In the field of optical computing and parallel information processing, several number systems have been used for different arithmetic and algebraic operations. Therefore an efficient conversion scheme from one number system to another is very important. Modified trinary number （MTN） has already taken a significant role towards carry and borrow free arithmetic operations. In this communication, we propose a tree-net architecture based all optical conversion scheme from binary number to its MTN form. Optical switch using nonlinear material （NLM） plays an important role.

In this letter,the authors propose a new concept of implementing all-optical logic gates by representing the logic states with polarization of an optical signal .As the state of polarization of the light signal is very much suitable for encoding and detecting the bits of data of a digital signal in communication,the scheme may extend some wide applications in all-optical parallel computation and information processing.

The importance of extracellular vesicles(EVs) in cell-cell communication has long been recognized due to their ability to transfer important cellular cargoes such as DNA, mRNA, miRNAs, and proteins to target cells. Compelling evidence supports the role of EVs in the horizontal transfer of cellular material which has the potential to influence normal cellular physiology and promote various disease states. Of the different types of EVs, exosomes have garnered much attention in the past decade due to their abundance in various biological fluids and ability to affect multiple organ systems. The main focus of this review will be on cancer and how cancer-derived exosomes are important mediators of metastasis, angiogenesis, immune modulation, and the tumor macro-/microenvironment. We will also discuss exosomes as potential biomarkers for cancers due to their abundance in biological fluids, ease of uptake, and cellular content. Exosome use in diagnosis, prognosis, and in establishing treatment regimens has enormous potential to revolutionize patient care.

We propose a new integrated method which covers addition of any two signed digit numbers in all-optical domain. To implement this scheme we have exploited some photo-refractive characters of optical non-linear materials,which may experience 0.1-0.2dB attenuation loss as silica is used as non-linear medium. Moreover,the attenuation loss may be reduced to 0.001 dB/m if we consider the use of slow light at 1.56μm.

Amyloid precursor protein intracellular domain （AICD） is one of the potential candidates in deciphering the complexity of Alzheimer＇s disease. It plays important roles in determining cell fate and neurodegeneration through its interactions with several adaptors. The pres- ence or absence of phosphorylation at specific sites determines the choice of partners. In this study, we identified 20 novel AICD- interacting proteins by in vitro pull down experiments followed by 2D gel electrophoresis and MALDI-MS analysis. The identified proteins can be grouped into different functional classes including molecular chaperones, structural proteins, signaling and transport molecules, adaptors, motor proteins and apoptosis determinants. Interactions of nine proteins were further validated either by colocal- ization using confocal imaging or by co-immunoprecipitation followed by immunoblotting. The cellular functions of most of the proteins can be correlated with AD. Hence, illustration of their interactions with AICD may shed some light on the disease pathophysiology.
