin (28.0 (10.0)% although mycoprotein fibre led to a significantly higher proportion than OF (p < 0.01). Mycoprotein is a valuable source of dietary protein, but its fibre content is also of interest. Further evaluation of the potential roles of the fibre content of mycoprotein is required.
Pregnancy outcomes in patients with multiple sclerosis treated with teriflunomide: Clinical study data and 5 years of post-marketing experience

Background: Teriflunomide is contraindicated in pregnancy. Some pregnancies have occurred despite guidance to use effective contraception. Objectives: To report outcomes of pregnancies occurring in teriflunomide clinical trials and the post-marketing setting. Methods: Outcomes are summarized for pregnancies in teriflunomide monotherapy clinical trials and the post-marketing setting (data cutoff: December 2017). Results: Of 437 confirmed teriflunomide-exposed pregnancies, 222 had known outcomes (70 from clinical trials; 152 from the post-marketing setting); 161 were reported prospectively and 61 retrospectively. There were 107 (48.2%) live births, 63 (28.4%) elective abortions, 47 (21.2%) spontaneous abortions, 3 (1.4%) ectopic pregnancies, 1 (0.5%) stillbirth, and 1 (0.5%) maternal death leading to fetal death. Four birth defects were reported among cases with known pregnancy outcome: ureteropyeloectasia (only defect considered major); congenital hydrocephalus; ventricular septal defect; and malformation of right foot valgus. A case of cystic hygroma was identified on antenatal ultrasound (pregnancy outcome unknown). One elective abortion followed prenatal diagnosis of fetal anomaly (blighted ovum). The risk of major birth defects in prospectively reported live birth/stillbirth outcomes was 3.6% (1/28) in clinical trials and 0.0% (0/51) in post-marketing reports. Conclusions: Outcomes were consistent with the general population. Current human data do not indicate a teratogenic signal in teriflunomide-exposed pregnancies.
Oxidative Stress in Retinal Degeneration Promoted by Constant LED Light

Light pollution by artificial light, might accelerate retinal diseases and circadian asynchrony. The excess of light exposure is a growing problem in societies, so studies on the consequences of long-term exposure to low levels of light are needed to determine the effects on vision. The possibility to understand the molecular mechanisms of light damage will contribute to the knowledge about visual disorders related to defects in the phototransduction. Several animal models have been used to study retinal degeneration (RD) by light; however, some important aspects remain to be established. Previously, we demonstrated that cool white treatment of 200 lux light-emitting diode (LED) induces retinal transformation with rods and cones cell death and significant changes in opsin expression in the inner nuclear layer (INL) and ganglion cell layer (GCL). Therefore, to further develop describing the molecular pathways of RD, we have examined here the oxidative stress and the fatty acid composition in rat retinas maintained at constant light. We demonstrated the existence of oxidative reactions after 5 days in outer nuclear layer (ONL), corresponding to classical photoreceptors; catalase (CAT) enzyme activity did not show significant differences in all times studied and the fatty acid study showed that docosahexaenoic acid decreased after 4 days. Remarkably, the docosahexaenoic acid diminution showed a correlation with the rise in stearic acid indicating a possible association between them. We assumed that the reduction in docosahexaenoic acid may be affected by the oxidative stress in photoreceptors outer segment which in turn affects the stearic acid composition with consequences in the membrane properties. All these miss-regulation affects the photoreceptor survival through unknown mechanisms involved. We consider that oxidative stress might be one of the pathways implicated in RD promoted by light.
Polar gigantism and the oxygen–temperature hypothesis: a test of upper thermal limits to body size in Antarctic pycnogonids

