5-Keto-D-Fructose, a Natural Diketone and Potential Sugar Substitute, Significantly Reduces the Viability of Prokaryotic and Eukaryotic Cells.

5-Keto-D-fructose (5-KF) is a natural diketone occurring in micromolar concentrations in honey, white wine, and vinegar. The oxidation of D-fructose to 5-KF is catalyzed by the membrane-bound fructose dehydrogenase complex found in several acetic acid bacteria. Since 5-KF has a sweetening power comparable to fructose and is presumably calorie-free, there is great interest in making the diketone commercially available as a new sugar substitute.

Doxorubicin-Loaded Human Serum Albumin Submicron Particles: Preparation, Characterization and In Vitro Cellular Uptake.

Doxorubicin (DOX) is an effective anthracycline antibiotic drug which is commonly used in a broad range cancer therapy. However, due to dose depending side effects and toxicity to non-cancerous tissues, its clinical applications are restricted. To overcome these limitations, human serum albumin (HSA) has been investigated as a biocompatible drug delivery vehicle.

The Tumor Microenvironment as a Regulator of Endocrine Resistance in Breast Cancer.

Estrogen receptor positive breast neoplasias represent over 70% of diagnosed breast cancers. Depending on the stage at which the tumor is detected, HER2 status and genomic risk, endocrine therapy is combined with either radio, chemo and/or targeted therapy. A growing amount of evidence supports the notion that components of the tumor microenvironment play specific roles in response to treatment and that strategies targeting these key interactions with tumor cells could pave the way to a new generation of therapies.

The medical value and cost-effectiveness of an exercise test for sport preparticipation evaluation in asymptomatic middle-aged white male and female athletes.

Background: Cardiovascular events related to high-intensity sport practice are rare but dramatic. Coronary artery disease (CAD) is the leading cause of these events after the age of 35 years. The value of a maximal exercise test (ET) for detection of athletes at risk remains a matter of debate.

Wraparound Team Composition, Youth Self-determination, and Youth Satisfaction in Transition Services.

Wraparound, a team-based planning process for youth and families, has been widely adopted in school-based services for older adolescents and emerging adults with serious mental health conditions transitioning to adulthood. Reservations have been voiced, however, regarding possible drawbacks of teams for these youth, including concerns about difficulties with involving supportive adults, and whether youth might perceive team-based planning as a threat to their developing autonomy. To date, however, no studies have examined the feasibility of involving supports in teams and relationships between team composition and youth's service experiences.
