In Vitro Activity of Rifampicin Combined with Daptomycin or Tigecycline on Staphylococcus haemolyticus Biofilms
Aeromonas spp.-mediated cell-contact cytotoxicity is associated with the presence of type III secretion system
In the study we examined the production of cytotonic and cytotoxic toxins and the presence of a type III secretion system (TTSS) in 64 Aeromonas spp. strains isolated from fecal specimens of patients with gastroenteritis. We observed that contact of the bacteria with host epithelial cells is a prerequisite for their cytotoxicity at 3 h incubation. Cell-contact cytotoxic activity of the strains was strongly associated with the presence of the TTSS. Culture supernatants of the strains induced low cytotoxicity effects at the same time of incubation. Cell-free supernatants of 61 (95%) isolates expressed cytotoxic activity which caused the destruction of HEp-2 cells at 24 h. Moreover, 44% strains were cytotonic towards CHO cells and 46% of strains invaded epithelial cells

Sex doll ownership: an agenda for research
Purpose of review: The topic of sex doll ownership is becoming an increasingly discussed issue from both a social and legal perspective. This review aims to examine the veracity of the existing psychological, sexological, and legal literature in relation to doll ownership.
Recent findings: Strong views exist across the spectrum of potential socio-legal positions on sex doll ownership. However, there is an almost total lack of empirical analyses of the psychological characteristics or behavioral implications of doll ownership. As such, existing arguments appear to represent the philosophical positions of those scholars expressing them, rather than being rooted in any objective evidence base.
Summary: Despite an absence of empirical data on the characteristics and subsequent effects of doll ownership, discussions about the ethical and legal status of doll ownership continue. This highlights a real and urgent need for a coherent research agenda to be advanced in this area of work

Completely uniformly distributed sequences as pseudorandom number generators
W pracy zauważony jest problem komputerowej implementacji ciągów w pełni rozłożonych (CUD). W części ogólnej pracy przedstawiono dzesięć przykładów ciągów CUD. W części szczegółowej przedstawiono komputerowe implementacje ciągów Straczenki i Korobowa. Na skonstruowanych generatorach przeprowadzono kilka testów.The paper presents the problem of computer implementation of completely uniformly distributed (CUD) sequences. In the first part of the paper a few examples of CUD se-quences are presented. In the second part the computer implementations of the Korobow and Starczenko sequences are presented. Several tests are performed on the constructed generators
