Plastic pollution has become a global threat to the marine environment. Many studies have indicated that marine creatures are at risk of plastic ingestion, but relevant studies are still lacking in Taiwan. In this study, we quantified plastic debris ingestion by marine fish in the coastal waters of the Hengchun Peninsula, including the Kenting National park, located in southern Taiwan. We also investigated possible biotic and abiotic factors associated with the quantity of ingested plastic by fish. HDAC inhibitor In the 117 fish samples we examined, 94.87% of them had ingested plastic debris, and all of the observed debris was microplastics ( less then 5 mm). The average number of ingested microplastics was 5.6 ± 5.1 pieces per fish (ranged 0-32 pieces per fish). The major type and color of microplastics were fiber (96%) and blue (43%), respectively. The quantity of ingested microplastics was not significantly different between the reef and pelagic fish. However, reef fish from the more populated west and south coast ingested more microplastics than that from the east coast, suggesting that microplastic ingestion by fish is related to human activity. Regarding biotic factors, the size, trophic level, and taxonomic family of the fish were not significantly associated with the number of ingested microplastics. Our results, the first investigation of microplastic ingestion in marine fish of Taiwan, show a high prevalence of microplastic ingestion but no biomagnification of microplastics in the fish. More research is much needed to better characterize the biological and ecological impacts of plastic debris on fish.We conducted a large-scale epidemiological investigation to detect the prevalence of Toxoplasma gondii in four marine bivalve shellfish species collected from six representative coastal regions of Weihai, eastern China. Between January 2018 and December 2018, 14,535 marine bivalve shellfish pooled into 2907 samples were randomly collected and examined for T. gondii DNA by a nested PCR assay targeting B1 gene. The results showed that 2.8% (82) of the 2907 pooled samples were tested positive for T. gondii DNA. Two T. gondii genotype (ToxoDB Genotype #9 and ToxoDB Genotype #1) were identified PCR-restriction fragment length polymorphism analysis. Factors that were found significantly associated with the presence of T. gondii DNA in marine bivalve shellfish included the source of samples (being wild) (odds ratio [OR], 3.34; 95% confidence interval [CI], 2.00-5.84; p less then 0.01), surface runoff near the sampling site (OR, 2.64; 95% CI, 1.47-4.72; p less then 0.01), and presence of cats near the sampling site (OR, 1.77; 95% CI, 1.02-3.07; p = 0.04). Moreover, the prevalence of T. gondii DNA in marine bivalve shellfish correlated with temperature (Pearson's correlation R = 0.75, p = 0.0049) and precipitation (R = 0.87, p = 0.00021). These findings provide new insights into the presence of T. gondii DNA in marine bivalve shellfish and highlight the impact of human activity on marine pollution by such an important terrestrial pathogen pollutant.The waste from agriculture can be used for biochar production by the pyrolysis process. The present work aimed was to produce sugarcane bagasse biochars using different temperatures and processes (batch and pilot-scale continuous flow). The samples were characterized by FTIR, functional group pKa, elemental analysis, zeta potential, Raman spectroscopy, EPR, and SEM. The FTIR spectra showed bands around 1400-1650 cm-1 corresponded to vibrations of CC bonds and pKa revealed the presence of carboxylic acids (pKa ≤5) and lactones (pKa ~5-9). The elemental analyses (H/C ~ 0.31) and Raman spectra (ID/IG ~ 0.55) confirmed greater carbonization and less structural disorder of the material produced using the continuous flow process. SEM images showed that the biochar morphologies were similar to that of the precursor biomass, with the formation of pores. The continuous flow process is a promising technique for the production of biochars with high carbon contents and aromatic structures, as well as lower defect degrees, compared to biochars produced using a batch process.Amyloid aggregation and human disease are inextricably linked. Examples include Alzheimer disease, Parkinson disease, and type II diabetes. While seminal advances on the mechanistic understanding of these diseases have been made over the last decades, controlling amyloid fibril formation still represents a challenge, and it is a subject of active research. In this regard, chiral modifications have increasingly been proved to offer a particularly well-suited approach toward accessing to previously unknown aggregation pathways and to provide with novel insights on the biological mechanisms of action of amyloidogenic peptides and proteins. Here, we summarize recent advances on how the use of mirror-image peptides/proteins and d-amino acid incorporations have helped modulate amyloid aggregation, offered new mechanistic tools to study cellular interactions, and allowed us to identify key positions within the peptide/protein sequence that influence amyloid fibril growth and toxicity.
Ebola virus (EBOV); a public health emergency of international concern,is known to pose threat of global outbreaks. EBOV has spread in African continent and due to unchecked international travel, importation of cases has been reported in different countries. In this alarming scenario, developing countries need to evaluate and upgrade their preparedness plan to contain the spread of EBOV. The present review lays down the updated preparedness plan for developing countries to contain future EBOV outbreaks.

The literature on EBOV outbreaks and preparedness strategies reported were searched on Pubmed and Google Scholar using the MeSH terms such as "Ebola virus disease, Epidemic, Outbreak, Imported case, Preparedness, Public health interventions" combined with Boolean operator (OR) for the period of 2011-2020. Additionally, World Health organization (WHO) and Centers for Disease Control & Prevention (CDC) websites were searched for the guidelines, reports, containment strategies, containment plan of countries, actions taken by countries and international partners, etc.
