Published: July 2021

Abstract
Trees in general are very tolerant of aluminum (Al, mainly Al3+ at pH ≦ 5.0), and the small effects seen in the contaminated soils may mislead people that the contamination is unimportant. We believe that the assessments with Al-sensitive Masson pine could have revealed a bigger difference. The key point of this study was to characterize the Al toxicity for Masson Pine. The objectives were to discover the specific eco-physiological relationship between pine roots and rhizosphere Al, and to investigate the Al effects on several parameters, measured in the rhizosphere of Masson pine. Masson pine seedlings were cultivated on a hydroponic setup. Through comprehensive laboratory dose-gradient experiments, Al-triggered composition of the root-released compounds and several rhizospheric parameters were determined by chromatography or spectroscopy. This study gives an important evidence of the Al-toxicity effects on the composition of root-released compounds and the root growth of Masson pine. Results showed that higher rhizospheric Al at pH 4.5 might contribute to increased release of sugars, and also could stimulate the release of oxalic acid and malic acid. The total of secreted amino acids were correlated with the rhizosphere Al. Zero additional Al induced no rhizosphere pH elevation, but Al-induced rhizosphere acidification (pH from 4.50 to 4.22) was observed at Al 100 µM. Greater additions of Al (>300 µM) suppressed the rhizosphere acidification at pH 3.92. Added Al had a negative effect on the dry weight of pine roots, but an opposite effect on Al accumulated in the roots was observed. The four endogenous hormones were also determined in the pine roots. Gibberellic acid (GA3) decreased, whereas abscisic acid (ABA) increased simultaneously with the addition of Al. Their inflexional concentrations were most frequently observed at 100 µM, which might be the threshold of Al toxicity for Masson pine. The secondary metabolites assayed have been studied in relation to the rhizospheric Al. The rhizosphere Al species at low pH can trigger pine roots to release the sugars (glucose, fructose + aldose), organic acids (oxalic acid, and malic acid), amino acids, secondary metabolites, and endogenous hormones during their growth. Meanwhile it also affected the growth of pine roots. This is an extensive study, which can help understanding the toxicity of Al to this important pioneer species of acid forest soils in south China.

Abstract
Purpose: Although psychosocial services have substantial impact in cancer care, the availability and utilization of these services have not been well-studied in Sub Saharan Africa. Therefore, we explored the types of psychosocial services available for breast cancer patients in Addis Ababa, Ethiopia.Methods: A mixed method study was conducted using a cross-sectional survey involving 428 breast cancer patients, followed by a qualitative study. A total of nine in-depth interviews (IDIs) were conducted with four breast cancer patients and five key informants using two separate interview guides. In addition to descriptive statistics, logistic regression was done to identify factors associated with provision of psychosocial services. Thematic analysis was used for the qualitative data using NVivo 12 plus software. Results: Only 47 (11.1%) patients received psychosocial services, either in the form of counseling, emotional support or provision of information. Health professionals reportedly provided such services along with their routine activities, and patients predominantly received social/emotional support from family members, friends and colleagues. There were no well-structured counseling service, emotional support or group discussion sessions for breast cancer patients in these health facilities. The main reasons for not providing these services were high patient flow/workload, inadequate space, lack of training and not having qualified professionals to organize and deliver psychosocial services in those hospitals.Conclusions: only one in ten breast cancer patients received psychosocial services from health professionals, and the services were not delivered in a structured way. Therefore, psychosocial services should be integrated both in private and government health facilities of Ethiopia.

Abstract
SARS-CoV-2 remains a global threat to human health particularly as escape mutants emerge. There is an unmet need for effective treatments against COVID-19 for which neutralizing single domain antibodies (nanobodies) have significant potential. Their small size and stability mean that nanobodies are compatible with respiratory administration. We report four nanobodies (C5, H3, C1, F2) engineered as homotrimers with pmolar affinity for the receptor binding domain (RBD) of the SARS-CoV-2 spike protein. Crystal structures show C5 and H3 overlap the ACE2 epitope, whilst C1 and F2 bind to a different epitope. Cryo Electron Microscopy shows C5 binding results in an all down arrangement of the Spike protein. C1, H3 and C5 all neutralize the Victoria strain, and the highly transmissible Alpha (B.1.1.7 first identified in Kent, UK) strain and C1 also neutralizes the Beta (B.1.35, first identified in South Africa). Administration of C5-trimer via the respiratory route showed potent therapeutic efficacy in the Syrian hamster model of COVID-19 and separately effective prophylaxis. The molecule was similarly potent by intraperitoneal injection.

