The gut microbiota plays a crucial role in modulating anticancer immunity, significantly impacting the effectiveness of various cancer therapies, including immunotherapy, chemotherapy, and radiotherapy. Its impact on the development of cancer is complex; certain bacteria, like and , can stimulate the growth of tumors by causing immunological evasion and inflammation, while advantageous strains, like , have the ability to suppress tumors by modifying immune responses. Cytokine activity and immune system regulation are intimately related.

Although significant progress has been made, obstacles still exist since cancers are skilled at avoiding immune monitoring. The gut microbiota is being looked at more and more in modern research as a critical component in improving the results of immunotherapy.

Elevated levels of Cleaved-Poly (ADP-ribose) polymerase-1 (PARP1) and microRNA-155 (MiR-155) are related to poor prognosis of disease. Berberine as a natural isoquinoline alkaloid, has shown an anti-tumor potential in tumor cells.

Iran as one of the most affected countries needs unprecedented effort for monitoring and evaluation of COVID-19.
Objective: To determine the seroprevalance of COVID-19 in Semnan province North-East of Iran.
The rapid spread of coronavirus disease 2019 (COVID-19), a disease caused by severe acute respiratory syndrome coronavirus 2, poses a huge demand for immediate diagnosis. Real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) of nasopharyngeal (NP) and oropharyngeal (OP) swabs have been used to confirm the clinical diagnosis. To avoid the risk of viral-exposure of laboratory workers, thermal inactivation is currently recommended but has unknown effects on the accuracy of the rRT-PCR results.

The results demonstrated that the number of antibodies conjugated per liposome in the optimized post-insertion technique was almost two times more than those in the routine post-insertion method. However, the drug release and leakage pattern was almost similar between the two methods.

However, the action mechanism of berberine in CLL cells is unknown. The previous study has shown that berberine leads to reduced viability and elevated levels of apoptosis in PBMCs of CLL patients.

IR, UV-Vis, AFM, SEM, Melting point, X-ray diffraction (XRD), elemental analysis, and H NMR techniques were employed to characterize the chemical structures and properties of these compounds. XRD, UV-Vis, and H NMR techniques confirmed the formation of Schiff base and its functionalized-chitosan to metals.

Intestinal gut microflora is important to maintain and contributes to several intestinal functions, including the development of the mucosal immune system, absorption of complex macromolecules, synthesis of amino acids/vitamins and the protection against pathogenic microorganisms. It is well known that the gut microbiota changes or dysbiosis may have an essential impact in the initiation and promotion of chronic inflammatory pathways and also have a profound different genetic and epigenetic alterations leading to dysplasia, clonal expansion, and malignant transformation.
