The Effectiveness of Internal Maxillary Sinus Elevation Using Controlled Hydrodynamic or Pneumatic Pressure: An Ex-vivo Experimental and Preliminary Animal Study.

Objective The aim of this experimental study was to test the possibility of applying internal sinus elevation techniques using controlled hydrodynamic or pneumatic pressure and evaluate their elevation effectiveness. Materials and methods A device was specially designed for this study and was used to elevate the sinus membrane internally in 12 halves of freshly slaughtered sheep heads. The sample was divided into two groups randomly according to the type of controlled pressure applied (hydrodynamic or pneumatic).

Weight change after colectomy for ulcerative colitis.

Background And Objective: Weight change after colectomy for ulcerative colitis is unknown. The main objective of this study was to describe weight change during surgical management of ulcerative colitis.

Methods: All patients, underwent a subtotal colectomy, then a proctectomy with J ileal pouch anal anastomosis protected by an ileostomy, and finally an ileostomy closure in the context of ulcerative colitis at the Nancy University Hospital from May 2014 to October 2020, were included.

Antibacterial Effect of Colloidal Suspensions Varying in Silver Nanoparticles and Ions Concentrations.

A lot of effort has been dedicated recently to provide a better insight into the mechanism of the antibacterial activity of silver nanoparticles (AgNPs) colloidal suspensions and their released silver ionic counterparts. However, there is no consistency regarding whether the antibacterial effect displayed at cellular level originates from the AgNPs or their ionic constitutes. To address this issue, three colloidal suspensions exhibiting different ratios of AgNPs/silver ions were synthesized by a wet chemistry method in conjunction with tangential flow filtration, and were characterized and evaluated for their antimicrobial properties against two gram-negative, () and (), and two gram-positive, () and (), bacterial strains.

Do Periodontal Pathogens or Associated Virulence Factors Have a Deleterious Effect on the Blood-Brain Barrier, Contributing to Alzheimer's Disease?

The central nervous system (CNS) is protected by a highly selective barrier, the blood-brain barrier (BBB), that regulates the exchange and homeostasis of bloodborne molecules, excluding xenobiotics. This barrier forms the first line of defense by prohibiting pathogens from crossing to the CNS. Aging and chronic exposure of the BBB to pathogens renders it permeable, and this may give rise to pathology in the CNS such as Alzheimer's disease (AD).

Valuing health-related quality of life using a hybrid approach: Tunisian value set for the EQ-5D-3L.

Objective: To develop a value set for EQ-5D-3L based on the societal preferences of the Tunisian population.

Methods: A representative sample of the Tunisian general population was obtained through multistage quota sampling involving age, gender and region. Participants (n = 327), aged above 20 years, were interviewed using the EuroQol Portable Valuation Technology in face-to-face computer-assisted interviews.

Expression of cannabinoid and cannabinoid-related receptors in the oral mucosa of healthy cats and cats with chronic gingivostomatitis.

Objectives: Feline chronic gingivostomatitis (FCGS) is an oral disease. Cats with FCGS experience intense oral pain. Some cats remain refractory to current therapies based on dental extraction and adjuvant medical treatment; it is therefore necessary to investigate alternative therapeutic targets involved in inflammatory mechanisms and pain, namely the endocannabinoid system (ECS).

Pseudochylothorax: An unusual mode of revelation of pleural metastasis from solid tumor.

Introduction: Pseudochylothorax is a rare cause of pleural effusion. Sometimes confounded with chylothorax, firm diagnosis relies on analysis of the pleural liquid: exudative liquid (protein >30 g/L, lactate dehydrogenase >200 UI/L) with a high level of cholesterol (usually >200 mg/dL), low level of triglyceride (usually <110 mg/dL), cholesterol total/triglyceride ratio >1, absence of chylomicron, and in some cases the presence of cholesterol crystals. Pseudochylothorax is secondary to tuberculosis and rheumatoid arthritis in nearly 90% of cases.

Chronic Gingivostomatitis with Esophagitis in Cats.

Background: Chronic gingivostomatitis in cats (FCG) is a debilitating disease with potentially deleterious effects on overall health.

Hypothesis/objectives: Little is known about the pathophysiology and overall impact of FCG. The aims of our study were to investigate whether gingivostomatitis occurs concurrently with esophagitis, if FCG treatment contributes to esophagitis and if esophagitis exacerbates signs of FCG.

Evaluation of analgesic effect and absorption of buprenorphine after buccal administration in cats with oral disease.

Objectives The objective of this study was to evaluate the analgesic effect and absorption of buprenorphine after buccal administration in cats with oral disease. Methods Six adult client-owned cats with chronic gingivostomatitis (weighing 5.1 ± 1.

Successful management of jejunojejunal anastomosis dehiscence by extra-abdominal exteriorization and bandaging in a cat with septic peritonitis.

Duodenal and jejunal resections were performed in a cat with septic peritonitis due to small intestinal perforations by a linear foreign body. Three days later jejunal resection and anastomosis were repeated due to dehiscence of the anastomosis site. This segment of intestine was exteriorized through the body wall and managed with bandages for 5 days before it was surgically replaced into the abdomen.

Biogenetic explanations and emotional reactions to people with schizophrenia and major depressive disorder.

Using population-based data, the relationship between biogenetic causal beliefs and emotional reactions to persons with schizophrenia or depression was examined. Biogenetic attributions elicited either negative emotions alone or pro-social and negative emotions at the same time. Biogenetic attributions seem not helpful for improving emotional reactions to people with mental disorders.

Periodontal disease as a potential factor for systemic inflammatory response in the dog.

Periodontal disease is an inflammatory disease that has numerous consequences both locally and systemically The aim of this study was to assess whether periodontal disease causes systemic inflammatory response in otherwise healthy, adult dogs. We estimated the total mouth periodontal score (TMPS), measured the concentration of C-reactive protein (CRP), hematocrit, and albumin, and determined the white blood cell (WBC) and polymorphonuclear cell (PMN) counts in client-owned dogs. There was a statistically significant relationship between the gingival bleeding index (TMPS-G) and CRP concentration, and WBC and PMN counts, possibly during the active periods of periodontal tissue destruction.

Toughness is less important than chemical composition of Arbutus leaves in food selection by Poecilimon species.

•  We tested the hypothesis that unavoidably soft young leaves, which are therefore vulnerable to herbivory, should rely heavily on chemical defense to avoid overconsumption by herbivores. •  Along with area lost to herbivores, parameters related to chemical and mechanical defense were monitored in two evergreen Mediterranean sclerophylls (Arbutus unedo and Arbutus andrachne) during spring and early summer, when newly growing and old leaves co-occur on the same branches. •  During the lag phase of growth, young leaves were soft, rich in phenolics and gallotannins (up to 50% and 14% w/w, respectively) and highly astringent.

Late results in the management of choledochal cysts.

From 1971 to 1990, 18 children were surgically managed for choledochal cysts at two Berlin pediatric surgical units. Eight patients underwent an internal drainage procedure, eight a Roux-en-Y hepaticojejunostomy and one a choledochoplasty. The children were followed-up 2 to 20 years later (median: 8.
