Obesity, characterized by excessive accumulation of body fat, is associated with reduced vitamin D levels. Several polymorphisms of the vitamin D receptor exist, such as TaqI (rs731236), although their association with obesity remains inconsistent. The aim of this study was to evaluate the effect of TaqI polymorphism on biomarkers in individuals with obesity. The study has been approved by the Research Ethics Committee of the...
Phoresy, a common dispersal strategy among arthropods, involves complex relationships between hosts and symbionts that influence ecological dynamics. Investigating the structure of phoretic mite communities and their population fluctuations is particularly relevant for widely distributed agricultural pests, such as the coconut palm weevil, Rhynchophorus palmarum . This study investigated the community of phoretic mites associa...
Predictive validation of the repeated low-dose reserpine rodent model of parkinsonismNARA Subscribed
L-DOPA (LD) is the gold-standard treatment of motor symptoms in Parkinson’s disease (PD), conventionally used to prove the predictive value of PD animal models. This study aimed to investigate the predictive validity of an adaptation of the conventional reserpine model of PD: the repeated low-dose reserpine administration in rodents, which promotes progressive motor impairment in catalepsy, vacuous chewing behavior tests, and...
Influence of food resources and prey egg age on the predatory efficiency of phytoseiid mites associated with cashewNARA Subscribed
Under field conditions, predator–prey interactions can be modulated by the diverse availability and suitability of food resources, which diet type may alter biological and behavioral parameters of predators. Amblyseius largoensis and Euseius concordis are phytoseiid predatory mites identified as potential biological control agents for the giant whitefly, Aleurodicus cocois , a major pest of cashew trees. In the present study,...
Mating behavior and preliminary evidence of putative odor-mediated interactions in Raoiella indica (Acari: Tenuipalpidae)NARA Subscribed
Odour and contact chemical traces play central roles in the sexual communication of mites, mediating partner encounter and recognition of the female reproductive status. We investigated the mating behavior of Raoiella indica Hirst and the role of female-associated chemical cues in male attraction. Behavioral observations were conducted under controlled laboratory conditions, and three complementary bioassays were performed: (i...
