Approximately 40 % drugs in the market are having poor aqueous solubility related problems and 70 % molecules in discovery pipeline are being practically insoluble in water. Nanocrystals is a prominent tool to solve the issue related to poor aqueous solubility and helps in improving the bioavailability of many drugs as reported in literature. Nanocrystals can be prepared by top down methods, bottom up methods and combination methods. Many patented products such as Nanocrystals®, DissoCubes®, NANOEDGE® and SmartCrystals®, etc...

BACKGROUND: Cancer is a major cause death in the worldwide. The etiology of cancer is linked environmental and genetic inheritance causes. Approximately 90 percent of all human cancers have an environmental cause (non-genetic inheritance) predominantly through lifestyle choices (smoking, diet, UV radiation) with the remainder infections and chemical exposure. Cancer is a multistage process that involves mutational changes and uncontrolled cell proliferation. Research has firmly established a causal and contributory role of oxidative stress and oxidative damage in cancer initiation and progression...

The role of endovascular interventions has progressed rapidly over the past several decades. While animal models have long served as the mainstay for the advancement of this field, the use of in vitro models has become increasingly widely adopted with recent advances in engineering technologies. Here we review the strategies, mainly including bioprinting and microfabrication, that allow for fabrication of biomimetic vascular models that will potentially serve to supplement the conventional animal models for convenient investigations of endovascular interventions...

Drug efficacy and toxicity are key factors of drug development. Conventional 2D cell models or animal models have their limitations for the efficacy or toxicity assessment in preclinical assays, which induce the failure of candidate drugs or withdrawal of approved drugs. Human organs-on-chips (OOCs) emerged to present human-specific properties based on their 3D bioinspired structures and functions in the recent decade. In this review, basic definition and superiority of OOCs will be introduced. Moreover, a specific OOC, heart-on-a-chip (HOC) will be focused...

For the last decades, bioengineers have developed myriad biomaterials for the regenerative medicine. Developments of screening techniques is essential in understanding complex behavior of cells in the biological microenvironments. Conventional approaches to screening of cellular behavior in vitro have limitations in terms of accuracy, reusability, labor-intensive screening, and versatility. Thus, drug screening and toxicology test through in vitro screening platforms have been underwhelming. Recent advances in the high-throughput screening platforms somewhat overcomes the limitations of in vitro screening platforms via repopulating human tissues' biophysical and biomchemical microenvironments with the ability to continual monitoring of miniaturized human tissue behavior...

The skin is the largest and most exposed organ in the human body. Not only it is involved in numerous biological processes essential for life but also it represents a significant end point for the application of pharmaceuticals. The area of in vitro skin tissue engineering has been progressing extensively in the recent years. Advanced in vitro human skin models strongly impact the discovery of new drugs thanks to the enhanced screening efficiency and reliability. Nowadays, animal models are largely employed at the preclinical stage of new pharmaceutical compounds development for both risk assessment evaluation and pharmacokinetic studies...

The oncology pharmaceutical research spent a shocking amount of money on target validation and drug optimization in preclinical models because many oncology drugs fail during clinical trial III. One of the most important reason of oncology drug failures in clinical trials may due to the poor predictive tool of existing preclinical models. Therefore, in cancer research and personalized medicine field, it is critical to improve the effectiveness of preclinical predictions of the drug response of patients to therapies and to reduce costly failures in clinical trials...

Despite the fact that protein and peptide therapeutics are widely employed in the treatment of various diseases, their delivery is posing an unembellished challenge to the scientists. It was discovered that delivery of these therapeutic systems through oral route is easy with high patient compliance. However, proteolytic degradation and absorption through the mucosal epithelium are the barriers in this route. These issues can be minimized by the use of enzyme inhibitors, absorption enhancers, different carrier systems or either by direct modification...

BACKGROUND: Among polyphenolic compounds suggested to prevent cardiovascular diseases (CVDs) and to explain the "French paradox", the anthocyanidin delphinidin (Dp) has been reported to support at least partly the vascular beneficial effects of dietary polyphenolic compounds including those from fruits and related products as red wine. It has also been highlighted that Dp interacts directly with the active site of estrogen receptor α (ERα), leading to an activation of endothelial NO synthase (eNOS) pathway thus contributing to the prevention of endothelial dysfunction in mice aorta...

BACKGROUND: Ulinastatin (UTI) plays the beneficial roles in modifying cerebral ischemic injury evoked by cardiac arrest (CA). XueBiJing (XBJ), comprised of extracts from Chinese herbals, has been used for the treatment of sepsis and ischemic disorders linked to multiple organ dysfunction syndromes. The current study was to find interventions that can enhance effectiveness of these drugs and further to provide a fundamental for their rational application in clinical practice. Thus, we examined how apoptosis signal in the hippocampus is engaged in a facilitating role of UTI and XBJ in improving neural injury and neurological functions after transient cerebral ischemia...

BACKGROUND: Testosterone insufficiency may play a role in age-related decreases in bone mass density (BMD) and osteoporosis in aging men. Testosterone replacement therapy (T therapy) seems to be a simple and convenient way to increase BMD and improve the condition of osteoporosis. OBJECTIVE: To evaluate the effects of T therapy in increasing BMD among older men with low serum testosterone concentrations. METHODS: A comprehensive search in the PubMed, EMBASE, Web of Science and Cochrane Central databases was undertaken for randomized controlled trials (RCTs) on the effect of T therapy on osteoporosis in aging men...

BACKGROUND: Pseudophakic cystoid macular edema (PCME) remains one of the most common vision threatening complications of phacoemulsification cataract surgery (PCS). Pharmacological therapy is the current mainstay of both prophylaxis, and treatment of patients undergoing PCS. We aimed to review of pharmacological treatment options for PCME, which primarily includes topical steroids, topical nonsteroidal anti-inflammatory drugs (NSAIDS), periocular and intravitreal steroids, as well as anti-vascular endothelial growth factor therapy...

BACKGROUND: Choroidal neovascularization (CNV) in adults is most commonly associated with neovascular age-related macular degeneration (AMD) and pathologic myopia. Though less common, CNV can also develop from other conditions such as uveitis, central serous chorioretinopathy, angioid streaks, intraocular tumors, hereditary chorioretinal dystrophies, or can be idiopathic in origin. If left untreated, CNV may cause visual loss because of exudation of intraretinal or subretinal fluid, retinal or subretinal hemorrhage, or fibrosis involving the macula...
