Akhtar, Khalid P.,Khan, Azeem I.,Hussain, M.,Khan, M.S.I. The Korean Society of Plant Pathology 2002 Plant Pathology Journal Vol.18 No.4

Four newly developed cotton mutants (M-111, M-7662, M-358 and M-218) were compared for their resistance against Cotton leaf curl virus(CLCuV) together with commercial resistant (CIM-443, CIM-482, CIM-473, FH-900 and FH-901) and susceptible (5-12) varieties by artificial inoculation through grafting and under natural field conditions. Infectivity and success of grafting were 100% in all cases. None of the grafted plants were found immune or asymptomatic. All the grafted mutants and most of their single plant progeny rows (SPPRs) showed highly resistant responses as the symptoms displayed by these mutants were milder than the commercial cultivars. Grafted mutants also had delayed disease reactions as they took more time (25-30 days) to produce disease symptoms, as compared with resistant commercial varieties that produced disease 18-22 days after inoculation. Growth of the grafted SPPRs of tested mutants was normal, which is an indication that there will be no production losses. Observations under natural infestation of whitefly showed that two SPPRs of M-ll/CE and M-7662-1/2 and one resistant variety CIM-443 exhibited slight incidence of disease, while one SPPR of M-l1/59 and S-12 were moderately susceptible and highly susceptible with 21% and 97.l% disease incidence, respectively. This study also showed that plants displaying more disease symptoms through grafting were easily infected under natural conditions. These results suggest that preference should be given to those plants that exhibited highly resistant responses after artificial inoculation.

Ahmed, Qamar U.,Zaidi, S.M.K.R.,Kaleem, M.,Khan, N.U.,Singhal, K.C. Kyung Hee Oriental Medicine Research Center 2006 Oriental pharmacy and experimental medicine Vol.6 No.2

The effect of aqueous and alcoholic extracts of the fruit, leaf and stem of Melia azedarach Linn. (Meliaceae) on the spontaneous movements of both the whole worm and the nerve-muscle (n.m.) preparation of Setaria (S.) cervi and on the survival of microfilariae in vitro was studied. Alcoholic extracts of fruit, leaf and stem caused inhibition of the spontaneous movements of the whole worm and the n.m. preparation of S. cervi, while only aqueous extract of fruit caused inhibition of the spontaneous movements of the whole worm and the n.m. preparation of S. cervi. The initial stimulatory effect was not observed by the aqueous and alcoholic extracts of fruit on n.m. preparation. The concentrations required to inhibit the movements of the whole worm and n.m. preparation for alcoholic extracts of fruit, leaf and stem were 250, $40\;{\mu}g/ml$; 280, $40\;{\mu}g/ml$ and 270, $25\;{\mu}g/ml$ respectively, whereas an aqueous extract of fruit caused inhibition of whole worm and n.m. preparation at $200\;{\mu}g/ml$ and $40\;{\mu}g/ml$ respectively. Alcoholic extracts of the fruit, leaf and stem and aqueous extract of the fruit of M. azedarach caused concentration related inhibition on the survival of microfilariae (m.f.) of S. cervi. The $LC_{50}$ and $LC_{90}$ as observed after 6 h were found to be 5, 15, 10, 20 ng/ml and 10, 25, 20 and 35 ng/ml, respectively. This work was conducted in view of the exploration of potential antifilarial herbal drug.

Khan, M. Ajmal,Sarwar, Muhammad,Nisa, M.,Khan, M.S.,Bhatti, S.A.,Iqbal, Z.,Lee, W.S.,Lee, H.J.,Kim, H.S.,Ki, K.S. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.5

Thirty early lactating Nili-Ravi buffaloes, six animals in each group, were used in a completely randomized design to examine the feeding value of 4% urea treated wheat straw (UTWS) ensiled with 6% or without acidified molasses. Five experimental diets were formulated. The control ration was balanced to contain 30% DM from UTWS ensiled without acidified molasses. The other four diets were formulated to have 30, 40, 50 and 60% DM from UTWS ensiled with 6% acidified molasses, respectively. Dry matter and neutral detergent fiber (NDF) intakes were higher in buffaloes fed diets containing UTWS ensiled with acidified molasses compared with those fed a diet containing UTWS ensiled without acidified molasses. Intake of DM was not significantly different in buffaloes fed diets containing varying levels of UTWS ensiled with acidified molasses. A similar trend was observed for crude protein (CP) intake. Apparent DM and NDF digestibilities were significantly higher in buffaloes fed diets containing UTWS ensiled with acidified molasses compared with those fed UTWS ensiled without acidified molasses. However, differences in DM and NDF digestibilities were non-significant across buffaloes fed diets containing varying levels of UTWS ensiled with acidified molasses. Milk yield (4% fat corrected) was significantly higher in buffaloes fed diets containing UTWS ensiled with acidified molasses than those fed a diet containing UTWS ensiled without acidified molasses. Milk yield was similar in buffaloes fed varying level of UTWS ensiled with acidified molasses. Milk CP, true protein, solid-not-fat and total solids were similar in buffaloes fed UTWS ensiled with or without acidified molasses. The UTWS ensiled with 6% acidified molasses can be included at up to 60% DM of lactating buffalo rations without any ill effect on productivity.

