However, the percentage of sense vsiRNAs was significantly higher in the 25-26 nt long vsiRNAs. Distinct vsiRNA hotspots, identifying highly abundant reads of different unique vsiRNA sequences, were observed in both viral genomes. Previous studies found an A or U bias at the 5' terminal nucleotide position of 21 nt vsiRNAs; in contrast, our analysis revealed a C and U nucleotide bias. This study provides insights that will help further elucidate differential processing of vsiRNAs in plant antiviral defense.Capsule summary word count None. Frontalfibrosing alopecia (FFA) is a chronic cicatricial alopecia with unknown etiology and a worldwide rising incidence. The objective of this study was to evaluate the association of FFA with demographic and exposure factors in a Brazilian multiracial population. A multicenter case-control study was conducted in 11 referral centers throughout Brazil. The study was a case-control study that prospectively recruited 902 participants (451 patients with FFA and 451 sex-matched control individuals). Study participants completed a thorough questionnaire comprising variables grouped as baseline demographics, environmental exposure, diet, hormonal factors, allergies, and hair and skin care. When adjusted by sex, age, menopause, and skin color, FFA was associated with hair straightening with formalin (odds ratio [OR], 3.18), use of ordinary (nondermatologic) facial soap (OR, 2.09) and facial moisturizer (OR, 1.99), thyroid disorders (OR, 1.69), and rosacea (OR, 2.08). Smokers (OR, 0.33) and users of antiresidue/clarifying shampoo (OR, 0.35) presented a negative association with FFA. There was no association with the use of sunscreen. Recall bias. The association with moisturizers, ordinary facial soap, and hair straightening with formalin and the negative association with antiresidue/clarifying shampoo reinforce the possibility of an exogenous particle triggering FFA. The association with moisturizers, ordinary facial soap, and hair straightening with formalin and the negative association with antiresidue/clarifying shampoo reinforce the possibility of an exogenous particle triggering FFA.The World Health Organization (WHO) has declared a pandemic caused by a new coronavirus named SARS-CoV-2. The growing demand for commercial kits used for automated extraction of SARS-CoV-2 RNA, a key step before rRT-PCR diagnosis, could cause a shortage of stocks that hinders the rapid processing of samples. Although the recommendation is to use automated methods for nucleic acid extraction, alternatives are necessary to replace commercial kits. However, these alternatives should be as reliable as automated methods. This work describes a simple method to detect SARS-CoV-2 from specimens collected in different preservation media. Samples were previously inactivated by heating and precipitating with a PEG/NaCl solution before rRT-PCR assays for Orf1ab, N and S genes. The new method was compared with an automated protocol of nucleic acid extraction. Both procedures showed similar analytical results. Consequently, this simple and inexpensive method is a suitable procedure for laboratory diagnosis of SARS-CoV-2 infection.l-Dopa Decarboxylase (DDC) is a pyridoxal requiring enzyme that catalyzes the decarboxylation of L-3,4-dihydroxyphenylalanine (l-Dopa) to Dopamine (DA). The function of DDC in physiological and pathological biochemical pathways remains poorly understood, while the function and regulation of human DDC isoforms is almost completely elusive. We have shown that Annexin V, a fundamental apoptosis marker, is an inhibitor of l-Dopa decarboxylase activity. Here we show the interaction of both the full-length DDC and the truncated isoform alternative DDC (Alt-DDC) with Annexin V in human tissue and cell lines. Interestingly, DDC isoform expression is enhanced or remains unaffected following staurosporine (STS) treatment, despite increased le
