Introduction and objective. Pain is an integral element of the pathogenic process and sometimes determines its course. Disorders in pain sensation, as well as its lack, the pain threshold, and variability in sensation of the same pain stimuli as more or less intensive by different persons, may be genetically conditioned. The aim of the study is to examine genes in pathogenesis of chronic pain. Materials and method. The study was conducted in a specially selected group of 31 persons: study group – 20 patients with chronic pain, and control group – 11 healthy individuals who did not experience pain. The control group of 11 healthy persons, compared with the study group, was the catalyst for determining the relative quantification (RQ) of gene expression. Biological material in the form of venous blood was collected from the study participants into the tubes containing anticoagulant EDTA KE/2.7 ml (ethylenediaminetetraacetic acid), preventing extracorporeal blood clotting. Results. Analysis of expression of the examined genes showed over-expression of the DRD1 gene in patients experiencing chronic pain, which means that in these patients an increased number of dopamine D1 receptors encoded by this gene should be expected. The dopamine D1 receptor is a G-protein-coupled receptor which regulates (stimulates or inhibits) adenyl cyclase – the enzyme responsible for synthesis of cyclic AMP (cAMP). An increase in the concentration of cAMP in neurons enhances the sensation of pain. Conclusions. The genes (DRD1, COMT, OPRK1, HCN2) have a significant role in the pathogenesis of chronic pain in various diseases; they can also influence the perception of pain. Knowledge of these genes can contribute to the development of effective methods of combating pain.

Opis:
Introduction. pre-eclampsia is a pregnancy-related syndrome characterized by hypertension and proteinuria that makes its appearance after 20 weeks of gestation. It develops approximately in 2–10% of all pregnancies. Pre-eclampsia, as a severe complication during pregnancy, is a major cause of maternal and perinatal morbidity and mortality. Objectives. The aim of the study was to assess the possibility of utilizing selected microRNAs at the earliest possible stage as safe biomarkers of severe complications of pregnancy, such as pre-eclampsia. State of konowledge. Nowadays, there are many trials aimed at finding effective methods for pre-eclampsia prediction at the early stage of pregnancy, before the onset of clinical signs. Although the precise pathophysiology of pre-eclampsia remains unknown, early prediction of the syndrome would allow the initiation of proper preventive therapy to savethe mother and future child. Current strategies for pre-eclampsia prediction are assessments of combinations of maternal risk factors, ultrasound parameters and different biomarkers (proteins, circulating cell free DNA and microRNAs). Studies of microRNAs in particular offer great potential for diagnosis and therapy in pregnancy-related disorders. The fraction of specific placenta-related circulating microRNAs in the serum of pregnant women who present symptoms of pre-eclampsia after 20 weeks of gestation, and show the strongest changes in the level, can play an important role in the development of placenta-related complications. Conclusion. Further research into the level of microRNAs in the blood serum of pregnant women with pre-eclampsia will allow a practical way of utilizing selected microRNAs at the earliest possible stage as safe biomarkers of severe complications of pregnancy.

Introduction and objective. Heat stress induces the expression of genes encoding heat-shock proteins and immune response mediators. The aim of this study was to determine the differences in the expression of genes encoding heat-shock proteins 70 kDa and27 kDa, interleukin 6, interleukin 10and C-reactive protein, between athletes and non-athletes after sauna bathing. Materials and method. Athletes (n=9) and non-athletes (n=9) were exposed to a Finnish sauna twice during one session at a temperature of 98.2 °C and humidity of 10% ± 2%, with a 5 min break for cooling down under a shower. The groups did not differ in terms of age, height or body mass. Blood samples were taken before and after sauna exposure in order to assess gene expression, using reverse transcription polymerase chain reaction. Results. Differences were observed in leukocyte mRNA levels of tested genes between athletes and non-athletes. In the non-athlete group, all the tested genes were expressed at higher levels as a response to the same heat challenge. Conclusion. It appears that expression of stress-related genes induced by heat stress is dependent on the level of physical activity.

