    The poultry industry is growing annually due to high commercial demand. This activity needs a high amount of water for its processes, which after being used must be treated properly to be discharged into the sewer. For this reason, we have investigated the potential of moringa seeds to treat wastewater from a Poultry Profit Center. After processing seeds, the extract obtained was tested, taking turbidity as an initial indicator to determine the optimal dosage. Four samples were then analyzed in a certified laboratory. Of these, one sample contained untreated water and three samples contained water treated with moringa extract at different concentrations (10mg/l, 15mg/l, and 20mg/l), all from the pools of the Poultry Profit Center; to evaluate the efficiency of the formulation in the removal of BOD5, COD, SST, coliforms, ammonia, oils, and fats. The results showed high removal efficiency, indicating improved water quality.La industria avícola crece anualmente por su alta demanda comercial. Esta actividad necesita grandes cantidades de agua para sus procesos, que después de ser usada debe tratarse adecuadamente para poder ser vertida al alcantarillado. Por esta razón, hemos investigado el potencial de las semillas de moringa para tratar las aguas residuales de un centro de beneficio avícola. Tras procesar estas semillas, el extracto obtenido fue testeado, tomando como indicador inicial la turbidez, para determinar la dosis óptima. Luego se analizaron cuatro muestras en un laboratorio certificado. De estas, una muestra contenía agua sin tratamiento y tres, agua tratada con el extracto de moringa a distintas concentraciones (10 mg/l, 15 mg/l y 20 mg/l), todas extraídas de las pozas del centro de beneficio avícola, con el propósito de evaluar la eficiencia de la formulación en la remoción de DBO5, DQO, SST, coliformes, amoníaco, aceites y grasas. Los resultados demostraron gran eficiencia de remoción y la obtención de agua de calidad mejorada

    Central hypoventilation syndrome (CHS) is a rare condition resulting from damage to the respiratory centers in the central nervous system (CNS). It can be congenital or acquired and can cause hypoventilation, inadequate gas exchange, and respiratory failure, often during sleep but sometimes even while awake. CHS can lead to respiratory failure and life-threatening complications if not identified promptly. In this report, we present a rare case of a patient with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), who developed CHS likely due to an opportunistic infection by cytomegalovirus (CMV) and varicella zoster virus (VZV), manifesting as a lesion in the medullary respiratory nuclei. After treatment with ganciclovir, the patient showed clinical improvement, and his medullary lesion resolved

    To evaluate the potential effects of medications with central nervous system (CNS) activity on cognitive function and fatigue in multiple sclerosis (MS), we performed a retrospective analysis of medication use among 70 subjects with MS who were participating in a clinical trial for evaluation of the effects of yoga and exercise programs on cognition and fatigue. Among these MS subjects, 74% were taking at least one potentially CNS-active medication. These 70 subjects were divided into two groups: those taking at least one CNS-active medication (n = 52) and those not on any medications with potential CNS activity (n = 18). We compared assessments of cognitive function and fatigue using an analysis of covariance. MS subjects on CNS-active medication had greater impairment on measures of processing speed, sustained attention, and fatigue than those not on these medications. While these findings do not establish a causal relationship between medication use and cognitive impairment and fatigue, the data indicate that researchers need to control for use of CNS-active medications when conducting studies of cognitive impairment and fatigue in MS subjects

    Energy saving is a global priority, as it is helping both energy and environmental sustainability by reducing CO2 emissions. The search for new energy solutions is therefore necessary. In the Mediterranean climate, resources are generally scarce, and all energy sources need to be explored, including biomass from agricultural or industrial waste. There is a clear upward trend in date worldwide production, having doubled its world production in the last 10 years, and this trend is particularly relevant for Mediterranean climate countries, especially in North Africa and nearby countries. This study analyzes the properties associated with the date seed (Phoenix dactylifera L.) to evaluate its suitability and viability as a new biofuel. Specifically, the viability of replacing the existing gas boiler in a university building in the south of Spain with a system of biomass boilers using this biomass was analyzed as a case study. The results reveal that this biomass has HHV values very similar to those of other biomass sources, 19.121 MJ/kg. With the replacement of the gas boiler by a biomass that uses the date seed, a reduction of 95 tons of CO2 per year is obtained and an economic saving of more than 66% is achieved. In short, this work opens new perspectives for the use of this biomass of date seed in boilers and it is an efficient solution for large public buildings such as the buildings of Mediterranean climate universities

