Published: November 2023

Sheath blight of rice caused by Rhizoctonia solani Kuhn is emerging as a very destructive disease causing heavy yield losses. The present study was conducted at Department of Plant pathology, JNKVV, College of Agriculture, Rewa, (M.P.) with eight culture media viz., Potato Dextrose Agar (PDA), Czapek’s Dox Agar (CDA),Richards medium (RMA), Corn Meal Agar (CMA), Oat meal agar (OMA), Rice leaf extract agar (30%),Rice seed extract agar (10%) and Rice seed extract (10%)+ (2%) sucrose were evaluated against R. solani. It can be concluded that Potato dextrose agar (88.0 mm) and Czapek’s dox agar (87.7 mm) medium supported maximum mycelial growth of R. solani isolated from rice. Whereas, least mycelial growth (75.8 mm) was observed in Rice seed extract agar and Richards agar medium. Mycelial growth was excellent fast, abundant and off white on Potato dextrose agar. Whereas it was fast, abundant and on Czapek’s dox agar. Sclerotia of the fungus initiated within 3 - 4 days in different culture media. Maximum number of sclerotia was produced in Oat meal agar (54.0) closely followed by Potato dextrose agar (51.2) and Czapek’s dox agar (44.6). Maximum weight of 10 sclerotia was recorded in potato dextrose agar (1030.6 mg) followed by Czapek’s dox agar (920.3 mg) and Oat meal agar (884.7 mg). Maximum size of sclerotia were formed in Potato dextrose agar followed by Rice seed extract agar and Corn meal agar.

Published: November 2023

Attribute control charts especially p charts have been used widely for statistical process of attribute characteristics. In many applications, however it is neither possible nor practical to obtain sufficient subgroups to estimate accurately the control limits for the conventional p chart. This may occur when the production process is characterized as being a short run. One short run situation is a production run which produces items in a short period of time.
In this article we describe the standardized p chart that the beyond control limit probabilities of proposed chart are closer to 0.135%

Abstract in Bahasa Indonesia :

Peta kendali atribut khususnya peta kendali p banyak digunakan untuk mengendalikan proses yang berkarakteristik atribut. Pada penerapannya proses produksi yang membutuhkan waktu relatif pendek mengakibatkan subgrup yang diperoleh terbatas jumlahnya, sehingga peta kendali p yang terbentuk tak memungkinkan untuk dianalisa.
Dalam artikel ini akan diulas sebuah standarisasi peta kendali p yang diusulkan dengan mempertimbangkan probabilitas data yang keluar dari batas kendali.

ImportanceQuantifying the burden of nosocomial SARS-CoV-2 infections and associated mortality is necessary to assess the need for infection prevention and control measures.ObjectiveTo investigate the occurrence of nosocomial SARS-CoV-2 infections and associated 30-day mortality among patients admitted to hospitals in Region Stockholm, Sweden.Design, Setting, and ParticipantsA retrospective, matched cohort study divided the period from March 1, 2020, until September 15, 2022, into a prevaccination period, early vaccination and pre-Omicron (period 1), and late vaccination and Omicron (period 2). From among 303 898 patients 18 years or older living in Region Stockholm, 538 951 hospital admissions across all hospitals were included. Hospitalized admissions with nosocomial SARS-CoV-2 infections were matched to as many as 5 hospitalized admissions without nosocomial SARS-CoV-2 by age, sex, length of stay, admission time, and hospital unit.ExposureNosocomial SARS-CoV-2 infection defined as the first positive polymerase chain reaction test result at least 8 days after hospital admission or within 2 days after discharge.Main Outcomes and MeasuresPrimary outcome of 30-day mortality was analyzed using time-to-event analyses with a Cox proportional hazards regression model adjusted for age, sex, educational level, and comorbidities.ResultsAmong 2193 patients with SARS-CoV-2 infections or reinfections (1107 women [50.5%]; median age, 80 [IQR, 71-87] years), 2203 nosocomial SARS-CoV-2 infections were identified. The incidence rate of nosocomial SARS-CoV-2 infections was 1.57 (95% CI, 1.51-1.64) per 1000 patient-days. In the matched cohort, 1487 hospital admissions with nosocomial SARS-CoV-2 infections were matched to 5044 hospital admissions without nosocomial SARS-CoV-2 infections. Thirty-day mortality was higher in the prevaccination period (adjusted hazard ratio [AHR], 2.97 [95% CI, 2.50-3.53]) compared with period 1 (AHR, 2.08 [95% CI, 1.50-2.88]) or period 2 (AHR, 1.22 [95% CI, 0.92-1.60]). Among patients with nosocomial SARS-CoV-2 infections, 30-day AHR comparing those with 2 or more doses of SARS-CoV-2 vaccination and those with less than 2 doses was 0.64 (95% CI, 0.46-0.88).Conclusions and RelevanceIn this matched cohort study, nosocomial SARS-CoV-2 infections were associated with higher 30-day mortality during the early phases of the pandemic and lower mortality during the Omicron variant wave and after the introduction of vaccinations. Mitigation of excess mortality risk from nosocomial transmission should be a strong focus when population immunity is low through implementation of adequate infection prevention and control measures.

