Conscientization Calls: A White Dual Language Educator’s Development of Sociopolitical Consciousness and Commitment to Social Justice

Literature is limited demonstrating how some in-service teachers have developed sociopolitical consciousness and why they commit to social justice. Drawing on interviews, email correspondence, and Facebook postings collected throughout a school year, this article shows the life experiences of one white dual language educator who developed sociopolitical consciousness and a commitment to social justice as a result of what I refer to as conscientization calls based on personal experiences and observed inequities affecting minoritized populations in U.S. and Latin American contexts. This article makes a call to promote educational equity by helping privileged pre-service and in-service teachers by using, as pedagogical tools, conscientization calls they might have received throughout their lives.

A Combination Therapy of pHRE-Egr1-HSV-TK/Anti-CD133McAb-131I/MFH Mediated by FePt Nanoparticles for Liver Cancer Stem Cells

It has been evidenced that liver cancer stem cells (LCSCs) are to blame hepatocellular carcinoma (HCC) occurrence, development, metastasis, and recurrence. Using iron-platinum nanoparticles (FePt-NPs) as a carrier and CD133 antigen as a target, a new strategy to targetly kill LCSCs by integrating HSV-TK suicide gene, 131I nuclide irradiation, and magnetic fluid hyperthermia (MFH) together was designed and investigated in the present study. The results showed that FePt-NPs modified with PEI (PEI-FePt-NPs) could bind with DNA, and the best binding ratio was 1 : 40 (mass ratio). Moreover, DNA binding to PEI-FePt-NPs could refrain from Dnase1 enzyme digestion and could release under certain conditions. LCSCs (CD133+ Huh-7 cells) were transfected with pHRE-Egr1-HSV-TK by PEI-FePt-NPs, and the transfection efficiency was 53.65±3.40%. These data showed a good potential of PEI-FePt-NPs as a gene transfer carrier.131I was labeled with anti-CD133McAb in order to facilitate therapy targeting. The combined intervention of pHRE-Egr1-HSV-TK/anti-CD133McAb-131I/MFH mediated by PEI-FePt-NPs could greatly inhibit LCSCs’ growth and induce cell apoptosis in vitro, significantly higher than any of the individual interventions (p<0.05). This study offers a practicable idea for LCSC treatment, and PEI-FePt-NPs may act as novel nonviral gene vectors and a magnetic induction medium.
A comprehensive review of coconut shell powder composites: Preparation, processing, and characterization

Coconut shell is an agricultural residue, usually disposed of through open burning. Toxic gases have been emitted from the open burning phase and can therefore be detrimental to human health and the environment. Thus, to reduce the risk of pollution, researchers have developed a new technology by using agro-wastes to produce biocomposites. Coconut shell powder (CSP) is a solid nonfood waste, which can be potentially exploited to reduce the usage of synthetic fiber. Coconut shell is also low-cost and low weight material that can be used to reduce the production cost of and fuel consumption for transportation. This review has focused on the research carried out on the CSP loaded into different types of matrices, highlighting the fundamental, mechanical, physical, and thermal properties of CSP composites. This article also provides critical review of the development for CSP composite and the summary of the results presented in the literature, focusing in the properties of CSP with polymeric matrices and the application design for economical products.
Individual event, seasonal and interannual variations in δ18O values of drip water in Maomaotou Big Cave, Guilin, South China, and their implications for palaeoclimatic reconstructions

Accurately interpreting the stable oxygen isotopic composition (δ18O) of cave drip water is critical to the retrieval of palaeoclimatic information based on the δ18O records preserved in speleothem calcite. Substantial cave monitoring data sites of interest can make essential contributions. In this study, six speleothem drip water sites and one pool water site were selected for a five‐year (2013–2017) monitoring of O and H stable isotope ratios in Maomaotou Big Cave, Guilin, South China. The results reveal that the drip water δ18O generally inherits the signals in the precipitation but may lag behind by times ranging from 1 to 6 months. Variations in drip water δ18O are determined by climatic variables operating over several time scales. At the individual storm‐event scale, drip water δ18O is a function of rainfall amount, moisture source δ18O and hydrological processes within the vadose zone. Moisture from nearby Beibu Bay in the northwest of the South China Sea often causes the rainfall and thus drip water to be enriched in 18O at Maomaotou Cave, for example. Seasonally or annually, the higher amounts of precipitation associated with the occurrence of El Niño events (e.g. in 2015/2016) result in more depleted drip water δ18O. On the interannual scale, variations of drip water δ18O are linked to changes in the intensity of the East Asian summer monsoon (EASM), the Southern Oscillation Index (SOI) and the West Pacific Subtropical High (WPSH). An enhanced EASM coupled with La Niña‐like conditions likely results in depleted precipitation δ18O, as does a stronger WPSH that leads to more rainfall. This study illustrates the importance of understanding these complex and varying external environmental conditions that contribute to δ18O changes in drip water, when interpreting the palaeoclimatic information contained in speleothems.
Mechanisms of energy-efficient magnetization switching in a bistable nanowire

