A case of accidental Ricin poisoning [PDF]
A case report of accidental, mild ricin poisoning by ingestion of ten Castor beans by a 70 year old man. The clinical presentation is followed by a discussion about the toxicity of ricin, its use and misuse and the contrast between the toxicity of pure ...

Identification of a VapBC toxin–antitoxin system in a thermophilic bacterium Thermus thermophilus HB27 [PDF]
There are 12 putative toxin–antitoxin (TA) loci in the Thermus thermophilus HB27 genome, including four VapBC and three HicBA families. Expression of these seven putative toxin genes in Escherichia coli demonstrated that one putative VapC toxin TTC0125 ...

GCN2 in proteostasis: structural logic, signalling networks and disease
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Expression of the alpha-thionin gene from barley in tobacco confers enhanced resistance to bacterial pathogens [PDF]
Thionins are cysteine-rich, 5 kDa polypeptides which are toxic to plant pathogens in vitro. Expression of the gene encoding alpha-thionin from barley endosperm, under the 35S promoter from cauliflower mosaic virus, conferred to transgenic tobacco ...

The Role of Oxidative Stress in Periodontitis
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Summary Acclimation enables plants to adjust to immediate environmental fluctuations and is therefore key to the resilience of plant disease resistance in a time of climate change. Here, we report on the acclimation of Arabidopsis thaliana quantitative immune responses against the fungal pathogen Sclerotinia sclerotiorum to daily environmental ...

Plant Peptides on the Rise: From Historical Insight to Future Applications
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

Novel and emerging antimicrobial strategies in the management of oral infections
Abstract Background Antibiotics marked a pivotal turning point in human civilization, enhancing social interactions and extending human life expectancy. In addition to their success in treating systemic infectious diseases, they have significantly improved periodontal treatment outcomes as an adjunct therapy.

How Salmonella Works Under Osmotic and Desiccation Stresses
ABSTRACT Salmonella remains one of the leading threats in foods with reduced water activity, where it can survive for long periods and cause outbreaks. Its persistence stems from a wide array of adaptive strategies shaped by the selective pressures imposed by low‐moisture foods.
