Aim: to assess the levels of some inflammatory markers in malaria parasite-infected subjects attending Rivers State University Teaching Hospital, Port Harcourt, Nigeria.
Study Design: Cross-sectional study.
Place and Duration of Study: Rivers State University Teaching Hospital and Pamel Laboratories & Diagnostics Limited, both in Port Harcourt, between July 2023 and July 2024.
Methodology: A total of 150 individuals were initially screened for various health conditions, resulting in 89 subjects deemed suitable for the study. This group comprised 43 males and 46 females, with 29 participants serving as controls and 60 participants as malaria-positive subjects. Blood specimens were obtained from each subject, and serum samples were extracted after centrifugation. These serum samples were used to assay IL-6, TNF-α using the ELISA method. Additionally, subjects were categorized based on parasitaemia severity and malaria treatment history. Data was analyzed using GraphPad Prism version 9.02. Descriptive statistics involving the use of Mean and Standard Deviation. Inferential Statistics involving the use of one-way ANOVA (PostHoc: Tukey’s multiple comparison test), students statistical t-test, and Pearson’s correlation. Statistical significance was set at p < 0.05.
Results: The study found no significant differences in IL-6 (p=0.8878), TNF-α (0.0961), levels between control and malaria-positive subjects. However, based on malaria severity, there were no significant differences in TNF-α (p=0.1993) levels among mild, moderate, and high parasitaemia cases. However, IL-6 (p=0.0002) levels were elevated in high parasitaemia cases. Malaria treatment normalized all markers within 1-8 months, except IL-6 (p=0.0423), which remained significantly elevated in subjects with a history of malaria within 9-12 months. These results suggest that malaria parasitaemia does not significantly alter inflammatory markers such as IL-6 and TNF-α. The severity of parasitaemia influences IL-6, while malaria treatment typically returns most markers to baseline within 8 months, except for IL-6.
Conclusion: Further research studies need to explore the mechanisms behind persistent IL-6 elevation post-malaria treatment and the potential long-term effects of other inflammatory markers in malaria patients.

Performance of IRI‐2012 model during a deep solar minimum and a maximum year over global equatorial regions
Authors: Kumar Sanjay 
Published: May 2016

AbstractPresent paper inspects the prediction capability of the latest version of the International Reference Ionosphere (IRI‐2012) model in predicting the total electron content (TEC) over seven different equatorial regions across the globe during a very low solar activity phase 2009 and a high solar activity phase 2012. This has been carried out by comparing the ground‐based Global Positioning System (GPS)‐derived VTEC with those from the IRI‐2012 model. The observed GPS‐TEC shows the presence of winter anomaly which is prominent during the solar maximum year 2012 and disappeared during solar minimum year 2009. The monthly and seasonal mean of the IRI‐2012 model TEC with IRI‐NeQ topside has been compared with the GPS‐TEC, and our results showed that the monthly and seasonal mean value of the IRI‐2012 model overestimates the observed GPS‐TEC at all the equatorial stations. The discrepancy (or over estimation) in the IRI‐2012 model is found larger during solar maximum year 2012 than that during solar minimum year 2009. This is a contradiction to the results recently presented by Tariku (2015) over equatorial regions of Uganda. The discrepancy is found maximum during the December solstice and a minimum during the March equinox. The magnitude of discrepancy in the IRI‐2012 model showed longitudinal dependent which maximized in western longitude sector during both the years 2009 and 2012. The significant discrepancy in the IRI‐2012 model observed during the solar minimum year 2009 could be attributed to larger difference between F10.7 flux and EUV flux (26–34 nm) during low solar activity period 2007–2009 than that during high solar activity period 2010–2012. This suggests that to represent the solar activity impact in the IRI model, implementation of new solar activity indices is further required for its better performance.

