Benchmarking Bulb Yield, Medicinal Sulfur Compounds, and Mineral Nutrition of Garlic Varieties.

Garlic is widely cultivated for both its culinary and medicinal properties. Bulb yield, organosulfur compounds, and plant mineral nutrition of 32 garlic varieties were characterized. Across genotypes, there was large variability in bulb weight and alliin and allicin concentrations.

Sulfur Nutrition Affects Garlic Bulb Yield and Allicin Concentration.

Improving bulb yield and allicin content of garlic is important in meeting fresh and pharmaceutical market demands. Garlic plants have a high demand for sulfur (S) since allicin contains S atoms. Two experiments were conducted to identify the effect of S application rate on garlic yield and quality.

Effects of distraction on magnetoencephalographic responses ascending through C-fibers in humans.

Objective: Using magnetoencephalography (MEG), we evaluated the cerebral regions relating to second pain perception ascending through C-fibers and investigated the effect of distraction on each region.

Methods: Thirteen normal subjects participated in this study. CO2 laser pulses were delivered to the dorsum of the left hand to selectively activate C-fibers.

Pain processing within the primary somatosensory cortex in humans.

To investigate the processing of noxious stimuli within the primary somatosensory cortex (SI), we recorded magnetoencephalography following noxious epidermal electrical stimulation (ES) and innocuous transcutaneous electrical stimulation (TS) applied to the dorsum of the left hand. TS activated two sources sequentially within SI: one in the posterior bank of the central sulcus and another in the crown of the postcentral gyrus, corresponding to Brodmann's areas 3b and 1, respectively. Activities from area 3b consisted of 20- and 30-ms responses.
