Curcumin (Cur) has potent antitumor activity; however, its clinical use is limited due to its hydrophobicity and instability at physiological pH. In this work, Cur was incorporated into MPEG2K-P(CL-co-LLA) micelles to form the Cur-loaded micelles with drug loadings from 4.72% to 35.21% depending on the ratios of drug to MPEG2K-P(CL-co-LLA). The resulting Cur-loaded micelles were spherical with mean hydrodynamic diameters in the range of 28.8 to 58.6 nm, having excellent water-solubility and good stability at pH 7...

Under field conditions, plants are exposed to cycles of dehydration and rehydration during their lifespan. In this study, we hypothesized that sugarcane plants previously exposed to cycles of water deficits will perform better than plants that have never faced water deficits when both are subjected to low water availability. Sugarcane plants were grown in a nutrient solution and exposed to one (1WD), two (2WD) or three (3WD) water deficit cycles. As the reference, plants were grown in a nutrient solution without adding polyethylene glycol...

BACKGROUND: The World Health Organization (WHO) recommends rapid intravenous rehydration, using fluid volumes of 70-100mls/kg over 3-6 h, with some of the initial volume given rapidly as initial fluid boluses to treat hypovolaemic shock for children with acute gastroenteritis (AGE) and severe dehydration. The evidence supporting the safety and efficacy of rapid versus slower rehydration remains uncertain. METHODS: We conducted a systematic review of randomised controlled trials (RCTs) on 11th of May 2017 comparing different rates of intravenous fluid therapy in children with AGE and moderate or severe dehydration, using standard search terms...

Sweetpotato is a significant crop which is widely cultivated particularly in the developing countries with high and stable yield. However, drought stress is a major limiting factor that antagonistically influences the crop's productivity. Dehydration stress caused by drought causes aggregation of reactive oxygen species (ROS) in plants, and aldose reductases are first-line safeguards against ROS caused by oxidative stress. In the present study, we generated transgenic sweetpotato plants expressing aldose reductase, XvAld1 isolated from Xerophyta viscosa under the control of a stress-inducible promoter via Agrobacterium-mediated transformation...

The worldwide switch to inactivated polio vaccines (IPV) is a key component of the overall strategy to achieve and maintain global polio eradication. To this end, new IPV vaccine delivery systems may enhance patient convenience and compliance. In this work, we examine NanopatchTM (a solid, polymer micro-projection array) which offers potential advantages over standard needle/syringe administration including intradermal delivery and reduced antigen doses. Using trivalent IPV (tIPV) and a purpose-built evaporative dry-down system, candidate tIPV formulations were developed to stabilize tIPV during the drying process and upon storage...

Aims: The pseudo-cereal quinoa has an outstanding nutritional value. Seed germination is unusually fast, and plant tolerance to salt stress exceptionally high. Seemingly all seeds harbor bacterial endophytes. This work examines mitogen-activated protein kinase (MAPK) activities during early development. It evaluates possible contribution of endophytes to rapid germination and plant robustness. Methods: MAPK activities were monitored in water- and NaCl-imbibed seeds over a 4-h-period using an immunoblot-based approach...

BACKGROUND: Fluid management is a major factor determining perioperative outcome, yet in reality, fluid administration practice is variable. Thirst however, is a highly sensitive and reliable indicator of fluid deficits. We explored the use of thirst sensation to trigger i.v. fluid boluses to guide individualized fluid management. METHODS: We performed a randomised double crossover trial on 16 healthy male volunteers, of mean age 31 yr and BMI 24.4 kg m-2. Twice, after administrations of oral furosemide (40 mg) and 12 h of oral fluid restriction, participants received a 4-h i...

INTRODUCTION: Diarrhoeal disease is the second leading cause of death in children under 5 years globally, killing 525 000 annually. Australian Aboriginal and Torres Strait Islander (hereafter Aboriginal) children suffer a high burden of disease. Randomised trials in other populations suggest nitazoxanide accelerates recovery for children with Giardia, amoebiasis, Cryptosporidium, Rotavirus and Norovirus gastroenteritis, as well as in cases where no enteropathogens are found. METHODS AND ANALYSIS: This double blind, 1:1 randomised, placebo controlled trial is investigating the impact of oral nitazoxanide on acute gastroenteritis in hospitalised Australian Aboriginal children aged 3 months to <5 years...

BACKGROUND: Although acute diarrhea often leads to acute dehydration and electrolyte imbalance, children with diarrhea also suffer long term morbidity, including recurrent or prolonged diarrhea, loss of weight, and linear growth faltering. They are also at increased risk of post-acute mortality. The objective of this systematic review was to identify interventions that address these longer term consequences of diarrhea. METHODS: We searched Medline for randomized controlled trials (RCTs) of interventions conducted in low- and middle-income countries, published between 1980 and 2016 that included children under 15 years of age with diarrhea and follow-up of at least 7 days...

Freeze-drying (FD) has utility for phytonutrient screening but its reliability for starch measurements is unclear. The impact of FD was tested on total (TS), digestible (DS) and resistant starch (RS) for four potato varieties (PC Red, GG Red, GG Yellow, and Dolbec Yellow). The treatments included: (a) tubers boiled and then cooled for 1h at room temperature (RT) (control; Treatment 1) and 24h at 4°C; (b) tubers boiled and then cooled for 1h at RT with subsequent FD (Treatment 2); and (c) raw tubers that underwent FD, then were rehydrated, boiled, and cooled for 1h at RT (Treatment 3)...

Although most cases of acute gastroenteritis require minimal medical intervention, severe dehydration and hypoglycemia may develop in cases of prolonged vomiting and diarrhea. The mainstay of treatment for mild-to-moderately dehydrated patients with acute gastroenteritis should be oral rehydration solution. Antiemetics allow for improved tolerance of oral rehydration solution, and, when used appropriately, can decrease the need for intravenous fluids and hospitalization. This issue reviews the common etiologies of acute gastroenteritis, discusses more-severe conditions that should be considered in the differential diagnosis, and provides evidence-based recommendations for management of acute gastroenteritis in patients with mild-to-moderate dehydration, severe dehydration, and hypoglycemia...

REVIEW
Robert W Kenefick
In humans, thirst tends to be alleviated before complete rehydration is achieved. When sweating rates are high and ad libitum fluid consumption is not sufficient to replace sweat losses, a cumulative loss in body water results. Body mass losses of 2% or greater take time to accumulate. Dehydration of ≥  2% body mass is associated with impaired thermoregulatory function, elevated cardiovascular strain and, in many conditions (e.g., warmer, longer, more intense), impaired aerobic exercise performance. Circumstances where planned drinking is optimal include longer duration activities of >  90 min, particularly in the heat; higher-intensity exercise with high sweat rates; exercise where performance is a concern; and when carbohydrate intake of 1 g/min is desired...

Freeze-drying (FD) technique has been applied as an alternative technology to preserve gene resources to allow simple sperm preservation and shipment at 4 °C. Nevertheless, DNA sperm might be damaged by mechanical or oxidative stress throughout FD procedure. Therefore, suitable protection to maintain DNA integrity is required. The aim of this study was to determine the effect of rosmarinic acid (RA) as an antioxidant and two chelating agents (EGTA and EDTA) on the DNA integrity of freeze-dried rabbit sperm after storage of the samples at 4 °C and room temperature for 8 months...
