A Meta-analysis on the Effectiveness of Trauma-informed Practice

This study looked at past research on trauma informed practice to analyze its effectiveness.. There is sufficient research portraying the helpfulness of the trauma-informed approach; however, there is little research on whether it is effective as a theoretical intervention. The study looked at how different trauma-informed interventions have helped in diminishing the effect of trauma on different populations. The populations considered in the analysis include: women that have experienced domestic violence, children, individuals with Post-Traumatic Stress Disorder (PTSD), and youth that reside in neighborhoods with high levels of crime. Since trauma-informed care is currently considered a broad theoretical framework for practice, with this meta-analysis, we aim to establish it as a concrete evidence-based practice

Design of an electroflotation system for the concentration and harvesting of freshwater microalgae

Microalgae are considered as one of the most promising alternatives for the integrated use of agro-industrial water residues and the production of metabolites of high industrial interest. This is due to algae can grow on wastewater which in turn can reduce the emission of nutrients to rivers and lakes. However, the greatest scientific-technological barrier is the concentration and separation of the biomass produced. There are several processes used at different levels (from laboratory to industrial scale) such as flocculation, centrifugation, flotation, etc. These can be very expensive or can (possibly) contaminate the biomass. Unlike the previous ones, electroflotation has been proposed as a cost-efficient method, nevertheless its final efficiency will depend heavily on the type of alga and culture medium. Taking into account the above, the present project aims to design an electroflotation system for the concentration and harvest of microalgae biomass. The effect of several factors (pH, time, voltage and distance between the electrodes) and for types of materials (Copper, Aluminium, Iron and Steel) on biomass recovery efficiency from a culture of Chlorella vulgaris UTEX 1803 was evaluated by the implementation of a Design of experiments (43 non-factorial design) using STATISTICA 7.0. Results show that, the materials with higher concentration efficiency were cooper and aluminium with 40 and 80% respectively, and the most relevant factors were distance between electrodes (1-2 cm), time (>20 min) and Voltage (>15V). In order to increase the efficiency of the overall process a new 43 experimental factorial design was proposed using as factors distance between electrodes, time, voltage and agitation. Results show that agitation positively affects the total efficiency until reaching a total concentration of the biomass (100%). It was found that a voltage close to 50V and a time greater than 25 min positively affect the final efficiency of the copper and aluminium electrodes, however aluminium has the highest efficiency (> 95%) compared to copper (<85%)

Neuroprotection, Photoperiod, and Sleep

After an acquired brain injury, responses that induce cell death are activated; however, neuroprotective mechanisms are also activated. The relation between these responses determines the destination of the damaged tissue. This relation presents variations throughout the day; numerous studies have shown that the onset of a stroke occurs preferably in the morning. In the rat, ischemia causes more damage when it is induced during the night. The damage caused by a traumatic brain injury (TBI), in the rat, varies depending on the time of day it is induced. Minor behavioral damage has been reported when the TBI occurs during the night, a period that coincides with the wakefulness of the rat. It also has been observed that sleep deprivation accelerates the recovery. Our group has documented that this is due, in part, to a difference in the degree of activation of cannabinergic, GABAergyc, and glutamatergic systems

The circular economy approach to improving CNP ratio in inland fishery wastewater for increasing algal biomass production

In this work, the capacity of wastewater from an inland fishery system in Colombia (Norte de Santander) was tested as culture medium for Chlorella sp. and Scenedesmus sp. Due to insufficient N and P concentrations for successful algae growth, the effect of wastewater replenishment with NO3, PO4, and Na2CO3 or NaHCO3 as a carbon source was analyzed using a three-factor nonfactorial response surface design. The results showed that the addition of NaNO3 (0.125 g/L), K2HPO4 (0.075 g/L), KH2PO4 (0.75 g/L), and NaHCO3 (0.5 and 2 g/L for Chlorella sp. and Scenedesmus sp. respectively) significantly increased the biomass of Chlorella sp. (0.87 g/L) and Scenedesmus sp. (0.83 g/L). Although these results show that the addition of other nutrients is not necessary (Na, Mg, SO4, Ca, etc.), it is still essential to determine the quality of the biomass produced in terms of its application as a feed supplement for fish production