ImportanceBlack individuals in the US experience stroke and stroke-related mortality at younger ages and more frequently than other racial groups. Studies examining the prospective association of interpersonal racism with stroke are lacking.ObjectiveTo examine the association of perceived interpersonal racism with incident stroke among US Black women.Design, Setting, and ParticipantsThe Black Women’s Health Study, a prospective cohort study of 59 000 Black women from across the US, assessed the longitudinal association between perceived interpersonal racism and stroke incidence. Stroke-free participants were followed up from 1997 until onset of stroke, death, loss to follow-up, or the end of the study period (December 31, 2019). Cox models were used to estimate hazard ratios (HRs) and 95% CIs, adjusting for major confounders, including education, neighborhood socioeconomic environment, and cardiometabolic factors. Data analysis was performed from March 2021 until December 2022.ExposureOn a questionnaire completed in 1997, participants reported experiences of racism in everyday life and when dealing with situations that involved employment, housing, and interactions with police.Main Outcomes and MeasuresStrokes were identified through self-report on biennial questionnaires, medical records adjudication, and linkage with the National Death Index.ResultsIn 1997, 48 375 Black women (mean [SD] age, 41 [10] years) provided information on perceived interpersonal racism and were free of cardiovascular disease and cancer. During the 22 years of follow-up, 1664 incident stroke cases were identified; among them, 550 were definite cases confirmed by neurologist review and/or National Death Index linkage. Multivariable HRs for reported experiences of racism in all 3 domains of employment, housing, and interactions with police vs no such experiences were 1.38 (95% CI, 1.14-1.67), a 38% increase, for all incident cases and 1.37 (95% CI, 1.00-1.88) for definite cases. For comparisons of women in the highest quartile of everyday interpersonal racism score vs women in the lowest quartile, multivariable HRs were 1.14 (95% CI, 0.97-1.35) for analyses that included all incident stroke and 1.09 (95% CI, 0.83-1.45) for analyses that included definite cases only.Conclusions and RelevanceIn this study, Black women who reported experiences of interpersonal racism in situations involving employment, housing, and interactions with police appeared to have an increased risk of stroke, even after accounting for demographic and vascular risk factors, suggesting that the high burden of racism experienced by Black US women may contribute to racial disparities in stroke incidence.

Published: November 2023

AbstractPolymer membranes with high permeability, high salt rejection, and mechanical integrity are desirable in water treatment and purification. However, it remains a daunting challenge to achieve ultrathin yet robust polymer membranes harvesting all the above features for nanofiltration. Here, a new approach of nano‐confined supramolecular assembly to fabricate ultrathin crystalline polymer membranes with a modulus of 1 GPa and a thickness of 6.5 nm is reported. The microdroplet carrying amphiphilic tetra‐oligomers can quickly spread at the air–‐water interface, where the hydrophilic motifs such as carbonyl and hydroxyl groups can reconfigurably anchor down to water molecules via abundant hydrogen bonding interactions, significantly promoting the alignment and orientation of hydrophobic alkyl chains within the nano‐confined space. The resultant nano‐films exhibit mechanical robustness as well as excellent ion sieving with improved NaCl rejection of 81.3% and unprecedented Na2SO4 rejection of 99.9% without compromising water permeation, outperforming the reported and commercial state‐of‐the‐art polymer membranes. This work enables the rapid production of over 100 cm2 ultrathin crystalline polymer membranes with great nanofiltration potential and highlights the critical role of supramolecular assembly in the chemical and structural configurations in a nano‐confined space.

