Abstract
Background
Venous thromboembolism (VTE) is a severe preventable complication among ophthalmic surgical patients. The knowledge, attitude, and practice (KAP) of nurses play a key role ineffective VTE prevention. However,little is known about the KAP of ophthalmic nurses’ prevention. This study aimed toexamine the level of KAPtoward VTE prevention among Chinese ophthalmic nurses, and to investigate the influencing factors of VTE practice.
Design
Cross-sectional study.
Methods
A total of 610 ophthalmic nurses from 17 cities in Hunan and Zhejiang Provinces, China, participated in our study. Data was collected via Sojump online platform from March to April 2021. A self-administered VTE questionnaire was developed to assess nurses' KAP toward VTE prevention. Multiple linear regression analysis was used to analyze the influencing factors of ophthalmicnurses’ VTE prevention practice.
Results
The scores (correct rates) of ophthalmic nurses’ knowledge, attitude, and practice were 103.87 ± 20.50 (76.4%), 21.96 ± 2.72, and 48.96 ± 11.23 (81.6%), respectively. The three lowest-scored knowledge items were related to VTE complications, physical prevention, and risk assessment. The three lowest-scored attitude items were related to nurses' training, VTE risk, and patient education. The three lowest-scored practice items were related to the assessment scale, VTE assessment, and patient education. Nurses’ knowledge, attitude, and practice were significantly correlated with each other. Multiple linear regression analysis showed that Hunan Province (B = 2.77, p = 0.006), general hospital (B = 2.97, p = 0.009), outpatient department (B = 3.93, p = 0.021), inpatient department (B = 2.50, p = 0.001), previous VTE prevention training (B = 3.46, p < 0.001), VTE prevention management in hospital (B = 4.93, p < 0.001), better knowledge (B = 0.04, p = 0.038), and positive attitude towards VTE prevention (B = 1.35, p < 0.001) were all significantly and positively associated with higher practice scores in VTE prevention.
Conclusion
Ophthalmic nurses generally have a satisfactory level of KAP in VTE prevention, but there is still room for improvement in certain areas. Nurses’ practice in VTE prevention was affected by environmental factors, training and management, knowledge and attitude, which may inform future intervention and education programs to improve VTE prevention.

Abstract
Dominance hierarchy, is described as the priority to feed, resting and territory in term of aggressive interactions. Increased studies have revealed the underpinned mechanism mediating social hierarchy in mammal, vertebrate and fishes, however, there is rare studies conducting on how brain amydala on social hierarchy in poultry. We performed cross-species analysis with mammalian amygdala, and find that cell types of human and rhesus monkeys were more closely related and that of chickens were more distant. We identified 26 clusters and divided it into 10 main clusters. Of which, GABAnic and glutamatergic neurons are associated with social behaviors, and their sub-neurons GABA_LEG and Glu3, and hub genes RHOB and CDK14, are considered mediating the social hierarchy of chickens. Additionally, high-rank chickens may have better immune functions and stress tolerance than low-rank chickens. Our results provide to serve the developmental studies of amygdala neuron system, and new insights into the underpinned mechanism of social hierarchy in poultry.

Published: May 2023

Abstract
The high energy density of Si makes it a preferred anode material for lithium-ion batteries. However, the low conductivity and large volume changes associated with the charging and discharging processes lead to a rapid decay in capacity during cycling, which hinders its commercialization. In this study, micron-scale PSi@PEDOT/GO composites were prepared by coating commercial Al–Si alloys with poly 3,4-ethylenedioxythiophene (PEDOT) and graphene oxide (GO) using in situ polymerization and freeze-drying methods. The core layer of the PSi@PEDOT/GO composite has abundant internal pores to provide sufficient space to adapt to the volume change of silicon, whereas the PEDOT and GO coating layers can accelerate the ion and electron transport and accommodate the volume change of silicon, which can effectively improve the cycling stability and rate performance of the silicon anode. The characterization results show that the PSi@PEDOT/GO-2 (mass ratio = 6:4:5) composite electrode material has a specific capacity of 1102.30 mAh/g after 100 cycles. When the current density is 0.3A/g, the specific capacity is still 1102.30 mAh/g after 100 cycles, and the capacity retention rate is 75.8%. In addition, it exhibits a specific capacity of 406.87 mAh/g at a current density of 4 A/g, indicating excellent cycling and rate performance and good application prospects.

