Aim: The study was carried out to ascertain how Hamelia patens would be valuable in sustaining diversity of beneficial insects.
Study Design: Investigative cross-sectional study.
Place and Duration of Study: The study was carried out at University of Port Harcourt, Nigeria. The insects and plants were processed for identification at the Laboratories of the Department of Animal and Environmental Biology and Plant Science and Biotechnology, University of Port Harcourt, Nigeria. Identification and curation of the insects was done at Insect Museum, Ahmadu Bello University Zaria, Nigeria. The study started in June and ended in September 2018.
Methodology: The heights and canopy sizes of the Hamelia patens were measured with range pole and measuring tape. Insects associated with the floral parts of Hamelia patens were collected in the morning (08:00-10:00 am) and in the evening (4:00-06:00 pm) hours, with a sweep net. They were knockdown by pyrethrum insecticide and preserved in a bottle containing 70% ethanol. They were taxonomically grouped and sent to a taxonomist at Insect Museum, Nigeria for species identification.
Results: Fifteen (15) insect species were collected on the Hamelia patens; Megachile mephistrophelica (Grib.), Megachile cinta (Fab.), Braunisca bilunta (Enderloein.), Pterandus sp., Lilioceris sp. and Virachola antalus (Hoph.) restricted their visitation on the plants only in the morning hours, Chelonus bifoveolatus (Szepg.) and Chrysolagria nairobana (Borch.) restricted their visitation in the evening hours. The remaining species were continuous on the plants. There was no significant difference (P=.05) between the number of insect species collected on taller plants and shorter ones. There was a significant difference between the insects that visited the plants in the morning and evening hours.
Conclusion: The arrival of the insects on the Hamelia patens varied but some were time dependent. The clipping of the plant’s twigs affected the abundance of insects that visit the plant.

The case of a young Moroccan doctor who spent Four months in Congo as part of an international humanitarian military mission; he underwent surgery under spinal anesthesia for an anal fissure a week after being returned to Morocco, In the seventh-day postoperative period, acute renal failure with anuria set in, justifying the patient's transfer to an intensive care unit. Upon admission, on the eighth postoperative day, one day after readmission to the emergency room and was put on triple antibiotic therapy ,and liquid resuscitation was carried out immediately by infusion of saline isotonic solution and due to the non-improvement of the hemodynamic state after volume repletion, a vasoactive support was rapidly introduced at the initial dose of 0.2 ug / kg / min, the intravenous quinine was not immediately introduced in the emergency room because the initial thick, thin film and malaria blood smear carried out on admission were negative and the postoperative clinical context argued in favor of bacterial septic shock. A sepsis context not ruled out (blood cultures performed); a surgical revision the morning of his admission to the intensive care by under umbilical laparotomy, didn’t showed an intra-abdominal collection. Parallelly a thick film (30% of parasitized red blood cells) revealing P. falciparum, and blood smear were performed again and came back positive after a positive malaria antigen detection of specific IgMs in the indirect immunofluorescence, confirming the diagnosis. The mode of infection; is associated with the end of chemoprophylaxis rigorously followed up till Finally, the possibility of pernicious malaria aggravating the initial acute renal failure and hipocalcemia is also discussed.

Introduction: Malaria is the major cause of mortality worldwide. Accurate diagnosis is key for effective management of the disease. Non-adherence to diagnosis guidelines by primary healthcare (PHC) workers affects quality healthcare provisions. Job aid posters help enhance adherence to guidelines for several diseases. Thus, this study determined PHC worker’s use of job aid posters and identified factors affecting its use as a guide for malaria diagnosis.
Methods: The study was a hospital-based cross-sectional survey, a multistage sampling technique was used to select 384 PHC workers from seventy-eight PHC facilities in Ibadan Oyo State, Nigeria. A semi-structured, self-administered questionnaire was used to obtain participant’s socio-demographic characteristics, knowledge and adherence to malaria diagnosis guidelines, and factors affecting the use of job aid posters as a guide for malaria diagnosis. Data analysis was done using descriptive statistics, chi-square, and logistic regression with P-Value=0.05 declared as statistically significant.
Results: Two hundred and forty-four (63.5%) PHC workers were knowledgeable about malaria diagnosis guidelines whereas only 58.1% of the total respondents adhere to the guidelines. Just less than half (45.3%) of participants uses job aid posters always. Knowledge of malaria diagnosis guidelines (AOR = 0.272, 95% C.I = 0.115-0.643), comprehensiveness of job aid poster (AOR = 0.345, 95% C.I = 0.148-0.807), physical integrity of job aid posters (AOR = 0.219, 95% C.I = 0.092-0.522), and positioning of job aid posters (AOR = 5.704, 95% C.I = 2.375-13.67) were significant predictors of use of job aid posters for malaria diagnosis.
Conclusion: the healthcare worker’s adherence to guidelines for malaria diagnosis was inadequate. Provision of comprehensive job aid posters on malaria diagnosis, replacement of damaged ones, and strategic display of the job aid posters is recommended to enhance use and adherence.

