Published: January 2023

Abstract
The concept of the “Anthropocene” was first proposed in the early 21st century and aroused widespread discussion in the public and geological community; however it still requires formal definition. The Global Boundary Stratotype Section and Point (GSSP) is a key tool in this process. Accurate chronology and high-resolution samples are the material basis for studying the Anthropocene. The varved sediment, deposited in Sihailongwan Maar Lake (42°17′N, 126°36′E) in northeast China, is a GSSP candidate site and a new location for studying the Anthropocene as a new stratigraphic unit. Anthropocene strata are the top few centimeters of sediment and characterized by small thickness, high water content, and lack of compaction and consolidation, which is physically different from older strata and requires special sampling and processing methods. There is currently a lack of standard and normative sampling and sample processing methods. Therefore, we propose a new paradigm specifically for the precise study of the top 20 cm of loose sediments. To avoid disturbing and disrupting the deposition sequence and structure of the sediments, freezing techniques and cryogenics were applied in coring and core processing. A freeze corer was used to collect the varved sediments in situ. To eliminate the effect of high water-content on X-ray fluorescence core scanning, core strips were freeze-dried and impregnated with resin prior to scanning. By cross-varve dating between parallel cores, we established a precise chronology with an annual resolution, and the age uncertainty was nearly eliminated. The top 20-cm long core represents approximately the last 210 years of deposition. At present, the early 1950s is recommended as the onset of the Anthropocene, the corresponding depth in 1950 CE was between 85-95 cm in our parallel cores. To obtain samples with high temporal resolution for proxy analyses, the cores were subsampled along the varve direction at 1 or 2 mm intervals with a scalpel knife in a -10 °C room, which represents an average of ~2 years. For loose Anthropocene sediments, freeze coring, freeze subsampling, and cross-dating are key for ensuring research accuracy.

Published: January 2023

Abstract
We investigate a pattern of isotopes with the highest isotopic abundance, the number of nucleons
of some stable nuclides tends to A=S(S+1)-2, this means that S is probably the number of shells.
Therefore, we present an arrangement pattern of the magic numbers. Further, based on some simple
patterns in atomic nuclei, such as shell structures, magic numbers, magnetic moment and collective
modes, we developed a helical toroidal wave orbital model to explore the microstructure of isotopes
that matches the proposed arrangement pattern.

Abstract
Escherichia Phage CMSTMSU isolated from the semi-intensive shrimp farm was efficient lytic activity and strong host range against Escherichia coli. A High Density Polyethylene (HDPE) template was used to inhibit biofilm activity against E. coli, and results obtained using a confocal laser scanning microscope showed that the phage efficiently prevented biofilm formation. In order to assess the structural morphology, Escherichia Phage CMSTMSU was investigated using a transmission electron microscope at 80 kV and a magnification of X 12,000. The result revealed that, head measuring about 220–230 nanometer with a hexagonal shape and a non-contractile tail and the phage belongs to Siphoviridae family. By using a spectrophotometric assay to measure the killing efficiency, it was found that the phage significantly (P < = 0.001) contributed to a reduction in E. coli cell densities over time. Escherichia phage CMSTMSU's stability was tested at various temperatures and pH levels, and the results showed that the phage was stable at temperatures of 40 and 50˚C and pH levels of 5 to 9, respectively. These results were considerably (P < = 0.001) different from those of other temperatures and pH levels. The one-step growth curve showed a positive correlation, which indicated that the burst size grew considerably (P < 0.05) as the time increased.

Published: January 2023

Abstract

Archaeological iron artifacts are often covered with a crust, containing organic fibers, mineral particles, dirt, etc. Before conservation, this crust must be carefully removed. With traditional mechanical and chemical methods, there is an obvious risk of over-cleaning. These methods also increase the risk of the oxidized or primary corrosion layer breaking away which will lead to loss of information about the form of the object and other important surface details. The same archaeological iron spears from Military Museum, Al-Qala, Egypt were selected for the study. The aim of this case study is concerned with preserving and controlling the corrosion of steel spears heads. Due to the restriction of the archeological parts preservation and corrosion control are achieved by environmentally friendly chemicals. This inhibitor is of attentiveness since there has been a growth in ecological consciousness and a variation in guidelines that control the toxicity of systematic corrosion inhibitors. So, natural products are becoming the main source of environmentally friendly corrosion inhibitors. Furthermost their extracts comprise the required features of the traditional corrosion inhibitors such as oxygen, carbon, nitrogen, and sulfur. These elements are contributed to the adsorption process on the metal surfaces and arrangement a protective layer, which shields the metal surface against environmental corrosion. Progress of green chemical knowledge compromises a new artificial approach for ionic liquids. These compounds are well-thought-out as new safe corrosion inhibitors which act in different corrosive conditions. Finally, exploiting the successfully obtained results, we used this inhibitor to protect the selected objects.

