The efficacy observation of two pesticides impregnated bednets for pest control in field in Sudan

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Objective To observe the residual effects of Fendona and Demand impregnated bednets for pest control in peacekeeping area in Sudan. Methods Fendona (30 mg·ai/m2) and Demand (20 mg·ai/m2) was used to impregnate bednets before going abroad. Observating the dead number of mosquitoes, flies and other insects on the bednets one time every three days. Results The bednets impregnated by Demand has good residual effect for mosquitoes, flies and other insects after 27 days. The residual effect of bednets impregnated by Fendona appeared obviously decline after 21 days. Compared the dead number of vector on bednets impregnated by Demand and Fendona, there was significant difference in statistics on 21 days on mosquitoes (Z=2.373, P=0.015) and on 24 days on flies and other vector (Z=1.783,P=0.047;Z=2.096,P=0.026,each). Conclusion Bednets treated by two pesticides are efficient for vector control, but Demand at 20 mg·ai/m2 is better than Fendona at 30 mg·ai/m2 because Demand can last more residual effects time.
Embryonic Molar Pregnancy: A Rare Case Report

Field: Medicine (Health Sciences)

Partial hydatiform mole (MHP) represents a spectrum of trophoblastic-related disorders occurring during pregnancy. Also known as embryonal mole, it is characterized by a recognizable ovum abnormality with vesicular transformation of villi but with recognizable placental appearance and amniotic cavity containing the fetus. First-trimester spontaneous abortion most commonly suggests the diagnosis. Partial moles rarely persist beyond the first trimester and are then a cause of maternal and fetal complications and diagnostic confusion. MHP of genetic origin is triploi d with extra chromosome of paternal origin. The coexistence of normal fetal karyotype and MHP is exceptional. We report a rare case of partial molar pregnancy with liveborn diploid fetus in a 30-year-old woman diagnosed with threat of premature labour associated with placenta previa at 11 weeks of amenorrhea (WA).
Time Petri net with discrete time span

Field: Computer Science (Physical Sciences)

In the modeling of real system by using Petri net,the implementation of event must be in a series time span sometimes.To deal with this problem,a Discrete Time Span Petri Net(DTSPN) based on time Petri net was proposed.Model's attainability was analyzed with great emphasis,and the algorithm of distinguishing model's valid transaction sequence was given.On this basis,a new algorithm about state attainability aimed at DTSPN was proposed.By the analysis of example,the proposed DTSPN model was feasible and valid.It could be applied in workflow analysis and business process modeling,and the simulated and analyzing capability of Petri net could also be improved.

Insights into the Mechanisms of Lactobacillus acidophilus Activity against Entamoeba histolytica by Using Thiol Redox Proteomics

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Amebiasis is an intestinal disease transmitted by the protist parasite, Entamoeba histolytica. Lactobacillus acidophilus is a common inhabitant of healthy human gut and a probiotic that has antimicrobial properties against a number of pathogenic bacteria, fungi, and parasites. The aim of this study was to investigate the amebicide activity of L. acidophilus and its mechanisms. For this purpose, E. histolytica and L. acidophilus were co-incubated and the parasite’s viability was determined by eosin dye exclusion. The level of ozidized proteins (OXs) in the parasite was determined by resin-assisted capture RAC (OX–RAC). Incubation with L. acidophilus for two hours reduced the viability of E. histolytica trophozoites by 50%. As a result of the interaction with catalase, an enzyme that degrades hydrogen peroxide (H2O2) to water and oxygen, this amebicide activity is lost, indicating that it is mediated by H2O2 produced by L. acidophilus. Redox proteomics shows that L. acidophilus triggers the oxidation of many essential amebic enzymes such as pyruvate: ferredoxin oxidoreductase, the lectin Gal/GalNAc, and cysteine proteases (CPs). Further, trophozoites of E. histolytica incubated with L. acidophilus show reduced binding to mammalian cells. These results support L. acidophilus as a prophylactic candidate against amebiasis.
Nuclear Level Density with Non-zero Angular Momentum

Field: Physics and Astronomy (Physical Sciences)

The statistical properties of interacting fermions have been studied for various angular momentum with the inclusion of pairing interaction. The dependence of the critical temperature on angular momentum for several nuclei, have been studied. The yrast energy as a function of angular momentum for (28)Si and (24)Mg nuclei have been calculated up to 60.0 MeV of excitation energy. The computed limiting angular momenta are compared with the experimental results for (26)Al produced by (12)C+(14)N reaction. The relevant nuclear level densities for non-zero angular momentum have been computed for (44)Ti and (136)Ba nuclei. The results are compared with their corresponding values obtained from the approximate. formulas.
Characterization and Fate of Hydrogen-Bonded Free-Radical Intermediates and Their Coupling Products from the Hydrogen Atom Transfer Agent 1,8-Naphthalenediol

