Annotated checklist of the herpetofauna of the Pilliga Forest in northern inland New South Wales, Australia for the period January 2006 - January 2018
Authors: Murphy Michael J. 
Published: May 2022

ABSTRACT
The Pilliga Forest is one of the largest surviving woodland remnants on the New South Wales western slopes in inland eastern Australia. Collation of personal observations by a resident herpetologist working in the Pilliga Forest over a 12-year period identified 18 frog species and 49 reptile species. One additional reptile species was identified from museum specimen records, and unconfirmed reports of another one frog and seven reptile species are also noted. This paper provides the most comprehensive published account of the herpetofauna of the Pilliga Forest to date, and illustrates the value of observations over an extended period. Comparison with other locations across western New South Wales highlights the high species richness of the Pilliga Forest for both frogs and reptiles. This is in part a function of its location in a biogeographic overlap zone between eastern, western and northern faunal assemblages. Species of particular conservation concern found in the Pilliga Forest include the threatened Hoplocephalus bitorquatus, near-threatened Pseudophryne bibronii and declining woodland reptiles such as Ctenotus allotropis, Diporiphora nobbi, Morelia spilota metcalfei, Acanthophis antarcticus, Brachyurophis australis and Vermicella annulata.

Blood transfusion is a substitute therapy which consists to administered blood or one of its components to one or more sick person. hematological components retain their stability if the cold chain is maintained between 2 and 6°C. essential for good transfusion performance. The aim of this work was to evaluate the stability of haemogram parameters under the influence of cold chain on whole blood bags seronegative from infections transmissible by blood transfusion (ITT).
Methodology: A cohort of 200 blood collected into the citrate phosphate dextrose adenine (CPDA) blood bag collected consecutively at the blood transfusion center of the Douala General Hospital constituted the population of the study conducted from March 1st to September 30th, 2018. 5ml of this blood from the donor’s blood bag was collected into a dry tube (for the blood count using URIT 3000 Plus machine) and the rest was stored in a BIOBASE brand refrigerator at a temperature between 2 and 6. On the day of delivery, a second sample was taken by section of the tubing of the bag for the analysis of a second haemogram of the same blood bags. Temperature, refrigerator opening frequency and blood were collected every day. Data analysis was done using by SPSS 20.0 for Windows software. The results were considered significant at p˂0.05.
Results: The storage temperature significantly (p˂0.05) decrease the rate of leukocytes, erythrocytes and hemoglobin. When the shelf life and the frequency of opening the refrigerator increased, hemoglobin, hematocrit, MCV and lymphocyte decreased significantly while leukocyte, MCHC, thrombocytes and granulocytes increase significantly.
Conclusion: This study showed that, the decrease in leukocytes, red blood cells and hemoglobin levels was significantly related to shelf life and frequency of opening the refrigerator. Knowledge on this variation could be very useful in the selection of refrigerated blood or pint and the efficiency of transfusion.

This study is aimed at investigating the effects of tamoxifen on lipid profile. In order to achieve this, tamoxifen was administered once daily intraperitoneally to the female rats at a dose of 2.07mg/kg body weight for 1 and 2 weeks, while a group of rats was allowed to recover for a week after 2 weeks of tamoxifen administration. Rats in the control group were similarly treated but were given corn oil instead of the drug. Tamoxifen administration caused perturbations of major lipids in the animals. Administration of tamoxifen for 1 week lowered cholesterol and triglycerides levels in the plasma by 23.63 % and 39.74 % respectively and in the low density lipoproteins and very low density lipoproteins (LDL+VLDL) by 79.72 % and 67.59 % respectively, while it increased high density lipoproteins (HDL) cholesterol by 3.44 fold. In the tissues, tamoxifen administration for 2 weeks did not significantly affect cholesterol and triglycerides levels but phospholipid levels in the liver, kidney and heart were lowered by 52.38 %, 42.98 % and 73.82 % respectively, while phospholipidosis was the hallmark of its effect in the spleen. The result of our study affirmed that tamoxifen exerts a favourable effect on lipid profile. The hypocholesterolemic and hypotriglyceridesmia effects of tamoxifen observed in this study may partially explain the decrease in coronary heart disease related mortality seen in patients receiving tamoxifen treatment.

