The present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (PGRs) combinations under in vitro conditions. The cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in MS medium containing BA (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and TDZ (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...

Two morphactins and three aminofluorenes initiated the formation of compact tissue nodules in hormone-dependent tobacco callus cultures. These nodules, upon subculture, behaved like partially transformed plant tumors. They grew on cytokinin-free media, while control callus and nonnodule tissue still required an exogenous cytokinin source. The data indicate that substituted fluorenes, including ...

OBJECTIVES This study compared callus formation in distal femur fractures stabilized with locking plates and intramedullary nails to test the hypothesis that locking plates induce less fracture callus than IM nails. DESIGN Retrospective case matched study. SETTING Two orthopaedic trauma centers. PATIENTS 174 distal femur fracture were reviewed to extract cases treated with retrograde IM n...

We compared the growth of trees produced by micropropagation from nodal stem sections or callus tissue of a 20-year-old silver birch (Betula pendula Roth) tree with that of seedlings; growth was monitored for 17 months in pots followed by six years in the field. Micropropagated trees from both nodal stem sections and callus tissue grew at a similar rate to seedling trees and no obvious mutant t...

Follow-up radiographs are important to assess proper alignment and adequate healing of a fracture. The formation of a callus is one characteristic used to follow these features, but the timing and size of its appearance is variable. Therefore, when to expect to see a callus on radiographs requires a general understanding of the fracture healing process and the many variables that can affect cal...

WU, FANG-SHENG, and H. H. MURAKISHI. 1978. Infection and synthesis rate of southern bean mosaic virus in soybean callus cells under selected cultural conditions. Phytopathology 68:1389-1392. Soybean (Glycine max 'Harosoy 63') callus cells grown in with that of Prince bean callus treated identically or with either Eriksson's or Linsmaier and Skoog's media were infected soybean plants grown in th...

This study investigated the localization of critical enzymes involved in arachidonic acid metabolism during the initial and regenerative phases of mouse femur fracture healing. Previous studies found that loss of cyclooxygenase-2 activity impairs fracture healing while loss of 5-lipoxygenase activity accelerates healing. These diametric results show that arachidonic acid metabolism has an essen...

the use of herbal products in the prevention of the growth of pathogens have been widely studied. problems in the treatment of infections caused by resistant strains of fungi are indicator of the need for a more in-detailed study of herbal remedies. artemisia aucheri is used as a medicinal plant with anti-microbial properties, and as an astringent. plant tissue culture is an important technique...
