Anisotropic Growth of Silver Dendrites Regulated by Preferential Adsorption of Nitrate Ions on Crystal Facets
Authors: Huang Haoyang , Dou Xiangyu , Han Yongsheng 
Published: May 2021

AbstractDendritic structures are widely present in nature, from snowflakes to dendritic cells. However, their formation mechanisms are unclear, which causes long unsolved engineering problems, such as lithium dendrites. Here a strategy to control the growth of dendritic structures by the selective adsorption of ions on crystal facets is reported. Silver particles are synthesized by galvanic replacement reaction and the growth anisotropy of crystals is regulated by changing the concentration of nitrate ions in silver nitrate precursor solution. At a low concentration of nitrate ions, messy branching particles are synthesized while symmetric dendrites are generated at a high concentration of nitrate ions. Molecular dynamics simulation suggests that the selective adsorption of abundant nitrate ions on low‐energy facets promotes the prior growth of the high‐energy facets, resulting in the symmetric dendritic structures. When the potassium nitrate is changed to sodium nitrate, similar phenomena are obtained, confirming the role of selective adsorption of additives in regulating the growth anisotropy of crystals.
Hidden fractions: Another look at micronutrient and sodium partitioning in modern cotton cultivars
Authors: Pabuayon Irish Lorraine B. , Lewis Katie L. , Ritchie Glen L. 
Published: May 2021

AbstractCotton (Gossypium hirsutumL.) productivity and nutritional status depend on the uptake and allocation of both macro‐ and micronutrients. Micronutrient deficiencies or toxicities reduce yields and must be corrected to achieve optimal yields. There is evidence that macronutrient uptake and partitioning have changed in modern cultivars, and it is therefore important to know whether a similar change has occurred with micronutrient uptake or partitioning. Total uptake and partitioning of essential micronutrients (boron, B; iron, Fe; manganese, Mn; zinc, Zn; and copper, Cu) and of sodium (Na) in different tissues of modern cultivars (FiberMax 958, FM 958; and Deltapine 1646, DP 1646) and a 1990s cultivar (Paymaster HS26, PM HS26) were determined in 2018 and 2019 at New Deal, TX. These were compared to results obtained in studies conducted 30 yr ago. The total seasonal uptake of Cu and Zn increased, whereas the total seasonal uptake of Fe and Mn decreased in modern cultivars. Newer cultivars FM 958 and DP 1646 partitioned greater percentage of Zn and Cu to the developing bolls compared to PM HS26. Iron and Mn were mostly retained in the leaves throughout the crop's life cycle. Sodium accumulated in nonphotosynthetic tissues likely as a salt‐tolerance mechanism of cotton. However, when Na availability is far more than required for normal plant growth, Na is redistributed and accumulated into transpiring leaves. This study offers additional insights for making effective fertilizer management decisions for newer cultivars and possible problems due to excess trace elements in the soil and irrigation supply.
Sheath fluid impacts the depletion of cellular metabolites in cells afflicted by sorting induced cellular stress (SICS)

Published: May 2021

AbstractFlow cytometrists have long observed a spectrum of cell‐type‐specific changes ranging from minor functional defects to outright cell destruction after purification of cells using conventional droplet cell sorters. We have described this spectrum of cell perturbations as sorter induced cellular stress, or SICS (Lopez and Hulspas, Cytometry, 2020, 97, 105–106). Despite the potential impact of this issue and ubiquitous anecdotes, little has been reported about this phenomenon in the literature, and the underlying mechanism has been elusive. Inspired by others' observations (Llufrio et al., Redox Biology, 2018, 16, 381–387 and Binek et al., Journal of Proteome Research, 2019, 18, 169–181), we set out to examine SICS at the metabolic level and use this information to propose a working model. Using representative suspension (Jurkat) and adherent (NIH/3T3) cell lines we observed broad and consistent metabolic perturbations after sorting using a high‐speed droplet cell sorter. Our results suggest that the SICS metabolic phenotype is a common cell‐type‐independent manifestation and may be the harbinger of a wide‐range of functional defects either directly related to metabolism, or cell stress response pathways. We further demonstrate a proof of concept that a modification to the fluidic environment (complete media used as sheath fluid) in a droplet cell sorter can largely rescue the intracellular markers of SICS, and that this rescue is not due to a contribution of metabolites found in media. Future studies will focus on characterizing the potential electro‐physical mechanisms inherent to the droplet cell sorting process to determine the major contributors to the SICS mechanism.