Published: May 2016

AbstractThe fate of subducted oceanic slabs can provide important clues to plate reconstruction through Earth history. Since oceanic slabs in continental collision zones are typically not well preserved, ancient subduction zones have rarely been imaged by geophysical techniques. Here we present an exception from the Darbut belt in the Junggar accretionary collage in the southern Altaids of Asia. We deployed a 182 km long magnetotelluric (MT) profile including 60 broadband sounding sites across the belt. Quality off‐diagonal impedances were inverted by a three‐dimensional scheme to image resistivities beneath the profile. The resistivity model along with MT impedance phase ellipses and induction vectors were tested and interpreted in detail. Combining geological and geophysical observations, mineral physical experiment, and geodynamic modeling results, the MT transect suggests a fossil intraoceanic subduction zone during the Late Paleozoic in the western Junggar that has been well preserved due to lack of significant subsequent tecto‐thermal events.
Understanding the structure of changes in the Southern Ocean eddy field
Authors: Meredith Michael P. 
Published: May 2016

AbstractThe Southern Ocean is riddled with mesoscale eddies. Although just a few kilometers in size, these loops and vortices are key parts of the climate system and are important in controlling how ocean circulation responds to changes in forcing. Observations reveal that changes in the intensity of these eddies vary significantly around the Southern Ocean. This contrasts with the nature of the atmospheric forcing, which is more zonally symmetric. Recent progress using high‐resolution modeling has pinpointed where intrinsic variability dominates over wind‐driven variability; and hence, the areas where future responses to climatic changes in forcing are likely to be clearest.

Published: May 2016

AbstractThe ionosphere scale height is one of the most significant ionospheric parameters, which contains information about the ion and electron temperatures and dynamics in upper ionosphere. In this paper, an empirical orthogonal function (EOF) analysis method is applied to process all the ionospheric radio occultations of GPS/COSMIC (Constellation Observing System for Meteorology, Ionosphere, and Climate) from the year 2007 to 2011 to reconstruct a global ionospheric scale height model. This monthly medium model has spatial resolution of 5° in geomagnetic latitude (−87.5° ~ 87.5°) and temporal resolution of 2 h in local time. EOF analysis preserves the characteristics of scale height quite well in the geomagnetic latitudinal, anural, seasonal, and diurnal variations. In comparison with COSMIC measurements of the year of 2012, the reconstructed model indicates a reasonable accuracy. In order to improve the topside model of International Reference Ionosphere (IRI), we attempted to adopt the scale height model in the Bent topside model by applying a scale factor q as an additional constraint. With the factor q functioning in the exponent profile of topside ionosphere, the IRI scale height should be forced equal to the precise COSMIC measurements. In this way, the IRI topside profile can be improved to get closer to the realistic density profiles. Internal quality check of this approach is carried out by comparing COSMIC realistic measurements and IRI with or without correction, respectively. In general, the initial IRI model overestimates the topside electron density to some extent, and with the correction introduced by COSMIC scale height model, the deviation of vertical total electron content (VTEC) between them is reduced. Furthermore, independent validation with Global Ionospheric Maps VTEC implies a reasonable improvement in the IRI VTEC with the topside model correction.
Water balance complexities in ephemeral catchments with different land uses: Insights from monitoring and distributed hydrologic modeling

Published: May 2016

AbstractAlthough ephemeral catchments are widespread in arid and semiarid climates, the relationship of their water balance with climate, geology, topography, and land cover is poorly known. Here we use 4 years (2011–2014) of rainfall, streamflow, and groundwater level measurements to estimate the water balance components in two adjacent ephemeral catchments in south‐eastern Australia, with one catchment planted with young eucalypts and the other dedicated to grazing pasture. To corroborate the interpretation of the observations, the physically based hydrological model CATHY was calibrated and validated against the data in the two catchments. The estimated water balances showed that despite a significant decline in groundwater level and greater evapotranspiration in the eucalypt catchment (104–119% of rainfall) compared with the pasture catchment (95–104% of rainfall), streamflow consistently accounted for 1–4% of rainfall in both catchments for the entire study period. Streamflow in the two catchments was mostly driven by the rainfall regime, particularly rainfall frequency (i.e., the number of rain days per year), while the downslope orientation of the plantation furrows also promoted runoff. With minimum calibration, the model was able to adequately reproduce the periods of flow in both catchments in all years. Although streamflow and groundwater levels were better reproduced in the pasture than in the plantation, model‐computed water balance terms confirmed the estimates from the observations in both catchments. Overall, the interplay of climate, topography, and geology seems to overshadow the effect of land use in the study catchments, indicating that the management of ephemeral catchments remains highly challenging.
Direct Access to β‐Fluorinated Aldehydes by Nitrite‐Modified Wacker Oxidation

