Abstract
In addition to being an important household appliance, the microwave is an effective method for food processing and chemical synthesis. Recently, the effect of MW on water hydrogen bonds dynamic was quantified via the in-situ refractive index measurement. This study applied the technique to aqueous solutions with three solutes: ethanol, NaCl and glucose. It was found that ethanol enhanced the MW-induced effect on water structure. In contrast, NaCl reduced the magnitude of MW-induced impact. The influence of glucose varied critically with concentration. At a high concentration, glucose increased RI during the microwave. The findings can clarify and predict the efficiency of MW processes, which are widely used for chemical systhesis, nutrient extraction and food processing.

Abstract

Foodborne diseases are a serious public health problem worldwide, frequently caused by bacterial pathogens, many of these microorganisms are capable of protecting themselves from unfavorable environmental conditions by forming a biofilm, which allows them to colonize successfully inert surfaces and living substrates, such as edible fruits. The objective of this study was to evaluate the formation of biofilms by Escherichia coli of different origins, using the microtiter technique, which allows measuring the Optical Densities (OD) produced by the adhesion of bacterial communities to the surfaces, we evaluated a total of 12 E. coli strains, using two different culture media (minimum essential medium with glucose and Bertanni broth) and 24, 48 and 72 hours of incubation. The results showed that the strains differed in their biofilm production levels, with no difference between the two-culture media, reaching its maximum production level at 72 hours. Once the biofilm production results were obtained, the E. coli-producing strains, serotype O157:H7 and 93300 157:H7, were subjected in the laboratory to a bacterial adhesion test on the epidermis of tomato fruits (Solanum lycopersicumL. ) in order to obtain OD, an acetic-curing silicone-based well was designed, which allowed the microtiter technique to be used accurately; when favorable results were obtained, the study was set up under greenhouse conditions, simulating the natural form of these bacteria to reach the fruits still cultivated, the results showed that both strains form biofilms in the tomato fruits, both in green and ripe fruits, greenhouse conditions provide microenvironmental advantages to the bacteria capable of protecting them from external conditions, including the cleaning and disinfection, which could increase its incidence and morbidity.

Abstract
Since the onset of the pandemic, neurological manifestations of COVID-19 are increasingly being reported in the scientific literature. However, since these manifestations are not the primary symptoms, SARS-CoV-2 is not being considered the etiological agent in most cases. The primary objective of this study was to screen for anti-SARS-CoV-2 antibodies in cerebrospinal fluid (CSF) of patients with neurological manifestations of undiscerned etiology and correlate the antibody levels with the clinical characteristics, derangement in blood & CSF biochemical parameters, comorbidities, radiological findings and prognosis. CSF samples of clinically suspected encephalitis cases of unknown etiology, during the pandemic period (January 2021 to April 2022) were included in the study. Patients were categorised into two groups based on the presence or absence of anti-SARS-CoV-2 antibodies (IgG and IgM) in the CSF. Statistical analysis was done using IBM SPSS Statistics (Version 20.0) software. Out of 112 samples tested, 89 samples had IgG antibodies and three samples had both IgM and IgG antibodies against SARS-CoV-2 virus. Viral nucleic acid could not be detected in any of the tested CSF samples. Altered sensorium and fever were found to be the most significant clinical symptoms associated with the presence of anti-SARS-CoV-2 antibodies in the CSF. An increase in CSF biochemical parameters like glucose, protein, white blood cells along with blood biochemical parameters like serum albumin, alanine transaminase and C - reactive protein was seen in patients who had anti-SARS-CoV-2 antibodies in the CSF. Statistically, no significant correlation was found between the presence of anti-SARS-CoV-2 IgG antibodies and the clinical and biochemical parameters in both groups of patients.

Abstract
In order to explore the spatio-temporal evolution law of surface heat flux during the urbanization process in new mountainous development city, the spatio-temporal evolution law of heat balance process of different land use types and heat flux process before, during and after urbanization in Yuelai New City were analyzed by satellite remote sensing image data and SEBAL model, the effect of land use/vegetation cover on surface heat flux was also discussed. The results include (1) the net radiation flux and difference of various land use types in Yuelai New City reached the maximum in July and the minimum in January, vegetation coverage was one of the factors affected sensible heat flux of different land use types. The order of latent heat flux was woodland > farmland > bare land > residential land, and the order of soil heat flux was bare land > residential land > woodland > farmland. (2)The urbanization process increased the area of low net radiation value in Yuelai New City, and sensible heat flux showed an increasing trend and accounted for the largest proportion in the energy output. The low value area of latent heat flux gradually expanded to the north and south. Soil heat flux and sensible heat flux were higher in the area with low latent heat flux. The distribution rules of soil heat flux and sensible heat were basically consistent, and both showed an increasing trend. (3)The correlation between soil heat flux and land use area was the best among the energy output factors. Fractional vegetation cover(FVC) had a greater impact on heat fluxes than land use area. Residential combined land was most closely related to FVC, and latent heat flux was most affected by FVC.

