Advancing medical technology continues to extend the average human life span, resulting in population aging globally as well as in Taiwan. The challenges posed by aging society increase not only medical and care costs but also the burden on pension funds and the social welfare system. In addition, there is currently a desperate need for many well-trained health providers as well as a friendly and comprehensive long-term care system. However, attention should not simply focus on medical payments and long-term care, as this may prolong the length of unhealthy living years for the aged and further strain national finances...

Nano packaging is currently one of the most important topics in food packaging technologies. The aim of the application of this technology in food packaging is increasing shelf life of foods by preventing internal and external corruption and microbial contaminations. Use of silver nanoparticles in food packaging has recently attracted much attention. The aim of this study was to investigate the effect of nano-silver packaging in increasing the shelf life packages of nuts in an In vitro model. In this experimental study, the effects of different nano-silver concentrations (0, 1, 2 and 3 percent) on biological and chemical properties of 432 samples of nuts including walnuts, hazelnuts, almonds and pistachios were evaluated during 0, 3, 6, 9, 12, 15, 18, 21 and 24 months...

Sialolithiasis is one of the most common and extensively obstructive disorders of the major salivary glands. Here, we report 3 cases of sialolithiasis in the submandibular salivary gland showing symptomatic similarities to other dental and non-dental disorders of the maxillofacial area. How the various clinical features of this condition and findings on 3D-CT may lead to a misdiagnosis are also discussed. In the first case, that of a 45-year-old woman, a final diagnosis of a non-radiopaque submandibular sialolith allowed the initially indicated surgical extraction of a malerupted and semi-impacted right mandibular 3rd molar to be abandoned...

The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein-9 nuclease (Cas9) is a genome editing tool that has recently caught enormous attention due to its novelty, feasibility, and affordability. This system naturally functions as a defense mechanism in bacteria and has been repurposed as an RNA-guided DNA editing tool. Unlike zinc-finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs), CRISPR/Cas9 takes advantage of an RNA-guided DNA endonuclease enzyme, Cas9, which is able to generate double-strand breaks (DSBs) at specific genomic locations...

Hypertension is a complex, multifactorial disease that involves the coexistence of multiple risk factors, environmental factors and physiological systems. The complexities extend to the treatment and management of hypertension, which are still the pursuit of many researchers. In the last two decades, various genes have emerged as possible biomarkers and have become the target for investigations of specialized drug design based on its risk factors and the primary cause. Owing to the growing technology of microarrays and next-generation sequencing, the non-protein-coding RNAs (ncRNAs) have increasingly gained attention, and their status of redundancy has flipped to importance in normal cellular processes, as well as in disease progression...

Uranyl peroxide clusters containing from 16 to 124 uranyl ions self-assemble in aqueous solution and exhibit tremendous topological complexity. Most of these clusters are cages, with the inside and outside surfaces passivated by oxygen atoms that are triply bonded to U(vi) cations (yl oxygen). It has become increasing apparent that the counter cations associated with these anionic cage clusters impact their assembly, topologies, and behavior in solution, including aggregation and aqueous solubility. Here we review the chemical compositions and topologies of uranyl peroxide clusters...

The concept of Cancer Stem Cells (CSCs) and the CSC Niche/Tumor Microenvironment (TME) as the central driving force behind tumor progression and maintenance has garnered much attention in recent years. Concomitantly, the widespread adoption of 3D tissue models, organotypic co-cultures, and the revolutionary microfluidic technology has resulted in a plethora of ground-breaking fundamental discoveries and has enabled investigations which were previously unfeasible. A large number of existing review papers concern themselves with either a broad look at the TME and CSC Niche, or on the studies undertaken on a particular niche component alone...

The lung microbiota has received less attention compared to other body sites, in part because its study carries special technological difficulties related to obtaining reliable samples as compared to other body niches. The limited number of studies on the sputum microbiota on TB patients and controls available so far have reported inconsistent, and sometimes, contradictory results. Aiming to clarify if changes in the lung microbiota composition are associated with pulmonary TB, we performed a meta-analysis of available data on microbiota of the lower respiratory tract in TB patients and healthy controls...

