Glutamine metabolism is pivotal in cancer biology, profoundly influencing tumor growth, proliferation, and resistance to therapies. Cancer cells often exhibit an elevated dependence on glutamine for essential functions such as energy production, biosynthesis of macromolecules, and maintenance of redox balance. Moreover, altered glutamine metabolism can contribute to the formation of an immune-suppressive tumor microenvironment characterized by reduced immune cell infiltration and activity.

Pyroptosis is a critical pathological mechanism implicated in myocardial damage following myocardial infarction (MI), and the crosstalk between macrophages and pyroptotic cardiomyocytes presents a formidable challenge for anti-pyroptosis therapies of MI. However, as single-target pyroptosis inhibitors frequently fail to address this crosstalk, the efficacy of anti-pyroptosis treatment post-MI remains inadequate. Therefore, the exploration of more potent anti-pyroptosis approaches is imperative for improving outcomes in MI treatment, particularly in addressing the crosstalk between macrophages and pyroptotic cardiomyocytes.

The mechanical properties of nanoparticles play a crucial role in regulating nanobiointeractions, influencing processes such as blood circulation, tumor accumulation/penetration, and internalization into cancer cells. Consequently, they have a significant impact on drug delivery and therapeutic efficacy. However, it remains unclear whether and how macrophages alter their biological function in response to nanoparticle elasticity.

Article Synopsis
  • * UV222 and UV254 show similar effectiveness in inactivating E. coli, but UV222 treatment prevents reactivation by causing extensive damage to the bacteria's DNA and cell membrane.
  • * Overall, using UV222 for disinfection may be a better option for water treatment as it minimizes the chance of bacterial recovery after treatment.

This study presents the design of a Surface-enhanced Raman scattering (SERS) substrate, COF@Ag, for the sensitive detection of Amoxicillin (AMX) in lake water and honey. Furthermore, the study investigates the role of covalent organic frameworks (COFs) in SERS detection. The characterization results demonstrate the capability of COFs to efficiently enrich Ag nanoparticles (AgNPs), resulting in a more concentrated distribution of hotspots and an enhanced electromagnetic field on the substrate.

Article Synopsis
  • - The study investigates how well different oxidants—ozone (O), peroxymonosulfate (PMS), and hydrogen peroxide (HO)—can inactivate the MS2 coliphage virus in water, which is important for preventing viral disease spread.
  • - Results showed that to achieve a significant 4-log reduction in virus levels, all three oxidants needed specific doses and a contact time of 30 minutes, but ozone was the fastest, requiring only 0.5 minutes.
  • - In secondary effluent, all three oxidants effectively inactivated the virus and removed dissolved organic matter, but ozone was found to be the most efficient option overall for disinfection.

Transforming macrophages into the anti-inflammatory M2 phenotype could markedly strengthen inflammatory bowel disease (IBD) treatment, which is considered as a promising strategy. However, the high ferroptosis sensitivity of M2 macrophages, which decreases their activity, is a major stumbling block to this strategy. Therefore, promoting M2 polarization while simultaneously inhibiting ferroptosis to tackle this challenge is indispensable.

Repolarizing the tumor-associated macrophages (TAMs) towards the antitumoral M1-like phenotype has been a promising approach for cancer immunotherapy. However, the anti-cancer immune response is severely limited mainly by the repolarized M1-like macrophages belatedly returning to the M2-like phenotype (i.e.

Acne vulgaris caused by antibiotic-resistant () infection is difficult to treat conventionally. Phages have been suggested as a potential solution, but research on the mechanism of phage treatment is inadequate. This research investigates the underlying molecular mechanisms of phage φPaP11-13 attenuating -induced inflammation in rat models.

High altitude could influence the level of exposure to neonicotinoids, but relevant data remain limited for people living in Tibet. We investigated 476 Tibetan pregnant women from Lhasa of Tibet, China in 2021 and measured eight neonicotinoids and four metabolites in urine. Food consumption was investigated by a food frequency questionnaire.

Article Synopsis
  • Current sorbents for removing Cr (VI) from electroplating wastewater face challenges in separation, regeneration, and disposal of adsorbed chromium species.
  • The newly developed CuS/TiO sorbent demonstrated superior removal performance, effectively extracting Cr (VI) at a rate of 9.36 mg/g and a capacity of 68.8 mg/g at a pH of 4.0.
  • CuS/TiO not only helps recover chromium but also minimizes secondary pollution by converting released copper into a stable precipitate, and can be regenerated for multiple uses, potentially turning recovered chromium into a valuable industrial resource.

Herein, the effect of the diameter of polyamide 11 nanofibers (PA11 NFs) on their internal structures as well as thermal and mechanical properties is investigated. Aligned PA11 NFs with diameters ranging from 109 to 462 nm are prepared by the single-component solvent electrospinning of different PA11/1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) solutions (4-8 wt%) and subsequently characterized. Owing to the similar hydrogen bond formation within the NFs during electrospinning, all prepared NFs have δ'-phase crystals with similar crystallinities and crystallite sizes.

The detection of non-protein nitrogen adulterants is a major challenge in dairy testing. As a marker molecule of animal hydrolyzed protein, the presence of non-edible L-hydroxyproline (L-Hyp) molecules can be used to identify low-quality milk containing components of animal hydrolyzed protein. However, it is still difficult to detect L-Hyp directly in milk.

Tibetan people are one Chinese ethnic minority living in Qinghai-Tibet Plateau with an average altitude of more than 4500 m. High altitude could cause a different antibiotic exposure, but relevant information is limited in Tibetan people. We investigated 476 Tibetan pregnant women in Lhasa, Tibet in 2021 and measured 30 antibiotics from five categories in urine, including 13 veterinary antibiotics (VAs), five human antibiotics (HAs), and 12 human/veterinary antibiotics (H/VAs).