Published: May 2022

Aims: This study evaluated the effect of the aqueous fraction of Justicia secunda Vahl leaves on selected inflammatory markers Tumor necrosis factor alpha (TNF-α), nuclear factor–kappa B (NF-κB), interleukin-6 (IL-6) and cyclooxygenase-2 (COX-2) and its possible mechanism of action.
Study Design: J. secunda aqueous leaf fraction (JSALF) was tested on carrageenan, arachidonic and Complete Freund’s Adjuvant (CFA) induced rat paw inflammation models, respectively.
Methodology: Ninety male albino rats (Wistar strain) were randomly distributed into 6 groups of 5 rats each. Group I: normal, administered with 1 mL NaCl, Group II: untreated control, no treatment, Group III: administered with 10 mg/kg body weight (b.wt.) diclofenac sodium (reference drug), Group IV, V, and VI: administered with 200, 400 and 600 mg/kg b.wt. J. secunda leaf aqueous fraction (JSALF), respectively. TNF-α, NF-κB, IL-6 and COX-2 levels were analyzed using enzyme-linked immunosorbent assays (ELISA). Gas Chromatography-Mass Spectrometry (GC-MS) analysis was carried out.
Results: JSALF treated animals had significantly (P < .05) suppressed carrageenan, arachidonic and CFA-induced paw edema when compared with untreated control animals. Serum levels of TNF-α, NF-κB, IL-6 and COX-2 were significantly reduced (P < .05) in JSALF-treated animals. GC-MS detected 10 suspected anti-inflammatory compounds.
Conclusion: Findings from this study indicate that J. secunda aqueous leaf fraction substantially suppressed pro-inflammatory mediators and COX-2 pathways in arthritic rats which justifies its folkloric use in the management of inflammatory diseases.

AbstractKnowledge graphs (KGs) are a novel paradigm for the representation, retrieval, and integration of data from highly heterogeneous sources. Within just a few years, KGs and their supporting technologies have become a core component of modern search engines, intelligent personal assistants, business intelligence, and so on. Interestingly, despite large‐scale data availability, they have yet to be as successful in the realm of environmental data and environmental intelligence. In this paper, we will explain why spatial data require special treatment, and how and when to semantically lift environmental data to a KG. We will present our KnowWhereGraph that contains a wide range of integrated datasets at the human–environment interface, introduce our application areas, and discuss geospatial enrichment services on top of our graph. Jointly, the graph and services will provide answers to questions such as “what is here,” “what happened here before,” and “how does this region compare to …” for any region on earth within seconds.

AbstractPurposeAn accurate and reliable target volume delineation is critical for the safe and successful radiotherapy. The purpose of this study is to develop new 2D and 3D automatic segmentation models based on RefineNet for clinical target volume (CTV) and organs at risk (OARs) for postoperative cervical cancer based on computed tomography (CT) images.MethodsA 2D RefineNet and 3D RefineNetPlus3D were adapted and built to automatically segment CTVs and OARs on a total of 44 222 CT slices of 313 patients with stage I–III cervical cancer. Fully convolutional networks (FCNs), U‐Net, context encoder network (CE‐Net), UNet3D, and ResUNet3D were also trained and tested with randomly divided training and validation sets, respectively. The performances of these automatic segmentation models were evaluated by Dice similarity coefficient (DSC), Jaccard similarity coefficient, and average symmetric surface distance when comparing them with manual segmentations with the test data.ResultsThe DSC for RefineNet, FCN, U‐Net, CE‐Net, UNet3D, ResUNet3D, and RefineNet3D were 0.82, 0.80, 0.82, 0.81, 0.80, 0.81, and 0.82 with a mean contouring time of 3.2, 3.4, 8.2, 3.9, 9.8, 11.4, and 6.4 s, respectively. The generated RefineNetPlus3D demonstrated a good performance in the automatic segmentation of bladder, small intestine, rectum, right and left femoral heads with a DSC of 0.97, 0.95, 091, 0.98, and 0.98, respectively, with a mean computation time of 6.6 s.ConclusionsThe newly adapted RefineNet and developed RefineNetPlus3D were promising automatic segmentation models with accurate and clinically acceptable CTV and OARs for cervical cancer patients in postoperative radiotherapy.