Cell therapies offer unquestionable promises for the treatment, and in some cases even the cure, of complex diseases. As we start to see more of these therapies gaining market authorization, attention is turning to the bioprocesses used for their manufacture, in particular the challenge of gaining higher levels of process control to help regulate cell behavior, manage process variability, and deliver product of a consistent quality. Many processes already incorporate the measurement of key markers such as nutrient consumption, metabolite production, and cell concentration, but these are often performed off-line and only at set time points in the process...

Listeners with sensorineural hearing loss often have trouble understanding speech amid other voices. While poor spatial hearing is often implicated, direct evidence is weak; moreover, studies suggest that reduced audibility and degraded spectrotemporal coding may explain such problems. We hypothesized that poor spatial acuity leads to difficulty deploying selective attention, which normally filters out distracting sounds. In listeners with normal hearing, selective attention causes changes in the neural responses evoked by competing sounds, which can be used to quantify the effectiveness of attentional control...

Other than a few avascular tissues, almost all human tissues are connected to the systemic circulation via blood vessels that promote metabolism and function. Accordingly, engineered vascularization is a vital goal in tissue engineering for regenerative medicine. Endothelial cells (ECs) play a central role in vascularization with two significant specificities: physical interfaces between vascular stroma and blood, and phenotypic organ-specificity. Biomaterial scaffolding technologies that address these unique properties of ECs have been developed to promote the vascularization of various engineered tissues, and these have advanced from mimicking vascular architectures ex situ towards promoting spontaneous angiogenic remodeling in situ...

Industrial synthesis of enantiopure compounds is nowadays heavily based on the separation of racemates through crystallization processes. Although the application of ultrasound in solution crystallization processes (sonocrystallization) has become a promising emerging technology, offering several benefits (e.g. reduction of the induction time and narrowing of the metastable zone width, control over the product size, shape and polymorphic modification), little attention has been paid so far to the effects of ultrasound on chiral crystallization processes...

While attention on the importance of closing materials loops for achieving circular economy (CE) is raging, the technicalities of doing so are often neglected or difficult to overcome. However, these technicalities determine the ability of materials to be properly recovered and redistributed for reuse or recycling, given the material, component and product (MCP) state and functionality. Materials have different properties that make them useful for various functions and purposes. A transition, therefore, towards a CE would require the utmost exploitation of all available routes that MCPs can be diverted to, based on their design, use and recovery; ideally, enabling a perpetual looping of them in the economy...

Mixtures of ionic liquids (ILs) have attracted our attention because of their extraordinary performances in extraction technologies and in absorbing large amount of CO2 gas. It has been observed that when two or more ILs are mixed in different proportions, a new solvent is obtained which is much better than that of each component of ILs from which the mixture is obtained. Within a mixture of ILs, several unidentified interactions occur among several ions which give rise to unique solvent properties to the mixture...

As an efficient method for ammonium (NH4 + ) removal, contact catalytic oxidation technology has drawn much attention recently, due to its good low temperature resistance and short start-up period. Two identical filters were employed to compare the process for ammonium removal during the start-up period for ammonium removal in groundwater (Filter-N) and surface water (Filter-S) treatment. Two types of source water (groundwater and surface water) were used as the feed waters for the filtration trials. Although the same initiating method was used, Filter-N exhibited much better ammonium removal performance than Filter-S...

Many forms of victimization, including bullying and property crime, are increasingly moving online, but most studies of poly-victimization still primarily focus on in-person crime and violence. Few studies have examined the importance of incorporating technology-based victimizations for assessing the true burden of violence. The purpose of this study is to explore whether digital poly-victimization contributes to post-traumatic stress and anxiety/dysphoria symptoms after controlling for in-person poly-victimization...