Published: January 2023

Abstract
Understanding the complex biomechanical tumor microenvironment (TME) is of critical importance in developing the next generation of anti-cancer treatment strategies. This is especially true in epithelial ovarian cancer (EOC), the deadliest of the gynecologic cancers due to recurrent disease or chemoresistance. However, current models of EOC progression provide little control or ability to monitor how changes in biomechanical parameters alter EOC cell behaviors. In this study, we present a microfluidic device designed to permit biomechanical investigations of the ovarian TME. Using this microtissue system, we describe how biomechanical stimulation in the form of tensile strains upregulate phosphorylation of HSP27, a heat shock protein implicated in ovarian cancer chemoresistance. Furthermore, EOC cells treated with strain demonstrate decrease response to paclitaxel in the in vitro vascularized TME model. The results provide a direct link to biomechanical regulation of HSP27 as a mediator of EOC chemoresistance, possibly explaining the failure of such therapies in some patients. The work presented here lays a foundation to elucidating mechanobiological regulation of EOC progression, including chemoresistance and could provide novel targets for anti-cancer therapeutics.

Authors: Gorji Faezeh Faghihzade , Sadr Soheil , Borji Hassan 
Published: January 2023

Abstract
Background

We conducted a cross-sectional study of indigenous breeds of horses from the north and northeast of Iran to establish the prevalence and distribution of Eimeria species.

Material and Methods

340 fecal samples from randomly selected horses (141 from the north of Iran and 199 from the northeast of Iran) were examined for Eimeria oocyst using standard coprological techniques.

Results

Out of 340 samples, only 3 from north Iran were positive for coccidiosis. Two infections occurred by E. leuckarti species, and one infection happened by E. uninugulata. The mean intensity of oocyst output (3–38 o.p.g.) was very low. No clinical signs of gastrointestinal disorder were noticed in any horses during this study.

Conclusion

This study reports for the first time on the prevalence of E. uninugulata in horses from farms in North Iran. A more comprehensive study in different rural areas of Iran would be advantageous to develop a better understanding of the molecular identification and characterization of Eimeria species and strengthen the knowledge we currently have.
Management of dental care of patients on immunosuppressive drugs for chronic immune-related inflammatory diseases: a survey of French dentists' practices

Published: January 2023

Abstract
Objectives
Our aim was to provide an overview of the practices of French general dentists (GDs) and specialists (SDs) concerning the management of patients with inflammatory bowel diseases (IBDs), rheumatic inflammatory diseases (IRDs), and vasculitis on biologic disease-modifying antirheumatic drugs (bDMARDs), conventional DMARDs, or immunosuppressants (ISs).
Materials and Methods
We asked the members of French scientific societies and colleges of dentistry teachers to distribute an online survey over three months.
Result
In total, 105 practitioners fully completed the survey. SDs more frequently performed invasive surgical procedures and were more aware of the recommendations of learned societies than GDs. They encountered more post-operative complications for patients on bDMARDs. For both SDs and GDs, most patients were managed without stopping treatment and pre- and postoperative antibiotics were prescribed to more than 75% of patients. When medical treatment was stopped, the decision was made by the prescribing physician.
Conclusion
Complications were reported more frequently by SDs when highly invasive procedures were performed on patients under active drug therapy. Certain common procedures, such as scaling and root planing, appear to be safe, regardless of treatment management. However, adapted guidelines for the practice of dentistry are needed to standardize the management of patients on bDMARDS, conventional DMARDs, or ISs.
Clinical Relevance:
French dentists perform a wide range of oral procedures on patients on bDMARDS, conventional DMARDs, or ISs under antibiotic coverage and antiseptic mouthwashes. SDs reported more postoperative complications after extensive invasive procedures for patients under active drug therapy, despite their greater knowledge of recommendations on how to manage such patients.

