We demonstrated the energy scaling of high-order harmonics using a self-guided beam
under the phase-matched condition. By adjusting the argon gas density and pump laser …

Previous randomized controlled trials (RCTs) and meta-analyses evaluated the efficacy and
safety of adjunctive corticosteroids for community-acquired pneumonia (CAP). However, the …

It is unclear whether in the treatment of community‐acquired pneumonia (CAP) beta‐lactam
plus macrolide antibiotics lead to better survival than beta‐lactam alone. We report a …

Optical resolution of(±)-2-chloroacetylaminotridecanoic acid with amino acylase gave (S)-2-aminotridecanoic
add, which was converted into highly optically pure (S)-5-hexadecanolide (…

1-Alkenyl cyclopropyl ketones, when activated by cation-stabilizing substituents at the ring
carbon or at the terminal carbon of the enone moiety, undergo polyphosphoric acid-catalyzed …

Both (5S, 6R)-(+)-and (5R, 6S)-(−)-6-acetoxy-5-hexadecanolide, the oviposition attractant
pheromone of the mosquito Culex pipiens fatigans, were synthesized employing the …

All of the four possible stereoisomers (ca. 95% ee) of 5-hydroxy-4-decanolide (L-factors), the
proposed autoregulator from Streptomyces griseus, were synthesized from (±)-1-octen-3-ol …

(2S, 3S)-2, 3-Octanediol and (S)-2-hydroxy-3-octanone, the pheromone of the grape borer,
were synthesized from (±)-1-octen-3-ol employing the Sharpless asymmetric epoxidation as …

A series of substituted 4-oxoquinoline-3-carboxylic acids having a methyl group at the 8-position
was prepared and tested for their antibacterial activity. 7-(trans-3-Amino-4-methyl-1-…

5,3,7-Dithiadiazocanes, 1,5,3,7-diselenadiazocanes, and 1,5,3,7-ditelluradiazocanes were
prepared from a primary amine, formalin, and H 2 S, NaSeH, or NaTeH, respectively. …
