Honggang Qi, Xinyang Fu, Yeping Li, Xiang Pang, Sansan Chen, Xiaojun Zhu, Fei Li, Wanlong Tan
Special AT-rich sequence-binding protein-1 (SATB1) is associated with cancer progression and poor clinical outcome. The present study aims to evaluate whether SATB1 affects the biological behaviors of prostate cancer (PCa), and furthermore, to elucidate whether this effect works through the epithelial-mesenchymal transition (EMT) pathway. Firstly, the expression of SATB1 was investigated in a series of PCa tissues as well as in a panel of PCa cell lines. Cell proliferation, migration and invasion were evaluated in SATB1 knockdown and overexpressed PCa cell lines by MTT and Transwell assays...

Patients with peripheral arterial occlusive disease who show an ankle arterial pressure of minimum 60 mmHg can be decongested by use of special padded bandages. Afterwards, medical compression stockings (class 1) with high strength and less elasticity are recommended. Mobile patients seem to benefit from progressive compression therapy with highest pressure above the calf. Compression after uncomplicated interventions of varicose veins or spider veins tends to be modified to a short and excentric compression in patients without risk factors...

Cardiomyopathies often have a genetic etiology. New genetic diagnostic strategies based on next generation sequencing (NGS)-approaches will continuously increase our knowledge about the genetic basis of cardiomyopathies within the following years. Diagnostics and therapy of rare, genetically-induced cardiac diseases increasingly require special cardiac and genetic knowledge. Interestingly, mutations in the same gene or even identical gene mutations can be associated with different cardiomyopathy phenotypes and can exhibit incomplete penetrance or variable expressivity...

Sébastien Loranger, Raman Kashyap
Many applications of optical fiber, such as specialized fiber Bragg gratings (FBGs), require high uniformity of a fiber's refractive index (RI) along its length. We show here that the mode effective index of most fibers is not constant, even on a short length scale. To help improve fiber manufacturing and selection, we demonstrate a technique for characterizing a meter length single-mode optical fiber's effective RI over a centimeter scale with a precision of 3×10<sup>-6</sup> RI units (RIUs) and an absolute accuracy of 2×10<sup>-4</sup> RIU...

Hollow core fibers are considered as promising candidates to deliver intense temporally overlapping picosecond pulses in applications such as stimulated Raman scattering (SRS) microscopy and endoscopy because of their inherent low nonlinearity compared to solid-core silica fibers. Here we demonstrate that, contrary to prior assumptions, parasitic signals are generated in Kagomé lattice hollow core fibers. We identify the origin of the parasitic signals as an interplay between the Kerr nonlinearity of air and frequency-dependent fiber losses...

Song Tang, Lianping Hou, Xiangfei Chen, John H Marsh
Special designs of sampled Bragg gratings have been used to fabricate distributed-feedback semiconductor laser arrays with very precise wavelength spacing and strong coupling coefficients. By dividing one sampling period into two equal sections, each with a grating but with a π-phase shift between the sections, the ±1st-order channels are enhanced while eliminating the zeroth-order reflection. By using multiple phase-shifted sections, only the -1st-order channel is enhanced. Using a single electron beam lithography step and two π-phase-shifted sections, we have fabricated an eight-channel laser array with a channel spacing of 100 GHz...

Hemoglobin S/Black ((A) γδβ)(0) -thalassemia is a rare sickle cell disease (SCD) variant. On the basis of limited descriptions in the literature, the disease is reported as a mild microcytic anemia with an uncomplicated course. We report the clinical and laboratory data of nine patients whose diagnoses were confirmed by DNA-based techniques. Despite having mild anemia and high fetal hemoglobin level postinfancy, these patients developed many of the classic complications of SCD, including vaso-occlusive crisis, acute chest syndrome, avascular necrosis, and cholelithiasis...

Seongjin Seo, Poppy Datta
The photoreceptor outer segment (OS) is a unique modification of the primary cilium, specialized for light perception. Being homologous organelles, the primary cilium and the OS share common building blocks and molecular machinery to construct and maintain them. The OS, however, has several unique structural features that are not seen in primary cilia. Although these unique features of the OS have been well documented, their implications in protein localization have been under-appreciated. In this review, we compare the structural properties of the primary cilium and the OS, and propose a hypothesis that the OS can act as a sink for membrane proteins...

Sterols are key cyclic triterpenoid lipid components of eukaryotic cellular membranes, which are synthesized through complex multi-enzyme pathways. Similar to most animals, Bathymodiolus mussels, which inhabit deep-sea chemosynthetic ecosystems and harbor methanotrophic and/or thiotrophic bacterial endosymbionts, possess cholesterol as their main sterol. On the basis of stable carbon isotope analyses, it has been suggested that host Bathymodiolus mussels synthesize cholesterol using a sterol intermediate derived from the methanotrophic endosymbionts...

