Summary: This study evaluated the effects of silver nitrate (AgNO3) and nano-silver (Ag-NPs) on the physiological and biochemical characteristics, and quality of grape bunches during cold storage. The results showed that both AgNO3 and Ag-NPs improved the longevity and quality of the fruits. Immersion in Ag-NPs was found to be the best application for maintaining overall storage quality for both grape varieties.

Summary: This study characterizes the efficacies of five bactericidal chemicals against the causal agent of bacterial wilt in dry bean, Curtobacterium flaccumfaciens pv. flaccumfaciens (CFF). The study found that streptomycin and oxysilver bisulfate were the most effective in controlling seed-borne bacterial wilt of bean. It also discovered that CFF forms biofilms, which are more challenging to eradicate than their planktonic counterparts. Antibiofilm bactericides like streptomycin and oxysilver bisulfate are therefore the best suited for disease management.

Summary: In this study, organomodified montmorillonite and halloysite nanoclays were used to enhance intercalation characteristics, and Ag+ ions were doped to enhance antimicrobial properties. Various analyses showed that the interlayer space of the nanoclays increased and Ag+ ions successfully doped into the nanoclay structure. Additionally, MMT-type nanoclay samples released more Ag+ ions compared to halloysite-type nanoclay samples. The results demonstrated that intercalated and Ag+-doped nanoclays effectively inhibited bacterial growth.

Summary: Silver nanoparticles (AgNPs) are commonly used in consumer products for their antimicrobial properties and can enter aquatic ecosystems through wastewater. This study investigated the toxicity of AgNPs and AgNO3 on Lemna minor at different initial frond densities. Results showed that plants at higher initial frond densities were more sensitive to silver, with lower growth rates observed in both silver treatments. Competition and crowding at high frond densities resulted in reduced growth in the presence of silver.

Summary: This study aimed to analyze the effects of 10 nm gold nanoparticles (GNPs) on DNA double strand break (DSB) induction and repair in tumor cells exposed to different levels of radiation. The results showed that low concentrations of GNPs enhanced the G2/M cell cycle arrest and increased the proportion of radiosensitive G2 cells, but did not increase the extent of DNA damage. GNPs also accelerated DSB repair kinetics and slightly increased the presence of unrepaired gamma H2AX/53BP1 foci at 24 hours post-irradiation. The effects of GNPs on cell survival were only significant at the highest radiation dose tested.

Summary: This paper discusses the spectroscopic properties of trithiocyanuric acid (ttcH(3)) in its natural, anionic and deutered forms using FT-IR and Raman spectroscopy. A trinuclear nickel(II) complex with anionic, hexadentate ligand (ttc(3-)) is synthesized and its band assignments are performed based on computational results and comparison to a previously discussed ttc(3-) anion. Neutralizing ttcH(3) acid to obtain the ttc(3-) anion results in shifts in vibrational spectra, particularly in the characteristic symmetric nu(Ni-S) stretching vibrations band. The experimental data are supported by DFT calculations and PED analysis, which highlights the importance of interpreting the spectra based on the obtained complex rather than literature data.

Summary: The combination of in ovo and ex ovo chorioallantoic membrane (CAM) assay has been used to study the anticancer activity of platinum nanoparticles (PtNPs) and the fluctuations of amino acids in the liver and brain. PtNPs showed higher efficiency in inhibiting tumor growth and metastasis compared to cisplatin (CDDP). PtNPs had a depleting effect on amino acid content, while CDDP treatment had more side effects on amino acid metabolism. Different sets of enzymes in the tricarboxylic acid (TCA) cycle were targeted by PtNPs and CDDP, indicating different mechanisms of action. CAM assay demonstrated the capability of PtNPs to repress angiogenesis, decrease amino acid content, and disrupt the TCA cycle.
