At its most fundamental level, touch sensation requires the translation of mechanical energy into mechanosensitive ion channel opening, thereby generating electro-chemical signals. Our understanding of this process, especially how the cytoskeleton influences it, remains unknown. Here we demonstrate that mice lacking the α-tubulin acetyltransferase Atat1 in sensory neurons display profound deficits in their ability to detect mechanical stimuli. We show that all cutaneous afferent subtypes, including nociceptors have strongly reduced mechanosensitivity upon Atat1 deletion, and that consequently, mice are largely insensitive to mechanical touch and pain. We establish that this broad loss of mechanosensitivity is dependent upon the acetyltransferase activity of Atat1, which when absent leads to a decrease in cellular elasticity. By mimicking α-tubulin acetylation genetically, we show both cellular rigidity and mechanosensitivity can be restored in Atat1 deficient sensory neurons. Hence, our results indicate that by influencing cellular stiffness, α-tubulin acetylation sets the force required for touch.

Published: December 2016

The selection of suitable reference genes is crucial to accurately evaluate and normalize the relative expression level of target genes for gene function analysis. However, commonly used reference genes have variable expression levels in developing skeletal muscle. There are few reports that systematically evaluate the expression stability of reference genes across prenatal and postnatal developing skeletal muscle in mammals. Here, we used quantitative PCR to examine the expression levels of 15 candidate reference genes (ACTB,GAPDH,RNF7,RHOA,RPS18,RPL32,PPIA,H3F3,API5,B2M,AP1S1,DRAP1,TBP,WSB, andVAPB) in porcine skeletal muscle at 26 different developmental stages (15 prenatal and 11 postnatal periods). We evaluated gene expression stability using the computer algorithms geNorm, NormFinder, and BestKeeper. Our results indicated thatGAPDHandACTBhad the greatest variability among the candidate genes across prenatal and postnatal stages of skeletal muscle development.RPS18,API5, andVAPBhad stable expression levels in prenatal stages, whereasAPI5,RPS18,RPL32, andH3F3had stable expression levels in postnatal stages.API5andH3F3expression levels had the greatest stability in all tested prenatal and postnatal stages, and were the most appropriate reference genes for gene expression normalization in developing skeletal muscle. Our data provide valuable information for gene expression analysis during different stages of skeletal muscle development in mammals. This information can provide a valuable guide for the analysis of human diseases.
A large and unusually colored new snake species of the genusTantilla(Squamata; Colubridae) from the Peruvian Andes
Authors: Koch Claudia , Venegas Pablo J.
Published: December 2016

A new colubrid species of the genusTantillafrom the dry forest of the northern Peruvian Andes is described on the basis of two specimens, which exhibit a conspicuous sexual dimorphism.Tantilla tjiasmantoisp. nov. represents the third species of the genus in Peru. The new species is easily distinguished from its congeners by the combination of scalation characteristics and the unusual transversely-banded color pattern on the dorsum. A detailed description of the skull morphology of the new species is given based on micro-computed tomography images. The habitat of this new species is gravely threatened due to human interventions. Conservation efforts are urgently needed in the inter-Andean valley of the Maranon River.
Suppressing breakers with polar oil films: Using an epic sea rescue to model wave energy budgets
Authors: Cox Charles S. , Zhang Xin , Duda Timothy F.
Published: December 2016

Oil has been used to still stormy seas for centuries, but the mechanisms are poorly understood. Here we examine the processes by using quantitative information from a remarkable 1883 sea rescue where oil was used to reduce large breakers during a storm. Modeling of the oil film's extent and waves under the film suggests that large breakers were suppressed by a reduction of wind energy input. Modification of surface roughness by the film is hypothesized to alter the wind profile above the sea and the energy flow. The results are central to understanding air‐sea momentum exchange, including its role in such processes as cyclone growth and storm surge, although they address only one aspect of the complex problem of wind interaction with the ocean surface.