SummaryThe enormous growth of the Internet of Things (IoT) network provides abundant support to agriculture and development, which states the future scope of IoT‐based agriculture. In a recent scenario, agriculture IoT can be integrated with sensors, communication protocols, and microcontrollers for automated process executions to increase productivity. Moreover, deep learning effectiveness produces appropriate results and solves several real‐time issues related to agriculture‐based advancements. The proposed system presents the design of an IoT network communication system to estimate the soil conditions. Soil quality is an important factor in modernized agriculture, productivity enhancement, and hydrological cycles. By the soil quality analysis, the accurate prediction is very significant for sensible usage of resources. An enhanced deep learning model for IoT network‐based automated soil quality evaluation observes the complex soil features and meteorological factors with those concerns. Here, the real‐time samples are collected from the local area sensor network for analysis. The deep learning model is developed with big data fitting ability for soil quality prediction. The weight factors (W.F.) are derived for measuring the soil quality accurately. The proposed IoT network‐based agriculture structure allows a flexible approach to different types of crops and implementation in agricultural areas. Experimental results obtained in the laboratory and onsite confirmed the performance and reliability of the system. The result evaluations are carried out based on precision, accuracy, and processing time, and results show that the model achieves better results than compared models.

Published: May 2021

SummaryWireless multimedia sensor networks (WMSNs), with its exceptional properties, have found a sturdy and steady spot in automation and surveillance applications. The WMSN had made a massive drift of concentration from the wireless sensor networks with its capability of retrieving multimedia files through multimedia devices. The huge capacity data transfer through the multimedia sensors drain the power capacity of the sensors and is considered to be the vital challenge of the WMSNs. The challenges associated with the WMSNs are the restrictions in resources, connectivity, and security and maintaining a good level of quality of service (QoS). This paper proposes a novel protocol, optimized compressed sensing routing protocol (OCSRP), that performs the routing of multimedia data in a highly efficient manner through which the aforementioned research challenges like resource restrictions and QoS can be addressed. In addition, the security methods were incorporated in routing mechanism, and the results were compared with the existing LEACH algorithm. The quantitative analysis proves that the proposed model possesses high level of QoS with high level of security than the existing security algorithms.
Liposuction‐principles, techniques, outcomes
Authors: Venkataram Jayashree , Mysore Venkataram 
Published: May 2021

AbstractLiposuction is a method of removing unwanted fat through small holes in skin. Tumescent liposuction is a method in which liposuction is performed entirely under local anaesthesia, without any additional intravenous or general anaesthesia. In this method, higher doses of lidocaine are used, often 45 mg/kg, in a highly diluted form in saline along with epinephrine for vasoconstriction. Usually, around 5–6 L of fat is aspirated. This method has been remarkably safe and effective. Powered liposuction, laser liposuction, ultrasound and radiofrequency liposuctions use devices to enhance the efficacy of manual tumescent liposuction. The method has stood the test of time, in both effective and safe outcomes

Published: May 2021

AbstractMale genitalia are usually extremely divergent between closely related species, but relatively constant within one species. Here we examine the effect of temperature on the shape of the ventral branches, a male genital structure involved in reproductive isolation, in the sister species Drosophila santomea and Drosophila yakuba. We designed a semi‐automatic measurement machine learning pipeline that can reliably identify curvatures and landmarks based on manually digitized contours of the ventral branches. With this method, we observed that temperature does not affect ventral branches in D. yakuba but that in D. santomea ventral branches tend to morph into a D. yakuba‐like shape at lower temperature. We found that male genitalia structures involved in reproductive isolation can be relatively variable within one species and can resemble the shape of closely related species’ genitalia through plasticity to temperature. Our results suggest that reproductive isolation mechanisms can be dependent on the environmental context.

