2. Polymeric In-situ
Gels as Smart Carriers for Pesticide Delivery in Agricultural Practice
Hari B.N.V., Lobo F.J., Devi D.R.
Agriculture is the backbone of our economic system which had been associated with the production of basic food crops. Tremendous benefits have been derived from the use of pesticides in agriculture, forestry and other sectors. They are used to control pests, diseases and weeds, but conventional pesticides can contaminate surface water through runoff from treated plants and soil which results in incomplete release of the molecules and short residence time at the required sites. To overcome this drawback and to maximize the utilization of these pesticides, in-situ
gel formulation would be an effective alternative. In-situ
gelling polymeric delivery system is a novel technique in which the active ingredient present in the form of solution gets converted into a gel upon application to the site of action. The formation of gel depends on factors like temperature modulation, pH change, presence of ions and ultra violet irradiation; the in-situ
gel formulation can sustain the release and also reduce the frequency of administration. So it is widely applied in drug delivery for ophthalmic, nasal, rectal and vaginal route of administration for improving both local and systemic effects of drug, and thereby its bioavailability. The objective of this review is to explore such new trends adapted for pesticide delivery systems to enhance the food production. Recently, these types of approaches are being explored in pesticide delivery systems to control various infections.

Laouini Salah Eddine, Ladjel Segni, Ouahrani Mohammed Ridha
This study was aimed at investigating the preliminary phytochemical screening, total phenolic and condensed tannins constituents, antioxidant, antibacterial and antifungal by using various in vitro systems and analysis of marker compounds by High performance liquid chromatography (HPLC) of methanolic, ethanolic and petroleum ether extracts of Asphodelus tenuifolius
Cav (ATC). Antioxidant efficacies of three extracts were estimated by their abilities to scavenge DPPH˙ and total antioxidant activity expressed by reducing Mo (VI) to Mo (V). The antimicrobial activity of the methanolic, ethanolic and petroleum ether extracts of ATC was determined against eleven strains including Gram-positive and Gram negative bacteria as well as yeasts. The phenolic contents of the extracts as vanillin were found to be highest in methanol (68.15%) followed by ethanol (53.8%) and petroleum ether extract (1.56%). the antioxidant and free radical scavenging activities of the extracts assayed through DPPH˙ method were also found to be highest with methanol extracts followed by ethanol and petroleum ether extracts. For the antibacterial and antifungal activity the extracts showed moderately activity, compared to standard antibiotics, inhibiting all tested bacteria except Pseudomonas aerigunosa
. The most sensitive microorganism was Staphylococcus aureus
(diameter of inhibition is 16 mm) showed in methanolic extract at 4 mg/ml. To our knowledge, this is the first report on the biological activities of Asphodelus tenuifolius
Cav extract and our findings suggest the possibility of using the aerial parts as a novel source of natural antimicrobial and antioxidant agents for the food and pharmaceutical industries.

6. Endodontic Stabilizers: A Myth
Nivethithan. T, Sindhu Ramesh, James D. Raj
Endodontic implants or stabilizers are metallic extension of the tooth root into the bone. With increase in the scope of implantology in dentistry, the endodontic implants help provide a conservative treatment method to retain a natural teeth rather than replacing it. These endodontic implants are inserted through the previously prepared canals of the tooth into the osseous portion of the periodontium just like a conventional implant. They are indicated mostly in severely mobile teeth in an aim to retain the natural teeth rather than extracting and replacing it with an endosseous implant. These endodontic implants, even though having very good success in some cases had encountered failure due to many factors which made the practitioners not to consider them as a primary mode of treatment. This article tends to assess the success and failure of endodontic implants by reviewing various case reports and studies presented over the time.
