Sensitive Spectrofluorimetric Method for Determination of Fluoroquinolones through Charge-Transfer Complex Formation  [PDF]
Jasmin Shah, M. Rasul Jan, Inayat Ullah, Sultan Shah
American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.410066
Abstract:

A sensitive spectrofluorimetric method was developed for determination of ciprofloxacin (CPFX), levofloxacin (LEV), gatifloxacin (GAT) and moxifloxacin (MOX) in pure, commercial formulations, human urine and plasma. The method is based on charge-transfer (CT) complex with chloranilic acid. Fluorescence intensity of the complexes was measured at emission wavelength ranging from 445-492 nm with excitation wavelengths from 285-330 nm. At optimum experimental conditions, a linear calibration plot was obtained in the concentration range of 20-1000 ng·mL-1, 60-320 ng·mL-1, 20-800 ng·mL-1 and 20 -00 ng·mL-1 for CPFX, LEV, MOX and GAT, respectively with good correlation coefficient in the range of 0.9929-1.0 in methanolic medium. The limit of detection and limit of quantification were found to be 5 ng·mL-1

Abstract: If is a polynomial of degree , having all its zeros in |z|≤K, K≥1 , then it was proved by Aziz and Rather [2] that for every real or complex number with |a| ≥K, . In this paper, we sharpen above result for the polynomials p(z) of degree n>3
Increased breath ethane and pentane concentrations in currently unmedicated patients with schizophrenia  [PDF]
Brian M. Ross, Sandeep Shah, Malcolm Peet
Open Journal of Psychiatry (OJPsych) , 2011, DOI: 10.4236/ojpsych.2011.11001
Abstract: Schizophrenia is a common and debilitating mental illness. The disorder is thought to be developmental in origin, with oxidative stress being implicated as possible pathophysiological mechanism. Breath alkanes provide a non-invasive means to assess oxidative stress, with ethane levels reportedly increased in medicated patients with schizophrenia. It is possible, however, that the psychotropic medications used to treat the disorder result in elevated breath ethane levels. We have therefore measured the concentration of ethane and pentane, markers of oxidative stress, in the breath of currently unmedicated patients with schizophrenia. Alveolar breath samples were collected, applied to thermal desorption tubes, and analyzed using a combination of two-stage thermal de-sorption, gas chromatography and mass spectrometry. Compared to healthy controls ethane and pentane levels were found to be elevated in patients with schizophrenia, while levels of butane were normal. Our data support the notion that oxidative stress is increased in schizophrenia and that this is unlikely to be a consequence of antipsychotic medications. In addition, breath alkane analysis may represent a rapid and non-invasive means to monitor oxidative stress occurring in schizophrenia.
Response of Wheat to Applied Soil Potassium
M. Tariq,M. Shah
Asian Journal of Plant Sciences , 2002,
Abstract: Response of wheat to applied potassium was studied on Peshawar valley soil. Different levels of potassium @ 0, 30, 60, 90, 120 and 150 kg K2O ha -1 along with a basal dose of nitrogen and phosphorus @ 150 kg N and 100 kg P2O5, respectively were applied to wheat. Results showed that yield and yield components of wheat were not significantly affected with potassium fertilization, because the test soil had already sufficient potassium for plant growth and might be some of K+ released from non-exchangeable sources. However, 60 kg K2O ha -1 gave maximum fresh, dry, straw and grain yields and indicated initial level of K2O supplemented with 60 kg K2O ha -1 was sufficient for maximum yields of wheat for the test soil. Potassium uptake by leaves and potassium content of soils at pre heading and post harvesting stages was significantly increased in a linear fashion with increasing applied potassium levels in soil.
Factors Affecting Visual Outcome Following Surgical Treatment of Cataracts in Children  [PDF]
Mehul A. Shah, Shreya M. Shah, Khushboo A. Shikhangi, Pramod R. Upadhyay, Geetopam B. Bardoloi
Open Journal of Ophthalmology (OJOph) , 2012, DOI: 10.4236/ojoph.2012.24029
Abstract: Purpose: To assess treatment results in pediatric patients with cataracts, to evaluate the efficacy of various surgical interventions, and to determine the factors that affect visual outcomes. Methods: This is aProspective cohort study. We studied a consecutive series of pediatric patients with congenital, developing, or traumatic cataracts who underwent surgery between January, 1999 and April, 2012 at Drashti Netralaya, Dahod. Patient demographics, cataract type, presenting symptoms, surgical intervention, postoperative visual acuity, and follow-up refractive changes were recorded. Results: In total, 1305 eyes of 1047 children were included: unilateral cataracts were present in 786 (60.2%) eyes. There were 610 (46.7%) traumatic and 695 (53.3%) non-traumatic cases. Ages at surgery ranged from 1 to 215 months. Eyes were grouped by the surgical intervention performed: Group 1, pars plana approach including 366 (28%) eyes that underwent lensectomies, and Group 2, anterior approach, including 939 (71.9%) eyes that underwent phacoemulsification ± IOL placement or small incision cataract surgery ± IOL placement. The mean follow-up time was 117 days. Ultimately, 113 (30.9%) Group 1 and 503 (53.6%) Group 2 patients achieved a visual acuity better than 20/60 (P < 0.001). Age at intervention, laterality, sensory nystagmus, pretreatment vision, IOL insertion, and etiology were all significantly related (all P < 0.001) to visual outcome. Conclusions: Surgical treatment with intraocular lens implantation for children with congenital, developmental, or traumatic cataracts is an effective treatment for visual rehabilitation. Visual outcome was significantly better in cases of traumatic cataracts versus non-traumatic cataracts.

