Tailoring Cu-SiO Interaction through Nanocatalyst Architecture to Assemble Surface Sites for Furfural Aqueous-Phase Hydrogenation to Cycloketones.

In this contribution, nanocatalysts with rather diverse architectures were designed to promote different intimacy degrees between Cu and SiO and consequently tune distinct Cu-SiO interactions. Previously synthesized copper nanoparticles were deposited onto SiO (NPCu/SiO) in contrast to ordinarily prepared supported Cu/SiO. NPCu@SiO and SiO@Cu core-shell nanocatalysts were also synthesized, and they were all bulk and surface characterized by XRD, TGA, TEM/HRTEM, H-TPR, XANES, and XPS.

Harm reduction: trends being disputed in health policies.

Objective: to identify the underlying harm reduction trends in Brazilian drug policies.

Method: The research, qualitative in nature, used in-depth interviews with experts in the field. The recorded and transcribed material was analyzed via the content analysis method.

Radiographic evaluation of maxillofacial region in oncology patients treated with bisphosphonates.

Objective: This study aimed to identify radiographic alterations in patients administered bisphosphonate treatment that would permit early diagnosis of osteonecrosis of the jaw.

Study Design: A prospective study was conducted with clinical and radiographic analysis of 60 patients divided into 2 groups. Thirty patients treated with zoledronate were included in group 1, and 30 patients that had never been treated with bisphosphonate were included in group 2.

Relation between respiratory muscle strength with respiratory complication on the heart surgery.

Objective: To check the respiratory muscle strength in cardiac surgery and the relationship with the postoperative pulmonary complications.

Methods: Sixty-tree adult's patients undergoing elective cardiac surgery were enrolled in this study. In the day of the surgery all patients did the respiratory muscle strength test.

Postmortem acinar autolysis in rat sublingual gland: a morphometric study.

Objective: To analyze and to quantify morphological acinar postmortem changes in rat sublingual glands (SLG). MATERIAL AND METHODSs: Fifty rats were divided into two groups of 25 animals each. Group I was used for morphological and morphometric evaluations and group II for the determination of gland density and processed gland volume.

Assessment of linear and angular measurements on three-dimensional cone-beam computed tomographic images.

Objective: The purpose of this research was to provide further evidence to demonstrate the precision and accuracy of maxillofacial linear and angular measurements obtained by cone-beam computed tomography (CBCT) images.

Study Design: The study population consisted of 15 dry human skulls that were submitted to CBCT, and 3-dimensional (3D) images were generated. Linear and angular measurements based on conventional craniometric anatomical landmarks, and were identified in 3D-CBCT images by 2 radiologists twice each independently.

3-D volume rendering maxillofacial analysis of angular measurements by multislice CT.

Objective: This study was designed to determine the precision and accuracy of angular measurements using three-dimensional computed tomography (3D-CT) volume rendering by computer systems.

Study Design: The study population consisted of 28 dried skulls that were scanned with a 64-row multislice CT, and 3D-CT images were generated. Angular measurements, (n = 6) based upon conventional craniometric anatomical landmarks (n = 9), were identified independently in 3D-CT images by 2 radiologists, twice each, and were then performed by 3D-CT imaging.

Evaluation of TMJ articular eminence morphology and disc patterns in patients with disc displacement in MRI.

The aim of this study was to assess the shape of the temporomandibular joint (TMJ) articular eminence and the articular disc configuration and position in patients with disc displacement. TMJ magnetic resonance images (MRI) of 14 patients with bilateral disc displacement without unilateral reduction were analyzed. Articular eminence morphology was characterized as box, sigmoid, flattened, or deformed.

Comparative study of single and multislice computed tomography for assessment of the mandibular canal.

Objective: The purpose of this study was to evaluate the accuracy of relative measurements from the roof of the mandibular canal to the alveolar crest in multislice (multidetector) computed tomography (MDCT) and single-slice computed tomography (SSCT).

Material And Methods: The sample consisted of 26 printed CT films (7 SSCT and 19 MDCT) from the files of the LABI-3D (3D Imaging Laboratory) of the School of Dentistry of the University of São Paulo (FOUSP), which had been acquired using different protocols. Two observers analyzed in a randomized and independent order a series of 22 oblique CT reconstructions of each patient.

Clinical and imaging correlations of Treacher Collins syndrome: report of two cases.

Mandibulofacial dysostosis (Treacher Collins Syndrome) is an autosomal dominant genetic disorder that probably derives from inhibition of the facial structures from the first and second branchial arches. The facial pattern of the syndrome is a convex facial profile with a prominent nose above a retruded chin. The eyes are deformed by antimongoloid slant of the palpebral fissures and facial bones are hypoplastic.

Malignant fibrous histiocytoma (undifferentiated high-grade pleomorphic sarcoma) occurring in tuberous sclerosis: a case report.

Tuberous sclerosis is an autosomal dominant genetic disorder that is characterized by the early development of hamartomas, malformations, and congenital tumors of the nervous system, skin, kidneys, lungs, and heart. Variable clinical expressivity has been reported and more than one gene can be responsible for the disorder. Benign neoplasias accompanying the syndrome are common but malignant neoplasias are rare, being generally mesenchymal and possibly affecting the jaws.

Quantitative age-related differences in human sublingual gland.

Objective: To quantify morphological age- and gender-related differences in human sublingual glands (SLG).

Design: Ninety right human SLG from necropsies were distributed by gender and age groups. Individuals with ages ranging from 7 months to 92 years were divided into Groups I (0-30 years), II (31-60 years) and III (61-92 years).
