Parametric study of fluidization conditions of bed sediments in the hyporheic zone

Marek Marciniak, Mariusz Kaczmarek, Magdalena Matusiak, Anna Szczucińska

Hydrological Processes > 36 > 8 > n/a - n/a

The phenomenon of fluidization of the bed sediment of the hyporheic zone involves the production of dynamic suspension of solid particles in a stream of water flowing in the direction opposite to gravity. Fluidization may be permanent; then, it becomes a spring or a headwater zone, where groundwater discharge rate is almost unchanged within an entire hydrological year. But it can also occur periodically,...

Mariusz Kaczmarek, Joanna Nowak, Waldemar L. Olszewski, Marzanna Zaleska

International Journal for Numerical Methods in Biomedical Engineering > 38 > 1 > n/a - n/a

A two‐chamber inflation‐deflation test was recently proposed as a diagnostic method to determine parameters of the intermittent pneumatic compression used as an effective therapeutic modality for lymphedematous limbs. It is crucial that the recorded trends for residual tissue deformations are understood in terms of specific properties of subcutaneous tissue and skin to support diagnostic process....

Jan Żeromski, Mariusz Kaczmarek, Maciej Boruczkowski, Agata Kierepa, more

Archivum Immunologiae et Therapiae Experimentalis > 2019 > 67 > 3 > 133-141

Pattern recognition receptors (PRRs) are members of innate immunity, playing pivotal role in several immunological reactions. They are known to act as a bridge between innate and adaptive immunity. They are expressed on several normal cell types but have been shown with increasing frequency on/in tumor cells. Significance of this phenomenon is largely unknown, but it has been shown by several authors...

Monika Okońska, Marek Marciniak, Joanna Zembrzuska, Mariusz Kaczmarek

Geologos > 2019 > Vol. 25, No. 3 > 213--223

At present, concentrations of pharmaceuticals in surface and ground waters are low; however, even low concentrations of certain substances may prove very harmful. One of such pharmaceutical drugs is diclofenac, a popular non-steroidal anti-inflammatory drug (NSAID). For this reason, it is important to determine its mobility in groundwater and to estimate parameters of migration. Authors conducted...

Marek Marciniak, Magdalena Matusiak, Anna Szczucińska, Mariusz Kaczmarek

Biuletyn Państwowego Instytutu Geologicznego > 2019 > nr 476, Hydrogeologia z. 17 > 79--85

Strefa hyporeiczna jest obszarem współdziałania wód powierzchniowych i podziemnych. Warunki w jakich funkcjonuje ta strefa mają ważne znacznie dla organizmów roślinnych i zwierzęcych tam bytujących, ale także dla wymiany wód, ich składu chemicznego oraz reakcji zlewni na opady. W warunkach drenażu wód podziemnych przez wody powierzchniowe może dochodzić do fluidyzacji, czyli upłynnienia osadów dennych...

Concentrations of SP-A and HSP70 are associated with polarization of macrophages in pleural effusions of non-small cell lung cancer

Mariusz Kaczmarek, Malgorzata Lagiedo, Agnieszka Masztalerz, Magdalena Kozlowska, more

Immunobiology > 2018 > 223 > 2 > 200-209

Damage-associated molecular pattern (DAMP) molecules can initiate an immune response through Toll-like receptors (TLRs). DAMPs are released from cells as a response to the extracellular danger and can be by-products of tissue damage. In cancer microenvironment necrotic cells release debris which has potency to become DAMPs. Non-small cell lung cancer (NSCLC) is often accompanied by pleural effusion...

A method for the estimation of dual transmissivities from slug tests

Filip Wolny, Marek Marciniak, Mariusz Kaczmarek

Hydrogeology Journal > 2018 > 26 > 2 > 407-416

Aquifer homogeneity is usually assumed when interpreting the results of pumping and slug tests, although aquifers are essentially heterogeneous. The aim of this study is to present a method of determining the transmissivities of dual-permeability water-bearing formations based on slug tests such as the pressure-induced permeability test. A bi-exponential rate-of-rise curve is typically observed during...

Medical Microbiology and Immunology > 2018 > 207 > 1 > 55-63

Treatment with pegylated interferon-α and ribavirin (PEG–IFN/RBV) is the only choice for chronic hepatitis C (CHC) in children. Natural killer (NK) cells were described to play a vital role in CHC. The aim of this study was to analyze the expression of peripheral blood NK cell receptors in their relation to PEG–IFN/RBV treatment response. Study included 26 children with CHC—13 boys, age range 13.42...
