In the crystal structure of the title molecular salt, C21H15FNO2
+·CF3SO3
−·H2O, the cations form inversion dimers through π–π interactions between the acridine ring systems. These dimers are linked via C—H⋯O and C—F⋯π interactions to adjacent anions, and by C—H⋯π and C—F⋯π interactions to neighbouring cations. The water molecule links two sites of the cation by C—H⋯O interactions and two adjacent anions by O—H⋯O hydrogen bonds. The mean planes of the acridine and benzene ring systems are oriented at a dihedral angle of 15.1 (1)°. The carboxyl group is twisted at an angle of 84.5 (1)° relative to the acridine skeleton. The mean planes of the acridine ring systems are parallel in the crystal
Evaluation of the effectiveness of Kinesiology Taping in the treatment of symptoms of gonarthrosis - a pilot study
The aim
Evaluation of the effectiveness of Kinesiology Taping in the treatment of gonarthrosis
Material and Methods
The study included 40 pacient with osteoarthritis of the knee joints, confirmed on the basis of a medical diagnosis. The subjects were randomly divided into two groups: Study group (n = 20) and control group (n = 20)
Patients in both groups before the study completed a questionnaire containing basic questions about gender, age, height and weight. The Body Mass Index (BMI) was calculated for all patients. Before and after therapy, both groups were:
• assessment of the level of pain, stiffness and functionality of the knee joint using the WOMAC scale;
• assessment of the functionality using the Time Up and Go test.
Results
In the group of patients who underwent the Kinesiology Taping application, significant reduction of pain and stiffness as well as improvement of knee function was demonstrated (WOMAC scale and the Time Up and Go test). In the control group, there were no statistically significant differences before and after therapy in all domains of the WOMAC scale, while a statistically significant worsening of the results of the Time up and Go test was demonstrated. Comparing the results of the study group and control after treatment, statistically significant differences were found - better results were obtained in the study group
Ekspresja genu DPP4 w raku brodawkowatym tarczycy
Introduction: DPP4 gene (dipeptidyl peptidase IV) is
expressed in epithelial cells of many organs and cells of
immune system. There is no expression of DPP4 in normal
healthy thyroid, while it is highly expressed in papillary
thyroid carcinoma (PTC), as shown by gene expression profiling.
In this study we validated expression of DPP4 in papillary
thyroid cancer and normal thyroid tissue and evaluated
its usefulness for diagnostic purposes.
Material and methods: The analysis was carried out on total
RNA extracted from 102 PTCs and 77 normal thyroid
fragments with use of Q-PCR reaction. Beta-glucuronidase was
the reference gene.
Results: We confirmed the distinct increase of DPP4 expression
in papillary thyroid carcinoma. However, the ROC (relative
operating characteristic) analysis revealed that the
diagnostic efficiency of DPP4 estimation is limited. Conclusions: DPP4 is increased in papillary thyroid cancer,
however, its diagnostic usefulness as a single PTC marker
is doubtful.Wstęp: Ekspresja genu DPP4 (dipeptydylopeptydazy IV) zachodzi
w komórkach nabłonkowych wielu niezmienionych
nowotworowo narządów oraz w komórkach układu immunologicznego.
W normalnej, zdrowej tarczycy nie stwierdza
się obecności DPP4, ale gen ten ulega silnej ekspresji
w brodawkowatym raku tarczycy, co wykazano w badaniach
mikromacierzowych.
W przedstawionej pracy przeprowadzono analizę ekspresji
genu DPP4 w raku brodawkowatym tarczycy (PTC, papillary
thyroid carcinoma) i utkaniu zdrowej tarczycy pod
kątem jego wartości jako markera molekularnego.
Materiał i metody: Materiał do badań stanowiło całkowite
RNA wyizolowane ze 102 guzów raka brodawkowatego
i z 77 fragmentów zdrowej tkanki tarczycy. Ekspresję genu
DPP4 badano, wykorzystując reakcję Q-PCR, równocześnie
z pomiarem beta-glukuronidazy jako genu odniesienia.
