The syntheses of three platinum(II) complexes bearing sulfonamide- ( (E)-2-(4-methylphenylsulfonamido)-2',6'-difluoroazobenzene, HL1) and hydroxy-azo-2,6-difluorobenzene ((E)-2-((2,6-difluorophenyl)diazenyl)phenol, HL2) bidentate ligands is described. These complexes, [Pt(L1)(DMSO)Cl] (1), [Pt(L2)(DMSO)Cl] (2), and [Pt(L2)2] (3), were characterized by multinuclear NMR spectroscopy, mass spectrometry, and X-ray crystallography. Despite bearing azobenzene functional groups, none of the three complexes undergo photoisomerization...

Transient gene expression in mammalian cells is an efficient process for producing recombinant proteins for various research applications to support large molecule therapeutics development. For the first time, we report a high throughput small molecule (SM) screen to identify novel compounds that increase antibody titers after polyethylenimine (PEI) transient transfection of a HEK293 cell line. After screening 31,413 SMs in a 50 μL scaled-down process, we validated 164 SMs to improve yields by up to 2-fold...

A potential therapeutic role for immune transformation in Parkinson's disease evolves from more than a decade of animal investigations demonstrating regulatory T cell (Treg) nigrostriatal neuroprotection. To bridge these results to human disease, we conducted a randomized, placebo-controlled double-blind phase 1 trial with a well-studied immune modulator, sargramostim (granulocyte-macrophage colony-stimulating factor). We enrolled 17 age-matched non-Parkinsonian subjects as non-treated controls and 20 Parkinson's disease patients...

The number of companion animal wellness visits in private practice has been decreasing, and one important factor cited is the lack of effective communication between veterinarians and pet owners regarding the importance of preventive care. Checklists have been widely used in many fields and are especially useful in areas where a complex task must be completed with multiple small steps, or when cognitive fatigue is evident. The use of checklists in veterinary medical education has not yet been thoroughly evaluated as a potential strategy to improve communication with pet owners regarding preventive care...

OBJECTIVE: To examine possible etiology and treatment outcomes in 21 patients with glans necrosis following penile prosthesis implantation. METHODS: Glans necrosis typically presented with a dusky glans on first post-operative day following prosthesis implantation. RESULTS: The blood supply to the glans penis consists of the dorsal arteries and the terminal branches of the spongiosal arteries. Using this cohort, we compiled pre-operative comorbidities and adjunctive surgical maneuvers that might compromise glans vascularity leading to glans necrosis...

The detection of repetitive deliberate fire events is challenging and still often ineffective due to a case-by-case approach. A previous study provided a critical review of the situation and analysis of the main challenges. This study suggested that the intelligence process, integrating forensic data, could be a valid framework to provide a follow-up and systematic analysis provided it is adapted to the specificities of repetitive deliberate fires. In this current manuscript, a specific methodology to detect deliberate fires series, i...

REVIEW
Nicholas C Wu, Ian A Wilson
Influenza virus evolves rapidly to constantly escape from natural immunity. Most humoral immune responses to influenza virus target the hemagglutinin glycoprotein (HA), which is the major antigen on the surface of the virus. The HA is comprised of a globular head domain for receptor binding and a stem domain for membrane fusion. The major antigenic sites of HA are located in the globular head subdomain, which is highly tolerant of amino-acid substitutions and continual addition of glycosylation sites. Nonetheless, the evolution of the receptor-binding site (RBS) and the stem region on HA is severely constrained by their functional roles in engaging the host receptor and in mediating membrane fusion, respectively...

Thermostable α-amylases have many industrial applications and are therefore continuously explored from novel sources. We present the characterization of a novel putative α-amylase gene product (Tp-AmyS) cloned from Thermotoga petrophila. The purified recombinant enzyme is highly thermostable and able to hydrolyze starch into dextrin between 90 and 100°C, with optimum activity at 98°C and pH8.5. The activity increased in the presence of Rb(1+), K(1+) and Ca(2+) ions, whereas other ions inhibited activity...

BACKGROUND AND AIMS: Only a few epidemiological studies on the incidence and prevalence of Wilson's disease (WD) have been performed to date, and the results vary widely according to the reports. The aim of the study was to investigate the prevalence, ambulatory care and treatments of patients with WD in France. METHODS: Among the 58 million general health scheme beneficiaries (86% of the French population), people managed for WD in 2013 were identified using hospitalisation diagnosis in 2011-2013 or specific long-term disease status with a 100% reimbursement for specific healthcare in 2013...

In their target article, Hardy and colleagues outline some psychosocial factors that were proposed to underpin the development of serial sporting champions. In this commentary, we suggest that the psychodynamic compensatory mechanisms model described by Hardy et al. is limited by its failure to consider the role of the broader developmental systems in which an individual exists (including funding structure, community, culture, and historical niche). We suggest that any workable talent development model needs to consider the bidirectional relationships between individuals and their contexts, and as such, should be guided by a more dynamic, developmental systems theory approach...

OBJECTIVE: There is growing international interest in advancing 'the tobacco endgame'. We use New Zealand (Smokefree goal for 2025) as a case study to model the impacts on smoking prevalence (SP), health gains (quality-adjusted life-years (QALYs)) and cost savings of (1) 10% annual tobacco tax increases, (2) a tobacco-free generation (TFG), (3) a substantial outlet reduction strategy, (4) a sinking lid on tobacco supply and (5) a combination of 1, 2 and 3. METHODS: Two models were used: (1) a dynamic population forecasting model for SP and (2) a closed cohort (population alive in 2011) multistate life table model (including 16 tobacco-related diseases) for health gains and costs...

All Leishmania spp. parasites are introduced into mammalian skin through a sand fly bite, but different species cause distinct clinical outcomes. Mouse studies suggest early responses are critical determinants of subsequent adaptive immunity in leishmaniasis, yet few studies address the role of keratinocytes, the most abundant cell in the epidermis. We hypothesized Leishmania infection causes keratinocytes to produce immunomodulatory factors that influence the outcome of infection. Incubation of primary or immortalized human keratinocytes with Leishmania infantum or Leishmania major, which cause visceral or cutaneous leishmaniasis, respectively, elicited dramatically different responses...

Hypomagnesaemia can arise from a variety of causes but is particularly prevalent in cancer populations. This case report describes a patient with recurrent symptomatic hypomagnesaemia, on the background of advanced ovarian cancer and a high-output ileostomy, who was successfully managed on a daily continuous subcutaneous infusion of magnesium via a syringe pump. There is limited published information on the subcutaneous administration of magnesium and, to our knowledge, this is the first case to report its routine delivery over 24 hours in a syringe pump...

Myocardial infarction is the global leading cause of mortality (Go AS et al. 2014). Coronary artery occlusion is its main etiology and it is commonly treated by Coronary Artery Bypass Graft (CABG) surgery (Wilson CT 2007). The long-term outcome remains unsatisfactory (Benedetto U 2016). The vein faces the phenomenon of restenosis during the post-surgery, which consists of re-occlusion of the lumen and usually requires secondary intervention even within one year after the initial surgery (Harskamp RE 2013). We propose an extensive study of the restenosis phenomenon by implementing two mathematical models previously developed: a heuristic Dynamical System (DS) (Garbey M and Berceli SA 2013), and a stochastic Agent Based Model (ABM) (Garbey M et al...
