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 through a myelosuppressive effect. High clinical suspicion and early use of antimicrobials play a major role in decreasing any associated morbidity and mortality. This has led to a widespread use of antimicrobials in cancer patients. Antimicrobial use, however, does not come without its perils. Dysbiosis caused by antimicrobial use affects responses to chemotherapeutic agents and is prognostic in the development and severity of certain cancer treatment-related complications such as graft-versus-host disease and Clostridioides difficile infections. Studies have also demonstrated that an intact gut microbiota is essential in the anticancer immune response. Antimicrobial use can therefore modulate responses and outcomes with immunotherapy targeting immune checkpoints. In this review, we highlight the perils associated with antimicrobial use during cancer therapy and the importance of a more judicious approach. We discuss the nature of the pathologic changes in the gut microbiota resulting from antimicrobial use. We explore the effect these changes have on responses and outcomes to different cancer treatment modalities including chemotherapy and immunotherapy, as well as potential adverse clinical consequences in the setting of stem cell transplant.

People with eating disorders (EDs) have elevated rates of suicide attempts. A need exists to identify factors that help predict which people with EDs might be at greater risk for suicidal behavior. Adverse childhood experiences (ACEs) are associated with both EDs and with suicide attempts. Thus, the current study examined whether having histories of ACEs and EDs augments lifetime risk for suicide attempts.

This study included 36,146 adult participants in the National Epidemiologic Survey on Alcohol and Related Conditions-III who completed structured diagnostic interviews and answered questions regarding ACEs and suicide attempts. Weighted means, frequencies, and cross-tabulations were computed for prevalence of ACEs and suicide attempts by ED diagnosis. check details Multiple logistic regression was used to compare risk of lifetime suicide attempts by ED diagnosis and ACE history.

Prevalence of ACEs among people with EDs was 54.1-67.8%. ACE history and ED diagnosis were associated with elevated odds of experiencing a lifetime suicide attempt (AORs = 4.
