Background
Severe pre-eclampsia-eclampsia is a type of hypertensive disorders in pregnancy associated with increased maternal and perinatal morbidity and mortality.
Methods
This was a retrospective study. The records of women admitted and managed with severe pre-eclampsia-eclampsia at the Federal Medical Centre Keffi from 1st January 2020 to 31st December 2022 were retrieved from the health information management unit, labour ward, post natal ward and theatre of the hospital. Relevant data such as; patients’ age, parity, education, booking status, gestational age at delivery, diagnosis, complications, mode of delivery, birth weight, Apgar scores, month of presentation and final outcome (alive or dead) were imputed into a proforma. The data were collated and analyzed using IBM SPSS 25. Descriptive and inferential statistics were computed for all data and results presented in simple tables and charts.
Results
There were 4,050 deliveries conducted of which 123 women had severe pre-eclampsia/eclampsia, resulting in a prevalence of 3.8%. Of these, 80 (65%) had severe pre-eclampsia and 43 (35%) had eclampsia. The mean age of the women was 29.88 ± 6.71 years and mean gestational age was 36 ± 3.483 weeks. There were 7 maternal deaths. giving a case fatality rate of 5.7%. The mean birth weight ± SD was 2.46 ± 0.860kg and stillborn rate was 26.8%. Severe pre-eclampsia/eclampsia was more common during the wet season.
Conclusions
The prevalence of pre-eclampsia/eclampsia was high in this study. with associated increased maternal and perinatal morbidity and mortality. Urgent interventions are required to address this significant health concern

Importance of vegetation for manganese cycling in temperate forested watersheds

Published: January 2015

AbstractMany surface soils are enriched in metals due to anthropogenic atmospheric inputs. To predict the persistence of these contaminants in soils, factors that impact rates of metal removal from soils into streams must be understood. Experiments at containerized seedling (mesocosm), pedon, and catchment scales were used to investigate the influence of vegetation on manganese (Mn) transport at the Susquehanna/Shale Hills Critical Zone Observatory (SSHCZO) in Pennsylvania, USA, where past atmospheric inputs from industrial sources have enriched Mn in surface soils. Large quantities of Mn that were leached from soil components into solution were taken up by vegetation; as a result, only relatively small quantities of Mn were removed from soil into effluent and streams. Manganese uptake into vegetation exceeded Mn losses in soil leachate by 20–200X at all scales, and net Mn loss from soils decreased in the presence of vegetation due to uptake into plant tissues. The majority of Mn taken up by forest vegetation at SSHCZO each year was returned to the soil in leaf litter and consequently immobilized as Mn oxides that formed during litter decomposition. Thus, plant uptake of Mn combined with rapid oxidation of Mn during litter decomposition contribute to long‐term retention. Current release rates of soluble Mn from SSHCZO soils were similar to release rates from the larger Susquehanna River Basin, indicating that the processes observed at SSHCZO may be widespread across the region. Indeed, although atmospheric deposition of Mn has declined, surface soils at SSHCZO and throughout the eastern United States remain enriched in Mn. If recycling through vegetation can attenuate the removal of Mn from soils, as observed in this study, then Mn concentrations in soils and river waters will likely decrease slowly over time following watershed contamination. Understanding the role of vegetation in regulating metal transport is important for evaluating the long‐term effects of historical and ongoing metal loading to soils.

Published: January 2015

AbstractIn an assessment of how Arctic sea ice cover could be remediated in a warming world, we simulated the injection of SO2 into the Arctic stratosphere making annual adjustments to injection rates. We treated one climate model realization as a surrogate “real world” with imperfect “observations” and no rerunning or reference to control simulations. SO2 injection rates were proposed using a novel model predictive control regime which incorporated a second simpler climate model to forecast “optimal” decision pathways. Commencing the simulation in 2018, Arctic sea ice cover was remediated by 2043 and maintained until solar geoengineering was terminated. We found quantifying climate side effects problematic because internal climate variability hampered detection of regional climate changes beyond the Arctic. Nevertheless, through decision maker learning and the accumulation of at least 10 years time series data exploited through an annual review cycle, uncertainties in observations and forcings were successfully managed.

