Najma Sultana,M. Saeed Arayne,Hina Shamshad,Agha Zeeshan Mirza,Malik Asia Naz,Beenish Fatima,M. Asif,M. Ahmed Mesaik
Spectroscopy: An International Journal , 2011, DOI: 10.3233/spe-2011-0537
Abstract: Cetirizine second generation H1-receptor antagonist is an acid metabolite of hydroxyzine. Present work was based on six new analogues of cetirizine having nucleophilic substitution reaction synthetic pathway. The reactions were proceeded by replacing the scaffold on the cetirizine moiety using nucleophilic substitution reaction. The structures of analogues were confirmed using UV, IR, 1H NMR and mass spectroscopic techniques. The analogues were tested for the anti-inflammatory activities on cellular immune response. Oxidative burst response of phagocytes after exposure to the analogues was found to exhibit moderate to significant inhibitory activity (23 to <3.1). However, the compounds as MPC and PPC also showed remarkable inhibitory effect on PHA activated T-cells response and may prove to be lead compounds in therapeutic world.

Sameera Hassan, Muhammad Bilal Sarwar, Sajjad Sadique, Bushra Rashid, Beenish Aftab, Bahaeldeen Babiker Mohamed, Tayyab Husnain
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.55075
Abstract:

Salinity is one of the most serious growth limiting factor, therefore, no longer being ignored. Although, cotton is fairly salt tolerant; its sensitivity at crop stand and yield is affected. This study is planned to identify the growth, physiological and molecular parameters in local cotton varieties FDH 171 and FDH 786 under NaCl stress. There was 100% seed germination but hypocotyl length was reduced at increasing level of NaCl. Plant height, fresh and dry biomass were reduced as the plants were subjected to increased stress of NaCl. Stomatal conductance, transpiration and photosynthetic rate and ionic imbalance were found to be reduced under the gradual increase in NaCl stress and affected the plant’s overall physiological processes. PCR product of AtNHX3 has been identified in stressed and non-stressed plants. Thus, the genotypes FDH 171 & FDH 786 were found tolerant to adoption of salt stress and could be used as a source in crop improvement.

S. Muhammad, A. Fatima
Journal of Biosciences and Medicines (JBM) , 2014, DOI: 10.4236/jbm.2014.23006
Abstract: Kola nut is a native stimulant which is commonly chewed in many West African cultures, individually or in a group setting. It is often used ceremonially and to honour guest. Phytochemical analysis and antibacterial screening of red and white Cola nitida (kola nut) extracts were evaluated using qualitative and quantitative method. Thin layer chromatography (TLC) was used to
evaluate the phenolic content. Antibacterial screening was done using agar well diffusion method against odontopathogens; (Lactobacillus sp., Corynebacterium haemolyticum, Proteus vulgans, Bacillus lentus, Streptococcus anginosus and Pseudomonas aeruginosa) obtained from stock cultures. Phytochemical screening revealed the presence of alkaloids, flavonoids, saponin, tannins, glycoside, steroids, volatile oil and balsams. Higher content of alkaloids, saponin and glycoside was obtained in the aqueous extract than the methanol for both red and white kola nut. The results of TLC analysis revealed the presence of quercetin and coumarin in red kola and keamferol and coumarin in white kola respectively. The result of antibacterial activity of red C. nitida showed a zone of inhibition of 18 mm and 23 mm at 60 mg/ml for aqueous extract on Proteus vulgans and
Streptococcus anginosus. Similarly white kola inhibited the growth of S. anginosus at 90 mg/ml with a zone of 18 mm. Methanol extract of red kola inhibited the growth of P. vulgans and S. anginosus at 60 mg/ml with a zone of 16 mm and 20 mm respectively. Acetone and ethyl acetate extracts of both red and white kola nut did not show any activity against the tested organism at all concentrations. The results obtained indicate that C. nitida which posses promising chemotherapeutic and antibacterial potentials respectively that could be useful against odontopathogens. The study may serve as baseline for further studies.

History-Based Backoff Algorithms for Mobile Ad Hoc Networks  [PDF]
Saher Manaseer, Fatima Badwan
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.411004
Abstract: Mobile Ad hoc Network (MANET) is a wireless network consisting of mobile devices (laptops, smart phones, etc.) that move and communicate with each other without the use of any existing network infrastructure or centralized server to avoid collisions which have negative effects on the performance of the network. Access to the shared media is controlled by a Backoff algorithm that is a part of the Media Access Protocol. In this paper, we improve the History Based Probabilistic Backoff (HPPB) algorithm by modifying the increment/decrement behavior of the Contention Window to introduce History Based Increment Backoff (HBIB) algorithm which outperforms HBPB in terms of throughput and end-to-end delay with various numbers of nodes and different traffic loads.

Meherwar Fatima, Maruf Pasha
Journal of Intelligent Learning Systems and Applications (JILSA) , 2017, DOI: 10.4236/jilsa.2017.91001
Abstract: In medical imaging, Computer Aided Diagnosis (CAD) is a rapidly growing dynamic area of research. In recent years, significant attempts are made for the enhancement of computer aided diagnosis applications because errors in medical diagnostic systems can result in seriously misleading medical treatments. Machine learning is important in Computer Aided Diagnosis. After using an easy equation, objects such as organs may not be indicated accurately. So, pattern recognition fundamentally involves learning from examples. In the field of bio-medical, pattern recognition and machine learning promise the improved accuracy of perception and diagnosis of disease. They also promote the objectivity of decision-making process. For the analysis of high-dimensional and multimodal bio-medical data, machine learning offers a worthy approach for making classy and automatic algorithms. This survey paper provides the comparative analysis of different machine learning algorithms for diagnosis of different diseases such as heart disease, diabetes disease, liver disease, dengue disease and hepatitis disease. It brings attention towards the suite of machine learning algorithms and tools that are used for the analysis of diseases and decision-making process accordingly.
