In this paper, a highly efficient and straightforward method for synthesizing novel Schiff bases was developed by reacting selected biogenic amines with sodium 2-formylbenzene sulfonate and sodium 3-formylbenzene sulfonate. H and C NMR, IR spectroscopy, and high-resolution mass spectrometry were used to characterize the new compounds. The main advantages of the proposed procedure include simple reagents and reactions carried out in water or methanol and at room temperature, which reduces time and energy.

In this study, graphene flakes were obtained using an electrolytic method and characterized using X-ray diffraction (XRD), Raman and FTIR spectroscopy, scanning and transmission electron microscopy (SEM/TEM). Graphene-based composites with varying concentrations of 0.5%, 1% and 3% by weight were prepared with acrylic paint, enamel and varnish matrices.

Unlabelled: Parental perspective on the health, safety, and quality of life in children and adolescents with cystic fibrosis (CF).

Aim Of The Study: Assessment of the impact of a chronic disease such as cystic fibrosis (CF) on the quality of life and safety of children and adolescents as perceived by parents/caretakers.

Methods: The study was conducted at the Department of Lung Diseases of the Institute of Mother and Child, a branch of the Cystic Fibrosis Centre Children of Warsaw SZPZOZ in Dziekanów Leśny, the largest pediatric CF center in Poland, and in the Rodzinamuko group on Facebook.

Article Synopsis
  • Developed a bi-functional Bacterial-Nano-Cellulose (BNC) carrier system to cultivate cells from a medicinal plant that produces antimicrobial compounds.
  • The BNC was created over different durations (3, 5, or 7 days) and tested in three forms: unpurified, partially cleaned, and fully purified.
  • Results showed the 3-day-old, unpurified BNC had the highest levels of beneficial compounds and exhibited anti-inflammatory and antimicrobial properties, suggesting its use in treating local infections.

Background: Incidence of difficult endotracheal intubation ranges between 3 and 10%. Bougies have been recommended as an airway adjunct for difficult intubation, but reported success rates are variable. A new generation flexible tip bougie appears promising but was not investigated so far.

Introduction: Airway management is one of key elements of resuscitation. Endotracheal intubation is still considered the gold standard for airway management during resuscitation.

Aim: The aim of the study was to compare success rates and intubation time of different endotracheal intubation methods during emergency intubation with difficult airways in the conditions of cardiopulmonary resuscitation in a standardized manikin model.

Background: Treatment of the aortic arch pathologies is technically challenging. In this study we assess early and late outcomes of hybrid aortic arch repairs that comprise extra-anatomic surgical procedures completed by thoracic endovascular interventions [thoracic endovascular aortic repair (TEVAR)].

Methods: Since 2007, 21 patients (8 women and 13 men) with a median age of 48 years have undergone hybrid procedures for aortic arch pathologies.

The contamination of commonly used supplements by unknown steroids as well as their metabolites (parent compounds) become a challenge for the analytical laboratories. Although the determination of steroids profile is not trivial because of the complex matrix and low concentration of single compound, one of the most difficult current problem is to distinguish, during analytical procedure, endogenous androgens such as testosterone, dehydrotestosterone or dehydroepiandrosterone from their synthetic equivalents. The aim of this work was to develop and validate an analytical procedure for determination of the steroid profile in human urine by gas chromatography-combustion-isotope ratio mass spectrometry (GC/C/IRMS) toward distinguishing between endogenous and exogenous steroids.

Alfons Bukowski (1858-1921) is commonly regarded as the pioneer of anti-doping research. In 1910, he developed a method to detect alkaloids in horse saliva. One hundred years later, this is a good moment to remember Bukowski, an outstanding Polish pharmacist, often mistakenly represented in world literature as a Russian chemist.

The report presents the case of a sportswoman who accused her coach of having administered to her doping substances. During the judicial proceedings, biological samples of urine and hair were collected from this sportswoman. In the urine sample, a nandrolone metabolite was detected, but the result of hair analysis was negative.