Published: January 2015

ABSTRACTIn the Roman period, urban and rural ways of living were differentiated philosophically and legally, and this is the first regional study of these contrasting life‐ways. Focusing on frailty and mortality risk, we investigated how these differed by age, sex, and status, using coffin type as a proxy for social status. We employed skeletal data from 344 individuals: 150 rural and 194 urban (1st–5th centuries A.D.) from Dorset, England. Frailty and mortality risk were examined using indicators of stress (cribra orbitalia, porotic hyperostosis, nonspecific periostitis, and enamel hypoplastic defects), specific metabolic and infectious diseases (rickets, scurvy, and tuberculosis), and dental health (carious lesions and calculus). These variables were studied using Chi‐square, Siler model of mortality, Kaplan–Meier analysis, and the Gompertz model of adult mortality. Our study found that overall, mortality risk and survivorship did not differ between cemetery types but when the data were examined by age, mortality risk was only significantly higher for urban subadults. Demographic differences were found, with urban cemeteries having more 0–10 and >35 year olds, and for health, urban cemeteries had significantly higher frequencies of enamel hypoplastic defects, carious lesions, and rickets. Interestingly, no significant difference in status was observed between rural and urban cemeteries. The most significant finding was the influence of the skeletal and funerary data from the Poundbury sites, which had different demographic profiles, significantly higher frequencies of the indicators of stress and dental health variables. In conclusion, there are significant health, demographic, and mortality differences between rural and urban populations in Roman Britain.

Published: January 2015

AbstractPickering‐Emulsionen sind tensidfreie Dispersionen von zwei nicht mischbaren Flüssigkeiten, die durch Kolloidpartikel stabilisiert werden. Diese Systeme sind ökologisch besonders interessant, weil hiermit Reaktionen tensid‐ und lösungsmittelfrei durchgeführt werden können. Die kolloidstabilisierten Emulsionen unterscheiden sich in ihren Eigenschaften deutlich von tensidstabilisierten Emulsionen, Mikroemulsionen und micellaren Systemen. Trotz dieser spezifischen Vorteile sind die Anwendungsmöglichkeiten von Pickering‐Emulsionen noch wenig erforscht. In diesem Kurzaufsatz werden neue amphiphile Hybridmaterialien und Komposite für Grenzflächenkatalysatoren in Pickering‐Emulsionen beschrieben. Ein besonderer Fokus liegt dabei auf dem Einsatz in industrierelevanten Zweiphasenreaktionen zur Synthese von Feinchemikalien, Biokraftstoffveredelung und Dekontamination.
Biopsy Proven Medullary Sponge Kidney: Clinical Findings, Histopathology, and Role of Osteogenesis in Stone and Plaque Formation

Published: January 2015

ABSTRACTMedullary sponge kidney (MSK) is associated with recurrent stone formation, but the clinical phenotype is unclear because patients with other disorders may be incorrectly labeled MSK. We studied 12 patients with histologic findings pathognomonic of MSK. All patients had an endoscopically recognizable pattern of papillary malformation, which may be segmental or diffuse. Affected papillae are enlarged and billowy, due to markedly enlarged inner medullary collecting ducts (IMCD), which contain small, mobile ductal stones. Patients had frequent dilation of Bellini ducts, with occasional mineral plugs. Stones may form over white (Randall's) plaque, but most renal pelvic stones are not attached, and have a similar morphology as ductal stones, which are a mixture of calcium oxalate and apatite. Patients had no abnormalities of urinary acidification or acid excretion; the most frequent metabolic abnormality was idiopathic hypercalciuria. Although both Runx2 and Osterix are expressed in papillae of MSK patients, no mineral deposition was seen at the sites of gene expression, arguing against a role of these genes in this process. Similar studies in idiopathic calcium stone formers showed no expression of these genes at sites of Randall's plaque. The most likely mechanism for stone formation in MSK appears to be crystallization due to urinary stasis in dilated IMCD with subsequent passage of ductal stones into the renal pelvis where they may serve as nuclei for stone formation.

