Purification, structural characterization and immunological activity of Sibiraea laexigata (L.) Maxim polysaccharide

Sibiraea laexigata (L.) Maxim (SLM) has been used as an herbal tea for treating stomach discomfort and indigestion for a long time in china. Polysaccharides have been identified as one of the major bioactive compounds in the SLM. In the present paper, ultrasonic-assisted enzymatic extraction (UAEE) method was employed in polysaccharides extraction derived from SLM using polyethylene glycol (PEG) as extraction solvent, two SLM polysaccharides (SLMPs) fractions (SLMPs-1-1 and SLMPs-2-1) were purified by DEAE Cellulose-52 and Sephadex G-100 chromatography in sequence. Then, the preliminarily structure of the two factions were characterized by chemical composition analysis, molecular weight measurement, UVS, HPLC-PMP, FT-IR, nuclear magnetic resonance (NMR) spectra analysis and SEM. The results showed that SLMPs-1-1 and SLMPs-2-1 with different molecular weights of 1.03 and 1.02 kDa, mainly composed of glucose (46.76 and 46.79%), respectively. The results of structural characterization from FT-IR, 1H NMR, and SEM revealed that SLMPs-1-1 and SLMPs-2-1 contained the typical pyranoid polysaccharide with α-glycosidic bond and β-glycosidic bond. Furthermore, it was found that SLMPs-1-1 could increase the levels of tumor necrosis factor-α (TNF-α) and interleukin-2 (IL-2), and alleviated the immune organs tissue damage of cyclophosphamide (Cy)-treated mice. RT-qPCR and Western-Blot analysis showed that SLMPs-1-1 could significantly up-regulated the levels of NF-κB, TLR4, which revealed that SLMPs-1-1 could participate in immunosuppressive protection of Cy-treated mice. These findings suggested that the potential of SLMPs-1-1 as an alternative immunostimulator could be used in food and pharmaceutical industries.
Comparison of Polyethylene and Polyethylene-coated Bio-degradeable Paper Mulches on Strawberry1

Bio-degradeable paper mulches with a polyethylene (PE) coating on both sides or with a single PE coating applied against the soil surface satisfactorily endured Florida's 7 month growing season and gave similar fruit yields and fertilizer leaching results as compared to black PE mulch. Paper mulch was harder to transplant through since it is less flexible than PE mulch, but it does not have to be removed from the Geld at season's end.
Topographic Reconstruction of the “Tianwen-1” Landing Area on the Mars Using High Resolution Imaging Camera Images

High-resolution optical cameras have always been important scientific payloads in Mars exploration missions, and the Mars topographic data produced by their detection data can provide support for scientific research on Mars geomorphology and geological structure evolution. As of December 2021, there are still relatively few high-resolution image data at the submeter level on the Martian surface, with about 2.6% global coverage and even more limited stereo coverage (just about 0.4%). At the same time, there are still some difficulties in data acquisition and terrain reconstruction processing methods for high-resolution Mars images that need to be solved. This article described how we designed the in-orbit stereo imaging strategy based on the characteristics of the high-resolution imaging camera (HiRIC) of China’s first Mars exploration mission (Tianwen-1), studied the technical solutions for HiRIC stereo image photogrammetry processing, and produced a topographic dataset for the “Tianwen-1” landing area, including a digital orthophoto map (DOM) with a ground sample distance (GSD) of 0.7 and 3.5 m and a digital elevation model (DEM) with a GSD of 3.5 m. Precision analysis results show that these topographic data have good consistency in planar position and elevation compared with the existing Mars terrain data and have advantages in spatial resolution and terrain detail expression, which will be widely used in the geological background study of the “Tianwen-1” landing area, as well as landing site positioning, Martian surface remote operation planning, and other Mars scientific research and engineering tasks.
Semiclassical approximations to 3j- and 6j-coefficients for quantum­ mechanical coupling of angular momenta An inverse problem in statistical mechanics Direct determination of the Iwasawa decomposition for noncompact

The coupling of angular momenta is studied using quantum mechanics in the limit of large quantum numbers (semiclassical limit). Uniformly valid semiclassical expressions are derived for the 3j (Wigner) coefficients coupling two angular momenta, and for the 6j (Racah) coefficients coupling three angular momenta. In three limiting cases our new expressions reduce to those conjectured by Ponzano and Regge. The derivation involves solving the recursion relations satisfied by these coefficients, by a discrete analog of the WKB method. Terms of the order of the inverse square of the quantum numbers are neglected in the derivation, so that the results should be increasingly accurate for larger angular momenta. Numerical results confirm this asymptotic convergence. Moreover, the results are of a useful accuracy even at small quantum numbers.
Comment on "Quantification of Macroscopic Quantum Superpositions within Phase Space"

