An Achromobacter xylosoxidans strain from the Tripoli central hospital produced a unique metallo-β-lactamase, designated TMB-1, which is related to DIM-1 (62%) and GIM-1 (51%). bla(TMB-1) was embedded in a class 1 integron and located on the chromosome. The TMB-1 β-lactamase has lower k(cat) values than both DIM-1 and GIM-1 with cephalosporins and carbapenems. The K(m) values were more similar ...

We present the spatial architecture of a new anhydrous polymorph of Acyclovir, obtained by rapid evaporation of a solution composed of Acyclovir and methanol. X-ray powder diffraction (XRPD), solid-state NMR (SSNMR), differential scanning calorimetry (DSC), and FTIR spectroscopy have been used as experimental tools to prove the formation of this new solid form and to characterize its crystallin...

Clindamycin has been used successfully to treat pneumonia and soft-tissue infections caused by methicillin-resistant Staphylococcus aureus. However, inducible clindamycin resistance has been described as a cause of treatment failure of such infections. A total of 159 staphylococcal isolates from different clinical specimens from burn patients in Tripoli Burn Center were tested for inducible cli...

This paper presents the conclusions of a study on the impact of ICT on collaborative learning processes in Libyan Higher Education (LHE). The quantitative analysis of the answers to a questionnaire (completed by Libyan full-time lecturers at the universities of Tripoli, Garyounis, Gharian and Ezawia) shows the necessity to design and develop more classroom activities and interactive online appl...

Seven hundred and twenty school children of primary school grades 5 and 6 in Hadba Sargia area in Tripoli were examined for dental caries. The mean DMFT index for the whole sample of children was 1.58. The DT component comprised 1.34 and MT component 0.21 of DMFT score, which made 42.22% and 13.33% of total children sample, respectively. The amount FT component was 0.03 (1.39%) of all children ...

Establishing mechanistic understanding of crystallization processes at the molecular level is challenging, as it requires both detection transient solid phases and monitoring evolution liquid a function time. Here, we demonstrate application dynamic nuclear polarization (DNP) enhanced NMR spectroscopy to study under nanoscopic confinement, revealing viable approach interrogate different stages ...

Gold miners exposed to crystalline silica are at risk of silicosis, lung cancer, and experience higher incidence rates of pulmonary tuberculosis (TB). Although the hazards associated with mercury exposure in artisanal small-scale gold mining (ASGM) have been well documented, no published data was available on crystalline silica exposures in this population. Air sampling was conducted in the bre...

An analysis was conducted on a cohort of Chinese pottery workers to estimate the exposure-response relationship between respirable crystalline silica dust exposure and the incidence of radiographically diagnosed silicosis, and to estimate the long-term risk of developing silicosis until the age of 65. The cohort comprised 3,250 employees with a median follow-up duration of around 37 years. Inci...
