First person – Simona Amodeo
No full textABSTRACT
First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Simona Amodeo is the first author on ‘Characterization of the novel mitochondrial genome replication factor MiRF172 in Trypanosoma brucei’, published in Journal of Cell Science. Simona is a PhD student in the lab of Torsten Ochsenreiter at the Institute of Cell Biology, University of Bern, Switzerland, investigating mitochondrial genome anchoring, replication and inheritance in Trypanosoma brucei.</jats:p
Hysteroscopic removal of a gauze inadvertently retained in uterus for two years following caesarean section
No full textDespite the worldwide accomplishment of manual counting procedures of surgical textiles and instruments, cases of retained (forgotten) surgical items (RSIs) still occur. Gauzes are the most frequently RSIs, accounting for 90% of the cases because they are widely used. Approximately half of the cases occur in the context of general surgery procedures, fol- lowed by gynaecological – obstetrics surgery. The time inter- val between initial surgery, diagnosis and removal of the gauze is clinically relevant, as the morbidity and mortality are reduced if the foreign body is removed immediately after the offending operation. We report on a successful hysteroscopic identification and removal of a gauze inadvertently forgotten in utero two years after a C-Section in a symptomatic woman
Don’t be scared to touch! Effectiveness of a new disinfection technology based on Ag ions & Zeolite: Valerio Peruzzi
No full textBACKGROUND: Disinfection of contact surfaces has become common practice since the two-year Covid-19 pandemic. The transmission of microbial agents has long been the focus of public health and hygiene awareness campaigns. Indeed, the development of new disinfection technologies and approaches is attracting considerable interest in the scientific community. Mixed plastic powders with antimicrobial properties and silver ions that compromise the metabolism of microorganisms could reduce the contamination of the contact surfaces. We aimed to evaluate an inorganic antimicrobial agent (IAA) based on Ag ions and zeolite mixed in a resin. METHODS: This experimental study was carried out at the University of Siena, Italy. Different objects were produced in two versions: i) with an IAA mixed in plastic resin; ii) with a standard plastic mixture. To the eye, the two versions were indistinguishable and were randomly contaminated with the hands of several operators. After the hand contamination, T0, we sampled the objects using RODAC plates at T1 (1h) and T2 (6h), incubating at 36 °C for 48 hours. Comparisons of the biocidal effect were made at T1 and T2. Statistical analysis was carried out with Stata. RESULTS: The mean level of contamination of the objects made with standard plastic were, respectively 50 CFU (SD 36.5) at T1 and 20 CFU (SD 13.6) at T2. In comparison, the objects made with IAA resin showed a mean level of contamination of 10 CFU (SD 5.9) at T1 and 6 CFU (SD3.6) at T2. The objects made with IAA resin have shown a mean percentage reduction of contamination of 79.5% at T1 and 78.3% at T2. CONCLUSIONS: IAA resin reduced contamination on objects that came into contact with hands. Antimicrobial plastic blends, are a valuable aid in counteracting the spread of infection related to contact with surfaces and fomites. The public health system could support and raise awareness for using these innovative materials for everyday applications and in healthcare facilities. KEY MESSAGES: • Inorganic antimicrobial agent based on Ag ions and Zeolite mixed in a resin are efficient in reducing the contamination on different items in a real-life context. • Public health system have to support and sensitize to production with inorganic materials with proven antimicrobial properties
Lo stigma anti-transgender da una prospettiva ecologico-sociale: Effetti sulla salute psico-fisica e strategie di intervento
No full textThe present study offers an overview on stigma against transgender people, analyzing its effects on physical and psychological well-being. We adopted a socio-ecological perspective, according to which antitransgender stigma may manifest at different levels: along the environment-individual spectrum, stigma may occur at the institutional, interpersonal and individual level. All these typologies make transgender people a very vulnerable group, at risk for several health problems. Authors will finally overview some specific psycho-social interventions aimed at reducing stress, by matching each level of stigma with internationally well-established good practices

VUV resonance radiation trapping in an effusive He beam
No full textWe have characterized experimentally the trapping of resonance radiation in an effusive He beam produced by a needle injector. In order to take into account the influence of secondary effects, such as collisions, on the trapping process, the measurements were carried out by investigating the line intensity dependence on the atomic density of transitions 3(1)P --> 2(1)S (lambda = 501.6 nm), and 3(1)D --> 2(1)P (lambda = 667.8 nm) in the visible and 3(1)P --> 1(1)S (lambda = 53.7 nm) and 2(1)P --> 1(1)S (lambda = 58.4 nm) in the vacuum ultraviolet region of the helium spectrum. The comparison between visible and vacuum ultraviolet spectra allowed us to characterize the excitation process and to evaluate the contribution of collisional effects. We have calculated the escape factor, g, as a function of the atomic density and of the distance from the needle injector, i.e. along the beam path. The results were also compared with the Holstein and Phelps approach describing the trapping process in terms of an effective radius, rho. Our results show that in the case of an effusive beam, the effective radius is of the order of the effusive beam radius, namely rho(b) = 0.70 +/- 0.04 mm. RI Berardi, Vincenzo/H-4550-201
