Exopolysaccharides play an important role in the physiology of a bacterial cell. Ensifer meliloti is capable of producing at least two types of exopolysaccharides (EPS): succinoglycan and galactoglucan. In E. meliloti, EPS are best known for their role in mediating interaction with its symbiotic hosts. It was previously shown that high concentrations of Mg2+ or K+ were capable of suppressing the mucoid phenotype associated with galactoglucan production in an expR+ derivative of Rm1021. In an attempt to determine how Mg2+ regulates galactoglucan production, SRmD363 was mutagenised and screened for mutants which were visibly mucoid at high concentrations of magnesium...

The β₃ adrenergic receptor is raising as an important drug target for the treatment of pathologies such as diabetes, obesity, depression, and cardiac diseases among others. Several attempts to obtain selective and high affinity ligands have been made. Currently, Mirabegron is the only available drug on the market that targets this receptor approved for the treatment of overactive bladder. However, the FDA (Food and Drug Administration) in USA and the MHRA (Medicines and Healthcare products Regulatory Agency) in UK have made reports of potentially life-threatening side effects associated with the administration of Mirabegron, casting doubts on the continuity of this compound...

AIMS: The UK Medicines and Healthcare products Regulatory Agency (MHRA) runs a national spontaneous reporting system (Yellow Card [YC] Scheme) to collect 'suspected' adverse drug reaction (ADR) data. We aim to describe the content and utility of YC reports received for patients aged <2 years. METHODS: Data on all ADRs reported using YC in infants aged <2 years from the years 2001-10 were supplied by the MHRA. RESULTS: For infants age <2 years, 3496 suspected ADRs were reported using YC (paternal medication pre-conception n = 3, transplacental n = 246, transmammary n = 30, neonates n = 97, infant n = 477, and vaccinations n = 2673), averaging 0...

Domperidone is a dopamine D2 receptor antagonist acting on the chemoreceptor trigger zone in the medulla and also in the gut, causing antiemetic and gastrokinetic effects respectively. In the past, domperidone was considered largely safe, with many indications and few contraindications listed in the product literature. In 2014, Domperidone became indicated only for the prevention of nausea and vomiting and the duration of treatment was limited to seven days. Furthermore, the maximum daily dose was limited to thirty milligrams...

Mechanistic home range analysis (MHRA) is a highly effective tool for understanding spacing patterns of animal populations. It has hitherto focused on populations where animals defend their territories by communicating indirectly, e.g. via scent marks. However, many animal populations defend their territories using direct interactions, such as ritualized aggression. To enable application of MHRA to such populations, we construct a model of direct territorial interactions, using linear stability analysis and energy methods to understand when territorial patterns may form...

Registries are powerful tools to support manufacturers in the fulfilment of their obligations to perform post-market surveillance and post-market clinical follow-up of implantable medical devices. They are also a valuable resource for regulators in support of regulatory action as well as in providing information around the safety of new and innovative technologies. Registries can provide valuable information on the relative performance of both generic types and manufacturer's individual products and they complement other sources of information about device performance such as post-market clinical studies and adverse incident reporting...

Role of progesterone in reproductive medicine is evolving with its suggested clinical role for the hormonal and nonhormonal actions in reproductive medicine. The main function of progesterone is to induce 'secretory' changes in endometrium that is further complimented by its immunomodulatory and anti-inflammatory actions. It positively modulates PIBF, NK cells and HOXA 10 genes for better implantation. MHRA recommends Serum Progesterone levels ≥14ng/ml in the mid-luteal phase for supporting pregnancy adequately...
