Feasibility of Intercropping Mungbean (Vigna radiata) in Guara (Syamopsis psoraliodes)
Himayat Ullah Khan,Muhammad Ayub,Muhammad Qasim,Muhammad Subhan
Journal of Biological Sciences , 2001,
Abstract: Guara sown at 45 cm spaced double-row strips with two rows of intercropped Mungbean produced significantly more No. of pods, heavier grains and maximum grain yield. Mungbean sown between 45, 60 and 75 cm spaced double, triple and four row strips of Guara respectively, did not significantly effect No. of pods, thousand grain weight and grain yield per plant.
Comparison of the Gene Action Controlling Metric Characters in Upland Cotton (Gossypium hirsutum L.)
Muhammad Subhan,Himayat Ullah Khan,Riazud Din Ahmad
Pakistan Journal of Biological Sciences , 2000,
Abstract: Significant differences among hybrids and their parents were noted. Th boll weight and staple length reflected additive type of gene action while in seed index and lint index, over-dominance gene action was observed. The non-significant deviation of regression line from unit slope indicates the absence of non-allelic interaction in staple length showing absence of epistatsis providing positive lines for isolating superior genotypes. Boll weight and lint index shows the significant deviation from unit slope which surely indicates the presence of opitstasis.
Biological and Pharmacological Properties of Aconitum chasmanthum
Saeed Anwar,Bashir Ahmad,Muhammad Subhan,Waseem Gul
Journal of Biological Sciences , 2003,
Abstract: Crude methanolic (90%) extract of Aconitum chasmanthum as well as various fractions of the same obtained by using different solvent systems were screened for biological and pharmacological activities such as antifungal, antibacterial, insecticidal and Brine shrimp cytotoxic activities. It was observed that the antifungal activity varies from negligible to strong depending upon the solvent system used for the extraction. All the fractions exhibited remarkable antifungal activity against Trichophyton mentagrophyte. However the activity against other organisms varies from no activity to strong inhibition. Antibacterial, insecticidal activities and Brine shrimp cytotoxicity results are also presented.

Tahir Usman,Gang Guo,Syed Muhammad Suhail,Muhammad Subhan Qureshi,Yachun Wang
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.3132.3139
Abstract: The present study was aimed at estimation of the genetic parameters and the effect of season and year of birth on performance traits of Holstein Friesian cattle maintained at Agricultural University Dairy Farm Peshawar, Pakistan from the period 1999 to 2008. Genetic parameters for studied traits were estimated using multiple-trait animal model by DMU Software package with year and season of birth as fixed effects. The effect of year and season of birth was found significant on all the traits under study. Mean Puberty Age (PA), Age at First Calving (AFC) first lactation 305 Days Milk Yield (305 DMY) and Reproductive Efficiency (RE) were 794.32±45.35 days, 1172.27±79.65 days, 3553±423.26 kg and 62.50±3.56%, respectively. Heritability estimates of PA, AFC, RE and first lactation 305 DMY were 0.17, 0.11, 0.12 and 0.22, respectively. Genetic correlation of PA with AFC was highly positive (0.67) whereas, genetic and phenotypic correlation of RE with PA and AFC was moderately negative. Genetic correlations of 305 DMY was highly negative with AFC and RE and moderately negative with PA. In the present study, Holstein outperformed indigenous breeds in terms of performance and genetically inheritable potential under the prevailing subtropical conditions of Pakistan. RE parameter studied is useful indicator for moderately inheritable reproductive traits and should be considered in future studies using large dataset. Interestingly, the genetic parameters of holstein in the present study were in normal range but the production was markedly lower than other studies in the temperate environmental conditions.
Population Analysis of Some Agronomic and Technological Characteristics of Upland Cotton (Gossypium hirsutum L.), Using Diallel Analysis
Muhammad Subhan,Himayat Ullah Khan,Riaz-ud-Din Ahmad
Journal of Biological Sciences , 2001,
Abstract: Significant differences among hybrids and their parents were noted in number of bolls per plant, seeds per boll, and lint percentage (GOT), exposed additive type of gene influence while Vr/Wr graphs indicated over-dominance type of gene action for seed cotton yield per plant. The non-significant deviation of regression line from unit slope indicates the absence of non-allelic interaction in number of bolls per plant, yield of seed cotton, and seeds per boll showing absence of epistasis which provides positive out lines for isolating superior genotypes. The significant deviation from unit slope indicates the presence of epistasis in lint percentage (GOT) which confirmes its less effectiveness from selection point of view.