Published: December 2016

Zn(II)–porphyrin sensitizers, coded as SGT‐020 and SGT‐021, are designed and synthesized through donor structural engineering. The photovoltaic (PV) performances of SGT sensitizer‐based dye‐sensitized solar cells (DSSCs) are systematically evaluated in a thorough SM315 as a reference sensitizer. The effect of the donor ability and the donor bulkiness on photovoltaic performances is investigated for establishing the structure–performance relationship in the platform of porphyrin‐triple bond‐benzothiadiazole‐acceptor sensitizers. By introducing a more bulky fluorene unit to the amine group in the SM315, the power conversion efficiency (PCE) is enhanced with the increased short‐circuit current (Jsc) and open‐circuit voltage (Voc), due to the improved light‐harvesting ability and the efficient prevention of charge recombination, respectively. As a consequence, a maximum PCE of 12.11% is obtained for SGT‐021, whose PCE is much higher than the 11.70% PCE for SM315. To further improve their maximum efficiency, the first parallel tandem DSSCs employing cobalt electrolyte in the top and bottom cells are demonstrated and an extremely high efficiency of 14% is achieved, which is currently the highest reported value for tandem DSSCs. The series tandem DSSCs give a remarkably high Voc value of >1.83 V. From this DSSC tandem configuration, 7.4% applied bias photon‐to‐current efficiency is achieved for solar water splitting.
Photoredox Catalysis in Organophosphorus Chemistry
Authors: Luo Kai , Yang Wen‐Chao , Wu Lei
Published: December 2016

The vernal blooming of green chemistry has contributed to the development of visible light catalysis. Active radical species are generated from catalytic amounts of photosensitizers, such as transition‐metal complexes and organic dyes, upon visible light irradiation. Stoichiometric amounts of oxidants, reductants, and radical initiators are avoided in most cases. Thus, reactions proceed under milder conditions with a broader functional group tolerance than found by other methods. Photoredox catalysis has been used to form C−C and C−X (X=O, N, and S) bonds but is comparably underdeveloped in organophosphorus chemistry. Herein, we summarize advances in photoredox catalysis that involve organophosphorus chemistry. The synthesis of organophosphorus compounds by photoredox catalysis, transition‐metal complex/photoredox dual catalytic systems, and photoredox catalysis with phosphorus organocatalysts are discussed. The shortcomings and possible future trends of this chemistry are also presented.
Metal‐Free Visible‐Light‐Induced Trifluoromethylation Reactions

Published: December 2016

Visible‐light‐induced trifluoromethylation reactions of alkenes with CF3I in the presence of Nile red, which acted as an organic photosensitizer, have been developed. Compared to trifluoromethylations with transition‐metal‐based photosensitizers like Ru and Ir complexes, the use of Nile red made this process more environmentally benign, not only by avoiding issues associated with metal residues, but also by allowing the use of low‐energy photons (yellow LEDs) owing to its light absorbance at long wavelengths (440–600 nm). In the process, trifluoromethylated alkene and trifluoromethylated iodoalkane products were selectively synthesized by controlling the reaction conditions. In particular, the base employed significantly affected the selectivity of the process. The iodotrifluoromethylation of alkynes and the trifluoromethylation of N‐heterocycles also proceeded well using Nile red. Furthermore, it was found that a .CF3 radical could be generated in the absence of Nile red under a higher photon energy by visible‐light‐induced electron transfer between tertiary amines and CF3I, despite the lower reactivity.
Sinusitis in patients on tumor necrosis factor alpha inhibitors
Authors: Wang Cynthia S. , Honeybrook Adam , Chapurin Nikita , Keswani Anjeni , Jang David W.
Published: December 2016

Background

Tumor necrosis factor alpha (TNF‐α) inhibitors have revolutionized treatment of many inflammatory diseases. Sinusitis after initiation of TNF‐α inhibitors has been observed, but has not been well described in the literature. We aim to characterize the clinical features of sinusitis in patients on anti‐TNF‐α therapy.

Methods

This is a retrospective chart review of 28 patients on a TNF‐α inhibitor diagnosed with sinusitis by otolaryngologists at Duke University. Patient demographics, sinusitis characteristics, and treatment course were studied by chart review.

Results

The prevalence of sinusitis diagnosed and treated by an otolaryngologist was less than 1%. Of the 28 patients studied, 12 (42.9%) had a history of preexisting sinusitis and 16 (57.1%) had new‐onset sinusitis. 71.4% were diagnosed with chronic rhinosinusitis without polyps (CRSsNP), with disease mainly involving the maxillary and ethmoid sinuses. No patients had major extrasinus complications or required hospital admission or intravenous (IV) antibiotics. 35.7% (n = 10), including 44% (7/16) of new‐onset patients required a surgical intervention after initiating anti‐TNF therapy. 14.3% (n = 4) of the cohort had improvement in sinonasal symptoms after stopping, changing, or holding doses of the TNF‐α inhibitor.

Conclusion

Anti‐TNF‐α therapy can be associated with new‐onset sinusitis, mainly CRSsNP. Overall, the percentage of patients on a TNF‐α inhibitor seeking consultation from an otolaryngologist is low. While some patients with new‐onset sinusitis will require surgery, modification of anti‐TNF‐α therapy should be considered as an option in the medical management of these patients.

