Neurobiology: The Eye within the Brain.

All vertebrates except mammals have photoreceptors within their brains; however, the light-sensitive cells have never been unambiguously identified. A new paper provides direct evidence of photosensitivity in cerebrospinal fluid (CSF)-contacting neurons in quail brain that mediate the seasonal reproductive response.

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...

Intrinsic photosensitivity of a deep brain photoreceptor.

In addition to having a photoreceptive retina and pineal organ, non-mammalian vertebrates are known to have photoreceptors in the deeper regions of the brain that mediate seasonal changes in physiology and behavior [1]. Cerebrospinal fluid (CSF)-contacting neurons extend knob-like dendrites into the ventricular cavity, where they form ciliated terminals [2]. The dendritic structures of photoreceptor cells in the developing retina and the pineal organ resemble those of CSF-contacting neurons. Thus, CSF-conta...

Oligopeptides as Biomarkers of Cyanobacterial Subpopulations. Toward an Understanding of Their Biological Role.

Cyanobacterial oligopeptides comprise a wide range of bioactive and/or toxic compounds. While current research is strongly focused on exploring new oligopeptide variants and their bioactive properties, the biological role of these compounds remains elusive. Oligopeptides production abilities show a remarkably patchy distribution among conspecific strains. This observation has prompted alternative approaches to unveil their adaptive value, based on the use of cellular oligopeptide compositions as biomarkers ...

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...

Acute Phototoxic Reaction in a Century Cyclist.

: Medications can cause photosensitivity. Several of these medications, specifically the nonsteroidal anti-inflammatory medications (NSAIDs), may be taken by athletes to treat joint and muscle discomfort. Many athletic events occur outdoors, which in turn exposes athletes to sunlight. Athletes taking NSAIDs and performing extensive outdoor activities may be at higher risk for phototoxic drug reactions. Clinicians may wish consider the potential for patient photosensitivity when recommending prescription and...

Genome scale modeling in systems biology: algorithms and resources.

In recent years, in silico studies and trial simulations have complemented experimental procedures. A model is a description of a system, and a system is any collection of interrelated objects; an object, moreover, is some elemental unit upon which observations can be made but whose internal structure either does not exist or is ignored. Therefore, any network analysis approach is critical for successful quantitative modeling of biological systems. This review highlights some of most popular and important m...

Biological findings from the recent NMR-based studies of glycosaminoglycanprotein interactions.

Besides regulating multiple physiological processes like cellular growth, migration and differentiation, glycosaminoglycans (GAGs) are also largely explored in the global market as clinical or nutraceutical agents. Generally, these physiological and biomedical events are ultimately triggered by the quality and nature of molecular interactions between GAGs and functional proteins. Nuclear magnetic resonance (NMR) spectroscopy participates significantly in the investigations of the most carbohydrate-protein i...

Photosensitivity in mild traumatic brain injury (mTBI): A retrospective analysis.

Abstract Primary objective: To determine whether photosensitivity (PS) changes over time and, if so, what factors may be related to the change; furthermore, to determine whether tint density changes over time, all in mild traumatic brain injury (mTBI). Design and methods: A retrospective analysis of 62 patient records (aged 18-40 years) with mTBI and PS was conducted. All charts were obtained from the SUNY/College of Optometry clinics from 2004-2011. Results: Fifty per cent demonstrated reduced PS over time...

Biological Messiness vs. Biological Genius: Mechanistic Aspects and Roles of Protein Promiscuity.

In contrast to the traditional biological paradigms focused on 'specificity,' recent research and theoretical efforts have focused on functional 'promiscuity' exhibited by proteins and enzymes in many biological settings, including enzymatic detoxication, steroid biochemistry, signal transduction and immune responses. In addition, divergent evolutionary processes are apparently facilitated by random mutations that yield promiscuous enzyme intermediates. The intermediates, in turn, provide opportunities for ...
