Depletion of folate receptor β-expressing macrophages alleviates bleomycin-induced experimental skin fibrosis (2014)

These results indicated that anti-FRβ-PE38 treatment efficiently depleted FRβ-expressing macrophages and consequently alleviated BLM-induced skin fibrosis.
Long term implications of covid-19 in pregnancy (2022)

Complications in pregnancy, including maternal and perinatal deaths, increased with each wave of the covid-19 pandemic. By contrast, serious illness fell in other high risk groups because of vaccines and approved treatments. 1 More than a year after the UK's Joint Committee on Vaccination and Immunisation (JVCI) opened up covid-19 vaccination to pregnant women, 40% of women giving birth have still not received a first dose. 2 This is despite a positive benefit-risk profile, endorsement in guidelines, and public health campaigns. Worryingly, 69.5% of black women giving birth have not received any covid-19 vaccine.
Human-chimpanzee co-existence in non-protected areas in Sierra Leone, West Africa (2018)

Wild chimpanzees (Pan troglodytes) populations are facing a serious risk of extinction and the main global threat is habitat conversion for subsistence and commercial agriculture. The western chimpanzee subspecies (Pan troglodytes verus) has been recently categorised as Critically Endangered by the IUCN red list because in the past 50 years its population has drastically reduced of more than 80% as a result of poaching, loss of habitat and habitat fragmentation due to human activities. Sierra Leone harbors the third largest western chimpanzee population but more than half of it lives in unprotected areas with a significant competition between people and chimpanzees for resources in areas dominated by farming activities where wild chimpanzees forage on crops. This thesis explores the agricultural challenges facing farmers and their attitudes and perceptions towards chimpanzees in four rural areas of Sierra Leone. Wildlife was reported to be the main agricultural problem although chimpanzees were not ranked within the 3 most destructive species. Chimpanzees consumed semi-domesticated oil palm resources and cultivated fruits, and this is negatively viewed by farmers. In general, farmers perceived chimpanzees more destructive than dangerous. Between April 2016 and May 2017, we conducted a camera trap survey in one of the rural areas previously surveyed with the aim to analyse the ecological and anthropogenic drivers of chimpanzee occurrence across a highly degraded and human-impacted landscape in the south-western district of Moyamba in Sierra Leone. The model showed that chimpanzee abundance across this landscape is affected by the distance to roads and proximity to swamps. However, settlements and human proximity did not influence in chimpanzee abundance. Farmers’ tolerance and low hunting pressure are argued to be some of the reasons chimpanzees still persist in these degraded landscapes. Finally, this study also provides a preliminary insight into the demographics, group structure and ranging of unhabituated chimpanzees living in a non-protected landscape. Overall, we expect that the results of this thesis will contribute to a better understanding of how chimpanzees live in degraded landscapes and its implications for conservation actions including land use planning.
Field Evaluation of Endotoxin Air Sampling Assay Methods (1997)

This study tested the importance of filter media, extraction and assay protocol, and bioaerosol source on the determination of endotoxin under field conditions in swine and poultry confinement buildings. Multiple simultaneous air samples were collected using glass fiber (GF) and polycarbonate (PC) filters, and these were assayed using two methods in two separate laboratories: an endpoint chromogenic Limulus amebocyte lysate (LAL) assay (QCL) performed in water and a kinetic chromogenic LAL assay (KQCL) performed in buffer with resistant-parallel line estimation analysis (KLARE). In addition, two aqueous filter extraction methods were compared in the QCL assay: 120 min extraction at 22 degrees C with vigorous shaking and 30 min extraction at 68 degrees C with gentle rocking. These extraction methods yielded endotoxin activities that were not significantly different and were very highly correlated. Reproducibility of endotoxin determinations from duplicate air sampling filters was very high (Cronbach alpha all > 0.94). When analyzed by the QCL method GF filters yielded significantly higher endotoxin activity than PC filters. QCL and KLARE methods gave similar estimates for endotoxin activity from PC filters; however, GF filters analyzed by the QCL method yielded significantly higher endotoxin activity estimates, suggesting enhancement of the QCL assay or inhibition of the KLARE asay with GF filters. Correlation between QCL-GF and QCL-PC was high (r = 0.98) while that between KLARE-GF and KLARE-PC was moderate (r = 0.68). Analysis of variance demonstrated that assay methodology, filter-type, barn-type, and interactions between assay and filter-type and between assay and barn-type were important factors influencing endotoxin exposure assessment.
Periprosthetic Patellar Fracture after an Open Knee Dislocation (2005)

