The Andrias davidianus has been known as a traditional Chinese medicine for a long time. Its blood is considered as a waste or by-product of the meat production industry. Although there are reports on isolation of the antimicrobial peptides from different resources, there are no reports of their isolation from Andrias davidianus blood. In this work, an antimicrobial peptide, andricin B, was isolated from the blood of Andrias davidianus by an innovative method in which the magnetic liposome adsorption was combined with reversed-phase high performance liquid chromatography...

PURPOSE: Olive pomace is a major waste product of olive oil production but remains rich in polyphenols and fibres. We measured the potential of an olive pomace-enriched biscuit formulation delivering 17.1 ± 4.01 mg/100 g of hydroxytyrosol and its derivatives, to modulate the composition and metabolic activity of the human gut microbiota. METHODS: In a double-blind, controlled parallel dietary intervention 62 otherwise healthy hypercholesterolemic (total plasma cholesterol 180-240 mg/dl) subjects were randomly assigned to eat 90 g of olive pomace-enriched biscuit (olive-enriched product, OEP) or an isoenergetic control (CTRL) for 8 weeks...

Current progress in neuroscience demonstrates that the brain is not an isolated organ and is influenced by the systemic environment and extracerebral processes within the body. In view of this new concept, blood and cerebrospinal fluid (CSF) are important body fluids linking extracerebral and intracerebral processes. For decades, substantial evidence has been accumulated indicating that CSF modulates brain states and influences behavior as well as cognition. This chapter provides an overview of how CSF directly modulates the function of different types of brain cells, such as neurons, neural stem cells, and CSF-contacting cells...

INTRODUCTION: Acute kidney injury is the sudden and almost complete loss of renal function with reduced glomerular filtration rate, and it occurs whenever the kidneys are unable to excrete metabolic waste products. METHOD: This randomized double-blinded clinical trial was performed in an intensive care unit (ICU) of a university educational hospital. After randomization with a random assigning table of numbers, patients were divided into two groups: an intervention group and a control group...

Maintaining a robust blood product supply is an essential requirement to guarantee optimal patient care in modern health care systems. However, daily blood product use is difficult to anticipate. Platelet products are the most variable in daily usage, have short shelf lives, and are also the most expensive to produce, test, and store. Due to the combination of absolute need, uncertain daily demand, and short shelf life, platelet products are frequently wasted due to expiration. Our aim is to build and validate a statistical model to forecast future platelet demand and thereby reduce wastage...

BACKGROUND AND OBJECTIVES: Infusion of by-products of red blood cell (RBC) storage-induced degradation as well as of the residual plasma proteins and the anticoagulant-preservative solution contained in units of stored blood serve no therapeutic purpose and may be harmful to some patients. Here, we describe a prototype of a gravity-driven system for bedside washing of stored RBCs. MATERIALS AND METHODS: Stored RBCs were diluted to 10% haematocrit (Hct) with normal saline, matching the conventional washing procedure...

Anemia is common in elective surgery and is an independent risk factor for morbidity and mortality. Historical management of anemia has focused on the use of allogeneic blood transfusion but this in itself is not without risk. It too has been independently associated with morbidity and mortality, let alone the costs and relative shortage of this resource. In recognition of this, patient blood management (PBM) shifts the focus from the product to the patient and views the patient's own blood as a resource that should be conserved and managed appropriately as a standard of care...

The blackberry seed was typically removed as a byproduct and waste from blackberry fruits for juices. Developing value-added utilization of berry seeds will significantly expand the market for berry products as well as improve benefit to berry producers. However, the research on blackberry seed is limited. The objective of this paper was to research antithrombotic mechanism of polysaccharides in blackberry seeds. Polysaccharides in blackberry seeds were extracted, purified and identified by high-performance gel permeation chromatography (HPSEC), gas chromatography (GC), fourier transform infrared (FT-IR) spectrometer and nuclear magnetic resonance spectra (NMR)...

Clearance of waste products from the brain is of vital importance. Recent publications suggest a potential clearance mechanism via paravascular channels around blood vessels. Arterial pulsations might provide the driving force for paravascular flow, but its flow pattern remains poorly characterized. In addition, the relationship between paravascular flow around leptomeningeal vessels and penetrating vessels is unclear. In this study, we determined blood flow and diameter pulsations through a thinned-skull cranial window...

Over the past decade substantial knowledge has been gained in understanding both the coagulopathy of trauma and the complications associated with aggressive crystalloid-based resuscitation. Balanced resuscitation, which includes permissive hypotension, limiting crystalloid use, and the transfusion of blood products in ratios similar to whole blood, has changed the previous standard of care. Prompt initiation of massive transfusion and the protocolled use of 1:1:1 product ratios have improved the morbidity and mortality of patients with trauma in hemorrhagic shock...

