Article Abstract
The mechanisms of action of phosphine are diverse and include neurotoxicity, metabolic inhibition, and oxidative stress; however, its efficacy at low temperatures is unclear. : Comparative metabolomics is suitable for investigating the response of the spotted-wing fly to exposure toward a combination of cold stimuli and fumigant PH. : Under this combined exposure, 52 metabolites exhibiting significant differences in stress were identified and their physiological roles were analyzed in the metabolic pathway. Most metabolites were involved in amino acids, TCA cycle, and nucleic acids. In addition, the alteration levels of cell membrane lipids, such as glycerophospholipids, sphingolipids, and glycerolipids, clearly showed changes in the combined treatment compared to PH and low temperatures alone. Aconitic acid, a component of the TCA cycle, was completely inhibited by the combined treatment. : These results suggest that treatment-specific indicators could be useful biomarkers to indicate the synergistic effects of PH and low temperature on energy metabolism.

Natural Agents Modulating Ferroptosis in Cancer: Molecular Pathways and Therapeutic Perspectives.

Ferroptosis, a controlled cell death influenced by iron-dependent lipid peroxidation, presents potential therapeutic targets for cancer treatment due to its unique molecular pathways and potential drug resistance. Natural compounds, such as polyphenols, flavonoids, terpenoids and alkaloids, can influence ferroptosis via important signalling pathways, such as Nrf2/Keap1, p53, and GPX4. These are promising for combinational therapy due to their ability to cause ferroptotic death in cancer cells, exhibit tumour-specific selectivity and reduce systemic toxicity.

Objective: SURMOUNT-MAINTAIN aims to evaluate the efficacy and safety of reducing the tirzepatide dose and/or continuing the maximum tolerated dose (MTD) versus placebo in maintaining body weight (BW) reduction achieved with tirzepatide MTD.
Methods: This Phase 3b, multicenter, randomized, parallel-arm, double-blinded, placebo-controlled, 52-week clinical trial is in progress comparing treatment with once weekly tirzepatide (5 mg and/or MTD of 15 mg or 10 mg) versus placebo in achieving BW reduction maintenance from the initial 60-week open-label weight-loss period on tirzepatide MTD, in adults with obesity (BMI ≥ 30 kg/m or ≥ 27 kg/m with ≥ 1 obesity-related comorbidity, excluding type 2 diabetes). The primary endpoint is percent maintenance of BW reduction achieved during the weight-loss period at Week 112 among those who reached a BW plateau (i.

Background: Hyperthermia (HT), while a cancer treatment approach, isn't always effective alone. Therefore, identifying hyperthermia enhancers is crucial. We demonstrated that Mito-TEMPO ([2-[(1-Hydroxy-2,2,6,6-tetramethylpiperidin-4-yl) amino]-2-oxoethyl]-triphenylphosphanium, MT) acts as a potent thermosensitizer, promoting cell death in human cervical cancer (HeLa) cells.

Essential oils (EOs) are a promising alternative to conventional pesticides, but some challenges like high volatility, poor water solubility, and rapid degradation limit their use in Integrated Pest Management (IPM). To overcome these limitations, this study aimed to develop garlic, eucalyptus, and clove EO-based nano-emulsions (EO-NEs) in a bait treatment format through the high-pressure microfluidization technique and investigated the biological activities against Ceratitis capitata. In addition, the adverse effects of the most promising nano-emulsion were evaluated towards a non-target parasitoid Anagaspis daci.

Levofloxacin (LVFX)-associated seizures are thought to arise from disrupted excitatory-inhibitory balance, but the underlying synaptic mechanisms remain unclear. This study investigated how LVFX alters both glutamatergic and GABAergic transmission to promote neuronal hyperexcitability. We combined in vitro and in vivo approaches using primary cortical neurons treated with LVFX and adult rats administered LVFX.
