Abstract
Two novel cobalt(II) tetraphenylporphyrin-based six-coordinate complexes; bis(4-Dimethylaminopyridine)(5,10,15,20-tetrakis[4-bromophenyl]porphinato) cobalt(II) (1) and bis(4-Dimethylaminopyridine) (5,10,15,20-tetrakis[4-chlorophenyl]porphinato )cobalt(II) (2) were synthesised in good qualitative and quantitative yields. The chemical structures of these synthesized compounds were confirmed by elemental analysis, infrared, proton nuclear magnetic resonance and mass spectrometry, UV–vis absorption, and fluorescence spectroscopies. Their photophysical properties, namely their molar extinction coefficients (ε), fluorescence quantum yields (Φf) and lifetimes (τf), were determined and compared with those of meso-tetraphenylporphyrin. The dielectric properties such as dielectric constant (ε′), dielectric loss (ε″), and conductivity (σ) were investigated as a function of temperature and frequency. Impedance analysis was carried out using Cole-Cole plots to understand the electrical conduction mechanism. As an application of our two cobaltous complexes, an investigation involving complexes 1–2 in the photocatalytic performance was carried out by decomposing the TB dye under visible light irradiation at room temperature.

Published: April 2023

AbstractDeveloping the high-capacity anode materials such as conversion-type metal oxides which possess both Li and Na storage activity is very practical for the high-energy LIBs/SIBs. Herein, we use NiCo2O4anodes as a model to investigate the morphology evolution which accounts for the poor cycling performance and understand the effect of structure optimization on the electrochemical performance. Three NiCo2O4samples with different morphologies of microspheres, nanospheres and nanosheets are synthesized. Firstly, the serious structural degradation of NiCo2O4microspheres is observed whether it works as a LIB or SIB anode. In addition, a significant difference between the lithiation and sodiation capacity of NiCo2O4materials reveals Na+ions only partially intercalated in NiCo2O4and the conversion reaction limited by the strain. Next, NiCo2O4nanosheets on Ni foam as a binder-free anode for LIBs are investigated which suggest the positive effect of 3D nanostructures on the morphology stability. As a result, NiCo2O4nanosheets deliver a high lithiation capacity of 1092 mAh g− 1after 100 cycles at 0.5 A g− 1and an excellent rate capacity of 643 mAh g− 1at 4 A g− 1. Finally, NiCo2O4nanospheres are evaluted as a SIB anode which indicate the smaller particle size of active materials is beneficial to the release of stress and structure stability during discharge-charge processes. A rational design of the electrode’ architecture is very important for the conversion-type 3d transition metal oxide anodes for advanced LIBs and SIBs.

Abstract
Background Ticks and tick-borne diseases (TTBDs) are a significant threat to livestock production in sub-Saharan Africa. Transhumance pastoralism practiced in Karamoja region and other factors like cattle trade, communal grazing and the presence of wildlife predispose cattle to TTBDs. Tick species abundance and distribution data can be used as a tool for early disease diagnosis and inform tick control strategies. However, these data for north-eastern Uganda are currently limited; previous surveys were relatively localized and targeted fewer cattle kraals and numbers.Methods We randomly collected tick specimens from 1,534 cattle spread across Karamoja region in both the peak month of the rainy (May) and the dry (February) seasons. The ticks were identified using morpho-taxonomic keys and the tick species identities confirmed by the 16S rRNA gene sequencing and phylogenetic analysis.Results A collection of 18,637 ticks was examined and 15 tick species from three genera (10 Rhipicephalus; 3 Amblyomma; 2 Hyaloma species) were identified. Rhipicephalus appendiculatus was the most dominant (37.9%) tick specie, followed by Amblyomma variegatum (32.3%); A. lepidum (17.3%); R. evertsi evertsi (7.8%); and R. decoloratus (1.4%). Eight of these tick species were ubiquitous in the study districts while six were found in isolated areas. The peak month of the dry season collection was associated with a higher proportion of tick-infested cattle (91%) compared to the peak month of the rainy season (89.8%); a difference that we did not find statistically significant (χ2 = 0.5077, n = 1385, p = 0.476). The overall cattle infestation rate was mainly dominated by 5 tick species namely: A. variegatum (55%), R. appendiculatus (53%), A. lepidum (41%), R. Evertsi (22%), and R. Decoloratus (8%). Napak and Amudat districts registered the highest (95.4% and 94.9%) and lowest (80.9% and 80.7%) cattle tick infestation rates during the peak months of the rainy and dry seasons respectively. Rhipicephalus microplus was confirmed in Amudat, Kaabong and Napak districts.Conclusion This study demonstrates high cattle tick infestation rates by a battery of tick species in Karamoja region. We identified both R. microplus and R. decoloratus which indicates that R. microplus has recently been introduced in this region. This calls for effective tick control responses to prevent further spread of this invasive cattle tick specie.

