The assembly of multi-protein complexes requires the concerted synthesis and maturation of its components and subsequently their co-ordinated interaction. The membrane-bound formate hydrogenlyase (FHL) complex is the primary hydrogen-producing enzyme in Escherichia coli and is composed of seven subunits mostly encoded within the hycA-I operon for [NiFe]-hydrogenase-3 (Hyd-3). The HycH protein is predicted to have an accessory function and is not part of the final structural FHL complex. In this work, a mutant strain devoid of HycH was characterized and found to have significantly reduced FHL activity due to instability of the electron transfer subunits...

Diabetes mellitus (DM) is a non-communicable, metabolic disorder that affects 416 million individuals worldwide. Type 2 diabetes contributes to a vast 85-90% of the diabetes incidences while 10-15% of patients suffer from type 1 diabetes. These two predominant forms of DM cause a significant loss of functional pancreatic β-cell mass causing different degrees of insulin deficiency, most likely, due to increased β-cell apoptosis. Treatment options involve the use of insulin sensitisers, α-glucosidase inhibitors, and β-cell secretagogues which are often expensive, limited in efficacy and carry detrimental adverse effects...

#4
REVIEW
Jonas Franz, Marco Tarantola, Christoph Riethmüller
Tetraspanins are ubiquitous membrane proteins that induce local membrane curvature and hence co-ordinate cell-to-cell contacts. This review highlights their role in inflammation, which requires control of the nano-architecture of attachment sites between endothelial cells and leukocytes. The active role of endothelial cells in preparing for transmigration of leukocytes and determining the severity of an inflammation is often underscored. A clear hint to endothelial pre-activation is their ability to protrude clustered adhesion proteins upward prior to leukocyte contact...

The ability to reproduce novel words is a sensitive marker of language impairment across a variety of developmental disorders. Nonword repetition tasks are thought to reflect phonological short-term memory skills. Yet, when children hear and then utter a word for the first time, they must transform a novel speech signal into a series of coordinated, precisely timed oral movements. Little is known about how children's oromotor speed, planning and co-ordination abilities might influence their ability to repeat novel nonwords, beyond the influence of higher-level cognitive and linguistic skills...

BACKGROUND: People with stroke conventionally receive a substantial part of their rehabilitation in hospital. Services have now been developed that offer people in hospital an early discharge with rehabilitation at home (early supported discharge: ESD). OBJECTIVES: To establish if, in comparison with conventional care, services that offer people in hospital with stroke a policy of early discharge with rehabilitation provided in the community (ESD) can: 1) accelerate return home, 2) provide equivalent or better patient and carer outcomes, 3) be acceptable satisfactory to patients and carers, and 4) have justifiable resource implications use...

Isopenicillin N synthase (IPNS) catalyses the oxidation of a tripeptide, L-δ-(α-aminoadipoyl)-L-cysteinyl-D-valine (ACV), to isopenicillin N (IPN), the first-formed β-lactam in penicillin biosynthesis. IPNS catalysis is dependent upon an iron(II) cofactor and oxygen as co-substrate. In the absence of substrate, the carbonyl oxygen of the side-chain amide of the penultimate residue, Gln330, co-ordinates to the active site metal. Substrate binding ablates this interaction, triggering rearrangement of seven C-terminal residues which move to take up a conformation that extends the final α-helix and encloses the active site...

The formation of metal chelates with various ligands may lead to the production of fluorescent chelates or enhance the fluorescence of the chelating agent. This paper describes two sensitive, selective and computer-solved methods, namely, zero order (SF) and second-derivative synchronous spectrofluorimetry (SDSFS) for nano-quantitation of two carbapenems; meropenem (MP) and ertapenem (EP). The methods are based on the chelation of MP with Tb(3+) and EP with Zr(4+) in buffered organic medium at pH 4.0 to produce fluorescent chelates...

Arabidopsis (Arabidopsis thaliana) seed development requires the concomitant development of two zygotic compartments, the embryo and the endosperm. Following fertilization, the endosperm expands and the embryo grows invasively through the endosperm, which breaks down. Here we describe a structure we refer to as the embryo sheath that forms on the surface of the embryo as it starts to elongate. The sheath is deposited outside the embryonic cuticle, and incorporates endosperm-derived material rich in extensin-like molecules...

