Repurposing is a universal mechanism for innovation, from the evolution of feathers to the invention of Velcro tape. Repurposing is particularly attractive for drug development, given that it costs more than a billion dollars and takes longer than ten years to make a new drug from scratch. The COVID-19 pandemic has triggered a large number of drug repurposing activities.

Article Synopsis
  • The use of biomaterials in medicine has improved drug delivery and decreased complications in procedures like transplantations and hemodialysis, but immune reactions remain a challenge.
  • Factor H (FH), a protein that regulates the complement system and dampens immune responses, can be recruited to biomedical surfaces using a cyclic peptide called 5C6, which helps reduce immune activation.
  • This research identifies the key structural elements of 5C6 necessary for effective binding to FH, enhancing its potential application as a therapeutic tool to minimize complement activation on biomaterials.

Wheat is a major nutritional cereal crop that has economic and strategic value worldwide. The sustainability of this extraordinary crop is facing critical challenges globally, particularly leaf rust disease, which causes endless problems for wheat farmers and countries and negatively affects humanity's food security. Developing effective marker-assisted selection programs for leaf rust resistance in wheat mainly depends on the availability of deep mining of resistance genes within the germplasm collections.

Climate change has increasing effects on horticultural crops. To investigate the impact of CO2 and temperature at elevated levels on tomato production and quality of fruits an experiment was conducted by growing plants in open top chambers. The tomato plants were raised at EC (elevated CO at 550 ppm) and EC (elevated CO at 700 ppm) alone and in combination with elevated temperature (ET) + 2 °C in the open top chambers.

Food borne pathogens cause serious human illnesses and diseases and their control using natural bioactive compounds becomes essential for the progress of agricultural and food industries. Developing novel tools to enhance the medicinal values of traditional horticultural medicinal crops is one of the promising methods for achieving food borne pathogens control. In this study, oligosaccharide water solutions were applied to Creme Brulee and Mahogany subjected to a normal irrigation interval (2 days) or to prolonged irrigation intervals (6 days) for 6 weeks.

Salinity stress as a major agricultural limiting factor may influence the chemical composition and bioactivity of L. essential oils and leaf extracts. The application of salicylic acid (SA) hormone may alleviate salinity stress by modifying the chemical composition, gene expression and bioactivity of plant secondary metabolites.

The negative effects of the ongoing climate change include unusual prolonged droughts and increased salinity pressures on the agricultural lands. Consequently, crops are facing unprecedented environmental pressure, and this calls for more research toward controlling such major stresses. The current study investigates the effects of seaweed extract sprays of (5 and 7 mL·L; 6 day intervals) on Salam' during prolonged irrigation intervals (2 and 6 day) and saline growing conditions (1 and 49.

Upper gastrointestinal tract (GIT) symptoms are not disease specific and of limited value in the differentiation of GIT disorders. The present study aimed to determine the etiology of chronic unspecific symptoms in children and to test the need for upper endoscopy in diagnosis. This is a prospective study for 30 Egyptian children presented with chronic upper GIT symptoms for at least 2 months.

Background/aims: An association of type 1 DM and familial Mediterranean fever (FMF) has been newly reported in the medical literature. The aim of the present work was to investigate frequency of MEFV gene mutations in Egyptian children with type 1 diabetes mellitus.

Methods: Forty five children with type 1 DM were screened for Mediterranean Fever (MEFV) gene mutation.
