Zeptomole Detection of C-Reactive Protein in Serum by a Nanoparticle Amplified Surface Plasmon Resonance Imaging Aptasensor

Abstract: Diagnostic biomarkers (i.e. proteins) are often in low abundance in bodily fluids presenting many challenges for their detection. In order to extend the application of SPRi systems in detecting biomarkers at ultralow levels, we combine the advantage of aptamer technology with nanomaterials and microwave-assisted surface functionalization. By implementing a sandwich assay through the introduction of aptamer-modified quantum dots (QDs), it was possible to measure 7 zeptomole (at 5 fg/mL) of C-reactive protein (CRP) selectively in spiked human serum. It is expected that the proposed platform will provide new direction in designing ultrasensitive SPRi biosensors with multiplexing capabilities.

A diet containing food rich in soluble and insoluble fiber improves glycemic control and reduces hyperlipidemia among patients with type 2 diabetes mellitus.

Abstract: The clinical significance of fiber on metabolic control among people with type 2 diabetes is debatable. Patients with type 2 diabetes who consumed a diet containing food naturally rich in fiber (e.g., 50 g fiber/day, 50% soluble) for 6 weeks had significant improvements in glycemic control and lipid panels when compared with patients who consumed a diet with moderate amounts of fiber (e.g., 25 g fiber/day, 50% soluble). Whether this high intake of fiber-rich food, especially fruits, can be maintained, tolerated without side effects or micronutrient deficiencies, and affordable for longer than 6 weeks in people with type 2 diabetes remains to be determined.

First-Time Suicide Attempters, Repeat Attempters, and Previous Attempters on an Adolescent Inpatient Psychiatry Unit

Abstract: Objective To compare clinical characteristics of hospitalized adolescents who (1) have recently made their first suicide attempt, (2) have recently made a second or subsequent attempt, (3) have made previous but no recent attempts, or (4) have never made an attempt. Method Semistructured psychiatric diagnostic interviews were used to determine history of recent and previous suicidal behavior among 225 consecutively admitted adolescents to an inpatient psychiatric facility. Twenty-seven first-time attempters, 32 repeat attempters, and 40 previously suicidal youths were compared with 126 nonsuicidal youths in terms of severity of self-reported depressive symptoms, state anxiety, trait anxiety, state anger, and trait anger. Results Repeat attempters and previous attempters both reported more depressive symptomatology and trait anxiety than did nonsuicidal youths. In addition, youths with a previous history of suicide attempts, but no recent attempts, evidenced more trait anger than all other groups. First-time suicide attempters reported levels of distress that were intermediate to the other groups. Conclusions Repeat attempters and previous attempters in hospital settings both report more distress than do nonsuicidal youths. Interventions should focus not only on resolution of immediate crises, but also on youths' ability to cope with ongoing difficulties that engender depression and chronic anxiety.