Opis:
A total of 684 Ixodes ricinus ticks (321 nymphs, 184 males, and 179 females) were collected by fl agging lower vegetation in 6 forest districts located on the territory of Lublin province (eastern Poland). Ticks were examined by polymerase chain reaction (PCR) method for the presence of Anaplasma phagocytophilum DNA with two pairs of primers: EHR521/EHR747 for detecting 16S rRNA gene, and LA6/LA1 for detecting ankA gene. To study the relationship between infection in ticks and people occupationally exposed to tick bite, blood serum samples of 261 forestry workers employed in the same forest districts were examined by immunofl uorescence method for the presence of specifi c antibodies against A. phagocytophilum. A total of 70 ticks out of 684 examined (10.2%) showed the presence of A. phagocytophilum 16S rRNA gene. The prevalence of infection was signifi cantly dependent on tick’s stage (χ2=49.2, p<0.00001) and geographical locality (χ2=34.4, p<0.00001). The percentage of I. ricinus females infected with A. phagocytophilum (24.6%) was signifi cantly greater compared to males (6.5%) and nymphs (4.4%) (p<0.00001). Only 19 ticks out of 684 examined (2.8%) showed the presence of A. phagocytophilum ankA gene, signifi cantly less compared to 16S rRNA gene (p<0.00001). The prevalence of infection demonstrated by the presence of ankA gene was also signifi cantly dependent on tick’s stage (χ2=23.6, p<0.00001) but not on locality (χ2=9.8, p=0.082). A signifi cant correlation was found between the presence of A. phagocytophilum 16S rRNA gene in I. ricinus female ticks from the particular forest districts and the serologic response to A. phagocytophilum of forestry workers employed in the same districts (p<0.05). No signifi cant correlation was found between the presence of A. phagocytophilum ankA gene in I. ricinus ticks and serologic response of exposed workers. In conclusion, detection of A. phagocytophilum infection in ticks by PCR with the use of EHR521/EHR747 primers detecting 16S rRNA gene is signifi cantly more sensitive compared to LA6/LA1 primers detecting ankA gene.

Existing research for using the protective antigen (PA) of Bacillus anthracis as a vaccine component shows that protection against anthrax may be obtained using fragments of this protein. The aim of the research is to check whether the selected protein fragment of the protective antigen (domain 4) encoded by an appropriate nucleotide sequence of gene pag of B. anthracis, was expressed in the bacterial system of E. coli. In order to examine the selected sequence of the pag gene, a PCR reaction and a highly effective TOPO cloning strategy were used, followed by purification of the recombinant proteins and their detection by a western-blot method. In the planning of the PA4 antigen expression a higher level of effectiveness in production of small protein – domain 4 – was anticipated. As a result, the 139 amino acids protein fragment of B. anthracis PA (domain 4) was isolated. The research may have found the basis for in vivo research aimed at finding potential anthrax vaccine components.

Opis:
Andersen-Tawil Syndrome (ATS) is a rare genetic disorder inherited in an autosomal dominant pattern caused by mutations in the KCNJ2 gene encoding Kir2.1 protein forming potassium ion channel, leading to disruption of cardiac and skeletal muscle repolarisation. Clinical symptoms include periodic paralysis, ventricular arrhythmia associated with QT prolongation and typical skeletal and facial dysmorphic features. The aim of the study was to present characteristic features of the rare Andersen-Tawil syndrome (ATS) within the face and oral cavity of a 9-year-old boy. The patient was diagnosed with Andersen-Tawil syndrome (OMIM#170390) at the age of 8 due to the positive family history, typical dysmorphic features, and the presence of mutation in the KCNJ2 gene confirmed by genetic testing. Typical manifestations of ATS were diagnosed: cardiac arrhythmia, short stature, scoliosis and clinodactyly. Clinical examination revealed typical facial dysmorphic features of ATS: broad forehead, triangular shape of the face, hypertelorism, microstomia, low-set ears, and mandibular retrognathism. Intraoral examination revealed: high-arched palate, crowding in the dental arches, hypomineralisation of enamel and high incidence of dental caries. Dental age assessment by Demirijan pointed to delayed development of permanent dentition. Cephalometric analysis revealed skeletal class II with high angle vertical jaws relation. Diagnosis of ATS requires high index of suspicion because of a great variability in the clinical manifestation of the syndrome. The subtle nature of the dysmorphic features often delays the diagnosis of this syndrome, and its potentially lethal cardiac arrhythmia remaining undetected.

