Cardio- and Neurotoxicity of Selected Anti-COVID-19 Drugs.

Since December 2019, the novel coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has infected ~435 million people and caused ~6 million related deaths as of March 2022. To combat COVID-19, there have been many attempts to repurpose FDA-approved drugs or revive old drugs. However, many of the current treatment options have been known to cause adverse drug reactions.

Benzodipyrrole-2,6-dione-3,7-diylidenedimalononitrile Derivatives for Air-Stable -Type Organic Field-Effect Transistors: Critical Role of -Alkyl Substituent on Device Performance.

Benzodipyrrole-2,6-dione-3,7-diylidenedimalononitriles (BDPMs) were synthesized as active materials for the use in air-stable -type organic field-effect transistors (OFETs), whose optical and electrochemical properties were examined. BDPM-based small molecules exhibit deep lowest unoccupied molecular orbital levels, which are required in air-stable -type OFETs. An OFET device that was based on and fabricated by vapor deposition provided a maximum electron mobility of 0.

Angular-Shaped Naphthalene Bis(1,5-diamide-2,6-diylidene)malononitrile for High-Performance, Air-Stable N-Type Organic Field-Effect Transistors.

The synthesis, characterization, and application of two angular-shaped naphthalene bis(1,5-diamide-2,6-diylidene)malononitriles (NBAMs) as high-performance air-stable n-type organic field effect transistor (OFET) materials are reported. NBAM derivatives exhibit deep lowest-unoccupied molecular orbital (LUMO) levels, suitable for air-stable n-type OFETs. The OFET device based on NBAM-EH fabricated by vapor deposition exhibits a maximum electron mobility of 0.

Generation of novel induced pluripotent stem cell (iPSC) line from a 16-year-old sialidosis patient with NEU-1 gene mutation.

Sialidosis is a rare autosomal recessive disorder that affects the intralysosomal catabolism of sialylated glycoconjugates and is involved in cellular immune response. Mutations in NEU1, which encodes the sialidase enzyme, result in sialidosis. Sialidosis is characterized by the progressive lysosomal storage of sialylated glycopeptides and oligosaccharides.

Generation of 2 induced pluripotent stem cell lines derived from patients with Parkinson's disease carrying LRRK2 G2385R variant.

Leucine rich repeat kinase (LRRK2) is the most prevalent genetic cause for Parkinson's disease. LRRK2 p.G2385R is an Asian specific genetic risk factor for sporadic Parkinson's disease.

Generation of an induced pluripotent stem cell (iPSC) line from a 40-year-old patient with the A8344G mutation of mitochondrial DNA and MERRF (myoclonic epilepsy with ragged red fibers) syndrome.

Mitochondrial defects are associated with clinical manifestations from common diseases to rare genetic disorders. Myoclonus epilepsy associated with ragged-red fibers (MERRF) syndrome results from an A to G transition at nucleotide position 8344 in the tRNA gene of mitochondrial DNA (mtDNA) and is characterized by myoclonus, myopathy and severe neurological symptoms. In this study, Sendai reprogramming method was used to generate an iPS cell line carrying the A8344G mutation of mtDNA from a MERRF patient.

Generation of an induced pluripotent stem cell line from a 39-year-old female patient with severe-to-profound non-syndromic sensorineural hearing loss and a A1555G mutation in the mitochondrial MTRNR1 gene.

Sensorineural hearing loss (SNHL) is a prevalent form of deafness commonly arising from damage to the cochlear sensory hair cells and degeneration of the spiral ganglion neurons. In this study, Sendai virus was used to generate an induced pluripotent stem cell (iPSC) line from a 39-year-old female patient diagnosed with severe-to-profound, non-syndromic SNHL. The patient also carries a A1555G mutation in the mitochondrial 12S ribosome RNA gene (MTRNR1).

Generation of induced pluripotent stem cells from a patient with Parkinson's disease carrying LRRK2 p.I2012T mutation.

Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by interactions between genetic and environmental factors. Leucine rich repeat kinase (LRRK2) is the most prevalent mutation in autosomal-dominant inheritance of PD. Here, we generated induced pluripotent stem cells (iPSCs) from the peripheral blood mononuclear cells of a female patient with p.

Induced pluripotent stem cells derived from an autosomal dominant polycystic kidney disease patient carrying a PKD1 Q533X mutation.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most prevalent monogenic kidney disorder leading to kidney failure. We generated induced pluripotent stem cells (iPSCs) from a 37-year-old man carrying a PKD1 Q533X mutation who suffered from kidney failure and a myocardial infarction. The iPSCs were reprogrammed from the patient's peripheral blood mononuclear cells using the Sendai virus system, and were confirmed to possess the specific PKD1 Q533X mutation and normal karyotype.

Generation of an induced pluripotent stem cell line, IBMS-iPSC-014-05, from a female autosomal dominant polycystic kidney disease patient carrying a common mutation of R803X in PKD2.

Autosomal dominant polycystic kidney disease (ADPKD) is one of the most commonly inherited forms of polycystic kidney disease, and is characterized by the growth of numerous cysts in both kidneys. Here we generated an induced pluripotent stem cell (iPSC) line from the peripheral blood mononuclear cells (PBMCs) of a 63-year-old female ADPKD patient carrying an R803X mutation in the PKD2 gene using the Sendai-virus delivery system. Downstream characterization of these iPSCs showed that they possessed normal karyotyping, were free of genomic integration, retained the disease-causing PKD2 mutation, expressed pluripotency markers and could differentiate into three germ layers.

Generation of induced pluripotent stem cells derived from an autosomal dominant polycystic kidney disease patient with a p.Ser1457fs mutation in PKD1.

Autosomal dominant polycystic kidney disease is one of the most prevalent forms of inherited cystic kidney disease, and can be characterized by kidney cyst formation and enlargement. Here we report the generation of a Type 1 ADPKD disease iPS cell line, IBMS-iPSC-012-12, which retains the conserved deletion of PKD1, normal karyotype and exhibits the properties of pluripotent stem cells such as ES-like morphology, expression of pluripotent markers and capacity to differentiate into all three germ layers. Our results show that we have successfully generated a patient-specific iPS cell line with a mutation in PKD1 for study of renal disease pathophysiology.

Comparative analysis of multiple inducible phages from Mannheimia haemolytica.

Background: Mannheimia haemolytica is a commensal bacterium that resides in the upper respiratory tract of cattle that can play a role in bovine respiratory disease. Prophages are common in the M. haemolytica genome and contribute significantly to host diversity.

Field scale evaluation of bovine-specific DNA as an indicator of tissue degradation during cattle mortality composting.

Currently, mortality compost is managed by temperature as extent of tissue degradation is difficult to assess. In the present study, field-scale mortality compost was constructed with composted brain tissue (Brain) and compost adjacent to brain tissue (CAB) sampled over 230 d. Following genomic DNA extraction, bovine-specific mitochondrial DNA (Mt-DNA) and bacterial 16S rDNA fragments were quantified using real-time PCR.
