Fracture-based micro- and nanofabrication for biological applications.

While fracture is generally considered to be undesirable in various manufacturing processes, delicate control of fracture can be successfully implemented to generate structures at micro/nano length scales. Fracture-based fabrication techniques can serve as a template-free manufacturing method, and enables highly-ordered patterns or fluidic channels to be formed over large areas in a simple and cost-effective manner. Such technologies can be leveraged to address biologically-relevant problems, such as in the...

Genetic architecture of human fibrotic diseases: disease risk and disease progression.

Genetic studies of human diseases have identified multiple genetic risk loci for various fibrotic diseases. This has provided insights into the myriad of biological pathways potentially involved in disease pathogenesis. These discoveries suggest that alterations in immune responses, barrier function, metabolism and telomerase activity may be implicated in the genetic risks for fibrotic diseases. In addition to genetic disease-risks, the identification of genetic disease-modifiers associated with disease com...

Mechanical versus biological heart valves.

Since the first successful heart valve replacement procedures were performed in the 1950s, a multitude of different heart valves have been developed and implanted. This review offers a structured overview of the most important mechanical and biological heart valves with special regard to the individual indications of mechanical versus biological heart valve replacement and to possible postoperative complications.

Surface Markers of Cancer Stem Cells in Solid Tumors.

Cancer stem cells (CSCs) are a small subpopulation of cells within tumors with capabilities of self-renew, differentiation, and tumorigenicity. Successful cancer treatment would need to eliminate CSCs. The CSCs can be identified and isolated by both CSC-specific cell surface marker expression and functional assay, such as floating spheres, and aldehyde dehydrogenase (ALDH) activity assay. However, lack of universal expression of surface markers limits their usage to identify CSCs. Here, we give a brief over...

An Overview of Optimal Endovascular Strategy in Treating the Femoropopliteal Artery: Mechanical, Biological, and Procedural Factors.

Treatment of the femoropopliteal (FP) artery remains a challenge to the endovascular specialist. Long-term patency is low with a high rate of target lesion revascularization. The true patency rate varies considerably between studies partly because there is a lack of uniform performance criteria and reporting standards in peripheral arterial interventions. Literature review supports three principles that emerge as important components of an optimal strategy in treating the FP artery: (1) improving vessel com...

An overview of current Italian studies on bacterial pathogenesis.

Effects of Marketed Antiepileptic Drugs and Placebo in the Human Photosensitivity Screening Protocol.

A study of epilepsy patients with a reproducible range of photoparoxysmal responses (PPR) (epileptiform discharges evoked by flashing lights) has been used as a "proof-of-concept" trial to determine if novel potential antiepileptic drugs (AEDs) should proceed in development. The standard design for this trial requires a 3-day inpatient stay and is single-blind. We evaluated two marketed and effective AEDs-one narrow-spectrum [carbamazepine (CBZ)], and one broad-spectrum [levetiracetam (LEV)]-using a novel d...

The role of peer relationships in parental bereavement during childhood and adolescence.

This article reviews current knowledge concerning the relationship between peer support and adjustment outcomes and experiences for parentally bereaved children. A brief overview of the effects of parental bereavement and factors influencing immediate and long-term adjustment is provided, followed by an overview of peer-provided social support and its relationship to adjustment. Current findings on the predictive value of peer support for adjustment are then discussed, with emphasis on the reciprocal positi...

Small proteins: untapped area of potential biological importance.

Polypeptides containing ≤100 amino acid residues (AAs) are generally considered to be small proteins (SPs). Many studies have shown that some SPs are involved in important biological processes, including cell signaling, metabolism, and growth. SP generally has a simple domain and has an advantage to be used as model system to overcome folding speed limits in protein folding simulation and drug design. But SPs were once thought to be trivial molecules in biological processes compared to large proteins. Bec...

Idiopathic inflammatory myopathies are systemic, immune-mediated diseases characterized by proximal, symmetrical, progressive muscle weakness. The aim of this work is to give an overview of the biological therapy used in the treatment of idiopathic inflammatory myopathies. The authors also focus on novel results in the therapy directed against the B- and T-cells. They emphasize the importance of new trials in these diseases which may lead to the introduction of novel therapeutic options in these disorders....

Centella asiatica in Dermatology: An Overview.

Centella asiatica is a medicinal plant that was already used as a 'panacea' 3000 years ago. The active compounds include pentacyclic triterpenes, mainly asiaticoside, madecasosside, asiatic acid and madecassic acid. We have conducted an overview to summarize current knowledge on the results of scientific in vitro and in vivo experiments focused on the improvement of the healing process of small wounds, hypertrophic scars and burns by C. asiatica. In this paper, we discuss the data on constituents, recommend...

Finally, to make this review useful...

Methadone, QTc prolongation and torsades de pointes: Current concepts, management and a hidden twist in the tale?

Methadone is a drug that has found widespread utility in the management of opioid addiction and pain. Along with its popularity, methadone has also earned an infamous reputation for causing prolongation of the QT interval and an increased risk of torsades de pointes. In this article we will give a brief overview of the long QT syndromes, followed by an in-depth look at the current pathophysiologic mechanisms of methadone induced QT prolongation, a review of the existing literature and the current concepts r...

Ocular Anti-VEGF Therapy for Diabetic Retinopathy: The Role of VEGF in the Pathogenesis of Diabetic Retinopathy.

Diabetic retinopathy is the leading cause of visual impairment and preventable blindness, and represents a significant socioeconomic cost for health care systems worldwide. Therefore, new approaches beyond current standards of diabetes care are needed. Based on the crucial pathogenic role of vascular endothelial growth factor (VEGF) in the development of diabetic macular edema (DME), intravitreal anti-VEGF agents have emerged as new treatments. To provide an understanding of the rationale for use and clinic...

Photosensitizing medications and photocarcinogenesis.

Photosensitivity is an exaggerated or abnormal response to ultraviolet (UV) or visible light exposure. Many current medications are known photosensitizers; however, the effects of the sensitization can be subclinical and go unnoticed by the person affected. While some of these drugs are used for short and defined periods, others are used indefinitely for the treatment of chronic disease. The question of whether either of these practices translates into an increased risk of skin cancer is an important one. N...

Photosensitivity, Apoptosis, and Cytokines in the Pathogenesis of Lupus Erythematosus: a Critical Review.

The underlying pathomechanisms of lupus erythematosus (LE), a multifactorial autoimmune disease, remain elusive. Due to the clinical evidence demonstrating a clear relationship between ultraviolet (UV) light exposure and skin lesions of LE, photosensitivity has been proven to be an important factor in the pathogenesis of the disease. Standardised photoprovocation with UVA and UVB irradiation has been shown to be a reliable model for evaluating photosensitivity in patients with cutaneous LE (CLE) and analysi...

Minutes, days and years: molecular interactions among different scales of biological timing.

Biological clocks are genetically encoded oscillators that allow organisms to keep track of their environment. Among them, the circadian system is a highly conserved timing structure that regulates several physiological, metabolic and behavioural functions with periods close to 24 h. Time is also crucial for everyday activities that involve conscious time estimation. Timing behaviour in the second-to-minutes range, known as interval timing, involves the interaction of cortico-striatal circuits. In this revi...