Theoretical calculations of optimal control paths minimizing the energy cost of the magnetization reversal in 1D magnetic nanowires are presented. The energy-efficient reversal mechanism is studied as a function of the nanowire length and Gilbert damping parameter. For short nanowires, the optimal reversal mechanism corresponds to a uniform rotation of magnetization. If the length of the wire exceeds a certain critical length defined by the material parameters, switching time and damping, a standing spin wave emerges during magnetization switching. Comparison between the calculated optimal control paths and minimum energy paths reveals that realization of high energy efficiency of switching does not necessarily translate to the minimization of the energy barrier between the target magnetic states.
DEVELOPMENT OF EFFICIENT MICROPROPAGATION SYSTEM FOR E. camaldulensis WITH RESPECT TO AGE OF EXPLANTS

Among the world important hardwood plantation, eucalypts occupied significant position due to their paper pulp, fuel wood and timber. E. camaldulensis being widely distributed and drought tolerant species has the ability to adopt changing rainfall as well as temperature conditions. This property has made it useful in economical and industrial prospects (Butcher et al., 2009; Pinto et al., 2013). Medicinal Eucalyptus oil is largely employed in the preparation of liniments, inhalants, cough syrups, ointments, toothpaste, and pharmaceutical flavouring. The oil obtained from eucalyptus leaves have found various applications in daily life due to their antiseptic, anti-inflammatory and antipyretic properties (Silva et al., 2003; Akin et al., 2007; Cheng et al., 2009). Micropropagation of E. camaldulensis has been documented previously in vitro via direct organogenesis (Yashoda et al., 1997; Kawaoka et al., 2006; Pinto et al., 2013) and indirect organogenesis (Mullins et al., 1997; Ho et al., 1998; Harcourt et al., 2000; Rahim et al., 2003; Dibax et al., 2005; Dibax et al., 2010; Ahad et al., 2014) and indirect somatic embryogenesis (Prakash and Gurumurthi, 2010). Deepika et al. (2011) established in vitro shoot regeneration on MS basal medium supplemented by plant growth hormones (BAP, NAA and TDZ) for various eucalyptus genotypes i.e. E. grandis, E. grandis × E. nitens, E. grandis × E. camaldulensis and E. grandis × E. urophylla. A study on genetic modification of eucalyptus in order to modify the cellulose and hemicellulose biosynthesis to increase the biomass in a short period of time has been reported (Dibax et al., 2010). In comparison to other woody plants this species is very recalcitrant; the problem with eucalyptus is its lower transformation as well as regeneration ability due to heavy leaching of phenolic compounds (Tournier et al., 2003). During Agrobacterium mediated genetic transformation, the transformed tissues usually lose their potential to regenerate and develop plants. Particularly, the failure of well develop rooting systems to initiate roots from transformed shoots show the major obstacle in obtaining whole regenerated transgenic plants. The current study was an attempt to develop a simple, reliable and efficient in vitro regeneration protocol for E. camaldulensis. The explants used were cotyledons, hypocotyls and leaf segments. Effect of age of explants on regeneration potency was also monitored.
Design Development and Evaluation of Perphenazine Solid Lipid Nanoparticles

The main aim of the study was to design Perphenazine solid lipid nanoparticles and to evaluate them. The Perphenazine solid lipid nanoparticles were prepared by the hot homogenization followed by ultrasonication method by using the different lipids (Tristearin, GMS, Compritol) Soya lecithin as stabilizer and Tween-80 used as surfactant. The FTIR test is conducted as the preliminary test, by this test there was no interaction between the drug and lipids. Then nanoparticles were evaluated for particle size, PDI, zeta potential, entrapment efficiency and invitro drug release. The particle size ranged from 53.46 to 518.6 d.nm, PDI ranged from 0.284 to 0.502, zeta potential from -9.83 to -40.96 mV and entrapment efficiency was ranged from 77.45 to 95.38%. The cumulative percentage release from all SLNs varied from 53.35 to 88.74 % after 24hours depending upon the drug and lipid ratio and F2 formulation showed highest drug release i.e., 88.74%. The release kinetic studies showed that the release first order diffusion controlled and the n value (0.47) from the Korsmeyer-Peppa’s model indicated the release mechanism was Quasifickian type.

