Corona Virus Net is the web resource for anyone interested in Coronaviruses. Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (COVID-19) is a new strain that has not been previously identified in humans. Coronaviruses are zoonotic, meaning they are transmitted between animals and humans. Common signs of infection include respiratory symptoms, fever, cough, and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death. Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing. Also avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
A pneumonia of unknown cause detected in Wuhan, China was first reported to the WHO on 31 December 2019. The outbreak of COVID-19 was declared a Public Health Emergency of International Concern on 30 January 2020 by the WHO. As of March 11th, the WHO declared the rapidly spreading coronavirus outbreak a pandemic, acknowledging that the virus will likely spread to all countries in the world.
The objectives of Corona Virus Net are to be the public and professional information resource for coronaviruses and to serve as a network in the exchange of information and news related to coronaviruses. What do you know about the novel Coronavirus that is causing a health emergency?

Mon, 20 Sep 2021 21:44:10 -0400
COVID-19 -- Worldwide/Unknown
A lower dose of the Pfizer-BioNTech coronavirus vaccine -- one-3rd the amount given to adults and teens -- is safe and triggered a robust immune response in children as young as 5 years old, the drug companies announced in a news release Monday morning.
The finding, eagerly anticipated by many parents and pediatricians, is a crucial step toward the 2-shot coronavirus vaccine regimen becoming available for younger school-aged children, perhaps close to Halloween.

- Toward a Unified Description of the Electrostatic Assembly of Microgels and Nanoparticles Thu, 07 Dec 2023 06:00:00 -0500
The interplay of soft responsive particles, such as microgels, with nanoparticles (NPs) yields highly versatile complexes that show great potential for applications, ranging from plasmonic sensing to catalysis and drug delivery. However, the microgel-NP assembly process has not been investigated so far at the microscopic level, thus hindering the possibility of designing such hybrid systems a priori. In this work, we combine state-of-the-art numerical simulations with experiments to elucidate...
- Influence of pesticide exposure on farmers' cognition: A systematic review Thu, 07 Dec 2023 06:00:00 -0500
CONCLUSION: Despite the limited number of trials, we found scientific evidence to support the existence of adverse effects of pesticides on farmers' cognition. We recommend that future studies research similar projects, expanding knowledge on the subject.
- Hoyaspectatissima (Gentianales, Apocynaceae), a new species from Yunnan, China Thu, 07 Dec 2023 06:00:00 -0500
Hoyaspectatissima, a new species from Yunnan Province, China, is described and illustrated. Hoyaspectatissima is morphologically similar to H.lyi, but can be easily distinguished from the latter by its succulent leaves that are 2‒4.5 cm long (vs. coriaceous leaves that are up to 9 cm long), corolla that is pink to pale pink (vs. yellowish-white) and corona lobes that are sub-rhombic in top view (vs. ovoid in top view).
- Identifying effective factors to alleviate postnatal distress and coronavirus anxiety in mothers of hospitalized preterm neonates Wed, 06 Dec 2023 06:00:00 -0500
CONCLUSIONS: The correlation between CA and PDM suggests that preterm neonate's mothers experienced increased anxiety during the pandemic. Considering the factors influencing these anxieties, targeted programs should be developed to enhance the mental health of these mothers in future pandemics. The finding that women with more children experienced less CA could serve as evidence of the positive impact of having children on the mental health of women with premature infants during a pandemic.
- Study protocol for evaluating the current status and needs assessment of health-related characteristics among students at Albert-Ludwigs-University Freiburg Wed, 06 Dec 2023 06:00:00 -0500
Today, university students face study conditions that increase the risk of sedentary behavior, unhealthy eating, and the likelihood of stress, anxiety, and depression. Although the situation has likely worsened in recent months due to the COVID-19 pandemic, even in the pre-Corona era, several investigations have demonstrated that the students' health behaviors could increase the incidence of metabolic risk factors and non-communicable diseases, however, further and detailed information is needed...
- Unveiling protein corona formation around self-propelled enzyme nanomotors by nanoscopy Wed, 06 Dec 2023 06:00:00 -0500
The interaction of nanoparticles with biological media is a topic of general interest for drug delivery systems and among those for active nanoparticles, also called nanomotors. Herein, we report the use of super resolution microscopy, in particular, stochastic optical reconstruction microscopy (STORM), to characterize the formation of a protein corona around active enzyme-powered nanomotors. First, we characterized the distribution and number of enzymes on nano-sized particles and characterized...

CONCLUSION: Patients with recurrent preterm birth have higher self-reported anxiety using the Generalized Anxiety Disorder 7-item screen than controls. Of those with a positive screen, 17% were diagnosed with a perinatal mood disorder.
- Visualizing the Birth and Monitoring the Life of a Bimetallic Methanation Catalyst Tue, 05 Dec 2023 06:00:00 -0500
Well-defined bimetallic heterogeneous catalysts are not only difficult to synthesize in a controlled manner, but their elemental distributions are also notoriously challenging to define. Knowledge of these distributions is required for both the as-synthesized catalyst and its activated form under reaction conditions, where various types of reconstruction can occur. Success in this endeavor requires observation of the active catalyst via in situ analytical methods. As a step toward this goal, we...
- Enzymatic Synthesis of Aptamer-Polynucleotide Nanoparticles with High Anticancer Drug Loading for Targeted Delivery Tue, 05 Dec 2023 06:00:00 -0500
We report a targeted prodrug delivery platform that can deliver a cytostatic nucleobase analog with high drug loading. We chose fluorouracil (5FU), a drug used to treat various cancers, whose active metabolite 5-fluorodeoxyuridine monophosphate (5-FdUMP) is the antineoplastic agent. We use terminal deoxynucleotidyl transferase (TdT) to polymerize 5-fluorodeoxyuridine triphosphate (5-FdUTP) onto the 3'-end of an aptamer. We find that (i) addition of hydrophobic, unnatural nucleotides at the...
- Cytokine-responsive T- and NK-cells portray SARS-CoV-2 vaccine-responders and infection in multiple myeloma patients Mon, 04 Dec 2023 06:00:00 -0500
Patients with multiple myeloma (MM) routinely receive mRNA-based vaccines to reduce COVID-19-related mortality. However, whether disease- and therapy-related alterations in immune cells and cytokine-responsiveness contribute to the observed heterogeneous vaccination responses is unclear. Thus, we analyzed peripheral blood mononuclear cells from patients with MM during and after SARS-CoV-2 vaccination and breakthrough infection (BTI) using combined whole-transcriptome and surface proteome...
