Uncovering the Chemical Composition and Biological Potentials of Hornem. from Jordan.

The current study was designed to uncover the chemistry and bioactivity potentials of growing wild in Jordan. In this context, the fresh aerial parts obtained from the plant material were subjected to hydrodistillation followed by GC/MS analysis. The main components of the HDEO were γ-patchoulene (23.

Isolation of a new flavonoid from L. with evaluation of its potential biological activities.

In line with the importance of L. (Lamiaciatae) in traditional medicine as a calming and sedative remedy, the present study was designed to reveal its chemical constituents and bioactivity potentials. Thus, after extraction and fractionation of the plant material, the obtained butanol fraction (BPm) was subjected to conventional chromatographic separation of its constituents in addition to LC-MS/MS evaluation versus some authentic standards.

Emergence and Genomic Characterization of a Type t4407 ST6-SCC Type IVa Methicillin-Resistant Strain Isolated from Al-Karak Hospital, Jordan.

: Methicillin-resistant (MRSA) is a major concern in Jordanian hospitals in terms of infection control. The purpose of this study was to identify the resistance patterns of strains isolated from surfaces of critical locations within the Al-Karak Governmental Hospital in 2019. Additionally, the study aimed to conduct whole-genome sequencing on the isolates.

Production of medium-sized chitosan oligomers using molecular sieves and their antibacterial activity.

Chitosan, derived from the natural polysaccharide chitin, was fragmented in very dilute acetic acid solutions using zeolites and molecular sieves, a type of zeolites, under variable reaction conditions of temperature, acid concentration, duration of reaction, and zeolites of variable pore sizes. Fragmentation resulted in the formation of appreciable amounts of chitosan oligomers comprised of 4-8 units, which were studied by using LC-MS, MS, as well as IR spectroscopy. The prepared fragments were tested for their biological activity and some of them showed antibacterial activity against Gram-positive bacteria.

Green Synthesis of Silver Nanoparticles Using L. Aqueous Extract with the Evaluation of Its Antibacterial Activity against Clinical and Food Pathogens.

The rapid development of nanotechnology and its applications in medicine has provided the perfect solution against a wide range of different microbes, especially antibiotic-resistant ones. In this study, a one-step approach was used in preparing silver nanoparticles (AgNPs) by mixing silver nitrate with hot (St. John's wort) aqueous extract under high stirring to prevent agglomeration.

Antibacterial, antioxidant, and cytotoxic activities of (L.) Merr. & Perry essential oil with identification of its chemical constituents.

Aromatic plants embrace volatile compounds with efficiency in treating different diseases. In Jordan, flower buds (clove) are extensively used as folk medicine without awareness of its bio-safe dosage. Herein, clove buds were hydrodistilled using the Clevenger apparatus, and the resulting essential oil (CEO) was analyzed using Gas Chromatography-Mass Spectrometry (GC-MS).

infection in patients hospitalised for community-acquired pneumonia in Southern Jordan.

Purpose: Chlamydia pneumoniae is associated with human respiratory diseases. Few reports examined the involvement of this bacterium in community-acquired pneumonia (CAP) in Jordan. This study investigates for the first time the role of C.
