Hermit Treutler's Jerusalem Balsam

This paper describes research about a historical bottle found in the Polish town of Skarszewy in 2004. Upon discovery, the find was labeled "In Nazareth Aechter Jerusalemer Balsam im goldnen Engel", sealed and ⅓ filled with liquid. The Jerusalem Balsam mentioned on the label was a popular medicament in Europe in the 18th century. From 1719 it was produced by Father Antonio Menzani da Cuna in the Franciscan Pharmacy at the convent of Saint Savior in Jerusalem. In the 19th century, the Balsam became extremely popular in Silesia thanks to the hermit Johannes Treutler from Mariańska Hill near Kłodzko. It's fame spread north to Prussia and south to Bohemia (Czechia). After the hermit's death, the license for production was obtained by the owner of the Mohren-Apotheke pharmacy, but he had to deal with unfair competition from other pharmacies counterfeiting the Balsam. An attempt was made to determine where the found bottle came from. In the course of the research, it was found that the medicine certainly does not come from authorized production sources, as evidenced by accurate label comparisons

Contemporary analytical techniques reveal the secret composition of a 19th century Jerusalem Balsam

In 1719, Antonio Menzani di Cuna from the Saint Savior monastery published an alcoholic extract formula made from plant and herb resins under the name Jerusalem Balsam. The Balsam gained high popularity due to its remedial benefits. At the end of the 19 th century, Jerusalem Balsam produced by the hermit Johannes Treutler was found to be particularly popular. We analysed a sample of a valuable find coming from the last decade of the 19 th century, making it probably the oldest surviving Jerusalem Balsam in the world. The purpose of this work was to investigate the composition of the historical sample and to try to determine the origin of its components. This was achieved by comparing the profile of volatile compounds extracted from the balsam using HS-SPME technique with the profile characteristic for plant resins as classic ingredients of the Johannes Treutler formula. The use of two chromatographic columns of different polarity, as well as the transformation of the polar components of the sample into TMS derivatives, allowed to obtain new information on the historical composition of the Balsam. Also, it can be stated with high probability that plant resins were indeed used in the production of the Balsam as referred to in the original recipe of Johannes Treutler. We also discuss challenges in determining the original composition of the Balsam

A multinuclear NMR study of six forms of AlPO-34:structure and motional broadening

We report a study of the CHA-type aluminophosphate AlPO-34, prepared with six different structure-directing agents (SDAs): piperidine (pip), morpholine (mor), pyridine (pyr), 1,4,8,11-tetraazacyclotetradecane (cyclam), 1,3 dimethylimidazolium (dmim) chloride and 1-ethyl-3-methylimidazolium (emim) bromide. Using a combination of solid-state NMR spectroscopy, periodic density functional theory (DFT) calculations and synchrotron X-ray diffraction, we show that, even in crystallographically well-ordered materials such as AlPO-34 with dmim as the SDA, local disorder may be present. For such disordered structures, where it is challenging to use DFT to assign NMR spectra, we show that the 31P isotropic chemical shift can be predicted accurately using the mean P-O bond length and P-O-Al bond angle, in an extension of previous work. Variable-temperature 27Al NMR reveals the presence of microsecond-timescale dynamics in all forms of AlPO- 34, with two different motional regimes observed, depending on whether structural H2O is also present. H2O is detected in AlPO-34 prepared with mor as the SDA, although this material was previously reported as anhydrous, suggesting that this form of AlPO-34 may be hygroscopic despite the presence of the SDAs within the pores

Solid-State Dynamics in the closo-Carboranes:A (11)B MAS NMR and Molecular Dynamics Study

This work explores the dynamic behaviour of the three closo-carborane isomers (formula C2B10H12) using modern solid-state magic angle spinning (MAS) NMR techniques and relates the experimental measurements to theoretical results obtained using molecular dynamics simulations. At high temperatures and at B0 = 9.4 T, the 11B MAS linewidths are narrow (40-90 Hz) for the three isomers. The rotational correlation times (tauc) calculated by molecular dynamics are on the picosecond timescale, showing a quasi-isotropic rotation at these temperatures, typical for liquid systems. For all three isomers, the values of the 11B spin-lattice relaxation times (T1) show discontinuities as the temperature is decreased, confirming the phase changes reported in the literature. At low temperatures, the 11B MAS spectra of all three isomers exhibit much broader lines. The simulations showed that the molecular reorientation was anisotropic around different symmetry axes for each isomer, and this was supported by the values of the reduced quadrupolar parameter PQeff derived from “dynamic shift” measurements using 11B MQMAS NMR spectroscopy. The behaviour of PQeff as a function of temperature for para-carborane suggests that molecular reorientation is about the C5 symmetry axis of the molecule at low temperatures and this was supported by the molecular dynamics simulations

Chemical composition of Desulfovibrio desulfuricans lipid A

Lipopolysaccharides also called endotoxins are an integral component of the outer membrane of Gram-negative bacteria. When released from the bacterial surface, they interact with a host immune system, triggering excessive inflammatory response. Lipid A is the biologically most active part of endotoxin, and its activity is modulated by the quantity, quality and arrangement of its fatty acids. Desulfovibrio desulfuricans is sulfate-reducing, Gram-negative bacterium that is supposed to be opportunistic pathogens of humans and animals. In the present study, chemical composition of lipid A from various strains of D. desulfuricans was analyzed by gas chromatography/mass spectrometry. It was found that the fatty acid component of the lipid A contains dodecanoic, tetradecanoic, 3-hydroxytetradecanoic and hexadecanoic acids, and its carbohydrate core is composed of glucosamine. The analysis of 3-acyloxyacyl residue of the lipid A revealed the presence of amide-bound 3-(dodecanoyloxy)tetradecanoic and 3-(hexadecanoyloxy)tetradecanoic acids and ester-bound 3-(tetradecanoyloxy)tetradecanoic acid. It was concluded that both fatty acid and 3-acyloxyacyl residue profiles of the lipid A from the studied bacteria were similar to those of E. coli and S.enterica

\u3ci\u3eSalmonella enterica\u3c/i\u3e serovar Typhimurium-infected pigs with different shedding levels exhibit distinct clinical, peripheral cytokine and transcriptomic immune response phenotypes

Foodborne salmonellosis costs the US $2.7 billion/year, including$100.0 million in annual losses to pork producers. Pigs colonized with Salmonella are usually asymptomatic with varied severity and duration of fecal shedding. Thus, understanding the responses that result in less shedding may provide a mechanism for control. Fifty-four pigs were inoculated with Salmonella enterica serovar Typhimurium (ST) and clinical signs, fecal ST shedding, growth performance, peripheral cytokines and whole blood gene expression were measured. Persistently shedding (PS) pigs had longer pyrexia and elevated serum IL-1b, TNF-a and IFN-g compared with low shedding (LS) pigs, while LS pigs had brief pyrexia, less shedding that decreased more rapidly and greater serum CXCL8 than PS pigs. The PS pigs up-regulated genes involved with the STAT1, IFNB1 and IFN-g networks on d 2, while up-regulation of genes involved in immune response regulation were only detected in LS pigs. This is the first study to examine host responses to ST infection at a clinical, performance, cytokine and transcriptomic level. The results indicated that pigs with different shedding outcomes developed distinct immune responses within the first 2 d of ST infection, and elucidated alternative mechanisms that could be targeted to reduce Salmonella shedding and spread
