Chicory species, particularly Cichorium endive Supp. Pumillum, also, known as Egyptian chicory, are globally recognized for their rich content of bioactive secondary metabolites such as flavonoids and phenolics. These metabolites are highly valued for their pharmaceutical, dietary, and commercial applications.

Aim: The aim of this study is to investigate the neuroprotective effect of roflumilast, a phosphodiesterase-4 (PDE-4) inhibitor on cognitive impairment induced by doxorubicin (DOX)/cyclophosphamide (CP) combination therapy and to elucidate its modulatory effect on the pyroptosis pathway.

Materials And Methods: Rats were allocated into five groups: a control group, a DOX/CP-intoxicated group, two groups receiving DOX/CP plus low-dose (0.5 mg/kg/day) or high-dose (1 mg/kg/day) roflumilast, and a roflumilast-only group.

Objectives: The aim of this study is to screen for, isolate and characterize a bacteriophage designated ɸEcM-vB1 with confirmed lytic activity against multidrug-resistant (MDR) E. coli. Methods done in this research are bacteriophage isolation, purification, titer determination, bacteriophage morphology, host range determination, bacteriophage latent period and burst size determination, genomic analysis by restriction enzymes, and bacteriophage total protein content determination.

Article Synopsis
  • Pneumomediastinum, often occurring silently post-trauma, complicates diagnoses especially when paired with other conditions like pneumothorax and pneumoperitoneum, largely due to the Macklin effect where air escapes from ruptured alveoli.
  • An 18-year-old male involved in a car crash was found with severe pneumothorax and subcutaneous emphysema but showed no signs of significant esophageal or bronchial injury upon further evaluation.
  • Despite alarming initial imaging, the patient's treatment was conservative, allowing for a gradual healing process and eventual discharge without complications, illustrating the need for careful assessment in trauma management.

The design and synthesis of unique two series of fluorinated sulfonamides 3a-f and 5a-g utilizing nucleophilic aromatic substitution reactions of tetrafluorophthalonitrile 1 with various sulfonamides 2 under a variety of different reactions conditions were the key goals of the current research. The chemical composition of the generated products has been investigated via mass spectroscopy, HNMR, CNMR, infrared, and elemental analyzes. Antimicrobial studies were conducted in vitro to evaluate the activity of all new synthesized compounds against resistant strains.