AbstractDisturbance can induce some dams to abandon their neonates, whereas others continue parental investment. Understanding the variability of the dam–neonate bond and parental investment of large, mobile species, reclusive during calving, such as moose (Alces alces), can be challenging. Advances in global positioning system (GPS) collar technology and analytical approaches allowed us to better understand the role that dam–neonate proximity plays in maintaining the maternal–neonate bond and maternal investment. In 2013 and 2014, we used movement behavior of 50 free‐ranging GPS‐collared dams and their 74 GPS‐collared neonates during 96 hr postcapture/release of neonates to examine home range (HR) sizes, overlap of their HRs, reunions (≤26 m), and dynamic interactions of their movements. Mean area of 95% kernel density estimator (KDE) HRs of neonates (23.5 ha) not abandoned by their dams was more than 2 times that of abandoned neonates (10.4 ha). Mean HR area of dams continuing to invest in their neonates (104 ha) was smaller than that (897 ha) of abandoning dams. Mean overlap of core (50% KDE) and 95% KDE HRs of dam–neonate pairs when investment continued was 38.7% and 42%, whereas corresponding overlap of HRs associated with abandonment was 0.1% and 2.7%. Mean proportion of pairwise hourly location‐fixes indicative of reunions of dams investing in their neonates was 0.37 and occurred at a mean interval of 2.7 hr. A stronger (p ≤ .05) interaction of mean hourly distances moved (did) between dams investing in their neonates was associated with closer proximity compared with dams abandoning neonates. Our collective data indicate that the spatial proximity of dams investing in their neonates, and their stronger bond, nurtured neonate vitality in a way that reinforced continued investment. In contrast, the abandoning behavior of more distant dams had a diminishing influence on viability of their neonates via nutritional deprivation and limited reciprocal stimulation.

Published: May 2021

AbstractA positive nuclear scintigraphy with hydroxy bisphosphonate bone tracer (99mTc‐HPD) is believed to have high sensitivity (>99%) and specificity (91%) for the diagnosis of transthyretin amyloid cardiomyopathy. We report the case of an 85‐year‐old man with increased thickness of ventricular walls and a positive bone scintigraphy, who was unexpectedly found to have sarcomeric hypertrophic cardiomyopathy at left ventricular endomyocardial biopsy. Congo Red staining, immunohistochemistry, and transmission electronmicroscopy on six left ventricular samples scored negative for amyloidosis but were suggestive for sarcomeric hypertrophic cardiomyopathy. Genetic study did not show TTR and most commonly involved sarcomeric genes mutations. In hypertrophic cardiomyopathy focal cell necrosis related to demand/supply oxygen mismatch, small vessels disease or inflammation could be responsible of a false‐positive bone scintigraphy signal for transthyretin amyloidosis. Because of this, especially in view of a possible specific treatment, endomyocardial biopsy is highly recommended for the correct diagnosis of cardiomyopathies with hypertrophic phenotype.