Production of chlorella vulgaris biomass on uv-treated wastewater as an alternative for environmental sustainability on high-mountain fisheries

The sustained expansion of agricultural industry in Colombian high-mountain has led to an increased size of residues, especially untreated wastewater. This untreated water is an urgent matter for public and environmental health, not only by its nutrient concentration (composed especially of food residuals and feces) but also the presence of pathogens (virus, bacteria, etc.) which are discharged to the environment. The overall objective of this work is to evaluate the effect of UV-treated wastewater from a high-mountain fishery as culture media for the production of Chlorella vulgaris as a sustainable method for nutrient and water recirculation on the fishery production system. The UV-canal efficiency was evaluated by the implementation of an experimental factorial design (time, distance of the UV-lamps towards the canal, number of UV-lamps and the sample concentration) using STATISTICA 7.0 software. Results shown that time (3 to 5 minutes) and the number of lamps (3-4) of 15 Watts eliminate completely coliforms from the samples. After UV-treatment the resulting water was test as culture media for C. vulgaris production by the adjustment of C/N ratio (Sodium Carbonate/potassium nitrate) by the implementation of an experimental 23 factorial design. Results shown that higher nitrate concentrations (>0,22 g/L) and moderate carbonate concentrations (1 g/L) increase the final biomass concentration up to 4g/L in 20 days

Traditional Chinese Medicine Is Widely Used for Cardiovascular Disease

A review article by Hao et al. ( J Am Coll Cardiol 2017;69(24):2952–66) has had huge repercussions among those familiar with traditional Chinese medicine (TCM) in the international academic community. It evaluated the efficacy and safety of TCM for cardiovascular disease and the pharmacological effect of active TCM ingredients on the cardiovascular system and potential mechanisms. We have several comments: Firstly, we give a brief summary addressing nonpharmacotherapy in TCM, including acupuncture, moxibustion, Qigong, and Tai Chi. Secondly, we have added traditional antiarrhythmic drug–related randomized controlled trials to make the coverage more comprehensive. Lastly, we support the concept that research into, development of, and application of active ingredients is part of modern TCM

Fisheries wastewater as a sustainable media for the production of algae-based products

Colombian intensive fish production is concentrated mainly in the departments of the Andean Region, Amazon, and Orinoquía. These systems were characterized for being exploited mainly by family farming nuclei, which are dedicated exclusively to breeding and others with mixed systems. Currently, the sustainable development of this economic line depends on two factors: global warming and the consumption of resources (energy, fresh water, and protein). The rapid growth of this socio-economic line has led to the development of 3 critical restrictions: the demand for food for fish production, the high volume of fresh water needed and the high concentration of wastewater which must be disposed of safely. Sewage from closed fish farming systems has high levels of nitrogen and inorganic phosphorus dissolved in the systems. The primary responsibility for these high contents is the feed which contributes to the sustained increase in the concentration of organic waste and toxic compounds in aquatic systems. To make use of this wastewater, the use of these as a culture medium for microalgal production has been studied in order to generate metabolites of industrial interest from a low-cost culture medium. In this work, the necessary culture conditions for the biomass production of Scenedesmus obliquus, Chlorella vulgaris, Spirulina maxima, and Oscillatoria sp. in fish farming wastewater to produce pigments and total biomass are evaluated. The wastewater was obtained from an intensive fish farming company in El Zulia (Norte de Santander, Colombia). The medium was UV-sterilized (4 Lamps of 15W, 5 minutes). In order to optimize the production of biomass and pigments, the wastewater was adjusted with the addition of nitrogen, phosphorus, and carbon (K2HPO4 + NaNO3 + NaHCO3) According to the results, the residual water enriched with K2HPO4, NaNO3 and NaHCO3 presented the best culture conditions for obtaining carotenoids (in C. vulgaris and S. obliquus with values of 2.6 and 1.7% p/p respectively) and Phycobiliproteins in Spirulina maxima and Oscillatoria sp (10.9 and 11% p/p respectively). These results allow concluding that the residual water of fish systems is outlined as a suitable culture medium that can be used to produce metabolites of interest. Also, this culture medium must be enriched in order to increase the productivity of the system
