Medical education in Syria at a time of crisis: Analysis of the results of the knowledge-based National Medical Examination.

Objective: This study explored how the Syrian crisis, training conditions, and relocation influenced the National Medical Examination (NME) scores of final-year medical students.

Methods: Results of the NME were used to denote the performance of final-year medical students between 2014 and 2021. The NME is a mandatory standardised test that measures the knowledge and competence of students in various clinical subjects.

Rhabdomyosarcoma or Fibrosarcoma? A Case of Large Ulcerated and Necrotic Lesion on the Forearm of a Newborn.

Congenital infantile fibrosarcoma (CIFS) is a rare malignant soft tissue tumor. The incidence of fibrosarcoma is estimated to be 0.3 per 100 000 population per year, and it accounts for less than 1% of all soft tissue sarcomas.

Depression, anxiety and related factors among Syrian breast cancer patients: a cross-sectional study.

Introduction: Breast cancer represents a traumatic experience with a psychological burden. The prevalence of psychological distress (which include depression and anxiety) among breast cancer patients is estimated to be 15 to 54%, but studies have shown that applying some psychological treatments has contributed to decreasing depression and anxiety. So, it is crucial to diagnose and treat patients with the appropriate means.

The role of interfacial films in the mass transfer of naphthalene from creosotes to water.

Viscous, semi-rigid interfacial films that are formed at the interface of certain multi-component non-aqueous phase liquid (NAPLs) and water can significantly reduce the rates of mass transfer of solutes. Creosote-water systems were investigated for their ability to form interfacial films. The effects of these films on the creosote-water partition and on mass transfer of a representative solute, naphthalene, were investigated in a series of experiments.

Reduction of benzene and naphthalene mass transfer from crude oils by aging-induced interfacial films.

Semi-rigid films or skins form at the interface of crude oil and water as a result of the accumulation of asphaltene and resin fractions when the water-immiscible crude oil is contacted with water for a period of time or "aged". The time varying patterns of area-independent mass transfer coefficients of two compounds, benzene and naphthalene, for dissolution from crude oil and gasoline were determined. Aqueous concentrations of the compounds were measured in the eluent from flow-through reactors, where a nondispersed oil phase and constant oil-water interfacial area were maintained.

Naphthalene biodegradation from non-aqueous-phase liquids in batch and column systems: comparison of biokinetic rate coefficients.

The kinetics of microbial degradation of naphthalene from a two-component non-aqueous-phase liquid (NAPL) coated onto uniformly sized nonporous particles were evaluated in a completely mixed batch reactor (CMBR) system and in flow-through column systems to examine the differences in the biodegradation kinetic coefficients, micro(max), the maximum specific growth rate coefficient, and K(s), the half saturation constant in the two systems. The values of these coefficients were estimated by nonlinear least-squares regression of the naphthalene mineralization profiles obtained from both CMBR and column biodegradation experiments. The results show that the range of values for micro(max) and K(s) obtained from column systems are very similar to the range of values obtained from CMBR systems.
