With the advancement in molecular biology, several metabolic and physiological processes have been elucidated at molecular levels discovering the involvement of different genes. Since the advent of plant transformation 33 years ago, use of plant transformation techniques sparked an interest in fundamental and applied research leading to the development of biological and physical methods of fore...

Abstract Keratinized tissues, including whiskers, are ideal for acquiring a record of physiological parameters. Most tissues provide snapshot status; however, whiskers may support longitudinal sampling reproductive and stress-related hormones, if hormones incorporated as grow concentrations change with state. Whiskers from female Steller sea lions (Eumetopias jubatus) northern fur seals (Callor...

The need to better understand whisker growth has dramatically increased as component suppliers convert from tin-lead (SnPb) finishes to Pb-free finishes of Sn and low-alloy-content Sn-based finishes. Whiskers are spontaneous growth of metal filaments emanating from the finish surface. The issues with whiskers are they may grow long enough to cause short circuiting or break off and interfere wit...

We model experience-dependent plasticity in the cortical representation of whiskers (the barrel cortex) in normal adult rats, and in adult rats that were prenatally exposed to alcohol. Prenatal exposure to alcohol (PAE) caused marked deficits in experience-dependent plasticity in a cortical barrel-column. Cortical plasticity was induced by trimming all whiskers on one side of the face except tw...

Rats use their large facial whiskers to discriminate the spatial features of objects. Despite numerous electrophysiological recording studies in the central trigeminal whisker representations that document neurons tuned to the direction of whisker deflection, there is no behavioral evidence to date that rats can use their whiskers to discriminate between object orientations. In the present stud...

The dorsolateral striatum (DLS) receives extensive projections from primary somatosensory cortex (SI), but very few studies have used somesthetic stimulation to characterize the sensory coding properties of DLS neurons. In this study, we used computer-controlled whisker deflections to characterize the extracellular responses of DLS neurons in rats lightly anesthetized with isoflurane. When mult...

Roughly 20 years ago Valentino Braitenberg published a book on vehicles—a treatment of the amazingly complex behavior of a variety of very simple machines (Braitenberg 1984). This approach was inspired by the “law of uphill analysis and downhill invention.” Accordingly it is easier to design a mechanism to do something from scratch than to figure out just how nature has contrived to do it. Alth...

In this paper, potassium titanate whiskers was prepared via the Molten salt synthesis on surface of cordierite ceramics for regeneration diesel particulate filters (DPFs). SEM, EDS, XRD, FT-IR, TG-DSC and TPO were carried out to characterize morphology, microstructure, growth mechanism catalytic performance samples. Potassium with diameter (100–500 nm) length (about 3 μm) is tightly combined ce...

Contribution of supragranular layers to sensory processing and plasticity in adult rat barrel cortex. J. Neurophysiol. 80: 3261-3271, 1998. In mature rat primary somatic sensory cortical area (SI) barrel field cortex, the thalamic-recipient granular layer IV neurons project especially densely to layers I, II, III, and IV. A prior study showed that cells in the supragranular layers are the faste...

Abstract The influence mechanism of basicity on the reduction swelling index (RSI) iron ore briquettes was investigated using SEM analysis and Factsage 7.3 thermodynamic calculations based addition pure CaO to Bayan Obo concentrate. results revealed that solid solution Ca 2+ in FeO lattice increased with briquettes, whereas diffusion channels Fe ions during process from resulted formation a gre...