Published: November 2023

AbstractSuccessful regeneration of the peripheral nerve relies on the collaborative efforts of neural cells and immune cells. Conductive hydrogels have yielded promising results in supporting axonal growth; however, their inability to regulate the immune response and their poor biological integration with tissues hinder the repair of injured peripheral nerves. Herein, an adhesive conductive immunomodulatory nerve hydrogel bandage is developed for nerve regeneration. The nerve bandage hydrogel is prepared from the bioactive material extracellular matrix (ECM), oxidized polysaccharides, and poly(3,4‐ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) by self‐assembly and dynamic Schiff base cross‐linking. The drug indole‐3‐propionic acid (IPA) is loaded into nerve bandages and contributes to the rapid chemotaxis of neutrophils in the dorsal root ganglia and modulation of the immune system. In addition, the conductive hydrogel bandage exhibits close conformal contact with the injured nerve, forming a stable and tightly coupled electrical bridge with the electroresponsive neural tissue. In summary, the nerve bandage effectively promote nerve regeneration and enable both anatomical and functional recovery of neural tissue while preventing muscle atrophy. This work provides a new strategy for peripheral nerve regeneration and may have critical clinical applications in the future.

Published: November 2023

AbstractCells rely on secreted signaling molecules to coordinate essential biological functions including development, metabolism, and immunity. Unfortunately, such signaling processes remain difficult to measure with sufficient chemical specificity and temporal resolution. To address this need, an aptamer‐conjugated hydrogel matrix that enables continuous fluorescent measurement of specific secreted analytes – in two dimensions, in real‐time is developed. As a proof of concept, real‐time imaging of inter‐cellular cyclic adenosine 3',5'‐monophosphate (cAMP) signals in Dictyostelium discoideum amoeba cells is performed. A set of aptamer switches that generate a rapid and reversible change in fluorescence in response to cAMP signals is engineered. By combining multiple switches with different dynamic ranges, measure cAMP concentrations spanning three orders of magnitude in a single experiment can be measured. These sensors are embedded within a biocompatible hydrogel on which cells are cultured and their cAMP secretions can be imaged using fluorescent microscopy. Using this aptamer‐hydrogel material system, the first direct measurements of oscillatory cAMP signaling that correlate closely with previous indirect measurements are achieved. Using different aptamer switches, this approach can be generalized for measuring other secreted molecules to directly visualize diverse extracellular signaling processes and the biological effects that they trigger in recipient cells.
Designing Chemically Replaced Interfacial Layer via Unveiling the Influence of Zn Crystal Facets for Practical Zn‐Metal Anodes

Published: November 2023

AbstractZn metal anodes (ZMAs) undergo irregular deposition and unfavorable side reactions, which hinders the practical application of aqueous rechargeable Zn metal batteries (ARZMBs). Chemical replacement reaction (CRR) strategies can achieve stable ZMAs, but the effect of the crystal facets of metallic Zn as reductants remains poorly understood. In this study, based on the observation that preferentially exposed Zn crystal facets affect the surface characteristics of chemically replaced layers in Sn‐based CRR, a multifunctional Sn‐based interfacial layer (ZnTCF@Sn) is designed on the Zn with textured crystal facets using a novel two‐step CRR process. ZnTCF@Sn simultaneously provides abundant zincophilic sites and high surface energy and homogenizes the distribution of current/Zn2+ flux, resulting in fast electrochemical kinetics and dendrite‐free deposition. Furthermore, the uniform Sn coverage on the ZnTCF@Sn surface inhibits side reactions and enhances reversibility during Zn deposition/dissolution. Thus, the ZnTCF@Sn achieves exceptional cyclability over 1200 h even under harsh operating conditions with a cumulative capacity of 24 Ah cm−2. This study contributes to the development of practical ARZMBs by providing new insights into the effect of the Zn crystal facets on the surface modification of ZMAs through various CRRs.

