The mucin -glycan sialyl Tn antigen (sTn, Neu5Acα2-6GalNAcα1--Ser/Thr) is an antigen associated with different types of cancers, often linked with a higher risk of metastasis and poor prognosis. Despite efforts to develop anti-sTn antibodies with high specificity for diagnostics and immunotherapy, challenges in eliciting high-affinity antibodies for glycan structures have limited their effectiveness, leading to low titers and short protection durations. Experimental structural insights into anti-sTn antibody specificity are lacking, hindering their optimization for cancer cell recognition.

Marine invertebrates such as sponges, cnidarians, bryozoans, and tunicates are considered to be prolific sources of novel biologically active natural products. Specimens from these organisms are composed of soft tissues with a high water and inorganic salt content compared to those from terrestrial counterparts. In addition, some of the secondary metabolites from these organisms tend to be more polar than those of terrestrial.

Soil contamination with toxic heavy metals [such as cadmium (Cd)] is becoming a serious global problem due to the rapid development of the social economy. Organic chelating agents such as succinic acid (SA) and oxalic acid (OA) are more efficient, environmentally friendly, and biodegradable compared to inorganic chelating agents and they enhance the solubility, absorption, and stability of metals. To investigate this, we conducted a pot experiment to assess the impact of SA (0.

The emergence of COVID-19 has underscored an urgent demand to develop an innovative, rapid, and reliable diagnostic tool for early detection of the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). Biosensors present a viable alternative, offering reliability, precision, and cost efficiency that address the limitations of current molecular and serological detection methods, thus facilitating timely identification of COVID-19. In this study, a novel nano-genosenor platform fabricated using advanced nanomaterials based on Ce-metal organic framework (Ce-MOF), dendritic palladium nano-structure (Den-PdNS), and sulfur-doped reduced graphene oxide (S-rGO) for detection of RNA-dependent RNA polymerase (RdRp) SARS-CoV-2 gene targets.

Proteins are indispensable for maintaining a healthy diet and performing crucial functions in a multitude of physiological processes. The growth of the global population and the emergence of environmental concerns have significantly increased the demand for protein-rich foods such as meat and dairy products, exerting considerable pressure on global food supplies. Single-cell proteins (SCP) have emerged as a promising alternative source, characterized by their high protein content and essential amino acids, lipids, carbohydrates, nucleic acids, inorganic salts, vitamins, and trace elements.
