OBJECTIVE Thrombocytopenia in dengue fever is a common and serious complication. However, no specific treatment is available for dengue fever induced thrombocytopenia. In few countries (Pakistan, Malaysia, Sri Lanka and other Asian countries) the leaf extract of Carica papaya has been effectively used for thrombocytopenia. So, the study is planned to access effect of Carica papaya leaf extract ...

The amount of conspicuous canopy dieback in all central Westland southern rata-kamahi forests east of the Alpine Fault, between 500 m altitude and treeline, was assessed and mapped from aerial photographs taken in 1984-85 and verified by aerial reconnaissance of selected areas in 1988. At least 20% of all canopy trees, predominantly southern rata (Metrosideros umbellata) and Hall's totara (Podo...

Papaya (Carica papaya L.) pulp tissue disks in an incubation medium composed of 0.4 m sucrose evolve ethylene at an optimum pH of 5.25 at 30 C. Disks of young preclimacteric fruit evolve the gas linearly with fruit age until fruit age reaches 4 months. Disks from 5-month-old postclimacteric fruit produce approximately 5-fold more ethylene than disks from 4-month-old fruit. Ethylene evolution by...

A total of seven fungi were identified from the surface of fully matured papaya fruits cv. ‘Sekaki’ collected form two different fields namely University Agriculture Park, UPM and MARDI, Selangor and a fruit exporter [Seng Chew Hup Kee (M) Sdn Bhd, Kajang, Selangor, Malaysia]. They were identified as Botryodiplodia theobromae, Colletotrichum capsici, C. gloeosporioides, Fusarium sp., Phomopsis ...

Carica papaya (papaya) is an economically important tropical fruit. Molecular marker-assisted selection is an inexpensive and reliable tool that has been widely used to improve fruit quality traits and resistance against diseases. In the present study we report the development and validation of an atlas of papaya simple sequence repeat (SSR) markers. We integrated gene predictions and functiona...

A preliminary survey of genetic diversity among 34 commercially popular Carica papaya cultivars from India and abroad, 6 accessions of Vasconcellea species and 1 accession of Jacaratia spinosa, was done using 20 simple sequence repeat (SSR) markers. The SSR profiles were used to find out total number of alleles, null and rare alleles, Polymorphism Information Content (PIC) values and to calcula...

In the United States, the Papaya ringspot virus was first reported from papaya in Florida in 1949. Here, we determined the first complete genome sequence (10,302 nucleotides) of a Papaya ringspot virus-W isolate, which was collected from a commercial field of gourd in Tulsa, OK.

Protection against diabetic nephropathy (DN) is one of the main targets in diabetes treatment and present study evaluates the nephroprotective effect of Carica papaya L. in streptozotocin (STZ) induced diabetic rats. DN rats were treated with 1.5 and 2.5 gm/dl C. papaya leaf extract for 6 weeks to determine its nephroprotective effect with different parameters. Pimagedine (1 ml/mg) served as a ...

Progressive diebacks of outer canopy branchlets of Ceanothus crassifolius were repeatedly observed after rainless periods up to 9 mo in duration in the Santa Monica Mountains of southern California. Mean xylem pressures of branchlets near the end of drought were as low as -11.2 MPa (N = 22) with a mean of about 60 dead branchlets per shrub. Inoculation (N = 15) with three species of fungi previ...