Abstract
Leptospirosis is a zoonotic disease caused by pathogenic serovars of Leptospira spp. Wild rodents (Rattus norvegicus) are considered principal reservoir for Leptospira spp. The aim of this study was isolation and identification of Leptospira spp circulating amongst wild rodent’s population in Zaria and its environs. Based on convenience sampling, three hundred and five (305) wild rodents (Rattus Norvegicus) from different locations in Zaria and its environs were trapped using 30 steel local wire traps (18+12+28 cm). The traps were baited with dry fish, groundnut, peanut and were placed in selected sampling points of abattoir, poultry farms, settled cattle farms, grain markets, feed stores and bushes. A total of 305 kidney tissue samples were collected aseptically into a sterile-labeled-sample bottles from the trapped wild rodents following euthanasia. Small pieces (2 cm) of the kidney tissues were cut off and placed into a sterile syringe without needle, and further squeezed into Ellinghausen-McCullough-Johnson-Harris (EMJH) media. The EMJH media with the inoculated kidney tissues were kept at 30oC in an incubator for 8 weeks before confirmation of positive isolates using dark field microscopy. Genomic DNA was extracted directly from 24 kidney tissue samples for molecular detection of pathogenic Leptospira spp. using polymerase chain reaction (PCR). The results of the culture indicates that the overall occurrence of Leptospira spp in wild rodents (Rattus norvegicus) was 57.70%, with 2.62% in NAPRI Shika, 2.85% in Angwan Rimi, 3.60% in Hunkuyi, 5.24% in Bomo, 8.52% in Bassawa 15.74% in Panhauya and 19.01% in Goruba respectively. The molecular characteristics of Leptospira spp. in the study location as indicated by distinct bands showed expected band size (423bp) indicative of pathogenic Leptospira spp. In conclusion, wild rodents may be source of infection to other domestic animals and man in Zaria and its environs evident from the high prevalence observed in this study, hence, raises serious public health concern.

Abstract
Black spruce (Picea mariana Mill. B.S.P.), is a dominant species emblematic of eastern Canada's boreal forests. It grows in a vast array of climatic conditions ranging from cold maritime-oceanic climates near the Labrador Sea shore to cold continental conditions in the central portions of Quebec-Labrador. However, along the continentality gradient, timing and provenance of heat and moisture that support growth are uncertain, weakening our capacity to describe and predict the response of boreal ecosystems to climate variability. Here, we measured oxygen isotope composition in tree-ring cellulose of black spruces from three sites, and provide evidence of a direct influence of the Labrador Sea on adjacent continental ecosystems. Our results report a landwards decrease in δ18Otrc, a pattern that is also visible in the simulated oxygen isotope composition of precipitation water (δ18Op). We also reveal a landwards decoupling between δ18Otrc variability (1950-2013) and maximum temperature (Tmax) variations over the Northwest Atlantic. Our results imply that tree-ring oxygen isotopes may be of great help to circumscribe the spatial extent of Labrador Sea's influence on surrounding boreal ecosystems. Moreover, our study reveals that despite of their apparent ecological homogeneity, eastern Canada’s black spruce forests clearly rely on heterogeneous sources of heat and moisture.

