Abstract:- Compaction of multiparticulate, commonly called MUPS, is one of the more recent and challenging technologies that combine the advantages of both tablets and pellet-filled capsules in one dosage form. Venlafaxine is an anti depressant, having an elimination half-life of 5±2 hrs and its maximum daily dose is 300mg. Since the drug belongs to BCS class I, it is necessary to retard dissolution to ensure extended release of drug. The objective of the study is to prepare venlafaxine extended release pellets by extrusion spheronization technology, coating them with mixture of rate controlling polymers Ethyl cellulose and different grades of (Hydroxy propyl methyl cellulose (HPMC) using Wurster process to achieve the desired dissolution pattern and compressing the pellets into tablets. The pellets were analyzed for the parameters such as bulk density, tapped density, compressibility index, Hausner’s ratio and the results were found to be within the limits. Drug release rate was more when compared with the innovator sample. The Venlafaxine hydrochloride extended release pellets were compressed into the tablets. The dissolution profile of the prepared Venlafaxine hydrochloride extended release tablets were compared with that of Innovator (VENLAR). Finally conclude like extended release pellets in tablets of formulation (F9) have more drug release rate rather than innovator (VENLAR) and it have better Bioavailability.

Abstract:- Wheat flour was used to substitute mushroom flour at the ratio of 70:30, 50:50, 30:70 and with spices (Alllium sativum) which concentration range from 5g, 10g, and 15g respectively. The cookies prepared without wheat flour and mushroom flour serves as positive control. The spread ratios were determined with a meter role. Total viable count, Staphylococcus, Bacillus and colliform count were determine using standard microbiological method and the effect of spices (Alllium sativum) concentration was measured. Consumer preference or otherwise are also determine using a taste panel list. The main quality score of microbial count of the cookies ranges at, 70:30 (1.0x103, 8.0x102 and 6.0x102 cfu for total viable count) (1.5x103, 1.2.x103 and 9.0x102 cfu for fungal count) (1.6x103, 1.2x103 and 1.0x103 cfu for Bacillus count) (1.7x103, 1.6x103, and 1.4x103 cfu for Staphylococcus count) (no count for colliform). At the range of 50:50 (1.3x103, 1.0x103 and 8.0x102 cfu for total viable count) (1.3x103, 1.0x103 and 8.0x102 cfu for Bacillus) (1.85x103,1.65x103 and 1.50x103 cfu for Staphylococcus count). At the range of 30:70 (2.0x103, 1.5x103 and 1.0x103 cfu for total viable) (1.1x103, 9.0x102 and 7.0x102 cfu for fungi count) (1.85x103, 1.50x103, and 1.20x103 cfu for Bacillus count) ( 2.0x103, 1.6x103 and 1.0x103 cfu for Staphylococcus count). The physical quality parameter indicates a range of spread ratio 70:30; 1.283x103, 1.266x103 and 1.250x103, 50:50, (1.250x103, 1.216x103 and 1.183x103). As the spice concentration increases in the order of 5g, 10g and 15g respectively. The main quality sensory score of the cookies ranges of 70:30, colour (5.0, 4.5 and 4.0), flavour (5.0, 4.5 and 4.0), taste (4.5, 4.0 and 3.5), overall acceptability (5.0, 4.0 and 3.5). The range of 50:50, colour (4.5, 4.0 and 3.5), flavour, (4.5, 4.0 and 4.0), taste (3.5, 3.0 and 3.0), overall acceptability (4.0, 3.5 and 3.5).At the range of 30:70, colour (4.0. 3.0 and 2.5), flavour (3.0, 3.0 and 3.0), taste (3.0, 3.0 and 3.0), overall acceptability (3.5, 3.0 and 3.0).

Abstract:- Stability indicating, rapid and reliable derivative, absorption difference and derivative difference spectrophotometric methods were developed for the determination of ofloxacin and ceftriaxone in presence of their degradation products. The linear calibration graphs for ofloxacin were obtained from D1 at 281 nm for the acid solutions, D2 at 288.5 nm for the alkaline solutions, ΔA at 298.6 nm, ΔD1 at 292-304.2 nm, and ΔD2 at 298 nm, while those for its corresponding degradation product were obtained from D2 at 281.5 nm of the acid solutions, and D1 and D2 at 288.5 nm and 297 nm, respectively, for the alkaline solutions. On the other side, ceftriaxone was quantified using D2 amplitudes of the solutions in water at 241.3 nm, D1 at 268.3 nm and 238.5 nm, D2 at 257 nm and 283.4 nm, and D3 at 269.7 nm and 298.3 nm, for the acid solutions, while its corresponding degradation product was determined by measuring the D1 and D2 of the solutions in water at 241 nm and 249.8 nm, respectively, D1 and D3 of the acid solutions at 263 nm for both, D1 at 242.2 nm and 270.3 nm, and D2 at 248.7 nm of the alkaline solutions. The proposed methods were successfully applied to the determination of ofloxacin and ceftriaxone in synthetic mixtures with the corresponding degradation products. The results obtained indicated the high accuracy, calculated as mean percentage recovery, RSD% and Er% and precision; evaluated in terms of inter-day and intra-day precision. In addition, ofloxacin capsules and ceftriaxone ampoules were assayed using the proposed methods and the results obtained were compared with reference spectrophotometric methods.

Abstract:- Background Plantar fasciitis (PF) is an overuse injury causing inflammation at the origin of the plantar fascia and surrounding perifascial structures, such as the calcaneal periosteum, which affects about 10% of the population at least in one moment in life. Successful treatment of plantar fasciitis usually requires combined treatment modalities, rather than administering only one treatment at a time. This study is aimed to examine the effect of medial arch support with ultrasound therapy and exercises to manage plantar fasciitis. Method 10 subjects of both genders, with mean ± SD age of 44.90 ± 4.25years were selected on the basis of inclusion and exclusion criteria. The subjects were under a structured 6 weeks exercise program, medial arch supports and ultra sound therapy for each day for 6-days a week. Result There is statistically significant reduction in foot functional score index measures and improvement in range of motion of ankle joint with p value less than 0.05 after 6 weeks of supervised exercise program, ultra sound therapy and medial arch support. Conclusion The results of the present study, suggest that medial arch support with ultrasound therapy and exercise are effective for plantar fasciitis.

Abstract:- Bacteria are present everywhere in the environment..The aim of the present study is to isolate the air borne bacteria & to check their inhibition by natural plant extracts of Lemon leaves(Citrus limon), Tea leaves(Camelia sinensis) and Ashoka leaves(Saraca asoca). Air borne bacteria were isolated from the Amity University Lucknow campus & were also characterized. Antimicrobial activity was checked using well diffusion method. Plant extracts were prepared from Acetone, Propanol, Methanol & Water. Methanol extract [1] of Saraca asoca was found to be most active against gram positive, anaerobic bacteria giving zone of inhibition of 20mm. It was also found that water extract of Citrus limon was most effective against gram negative, endospore producing, anaerobic bacteria with zone of inhibition of 17mm.
