Abstract
INTRODUCTION Spinal cord infarction is a rare disease with a high rate of morbidity. Its diagnosis can be challenging and controversy remains regarding the best treatment. Few case series have been published. METHODS We conducted a retrospective review of cases of spinal cord infarction attended in a tertiary hospital from 1999 to 2020. Aetiology and clinical, imaging, and prognostic features were assessed. RESULTS Forty-one patients (58.5% men, mean [standard deviation] age 61 [17] years) were included in the study. Thirty-one patients (75.6%) presented vascular risk factors. Motor deficits were recorded in 39 (95.1%), pain in 20 (48.8%), sensory deficits in 33 (80.4%), and autonomic dysfunction in 24 (58.5%). MRI was performed in 37 (90.2%) patients. Diffusion-weighted images were available for 12 patients, with 10 showing diffusion restriction. The thoracic region was the most frequently affected (68.2%). Vascular imaging studies were performed in 33 patients (80.4%). The most frequent aetiologies were aortic dissection (6 cases), atherosclerosis demonstrated by vascular imaging (6 cases), fibrocartilaginous embolism (6 cases), surgery (5 cases), and hypotension (4 cases). Aetiology was undetermined in 12 patients (29.3%), although 9 of these presented vascular risk factors. At the end of the follow-up period (median, 24 months; interquartile range, 3-70), 12 patients (29.2%) were able to walk without assistance. Vascular risk factors and paraparesis were significantly associated with poorer prognosis (P<.05). DISCUSSION Spinal cord infarction may present diverse aetiologies, with the cause remaining undetermined in many patients. Long-term functional prognosis is poor, and depends on baseline characteristics and clinical presentation. MRI, and especially diffusion-weighted sequences, is useful for early diagnosis.

Abstract
Biocatalysis for industrial application is based on the use of enzymes to perform complex transformations. However, these systems have some disadvantage related to the costs of the biocatalyst. In this work, an alternative strategy for producing green immobilized biocatalysts based on biofilm was developed.A study of the rheological behavior of the biofilm from Bacillus sp. Mcn4, as well as the determination of its composition, was carried out. The dynamic rheological measurements, viscosity (G") and elasticity (G') module, showed that the biofilm presents appreciable elastic components, which is a recognized property for enzymes immobilization. After the partial purification, the exopolysaccharidewas identified as a levan with a non-Newtonian behavior. Extracellular DNA with fragments between 10,000 and 1000bp was detected also in the biofilm, and amyloid protein in the extracellular matrix using a fluorescence technique was identified. Bacillus sp. Mcn4 biofilms were developed on different surfaces, being the most stable those developed on hydrophilic supports. The biofilm showed lipase activity suggesting the presence of constitutive lipases entrapped into the biofilm. Indeed, two enzymes with lipase activity were identified in native PAGE. These were used as biocatalysts, whose reuse showed a residual lipase activity after more than one cycle of catalysis. The components identified in the biofilm could be the main contributors of the rheological characteristic of this material, giving an exceptional environment to the lipase enzyme. Based on these findings, the current study proposes green and natural biopolymers matrix as support for the enzyme immobilization for industrial applications.

Abstract
Mycotoxicoses are diseases caused by consumption of diets contaminated with mycotoxins, a special class of fungal secondary metabolites. Fumonisin B1 (FB1) and aflatoxin B1 (AFB1), the main toxins synthesized by toxicogenic stocks of Fusarium spp. and Aspergillus spp., respectively, can coexist in grains and in its by-products. We investigated a probable synergism of a fumonisins-containing Fusarium verticillioides culture material and AFB1 in the induction of hepatocyte apoptosis in rats subchronically fed on a mixture of them. Furthermore, the possibility of modifications in the fumonisins-induced Sa/So ratio imbalance in tissues and urine from rats poisoned with this mycotoxin, due to the presence of AFB1 in the diet, was evaluated. The co-exposure to fumonisins and AFB1 produced a higher liver toxicity, with respect to their individual administration, inducing apoptosis and mitotic hepatocytes. There was an inversion of the typical Sa/So ratio in rats fed on the culture material as well as in those subjected to a diet co-contamined with fumonisins and AFB1. Moreover, the later had a synergistic effect in the induction of Sa/So variations in kidneys. Therefore, the mixture of fumonisins and AFB1 induced toxic responses which could not be considered a sum of the effects caused individually by these mycotoxins.

