A complex reaction mechanism of oxidation of the anti-tubercular prodrug isoniazid (isonicotinic hydrazide, INH) by [IrCl6]2− as a model for redox processes of such drugs in biological systems has been studied in aqueous solution as a function of pH between 0 and 8.5. Similar experiments have been performed with its isomer nicotinic hydrazide (NH). All reactions are overall second-order, first-ordA complex reaction mechanism of oxidation of the anti-tubercular prodrug isoniazid (isonicotinic hydrazide, INH) by [IrCl6]2− as a model for redox processes of such drugs in biological systems has been studied in aqueous solution as a function of pH between 0 and 8.5.

4-Alkenyl- and 4-acyloxazoles represent important substructures across a diverse array of bioactive molecules. Practical methods to synthesize these motifs are, therefore, of considerable interest. Here, we develop a novel domino process wherein a cycloisomerization is followed by a 1,2-rearrangement via an oxazolonium ion to yield 4-alkenyloxazoles from an abundant β-chloro-N-benzyl propargylamin

Popular Abstract in English Fungi are multi-cellular eukaryotic organisms which form thread-like filaments called hyphae. They form reproductive structures called sporocarp (also known as mushrooms). Most fungi are saproptrophs, feeding on dead or decaying material while many are also parasitic, feeding on living organisms. In addition, most vascular plants are always in symbiotic association withEctomycorrhizae is the dominant type of mycorrhiza found in association with tree roots in boreal and northern temperate forests. In this symbiosis, the fungal partner derives energy from photosynthates provided by the host trees and in return delivers soil-derived nutrients such as nitrogen (N). The majority of N in forest soils is embedded in recalcitrant organic matter–protein complexes. Ectomy

In a method and a mobile communications receiver for performing signal measurements, signal measurement data is received from at least one base station during at least part of a measurement period. Each measurement period comprises a number of non-equidistant snapshot measurement windows during which the receiver receives signal measurement data. At least one average signal strength value of the s

Depletion of onshore and shallow water reserves, in combination with new subsea technology, has made the petroleum industry advance into deeper water. However, new technology also brings new risks. Since most widely accepted standards and regulations are not directly aimed for subsea systems, new methods have to be developed. By developing a LOPA-model, which can be used specifically for subsea co

Den svenska skattelagens inkomstbegrepp bygger på att den beskattningsbara inkomsten motsvarar nettovärdet av en summa från vilken avdrag har gjorts. Avdrag ska göras för utgifter nödvändiga för att förvärva och bibehålla inkomster, samt för ränteutgifter och kapitalförluster. Sistnämnda ska dras av även om de inte är sådana utgifter, och intar således något av en särställning. Ränteavdragsrätten The Swedish income tax law’s definition of income is built on the concept of a net income from which a deduction has been made. Deductions shall be made for expenses that have been necessary for acquiring and maintaining income, and for interest expenses and capital losses. The last two should be deducted regardless if they are such expenses or not, and has therefore something of a unique position

Housing market in Punjab faces number of challenges related to supply, population growth, access to utilities, affordability, and consumer mortgages. In 2017, Punjab, Pakistan, experienced a total urban housing deficit of about 2.3 million units. Due to the Punjab's low supply of affordable housing, home ownership is uneven, with the majority of owners being concentrated in the highest-income

This study investigates if there are any advantages in increasing foreign direct investments for members of the Association of South Asian Nations (ASEAN) regional integration area. The study explains the effect that regional integration, preferential trade agreements and free trade areas have on attracting foreign direct investments. Different aspects of regional integration are used to explain w

SynopsisProtonolysis of the title compounds involves rate-determining proton transfer to the substrate. Subsequent isomerization is dissociative. Activation volumes for the two processes have opposite signs. A new kinetic β-hydrogen accelerating effect for isomerization favoring the fluxionality of a T-shaped 14-electron intermediate is reported.AbstractProtonolysis of the complexes cis-[PtR2(PEt3

Introduction and aim: In SPECT imaging, the finite spatial resolution of the imaging system leads to a blurring of the reconstructed image. Consequently, counts originating from each point in the source distribution will be spread out over a volume in the reconstructed image, leading to spill-over of counts between different structures and distortion of the apparent activity concentration.