Abstract
Ultraviolet C (UVC), or ultraviolet germicidal irradiation, is known for its effective air, water, and surface disinfectant properties. With the rise of global awareness about public sanitation and personal hygiene due to the emergence of the current coronavirus disease 2019 pandemic, several applications of UVC were introduced to the commercial market. The present experimental study aimed to evaluate the effectiveness of commercial household ultraviolet C germicidal devices for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inactivation. UVC dosages (mJ/cm2) of 10 UVC devices were determined at the recommended settings compared to a benchmark for SARS-CoV-2 inactivated UVC dosage (3.7 mJ/cm2). Of the 10 devices, 3 were handheld UVGI surface disinfection equipment, 4 were UVGI disinfection chambers, and 3 were movable UVGI air and surface purifiers. Three UVGI disinfection chambers and all movable UVGI air and surface purifiers provided sufficient UVC dosages for SARS-CoV-2 inactivation. None of the studied handheld UVGI surface disinfection equipment achieved the UVC dosage for SARS-CoV-2 inactivation. A lack of standardization in the distance and cycle duration for each UVC application was observed. Standard usage guidelines for UVC devices are required to improve the effectiveness of UVC irradiance for SARS-CoV-2 inactivation and minimize the potential side effects of UVC.

Abstract
A Gram-negative, rod-shaped, motile and strictly aerobic bacterium, designated NBU1469T, was isolated from marine sediment sampled on Meishan Island located in the East China Sea. Strain NBU1469T grew optimally at temperature of 40ºC, NaCl concentration of 2.0% (w/v) and pH 7.5. Catalase and oxidase activities, H2S production, nitrate reduction and hydrolysis of Tween 20 were positive. Indole, methyl red reaction, urease, hydrolysis of gelatin, starch, casein, Tweens 40, 60 and 80 were negative. The major cellular fatty acids were C16:0, C19:0 cyclo ω8c and summed feature 8 (C18:1 ω7c and/or C18:1 ω6c). The only respiratory quinone was ubiquinone-10 (Q-10). The major polar lipids were phosphatidylglycerol, two unidentified amino-phospholipids and two unidentified phospholipids. Comparative analysis of the 16S rRNA gene sequence showed highest similarities to the species with validated name Nisaea nitritireducens DR41_18T (98.1%) and Nisaea denitrificans DR41_21T (97.6%). Phylogenetic analyses indicated that strain NBU1469T formed a distinct lineage with strains Nisaea nitritireducens DR41_18T and Nisaea denitrificans DR41_21T within the genus Nisaea. The average nucleotide identity and digital DNA-DNA hybridization values between strain NBU1469T and related species of genus Nisaea were well below the threshold limit for prokaryotic species delineation. The DNA G+C content was 63.6 mol%. Based on its phenotypic, chemotaxonomic and genotypic data, strain NBU1469T is considered to be a representative of a novel species in the genus Nisaea, for which the name Nisaea sediminum sp. nov. is proposed. The type strain is NBU1469T (=KCTC 82224T=MCCC 1K04763T).

Abstract
Background: Delayed or misdiagnosed aortic dissection can lead to death and morbidity. Ischemia-modified albumin (IMA) measures the cobalt binding capability and has been associated with mortality in patients with acute aortic dissection (AAD). However, it is unknown whether IMA levels can differentiate AAD in patients with chest pains.Methods: A total of 100 suspected AAD patients were enrolled in this study. A cobalt-binding assay was used to determine the plasma IMA levels. In addition, the IMA levels of patients in different groups were compared based on the final diagnosis. Results: IMA levels were significantly higher in the AAD group than in the AMI, PE, and other groups (63.98 ± 14.38, 52.57 ± 9.54, 49.26 ± 10.99, 37.99 ± 6.59, respectively) within 24 hours after the onset of symptoms. The area under the curve (AUC) based on the IMA level was 0.810 (95% CI, 0.708–0.897), and the best threshold of IMA was 59.35 u/ml (specificity, 85.7% and sensitivity, 66%). The decision and clinical impact curves indicated that the IMA had an excellent standardized net benefit and could be suitable for patient diagnosis.Conclusion: IMA is elevated in AAD patients. The IMA levels have better performance for AAD than D-dimer and could be a potential biomarker with rapid and cost-effective diagnostic tests for early diagnosis of AAD. However, large-sample studies are needed to verify the findings.
Nutrient Leaching in Extensive Green Roof Substrate Layers With Different Configurations