AbstractPurposeTo better meet clinical needs and facilitate optimal treatment planning, we added two new electron energy beams (7 and 11 MeV) to two Varian TrueBeam linacs.MethodsWe worked with the vendor to create two additional customized electron energies without hardware modifications. For each beam, we set the bending magnet current and then optimized other beam‐specific parameters to achieve depths of 50% ionization (I50) of 2.9 cm for 7 MeV and 4.2 cm for the 11 MeV beam with the 15 × 15 cm2 cone at 100 cm source‐to‐surface distance (SSD) by using an ionization chamber profiler (ICP) with a double‐wedge (DW) phantom. Beams were steered and balanced to optimize symmetry with the ICP. After all parameters were set, full commissioning was done including measuring beam profiles, percent depth doses (PDDs), output factors (OFs) at standard, and extended SSDs. Measured data were compared between the two linacs and against the values calculated by our RayStation treatment planning system (TPS) following Medical Physics Practice Guideline 5.a (MPPG 5.a) guidelines.ResultsThe I50 values initially determined with the ICP/DW agreed with those from a PDD‐scanned in‐water phantom within 0.2 mm for the 7 and 11 MeV on both linacs. Comparison of the beam characteristics from the two linacs indicated that flatness and symmetry agreed within 0.4%, and point‐by‐point differences in PDD were within 0.01% ± 0.3% for the 7 MeV and 0.01% ± 0.3% for the 11 MeV. The OF ratios between the two linacs were 1.000 ± 0.007 for the 7 MeV and 1.004 ± 0.007 for the 11 MeV. Agreement between TPS‐calculated outputs and measurements were −0.1% ± 1.0% for the 7 MeV and 0.2% ± 0.8% for the 11 MeV. All other parameters met the MPPG 5.a's 3%/3‐mm criteria.ConclusionWe were able to add two new beam energies with no hardware modifications. Tuning of the new beams was facilitated by the ICP/DW system allowing us to have the procedures done in a few hours and achieve highly consistent results across two linacs.PACS numbers: 87.55.Qr, 87.56.Fc

AbstractPenetration of cell membrane at micro/nano‐scale with untethered probe is of great scientific significance, yet still challenging. Here, a carbon nanocoil based magnetic nanorobot, which can precisely target single cell and perform cell membrane penetration, is reported. The nanorobots are as‐synthesized by chemical vapor deposition with high yield, followed by physical deposition of Ni and Au nanofilms. Rotating electromagnetic fields are used to steer the nanorobots to navigate following any pre‐designed path. The helical nanorobots can realize mechanical perforation of the plasma membrane and even nuclear envelope with precise position at the subcellular level. With the aid of the externally deposited Au nanofilm, surface enhanced Raman scattering bio‐sensing signals can be collected from cellular plasma and nucleus. Furthermore, the nanorobots demonstrate capability of efficient photothermal therapy against targeted cancer cells and serve as an integrated theranostic platform, providing promising prospects in future precision medicine.

Published: May 2022

AbstractDeoxyribonucleic acid (DNA) represents an important class of molecular building blocks for the assembly of supramolecular functional systems primarily due to its molecular recognition capability and sequence programmability. Eventually, DNA‐based nanostructures are assembled in a way that their states remain at the thermodynamic minimum of the energy. However, active life‐like functions and their interactive adaption require the integration of energy away from thermodynamic equilibrium. The construction of DNA‐based artificial systems was often inspired by the naturally occurring dissipative assembly processes, which leads to the consumption of energy to maintain the thermodynamically non‐equilibrium state. In this review, the recent progress of the fabrications and properties of DNA‐based dissipative assembly systems toward nanoarchitectonics is summarized. It focuses on the principle of dissipative assembly and shows some pioneering examples of DNA‐based dissipative assembly systems. The latest corresponding perspectives are also proposed.

AbstractThe scientific effort to control the interaction between light and matter has grown exponentially in the last 2 decades. This growth has been aided by the development of scientific and technological tools enabling the manipulation of light at deeply sub‐wavelength scales, unlocking a large variety of novel phenomena spanning traditionally distant research areas. Here, the role of chirality in light–matter interactions is reviewed by providing a broad overview of its properties, materials, and applications. A perspective on future developments is highlighted, including the growing role of machine learning in designing advanced chiroptical materials to enhance and control light–matter interactions across several scales.

