Endocervical adenocarcinoma (ECA) the fatal and intrusive subtype of cervical carcinoma is on rise from the last decade. Its improper detection leads to worst clinical outcomes that urges the discovery of novel biomarkers. Therefore, we proposed insilico and invitro based approches to identify key genes that could be used as potential targeted therapies. RNA-seq and gene expression data was operated via R-programming that identified 11,592 differential expressed genes which are mainly enriched in metabolic pathways, chemical carcinogenesis-receptor activation, amoebias, MAPK and PI3K-AKT signaling pathway. Clustering modules and hub genes were retrieved to design network of immune cells with varying expression using multiple statistical algorithms. The Drugs targeting hub genes were determined from Drug gene interaction database which was further categorized for docking and dynamics based simulations. Results indicate high binding affinity of Imatinib compound into active pockets of BIRC5 which is confirmed by cell viability lab experiment. Current study demonstrates novel biomarkers and therapeutic drugs for in depth understanding of endocervical carcinogensis.

This article presents a methodology developed to assess and compare the technical, economic, safety, and environmental performance of alternative radioactive waste management options across two technologies. Value assessment is a form of multi-criteria cost–benefit analysis, enabling a holistic consideration of a wide range of attributes (e.g., operational safety, environmental impact, disposability, financial aspects, and implementability). For each attribute, several quantitative or qualitative metrics were included to ensure that the assessment was both proportionate and targeted. The methodology was applied to the treatment of contaminated metallic waste using decontamination gels, for which two formulations were investigated: a vacuumable gel developed by CEA and the Electrolytically Assisted Surface Decontamination (EASD) gel developed by NNL and C-Tech Innovation Ltd. These technologies were compared to the current baseline scenario, which involves volume reduction, cementation, and disposal as intermediate-level waste (ILW). The conclusion was that gel decontamination can lead to significant cost savings in the management of radioactively contaminated metallic waste, primarily due to waste volume reduction and the potential for diversion to alternative disposal facilities or the recycling and reuse of bulk metal.

There are currently no evidence summaries on wounds in the horse. To develop evidence-based guidelines on wound management in the horse. Evidence review using the GRADE framework. Research questions were proposed by a panel of veterinarians, and developed into PICO format. Evidence in the veterinary literature was evaluated using the GRADE evidence-to-decision framework. Searches for human evidence summaries were conducted in the NICE, Cochrane and JBI databases. Final recommendations were based on both veterinary and human evidence. The research questions were categorised into three areas: A. Wound lavage and topical treatments; B. Wound debridement and closure; C. Therapeutics for wound healing. Three hundred and six veterinary publications were identified across thirteen different topics. Fourteen papers were assessed using the GRADE criteria. Twenty-five human evidence summaries were reviewed. The results were developed into recommendations: Wound lavage and topical treatments: (i) Tap water should be considered instead of saline for lavage; (ii) Povidone iodine lavage should be considered for contaminated wounds; (iii) Topical silver sulfadiazine may not be suitable for acute wounds; (iv) Optimal lavage pressures are around 13psi. Wound debridement and closure: (i) Debridement pads should be considered for wound preparation; (ii) Larvae debridement should be considered in selected cases; (iii) Hydrosurgery should be considered in acute contaminated wounds. Therapeutics for wound healing: (i) Honey may reduce duration of some phases of wound healing. There was insufficient evidence to draw conclusions on the use of chemical debridement, therapeutic ultrasound, laser therapy, wound closure with staples compared to sutures, or identify optimal concentrations of antiseptic lavage solutions. Low quality evidence in veterinary literature; majority of recommendations were based on human evidence. These findings should be used to inform decision-making in equine primary care practice.

