Prostate cancer is reported mainly in men. Based on global cancer statics, it is in the second position compared with other cancers in men. Men below 65 years with mutation in BRCA-2 gene and history of urinary tract infection are more susceptible to prostate cancer. The current treatment includes surgery, radiation therapy, anticancer drugs, hormone therapy, etc. But these led the patients toward infertility. The unique properties in terms of size, surface characteristics, shape, and nanoparticle open a new wave in prostate cancer therapy. Nanoparticle carrier systems can be developed either from natural or synthetic origin. The natural compounds are frequently used for nanoparticle preparation because they are innoxious and did not produce any immune response. Nanoparticle systems that are commonly used include liposomes, polymeric nanoparticles, micelles, dendrimers, carbon-based nanoparticles, etc. The potential of nanoparticle systems provides advanced drug delivery in prostate cancer management.

Workplace noise is hazardous to worker safety and health. Noise can not only cause hearing impairment but also act as a causal factor for stress and raise the systolic blood pressure.There are many methods available and being used in industries at present to reduce acoustic emissions from various equipment. The process of reducing sound emissions from equipment is called acoustic quieting. The method of using piezoelectric material to reduce transmitted sound from equipment rather than damping structural vibration can be applied where it is difficult to damp structural vibrations completely. If piezoelectric materials are attached to vibrating machine parts,withthe supply of suitable voltages, they counter-vibrate which helps in damping structural vibration. Previous studies conducted using simulations with the help of ANSYS software showed noise reductions of up to20 decibels. This paper presentsan effective technique for tuning the frequencies of vibrations of the piezoelectric material with the source vibrations for the reduction of noise. It can help in cancelling the original vibrations which ultimately lead to the reduction in transmitted noise levels. Experiments reveal that a reduction of 9 decibels innoise level is possible by using a filtercontrol circuit.

Vascular malformations are rare congenital vascular anomalies composed of inappropriately connected vasculature. They are usually present at birth, are progressive, infiltrative and require intervention. Vascular malformations need to be differentiated from haemangiomas which are congenital vascular neoplasms. We present a case of vascular malformation in a 6-year old child who presented with a progressive swelling in the neck and was treated by surgical excision. This case is being presented because of its peculiar clinical presentation.

Millimeter-wave wireless communication is an uprising technology. Millimeter-wave has large bandwidth and short wavelength. Eventhough it is advantageous, it gets easily blocked by obstacles. As a result, effective communication does not take place. Relays are used widely to solve this problem. Unmanned Autonomous Vehicles (UAV), such as drones, allows the mobile relays in real applications. It is difficult for relay to find its position quickly and accurately. Here, a method AutoRelay specialized for mmwave communication have been reviewed. In AutoRelay, the link qualities of mmwave beams are sampled while moving. Based on real-time sampling, UAV adjusts its path to reach the optimal location by using compressive sensing theory which increases accuracy and saves time.
