Much attention has been given in the literature to the effects of astrophysical events on human and land-based life. However, little has been discussed on the resilience of life itself. Here we instead explore the statistics of events that completely sterilise an Earth-like planet with planet radii in the range 0.5-1.5R ⊕ and temperatures of ∼300 K, eradicating all forms of life. We consider the relative likelihood of complete global sterilisation events from three astrophysical sources - supernovae, gamma-ray bursts, large asteroid impacts, and passing-by stars...

French Army Health Service provides medical support for armed forces deployed on external missions.In order to ensure the same health care quality in the theatre and in the metropolis, the Military Health Service provides sterilization of reusable medical devices by its own means. Army pharmacists carrying out an on-site mission comes from different domains: medical biology laboratory, research, medical supplies, hospital pharmacy or yet pharmaceutical laboratory for some reservists. Training program for sterilization in isolated military operations areas is therefore necessary in order to ensure knowledge uniformity...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease. Neoadjuvant therapy (NA) with chemotherapy (NAC) and radiotherapy (RT) prior to surgery provides promise. In the absence of prospective data, well annotated clinical data from high-volume units may provide pilot data for randomised trials. METHODS: Medical records from a tertiary hospital in Sydney, Australia, were analysed to identify all patients with resectable or borderline resectable PDAC...

Complications of patellofemoral arthroplasty often occur soon after implantation and, as well as other factors, can be due to the design of the implant or its surgical positioning. A number of studies have previously considered the wear of ultra-high-molecular-weight polyethylene patellae following suboptimal implantation; however, studies have primarily been carried out under a limited number of degrees of freedom. The aim of this study was to develop a protocol to assess the wear of patellae under a malaligned condition in a six-axis patellofemoral joint simulator...

BACKGROUND: During functionality testing and packaging of reusable surgical instruments (RSI) for sterilisation, instruments are frequently touched. Considering the lack of standards relating to hand hygiene frequency and use of gloves in the sterilising service unit packing area, we aimed to determine the effect of hand hygiene and glove use on maintenance of RSI cleanliness. METHODS: Following manual and automated cleaning, Halsted-mosquito forceps were assessed for adenosine triphosphate (ATP), protein and microbial contamination after handling with gloved and ungloved but washed hands utilising an ATP surface swab test, bicinchoninic acid assay, and standard culture plate/broth, respectively...

Raphaela Berto, Jürgen Strutz
Hospital facilities issue numerous risk announcements on corrosion, deformation or premature wearout of medical devices every year. As there is yet little data on the impact of reprocessing on the quality and durability of microsurgical instruments, this paper aims at evaluating the effects of the reprocessing on microsurgical instruments. Material and Methods 22 brand new microsurgical instruments for stapes surgery were being reprocessed 30 times without being used for surgery or other purposes in the interim time...

Pyrazinamide is used in the treatment of tuberculosis(TB) because its sterilising effect against tubercle bacilli allows treatment shortening. It is part of standard treatment for drug-susceptible and drug-resistant TB, and it is being considered as a companion drug in novel regimens. The aim of this analysis was to characterize factors contributing to the variability in exposure and to evaluate drug exposures using alternative doses, thus providing evidence to support revised dosing recommendations for drug-susceptible and multi-drug resistant tuberculosis(MDR-TB)...

Several options have been proposed for eradication of germ cells (GCs) in mammals such as treatment with cytotoxic drugs, irradiation, cold ischemia and hyperthermic treatment. Some of these methods have been also tried in fish but conditions for complete sterilisation of gonads have not been established. Here, we report the production of sterile adult common carp Cyprinus carpio in 10 weeks by the heat and chemical treatments. The cytotoxic drug busulfan (40mg/kg) was intraperitoneally injected into the animals at 2-week intervals (5 doses in total), and they were maintained in water at 38°C between Weeks 1 and 10...