Shreya M. Shah, Mehul A. Shah, Pramod R. Upadhyay, Geetopam B. Bardoloi, Drashti Netralaya
Open Journal of Ophthalmology (OJOph) , 2013, DOI: 10.4236/ojoph.2013.31006
Abstract:

Purpose: To investigate the epidemiology of strabismus in cases of pediatric cataracts. To assess visual outcome following orthoptic treatment for amblyopia in cases of cataracts in the pediatric age group. Methods: This was a retrospective cohort study. We investigated a consecutive series of pediatric patients with congenital, developing, or traumatic cataracts who underwent surgery between January 1999 and April 2012 at our center. Patient demographics, cataract type, presenting symptoms, surgical intervention, postoperative visual acuity, and follow-up refractive changes were recorded. Results: In total, 1331 eyes of 1043 children were included: unilateral cataracts were present in 785 (59%) eyes. There were 605 (45.5%) traumatic and 726 (54.5%) non-traumatic cases. Ages at surgery ranged from 1 to 215 months. All eyes were examined for ocular alignment; 66 (5%) were found to manifest strabismus. Deviation was significantly associated with age at intervention (p < 0.001), sensory nystagmus (p < 0.001), and etiology of cataracts (p < 0.001). We found significant differences in visual outcome following amblyopia therapy (p < 0.001).

Auto Disinfectant Cleaner using AVR microcontroller
M. Huned,A. Shah,D. H. Shah
International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: The trend of microcontroller in industrial as well as domestic application is increasing now-a-days. The use of microcontroller is increasing due to the following advantages/features of controller such as Processor reset, Device clocking, central processor, RAM, I/O pins and Instruction cycle timers. There are two types ofmicrocontroller available. They are- Embedded (8,16,32-bit) and Digital Signal Processors. Now-a-days advanced controllers such as PIC, ARM and AVR are widely used in which AVR is used mostly due to several advantages. The disinfectant cleaner used by doctors to clean the medical instruments specially used in Endoscopy are very large in size, bulky and costly. The design of Disinfectant Cleaner is cost effective, light in weight, mobile and user friendly. Atmel AVR 8- and 32-bit microcontrollers deliver a unique combination of performance, power efficiency, and design flexibility. Optimized to speed time to market, they are based on the industry's most code-efficient architecture for C and assembly programming. No other microcontrollers deliver more computing performance with better power efficiency.