Abstract
Several studies in psychology suggest that relationships exist between emotional context and motor control. Such a claim is based mainly on behavioral investigations whereas the underlying neurophysiological processes remain little known. Using a classical paradigm in motor control, we tested the impacts of viewing standardized affective pictures during pointing movements performed from a standing position. The hand reaction and movement times were measured and ten muscle activities spread around the body were recorded to investigate the intermuscular coherence between muscle pairs of interest. The hand movement time increased when an emotional picture perceived as unpleasant appeared under the target to reach, compared to an emotional picture perceived as pleasant. When an unpleasant emotional picture appeared, the beta (β, 15-35 Hz) and gamma (γ, 35-60 Hz) intermuscular coherence decreased in the recorded pairs of postural muscles during the initiation of pointing movements. Moreover, a linear relationship between the magnitude of the intermuscular coherence in the pairs of posturo-focal muscles and the hand movement time appeared in the unpleasant scenarios. Our findings demonstrate that emotional stimuli induce modulation of the motor command sent by the central nervous system to muscles when performing voluntary goal-oriented movements.
High-order harmonic generation, attosecond pulse train, and non- sequential double ionization in the helium atom under high-intensity femtosecond laser pulses
Authors: Zakavi Marjan , Sabaeian Mohammad 
Published: January 2023

Abstract
High-order harmonic generation (HHG), attosecond pulse train (APT), and non-sequential double ionization (NSDI) in the He atom under high intense femtosecond laser pulses are calculated by time-dependent Schrodinger equation (TDSE) in one dimension (1D). By considering the mutual electron-electron and electron-nuclei interactions along with calculating the He atom ground state wave function by imaginary time propagation (ITP) method, besides calculating probability density of electrons, dipole acceleration, HHG, and APT, we could generate the well-known "knee structure" in the probability of the He atom ionization against the intensity in an ionization boundary condition model. The results are in good agreement with the experimental data reported by Walker et al. [B. Walker et al. Phys. Rev. Lett. 73, 1227 (1994)].

Authors: Maraqa Beesan , Nazzal Zaher , Baroud Hassan , Douden Mahmoud , Hamshary Yousef El , Jalamneh Tala 
Published: January 2023

Abstract
Background: The emergence of several SARS-CoV-2 variants may necessitate an annual COVID-19 booster vaccine. This study aimed to evaluate healthcare workers' (HCWs) acceptance of a COVID-19 yearly booster vaccine, if recommended, and its association with their attitudes and burnout levels.
Methods: We used an online self-administered questionnaire to conduct a cross-sectional study of all HCWs in the West Bank and Gaza Strip of Palestine between August and September 2022. We used the Vaccination Attitudes Examination scale to assess HCWs' vaccination attitudes and the Maslach Burnout Inventory to assess work-related Burnout. In addition, we conducted logistic regression to identify factors independently associated with the acceptance of the booster vaccine.
Results: The study included 919 HCWs; 52.3% were male, 46.5% were physicians, 30.0% were nurses, and 63.1% worked in hospitals. One-third of HCWs (95% CI: 30.5%-36.7%) said they would accept an annual COVID-19 booster vaccine if recommended. HCWs who are suspicious of vaccine benefits [aOR= .70; 95%CI: .65-.75] and those concerned about unforeseeable future effects [aOR= .90; 95%CI: .84-.95] are less likely to accept the booster vaccine if recommended, whereas those who receive annual influenza vaccine are more likely to get it [aOR= 2.9; 95%CI: 1.7-5.0].
Conclusion: We found that only about a third of HCWs would agree to receive an annual COVID-19 booster vaccine if it was recommended. Mistrust of the vaccine's efficacy and concerns about side effects continue to drive COVID-19 vaccine reluctance. Health officials need to address HCWs' concerns to increase their acceptance of the annual vaccine if it is to be recommended.

Abstract
Present study was designed to quantify the dietary potassium (K) requirement of mori, Cirrhinus mrigala (initial body weight: 5.71 ± 0.02 g) juveniles. Seven isocaloric and isonitrogenous practical diets were formulated by supplementing the graded levels of K at 0, 2, 4, 6, 8, 10 and 12 g/kg, whereas the actual K level was calculated as 2.96, 5.08, 7.03, 9.07, 11.01, 13.13, and 15.09 g/kg, respectively. The feeding trial was carried out in triplicates for 60 days and fish was fed twice a day to apparent satiation. Weight gain%, specific growth rate, feed conversion ratio and organ indices were found to be best (P<0.05) in the fish fed with 9.07 g/kg dietary K supplementation. Gill Na+/K+ ATPase activity also peaked at 9.07 g/kg K. Similarly, deposition of potassium in whole-body, scales and vertebrae significantly (P<0.05) increased with the increase in dietary K supplementation up to 9.07 g/kg. The activities of liver catalase, peroxidase, superoxide dismutase and alkaline phosphatase increased (P<0.05) with an increase in K supplementation from 2.96 to 9.07 g/kg; however, further increase in K supplementation did not necessarily improve these parameters. Contrarily, thiobarbituric acid reactive substances level was observed highest (P<0.05) in fish fed with a basal diet. The data of WG% and gill Na+/K+ ATPase activity were subjected to broken-line regression analysis, and the optimal value of K was estimated to be 7.13 g/kg and 7.87 g/kg, respectively. Therefore, the inclusion of 7.13-7.87 g/kg of K is recommended in the feed of Cirrhinus mrigala juveniles.