Abstract
Individuals may add to their behavioural repertoire by observing conspecifics, and possibly heterospecifics. Here we test Darwin’s intriguing hypothesis that honey bees rob nectar from flowers after observing the behaviour of other bees. We trained naïve honey bees to forage for sucrose by entering the flower-tube opening of custom designed 3D-printed model flowers before exposing individual bees to experimental flowers. In these flowers, nectar could only be accessed via a small hole at the base of the corolla tube, thereby simulating secondary nectar-robbing. Bees had to change their foraging behaviour from foraging via the mouth of the flower to foraging from the tube-base to rob. Different demonstrators were used to indicate the presence of a robbing hole. To explore the efficiency of information transfer from different demonstrators, we moved dead conspecific and heterospecific (carpenter bees and crickets) demonstrators towards this small hole to imitate nectar robbing. Differences in the ability and speed of honey bees to imitate robbing behaviour were recorded for each demonstrator treatment. Naïve honey bees switched to robbing behaviour more frequently when observing honey bee and carpenter bee demonstrators than when observing cricket demonstrators or controls that lacked a demonstrator. However, honey bees switched to robbing behaviour significantly faster after observing conspecifics than after observing any other demonstrators. This study demonstrates that honey bees can gather information from conspecifics and even heterospecifics while foraging, which can influence foraging behaviour such as flower robbing. Utilizing foraging cues from other individuals may lead to conspecific and heterospecific learning.
“I can hardly doubt they [honeybees] were profiting by the workmanship and the example of the humble-bees: should this be verified, it will, I think, be a very instructive case of acquired knowledge in insects.” Darwin 1841

Abstract
Background:Percutaneous vertebroplasty（PVP）has become one of the main methods for the treatment of osteoporotic thoracolumbar vertebral compression fractures. There is still lack of medium term data on the long-term outcome comparisons between unilateral and bilateral approach.
Objective: To compare the efficacy of unilateral and bilateral approach Percutaneous vertebroplasty（PVP）in the treatment of elderly patients with osteoporotic vertebral compression fractures( OVCF).
Methods: One hundred and ninety-three patients with symptomatic osteoporotic vertebral compression fractures (OVCF) treated with PVP were retrospectively reviewed in a single institution.Patients were divided into Group A(unilateral approach) and Group B(bilateral approach), based on operative approach. The efficacy was evaluated by perioperative indicators, follow-up results and imaging evaluation.All computations were performed with standard software (SPSS version 22.0 for Windows; IBM).
Results：One hundred and sixtyty-nine of 193 eligible patients were included. All the patients received the follow-up visits for 49-70 months.In this case, there were no serious postoperative complications.A significant difference was found between group A and group B in terms of operation time，puncture time，amount of bone cement injected，the number of X-ray fluoroscopy (P < 0.05). the difference in the incidence of cement leakage between the two groups was not statistically significant (P > 0.05)，and the length of hospitalization and hospital costs in group A were lower than those in group B was not statistically significant (P > 0.05).The time of postoperative mobilization was(3.00 ±0.80)weeks in group A and(3.60 ± 0.79)weeks in group B，The difference was statistically significant (P < 0.05).As VAS and ODI scores, the short-term efficacy of the group A was worse than that of the group B, but the difference between the two groups was smaller at the final follow-up(P > 0.05). In terms of imaging evaluation, there were no significant differences between the two groups(P > 0.05).
Conclusions: All patients were assessable for safety and efficacy. At the final follow-up, both groups showed significant improvements in the height of the height of the vertebral body and Cobb's angle of kyphosis (P < 0.05).Changes in VAS after PVP, the preoperative pain reduced significantly. Unilateral approach resulted in less blood loss intraoperatively, a shorter operation time, and less number of fluoroscopy(P > 0.05).However, There were no significant differences in the symptomatic scores at the last follow-up.

