Transformation of Forest Vegetation After 40 Years of Protection in the Tomczyce Nature Reserve (Central Poland)

The Tomczyce nature reserve is characterized by a degenerated forest vegetation. We assume that the regeneration process was possible to launch after the establishment of the nature reserve in 1968. The vegetation of the Tomczyce forest complex was characterized for the first time by Jakubowska-Gabara (1976) whose studies were taken as a basis of our research. The phytocenoses after 40. years of protection have a greater participation of species with higher trophic and moisture requirements. The regeneration process in communities with pine trees is caused by an expansion of broad-leaved trees and shrubs. Transformation of forest vegetation causes a decrease in cover of thermophilous and heliophilous species. On the other hand, species of oak-hornbeam forests as well as anthropophytes are in expansion. Planning of the protection activities in the nature reserve needs to include these dynamic tendencies of the vegetation

Promotion of healthy nutrition of seafarers

Nutrition disorders arise from various interacting factors: cultural, environmental, genetic, physiological, and psychological. Excessive consumption of highly processed food, sugar, salt, alcohol, and saturated fats is a problem nowadays, and consumption of fish, vegetables, and fruit is insufficient. Overeating and an unbalanced diet are often accompanied by stress and a lack of physical activity. This is intensified by easy access to “comfort food”, “fast food”, and “junk food”. The number of people suffering from overweight and obesity, so-called diseases of civilization, is increasing. Not only is being overweight a risk factor for the development many other metabolic diseases, but it also significantly worsens the quality of life. This also concerns people working at sea. Obesity is favoured by emotional eating disorders (EED), uncontrolled/compulsive eating - binge eating disorders (BED), and night eating disorders (NED). Most frequently, eating is a reaction to stress or boredom. It alleviates tension and improves the mood, also of seafarers

Porównanie sytuacji socjolingwistycznej uczniówszkół polskich z Mościsk, Gródka (Ukraina) oraz Solecznik (Litwa)

The aim of the article is to analyze the sociolinguistic situation of pupils attending Polish schools in Mostyska, Horodok (Ukraine) and Šalčininkai (Lithuania). The com­parison of sociolinguistic data of youth receiving education in the Polish language in Lithuania and Ukraine was based on questionnaire material collected by authors in May 2015. 40 questionnaires have been filled out by pupils of the 7th and 8th grades (14–15 years old) in each town, Šalčininkai and Horodok; in Mostyska, 62 pupils of the 9th–11th grades (15–17 years old) have filled out the questionnaires. The research hypothesis is the following: The sociolinguistic situation of youth attending Polish schools in different countries and participating in various language contacts is similar. The analysis includes declarations of nationality and descent, mother tongue, prestige language and situational usage as well as the knowledge of particular languages.Celem artykułu jest analiza sytuacji socjolingwistycznej uczniów ze szkół pol­skich w Mościskach, Gródku (Ukraina) oraz Solecznikach (Litwa). Porównania da­nych socjolingwistycznych młodzieży pobierającej naukę w języku polskim na Litwie i na Ukrainie dokonano na podstawie materiału ankietowego zebranego przez autorki w maju 2015 roku. W Solecznikach i w Gródku zebrano po 40 ankiet wypełnionych przez uczniów 7–8 klasy (14–15 lat), w Mościskach zaś 62 ankiety zostały wypeł­nione przez uczniów 9–11 klasy (15–17 lat). Analizą objęto odpowiedzi na pytania dotyczące narodowości i pochodzenia badanych, języka ojczystego, prestiżu języko­wego, użycia oraz znajomości języków. Na podstawie porównania danych wysunięto hipotezę badawczą, że sytuacja socjolingwistyczna młodzieży, uczącej się w szkołach polskich w różnych państwach i uczestniczącej w różnych kontaktach językowych, jest podobna

Decomposition of the student’s role as a result of distance learning. First-year students’ narratives about the experiences of entering adulthood during a pandemic

The article will present the functioning of first-year students who started their studies at the University of Zielona Góra in the 2020/21 academic year. At that time, all universities in Poland had e-learning, conducted with the use of appropriate internet tools. It seemed reasonable to ask about the consequences of such a situation for fulfilling the role of a student. Under normal conditions, taking it up is often associated with moving out of the house, taking up additional work, a greater range of independence, i.e. the occurrence of classic markers of adulthood. In a pandemic, this process has not even started. The students stayed in their homes under the care of their parents. We put forward the thesis that remote education has resulted in the decomposition of the classical designations of the role of a student. After the end of the adolescence phase and the closure / expiry of the role of a high school student, there was no transition to the role of a student and to the early adulthood phase to the extent that it would have been in the normal course

Hyper-frontality in an OCD patient – evidence from event-related potentials in a cued GO/NOGO task