Abstract
Little is known as to whether there may be any pathogenetic link between pulmonary carcinoids and neuroendocrine carcinomas. An eight-gene signature with copy number variations (CNVs) in neuroendocrine neoplasms (NENs), namely MEN1, MYC, MYCL1, RICTOR, RB1, SDHA, SRC and TP53, was used to classify an independent cohort of 54 surgically resectable tumors [31 typical carcinoids (TC), 11 atypical carcinoids (AC) and 12 small cell lung carcinomas (SCLC)], for which transcriptome and mutation data were available. Unsupervised clustering analysis identified two histology-independent clusters, namely CL1 and CL2, where 17/42 (40.5%) carcinoids and all the SCLC samples fell into the latter. CL2 carcinoids affected survival adversely, were enriched in T to G transversions and T>C/C>T transitions in the context of specific mutational signatures, presented with at least 1.5-fold change (FC) increase of gene mutations including TSC2, SMARCA2, SMARCA4, ERBB4 and PTPRZ1, differed for gene expression and showed epigenetic changes in charge of MYC and MTORC1 pathways, cellular senescence, inflammation, high- plasticity cell state and immune system exhaustion. Similar results were also confirmed in an independent validation set of 101 lung NENs (24 carcinoids, 21 SCLC and 56 LCNEC). We herein propose an unexpected shifting to the current pathogenesis paradigm, suggesting that some NECs could secondarily originate from a subset of genomically transformed carcinoids prone to epigenetic mechanism-driven progression.

Abstract
Organic light-emitting diodes (OLEDs) exploiting simple binary emissive layers (EMLs) blending only emitters and hosts have natural advantages in low-cost commercialization. However, previously reported OLEDs based on binary EMLs hardly simultaneously achieved excellent comprehensive performances, e.g., high efficiency, low efficiency roll-off, narrow emission bands, and high operation stability, which limits their commercialization. To overcome the above long-standing bottleneck, one of the key drivers is to design novel OLED emitter molecules. Here, we thus report a novel molecular-design strategy, i.e., hybridization of organoboron-nitrogen and carbonyl (named h-BNCO). Such a strategy leads to a fast rate of reverse intersystem crossing (RISC) in our newly designed h-BNCO-1 emitter, over 1×106 s-1, which is among the fastest RISC rates in multi‐resonance (MR) emitters and also comparable with those in MR molecules with heavy atoms. The OLED exploiting an EML with h-BNCO-1 achieves not only ultrapure emission with a full width at half maximum of 39 nm but also a maximum external quantum efficiency of over 40% and a mild roll-off of 14% at a practical brightness of 1000 cd·m-2. Importantly, our OLED with such binary EML exhibits good stability (the measured LT95 ~ 137 h for 1000 cd m−2). Here, our work has thus provided not only the h-BNCO molecular-design strategy that goes beyond the previous one for OLEDs with excellent comprehensive performance but also a new chemical template for the design of more novel h-BNCO molecules, thus paving the way to low-cost commercialization of high-efficiency, narrow-band, and high-stability OLEDs.
Objective assessment of postural instability in Parkinson’s disease under dynamic conditions

Published: March 2023

Abstract
Postural instability is considered one of the most incapacitating motor symptoms and a primary cause of falls in Parkinson’s disease (PD), compromising the autonomy and well-being of people suffering from this condition. Usually, the clinical examination used to evaluate this symptom is the pull test since it does not require any instruments and is easy to perform. However, this test is difficult to standardize and is not sensitive to subtle but significant changes. Recent studies have shown that inertial measurement units constitute a portable and cost-effective solution to measure postural sway, which provides metrics sensitive to balance disorders as postural instability. Further studies are required to monitor patients’ postural conditions and implement an adequate treatment to improve postural stability, it is crucial to quantify balance under dynamic conditions. Hence, the proposed research focused on investigating the hypothesis of whether it is possible to differentiate between all the scores of the pull test through postural and gait metrics extracted from raw acceleration and angular velocity signals from the center of mass of patients with PD acquired while performing basic day-to-day tasks. A cross-sectional study was followed, including 23 patients, and the achieved results showed that most of the estimated metrics can differentiate the pull test scores (ρ-value≤0.048, R2≥0.513). Overall, satisfactory results were achieved as the statistical analysis revealed gait and postural metrics estimated under dynamic conditions were considered relevant to distinguish between the scores of the pull test.
Disrupting the dorsolateral prefrontal cortex attenuates the difference in decision-making for altruistic punishment between the gain and loss contexts