A flock of sheep in Central Sicily was affected by a severe outbreak of contagious agalactia (CA) caused by Mycoplasma agalactiae, affecting nearly 30% resulting in a large drop in milk production. Many ewes had warm and swollen udders that often became sclerotic and was accompanied by keratoconjunctivitis and arthritis in both adults and young. As antibiotic treatment appeared ineffective, the whole flock was given two doses of an inactivated vaccine against M agalactiae two weeks apart. A small group was selected for close examination and additional tests. A fortnight after the last vaccination mycoplasma excretion fell in all but one of the selected ewes and was undetectable in all but two animals two weeks after that. In nearly all the selected ewes, there was an improvement in milk quality and udder condition. This work provided preliminary evidence for the continued use of CA vaccines to slow or prevent disease progression.

Vixotrigine is a state‐ and use‐dependent Nav1.7 channel blocker being investigated for the treatment of neuropathic pain conditions. This randomized, double‐blind, placebo‐controlled crossover trial was designed to evaluate changes in blood pressure with the administration of vixotrigine using ambulatory blood pressure monitoring (ABPM). Eligible participants were healthy adults 18 to 65 years of age without evidence of baseline systolic blood pressure (SBP) persistently > 140 mm Hg or diastolic blood pressure (DBP) persistently > 90 mm Hg. Vixotrigine (400 mg [men], 300 mg [women]) or placebo was administered orally twice daily for 36 days. Following a 7‐day washout period, participants crossed over to the other treatment. Each dosing period was preceded by 1 inpatient visit and 1 outpatient baseline visit. Two 14‐hour inpatient ABPM sessions occurred on days 14 and 35, with a return to the clinic the morning of days 15 and 36 for initiation of outpatient ABPM, which assessed blood pressure and heart rate every 15 minutes. Adverse events were collected throughout the study. The primary end point was the change from baseline in 24‐hour mean SBP and DBP on day 36. Sixty participants were enrolled; 10 withdrew from the study owing to adverse events, investigator discretion, or withdrawal of consent. From baseline to day 36, mean changes in average SBP and DBP (vixotrigine treated) were ‐0.33 and 0.20 mm Hg, respectively. Adverse event rates were comparable for vixotrigine and placebo; the most common adverse events were headache, dizziness, and nausea. Vixotrigine administration is not associated with a clinically important increase in blood pressure.

SummaryBackgroundSuperficial digital flexor tendon (SDFT) injury is an important health and welfare concern in racehorses. It is generally diagnosed with ultrasonography, but predictive ultrasonographic features have not been reported.ObjectivesTo determine ultrasonographic features of forelimb SDFT injury at initial presentation in Thoroughbred racehorses that could predict a successful return to racing (completing ≥5 races).Study designRetrospective cohort study.MethodsDigitised ultrasonographic images of 469 horses with forelimb SDFT injuries from the Hong Kong Jockey Club (2003–2014) were evaluated, using a previously validated ultrasonographic scoring system. Six ultrasonographic parameters were evaluated (type and extent of the injury, location, echogenicity, cross‐sectional area and longitudinal fibre pattern of the maximal injury zone [MIZ]), as well as horse signalment, retirement date and number of races before and after injury. Data were analysed by generalised linear regression with significance at P<0.05.ResultsCases were divided into two groups: 1) For cases of SDFT tendonitis with core lesions, cross‐sectional area at the MIZ was the most significant factor determining a successful return to racing (P = 0.03). If the lesion was <50% of the total cross‐sectional area, horses had 29–35% probability of successfully racing again, but if it was ≥50% this decreased to 11–16%. 2) For cases of SDFT tendonitis without a core lesion, longitudinal fibre pattern at the MIZ best predicted a successful return to racing (P = 0.002); if the affected longitudinal fibre pattern was <75% of the total, horses had 49–99% probability of successfully return to racing, but if it was ≥75% this decreased to 14%.Main limitationsPrognostic information may not be applicable to other breeds/disciplines.ConclusionsThis is the first study to describe ultrasonographic features of forelimb SDFT injuries at initial presentation that were predictive of successful return to racing. The outcomes will assist with early, evidence‐based decisions on prognosis in Thoroughbred racehorses.

