Catheter ablation of atrial tachycardia via extracardiac access
Authors: Shalganov Tchavdar , Stoyanov Milko 
Published: June 2020

A female patient with nonautomatic focal atrial tachycardia with paraHissian location of the focus and previously unsuccessful ablation attempt in the right atrium (RA) is presented. Electroanatomic mapping demonstrated sequential activation of the anteroseptal area of the RA, anteroseptal area of the left atrium and non-coronary sinus of Valsalva with minimal differences in local activation times. Because of perceived risk of conduction disturbances ablation was done in the non-coronary sinus with immediate termination of the tachycardia, subsequent non-inducibility and without any complications.

Introduction. Interventional cardiac procedures are often associated with high patient exposure and therefore require special care in protecting patients from radiation-induced effects.
Materials and methods. A retrospective study of typical patients’doses was performed in nine hospitals, with a total number of fourteen angiography systems. The typical values for kerma-area product (KAP), cumulative dose (CD) and fluoroscopy time (FT) for two of the most commonly performed procedures - percutaneous coronary intervention (PCI) and coronary arteriography (CA), were calculated and compared with the Bulgarian National Diagnostic Reference Levels (NDRL). Data analysis, regarding the risk of radiation-induced skin effects due to interventional cardiac procedures, was performed.
Aim. 1) to present and analyze the typical KAP values for PCI and CA procedures in cardiology departments with high workload and to compare them with the NDRL; 2) to compare the patient doses with the follow-up levels published in Ordinance 2, to identify patients at risk for radiation-induced effects.
Results. The results show that typical values for PCI and CA procedures for some of the angiography systems are higher than the NDRL. In all investigated departments there are patients with at least one exceeded follow-up level for PCI.
Conclusions. The results show a potential for optimization in the departments with both high or very low typical dose or FT values. No radiation-induced effect was observed in the followed-up group of patients. The introduction of procedure with "Instruction to the patient after an interventional cardiac procedure(s) with greater complexity and a long fluoroscopy time" for patient follow-up and its regular implementation into the routine clinical practice will help for timely diagnosis and treatment of radiation-induced skin effects after cardiac procedures under fluoroscopy control.
Nutritional developmental history and its consequences for reproductive success in Drosophila suzukii (Diptera: Drosophilidae)
Authors: Young Yvonne , Long Tristan A.F. 
Published: June 2020

AbstractThe characteristics of the juvenile developmental environment of an individual can have many important consequences for their adult reproductive success as it may shape the development and expression of phenotypes that are relevant to the later operation of sexual selection. Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is an economically important invasive pest species that lays its eggs in many types of soft fruits and potentially experiences large intrapopulation spatial and temporal variation in its nutritional developmental environments. Here, we examine whether the larval nutritional developmental environment influences D. suzukii mate choice, egg production, and offspring performance. Using D. suzukii raised on diets differing in their nutritional quality, we examined mating preferences, fecundity, and offspring survivorship in “no-choice,” “female choice,” and “male choice” reproductive contexts. We found evidence for both adaptive and nonadaptive mate choice behaviours associated with the phenotypes of D. suzukii that had developed in different nutritional environments. These results reveal the complex nature of the relationship between the developmental environment and individual reproductive success in D. suzukii, which has important potential implications for future management plans involving this species.

Abstract
Recent studies indicate that glucose metabolism is altered in rheumatoid arthritis. We hypothesize that Pkm2, as a key regulatory enzyme of glycolysis pathway, triggers the activation of macrophages (Mφ), which results in proinflammatory cytokine production during the arthritis progress. In this study, Pkm2 was found to be overexpressed in ED1-positive Mφ in spleens and synovial tissues from arthritic rats via immunofluorescence, Western blotting, and quantitative RT-PCR. To reveal the role of Pkm2, Dark Agouti rats were treated with either Pkm2 enzyme inhibitor shikonin or the RNA interference plasmids of Pkm2 and negative control plasmids, respectively, via i.p. injection. Pkm2 intervention could alleviate the severity of pristane-induced arthritis in aspects of the macroscopic arthritis score, perimeter changes of midpaw, and the synovitis and destruction of the bone and cartilage as well as reduce the ED1 and p-Stat1–positive cell population in rat synovial tissues. Silencing Pkm2 by RNA interference in classical activated rat and mouse Mφ resulted in less Tnf-α, Il-1β production via Stat1 signaling. Collectively, Pkm2 is highly expressed in ED1-positive Mφ of spleens and synovial tissues from arthritic rats and promotes Mφ activation via Stat1 signaling. Pkm2 might be a promising selective metabolic target molecule for rheumatoid arthritis treatment.

