A new method based on time-resolved X-ray diffraction is proposed in order to measure the elastic strain and stress during ultrasonic fatigue loading experiments. Pure Cu was chosen as an example material for the experiments using a 20 kHz ultrasonic fatigue machine mounted on the six-circle diffractometer available at the DiffAbs beamline on the SOLEIL synchrotron facility in France. A two-dimensional hybrid pixel X-ray detector (XPAD3.2) was triggered by the strain gage signal in a synchronous data acquisition scheme (pump–probe-like). The method enables studying loading cycles with a period of 50 µs, achieving a temporal resolution of 1 µs. This allows a precise reconstruction of the diffraction patterns during the loading cycles. From the diffraction patterns, the position of the peaks, their shifts and their respective broadening can be deduced. The diffraction peak shift allows the elastic lattice strain to be estimated with a resolution of ∼10−5. Stress is calculated by the self-consistent scale-transition model through which the elastic response of the material is estimated. The amplitudes of the cyclic stresses range from 40 to 120 MPa and vary linearly with respect to the displacement applied by the ultrasonic machine. Moreover, the experimental results highlight an increase of the diffraction peak broadening with the number of applied cycles.

The title compound, C4H9N5O2+·SO42−·H2O, is the monohydrate of the commercially available compound `C4H7N5O·H2SO4·xH2O'. It is obtained by reprecipitation of C4H7N5O·H2SO4·xH2O from dilute sodium hydroxide solution with dilute sulfuric acid. The crystal structure of anhydrous 2,4,5-tri­amino-1,6-di­hydro­pyrimidin-6-one sulfate is known, although called by the authors 5-amminium-6-amino-isocytosinium sulfate [Bieri et al. (1993). Private communication (refcode HACDEU). CCDC, Cambridge, England]. In the structure, the sulfate group is deprotonated, whereas one of the amino groups is protonated (R2C—NH3+) and one is rearranged to a protonated imine group (R2C=NH2+). This arrangement is very similar to the known crystal structure of the anhydrate. Several tautomeric forms of the investigated mol­ecule are possible, which leads to questionable proton attributions. The measured data allowed the location of all hydrogen atoms from the residual electron density. In the crystal, ions and water mol­ecules are linked into a three-dimensional network by N—H⋯O and O—H⋯O hydrogen bonds.

The asymmetric unit of the title salt, 2C12H28N+·SO42−·3H2O, contains two n-do­decyl­ammonium cations, one sulfate anion and three water mol­ecules. In the crystal, N—H⋯O hydrogen bonds link the cations and anions into layers parallel to (100). These layers are further connected through O—H⋯O hydrogen-bonding inter­actions involving the sulfate ions and the isolated water mol­ecules. The three-dimensional structure can also be considered as the superposition of thin inorganic layers of SO42− anions and thick layers of alkyl­ammonium cations perpendicular to the c axis.

The title mol­ecular salt, C9H12N3O2S+·HSO4−, was obtained through the protonation of the azomethine N atom in a sulfuric acid medium. The crystal com­prises two entities, a thio­semicarbazide cation and a hydrogen sulfate anion. The cation is essentially planar and is further stabilized by a strong intra­molecular O—H⋯N hydrogen bond. In the crystal, a three-dimensional network is established through O—H⋯O and N—H⋯O hydrogen bonds. A weak intermolecular C—H⋯O hydrogen bond is also observed. The hydrogen sulfate anion exhibits disorder over two sets of sites and was modelled with refined occupancies of 0.501 (6) and 0.499 (6).

The solid-state structures of two cobalt–pyridine–sulfate compounds, namely catena-poly[[tetra­kis­(pyridine-κN)cobalt(II)]-μ-sulfato-κ2O:O'], [Co(SO4)(C5H5N)4]n, (1), and catena-poly[[tetra­kis­(pyridine-κN)cobalt(II)]-μ-sulfato-κ3O:O',O''-[bis­(pyridine-κN)cobalt(II)]-μ-sulfato-κ3O,O':O'']n, [Co2(SO4)2(C5H5N)6]n, (2), are reported. Compound (1) displays a polymeric structure, with infinite chains of CoII cations adopting octa­hedral N4O2 coordination environments that involve four pyridine ligands and two bridging sulfate ions. Compound (2) is also polymeric with infinite chains of CoII cations. The first Co center has an octa­hedral N4O2 coordination environment that involves four pyridine ligands and two bridging sulfate ligands. The second Co center has an octa­hedral N2O4 coordination environment that involves two pyridine ligands and two bridging sulfate ions that chelate the Co atom. The structure of (2) was refined as a two-component inversion twin.

SrS2O3·H2O was obtained from an aqueous solution of Na2S2O3 and Sr(NO3)2 and crystallizes in space group Poverline{1} with all atoms at general positions. The Sr2+ ion exhibits an [8 + 1] coordination defined by two terminal S and six O atoms of thio­sulfate ions, one of the latter at a longer distance, and by one O atom of a water mol­ecule. Two thio­sulfate anions act as bidentate, four as monodentate ligands. The structure consists of mainly ionically inter­acting layers lying parallel to the crystallographic ab plane. The layers are connected by O—H⋯S and O—H⋯O hydrogen bonds of moderate strength.