Objective The study aimed to evaluate the hyperactivity of the frontal lobes in a patient with obsessive-compulsive disorders. Case description A 21-year-old female met the diagnostic criteria of DSM-5 since her behaviour was characterized by a preoccupations with negative thoughts and by repetitive attempts to decrease or stop those behaviours. Two working hypotheses were tested to find neuromarkers of OCD and anxiety in the patient described. In agreement with the ‘OCD hypothesis’ an increase of the frontal beta activity and an increase of the parietalalpha activity pattern was found. The ‘anxiety’ hypothesis found confirmation in an increased left temporal P1 wave in response to the visual stimuli observed in ERPs. In all three conditions (EO, EC, GO/NOGO task), two characteristics were deviant from the normative average data in EEG spectra. First, an increase of frontal beta activity and the increase of parietal alpha activity was noted. The independent component analysis applied for 700 ms EEG fragments in GO and NOGO conditions revealed a strong activation over the central areas. Conclusions pecific patterns of QEEG and ERPs, the increase of beta activity frontally, and the increase of parietal alpha activity pattern which produce hyper-frontality, might be useful in the diagnosis of an OCD patient. ERPs in a GO/NOGO task can be used in the assessment of functional brain changes in OCD patients

The spread of alien species along the touristic routes of the Słowiński National Park

Touristic routes have a great meaning for the spread of alien species through the protected areas like national parks. The aim of the study was to assess the spread of the chosen species along the different kinds of touristic routes of the Słowiński National Park and asphalt roads lying in the direct vicinity of the Park, in its protective zone. The presence of 108 localities of eight alien species were recorded (Padus serotina, Quercus rubra, Acer negundo, Robinia pseudoacacia from woody species and Conyza canadensis, Impatiens parviflora, Juncus tenuis and Oxalis fontana from herbaceous plants). The localities of the woody plants were found in areas where they were formerly deliberately planted or near routes leading to such areas. All of the analysed woody plants can be the source of ecological threat and should be actively removed. Interestingly, regarding herbaceous plants, the species which according to literature are not a threat to untransformed habitats – Juncus tenuis and Oxalis fontana – were noted quite commonly. Their populations should be monitored. The populations of Impatiens parviflora, classified to the IV class of invasiveness and Conyza canadensis, which can invade sand dunes, should be destroyed as soon as possible till they occupy small areas

Pregnancy-associated breast cancer - diagnosis, treatment and outcomes for women and their offspring

Introduction: Pregnancy-associated breast cancer (PABC) is the most common malignancy in pregnant women with an incidence of 1 in 3-10 thousand pregnancies. It is mostly defined as breast cancer diagnosed during pregnancy or within 1 year postpartum. The number of PABCs is going to raise due to the trend of delaying childbearing. Purpose: This review summarizes data on the occurrence and characteristics of PABC. The analysis comprises diagnosis and proper treatment of BC during pregnancy. Prognosis of women and their offspring are emphasized. Material and methods: The review is based on publications mainly from 2010 to 2019 and 5 articles from 1994-2008 collected on the PubMed.  Results: The sensitivity of breast ultrasonography (USG) in pregnancy is 70-100% and it is considered as safe for the fetus. Staging evaluation in pregnant women consists of chest x-ray, liver USG and non-contrast bone MRI. 71-88% of PABCs are invasive ductal carcinomas. Treatment consists of breast surgery regardless of time and optionally, chemotherapy from the 2nd trimester. Radiotherapy, tamoxifen and trastuzumab are contraindicated in PABC. Therapeutic abortion does not improve oncological outcome. Overall prognosis is similar for both pregnant and non-pregnant patients with similar type and stage of BC. The rate of congenital malformations is 1,3% for both children of PABC patients treated with chemotherapy and born from women without chemotherapeutic treatment. The most frequent obstetrical complication of PABC treatment is preterm delivery. Conclusions: Pregnancy does not impact oncologic outcome, if the treatment is appropriate. PABC patients have survival rates consistent with the stage of disease. Proper treatment of PABC does not increase the risk of congenital malformations and is relatively safe for the fetus. 

Computed tomography evaluation of patent paraumbilical vein and its aneurysm in relation to other portosystemic collateral channels in patients with liver cirrhosis and portal hypertension

Purpose: The aim of the study was to evaluate the relationship between the diameter and aneurysmal dilatation of the paraumbilical vein (PUV) and the presence of portosystemic collateral shunts and their relationship with age and portal vein diameter. Material and methods: The retrospective analysis, performed in the II Department of Radiology, Medical University Hospital in Warsaw, included 126 patients (77 males and 49 females) with patent umbilical vein and signs of portal hypertension due to liver cirrhosis. All patients underwent contrast enhanced abdominal CT. The average age was 54.7 ±12.98. We analysed the number and type of portosystemic collateral channels in respect of age, sex, presence of oesophageal varices, and the diameter of the paraumbilical vein and the portal vein. Results: Our results disclosed statistically significant negative correlation between patient age and diameter of paraumbilical vein, number of portosystemic collateral channels and diameter of portal vein and positive correlation between diameter of paraumbilical vein and diameter of portal vein. A statistically significant difference in diameter of portal vein and number of collateral channels was found in groups with and without oesophageal varices. No significant difference in age and portal vein diameter was found in these groups. Conclusions: Our study showed that younger patients with liver cirrhosis are characterised by wider paraumbilical veins and higher number of portosystemic collateral channels. The presence of oesophageal varices does not correlate with age, sex, diameter of paraumbilical vein, and number of collateral portosystemic channels