We present a patient who sustained an open knee dislocation with a periprosthetic fracture of the patella and who was treated satisfactorily with tension band wiring and a conservative rehabilitation program. In addition to describing this unique combination of injuries, we review the literature on the treatment of periprosthetic patellar fractures. Although internal fixation of these fractures historically has provided unpredictable results, we think that it is warranted if the patella has adequate bone stock.
The Past, Present, and (Possible) Future of Serologic Testing for Lyme Disease (2016)

Lyme disease prevails as the most commonly transmitted tick-borne infection in the United States, and serologic evaluation for antibodies to Borrelia burgdorferi remains the recommended modality for diagnosis. This review presents a brief historical perspective on the evolution of serologic assays for Lyme disease and provides a summary of the performance characteristics for the currently recommended two-tiered testing algorithm (TTTA). Additionally, a recently proposed alternative to the traditional TTTA is discussed, and novel methodologies, including immuno-PCR and metabolic profiling for Lyme disease, are outlined.
Coulombic self-ordering upon charging a large-capacity layered cathode material for rechargeable batteries (2019)

Lithium- and sodium-rich layered transition-metal oxides have recently been attracting significant interest because of their large capacity achieved by additional oxygen-redox reactions. However, layered transition-metal oxides exhibit structural degradation such as cation migration, layer exfoliation or cracks upon deep charge, which is a major obstacle to achieve higher energy-density batteries. Here we demonstrate a self-repairing phenomenon of stacking faults upon desodiation from an oxygen-redox layered oxide Na<sub>2</sub>RuO<sub>3</sub>, realizing much better reversibility of the electrode reaction. The phase transformations upon charging A<sub>2</sub>MO<sub>3</sub> (A: alkali metal) can be dominated by three-dimensional Coulombic attractive interactions driven by the existence of ordered alkali-metal vacancies, leading to counterintuitive self-repairing of stacking faults and progressive ordering upon charging. The cooperatively ordered vacancy in lithium-/sodium-rich layered transition-metal oxides is shown to play an essential role, not only in generating the electro-active nonbonding 2p orbital of neighbouring oxygen but also in stabilizing the phase transformation for highly reversible oxygen-redox reactions.
Use of supercritical fluid technology to prepare efficient nanocomposite foams for environmental protection purpose (2009)

This work reports on the preparation of novel nanocomposite foams that are efficient broadband microwave absorbers. Carbon nanotubes are first successfully dispersed into PCL and PMMA by melt blending. Then, foaming is promoted by supercritical CO2 by depressurization. Regular cellular structures are obtained in both cases with cells size around 10-50μm. The electromagnetic interference (EMI) shielding efficiency of these materials are then evaluated and compared to the non-foamed nanocomposites.
GaAs random laser (2004)

We demonstrate two-threshold random laser emission in the mixtures of GaAs powder with Al2O3 powder. The dilution of GaAs powder with Al2O3 powder helps to maximize the output efficiency of the stimulated emission.
Research for Face Recognition Based on Gabor Wavelet and Sparse Representation (2014)

On the basis of research for sparse representation and Gabor wavelet, a new method for face recognition combined Gabor with representation is proposed in this paper. Gabor wavelet transformation is used for face image from the training image set to obtain facial features, the over-complete dictionary is built by the Gabor features from all training set, and the sparse facial feature is obtained by sparse representation algorithm. Finally, the classifier based on fusion is designed for face recognition. The experimental results show that the improved method can extract facial features and structure information more effectively, and it also can improve face recognition rate greatly.

A Theoretical Design Approach for Passive Shimming of a Magic-Angle-Spinning NMR Magnet (2015)

This paper presents a passive shimming design approach for a magic-angle-spinning (MAS) NMR magnet. In order to achieve a 1.5-T magic-angle field in NMR samples, we created two independent orthogonal magnetic vector fields by two separate coils: the dipole and solenoid. These two coils create a combined 1.5-T magnetic field vector directed at the magic angle (54.74° from the spinning axis). Additionally, the stringent magnetic field homogeneity requirement of the MAS magnet is the same as that of a solenoidal NMR magnet. The challenge for the magic-angle passive shimming design is to correct both the dipole and solenoid magnetic field spherical harmonics with one set of iron pieces, the so-called ferromagnetic shimming. Furthermore, the magnetization of the iron pieces is produced by both the dipole and solenoid coils. In our design approach, a matrix of 2 mm by 5 mm iron pieces with different thicknesses was attached to a thin-walled tube, 90-mm diameter and 40-mm high. Two sets of spherical harmonic coefficients were calculated for both the dipole and solenoid coil windings. By using the multiple-objective linear programming optimization technique and coordinate transformations, we have designed a passive shimming set that can theoretically reduce 22 lower-order spherical harmonics and improve the homogeneity of our MAS NMR magnet.
The Iliac Crest Cartilaginous Cap (1990)