Published: May 2021

AbstractBimetallic coordination compounds prone to spin‐state‐switching rearrangements via spin‐crossover or valence tautomerism mechanisms are of ongoing interest due to their unique magnetic characteristics. Dinuclear transition metal (Cr, Mn, Fe, Co, Ni, Cu) complexes with redox‐active bridging ligands (tetraoxolenes and their imine derivatives, di‐o‐quinones bearing linker groups) and tetradentate nitrogen‐containing bases (tetraazacyclotetradecane, tris(2‐pyridylmethyl)amine and N,N′‐dialkyl‐2,11‐diaza[3.3]‐(2,6)pyridinophane derivatives) are described from the viewpoint of their electronic structure and magnetic properties. The present review summarizes data on comprehensive investigations of bi‐ and polystable species of such structural architectures, which might be valuable for the chemists and materials scientists involved in the creation of new promising magnetic materials − building blocks for electronic devices of future generations.
Functional Group Variation in tert‐Butyldiphenylsilanes (TBDPS): Syntheses, Reactivities, and Effects on the Intermolecular Interaction Pattern in the Molecular Crystalline State

Published: May 2021

AbstractWe present the preparation of tert‐butyldiphenylsilanes differing in one functional group. The molecular structures of the phenyl (3), methoxy (4), and amino derivatives (5) were elucidated by single‐crystal X‐ray diffraction analysis and their crystal packing investigated by Hirshfeld surface analysis along with 2D fingerprint plots. In the all‐C derivative 3, the high symmetry dependence of the crystal packing enables a multitude of directional C(methyl)−H⋅⋅⋅C(π) interactions between the tert‐butyl and phenyl groups. The methoxy derivative 4 is characterized by considerably short H⋅⋅⋅H contacts possibly resulting from pre‐orienting C(aryl)−H⋅⋅⋅O and C(aryl)−H⋅⋅⋅C(π) hydrogen bonds. In the amino derivative 5, the nitrogen atom is not involved in intermolecular interactions, instead dispersive H⋅⋅⋅H contacts might become more important for the crystal cohesion. These findings once again underline the pronounced lone electron pair density transfer from the nitrogen atom towards the silicon atom.

Published: May 2021

AbstractReactions of thorium tetrahalides ThX4 (X=Cl, Br, I) with liquid ammonia at room temperature lead to the formation of decaammine thorium(IV) halide ammoniates. Their different compositions [Th(NH3)10]X4 ⋅ nNH3 were established by single crystal X‐ray diffraction. While for the chloride the formation of a tetraammoniate is observed, the reaction of the bromide leads to an octaammoniate, whereas the iodide results in approximately a nonaammoniate. Additionally, the formation of the dinuclear Th complex compound [Th2Cl2(NH3)14(μ‐O)]Cl4 ⋅ 3NH3 was observed when moisture was present within NH3. As expected, the Th and the previously reported U compounds [An(NH3)10]Br4 ⋅ 8NH3 (Pbca, An=Th, U), [An(NH3)10]I4 ⋅ 9NH3 (P4/n), and [An2Cl2(NH3)14(μ‐O)]Cl4 ⋅ 3NH3 (P
) are isotypic, respectively. Surprisingly, ThCl4 formed the decaammine complex [Th(NH3)10]Cl4 ⋅ 4NH3 (P121/n1), while UCl4 formed the octaammine chlorido complex [UCl(NH3)8]Cl3 ⋅ 3NH3 (Pnma) in ammonia. Quantum‐chemical gas‐phase calculations were carried out to study the molecular structures and the energetics of the complex cations. In addition, the localized molecular orbitals (LMO) and Intrinsic Bonding Orbitals (IBO) were analyzed. However, the calculations could not explain the preferred formation of the [Th(NH3)10]4+ complex over the hypothetical cation [ThCl(NH3)8]3+.

These BPE‐based electrochromic devices have been used for analytical health monitoring, point‐of‐care (POC) diagnostics, and chemical sensing. In this review, we highlight recent progress made regarding BPE‐based electrochromic devices constructed for these analytical applications. Various, available electrochromic materials are summarized in the first section, after which the different device types (e. g., paper‐based and self‐powered) are discussed. Biological‐ and chemical‐based analytical demonstrations of these devices are then reviewed. Finally, we conclude this review with a perspective on the future developments of BPE‐based electrochromic devices in analytical applications.

