A newly approved drug for a rare group of diseases: Dichlorphenamide for periodic paralysis

orlsfakianakisστοOtoRhinoLaryngology by Sfakianakis G.AlexandrosΠριν από 47 δευτερόλεπτα
The periodic paralyses constitute a group of autosomal dominantly inherited myopathies characterized by acute and reversible attacks of muscle weakness associated with changes in serum potassium levels. In addition to paralytic episodes, patients may develop persistent and progressive muscle weakness. Over the past 2 decades, the periodic paralyses have been models for basic and translational… Continue reading A newly approved drug for a rare group of diseases: Dichlorphenamide for periodic paralysis

Urinary LRRK2 phosphorylation: Penetrating the thicket of Parkinson disease?

While the discovery of the first monogenic cause of Parkinson disease (PD) almost 2 decades ago has revolutionized our understanding of this increasingly prevalent disorder, genotype–phenotype relationships have proven to be much more complex than initially anticipated. An important reason for this observation is reduced penetrance, a conundrum referring to the surprisingly large proportion of […]

Migrated Implant Causing Refractory Headache in Rhinoplasty: Facial plast Surg 2016; 32: 117-120 DOI: 10.1055/s-0035-1570121 Alloplastic materials are popular and readily available for use in nasal augmentations. Among them, silicone implant is one of the most widely used, especially in certain areas in Asia for its reasonable cost and relatively simple operative technique. A major disadvantage of silicone is its notorious mobility after implantation and rate of extrusion if traumatized or exposed. Here, an unusual complication of a silicone implant for rhinoplasty was presented. W... περισσότερα »

Rhinoplasty of the Aging Nose: Facial plast Surg 2016; 32: 059-069 DOI: 10.1055/s-0035-1570126 The process of aging leads to countless bodily changes on both a macro- and microscopic scale. No organ system is unaffected; however, the nose is especially susceptible. Sun damage, hormone levels, regenerative capability, tissue elasticity, bone resorption, and the effects of gravity contribute to produce classic signs and symptoms. Rhinoplasty of the aging nose requires a comprehensive understanding of aging facial anatomy combined with surgical techniques designed to resist these ubiq... περισσότερα »

Hypothyroidism and hyperthyroidism and breast cancer risk: a nationwide cohort study

Objective The association between thyroid disease and breast cancer risk remains unclear. We, therefore examined the association between hypothyroidism, hyperthyroidism and breast cancer risk. Design This was a population-based cohort study. Methods Using nationwide registries, we identified all women in Denmark with a first-time hospital diagnosis of hypothyroidism or hyperthyroidism, 1978–2013. We estimated the excess […]

Ca2+ removal by the plasma membrane Ca2+-ATPase influences the contribution of mitochondria to activity-dependent Ca2+ dynamics in Aplysia neuroendocrine cells

Following Ca2+ influx, mitochondria can sequester Ca2+ and subsequently release it back into the cytosol. This form of Ca2+-induced Ca2+-release (CICR) prolongs Ca2+ signaling and can potentially mediate activity-dependent plasticity. As Ca2+ is required for its subsequent release, Ca2+ removal systems, like the plasma membrane Ca2+ ATPase (PMCA), could impact CICR. Here, we examine such […]

Precaution for volume conduction in rodent cortical electroencephalography using high density polyimide-based micro-electrode arrays on the skull

In humans, significant progress has been made to link spatial changes in electroencephalographic (EEG) spectral density, connectivity strength and phase-amplitude modulation to neurological, physiological and psychological correlates. In contrast, standard rodent EEG techniques employ only few electrodes which results in poor spatial resolution. Recently a technique was developed to overcome this limitation in mice. This […]

Neuronal Responses to Tactile Stimuli and Tactile Sensations evoked by Microstimulation in the Human Thalamic Principle Somatic Sensory Nucleus – Ventral caudal

The normal organization and plasticity of the cutaneous core of the thalamic principal somatosensory nucleus (ventral caudal, Vc) have been studied by single neuron recordings and microstimulation in patients undergoing awake stereotactic operations for essential tremor (ET) without apparent somatic sensory abnormality, and in patients with dystonia or chronic pain secondary to major nervous system […]

Long-latency reflexes of elbow and shoulder muscles suggest reciprocal excitation of the flexors and reciprocal excitation of the extensors

In response to stressful conditions, eukaryotic cells launch an arsenal of regulatory programs to protect the proteome. One major protective response involves the arrest of protein translation and the formation of stress granules, cytoplasmic ribonucleoprotein complexes containing the conserved RNA-binding proteins TIA-1 and TIAR. The stress granule response is thought to preserve mRNA for translation when conditions improve. For cells of the germline, the immortal cell lineage required for sexual reproduction, protection from stress must be critically important for perpetuation of... περισσότερα »

Thyroid hormone controls many activities in your body, including how fast you burn calories and how fast your heart beats. Diseases of the thyroid cause it to make either too much or too little of the hormone.

PERK Integrates Oncogenic Signaling and Cell Survival During Cancer Development

Alexandros G. SfakianakisστοEvolutionary PhysiologyΠριν από 1 ώρα
Abstract Unfolded protein responses (UPR), consisting of three major transducers PERK, IRE1 and ATF6, occur in the midst of a variety of intracellular and extracellular challenges that perturb protein folding in the endoplasmic reticulum (ER). ER stress occurs and is thought to be a contributing factor to a number of human diseases, including cancer, neurodegenerative disorders and various metabolic syndromes. In the context of neoplastic growth, oncogenic stress resulting from dysregulation of oncogenes such as c-Myc, BrafV600E and HRASG12V trigger the UPR as an adaptive strategy ... περισσότερα »

Dynamic Histone Acetylation of H3K4me3 Nucleosome Regulates MCL1 Pre-mRNA Splicing

Alexandros G. SfakianakisστοEvolutionary PhysiologyΠριν από 1 ώρα
Abstract Pre-mRNA splicing is a cotranscriptional process affected by the chromatin architecture along the body of coding genes. Recruited to the pre-mRNA by splicing factors, histone deacetylases (HDACs) and K-acetyltransferases (KATs) catalyze dynamic histone acetylation along the gene. In colon carcinoma HCT 116 cells, HDAC inhibition specifically increased KAT2B occupancy as well as H3 and H4 acetylation of the H3K4 trimethylated (H3K4me3) nucleosome positioned over alternative exon 2 of the *MCL1* gene, an event paralleled with the exclusion of exon 2. These results were repr... περισσότερα »

High cystatin C levels predict undesirable outcome for diabetic foot ulcerations

Abstract We investigated the relationship between serum cystatin C levels and the prognosis of diabetic foot ulcerations (DFU). A population-based cohort study involving 1018 patients with type 2 diabetes was conducted. These patients recruited and divided into two groups: non-diabetic-foot ulcer group (NDF,n=865,85.5%) and diabetic foot ulcer group (DFU, n=147,14.5%).After a 1-year-follow-up,DFUs were grouped into […]

Potential role of systemic thrombolysis in acute submassive intermediate risk pulmonary embolism: review and future perspectives

Submassive (intermediate risk) pulmonary embolism (PE) continues to be a significantly morbid disease process that remains unrecognized, inadequately risk stratified and suboptimally treated. Appropriate early clinical and imaging-based risk stratification represents the cornerstone for adequate therapeutic decision making, particularly for the selection of candidates who may benefit the most from systemic thrombolysis. The relevance of […]
