Papillary thyroid carcinoma is the most common cancer and commonly presents asymptomatically in a patient with cervical node enlargement. The defining characteristic of metastatic papillary its ability to spread through lymphatic system. However, this case details 71-year-old woman who initially complaints back pain leg weakness. Imaging showed an epidural mass pathologic fracture at 10th thoracic vertebrae (T10). A T10 corpectomy tumor excision posterior T8-L1 laminectomy fusion was...
Production and use of doubled haploids (DH) is becoming an essential part maize breeding programs worldwide as DH lines offer several advantages in line development evaluation. One the critical steps production doubling chromosomes vivo-derived so that naturally sterile become reproductively fertile diploids to produce seed. This step artificially labor-intensive costly; hence, optimizing protocols improve success for achieving efficiencies pipelines. Immersion 3-4-day old germinating...
Doubled haploid (DH) technology has become integral to maize breeding programs expedite inbred line development and increase the efficiency of operations. Unlike many other plant species that use in vitro methods, DH production uses a relatively simple efficient vivo induction method. However, it takes two complete crop cycles for generation, one chromosome doubling seed production. Rescuing induced embryos potential reduce time improve identification few (~10%) resulting from an cross rest...
Conventionally, local seed sources are normally believed to perform better than introduced materials. However, studies show possibility of contrary results with many species such as Acacia senegal. The is an economically and ecologically important tree arid semi-arid lands sub-Saharan Africa. It produces gum arabic, used in land reclamation agroforestry production. however underutilized Kenya due lack information on growth performance different sources. Glasshouse provenance trial using...
A total of 150 bacterial strains were isolated from the root nodules Prosopis juliflora growing in soils collected Marigat area Kenya.Soil samples representative colonized zones Tortilis, Grass and used trapping microsymbionts.A physiological plate screening allowed selection 60 which characterized based on morphological, cultural biochemical characteristics.Tolerance to salinity, acid alkaline pH resistance antibiotics studied as phenotypic markers.Morphological characteristics description...
Research on decay profiles of grass detritus in lotic systems has received little attention preceding years. An investigation was conducted in-situ processing coefficients for three dominant forage species grown by farmers along the banks River Nyangores 2013. The objectives study were; (i) to determine Pennisetum purpureum , Panicum coloratum and Chloris gayana (ii) estimate detrital total phosphorus trends during incubation. It hypothesized that no significant differences existed among...