Bone and cartilage grafts can be procured from the ilium either separately or as composite chondroosseous grafts when sufficient cartilage is present. The thickness and anatomy of this iliac cartilaginous cap was analyzed in relationship to age in 50 individuals. Histology was that of normal hyaline cartilage. The cartilage alone was more pliable with little memory when compared with auricular or septal cartilage. The cartilage/bone junction was very strong. Cartilage thickness ran from close to 1 cm at age 5 to a diminished zero at age 25.
Atomically Dispersed Ruthenium Species Inside Metal–Organic Frameworks: Combining the High Activity of Atomic Sites and the Molecular Sieving Effect of MOFs (2019)

Incorporating atomically dispersed metal species into functionalized metal-organic frameworks (MOFs) can integrate their respective merits for catalysis. A cage-controlled encapsulation and reduction strategy is used to fabricate single Ru atoms and triatomic Ru<sub>3</sub> clusters anchored on ZIF-8 (Ru<sub>1</sub> @ZIF-8, Ru<sub>3</sub> @ZIF-8). The highly efficient and selective catalysis for semi-hydrogenation of alkyne is observed. The excellent activity derives from high atom-efficiency of atomically dispersed Ru active sites and hydrogen enrichment by the ZIF-8 shell. Meanwhile, ZIF-8 shell serves as a novel molecular sieve for olefins to achieve absolute regioselectivity of catalyzing terminal alkynes but not internal alkynes. Moreover, the size-dependent performance between Ru<sub>3</sub> @ZIF-8 and Ru<sub>1</sub> @ZIF-8 is detected in experiment and understood by quantum-chemical calculations, demonstrating a new and promising approach to optimize catalysts by controlling the number of atoms.
Purification, Characterization and Substrate Specificities of Xylanase Isoenzymes fromMelanocarpus albomycesIIS 68 (2000)

The ascomycetous fungus Melanocarpus albomyces when grown on wheat straw produced seven extracellular xylanase isoenzymes, designated as la, Ib, Ic, IIa, lib, llc, and lId. All seven xylanases were purified to homogeneity by gel filtration and ion-exchange chromatography. The molecular mass (kDa) of la, lb, Ic, Ila, lIb, lIc, and lId were estimated to be 22.9, 20.7, 18.6, 31.3, 25.4, 38.5, and 34.3, respectively by SDS-PAGE, and 23.7, 20.5, 17.1, 31.7, 25.1, 39.8, and 32.2, respectively by gel filtration. The isoelectric points of Ia, lb, Ic, Ila and IIb were found to be 6.2, 6.3, 6.4, 3.7, and 4.4, respectively. The activity of the isoenzymes was dependent on the type of the xylan substrates; Xylanases Ia, lb, and Ic showed highest specific activity toward larchwood xylan (an arabinoglucuronoxylan), IIa and Ilc toward birchwood xylan (a glucuronoxylan), and llb and IId toward beechwood xylan (a glucuronoxylan). Four isoenzymes la, lb, Ic, and Ila had an arabinose-releasing property on larchwood xylan. Application of specific isoenzymes as prebleaching agents in paper manufacture is proposed.
Shake The Box’ - a 4D PTV algorithm: Accurate and ghostless reconstruction of Lagrangian tracks in densely seeded flows (2014)

The ‘Shake The Box’ (STB) PTV - method for the accurate reconstruction of particle tracks in densely seeded flows was first introduced in the scope of the 10th International Symposium on Particle Image Velocimetry (PIV13) in 2013 [Schanz 2013b]. In this first work, it was shown that the proposed method of incorporating the temporal information into the process of particle position reconstruction is able to improve results in various aspects compared to conventionally used techniques. However, only an experimental dataset was available to explore the abilities of the technique [Schanz 2013b]. In order to quantify the key features of the STB-method - and to identify the benefits and drawbacks – a scheme for the creation of synthetic tracks from input - vector volumes was created, allowing the calculation of physically (sufficiently) correct track systems at arbitrary seeding densities and time separations. Projections of such track systems on virtual cameras are used as input data for both STB, as well as an MLOS-SMART [Atkinson 2009] tomographic reconstruction algorithm. The results are compared with respect to positional accuracy of reconstructed particles, occurrence of ghost particles and reconstruction time. It is shown that, after a sufficient number of snapshots to allow for convergence of the algorithm, the STB-method is able to correctly identify nearly all particles in existence, even for high seeding density up to 0,125 particles per pixel (ppp). On the same time, the average position error stays very low (0,023 px for 0.125 ppp) – a gain of more than an order of magnitude compared to MLOS-SMART. The occurrence of ghost particles is almost completely suppressed (ghost level below 0.2 percent for 0.125 ppp). The efficient utilization of the temporal information allows a significant reduction in processing time, with STB being 4 to 6 times faster compared to MLOS-SMART. As the temporal information plays such a dominant role in the STB method – both in the gained results, as well as in the reconstruction process itself – the method cannot be described as pure particle reconstruction, but rather as a method to reconstruct the full temporal development of tracer particles within their residence in the measurement volume. Therefore it is more appropriate to speak of a track reconstruction scheme - or 4D PTV.
Alkene‐Directed N‐Attack Chemoselectivity in the Gold‐Catalyzed [2+2+1]‐Annulations of 1,6‐Enynes with N‐Hydroxyanilines (2015)