Field: Chemistry (Physical Sciences)

1,8-Naphthalenediol (dihydroxynaphthalene, 1,8-DHN) has been shown to be a potent hydrogen atom transfer (HAT) antioxidant compound because of the strong stabilization of the resulting free radical by intramolecular hydrogen bonding. However, the properties, reactivity, and fate of the 1,8-DHN phenoxyl radical have remained so far uncharted. Herein, we report an integrated experimental and computational characterization of the early intermediates and dimer products that arise by the oxidation of 1,8-DHN. Laser flash photolysis (LFP) studies of HAT from 1,8-DHN to the cumyloxyl and aminoxyl radicals showed the generation of a transient species absorbing at 350, 400, and >600 nm attributable to the 1,8-DHN phenoxyl radical. Peroxidase/H2O2 oxidation of 1,8-DHN was found to proceed via an intense blue intermediate (λmax 654 nm) preceding precipitation of a black melanin-like polymer. By halting the reaction in the early stages, three main dimers featuring 2,2'-, 2,4'-, and 4,4'-bondings could be isolated and characterized in pure form. Density functional theory calculations supported the generation of the 1,8-DHN phenoxyl radical and its subsequent coupling via the 2- and 4-positions giving extended quinone dimers with intense transitions in the visible range, consistent with UV-vis and LFP data. Overall, these results allowed to elucidate the mechanism of oxidative polymerization of 1,8-DHN of possible relevance to melanogenesis in fungi and other processes of environmental and astrochemical relevance.
RESEARCH ON THE WEAR FAILURE MECHANISM OF HIGH SPEED POSITIVE DISPLACEMENT MOTOR BEARINGS

Field: Engineering (Physical Sciences)

The bearing group is a key load-bearing structure of positive displacement motor (PDM), which experiences significant alternating heavy loads during the drilling process and causes failure accidents.In order to study the failure mechanism of the bearing group, the bearing group of the  165mm positive displacement motor was taken as the research object.Based on the structural characteristics of the drive shaft assembly and the point contact theory of the thrust ball bearing, the load of the thrust bearing was analyzed and calculated.A finite element model was established for the nonlinear contact problem between the steel ball, stator, and rotor, and numerical analysis was conducted for ball bearings with different degrees of wear.The research results indicate that: 1) it is easy to cause fatigue fracture of the inner and outer rings when the series bearing operates for a long time and under the special working conditions.In addition, the inner ring of the string bearing has problems such as unqualified surface roughness and local hardness, which exacerbates the damage of the string bearing.2) As the wear increases, the contact area between the bearing stator, rotor, and ball gradually decreases, and the stress concentration at the contact area between the steel ball and the stator and rotor intensifies, resulting in a significant increase in contact stress.3) The maximum Mises stress, contact force, and contact stress that bearings are subjected to are greatly affected by ball wear.Once the ball wears, the stress concentration phenomenon will lead to a rapid increase in the bearing capacity of the shaft, which will intensify with the increase of drilling pressure.4) Under the same working conditions, the maximum stress of the ball after wear of 1.5mm increased by 7.3 times compared to that without wear, resulting in bearing failure.The research methods and results of this article provide theoretical guidance for reducing the failure accidents of positive displacement motor bearing groups.
Laparoscopic TVT Sling Removal Following Prior Transvaginal Sling Excision

Field: Medicine (Health Sciences)

Several studies have reported the incidence and prevalence of retropubic tension-free vaginal mesh tape (TVT) slingrelated complications, but there are no specific current guidelines regarding the surgical management of such complications.Complications requiring sling removal, such as pain, can be surgically managed by using either a vaginal approach, removing the vaginal portion of the sling up to the pubocervical fascia, and/or a laparoscopic/abdominal approach to the space of Retzius to remove the retropubic portion of the sling.We report a case of a patient with a retropubic TVT sling in whom the removal of the vaginal portion of the sling failed to resolve the patient's symptoms of pain; therefore, a laparoscopic approach to the retropubic space was performed to extract the remaining limbs of the sling.

[Expanding intramedullary rods in the treatment of osteogenesis imperfecta (author's transl)].

Field: Medicine (Health Sciences)

Eleven cases of osteogenesis imperfecta were treated by corrective osteotomies and fixation with expanding intramedullary rods. The authors have used the Bailey-Dubow nail. Despite a short follow-up (average one year) they think that the device will avoid future repeated changes of rods during the growing period. Several technical pitfalls are described. It is thought that the same technique could be applied to congenital pseudarthrosis of the tibia.

Genotype x environment interaction for seed yield and related traits in french bean (Phaseolus vulgaris L.)