The phase space measure proposed by Lee and Jeong [PRL 106, 220401 (2011)] is shown to be closely related to a well-studied measure in the literature. For pure states, the newly proposed measure is equivalent to an old measure; for mixed states, some discussions are given.
Higher Na+-Ca2+ Exchanger Function and Triggered Activity Contribute to Male Predisposition to Atrial Fibrillation

Male sex is one of the most important risk factors of atrial fibrillation (AF), with the incidence in men being almost double that in women. However, the reasons for this sex difference are unknown. Accordingly, in this study, we sought to determine whether there are sex differences in intracellular Ca2+ homeostasis in mouse atrial myocytes that might help explain male predisposition to AF. AF susceptibility was assessed in male (M) and female (F) mice (4–5 months old) using programmed electrical stimulation (EPS) protocols. Males were 50% more likely to develop AF. The Ca2+ transient amplitude was 28% higher in male atrial myocytes. Spontaneous systolic and diastolic Ca2+ releases, which are known sources of triggered activity, were significantly more frequent in males than females. The time to 90% decay of Ca2+ transient was faster in males. Males had 54% higher Na+-Ca2+ exchanger (NCX1) current density, and its expression was also more abundant. L-type Ca2+ current (ICaL) was recorded with and without BAPTA, a Ca2+ chelator. ICaL density was lower in males only in the absence of BAPTA, suggesting stronger Ca2+-dependent inactivation in males. CaV1.2 expression was similar between sexes. This study reports major sex differences in Ca2+ homeostasis in mouse atria, with larger Ca2+ transients and enhanced NCX1 function and expression in males resulting in more spontaneous Ca2+ releases. These sex differences may contribute to male susceptibility to AF by promoting triggered activity.
Perception of Cigarette Graphic Health Warnings and Its Impact on Smoking Behavior: A Cross-Sectional Study among Current Smokers of Western Part of Nepal

Globally, tobacco use (smoked, secondhand, and chewing) accounted for 8.71 million deaths, which is 15.4% of all deaths in 2019. Tobacco was ranked first among males and sixth among female in terms of level 2 risk factor for attributable deaths globally. The objective of this study was to identify the perception of cigarette graphic health warnings and their impact on smoking behavior in Nepal. A cross-sectional study using purposive sampling technique was done. Out of 169 respondents, 79.9% were male, 49.1% were illiterate, and 37.9% were above 60 years of age. Eighty-four percent had initiated smoking before the age of 20, and 39.6% had smoked cigarettes for more than 40 years. All the respondents had noticed the graphic health warning on cigarette packages. The majority (80.5%) of the respondents reported that the warning informs about specific health consequences of smoking, and the percentage of respondents believing that warning motivates smokers to quit smoking, encourages smokers to reduce the number of cigarettes smoked per day, and deters potential smokers from starting to smoke was 40.2%, 33.1%, and 30.8%, respectively. More than half of the respondents (50.9%) attempted to quit smoking because of the warning. The implementation of graphic health warnings had favorable perception from majority of smokers and positive impact on smoking behavior of the respondents. Further large-scale research on impact on smoking behavior through repeated cross-sectional studies can be future research priority.
Design of a compact multifunctional power divider loaded with short‐ended stub

The article presents a compact multifunctional power divider loaded with short‐ended stub for RF front end system at 2.5 GHz application. The proposed structure consists of PIN diodes and short‐ended stub at the output transmission line. Wilkinson power divider and SPDT switch at 2.5 GHz can be achieved by changing the bias voltage of the integrated PIN diodes. As the proposed design transitions from a power divider to an SPDT switch, a short stub is introduced at the output ports to prevent mismatches from occurring. The proposed SPDT switch design has been mathematically analyzed and presented in detail. Two frequency component functions are combined in a small package with three RF connectors. This proposed design is constructed and characterized for experimental‐demonstration purposes. The method proposed in this article is simpler compared to the previous work and easy to fabricate. This technique will reduce the overall size and manufacturing cost. It also can be applied to design the multifunctional power divider at any desired specifications and operating frequencies that compatible with RF/microwave applications, such as smart antennas and phase‐array antennas.
Pulmonary Artery Banding for Dilated Cardiomyopathy in Children: Returning to the Bench from Bedside