EXISTENCE OF THE SOLUTION OF COUNTABLY INFINITE SYSTEM OF DIFFERENTIAL EQUATIONS IN SEQUENCE SPACES m^p(𝜙) AND n^p(𝜙) WITH THE HELP OF MEASURE OF NON-COMPACTNESS

KHAN, MOHD SHOAIB,UDDIN, IZHAR,LOHANI, Q.M. DANISH The Korean Society for Computational and Applied M 2019 Journal of applied mathematics & informatics Vol.37 No.5

The Banach spaces $m^p(\phi)$ and $n^p(\phi)$ are very important sequence spaces related to $l_p$, which were defined to fill the gaps between $l_p(1{\leq}p{\leq}{\infty})$. In this paper, we investigated the solubility of the infinite system of differential equations in $m^p(\phi)$ and $n^p(\phi)$ by proving related theorems. Moreover, one example has been included for the justification of the claim of this paper.

Effects of Various Mechanical and Chemical Treatments of Rapeseed Meal on the Performance of Broilers

Khan, M.Z.,Mahmood, S.,Sarwar, M.,Nisa, M.,Gulzar, F. Asian Australasian Association of Animal Productio 1998 Animal Bioscience Vol.11 No.6

One hundred and eighty, 1-day old broiler chicks, randomly divided into 15 replicates of 10 brids each were employed to six treatment rations (A, B, C, D, E and F). Rapeseed meal (RSM) with or without treatment was incorporated in the rations at 20 percent level in lieu of soybean meal. The birds in group A were fed soybean based ration and those in group B, C, D, E and F were given ration containing untreated, solvent extracted, water treated, autoclaved and ferrous sulphate treated RSM, respectively. Presence of RSM in the rations whether untreated or treated, significantly reduced weight gain and feed consumption of the birds compared with those of control group but efficiency of feed utilization, dressed weight, dressing percentage and weights of internal organs amongst the groups remained unaffected. The size of thyroid galnds of the broilers using the meal was significantly larger than those having ration without RSM. The only exception was that the birds having solvent extracted meal had similar thyroid gland relative weight as those of control group indicating reduced antinutritional effect of isothiocyanates content due to solvent extraction of the meal.

Chemical Composition, In situ Digestion Kinetics and Feeding Value of Oat Grass (Avena sativa) Ensiled with Molasses for Nili-Ravi Buffaloes

Khan, Muhammad Ajmal,Sarwar, M.,Nisa, M.,Iqbal, Z.,Khan, M.S.,Lee, W.S.,Lee, H.J.,Kim, H.S. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.8

This study examined the effect of cane molasses and fermentation time on chemical composition and characteristics of oat grass silage (OGS) and its in situ digestion kinetics, intake, digestibility, milk yield and composition in buffaloes (Bubalus bubalis). Oat grass (OG) harvested at 50-days of age was ensiled in laboratory silos with cane molasses at the rate of 0, 2, 4 and 6% of OG dry matter (DM) for 30, 35 and 40 days. Silage pH was decreased while lactic acid content increased with increasing level of cane molasses and fermentation time. Dry matter (DM), crude protein (CP) and true protein (TP) content of OGS were (p<0.05) significantly higher with higher cane molasses levels. However, they were not affected by the fermentation time. Similar trends were observed for neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, acid detergent lignin and ash content of OGS. The OG ensiled for 30-days with 2% molasses was screened from laboratory study and used to determine comparative in situ DM and NDF digestion kinetics of OG and its silage. In situ DM and NDF digestibilities of OG were significantly (p<0.05) higher than OGS. Ruminal DM and NDF lag time, rate and extent of digestion of OG and its silage were similar. Two experimental diets of OG and OGS were formulated using 75:25 forage to concentrate ratio on a DM basis. Dry matter and CP intakes were similar in lactating buffaloes fed either OG- or OGS-based diets. However, NDF intake was higher in buffaloes fed the OG-compared with OGS-based diet. Apparent DM, CP and NDF digestibilities were similar in lactating buffaloes fed either OG- or OGS-based diets. Milk yield (4% FCM) was similar in buffaloes fed either OG-(10.3 kg/d) or OGS-(9.95 kg/d) based diets. Milk fat, total solids and true protein content were higher with OG compared with the OGS diet. Solids not fat and CP content were similar in milk of buffalo fed either OG or OGS. The results of this study indicate that OG ensiled with 2% molasses could safely replace 75% DM of green oat fodder in the diets of lactating buffaloes without negatively affecting intake, digestibility, milk yield and composition.