Many regulatory agencies allow the use of a dilution and attenuation factor in calculating cleanup goals for groundwater discharging into surface water bodies. This is important for coastal aquifers where chemical-containing groundwater from upland areas undergoes dilution within the aquifer near the shore due to mixing with intruded seawater. The cleanup goals developed with or without this dilution factor can be significantly different. This paper provides a modeling method for estimating the dilution factor using the SEAWAT program to simulate the tidally influenced variable-density flow typical in a coastal aquifer. The SEAWAT modeling was conducted at an active marine fuel terminal site near the San Francisco Bay to estimate an effective dilution factor applicable to site monitoring wells. The groundwater cleanup goals were then calculated as the marine surface water cleanup goals multiplied by the effective dilution factor. This was approved by the regulatory agency and expedited site remediation and closure.

In some countries nuclear waste facility siting programs include social and economic benefits, compensation, local empowerment and motivation measures and other incentives for the potential host community. This can generally be referred to as an ‘added value approach’. Demonstration of the safety of a repository is seen as a precondition of an added value approach. Recently much focus has been placed on studying and developing public participation approaches but less on the use of such incentive and community benefit packages, although they are becoming a more common element in many site selection strategies for nuclear waste management facilities. The primary objective of this paper is to report on an ongoing study of stakeholders’ opinions of the use of an added value approach in siting a radioactive waste facility in the Czech Republic, Poland and Slovenia. The paper argues that an added value approach should adapt to the interests and needs of stakeholders during different stages of a siting process. The main question posed in the study is as follows: What are the measures which should be included in ‘added value approach’ according to the stakeholders? The research data consists of stakeholders’ responses to a survey focusing on the use of added value (community benefits) and incentives in siting nuclear waste management facilities. The survey involved use of a questionnaire developed as part of the EU-funded IPPA* project in three countries: the Czech Republic, Poland and Slovenia. (* Implementing Public Participation Approaches in Radioactive Waste Disposal, FP7 Contract Number: 269849). The target audiences for the questionnaires were the stakeholders represented in the national stakeholder groups established to discuss site selection for a nuclear waste repository in their country. A total of 105 questionnaires were sent to the stakeholders between November 2011 and January 2012. 44 questionnaires were returned, resulting in a total response rate of 41% (10/29 in the Czech Republic, 11/14 in Poland and in 23/64 in Slovenia).

The UK Low Level Waste Repository Ltd submitted an Environmental Safety Case for the disposal of low-level waste (LLW) to the Environment Agency on the 1st of May 2011. The Environmental Safety Case (ESC) presents a complete case for the environmental safety of the Low Level Waste Repository (LLWR) both during operations and in the long term (Cummings et al, in these proceedings). This includes an assessment of the long-term radiological safety of the facility, including an assessment of the potential consequences of human intrusion at the site. The human intrusion assessment is based on a cautiously realistic approach in defining intrusion cases and parameter values. A range of possible human intrusion events was considered based on present-day technologies and credible future uses of the site. This process resulted in the identification of geotechnical investigations, a housing development and a smallholding as requiring quantitative assessment. A particular feature of the site is that, because of its proximity to the coast and in view of expected global sea-level rise, it is vulnerable to coastal erosion. During such erosion, wastes and engineered barrier materials will be exposed, and could become targets for investigation or recovery. Therefore, human intrusion events have been included that are associated with such activities. A radiological assessment model has been developed to analyse the impacts of potential human intrusion at the site. A key feature of the model is the representation of the spatial layout of the disposal site, including the engineered cap design and the large-scale spatial heterogeneity of radionuclide concentrations within the repository. The model has been used to calculate the radiation dose to intruders and to others following intrusion at different times and at different locations across the site, for the each of the selected intrusion events, considering all relevant exposure modes. Potential doses due to radon and its daughters in buildings constructed on excavated spoil from the repository are a particular concern. Options for managing the emplacement of the radium-bearing waste packages with regard to human intrusion have been assessed. These calculations show that a managed waste emplacement strategy can ensure that calculated doses are consistent with regulatory guidance levels.
