The Possibility to Use Selected Mixtures of Pgpr Bacteria in Tomato Cultivation
Mixtures of different plant growth-promoting rhizobacteria (PGPR) were used to control soil-borne pathogens of tomato plants. First, their effect was studied in mini-chamber tests against Rhizoctonia damping-off. The best strains and their mixtures were selected for the greenhouse and field experiments conducted in years 2006-2007. The seeds and then the roots of tomato transplants were inoculated with the suspensions of single bacterial strains or with their combinations. In the greenhouse experiments treated plants were grown in the potting medium infested with pathogenic Fusarium oxysporum f. sp. lycopersici, and the effect of bacteria on the population of Fusarium spp. in the rhizosphere was studied. In field experiments the plants were planted into natural infested soil. In both kind of the experiments (greenhouse and field) the impact of the inoculation on plant yield and diseases incidence was evaluated. Although, the results of the preliminary and mini-chamber tests were promising, and the bacteria B125, PT42, SZ141 and their mixtures significantly reduced damping-off of tomato seedlings, in greenhouse and field experiments, in most cases the bacterial treatments failed to improve yield and to protect the plants. Among tested bacterial inoculations only the mixture of the bacteria B125 and PT42 tended to affect positively the growth of the plants and to reduce their infection by soil-borne pathogens. However, bacterial inoculations significantly decreased the density of Fusarium spp. in the rhizosphere of tomato plants.

The Effect of Plant Pruning on the Light Conditions and Vegetative Development of Eggplant (Solanum Melongena L.) in Greenhouse Cultivation
The aim of the present investigations was to find the relations between pruning methods and chosen parameters of vegetative eggplant development in greenhouse conditions. The plant shape modifies the photosynthetically active radiation (PAR) conditions in the plant profile. Independence between different pruning methods and vegetative plant development particularly leaves characteristics as well as pigments and photosynthesis products content in leaves was stated. The investigations were carried out in 1999-2001 in the experimental greenhouse of Agricultural University in Kraków, Poland. Eggplant of Tania F1 hybrid was used in the early spring-summer production in a heated greenhouse. The following pruning systems were applied: pruning to one shoot with leaving on every node 2 fruit sets and 1, 2 or 3 leaves, and pruning to two shoots with leaving on every node 1 fruit set and 1, 2 or 3 leaves. With the introduction of a greater number of leaves and fruit sets on eggplant shoots irradiation in plant profile was reduced. The value of leaf area index (LAI) depended on the way of pruning. Chemical composition of leaves was slightly dependent on the method of pruning only in the case of assimilation products, i.e. reducing sugar and starch. Improvement of photosynthesis efficiency of intensively pruned eggplants was achieved by the increase of single leaf area and thickness of leaf mesophyll tissues without the increase of the level of assimilative pigments per plant mass unit.

The Effect of Different Soil and Plant Cultivation Methods on Yield and Chemical Composition of Scorzonera Roots
In 1997-2000, field experiments were carried out on a grey-brown podzolic soil. The experimental plant was scorzonera (Scorzonera hispanica L.) cv. Einjährige Riesen. The aim of the experiments was to assess the yields of scorzonera roots in different soil and plant cultivation systems: ridge and flat cultivation, reduced soil tillage prior to sowing (shallow tillage), and the application of cover crops (Sinapis alba L., Vicia sativa L., Phacelia tanacetifolia B., Avena sativa L.) in conservation tillage and no-tillage systems. Reduced spring tillage did not have a negative effect on the yields of scorzonera roots. Cultivation of plants on ridges had a positive effect on the total and marketable yields of roots in comparison with flat soil cultivation. Mulching with cover crops had a significant influence on the increase in the marketable yield of roots. No-tillage cultivation did not have a negative effect on the total and marketable yields of roots. Reduction in spring tillage prior to sowing, soil mulching, and no-tillage cultivation had no negative effects on the inulin content of scorzonera roots. Among the investigated cover crops, Sinapis alba L. was the most beneficial plant for increasing the inulin content of roots. Cultivation of plants on ridges and flat soil, and reduction in spring pre-sowing tillage did not have a significant effect on the protein content of roots. Irrespective of the soil cultivation methods, a significantly higher protein content was found in the roots harvested from the plots mulched with Vicia sativa L. The various plant cultivation conditions exerted a considerable influence on nutrient uptake. Roots of the plants cultivated on ridges contained higher amounts of P, K, and Ca. Soil mulching created better conditions for nutrient absorption. A significant effect of Sinapis alba L. in increasing the P and K content of roots was also observed.