Fibrinolysis is a cascade of proteolytic reactions occurring in blood and soft tissues, which functions to disintegrate fibrin clots when they are no more needed. In order to elucidate its regulation in space and time, fibrinolysis was investigated using an in vitro reaction-diffusion experimental model of blood clot formation and dissolution. Clotting was activated by a surface with immobilized tissue factor in a thin layer of recalcified blood plasma supplemented with tissue plasminogen activator (TPA), urokinase plasminogen activator or streptokinase...

Pancreatic β-cells are connected to neighboring endocrine cells through the adherin proteins and gap junctions. Connexin 36 (Cx36) is one of the most well-studied and abundantly expressed gap-junction proteins within rodent islets, which is important in coordinated insulin secretion. The expression of connexins is regulated at various levels and by several mechanisms; one of which is via microRNAs. In past 2 decades, microRNAs (miRNAs) have emerged as key molecules in developmental, physiologic and pathological processes...

OBJECTIVE: Antiphospholipid syndrome (APS) leukocytes exhibit an oxidative perturbation, directly linked to alterations in mitochondrial dynamics and metabolism. This disturbance is related to the patients' prothrombotic status and can be prevented by in vitro treatment with coenzyme Q10. Our aim was to investigate short-term effects of in vivo ubiquinol (reduced coenzyme Q10[Qred]) supplementation on markers related to inflammation and thrombosis in APS through a prospective, randomized, crossover, placebo-controlled trial...

Microorganisms are the main mechanisms of pollutants removals in constructed wetlands (CWs) used for wastewater treatment. However, the different biological processes and variations of prokaryotic community in CWs remain poorly understood. In this study, we applied a high-throughput sequencing technique to investigate the prokaryotic communities associated with sediments from pilot-scale surface-flow constructed wetlands (SFCWs) treating swine wastewater (SW) of varying strengths. Our results revealed that highly diverse prokaryotic communities were present in the SFCWs, with Proteobacteria (16...

Co-production involves knowledge and skills based on both lived experiences of citizens and professionally training of staff. In Europe, co-production is viewed as an essential tool for meeting the demographic, political and economic challenges of welfare states. However, co-production is facing challenges because public services and civil society are rooted in two very different logics. These challenges are typically encountered by provider organisations and their staff who must convert policies and strategies into practice...

Despite a trend towards universal testing, best practice to screen patients presenting with gynaecological malignancy for Lynch syndrome (LS) is uncertain. We report our institutional experience of a co-ordinated gynaecological LS screening program. All patients with endometrial carcinoma or carcinosarcoma, or gynaecological endometrioid or clear cell carcinomas undergo reflex four panel immunohistochemistry (IHC) for MLH1, PMS2, MSH2 and MSH6 followed by cascade somatic hypermethylation analysis of the MLH1 promoter locus for dual MLH1/PMS2 negative tumours...

The "Campania Salute" (CS) is a network system aimed at improving the management of essential hypertension by integrating the activity of general practitioners (GPs) with that of the hypertension specialists. It involves 23 outpatient hypertensive clinics distributed in different community hospitals of the Napoli's metropolitan area, 60 randomly selected GPs homogeneously distributed in the same area, and the Hypertension Clinic of the Federico II University in Naples (co-ordinating centre). Through the CS system it is possible to share clinical data collected during each visit at peripheral units (general practitioners and community hospitals hypertensive clinics), which manage low-risk hypertensive patients, and the co-ordinating centre, which mainly manages high-risk hypertensive patients...

Schmallenberg virus (SBV) caused a large scale epidemic in Europe from 2011 to 2013, infecting ruminants and causing foetal deformities after infection of pregnant animals. The main impact of the virus was financial loss due to restrictions on trade of animals, meat and semen. Although effective vaccines were produced, their uptake was never high. Along with the subsequent decline in new SBV infections and natural replacement of previously exposed livestock, this has resulted in a decrease in the number of protected animals...