Published: April 2023

Abstract
A study was conducted to evaluate dietary valine (Val) requirement for Pacific white shrimp (Litopenaeus vannamei). Five isonitrogenous (353 g/kg) and isocaloric (4.08 kcal/g) semi-purified diets containing graded levels of Val (3, 6, 9, 12 or 15 g/kg) were formulated. Quadruplicate groups of 12 shrimp (average body weight: 0.46 ± 0.00 g) were fed one of the experimental diets (2–5% of total body weight) for 11 weeks. Maximum weight gain was observed in 9 g/kg Val group. However, the growth performance was reduced when Val concentration in diets were higher than 12 g/kg. Shrimp fed the diets containing 3 g/kg Val showed significantly lower protein efficiency ratio, whole-body crude protein and Val concentrations. Dietary inclusion of Val significantly improved the relative expression of insulin-like growth factor binding protein and immune-related genes (prophenoloxidase, lysozyme and crustin) in the hepatopancreas and 9 g/kg Val group showed highest expression among all the groups. Polynomial regression analysis revealed that diet for juvenile L. vannamei requires to contain approximately 9.5 g/kg of Val (27 g/kg based on protein level) to ensure optimal growth and improving overall health.

Published: April 2023

Abstract
Objectives The study aims to determine the level of awareness, knowledge, and practice patterns of Oral Health and Hygiene (OHH) among Speech-Language Pathologists (SLPs) in India.Materials & Method A questionnaire was developed to assess the awareness and knowledge regarding OHH among Master's students and professionals practicing speech-language pathology. The sections in the questionnaire included awareness and knowledge of oral health, knowledge of impact of poor oral health, and practices pertaining to assessment and management of oral health. The questionnaire was circulated among 200 SLPs practicing in India.Results A total of 162 participants responded to the survey. 93.2% participants were aware of the importance of OHH, however 42.6% participants did not feel confident enough to assess the same. Most (82.7%) agreed that poor OHH could lead to different health complications. 38.8% of the participants responded that they assessed oral health only sometimes and 54.3% reported that they never used standard screening/assessment tools to assess oral health. Only a very small percentage of participants (28.65%) counselled the patients for maintenance of oral hygiene and more than 40% never recommended appropriate OHH practices during management.Conclusion The present study is the first of its kind to assess the awareness, knowledge, and practice patterns of OHH among Indian SLPs. The results revealed that though the awareness and knowledge of OHH among the Indian SLPs was good, this did not reflect in their clinical practiceClinical Relevance: Collaborative efforts from professional and regulatory bodies and educational institutes are necessary in developing and implementing OHH-related aspects in India. This could potentially improve SLP's knowledge and clinical practices related to oral health and thereby improve patient outcomes.

Published: April 2023

Abstract
Background Hydroxyurea (HU), a fetal hemoglobin inducer is effective in alleviating the symptoms of beta-thalassemia patients; however, its efficacy is not the same in all patients. Hydroxyurea metabolism in the gut might be responsible, which, as several studies suggest, impacts the metabolism of drugs and diseases including sickle cell diseasea and thalassemia. Hydroxyurea also influences the composition of the gut microbiota as evidenced by literature. In this study, we attempted to find a relationship between the gut microbiota and the response difference of hydroxyurea in beta-thalassemia major patients.Methods A total of 45 Beta-thalasssemia patients stool samples were collected. They were divided into 3 groups; responders, non-responders, and non-users of hydroxyurea. The samples of each group were pooled into 6 samples after DNA extraction. The V3-V4 hyper-variable region of the 16SrRNA gene was sequenced.Results The three groups did not differ in alpha diversity. Our study revealed significant differences in the gut microbiota of hydroxyurea responders, non-responders and non-users at genus and species level. Hydroxyurea response was found to be associated with butyrate producers belonging to phlyum Firmicutes. The responders were enriched in genera belonging to phylum Firmicutes especially Butyrate-producing bacteria such as Faecalibacterium, Butyrivibrio, Oscillobacter, Gemmiger, and Eubacterium. The non-responders were abundant in Prevotella, Mitsuokella, and Treponema. The non-users were abundant in Succinivibrio, followed by Bacteroides, and Megasphaera.Conclusion Our results suggest that the altered gut microbiota might be the reason for inter-individual variation of hydroxyurea and reveals various microbes that may serve as potential biomarkers for thalassemia or hydroxyurea efficacy.