The extreme and constant cold of the Southern Ocean has led to many unusual features of the Antarctic fauna. One of these, polar gigantism, is thought to have arisen from a combination of cold-driven low metabolic rates and high oxygen availability in the polar oceans (the ‘oxygen–temperature hypothesis'). If the oxygen–temperature hypothesis indeed underlies polar gigantism, then polar giants may be particularly susceptible to warming temperatures. We tested the effects of temperature on performance using two genera of giant Antarctic sea spiders (Pycnogonida), Colossendeis and Ammothea, across a range of body sizes. We tested performance at four temperatures spanning ambient (−1.8°C) to 9°C. Individuals from both genera were highly sensitive to elevated temperature, but we found no evidence that large-bodied pycnogonids were more affected by elevated temperatures than small individuals; thus, these results do not support the predictions of the oxygen–temperature hypothesis. When we compared two species, Colossendeis megalonyx and Ammothea glacialis, C. megalonyx maintained performance at considerably higher temperatures. Analysis of the cuticle showed that as body size increases, porosity increases as well, especially in C. megalonyx, which may compensate for the increasing metabolic demand and longer diffusion distances of larger animals by facilitating diffusive oxygen supply.
MicroRNA and their target mRNAs change expression in whole blood of patients after intracerebral hemorrhage

Previous studies showed changes in mRNA levels in whole blood of rats and humans, and in miRNA in whole blood of rats following intracerebral hemorrhage (ICH). Thus, this study assessed miRNA and their putative mRNA targets in whole blood of humans following ICH. Whole transcriptome profiling identified altered miRNA and mRNA levels in ICH patients compared to matched controls. Target mRNAs of the differentially expressed miRNAs were identified, and functional analysis of the miRNA-mRNA targets was performed. Twenty-nine miRNAs (22 down, 7 up) and 250 target mRNAs (136 up, 114 down), and 7 small nucleolar RNA changed expression after ICH compared to controls (FDR < 0.05, and fold change ≥ |1.2|). These included Let7i, miR-146a-5p, miR210-5p, miR-93-5p, miR-221, miR-874, miR-17-3p, miR-378a-5p, miR-532-5p, mir-4707, miR-4450, mir-1183, Let-7d-3p, miR-3937, miR-4288, miR-4741, miR-92a-1-3p, miR-4514, mir-4658, mir-3689d-1, miR-4760-3p, and mir-3183. Pathway analysis showed regulated miRNAs/mRNAs were associated with toll-like receptor, natural killer cell, focal adhesion, TGF-β, phagosome, JAK-STAT, cytokine–cytokine receptor, chemokine, apoptosis, vascular smooth muscle, and RNA degradation signaling. Many of these pathways have been implicated in ICH. The differentially expressed miRNA and their putative mRNA targets and associated pathways may provide diagnostic biomarkers as well as point to therapeutic targets for ICH treatments in humans.
Antibacterial Effectiveness of Gading Kuning Coconut Extract (Cocos nucifera var. Eburnea) in Aeromonas hydrophila Bacteria In Vitro

Fish disease caused by Aeromonas hydrophila bacteria is very dangerous. These bacteria spread very quickly and result in a decrease in growth rates and can kill fish. To overcome this problem, fish cultivators usually use chemical drugs or antibiotics. However, the use of antibiotics can cause bacterial resistance and the presence of antibiotic residues in fish which can be harmful if the fish is consumed, so it is necessary to do other alternatives using traditional medicine. Yellow ivory coconut husk (Cocos nucifera var. Eburnea) is believed to have antibacterial properties. However, the content of potential secondary metabolites in these plants is not known, therefore this study aimed to determine the ability of the extract of the yellow ivory coconut husk (Cocos nucifera var. Eburnea) in inhibiting the growth of Aeromonas hydrophila bacteria. This study used a completely randomized design (CRD) with 6 treatments and 4 repetitions. The method used in this study is the disc diffusion method. The results of the disc diffusion method showed that the extract of ivory yellow coconut coir (Cocos nucifera var. Eburnea) was able to inhibit the growth of Aeromonas hydrophila bacteria. The concentration of coco coir extract of yellow ivory (Cocos nucifera var. Eburnea) 5000 ppm had the highest inhibition zone value with an average of 12.225 mm. Statistical test results show the value of Asymp. Sig of 0.004 which means <0.05. This indicates that the extract of the yellow ivory coconut husk (Cocos nucifera var. Eburnea) is able to inhibit the growth of Aeromonas hydrophila bacteria
Direct Observation of Raman Spectra in Black Phosphorus under Uniaxial Strain Conditions