Abstract
The minimum inhibitory concentration (MIC) of Origanum vulgare, Aloysia triphylla, Aloysia polystachya and Mentha piperita essential oils (EOs) against Fusarium verticillioides M 7075 (F. moniliforme, Sheldon) were assessed, using the semisolid agar antifungal susceptibility (SAAS) technique. O. vulgare, A. triphylla, A. polystachya and M. piperita EOs were evaluated at final concentrations of 10, 20, 40, 50, 100, 200, 250, 500, 1000 and 1500 epsilonl per litre (epsilonl/l) of culture medium. A. triphylla and O. vulgare EOs showed the highest inhibitory effects on F. verticillioides mycelial development. This inhibition was observed at 250 and 500 epsilonl/l for EOs coming from Aloysia triphylla and O. vulgare, respectively. Thus, the effects of EOs on FB(1) production were evaluated using corn grain (Zea mays) as substrate. The EOs were inserted on the 5th, 10th, 15th and 20th day of maize postinoculation with a conidia suspension of F. verticillioides. O. vulgare and A. triphylla were applied to give final concentrations of 30 ppm and 45 ppm, respectively. Different effects were observed in the toxicogenicity at the 20th day treatment. The O. vulgare EO decreased the production level of FB(1) (P < 0.01) while A. triphyla EO increased it (P < 0.001) with respect to those obtained in the inoculated maize, not EOs treated. Results obtained in the present work indicate that fumonisin production could be inhibited or stimulated by some constituents of EOs coming from aromatic plants. Further studies should be performed to identify the components of EOs with modulatory activity on the growth and fumonisins production of Fusarium verticillioides.

Abstract
Maize co-contamination with aflatoxin B1 (AFB1) and fumonisin B1 (FB1) is frequently found in several countries. Although the alterations on nutritional and immunologic parameters induced by these mycotoxins, when administered individually, are partially characterised, little is known about the effects induced in animals by a subchronic administration of both toxins mixtures. We have studied the nutritional and immunological alterations induced in rats fed during 90 days with a diet without mycotoxins, containing 40 ppb AFB1, and with a diet containing a mixture of 40 ppb AFB1 and 100 ppm FB1. Animals fed with the mixture of toxins obtained lower body weight than the control ones. The mitogenic response of spleen mononuclear cells (SMC) in vivo was higher in animals fed with AFB1. In in vitro studies, lower proliferations of SMC pre-exposed to AFB1 and to the mixture of toxins were detected. The SMC of animals fed with AFB1 produced lower levels of IL-2, higher of IL-4 and equal levels of IL-10. The SMC of animals fed with both toxins produced higher levels of IL-4, lower of IL-10 and equal levels of IL-2. The SMC preincubated with an AFB1-FB1 mixture produced higher concentrations of IL-4, lower of IL-10 and equal levels of IL-2. The peritoneal macrophages of animals that consumed AFB1 released less H(2)O(2), while animals fed with the mixture of toxins produced higher levels. In in vitro studies, macrophages pre-exposed to the mixture of toxins released less H(2)O(2). These results show different immunobiological effects produced by a mixture of mycotoxins in comparison to the individual action of the same toxins.

Abstract
OBJECTIVES To determine what clinical, analytic and ultrasound parameters, are more effective to predict the result of a second biopsy in patient with high PSA and a first prostate biopsy negative. MATERIAL AND METHODS It was carried out a longitudinal study in a series of 435 cases with negative prostate biopsy. In 59 of these cases it was practiced a second biopsy due to a permanent or sudden high PSA levels with or without a suspicious digital rectal examination. Of the 31 cases with a negative second biopsy, in 4 cases it was carried out a third biopsy. The biopsy was made in all the occasions by transrectal ultrasound guided sextant biopsy. It were also valued the ultrasound characteristic of the prostate, the prostate volume and the proportion of free PSA. RESULTS It was demonstrated statistically significant differences among the patients with a second biopsy negative and positive regarding: the age, proportion of free PSA, abnormal digital rectal examination and presence of hipoechogenic areas in the prostate. The multivariate analysis demonstrated that the only significant parameters were the proportion of free PSA and the existence of an abnormal digital rectal examination. Based on the data of multivariate analysis, we settled down for the patients with normal digital rectal examination a cut-off point of 0.23 of proportion of free PSA as indication for the realization of a second biopsy, and of 0.59 for the patients with abnormal digital rectal examination. This protocol applied to our series would avoid the realization of a second biopsy in 8 patients, and a third biopsy in 1 patient, diagnosing all the cases of prostate cancer. CONCLUSIONS The digital rectal examination associated with the proportion of free PSA constitutes a reliable parameter to indicate the realization of a second prostate biopsy in patient with high PSA and previous negative biopsy.

