Viruses

December 2024

Instituto Gonçalo Moniz, Fundação Oswaldo Cruz, Rua Waldemar Falcão, 121, Candeal, Salvador 40296-710, Bahia, Brazil.

The HIV-1 epidemic in Brazil is predominantly characterized by subtype B, except in the southern states, where subtype C (HIV-1C) is more prevalent. Continuous monitoring of this profile is essential to maintain an accurate understanding of the molecular landscape of the HIV epidemic in Brazil. In this study, we isolated and sequenced seven new HIV-1C strains from the state of Bahia, located in the Northeast region of Brazil.

Vesicular stomatitis virus (VSV) represents a significant advancement in therapeutic medicine, offering unique molecular and cellular characteristics that make it exceptionally suitable for medical applications. The bullet-shaped morphology, RNA genome organization, and cytoplasmic replication strategy provide fundamental advantages for both vaccine development and oncolytic applications. VSV's interaction with host cells through the low-density lipoprotein receptor (LDL-R) and its sophisticated transcriptional regulation mechanisms enables precise control over therapeutic applications.

Objectives: SARS-CoV-2 infection is a known risk factor for adverse health outcomes in pregnancy, affecting both maternal and neonatal health. Mounting evidence suggests that even a single dose of an approved COVID-19 vaccine protects against severe SARS-CoV-2 infection and is safe for both pregnant persons and neonates. Southern Brazil was heavily affected by the COVID-19 pandemic, and the protective effects of the vaccine on maternal and neonatal health are not well described.

Biological tissue defects are typically characterized by various shaped defects, and they are prone to inflammation and the excessive accumulation of reactive oxygen species. Therefore, it is still urgent to develop functional materials which can fully occupy and adhere to irregularly shaped defects by injection and promote the tissue repair process using antioxidant and anti-inflammatory mechanisms. Herein, in this work, phenylboronic acid modified oxidized hyaluronic acid (OHAPBA) was synthesized and dynamically crosslinked with catechol group modified glycol chitosan (GCHCA) and guar gum (GG) into a hydrogel loaded with curcumin liposomes (Cur-LPs) which were relatively uniformly distributed around 180 nm.

Large-scale epidemiological studies on the association of blood lead levels with blood pressure and hypertension prevalence are still limited, particularly among lead-exposed workers. The evidence is even more scarce on the interaction of blood lead levels with occupational variables and ambient air pollution levels. We developed mixed-effect models based on a large group of lead-exposed workers (N = 22,002).

Background: Thrombotic microangiopathy (TMA) is a potentially life-threatening complication associated with carfilzomib, a proteasome inhibitor approved for treating multiple myeloma. TMA typically presents within the initial months of treatment; however, delayed onset is rare and poses significant diagnostic challenges.

Methods: We conducted a retrospective analysis of the medical records of a 47-year-old Caucasian woman diagnosed with IgA kappa myeloma who developed signs and symptoms consistent with TMA eleven months after the initiation of carfilzomib therapy and already in ongoing very good partial remission.

Background: Durazz. is one of the most popular herbs used for depression treatment, but the molecular basis for its mechanism of action has not been fully addressed. Previously, we isolated and identified two lignan glycoside derivatives that were shown to noncompetitively inhibit serotonin transporter (SERT) activity but with a relatively low inhibitory potency compared with those of conventional antidepressants.

The stability of RNA is a critical factor in determining its functionality and degradation in the cell. In recent years, it has been shown that the stability of RNA depends on a complex interaction of external and internal factors. External conditions, such as temperature fluctuations, the level of acidity of the environment, the presence of various substances and ions, as well as the effects of oxidative stress, can change the structure of RNA and affect its stability.

As an important carrier of intercellular information transmission, exosomes regulate the physiological and pathological state of local or distant cells by carrying a variety of signal molecules such as microRNAs (miRNAs). Current research indicates that exosomes and miRNAs can serve as biomarkers and therapeutic targets for a variety of cardiovascular diseases (CVDs). This narrative review summarizes the research progress of exosomes and their miRNAs in CVDs, particularly in pulmonary valve diseases (PVDs), and, for the first time, explores their potential associations with transcatheter pulmonary valve replacement (TPVR).