Wyniki: Otrzymane metodą Q-PCR wyniki wskazują wyraźny
wzrost ekspresji DPP4 w raku tarczycy i silnie znamienną
statystycznie różnicę między ekspresją w PTC
a tarczycą niezmienioną nowotworowo. Niemniej analiza
krzywych ROC (relative operating characteristic) wykazała ograniczoną przydatność diagnostyczną tego markera molekularnego.
Wnioski: Gen DPP4 wykazuje większą ekspresję w raku
brodawkowatym tarczycy w porównaniu z tarczycą prawidłową,
ale jako pojedynczy marker molekularny ma niewielką
wartość diagnostyczną
Construction of bionanoparticles with the use of a recombinant DNA vector-enzymatic system, containing artificial poliepitopic proteins, for the delivery of new generation vaccines
DNA/RNA amplification technologies, such as the Polymerase Chain Reaction have revolutionized modern biology, medical diagnostics and forensic analyses, among others. A number of alternative nucleic acids amplification methods have been developed, tailored to specific applications. Here we present a refined version of a DNA fragment amplification technology, which enables the construction of ordered concatemers in a head-to-tail-orientation. A very high number of DNA segments, at least 500 copies, can be consecutively linked. Other key features include: (i) the application of a dedicated vector-enzymatic system, including selected subtype IIS restriction endonucleases, which has been designed to automatically generate long Open Reading Frames and (ii) an amplification-expression vector with a built-in strong transcription promoter along with optimal translation initiation signals, which allow for a high level of expression of the constructed artificial poliepitopic protein. This highly advanced technology makes it possible to obtain ordered polymers of monomeric, synthetic or natural, DNA far beyond the capabilities of current chemical synthesis methods. The constructed poliepitopic proteins are further used for construction of several types of nanoparticles, including inclusion bodies and bacteriophages, containing multiple genetic fusion with poliepitopic proteins.The technology offers significant advances in a number of scientific, industrial and medical applications, including new vaccines and tissue pro-regenerative methods. The technology is protected by an international patent application and is available for licensing.

Alloimmunizacja u chorych na niedokrwistość autoimmunohemolityczną oraz genotypowanie krwinek czerwonych w celu udoskonalenia doboru krwi do przetoczeń
Wstęp: Autoprzeciwciała typu ciepłego występujące w surowicy chorych na niedokrwistość
autoimmunohemolityczną powodują niezgodność w próbie zgodności i utrudniają wykrycie
klinicznie istotnych alloprzeciwciał, stwarzając ryzyko hemolitycznego powikłania poprzetoczeniowego.
Dobór krwi do przetoczenia dla tych chorych wymaga szczególnych procedur dla
większego bezpieczeństwa transfuzji.
Materiał i metody: Analizowano częstość alloimmunizacji u 163 chorych z NAIH (155 z autoprzeciwciałami
typu ciepłego, 8 typu mieszanego). U wszystkich chorych określano fenotyp w antygenach
Rh, K, konieczny dla doboru krwi do przetoczenia, a u 53 spośród nich, badano ponadto fenotyp
Kidd, Duffy, S, s, k jak również stosowano metodę genotypowania krwinek czerwonych.
Wyniki: Alloprzeciwciała istotne klinicznie wykryto u 31 chorych (19%). Łącznie zidentyfikowano
42 przeciwciała o różnej swoistości (u 7 chorych występowały przeciwciała o dwóch lub
więcej swoistościach) z układów grupowych: Rh, Kell, Kidd, Duffy, MNS i LW. U 14 chorych
z alloprzeciwciałami, wykrycie ich wymagało uprzedniego wyadsorbowania autoprzeciwciał
z surowicy metodą auto- lub alloadsorpcji. W grupie 53 chorych, fenotyp Rh, K, Kidd i S udało
się określić u 37 (70%) w testach serologicznych, zaś fenotyp rozszerzony o antygeny Duffy, s i k,
tylko u 9 chorych (17%). Wyniki fenotypowania były zgodne z oznaczeniami genetycznymi.