Published: May 2021

AbstractThe current research was performed to examine the effects of date seed‐derived biochar (DSDB) for remediation of hazardous metal ions (lead (II) and cadmium (II)) from binary and single systems. The maximum sorption uptakes of 0.484 and 0.798 mmol/g were recorded for lead (II) and cadmium (II) ions, respectively, at an equilibrium pH of 4.5. For both metal ions, DSDB produced quick kinetic uptake rates with most of the removal process (90%) completed within 60 mins. Different types of models were applied to depict lead (II) and cadmium (II) isotherms (Toth, Redlich–Peterson, Freundlich, and Langmuir) and kinetics (pseudo‐first and ‐second order) data. Desorption method was attempted and DSDB was reutilized in five consecutive cycles successfully using 0.01 M HCl as elutant. During binary sorption, decreased uptake of cadmium (II) by DSDB was observed due to the presence of lead (II). In comparison to single solute system, the uptake of cadmium (II) was reduced to 26.5% while only 1.2% reduction for lead (II) was observed. While comparing the two multi‐component isotherm models (Langmuir and Freundlich), the multicomponent Langmuir model performed well in describing the cadmium (II)+lead (II) binary isotherm with high accuracy.

AbstractUltraviolet (UV) radiation has been widely used to monitor insects and conduct surface sterilizations at 365 nm and 254 nm wavelengths, respectively. The global increase in the use of UV light has raised concerns about environmental impacts and effects on non‐target organisms. We, therefore, examined the effects of three UV radiation wavelengths (365 nm, 308 nm and 254 nm) on the survival and antioxidant activities of a tephritid fruit fly, Bactrocera dorsalis. Exposure to UV radiation significantly increased B. dorsalis cohort mortality and the duration of pre‐oviposition. Moreover, the application of UV‐B and UV‐C significantly decreased egg laying. The activities of antioxidant enzymes were irreversibly decreased by UV‐A, UV‐B and UV‐C radiation. Decreases in catalase (CAT), superoxide dismutases (SOD) and glutathione‐S‐transferases (GST) activity were observed at both immediately after exposure and also at 120 h after exposure. However, while peroxidase (POD) activity was decreased immediately after UV‐B and UV‐C radiation, the activity had recovered at 120 h post‐exposure. These results demonstrate UV‐dependent decreases in the activities of antioxidant enzymes are associated with decreased B. dorsalis survival rates. While UV radiation can, therefore, be harmful to non‐target organisms, it is a potential strategy for integrated pest management.
lncRNA PVT1 promotes cetuximab resistance of head and neck squamous cell carcinoma cells by inhibiting miR‐124‐3p

Published: May 2021

AbstractBackgroundCetuximab has been widely used in the clinical treatment of head and neck squamous cell carcinoma (HNSCC). However, whether long non‐coding RNA plasmacytoma variant translocation 1 (lncRNA PVT1) is correlated with cetuximab resistance remains unclear.MethodsWestern blot and qRT‐PCR were performed to quantify the levels of genes and proteins, respectively. Cell functions were measured using Cell Counting Kit‐8 (CCK‐8), Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL), and flow cytometry assays. The methylation level was tested using methylation‐specific PCR (MSP).ResultsPVT1 was upregulated and positively correlated with the poor prognosis of HNSCC. PVT1 overexpression markedly promoted the survival and weakened the cetuximab sensitivity of HNSCC cells, while miR‐124‐3p overexpression showed opposite effects. Mechanistically, the silence of PVT1 indirectly promoted miR‐124‐3p expression by reducing its promoter methylation. Importantly, miR‐124‐3p overexpression impeded the regulatory roles of PVT1 overexpression.ConclusionPVT1 decreased the sensitivity of HNSCC cells to cetuximab by enhancing methylation‐mediated inhibition of miR‐124‐3p, which might provide a new insight for the cetuximab chemoresistance of HNSCC.
