    Abstract d-Glucose was converted into the orthogonally protected open-chain derivative having different blocks at both terminal positions: C1 and C6. Selective deprotection of the C1-position opened a route to intermediate with the D-gluco-configuration, while deprotection at the C6-position gave the L-gulo isomer. In both derivatives, the oxime functionality was installed at the proper terminal position, which produced the corresponding precursors of a family of 7-membered ring iminosugars. One of these oximes was converted into the direct precursor: 6,1-bromonitrile.

    Abstract Introduction: Traumatic brain injury (TBI) is one of the most common causes of death and an important burden to the worldwide healthcare system and society. There is a lack of guidelines for types of monitoring or neuroprotective therapy. The aim of this pilot study was to assess its feasibility and, furthermore, to evaluate the impact of Cerebrolysin on the following clinical outcomes: length of stay, Glasgow Outcome Scale (GOS) and mortality.
    Methods: A cohort of 56 patients was included in this non-randomised, real-time, pre-post-interventional study. The patients were assessed with the Glasgow Coma Scale (GCS) and divided into two groups: severe (GCS < 8) and non-severe (GCS > 8). After the radiological examination (CT scan), the patients were qualified for an immediate neurosurgical procedure if needed. The patients were admitted to the intensive care unit, where a standardised protocol for TBI treatment was implemented. Additional neuromonitoring was applied.
    Results: There were 56 patients (19 females; 33.9%), of which 41 were considered severe cases; the patients were allocated to the Cerebrolysin (
    Conclusions: A multimodal treatment approach with monitoring and Cerebrolysin may have a beneficial effect on patients with less severe TBIs; however, the present study has multiple limitations, and further research is needed.

    Abstract Hydrogels are attractive biomaterials for the controlled release of various pharmaceuticals, due to their ability to embed biologically active moieties in a 3D polymer network. Among them, agarose-based hydrogels are an interesting, but still not fully explored, group of potential platforms for controlled drug release. In this work, agarose hydrogels with various contents of citric acid were prepared, and their mechanical and physicochemical properties were investigated using various instrumental techniques, such as rheological measurements, attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR). Releasing tests for diclofenac sodium (DICL) were run in various environments; water, PBS, and 0.01 M NaOH; which remarkably affected the profile of the controlled release of this model drug. In addition to affecting the mechanical properties, the amount of citric acid incorporated within a hydrogel network during synthesis was also of great importance to the rate of DICL release. Therefore, due to their high biocompatibility, agarose hydrogels can be regarded as safe and potential platforms for controlled drug release in biomedical applications.

    Abstract Technological advances offer the opportunity to improve glycemic control and reduce the risk of complications and burden of type 1 diabetes while improving patient quality of life. Closed-loop insulin delivery systems take the technology to a larger scale by integrating CGM systems with an insulin pump and an algorithm that automates insulin delivery (HCL systems). Several systems using hybrid closed loop technology are currently offered in the global marketplace: the MiniMed™ 670G and MiniMed™ 780G (SmartGuard™) system from Medtronic; the T slim x2 Control IQ from Tandem; the Omnipod5 automated mode (HypoProtect™)5 from Insulet; and the CamAPS FX DanaRS or Ypso pump. Insulet's Omnipod5 automated mode (HypoProtect™) is currently in clinical trials. As technology moves forward, advanced systems are being developed that include an elaborate algorithm with individualization of major target points, automated correction bolus functionality, and increased stability of the automated mode (Advanced Hybrid Closed-Loop - AHCL systems). The AHCL systems include: MiniMed™ 780G (SmartGuard™); Tandem's T slim x2 Control IQ; Insulet's Omnipod5-Automated mode (HypoProtect™); and CamAPS FX. The purpose of this paper is to present commercial devices using HCL and AHCL in 2022, also from a scientific point of view. It is an undeniable fact that "auto-mode" systems represent a new stage that can be confidently called a revolution in diabetology.

