The Hippo/Yki and RB/E2F pathways both regulate tissue growth by affecting cell proliferation and survival, but interactions between these parallel control systems are poorly defined. In this study, we demonstrate that interaction between Drosophila E2F1 and Sd disrupts Yki/Sd complex formation and thereby suppresses Yki target gene expression. RBF modifies these effects by reducing E2F1/Sd int...

The three-dimensional load displacement behavior of nine fresh adult L5-S1 spine motion segments was studied. Static test forces up to 160 N in anterior, posterior, and lateral shear, test forces up to 320 N in compression, and test moments up to 15.7 Nm in flexion, extension, lateral bending, and torsion were used. The six displacements of the center of the inferior L5 endplate were measured 1...

Sound onsets are salient and behaviorally relevant, and most auditory neurons discharge spikes locked to such transients. The acoustic parameters of sound onsets that shape such onset responses are unknown. In this paper is analyzed the timing of spikes of single neurons in the primary auditory cortex of barbiturate-anesthetized cats to the onsets of tone bursts. By parametric variation of soun...

Three acanthocephalan species, Sphaerirostris turdi from the island thrush (Turdus poliocephalus), and Porrorchis centropusi and Porrorchis kinsellai n. sp., both from Philippine scops owls (Otus megalotis), are reported from Aurora Province, Luzon Island, Philippines. Porrorchis kinsellai n. sp. can be readily differentiated from previously known members of the genus by an almost perfectly sph...

BACKGROUND The neural mechanisms of anesthetic vapors have not been studied in depth. However, modeling and experimental studies on the intravenous anesthetic propofol indicate that potentiation of γ-aminobutyric acid receptors leads to a state of thalamocortical synchrony, observed as coherent frontal alpha oscillations, associated with unconsciousness. Sevoflurane, an ether derivative, also p...

GOAL The aim of the study is to define the MRI appearance of disorder in the Junctional zone (JZ) in women with adenomyosis compared to those without it, given the importance of the JZ in the regulation of various reproductive events. MATERIALS AND METHODS This was a prospective, comparative and open study. Patients with adenomyosis have been sorted in target group, n = 82, while the control ...

We evaluated a new agarose-gel-electrophoretic procedure (Corning) (I) for separatingandquantitating of highdensity lipoprotein cholesterol (HDLC), comparing it with the modified Lipid Research Clinics (LRC) procedure (heparin 183 kilounits/L, MnCI2 92 mmol/L) (U). Method I was insensitive to an HDLC concentration of 50 mg/L, but gave a linear dose-response curve between 130 and 1200 mg/L. Meth...

We have studied 14 female patients undergoing elective laparoscopy under general anaesthesia with peritoneal insufflation of carbon dioxide in order to examine changes in physiological deadspace (VDphys), arterial to end-tidal carbon dioxide partial pressure difference (PaCO2-PE' CO2) and PaCO2. VCO2 increased after insufflation of carbon dioxide with a mean (SD) maximum increase of 32 (28)% co...
