The photobiology of Heterosigma akashiwo. Photoacclimation, diurnal periodicity, and its ability to rapidly exploit exposure to high light.

Journal of phycology

Hennige SJ, Coyne KJ, MacIntyre H, Liefer J, Warner ME.
PMID: 27008521
J Phycol. 2013 Apr;49(2):349-60. doi: 10.1111/jpy.12043. Epub 2013 Feb 25.

Periodic and seasonal exposure to high light is a common occurrence for many near-shore and estuarine phytoplankton. Rapid acclimatization to shifts in light may provide an axis by which some species of phytoplankton can outcompete other microalgae. Patterns of...

Pill MF, Schmidt SW, Beyer MK, Clausen-Schaumann H, Kersch A.
PMID: 25669537
J Chem Phys. 2014 Jan 28;140(4):044321. doi: 10.1063/1.4862827.

To elucidate the mechanism of the mechanically activated dissociation of chemical bonds between carboxymethylated amylose (CMA) and silane functionalized silicon dioxide, we have investigated the dissociation kinetics of the bonds connecting CMA to silicon oxide surfaces with density functional...

On Biophysical Properties and Sensitivity to Gap Junction Blockers of Connexin 39 Hemichannels Expressed in HeLa Cells.

Front Physiol. 2017 Feb 09;8:38. doi: 10.3389/fphys.2017.00038. eCollection 2017.

Although connexins (Cxs) are broadly expressed by cells of mammalian organisms, Cx39 has a very restricted pattern of expression and the biophysical properties of Cx39-based channels [hemichannels (HCs) and gap junction channels (GJCs)] remain largely unknown. Here, we used...

Beilstein J Nanotechnol. 2016 Mar 07;7:364-373. doi: 10.3762/bjnano.7.33. eCollection 2016.

Proteases, including matrix metalloproteinases (MMPs), tissue serine proteases, and cathepsins (CTS) exhibit numerous functions in tumor biology. Solid tumors are characterized by changes in protease expression levels by tumor and surrounding tissue. Therefore, monitoring protease levels in tissue samples...

White matter relapsing remitting disease: "Susac's syndrome"-An underdiagnosed entity.

Multiple sclerosis and related disorders

Susac's syndrome is a treatable microangiopathy of unknown etiology affecting arterioles of the brain, retina, and cochlea. The typical clinical manifestation is the triad of encephalopathy, visual loss, and sensorineural hearing loss. One or more of these features may...

Molecular Modeling of Structures and Interaction of Human Corticotropin-Releasing Factor (CRF) Binding Protein and CRF Type-2 Receptor.

Frontiers in endocrinology

Front Endocrinol (Lausanne). 2018 Feb 20;9:43. doi: 10.3389/fendo.2018.00043. eCollection 2018.

The corticotropin-releasing factor (CRF) system is a key mediator of the stress response and addictive behavior. The CRF system includes four peptides: The CRF system includes four peptides: CRF, urocortins I-III, CRF binding protein (CRF-BP) that binds CRF with...

Schwannoma in the porta hepatis - laparoscopic excision under laparoscopic ultrasound guidance.

Wideochirurgia i inne techniki maloinwazyjne = Videosurgery and other miniinvasive techniques

Sebastian M, Sroczyński M, Donizy P, Rudnicki J.

Schwannomas are usually benign tumors attached to peripheral nerves and are rarely found in the gastrointestinal tract. Schwannomas in the porta hepatis are extremely rare, with only 15 cases described in the literature to date. A 22-year-old female patient...

Rising prevalence of non-B HIV-1 subtypes in North Carolina and evidence for local onward transmission.

Virus evolution

PMID: 28567304
Virus Evol. 2017 May 24;3(1):vex013. doi: 10.1093/ve/vex013. eCollection 2017 Jan.

HIV-1 diversity is increasing in North American and European cohorts which may have public health implications. However, little is known about non-B subtype diversity in the southern United States, despite the region being the epicenter of the nation's epidemic....

Enhanced spectral sensitivity of a chip-scale photonic-crystal slow-light interferometer.

Optics letters

Opt Lett. 2016 Apr 01;41(7):1431-4. doi: 10.1364/OL.41.001431.

We experimentally demonstrate that the spectral sensitivity of a Mach-Zehnder (MZ) interferometer can be enhanced through structural slow light. We observe a 20-fold resolution enhancement by placing a dispersion-engineered, slow-light, photonic-crystal waveguide in one arm of a fiber-based MZ...

Nuclear Velocity Perturbation Theory of Vibrational Circular Dichroism.
