This descriptive study aimed to assess the facilities and barriers that nurses in leading positions endure with respect to the nursing team's compliance to measures for preventing occupational exposure involving biological materials, based on Rosenstock's Health Belief Model. The study was carried out with 87 nurses of a university hospital in Sao Paulo, Brazil, in the year of 2006. Data were collected through a semistructured form with open and closed questions and analyzed through Content Analysis. Individual protection equipment was mentioned as the greatest form for preventing accidents, but lack of compliance to usage and incorrect use were indicated as barriers to accident prevention and as the main reasons for their occurrence. It is important for these nurses to be prepared to develop individualized and motivating strategies focused on compliance to the use of individual protection equipment in their work sectors.

Indoloindolizines: The Complete Story of a Polycyclic Aromatic Scaffold from Theoretical Design to Organic Field-Effect Transistor Applications.

The development of stable and tunable polycyclic aromatic compounds (PACs) is crucial for the advancement of organic optoelectronics. Conventional PACs, such as acenes, often suffer from poor stability due to photooxidation and oligomerization, which are linked to their frontier molecular orbital energy levels. To address these limitations, we designed and synthesized a new class of π-expanded indoloindolizines by merging indole and indolizine moieties into a single polycyclic framework.

Early Initiation of Bundle Sheath Cells During Leaf Development as Visualised by SCARECROW Expression in Dicotyledonous C Plants.

Department of Ecology & Evolutionary Biology, University of Toronto, Toronto, Ontario, Canada.
The C type of dicotyledonous plants exhibit a higher density of reticulate veins than the C type, with a nearly 1:1 ratio of mesophyll cells (MCs) to bundle sheath cells (BSCs). To understand how this C-type cell pattern is formed, we identified two SCARECROW (SCR) genes in C Flaveria bidentis, FbSCR1 and FbSCR2, that fully or partially complement the endodermal cell layer-defective phenotype of Arabidopsis scr mutant. We then created FbSCRs promoter β-glucuronidase reporter (GUS) lines of F.

Faculty of Applied Sciences, Macao Polytechnic University, Macao, SAR, China. Electronic address:
As a crucial drug target, KRAS can regulate most cellular processes involving guanosine triphosphate (GTP) hydrolysis. However, the mechanism of GTP hydrolysis has remained controversial over the past decades. Here, several different GTP hydrolysis mechanisms catalyzed by wild-type KRAS (WT-KRAS) and KRAS mutants were discussed via four QM/MM calculation models.

An ulnar nerve (UN) palsy is devastating for hand function, resulting in an intrinsic minus position or claw hand with a loss of pinch grip. Distal nerve transfers facilitate faster reinnervation of hand intrinsic muscles in cases of proximal ulnar nerve lesions. The traditional anterior interosseous nerve (AIN) to UN motor transfer is commonly used, however, this still leads to long reinnervation times for the distal intrinsic muscles, important for the thumb to index pinch grip.