Current treatment paradigms for end-stage dilated cardiomyopathy (DCM) in children include heart transplantation and mechanical support devices. However, waitlist mortality, shortage of smaller donors, time-limited durability of grafts, and thrombo-hemorrhagic events affect long-term outcomes. Moreover, both these options are noncurative and cannot preserve the native heart function. Pulmonary artery banding (PAB) has been reinvented as a possible “regenerative surgery” to retrain the decompensated left ventricle in children with DCM. The rationale is to promote positive ventricular–ventricular interactions that result in recovery of left ventricular function in one out of two children, allowing transplantation delisting. Although promising, global experience with this technique is still limited, and several surgical centers are reluctant to adopt PAB since its exact biological bases remain unknown. In the present review, we summarize the clinical, functional, and molecular known and supposed working mechanisms of PAB in children with DCM. From its proven efficacy in the clinical setting, we described the macroscopic geometrical and functional changes in biventricular performance promoted by PAB. We finally speculated on the possible underlying molecular pathways recruited by PAB. An evidence-based explanation of the working mechanisms of PAB is still awaited to support wider adoption of this surgical option for pediatric heart failure.
Indigenous, Yellow-Feathered Chickens Body Measurements, Carcass Traits, and Meat Quality Depending on Marketable Age

Simple Summary With an increasing trend in chilled chicken sale and consumers’ preference for indigenous chickens in China, commercial, yellow-feathered chickens are confronted with some carcass trait challenges after slaughter, and age is considered to be an important factor in the quality of chickens. Therefore, we compared two marketable ages (90 days and 100 days) on body measurements, slaughter performance, carcass traits, and meat quality in indigenous, yellow-feathered chickens. This current work shows that extending the marketing age to 100 days improves slaughter performance and meat quality in terms of protein and intramuscular fat contents, but shortening the marketing age to 90 days enhances the quality of carcass characteristics such as follicle density and skin color, especially the spotted skin proportions, and improves meat quality traits such as pH and shear force. The results indicated that chickens on day 90 have a better carcass appearance, which is one of the most intuitive references and will alleviate carcass trait problems in the chilled sale of chickens. We concluded that adjusting the marketable age can be an effective method to drive chilled sales and helps producers to satisfy consumers from different regions in indigenous, yellow-feathered chickens. Abstract Given an increasing trend in slaughter and chilling for the sale of chickens in China, it is important to determine the marketable age of chickens for chilled sales. This study determined the effects of two marketable ages on the body measurements, carcass traits, and meat quality of yellow-feathered chickens. A total of 360 healthy one-day-old male Xueshan chickens were raised in six pens (straw-covered floor, numbered 1 to 6) and treated in the same manner (free access to food and water) until day 100. Sixty chickens from pens numbered 1 to 3 and 4 to 6 were selected to determine the body measurements, carcass traits, and meat quality at two slaughter ages (90 and 100 days), respectively. One hundred-day-old chickens had a higher body slope, cockscomb, keel, shank lengths, and higher live and dressed weights (p < 0.05). The abdomen skin follicle density, a*(redness) and b*(yellowness) values were higher in 100-day-old chickens (p < 0.05), whereas the 90-day-old chickens were characterized by better spotted skin. For the breast muscle, pH, shear force, a*, moisture, and protein and intramuscular fat contents were lower; moreover, L*(lightness) and b* were higher in 90-day-old chickens. In leg muscles, the pH, shear force, L*, b* and collagen content were lower; furthermore, the a* and moisture contents were higher in 90-day-old chickens (p < 0.05). These findings indicate that two marketable ages both have pros and cons, but 90 days chickens perform better on carcass appearance, and producers can adjust the marketable age to meet needs of different consumers. This study provides a unique idea and theoretical reference for breeding and marketing yellow-feathered chickens.
Liver Kinase B1 Functions as a Regulator for Neural Development and a Therapeutic Target for Neural Repair

The liver kinase B1 (LKB1), also known as serine/threonine kinase 11 (STK11) and Par-4 in C. elegans, has been identified as a master kinase of AMPKs and AMPK-related kinases. LKB1 plays a crucial role in cell growth, metabolism, polarity, and tumor suppression. By interacting with the downstream signals of SAD, NUAK, MARK, and other kinases, LKB1 is critical to regulating neuronal polarization and axon branching during development. It also regulates Schwann cell function and the myelination of peripheral axons. Regulating LKB1 activity has become an attractive strategy for repairing an injured nervous system. LKB1 upregulation enhances the regenerative capacity of adult CNS neurons and the recovery of locomotor function in adult rodents with CNS axon injury. Here, we update the major cellular and molecular mechanisms of LKB1 in regulating neuronal polarization and neural development, and the implications thereof for promoting neural repair, axon regeneration, and functional recovery in adult mammals.
Quantum Thouless-Anderson-Palmer equations for glassy systems

We derive Thouless-Anderson-Palmer (TAP) equations for quantum disordered systems. We apply them to the study of the paramagnetic and glassy phases in the quantum version of the spherical p spin-glass model. We generalize several useful quantities (complexity, threshold level, etc.) and various ideas (configurational entropy crisis, etc), that have been developed within the classical TAP approach, to quantum systems. The analysis of the quantum TAP equations allows us to show that the phase diagram (temperature-quantum parameter) of the p spin-glass model should be generic. In particular, we argue that a crossover from a second order thermodynamic transition close to the classical critical point to a first order thermodynamic transition close to the quantum critical point is to be expected in a large class of systems.

