BACKGROUND: The safety and efficacy of continuous, multiday, automated glycaemic management has not been tested in outpatient studies of preadolescent children with type 1 diabetes. We aimed to compare the safety and efficacy of a bihormonal bionic pancreas versus conventional insulin pump therapy in this population of patients in an outpatient setting. METHODS: In this randomised, open-label, crossover study, we enrolled preadolescent children (aged 6-11 years) with type 1 diabetes (diagnosed for ≥1 year) who were on insulin pump therapy, from two diabetes camps in the USA...

REVIEW
Sudesna Chatterjee, Melanie J Davies
The last 90 years have seen considerable advances in the management of type 1 and type 2 diabetes. Prof MacLean of Guy's Hospital wrote in the Postgraduate Medical Journal in 1926 about the numerous challenges that faced patients and their healthcare professionals in delivering safe and effective diabetes care at that time. The discovery of insulin in 1922 heralded a new age in enabling long-term glycaemic control, which reduced morbidity and mortality. Thirty years later, the first oral agents for diabetes, the biguanides and sulfonylureas, appeared and freed type 2 patients from having to inject insulin following diagnosis...

REVIEW
Silke V Niederhaus
PURPOSE OF REVIEW: The present article aims to review the current state of diabetes, including its treatment options, and highlight current issues in pancreas transplantation. RECENT FINDINGS: Compared with other areas of transplantation, pancreas transplant/transplantation alone in the absence of kidney disease remains a relatively small field. As a consequence, reported new research articles are few in number, and often data regarding pancreas transplant/transplantation alone are mixed in with simultaneous kidney-pancreas and pancreas after kidney transplantation, which are covered separately...

OBJECTIVE: The objective of the study was to assess urinary biomarkers of renal injury for their individual or collective ability to predict Worsening renal function (WRF) in patients with acutely decompensated heart failure (ADHF). METHODS: In a prospective, blinded international study, 87 emergency department (ED) patients with ADHF were evaluated with biomarkers of cardiac stretch (B type natriuretic peptide [BNP] and its amino terminal equivalent [NT-proBNP], ST2), biomarkers of renal function (creatinine, estimated glomerular filtration rate [eGFR]) and biomarkers of renal injury (plasma neutrophil gelatinase associated lipocalin [pNGAL], urine kidney injury molecule-1 [KIM-1], urine N-acetyl-beta-D-glucosaminidase [NAG], urine Cystatin C, urine fibrinogen)...

BACKGROUND: The safety and effectiveness of automated glycemic management have not been tested in multiday studies under unrestricted outpatient conditions. METHODS: In two random-order, crossover studies with similar but distinct designs, we compared glycemic control with a wearable, bihormonal, automated, "bionic" pancreas (bionic-pancreas period) with glycemic control with an insulin pump (control period) for 5 days in 20 adults and 32 adolescents with type 1 diabetes mellitus...

In order to begin to study the structural and functional mechanisms of olfactory receptors, methods for milligram-scale purification are required. Here we demonstrate the production and expression of a synthetically engineered human olfactory receptor hOR17-4 gene in a stable tetracycline-inducible mammalian cell line (HEK293S). The olfactory receptor gene was fabricated from scratch using PCR-based gene-assembly, which facilitated codon optimization and attachment of a 9-residue bovine rhodopsin affinity tag for detection and purification...

Bionic Kidney is a project still in progress which aims at replacing all renal functions, which has been carried out in an ideal attempt to improve the overall results of Renal Replacement Therapy. It contains all the requisites for a complete rehabilitation from Uremia. As a futuristic mini-device implanted in the body, it should be a reliable support to Transplantation performance, considering the scarcity of kidney donors.

1. N-methyl-D-aspartate (NMDA) receptor channels are blocked by intracellular Mg2+ in a voltage-dependent manner. Amino acid residues positioned at or near the narrow constriction that interact with intracellular Mg2+ were identified in recombinant NR1-NR2A channels expressed in Xenopus oocytes or human embryonic kidney (HEK) 293 cells. 2. In the absence of extracellular Ca2+, the block of wild-type channel by intracellular Mg2+ measured using macroscopic currents showed a voltage dependence (delta) of around 0...

1. The voltage-dependent block of N-methyl-D-aspartate (NMDA) receptor channels by extracellular Mg2+ is a critical determinant of its contribution to CNS synaptic physiology. The function of the narrow constriction of the channel in determining the block was investigated by analysing the effects of a set different amino acid substitutions at exposed residues positioned at or near this region. NMDA receptor channels, composed of wild-type and mutant NR1- and NR2A-subunits, were expressed in Xenopus oocytes or human embryonic kidney (HEK) 293 cells...

Ferrous based, corrosion resistant amorphous alloys supported the adhesion and growth of cultured chick neuronal cells, human marrow stromal cells (presumptive osteoblasts), bovine aortal endothelial cells, and hamster kidney fibroblasts. Alloys of compositions Fe60Ni10Cr10P13C7, Fe70Cr10P13C7, and Fe70Cr10P13B7 were found to be suitable. In contrast the crystalline form of these alloys was markedly less effective. Outgrowth of neurites from neuronal cells was promoted by precoating the metal surface with either laminin or neurite promotion factor...

When a lizard loses its tail, a new caudal appendage soon grows to replace the one that is missing. But when a human loses a kidney, severs a peripheral nerve or worse, the spinal cord, that organ is lost forever. Such at least is conventional thinking. But imagine that the victim of an industrial accident with a paralyzed hand could achieve new levels of function by inducing axonal regrowth through a synthetic nerve guidance channel; or that a Parkinsonian patient's symptoms could be relieved by implanting in his brain neural tissue encased in a selectively permeable polymer envelope; or that the inexorable progression of the vascular complications of juvenile diabetes could be stopped, even reversed, by a membrane-protected xenograft of insulin-producing tissue...

COMPARATIVE STUDY
E S Bücherl
The state of the art in the development of artificial heart research based on more than 100 own animal experiments and information from the other groups working in the same field is laid out. Consideration is given to a variety of special problems. The use of biomaterials (blood compatibility and mechanical strength and durability), the flow pattern in the pumps (clot formation), and special hemodynamical effects are discussed as well as different driving systems and percutane energy transmission (avoidance of infection)...

E A Friedman
An attempt to prophesy the future of home hemodialysis is based on anticipated near and long term technological improvements. Dialysis treatments will become shorter, due to pressure filtration, while extracting molecules in the 300 to 3000 dalton weight range through more permeable membranes. Portable and wearable dialysis systems will increase patient mobility. By the 21st century, implantable bionic kidneys and perfect host tolerance to renal allografts and xenografts will relegate home hemodialysis to history texts...
