UNLABELLED Fe-S clusters are cofactors conserved through all domains of life. Once assembled by dedicated ISC and/or SUF scaffolds, Fe-S clusters are conveyed to their apo-targets via A-type carrier proteins (ATCs). Escherichia coli possesses four such ATCs. ErpA is the only ATC essential under aerobiosis. Recent studies reported a possible regulation of the erpA mRNA by the small RNA (sRNA) Ry...

Campylobacter jejuni is the leading cause of bacterial enteritis in Europe. Human campylobacteriosis cases are frequently associated to the consumption of contaminated poultry meat. To survive under environmental conditions encountered along the food chain, i.e., from poultry digestive tract its natural reservoir to the consumer's plate, this pathogen has developed adaptation mechanisms. Among ...

Avena Coleoptile, Elongation Growth, Anoxia, Auxin, NAD(P)H, Proton Pump Avena sativa coleoptile segments show an anomalous increase in elongation growth following a short period of oxygen deprivation (tested between 0 and 60 min) lasting 20-30 min (^«aerobiosis-^erobiosis transition effect = ANA effect). The increase in growth rate is 600% and is commensurate with that observable following an ...

s / Journal of Equine Veterinary Science 34 (2014) 76 76 x106sperm/mL. Sperm recovery rate after centrifugation was lower in low concentration samples (p<0.001). Mean lactate concentration at T0 was the same in all three groups and directly correlated with raw semen volume (r1⁄40.5032; p1⁄40.0103). Lactate concentrations at T0 and T24 were not correlated. Compared to T0, lactate concentration w...

The most obvious periodicities of biological systems are the "clock phenomena."1 An example of periodic fluctuations at the biochemical level is provided by the luminescence of Gonyaulax.2 In this case, at least the intracellular localization of the biological system involved is known,1 but the nature of the oscillator driving such clocks is unknown at either the physiological or the biochemica...

Sterile press juice as a suitable experimental medium. Appl. Microbiol. 11:458-462. 1963.-A sterile raw fish muscle press juice, diluted 1:4 with saline, has been prepared. This dilution greatly facilitated Seitz filtration and affected the spoilage ...

The use of autogenous bone grafts is considered to be the best choice for reconstructive surgery. In the periodontal literature, the utilization of osseous coagulum was suggested by the end of the sixties. The purpose of this study is to consider the use of bone collectors (bone traps) as an alternative method for obtaining material to fill small bone imperfections, such as fenestrations and de...

Cholera is an acute diarrheal disease caused by the presence of Vibrio cholerae O1 in the small intestine after ingestion the food or water contaminated with Vibrio cholerae O1. In particular, attenuated vaccines seem to be one of the most promising variants and for their approval, is necessary clinical evaluation. The Cuban Regulatory Agency, Center for State Control of Drugs, Medical Equipmen...
