    Stem cells for skeletal muscle originate from dermomyotome of the embryo. The early marker of these cells is expression of both transcription factors Pax3 and Pax7 (Pax3+/Pax7+ cells). The skeletal muscles in the adult organism have a remarkable ability to regenerate. Skeletal muscle damage induces degenerative phase, followed by activation of inflammatory and satellite cells. The satellite cells are quiescent myogenic precursor cells located between the basal membrane and the sarcolemma of myofiber and they are characterized by Pax7 expression. Activation of the satellite cells is regulated by muscle growth and chemokines. Apart from the satellite cells, a population of adult stem cells (muscle side population--mSP) exists in the skeletal muscles. Moreover, the cells trafficking from different tissues may be involved in the regeneration of damaged muscle. Trafficking of cells in the process of damaged muscle regeneration may be traced in the SCID mice

    Artyku艂 przedstawia problematyk臋 pos艂ugiwania si臋 zobiektywizowanym sposobem oceny rozmiaru krzywdy przy ustalaniu zado艣膰uczynienia pieni臋偶nego na rzecz poszkodowanego pacjenta. Opracowanie mo偶na podzieli膰 na dwie cz臋艣ci. W pierwszej om贸wiono sytuacj臋 faktyczn膮 i prawn膮 osoby b臋d膮cej podmiotem 艣wiadcze艅 zdrowotnych w kontek艣cie ochrony jej d贸br osobistych. W tej cz臋艣ci przedstawione zosta艂y r贸wnie偶 podstawy prawne kompensacji krzywdy wynikaj膮cej z wadliwo艣ci udzielania 艣wiadcze艅 zdrowotnych. W drugiej cz臋艣ci ukazano znaczenie zobiektywizowanego sposobu oceny rozmiaru krzywdy na przyk艂adzie pacjent贸w poszkodowanych w okresie prenatalnym oraz pozostaj膮cych w 艣pi膮czce m贸zgowejThe article presents the issue of using objective methods to assess the scale of harm in the process of establishing financial compensation for patients injured in the course of treatment. The study can be divided into two parts. The first one discusses the factual and legal situation of a person who is a healthcare beneficiary in the context of the protection of his or her personality rights. This section also presents the legal grounds for compensatory damages for providing defective healthcare services. The second part shows the significance of the objective method of assessing the extent of harm inflicted, as exemplified by patients injured during a prenatal period and patients in the cerebral coma

    Newcastle disease virus (NDV), member of the Paramyxoviridae family and avian influenza virus (AIV), member of the Orthomyxoviridae family, are two main avian pathogens causing serious economic problems in poultry health. Both are enveloped, single-stranded, negative-sense RNA viruses and cause similar symptoms, ranging from sub-clinical infections to severe diseases, including decrease in egg production, acute respiratory syndrome, and high mortality. Similar symptoms hinder the differentiation of infection with the two viruses by standard veterinary procedures like clinical examination or necropsy. To overcome this problem, we have developed a new duplex real-time PCR assay for the detection and differentiation of these two viruses. Eighteen NDV strains, fourteen AIV strains, and twelve other (negative control) strains viruses were isolated from allantoic fluids of specific pathogen-free (SPF), embryonated eggs. Four-weeks-old SPF chickens were co-infected with both viruses (NDV - LaSota and AIV - H7N1). Swabs from cloaca and trachea were collected and examined. The results obtained in this study show that by using duplex real-time PCR, it was possible to detect and distinguish both viruses within less than three hours and with high sensitivity, even in case a bird was co-infected. Additionally, the results show the applicability of the real-time PCR assay in laboratory practice for the identification and differentiation of Newcastle disease and influenza A viruses in birds

    BACKGROUND: The study was undertaken to develop a potential new markers for distinguishing minimal change nephrotic syndrome (MCNS) and focal segmental glomerulosclerosis (FSGS) in children. We hypothesized that matrix metalloproteinase-9/neutrophil gelatinase-associated lipocalin (MMP-9/NGAL) is a better marker of focal sclerosis in the glomerulus then matrix metalloproteinase-9/tissue inhibitor of metalloproteinase-1 (MMP-9/TIMP-1) and matrix metalloproteinase-2/tissue inhibitor of metalloproteinase-2 MMP2/TIMP-2

    Wykorzystanie akcelerometr贸w jako metody poprawy przestrzegania zalece艅 dotycz膮cych aktywno艣ci fizycznej w leczeniu oty艂o艣ci u dzieci

    Background. The evidence has showed that increasing physical activity is a particularly important element not only in prevention but also in the treatment of obesity. This study aimed to examine whether the use of accelerometers for monitoring physical activity is a sufficient motivator to adhere the recommended level of physical activity. Material and methods. The prospective study involved 44 obese children and adolescents aged 5 to 17 who were registered with the Pediatric Nephrology Department at the Medical University of Bialystok, Poland. Participants had to wear a device for at least 12 hours per day for 56 consecutive days. Anthropometric measurements were made at the beginning of the study and after eight weeks of physical activity monitoring. Results. The presented study results far exceeded the recommended amount of the average physical activity energy expenditure of young patients in the first two weeks. In the following weeks, the amount of daily energy expenditure gradually diminished, but finally, the average BMI Z-score was reduced from 2.80卤0.64 at baseline to 2.48卤0.27 at the end of the study (p<0.0147). Conclusions. The study demonstrates that tracking of physical activity may be an essential factor to improve compliance with physical activity recommendations.Wprowadzenie. Wyniki bada艅 wykazuj膮, 偶e zwi臋kszenie aktywno艣ci fizycznej jest szczeg贸lnie wa偶nym elementem nie tylko profilaktyki, ale tak偶e leczenia oty艂o艣ci. Niniejsze badanie mia艂o na celu stwierdzenie, czy wykorzystanie akcelerometr贸w do monitorowania aktywno艣ci fizycznej stanowi wystarczaj膮cy czynnik motywuj膮cy do przestrzegania zalecanego poziomu aktywno艣ci fizycznej. Materia艂 i metody. W prospektywnym badaniu wzi臋艂o udzia艂 44 oty艂ych dzieci i nastolatk贸w w wieku od 5 do 17 lat, kt贸rzy zostali zarejestrowani w Klinice Pediatrii i Nefrologii Uniwersytetu Medycznego w Bia艂ymstoku. Uczestnicy musieli nosi膰 urz膮dzenie przez co najmniej 12 godzin dziennie przez 56 kolejnych dni. Pomiary antropometryczne wykonano na pocz膮tku badania i po o艣miu tygodniach monitorowania aktywno艣ci fizycznej. Wyniki. Wyniki badania wykaza艂y znaczne przekroczenie zalecanej ilo艣ci 艣redniego wydatku energetycznego zwi膮zanego z aktywno艣ci膮 fizyczn膮 m艂odych pacjent贸w w ci膮gu pierwszych dw贸ch tygodni. W kolejnych tygodniach ilo艣膰 dziennego wydatku energetycznego stopniowo mala艂a, ale ostatecznie 艣redni Z-score BMI zosta艂 zmniejszony z 2,80卤0,64 na pocz膮tku badania do 2,48卤0,27 na ko艅cu badania (p< 0,0147). Wnioski. Badanie pokazuje, 偶e monitorowanie aktywno艣ci fizycznej mo偶e by膰 istotnym czynnikiem poprawiaj膮cym przestrzeganie zalece艅 dotycz膮cych aktywno艣ci fizycznej