Published: March 2023

Abstract
Altruistic punishment are primary responses to social norms violations, its neural mechanism has also attracted extensive attention from researchers. In the present studies, we applied a low-frequency repetitive transcranial magnetic stimulation (rTMS) to the bilateral dorsolateral prefrontal cortex (DLPFC) while participants engaged in a modified Ultimatum Game (UG) (Study 1) and a modified third-party punishment game (Study 2) to probe the neural mechanisms affecting decision-making in altruistic punishment. Normally punishers intervene more often against and show more social outrage towards Dictators/Proposers who unfairly distribute losses than rather those who unfairly share gains. We found that disrupting the function of the left and right DLPFC with rTMS effectively obliterated this difference, making participants punish unfairly shared gains as often as they normally would punish unfairly shared losses. The inhibition of the DLPFC function will lead to the deviation of individual information integration ability and influence the moderating effect of gain and loss contexts on altruistic punishment. Our findings emphasize that DLPFC is closely related to altruistic punishment and provide causal neuroscientific evidence.
Technological analysis of lithic assemblages from surface collections. First evidence of a Palaeolithic frequentation of the Po plain in Piedmont: the case of Trino (north-western Italy)

Published: March 2023

Abstract
The Trino hill is an isolated relief located in north-western Italy, close to Trino municipality. The hill was subject of multidisciplinary studies during the 70s, when, because of quarry activities and agricultural arrangements, five concentrations of lithic artefacts were recognized and referred to a Palaeolithic frequentation of the area. During the 80s and the 90s, surface collections continued, but the lithic finds have never been subject of specific studies. Even if most of the lithic assemblages count a few lithic implements, four collection areas (3, 13 E, 13 W and 14) have significative lithic assemblages, representing the most important evidence of a Palaeolithic frequentation of the Po plain in north-western Italy. The present work, in the limits imposed by a surface and not systematic collection, propose a technological study of the lithic artefacts from the Trino hill, with the aim to define the main features of the technological behaviour of the human groups that inhabited the area. The results obtained allow to clearly identify a Middle Palaeolithic frequentation of the Trino hill, characterized by the exploitation of vein quartz and other local raw materials; allochthonous varieties of chert were used in the next frequentation phases to produce blades and bladelets. Even if part of the laminar production can be referred to Neolithic, most of that remains of indeterminate chronology and could be the result of both an Upper Palaeolithic and Neolithic human presence.

Abstract
Objective: This study aimed to examine the mediating role of anxiety and depression on the relationship between coping styles and life satisfaction in medical workers during the COVID-19 pandemic.
Methods：Five hundred and fourteen frontline medical workers from Zunyi were recruited to complete questionnaires, including the Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Satisfaction With Life Scale (SWLS), and Simplified Coping Style Questionnaire (SCSQ).
Results：The results revealed the following: a) The prevalence of anxiety was 22.57%, and the prevalence of depression was 18.29%. b) Anxiety was positively correlated with depression; anxiety and depression were positively correlated with passive coping styles but negatively correlated with life satisfaction and active coping styles; life satisfaction was positively correlated with active coping styles and negatively correlated with passive coping styles. c) Anxiety and depression partially mediated the relationship between active coping styles and life satisfaction.
Conclusion：Some frontline medical workers in the pandemic area had subclinical anxiety and depression, and anxiety and depression had a mediating effect on the relationship between coping styles and life satisfaction.

Authors: Leiva Tyler , Golubkova Alena , Snyder Katherine , Johnson Jeremy , Hunter Catherine J. 
Published: March 2023

Abstract
Purpose: Traumatic lumbar hernias (TLH) are a rare entity mostly seen with high impact, blunt abdominal trauma (BAT). This injury occurs when there is disruption of the posterior musculature along with bony structures, allowing for herniation of abdominal contents. There are minimal cases of this entity reported in adults, but even fewer in the pediatric population.
Methods: We describe 3 cases of TLH at our institution as well as provide a review of the literature to elucidate the most common mechanisms, severity of injury, and associated injuries.
Results: TLH is most commonly seen in restrained passengers involved in motor vehicle collisions (MVC). The majority of cases are diagnosed using computed tomography (CT) imaging, and less frequently during primary surgical exploration. The most common associated injuries were mesenteric and bowel injuries, followed by spinal and chest trauma. TLH often leads to prolonged hospital stays and increased need for post-hospital rehabilitation due to associated traumatic comorbidities.
Conclusion:TLH is a rare entity in children and early suspicion and identification of associated injuries is necessary in the management of these patients

Published: March 2023

Abstract
Let H be a Hopf algebra. The concept of symmetry of a quasitriangu-lar structure on H is introduced and some properties of a symmetric quasitriangular structure are characterized. We apply this to study quasitriangular structures on small quantum groups and abelian extensions. In particular, the quasitriangular structures on uq(sl2) (if they exist) are proved to be symmetric and all quasi-triangular structures on K(8n, σ, τ), which is a generalization of the well-known 8-dimensional Kac algebra, are determined.