Ontogeny of the Early Triassic Cynodont Thrinaxodon liorhinus (Therapsida): Cranial Morphology
Authors: Jasinoski Sandra C. , Abdala Fernando , Fernandez Vincent 
Published: January 2015

ABSTRACTThe cranial morphology of 68 Thrinaxodon liorhinus specimens, ranging in size from 30 to 96 mm in basal skull length, is investigated using both qualitative and quantitative analyses. From this comprehensive survey, we determined that nine cranial features, including five in the temporal region, separated the sample into four ontogenetic stages. A bivariate analysis of 60 specimens indicated that the skull generally increased in size isometrically, with the exception of four regions. The orbit had negative allometry, a result consistent with other ontogenetic studies of tetrapods, whereas the length of the snout, palate, and temporal region showed positive allometry. The last trend had strong positive allometry indicating that during ontogeny the length of the sagittal crest increased at a much faster rate than the rest of the skull. The large number of changes in the temporal region of the skull of Thrinaxodon may indicate a greater development of the posterior fibres of the temporalis musculature from an early ontogenetic stage. For example, the posterior sagittal crest developed much earlier in ontogeny than the anterior crest that formed in adults, and bone was deposited dorsally creating a unified posterior sagittal crest rather than having a suture that spanned the entire depth of the skull roof. In combination with the isometric height of the zygomatic arch and the almost complete absence of the zygomatic arch angulation, these ontogenetic changes suggest that there was greater development of the temporalis relative to the masseter muscles, indicating a strong posterodorsal movement of the mandible in Thrinaxodon.

Published: January 2015

AbstractCovalent functionalization has proven an effective solution for graphene to realize its revolutionary potential in real applications, whereas the platform strategy (a reactive graphene‐based material acting as the platform to undergo post‐reactions for generation of various graphene‐derived materials) is an attractive option to execute efficiently such a task. This contribution demonstrates that 2‐(3,4‐dihydroxyphenyl) pyrrolidine (DHPP) grafted graphene, G‐OH, is a competent platform. Four typical but not exclusive graphene‐derived materials have been prepared from G‐OH by using the chemical virtue of each DHPP unit having three categories totaling six reactive sites. The controlled feature of 1,3‐dipolar cycloaddition for the synthesis of G‐OH ensures that the electronic structure and properties of pristine graphene are succeeded largely by G‐OH and thus its derivatives. A promising alternative to graphene oxide, which has been widely used as a platform to prepare the graphene‐derived materials but suffers from some intrinsic disadvantages, is thus developed.
Investigating the applicability of exclusive pedestrian phase at two‐phase actuated controlled intersections
Authors: Ma Wanjing , Han Baoxin , An Kun , Zhang Nan 
Published: January 2015

SummaryThe exclusive pedestrian phase (EPP) has been used in many countries to promote walking around downtown areas by increasing the ease and convenience of pedestrian crossing. However, its applicability has not been systematically demonstrated, especially when an intersection is operated in actuated mode. This paper presents an extensive simulation‐based analysis of the applicability of EPP as compared with a normal concurrent pedestrian‐phase pattern at an isolated intersection controlled by actuated logic. Actuated signal control logics for EPP‐actuated and conventional concurrent pedestrian phase‐actuated controls are developed. Both of these control logics consider pedestrian crossing demands and can adapt to changes in vehicle traffic to reduce vehicle delay as well. A simulation model of a two‐phase controlled intersection is built and calibrated based on field data using VISSIM (PTV Planung Transport Verkehr AG in Karlsruhe, Germany). Extensive analysis is conducted to reveal fully the applicable EPP domain in terms of vehicle traffic demand, pedestrian demand, vehicle turning ratio, and pedestrian diagonal crossing ratio. The results show that the performance and applicable domain of EPP are jointly determined by those five factors. EPP significantly outperforms concurrent pedestrian phase if the vehicle turning ratio is greater than 0.6 and the pedestrian diagonal crossing ratio is greater than 0.6. These results can help traffic engineers in choosing the appropriate pedestrian‐phase patterns at actuated signalized intersections. Copyright © 2015 John Wiley & Sons, Ltd.
In vitro selection of DNAs with an increased propensity to form small circles
Authors: Rosanio Gabriel , Widom Jonathan , Uhlenbeck Olke C. 
Published: January 2015