Introduction. Currently, nearly 23,000 cases of lung cancer are diagnosed in Poland annually, of which 5% are cases with rearrangements in the ALK gene. In recent years, tremendous progress has been made in understanding the genetic makeup of this type of cancer, which has enabled the use of new therapies, in particular, molecularly targeted drugs. Crizotinib is the first oral small molecule inhibitor of ALK, MET and ROS1 receptor tyrosine Kinases approved by the European Medicines Agency(EMA). Case report. The paper presents the case of a 62-year-old patient diagnosed with non-small cell lung cancer with rearrangement in the ALK gene in stage IV of the disease. The patient was qualified for treatment with crizotinib under the B6 drug programme. Treatment started in May 2019. During treatment, assessment was made at 3 control points, where the first and second showed a partial response according to the RECIST 1.1 scale; in the next assessment, the response was maintained in the form of disease stabilization.

Opis:
Q fever is an infectious disease of humans and animals caused by Gram-negative coccobacillus Coxiella burnetii, belonging to the Legionellales order, Coxiellaceae family. The presented study compares selected features of the bacteria genome, including chromosome and plasmids QpH1, QpRS, QpDG and QpDV. The pathomechanism of infection – starting from internalization of the bacteria to its release from infected cell are thoroughly described. The drugs of choice for the treatment of acute Q fever are tetracyclines, macrolides and quinolones. Some other antimicrobials are also active against C. burnetii, namely, telitromycines and tigecyclines (glicylcycline). Q-VAX vaccine induces strong and long-term immunity in humans. Coxevac vaccine for goat and sheep can reduce the number of infections and abortions, as well as decrease the environmental transmission of the pathogen. Using the microarrays technique, about 50 proteins has been identified which could be used in the future for the production of vaccine against Q fever. The routine method of C. burnetii culture is proliferation within cell lines; however, an artificial culture medium has recently been developed. The growth of bacteria in a reduced oxygen (2.5%) atmosphere was obtained after just 6 days. In serology, using the IF method as positive titers, the IgM antibody level >1:64 and IgG antibody level >1:256 (against II phase antigens) has been considered. In molecular diagnostics of C. burnetii infection, the most frequently used method is PCR and its modifications; namely, nested PCR and real time PCR which detect target sequences, such as htpAB and IS1111, chromosome genes (com1), genes specific for different types of plasmids and transposase genes. Although Q fever was diagnosed in Poland in 1956, the data about the occurrence of the disease are incomplete. Comprehensive studies on the current status of Q fever in Poland, with special focus on pathogen reservoirs and vectors, the sources of infection and molecular characteristics of bacteria should be conducted.

Opis:
Introduction and objective. According to the cancer epidemiology databases, cancer is the second leading cause of death in developing countries. Moreover, the WHO predicts a continuing increase in the incidence of cancer, extending this trend well into the next several decades. Hence, it seems obvious that the prediction of cancer susceptibility and early diagnosis is an important goal for modern biomedical sciences. The aim of this study is to clarify the value of chromosomal damage, capacity for the repair of double-strand breaks (DSBs), polymorphisms in DNA repair genes, and apoptosis as prognostic markers for prostate and cervical cancer. Materials and methods. 30 prostate cancer patients and 30 cervical cancer patients were enrolled into the study. In addition, 30 healthy female donors and 30 healthy male donors served as controls. The following endpoints were investigated: frequency of micronuclei, gamma-H2AX fluorescence, XRCC1 194C>T, XRCC1 399G>A, XRCC3 IVS5–14 A>G, OGG1 326 Ser>Cys polymorphisms and apoptosis. Results. Among all tested factors, only the homozygous variant (Arg/Arg) in XRCC1 (399 Arg/Gln) was strongly associated with prostate cancer risk, and only a low apoptotic response was connected with cervical cancer risk. The presented study confirmed a positive association between the frequency of MN and increased prostate and cervical cancer risk. However, such a biomarker is not cancer specific. In addition, the information gained by analyzing the gamma-H2AX fluorescence, as well apoptosis, had no value for predicting the risk of prostate and cervical cancers. Conclusions. The final conclusion of the study is that cancer susceptibility is a complex phenotype not readily detectable in relatively small studies by functional assays or analysis of SNP in few, selected genes.