Abstract
Background Chronic Kidney Disease of unknown cause (CKDu) a disease of exclusion, and remains unexplained in various parts of world including India. Previous studies have reported mixed findings about the role of heavy metals or agrochemicals in CKDu. These studies compared CKDu with healthy controls, but lacked subjects with CKD as controls. The purpose of this study was to test hypothesis whether heavy metals i.e. Arsenic (As), Cadmium (Cd), Lead (Pb) and Chromium (Cr) are associated with CKDu, in central India.Methods The study was conducted in case-control manner at a tertiary care hospital. CKDu cases (n = 60) were compared with CKD (n = 62) and healthy subjects (n = 54). Blood and urine levels of As, Cd, Pb and Cr were measured by Inductively Coupled Plasma- Optical Emission Spectrometry. Pesticides use, pain killers, smoking and alcohol addiction were also evaluated. The median levels of blood and urine metals were compared among the groups by Kruskal-Wallis rank sum test.Result CKDu had significantly higher pesticide use. Blood As levels (median, IQR) were significantly higher in CKDu 91.97 (1.3-132.7) µg/L compared to CKD 4.5 (0.0-58.8) µg/L and healthy subjects 39.01 (4.8–67.4) µg/L (p < 0.001). Urine Cd was higher in CKD 1.0 (0.3–1.7) µg/L compared to CKDu 0.5 (0.0-1.5) µg/L with a trend (p-0.06) of significance. Blood and urinary Pb and Cr were higher in CKD compared to CKDu (P = 0.5). Urinary Cd, Pb and Cr were undetectable in healthy subjects and were significantly higher in CKDu and CKD compared to healthy subjects (P = < 0.001).Conclusion The study showed a significant association of As with CKDu and a trend of association of Cd with CKD in this Indian cohort. Subjects with renal dysfunction (CKDu and CKD) have significantly higher metal burden of Pb, Cd, As, Cr as comparedto healthy controls.

Abstract
Tobacco is one of the most economically important non-food crop in Zimbabwe and other tobacco producing countries globally. Currently, little is known about the genetic diversity of tobacco germplasm in Zimbabwe. Understanding the genetic diversity of tobacco germplasm offers significant help in the selection of suitable material for breeding superior cultivars. In this study, 10 SSR markers were employed to assess the genetic diversity and population structure of 93 tobacco breeding lines and cultivars. A total of 50 alleles on 10 SSR loci were detected and the allele number per loci ranged from 3 to 14. The average gene diversity index and average polymorphism information content (PIC) ranged from 0.53 and 0.48, respectively, showing low levels of genetic diversity among tobacco cultivars. The AMOVA result revealed a low level of differentiation among accessions from different origins. Based on SSR markers, the tobacco germplasm collections consistently showed very low levels of genetic differentiation using the Bayesian statistical analysis, cluster analysis and principal coordinate analysis consistently revealed the lack of differentiation among the germplasm collections. The genetic characterization of tobacco germplasm in seed bank repositories could be very useful for monitoring and preventing further genetic erosion andpreventing excessive inbreeding in new variety development.
Welfare Effects of Implicit Auction on Interconnector Capacity: Evidence from Japan
Authors: Sugimoto Kota 
Published: May 2023

Abstract
This study examines the welfare impact of implicit auction on the interconnector transmission capacity in Japan. The first-come-first-served rule allows incumbent generation or retail firms to exercise vertical market power by withholding the interconnector capacity and create congestion in the day-ahead market. The implicit auction allocates all the capacity simultaneously with energy in the day-ahead market. It prevents them from strategically reserving their physical transmission capacity ex ante and increases cross-zonal trade volumes in the day-ahead market. Increased trade reduces the price gap between the import and export zones. I use machine-learning methods to estimate the welfare impact of implicit auction. I predict the counterfactual market outcomes without implicit auction, and find that the trade effect of implicit auction is over $ 200 million per year. The study also finds that implicit auction does not necessarily reduce the price gap between export and import zone because it not only has a trade effect but also a counteracting volume effect.

Abstract
A novel negative-stranded RNA mycovirus was isolated from the phytopathogenic fungus Fusarium sibiricum strain AH32. This virus, tentatively named Fusarium sibiricum coguvirus 1 (FsCV1), has a bipartite genome consisting of two RNA segments (RNA1 and RNA2). The negative-sense RNA1 is 6737 nt in length, encoding the RNA-dependent RNA polymerase (RdRp, p251) in the viral complementary (vc) strand. The ambisense RNA2 (1232 nt long) encodes two overlapping proteins: the nucleocapsid protein (NP, p38) in the vc strand and an unknown function protein (UFP, p36) in the viral (v) strand, different from the typical features of Bunyavirales members: the two open reading frames are separated by a long AU-rich intergenic region (IR). Phylogenetic analysis based on the RdRp demonstrated that FsCV1 belongs to the genus Coguvirus, family Phenuiviridae, order Bunyavirales. This is the first report of a coguvirus infecting a fungus.

