Ocena jednorodności zanieczyszczenia kory drzew liściastych metalami ciężkimi
2018
Celem badań była ocena jednorodności zanieczyszczenia metalami ciężkimi (Ni, Cu, Zn, Cd i Pb) kory drzew liściastych pobranej z lasu mieszanego na terenie gminy Ozimek (województwo opolskie). W ramach biomonitoringu pasywnego pobrano próbki kory z trzech gatunków drzew liściastych: z brzozy brodawkowatej (Betula pendula Roth.), buka zwyczajnego (Fagus sylvatica L.) oraz z dębu szypułkowego (Quercus robur L.). Metale ciężkie oznaczono za pomocą absorpcyjnej spektrometrii atomowej (AAS). Na podstawie przeprowadzonych badań można jednoznacznie stwierdzić, że kora drzew wykorzystanych do badań różni się pod względem stężeń metali ciężkich. Największe średnie zawartości Cu, Zn, Cd i Pb występują…
SARS-CoV-2 RNA and antibody detection in human milk from a prospective multicenter study in Spain
2021
Background During the COVID-19 pandemic in 2020, breastfeeding in women positive for SARS-CoV-2 was compromised due to contradictory data regarding potential viral transmission. However, growing evidence confirms the relevant role of breast milk in providing passive immunity by generating and transmitting specific antibodies against the virus. Thus, our study aimed to develop and validate a specific protocol to detect SARS-CoV-2 in breast milk matrix as well as to determine the impact of maternal SARS-CoV-2 infection on presence, concentration, and persistence of specific SARS-CoV-2 antibodies. Study design/Methods A prospective multicenter longitudinal study in Spain was carried out from A…
Biomonitoring pasywny terenów leśnych w gminie Twardogóra
2016
Celem przeprowadzonych badań była ocena poziomu zanieczyszczenia wybranymi metalami ciężkimi: Zn, Ni, Cd i Pb terenów leśnych gminy Twardogóra. Miasto Twardogóra położone jest w północno-wschodniej części województwa dolnośląskiego, lasy stanowią 44% całej powierzchni gminy. Porosty Hypogymnia physodes oraz mchy Pleurozium schreberi pobrane zostały z 32 miejsc zlokalizowanych w pobliżu wsi Gola, Goszcz, Grabowno Wielkie oraz Sosnówka. Wybrane metale ciężkie (Ni, Zn, Cd i Pb) oznaczono metodą absorpcyjnej spektroskopii atomowej. Wyniki badań zinterpretowano, wykorzystując m.in. współczynnik porównawczy CF, będący różnicą w stężeniach analitu zakumulowanego w porostach i w mchach, odniesioną …
Exploring the Anatomy of Franchising: A Cross-National Examination of US and Finnish Franchise Contract Provisions
2004
The present study focuses on describing and comparing the provisions of the franchise contracts and pre-sale disclosures to prospective franchisees in the USA and Finland. A fact that makes the investigation especially interesting is that no franchising specific legislation exists in Finland. Whereas in the USA franchisors are by a directive of the Federal Trade Commission required to publicly disclose key information on their franchise systems. The information is of paramount importance for potential franchisees who need to analyze franchise offering(s) before their buying decision. Two separate samples were developed for the study. The member franchisors of the International Franchise Ass…

Effects of Passive Leadership in the Digital Age
2021
Organizations must adapt to the trend of digitalization. Nowadays, social media engagement editors play an increasingly crucial role for organizational growth and prosperity in the digital age. Engagement editors are usually tasked to perform the functions of marketing, content production, and data analysis. They have to manage online communities on behalf of the organization, and encounter online audiences' frequent toxic and aggressive behaviors. Engagement editors thus are prone to emotional stress. Substantial literature has examined the influence of leadership style on employee performance. However, passive leadership is rarely studied. This research investigates (1) whether passive le…
Role of P‐glycoprotein‐mediated secretion in absorptive drug permeabiity: An approach using passive membrane permeability and affinity to P‐glycoprot…
1999
Abstract It has been shown in vivo and in vitro that P‐glycoprotein (P‐gp) may be able to influence the permeability of its substrates across biological membranes. However, the quantitative contribution of the secretion process mediated by P‐gp on the overall permeability of membranes has not been determined yet. In particular, observations need to be clarified in which substrates showing high affinity to P‐glycoprotein, e.g., verapamil, apparently do not seem to be greatly influenced by P‐gp in their permeability and consequently also with respect to their extent of GI‐absorption after oral administration, whereas weaker substrates of P‐gp, e.g., talinolol, have clearly shown P‐gp‐related …
La détermination passive et quelques thématisations particulières en anglais médical
1997
À partir d’exemples caractéristiques issus d’un corpus de 2 115 structures passives tirées de la revue britannique The Lancet, j’ai réalisé une classification originale de ces diathèses passives en trois grandes catégories, à savoir la détermination passive simple, la détermination passive complexe et la détermination passive tronquée. Après avoir précisé en quoi ces opérations de détermination correspondaient à une stratégie énonciative particulière — qu’elle soit réfléchie ou spontanée — mise en œuvre par les médecins, j’ai analysé quelques formes extrêmes, ou déterminations particulières, notamment celles présentées sous la forme d’adjectifs composés. Thanks to 2,115 passive structures c…
Reproducibility of Rolandic beta rhythm modulation in MEG and EEG
2022
The Rolandic beta rhythm, at ∼20 Hz, is generated in the somatosensory and motor cortices and is modulated by motor activity and sensory stimuli, causing a short lasting suppression that is followed by a rebound of the beta rhythm. The rebound reflects inhibitory changes in the primary sensorimotor (SMI) cortex, and thus it has been used as a biomarker to follow the recovery of patients with acute stroke. The longitudinal stability of beta rhythm modulation is a prerequisite for its use in long-term follow-ups. We quantified the reproducibility of beta rhythm modulation in healthy subjects in a 1-year-longitudinal study both for MEG and EEG at T0, 1 month (T1-month, n = 8) and 1 year (T1-ye…
