A novel Gram-stain positive, aerobic, non-motile, non-spore-forming and rod-shaped strain designated 1204(T) was isolated from surface-sterilised stem tissue of maize planted in Fangshan District of Beijing, People's Republic of China. A polyphasic taxonomic study was performed on the new isolate. On the basis of 16S rRNA gene sequence similarity studies, this isolate belongs to the genus Microbacterium. High levels of 16S rRNA gene sequence similarity were found between strain 1204(T) and Microbacterium enclense NIO-1002(T) (98...

REVIEW
C Pignata, D D'Angelo, E Fea, G Gilli
Food safety is a critical public health issue for consumers and the food industry because microbiological contamination of food causes considerable social and economic burdens on health care. Most foodborne illness comes from animal production, but as of the mid-1990s in the United States and more recently in the European Union, the contribution of fresh produce to foodborne outbreaks has rapidly increased. Recent studies have suggested that sterilisation with nonthermal plasma could be a viable alternative to the traditional methods for the decontamination of heat-sensitive materials or food because this technique proves capable of eliminating microorganisms on surfaces without altering the substrate...

The present study aimed to evaluate the effects of systemic lipoic acid on hearing preservation after cochlear implantation. Twelve Dunkin-Hartley guinea pigs were randomly divided into two groups: the control group and the lipoic acid group. Animals in the lipoic acid group received lipoic acid intraperitoneally for 4 weeks. A sterilised silicone electrode-dummy was inserted through the round window to a depth of approximately 5 mm. The hearing level was measured using auditory brainstem responses (ABRs) prior to electrode-dummy insertion, and at 4 days and 1, 2, 3 and 4 weeks after electrode-dummy insertion...

A 9-year-old sterilised female domestic short-hair cat was referred with a history of vomiting and anorexia of 3 months' duration. Biochemistry, full-blood counts, thoracic radiographs, feline pancreatic-specific lipase, abdominal ultrasonography and feline immunodeficiency virus/feline leukaemia virus (FIV/FeLV) SNAP tests had been performed. Mild hypochloraemia and moderate hypokalaemia were evident on initial presentation. Abdominal ultrasonography initially revealed unilateral renal nodules on the left side...

Endometrioid carcinoma with a prominent squamous component has the ability to mimic pilomatrixoma. One previous case is documented of cutaneous metastasis in the upper limb derived from ovarian endometrioid carcinoma mimicking pilomatrixoma. Here, we describe a case of metastasis of endometrial endometrioid carcinoma in the distal vagina, treated with radiotherapy and later resected. The histology of the lesion was thought initially to represent pilomatrixoma; this has not previously been described in the vagina, where no hair matrix cells are normally present...

Acute dialyser reactions in patients treated by haemodialysis are uncommon. We present two cases of such reactions, both in patients using a polysulfone, steam-sterilised dialyser. Patient 1 suffered from recurrent attacks of acute dyspnoea, hypoxia and hypotension that occurred early in dialysis sessions, whereas patient 2 presented with unexplained episodes of severe hypotension and vomiting in the initial phases of dialysis. After switching to a cellulose triacetate dialyser, both patients became asymptomatic during all subsequent dialysis sessions, but intentional (patient 1) and accidental (patient 2) rechallenge with the polysulfone dialyser induced an immediate recurrence of the symptoms...

Gamma-irradiation, particularly an irradiation dose of 50kGy, has been utilised widely to sterilise highly pathogenic agents such as Ebola, Marburg Virus, and Avian Influenza H5N1. We have reported previously that intranasal vaccination with a gamma-irradiated Influenza A virus vaccine (γ-Flu) results in cross-protective immunity. Considering the possible inclusion of highly pathogenic Influenza strains in future clinical development of γ-Flu, an irradiation dose of 50kGy may be used to enhance vaccine safety beyond the internationally accepted Sterility Assurance Level (SAL)...

BACKGROUND: Female sex workers (FSWs) are extremely vulnerable to adverse sexual and reproductive health (SRH) outcomes. To mitigate these risks, they require access to services covering not only HIV prevention but also contraception, cervical cancer screening and sexual violence. To develop context-specific intervention packages to improve uptake, we identified gaps in service utilization in four different cities. METHODS: A cross-sectional survey was conducted, as part of the baseline assessment of an implementation research project...

The patient empowerment movement, spurred by AIDS activism in the 1980s, quickly evolved to encompass how study participants are considered and treated in clinical research. Initially, people fearing death of AIDS sought early access to experimental medications that had not undergone rigorous testing in hopes of extending their lives. Thirty years on, scientists are asking a different set of ethical questions about clinical research, this time in the pursuit of either a sterilising cure or long-term remission for HIV...