Effect of Long-Term Organic and Mineral Fertilization on the Yield and Quality of Red Beet (Beta vulgaris L.)
In 2003-2004, an experiment was carried out with two cultivars of red beet using the experimental plots of a long-term static fertilization experiment that was begun in 1922 in the Experimental Field of the Institute of Vegetable Crops in Skierniewice. Under assessment was the response of red beet plants to longterm organic, mineral, and organic-mineral fertilization applied at different rates. The highest marketable yield, of all the fertilization combinations, was obtained in each year of the experiment from the each year treatment with manure alone at 60 t·ha-1. However, the level of red pigments in beet roots from this treatment was low, while that of yellow pigments, and also of nitrates, was high. Fertilization with manure at 60 t·ha-1 in combination with mineral nitrogen fertilization at 60 kg N·ha-1 resulted in a lower marketable yield compared to the treatment with manure only. The roots from the combined treatment, like those from the treatment with manure alone at 60 t·ha-1, had a low ratio of betanine to vulgaxanthine, and the highest nitrate content of all the fertilization combinations. At lower levels of fertilization with manure (20 and 40 t·ha-1), the additional fertilization with mineral nitrogen increased the marketable yield of red beet roots, but it reduced betanine content in 2003, and increased the level of nitrates in both years, in comparison with the corresponding treatments with manure only. Relatively high marketable yields of well-coloured roots with a high betanine content and a low vulgaxanthine content, and a low level of nitrates, were obtained from the treatment with mineral fertilizers applied at the lowest rates (N - 60, P2O5 - 30, K2O - 70 kg·ha-1). However, as the application rates of these fertilizers increased, the marketable yield of beet roots and their betanine content decreased. At the same time, the level of nitrates in the roots of both cultivars increased. The lowest marketable yields, but of well-coloured beet roots with a low nitrate content were obtained from the zero-fertilization control plots and from the treatment with manure alone at 20 t·ha-1.

Quality Characteristics of Fresh Plant Sprouts and After Their Short-term Storage
Sensory characteristics, carotenoids content and antioxidant activity of sprouted seeds of eight plant species were investigated. Seeds of lentil, broccoli, clover, amaranth, wheat, radish, pea, and alfalfa were germinated for 3 days in the dark, at the temperature of 25°C and then sprouted seeds were stored for the next 2 days in a refrigerator, in the dark, at the temperature of 4-5°C. Sensory quality was evaluated in the expert panel, with the quantitative descriptive analysis method (QDA), using 15 sensory attributes, concerning odour, texture and flavour. Radish, alfalfa and lentil sprouts showed the highest overall sensory quality. Sensory attributes of sprouts were strongly differentiated among the species and the biggest differences were found for spicy flavour and sweet taste attributes. 2-day storage of sprouts affected some taste/flavour descriptors. Total carotenoids and β-carotene content were the highest in broccoli and radish sprouts. During the storage of sprouts carotenoids content decreased. Antioxidant activity was differentiated between species, and both radish and broccoli sprouts showed the highest antioxidant activity.

Disturbances in Vessel Traffic Stream Due to Fairway RegulationsAll regulations disturb the randomness of the vessel traffic stream. In the present paper the effect of the following regulations on the vessel traffic stream has been analysed: the order to maintain minimum distance between successive vessels, speed limit, overtaking ban, passing ban. These regulations disturb the Poissonian nature of the stream of reports. Using the method of random variables convolution the density function of probability was determined of the disturbed vessels' stream of reporting for particular factors controlling traffic on the fairway.

Authors: Wang Michael Y. , Ludwig Steven C. , Anderson D. Greg , Mummaneni Praveen V. 
Published: August 2008

Minimally invasive spinal instrumentation techniques have evolved tremendously over the past decade. Although there have been numerous reports of lumbar instrumentation performed via a percutaneous or minimal incisional route, to date there have been no reports of minimally invasive iliac screw placement.
A method was developed for accurate placement of minimally invasive iliac screw placement based on a modification of currently available percutaneous lumbar instrumentation techniques. The method involves fluoroscopically guided insertion of a cannula-based screw system, and this technique was successful applied to treat an L-5 burst fracture with L-4 to iliac spinal stabilization via a minimally invasive approach.
This report demonstrates the feasibility of percutaneous iliac screw instrumentation. However, future studies will be needed to validate the safety and efficacy of this approach.
Review of spinal radiosurgery: a minimally invasive approach for the treatment of spinal and paraspinal metastases
Authors: Sheehan Jason P. , Jagannathan Jay 
Published: August 2008

Intracranial radiosurgery has been proved effective for the treatment of brain metastasis. The treatment of paraspinal and spinal metastasis with spinal radiosurgery represents a natural extension of the principles of intracranial radiosurgery. However, spinal radiosurgery is a far more complicated process than intracranial radiosurgery. Larger treatment volumes, numerous organs at risk, and the inability to utilize rigid, frame-based immobilization all contribute to the substantially more complex process of spinal radiosurgery.
Beyond the convenience of a shorter duration of treatment for the patient, spinal radiosurgery affords a greater biological equivalent dose to a metastatic lesion than conventional radiotherapy fractionation schemes. This appears to translate into a high rate of tumor control and fast pain relief for patients. The minimally invasive nature of this approach is consistent with trends in open spinal surgery and helps to maintain or improve a patient's quality of life. Spinal radiosurgery has expanded the neurosurgical treatment armamentarium for patients with spinal and paraspinal metastasis.