U pozostałych chorych o rozszerzonym fenotypie wnioskowano na podstawie genotypowania,
ponieważ wyniki serologiczne nie były miarodajne - dwie populacje krwinek (przetoczenia
krwi w ostatnich 3 miesiącach) lub/i autoaglutynacja krwinek chorego.
Wnioski: Wprowadzenie metod genotypowania obok metod fenotypowania okazało się konieczne
dla ustalenia rozszerzonego fenotypu krwinek czerwonych u chorych z NAIH. Badania
te usprawniają dobór krwi do przetaczania i zwiększają bezpieczeństwo transfuzji.Background: The presence of warm autoantibodies in the sera of patients with autoimmune
haemolytic anaemia are the cause of incompatibility in the compatibility test, which produces
difficulties in the detection of clinically significant alloantibodies thus generating the risk of
haemolytic transfusion reactions. For such patients the selection of red cells for transfusion
requires special procedures to ensure safety.
Material and methods:Alloimmunization was analyzed in 163 AIHA patients (155 with
warm type and 8 with mixed type of autoantibodies). In all patients, red cell phenotyping for
Rh, K, was performed prior to transfusion and in 53 of them, red cells were phenotyped
additionally in Kidd, Duffy, S, s, k with genotyping as well.
Results: Clinically significant alloantibodies were found in 31 patients (19%). In all, 42 antibodies
of different specificities were identified (in 7 cases we detected antibodies with two or more
specificities) within the following blood group systems: Rh, Kell, Kidd, Duffy, MNS and LW. In
14 of the alloimmunized patients, auto- or alloadsorption was required for alloantibody detection.
In the group of 53 patients, phenotyping of Rh, K, Kidd and S antigens was successful in
37 patients (70%) with serological tests only, whereas the extended phenotype for Duffy, s, k
antigens was successful only in 9 patients (17%). In each case, the genotype results were consistent
with the phenotype. In the remaining patients, the results of extended phenotyping with serological
method proved unreliable, due either to mixed-field reactions (after recent transfusion < 3 months)
or autoagglutination. Genotyping was useful for predicting the phenotype in such cases.
Conclusions: In addition to phenotyping, genotyping of red cells is necessary for establishing the
extended phenotype in AIHA patients. Such procedure is important for blood transfusion safety
A practical approach to the ESC 2022 cardio-oncology guidelines. Comments by a team of experts: cardiologists and oncologists
The 2022 European Society of Cardiology (ESC) guidelines [1] are a comprehensive document, prepared jointly by experts in cardiology and oncology. In the case of an oncological patient, it is necessary to individualize care in relation to the cardiological condition, the stage of the cancer and the type of potential anti-cancer therapy. Cardiac care optimisation should be undertaken before the start of oncological therapy, and continued during oncological therapy, as well as long-term after its completion [2]. The published ESC Guidelines were supplemented with a practical comments of a team of polish cardiology and oncology experts
Toxic epidermal necrolysis
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), also known as Lyell’s syndrome, are rare, life- -threatening diseases that are characterised by extensive epidermal detachment, erosion of mucous membranes and severe systemic symptoms. In the majority of cases, the development of symptoms can be attributed to the use of drugs; therefore, the disease pathology is thought to be caused by a severe adverse reaction to drugs. The high mortality rate results primarily from the development of complications in the form of systemic infections and multiple organ failure. TEN and SJS affect all age groups, including newborns, infants and older children. The rarity of these syndromes has not permitted large, randomised studies, which has resulted in numerous difficulties in their diagnosis and management. Because the pathogenesis has not yet been established, the management and systemic treatment of these syndromes have not been standardised. The efficacy of the treatment options suggested has not been confirmed by clinical studies involving suitably large groups of patients, especially children.Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), also known as Lyell’s syndrome, are rare, life- -threatening diseases that are characterised by extensive epidermal detachment, erosion of mucous membranes and severe systemic symptoms.