Published: December 2016

The integration of dynamic covalent bonds into macrocycles has been a tremendously successful strategy for investigating noncovalent interactions and identifying effective host–guest pairs. While numerous studies have focused on the dynamic responses of macrocycles and larger cages to various guests, the corresponding constitutionally dynamic chemistry of cryptands remains unexplored. Reported here is that cryptands based on orthoester bridgeheads offer an elegant entry to experiments in which a metal ion selects its preferred host from a dynamic mixture of competing subcomponents. In such dynamic mixtures, the alkali metal ions Li+, Na+, K+, Rb+, and Cs+ exhibit pronounced preferences for the formation of cryptands of certain sizes and donor numbers, and the selection is rationalized by DFT calculations. Reported is also the first self‐assembly of a chiral orthoester cryptate and a preliminary study on the use of stereoisomers as subcomponents.

The José Guadalupe Posada Collection of the Ibero‐American Institute, Prussian Cultural Heritage Foundation – a Case Study on Digitization and its Impacts on the Work in Libraries. Digitization in a broader sense and digitization of printed cultural heritage especially have brought about many changes regarding the tasks and responsabilities of research librarians. New ways of thinking and acting are required as the objects and their mobile and connective qualities come into focus. These alterations stand in such contrast to the traditional ‘librarian’, that the concept of the ‘embedded librarian’ has arisen. A digitization project completed recently at the Ibero‐American Institute in Berlin will serve as an example to shed some light on this new phenomenon of librarianship.

Published: December 2016

A novel fluorescent sensor, 1‐((2‐hydroxynaphthalen‐1‐yl)methylene)urea (ocn) has been designed and applied as a highly selective and sensitive fluorescent probe for recognition of Al3+ in Tris–HCl (pH = 7.20) solution. The probe ocn exhibits an excellent selectivity to Al3+ over other examined metal ions, anions and amino acids with a prominent fluorescence ‘turn‐on’ at 438 nm. ocn binds to Al3+ with a 2:1 binding stoichiometry and the detection limit was 0.3 μM. Furthermore, its capability of biological application was evaluated and the results showed that the sensor could be used to detect Al3+ in living cells.
Highly Conductive and Lightweight Composite Film as Polysulfide Reservoir for High‐Performance Lithium–Sulfur Batteries

Published: December 2016

Lithium–sulfur (Li−S) batteries are one of the most promising candidates for the next generation of energy‐storage devices owing to their high theoretical energy and low cost. However, low practical energy density and poor cycling life are obstacles to the practical application of Li−S batteries. A highly conductive and lightweight poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate–carbon nanotube (PEDOT:PSS‐CNT) interlayer for Li−S batteries has been fabricated. The PEDOT:PSS‐CNT interlayer not only acts as a soft buffer to scavenge excess lithium polysulfides in the pores and restricts polysulfides from migrating to the lithium anode by chemical absorption, but also serves as an assisted “current collector” to improve the electronic conductivity for the sulfur cathode. With these synergistic contributions, pure sulfur cathode with the PEDOT:PSS‐CNT interlayer shows a high capacity (921 mA h g−1at 0.5 C; 1 C=1675 mA h g−1), enhanced cycling performance (a capacity retention of 70.9 % after 200 cycles), and good rate performance. The excellent electrochemical performance of the sulfur cathode plus the easy fabrication of such a functional interlayer bring feasible Li−S batteries for practical applications one step closer.

Rapid detection of pathogenic bacteria present in patient samples is of utmost importance for the clinical management of bacterial‐induced diseases. Herein, we describe an efficient and direct electrochemical approach for the detection of 2‐heptyl‐3‐hydroxy‐4‐quinolone (PQS), 2‐heptyl‐4‐hydroxyquinoline (HHQ), and pyocyanin (PYO) as a molecular signature of Pseudomonas aeruginosa (PA), a frequently infecting pathogen with high antibiotic resistance. The cationic surfactant hexadecyltrimethylammonium bromide (CTAB) enhances the effectiveness of an unmodified thin‐film boron‐doped diamond (BDD) electrode for the direct detection of PYO, HHQ, and PQS in bacterial cultures of PAO1 and PA14. Differential pulse voltammetry (DPV) is then used to monitor the production of these microbial metabolites in bacterial cultures of PAO1 over 10 h without any sample pretreatment. A proposed mechanism for the interaction of CTAB with bacteria cells is examined by zeta (ζ) potential measurements. Furthermore, the detection method is successfully extended to a clinical fluid matrix and applied to PA spiked cystic fibrosis (CF) sputum samples.