In this paper, we systematically studied the Raman vibration of black phosphorus (BP) transferred onto a germanium (Ge)-coated polydimethylsiloxane (PDMS) substrate, which generates a much higher contrast in BP. This engineered flexible substrate allowed us to directly observe a much thinner BP layer on the flexible substrate at the desired location. Therefore, it enabled us to perform Raman spectroscopy immediately after exfoliation. The Raman spectra obtained from several BP layers with different thicknesses revealed that the clear peak shifting rates for the Ag1, B2g, and Ag2 modes were 0.15, 0.11, and 0.11 cm−1/nm, respectively. Using this value to identify a 2–3-layered BP, a study on the strain–Raman spectrum relationship was conducted, with a maximum uniaxial strain of 0.89%. The peak shifting of Ag1, B2g, and Ag2 caused by this uniaxial strain were measured to be 0.86, 0.63, and 0.21 cm−1/Δε, respectively.
Immunometabolism of Phagocytes and Relationships to Cardiac Repair

Cardiovascular disease remains the leading cause of death worldwide. Myocardial ischemia is a major contributor to cardiovascular morbidity and mortality. In the case of acute myocardial infarction, subsequent cardiac repair relies upon the acute, and coordinated response to injury by innate myeloid phagocytes. This includes neutrophils, monocytes, macrophage subsets, and immature dendritic cells. Phagocytes function to remove necrotic cardiomyocytes, apoptotic inflammatory cells, and to remodel extracellular matrix. These innate immune cells also secrete cytokines and growth factors that promote tissue replacement through fibrosis and angiogenesis. Within the injured myocardium, macrophages polarize from pro-inflammatory to inflammation-resolving phenotypes. At the core of this functional plasticity is cellular metabolism, which has gained an appreciation for its integration with phagocyte function and remodeling of the transcriptional and epigenetic landscape. Immunometabolic rewiring is particularly relevant after ischemia and clinical reperfusion given the rapidly changing oxygen and metabolic milieu. Hypoxia reduces mitochondrial oxidative phosphorylation and leads to increased reliance on glycolysis, which can support biosynthesis of pro-inflammatory cytokines. Reoxygenation is permissive for shifts back to mitochondrial metabolism and fatty acid oxidation and this is ultimately linked to pro-reparative macrophage polarization. Improved understanding of mechanisms that regulate metabolic adaptations holds the potential to identify new metabolite targets and strategies to reduce cardiac damage through nutrient signaling.
Chronic hepatitis B virus infection and total and cause-specific mortality: a prospective cohort study of 0.5 million people

