Supernormal Stimulus Begging Calls of Brood-Parasitic Nestlings Depress the Parental Care in an Uncommon Host.

During the nestling period, brood-parasitic birds stimulate host parents to provide food through complex visual and auditory signals, including emitting supernormal stimuli in the form of begging calls to increase the feeding frequency. However, whether the begging calls of brood-parasitic nestlings act as a universal type of supernormal stimulus signal and their effects on less common host species still require further research. In this study, we used playback recordings to verify the impact of the begging calls of Common Cuckoo () nestlings on the parental care behavior of host Barn Swallow () parents.

An orally available M/TMPRSS2 bispecific inhibitor with potent anti-coronavirus efficacy in vivo.

Coronaviruses have caused three major endemics in the past two decades.

Meanwhile, limited studies have investigated the potential role of oxidative stress and inflammation in this link.

Oral barriers to food-derived active peptides and nano-delivery strategies.

Food-derived bioactive peptides are a class of peptides from natural protein. It may have biological effects on the human body and play a significant role in protecting human physiological health and regulating physiological metabolism, such as lowering blood pressure, lowering cholesterol, antioxidant, antibacterial, regulating immune activity, and so on. However, most of the natural food-derived functional peptides need to overcome a variety of barriers in the body to enter the blood circulation system and target to specific tissues to generate physiological activity.

Defining the features and structure of neutralizing antibody targeting the silent face of the SARS-CoV-2 spike N-terminal domain.

Research on virus/receptor interactions has uncovered various mechanisms of antibody-mediated neutralization against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, understanding of neutralization by antibodies targeting the silent face, which recognize epitopes on glycan shields, remains limited, and their potential protective efficacy in vivo is not well understood. This study describes a silent face neutralizing antibody, 3711, which targets a non-supersite on the N-terminal domain (NTD) of the spike protein.

Impact of habitual intake of glucosamine, fresh fruit, and tea on the risk of urolithiasis: A two-sample Mendelian randomization study.

NRF1-mediated mitochondrial biogenesis antagonizes innate antiviral immunity.

Mitochondrial biogenesis is the process of generating new mitochondria to maintain cellular homeostasis. Here, we report that viruses exploit mitochondrial biogenesis to antagonize innate antiviral immunity. We found that nuclear respiratory factor-1 (NRF1), a vital transcriptional factor involved in nuclear-mitochondrial interactions, is essential for RNA (VSV) or DNA (HSV-1) virus-induced mitochondrial biogenesis.
