Combinatorial Multidomain Mesoporous Chips for Fractionation of Biomolecules

The chips can operate with extraordinary rapidity without sample pre-processing. Lyndon B. Johnson Space Center, Houston, Texas A promising strategy of early diagnosis is the detection of biological signatures (molecular biomarkers) from readily available body fluids, such as blood. However, the onset of most human diseases cannot be univocally identified on the basis of a single biomarker. Considerable attention has been devoted to the development of proteomic methods for the quantitative and simultaneous detection and identification of “signature profiles” constituted by multiple protein and peptide biomarkers using mass spectrometry (MS). A critical aspect of the development of MS-based proteomics and peptidomics is the extraordinarily broad assortment of molecular species in blood, with concentrations ranging over more than ten orders of magnitude. This dynamic complexity limits the detection of disease-related peptides present in trace amounts within a large background of very abundant and non-relevant proteins.

Rapid PCR Instrument Development

Today, there is great demand for next-generation polymerase chain reaction (PCR)-based diagnostics for the rapid analysis of patient samples and simultaneous detection of multiple diverse markers. Generally, PCR imaging systems limit testing to one, slow PCR protocol at a time. To complete multiple independent tests requires multiple runs over several hours or even days. The solution is a new, rapid, real-time PCR instrument with multiple, randomly accessible thermal blocks and easy-to-use software that provides researchers and clinicians with flexibility in workflow with rapid results in 20 minutes.

Parallel Prototyping and the Engineer’s Dilemma

R&D Engineers face rapidly shrinking development cycles and rising competitive pressures. In the high-stakes practice of regulatory compliance, balancing development costs with speed, safety and performance are critical to a product’s success. This paper demonstrates how the parallel prototyping of two materials in a heating component contributes to the return on investment of a new product launch in the medical device industry. The study addresses the verification, validation, form and fit testing relative to the FDA approval process, as well as its execution within component design, product design and pilot production.

Molds for Medical Technology

The demand for productivity in the field of medical consumables is consistently growing at a rapid rate. The growth of the world’s population, expanding urbanization, aging societies, and increasing self-medication are contributing to this growing demand, despite manufacturers’ limited production space. Costs continue to rise, and manufacturers are increasingly looking at stack molds for their capability to double the output while reducing waste.

The Truth about Parylene Coating & Medical Devices

Parylene is the generic name for members of a unique polymer series. Parylene conformal coatings represent a distinct family of organic polymeric coating materials that are polycrystalline and linear in nature, with innumerable commercial applications. Resilient, dielectric, and pinhole-free, parylenes are frequently selected for use with products subjected to ongoing conditions of duress that might otherwise diminish their performance.

Intranasal Scopolamine — INSCOP

This drug, in intranasal form, is an effective treatment for motion sickness. Lyndon B. Johnson Space Center, Houston, Texas Space motion sickness (SMS) commonly experienced by astronauts during a space mission often requires treatment with medication. However, exposure to a microgravity environment results in a myriad of physiological changes that alter bioavailability. In particular, studies indicate that the bioavailability of oral scopolamine (SCOP) is decreased during spaceflight. Although altered gastrointestinal function, including delayed gastric emptying, appears to contribute to decreased bioavailability of oral medications, other factors typical of spaceflight may influence the pharmacokinetics of medications administered via a variety of other non-parenteral routes.