Aims: The aim of this work is to know the interrelationships of the physicochemical parameters likely to explain algal blooms and to identify the potential structures of molecules that can be secreted in an Ivorian lagoon environment: the Ebrié lagoon.
Methodology: Nine stations, selected according to natural influences and anthropogenic pressure, were subject to physicochemical monitoring. It consisted of in situ measurements (temperature, salinity, dissolved oxygen, electrical conductivity) and chemical analyses in the laboratory (pH, nitrates, nitrites). In addition to these measurements, observations were noted in the field, namely the climatology of the day, the colour and smell of the water, the presence of algae (micro and / or macroalgae).
Results: Our results showed that the waters of the Ebrié lagoon are warm (T > 25 °C), with a pH between 6 and 9 and variable salinity. Salinity would be a discriminating factor for the presence of macroalgae. The nutrients levels (nitrates and nitrites) remain within the limits of acceptability.
Conclusion: The waters in our study area are favorable for algal blooms. Given the nuisances associated with algal blooms, the study proposes some structures of toxins which can be secreted on the basis of a literature review.

Published: August 2021

Several methods exist when seeking to experimentally evaluate the antioxidant properties of a natural bioactive substance. In the case of flavonoids, the methods used are mainly based on the experimental determination of the percentage of inhibition (IC50) or the redox potential (E).
In the present work, a prediction study of the redox potential E and the inhibitory concentration LogIC50 was carried out, using the AM1 and HF/6-311G(d,p) method.
At the end of this study, three (03) QSPR models were validated and retained, one (01) for the prediction of the redox potential and four (02) for the prediction of the inhibitory concentration :

The Redox Prediction Model, developed at the AM1 approximation level, for which 96.43 of the experimental variance is explained by the descriptors :

E= -0,29 + 0,22EHomo + 0,11ELumo - 0,05

The Inhibitory Concentration Prediction Models, developed at the AM1 level, for which 96.35⁒ of the experimental variance is explained by the descriptors :

LogIC50 = -4,92 + 11,37EHomo + 34,36ELumo + 0,67

The Inhibitory Concentration Prediction Model, developed at the HF/6-311G level (d, p), for which 99.96⁒ of the experimental variance is explained by the descriptors. LogIC50 = 62,40 + 80,25 EHomo - 28,44Elumo + 52,01S - 71,26 η - 6,11μ

The development of these QSPR models represents a significant advance in predicting the antioxidant properties of bioactive molecules such as flavonoids based on descriptors calculated by quantum chemical methods.

AbstractPurposeMedical images are important in diagnosing disease and treatment planning. Computer algorithms that describe anatomical structures that highlight regions of interest and remove unnecessary information are collectively known as medical image segmentation algorithms. The quality of these algorithms will directly affect the performance of the following processing steps. There are many studies about the algorithms of medical image segmentation and their applications, but none involved a bibliometric of medical image segmentation.MethodsThis bibliometric work investigated the academic publication trends in medical image segmentation technology. These data were collected from the Web of Science (WoS) Core Collection and the Scopus. In the quantitative analysis stage, important visual maps were produced to show publication trends from five different perspectives including annual publications, countries, top authors, publication sources, and keywords. In the qualitative analysis stage, the frequently used methods and research trends in the medical image segmentation field were analyzed from 49 publications with the top annual citation rates.ResultsThe analysis results showed that the number of publications had increased rapidly by year. The top related countries include the Chinese mainland, the United States, and India. Most of these publications were conference papers, besides there are also some top journals. The research hotspot in this field was deep learning‐based medical image segmentation algorithms based on keyword analysis. These publications were divided into three categories: reviews, segmentation algorithm publications, and other relevant publications. Among these three categories, segmentation algorithm publications occupied the vast majority, and deep learning neural network‐based algorithm was the research hotspots and frontiers.ConclusionsThrough this bibliometric research work, the research hotspot in the medical image segmentation field is uncovered and can point to future research in the field. It can be expected that more researchers will focus their work on deep learning neural network‐based medical image segmentation.

