Abstract
In brief Mitochondrial uncoupling proteins (UCPs) regulate mitochondrial activity and reactive oxygen species production through the transport of protons and metabolites. This study identified the expression of UCPs in human Sertoli cells, which proved to be modulators of their mitochondrial activity. Abstract Mitochondrial uncoupling proteins (UCPs) are mitochondrial channels responsible for the transport of protons and small molecular substrates across the inner mitochondrial membrane. Altered UCP expression or function is commonly associated with mitochondrial dysfunction and increased oxidative stress, which are both known causes of male infertility. However, UCP expression and function in the human testis remain to be characterized. This study aimed to assess the UCP homologs (UCP1-6) expression and function in primary cultures of human Sertoli cells (hSCs). We identified the mRNA expression of all UCP homologs (UCP1-6) and protein expression of UCP1, UCP2, and UCP3 in hSCs. UCP inhibition by genipin for 24 h decreased hSCs proliferation without causing cytotoxicity (n = 6). Surprisingly, the prolonged UCP inhibition for 24 h decreased mitochondrial membrane potential, oxygen consumption rate (OCR), and endogenous reactive oxygen species (ROS) production. The metabolism of hSCs was also affected as UCP inhibition shifted their metabolism toward an increased pyruvate consumption. Taken together, these findings demonstrate that UCPs play a role as regulators of the mitochondrial function in hSCs, emphasizing their potential as targets in the study of male (in)fertility.

Abstract
BACKGROUND Chronic cutaneous lesions affect 15% of human patients with diabetes, and the associated risk of limb amputations is 15-46 times greater than that of people with normal glycaemia. It is estimated that half of these limb amputations could be avoided by opportune treatment with somatic stem cells or platelet-rich plasma (PRP). METHODS We evaluated the effects of autologous transplant of mesenchymal stem cells (MSCs) with or without combination with autologous PRP in the re-epithelialization of cutaneous lesions induced in diabetic mice. RESULTS Animals treated with MSCs alone showed a similar level of re-epithelialization of cutaneous lesions to those treated with MSC plus PRP, and no significant difference was found between the two treatments. CONCLUSION Both treatments gave better results than daily cleaning of the cutaneous lesions with saline or covering of the lesions with semipermeable adherent bandage.

Abstract
Damage caused by the ant Azteca barbifex (Forel) was identified in orange trees (Citrus sinensis), in Capitão Poço County, Guamá microregion, Pará State. The damage caused by the scraping of stems and branches lead to reduction in yield with subsequent death of the plant. These characteristics indicate A. barbifex as a potential pest of citrus crops in the eastern region of Amazon.

Abstract
The aim of this study was to determine the levels of Penicillium citreonigrum and citreoviridin present in rice samples from Maranhão State, Brazil, where an outbreak of beriberi was reported and 32 deaths occurred (7% of the notified cases died in 2006). The ability of P. citreonigrum to produce citreoviridin was assessed, and a total of 420 samples of 21 different kinds of rice were collected. Mycobiota isolation and identification, the ability of citreoviridin strains to produce toxin, and the natural occurrence of citreoviridin were established. Rice samples were found to have high fungal counts and showed increasing levels from 2004 to 2007 harvest years. The most frequent genus was Aspergillus followed by Penicillium and Cladosporium. Ten out of eleven strains of P. citreonigrum were able to produce citreoviridin. Three rice samples had levels of citreoviridin ranging from 12 to 96.7 ng g(-1), and two bran samples had levels of 128 and 254 ng g(-1). These samples contaminated with P. citreonigrum and citreoviridin were involved in the beriberi cases from Maranhão State. Monitoring rice for mycotoxins in areas where this substrate is the basic food is crucial to prevent outbreaks like the one reported in this study, to improve management practice, and to diminish exposure risk of humans to these harmful toxins.
