Blood substitute

Suman Mishra, Jinny Willis, Juliet Ansell, John Alexander Monro
Kiwifruit is a carbohydrate food of low glycaemic potency which could potentially be exchanged for starch-based foods in management of postprandial glycaemia. The effect of equicarbohydrate partial exchange of kiwifruit varieties 'Hayward' green (GR) and 'Zesy002' (SunGold; SG) for a starchy wheat-based breakfast cereal (WB) on the characteristics of the postprandial glycaemic response and satiety was therefore determined. A total of twenty non-diabetic subjects (mean age 36 years; mean BMI 24·5 kg/m(2)) consumed four meals, each containing 40 g available carbohydrate, in random order, after an overnight fast...

: Coconut and palm oils which were the major sources of dietary fats for centuries in most of West Africa have been branded as unhealthy highly saturated fats. Their consumption has been peddled to supposedly raise the level of blood cholesterol, thereby increasing the risk of coronary heart disease. This adverse view has led to a reduction in their consumption in West Africa and they have been substituted for imported vegetable oils. Recent information however, indicates some beneficial effects of these oils particularly their roles in nutrition, health and national development...

BACKGROUND: Growth hormone (GH) has many direct and indirect actions and roles including substrate regulation and priming of some cells of the immune system, and the expected aspects of growth and repair. Different concentrations in human body fluids reflect the exercise-induced growth hormone response (EIGR) after exercise. In populations such as elite athletes, the invasive nature of venous sampling is poorly accepted. Thus, this study examines possible viable alternatives such as urine and saliva samples and the GH concentration...

Intracerebral hemorrhage (ICH) remains a cause of death in hematologic malignancies. Asparaginase represents a key agent in the treatment of acute lymphoblastic leukemia (ALL). The toxicity of asparaginase includes coagulopathy such as thrombotic or bleeding tendency. We report a case of fatal cerebral hemorrhage in a 12-year-old girl treated for ALL. Cerebral hemorrhage occurred after three injections of L-asparaginase. The patient presented with hypofibrinogenemia (0.36g/L), associated with thrombocytopenia (24,000/mm(3))...

Novel avian H7N9 virus emerged in China in 2013 resulting in a case fatality rate of around 39% and continues to pose zoonotic and pandemic risk. Amino acid substitutions in PB2 protein were shown to influence the pathogenicity and transmissibility of H7N9 following experimental infection of ferrets and mice. In this study, we evaluated the role of amino acid substitution PB2-627K or compensatory changes at PB2-591K and PB2-701N, on the tropism and replication competence of H7N9 viruses for human and swine respiratory tracts using ex vivo organ explant cultures...

Angiotensin I-converting enzyme (ACE) hydrolyzes numerous peptides and is a critical participant in blood pressure regulation and vascular remodeling. Elevated tissue ACE levels are associated with increased risk for cardiovascular and respiratory disorders. Blood ACE concentrations are determined by proteolytic cleavage of ACE from the endothelial cell surface, a process that remains incompletely understood. In this study, we identified a novel ACE gene mutation (Arg532Trp substitution in the N domain of somatic ACE) that increases blood ACE activity 7-fold and interrogated the mechanism by which this mutation significantly increases blood ACE levels...

Recently, there has been an increase in the consumption of designer drugs, substances aimed at producing psychoactive, energizing, euphoric or anesthetic effects. Designer drugs are substitutes of actual narcotics, whose possession is banned under Polish law according to the Act of 29 July 2005. The latest reports suggest that the number of synthetic psychoactive substances is increasing. In the span of 2012, a total of 28 new synthetic cannabinoids were discovered in member states of the European Union. Synthetic psychoactive substances appear in different forms on the market: tablets (often very colourful and interestingly-shaped), seeds, dried product (sprayed with synthetic substance and redried), crystals or powder...

Antimicrobial peptides (AMPs) are innate molecules that are found in a wide variety of species ranging from bacteria to humans. In recent years, excessive usage of antibiotics resulted in development of multi-drug resistant pathogens which made researchers to focus on AMPs as potential substitute for antibiotics. Lily type mannose-binding lectin is an extended super-family of structurally and evolutionarily related sugar binding proteins. These lectins are well-known AMPs which play important roles in fish defense mechanism...

Due to the significantly improved outcome and quality of life of patients with different tumor entities after cytoreductive surgery (CRS) and HIPEC, there is an increasing number of centers performing CRS and HIPEC procedures. As this procedure is technically challenging with potential high morbidity and mortality, respectively, institutional experience also in the anesthetic and intensive care departments is essential for optimal treatment and prevention of adverse events. Clinical pathways have to be developed to achieve also good results in more comorbid patients with border line indications and extensive surgical procedures...

Both type I interferon (IFN-I) and CD40 play a significant role in various infectious diseases, including malaria and autoimmune disorders. CD40 is mostly known to function in adaptive immunity, but previous observations of elevated CD40 levels early after malaria infection of mice led us to investigate its roles in innate IFN-I responses and disease control. Using a Plasmodium yoelii nigeriensis N67 and C57BL/6 mouse model, we showed that infected CD40-/- mice had reduced STING and serum IFN-β levels day-2 post infection, higher day-4 parasitemia, and earlier deaths...

BACKGROUND: Nocturnal leg cramps are painful, involuntary muscle contractions commonly seen in elderly. While mostly harmless, they can severely impair quality of life and often disrupt sleep. Adverse drug effects may be responsible for a fraction of nocturnal leg cramps but often go unrecognized, resulting in additional prescribing intended to deal with adverse effects that might be better addressed by reduction, substitution, or discontinuation of the offending agent. CASE PRESENTATION: An 87 year old female presented as outpatient in family medicine with nocturnal leg cramps which had been present for five years and increasingly burdened her quality of life...
