Sugarcane juice has a pleasant flavor, is easy to process, and is well-accepted by the general population. However, microbiological quality is not always assured, which can result in risks for consumption. The objective of this study was to evaluate the microbiological quality of sugarcane juice obtained from commercial establishments in the city of Goiânia. Sugarcane juice samples were collected from 21 locations between February and July 2018. The analysis was performed using the multiple tube technique, and quantification by the most probable number (MPN) of microorganisms present in each sample. The microbiological analysis investigated total and thermotolerant coliforms, in addition to Salmonella, as recommended by current legislation. Total coliforms were found in 100% of the samples, with a count >1600 MPN/mL in 57.1%. For thermotolerant coliforms, 100% of the samples were positive, with 33.3% being above the legal limit and 19.1% being positive for Escherichia coli. Among the 21 samples evaluated, one was positive for Salmonella ser. Typhimurium. The quantity and quality of microorganisms isolated in the sugarcane juice samples sold in the city of Goiânia indicate the need to improve the hygienic and sanitary quality of the establishments. There is an urgent need to establish training courses for traders in this sector to provide guidance on the correct way to process, store, and transport food and raw materials, which will guarantee the quality of the food and protect the health of the consumers.

Background Context Damage to the spinal cord can result in irreversible impairment or complete loss of motor, sensory, and autonomic functions. Riluzole and dantrolene have been shown to provide neuroprotection by reducing neuronal apoptosis after brain and spinal cord injury (SCI) in several animal models of neurologic disorders. As these drugs protect the injured spinal cord through different mechanisms, we investigated the cumulative effects of riluzole and dantrolene. Purpose This study aimed to investigate the neuroprotective efficacy of the combined administration of riluzole and dantrolene in experimental thoracic SCI. Study Design Twenty-nine Wistar rats were laminectomized at T12 and divided in five groups. Rats in GI (n=6) underwent laminectomy alone and were treated with placebo. Rats in GII (n=6) underwent laminectomy followed by SCI and were treated with placebo. Rats in GIII (n=5) underwent laminectomy followed by SCI and were treated with riluzole and placebo 15 minutes and 1 hour after laminectomy, respectively. Rats in GIV (n=6) underwent laminectomy followed by SCI and were treated with placebo and dantrolene 15 minutes and 1 hour after laminectomy, respectively. Rats in GV (n=6) underwent laminectomy followed by SCI and were treated with riluzole and dantrolene 15 minutes and 1 hour after laminectomy, respectively. A compressive trauma was performed to induce SCI. Methods Behavioral testing of hind limb function was performed using the Basso Beattie Bresnahan locomotor rating scale, which revealed significant recovery in the group treated with the association of riluzole and dantrolene compared with other groups. After euthanasia, the spinal cord was evaluated using light microscopy and immunochemistry with anti-NeuN and transferase dUTP nick-end-labeling (TUNEL) staining. Results Animals treated with the association of riluzole and dantrolene showed a larger number of NeuN-positive neurons adjacent to the epicenter of injury (p≤.05). Furthermore, the TUNEL staining was similar between animals treated with riluzole and dantrolene and those that did not receive spinal cord trauma (p>.05). Conclusions These results showed that riluzole and dantrolene have a synergistic effect in neuroprotection after traumatic SCI by decreasing apoptotic cell death.
