Bacteria use a wide range of immune pathways to counter phage infection. A subset of these genes shares homology with components of eukaryotic immune systems, suggesting that eukaryotes horizontally acquired certain innate immune genes from bacteria. Here, we show that proteins containing a NACHT module, the central feature of the animal nucleotide-binding domain and leucine-rich repeat containing gene family (NLRs), are found in bacteria and defend against phages.

Objectives: Surgical simulation models have been shown to improve surgical skill and confidence for surgical residents before real life procedures. Surgical simulators can be similarly applied in undergraduate medical education as a tool to introduce students to the field of otolaryngology.
Methods: Ear models were created using 3D printing and high-performance silicone.
Introduction: The purpose of this study was to compare the stress distributions in the teeth treated through minimally invasive access (MIA) designs to those of the teeth treated through traditional straight-line access and their relationship to the final restoration using three-dimensional finite element analysis (FEA).
Materials And Methods: Four FEA models of an extracted mandibular first molar were constructed. An intact model served as the control, whereas the other three were prepared with either an MIA or traditional straight-line access.
Reports on the abundances and on metal concentrations in intertidal estuarine invertebrates from the Eastern Tropical Pacific are rare. Thus, the objectives of this report are to make accessible data on the abundances (1984-1987, 49 dates; 2013, 12 dates) of sipunculans, brachiopods and hemichordates from a sand-mud flat; and on trace metals (1996, 2000) and abundances (2015, 3 dates) of sipunculans and brachiopods at a sand flat in the Gulf of Nicoya estuary (10o N-85o W). Cores (17.

Although computed tomography (CT) and magnetic resonance (MRI) imaging are capable of providing 3D anatomical descriptions, this type of technology is not readily available in a clinic setting. Current imaging of the oropharynx is performed using a light source and tongue depressors.
View Article and Find Full Text PDFOcular myositis (OM) is a rare clinical entity characterized by idiopathic, nonspecific inflammation of primarily or exclusively extraocular muscles (EOM). Presentation usually encompasses painful diplopia, exacerbated by eye movement. We report two cases of idiopathic OM with unique characteristics.

Bartonella henselae is the etiologic agent more frequently involved. There are only a few recent reports demonstrating the disease after transplantation, although the illness is not infrequent in immunologically competent people.

We conducted the present study to determine if age at disease onset modulates the clinical characteristics and outcome of SSc patients. The Spanish Scleroderma Study Group recruited 1037 patients with a mean follow-up of 5.

In typical GERD symptoms, an 8-week treatment with PPIs is satisfactory in most cases (> 90%). Response rates to PPIs in GERD are highly variable, as they also rely on an appropriate clinical diagnosis of the disease; endoscopy differentiates the macroscopic GERD phenotype.

This study aimed to contribute with long-term data on the abundance fluctuations of two species of echinoderms from a tropical tidal flat. From February 1984 to December 1986, March 1985 to April 1987, and July 1994 to September 1996 (total: 76 dates), core samples (17.

In recent years, these organisms have been the center of activity of studies focusing on the phylogenetic relationships of the chordates. In 1980, a survey of the benthos at 48 stations in the Gulf of Nicoya estuary, Pacific coast of Costa Rica, yielded 265 specimens of the lancelet Branchiostoma californiense.

Our aim was to analyze the joint effect of BMI with the grade of esophageal damage over symptoms' intensity of GERD.
Methods: We used a questionnaire with a Likert scale for severity of symptoms related to GERD.
During October and November 1998 (rainy season), and December, February and March 1999 (dry season), larvae distribution of Petrolisthes armatus and associated decapods were sampled in three different sites at the Punta Morales peninsula, Gulf of Nicoya, Costa Rica. A total of 6014 decapod larvae were collected, and 73 belonged to the genus Petrolisthes spp. No significant total larval density differences were found between seasons (p > 0.

Objective: The etiology, comorbidity, metabolism, and treatment response vary among overweight and obesity types I, II and III individuals. We assessed the association between obesity type with body mass index, waist circumference and tolerance to a daily dose of 15 mg of sibutramine.
Materials And Methods: A sample of 701 individuals recruited from 47 health centers was analyzed.
Material And Methods: Retrospective multi-center analysis of women diagnosed with borderline ovarian tumor and treated between January 1990 and December 1997. A national survey was conducted, in which 457 patients from 27 centers corresponding to ten of Spain's autonomous communities were analyzed.
Results: Four hundred fifty-seven women with borderline ovarian tumor were analyzed.
Introduction: Approximately 2 to 5% of primary care consultations are patients with dyspepsia. One of the most controversial points among primary-care physicians and gastroenterologists is the diagnostic-therapeutic approach of the uninvestigated dyspeptic patient.
Aims And Methods: Our aim was to investigate prevalence of organic disease and Helicobacter pylori (Hp) status in uninvestigated dyspeptic out-patients at a primary-care level.
The West Indian Topshell Cittarium pica is artisanally collected on rocky shores along the Caribbean Coast of Costa Rica. There are neither data on the state of its exploitation nor exist any regulation of the fishery From October 2000 to March 2001, the population dynamics of this species were studied at an unexploited and two exploited sites to determine the present impact of the fishery on the resource. Average population density with 14 ind.