Abstract
Background: Reducing Salmonella infection in broiler chickens by using effective and safe alternatives to antibiotics is vital to provide safer poultry meat and minimize the emergence of drug-resistant Salmonella and the spread of salmonellosis to humans. This study was to first evaluate the protective efficacy of feeding a novel coated essential oils and organic acids mixtures (EOA) on broiler chickens infected with Salmonella Enteritidis (S. Enteritidis, SE), and then its action mechanism was further explored.
Methods: 480 1-day-old Arbor Acres male chickens were randomly assigned into five treatments with six replicates, including non-challenged control fed with basal diet (A), SE-challenged control (B), and SE-infected birds fed a basal diet with three levels of EOA (300mg/kg, 500mg/kg and 800mg/kg) (BL, BM and BH), respectively. All birds on challenged groups were infected with SalmonellaEnteritidis at 13 days of age.
Results: Feeding EOA showed a reversed ability on negative effects caused by S. Enteritidis infection, as evidenced by decreasing the feed conversion rate (FCR) and the ratio of villus height to crypt depth (VH/CD) (P < 0.05), obviously decreasing intestinal and internal organs Salmonellaload along with increasing cecal butyric acid-producing bacteria abundance (P < 0.05). Moreover, supplemental different levels of EOA notably up-regulated Claudin-1, Occludin, zonula occludens-1 (ZO-1), mucin-2 (MUC-2), fatty acid binding protein-2 (FABP-2), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), myeloid differential protein-88 (MyD88) and interleukin-6 (IL-6) mRNA levels, whereas down-regulated toll-like receptor-4 (TLR-4) mRNA levels in the ileum of the infected chickens (P < 0.05). Linear discriminant analysis combined effect size measurements analysis (LEfSe) showed that the relative abundance of g__Butyricicoccus, g__Anaerotruncus and g__unclassified_f__Bacillaceaesignificantly was enriched in infected birds given EOA. Also, phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) analysis showed that alpha-linolenic acid metabolism, fatty acid metabolism and biosynthesis of unsaturated fatty acids were significantly enriched in the EOA group.
Conclusion: Our data suggest that the novel essential oils and organic acids mixturescan be used as an antibiotic substitute to control Salmonella Enteritidis infection in broiler chickens.

Published: January 2023

Abstract
Background
Recent studies indicate an increase in the prevalence of overweight and obesity among women in Uganda; these have been associated with factors like age, marital status, income status, the number of children, and level of education, among others. However, most studies rely solely on the body mass index as the indicator of obesity. This study examined the socio demographic factors associated with obesity among women aged 18–59 years in Mukono Central Division of Central Uganda.
Methods
A cross sectional study design using quantitative methods was employed. A total of 384 women between 18 and 59 years were selected by simple random sampling. A semi structured questionnaire and anthropometric measurements were used to collect data.
Results
Age and marital status were positively associated with overweight-body mass index classification (Age–OR 1.9; CI 1.3–3.0; p = 0.003: marital status–OR 2.1; 1.1–3.8; p = 0.021), obese-body mass index classification (Age–OR 2.3; CI 1.3–3.8; p = 0.002: marital status–OR 2.8; 1.1–7.2; p = 0.029), increased risk-waist circumference classification (Age–OR 3.2; CI 2.0–5.1; p = 0.000: marital status–OR 2.4; 1.3–4.6; p = 0.005) and substantially increased risk-waist hip ratio classification (Age–OR 1.9; CI 1.2–3.0; p = 0.005: marital status–OR 2.7; 1.3–5.5; p = 0.006). Age was also positively associated with overfat-Total Body Fat percentage classification(Age–OR 2.2; CI 1.4–3.5; p = 0.001) and excessive-Abdominal Fat Level classification (Age–OR 3.2; CI 1.1–9.4; p = 0.03). Employment status was negatively associated with obese-Total Body fat Percentage classification (Employment status–OR 0.6; CI 0.4–0.9; p = 0.015).
Conclusions
Generalized and abdominal obesity in women were both predicted by age, marital status, and employment status. Identifying the changes that occur in the lives of women as they grow older, get married, and have children, and what it is about being unemployed, that predisposes women to obesity within the Ugandan context, will be instrumental in guiding interventions to curb the emerging obesity epidemic among women in Uganda.
