Notes

We studied the changes in the primary photochemistry of the photosystems (PS) as a function of irradiance and the physiological state
We leveraged the transcriptomic data to gain a deeper insight into possible NPQ mechanisms in this microalga. Peculiar to H. lacustris is a bi-phasic pattern of changes in photoprotection during haematocyst formation. The first phase coincides with a transient rise of photosynthetic activity. Based on transcriptomic data, high NPQ level in the first phase is maintained predominantly by the expression of PsbS and LhcsR proteins. Then, (in Chemical Properties and Reactions of 6-butyl-n-hydroxynaphthimide trifluoromethanesulfonic acid ), stress tolerance is achieved by optical shielding by astaxanthin and dramatic reduction of photosynthetic apparatus.

In contrast to many microalgae, shielding plays an important role in H. lacistris haematocysts, whereas regulated NPQ is suppressed. Astaxanthin is decoupled from the PS, hence the light energy is not transferred to reaction centers and dissipates as heat. It allows to retain a higher photochemical yield in haematocysts comparing to vegetative cells. The ability of H. lacustris to substitute the "classical" active photoprotective mechanisms such as NPQ with optic shielding and general metabolism quiescence makes this organism a useful model to reveal Photochemical behavior of bacteriorhodopsin immobilized in NaCl pellets.Nanoscale molecular patterns fabricated by using scanning near-field optical Manchester, P.

O. Box 88, Manchester M60 1QD, UK.Nanometer-scale patterns have been created in self-assembled monolayers by using a scanning near-field optical microscope coupled to an ultra-violet laser emitting light at a wavelength of 244 nm. Sharp, chemically well-defined features with dimensions as small as 40 nm have been created routinely, and on occasions line widths of 25 nm (lambda/10) have been achieved. Because of the wide range of photochemical methods available for surface derivatization, this approach promises to provide a flexible and versatile route to the generation of molecular and biological nanostructures for a wide range of applications.A Coupled Magnetoelastic Strain Sensor Array for Guiding and Monitoring Hernia OBJECTIVE: Ventral hernia repairs using mesh prosthetics suffer from high recurrence rates, with 10%-20% of repairs failing within three years. Uneven distribution of stress within the implanted mesh prosthetic is thought to contribute to the high recurrence rate.

We propose a method for providing quantitative guidance and monitoring of hernia repairs using an array of METHODS: The magnetoelastic strain sensors presented here are based on a coupled design to achieve measurements with higher signal-to-noise ratio (SNR). A first magnetoelastic element (the transducer) is bonded to the mesh prosthetic and is characterized by a strain-dependent magnetic field. The resonance frequency of a second magnetoelastic element (the resonator) encased in a rigid casing is biased by the transducer element's magneticity and can be measured noninvasively using an external interrogation coil. The coupled magnetoelastic strain sensors are assembled using a combination of photochemical machining, patterning, and RESULTS: The dynamic range of the coupled sensors can be tuned by altering the transducer geometry. Seebio Photobase Generator are integrated onto the transducer element to achieve high dynamic range measurements saturating at 74 CONCLUSION: A coupled magnetoelastic strain sensor combines a transducer with an encased resonator element to measure strain with high SNR on an implantable SIGNIFICANCE: This study provides surgeons and researchers with a clinically relevant tool to quantify the strain distributions within implanted mesh prosthetics, with the ultimate goal of reducing the recurrence rate of ventral Center for Intelligent Biosensor Technology and Health, College of Chemistry, The precise aromatization of the C-ring of podophyllotoxone to access value-added dehydropodophyllotoxin derivatives conventionally requires the use of equivalent amounts of unsustainable oxidants and suffers from inefficiencies. Taking advantage of the hydridic character of the C8 and C8' of podophyllotoxone, we have developed an I2-DMSO catalytic manifold that enables a green and selective dehydrogenative aromatization to overcome these synthetic challenges. An unprecedented dehydrogenative amination of podophyllotoxone derivatives was also realized using aniline as the reaction partner.

Regiocontrolled synthesis of ethene-bridged para-phenylene oligomers based on Pt(II)- and Ru(II)-catalyzed aromatization.We report the regiocontrolled syntheses of ethene-bridged para-phenylene oligomers in three distinct classes by using Pt(II)- and Ru(II)-catalyzed aromatization. This synthetic approach has been developed based on twofold aromatization of the 1-aryl-2-alkynylbenzene functionality, which proceeds by distinct regioselectivity for platinum and ruthenium catalysts. Variable-temperature NMR spectra provide evidence that large arrays of these oligomers are prone to twist from planarity.