Published: June 2020

Abstract. Measurements performed in western Africa (Senegal) during the SHADOW field
campaign are analyzed to show that spectral dependence of the imaginary part
of the complex refractive index (CRI) of dust can be revealed by
lidar-measured particle parameters. Observations in April 2015 provide good
opportunity for such study, because, due to high optical depth of the dust,
exceeding 0.5, the extinction coefficient could be derived from lidar
measurements with high accuracy and the contribution of other aerosol types,
such as biomass burning, was negligible. For instance, in the second half of
April 2015, AERONET observations demonstrated a temporal decrease in the
imaginary part of the CRI at 440 nm from approximately 0.0045 to 0.0025. This
decrease is in line with a change in the relationship between the lidar
ratios (the extinction-to-backscattering ratio) at 355 and 532 nm
(S355 and S532). For instance in the first half of April,
S355∕S532 is as high as 1.5 and the backscatter Ångström exponent,
Aβ, is as low as −0.75, while after 15 April
S355/S532=1.0 and Aβ is close to zero. The aerosol
depolarization ratio δ532 for the whole of April exceeded 30 %
in the height range considered, implying that no other aerosol, except dust,
occurred. The performed modeling confirmed that the observed
S355∕S532 and Aβ values match the spectrally dependent
imaginary part of the refractive index as can be expected for mineral dust
containing iron oxides. The second phase of the SHADOW campaign was
focused on evaluation of the lidar ratio of smoke and estimates of its
dependence on relative humidity (RH). For five studied smoke episodes the
lidar ratio increases from 44±5 to 66±7 sr at 532 nm and
from 62±6 to 80±8 sr at 355 nm, when RH varied from 25 %
to 85 %. Performed numerical simulations demonstrate that observed ratio
S355∕S532, exceeding 1.0 in the smoke plumes, can indicate an
increase in the imaginary part of the smoke particles in the ultraviolet
(UV) range.

Procedure-Specific Hardware Removal After Evans Osteotomy
Authors: DeHeer Patrick A. , Patel Shrunjay , Standish Sarah N. 
Published: June 2020

Background
The Evans osteotomy is a widely used procedure for the correction of adult and pediatric flexible flatfoot deformity. Locking plates are commonly used to stabilize the osteotomy and the allograft. However, there have been incidences of soft-tissue irritation caused by the hardware, requiring subsequent hardware removal. Therefore, we sought to review whether age, sex, or laterality of the procedure had any correlation with the rate of hardware removal.

Methods
A retrospective review was performed of 47 consecutive patients who underwent an Evans calcaneal osteotomy between October 1, 2013, and October 1, 2016. Data were collected and analyzed based on age, sex, laterality, and the need for hardware removal.

Results
All of the 47 patients met the inclusion criteria. Seventy procedures were performed, and hardware removal was required in 16 patients and 21 feet (30%). The only statistically significant finding was that 11 females and only five males required either unilateral or bilateral hardware removal (P = .039). All 16 patients reported complete pain relief after hardware removal.

Conclusions
Females are twice as likely as males to develop symptoms after locking plate application over an Evans osteotomy and may require hardware removal. Despite the low-profile nature of the locking plate to fixate the Evans osteotomy, the hardware can be a source of significant pain. Patients, especially females, should be cautioned about potential hardware-related pain and a possible follow-up procedure to remove the hardware.
Development of Enzymatic Microtoxicity Test for the Toxicity Assay of Chlorophenolic Compounds
Authors: Ünal Arzu 
Published: June 2020

