Inflammatory bowel disease, including Crohn's disease and ulcerative colitis, poses an emerging threat as it can lead to colorectal cancer, thrombosis, and other chronic conditions. The present study demonstrated the protective effects of peanut sprout extracts (PSEs) prepared from day 2 to day 7 of germination against lipopolysaccharide (LPS)-induced epithelial barrier breakdown. Although the peanut sprout length increased in a time-dependent manner from day 1 to day 7, the extraction yields remained relatively consistent from day 2 to day 7.

Polymorphing hydrogels can morph into another structure on demand with reprogrammable features. This concept extends the degree of morphing beyond that of traditional shape-morphing hydrogels, which predetermine their morphing capabilities at the fabrication stage. However, current polymorphing hydrogels face limitations due to the need for complex, non-sustained responsiveness or additional chemical steps for reconfigurable morphing.

Oysters (Crassostrea gigas) are one of the most consumed shellfish globally. However, there is a lack of comprehensive microbiome studies that include the processing and distribution stages of oysters. The present study used both culture-based methods and 16S rRNA sequencing to produce comprehensive microbial profiles of oysters in two parts: (1) an oyster processing plant that processes raw and frozen oysters (n = 57) and (2) retail oyster products across two seasons (winter and spring) (n = 112).

Zika virus (ZIKV) infection is primarily transmitted by mosquitoes and often asymptomatic in most individuals. Infection during pregnancy can lead to severe birth defects such as congenital microcephaly, and currently, there is no approved vaccine for ZIKV. Several studies are investigating the development of ZIKV vaccine using DNA and RNA as well as recombinant protein technologies; however, the outcomes thus far have not been consistently noteworthy.

Article Synopsis
  • This study aimed to evaluate the impact of starting niraparib maintenance therapy early (within 8 weeks post-chemotherapy) versus later in patients with newly diagnosed advanced ovarian cancer.
  • The research found that early initiation of niraparib was linked to significantly better progression-free survival, especially when started within 6 weeks after chemotherapy completion.
  • However, early treatment was also associated with a higher rate of adverse events leading to treatment discontinuation, suggesting a trade-off between benefits and risks.

Respiratory Syncytial Virus (RSV) is a significant cause of lower respiratory tract infections (LRTI) across all demographics, with increasing mortality and morbidity among high-risk groups such as infants under two years old, the elderly, and immunocompromised individuals. Although newly approved vaccines and treatments have substantially reduced RSV hospitalizations, accessibility remains limited, and response to treatment varies. This underscores the importance of comprehensive studies on host-RSV interactions.

We developed a promising mRNA vaccine against severe fever with thrombocytopenia syndrome (SFTS), an infectious disease caused by the SFTS virus that is primarily transmitted through tick bites. Administration of lipid nanoparticle-encapsulated mRNA-Gn successfully induced neutralizing antibodies and T-cell responses in mice. The vaccinated mice were protected against a lethal SFTS virus challenge, suggesting that this mRNA vaccine may be an effective and successful SFTS vaccine candidate.

This perspective paper comprehensively explores recent electrochemical studies on layered transition metal oxides (LTMO) in aqueous media and specifically encompasses two topics: catalysis of the oxygen evolution reaction (OER) and cathodes of aqueous lithium-ion batteries (LiBs). They involve conflicting requirements; OER catalysts aim to facilitate water dissociation, while for cathodes in aqueous LiBs it is essential to suppress water dissociation. The interfacial reactions taking place at the LTMO in these two distinct systems are of particular significance.

The incompatibility of lithium intercalation electrodes with water has impeded the development of aqueous Li-ion batteries. The key challenge is protons which are generated by water dissociation and deform the electrode structures through intercalation. Distinct from previous approaches utilizing large amounts of electrolyte salts or artificial solid-protective films, we developed liquid-phase protective layers on LiCoO (LCO) using a moderate concentration of 0.

tRNA-derived RNA fragments (tRFs) are a recently discovered family of small noncoding RNAs (sncRNAs). We previously reported that respiratory syncytial virus (RSV) infection induces functional tRFs, which are derived from a limited subset of parent tRNAs, in airway epithelial cells. Such induction is also observed in nasopharyngeal wash samples from RSV patients and correlates to RSV genome copies, suggesting a clinical significance of tRFs in RSV infection.

The ongoing pandemic of coronavirus disease 2019 (COVID-19), which results from the rapid spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a significant global public health threat, with molecular mechanisms underlying its pathogenesis largely unknown. In the context of viral infections, small non-coding RNAs (sncRNAs) are known to play important roles in regulating the host responses, viral replication, and host-virus interaction. Compared with other subfamilies of sncRNAs, including microRNAs (miRNAs) and Piwi-interacting RNAs (piRNAs), tRNA-derived RNA fragments (tRFs) are relatively new and emerge as a significant regulator of host-virus interactions.
