Air dengan kualitas yang baik merupakan kebutuhan makhluk hidup yang harus dipenuhi demi keberlangsungan hidupnya. Sumber air untuk bahan baku industri air mineral diantaranya berasal dari air tanah dan air permukaan. Kualitas air tanah yang diambil dari Kecamatan Anjongan, Kabupaten Mempawah, Kalimantan Barat yang digunakan sebagai sumber air tidak memenuhi persyaratan nilai keasaman (pH) sesuai Peraturan Menteri Kesehatan Nomor 416/MENKES/IX/1990 sebagaimana telah dilakukan pengujian sumber air tersebut oleh salah satu perusahaan air mineral di Kalimantan Barat sebagai syarat untuk pengurusan SPPT SNI. Tujuan penelitian ini adalah meningkatkan nilai pH air sumber sehingga layak digunakan sebagai air baku. Tiga jenis bahan penyaring yaitu pasir kuarsa, pasir mangan dan karbon aktif digunakan untuk menaikkan nilai pH. Hasil penelitian menunjukkan bahwa air yang yang disaring menggunakan karbon aktif mengalami peningkatan nilai pH dengan persentase peningkatan 18,7 %, menaikkan pH dari 5,68 menjadi 6,74 sehinnga memenuhi standar mutu (pH 6,5-9), sedangkan penyaringan dengan pasir mangan dan pasir kuarsa, hasil kenaikan pH nya masih belum memenuhi standar. Pemerintah daerah dapat menyampaikan solusi peningkatan kualitas keasaman air baku ke perusahaan-perusahaan lainnya yang memiliki kendala yang sama di lapangan.

Os linfomas são neoplasias de origem hematopoiética originados a partir da proliferação de linfócitos. A formação destas neoplasias se dá principalmente em baço, linfonodos e fígado, entretanto podem se desenvolver em qualquer órgão devido as concentrações de linfócitos circulantes. Na Medicina Veterinária, são classificados quanto a sua distribuição anatômica, morfologia celular e organização histológica (MORRIS & DOBSON,2001). Tumores hematopoiéticos estão entre as grandes causas de mortalidade e morbidade em animais de laboratório, sendo observados em camundongos de quase todas as linhagens, principalmente nas consanguíneas. Dentre os linfomas espontâneos em camundongos, a forma mais relatada é o Linfoma de Células B Folicular, envolvendo principalmente o baço, placas de Peyer e linfonodos mesentéricos (PERCY & BARTHOLD, 2007). Relata-se os aspectos clínicos, macroscópicos e microscópicos de um caso de linfoma espontâneo em camundongo (Mus musculus) diagnosticado pelo Laboratório de Patologia Veterinária (LPV) da Universidade Federal do Paraná (UFPR), Setor Palotina. Foi atendido no Hospital Veterinário da UFPR, Setor Palotina, um camundongo, fêmea, de um ano de idade apresentando dispneia e aumento de volume abdominal, após a avaliação física o paciente foi encaminhado para avaliação ultrassonográfica de abdômen evidenciando deposito de gordura abdominal abundante e enterite. Após a liberação do paciente, o mesmo evoluiu para óbito sendo encaminhado para necropsia no LPV. Macroscopicamente, observou-se mucosas oculares pálidas, acentuada esplenomegalia, e fígado difuso e acentuadamente amarelado, pulmão inflado moderadamente hiperemico além de linfoadenomegalia de linfonodo mesentérico. Na avaliação histológica dos tecidos hepático, esplênico, pulmonar, renal, ovariano, cardíaco e de linfonodo mesentérico haviam áreas de proliferação neoplásica de células redondas, altamente celular, mal demarcada, não encapsulada e infiltrativa. As células eram arranjadas em mantos de células bem agrupadas sobre estroma fibrovascular escasso. As mesmas eram arredondadas a poligonais com limites celulares distintos; o citoplasma era escasso, basofílico, homogêneo; o núcleo redondo, paracentral, cromatina frouxa e um a dois nucléolos evidentes, por vezes o núcleo era irregular, com aspecto multilobular e cromatina condensada (flower cells). Havia anisocitose e anisocariose acentuada e oito mitoses por cga. Notou-se moderada quantidade das células neoplásicas nos vasos sanguíneos (êmbolos neoplásicos). Os achados histopatológicos associados as alterações clinicas do paciente foram compatíveis com o diagnóstico de linfoma, sugerindo-se linfoma de grandes células B do mediastino ou Linfoma anaplasico em decorrência da presença de flower cells. A histopatologia é uma ferramenta diagnóstica de extrema importância para melhor conduta terapêutica.

