the short half-life of terbutaline sulphate (tbs) requires frequent dosing for controlling chronic pulmanary disorders, such as night asthma. the purpose of the present study was to prepare sustained-release (sr) tablets of tbs to decrease the number of doses frequency and to promote the paitent compliances. it was also desirable to evaluate the capability of natural gums for preparation of sr ...

The theta oscillation (4-8 Hz) is a pivotal form of oscillatory activity in the hippocampus that is intermittently concurrent with gamma (25-100 Hz) burst events. In in vitro preparation, a stimulation protocol that mimics the theta oscillation, theta burst stimulation (TBS), is used to induce long-term potentiation. Thus, TBS is thought to have a distinct role in the neural network of the hipp...

Nonhuman primate neuroanatomical studies have identified a cortical pathway from the superior temporal sulcus (STS) projecting into dorsal subregions of the amygdala, but whether this same pathway exists in humans is unknown. Here, we addressed this question by combining theta burst transcranial magnetic stimulation (TBS) with fMRI to test the prediction that the STS and amygdala are functional...

Monopolar electrocautery is a fast and elegant cutting option. However, as it creates surgical smoke containing polycyclic aromatic hydrocarbons (PAHs), it may be hazardous to the health of the surgical team. Although new technologies, such as feedback mode (FM) and Teflon-coated blades (TBs), reduce tissue damage, their impact on surgical smoke creation has not yet been elucidated. Therefore, ...

Early detection of oral premalignant lesions (OPMLs) by visual inspection with toluidine blue has not been addressed. We conducted a community-based randomized controlled trial to assess whether using toluidine blue as an adjunctive tool for visual screening had a higher detection rate of OPMLs and could further reduce the incidence of oral cancer. In 2000, in Keelung, we randomly assigned a to...

In this issue of the Journal, Lee and colleagues 1 from Hong Kong describe their assessment of the impact of the 2001 Bethesda System (TBS) revisions on their cytology practice. The primary focus of the study was to assess the impact of the conversion from TBS 1991 to the 2001 version on the frequency of atypical squamous cells (ASC) diagnoses. As noted in prior commentaries, ASC is not a diagn...

Abstract Background Bone mineral density (BMD) and trabecular bone score (TBS) are moderately correlated. TBS is sometimes used as an adjuvant to BMD in the fracture risk assessment. Some individuals with normal or osteopenia, have more degraded TBS. We aimed identify factors associated worse than non-osteoporotic elderly population. Methods The study subjects were selected from 2384 women men ...

Carp were transferred from 25 degrees C water to a calorimeter at 15 degrees C or from 15 degrees C water to a calorimeter at 25 degrees C. During cooling, dorsal muscle temperature (Tdm) and mean body temperature (Tb) were continuously monitored. During the first minutes Tb changed rapidly, while Tdm changed only slightly. In a 0.468-dg fish, Tdm decreased to two-thirds of the final value in 8...

Body temperature (Tb) influences almost every aspect of a reptile's physiology and behavior (for reviews, see Huey, 1982; Lillywhite, 1987). For example, Tb can alter both auditory capacity (Werner, 1976, 1983) and locomotory performance (Bennett, 1980, 1990), thus facilitating or impairing escape from and defense against predators (e.g., Christian and Tracy, 1981; Hertz et al., 1982; Goode and...

Memory consolidation theory posits that newly acquired information passes through a series of stabilization steps before being firmly encoded. We report here that in rat and mouse, hippocampus cell adhesion receptors belonging to the β1-integrin family exhibit dynamic properties in adult synapses and that these contribute importantly to a previously unidentified stage of consolidation. Quantita...