Published: August 2008

Object
Minimally invasive lumbar discectomy is a refinement of the standard open microsurgical discectomy technique. Proponents of the minimally invasive technique suggest that it improves patient outcome, shortens hospital stay, and decreases hospital costs. Despite these claims there is little support in the literature to justify the adoption of minimally invasive discectomy over standard open microsurgical discectomy. In the present study, the authors address some of these issues by comparing the short-term outcomes in patients who underwent first time, single-level lumbar discectomy at L3–4, L4–5, or L5–S1 using either a minimally invasive percutaneous, muscle splitting approach or a standard, open, muscle-stripping microsurgical approach.

Methods
A retrospective chart review of 172 patients who had undergone a first-time, single-level lumbar discectomy at either L3–4, L4–5, or L5–S1 was performed. Perioperative results were assessed by comparing the following parameters between patients who had undergone minimally invasive discectomy and those who received standard open microsurgical discectomy: length of stay, operative time, estimated blood loss, rate of cerebrospinal fluid leak, post-anesthesia care unit narcotic use, need for a physical therapy consultation, and need for admission to the hospital.

Results
Forty-nine patients underwent minimally invasive discectomy, and 123 patients underwent open microsurgical discectomy. At baseline the groups did differ significantly with respect to age, but did not differ with respect to height, weight, sex, body mass index, level of radiculopathy, side of radiculopathy, insurance status, or type of preoperative analgesic use. No statistically significant differences were identified in operative time, rate of cerebrospinal fluid leak, or need for a physical therapy consultation. Statistically significant differences were identified in length of stay, estimated blood loss, postanesthesia care unit narcotic use, and need for admission to the hospital.

Conclusions
In this retrospective study, patients who underwent minimally invasive discectomy were found to have similiar perioperative results as those who underwent open microsurgical discectomy. The differences, although statistically significant, are of modest clinical significance.
The Mini-Open transpedicular thoracic discectomy: surgical technique and assessment
Authors: Chi John H. , Dhall Sanjay S. , Kanter Adam S. , Mummaneni Praveen V. 
Published: August 2008

Object
Thoracic disc herniations can be surgically treated with a number of different techniques and approaches. However, surgical outcomes comparing the various techniques are rarely reported in the literature. The authors describe a minimally invasive technique to approach thoracic disc herniations via a transpedicular route with the use of tubular retractors and microscope visualization. This technique provides a safe method to identify the thoracic disc space and perform a decompression with minimal paraspinal soft tissue disruption. The authors compare the results of this approach with clinical results after open transpedicular discectomy.

Methods
The authors performed a retrospective cohort study comparing results in 11 patients with symptomatic thoracic disc herniations treated with either open posterolateral (4 patients) or mini-open transpedicular discectomy (7 patients). Hospital stay, blood loss, modified Prolo score, and Frankel score were used as outcome variables.

Results
Patients who underwent mini-open transpedicular discectomy had less blood loss and showed greater improvement in modified Prolo scores (p = 0.024 and p = 0.05, respectively) than those who underwent open transpedicular discectomy at the time of early follow-up within 1 year of surgery. However, at an average of 18 months of follow-up, the Prolo score difference between the 2 surgical groups was not statistically significant. There were no major or minor surgical complications in the patients who received the minimally invasive technique.

Conclusions
The mini-open transpedicular discectomy for thoracic disc herniations results in better modified Prolo scores at early postoperative intervals and less blood loss during surgery than open posterolateral discectomy. The authors' technique is described in detail and an intraoperative video is provided.
Minimally invasive thoracoscopic approach for anterior decompression and stabilization of metastatic spine disease
Authors: Kan Peter , Schmidt Meic H. 
Published: August 2008

Object
The choices available in the management of metastatic spine disease are complex, and the role of surgical therapy is increasing. Recent studies have indicated that patients treated with direct surgical decompression and stabilization before radiation have better functional outcomes than those treated with radiation alone. The most common anterior surgical approach for direct spinal cord decompression and stabilization in the thoracic spine is open thoracotomy; however, thoracotomy for spinal access is associated with morbidity that can be avoided with minimally invasive techniques like thoracoscopy.

Methods
A minimally invasive thoracoscopic approach was used for the surgical treatment of thoracic and thoracolumbar metastatic spinal cord compression. This technique allows ventral decompression via corpectomy, inter-body reconstruction with expandable cages, and stabilization with an anterolateral plating system designed specifically for minimally invasive implantation. This technique was performed in 5 patients with metastatic disease of the thoracic spine, including the thoracolumbar junction.

Results
All patients had improvement in preoperative symptoms and neurological deficits. No complications occurred in this small series.

Conclusions
The minimally invasive thoracoscopic approach can be applied to the treatment of thoracic and thoracolumbar metastatic spine disease in an effort to reduce access morbidity. Preliminary results have indicated that adequate decompression, reconstruction, and stabilization can be achieved with this technique.
