Enteral nutrition is preferred over parenteral nutrition as a result of the greater safety of enteral nutrition therapy and comparative convenience. A wide variety of enteral nutrition products have been developed, including disease-specific products to help manage the nutritional needs of patients with kidney failure, liver failure, lung disease, diabetes, and other conditions. An assessment of each patient's nutritional needs and digestive function should be conducted prior to initiation of enteral nutrition therapy...

The plasma derived immunoglobulin G (IgG) used either for diagnostic purpose or intravenous application (in form of IVIG) in various medical therapies is certainly gaining more and more attention on annual basis. Different manufacturing processes are used to isolate immunoglobulins from human plasma. However, a quest for alternative paths in IgG isolation not only requires development of the most efficient isolation process, but also a rapid and reliable analytics to track the purification. Fast and reliable fingerprint-based method for characterization of IgG prepared from Cohn I+II+III paste is presented in this paper...

Spectral photon counting computed tomography (SPCCT) is an emerging medical imaging technology. SPCCT scanners record the energy of incident photons, which allows specific detection of contrast agents due to measurement of their characteristic X-ray attenuation profiles. This approach is known as K-edge imaging. Nanoparticles formed from elements such as gold, bismuth or ytterbium have been reported as potential contrast agents for SPCCT imaging. Furthermore, gold nanoparticles have many applications in medicine, such as adjuvants for radiotherapy and photothermal ablation...

In this paper, we fabricate a graphene film heater through laser reduction on graphene oxide, which is a two-step process. The electrothermal performance of the graphene heater can be adjusted by the laser energy density. While the applied voltage is 18 V, the graphene heater reaches a steady-state temperature of 247.3 °C within 20 s. After the graphene heater is folded in half 100 times, its output temperature remains to be precisely controlled by the input power and the temperature distribution is uniform...

A variety of therapeutic and/or diagnostic nanoparticles (NPs), or nanomedicines, have been formulated for improved drug delivery and imaging applications. Microfluidic technology enables continuous and highly reproducible synthesis of NPs through controlled mixing processes at the micro- and nanoscale. Yet, the inherent low-throughput remains a critical roadblock, precluding the probable applications of new nanomedicines for clinical translation. Here we present robust manufacturing of lipid-polymer NPs (LPNPs) through feedback controlled operation of parallelized swirling microvortex reactors (SMRs)...

In developing countries, there are often limited resources available to provide important medical diagnostics, which severely limits our ability to diagnose conditions and administer proper treatment, leading to high mortality rates for treatable conditions. Here, we propose a multiplex tool capable of density-based cell sorting via magnetic focusing in parallel with fluorescence imaging to provide highly specific clinical assays. While many cell sorting techniques and fluorescence microscopes generally are costly and require extensive user training, limiting accessibility and usability in developing countries, this device is compact, low-cost, and portable...

Stretchable conductors can be used in various applications depending on their own characteristics. Here, we demonstrate simple and robust elastomeric conductors that are optimized for stretchable electrical signal transmission line. They can withstand strains up to 600% without any substantial change in their resistance (≤ 10% as is and ≤ 1% with passivation), and exhibit suppressed charge fluctuations in the medium. The inherent elasticity of a polymeric rubber and the high conductivity of flexible, highly oriented carbon nanotube sheets were combined synergistically, without losing both properties...

Computational protein design has advanced very rapidly over the last decade, but there remain few examples of artificial proteins with direct medical applications. This study describes a new artificial β-trefoil lectin that recognises Burkitt's lymphoma cells, and which was designed with the intention of finding a basis for novel cancer treatments or diagnostics. The new protein, called "Mitsuba", is based on the structure of the natural shellfish lectin MytiLec-1, a member of a small lectin family that uses unique sequence motifs to bind α-D-galactose...

The wax sculpting of a maxillofacial prosthesis is challenging, time-consuming, and requires great skill. Rapid prototyping (RP) systems allow these hurdles to be overcome by enabling the creation of a customized 3D model of the desired prosthesis. Geomagic and Mimics are the most suitable software programs with which to design such prostheses. However, due to the high cost of these applications and the special training required to operate them, they are not widely used. Additionally, ill-fitting margins and other discrepancies in the final finished products of RP systems are also inevitable...
