Background
Bisphenol A (BPA), an endocrine-disrupting chemical (EDC), is ubiquitous in our environment and poses a significant threat to male fertility. Date seeds (DSs) are used in folk medicine due to their antioxidant activity.
Aim
The purpose of this study was to assess the beneficial effects of DSs, whether in powder or nanoparticle form, against BPA-induced testicular oxidative challenges and apoptosis, aided by inspection of specific genes linked to fertility, oxidative stress and intrinsic mitochondrial pathway of apoptosis.
Methods
Thirty-five adult male albino rats were equally divided into 5 groups including control, BPA, BPA + date seeds powder “DSP”, BPA + date seed nanoparticle 1/10 (DSNP 1/10) and BPA + DSNP 1/20 groups.
Results
TEM showed that the ball-mill method was effective to form DSNP with an average size of 20 nm. BPA significantly impaired sperm motility, morphology, viability and concentration. It also reduced serum testosterone levels and evoked marked oxidative stress in the testes. Additionally, serum levels of triiodothyronine and thyroxine were extremely reduced. Moreover, testicular mRNA relative expression levels of CYP11A1 and Nrf-2 were markedly downregulated. Testicular apoptosis was also promoted whereas Bax/Bcl-2 ratio was profoundly elevated. Histological pictures of the testes, epididymis, seminal vesicles and prostate confirmed the unfavorable effects of BPA. Surprisingly, we first demonstrated that DSs, specifically the nanoparticle form, strongly alleviated all of BPA’s negative effects, with DSNP 1/20 achieving the best results.
Conclusion
Therefore, DSNP in both doses could be regarded as an ideal candidate for abating the male reproductive challenges caused by BPA.
Rheumatoid arthritis (RA) is an autoimmune lifelong disease. Systemic manifestations represent a significant aspect of the disease burden. This study aimed to assess sleep quality and psychosocial aspects among RA patients and the impact of disease duration and activity.
The mean age for included RA patients was 50.00 ± 9.37 years. The median disease duration was 9.50 (Interquartile range (IQR)=5–15) years and 90% of patients were females. Disease activity score 28 was 4.65 ± 1.66. Anxiety and depression were significantly higher among RA participants. Regarding sleep quality assessment, RA group had significantly higher levels of insomnia than the control group (Insomnia Severity Index median (IQR) was 4.5 (0–15) versus 1 (0–3); p value = 0.013) and daytime sleepiness (Epworth Sleepiness Scale median (IQR) was 4 (1–11.25) versus 1 (0–3); p value = 0.002). RA patients showed significantly higher values of Pittsburgh Sleep Quality Index components as well as the global score indicating poor sleep quality. The 36-item short-form health survey domains, representing physical and mental health, were significantly lower among RA cases versus control subjects. Higher disease activity was positively correlated with anxiety, depression, insomnia, sleep quality, sleep efficiency, and daytime dysfunction, while negatively correlated with all domains of the 36-item short-form health survey.
RA patients have increased anxiety and depression levels in addition to poor sleep quality. High disease activity is linked to increased anxiety and depression levels, impaired quality of life, and poor sleep quality.
