Modification of the micro tissue culture technique, including incubation under increased CO(2), resulted in prolongation of the viability of the cells. As a consequence, satisfactory titrations of poliovirus and of poliovirus antiserum have been achieved by the micro method. The technique offers a number of advantages over conventional methods.
Human pe~odont~l ligamen~ from rapidly resorbing pzqmary teeth which also exhibited periapical radiolucency on radiograph demonstrated co]]agenolytic activity when incubated on collagen gels. This activity was direc~ly proportional ~o the size of the explant and length of time of incubation.
Quality control ranges were developed for broth microdilution testing of Campylobacter jejuni ATCC 33560 against 14 antimicrobials. Cation-adjusted Mueller-Hinton broth containing 2.5% laked horse blood was the preferred medium, with incubation in a microaerobic atmosphere of 10% CO(2), 5% O(2), and 85% N(2) at 36 degrees C for 48 h or 42 degrees C for 24 h.
Antibodies were compared for use in the spin-amplified shell vial method for rapid cytomegalovirus detection. Commercial antibodies by Du Pont Co., Whittaker M.A. Bioproducts, Bartels Immunodiagnostic, Virostat, and Serono Diagnostics were compared at incubation times of 16 to 48 h on 22 patient specimens. Only the Du Pont antibody showed 100% sensitivity and specificity and no nonspecific reac...
Mitochondrial redox imbalance has been implicated in mechanisms of aging, various degenerative diseases and drug-induced toxicity. Statins are safe and well-tolerated therapeutic drugs that occasionally induce myotoxicity such as myopathy and rhabdomyolysis. Previous studies indicate that myotoxicity caused by statins may be linked to impairment of mitochondrial functions. Here, we report that ...
Acidification and metal mobility may present challenges in soil receiving paper mill biosolids (PB). Co-applying biochar PB could help prevent these issues, but its effect must be assessed. The objective of this 224 d incubation study was to evaluate the amending two acidic soils, a clay sandy loam, with types varying pH (PB1, = 7.80; PB2, 4.51) co-applied three rates (0%, 2.5%, 5% w/w) pine (P...
The aim of this study was to produce sugarcane plantlets from cell suspension culture and study its genetic fidelity using molecular markers. The study was carried out using sugarcane varieties Co 86032 and Q117. Callus cultures of both the varieties were optimized using six different callus induction media. After screening the growth response of callus on six different callus induction media, ...
L-asparaginase has lots of medical and industrial applications. Ever since L-asparaginase anti-tumor activity was first demonstrated, its production using microbial systems has attracted considerable attention owing to their cost-effective and eco-friendly nature. The aim of this study is to obtain L-asparaginase producing bacteria and determining the enzyme activity. Samples were picked up fro...
Actinobaculum was isolated from urine only after prolonged incubation in 5% CO(2) after discrepancy between urine Gram stain and initial culture results was observed. Additional patients were diagnosed using this method. The prevalence of Actinobaculum species in urinary tract infections is underestimated since it is not isolated by routine urine culture procedures.
Elevated atmospheric CO(2) concentrations and warming may affect the quality of litters of forest plants and their subsequent decomposition in ecosystems, thereby potentially affecting the global carbon cycle. However, few data on root tissues are available to test this feedback to the atmosphere. In this study, we used fine (diameter < or = 2 mm) and small (2-10 mm) roots of Douglas-fir (Pseud...