Published: May 2016

AbstractAn aldehyde‐selective Wacker‐type oxidation of allylic fluorides proceeds with a nitrite catalyst. The method represents a direct route to prepare β‐fluorinated aldehydes. Allylic fluorides bearing a variety of functional groups are transformed in high yield and very high regioselectivity. Additionally, the unpurified aldehyde products serve as versatile intermediates, thus enabling access to a diverse array of fluorinated building blocks. Preliminary mechanistic investigations suggest that inductive effects have a strong influence on the rate and regioselectivity of the oxidation.

AbstractIntroductionThe dopaminergic (DA) system plays important roles in addiction. However, human DA neurons from drug‐dependent subjects were not available for study until recent development in inducible pluripotent stem cells (iPSCs) technology.MethodsIn this study, we produced DA neurons differentiated using iPSCs derived from opioid‐dependent and control subjects carrying different 3′ VNTR (variable number tandem repeat) polymorphism in the human dopamine transporter (DAT or SLC6A3). In addition, the effects of valproic acid (VPA) exposures on iPSC‐derived human DA neurons are also examined.ResultsWe present the first evidence suggesting that the 3′ VNTR polymorphism in the hDAT gene affects DAT expression level in iPSC‐derived human DA neurons. In human DA neurons, which provide an appropriate cellular milieu, VPA treatment alters the expression of several genes important for dopaminergic neuron function including DAT, Nurr1, and TH; this might partly explain its action in regulating addictive behaviors. VPA treatment also significantly increased DA D2 receptor (Drd2) expression, especially in the opioid‐dependent iPSC cell lines.ConclusionsOur data suggest that human iPSC‐derived DA neurons may be useful in in vitro experimental model to examine the effects of genetic variation in gene regulation, to examine the underlying mechanisms in neurological disorders including drug addiction, and to serve as a platform for therapeutic development.

AbstractAtypical teratoid rhabdoid tumors (AT/RT) are characterized by mutations and subsequent inactivation of SMARCB1 (INI1, hSNF5), a predilection for very young children and an unfavorable outcome. The European Registry for rhabdoid tumors (EU‐RHAB) was established to generate a common European database and to establish a standardized treatment regimen as the basis for phase I/II trials. Thus, genetic analyses, neuropathologic and radiologic diagnoses, and a consensus treatment regimen were prospectively evaluated. From 2005 to 2009, 31 patients with AT/RT from four countries were recruited into the registry study Rhabdoid 2007 and treated with systemic and intraventricular chemotherapy. Eight patients received high‐dose chemotherapy, 23 radiotherapy, and 17 maintenance therapy. Reference evaluations were performed in 64% (genetic analyses, FISH, MLPA, sequencing) up to 97% (neuropathology, INI1 stain). Germ‐line mutations (GLM) were detected in 6/21 patients. Prolonged overall survival was associated with age above 3 years, radiotherapy and achievement of a complete remission. 6‐year overall and event‐free survival rates were 46% (±0.10) and 45% (±0.09), respectively. Serious adverse events and one treatment‐related death due to insufficiency of a ventriculo peritoneal shunt (VP‐shunt) and consecutive herniation were noted. Acquisition of standardized data including reference diagnosis and a standard treatment schedule improved data quality along with a survival benefit. Treatment was feasible with significant but manageable toxicity. Although our analysis is biased due to heterogeneous adherence to therapy, EU‐RHAB provides the best available basis for phase I/II clinical trials.
