Darobactin A is a ribosomally synthesized, post-translationally modified peptide (RiPP) with potent and broad-spectrum anti-Gram-negative antibiotic activity. The structure of darobactin characterized by an ether C–C crosslinking. However, the specific mechanism crosslink formation, especially crosslink, remains elusive. Here, using in vitro enzyme assays, we demonstrate that both crosslinks are formed DarE radical S-adenosylmethionine (SAM) O2-dependent manner. relevance observed activity...
Medicinal mushroom Ganoderma lucidum is one of the most esteemed natural products that have been used in traditional Chinese medicine. In this article, we demonstrate G. triterpene extract (GLT) suppresses proliferation human colon cancer cells HT-29 and inhibits tumor growth a xenograft model cancer. These effects GLT are associated with cell cycle arrest at G0/G1 induction programmed death Type II-autophagy cells. Here, show induces formation autophagic vacuoles upregulates expression...
Essential oils were extracted from the culm and leaf of Cymbopogon citratus collected different regions Vietnam analyzed using GC/MS. The results showed that citral is major component accounting for 61.20%–76.46% essential oils. content was higher in oil obtained than lemongrass all regions. In particular, camphene, valerianol, epi- α -muurolol can be used to differentiate originating leaves versus culms. cytotoxic effects on various lung cancer cell lines evaluated present study. All...
Non-invasive approaches for monitoring therapy processes in cancer patients at late stages is truly needed.
Eurycoma longifolia is an herbal medicinal plant popularly used in Southeast Asian countries. In the present study, we show that 7-methoxy-(9H-β-carbolin-1-il)-(E)-1-propenoic acid (7-MCPA), a β-carboline alkaloid isolated from E. longifolia, exerted anti-inflammatory effects by activating nuclear factor-E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. 7-MCPA inhibited lipopolysaccharide (LPS)-induced production of nitric oxide (NO), prostaglandin E2 (PGE2 ), and interleukin-6...
ContextThe Piper species was studied several potential properties such as anti-tumor, anti-inflammatory and antioxidant activity. However, the specific activity of extract from fruits P. longum L. has not been investigated.ObjectivesOur study want to examine effects fruit methanolic extracts (PLE) on lipopolysachharide (LPS)-stimulated RAW 264.7 murine macrophages understand mechanism this effect.MethodThis examined chemical profiling PLE by LC-HRMS analysis measured presence nitric oxide...
Two new flavonoid glycosides, (1, 2), and eleven known compounds, (3—13), were isolated from a 70% EtOH extract of the leaves Chromolaena odorata (Asteraceae). Their structures elucidated by 1D 2D NMR spectroscopic interpretation as well chemical studies. The newly compounds tested in vitro for their cytotoxic activities against LLC HL-60 cancer cell lines. Compound 1 showed cytotoxicity lines with IC50 values 28.2 11.6 μM, respectively. 2 exhibited significant activity inhibition value 10.8 μM.

White turmeric is a rhizome plant that contains essential oils and many secondary metabolites having medicinal effects. In order to improve yield oil content, this study investigated the response of growth regulators stages white plants grown from mother tubers in an experimental garden. After 2 weeks treatment, rhizomes were measured for fresh dry weight, length, sugar starch content. Rhizome yield, number per content after 24 treatment. The results showed weight as well at resting shoot...
The study aims to evaluate the environmental parameters and growth rate of snu-bnose pompano cultured in “In Pond Raceway System - IPRS”. Fingerlings 5-6 cm length were stocked at a density 72 fish/m3 220 m3 raceway (22 m x 5 width 2 depth) placed 10,500 m2 pond (125 84 width) 2.5 depth. Fish fed by commercial pellet food (slow sinking food) contented 45-48% protein 7 am (30-40%) 4 pm (60-70%) with feeding 5-7% per day for small fish 2-5% bigger size. After months culture, achieved an...
Background Urinary tract infections (UTIs) are common globally, and developing increased antibiotic resistance. Despite being the diagnostic “gold standard,” urine culture is limited by slow results a high rate of false negative findings, leading to treatment delays, higher costs, overuse empirical antibiotics. Our study aims develop rapid reliable model predict clinical outcomes. Methods From January 1st October 31st, 2023, we enrolled patients with symptoms suggesting UTI from Outpatient...

Abstract. The constellation of Earth-observing satellites has now produced atmospheric greenhouse gas concentration estimates covering a period several years. Their global coverage is providing additional information on the carbon cycle. These products can be combined with complex inversion systems to infer magnitude sources and sinks around globe. Multiple factors, including transport model satellite product aggregation method, impact such flux estimates. Analysis variance (ANOVA)...
This study investigates the optimal conditions to enrich phenolic content of extract from Pandanus amaryllifolius leaves and evaluates bioactivities this enrichment. The enrichment was prepared under optimized using response surface methodology (RSM) with Box–Behnken design. antioxidant properties were assessed DPPH hydroxyl radical scavenging assays, while NO production inhibition measured in LPS‐stimulated RAW 264.7 macrophage cells. Results indicated that showed potent activity comparable...