    ObjectivesThis trial examined the efficacy of a stress management program in reducing neuroimaging markers of multiple sclerosis (MS) disease activity.MethodsA total of 121 patients with relapsing forms of MS were randomized to receive stress management therapy for MS (SMT-MS) or a wait-list control condition. SMT-MS provided 16 individual treatment sessions over 24 weeks, followed by a 24-week post-treatment follow-up. The primary outcome was the cumulative number of new gadolinium-enhancing (Gd+) brain lesions on MRI at weeks 8, 16, and 24. Secondary outcomes included new or enlarging T2 MRI lesions, brain volume change, clinical exacerbation, and stress.ResultsSMT-MS resulted in a reduction in cumulative Gd+ lesions (p = 0.04) and greater numbers of participants remained free of Gd+ lesions during the treatment (76.8% vs 54.7%, p = 0.02), compared to participants receiving the control treatment. SMT-MS also resulted in significantly reduced numbers of cumulative new T2 lesions (p = 0.005) and a greater number of participants remaining free of new T2 lesions (69.5% vs 42.7%, p = 0.006). These effects were no longer detectable during the 24-week post-treatment follow-up period.ConclusionsThis trial indicates that SMT-MS may be useful in reducing the development of new MRI brain lesions while patients are in treatment.Classification of evidenceThis study provides Class I evidence that SMT-MS, a manualized stress management therapy program, reduced the number of Gd+ lesions in patients with MS during a 24-week treatment period. This benefit was not sustained beyond 24 weeks, and there were no clinical benefits.Trial registrationClinicalTrials.gov, number NCT00147446

    The Perceived Deficits Questionnaire (PDQ) is a part of the Multiple Sclerosis (MS) Quality of Life Inventory that assesses self-perceived cognitive difficulties. We used baseline data from 49 MS subjects participating in a clinical trial to evaluate the correlation of the PDQ with two measures of cognitive impairment, the Paced Auditory Serial Addition Test (PASAT) and the California Verbal Learning Test, 2nd edition (CVLT-II), total score, and one measure of depression, the Beck Depression Inventory-Amended (BDI-IA). The PDQ correlated significantly (r = 0.42; 95% confidence interval [CI], 0.15 to 0.62; p = 0.003) with the BDI-IA scores but not with either the PASAT (r = - 0.22; 95% CI, - 0.48 to 0.06; p = 0.2) or the CVLT-II total (r = - 0.17; 95% CI, -0.43 to 0.12; p = 0.25). A subset of 38 of these subjects who scored worse than 0.5 standard deviation below the mean on the PASAT or CVLT-II received a more extensive neuropsychological battery of tests. No significant correlations were found between any of these tests and the PDQ. These results suggest that self-perceived cognitive dysfunction relates more to depression than to objective cognitive dysfunction

    Background. Fatigue is the most common symptom in people with multiple sclerosis (MS). Poor sleep also occurs in this population. Objective. The objective of this study was to determine the relationship between fatigue and sleep quality in people with MS and cognitive impairment. Method. This cross-sectional study assessed relationships among fatigue, assessed with the Modified Fatigue Impact Scale (MFIS) and the Fatigue Severity Scale (FSS), sleep quality assessed with the Pittsburg Sleep Quality Index (PSQI), and demographics in 121 people with MS and cognitive impairment. Results. Fatigue was significantly correlated with poor sleep quality (MFIS: = 15.60, < 0.01; FSS: = 12.09, < 0.01). FSS scores were also significantly correlated with the PSQI subscore for daytime dysfunction and MFIS scores were significantly correlated with disability, age, and the PSQI subscores for sleep quality, sleep duration, and daytime dysfunction. Conclusions. This study demonstrates a relationship between fatigue and sleep quality in individuals with MS and cognitive impairment