ABSTRACTA protocol was devised to select for DNA molecules that efficiently form circles from a library of 126 base pair DNAs containing 90 randomized base pairs. After six rounds of selection, individual molecules from the library showed 20‐ to 100‐fold greater j‐factors compared with the starting library, validating the selection protocol. High‐throughput sequencing revealed a sinusoidal pattern of enrichment and de‐enrichment of A/T dinucleotides in the random region with a 10.4 base pair period associated with the helicity of DNA. A similar, but more moderate pattern of C/G dinucleotides was offset by precisely half a helical turn. While C/G dinucleotide enrichments were evenly distributed, A/T dinucleotide enrichments displayed a preference to cluster in individual DNA molecules. The most highly enriched 10 base pair sequences in the random region contained adjacent blocks of A/T and C/G trinucleotides present in some, but not all, rapidly cyclizing molecules. The phased dinucleotide enrichments closely match those present in accurately mapped yeast nucleosomes, confirming the importance of DNA bending in nucleosome formation. However, at certain sites the nucleosomal DNAs show dinucleotide enrichments that differ substantially from the cyclization data. These discrepancies can often be correlated with sequence specific contacts that form between histones and DNA. © 2015 Wiley Periodicals, Inc. Biopolymers 103: 303–320, 2015.
Uptake and cellular distribution of nucleolar targeting peptides (NrTPs) in different cell types
Authors: Rodrigues Margarida , Andreu David , Santos Nuno C. 
Published: January 2015

ABSTRACTNucleolar targeting peptides (NrTPs) are a family of cell penetrating peptides (CPPs) derived from crotamine, a rattlesnake venom toxin. They were named NrTPs for their remarkable nucleolus‐homing properties and have been studied for their potential as drug delivery vehicles. Live cell microscopy experiments were conducted to monitor NrTP uptake and distribution in different cell types, including primary cells (PBMCs and erythrocytes) and different immortalized cell lines (HeLa, BHK21, BV‐173, and MOLT‐4). Uptake dependence on cell type (primary vs. immortalized, suspension vs. adherent, cancer vs. healthy cells), peptide concentration and cell viability were evaluated. To gain further insight on the internalization mechanism, uptake kinetics was also monitored. Results showed the uptake and distribution pattern as strongly dependent on peptide sequence, peptide concentration and membrane constituents. Under similar conditions, NrTP6 is more internalized than NrTP1, NrTP2 and NrTP5. Additionally, while internalization of NrTP7 and NrTP8 may cause cytotoxicity, NrTP6 is noncytotoxic. Higher peptide concentrations can be correlated to nucleolar targeting, although even at low concentrations a residual number of cells reveal positive nucleolar labeling. NrTPs were successfully internalized into all cell types tested except erythrocytes. © 2015 Wiley Periodicals, Inc. Biopolymers (Pept Sci) 104: 101–109, 2015.

AbstractRecombinant protein overexpression of large proteins in bacteria often results in insoluble and misfolded proteins directed to inclusion bodies. We report the application of shear stress in micrometer‐wide, thin fluid films to refold boiled hen egg white lysozyme, recombinant hen egg white lysozyme, and recombinant caveolin‐1. Furthermore, the approach allowed refolding of a much larger protein, cAMP‐dependent protein kinase A (PKA). The reported methods require only minutes, which is more than 100 times faster than conventional overnight dialysis. This rapid refolding technique could significantly shorten times, lower costs, and reduce waste streams associated with protein expression for a wide range of industrial and research applications.

Nanocrystalline M–MOF‐74 as Heterogeneous Catalysts in the Oxidation of Cyclohexene: Correlation of the Activity and Redox Potential
Authors: Ruano Daniel , Díaz‐García Manuel , Alfayate Almudena , Sánchez‐Sánchez Manuel 
Published: January 2015

AbstractIn some aspects, the potential of metal–organic framework (MOF) materials as heterogeneous catalysts has been realized, at least in an academic context. However, one of their most promising catalytic properties, that is, the presence of open metal sites, is far from understood properly. In this work, a series of M–MOF‐74 (M=Mn, Co, Ni, Cu, Zn) materials, prepared under sustainable conditions, was tested systematically in the oxidation of cyclohexene, which can proceed by either radical or epoxidation routes. Under the optimized reaction conditions, the radical route is spontaneous to some extent and it is enhanced in the presence of any M–MOF‐74 that has a metal with a redox character but not Zn. However, the epoxidation of cyclohexene is also promoted by a redox catalyst in such a way that the conversion correlates qualitatively with the redox potential of the metal. Thus, for the first time, a chemical property of M is correlated with the catalytic activity of the M–MOF‐74 family.