Abstract
Fumonisin B1 (FB1), the principal secondary metabolite produced by the fungus Fusarium verticillioides (Gibberella fujikuroi mating population A), is a potent toxin that can be found in fungus-contaminated corn and corn-based food products. We have investigated the immunobiological effects of subchronic dietary exposure to FB1 in male Wistar rats. Animals were fed with diets containing 0 (control) or 100 ppm of FB1 for 12 weeks. The total FB1 intake on day 90 was 810 mg/kg of body weight. Food consumption, body weight, and body weight gain on day 90 were reduced in animals exposed to FB1. Histopathologic changes consisted of histiocytic perivascular infiltrate and an increased number of Kupffer cells in the liver, necrosis and apoptosis of tubular epithelial cells in the kidney, and increased mitotic figures and lymphocytic infiltrate in the small intestine. Serum enzyme alkaline phosphatase was significantly elevated in rats fed FB1, while triglyceride levels decreased compared to controls. Treatment with FB1 in vivo or in vitro did not have a significant effect on mitogen-induced proliferation of spleen mononuclear cells. However, increased levels of interleukin-4 (IL-4) and decreased levels of IL-10 were released by these cells in culture compared to controls. FB1 in vivo or in vitro decreased the hydrogen peroxide (H(2)O(2)) released by peritoneal macrophages, while no changes in levels of superoxide anion produced by total peritoneal cells were detected. The results from the present work demonstrate that subchronic FB1 intake could affect the small intestine and alter the interleukin profile and some main functions of macrophages in antitumor activity.

Abstract
OBJECTIVES To determine what tests have a better diagnosis utility in patient with suspected prostate cancer due to PSA equal or greater than 4 ng/ml or abnormal digital rectal examination in order to reduce the number of negative prostate biopsies. MATERIAL AND METHODS We carried out a ultrasound-guided sextant transrectal biopsy in a series of 400 patient with prostate-specific antigen (PSA) levels equal or greater than 4 ng/ml or abnormal digital rectal examination. All patients had also transrectal rectal ultrasonography to value the echographic prostatic characteristics and the prostatic volume, and a free PSA determination. RESULTS The free/total PSA ratio (PSAl) and the PSA density (DPSA) were the most powerful predictors of prostate cancer, both with a 66% sensitivity and a 70% specificity (at a 0.15 cutoff), followed by the total PSA (PSAt), the digital rectal examination and the hypoechogenic prostatic nodules. We constructed a logistic multivariate model with these data. The outcome variable of logistic model was the probability of having prostate cancer. The significant predictive variables of the model were the PSAl, the DPSA, the digital rectal examination and the presence and extension of hypoechogenic prostatic. This model had a 81% sensitivity and 79% specificity at a 0.24 probability cutoff. We considered a 0.1 probability cutoff to reduce the number of false negative. With this strategy the sensitivity was 94% and the specificity 54%. If we had applied this model to the patient of our series then, we would be able to avoid prostate biopsy in 164 cases (the 41% of the patient), leaving only 7 cases without diagnosis of prostate cancer. CONCLUSIONS The most effective combination parameters were the digital rectal examination, PSAl, presence and extension of prostatic hypoechogenic zones and DPSA. This combination allows us to diminish the percentage of negative prostate biopsy in patient with prostate-specific antigen (PSA) levels equal or greater than 4 ng/ml or abnormal digital rectal examination without significantly descending the number of detected prostate cancers.

Abstract
From January to December 1997, stools submitted for routine culture were also screened for E. coli O157:H7 to investigate its incidence in our area. Bloody and non-bloody stools were studied. E. coli O157:H7 was not recovered from any of the samples tested. We believe, therefore, that we are in a low rate of infection area, and accordingly do not recommend routine screening of this pathogen.

Abstract
We report another case of multilocular cyst of the kidney. We underscore the current theory on the neoplastic and not cystic origin of this disease entity. Attention is drawn to the confusion arising from a wide variety of terms (17) used to refer to this disease entity. Its clinical features, diagnosis, and treatment are briefly discussed. We highlight the need to follow currently available diagnostic criteria in diagnosing multilocular cyst of the kidney.

Abstract
Multilocular Renal Cyst is a variety contained within the Spectrum of Renal Embryonic Tumors, presenting much confusion relating to its terminology, histology, clinical aspects, etc. We have carried out a review of this subject through bibliographical compilation of the cases published between 1976-86, and close analysis of the series thus far published. The diagnostic criteria described by Boggs and Kimmeslstiels in 1956, which classify this entity separate from other varieties of R.E.T. and similar ones. This pathological state can be seen in both children and adults, and it is characterized by its unusual appearance, clinical silent in the adults and in the child it appears as an abdominal mass. This pathology lacks specific diagnostic tests as well as the assistance rendered by clinical, radiological or ultrasound studies, it will depend on a correct preoperative diagnosis, an extremely difficult task to achieve, or on a diagnostic approximation geared to avoid in the child population the implementation of coadjuvant measures to surgery that will no doubt give rise to unwanted situations in the long run. The treatment of this pathology is strictly surgical and must be preceded by an extremely conservative approach. Tumorectomy or Partial Nephrectomy is curative and sufficient. From the anatomopathological study of the surgical sample, the correct diagnosis may be inferred.
