To increase farm income and food security, a collaboration was made with smallholder women farmers in Kaffrine, Senegal to develop a culturally acceptable peanut nutrition bar using healthy indigenous and local ingredients and feasible manufacturing methods. This study aimed to use response surface methodology to optimize the bar's formulation and characterize the texture, nutrient profile, sensory qualities, and water activity. The bars were made by varying the ratio of cowpea flour to corn flour (w/w, d.

Recent Findings: A retrospective single-center review of N = 17 consecutive patients who underwent pelvic MRI for the assessment of PVI was performed. N = 8/17 (47%) studies were positive for PVI.
Decontaminating civilian facilities or large urban areas following an attack with Bacillus anthracis poses daunting challenges because of the lack of resources and proven technologies. Nevertheless, lessons learned from the 2001 cleanups together with advances derived from recent research have improved our understanding of what is required for effective decontamination. This article reviews current decontamination technologies appropriate for use in outdoor environments, on material surfaces, within large enclosed spaces, in water, and on waste contaminated with aerosolized B.

Such studies are further complicated due to the demanding computational resources required to implement high-level ab initio quantum chemical methods when considering the solvent explicitly. Here, we use first-principles molecular dynamics simulations to examine condensed-phase decontamination reactions of V-type nerve agents in an explicit aqueous solvent.

Consequence management following a release of aerosolized Bacillus anthracis spores requires a high level of technical understanding and direction. National policies and regulations address the topics of preparedness goals and organizational structure, but they do not tell responders how to perform remediation. Essential considerations include determining what must be cleaned, evaluating health risks, ascertaining the priority of cleanup, and selecting appropriate decontamination technologies to meet consensus and risk-derived clearance goals.

Recovering from a biological attack is a complex process requiring the successful resolution of numerous challenges. The Interagency Biological Restoration Demonstration program is one of the first multiagency efforts to develop strategies and tools that could be effective following a wide-area release of B. anthracis spores.

Current biological agent identification and viability determination methods are both labor- and time-intensive such that turnaround time for confirmed results is typically several days. In order to alleviate this issue, automated, high-throughput sample processing methods were developed in which real-time PCR analysis is conducted on samples before and after incubation.

While timeframes are dependent on numerous variables, a primary controlling factor is the level of pre-planning and decision-making completed prior to chemical release. What follows is the second of a two-part analysis identifying key considerations, critical information and decision criteria to facilitate post-attack and post-decontamination consequence management activities.

Current methods to confirm the presence of a viable biothreat agent are limited by low sample throughput. We have developed a rapid-viability-polymerase chain reaction (RV-PCR) method to determine the presence of viable spores.

Although capillary chambers are straightforward and economical to construct, the curved capillary wall introduces image aberrations. The significance of these aberrations in imaging sub-cellular-dimension objects has yet to be assessed.

Purpose: To determine if nonenhancing tissue on gadolinium-enhanced magnetic resonance (MR) images obtained 3 weeks after cryoablation of the prostate helps reliably and accurately predict nonviable cryoablated tissue at 6-month biopsy.
Materials And Methods: Fifty-four consecutive patients with prostate cancer who underwent cryoablation were followed up prospectively. Fifty-one underwent gadolinium-enhanced MR imaging at 3 weeks (three had gadolinium allergy); 49, biopsy at 6 months (three refused and two had other primary malignancies); and all, prostate-specific antigen (PSA) tests at 6 weeks, 3 months, and every 3 months thereafter.
Recent terrorist events underscore the urgent need to develop a comprehensive set of health-protective cleanup standards and effective decontamination technologies for use in the restoration of civilian facilities. Accurate scientific information remains limited in the area of biological warfare agents. However, new guidelines and calculated cleanup values are emerging for initial re-entry and long-term reoccupation following use of chemical warfare agents.