Abstract
This study investigated the physiological characteristics and fluorescence reflection of Field bindweed after exposure to various doses of Clopyralid alone or in combination with salicylic acid. High doses of Clopyralid increased the concentrations of malondialdehyde and hydrogen peroxide, while decreased the activities of antioxidant enzymes. High concentrations of this herbicide also decreased the amount of protein and photosynthetic pigments but increased the proline content compared to the control treatments. Applying SA three days before Clopyralid spraying intensified oxidative stress and lipid peroxidation due to the disruption of the plant's hormonal balance as a result of the use of high dose of SA. PSII performance index was reduced under Clopyralid + SA. Field bindweed photosynthetic apparatus was further altered after SA application three days before Clopyralid spraying. This study highlighted that, for a better use of Clopyralid, the use of SA could be beneficial, not only for the herbicide efficacy against field bindweed weed, but also for the environment due to lower applied doses of herbicide.

AbstractThe treatment of cancer-associated stroke is determined based on stroke etiology; however, the optimal treatment and therapeutic benefits remain unclear. We aimed to evaluate the clinical and functional outcomes of patients with cancer and acute ischemic stroke, especially focusing on patients with cryptogenic stroke. We retrospectively reviewed consecutive cancer patients diagnosed with acute ischemic stroke at our institution between January 2018 and December 2019. Stroke subtype, cancer treatment after stroke, modified Rankin Scale (mRS) scores before and at ischemic stroke, 3 months after ischemic stroke or last follow-up, and discharge destination were evaluated. We analyzed 48 cancer patients with acute ischemic stroke, including 24 with cryptogenic stroke and 24 with known stroke mechanisms. The median survival time of the patients was 62 days. Thirty-one patients (64.6%) discontinued cancer treatment after stroke. Forty patients (83.3%) and 37 (77.1%) were in poor functional states (defined as mRS score ≥ 3) at stroke onset and 3 months after stroke or last follow-up. Twenty-two patients (91.7%) with cryptogenic stroke discontinued cancer treatment after stroke, whereas 15 patients (62.5%) with known stroke mechanisms continued cancer treatment (p = 0.0004). Home or rehabilitation hospital discharge destinations were less frequently seen in patients with cryptogenic stroke (n = 7, 29.2%) than those with known stroke mechanisms (n = 15, 62.5%, p = 0.021). Stroke has a significant negative impact on patients’ functional states and cancer treatment strategy, leading to short survival times, especially in patients with cryptogenic stroke.

Abstract
Purpose The number of older adult patients with uterine cervical cancer is continuously increasing in Japan. This study aimed to investigate the patient characteristics, treatment outcomes, and adverse effects (AEs) of older adult patients with cervical cancer.Methods We retrospectively analyzed 89 patients who had undergone definitive radiation therapy (RT). Based on patient age at the time of study inclusion, patients were divided into the older (≥ 75 years [n = 21]) and younger (< 75 years [n = 68]) adult groups, between which the patient characteristics and three-year cumulative overall survival (OS) and progression-free survival (PFS) rates were compared. We assessed potential prognostic factors, the association between reductions in Eastern Cooperative Oncology Group (ECOG) performance status (PS) before treatment and six months post-treatment, and treatment-related factors.Results Histological type (adenocarcinoma) was associated with OS, whereas average Hb concentration during treatment was associated with PFS in older adult patients. Moreover, the external beam RT field, concurrent chemotherapy dose, and overall treatment time were not associated with a worsening of ECOG PS among older adult patients. Acute AEs of grade ≥ 3 were significantly more common in the younger adult group; however, three of the older adult patients (14%) had Grade 3 leukopenia, and two were concurrently receiving ≥ 200 mg of cisplatin.Conclusion Concurrent chemoradiation therapy may cause severe leukopenia in older adult patients; therefore, it should be considered carefully in older adult patients with cervical cancer.