Effect of antidiarrhoeal formulation on acute experimental diarrhoea in rats

Khan, M. Aleem,Khan, Naeem A.,Qasmi, Iqbal A.,Ahmad, Ghufran,Zafar, Shadab Kyung Hee Oriental Medicine Research Center 2005 Oriental pharmacy and experimental medicine Vol.5 No.2

Aqueous extract of antidiarrhoeal formulation (ADF) containing Holarrhena antidysentrica, Aegle marmelos and Punica granatum was investigated for antidiarrhoeal activity against charcoal-induced gut transit, serotonin-induced diarrhoea and $PGE_2-induced$ small intestine enteropooling in rats. The control, standard and test groups of experimental animals were administered with normal saline (p.o.), diphenoxylate hydrochloride (5 mg/kg, p.o.) and ADF (250 mg and 500 mg/kg, p.o.) respectively except the control group of $PGE_2-induced$ small intestine enteropooling which received only 5% ethanol in normal saline (i.p.). Charcoal (10 ml/kg, p.o.) and serotonin $(600\;{\mu}g/kg,\;i.p.)$ were administered after 30 min, while $PGE_2\;(100\;{\mu}g/kg,\;p.o.)$ was administered immediately afterwards. The distance traveled by charcoal in small intestine was measured after 15 and 30 min of charcoal administration, diarrhoea was observed every 30 min for six hour after serotonin administration and the volume of intestinal fluid was measured after 30 min of $PGE_2$ administration. Oral administration of ADF significantly inhibited the frequency of defaecation and decreased the propulsion of charcoal meal through the gastrointestinal tract, reduced the wetness of faecal dropping in serotonin-induced diarrhoea and also reduced the $PGE_2-induced$small intestine enteropooling. ADF may have potential to reduce the diarrhoea in rats.

Transient Multipath routing protocol for low power and lossy networks

( M Ali Lodhi ),( Abdul Rehman ),( Meer M Khan ),( Muhammad Asfand-e-yar ),( Faisal Bashir Hussain ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.4

RPL routing protocol for low-power and lossy networks is an Internet Engineering Task Force (IETF) recommended IPv6 based protocol for routing over Low power Lossy Networks (LLNs). RPL is proposed for networks with characteristics like small packet size, low bandwidth, low data rate, lossy wireless links and low power. RPL is a proactive routing protocol that creates a Directed Acyclic Graph (DAG) of the network topology. RPL is increasingly used for Internet of Things (IoT) which comprises of heterogeneous networks and applications. RPL proposes a single path routing strategy. The forwarding technique of RPL does not support multiple paths between source and destination. Multipath routing is an important strategy used in both sensor and ad-hoc network for performance enhancement. Multipath routing is also used to achieve multi-fold objectives including higher reliability, increase in throughput, fault tolerance, congestion mitigation and hole avoidance. In this paper, M-RPL (Multi-path extension of RPL) is proposed, which aims to provide temporary multiple paths during congestion over a single routing path. Congestion is primarily detected using buffer size and packet delivery ratio at forwarding nodes. Congestion is mitigated by creating partially disjoint multiple paths and by avoiding forwarding of packets through the congested node. Detailed simulation analysis of M-RPL against RPL in both grid and random topologies shows that M-RPL successfully mitigates congestion and it enhances overall network throughput.

Momordica charantia and Allium sativum : Broad Spectrum Antibacterial Activity

Khan, M.R.,Omoloso, A.D. The Korean Society of Pharmacognosy 1998 생약학회지 Vol.29 No.3

In the Asian sub-continent Momordica charantia and Allium sativum are extensively used as food and are popular in herbal medicine. The two were screened against 15 pathogens and both exhibited broard spectrum antimicrobial activity. As compared to the standard antibiotics, M. charantia demonstrated broader and higher level of activity against most of the organisms. On the other hand A. sativum showed comparable activity to the standard antibiotics. Both M. Charantia and A. sativum are proposed as non toxic, safe, broad spectrum antibacterial agents.
