Background: Epidemiological data on thyroid cancer and associated risk factors are scarce in our setting. The present study was therefore designed to gather data which could be helpful in providing insights to thyroid physicians and surgeons for better management of affected patients. Purpose: To determine the frequency of carcinoma thyroid among patients presenting with goiter and its association with TSH, Tg/ATg and other demographic factors. Materials and Methods: A total of 73 adult patients of either gender with solitary solid cold nodules and/or multi-ndoular goiter (MNG) with predominant solid cold nodules were enrolled. All surgically resected samples were sent for histopathology. The frequency of thyroid cancer and its subtypes was noted and tested for association with gender, age (< or ${\geq}40years$), recent increase in swelling size, TSH, Tg and ATg. Results: Thyroid cancer was diagnosed in 26% (n=19) of the patients, 14 (73.7%) being diagnosed with papillary thyroid cancer and 5 (26.3%) with follicular thyroid cancer. No other subtypes were noted. Presence of thyroid cancer was significantly associated with recent increase in swelling size and higher TSH Values mean TSH values (P<0.05). No significant association was found with gender, age, Tg and ATg values (P>0.05). Conclusions: Overall percentage of thyroid cancer in our study sample was found to be 26%, with a predominance of papillary over follicular lesions. Rates were significantly higher in patients who had history of recent increase in swelling size and higher and higher pre-surgery TSH values.

A great variable response was observed when PP-3 and PP-J encumbered with 116 populations of root knot nematode (RKN) at two different temperatures (25 ± 2°C and 30 ± 2°C) and concentrations (104 and 105 spores/ml). The PCR reaction amplified intergenic region between cytochrome oxidase subunit II gene (COII) and large subunit of rRNA gene (lrRNA) of the mitochondrial genome of different RKN species. The primer C2F3 and 1108 identified M. incognita with the highest frequency (52.6%) followed by M. javanica (36.8%) and M. arenaria (10.5%). The sizes of PCR products were 1.7 kb for M. incognita and M. javanica populations while populations of M. arenaria produced 1.1 kb fragment. The digestion with Hinf I yielded three different fragment length patterns on 1.5 % agarose gel. From current research it is concluded that intra-Meloidogyne genetic variability exist in RKN populations which have better encumbrance with P. penetrans.

Cytoskeleton components in living cell bear large compressive force and are responsible in maintaining the cell shape. Actually these filaments are surrounded by viscoelastic media within the cell. This surrounding, viscoelastic media affects the buckling behavior of these filaments when external force is applied on these filaments by exerting continuous pressure in opposite directions to the incipient buckling of the filaments. In this article a mechanical model is applied to account the effects of this media on the buckling behavior of intermediate filaments network of cytoskeleton. The model immeasurably associates; filament’s bending rigidity, adjacent system elasticity, and cytosol viscosity with buckling wavelength, buckling growth rate and buckling amplitude of the filaments.

A great variable response was observed when PP-3 and PP-J encumbered with 116 populations of root knot nematode (RKN) at two different temperatures ($25{\pm}2^{\circ}C$ and $30{\pm}2^{\circ}C$) and concentrations ($10^4$ and $10^5$ spores/ml). The PCR reaction amplified intergenic region between cytochrome oxidase subunit II gene (COII) and large subunit of rRNA gene (lrRNA) of the mitochondrial genome of different RKN species. The primer C2F3 and 1108 identified M. incognita with the highest frequency (52.6%) followed by M. javanica (36.8%) and M. arenaria (10.5%).

The peach functional beverages pasteurized for10 min at 90 C, microwaved for 1.5 min at 850 W ofpower and sonicated for 90 min at 20 kHz of frequencywere selected to keep in storage for up to 30 days inrefrigerator to examine the changes happened to theirphysicochemical characteristics and functional components. It was observed that the pH and the cloud values ofall processed juice samples reduces with the storage time,whereas, the total soluble solids almost remain consistentparticularly in microwave and ultrasound treated samples. While storage period causes the decrement in total phenoliccontent (TPC) and total flavonoid content of treated beveragesamples, but ultrasound processing showed greaterretention of TPC value up to 5.7% more than other techniquesduring storage. The similar trend was observed forantioxidant activity where the ultrasound treatment showedimproved free radicals (2,2-diphenyl-1-picrylhydrazyl and2,20-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)scavenging activities except ferric ion reducing antioxidantpower after 30 days of storage.

Ionic liquids due to their advantageous properties gain importance in many fields. This study aims tooverview the use of ionic liquids in the selective partial fluorination of organic compounds throughelectrochemical method. In addition to ionic liquid based fluorination, the earlier approaches offluorination through an electrochemical process have also been highlighted. The factors such aselectrode materials (Pt, Ni, and C), types of solvents (CH3CN, DMC, THF, DME, Sulfone, etc.) and type ofelectrolytes (Et3N 3HF, Et3NF 3HF, py HF, etc.) which affect the electrochemical fluorination of organiccompounds have been reviewed. For electrode preparation, the carbon, platinum and nickel wereconsidered suitable materials to be used as an electrode. In CH3CN media, Et3N 3HF and Et4NF 3HFshowed better efficiency during fluorination of organic compounds. Solvent play an important role inelectrochemical fluorination of organic compounds, with the change of solvent the percentage yield ishighly affected. Py-HF is a convenient solvent-supporting electrolyte medium with a reasonably goodconductivity. The electrolyte containing solvents have some side effects on electrochemical fluorinationof organic compounds as observed in cyclic voltammetric analysis. Therefore electrochemicalfluorination to organic compounds without the use of solvent gained more importance. The ionicliquids have been reported for its dual properties, as solvent as well as a fluorinating agent for organiccompounds in electrochemical processes. It has been concluded that solvents free electrochemicalfluorination of organic compounds gives good results as compare to solvent based. Ionic liquids due tomore oxidative stability were noted to have considerable effect on the yield and selectivity of organiccompound fluorination.
