Traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease are three distinct neurological disorders that share common pathophysiological mechanisms involving neuroinflammation. One sequela of neuroinflammation includes the pathologic hyperphosphorylation of tau protein, an endogenous microtubule-associated protein that protects the integrity of neuronal cytoskeletons. Tau hyperphosphorylation results in protein misfolding and subsequent accumulation of tau tangles forming neurotoxic aggregates. These misfolded proteins are characteristic of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease and can lead to downstream neuroinflammatory processes, including assembly and activation of the inflammasome complex. Inflammasomes refer to a family of multimeric protein units that, upon activation, release a cascade of signaling molecules resulting in caspase-induced cell death and inflammation mediated by the release of interleukin-1β cytokine. One specific inflammasome, the NOD-like receptor protein 3, has been proposed to be a key regulator of tau phosphorylation where it has been shown that prolonged NOD-like receptor protein 3 activation acts as a causal factor in pathological tau accumulation and spreading. This review begins by describing the epidemiology and pathophysiology of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease. Next, we highlight neuroinflammation as an overriding theme and discuss the role of the NOD-like receptor protein 3 inflammasome in the formation of tau deposits and how such tauopathic entities spread throughout the brain. We then propose a novel framework linking traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease as inflammasomedependent pathologies that exist along a temporal continuum. Finally, we discuss potential therapeutic targets that may intercept this pathway and ultimately minimize long-term neurological decline.

Potential Changes in Net Primary Productivity and Carbon Input of Periurban Agroecosystems Treated with Biosolids in Buenos Aires, Argentina

引用

Pedosphere 2016年第1期26卷 98-107页

作者： gabriela CIVEIRA Institute of soil science Instituto Nacional de Tecnología Agropecuaria

Biosolids application in periurban agroecosystems could mitigate climate change by sequestering C, while improving plant net primary production(NPP). Monitoring NPP is useful for studying ecological responses to human management. The values of NPP and C input in periurban agroecosystems are insufficient or missing. The objective was to use local databases to estimate NPP and C input in periurban areas(south, north and west) of Buenos Aires City, Argentina, using different biosolids application scenarios(low and high effects). The NPP varied with crop and vegetable types(P s) and wheat(Triticum aestivum) presenting the highest production, soybean(Glycine max) medium and sunflower(Helianthus annuus) the lowest. Tomato(Lycopersicon esculentum Mill.) presented the highest production in the south area(La Plata). West and north areas, where Vertic and Typic Argiudolls are the main soils, presented the lowest NPP and C input. According to the low and high effect scenarios,only vegetables presented significant differences(P s. Vegetables contributed with the highest proportion(> 70%) to NPP in both projected scenarios. For both scenarios, average C input by crops and vegetables presented similar proportions. Biosolids addition in periurban agroecosystems could be a viable practice to elevate NPP and C input.

Challenges in transplantation for alcoholic liver disease

引用

World Journal of Gastroenterology 2014年第25期20卷 8033-8039页

作者： gabriela A Berlakovich Department of surgery Division of Transplantation Medical University of ViennaVienna A-1090Austria

Transplantation for the treatment of alcoholic cirrhosis is more controversially discussed than it is for any other indication. The crucial aspect in this setting is abstinence before and after liver transplantation. We established pre-transplant selection criteria for potential transplant candidates. Provided that the underlying disease can be treated, there is no reason to withhold liver transplantation in a patient suffering from alcoholic cirrhosis. Evaluation of the patient by a multidisciplinary team, including an addiction specialist, is considered to be the gold standard. However, several centers demand a specified period of abstinence- usually 6 mo- irrespective of the specialist's assessment. The 6-mo rule is viewed critically because liver transplantation was found to clearly benefit selected patients with acute alcoholic hepatitis; the benefit was similar to that achieved for other acute indications. However, the discussion may well be an academic one because the waiting time for liver transplantation exceeds six months at the majority of centers. The actual challenge in liver transplantation for alcoholic cirrhosis may well be the need for lifelong post-transplant follow-up rather than the patient's pretransplant evaluation. A small number of recipients experience a relapse of alcoholism; these patients are at risk for organ damage and graft-related death. Posttransplant surveillance protocols should demonstratealcohol relapse at an early stage, thus permitting the initiation of adequate treatment. Patients with alcoholic cirrhosis are at high risk of developing head and neck, esophageal, or lung cancer. The higher risk of malignancies should be considered in the routine assessment of patients suffering from alcoholic cirrhosis. Tumor surveillance protocols for liver transplant recipients, currently being developed, should become a part of standard care; these will improve survival by permitting diagnosis at an early stage. In conclusion, the key factor

Application of platelet-rich plasma with stem cells in bone and periodontal tissue engineering

Presently, there is a high paucity of bone grafts in the United states and worldwide. Regenerating bone is of prime concern due to the current demand of bone grafts and the increasing number of diseases causing bone loss. Autogenous bone is the present gold standard of bone regeneration. However, disadvantages like donor site morbidity and its decreased availability limit its use. Even allografts and synthetic grafting materials have their own limitations. As certain specific stem cells can be directed to differentiate into an osteoblastic lineage in the presence of growth factors(GFs), it makes stem cells the ideal agents for bone ***, platelet-rich plasma(PRP), which can be easily isolated from whole blood, is often used for bone regeneration, wound healing and bone defect repair. When stem cells are combined with PRP in the presence of GFs, they are able to promote osteogenesis. This review provides in-depth knowledge regarding the use of stem cells and PRP in vitro, in vivo and their application in clinical studies in the future.

In this paper we give a survey about the Roper-suffridge extension operator and the developments in the theory of univalent mappings in several variables to which it has led. We begin with the basic geometric properties (most of which now have a number of different proofs)and discuss relations with the theory of Loewner chains and generalizations and modifications of the operator, some of which are very recent.

Detection and determination of undeclared synthetic caffeine in weight loss formulations using HPLC-DAD and UHPLC-Ms/Ms

引用

Journal of Pharmaceutical Analysis 2018年第6期8卷 366-372页

Caffeine is present in products marketed for weight loss, with the purpose of increasing thermogenesis and lipid metabolism. The dosage declared by the product manufacturer, or even its presence, is not always correctly described on the label. This work aimed to investigate the undeclared synthetic caffeine in weight loss formulations by a high-performance liquid chromatography with diode array detection(HPLC-DAD) method. From one hundred products purchased through Brazilian e-commerce, seventeen contained caffeine, either naturally or synthetically added to formulation. The caffeine-containing samples were confirmed by an ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-Ms/Ms) method, and adulteration was clearly proven in five products. The content highest caffeine contained 448.8 mg per dose. Other irregularities were also found; nevertheless, the most serious was the addition of synthetic drugs without asking the consumers. Additional drugs expose the consumer to more possible side-effects as well as deleterious drug interactions. Intentional adulteration with any unlabeled substance is typically motivated by a desire to increase or alter the claimed effect of the marketed product to gain a commercial advantage.
