The analysis showed that all three possible pollution sources contributed to the Cd in the rice grains in the field, the average Cd contribution of industrial dust, agricultural fertilizers and automobile exhaust was 87%, 9%, and 4%, respectively. Our study provides a feasible method for the identification of pollution sources of Cd in rice grains at the field scale and demonstrates that Cd isotopic composition is one of the powerful tools to trace the pollution sources of Cd in crops.Changes in the environment as a result of industrialisation and urbanisation impact negatively on plant growth and crop production. Cadmium (Cd) is one of the most dangerous metals that enters the food chain, with toxic effects on plants and human health. This study evaluated the potential of Silene sendtneri as a novel hyperaccumulator and the role of seed priming in tolerance and accumulation rate of Cd. The effect of different priming agents on germination performance, root growth, seedling development, metal uptake and accumulation, antioxidant defences including enzymatic and non-enzymatic antioxidants has been assessed. Seed priming using silicic acid, proline alone or in combination with salicylic acid- enhanced germination, seedling development, and root growth under Cd stress. The same priming treatments induced an increase of water content in shoots and roots when plants were exposed to Cd. The enzymatic antioxidant response was specific for the priming agent used. An increase in ferulic acid and rutin in shoots was related to the increase of Cd concentration in the medium. The concentration of malic and oxalic acid increased significantly in shoots of plants grown on high Cd concentrations compared to low Cd concentrations. Silene sendtneri can accumulate significant levels of Cd with enhanced accumulation rate and tolerance when seeds are primed. The best results are obtained by seed priming using 1% silicic acid, proline and salicylic acid.Mentally ill offenders have a right to a fair trial and adequate treatment in terms of the law. The diversion of mentally ill offenders between the criminal justice and the mental health care systems is linked to the forensic psychiatric assessment and based on two psycho-legal constructs, fitness to stand trial (FTST) and criminal responsibility (CR). Forensic psychiatric assessment is therefore an important element in criminal law and plays a major role in the court's decisions regarding the sentence, detention, placement, or treatment of mentally ill offenders. The legislation aims to ensure balancing the rights of mentally ill offenders to psychiatric care and society's safety. A narrative overview of the literature summarizing the findings on legislation regulating FTST and CR assessment and their practice in different areas of the world was conducted. It offers insight into the advantages and disadvantages of the various approaches and examines the way court proceedings function in these different geographical and psychosocial-legal contexts. This may have policy implications for individual systems and allow countries to consider feasible mechanisms to refine the relevant legislation to improve their practices in forensic psychiatric assessments. Worldwide, relevant legislation is considered as essential in protecting mentally ill offender's right; it has been established for many years regarding specifying the procedures and responsibilities for the mental health care and criminal justice systems. Despite similarities in the principles of the psycho-legal constructs in different countries, there are differences in the way legislations are implemented, often depending on the available resources.This article investigates the lawfulness of isolating residents of care and group homes during the COVID-19 pandemic. PDGFR 740Y-P ic50 Many residents are mobile, and their freedom to move is a central ethical tenet and human right. It is not however an absolute right and trade-offs between autonomy, liberty and health need to be made since COVID-19 is highly infectious and poses serious risks of critical illness and death. People living in care and group homes may be particularly vulnerable because recommended hygiene practices are difficult for them and many residents are elderly, and/or have co-morbidities. In some circumstances, the trade-offs can be made easily with the agreement of the resident and for short periods of time. However challenging cases arise, in particular for residents and occupants with dementia who 'wander', meaning they have a strong need to walk, sometimes due to agitation, as may also be the case for some people with developmental disability (e.g. autism), or as a consequence of mental illness. This article addresses three central questions (1) in what circumstances is it lawful to isolate residents of social care homes to prevent transmission of COVID-19, in particular where the resident has a strong compulsion to walk and will not, or cannot, remain still and isolated? (2) what types of strategies are lawful to curtail walking and achieve isolation and social distancing? (3) is law reform required to ensure any action to restrict freedoms is lawful and not excessive? These questions emerged during the first wave of the COVID-19 pandemic and are still relevant. Although focussed on COVID-19, the results are also relevant to other future outbreaks of infectious diseases in care and group homes. Likewise, while we concentrate on the law in England and Wales, the analysis and implications have international significance.Human macrophages play a major role in controlling tuberculosis (TB), but their anti-mycobacterial mechanisms remain unclear among individuals with metabolic alterations like obesity (TB protective) or diabetes (TB risk). To help discern this, we aimed to i) Evaluate the impact of the host's TB status or their comorbidities on the anti-mycobacterial responses of their monocyte-derived macrophages (MDMs), and ii) determine if the autophagy inducer rapamycin, can enhance these responses. We used MDMs from newly diagnosed TB patients, their close contacts and unexposed controls. The MDMs from TB patients had a reduced capacity to activate T cells (surrogate for antigen presentation) or kill M. tuberculosis (Mtb) when compared to non-TB controls. The MDMs from obese participants had a higher antigen presenting capacity, whereas those from chronic diabetes patients displayed lower Mtb killing. The activation of MDMs with rapamycin led to an enhanced anti-mycobacterial activity irrespective of TB status but was not as effective in patients with diabetes.
