GC-MS analysis and antifungal activity of acetone extract of Conocephalum conicum (L) Underw (Liverwort) against aflatoxins producing fungi
Aflatoxins produced by Aspergillus are one of the extremely potent toxins of fungal origin that create serious health hazards in plants, animals and humans. The present study aims to search for a reliable and eco-friendly biocontrol of aspergillus by validating the use of some traditionally used bryophytes applying standard antifungal assays. Three bryophytes were collected from different altitudes (213-2100 m) of Western Himalaya. Crude organic extracts (methanol/ethanol or acetone) of three bryophytes viz. Conocephalum conicum (L.) Dumort., Marchantia papillata Raddi and Rhynchostegium vagans A. Jaeger were used for the control of Aspergillus flavus and A. parasiticus through food poisoned technique. The min. inhibitory concentration (MIC) and min. fungicidal concentration (MFC) was determined by micro broth dilution methods. Out of different crude organic extracts, acetone extract of Conocephalum conicum collected from Mukteshwar (altitude 2100 m) showed the highest percent inhibition (75±0.57-76±0.57%) with the lowest MFC (7.81μg/mL) against A. flavus and A. parasiticus which was compared with an antibiotic, fluconazole. The Gas Chromatog.-Mass Spectroscopy (GC-MS) anal. of the acetone extract of C. conicum revealed the presence of 30 major compounds out of which, riccardin C was found as a biomarker compound The scanning electron microscopic studies revealed the structural anomalies in the treated Aspergillus sp. which confirms the fungicidal potential of C. conicum against Aspergillus sp.

Convergent Route to β-Amino Acids and to β-Heteroarylethylamines: An Unexpected Vinylation Reaction
Various protected β²-amino acids can be prepared by radical addition of β-phthalimido-α-xanthyl propionic acid, both as the free acid or as the Et ester. Successive radical additions provide access to more complex structures. In the case of the free acid, addition to certain heteroaromatics leads directly to β-heteroarylethylamines through spontaneous decarboxylation of the intermediate adduct. Forcing the decarboxylation in some cases generated a vinyl group by decarboxylative elimination of the phthalimido group.

Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.

The effect of weathering on per- and polyfluoroalkyl substances (PFASs) from durable water repellent (DWR) clothing
To assess the effects of weathering on per- and polyfluoroalkyl substances (PFASs) from durable water repellent (DWR) clothing, thirteen com. textile samples were exposed to elevated ultra violet (UV) radiation, humidity, and temperature in an aging device for 300 h, which mimics the lifespan of outdoor clothing. Before and after aging, the textile samples were extracted and analyzed for the ionic PFASs (perfluoroalkyl acids (PFAAs), perfluorooctane sulfonamide (FOSA)) and volatile PFASs (fluorotelomer alcs. (FTOHs), acrylates (FTACs) and methacrylates (FTMACs)). Results showed that weathering can have an effect on PFASs used in DWR of outdoor clothing, both on the PFAS profile and on the measured concentrations In most weathered samples the PFAA concentrations increased by 5- to more than 100-fold, while PFAAs not detected in the original textiles were detected in the weathered samples. DWR chemistries are based on side-chain fluorinated polymers. A possible explanation for the increase in concentration of the PFAAs is hydrolysis of the fluorotelomer based polymers (FTPs), or degradation of the FTOHs, which are used in the manufacturing of the FTPs. The concentrations of volatile PFASs also increased, by a factor up to 20. Suggested explanations are the degradation of the DWR polymers, making non-extractable fluorines extractable, or the transformation or degradation of unknown precursors. Further research is needed to unravel the details of these processes and to determine the transformation routes. This study shows that setting maximum tolerance limits only for a few individual PFASs is not sufficient to control these harmful substances in outdoor clothing.

Highly Enantioselective, Hydrogen-Bond-Donor Catalyzed Additions to Oxetanes
A precisely designed chiral squaramide derivative is shown to promote the highly enantioselective addition of trimethylsilyl bromide (TMSBr) to a broad variety of 3-substituted and 3,3-disubstituted oxetanes. The reaction provides direct and general access to synthetically valuable 1,3-bromohydrin building blocks from easily accessed achiral precursors. The products are readily elaborated both by nucleophilic substitution and through transition-metal-catalyzed cross-coupling reactions. The enantioselective catalytic oxetane ring opening was employed as part of a three-step, gram-scale synthesis of pretomanid, a recently approved medication for the treatment of multidrug-resistant tuberculosis. Heavy-atom kinetic isotope effect (KIE) studies are consistent with enantiodetermining delivery of bromide from the H-bond-donor (HBD) catalyst to the activated oxetane. While the nucleophilicity of the bromide ion is expected to be attenuated by association to the HBD, overall rate acceleration is achieved by enhancement of Lewis acidity of the TMSBr reagent through anion abstraction.

