Semaphorins are a large family of proteins originally identified as axon guidance cues which play a crucial role in neural development. They are also ubiquitously expressed beyond the nervous system and contribute to regulation of essential cell functions such as cell migration, proliferation, and adhesion. Binding of semaphorins to their receptors, including plexins and neuropilins, triggers diverse signaling pathways which are involved in the pathogenesis of various diseases from cancer to autoimmune and allergic disorders...

Advances in mechanobiology have evolved through insights from multiple disciplines including structural engineering, biomechanics, vascular biology, and orthopaedics. In this paper, we reviewed the impact of key reports related to the study of applied loads on tissues and cells and the resulting signal transduction pathways. We addressed how technology has helped advance the burgeoning field of mechanobiology (over 33,600 publications from 1970-2016). We analyzed the impact of critical ideas and then determined how these concepts influenced the mechanobiology field by looking at the citation frequency of these reports as well as tracking how the overall number of citations within the field changed over time...

Mogher Khamaisi, Sarit Balanson
Diabetes is a serious disease with severe side effects and comorbidities. Diabetic foot with its chronic non-healing ulcers, or diabetic food ulcers (DFU) as they are commonly called, can be devastating, even leading to amputation. Many therapies exist to assist and improve wound healing. One exciting discovery is the use of negative pressure wound therapy (NPWT) as an adjunct to standard treatment. Few studies have substantively explored the molecular mechanisms of NPWT and why we see improved wound healing, a concept that demands more research...

Polyamines (PAs) are natural compounds involved in many growth and developmental processes in plants, and, specifically in fruits, play a vital role regulating its development, ripening and senescence processes. Putrescine (PUT), spermine (SPE), and spermidine (SPD) are prominent PAs applied exogenously to extend shelf life of fruits. They also originate endogenously during developmental phases of horticultural crops and simultaneously affect the quality attributes and shelf life. Their anti-ethylene nature is being exploited to enhance the shelf life when exogenously applied on fruits...

Globally, there were 14.1 million new cancer diagnoses and 8.2 million cancer deaths in 2012. For many cancers, conventional therapies are limited in their successes and an improved understanding of disease progression is needed in conjunction with exploration of alternative therapies. The long chain polyunsaturated fatty acid, docosahexaenoic acid (DHA), has been shown to enhance many cellular responses that reduce cancer cell viability and decrease proliferation both in vitro and in vivo. A small number of studies suggest that DHA improves chemotherapy outcomes in cancer patients...

Cerebrovascular disease (CVD) remains a leading cause of death and the leading cause of adult disability in most developed countries. This work summarizes state-of-the-art, and possible future, diagnostic and evaluation approaches in multiple stages of CVD, including (i) visualization of sub-clinical disease processes, (ii) acute stroke theranostics, and (iii) characterization of post-stroke recovery mechanisms. Underlying pathophysiology as it relates to large vessel steno-occlusive disease and the impact of this macrovascular disease on tissue-level viability, hemodynamics (cerebral blood flow, cerebral blood volume, and mean transit time), and metabolism (cerebral metabolic rate of oxygen consumption and pH) are also discussed in the context of emerging neuroimaging protocols with sensitivity to these factors...

Among several genetic alterations involved in the progression of prostate cancer, B cell lymphoma gene number 2 (BCL-2) is an important target molecule in the progression of androgen-independent prostate cancer (AIPC) after androgen ablation or castration. Nevertheless, the molecular mechanism of BCL-2 in prostate cancer progression remains elusive and controversial. In the current review, we discuss the critical role of BCL-2 in the carcinogenesis of prostate cancer with experimental evidences on the BCL-2 molecular networks in AIPC and androgen-dependent prostate cancer (ADPC) and subsequently suggest perspective research targeting BCL-2...

Background Hospital waiting times are established instruments to ration healthcare when resources are scarce. However, higher educated patients may be better able to influence access to, and exit from, hospital care when waiting times are long. Methods Based on a representative sample of 11 European countries from the Survey of Health, Ageing and Retirement in Europe (SHARE) collected in 2004/2005, this paper investigates whether the relationship between individual educational background and hospital utilization depends on the prevalent hospital waiting times in a country...

Pressure-induced emission enhancement (PIEE), a novel phenomenon on the enhancement of the solid-state emission efficiency of fluorophores, has been arousing wide attention in recent years. However, researches on PIEE are still in the early stage. To further pursue more enhanced efficiency, discovering and designing more PIEE systems would be urgently desirable and of great importance. In this letter, we found carbazole presented a conspicuous emission enhancement under high pressure up to 1.0 GPa. In situ high-pressure infrared spectroscopy, angle-dispersive X-ray diffraction analysis combined with Hirshfeld surface theory calculation indicated that the PIEE of carbazole was attributed to the decrease of non-radiation vibration process...

A major challenge to achieve effective X-ray radiation therapy is to use a relatively low and safe radiation dose. Various radiosensitizers, which can significantly enhance the radiotherapeutic performance, have been developed. Gold-based nanomaterials, as a new type of nanoparticle-based radiosensitizers, have been extensively used in researches involving cancer radiotherapy. However, the cancer therapeutic effect using the gold nanoparticle-based radiotherapy is usually not significant because of the low cellular uptake efficiency and the autophagy-inducing ability of these gold nanomaterials...

Understanding and engineering the interface between metal and two-dimensional materials are of great importance to the research and development of Nano-electronics. In many cases the interface of meal and 2D materials can dominate the transport behavior of the devices. In this study, we focus on the metal contacts of MoTe2 (molybdenum ditelluride) FETs (field effect transistors) and demonstrate how to use post annealing treatment to modulate their transport behaviors in a controlled manner. We have also carried out low temperature and transmission electron microscopy studies to understand the mechanisms behind the prominent effect of the annealing process...

In the last decade, the research community has witnessed a blooming of targeted genome editing tools and applications. Novel programmable DNA nucleases such as zinc finger nucleases (ZFNs), transcription activator-like endonucleases (TALENs) and the clustered regularly interspaced short palindromic repeats/Cas9 system (CRISPR/Cas9) possess long recognition sites and are capable of cutting DNA in a very specific manner. These DNA nucleases mediate targeted genetic alterations by enhancing the DNA mutation rate via induction of double-strand breaks at a predetermined genomic site...

A transient uterine inflammation post-breeding is a normal physiological reaction in the mare, and it is believed that the inflammatory response is necessary to eliminate bacteria and excess spermatozoa introduced into the uterine lumen. A tight balance between multiple pro- and anti-inflammatory factors is required for resolving the breeding-induced inflammation within 24-36 hr in the reproductively healthy mare, whereas a subpopulation of mares is susceptible to development of a persistent infection that can interfere with fertility...

INTRODUCTION: Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is characterized by congenital absence of the uterus and the upper two-thirds of the vagina in otherwise phenotypically normal females. It is found isolated or associated with renal, skeletal and other malformations. Despite of ongoing research, the etiology is mainly unknown. For a long time, the hypothesis of deficient hormone receptors as cause for MRKHS exists, and is supported by previous findings of our group. The aim of the present study was to identify unknown genetic causes for MRKHS and to compare them with data banks including a review of the literature...
