In vitro models are common tools in nephrology research. However, their validity has rarely been scrutinized. ⋯ The findings of this study suggest that in vitro findings should be interpreted cautiously and if possible are substituted or supported by animal models that are more consistent and reliable. Furthermore, we underscore the importance of time-course evaluation of both case and control groups in gene expression studies to avoid misconceptions caused by gene expression noise or intrinsic rhythms.

Rheumatoid arthritis (RA) is the most prevalent autoimmune disease, in which CCL2 and CCL5 are critically involved. The objective was to evaluate the therapeutic effects of bone marrow-derived mesenchymal stem cells (MSCs) on the foregoing chemokines in RA patients. ⋯ The most significant inhibitory effects of MSC therapy on the gene expression and plasma level of CCL5 were observed at the end of 1 month. The differences between the gene expression and protein levels during the treatment might be related to microRNA effects or the insufficient number of MSC injection.

Previous studies have shown that morphine negatively effects male fertility while Phoenix dactylifera (dates) could cure male infertility by the exhibition of antagonist effects. This study was conducted to assess the possible ameliorating effects of dates on the histological features of morphine-induced male rat reproductive organs. ⋯ P. dactylifera extract has a protective effect against the adverse effects of morphine on the male rat reproductive organs.

Prolactinoma is a rare tumor of childhood. Clinical presentations of prolactinoma include amenorrhea, delayed puberty, and galactorrhea. For the first time, in this case, elevated prolactin levels were associated with unexpected premature pubarche. ⋯ Prolactin level and tumor size markedly reduced. At the 9-month follow-up visit, a normal MRI was reported. This case highlights that even when facing premature pubarche, careful examination is mandatory, and if no obvious etiology is found for premature pubarche, clinicians should consider prolactinoma.

Metabolic syndrome (MetS) is a cluster of conditions increasing the risk of serious diseases. This study aimed to define the predictors of MetS incident in a community-based cohort in Southern Iran, during a mean follow-up period of 5.1 years. ⋯ This study showed the high-incidence rates of MetS in males and females residing in Southern Iran. Therefore, the prevention through community-based lifestyle modification should be implemented to reduce the burden of MetS and its complications.
