1. In silico prediction of inhibitory potential of a punicalagin β-anomer against SARS-COV-2 main protease (MPRO)
The pandemic caused by the new coronavirus has resulted in a global health emergency and has prompted an urgent need for new treatment strategies. No target-specific drugs are currently available for SARS-CoV-2, but new drug candidates targeting the viral replication cycle are being explored. A prime target of drug-discovery efforts is the SARS-CoV-2 main pr

2. DNA replication stress: oncogenes in the spotlight
Abstract Precise replication of genetic material is essential to maintain genome stability. DNA replication is a tightly regulated process that ensues faithful copies of DNA molecules to daughter cells during each cell cycle. Perturbation of DNA replication may compromise the transmission of genetic information, leading to DNA damage, mutations, and chromoso

3. Identification of the molecular mechanisms associated with acute type A aortic dissection through bioinformatics methods
Aortic dissection is characterized by the redirection of blood flow, which flows through an intimal tear into the aortic media. The purpose of this study was to find potential acute type A aortic dissection (AAAD)-related genes and molecular mechanisms by bioinformatics. The gene expression profiles of GSE52093 were obtained from Gene Expression Omnibus (GEO

4. Synthetic and minimalist vectors for Agrobacterium tumefaciens-mediated transformation of fungi
Abstract We present a collection of minimalist binary vectors for transformation through ATMT applicable to several fungi species. pLUO plasmid binary vectors consist of a reporter module containing fluorescent proteins, mCherry or eGFP, flanked by a multiple cloning site and a transcription terminator site. They also present a synthetic gene allowing resist

5. Probing the Pharmacological Parameters, Molecular Docking and Quantum Computations of Plant Derived Compounds Exhibiting Strong Inhibitory Potential Against NS5 from Zika Virus
ABSTRACT Zika virus (ZIKV) is known for microcephaly and neurological disease in humans and the nonstructural proteins of ZIKV play a fundamental role in the viral replication. Among the seven nonstructural proteins, NS5 is the most conserved and largest protein. Two major functional domains of NS5 i.e. methyltransferase (MTase) and RNA-dependent RNA polymer

6. Dyslexia risk variant rs600753 is linked with dyslexia-specific differential allelic expression of DYX1C1
Abstract An increasing number of genetic variants involved in dyslexia development were discovered during the last years, yet little is known about the molecular functional mechanisms of these SNPs. In this study we investigated whether dyslexia candidate SNPs have a direct, disease-specific effect on local expression levels of the assumed target gene by usi

7. Docking and QM/MM Studies of NS2B-NS3pro Inhibitors: a Molecular Target against the Dengue Virus
Dengue virus (DENV) has been characterized as having great clinical importance in the world, as there is no specific treatment against this virus. The NS2B-NS3pro complex is essential for the replication and maturation of DENV and is a potential pharmacological target. The present study aims to evaluate and understand the interactions and affinities (via mol

8. Macrophages as target cells for Mayaro virus infection: involvement of reactive oxygen species in the inflammatory response during virus replication
ABSTRACT Alphaviruses among the viruses that cause arthritis, consisting in a public health problem worldwide by causing localized outbreaks, as well as large epidemics in humans. Interestingly, while the Old World alphaviruses are arthritogenic, the New World alphaviruses cause encephalitis. One exception is Mayaro virus (MAYV), which circulates exclusively

9. Efficient assembly of full-length infectious clone of Brazilian IBDV isolate by homologous recombination in yeast
The Infectious Bursal Disease Virus (IBDV) causes immunosuppression in young chickens. Advances in molecular virology and vaccines for IBDV have been achieved by viral reverse genetics (VRG). VRG for IBDV has undergone changes over time, however all strategies used to generate particles of IBDV involves multiple rounds of amplification and need of in vitro l

10. Extraction of DNA from honey and its amplification by PCR for botanical identification
The physiochemical and biological properties of honey are directly associated to its floral origin. Some current commonly used methods for identification of botanical origin of honey involve palynological analysis, chromatographic methods, or direct observation of the bee behavior. However, these methods can be less sensitive and time consuming. DNA-based me

11. Construction and characterisation of a complete reverse genetics system of dengue virus type 3
Dengue virulence and fitness are important factors that determine disease outcome. However, dengue virus (DENV) molecular biology and pathogenesis are not completely elucidated. New insights on those mechanisms have been facilitated by the development of reverse genetic systems in the past decades. Unfortunately, instability of flavivirus genomes cloned in E

12. Modelagem molecular de uma série de compostos inibidores da enzima integrase do vírus HIV-1 / Molecular modelling for a series of integrase HIV-I inhibitors
An essential step in the HIV life cycle is integration of the viral DNA into the host chromosome. This step is catalyzed by a 32-kDa viral enzyme HIV integrase (IN). HIV-1 IN is an important and validated target, and the drugs that selectively inhibit this enzyme, when used in combination with reverse transcriptase (RT) and protease (PR) inhibitors, are beli
