Plant Antimicrobial Peptides and Their Main Families and Roles: A Review of the Literature.

Antimicrobial peptides (AMPs) are constituent molecules of the innate defense system and are naturally produced by all organisms. AMPs are characterized by a relatively low molecular weight (less than 10 kDa) and a variable number of cysteine residues that form disulfide bonds and contribute to the stabilization of the tertiary structure. In addition, there is a wide repertoire of antimicrobial agents against bacteria, viruses, fungi, and protozoa that can provide a large number of prototype peptides for study and biochemical manipulation.

ZBP1 senses DNA triggering type I interferon signaling pathway and unfolded protein response activation.

The innate immune system promptly detects and responds to invading pathogens, with a key role played by the recognition of bacterial-derived DNA through pattern recognition receptors. The Z-DNA binding protein 1 (ZBP1) functions as a DNA sensor inducing type I interferon (IFN) production, innate immune responses and also inflammatory cell death. ZBP1 interacts with cytosolic DNA via its DNA-binding domains, crucial for its activation.

Changes in the intestinal microbiota induced by the postnatal environment and their association with hypertension.

It has been established that cross-fostering impacts the development of hypertension in spontaneously hypertensive rats (SHR). However, the ability of the cross-fostering protocol to shape gut microbiota profile in SHR and impact hypertension is not known. In this sense, the current study explored the influence of normotensive and hypertensive postnatal environments on the intestinal microbiota structure, composition, and functional capacity of SHR and Wistar rats.

Characterisation of periorbital mechanical allodynia in the reserpine-induced fibromyalgia model in mice: The role of the Schwann cell TRPA1/NOX1 signalling pathway.

Fibromyalgia (FM) is a complex and multifaceted condition characterized by a range of clinical symptoms, including widespread pain and a strong association with migraine headaches. Recent findings have underscored the role of oxidative stress and transient receptor potential ankyrin 1 (TRPA1) channel in migraine and FM. However, the precise mechanisms underlying the comorbidity between migraine and FM are unclear.

Quality of Life and Adaptation of People With a Colostomy Plug: A Before-After Interventional Study.

Purpose: The purpose of this study was to examine health-related quality of life and adaptation of persons with a colostomy before and after use of a colostomy plug.

Design: Single group before-and-after study.

Subjects And Setting: The study sample comprised 19 people with a colostomy who attended an outpatient clinic João Pessoa, in Paraiba, Brazil.
