Lumbar Fixation Using the Cortical Bone Trajectory Fixation: A Single Surgeon's Experience With 3-Year Follow-up.

Background: Pedicle screw fixation with a cortical bone trajectory (CBT) has emerged as an effective alternative to traditional techniques of lumbar fusion, especially in osteoporotic patients. The proposed benefits of CBT screws include a stronger grip in the elderly and osteoporotic population and low surgical morbidity. We present a prospective study with a 3-yr follow-up of 80 patients operated on by the same surgeon.

Biogenic Silver Nanoparticles for Trace Colorimetric Sensing of Enzyme Disrupter Fungicide Vinclozolin.

We report a novel, simple, efficient, and green protocol for biogenic synthesis of silver nanoparticles (AgNPs) in aqueous solution using clove () extract as a reducing and protecting agent. Ultraviolet-visible (UV-Vis) spectroscopy was employed to monitor the localized surface plasmon resonance (LSPR) band of clove extract-derived AgNPs prepared under various conditions. Fourier-transform infrared (FTIR) spectroscopy analysis provided information about the surface interaction of the clove extract with the AgNPs.

Pineal cyst surveillance in adults - a review of 10 years' experience.

Pineal cysts are common benign incidental findings in adults. There are no commonly accepted criteria for follow up or indications for intervention. We looked at our outcomes for this condition to explore their natural history and review our surveillance criteria.

Management of elderly patients with glioblastoma-multiforme-a systematic review.

The management of elderly patients with glioblastoma-multiforme (GBM) remains poorly defined with many experts in the past advocating best supportive care, in view of limited evidence on efficacy of more aggressive treatment protocols. There is randomised evidence (NORDIC and NA-O8 studies) to support the use of surgery followed by adjuvant monotherapy with either radiotherapy (RT) using hypofractionated regimes (e.g.

Cytophysiological studies on the effects of amphenone 'B' and dexamethasone on the pars distalis and interrenal gland of Rana cyanophlyctis (Schn.).

Amphenone 'B' treatment resulted in the hypertrophy and degranulation of the B3 cells of the pars distalis and stimulation of interrenal cells, whereas administration of dexamethasone caused regression of B3 and interrenal cells. Following 15-day cessation of amphenone or dexamethasone treatment, there was no recovery in the B3 or the interrenal cells. The results suggest that B3 cells are the probable source of ACTH and there exists a relationship between the pituitary and interrenal gland of the frog, R.

Effect of NaCl and KCl salts on the cytomorphology of pars distalis of the frog Rana cyanophlyctis (Schneider).

The effect of salts on the pars distalis of R. cyanophlyctis was studied by placing them in sodium chloride, potassium chloride (0.5%), distilled water and tapwater (control) for 15 days.