Sex‐skewed trophic impacts in ephemeral wetlands

Predation can have marked impacts on ecosystem structure, function, and stability. However, quantifications of biotic interactions frequently overlook demographic variabilities within populations, which can modulate interaction strengths, such as sex and reproductive status. Compositional population ratios between males and females, alongside reproductive status, are highly variable temporally in ephemeral aquatic systems, and may profoundly mediate levels of ecological impact and thus stability of trophic groups. In the present study, we apply functional responses (resource intake as a function of resource density) to quantify predatory impacts of adult males, non‐gravid females, and gravid females of the calanoid copepod Lovenula raynerae (Diaptomidae), an abundant ephemeral pond specialist, on larvae of the Culex pipiens (Culicidae) mosquito complex. We then develop a novel metric to forecast population‐level impacts across different population sex ratio scenarios. Lovenula raynerae demonstrated prey population destabilising Type II functional responses irrespective of sex and reproductive status, yet variable functional response magnitudes were found. While male and non‐gravid female copepods exhibited similar functional response maximum feeding rates, gravid female feeding rates were substantially higher, implying higher resource demands for progeny development. Ecological impacts of L. raynerae on lower trophic groups increased markedly where their abundances increased but, crucially, also as population sex ratios became more biased towards gravid female copepods. We demonstrate that population‐level impacts do not only correlate tightly with abundance but may be further modulated by reproductive status variations. Thus, the development of sex‐skewed ratios in favour of gravid females during the hydroperiod probably heightens ecological impacts on lower trophic groups. The implications of these results for prey population stability are discussed in the context of freshwater ecosystems.
Miniaturization of a Dual-Band Wearable Antenna for WBAN Applications

A planar, compact, dual-band antenna on a semiflexible substrate is proposed for 2.45/5.85 GHz wireless body-area network applications. The proposed antenna is comprised of an I-shaped monopole embedded with an inverted L-shaped slit and an inductive meander line on the front side of the substrate, which excites the higher resonant mode at 5.85 GHz. On the backside, an inverted U-shaped stripline embedded with another inductive meander line is attached to the ground plane to excite the lower resonant mode at 2.45 GHz. The key to the miniaturization procedure is increasing the inductance and the capacitance by loading the inductive meander lines and slit line. The overall size of the proposed antenna is 0. 15λ × 0. 1λ × 0. 004λ at 2.45 GHz. The measured results of the proposed antenna show the impedance bandwidths of 5.7% (2.4–2.54 GHz) and 3.78% (5.72–5.94 GHz) and the maximum peak gains of 2.1 dBi and 3.5 dBi, respectively. The simulated specific absorption rate values satisfy both the U.S. and EUR standards of under 1 g average and under 10 g average, respectively.
The role of the Mental Health Tribunal in setting duration of compulsory treatment in Victoria

This article explores the role of the Mental Health Tribunal (the Tribunal) in setting duration of compulsory treatment orders under the Mental Health Act 2014 (Vic) (the MH Act) using qualitative analysis of data obtained by a Tribunal working group. It explores the extent to which there is a difference between the duration of treatment orders requested by treating teams and those made by the Tribunal, as well as the factors the Tribunal takes into account in setting a different duration. Results reveal the Tribunal made a treatment order of different (mostly shorter) duration in one out of five hearings. In these cases, two out of four factors identified by the working group were dominant influences: (1) ensuring congruence with the principles of the MH Act; and (2) information presented by one or more participants at the hearing. There were also high levels of attendance from either the patient, their support person or their legal representative when the Tribunal made a treatment order of different duration. This suggests participation by patients and support people at hearings provides the Tribunal with the information it needs to consider the principles under the MH Act meaningfully when exercising its discretion to determine the duration of compulsory treatment orders.
Genetic diversity and population connectivity of the sea urchin Tripneustes gratilla along the South African coast

