Surgery for obesity.

2005

PURPOSE OF REVIEW Bariatric surgery today is the only effective therapy for morbid obesity. Commonly performed procedures include adjustable gastric banding and vertical banded gastroplasty, variations of the Roux-en-Y gastric bypass, biliopancreatic diversion or duodenal switch, and mixed procedures. This review discusses key issues in the surgical management of morbid obesity. RECENT FINDINGS The two most common bariatric procedures performed worldwide are laparoscopic adjustable gastric banding and laparoscopic Roux-en-Y gastric bypass. Controversy exists regarding the best surgical procedure. Weight loss decreases according to the procedures performed in following decreasing order: bili…

Multiple roles for ISWI in transcription, chromosome organization and DNA replication.

2003

ISWI functions as the ATPase subunit of multiple chromatin-remodeling complexes. These complexes use the energy of ATP hydrolysis to slide nucleosomes and increase chromatin fluidity, thereby modulating the access of transcription factors and other regulatory proteins to DNA. Here we discuss recent progress toward understanding the biological functions of ISWI, with an emphasis on its roles in transcription, chromosome organization and DNA replication.

Epidemiology ofSalmonella typhimurium: ribosomal DNA analysis of strains from human and animal sources

1993

SUMMARYSalmonella typhimuriumis the most frequently identified serovar ofSalmonellain Italy. This serovar is characterized by the widespread dissemination among human and non-human sources of phenotypically and genetically well-differentiated clones.In this study 457 strains ofS. typhimuriumisolated in Italy in the years 1982–91 from human and animal sources were submitted to characterization by the rDNA fingerprinting technique. Application of this typing method, after digestion of chromosomal DNA withHincII endonuclease, confirmed the greatest genetic differentiation of clones ofS. typhimurium, allowing reliable identification of 45 rDNA patterns linked into 9 major clusters. rDNA pattern…

Simultaneous detection of Carnobacterium and Leuconostoc in meat products by multiplex PCR.

2004

M.C. MACIAN, E. CHENOLL AND R. AZNAR. 2004. Aims: To develop a multiplex PCR approach for simultaneous detection of Leuconostoc and Carnobacterium and its validation in meat products. Methods and Results: Two multiplex PCR assays were developed using newly designed 16S rDNA-directed primers adapted to the current taxonomic situation of genera Leuconostoc and Carnobacterium that allow: (i) simultaneous detection of both genera, and members of the nonmotile species of genus Carnobacterium and (ii) identification in a single assay of the nonmotile species C. divergens, C. maltaromicum and C. gallinarum. Sensitivity values of 10 3 and 10 4 CFU g )1 were determined for multiplex PCR detection of…

Lactic acid bacteria associated with vacuum-packed cooked meat product spoilage: population analysis by rDNA-based methods.

2007

Aim:  To determine the lactic acid bacteria (LAB) implicated in bloating spoilage of vacuum-packed and refrigerated meat products. Methods and Results:  A total of 18 samples corresponding to four types of meat products, with and without spoilage symptoms, were studied. In all, 387 colonies growing on de Man, Rogosa and Sharpe, yeast glucose lactose peptone and trypticase soy yeast extract plates were identified by internal spacer region (ISR), ISR-restriction fragment length polymorphism and rapid amplified ribosomal DNA restriction analysis profiles as Lactobacillus (37%), Leuconostoc (43%), Carnobacterium (11%), Enterococcus (4%) and Lactococcus (2%). Leuconostoc mesenteroides dominated …

Impact of a Three Amino Acid Deletion in the CH2 Domain of Murine IgG1 on Fc-Associated Effector Functions

2008

Abstract Four murine IgG subclasses display markedly different Fc-associated effector functions because of their differential binding to three activating IgG Fc receptors (FcγRI, FcγRIII, and FcγRIV) and C1q. Previous analysis of IgG subclass switch variants of 34-3C anti-RBC monoclonal autoantibodies revealed that the IgG1 subclass, which binds only to FcγRIII and fails to activate complement, displayed the poorest pathogenic potential. This could be related to the presence of a three amino acid deletion at positions 233–235 in the CH2 domain uniquely found in this subclass. To address this question, IgG1 insertion and IgG2b deletion mutants at positions 233–235 of 34-3C anti-RBC Abs were …

The influence of platform switching in dental implants. A literature review.

2010

Introduction: The platform switching concept involves the reduction of the restoration abutment diameter with respect to the diameter of the dental implant. In 1991, dental implants of 5 and 6 mm diameter platforms were introduced. However, matching-diameter prosthetic abutments were not available. These implants were restored with “standard”-diameter prosthetic components (4,1 mm). Long-term follow up around these wide-platforms showed higher levels of bone preservation. In time, it has been called platform switching. The first case report applying this concept was indexed in MedLine in 2005. Materials and Methods: The aim of this article is to carry out a literature review of articles whi…

Comparison of conventional twist drill protocol and piezosurgery for implant insertion: an ex vivo study on different bone types.

2015

Objective The aim of this ex vivo study was to compare implant insertion procedures using piezosurgery and conventional drilling in different qualities of bone. Implant bed preparation time, generated heat, and primary implant stability were analyzed. Material and methods Fresh ex vivo porcine bone block samples (cancellous, mixed, and cortical bone) were obtained. The bone quality was quantified by ultrasound transmission velocity (UTV). Each bone sample received three implants of the same diameter using each of the techniques of piezosurgery and conventional twist drills. Time for preparation was taken and the temperature while performing the osteotomy was measured using infrared spectros…