Objectives Chronic hepatitis B virus (HBV) infection is associated with a higher risk of liver diseases. Substantial uncertainty remains, however, about the associations of HBV infection with mortality from extrahepatic causes, especially from subtypes of cardiovascular diseases. We prospectively examined the association of chronic HBV infection with total and cause-specific mortality. Design Population-based prospective cohort study. Setting China Kadoorie Biobank in which participants from 10 geographically diverse areas across China were enrolled between 2004 and 2008. Participants 475 801 participants 30–79 years of age without reporting major chronic diseases at baseline were enrolled. Hepatitis B surface antigen (HBsAg) was tested using an on-site rapid test strip at baseline. Primary and secondary outcome measures Total and cause-specific mortality. Results A total of 35 822 deaths were recorded during ~10 years of follow-up. In multivariable-adjusted analyses, compared with HBsAg-negative participants, HBsAg-positive participants had an increased risk of total mortality (HR=2.01, 95% CI: 1.91 to 2.12), which was higher in men (HR=2.16, 95% CI: 2.01 to 2.31) than in women (HR=1.74, 95% CI: 1.60 to 1.90). Presence of HBsAg was associated with increased mortality from liver cancer (1339 deaths, HR=13.95, 95% CI: 12.46 to 15.62), infections (410 deaths, HR=10.30, 95% CI: 8.21 to 12.94), digestive diseases (688 deaths, HR=6.83, 95% CI: 5.49 to 8.50), intracerebral haemorrhage (4077 deaths, HR=1.38, 95% CI: 1.14 to 1.68) and ischaemic heart diseases (4624 deaths, HR=1.31, 95% CI: 1.09 to 1.58). The positive association between HBsAg status and risk of death was stronger in participants younger than 50 years, smokers, physically active or non-hypertensive participants. Conclusions Among Chinese adults, chronic HBV infection was associated with increased mortality from a range of hepatic and extrahepatic diseases.
The pro-death role of Cited2 in stroke is regulated by E2F1/4 transcription factors

We previously reported that the cell cycle–related cyclin-dependent kinase 4–retinoblastoma (RB) transcriptional corepressor pathway is essential for stroke-induced cell death both in vitro and in vivo. However, how this signaling pathway induces cell death is unclear. Previously, we found that the cyclin-dependent kinase 4 pathway activates the pro-apoptotic transcriptional co-regulator Cited2 in vitro after DNA damage. In the present study, we report that Cited2 protein expression is also dramatically increased following stroke/ischemic insult. Critically, utilizing conditional knockout mice, we show that Cited2 is required for neuronal cell death, both in culture and in mice after ischemic insult. Importantly, determining the mechanism by which Cited2 levels are regulated, we found that E2F transcription factor (E2F) family members participate in Cited2 regulation. First, E2F1 expression induced Cited2 transcription, and E2F1 deficiency reduced Cited2 expression. Moreover, determining the potential E2F-binding regions on the Cited2 gene regulatory sequence by ChIP analysis, we provide evidence that E2F1/4 proteins bind to this DNA region. A luciferase reporter assay to probe the functional outcomes of this interaction revealed that E2F1 activates and E2F4 inhibits Cited2 transcription. Moreover, we identified the functional binding motif for E2F1 in the Cited2 gene promoter by demonstrating that mutation of this site dramatically reduces E2F1-mediated Cited2 transcription. Finally, E2F1 and E2F4 regulated Cited2 expression in neurons after stroke-related insults. Taken together, these results indicate that the E2F–Cited2 regulatory pathway is critically involved in stroke injury.
Functional effects of botulinum toxin type A in the hip adductors and subsequent stretching in patients with hereditary spastic paraplegia.

OBJECTIVE To investigate the functional effects of bilateral botulinum toxin A treatment and subsequent stretching of spastic hip adductors on gait and reactive lateral stepping responses in patients with pure hereditary spastic paraplegia. DESIGN Explorative pre-post intervention study. PATIENTS Twenty-five patients with pure hereditary spastic paraplegia. METHODS Patients were treated with bilateral botulinum toxin A injections in the hip adductors and performed daily self-administered stretching exercises for 16 weeks. Before the intervention (T0), and 6 (T1) and 16 (T2) weeks thereafter, gait width, gait speed, and leg angles at first stepping-foot contact after lateral balance perturbations were assessed, as well as the corresponding success rates of reactive lateral steps. RESULTS Compared with baseline, gait width increased by 12.6% and 9.7% and comfortable gait speed by 8.3% and 11.5% at T1 and T2, respectively. In known perturbation directions, leg angles increased by 5.9% at T1 and 8.0% at T2, while success rates increased from 70% at baseline to 90% at T1 and T2. No effects were found for maximal gait speed or lateral stepping responses in unknown perturbation directions. CONCLUSION Bilateral botulinum toxin A treatment and subsequent stretching of the hip adductors may improve gait and reactive lateral stepping in patients with pure hereditary spastic paraplegia.
Substrate-Assisted Visualization of Surfactant Micelles via Transmission Electron Microscopy

