Spotted fever group Rickettsia (SFGR) infections remain largely under-investigated as causative agents of acute undifferentiated febrile illness (AUFI) in resource-limited settings. Few studies are available on the prevalence of SFGR infections in India, especially in eastern India. In a cross-sectional study conducted in 192 hospitalized adult and paediatric patients with AUFI, the frequency of SFGR using sequential PCR targeting genes encoding citrate synthase gene (gltA), 17 kDa lipoprotein precursor antigen (17kDa), outer membrane proteins A and B (omp A & omp B) was 6.

Purpose: Vocational Training is integral to Skill India Mission 2015, which targets to mitigate youth unemployment. However, evidence reveals a significant number of unenrolled youths. Existing studies pinpoint the reasons for this decline in varied nations including India, but rarely they are specific to indigenous communities.

Article Synopsis
  • - The study discusses the creation of three indium complexes (1-3) using different chelating ligands (L1-L3), which were analyzed through multinuclear NMR and confirmed by single-crystal X-ray crystallography.
  • - Indium complex 1, when combined with phenylsilane and NaI, efficiently reduces nitroarenes into amines, achieving good yields.
  • - The reduction process is effective for nitroarenes with various functional groups under standard reaction conditions.

A Ni-catalyzed C-N bond activation of 2-pyridylpyridone and 1-(9-alkyl 9-purin-6-yl)pyridin-2(1)-one and coupling with arylboronic acid have been achieved. A unique feature of this reaction is the strategic activation of the bridging C-N bond and replacement of the pyridone unit with aryl groups using nickel catalyzed Suzuki-Miyaura coupling. This provides an exciting new tool to build C-C bonds in the place of pyridones.

Herein, we report the synthesis of β-aminoketones by oxidative coupling of allyl alcohols at room temperature using a pyrazole based palladacycle and BINOL-phosphoric acid system. This method avoids the use of any base, external oxidant, and additive. The reaction of -anisidine and 1-penten-3-ol under the optimized conditions using isolated palladacycle-BINOL-phosphoric acid produced the desired product in 24 h, which suggests that the active species involved in this reaction is the palladacycle-BINOL-phosphoric acid.
