As the international community aims to reduce its reliance on fossil fuels, green hydrogen has great potential to replace methane as a clean source of fuel. A novel public engagement activity, The Hydrogen Bike, has been developed to demonstrate the production and use of green hydrogen from water. The aim of the activity is to educate, entertain and inform young people and adults so that they have an opportunity to form an opinion about the use of hydrogen as a fuel.

Through this we have found that most participants (73%) are considered to have no opinion or a neutral opinion on hydrogen before participating in The Hydrogen Bike activity. After participation 88% of those who were originally neutral or had no opinion on hydrogen self-reported a positive feeling about hydrogen. The method of data collection was quick, intuitive and suitable for an audience attracted from passing footfall.

The influence of the position of the amino acid proline in polypeptide sequences is examined by a combination of ion mobility spectrometry-mass spectrometry (IMS-MS), amino acid substitutions, and molecular modeling. The results suggest that when proline exists as the second residue from the N-terminus (i.e., penultimate proline), two families of conformers are formed. We demonstrate the existence of these families by a study of a series of truncated and mutated peptides derived from thedoi:10.1007/s13361-014-1049-y pmid:25503299 pmcid:PMC4336576 fatcat:y7aqwgsmvbaalbkasmus76e7zi

We find that every peptide from this sequence with a penultimate proline residue has multiple conformations. Substitution of Ala for Pro residues indicates that multiple conformers arise from the cis-trans isomerization of Xaa 1 -Pro 2 peptide bonds as Xaa-Ala peptide bonds are unlikely to adopt the cis isomer, and examination of spectra from a library of 58 peptides indicates that~80% of sequences show this effect. A simple mechanism suggesting that the barrier between the cis-and trans-proline forms is lowered because of low steric impedance is proposed. This observation may have interesting biological implications as well, and we note that a number of biologically active peptides have penultimate proline residues.

Ion mobility/mass spectrometry techniques are employed to investigate the binding of Zn 2+ to the nine-residue peptide hormone oxytocin (OT, Cys 1 -Tyr 2 -Ile 3 -Gln 4 -Asn 5 -Cys 6 -Pro 7 -Leu 8 -Gly 9 -NH 2 , having a disulfide bond between Cys 1 and Cys 6 residues). Zn 2+ binding to OT is known to increase the affinity of OT for its receptor [Pearlmutter, A. F., Soloff, M. S.: Characterization of the metal ion requirement for oxytocin-receptor interaction in rat mammary gland membranes.

In the absence of Zn 2+ , we find evidence for two primary OT conformations, which arise because the Cys 6 -Pro 7 peptide bond exists in both the transand cis-configurations. Upon addition of Zn 2+ , we determine binding constants in water of K A = 1.43 ± 0.24 and 0.42 ± 0.12 μM −1 , for the transand cisconfigured populations, respectively. The Zn 2+ bound form of OT, having a cross section of Ω = 235 Å 2 , has Pro 7 in the trans-configuration, which agrees with a prior report [Wyttenbach, T., Liu, D., Bowers, M. T.: Interactions of the hormone oxytocin with divalent metal ions. J. Am. Chem. Soc. 130, 5993-6000 (2008)], in which it was proposed that Zn 2+ binds to the peptide ring and is further coordinated by interaction of the C-terminal, Pro 7 -Leu 8 -Gly 9 -NH 2 , tail. The present work shows that the cis-configuration of OT isomerizes to the trans-configuration upon binding Zn 2+ . In this way, the proline residue regulates Zn 2+ binding to OT and, hence, is important in receptor binding.

Despite the widespread prevalence of generalized anxiety disorder (GAD) in later life, almost nothing is known about the neural aspects of worry in adults over the age of 60. Given the ongoing rapid increase in the older adult population, the relatively poor response rates to current interventions for late life GAD, and the effects of agerelated changes to the brain, additional research on worry neurobiology is needed. The study group comprised 15 older GAD patients and 15 matched controls whodoi:10.1016/j.pscychresns.2008.09.010 pmid:19559575 pmcid:PMC5206907 fatcat:og4oeobywbhtbl7ashsanncmve

It was expected that prefrontal cortex (PFC) volumes [medial orbital cortex (mOFC), dorsolateral cortex (DLPFC)] would show positive relations to worry scores, and weaker relations to more general measures of anxiety and depression. Negative relations were expected between amygdala volumes and worry scores. As expected, mOFC volumes were positively related to worry scores; however, DLPFC and amygdala volumes were not. The mOFC is involved in emotional decision-making under uncertain conditions and has the ability to suppress the amygdala, both of which are hypothesized functions of worry. Results are partly consistent with GAD theory and suggest that worry may involve neural areas that are also involved in the successful control of anxiety.

We determined the effectiveness of low-volume resistance exercise (EX) for the attenuation of loss of muscle mass and strength during leg immobilization. Men (N ¼ 5) and women (N ¼ 12, age 24 6 5 years, body mass index 25.4 6 3.6 kg/m 2 ) were divided into two groups: exercise (EX; n ¼ 12) and control (CON; n ¼ 5). Subjects wore a knee brace on one leg that prevented weight bearing for 14 days. Resistance exercise (EX; 80% of maximal) was performed by the immobilized limb every other day.doi:10.1002/mus.21721 pmid:20658567 fatcat:d57ddhygkfe2vhx53pwmk5cwby

There were significant losses in triceps surae CSA in the CON and EX groups (P < 0.05), but the losses were greater in CON subjects (P < 0.01). A minimal volume (140 contractions in 14 days) of resistive exercise is an effective countermeasure against immobilization-induced atrophy of the quadriceps femoris but is only partially effective for the triceps surae.
The termini of DNA strand breaks induced by internal and external factors often require processing before missing nucleotides can be replaced by DNA polymerases and the strands rejoined by DNA ligases. Polynucleotide kinase/phosphatase (PNKP) serves a critical role in the repair of DNA strand breaks by catalyzing the restoration of 5'-phosphate and 3'-hydroxyl termini. It participates in several DNA repair pathways through interactions with other DNA repair proteins, notably XRCC1 and XRCC4.doi:10.1016/j.tibs.2011.01.006 pmid:21353781 pmcid:PMC3134258 fatcat:vf6zaurdxncpzc5ifrgyltq4gy

Damage to cellular DNA is considered to be a significant factor in aging , cancer etiology and treatment    , and neurological disorders  . DNA damage, in the form of base modification, base loss and strand breaks, can be triggered by intracellular agents, primarily reactive oxygen species (ROS), as well as by exogenous agents. As a result, cells have evolved a battery of repair pathways to counter the mutational and cytotoxic consequences of DNA damage  . Strand breaks can be produced by various mechanisms, including cleavage by physical and chemical means such as ionizing radiation (IR) and ROS, and by enzymatic processes, such as those mediated by topoisomerases and DNA repair endonucleases. Thus, strand breaks do not constitute a homogeneous class of lesions and, in addition to classification based on cleavage of one or both DNA strands, strand breaks can be further subdivided based on the nature of their termini (Box 1). This review focuses on the enzyme polynucleotide kinase/phosphatase (PNKP) and its role in the repair of DNA strand breaks. PNKP possesses both 5'-kinase and 3'-phosphatase activities that are frequently required for processing of single-and double-strand break (SSB and DSB) termini     . PNKP, like several other DNA repair proteins, has become of increasing clinical interest owing to the identification of small molecule inhibitors of these enzymes