Abstract
With the Rapid urban expansion and development, the contradiction between human and land has gradually emerged, and how to scientifically and rationally use land is an inescapable problem. Nanchang was selected to study in the study, land use change images of Landsat from 2005 to 2020 was analyzed, and predicted land use situation of Nanchang in 2035 by CA-Markov model, to analyze and evaluate the scientific and effective use of land resources in Nanchang. The results show that from 2005 to 2020, woodland continued to decrease, with a total decrease of 300.27 km2 in 15 years; unused land was developed into construction land and agricultural land, the proportion of unused land became less and less; the proportion of grassland and construction land increased, and the expansion rate of construction land increased. Agricultural land, woodland, grassland and water area are greatly affected by elevation slope; The construction land is greatly affected by the convenience of transportation, and the old construction land as the initial boundary of expansion has driven the transformation of surrounding land use. In 2035, agricultural land will remain largely stable; wood land will slightly decrease; both grassland and water area show a decreasing trend; the construction land increase by 306.31km2. Understanding the characteristics and laws of land use change in Nanchang is conducive to urban sustainable development planning. Simultaneous development and protection are conducive to the sustainable use of land resources and sustainable regional development.

Published: April 2023

Abstract
Background
To investigate the expression of EBV products and incidence of Gallstone disease (GD) among different microsatellite status in colorectal cancer (CRC) with BRAFV600E mutation.
Methods
We collected 30 CRC patients with BRAFV600E mutation and 10 BRAF (-) CRC patients as well as 54 healthy subjects. Tumor tissue samples were collected to detect the mutation of BRAF, KRAS, and TP53. Microsatellite status was determined by immunohistochemistry and PCR. EBER in situ hybridization was performed to detect EBV. In addition, we also collected clinical information about the patients.
Results
We found that although EBV products were detected in CRC, there were no significant differences in the EBV distribution between the different BRAF groups. Our study demonstrated that BRAFV600E mutation and BRAFV600E with MSI were significantly more frequent in the right CRC. Furthermore, the KRAS mutation rate in the BRAF-wild type group was proved to be significantly higher than that in the BRAF mutation group. In addition, we revealed that BRAF mutation and MSI were independent risk factors of TNM stage. The incidence of GD was higher in CRC patients than in general population, and although there was no significant difference between CRC with or without BRAFV600E mutation, the highest incidence of GD was found in MSS CRC with BRAFV600E mutation.
Conclusions
EBV plays a role in CRC, but is not a determinant of different microsatellite status in CRC with BRAFV600E mutation. The incidence of GD in MSS CRC with BRAFV600E mutation is significantly higher than that in the general population.

Authors: Wu Jingjing , Huang Miao , Huang Zhijun , Yuan Hong 
Published: April 2023

Abstract
Background
Previous studies have demonstrated the adverse effect of single metal on blood pressure (BP) by oxidative stress, however, few studies investigated the joint effect of multi-metals co-exposure on BP. We aimed to estimate the association between multi-metal co-exposure and BP.
Methods
2,764 residents living in heavy metal-contaminated areas of China for at least 5 years were recruited from August 2016 to July 2017 in this study. The average concentration of plasma zinc (Zn) and lead (Pb) and urine arsenic (As) and cadmium (Cd) were measured using an inductively coupled plasma mass spectrometer. The Ordinary least squares (OLS) linear regression and Bayesian kernel machine regression (BKMR) were utilized to assess the effect of the metals on systolic blood pressure (SBP) and diastolic blood pressure (DBP). All the metals were naturally log-transformed and As and Cd in urine were adjusted for urine creatinine levels.
Results
A total of 1,859 participants (58.40 ± 13.42 years old, 40.02% men) were included in the final analysis. The OLSlinear analyses showed that Zn and As were positively associated with SBP and DBP, while Cd was negatively associated with SBP and DBP. In the BKMR, we found a significantly positive joint effect of the metal mixture on BP when all the metal concentrations were above their medians. We also found the effects of the interaction between As and Zn on BP.
Conclusions
In conclusion, our study showed that multi-metal co-exposures caused an increase in BP in the population. Further prospective studies with larger sample sizes are necessary to validate this finding.