AbstractPurposeTo evaluate the transient artifact augmentation of microtubes in magnetic resonance imaging by fluid injection.MethodsTwenty‐one fluorinated ethylene propylene catheters (inner diameter 760 μm) were filled with three different contrast media at various concentrations (Ferucarbotran, Resovist®, Bayer Schering Pharma; Manganese dichloride, MnCl2, Sigma‐Aldrich; Gadobutrol, Gadovist®, Bayer Schering Pharma). Artifact appearance was determined in an ex vivo phantom at 1.5 T using three different sequences: T1‐weighted three‐dimensional volume interpolated breath‐hold examination, T2‐weighted turbo spin echo, and T1‐weighted fast low angle shot. Catheter angulation to the main magnetic field (B0) was varied. Influence of parameters on artifact diameters was assessed with a multiple linear regression similar to an analysis of variance.ResultsArtifact diameter was significantly influenced by the contrast agent (p < 0.001), concentration of the contrast agent (p < 0.001), angulation of the phantom to B0 with the largest artifact at 90° (p < 0.001), and encoding direction with a larger diameter in phase encoding direction (PED,p < 0.001). Mean artifact diameters at 90° angulation to B0 in PED were 18.5 ± 5.4 mm in 0.5 mmol/ml Ferucarbotran, 8.7 ± 2.5 mm in 1 mmol/ml Gadobutrol, and 11.6 ± 4.6 mm in 5 mmol/ml MnCl2.ConclusionsFluid‐based contrast agents might be applied to interventional devices and thus temporarily augment the artifact ensuring both visibility and safe navigation.

AbstractObjectiveTo understand the natural disease upper limb progression over 3 years of ambulatory and non‐ambulatory patients with Duchenne muscular dystrophy (DMD) using functional assessments and quantitative magnetic resonance imaging (MRI) and to exploratively identify prognostic factors.MethodsForty boys with DMD (22 non‐ambulatory and 18 ambulatory) with deletions in dystrophin that make them eligible for exon 53‐skipping therapy were included. Clinical assessments, including Brooke score, motor function measure (MFM), hand grip and key pinch strength, and upper limb distal coordination and endurance (MoviPlate), were performed every 6 months and quantitative MRI of fat fraction (FF) and lean muscle cross sectional area (flexor and extensor muscles) were performed yearly.ResultsIn the whole population, there were strong nonlinear correlations between outcome measures. In non‐ambulatory patients, annual changes over the course of 3 years were detected with high sensitivity standard response mean (|SRM| ≥0.8) for quantitative MRI‐based FF, hand grip and key pinch, and MFM. Boys who presented with a FF<20% and a grip strength >27% were able to bring a glass to their mouth and retained this ability in the following 3 years. Ambulatory patients with grip strength >35% of predicted value and FF <10% retained ambulation 3 years later.InterpretationWe demonstrate that continuous decline in upper limb strength, function, and MRI measured muscle structure can be reliably measured in ambulatory and non‐ambulatory boys with DMD with high SRM and strong correlations between outcomes. Our results suggest that a combination of grip strength and FF can be used to predict important motor milestones.

AbstractBackgroundIntracerebral hemorrhage (ICH) causes neurotransmitter release, oligemia, membrane depolarization, mitochondrial dysfunction, and results in the high rate of mortality and functional disability. Here, we focus on PTEN‐induced kinase 1 (PINK1), a mitochondrial‐targeted protein kinase, and explore its role in ICH progression.MethodsThe qPCR and Western blot were performed to examine the expression of PINK1 in ICH patients and mouse model. PINK1 gain‐ and loss‐of‐function mice were used to evaluate their protective role on brain injury and behavioral disorders. Flow cytometry was carried out, mitochondrial membrane potential and reactive oxygen species production were detected to explore the distribution and neuroprotective function of PINK1.ResultsPINK1 mRNA was upregulated, however, its protein was downregulated in ICH patients. The reduction of PINK1 was mainly happened in microglial cells in ICH model. Overexpression of PINK1 is able to rescue ICH‐induced behavioral disorders. PINK1 protects ICH‐induced brain injury by promoting mitochondrial autophagy in microglia.ConclusionPINK1 possesses a neuroprotective role and antagonizes ICH by promoting mitochondrial autophagy, which may be of value as a therapeutic target for ICH treatment.