The visualization of the micellar morphological evolution for surfactant has drawn much attention due to its self-assemble ability to fold into various structures. However, the direct observation of the soft materials with low atomic number has been hampered because of the poor scattering contrast and complex staining process by the traditional transmission electron microscopy (TEM) techniques. Herein, we reported a novel strategy to the visualization of surfactant micelles with the assistance of layered double hydroxides (LDHs) via TEM. Owing to the uniformly distributed metal ions and positive charges in the LDHs, the surfactant at the micelle-water interface reacted with LDHs to form a stabilized architecture through electrostatic and hydrogen-bond interactions. The morphologies of the surfactant can be clearly observed through the surfactant-LDHs architectures, exhibiting high contrast by TEM techniques. Significantly, the micellar evolutions involving the spherical, rodlike, and wormlike shapes were successfully distinguished. Our results may provide great possibilities and inspirations for the visualization for morphology of soft matters.
Hyponatremia Following a Marathon, A Multifactorial Case with over Infusion of Fluids.

Introduction Exercise-associated hyponatremia (EAH) describes a condition of hyponatremia occurring during or up to 24 h after physical activity (1). It is mostly associated with the combination of long-duration endurance exercise (94 h) and overhydration of hypotonic fluids (2). Some of the initial symptoms of EHA may be similar to other exertionalrelated symptoms, such as heat injuries and dehydration. This fact might lead to misdiagnosis and delayed or inappropriate medical treatment (3,4). This case report describes multifactorial etiologies that causes EAH and highlights the danger of misdiagnosis of EAH and mostly the caution that should be paid to the amount of fluids infused to athletes who collapse during or following long-endurance athletic events. The patient described in the following case report gave her formal consent to use her clinical data for presentation.
Synergistic Association of House Endotoxin Exposure and Ambient Air Pollution with Asthma Outcomes.

RATIONALE House endotoxin and ambient air pollution are risk factors for asthma; however, the effects of their co-exposure on asthma are not well characterized. OBJECTIVES To examine potential synergistic associations of co-exposure to house dust endotoxin and ambient air pollutants with asthma outcomes. METHODS We analyzed data from 6,488 participants in National Health and Nutrition Examination Survey (NHANES) 2005-2006. Dust from bedding and bedroom floor was analyzed for endotoxin content. The Community Multiscale Air Quality (CMAQ) and Downscaler (DS) data were used to determine annual average particulate matter ≤2.5 μm (PM2.5), ozone (O3), and nitrogen dioxide (NO2) exposures at participants' residential locations. The associations of the co-exposures with asthma outcomes were assessed and tested for synergistic interaction. RESULTS In adjusted analysis, PM2.5 (CMAQ) (OR 1.12, 95% CI: 1.07-1.18), O3 (DS) (OR 1.07, 95% CI: 1.02-1.13), and log1010-NO2 (CMAQ) (OR 3.15, 95% CI: 1.33-7.45) were positively associated with emergency room (ER) visits for asthma in the past 12 months. Co-exposure to elevated levels of house dust endotoxin and PM2.5 (CMAQ) was synergistically associated with the outcome, increasing the odds by 5-fold (OR 5.01, 95% CI: 2.54-9.87). A synergistic association was also found for co-exposure to higher concentrations of endotoxin and NO2 in children (OR 3.45, 95% CI: 1.65-7.18). CONCLUSIONS Co-exposure to elevated levels of residential endotoxin and ambient PM2.5 in all participants and NO2 in children is synergistically associated with increased ER visits for asthma. Therefore, decreasing exposure to both endotoxin and air pollution may help reduce asthma morbidity.