Published: April 2023

Abstract
To address the problem of survival of macroalgal zygote transplants, six adhesives were mixed with Sargassaceae zygotes and incubated to determine their adhesion and germination. The adhesives with the highest zygote survival were selected, and then 4% alginate and 3% CaCl2 were mixed with the zygotes and applied to three adhesion substrates with different levels of roughness. The zygote attachment density was used to determine the combination of adhesives and substrates that was most favorable for zygote adhesion. The results showed that: (1) The zygote attachment density of coated alginate reached 259 ind. cm− 2, with a survival rate of 9.4. Although the attachment density of zygotes encapsulated with hyperbranched polymeric adhesive (HBPA) was low, the material was viscous, adhesive, and slow to dissolve, giving it potential as an outdoor transplant adhesion material. (2) The attachment density of zygotes on brick, cement board, and PVC substrates sprayed with 3% CaCl2 reached 86 ind. cm− 2, 48 ind. cm− 2, and 8 ind. cm− 2, and the survival rate was 52%, 29%, and 5%, respectively. The rougher the substrate, the more zygotes adhered. Therefore, in macroalgae restoration and seaweed farm reconstruction, artificial algal reefs with a rough substrate and granular dents could be used in combination with the application of adhesives. The results of this study will help to address the environmental constraints affecting the artificial transplantation of macroalgae and aid in the development of innovative habitat restoration techniques for macroalgae habitats.

Abstract
Laboratory surveillance of Streptococcus pneumoniae serotypes is crucial for the successful implementation of vaccines to prevent invasive pneumococcal diseases. The reference method of serotyping is the Quellung reaction, which is labor-intensive and expensive.
In the last few years, the introduction of MALDI-TOF MS into the microbiology laboratory has been revolutionary. In brief, this new technology compares protein profiles by generating spectra based on the m/z ratio.
We evaluated the performance of MALDI-TOF MS for typing serotypes of S. pneumoniae isolates included in the PCV13 vaccine using a machine learning approach. We challenged our classification algorithms with a total of new 215 isolates of S. pneumoniaefrom Argentinian nationwide surveillance.
Our work involved a thorough evaluation and comparison of multiple machine learning models. Through this evaluation, we achieved high accuracy values, indicating the effectiveness of the approach taken in solving the problem. Additionally, we attained high kappa index values, indicating that the predictions made by the models were highly accurate and reliable. We also carefully considered the strengths and limitations of each model. As such, our results are highly valuable and have important implications for future research and applications.
On a cross-diffusive SIS epidemic model with power-like nonlinear incidence
Authors: Li Huicong , Xiang Tian 
Published: April 2023

Abstract
Note: Please see pdf for full abstract with equations.
We study global existence, boundedness and convergence of non-negative classical solutions to a Neumann initial-boundary value problem for the following possibly cross-diffusive SIS (susceptible-infected-susceptible) epidemic model with power-like infection mechanism generalizing the standard mass action incidence:
St = dS∆S + χ∇ · (S∇I) − βSqIp + γI, x ∈ Ω, t > 0,
It = dI∆I + βSqIp − (γ + µ)I, x ∈ Ω, t > 0,
in a bounded smooth domain Ω ⊂ Rn (n ≥ 1). The infection force of the form βSqIp with p, q > 0 is a natural extension of the classical mass action type βSI, and the cross-diffusive term χ∇ · (S∇I) with χ ≥ 0 describes the effect that the susceptible individuals tend to move away from higher concentration of infected populations. Global existence and boundedness of classical solutions are established in certain parameter ranges, and threshold/non-threshold long-time behaviors of global bounded solutions are also detected. Our findings significantly improve and extend previous related studies.