Analysis of Muscle Activity Following the Application of Myofascial Release Techniques for Low-Back Pain—A Randomized-Controlled Trial
Introduction. Lumbosacral dysfunctions and the resulting pain syndromes, such as low-back pain (LBP), are one of the most common musculoskeletal problems being faced by society around the world. So far, a contributory role of thoracolumbar fascia (TLF) dysfunction in some cases of LBP has been suggested. Research also confirms that muscle resting activity level in the TLF area is increased in people with LBP. Myofascial release (MFR) is a therapeutic option offered to patients with chronic low-back pain (CLBP). The therapy aims to improve flexibility and sliding between layers of soft tissue, and thus decrease muscle activity, reduce pain intensity, and improve functional performance. Objective. This study aims to assess changes in resting activity of selected muscles within the TLF in a group of patients with CLBP immediately after a single MFR treatment and one month after the intervention. Methods. A total of 113 patients with CLBP completed the study. Simple randomization was applied to assign subjects to study groups. The experimental group (n = 59) underwent a single session of MFR therapy. No therapeutic intervention was applied to the control group (n = 54). Surface electromyography was used to evaluate positive treatment effects in patients immediately after receiving the therapy (experimental group) and after one month (experimental and control group). Results. A statistically reliable decrease in the activity of erector spinae (ES) and multifidus muscles (MF) was observed after a single session of MFR therapy. Effects of the treatment were present immediately after receiving the therapy and one month after the intervention. Conclusions. A single MFR treatment in patients with CLBP immediately reduces the resting activity levels of ES and MF. Results of measurements carried out one month after the treatment confirm that the therapeutic effects were maintained
Zespół Aspergera u bliźniąt – dylematy diagnostyczne i terapeutyczne. Opis przypadku
Podstawowym celem pracy jest przedstawienie losów bliźniąt prezentujących objawy zespołu Aspergera (ZA).
Początkowo chłopców leczono ambulatoryjnie (rozpoznanie: ZA), później trafili na Oddział Młodzieżowy Kliniki
Psychiatrii Rozwojowej, Zaburzeń Psychotycznych i Wieku Podeszłego Gdańskiego Uniwersytetu Medycznego
w celu rediagnostyki. Bliźnięta były poddawane zmiennym oddziaływaniom wychowawczym – z uwagi na
rozwód rodziców, rozpad rodziny i stratę osób znaczących dla systemu rodzinnego. Z powodu licznych
deficytów, zwłaszcza w funkcjonowaniu społecznym, chłopców badało szereg specjalistów, zawsze jednak
kończyło się to na etapie wstępnej diagnozy. Dzieci zostały włączone w walkę między byłymi małżonkami (swoimi
rodzicami), co przejawiało się m.in. negowaniem na przemian przez jednego i drugiego rodzica obserwowanych
nieprawidłowości w rozwoju dzieci oraz brakiem akceptacji dla ustalonego rozpoznania i zaleceń terapeutycznych.
Artykuł wzbogacono o część teoretyczną, wprowadzającą do zagadnienia określanego mianem zespołu
Aspergera. Zgodnie z aktualną wiedzą na temat zaburzeń autystycznych w klasyfikacji DSM-5™ scalono wszystkie
wyszczególniane uprzednio jednostki diagnostyczne we wspólne rozpoznanie: zaburzenie ze spektrum autyzmu
(ASD). Kryteria identyfikacji zaburzeń należących do ASD są jednak kontrowersyjne i dzielą ekspertów. Molloy
i Vasil uznają zespół Aspergera za odmienność neurologiczną, z której obecne oczekiwania społeczne uczyniły
zaburzenie. Levin i Schlozman kwestionują sposób dzielenia zachowań na te mieszczące się w granicach normy i te,
które należy już uznać za zaburzenie. Baron-Cohen twierdzi zaś, że zespół Aspergera nie jest niepełnosprawnością,
ale innym stylem poznawczym, innym sposobem myślenia
