The National Institute of Pharmaceutical Education and Research (NIPER) at S.A.S. Nagar (Mohali) was created as a centre of excellence in imparting higher education, research and development in pharmaceutical sciences and is the first Institute of its kind in the country.
Punjabi University, Patiala, has kept up its spree of winning the highest "A" grade on a four-point scale amongst over 350 universities in the country. The status is awarded by the National Assessment and Accreditation Council (NAAC), which is an autonomous institution of the University Grants Commission, for a period of five years.
The Central Council for Research in Ayurveda & Siddha (CCRAS) is an autonomous body registered on 30th March, 1978 under the Societies Registration Act, XXI of 1860. This Council came into existence after bifurcation of the erstwhile Central Council for Research in Indian Medicine and Homeopathy into four different Research Councils.

Abstract
Alzheimer’s Disease is a neuropathological disorder that causes dementia by progressively degenerating the neurons that are responsible for learning and memory processes. Rivastigmine has demonstrated favorable efficacy and safety in patients with dementia. Nanostructure mediated drug delivery enhances drug bioavailability, improves the timed release of drug molecules, and enables precision drug targeting. Because of its cationic charges, biocompatibility, and low toxicity, chitosan has been used as a vehicle system for genes, protein and drugs. The present study has been undertaken to investigate the targeted delivery of rivastigmine loaded chitosan nanoparticles in streptozotocin induced dementia in mice. Rivastigmine loaded chitosan nanoparticles were prepared by ionic gelation method. The nanoparticles were evaluated for size, shape, zeta potential, microscopy, transmission electron microscopy. Drug-polymer compatibility was determined using differential scanning calorimetry. The amount of drug entrapped within the nanoparticles was determined spectrofluorometrically and in vitro drug release studies were done by spectrofluorometer. Morris Water Maze Test was used to evaluate in vivo activity of rivastigmine nanoparticles in mice. The mean hydrodynamic diameter of chitosan nanoparticles prepared was found to be 258 nm with positive zeta potential value of about 35.1 mV. The entrapment efficiency for various batches of rivastigmine nanoparticles showed a range of 42-84% w/w. Prolonged drug release was observed in case of chitosan nanoparticles. The best release pattern was seen in case of batch A with 1:1 drug : polymer ratio. Rivastigmineloaded Chitosan nanoparticles were found to be effective in STZ induced dementia in mice.

ABSTRACT
Aegle marmelos Corr., a deciduous aromatic tree has been recognized in traditional medicine for the treatment of different diseases and ailments of humans like dysentery, fever, diabetes, asthma, heart problems, ophthalmia, haemorrhoids urinary problems etc. The plant has been reported to contain several phytoconstituents belonging to category of coumarins (like marmenol), alkaloids (like aegeline), glycosides, triterpenoids, anthraquinones, sterols and volatile oils. Several modern scientific studies have authenticated its anti diarrhoeal and gastro protective, anti diabetic, antibacterial, analgesic, anti-inflammatory, antioxidant, anti thyroid, anti histaminic, anti prolifertive and anti fertility activity. Clinical trials of a formulation Diarex (containing A. marmelos has shown positive results patients suffering from diarrhoea and dysentery. This review gives a bird’s eye view mainly on folkloric uses, phytochemistry and pharmacological actions of the plant.