Published: December 2020

AbstractKirigami structures provide a promising approach to transform flat films into 3D complex structures that are difficult to achieve by conventional fabrication approaches. By designing the cutting geometry, it is shown that distinct buckling‐induced out‐of‐plane configurations can be obtained, separated by a sharp transition characterized by a critical geometric dimension of the structures. In situ electron microscopy experiments reveal the effect of the ratio between the in‐plane cut size and film thickness on out‐of‐plane configurations. Moreover, geometrically nonlinear finite element analyses (FEA) accurately predict the out‐of‐plane modes measured experimentally, their transition as a function of cut geometry, and provide the stress–strain response of the kirigami structures. The combined computational–experimental approach and results reported here represent a step forward in the characterization of thin films experiencing buckling‐induced out‐of‐plane shape transformations and provide a path to control 3D configurations of micro‐ and nanoscale buckling‐induced kirigami structures. The out‐of‐plane configurations promise great utility in the creation of micro‐ and nanoscale systems that can harness such structural behavior, such as optical scanning micromirrors, novel actuators, and nanorobotics. This work is of particular significance as the kirigami dimensions approach the sub‐micrometer scale which is challenging to achieve with conventional micro‐electromechanical system technologies.

AbstractIncreasing the energy density of lithium‐ion batteries requires the discovery of new electrode materials capable of achieving very high areal capacity. Here, liquid phase exfoliation is used to produce nanosheets of SnP3, a 2D material with extremely high theoretical capacity of 1670 mAh g−1. These nanosheets can be fabricated into solution‐processed thin films for use as lithium storing anodes. To maximize their performance, carbon nanotubes are incorporated into the electrodes to simultaneously enhance conductivity and toughness. As a result, electrodes of thickness >300 µm can be produced, which display active‐mass‐normalized capacities (≈1657 mAh g−1Active) very close to the theoretical value. These materials show maximum specific (≈1250 mAh g−1Electrode) and areal (>20 mAh cm−2) capacities, which are at the state‐of‐the‐art for 2D‐based electrodes, coupled with good rate performance and stability. In combination with commercial cathode materials, full‐cells are fabricated with areal capacities of ≈29 mAh cm−2 and near‐record energy densities approaching 1000 Wh L−1.

AbstractDeveloping high performance n‐type thermoelectric (TE) materials is fundamentally important for developing high efficiency TE devices. AgBiSe2, which reveals superior n‐type TE performance in a cubic phase, crystallizes in a hexagonal phase at room temperature, and typically, undergoes phase transitions to a cubic phase at a temperature above 580 K. Here, for the first time, through entropy optimization with lead‐selenides (≥9.9 mol%), the high‐temperature cubic phase of AgBiSe2 is stabilized from 300 to 800 K. Furthermore, the AgBiSe2‐PbSe pseudo‐binary diagram is established. The resultant alloys with optimized entropy possess unique local distorted cubic lattices, which contribute low lattice thermal conductivity approaching 0.3 W m−1 K−1 in extended operating temperature range. Consequently, a peak figure of merit zT value of ≈0.8 at 800 K and a record‐high average zT value of 0.42 for n‐type I‐V‐VI2 compounds are attained in pure phase cubic n‐type (AgBiSe2)1−x(PbSe)x solid solutions. These results pave the way for developing new TE materials via entropy engineering.

Published: December 2020

AbstractThe popularity of wearable smart electronic gadgets, such as smartphones, smartwatches, and medical sensors, is inhibited by their limited operation lifetime due to the lack of a sustainable self‐charging power supply. This constraint can be overcome by developing a flexible, self‐charging photocapacitor that can synchronously harvest and store energy. Here, ultrathin, all‐printed, and metal‐embedded transparent conducting electrodes (ME‐TCEs) are designed for the fabrication of large‐area, flexible organic solar cells (F‐OSCs) and flexible supercapacitors (F‐SCs). Stripe‐shaped F‐OSCs (SF‐OSCs) and F‐SCs (SF‐SCs) are obtained via slitting the as‐fabricated F‐OSCs and F‐SCs with a surgical scalpel, respectively. The SF‐OSCs and SF‐SCs fully retain their performance after slitting, achieving a power conversion efficiency of ≈6.43% and areal capacitance of ≈52 mF cm−2, respectively. Furthermore, photocapacitor fibers are obtained by vertically stacking one SF‐OSC and seven SF‐SCs. Each fiber is fully encapsulated using UV‐curable resin. When woven into a textile, the photocapacitor module (2 series × 4 parallel connections) is able to charge up to a voltage of 3.2 V in 5 min under one‐sun illumination. The photoelectric‐conversion‐and‐storage efficiency (η) of the photocapacitor module is 4.94%. The highly tailorable, mechanically robust photocapacitor demonstrated herein can be a secondary, self‐sustainable power supply for futuristic wearable applications.

