Yeast Killer Toxin-Like Candidacidal Ab6 Antibodies Elicited through the Manipulation of the Idiotypic Cascade

2014

A mouse anti-anti-anti-idiotypic (Id) IgM monoclonal antibody (mAb K20, Ab4), functionally mimicking a Wyckerhamomyces anomalus (Pichia anomala) killer toxin (KT) characterized by fungicidal activity against yeasts presenting specific cell wall receptors (KTR) mainly constituted by β-1,3-glucan, was produced from animals presenting anti-KT Abs (Ab3) following immunization with a rat IgM anti-Id KT-like mAb (mAb K10, Ab2). MAb K10 was produced by immunization with a KT-neutralizing mAb (mAb KT4, Ab1) bearing the internal image of KTR. MAb K20, likewise mAb K10, proved to be fungicidal in vitro against KT-sensitive Candida albicans cells, an activity neutralized by mAb KT4, and was capable of…

A female-produced short-range sex pheromone in the egg parasitoid Trissolcus brochymenae

2012

The potential for short-range sex pheromone communication by the egg parasitoid wasp Trissolcus brochymenae (Hymenoptera: Platygastridae) was investigated in closed arena bioassays. Males of this parasitoid showed more antennal drumming and more frequent mounting behaviour on 1- to 2-d-old virgin females compared with 8-d-old virgin females. Male copulation attempts were fewer with previously mated females than with virgin females. Males courted and made copulation attempts with 1- to 2-d-old female cadavers, but not with male cadavers or with female cadavers rinsed in organic solvents of different polarities. Male attraction to female cadavers was re-established by treating cadavers with a…

Breeding Tubercles, Papillomatosis and Dominance Behaviour of Male Roach (Rutilus rutilus) During the Spawning Period

2004

We studied the relationship between the breeding tubercle ornamentation (i.e. skin roughness) and male pre-spawning dominance and courtship behaviour in roach (Rutilus rutilus) within an experimental laboratory system. Sexually mature fish were caught during their migration to their spawning pond and their behaviours were studied in an artificial spawning arena. Males behaved naturally both in terms of male–male interactions and attempts to achieve spawnings. Males having many, large breeding tubercles (i.e. rough skin) were significantly more often dominant in our dyadic trials than those with smooth skin. The dominant male in the trial exhibited a more active courtship behaviour than its …

ANALYSIS OF SERUM BIOMARKERS IN YOUNG SOCCER PLAYERS BEFORE AND AFTER A TWO-WEEK PRECOMPETITIVE TRAINING

Anthropometry and body composition of young soccer players

2022

Background: Body composition and other anthropometric measurements are important factors influencing the overall performance of an athlete. Together with motor coordination, physical fitness, physical, functional, and psychosocial conditions, as well as learned technique and tactics, a player's sports potential and probability of success can be determined. Aim of the study: Our study aimed to describe anthropometric variables and body composition of young soccer players of various ages. Materials and methods: A cross-sectional study was carried out among 61 young soccer players in the under-15, under-16, and under-19 categories. We used a bioimpedance analyzer to measure the following indic…

Assessment of selected body composition parameters and nutritional habits of American football players in Poland: a prospective and observational stu…

2021

Introduction: American football is becoming a more and more popular sport in Poland. People practicing this sport have specific nutritional needs. A balanced and rational diet is very important in the process of training an athlete. Not only composition of the body, but also the proper diet is important of the results achieved, deciding on the athlete’s success or failure. The aim of the study is to assess the body composition and nutritional behavior of American football players. Materials and methods: The study was conducted among 46 participants from the American football club ‘Towers Opole’. They were split into 2 groups, senior (n = 31) and junior (n = 15). The following measurements w…

Sexually selected traits evolve positive allometry when some matings occur irrespective of the trait

2014

Positive allometry of secondary sexual traits (whereby larger individuals have disproportionally larger traits than smaller individuals) has been called one of the most pervasive and poorly understood regularities in the study of animal form and function. Its widespread occurrence is in contrast with theoretical predictions that it should evolve only under rather special circumstances. Using a combination of mathematical modeling and simulations, here we show that positive allometry is predicted to evolve under much broader conditions than previously recognized. This result hinges on the assumption that mating success is not necessarily zero for males with the lowest trait values: for examp…

Mid-region PTHrP and gene expression of MDA-MB231 breast cancer cells

2007

Type V collagen is known to be over-deposited in the stroma of ductal infiltrating carcinomas of the breast. When used as a substrate, type V collagen restrains growth and invasion, and affects gene expression of 8701-BC ductal infiltrating carcinomas cells. Here we supplement existing data by demonstrating type V collagen dependent upregulation of capn2 gene expression in 8701-BC cells through differential display-PCR and Western blot assays. Furthermore, we suggest that our data obtained by centrifugal sedimentation and electrophoresis strongly suggest a correlation between calpain overproduction and DNA fragmentation, since the incubation with calpain inhibitor partly reverts the latter.

Lessons Learned Using Theory of Mind Methods to Investigate User Social Awareness in Virtual Role-Play

2009

Theory of mind (ToM) methods were used to investigate children’s interpretations of the social and emotional states of synthetic pedagogical characters, focusing on children’s cognitive and affective empathic responses to characters in bullying scenarios and their social awareness and understanding of the characters’ situations. Although cognitive approaches typically do not consider user social awareness and emotional understanding and their roles in interaction, this is critical for our research on empathic engagement. We present a novel approach focusing on story and character comprehension using concepts from ToM methods to understand children’s interpretations of characters within virt…
