The main issues with current and traditional cancer therapy delivery systems include a lack of selectivity towards tumors, causing harm to healthy cells, low efficiency in loading drugs, and the inability to visually track the drug's localization after administration. These limitations negatively impact the effectiveness of therapy and result in increased treatment costs. Furthermore, conventional cancer therapies typically target tumor cells through a single mechanism, which eventually leads to the emergence of drug resistance.

Due to the prevalence of drug-resistant bacteria and the ongoing shortage of novel antibiotics as well as the challenge of treating breast cancer, the therapeutic and clinical sectors are consistently seeking effective nanomedicines. The incorporation of metal oxide nanoparticles with biological macromolecules and an organic compound emerges as a promising strategy to enhance breast cancer treatment and antibacterial activity against drug-resistant bacteria in various biomedical applications. This study aims to synthesize a unique nanocomposite consisting of CeO embedded with folic acid and carboxymethyl cellulose (CFC NC) via a green precipitation method using Moringa oleifera.

Article Synopsis
  • Nitrogen deficiency in low organic matter soils negatively impacts crop yield and plant health, particularly for tomato plants.
  • A study investigated the effects of indole acetic acid (IAA), trehalose (TA), and nanoparticles-coated urea (NPCU) on nitrogen-deficient tomatoes, finding that a combination of 2mM IAA and 0.1% TA with NPCU significantly enhanced several growth metrics.
  • The findings suggest that this combination can be an effective strategy for improving growth and yield in nitrogen-poor soils and should be tested further across different crops and climates.

  • Arsenic (As) is a harmful environmental pollutant that negatively affects plants by disrupting their growth, nutrient absorption, and overall health, leading to stunted growth and low yields.
  • The study explores using a combination of rhizobacteria (specifically Bacillus faecalis) and composted biochar (ECB) to enhance maize growth under varying levels of arsenic contamination.
  • Results indicate that the treatment combining 0.5% composted biochar with B. faecalis significantly improved various growth metrics of maize, including plant height and nutrient concentration, suggesting it could be an effective strategy for alleviating arsenic stress in agricultural settings.

  • DNA binding proteins known as Dof transcription factors are crucial for seed development and plant resilience to various stresses, but their genomic analysis in pitaya (Selenicereus undatus) was previously uncharted.
  • The study identified 26 Dof genes, categorized them into seven subfamilies based on their genetic characteristics, and discovered that gene duplications were influenced by natural selection.
  • Additionally, researchers found that certain Dof genes showed significant expression during different flower development stages and highlighted three candidate genes that may help pitaya plants cope with abiotic stresses, laying groundwork for future genetic improvement efforts.

Drought stress poses a significant challenge to maize production, leading to substantial harm to crop growth and yield due to the induction of oxidative stress. Deashed biochar (DAB) in combination with carboxymethyl cellulose (CMC) presents an effective approach for addressing this problem. DAB improves soil structure by increasing porosity and water retention and enhancing plant nutrient utilization efficiency.

Kam Sweet Rice is a high-quality local variety of Guizhou province in China, but most varieties have awns on lemma. In this study, we aimed to obtain awnless varieties of Kam Sweet Rice by blocking the awn development-related gene OsGAD1 using CRISPR/Cas9 technology. We determined that natural variations of the OsGAD1 triggered different lengths of awns of Kam Sweet Rice.

The deleterious impact of osmotic stress, induced by water deficit in arid and semi-arid regions, poses a formidable challenge to cotton production. To protect cotton farming in dry areas, it's crucial to create strong plans to increase soil water and reduce stress on plants. The carboxymethyl cellulose (CMC), gibberellic acid (GA) and biochar (BC) are individually found effective in mitigating osmotic stress.

Maize cultivated for dry grain covers approximately 197 million hectares globally, securing its position as the second most widely grown crop worldwide after wheat. Although spermidine and biochar individually showed positive impacts on maize production in existing literature, their combined effects on maize growth, physiology, nutrient uptake remain unclear and require further in-depth investigation. That's why a pot experiment was conducted on maize with spermidine and potassium enriched biochar (KBC) as treatments in Multan, Pakistan, during the year 2022.
