Abstract: We describe here a one month old female child with several dysmorphic features and with a de novo analphoid supernumerary marker chromosome only in cultured skin fibroblast cells and not in lymphocytes. The marker was characterized as analphoid inversion-duplication 3q25.33-qter by oligo array comparative genomic hybridization (aCGH) and fluorescence in situ hybridization (FISH) studies. The final skin fibroblast karyotype was interpreted as 47,XX,+der(3).ish inv dup(3)(qter-q25.33::q25.33-qter)(subtel 3q+,subtel 3q+) de novo.In addition to the eight reported cases of analphoid inversion-duplication 3q supernumerary marker in the literature, this is yet another case of 3q sSMC with a new breakpoint at 3q25.33 and with varying phenotype as described in the case report. Identification of more and more similar cases of analphoid inversion-duplication 3q marker will help in establishing a better genotype-phenotype correlation. The study further demonstrates that aCGH in conjunction with routine cytogenetics and FISH is very useful in precisely identifying and characterizing a marker chromosome, and more importantly help in providing with an accurate genetic diagnosis and better counseling to the family.Small supernumerary marker chromosomes occur in 0.075% of unselected prenatal cases and in 0.044% of consecutively studied postnatal cases, and majority of them are de novo in origin [1-4]. Phenotype of individuals with de novo sSMC vary from normal to extremely mild or severe, depending on the chromosomal region involved and the euchromatic content present [5-7]. Although a number of reports describe the occurrence of a variety of sSMC for nearly all the chromosomes, the number for each type is not large enough to suggest a good genotype-phenotype correlation for a given sSMC, except for inv dup(15) and inv dup(22) where the phenotypic consequences are well described [6,8-10]. We describe here the phenotype and corresponding molecular cytogenetic results of a child with
Influence of Host Management on Downy Mildew Control in Onion
Shabeer Ahmad,Hakim Khan
Pakistan Journal of Biological Sciences , 2001,
Abstract: The interactive effect of three different levels of NPK fertilizer, plant population and irrigation was studied on downy mildew severity and yield of onion. The lowest disease severity was recorded in treatment where NPK 120:90:60 kg/ha, coupled with plant population 0.5 million/ha and eight irrigations. In this treatment the yield and bulb size were also the highest. However, number of bulbs was lower than some other treatments indicating the non-significant effect of disease
Effect of Fungicide Synergy on Downy Mildew Control in Onions
Shabeer Ahmad,Hakim Khan
Pakistan Journal of Biological Sciences , 2000,
Abstract: The synergistic effect of four different fungicides was studied on severity of onion downy mildew under natural field conditions during 1998-99. Area Under Disease Progress Curve (AUDPC) was the highest in treatment where no fungicide was applied. However, it was the lowest in Dithan M-45 + Ridomil. In this treatment bulb yield, bulb size and number of bulbs were also the highest, indicating that fungicide application reduced the disease severity and stabilized onion productivity.
The role of religious, social and political groups in palliative care in Northern Kerala
Sallnow Libby,Chenganakkattil Shabeer
Indian Journal of Palliative Care , 2005,
Abstract: The local community has played an important and central role in the development and determination of palliative care services in Northern Kerala. This article looks at the history of the collaboration and how palliative care services have evolved over the past 4 years from 2001 to 2005. The contribution of groups such as nongovernmental organizations, charities and religious groups is outlined and benefits gained by each side discussed.
Development of an Integrated Disease Management Model for Control of Onion Downy Mildew
Shabeer Ahmad,Hakim Khan
Asian Journal of Plant Sciences , 2002,
Abstract: An integrated disease management model (IDMM) was developed, from the findings of two year research, which included the testing of NPK fertilizer 120:90:60 kg ha -1, plant population 0.5 million plants ha -1, 8 irrigations/season, fungicide Ridomil @ 250 g 100 L -1 plus Antracol/Dithane M-45 @ 200/300 g 100 L -1 and herbicide Ronstar @ 5 ml L -1. This model was verified against Farmers` Own Practices (FOPs) for control of downy mildew of onions. The IDMM reduced the Area Under Disease Progress Curve (AUDPC) and increased substantially bulb size (cm) and bulb yield (t ha -1) by 3.7-4.1 and 20.3-28.2%, respectively. The multi location testing of IDMM proved its superiority over FOPs in minimizing the disease attack and improving the crop yield.
Optimizing Plant Density Cum Weed Control Method For Puccinial Rust Management and Yield in Garlic
Shabeer Ahmad,Javed Iqbal
Asian Journal of Plant Sciences , 2002,
Abstract: Seven different plant densities ( 0.44, 0.53, 0.67, 0.8, 1.0, 1.3 and 2.0 million plants ha-1) and two weed control methods (manual and chemical), compared with no weeding as control, were evaluated in different combinations to find the best interaction for effective rust control and high production in garlic. The lowest value (65.33) of area under disease progress curve (AUDPC) was recorded in treatment where plant population @ 1 million ha-1 and hand weeding were used. Yield (14 t ha-1) and bulb index (4.6 cm) in this treatment were statistically at par with their respective highest values indicating that its performance was better than other treatments in rust control and garlic yield.

In vitro Control of Alternaria solani, the Cause of Early Blight of Tomato
Ashraf Saber Hawamdeh,Shabeer Ahmad
Journal of Biological Sciences , 2001,
Abstract: In vitro control of Alternaria solani was studied with different fungicides. Using Poison Food Technique (PFT), seven fungicides, Antracol, Benlate, Copper oxychloride, Dithane M-45, Ridomil, Topas, and Topsin were evaluated at four different concentrations (250, 500, 750, and 1000 ppm) to control colony growth of fungi . The lowest colony growth was recorded in Dithane M-45 treatment at 1000 ppm, and the highest in treatment where no fungicide was used, indicating the significance of using fungicides in controlling early blight disease in tomato
Impact of Industrial Shut Down and Land Use Change in Chaliyar Basin
Asima Nusrath,A. M. Shabeer
Journal of Geography and Geology , 2011, DOI: 10.5539/jgg.v3n1p247
Abstract: The gradual migration of local labor for jobs abroad has made a remarkable impact on the land use in the local region. The large scale migration was chiefly the outcome of unemployment in the local region as a result of the shutdown of the rayon industry which was the only source of income to the local village community. Two phenomena were observed parallel since 2001. First, the migration pattern of labor force in the study area, and second, the changes in land use pattern. In this background of the problem it is interesting to observe the land use changes through remote sensing during different time periods.
Effect of Time of Application of Dithane M-45 on Control of Black Scurf Disease of Potato
Saima Zeb,Shabeer Ahmad,Shaukat Hussain
Pakistan Journal of Biological Sciences , 2001,
Abstract: The effect of time of application of fungicide Dithane M-45 on black scruf disease and yield in potato was investigated. The fungicide was applied at the rate of 500 ppm two weeks before planting and two weeks after planting the potatoes. All the three were effective in reducing the disease when compared with the control. The fungicide application at the time of planting (T2) showed the lowest incidence (28.37%) and severity (2.71%) of the disease. However, fresh root weight, plant weight, plant height, number of tubers/plant, tuber size and yield were not significantly different in this than other treatments.