The production of antibodies is accompanied by a slight excess of synthesis of κ and λ immunoglobulin light chains; small amounts of them are released in the peripheral blood and can also be found in various body fluids, such as synovial fluid, cerebrospinal fluid, urine and saliva. They are rapidly filtered by the glomerulus and >99% are reabsorbed from the cells of the proximal convoluted tubule, making them present in the urine in only trace amounts. The production of an excess of protein without a reason or a specific function in a biological system is rare...

BACKGROUND: Although dialysis ameliorates uremia and fluid and electrolytes disorders, annual mortality rate remains high in dialysis population reflecting its shortcoming in replacing renal function. Unlike the normal kidney, dialysis causes dramatic shifts in volume and composition of body fluids and indiscriminate removal of vital solutes. Present study was undertaken to determine the impact of hemodialysis on plasma metabolites in end-stage renal disease (ESRD) patients. METHODS: 80 hemodialysis patients and 80 age/gender-matched healthy controls were enrolled in the study...

Coffee grounds, a waste by-product generated after making coffee, contains approximately 15% coffee oil which can be used as a raw material in cosmetics. Algae oil rich in docosahexaenoic acid (DHA) has been demonstrated to possess anticancer and anti-inflammation functions. The objectives of this study were to develop a gas chromatography-mass spectrometry (GC-MS) method for the determination of fatty acids in coffee oil and algae oil and prepare a nanoemulsion for studying its inhibition effect on ultraviolet A-induced skin damage in mice and growth of melanoma cells B16-F10...

Hemodialysis is a process of mass separation by a semipermeable membrane, utilized to cleanse blood from waste products retained in case of kidney failure. Traditionally, dialysis membranes have been classified based on composition and hydraulic conductance, creating the net differentiation between cellulosic versus non-cellulosic on one hand and low-flux versus high-flux on the other. With the evolution of biomaterials and improved spinning technology, new membranes have been introduced in the market with specific characteristics and refined individual properties...

Although radioiodine (131-I) can be used as treatment of hyperthyroidism for patients in hemodialysis, its use is limited and the experience is mainly related to differentiated thyroid carcinoma. We report a 58 years old female on hemodialysis with recurrent hyperthyroidism after propylthiouracil treatment. She was successfully treated with 131-I and four months after the intervention her euthyroid state was confirmed. We measured 131-I activity in blood, dialysate liquid and other waste products, as well as patient radiation exposure rates...

Blood vessels are essential for the distribution of oxygen, nutrients, and immune cells, as well as the removal of waste products. In addition to this conventional role as a versatile conduit system, the endothelial cells forming the innermost layer of the vessel wall also possess important signaling capabilities and can control growth, patterning, homeostasis, and regeneration of the surrounding organ. In the skeletal system, blood vessels regulate developmental and regenerative bone formation as well as hematopoiesis by providing vascular niches for hematopoietic stem cells...

Polybrominated diphenyl ethers (PBDEs) have been extensively used as flame retardants in consumer products. PBDEs rapidly bioaccumulate in the environment, food, wild animals and humans. In this review, we investigated the harmful effects of PBDEs on humans, especially in early life, and summarised the levels of PBDEs in human biological samples (breast milk, cord blood and placentas). In addition, we described the spatiotemporal distribution of PBDEs in this review. PBDE levels in breast milk, cord blood and placentas were generally higher in North America than in other regions, such as Asia, Europe, Oceania and Africa...

The amino acid L-glutamate serves a number of roles in the central nervous system, being an excitatory neurotransmitter, metabolite, and building block in protein synthesis. During pathophysiological events, where L-glutamate homeostasis cannot be maintained, the increased brain interstitial fluid concentration of L-glutamate causes excitotoxicity. A tight control of the brain interstitial fluid L-glutamate levels is therefore imperative, in order to maintain optimal neurotransmission and to avoid such excitotoxicity...

Ischemic disease caused by insufficient blood supply leads to a lack of oxygen and nutrients and a build-up of waste products in the affected tissue. Therapeutic angiogenesis, as a means to enhance perfusion of tissues with an inadequate blood supply, holds great promise for the treatment of ischemic disease. A wide range of factors that play a key role in physiological angiogenesis have been identified and trialed as pro-angiogenic agents. However, as yet pro-angiogenic treatments have failed to be translated clinically, owing to both lack of efficacy and safety concerns regarding the use of doses considerably larger than is typical present under physiological conditions...

The kidney requires a large number of mitochondria to remove waste from the blood and regulate fluid and electrolyte balance. Mitochondria provide the energy to drive these important functions and can adapt to different metabolic conditions through a number of signalling pathways (for example, mechanistic target of rapamycin (mTOR) and AMP-activated protein kinase (AMPK) pathways) that activate the transcriptional co-activator peroxisome proliferator-activated receptor-γ co-activator 1α (PGC1α), and by balancing mitochondrial dynamics and energetics to maintain mitochondrial homeostasis...