Rainwater, which is used for drinking purposes near Hanoi, Vietnam, was analysed for water quality based on 1.5 years of monitoring data. In total, 23 samples were collected from different points within two rainwater harvesting systems (RWHSs). Most parameters met the standard except micro-organisms. Coliform and Escherichia coli (E. coli) were detected when the rainwater was not treated with ultraviolet (UV) light; however, analysis of rainwater after UV sterilisation showed no trace of micro-organisms. The RWHSs appear to provide drinking water of relatively good quality compared with surface water and groundwater...

Peter Dunne
The possibility of individuals procreating post-transition has long stalked debates on transgender rights. In 1972, Sweden became the first European jurisdiction to formally acknowledge preferred gender. Under the original Swedish law, applicants for gender recognition were explicitly required to prove an incapacity to reproduce-either through natural infertility or through a positive act of sterilisation. Across the Council of Europe, 20 countries continue to enforce a sterilisation requirement. When considering reforms to their current gender recognition rules as recently as 2015, the Polish executive and the Finnish legislature both rejected proposals to remove mandatory infertility provisions...

Only scanty reports are available on endophytic fungal associations in Achyranthes aspera Linn. Hence in this study a total of 504 isolates belonging to ten different species of fungi were isolated from asymptomatic, surface sterilised segments of leaf, stem and root of A. aspera collected from different locations of Kerala, India. Among the isolates ascomycetes were most prevalent. Colonisation rate of fungal endophytes was high in leaf tissue (95%) followed by stem (77.75%) and root segments (33.33%). The most frequent and dominant coloniser of the host plant were Colletotrichum sp...

There is extensive literature on in vivo studies with cordycepin, but these studies were generally conducted without validation of the various formulations, especially in terms of the solubility of cordycepin in the dosing vehicles used. Cordycepin is a promising drug candidate in multiple therapeutic areas, and there is a growing interest in studies aimed at assessing the pharmacological activity of this compound in relevant animal disease models. It is likely that many reported in vivo studies used formulations in which cordycepin was incompletely soluble...

It has been known from previous studies that body fluids, such as cerebrospinal fluid, lung surfactant and urine, have a strong impact on the bacterial killing of many anti-infective agents. However, the influence of human bile on the antimicrobial activity of antibiotics is widely unknown. Human bile was obtained and pooled from 11 patients undergoing cholecystectomy. After sterilisation of the bile fluid by gamma irradiation its effect on bacterial killing was investigated for linezolid (LZD) and tigecycline (TGC) against Enterococcus faecalis ATCC 29212...

Over significant areas of the UK and western Europe, anthropogenic alteration of the subsurface by mining of coal has occurred beneath highly populated areas which are now considering a multiplicity of 'low carbon' unconventional energy resources including shale gas and oil, coal bed methane, geothermal energy and energy storage. To enable decision making on the 3D planning, licensing and extraction of these resources requires reduced uncertainty around complex geology and hydrogeological and geomechanical processes...

BACKGROUND: Despite being legally available in India since 1971, barriers to safe and legal abortion remain, and unsafe and/or illegal abortion continues to be a problem. Community health workers have been involved in improving access to health information and care for maternal and child health in resource poor settings, but their role in facilitating accurate information about and access to safe abortion has been relatively unexplored. A qualitative study was conducted in Rajasthan, India to study acceptability, perspectives and preferences of women and community health workers, regarding the involvement of community health workers in medical abortion referrals...

BACKGROUND: Ovarian tissue cryopreservation has the potential to improve fertility preservation for a growing number of patients undergoing sterilising therapy, particularly where oocyte or embryo cryopreservation is not suitable. However, its success is limited by significant follicular apoptosis upon thawing, and there is wide variation in thawing protocols used with little evidence of efficacy. OBJECTIVE: To determine the best warming rates to maintain tissue viability...

Implant treatment is safe and predictable with sufficient amount and quality of bone tissue. In case of severely reduced bone tissue after a tooth was lost, augmentation of such tissue is necessary before implant embedment. Retrospective evaluation covered 380 alveolar ridge reconstructions. The study material consisted of human grafts prepared by the Department of Transplantology and Central Tissue Bank, Medical University of Warsaw. Presentation of laboratory procedures in the context of physical parameters of frozen, radiation sterilised, allogeneic corticocancellous material was presented...
