Immiscible fluid systems are ubiquitous in industry, medicine and nature. Understanding the phase morphologies and intraphase fluid motion is often desirable in many of these situations; for example, this will aid improved design of microfluidic platforms for the production of medicinal formulations. In this paper, we detail a Smoothed Particle Hydrodynamics (SPH) approach that facilitates this understanding. The approach includes surface tension and enforces incompressibility. The approach also allows the consideration of an arbitrary number of immiscible phases of differing viscosities and densities...

Artificial membranes mimicking biological structures are rapidly breaking new ground in the areas of medicine and soft-matter physics. In this endeavor, we use dissipative particle dynamic (DPD) simulation to investigate the morphology and behavior of lipid-based biomembranes under conditions of varied lipid density and self-interaction. Our results show that a less-than-normal initial lipid density does not create the traditional membrane; but instead results in the formation of a 'net', or at very low densities, a series of disparate 'clumps' similar to the micelles formed by lipids in nature...

The development of personalized medicine in oncology is based on biomarkers that help select populations for more efficient and less toxic therapies. The onset of molecular biology led to new paradigms in drug development, with efficacy data reported in early clinical trials and accelerated approvals. Multiple clinical trials, including SHIVA, SAFIR-01 and MOSCATO-01, have been developed to evaluate the interest of treatment decision-making based on tumor molecular profiling, with the ambition to replace historical clinical and pathological classifications...

A frequent quandary for oncologists is the selection of chemotherapy and biologic therapy for patients with metastatic colorectal cancer in second-line and higher treatment settings. While not approved by the US Food and Drug Administration (FDA) in the first-line setting, the vascular endothelial growth factor (VEGF)-targeting agents ziv-aflibercept and ramucirumab are appropriate treatment options in the second-line setting, as is continuation of first-line bevacizumab. Tumor RAS mutational status is helpful to determine which patients may benefit from epidermal growth factor receptor (EGFR)-directed therapies, and other novel biomarkers (BRAF, HER2, and mismatch repair deficiency) allow us to select patients who may benefit from biologic therapies that are FDA-approved for other malignancies...

DNA damage occurs continually through various intrinsic and extrinsic mechanisms such as ultraviolet radiation, smoking, reactive oxygen species, and errors during replication. The cellular DNA damage response (DDR) comprises signaling networks that regulate a spectrum of processes, including cell cycle progression, which enable DNA repair to occur. Ataxia telangiectasia mutated (ATM) and ataxia telangiectasia mutated and rad3-related (ATR) kinase are 2 key regulators of the DDR cell cycle checkpoints. ATR plays an essential role in the repair of replication-associated DNA damage, while ATM is activated by DNA double-strand breaks...

In the latter part of the 20th century, drug development in cardiovascular diseases (CVDs) was a paragon of "modern" therapeutics, bringing about a substantial number of effective, well-tolerated agents targeting some of the most prevalent diseases of the Western world. These drugs were often examples of rational drug development targeting specific pathophysiologic pathways previously elucidated through basic research (e.g., targeting of the renin-angiotensin system or the cholesterol synthesis pathway). The widespread adoption of these ground-breaking medications in practice and into medical guidelines undoubtedly played a role in the fall of morbidity and mortality from CVD in the United States in recent decades...

The present Addendum complements the accompanying paper "Cellular Gauge Symmetry and the Li Organization Principle"; it illustrates a recently-developed geometrical physical model able to assess electronic movements and energetic paths in atomic shells. The model describes a multi-level system of circular, wavy and zigzag paths which can be projected onto a horizontal tape. This model ushers in a visual interpretation of the distribution of atomic electrons' energy levels and the corresponding quantum numbers through rather simple tools, such as compasses, rulers and straightforward calculations...

Despite decades of research, visions of transforming neuropsychiatry through the development of brain imaging-based "growth charts" or "lab tests" have remained out of reach. In recent years, there is renewed enthusiasm about the prospect of achieving clinically useful tools capable of aiding the diagnosis and management of neuropsychiatric disorders. The present work explores the basis for this enthusiasm. We assert that there is no single advance that currently has the potential to drive the field of clinical brain imaging forward...

Molecular medicine has entered a high-tech age that provides curative treatments of complex genetic diseases through genetically engineered cellular medicinal products. Their clinical implementation requires the ability to stably integrate genetic information through gene transfer vectors in a safe, effective and economically viable manner. The latest generation of Sleeping Beauty (SB) transposon vectors fulfills these requirements, and may overcome limitations associated with viral gene transfer vectors and transient non-viral gene delivery approaches that are prevalent in ongoing pre-clinical and translational research...

One of the major challenges to the cell is to ensure genome stability, which can be compromised through endogenous errors or exogenous DNA damaging agents, such as ionizing radiation or common chemotherapeutic agents. To maintain genome stability the cell has a multifaceted line of defense, including cell cycle checkpoints and DNA damage repair pathways. RAD54B is involved in many of these pathways and thus exhibits a role in maintaining and repairing genome stability following DNA damage. RAD54B is involved in cell cycle regulation after DNA damage and participates in homologous recombinational repair, which ensures the precise repair of the most deleterious DNA lesions, double-stranded breaks...

Ayurveda is a holistic medical system of traditional medicine, and Triphala is one of the most popular formulations in Ayurveda. Triphala is composed of three kinds of herb, Terminalia chebula, Terminalia bellirica, and Emblica officinalis. Since Triphala is shown to exhibit a protective activity against ionizing radiation in mice, we investigated its activity in HeLa cells. We found that Triphala showed the protective effects against X-radiation and bleomycin, both of which generate DNA strand breaks, in HeLa cells...

Cancer is the leading cause of death worldwide. Although cancer occurs as a localized disease, its morbidity and mortality rates remain high due to the ability of cancer cells to break-off from the primary tumor and spread to distant organs. Currently, chemotherapy is the main treatment for cancer; however, the increase in proportion of drug-resistant cancer cells and unpleasant side-effects of chemotherapy are still the major challenges in cancer therapy. Curcumin is a natural polyphenol compound and the main bioactive constituent of Indian spice turmeric, widely used in Indian and Chinese medicines...

Therapy with current antiepileptic drugs aims at reducing the likelihood of seizure occurrence rather than influencing the underlying disease process. Therefore, antiepileptic drugs have an anticonvulsant rather than antiepileptic property. Areas covered: The increasing identification of genetic causes for epilepsy over the recent years improves the understanding of the underlying epileptogenic process and allows for the possibility of directed therapeutic approaches. An ideal antiepileptic therapy consists of a drug which is able to influence the functional changes caused by a specific pathogenic variant...

Stripped of any sense of comfort or dignity on that hospital bed, my 84-year-old father, my best friend, was enduring raw, intrusive medical procedures against his own wish; defenseless, vulnerable, agonized. A feeding tube went in through his nose; catheter tubes drained urine out of his bladder; a suction pump drew out fluid from his airway. A needle jammed into the central line, making it impossible for him to turn his head. Dialysis took over the job of his kidneys. But no painkillers were given for fear his weak heart could not take more chemicals...

The Malayan box turtle (Cuora amboinensis) (MBT) is a vulnerable and protected species widely used in exotic foods and traditional medicines. Currently available polymerase chain reaction (PCR) assays to identify MBT lack automation and involve long targets which break down in processed or denatured tissue. This SYBR Green duplex real-time PCR assay has addressed this research gap for the first time through the combination of 120- and 141-bp targets from MBT and eukaryotes for the quantitative detection of MBT DNA in food chain and herbal medicinal preparations...