AbstractHuman decellularized bone fragments are commonly used in clinics to perform allograft surgeries. To reduce the immunological response in the recipient and ensure their safety, these fragments underwent decellularization, a procedure that greatly reduces their osteogenicity (the ability to induce differentiation into osteoblast). In this work, by the introduction of an ultrasonication step to fragment the human bone, the size distribution of the resulting demineralize bone particles can be controlled, tuning their osteogenic potential. The sonication protocol is optimized by a response surface method, using 12 different sonication protocols, allowing to model the relationship between the sonication parameters and the outcoming particles properties in terms of dimensions, physical/chemical properties, and biological activity. The size distribution is extrapolated by a deep learning image segmentation while the structure is characterized by infrared and thermal analysis. The particles are combined with methacrylated silk gel to test in vitro their biological response on adipose‐derived stromal cells. The ultrasonication fragmented the bone particles, revealing their internal organic matrix as proved by secondary electron microscopy and confocal microscopy. An inverse linear correlation is found between the particles’ sizes and their osteogenic activity, thus proving the efficacy of the proposed ultrasonication treatment in tuning the biological response.
Packaged Elastomeric Optical Fiber Sensors for Healthcare Monitoring and Human‐Machine Interaction
Authors: Zhang Zhenhua , Zhang Lei 
Published: November 2023

Elastomeric polymer optical fiber (EPOF) enabled flexible optical sensors have been attracting intensive research interest due to their excellent stretchability, sensing performance, and anti‐electromagnetic interference. However, a soft EPOF without effective protection tends to be damaged, which may undermine its long‐term stability, and thus, limit its practical applications. In this work, a strategy for packaging a section of EPOF is proposed, a light‐emitting diode (LED), and a photodiode (PD) into a stretchable and flexible silicone patch for both healthcare and human‐machine interaction applications. The silicone package not only protects the EPOF from environmental disturbance, providing a compact sensing approach for conformal attachment on flexible or curved surfaces but also offers an effective manner to adjust the sensitivity and working range of the EPOF sensors. Typically, an EPOF sensor is sensitive to pressure, strain, or bending. As a proof‐of‐concept demonstration, a laryngoscope equipped with a packaged EPOF sensor that can bear a pressure of 60 MPa is developed. It can effectively avoid teeth damage by real‐time monitoring the contact force during the operation. Furthermore, a data glove with five packaged EPOF sensors for hand gesture recognition and remote control of a micro‐vehicle is fabricated.

Published: November 2023

AbstractDesigning efficient and bifunctional electrocatalysts for water splitting conforms to the concept of energy conservation and emission reduction but remains challenging now. Herein, the fabrication of a heterostructure by anchoring cobalt‐polyoxometalates (Co‐POM) on NiFe layered double hydroxide (NiFe‐LDH) nanoplates in situ on nickel foam (NF) is first reported (Co‐POM@LDH/NF). The surface area, electron transfer ability, and stability of the heterostructure are increased due to the synergistic effect between Co‐POM and NiFe‐LDH. Particularly, Co‐POM@LDH/NF can deliver a current density of 100 mA cm−2 with an overpotential of only 220 mV for hydrogen evolution reaction (HER) and 226 mV for oxygen evolution reaction (OER) in 1.0 m KOH electrolytes. Impressively, the outstanding stability of Co‐POMs in heterostructures is verified by the experimental observations after electrolysis, indicating the successful construction of stable POMs‐based heterogeneous electrocatalysts. More attractively, the electrolyzer composed by Co‐POM@LDH/NF as anode and cathode shows a much lower operating voltage of 1.51 V at the current density of 10 mA cm−2 for overall water splitting. This study provides a feasible and extensible idea for the design of the POM‐based heterostructures.