The collector sea urchin Tripneustes gratilla has been identified as a species with potential for aquaculture production in South Africa. The species’ roe is considered a culinary delicacy in Asia and Europe. However, T. gratilla remains genetically uncharacterised in South Africa. Therefore, the purpose of this study was to provide baseline genetic information consisting of estimates of genetic diversity and population stratification, which may aid in future sustainable use of this urchin resource. A total of 22 species-specific microsatellite markers were used for the genetic characterisation of T. gratilla samples from along the South African coast, at Haga Haga, Coffee Bay, Hibberdene, Ballito Bay and Sodwana Bay. A moderate level of genetic diversity was observed, with an average number of alleles of 7.89 and an average effective number of alleles of 6.57, as well as an average observed heterozygosity of 0.55. Population differentiation tests suggest that the geographically representative samples form part of a single, large interbreeding population, with a global Fst estimate of 0.02 (p > 0.05). This finding is likely explained by high levels of gene flow between these locations caused by extensive larval dispersal during the planktonic larval stage. The panmixia observed within these natural populations of T. gratilla indicate that they could be managed as a single genetic stock.
Immobilization of Cellulolytic Enzymes in Mesostructured Silica Materials

Mesostructured silica nanoparticles offer a unique opportunity in the field of biocatalysis thanks to their outstanding properties. The tunable pore size in the range of mesopores allows for immobilizing bulky enzyme molecules. The large surface area improves the catalytic efficiency by increasing enzyme loading and finely dispersing the biocatalyst molecules. The easily tunable pore morphology allows for creating a proper environment to host an enzyme. The confining effect of mesopores can improve the enzyme stability and its resistance to extreme pH and temperatures. Benefits also arise from other peculiarities of nanoparticles such as Brownian motion and easy dispersion. Fossil fuel depletion and environmental pollution have led to the need for alternative sustainable and renewable energy sources such as biofuels. In this context, lignocellulosic biomass has been considered as a strategic fuel source. Cellulases are a class of hydrolytic enzymes that convert cellulose into fermentable sugars. This review is intended to survey the immobilization of cellulolytic enzymes (cellulases and β-glucosidase) onto mesoporous silica nanoparticles and their catalytic performance, with the aim to give a contribution to the urgent action required against climate change and its impacts, by biorefineries’ development.

CORRELATION BETWEEN TSH, T3, T4 AND HISTOLOGICAL TYPES OF THYROID CARCINOMA

Thyroid carcinoma is a malignancy of the thyroid gland derived from follicular or parafollicular cells. Thyroid carcinoma is the most common endocrine gland malignancy and accounts for approximately 1% of all malignancies. Thyroid carcinoma ranked ninth of 10 most common carcinomas in Indonesia. It may occur at any age but is usually diagnosed between the 3rd and 6th decade. The incidence is three or four times higher in females than in males. Based on histological features thyroid carcinoma is classified into four major types: papillary, follicular, anaplastic and medullary carcinoma. Thyroid Stimulating Hormone (TSH), Triiodothyronine (T3), Thyroxine (T4) are thyroid gland hormones. Low T3 and T4 accompanied with high TSH levels are associated with malignancy in thyroid carcinoma. This study aimed to determine the correlation between TSH, T3, T4 hormone levels, and histological type of thyroid carcinoma at the Adam Malik Hospital Medan between 2013 and 2015. The study was a cross-sectional analytical study. The sample was be obtained using consecutive sampling method. Data were collected from medical records of thyroid carcinoma patients that had undergone pathological examination and thyroid function test at the Adam Malik Hospital Medan between 2013 and 2015. Based on the Chi-Square analysis, there was a significant difference between T3 hormone level with the histopathological type of thyroid carcinoma (p<0.001), however it did not apply to the level of T4 (p = 0.120) and TSH (p = 0.328).
Timing and Duration of Gbx2 Expression Delineates Thalamocortical and Dopaminergic Medial Forebrain Bundle Circuitry

Gene expression is a dynamic process, which is highly coordinated during development to ensure the proper allocation and identity of neuronal cell types within the brain. Equally important during neurodevelopment is how cohorts of neurons establish axonal projections that innervate terminal target sites. We sought to bridge the temporal dynamics of gene expression, within a specific genetic lineage, to the establishment of neuronal circuits derived from cohorts of the lineage-specific progenitors. A central goal was to be able to accomplish genetic inducible circuit mapping non-invasively and with commonly available CreER/loxP technology. Specifically, we genetically marked thalamic neuron progenitors that expressed the transcription factor Gbx2 at an early embryonic stage and tracked the formation of lineage-derived thalamocortical axons during embryogenesis. We then assessed the neural circuitry at an early postnatal stage. We show that the temporal specificity of lineage marking provides a high degree of clarity for following neural circuit development. We also determined that the onset and duration of gene expression can delineate subsets of neural circuits derived from a common lineage. For example, we uncovered a novel contribution of Gbx2-expressing progenitors to midbrain dopamine neurons and dopaminergic axons of the medial forebrain bundle. We anticipate that this system can be instructive in elucidating changes in neural circuit development in both normal development and in mutant mice in which neural circuit formation is altered.
