We review recent evidence that suggests that hormonal contraceptives may influence the dynamics of sexual relationships and the human pair-bond. Hormonal contraception likely has positive effects on cementing the pair-bond by decoupling sex from conception.

With the purpose of providing better guidelines on contraception methods for women with risk factors for cardiovascular disease, we have reviewed the literature on the subject. This review describes the latest dat...

Sheath blight disease is caused by a necrotrophic fungal pathogen Rhizoctonia solani and it continues to be a challenge for sustainable rice cultivation. In this study, we adopted a multi-pronged approach to understand the intricacies of rice undergoing susceptible interactions with R. solani. Extensive anatomical alteration, chloroplast localized ROS, deformed chloroplast ultrastructure along ...
