Topical insulin has been shown to promote wound healing in various studies. Considering the absence of a systematic review and quantitative synthesis on the same, the present study was carried out. Using an appropriate search strategy, electronic databases were searched for randomized controlled trials that have compared topical application of insulin in wounds with normal saline. Standardize mean differences were calculated for the following outcome measures: healing rate of ulcers/wound, percent granulation tissue growth, micro vessel density, time to heal, wound area and ulcer severity score...

Inspissated bile syndrome (IBS) is a rare condition in which thick intraluminal bile, including bile plugs, sludge, or stones, blocks the extrahepatic bile ducts in an infant. A 5-week-old female infant was admitted for evaluation of jaundice and acholic stool. Diagnostic tests, including ultrasound sonography, magnetic resonance cholangiopancreatography, and a hepatobiliary scan, were not conclusive. Although the diagnosis was unclear, the clinical and laboratory findings improved gradually on administration of urodeoxycholic acid and lipid emulsion containing omega-3 polyunsaturated fatty acids (PUFAs) for 3 weeks...

BACKGROUND: Hydrogen-rich saline can selectively scavenge reactive oxygen species (ROS) and protect brain against ischemia reperfusion (I/R) injury. Endoplasmic reticulum stress (ERS) has been implicated in the pathological process of cerebral ischemia. However, very little is known about the role of hydrogen-rich saline in mediating pathophysiological reactions to ERS after I/R injury caused by cardiac arrest. METHODS: The rats were randomly divided into three groups, sham group (n=30), ischemia/reperfusion group (n=40) and hydrogen-rich saline group (n=40)...

A new wave of portable biosensors allows frequent measurement of health-related physiology. We investigated the use of these devices to monitor human physiological changes during various activities and their role in managing health and diagnosing and analyzing disease. By recording over 250,000 daily measurements for up to 43 individuals, we found personalized circadian differences in physiological parameters, replicating previous physiological findings. Interestingly, we found striking changes in particular environments, such as airline flights (decreased peripheral capillary oxygen saturation [SpO2] and increased radiation exposure)...

The idea of incorporating a mouthrinse with normal tooth brushing could be a useful adjunct to oral hygiene. Despite the principle nature of the toothpaste vehicle, most alcohol-based chemical plaque-control agents have been evaluated and later formulated in the mouthrinse vehicle. The current study was aimed to investigate the persistence of antimicrobial action and plaque inhibitory properties of a new alcohol-free mouthrinse when compared with positive control, chlorhexidine 0.12% and placebo control, physiologic saline solution mouthrinses...

Delocalized lipophilic cations such as tri- and tetra-arylphosphonium are able to diffuse across the mitochondrial membrane, which allows them to selectively accumulate in cells with a high transmembrane potential (ΔΨm ). The mitochondrial membrane potential of cancer cells and cardiomyocytes has been reported to be significantly higher than that of normal epithelial cells. This feature can be exploited for the selective accumulation of phosphonium derivatives for the purposes of molecular imaging using radionuclides...

: Glucose-dependent insulinotropic polypeptide (GIP) beyond its insulinotropic effects may regulate post-prandial lipid metabolism. While the insulinotropic action of GIP is known to be impaired in type 2 diabetes mellitus (T2DM), its adipogenic effect is unknown. We hypothesised GIP is anabolic in human subcutaneous adipose tissue (SAT) promoting triacylglycerol (TAG) deposition through re-esterification of non-esterified fatty acids (NEFA) and this effect may differ according to obesity status or glucose tolerance...