AbstractAmmonium persulfate‐initiated cyclopolymerization of maleic acid (HO2CC=CCO2H) (MA) with diallylamine (–NR2, R = CH2 = CH‐CH2) derivatives (DADs): R2NH+CH2CO2− (I), R2NCH2CO2−Na+ (II), R2NCH2CO2Et (III), R2NH+(CH2)3CO2− (IV), R2N(CH2)3CO2Et (V), R2NH+(CH2)3SO3− (VI) and R2N(CH2)3SO3−Na+ (VII) gave a series of new pH‐responsive alternate copolymers: –[(DAD‐alt‐MA)]n– VIII‐XIV, respectively. Homopolymers XV and XVI of the corresponding monomers IV and V·HCl were also synthesized. The evaluation of the synthesized polymers as potential antiscalants in reverse osmosis (RO) plants was examined. An effective scale inhibitor must arrest the formation of scale for a residence time (≈15 min) of feed water in the RO chamber. R2NH+(CH2)3CO2− (IV)‐alt‐MA copolymer XI at a concentration of 5 ppm imparted 99% scale inhibition for 360 min, while at 2.5 and 1 ppm concentrations, the CaSO4 scale inhibitions were found to be 99% and ≈ 100% during 120 and 20 min, respectively, at 40°C. Homopolymers XV and XVI, at a 20‐ppm concentration, demonstrated ≈ 95% efficiency in inhibiting mild steel corrosion in 1 M HCl. In some important oilfield applications, requirement of simultaneous scale and corrosion inhibition make these polymers potential candidates for desalination and oilfield applications.

Published: December 2020

AbstractPhytoestrogens can control high‐fat diet‐induced hypothalamic inflammation that is associated with severe consequences, including obesity, type 2 diabetes, cardiovascular and neurodegenerative diseases. However, the phytoestrogen anti‐neuroinflammatory action is poorly understood. In this study, we explored the neuroprotection mediated by daidzein in hypothalamic neurons by using a membrane‐based model of obesity‐related neuroinflammation. To test the daidzein therapeutic potential a biohybrid membrane system, consisting of hfHypo GnRH‐neurons in culture on PLGA membranes, was set up. It served as reliable in vitro tool capable to recapitulate the in vivo structure and function of GnRH hypothalamic tissue. Our findings highlighted the neuroprotective role of daidzein, being able to counteract the palmitate induced neuroinflammation. Daidzein protected hfHypo GnRH cells by downregulating cell death, proinflammatory processes, oxidative stress, and apoptosis. It also restored the proper cell morphology and functionality through a mechanism which probably involves the activation of ERβ and GPR30 receptors along with the expression of GnRH peptide and KISS1R.
Web‐based imaging viewer for real‐color volumetric reconstruction of human visible project and DICOM datasets
Authors: Borgbjerg Jens 
Published: December 2020

AbstractAnatomy remains a cornerstone of medical education. It is vital that students achieve a robust understanding of the spatial relationships between anatomical structures in three dimensions. Volumetric medical imaging studies and true‐color cryosectional three‐dimensional images of visible human datasets are useful for enhancing anatomy education. However, the software systems available for viewing these datasets have important limitations. A web‐based application called Mulrecon Color, which can overcome a number of those limitations, is introduced. Mulrecon Color enables volumetric medical and full color cryosectional datasets to be explored without requiring installation, and can therefore be used on a broad range of desktop, mobile, and even virtual reality devices. The web‐based application has an interface that resembles a DICOM viewer used in radiological practice, and can be used both in anatomical labs and off campus for self‐study. The Mulrecon Color application is released as an open source tool. It can be retrieved at a project website where sample datasets are also available.

