Molecular imprinting technology (MIT) has been considered as an attractive method to produce artificial receptors with the memory of size, shape and functional groups of the templates and has become an emerging technique with the potential in various fields due to recognitive specificity, high efficient selectivity and mechanical stability, which can effectively remove background interference and is suitable for the pre-treatment and analysis of trace level substances in complex matrix samples. Nearly 100 papers about the application of MIT in the detection of marine pollutants were found through Science Citation Index Expanded (SCIE). On this basis, combined with the application of MIT in other fields, the pre-treatment process of marine environmental samples was summarized and the potential of four types of different molecularly imprinted materials in the pre-treatment and detection of marine organic pollutants (including antibiotics, triazines, organic dyes, hormones and shellfish toxins) samples was evaluated, which provides the innovative configurations and progressive applications for the analysis of marine samples, and also highlights future trends and perspectives in the emerging research field.Erosion of coral substrate plays a crucial role in reef calcium carbonate budget, but little is known about erosion in subtropical corals. In a 2-year study of coral substrate erosion, we deployed Porites skeletal blocks at nine sites across subtropical Hong Kong waters. External erosion varied from 0.05 to 3.07 kg m-2 yr-1 and accounted for 23.4-99.2% of the total erosion. More than half of the study sites had substantial external erosion (> 1 kg m-2 yr-1), and the values were positively correlated with density of the sea urchin Diadema setosum. Excluding urchins from access to the skeletal blocks using cages reduced external erosion by more than 90%. Overall, our study revealed that external erosion caused by urchin grazing contributed predominantly to the total coral skeletal loss in Hong Kong waters. Control of sea urchin population is needed to reduce coral erosion in places with high urchin density. (149 words).
The COVID-19 pandemic represents a public health, economic and mental health crisis. We hypothesized that timely government implementation of stringent measures to reduce viral transmission would benefit mental health, as evidenced by reduced rates of depressive symptoms (i.e., Patient Health Questionnaire [PHQ]-9≥10, PHQ-2≥3).

The systematic review herein (PROSPERO CRD42020200647) evaluated to what extent differences in government-imposed stringency and timeliness of response to COVID-19 moderate the prevalence of depressive symptoms across 33 countries (k=114, N=640,037). We included data from six lower-middle-income countries, nine upper-middle-income countries, and 18 higher-income countries. Government-imposed stringency and timeliness in response were operationalized using the Oxford COVID-19 Government Response ("Stringency") Index.

The overall proportion of study participants with clinically significant depressive symptoms was 21.39% (95% CI 19.37-23.47). The prevalence of clinically significant depressive symptoms was significantly lower in countries wherein governments implemented stringent policies promptly. The moderating effect of government response remained significant after including the national frequency of COVID cases at the time of study commencement, Healthcare Access and Quality index, and the inclusion of COVID patients in the study.

Factors that may have confounded our results include, for example, differences in lockdown duration, lack of study participant and outcome assessor blinding, and retrospective assessment of depressive symptom severity.

Governments that enacted stringent measures to contain the spread of COVID-19 benefited not only the physical, but also the mental health of their population.

Iron (Fe) is one of the most essential trace elements in the body that play crucial role in organisms' survival, however, excess deposition of it puts patients at higher risk of iron overload and tissue injury through production of reactive oxygen species (ROS), elevation of oxidative stress, development of endocrine disorders among which hypogonadism, and increased incidence of cells damage in vital organs. As deferasirox (DFX) is an approved Fe chelator drug, its inability to cross blood brain barrier (BBB) remains a definite obstacle against its use as Fe chelator in the brain. Lately, attention to nanoparticles usage in researches has been widely grown since their role in improving drug therapeutic effects and scavenging free radicals make them good candidates as chelating and antioxidant agents.

Herein, after induction of iron overload, organo-modified casein immobilized silver nanocomposite (Ag@Tr-CA) was designed and explored as combined therapy with DFX drug to develop its penetrating efficiency t that combination of Ag@Tr-CA nanocomposite with DFX makes it a promising co-treating agent against iron overload through improving the physiological, molecular, and histological structure of the brain in iron overloaded rats.
The present results showed that combination of Ag@Tr-CA nanocomposite with DFX makes it a promising co-treating agent against iron overload through improving the physiological, molecular, and histological structure of the brain in iron overloaded rats.The surface-enhanced Raman scattering (SERS) has been widely tested for its usefulness in microbiological studies, providing many information-rich spectra which are a kind of 'whole-organism fingerprint' and enabling identification of bacterial species. Here we show, previously not considered, the comprehensive SERS-chemometric analysis of five bacterial pathogens, namely Neisseria gonorrhoeae, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Haemophilus ducreyi, all being responsible for sexually transmitted diseases (STDs). https://www.selleckchem.com/products/valemetostat-ds-3201.html In the designed biosensor, the direct, intrinsic format of the spectroscopic analysis was adopted for the SERS-based screening of gonorrhea and chlamydiosis due to vibrational analysis of men's urethra swabs. Our experiments demonstrated that the applied method enables identification the individual species of the Neisseria genus with high accuracy. In order to differentiate the sexually transmitted pathogens and to classify the clinical samples of male urethra swabs, three multivariate methods were used.