AbstractVisual optical information encryption–decryption and anti‐counterfeiting (IEDAC) technology play a vital role in the field of information security. Recent luminescent information encryption technologies face the disadvantages of depending on external large‐scale stimulus decryption equipment, inability to read out repeatedly, and information leakage, impeding the practical applications of luminescence encryption. Here, an integrated luminescent IEDAC chip is proposed, which provides a convenient approach to store and decipher pre‐patterned luminescence information based on laser engraved template and film heater. The luminescent encryption chip contains a double‐layer structure made up of long persistent phosphors based on SrCaGa4O8 host and a laser induced graphene heater, which makes it possible to decrypt information on a single chip. This design enables dual‐mode (photoluminescence/long persistent luminescence), dual‐color (blue/yellow‐green), and multi‐level IEDAC function, providing a novel insight and integrated strategy for implementing advanced IEDAC technologies.

Published: August 2021

AbstractFluorescent microbeads are widely used for applications in life sciences and medical diagnosis. The spectral contrast and sharpness of photoluminescence are critical in the utilities of microbeads for imaging and multiplexing. Here, microbeads capable of generating single‐peak laser emission with a sub‐nanometer linewidth are demonstrated. The microbeads are made of quantum dots that are tightly packed and crosslinked via ligand exchange for high optical gain and refractive index as well as material stability. Bright single‐mode lasing with no photobleaching is achieved with particle diameters as small as 1.5 µm in the air. Sub‐nm lasing emission is maintained even inside high‐index surroundings, such as organic solvents and biological tissues. Feasibility of intracellular tagging and multi‐color imaging in vivo is demonstrated.

Published: August 2021

AbstractAligned carbon nanotube (A‐CNT) films are expected to be an ideal channel material for constructing field‐effect transistors (FETs) that outperform conventional transistors, and multiple methods are developed to fabricate A‐CNT films with high semiconducting purity, good alignment, and high density. However, the reported A‐CNTs‐based FETs are almost all depletion‐mode FETs and suffer from poor subthreshold swing (SS). In this study, enhancement‐mode (E‐mode) FETs based on A‐CNT films are fabricated by systematically optimizing the channel material and CNT/high‐k/metal gate stack. The carrier mobility in top‐gate A‐CNT FETs reaches a maximum value of 1850 cm2 V−1 s−1, which is near that of chemical‐vapor deposition grown individual CNTs and sets a record among A‐CNT films. The fabricated 200 nm‐gate length p‐type A‐CNT FETs present a SS of 73 mV dec−1, the transconductance of 1 mS µm−1, and an on‐current of 1.18 mA µm−1 at a bias of ‐1 V, indicating a real performance exceeding that of commercial Si‐based transistors at a similar gate length. Based on the high‐performance and uniform E‐mode FETs, ring oscillators with stage numbers 5, 7, 9, and 11 are fabricated with an optimized design and high yield, exhibiting a record propagation gate delay of 11.3 ps among CNT‐ and other nanomaterial‐based ICs.

AbstractDeveloping highly efficient photocatalysts for artificial photosynthesis is one of the grand challenges in solar energy conversion. Among advanced photoactive materials, conjugated porous polymers (CPPs) possess a powerful combination of high surface areas, intrinsic porosity, cross‐linked nature, and fully π‐conjugated electronic systems. Here, based on these fascinating properties, organic–inorganic hybrid heterostructures composed of CPPs and TiO2 for the photocatalytic CO2 reduction and H2 evolution from water are developed. The study is focused on CPPs based on the boron dipyrromethene (BODIPY) and boron pyrrol hydrazine (BOPHY) families of compounds. It is shown that hybrid photocatalysts are active for the conversion of CO2 mainly into CH4 and CO, with CH4 production 4 times over the benchmark TiO2. Hydrogen evolution from water surpassed by 37.9‐times that of TiO2, reaching 200 mmol gcat−1 and photonic efficiency of 20.4% in the presence of Pt co‐catalyst (1 wt% Pt). Advanced photophysical studies, based on time‐resolved photoluminescence and transient absorption spectroscopy, reveal the creation of a type II heterojunction in the hybrids. The unique interfacial interaction between CPPs and TiO2 results in longer carriers’ lifetimes and a higher driving force for electron transfer, opening the door to a new generation of photocatalysts for artificial photosynthesis.