    Abstract Copeptin (CTproAVP) is a stable by-product of arginine-vasopressin synthesis and reflects its secretion by the pituitary gland, considered as a potential new marker of dehydration. The objective of the study was to investigate CTproAVP measured after the first 48 h of postnatal life in relation to serum effective osmolality, urine osmolality, and vessels filling according to the following variables: delivery mode, postnatal weight loss, fluids administered intravenously to the mother, and fluids given orally to the neonate. A prospective observational study was conducted with 200 healthy term infants (53% male) enrolled. Serum CTproAVP concentrations were measured using the ELISA kit; haematocrit, urine osmolality, serum effective osmolality were assessed after 48 h of life. Sonographic measurements of inferior vena cava (IVC) and aorta (Ao) were performed and IVC/Ao ratios were calculated. No correlations were found between CTproAVP concentrations and both serum effective osmolality and urine osmolality. There was also no association between CTproAVP concentrations and vessel filling represented by IVC/Ao index at 48 h of life.

    Abstract Oxalate oxidase (EC 1.2.3.4) is an oxalate-decomposing enzyme predominantly found in plants but also described in basidiomycete fungi. In this study, we investigated 23 fungi to determine their capability of oxalic acid degradation. After analyzing their secretomes for the products of the oxalic acid-degrading enzyme activity, three groups were distinguished among the fungi studied. The first group comprised nine fungi classified as oxalate oxidase producers, as their secretome pattern revealed an increase in the hydrogen peroxide concentration, no formic acid, and a reduction in the oxalic acid content. The second group of fungi comprised eight fungi described as oxalate decarboxylase producers characterized by an increase in the formic acid level associated with a decrease in the oxalate content in their secretomes. In the secretomes of the third group of six fungi, no increase in formic acid or hydrogen peroxide contents was observed but a decline in the oxalate level was found. The intracellular activity of OXO in the mycelia of Schizophyllum commune, Trametes hirsuta, Gloeophyllum trabeum, Abortiporus biennis, Cerrena unicolor, Ceriosporopsis mediosetigera, Trametes sanguinea, Ceriporiopsis subvermispora, and Laetiporus sulphureus was confirmed by a spectrophotometric assay.

    Abstract The aim of this article is to outline the history of the scientific journal Gospodarka Narodowa, which from 1946 to 1989 operated under the name Gospodarka Planowa. The study pays particular attention to the subject matter of the articles published in the journal, the organisation of editorial work and the people associated with the journal. For this purpose, sources and existing studies were consulted, and an analysis was conducted of the citations of the papers published in the journal. When possible, the frequency of the use of selected JEL classification codes in the papers was also analysed. The article not only offers the first in-depth description of the nine decades of Gospodarka Narodowa, but also makes an original contribution to the discipline by indicating the most frequently cited articles published in the journal. It finds that the main areas of interest for Gospodarka Narodowa authors over the past decade have been issues related to macroeconomics, including monetary economics, international economics, financial economics, and economic growth. Another finding is that many authors have shown a preference for a clearly quantitative approach to the study of these problems. The article concludes by stating that Gospodarka Narodowa underwent a long evolution before it eventually became a strictly scientific journal, a focus that it has preserved to this day.

    Abstract Świadomość ekonomiczna młodzieży jest bardzo ważnym zagadnieniem mającym znaczący wpływ na ich decyzje konsumenckie (rynkowe). Według opinii Polaków, wśród czynników kształtujących świadomość ekonomiczną młodzieży istotną rolę przyjmuje edukacja formalna, tj. szkoła i nauczyciele. W systemie edukacji formalnej w Polsce, młodzież do 16. roku życia nie ma możliwości edukacji ekonomicznej, gdyż w programie nauczania nie ma wyodrębnionego przedmiotu z zakresu mechanizmów rynkowych, ekonomii i finansów. Właściwa edukacja w tym obszarze odbywa się na etapie szkoły ponadpodstawowej. W takich warunkach istotnego znaczenia nabiera edukacja nieformalna, polegająca m.in. na rozmowach w rodzinie na tematy gospodarowania środkami pieniężnymi i budżetem domowym. Wyniki badań wykazały, że tylko 30% badanych wskazuje, iż w domu odbywają się rozmowy na tematy ekonomiczne. Warto także podkreślić znaczący wpływ dostępności inicjatyw edukacji ekonomicznej w szkołach z utrudnionym dostępem do takich form aktywności, a zwłaszcza zastosowanych narzędzi i metod na wzrost wiedzy i umiejętności ekonomicznych młodzieży.