Field: Agricultural and Biological Sciences (Life Sciences)

Twenty five genotypes of French bean were evaluated at three different locations of Punjab viz., PAU Ludhiana; USF, Usman, Tarn Taran, and KVK, Kheri, Sangrur during spring seasons of 2017 and 2018. The mean squares for genotypes were highly significant for all the characters under study. Highly significant mean squares for environments and genotype x environment interaction were recorded for all the characters. The linear component of genotype x environment interaction was also significant for all the traits. The highest green pod yield was recorded in genotype Arka Suvidha followed by Arka Anoop, Falguni, Arka Sharath and FB-3-16 which produced significantly higher green pod yield than check Contender. The genotypes Arka Suvidha, Arka Anoop, Arka Sharath and Contender responded better under favorable environments, while genotype FBK-2 was better under unfavorable environments for seed yield per plant.
Efficacy of Porcine Circovirus Type 2a and 2d Based Vaccines Following PCV2 Challenge

Field: Veterinary (Health Sciences)

This study evaluated the efficacy of PCV2a and PCV2d vaccines against a PCV2 challenge. Three-week-old, cesarean-derived, colostrum-deprived pigs were blocked by litter and randomized to treatment group. Pigs received a single 2 mL intramuscular dose of either placebo (PLAC, n=50), PCV2a vaccine (PCV2aV, n=25), or PCV2d vaccine (PCV2dV, n=25) on D0 and were challenged with a PCV2d isolate on D28. Prior to challenge, a naturally occurring PCV2a infection was identified. Both vaccines similarly prevented lymphoid tissue lesions, mortality and clinical signs of PCVAD while PLAC pigs were severely affected. Viremia was significantly reduced 7, 14, 21, and 28 days post-challenge and average daily weight gain was significantly increased for both vaccine groups. The prevention of mortality and very minimal occurrence of lymphoid tissue lesions in both vaccine groups, provides clear evidence of the benefit of PCV2 vaccination in the face of a virulent mixed PCV2 challenge.
Retrospective, observational data collection of the treatment of phenylketonuria in the UK, and associated clinical and health outcomes

Field: Medicine (Health Sciences)

The results support current literature showing that a proportion of subjects with PKU, in particular older subjects, are not fully compliant with their treatment and subsequently have Phe concentrations that depart from national recommendations. However, definitive conclusions may not be drawn due to the retrospective nature of the study and the small number of observed subjects.
Bombardment of CO ice by cosmic rays: I. Experimental insights into the microphysics of molecule destruction and sputtering

Field: Physics and Astronomy (Physical Sciences)

We present a dedicated experimental study of microscopic mechanisms controlling radiolysis and sputtering of astrophysical ices due to their bombardment by cosmic ray ions. Such ions are slowed down due to inelastic collisions with bound electrons, resulting in ionization and excitation of ice molecules. In experiments on CO ice irradiation, we show that the relative contribution of these two mechanisms of energy loss to molecule destruction and sputtering can be probed by selecting ion energies near the peak of the electronic stopping power. We have observed a significant asymmetry, both in the destruction cross section and the sputtering yield, for pairs of ion energies corresponding to same values of the stopping power on either side of the peak. This implies that the stopping power does not solely control these processes, as usually assumed in the literature. Our results suggest that electronic excitations represent a significantly more efficient channel for radiolysis and, possibly, also for sputtering of CO ice. We also show that the charge state of incident ions as well as the rate for CO$^+$ production in the ice have negligible effect on these processes.
Uncertainty matters: ascertaining where specimens in natural history collections come from and its implications for predicting species distributions

Field: Environmental Science (Physical Sciences)

Natural history collections (NHCs) represent an enormous and largely untapped wealth of information on the Earth's biota, made available through GBIF as digital preserved specimen records. Precise knowledge of where the specimens were collected is paramount to rigorous ecological studies, especially in the field of species distribution modelling. Here, we present a first comprehensive analysis of georeferencing quality for all preserved specimen records served by GBIF, and illustrate the impact that coordinate uncertainty may have on predicted potential distributions. We used all GBIF preserved specimen records to analyse the availability of coordinates and associated spatial uncertainty across geography, spatial resolution, taxonomy, publishing institutions and collection time. We used three plant species across their native ranges in different parts of the world to show the impact of uncertainty on predicted potential distributions. We found that 38% of the 180+ million records provide coordinates only and 18% coordinates and uncertainty. Georeferencing quality is determined more by country of collection and publishing than by taxonomic group. Distinct georeferencing practices are more determinant than implicit characteristics and georeferencing difficulty of specimens. Availability and quality of records contrasts across world regions. Uncertainty values are not normally distributed but peak at very distinct values, which can be traced back to specific regions of the world. Uncertainty leads to a wide spectrum of range sizes when modelling species distributions, potentially affecting conclusions in biogeographical and climate change studies. In summary, the digitised fraction of the world's NHCs are far from optimal in terms of georeferencing and quality mainly depends on where the collections are hosted. A collective effort between communities around NHC institutions, ecological research and data infrastructure is needed to bring the data on a par with its importance and relevance for ecological research.