Molecular Characterisation and Antimicrobial Resistance Patterns of Shiga Toxin Producing Escherichia coli Isolated from Farm Water Samples

Shiga toxin-producing Escherichia coli (STEC) strains are considered the most common food-borne zoonotic pathogen and are highly pathogenic to humans in low infectious doses, causing food-borne diseases through consumption of contaminated water or food. Resistance against antibiotics by STEC is a big concern nowadays. Two hundred farm water samples (Cattle-40, Buffaloes-40, Sheep-30, Goat-20, Pig-20 and poultry-50) were collected aseptically from different livestock farms in and around Proddatur, Andhra Pradesh, India and Processed for E. coli isolation, identification with culture method and molecular characterization by PCR. E. coli was characterized as STEC with two genes i.e. stx1 and stx2. All the STEC isolates were subjected to an antibiotic sensitivity test by disc diffusion method against ten antibiotics. Results showed that out of 200 farm water samples, 196 were positive for E. coli with an overall prevalence of 98% (196/200) and 62.2% (122/196) for STEC by PCR. Antimicrobial susceptibility test by disc diffusion method against ten antibiotics revealed the higher resistance to Cepahlothin (100%) followed by Tetracyclin (98.4%), Ampicillin (96.7%), Streptomycin (95%), Sulphonamides (91.8%), Trimethoprim (84.4%), Kanamycin (34.4%), Chloromphenicol (17.2%), Colistin (9.0%) and least resistance to Gentamycin (4.9%).
Swiss human geographies lecture 2019 tourism troubles: feminist political ecologies of land and body in Panama

Abstract. On the Panamanian Caribbean coast and the Bocas del Toro Archipelago, foreign direct investment via residential tourism development drives land displacement. As land insecurities grow, particularly for local Indigenous and Afro-Panamanian peoples, ongoing dispossession is not simply about land, but rather simultaneously about land, people and their bodies. In Bocas, foreign land enclosures are infused with imaginaries, which take for granted Black female servitude and Black landlessness. Such imaginaries seemingly lock economically “poor” Afro-Panamanian women into particular kinds of work. To illustrate, I entangle feminist political ecological assertions that struggles over nature are embodied struggles, with intersectional and relational understandings of land and body. To do so, I draw insights from postcolonial, decolonial and Black feminist critiques of coloniality and settler colonialism. Building from this literature, I seek to show how a logic of elimination operates within the legal geographies of residential tourism development. In doing so, I highlight the historical and contemporary ways in which Afro-Panamanian women are naturalized as criadas (maids), a process that accompanies land enclosure. Blending ethnographic and historical data collection, I seek to illuminate how Afro-Panamanian women's livelihood struggles reflect both their acquiescence to residential tourism development, and their resilience in the face of Bocas' anti-black patriarchal coloniality. Thus, I argue that Afro-Panamanian women's desires for inclusion and belonging in Bocas' tourism enclave – a project that seeks to eliminate Indigenous and Black relations to coastal lands and foster their embodied subjection to foreign nationals – simultaneously reflects their struggles for the right to remain on the coast.
PBidm: Privacy-Preserving Blockchain-Based Identity Management System for Industrial Internet of Things

Industrial Internet of Things (IIoT) is revolutionizing plenty of industrial applications by utilizing large-scale smart devices in manufacturing and industrial processes. However, IIoT is facing the disclosure of identity privacy. The identity information is precious and critical, thereby inspiring a line of follow-up privacy-preserving studies, i.e., anonymous credential protocols, or privacy-preserving identity management schemes. However, they are either too anonymous to be used in the IIoT environment, or the system is highly centralized, which implies the risk of a single point of failure. In this article, we propose PBidm, a privacy-preserving blockchain-based identity management scheme for IIoT. Specifically, by leveraging blockchain and diversified cryptographic tools, PBidm can fully support the desirable properties, i.e., unforgeability, blindness, unlikability, traceability, revocability, and public verifiability. Then, we provide security analysis to ensure reasonable security assurance. Finally, we present a performance evaluation of the proposed scheme to demonstrate the practicability in IIoT applications.