Published: May 2022

AbstractCost‐effective adsorbent materials with high Pb(II) removal efficiency and selectivity are considered necessary for successfully removing Pb(II) contamination from drinking water because of their high‐level toxicity and the ultra‐low safe level of ≤10 ppb in water. This study demonstrates the synthesis and the ultrafast Pb(II) removal capability of a partially reduced graphene oxide‐nano‐molybdenum disulfide composite (prGO‐MoS2). The prGO‐MoS2 exhibits thin sheets of prGO covered more or less uniformly with nano‐MoS2, and the open architecture gives enhanced accessibility to the S2– and oxygen moieties present in prGO‐MoS2. A single treatment of contaminated water samples with prGO‐MoS2 rapidly decreases the concentration of Pb(II) from 10 000 ppb to 0.8642 ppb within ≤3 min with an efficiency of ≥99.99% (4 log reduction value) at a V/m ratio of 2000 mL mg−1. Among the reported materials for Pb(II) removal, prGO‐MoS2 exhibits the fastest removal speed (≤3 min) and the second‐highest adsorption capacity (762 mg g−1), and the highest distribution coefficient (Kd = 6.0 × 108 mL g−1). Here, the high removal performance of Pb(II) by prGO‐MoS2 is delineated based on affinity between Pb(II) and S2− and oxygen moieties, electrochemistry, and the unique structural characteristics.

Published: May 2022

AbstractDeveloping a high‐performance photocatalyst is important for realizing efficient photocatalytic H2O2 generation. Herein, a novel step‐scheme (S‐scheme) heterojunction photocatalyst C3N4/PDA (CNP) comprised of ultrathin g‐C3N4 (U‐CN) and polydopamine (PDA) is constructed by in situ self‐polymerization. The optimal photocatalyst presents an excellent H2O2 production rate of 3801.25 µmol g−1 h−1 under light irradiation, which is about 2 and 11 times higher than that of pure U‐CN and PDA, respectively, and exceeds most of the reported C3N4‐based photocatalysts. The improvement of photocatalytic activity is ascribed to the synergistic effect of improved light absorption and promoted charge separation and transfer induced by the S‐scheme heterojunction. In situ irradiated X‐ray photoelectron spectroscopy (ISI‐XPS) reveals that the charge transfer route matches the S‐scheme mechanism. Rotating disk electrode (RDE) measurements and electron spin resonance (ESR) spectroscopy verify that H2O2 is produced by a two‐step one‐electron process. This work highlights a promising method to construct high‐performance S‐scheme heterojunction photocatalysts through the hybridization of PDA and C3N4.

AbstractEngineering of the dipole and the symmetry of materials plays an important role in fundamental research and technical applications. Here, a novel morphological manipulation strategy to engineer the dipole orientation and symmetry of 2D layered materials by integrating them with 1D nanowires (NWs) is reported. This 2D InSe –1D AlGaAs NW heterostructure example shows that the in‐plane dipole moments in InSe can be engineered in the mixed‐dimensional heterostructure to significantly enhance linear and nonlinear optical responses (e.g., photoluminescence, Raman, and second harmonic generation) with an enhancement factor of up to ≈12. Further, the 1D NW can break the threefold rotational symmetry of 2D InSe, leading to a strong optical anisotropy of up to ≈65%. These results of engineering dipole orientation and symmetry breaking with the mixed‐dimensional heterostructures open a new path for photonic and optoelectronic applications.

AbstractThe quest for advanced superionic materials requires understanding their complex atomic dynamics, but detailed studies of the interplay between lattice vibrations and ionic diffusion remain scarce. Here inelastic and quasielastic neutron scattering measurements in the superionic argyrodite Cu7PSe6 are reported, combined with molecular dynamics (MD) based on ab initio and machine‐learned potentials, providing critical insights into the atomistic mechanisms underlying fast ion conduction. The results reveal how long‐range Cu diffusion is limited by intercluster hopping, controlled by selective anharmonic phonons of the crystalline framework. Further, the Green–Kubo simulations reproduce the ultralow lattice thermal conductivity and identify contributions from mobile ions, phonons, and their cross‐correlations. The mode resolved analysis shows that the thermal conductivity is dominated by low‐energy acoustic phonon modes of the overall crystal framework. The analysis of mode‐resolved spectral functions further show that vibrational modes with significant Cu contributions are strongly damped, corresponding to the breakdown of associated phonon quasiparticles. These results highlight the importance of strongly anharmonic effects in superionic systems, in which the traditional quasiharmonic phonon picture is insufficient, and pave the way toward combining machine‐learning accelerated simulations with neutron scattering experiments to rationalize the complex atomic dynamics underlying ionic and thermal transport.