Plant specialized metabolites are chemically highly diverse, play key roles in host-microbe interactions, have important nutritional value in crops and are frequently applied as medicines. It has recently become clear that plant biosynthetic pathway-encoding genes are sometimes densely clustered in specific genomic loci: biosynthetic gene clusters (BGCs). Here, we introduce plantiSMASH, a versatile online analysis platform that automates the identification of candidate plant BGCs. Moreover, it allows integration of transcriptomic data to prioritize candidate BGCs based on the coexpression patterns of predicted biosynthetic enzyme-coding genes, and facilitates comparative genomic analysis to study the evolutionary conservation of each cluster...

Bioartificial liver holds special position in the field of regenerative medicine, and cold environment at 4℃ is widely used for the short storage of both organ and liver cell for later application. However, the disadvantages of such cold storage could influence cell viability and lead to cell apoptosis in different degrees. In this study, we mainly explore the pre-protective effect of mild hypothermia against low temperature (4℃)-induced rat liver cell injury in vitro. Our results indicated that the precondition with mild hypothermia could increase cell viability, such as cell proliferation, LDH regulation and glycogen synthesis ability of liver cell...

Breast cancer in young women is a complex disease to manage due to its biological heterogeneity and special issues related to toxicity of different treatment strategies. Defining a cut-off for young age has been challenging since it is not clear whether the prognostic effect of age is continuously variable or whether there are certain thresholds at which the prognosis changes (e.g. those < 50 years of age or ≤ 35 years of age). In this review article, we define young patients as those being premenopausal...

BACKGROUND: Eph receptors comprise the largest group of the receptor tyrosine kinase (RTK) family, and Eph receptors interacting with their ligand ephrins play an important role in development and tumorigenesis. EphB6, a special Eph receptor that lacks tyrosine kinase activity, was reported to be expressed in some human cancers. The clinical significance of EphB6 in gastric carcinoma has not been well investigated. METHODS: In this study, we detected expression of EphB6 protein in four gastric cancer cell lines and a set of gastric carcinoma tissue specimens by using immunohistochemistry...

Brown adipose tissue (BAT) mitochondria are distinct from their counterparts in other tissues in that ATP production is not their primary physiologic role. BAT mitochondria are equipped with a specialized protein known as uncoupling protein 1 (UCP1). UCP1 short-circuits the electron transport chain, allowing mitochondrial membrane potential to be transduced to heat, making BAT a tissue capable of altering energy expenditure and fuel metabolism in mammals without increasing physical activity. The recent discovery that adult humans have metabolically active BAT has rekindled an interest in this intriguing tissue, with the overarching aim of manipulating BAT function to augment energy expenditure as a countermeasure for obesity and the metabolic abnormalities it incurs...

Sleep disturbances such as insomnia, hypersomnia, and circadian rhythm disturbance are common in normal elderly and Alzheimer's disease (AD) patients. To date, special attention has been paid to sleep disturbance in the clinical course of AD insofar as the interaction of sleep disturbance with the pathogenesis of AD may impact the clinical course and cognitive function of AD patients. This review covers the bidirectional relationship between sleep disturbance and AD pathogenesis; the associations between sleep disturbance and AD-specific neurotransmitters, brain structure, and aspects of sleep disturbance in each phase of AD; and the effects of sleep disturbance on the cognitive functions of patients in each phase of AD...

EDITORIAL
Abby Koch, William Checkley
Since the inception of critical care as a formal discipline in the late 1950s, we have seen rapid specialization to many types of intensive care units (ICUs) to accommodate evolving life support technologies and novel therapies in various disciplines of medicine. Indeed, the field has expanded such that specialized ICUs currently exist to address critical care problems in medicine, cardiology, neurology and neurosurgery, trauma, burns, organ transplant and cardiothoracic surgeries. Specialization does not only need new infrastructure, but also training and staffing of health care providers, ancillary staff, and development and implementation of processes of care...

Pheochromocytomas are catecholamine-producing neuroendocrine tumors that usually occur in the adrenal medulla or sympathetic paraganglia. Anterior mediastinum involvement with pheochromocytoma is rare and may not present with typical symptoms. Its clinical manifestation may be unclear and a high index of suspicion is required for accurate diagnosis. We report a rare case of pheochromocytoma of the anterior mediastinum in a 51-year-old female. A painful hard mass on the sternum was the only clinical manifestation...

The neuromuscular junction (NMJ) is indispensable for survival. This synapse between motoneurons and skeletal muscle fibers allows posture, movement and respiration. Therefore, its dysfunction creates pathologies than can be lethal. The molecular mechanisms of NMJ development and maintenance are the subject of intensive studies. This mini-review focuses on some of the most recent discoveries. An unexpected role for a protein, rapsyn, which has been known for 40 years to aggregate acetylcholine receptors has emerged...