Kinetically unstable nitrones are generated from gold-catalyzed reactions of 1,6-enynes with N-hydroxyanilines, and subsequently trapped by tethered alkenes to furnish [2+2+1]-annulations. Our experimental data reveal that such nitrones arise from atypical N-attack chemoselectivity that is triggered by tethered alkenes to facilitate the key protodeauration reaction.
Phase measurement in the Kondo regime of a self assembled InAs quantum dot SQUID (2012)

We use a superconducting quantum interference device (SQUID) to detect the phase of an InAs quantum dot Josephson junction (QDJJ) in the Kondo regime. The QDJJ phase is derived from the measurement of superconducting interference. The π-junction behavior is observed for a QD with an odd electron number and the phase transition from π to 0 is observed by changing the parity of the electron number. In the Kondo regimes, we find that the QDJJ becomes a 0-junction even though the electron number is odd.
Monocyte- and Endothelial-Derived Microparticles Induce an Inflammatory Phenotype in Human Podocytes (2011)

MPs alter endocytic functions of podocytes and induce secretion of pro-inflammatory cytokines, potentially leading to glomerular inflammation in vivo and the development of proteinuria. This study identifies a potential pathophysiological role for circulating MPs in the kidney through effects on the podocyte.
Molecular Dynamics and Structural Studies of the Ets Domain-DNA Complexes (2007)

Ets family transcription factors, characterized by an evolutionary conserved Ets domain, play important roles in cell development, cell differentiation, apoptosis and tissue remodeling. All members of this family have an activation or a repression domain for DNA binding. The Ets domain has been shown to bind 5-GGAA/T-3 core motif of DNA by its wHTH (winged helix-turn-helix) structure, as determined by NMR or X-Ray crystallography analysis. A number of Ets transcription factors have been shown to be involved or directly implicated in the pathogenesis of a wide spectrum of human cancers. They are thus potential molecular targets for selective cancer therapy. Computer simulations using molecular dynamics allows monitoring the dynamics of individual atoms, thereby giving a unique insight into the structural flexibility of binary complexes between Ets-domain and a specific DNA sequence that cannot be easily extracted from laboratory experiments. Moreover, an understanding of structural motifs that influence the specificity of Ets domains is essential for antitumor drug design. Here we describe molecular and structural studies that provide a detailed description of the direct and indirect readout mechanisms of DNA recognition by Ets domains, a conserved mechanism observed in other DNA-protein complexes. Keywords: Molecular dynamics, Ets domain, DNA binding site, structure

Exergy Investigation of R410A as a ‘Drop In’ Refrigerant in a Water-Cooled Mechanical Vapor Compression Cycle (2020)

The urge to replace hydrofluorocarbons which possess high global warming potentials has taken center stage in the air conditioning industry due to both international and local policies such as the Kigali Amendment and Japan’s revised Fluorinated Gas law. This has prompted the exploration of novel refrigerants as well as their mixtures to create high performance environmentally friendly alternatives. These refrigerants can be integrated into existing systems as ‘drop in’ refrigerants, which provide a simpler and low cost substitution process to replace environmentally harmful refrigerants such as R410a. R410a is currently a widely used refrigerant in air conditioning systems, but is to be phased out of use under the Kigali Amendment by the late 2040s. Thus to compare the suitability of replacing this refrigerant with environmentally friendly ‘drop in’ alternatives, a preliminary baseline investigation on a mechanical vapor compression chiller with R410a is conducted via performance and exergy indicators. The testing procedure utilized Air Conditioning, Heating and Refrigeration Standard 551/591 which revealed an optimum charge amount of 0.70 kg with a peak performance near 88% of full capacity. The heat exchanger overall heat transfer coefficients showed varying trends, whilst the exergy destruction was as expected highest for the compressor.
