Abstract Bees are often exposed to pesticides affecting physiological functions and molecular mechanisms. Studies showed a potential link between altered expression of energy metabolism related transcripts and increased homing flight time of foragers exposed to pesticides. In this study, we investigated the effects of thiamethoxam and pyraclostrobin on longevity, flight behavior, and expression of transcripts involved in endocrine regulation (hbg-3, buffy, vitellogenin) and energy metabolism (cox5a, cox5b, cox17) using radio frequency identification (RFID) technology and quantitative polymeras

INTRODUCTION. The double chin is an excessive accumulation of fat in the pre- and post-platysma that can manifest in various forms and sizes. Thin individuals might manifest a double chin, similar to those who are afflicted by obesity. It may result in a reduction in the definition of the mandible and give the perception of obesity or aging. AIM. To evaluate any effect of High-Intensity Focused Ultrasound (HIFU) on sleep quality measures in obese women with a double chin. MATERIALS AND METHODS. Typically, 60 women aged 35–50 years were selected from AL Qasr-Alaini Hospital and were equally div

This study evaluated the effect of vacuum and modified atmosphere (40% CO2+60% N2, MA) packaging on the chemical composition, physicochemical properties and sensory attributes of chill-stored meat from 10 fallow deer (Dama dama) bucks at 17 to 18 months of age. The animals were hunter-harvested in the forests of north-eastern Poland. During carcass dressing (48 to 54 h post mortem), both musculus longissimus muscles were cut out. Each muscle was divided into seven sections which were allocated to three groups: 0, A, and B. Samples 0 were immediately subjected to laboratory analyses. Samples A

The Yellow-legged Gull (Larus michahellis) is a widespread and opportunistic central-place forager during the breeding season, yet its spatial behavior and habitat use in Adriatic Sea remain poorly understood. Our aim was to investigate their foraging ranges, movement patterns, and habitat selection during the breeding season. In this study, we tracked 45 adult gulls from 9 breeding colonies distributed along the Adriatic coast using high-resolution GPS devices. Most individuals foraged relatively close to their breeding sites, typically within 20–50 km. However, some gulls demonstrated the ca

The aim of this work was to investigate the application of common packaging materials polypropylene (PP) and polystyrene (PS) in the probiotic fresh cheese production packaging. Probiotic and traditional cheeses were produced from milk with standardized milk fat content of 2.3 g/100 g including the application of two cultures (probiotic and traditional). The samples were packed in the PP and PS cups and stored at 4 ºC for 30 days. The observed permeability of gases through the two applied packaging materials was significantly different. Cheese samples were analysed for microbiological properti

Bumble bees are important pollinators of crops and other plants. However, many aspects of their basic biology remain relatively unexplored. For example, one important and unusual natural history feature in bumble bees is the massive size variation seen between workers of the same nest. This size polymorphism may be an adaptation for division of labor, colony economics, or be nonadaptive. It was also suggested that perhaps this variation allows for niche specialization in workers foraging at different temperatures: larger bees might be better suited to forage at cooler temperatures and smaller