OBJECTIVE: In response to a persistent low fertility rate in the country, the Supreme Leader of Iran in 2012 called for the shift to pronatalist population policies. Consequently, Iran's Parliament proposed a bill to curb the provision of contraceptive knowledge and services as a solution to raising the country's low fertility rate. This study aimed to investigate which groups of women will be adversely affected if the provision of subsidised contraceptive methods [i.e. sterilisation, intrauterine device (IUD) and injections] is curbed...

The history of 'electroshock therapy' (now known as electroconvulsive therapy (ECT)) in Europe in the Third Reich is still a neglected chapter in medical history. Since Thomas Szasz's 'From the Slaughterhouse to the Madhouse', prejudices have hindered a thorough historical analysis of the introduction and early application of electroshock therapy during the period of National Socialism and the Second World War. Contrary to the assumption of a 'dialectics of healing and killing', the introduction of electroshock therapy in the German Reich and occupied territories was neither especially swift nor radical...

Although haemodialysis is an established treatment for patients with end-stage kidney disease, sustaining life for more than 2 million patients world-wide, the mortality of dialysis patients remains high and is greater than that for some of the more common solid organ cancers. As such, the question arises as to whether more efficient clearance of the waste products of metabolism which accumulate would improve outcomes. Recent reports of an association between improved patient survivals with higher-volume on-line haemodiafiltration exchanges would support this hypothesis...

Allografts eliminate the disadvantages associated with autografts and synthetic scaffolds but are associated with a disease-transmission risk. Therefore, allograft sterilisation is crucial. We aimed to determine whether polyvinylpyrrolidone-iodine (PVP-I) can be used for sterilisation and as a new wet-preservation method. PVP-I-sterilised and preserved allografts demonstrated improved mechanical property, osteogenesis, and excellent microbial inhibition. A thigh muscle pouch model of nude mice showed that PVP-I-preserved allografts demonstrated better ectopic formation than Co60-sterilised allografts (control) in vivo (P < 0...

AIM: Fungi are increasing in incidence as human pathogens and newer and rarer species are continuously being encountered. Identifying these species from growth on regular culture media may be challenging due to the absence of typical features. An indigenous and cheap medium, similar to the natural substrate of these fungi, was standardised in our laboratory as an aid to species identification in a conventional laboratory setting. MATERIALS AND METHODS: Ripe banana peel pieces, sterilised in an autoclave at 121°C temperature and 15 lbs pressure for 15 min promoted good growth of hyphae and pycnidia or acervuli in coelomycetes, flabelliform and medusoid fruiting bodies of basidiomycetes and fruit bodies such as cleistothecium in ascomycetes...

With the number of stem cell-based therapies emerging on the increase, the need for novel and efficient delivery technologies to enable therapies to remain in damaged tissue and exert their therapeutic benefit for extended periods, has become a key requirement for their translation. Hydrogels, and in particular, thermoresponsive hydrogels, have the potential to act as such delivery systems. Thermoresponsive hydrogels, which are polymer solutions that transform into a gel upon a temperature increase, have a number of applications in the biomedical field due to their tendency to maintain a liquid state at room temperature, thereby enabling minimally invasive administration and a subsequent ability to form a robust gel upon heating to physiological temperature...

The response of the intestine to (low linear-energy-transfer) ionising radiation is reviewed regarding the cellular basis to the reactions, the regenerative processes which restore the tissue, and external agents which aid its recovery. In the steady-state, it is generally considered that the crypt cell lineages in both small and large intestine are maintained by a small number of stem cells, but there are differences for example in the composition of their niche residence and in the numbers of transit cell generations...

Radioactive sources are used by hospitals, research facilities and industry for such purposes as diagnosing and treating illnesses, sterilising equipment and inspecting welds. Unfortunately, many States, regulatory authorities and licensees may not appreciate how people with malevolent intentions could use radioactive sources, and statistics confirm that a number of security incidents happen around the globe. The adversary could be common thieves, activists, insiders, terrorists and organised crime groups. Mitigating this risk requires well trained and competent staff who have developed the knowledge, attributes and skills necessary to successfully discharge their security responsibilities...

Free radicals in thermally treated chloramphenicol were examined by electron paramagnetic resonance (EPR) spectroscopy. The parameters and shape of EPR spectra were analysed and free radical concentrations were obtained in the tested drug samples. Chloramphenicol was thermally sterilized at pharmacopeia conditions: 100 °C (120 min). Sterilization was also carried out at different conditions, 110 °C (60 min) and 120 °C (30 min), for comparison with pharmacopeia settings. Microbiological analysis was performed on the samples to confirm sterility...

Sterilisation requests made by young, child-free adults are frequently denied by doctors, despite sterilisation being legally available to individuals over the age of 18. A commonly given reason for denied requests is that the patient will later regret their decision. In this paper, I examine whether the possibility of future regret is a good reason for denying a sterilisation request. I argue that it is not and hence that decision-competent adults who have no desire to have children should have their requests approved...