AbstractBackgroundDistant metastasis (DM) is relatively rare in superficial gastric cancer (SGC), especially in patients without lymph node metastasis. This study aimed to explore the main clinical risk factors for DM in patients with superficial gastric cancer‐no lymph node metastasis (SGC‐NLNM) and the prognostic factors for patients with DM.MethodsRecords of patients with SGC‐NLNM between 2004 and 2015 were collected from the public Surveillance, Epidemiology, and End Results (SEER) database. Both univariate and multivariate logistic regressions were performed to analyze the clinical risk factors for DM. The Kaplan–Meier method and Cox regression model were used to identify prognostic factors for patients with DM. A nomogram was built based on multivariate logistic regression and evaluated by the C‐index, the calibration, and the area under the receiver operating characteristic curve (AUC).ResultsWe developed and validated a nomogram to predict DM in patients with SGC‐NLNM, showing that race, age, primary site, depth, size, and grade were independent risk factors. The built nomogram had a good discriminatory performance, with a C‐index of 0.836 (95% confidence interval [CI]: 0.813–0.859). Calibration plots showed that the predicted DM probability was identical to the actual observations in both the training and validation sets. AUC was 0.846 (95% CI: 0.820–0.871) and 0.801 (95% CI: 0.751–0.850) in the training and validation sets, respectively. The results of the survival analysis revealed that surgery (hazard ratio [HR] = 0.249; 95% CI, 0.125–0.495), chemotherapy (HR = 0.473; 95% CI, 0.353–0.633), and grade (HR = 1.374; 95% CI, 1.018–1.854) were independent prognostic factors associated with cancer‐specific survival (CSS), but radiotherapy was not (log‐rank test, p = 0.676).ConclusionsWe constructed a sensitive and discriminative nomogram to identify high‐risk patients with SGC‐NLNM who may harbor dissemination at initial diagnosis. The tumor size and primary site were the largest contributors to DM prediction. Compared with radiotherapy, aggressive surgery, and chemotherapy may be better options for patients with DM.

AbstractBackgroundThe study aimed to clarify the efficacy of the “3‐Day Surprise Question (3DSQ)” in predicting the prognosis for advanced cancer patients with impending death.Patients and MethodsThis study was a part of multicenter prospective observational study which investigated the dying process in advanced cancer patients in Japan. For patients with a Palliative Performance Scale ≤20, the 3DSQ “Would I be surprised if this patient died in the next 3 days?” was answered by their physicians. In addition to the sensitivity and specificity of the 3DSQ, the characteristics of patients who survived longer than expected were examined via multivariate analysis.ResultsAmong the 1896 patients enrolled, 1411 were evaluated. Among 1179 (83.6%) patients who were classified into the “Not surprised” group, 636 patients died within 3 days. Among 232 (16.4%) patients of “Yes surprised” group, 194 patients lived longer than 3 days. The sensitivity, specificity, positive predictive value, and negative predictive value of the 3DSQ were 94.3% (95% confidence interval [CI]: 92.7% to 95.8%), 26.3% (95% CI: 24.8% to 27.6%), 53.9% (95% CI: 53.0% to 54.7%), and 83.6% (95% CI: 78.7% to 87.7%), respectively. Multivariate analysis showed palpable radial artery, absent respiration with mandibular movement, SpO2 ≥ 90%, opioid administration, and no continuous deep sedation as characteristics of patients who lived longer than expected.ConclusionsThe 3‐Day Surprise Question can be a useful screening tool to identify advanced cancer patients with impending death.
Hollow Concave Zinc‐Doped Co3O4 Nanosheets/Carbon Composites as Ultrahigh Capacity Anode Materials for Lithium‐Ion Batteries
Authors: Liang Jin , Kong Jie , Zhang Jian 
Published: December 2020

AbstractComposition‐structure strategy is an effective method to improve the electrochemical performance of lithium‐ion batteries (LIBs). Ideal active materials combined with unique structure can lead to potential candidates for next‐generation LIB anode materials. In this research, we designed a hollow concave Zn‐doped Co3O4 nanosheets/carbon composites as active electrodes for LIBs. The hollow concave structure could shorten the path length of Li+ and electron transfer. The interconnected Co3O4 nanosheets could construct a conductive network and enhance the composites’ conductivity. Moreover, defects produced by Zn doping in the Co3O4 phase improves the electronic structure of Co3O4, endowing superior electrochemical performances for the doped Co3O4‐based composites. As expected, the optimized hollow concave Zn‐doped Co3O4/C composites exhibited high specific capacities with stable cyclability (750 mA h g−1 at 500 mA g−1 after 300 cycles) and excellent rate performances (723.5 mA h g−1 at 3.0 A g−1).