Genotype X Environment Interaction in Soybeans Grown in Oklahoma (USA) and in NWFP (Pakistan)
F. Subhan,L. H. Edwards
Journal of Biological Sciences , 2001,
Abstract: Fifteen genotypes of group IV and group V soybeans from the Oklahoma Soybean Variety Test were grown from 1991 to 1994 at four Oklahoma (USA) locations and in 1994 four NWFP (Pakistan) locations to investigate Genotype x Environment (GE) interactions and genotypic stability. Significant Genotype x Locations and Genotype x Location x Year (GLY) interactions was observed for seed yield. The top-yielding genotypes at Bixby were Hartwig, OK 885409, HSC 591 and Hutcheson. At Haskell the top-yielding genotypes included Hutcheson, OK 885409 and Manokin. At Chickasha and Goodwell 7 and 9 genotypes were in the top yielding group; respectively. OK 885409 was in the top-yielding group in 1991, 1992 and 1994 at Bixby, in 1991, 1993 and 1994 at Chickasha, and in all four years at Haskell. A significant Genotype x Location (GL) interaction was observed for seed yield when all eight locations (in Pakistan and the USA) were studied in 1994. Only Haskell-Mansehra and Chickasha-Mansehra showed nonsignificant Genotype x Location interactions. Combined regression analysis was also used. Genotypes OK 885409, Hutcheson, HSC 401 and Bay had nonsignificant residual mean squares but only OK 885409 and Hutcheson had b value close to one and a mean yield higher than the grand mean. These genotypes are less responsive to favorable environments, but should perform in a more predictable or stable manner.
Effect of Increasing Levels of Phosphorus and Seed Rate on the Economic Yield of Maize
M. Qasim,Himayatullah,M. Subhan
Journal of Biological Sciences , 2001,
Abstract: Number of cobs per plot, 1000-grain weight and grain yield were significantly effected by various levels of phosphorus and seed rate. Maximum number of cobs per plot (72.58), 1000-grain weight (334.08 g) and grain yield (3154.43 g) were obtained from plots receiving P2O5 @ 200 kg ha -1. Similarly, seed rate @ 60 kg ha -1 gave comparatively higher economic yield. Hence P2O5 @ 200 kg ha -1 and seed rate @ 60 kg ha -1 proved to be the best fertilizer and seed rate among all the treatments.

Manju Mohan, Subhan K. Pathan, Kolli Narendrareddy, Anurag Kandya, Sucheta Pandey
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.29147
Abstract: The rapid expansion of urban areas due to rise in population and economic growth is increasing additional demand on natural resources thereby causing land-use changes especially in megacities. Therefore, serious problems associated with rapid development such as additional infrastructure, informal settlements, environmental pollution, destruction of ecological structure and scarcity of natural resources has been studied carefully using remote sensing and GIS technologies for a rapidly grown megacity namely, Delhi. The present work evaluates the land use/land cover (LULC) changes and urban expansion in Mega city Delhi and highlights the major impact of rapid urbanization and population growth on the land cover changes which needs immediate attention. The results indicate that the city is expanding towards its peripheral region with the conversion of rural regions in to urban expansions. Built-up area of Delhi witnessed an overall increment from 540.7 km² to 791.96 km² or 16.86% of the total city area (1,490 km² ) during the study period 1997 to 2008 which mainly came from agriculture land, waste land, scrub-land, sandy areas and water bodies. The increment in forest cover of 0.5 % is very small when considering the increment in built up category to 17%. Total area of waterbodies has reduced by 52.9% in a ten year period (58.26 km² in 1997 to 27.43 km² in 2008) with shallow waterbodies now having a dismal presence. LULC changes are studied with the urban growth parameters such as population, vehicles, gross state domestic product etc. The results lay emphasis on the concepts of urban planning to be applied such that more consideration is towards the preservation and management of natural land use classes which will increase the quality of life in an urban environment.

Abstract: Pregnancy is uncommon in women with advanced cirrhosis and is associated with an increased risk of complications such as bleeding from esophageal varices, liver failure, and hepatorenal syndrome [1-4]. Maternal deaths have been reported in advanced cirrhosis mainly due to variceal bleeding [4]. Spontaneous abortion and increased risk of premature childbirth or stillbirth have been reported in 15–20% of pregnancies in women with cirrhosis [5]. We are reporting the case of a successful pregnancy outcome of a woman with decompensated cirrhosis, affected by hepatitis B, C and D viruses. To the best of our knowledge this is the first report of pregnancy in a mother who had combined hepatitis B antigenemia, hepatitis delta and hepatitis C infection.A 32 year old mother of two children presented at 16 weeks gestation with abdominal distention and edematous legs. There was no history of hematemesis, melena or altered mental status. Physical examination revealed pallor, spider telangectesia on the arms, palmer erythema and pedal edema. Her abdominal examination showed splenomegaly (to the level of the umbilicus) and moderate ascities. There was no clinical evidence of portosystemic encephalopathy. Her pulmonary, cardiovascular and neurological examinations were unremarkable. Investigations revealed hemoglobin of 8.5 gm/dl with peripheral smear suggestive of microcytic hypochromic anemia, total leukocyte count of 4200/mm3 (63% polymorphs and 32% lymphocytes), platelets 40,000/mm3, total billirubin 2.0 mg/dl, serum glutamic oxaloacetic transaminase 74 (8–32) IU/L, serum glutamic pyruvic transaminase 41 (Normal 3–33) IU/L, GGT of 61 IU/L and alkaline phosphatase 81 (29–132) IU/L, serum albumin 2.3 gm/dl and prothrombin time 15.6 seconds (control 12 seconds). She had normal renal function and electrolytes. Abdominal and pelvic ultrasound revealed a shrunken liver, massive spleenomegaly, dilated portal vein, moderate ascities (fig 1 &2) and a 16 week viable fetus. Ascitic fluid a