Single-particle electron cryo-microscopy (cryoEM) has undergone a `resolution revolution' that makes it possible to characterize megadalton (MDa) complexes at atomic resolution without crystals. To fully exploit the new opportunities in molecular microscopy, new procedures for the cloning, expression and purification of macromolecular complexes need to be explored. Macromolecular assemblies are often unstable, and invasive construct design or inadequate purification conditions and sample-preparation methods can result in disassembly or denaturation. The structure of the 2.6 MDa yeast fatty acid synthase (FAS) has been studied by electron microscopy since the 1960s. Here, a new, streamlined protocol for the rapid production of purified yeast FAS for structure determination by high-resolution cryoEM is reported. Together with a companion protocol for preparing cryoEM specimens on a hydrophilized graphene layer, the new protocol yielded a 3.1 Å resolution map of yeast FAS from 15 000 automatically picked particles within a day. The high map quality enabled a complete atomic model of an intact fungal FAS to be built.

The specification of organs, tissues and cell types results from cell fate restrictions enacted by nuclear transcription factors under the control of conserved signaling pathways. The progenitor epithelium of the Drosophila compound eye, the eye imaginal disc, is a premier model for the study of such processes. Early in development, apposing cells of the eye disc are established as either retinal progenitors or support cells of the peripodial epithelium (PE), in a process whose genetic and mechanistic determinants are poorly understood. We have identified Protein Phosphatase 2A (PP2A), and specifically a STRIPAK-PP2A complex that includes the scaffolding and substrate-specificity components Cka, Strip and SLMAP, as a critical player in the retina-PE fate choice. We show that these factors suppress ectopic retina formation in the presumptive PE and do so via the Hippo signaling axis. STRIPAK-PP2A negatively regulates Hpo kinase, and consequently its substrate Wts, to release the transcriptional co-activator Yki into the nucleus. Thus, a modular higher-order PP2A complex refines the activity of this general phosphatase to act in a precise specification of cell fate.

Over 32,000 people have died from the new coronavirus in the United Kingdom, according to the Office for National Statistics, marking the first time in the pandemic that it has led Europe in the number of deaths.

The country has surpassed Italy in COVID-19 deaths. The U.S. still leads the world in the highest number of coronavirus deaths; over 70,270 had died from the disease as of Tuesday.

The number of total deaths recorded in the U.K. is "higher than we would wish, I think is all I can say," Angela McLean, chief scientific adviser of Ministry of Defence said during the country's press briefing Tuesday.

McLean also emphasized that deaths in U.K. care homes have been steadily rising and said the trend was something the country "need[s] to get to grips with."

"I don't think we'll get a real verdict on how well countries have done until the pandemic is over," British Foreign Secretary Dominic Raab said Tuesday. "And particularly until we have comprehensive international data on all causes of mortality."

Since different countries collect and report coronavirus data using different methods, the comparisons between regions are not perfect. As more time passes and more tests are conducted and more data comes in, coronavirus death rates will become more precise.

The peak in deaths comes as other European countries, including Italy and Spain, are easing shelter-in-place restrictions, while U.K. Prime Minister Boris Johnson is expected to modify Britain's orders in the next week.

In an April 20 research note, Dawson James analyst Jason Kolbert wrote that results from Can-Fite BioPharma Ltd.'s (CANF:NYSE.MKT) Phase 2 trial of Namodenoson for nonalcoholic fatty liver disease with or without nonalcoholic steatohepatitis "look pretty good."

He added that "the consistency of the data from the studies (preclinical and clinical), should support business development interest."

Dawson James has a $9 per share target price on Can-Fite; the stock is currently trading at around $1.75 per share.

Kolbert recapped the study design and provided the results.

This purpose of this multicenter, randomized, double-blinded, placebo-controlled trial involving 60 patients was to determine dose efficacy and safety. Patients were treated twice a day with either 12.5 milligrams or 25 milligrams of oral Namodenoson or a placebo for 12 weeks.

The primary endpoint was effect on inflammation, measured by mean percent change from baseline in alanine transaminase blood levels and safety. The second endpoints included the percent change from baseline in liver fat, as determined by MRI proton density fat fraction.

In terms of safety, study participants tolerated Namodenoson at both doses, and no adverse events were reported. Otitis media occurred in two patients but was deemed to be unrelated to the drug. The four other events that occurred that were drug related were mild and self-limited.

Regarding efficacy of Namodenoson, Kolbert noted that "for a small Phase 2 exploratory study, there appears to be a significant efficacy signal."

Kolbert provided updates on other Can-Fite clinical trials.

The company's COVID-19 trial is now designed. Plans call for it to be randomized, open label, and double armed with Piclidenoson administered plus standard supportive care, compared to standard supportive care alone, in 40 hospitalized COVID-19-infected patients with moderate to severe symptomatic disease.

Patients are to be randomized at a 1:1 ratio to one of the trial arms and treated for up to four weeks. The primary efficacy measures will be time to resolution of viral shedding, time to resolution of clinical symptoms, respiratory function, need for ventilatory support and overall mortality.

Piclidenoson, Can-Fite's lead drug candidate, also is in Phase 3 in two indications: moderate to severe rheumatoid arthritis (the ACROBAT study) and moderate to severe plaque psoriasis (the COMFORT study). Enrollment for both trials is more halfway complete. In both, Piclidenoson "hold great promise as alternative therapies with what appears to be a more favorable side effects profile," Kolbert commented.

Dawson James has a Buy rating on Can-Fite BioPharma.