Abstract
Due to substrate layers with different substrate configurations, extensive green roofs (EGRs) exhibit different rainfall runoff retention and pollution interception effects. In the rainfall runoff scouring process, nutrient leaching often occurs in the substrate layer, which becomes a pollution source for rainwater runoff. In this study, six EGR devices with different substrate layer configurations were fabricated. Then, the cumulative leaching quantity (CLQ) and total leaching rate (TLR) of NH4+, TN and TP in the outflow of nine different depth simulated rainfall events under local rainfall characteristics were evaluated and recorded. Furthermore, the impact of different substrate configurations on the pollution interception effects of EGRs for rainfall runoff was studied. Results show that a mixed adsorption substrate in the EGR substrate layer has a more significant rainfall runoff pollution interception capacity than a single adsorption substrate. PVL and PVGL, as EGRs with layered configuration substrate layers, exhibited good NH4+-N interception capacity. The CLQ and TLR of NH4+-N for PVL and PVGL were -114.613 mg and -63.43%, -121.364 mg and -67.16%, respectively. Further, the addition of biochar as a modifier significantly slowed down the substrate layer TP leaching effect and improved the interception effect of NH4+-N and TN. Moreover, although polyacrylamide addition in the substrate layer aggravated the nitrogen leaching phenomenon in the EGRs outflow, but the granular structure substrate layer constructed by it exhibited a significantly inhibited TP leaching effect.

Abstract
The ongoing COVID-19 pandemic represents a considerable risk for the general public and especially for health care workers. To avoid an overloading of the health care system and to control transmission chains, the development of rapid and cost-effective techniques allowing for the reliable diagnosis of individuals with acute respiratory infections are crucial. Uniquely, the present study focuses on a direct face mask sampling approach, as worn (i.e., used) disposable face masks contain exogenous environmental constituents, as well as endogenously exhaled breath aerosols. Optical techniques – and specifically infrared (IR) molecular spectroscopic techniques - are promising tools for direct virus detection at the surface of such masks. In the present study, a rapid and non-destructive approach for monitoring exposure scenarios via medical face masks using attenuated total reflection infrared spectroscopy is presented. Complementarily, IR external reflection spectroscopy was evaluated in comparison for rapid mask analysis. The utility of a face mask-based sampling approach was demonstrated by differentiating water, proteins, and virus-like particles sampled onto the mask. Data analysis using multivariate statistical algorithms enabled unambiguously classifying spectral signatures of individual components and biospecies. This approach readily extends towards the rapid detection of SARS-CoV-2 – as shown herein for the example of virus-like particles which are morphologically equivalent to authentic virus - without any additional sample preparation or elaborate testing equipment at laboratory facilities. Therefore, this strategy may be implemented as a routine large-scale monitoring routine, e.g., at health care institutions, nursing homes, etc. ensuring the health and safety of medical personnel.

Abstract
Background: High survival rate of children diagnosed with cancer has led to a growing population of women with premature ovarian failure (POF) due to chemotherapy and radiotherapy. The POF process occurs due to the disruption of the Hypothalamic-Pituitary and gonadal axis followed by the delay of puberty development. Evaluation of reproductive function in children with cancer is essential to determine the fertility preservation plan. This study aimed to describe reproductive function in children and adolescents with cancer who received chemotherapy based on Tanner stage evaluation, menstrual cycle, and Anti-Mullerian Hormone (AMH) examination using Electrochemilumiscence Immunoassay (ECLIA) Kit.Result: Twenty-three girls aged 12-18 years old and had menarche who underwent cancer therapy in January-August 2019 in Dr. Sardjito General Hospital were included in the study. Among them, 61% girls had low AMH levels and were defined as Diminished Ovarian Reserve (DOR). There were two subjects with DOR who experienced delayed puberty. Regular menstrual cycle was reported in 65.2% subjects, while 21.7% encountered secondary amenorrhea.Conclusion: Chemotherapy exposure impacted on DOR occurrence in 60.9% childhood and adolescence cancer. Moreover, it also altered menstrual regularity in 34.8% and delayed on puberty development in 8.7% subjects.