Evolution of texture and strain in Sn coating with Cr addition and its effect on the coating corrosion behavior
Sn-Cr coatings with different amounts of Cr (∼1.3-5.5 wt%) were electrodeposited over mild steel substrate. Addition of Cr altered the coating morphol. from less compact and columnar for pristine Sn coating to relatively more compact and globular for Sn-Cr coatings. Incorporation of Cr led to reduction in crystallite sizes, increase in coating strain, and enhancement in Sn crystal growth along {011} and {112} planes. Microstructural characterization revealed the presence of Cr at the grain boundaries and formation of Sn and Sn-Cr grains in the coating microstructure. Corrosion measurements conducted using the Tafel polarization and electrochem. impedance spectroscopy revealed that incorporation of minor amounts of Cr leads to significant enhancement in the corrosion resistance property of the coatings when compared to the pristine Sn coating. When compared to the pristine Sn coating, the Sn-1.3 wt% Cr coating exhibited a 40% reduction in the corrosion c.d. value. The corrosion resistance properties however deteriorated for Sn-Cr coatings with higher Cr content (3.3 and 5.4 wt%). Reduction in the corrosion rate for lower Cr additions was attributed to enhancement in the grain boundary fraction and segregation of Cr to the grain boundaries. Enhancement in the corrosion rate for higher Cr addition was attributed mainly to increase in the coating strain.

Age-Dependent Decrease in Hepatic Geranylgeranoic Acid Content in C3H/HeN Mice and Its Oral Supplementation Prevents Spontaneous Hepatoma
Geranylgeranoic acid (GGA) has been developed as a preventive agent against second primary hepatoma. Recently, GGA was reported to induce cell death in human hepatoma cells via TLR4-mediated pyroptosis. We have reported that GGA is enzymically biosynthesized from mevalonic acid in human hepatoma-derived cells and that endogenous GGA is found in most organs of rats. In addition, we found that upregulation of endogenous GGA levels by zaragozic acid A (ZAA) induced cell death in human hepatoma-derived cells. Therefore, we investigated the age-related changes in hepatic GGA and the possibility of suppressing hepatocarcinogenesis by GGA supplementation using male C3H/HeN mice that spontaneously develop hepatoma. We measured endogenous GGA and mRNA of monoamine oxidase (BMAOB), a key enzyme of GGA biosynthesis, in the liver of male C3H/HeN mice aged 6-93 wk. We also tried suppressing spontaneous hepatocarcinogenesis by a single administration of GGA to C3H/HeN mice. Hepatic GGA content and Maob mRNA expression level age-dependently decreased in male C3H/HeN mice; some of which produced spontaneous hepatoma in 2 years. A single oral administration of GGA at 11 mo of age significantly prevented hepatoma in terms of the number and weight of tumors per mouse at 24 mo. Oral supplementation with GGA or geranylgeraniol significantly increased endogenous hepatic GGA contents dose-dependently; and ZAA dramatically upregulated hepatic GGA. In this study; we found an age-dependent decrease in hepatic endogenous GGA in male C3H/HeN mice and efficient prevention of spontaneous hepatoma by a single administration of GGA at 11 mo of age.

Targeted Single-Cell RNA and DNA Sequencing With Fluorescence-Activated Droplet Merger
Analyzing every cell in a diverse sample provides insight into population-level heterogeneity, but abundant cell types dominate the anal. and rarer populations are scarcely represented in the data. To focus on specific cell types, the current paradigm is to phys. isolate subsets of interest prior to anal.; however, it remains difficult to isolate and then single-cell sequence such populations because of compounding losses. Here, we describe an alternative approach that selectively merges cells with reagents to achieve enzymic reactions without having to phys. isolate cells. We apply this technique to perform single-cell transcriptome and genome sequencing of specific cell subsets. Our method for analyzing heterogeneous populations obviates the need for pre- or post-enrichment and simplifies single-cell workflows, making it useful for other applications in single-cell biol., combinatorial chem. synthesis, and drug screening.
