In the 6-6 bonding configuration, no excitation energy transfer was observed. In contrast, in the 5-6 bonding configuration, several LE and charge-transfer (CT) excitons were shown to participate in the energy-transfer process. Further analysis reveals that the photoinduced energy transfer is mediated by a CT exciton, such that electron- and hole-transfer processes take place in a concerted but asynchronous manner in the excitation energy transfer. It is also found that high-level electronic structure methods including exciton effects are indispensable to accurately describe photoinduced energy- and electron-transfer processes. Furthermore, this work opens up new avenues for regulating the excited-state properties of molecular donor-acceptor dyads by means of chemical bonding.Different gradient concentrations of vitamin B12 (0, 10, 100, 1,000 ng L-1 ) were used in the symbiosis system (Chlorella vulgaris-Ganoderma lucidum or Chlorella vulgaris-Pleurotus ostreatus) to assess their effect on simultaneous purification of biogas and removal of nutrients in biogas slurry using co-culture of microalgae and fungi. When B12 was added to the symbiosis system, biomass growth, intracellular carbonic anhydrase activity (CA), chlorophyll a content (CHL-a), photosynthetic characteristics of the two cultivation system, and removal efficiency of nutrients in biogas slurry and CO2 in biogas were significantly higher than those in the control group. The optimal concentration of B12 was determined to be 100 ng L-1 considering the removal efficiency of nutrients and CO2 . Maximum mean chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP), and CO2 removal efficiencies were 75.98 ± 6.26%, 78.46 ± 6.21%, 80.21 ± 6.83% and 61.08 ± 5.21% in Chlorella vulgaris-Ganoderma lucidum, respectively. This study showed the potential of microalgae and fungi symbiosis system with B12 addition for nutrient removal and biogas upgrading. PRACTITIONER POINTS Vitamin B12 had positive effects on algal-fungal pellets growth. The optimal vitamin B12 concentration was 100 ng L-1 . The highest CO2 remove rate was 61.08% by G. lucidum/C. vulgaris pellets. Vitamin B12 significantly improved photosynthetic performance of pellets. The aim was to compare the quality of sexual life before pregnancy and after delivery and to find out whether and how selected factors affect women's sexuality during this period. The study group consisted of 433 women who completed the survey containing basic demographic questions and two Female Sexual Function Index (FSFI) questionnaires a retrospective one, regarding time before pregnancy and the current period. The inclusion criteria time between 10 weeks and 1 year after delivery, vaginal intercourses before pregnancy and the resumption of vaginal intercourses after delivery. We observed the negative impact of labor on the total FSFI score, regardless of the time that had passed since birth and the delivery mode. The decrease by at least 10% of the initial FSFI score was noticed in 44.3% of the participants. FSD (Female Sexual Dysfunction) occurred statistically more commonly after delivery than before pregnancy (45.3% vs 17.1%; P < 0.001). The following factors had an impact on the risk of post-partum FSD pre-pregnancy FSD (adjusted odds ratio [aOR] = 4.17 [95% confidence interval [CI] 2.38-7.31]) and nulliparity (aOR = 1.67 [95% CI 1.09-2.53]). Childbirth has an undeniable impact on women's sexuality. The prevention and treatment of sexual dysfunctions is very important, especially in this crucial period of life.

Chemoradiation places the patient at a higher risk of infection thro