Abstract
Despite the significant volume of fiscal recovery measures announced by countries to deal with the COVID-19 crisis, most recovery plans allocate a low percentage to green recovery. We present scenarios exploring the long-term impact of the COVID-19 crisis and develop a Green Recovery scenario using three global models to analyze the impact of a more ambitious allocation. The results show that a Green Recovery scenario, with 1% of global GDP in fiscal support directed to mitigation measures for three years, could reduce global CO2 emissions by 10.5−15.5% below pre-COVID projections by 2030. The share of renewables in global electricity generation is projected to reach 45% in 2030, the uptake of electric vehicles would be accelerated, and energy efficiency in the buildings and industry sector would improve. However, such a temporary investment should be reinforced with sustained climate policies after 2023 to lead to socio-economic restructuring towards carbon neutrality by mid-century.

Abstract
Objective: To compare the recurrence rate of retinopathy of prematurity (ROP) after treatment with 0.3 mg vs. 0.25 mg ranibizumab. Subjects: All patients with ROP who underwent intravitreal injection of ranibizumab in Hainan General Hospital between January 2014 and May 2020 were included in this study. Methods: 82 cases (146 eyes) who received intravitreal injection of 0.25 mg ranibizumab were included in the conventional-dose group, and 59 cases (108 eyes) who received intravitreal injection of 0.3 mg ranibizumab were included in the high-dose group. The two groups were further divided into the 25-28-week, 29-31-week, 32-34-week, and 35-36-week GA subgroups. The differences between the conventional-dose group and the high-dose group in gestational age (GA), birth weight(BW), age at initial injection(weeks), incidence of systemic diseases, the recurrence rate of ROP, and age at retinal vascularization completed(weeks) were analyzed. Results: GA, BW, age at initial injection, and the incidence of systemic diseases were not significantly different between the conventional-dose group and the high-dose group (p>0.05). The recurrence rates of ROP were significantly lower in the 25-28-week, 29-31-week, and 32-34-week subgroups of the high-dose group than in the same subgroups of the conventional-dose group (p<0.05). Within the conventional-dose group, the recurrence rate of ROP was significantly lower in the 32-34-week and 35-36-week subgroups than in the 25-28-week and 29-31-week subgroups (p<0.05). Within the high-dose group, the recurrence rate of ROP was not significantly different between the four subgroups (p>0.05). Retinal vascularization was completed at a later age in the 32-34-week subgroup of the high-dose group than in the 32-34-week subgroup of the conventional-dose group (p<0.05) but was not significantly different between the two groups at any other GA range (p>0.05). No severe ocular or systemic complications occurred in any patient. Conclusion: Treatment with 0.3 mg ranibizumab can reduce the recurrence rate of ROP without prolonging retinal vascularization or causing serious systemic complications. Therefore, this dose may be an appropriate therapeutic dose for ROP.

Abstract
The role of β-catenin and Dickkopf-1 (DKK1) is dependent on the specific immunobiology of T cell inflammation in biliary tract cancer (BTC). We aimed to analyze the role of DKK1 or β-catenin as a prognostic factor in BTC, and determine the clinical associations of ß-catenin and DKK1 with CD8 + tumor-infiltrating lymphocytes (TIL). We used data from The Cancer Genome Atlas Research Network and the clinicopathological data of 145 patients with BTC who had undergone primary radical resection between 2006 and 2016. CD8 + TIL expression was a significant predictor of favorable overall survival (OS) and relapse-free survival (RFS) (median OS, 34.9 months in high-TIL, 16.7 months in low-TIL, P < 0.0001 respectively; median RFS, 27.1 months in high-TIL, 10.0 months in low-TIL, P < 0.0001 respectively). In the high-CD8 + TIL BTC group, the tumor expression of β-catenin and DKK1 had a significant negative impact on either OS or RFS. In the low-TIL BTC group, there were no differences according to ß-catenin and DKK1 expression. Cox regression multivariate analysis demonstrated that CD8 + TIL and β-catenin retained significant association with OS. Among patients with resected BTC, the β-catenin and DKK1 protein and high CD8 + TIL levels were associated with poor and good clinical outcomes, respectively.