Enzymes are proteins that serve as catalysts of biological reactions in the animal, plant, and microbial cells. They are quite specific concerning with regard to their substrates. Enzymes lower the activation energy and increase the rate of biochemical reactions. According to the type of reaction catalyzed, enzymes are currently subdivided into six classes, namely oxidoreductases, hydrolases, transferases, lyases, isomerases, and ligases.
The effects of toxic chemicals and chlorophenolic compounds on enzyme activity are determined by fast, useful, and simple enzymatic methods. These methods can be carried out in low volumes and automatically using equipment such as a spectrophotometer, fluorometer and scintillation counters.
In this study, a new microtoxicity test was developed with the use of the fungal and bacterial β-galactosidase enzyme. In the toxicity experiments, the effects of 2,4,6-trichlorophenol (2,4,6 TCP), 2,4-dichlorophenol (2,4 DCP) and 4-chlorophenol (4 CP) over the β-galactosidase enzyme activity were investigated.
In this study, the bacterial and fungal β-galactosidase enzyme was found to be effective in determining the detoxification of some chlorinated phenolic compounds, 2,4,6-TCP, 2,4-DCP, and 4-CP, through the treatment with laccase enzyme. The inhibitor effect of toxic compounds on the activity of the β-galactosidase enzyme was examined. As a result of the studies, 61% inhibition for 2,4,6-TCP, 58% inhibition for 2,4-DCP and 47% inhibition for 4-CP was observed.
Mikrotoxicity test system developed in our laboratory which works principally based on inactivation of β-galactosidase activity by toxic chlorinated phenolics, was used for toxicity detection. Data obtained from microtoxicity tests have shown that the dechlorination of chlorinated phenolics with laccase has resulted in the loss of toxic potentiality of these chemicals to a substantial extent.
We thought that this study is to be an important contribution to bioremediation science and environmental technology with a new biotechnological approach.

Published: June 2020

Aims: To evaluate whether the initial growth and production of green biomass of the legume species Crotalaria juncea L. and Canavalia ensiformis (L.) DC. are influenced by phosphate fertilizer.
Study Design: A completely randomized design was used in a scheme 05 treatments x 02 cultures, with 3 replications, totaling 30 vessels in the experiment.
Place and Duration of Study: Forest nursery the Federal University of Campina Grande, campus of Patos-PB, between April 2018 and May 2018.
Methodology: The treatments consisted of two legumes (C. juncea and C. ensiformis) and five doses of phosphorus (00-50-100-150-200 mg kg-1 of P2O5) through single super phosphate. Fortnightly measurements of height and diameter were performed for 60 days. Fresh biomass of the shot and root was obtained at the end of the evaluations.
Results: There is a higher growth in height for individuals of C. ensiformis when cultivated in doses of 150 mg kg-1, with an average of 30.68 cm. For C. juncea, the treatments were similar. For the stem diameter, there was significant interaction (p <0.05) only for C. juncea, in which, unlike the results obtained for height, this variable grew linearly with increased phosphorus doses. Regardeless of the P doses fresh biomass production of C. ensiformis was higher than to C. juncea. Already in function on the levels of P there is an influence of nutrient only for C. ensiformis, with higher total biomass production and when cultivated with 100 mg kg-1 of P2O5.
Conclusion: Regardless of the cultivated species phosphorus influences the initial growth and production of fresh biomass. In general, it is recommended to cultivate the legumes studied with doses of 100 mg kg-1 of P2O5 through single super phosphate for a higher production of total fresh biomass.

Published: June 2020

Aims: The objective of this study was to evaluate the effects of nitrogen fertilizer application on the direct and indirect productive components of safflower.
Study Design: The treatments were arranged in randomized blocks, with four replicates, and consisted of five doses of nitrogen (N): 0, 50, 100, 150 and 200 kg.ha-1, in the form of urea (45% N), which was manually incorporated into the soil 30 days after plant emergence.
Place and Duration of Study: Sowing was carried out under field conditions on a small rural property in the municipality of Toledo-PR, Brazil. The experiment was conducted in between May and October 2018, totaling 158 days.
Methodology: Morphometric parameters were evaluated at the full flowering stage, and the yield and chemical composition of the achenes were assessed during physiological maturation of the plants. Data were analyzed using analysis of variance (ANOVA) at the 5% significance level. Regression equations were fitted to the means of the quantitative variables.
Results: The results showed that safflower grain yield was strongly influenced by the application of N-urea, with the maximum yield at a dose of 120 kg.ha-1 N. A joint analysis of the regression equation for N-urea application and grain yield, and the prices of N and safflower grains used, revealed that the most economical dose was 70 kg.ha-1 N, which provided the maximum profit per unit area. There was a positive linear correlation between grain yield and protein content (r = 0.51). Stem diameter, aerial dry biomass, grain yield, number of branches, and floral chapters per plant increased with N application, indicating that safflower culture responds positively to nitrogen fertilization.
Conclusion: We conclude that sustainable use of nitrogen fertilizer using the maximum economic efficiency dose, can contribute to better plant health and, at the same time, reduce production costs.
