In the recent past, Caenorhabditis elegans has emerged as one of the leading nematode models for studying host-microbe interactions on molecular, cellular, or organismal levels. In general, morphological and functional similarities of the gut of C. elegans with respect to that of human has brought in speculations on the study of the intestinal microbiota.

Transcription factors use a DNA-binding domain to localize their action and a transactivation domain (tAD) to stimulate activation of the associated gene. Recent work has renewed interest in how tADs activate genes, which remains poorly understood. Key features in the new models are exposure of short linear motifs (SLMs) and liquid-liquid phase separation (LLPS).

Hit, Lead & Candidate Discovery A variety of novel 2-(methyl/phenyl)-3-(4-(5-substituted-1,3,4-oxadiazol-2-yl)phenyl) quinazolin-4(3H)-ones have been synthesized by treating 3-(4-(5-mercapto-1,3,4-oxadiazol-2-yl)phenyl)-2-(methyl/phenyl)-quinazolin-4(3H)-one with a variety of secondary amines. Graph theoretical analysis was used in identification of drug target that is, NMDAR (N-methyl-d-aspartate receptors). The observed reports of in silico modeling and ligand based toxicity, metabolism prediction studies were encouraging us to synthesize of title compounds and evaluate their antiepileptic effects.

Objectives: To evaluate the trends in glucocorticoid (GC) therapy in patients with giant cell arteritis (GCA).

Methods: Using a population-based inception cohort, GC therapy details were collected for all patients with GCA diagnosed between 1950-2009. GC usage for patients diagnosed with GCA between 1980-2009 was compared to those diagnosed between 1950-1979.

Objective: To assess the incidence of giant cell arteritis (GCA) in the era from 2000 to 2009.

Method: We extended the previously identified population-based cohort of Olmsted County, Minnesota residents who fulfilled 1990 American College of Rheumatology (ACR) criteria for GCA for earlier decades during 1950-1999.

Results: In 2000-2009, 74 cases of GCA were identified (mean age 78.

Objective: To assess the occurrence of infections requiring or acquired during hospitalization in patients with giant cell arteritis (GCA).

Methods: We retrospectively reviewed a population-based incidence cohort of patients with GCA diagnosed between 1950 and 2009 and compared this cohort with a non-GCA one matched for age, sex, and calendar year from the same population.

Results: We identified 245 patients in the GCA cohort and 245 patients in the non-GCA cohort.

Objective: To assess the occurrence of acute coronary syndrome (ACS) in patients with giant cell arteritis (GCA) compared to subjects without GCA.

Methods: We retrospectively reviewed a population-based incidence cohort of Olmsted County, Minnesota residents with GCA diagnosed in 1950-2009. We compared this cohort with a cohort of patients without GCA of similar age, sex, and calendar year from the same population.

Anesthetic management of a patient with tracheal stenosis is challenging. Though we have newer imaging modalities like multislice, three-dimensional computerized tomography, virtual bronchoscopy to determine the size and anatomy of the airway, it is difficult to accurately predict the distensibility of the trachea with the available preoperative tests. With our experience in this case, we believe that newer imaging modalities are just an adjunct in the assessment of the compromised airway in case of dynamic compression.

Objective: To assess the occurrence, risk factors, morbidity, and mortality associated with lower extremity (LE) ulcers in patients with rheumatoid arthritis (RA).

Methods: Retrospective review of Olmsted County, Minnesota, USA, residents who first fulfilled the 1987 American College of Rheumatology criteria for RA in 1980-2007 with followup to death, migration, or April 2012. Only LE ulcers that developed after the diagnosis of RA were included.

Takayasu arteritis is a rare, chronic form of large vessel vasculitis that characteristically involves the aorta and its branches. Its origin and disease process are currently unknown, although T lymphocytes and, most recently, B cells are thought to play a role. Common variable immunodeficiency (CVID) is a collection of heterogeneous disorders resulting in an antibody deficiency and recurrent infections, and is the most common symptomatic primary immunodeficiency disorder.
