Therefore, the aim of this study was to determine whether chemical signals are involved in the mating process of M. spectabilis. In the first trial, the insect's behavior was evaluated in cages with male: female ratios of 4:1 and 1:4. As soon as copulation began, the behavior of males or females around the copulating couple was recorded. In subsequent trials, the olfactory responses of males and females of M. spectabilis were evaluated in a Y-shaped olfactometer for volatiles released by males, females and mating pairs. At a male: female ratio of 4:1, there were significantly more touches by the other males of the copulating couple. The number of individuals attached to the copulating couple and the copulation time did not differ significantly in relation to the male: female ratio used. The attractiveness of males to copulating pairs was also observed in the olfactometry test, in which males were significantly attracted only to copulating pairs and to the extract of copulating pairs. The females showed no olfactory attraction to any of the odor sources offered.

In the medical sector, nanosilver has been recombined with medicinal plant extracts that contain antimicrobial and antioxidant properties. Nanosilver has also been used in photodynamic Inactivation or other terms photoantimicrobial as a photosensitizer agent. Photoinactivation is a light-based therapy technique to kill pathogenic microbial or fungal cells. This research investigates the ability of biosynthesized nanosilver using Moringa leaf extract (AgNPs-MO) to inhibit Candida albicans biofilm growth. The aspects observed were optical characteristics, photoantimicrobial activity and changes in biofilm cell morphology through the results of Scanning Electron Microscope (SEM) observations. The research results showed that the optics characteristics of nanosilver-moringa oleifera experienced a shift in the absorption wavelength compared to individual investigations of each nanoparticle and Moringa leaf extract. Single nanoparticles did not show significant wave peaks, Moringa leaf extract with λmax1=425 nm and λmax2=635 nm, while the AgNPs-MO spectrum produced λmax=440 nm. Photoantimicrobial activity for cell viability tests, the treatment with the maximum inhibitory effect was the AgNPs-MO combination LED group, 75% (red LED) and 80% (blue LED), respectively. Another indicator of photoantimicrobial activity is the malondialdehyde level produced in each Candida albicans cell due to lipid oxidation. The maximum malondialdehyde level was 1.7 nmol/mL. SEM observations show severe morphological damage was visual for the AgNPs-MO combination LED treatment group. This research is new in developing and utilizing therapeutic approaches that can potentially treat infectious diseases and overcome their severity in the future.

Predictive biomarkers such as HER2/neu expression, estrogen receptor (ER)/progesterone receptor (PR) status, and genomic signatures play a crucial role in treatment decisions, particularly for hormone receptor-positive and HER2-positive tumors. Immunologic markers, including PD-L1 expression, microsatellite instability (MSI), tumor mutational burden (TMB), and tumor-infiltrating lymphocytes (TILs), are essential for predicting responses to immunotherapy, especially in aggressive subtypes like triple-negative breast cancer (TNBC). However, challenges such as tumor heterogeneity, therapy resistance, and standardization of biomarker testing remain significant barriers.
