EBUS-GS and VBN for GGO lesions
No full textBackground: Endobronchial ultrasonography with guide sheath (EBUS-GS) could be useful for diagnosing ground-glass opacity (GGO) predominant-type lesions in the peripheral lung. Furthermore, several studies have reported that transbronchial biopsy using EBUS-GS and virtual bronchoscopic navigation (VBN) was safe and effective for diagnosing small peripheral lung lesions. Our objectives were to diagnose solitary peripheral GGO predominant-type lesions by transbronchial biopsy using EBUS-GS and VBN under radiographic fluoroscopic guidance, and to evaluate the clinical factors associated with diagnostic yield. Methods: The medical records of 169 patients with GGO predominant-type lesions who underwent transbronchial biopsy using EBUS-GS and VBN under radiographic fluoroscopic guidance were retrospectively reviewed. Results: Endobronchial ultrasonography images could be obtained for 156 (92%) of 169 GGO predominant-type lesions, and 116 (69%) were successfully diagnosed by this method (20 of 31 pure GGO lesions [65%]; 96 of 138 mixed GGO predominant-type lesions [70%]). The mean size of diagnosed lesions was significantly larger than that of nondiagnosed lesions (22 mm versus 18 mm, p < 0.01). Regarding diagnostic yield based on computed tomography sign, cases with presence of a bronchus leading directly to a lesion had significantly higher diagnostic yield than the other lesions (p < 0.01). Conclusions: The addition of VBN to EBUS-GS could be useful in clinical practice for diagnosing GGO predominant-type lesions in the peripheral lung

Allen E. Paulson
No full textAllen E. Paulson (1922-2000), an Iowa native, was highly influential in the fields of aviation and gaming as well as in the Georgia Southern Community. On his own since age 13, he joined the US Army during World War II and studied engineering at the University of West Virginia. After the War, he worked for TWA as a flight engineer and earned his pilot\u27s license. Paulson went on to be very successful dealing in second-hand planes and was the head of American Jet Industries when it acquired what would eventually become Gulfstream Aerospace. He was also a leading owner and breeder of racehorses including Cigar, the most prize money winningest horse in history,
Because of his philanthropy, the Allen E. Paulson College of Engineering and Computing is named in his honor as is the Allen E. Paulson Student Scholarship that provides assistance to engineering and Technology students. His company, Gulfstream, created the Gulfstream Scholarships to assist students in any of Georgia Southern’s engineering programs. He is also a member of the Georgia Southern Athletics Hall of Fame for his significant contribution to the stadium that is named in his honor.
Allen E. Paulson received the Honorary Doctor of Science degree on June 14, 1997.https://digitalcommons.georgiasouthern.edu/gs-honorary-degrees/1002/thumbnail.jp
Role of the GTP-binding protein Gs in the β-adrenergic modulation of cardiac Ca channels
No full textIn the heart, the guanosine 5′-triphosphate (GTP)-binding protein Gs is activated by hormone binding to β-adrenergic receptors and stimulates the intracellular cyclic adenosine 3′,5′-monophosphate (cAMP) pathway that leads to phosphorylation of L-type Ca channels by the cAMP-dependent protein kinase A [28]. Additionally, Gs can modulate cardiac Ca channels directly in cell-free systems [57]. In order to examine the question of whether these pathways could be separated functionally and whether they act independently or synergistically on L-type Ca channels in intact cells, the whole-cell Ca current (ICa) and the respective current density were measured in guinea-pig ventricular myocytes at 0 mV. The following results were obtained.
First, typically, the ICa density increased from 12 to 40 μA/cm2 following application of 1 μM isoproterenol (ISP) to myocytes bathed in solutions containing 1.8 mM CaCl2. However, 1 μM ISP enhanced ICa only from 9 to 17 μA/cm2 after inhibition of the protein kinase A by dialysis of 0.5 mM Rp-cAMPS (the Rp-isomer of adenosine 3′,5′-monophosphorothioate) in the presence of 0.5 mM GTP. Withdrawal of GTP from the dialysate attenuated the effects of ISP on ICa. Thus, Rpc-AMPS unmasks a GTP-dependent component of the β-adrenergic stimulation of ICa, which probably reflects the direct stimulation of Ca channels by Gs under block of cAMP-dependent phosphorylation.
Second, in cells under dialysis with 100 or 200 μM cAMP, bath application of 20–40 μM 3-isobutyl-1-methylxanthine (IBMX) enhanced the ICa density to about 41 μA/cm2 indicating saturation of the cAMP pathway. Under this condition, 1 μM ISP was without significant effect on ICa. This result may suggests that direct Gs stimulation is rather ineffective on Ca channels after maximal cAMP-dependent phosphorylation. Alternatively, maximal stimulation of the cAMP pathway may also interfere with the activation of the Gs pathway in intact myocytes.
Third, simultaneous application of 1 μM ISP and 40 μM IBMX enhanced ICa up to densities of around 75 μA/cm2 during cell dialysis with 100 μM cAMP, an effect much stronger than that exerted by IBMX alone under similar conditions. Since it seems likely that Gs is activated more quickly, than the cAMP pathway during application of the ISP/IBMX mixture, the latter result suggests that a direct effect of Gs may act to prime L-type Ca channels for cAMP-dependent phosphorylation during β-adrenergic stimulation of cardiac myocytes
