Overview

What is she best known for?

The fields of study she is best known for:

  • Internal medicine
  • Enzyme
  • Immune system

The scientist’s investigation covers issues in Microbiology, Helicobacter pylori, Internal medicine, Helicobacter and Antiserum. Her study in Microbiology is interdisciplinary in nature, drawing from both Fimbria, Enterotoxigenic Escherichia coli, Hemagglutination and Virology. Her Helicobacter pylori research is multidisciplinary, incorporating perspectives in Bacterial adhesin, Immunomagnetic separation and 16S ribosomal RNA.

Her work deals with themes such as Gastroenterology and Metronidazole, which intersect with Internal medicine. Dolores G. Evans combines subjects such as Epidemiology, Gastritis, Immunology, Transmission and Asymptomatic with her study of Helicobacter. Dolores G. Evans interconnects Virulence factor and Escherichia coli Vaccines, Enterotoxin in the investigation of issues within Antiserum.

Her most cited work include:

  • Epidemiology of Helicobacter pylori in an asymptomatic population in the United States: Effect of age, race, and socioeconomic status (839 citations)
  • Epidemiology of Helicobacter pylori in an asymptomatic population in the United States: Effect of age, race, and socioeconomic status (839 citations)
  • EFFECT OF TREATMENT OF HELICOBACTER PYLORI INFECTION ON THE LONG-TERM RECURRENCE OF GASTRIC OR DUODENAL ULCER: A RANDOMIZED, CONTROLLED STUDY (813 citations)

What are the main themes of her work throughout her whole career to date?

Dolores G. Evans mainly investigates Microbiology, Enterotoxigenic Escherichia coli, Enterotoxin, Diarrhea and Internal medicine. The various areas that Dolores G. Evans examines in her Microbiology study include Antiserum, Antibody, Antigen and Virology. Her Enterotoxigenic Escherichia coli study integrates concerns from other disciplines, such as Fimbria and Hemagglutination.

Her Diarrhea research includes themes of Sulfamethoxazole, Immunology and Trimethoprim. Dolores G. Evans studies Helicobacter pylori, a branch of Internal medicine. Her research investigates the connection between Helicobacter and topics such as Urea breath test that intersect with problems in Epidemiology.

She most often published in these fields:

  • Microbiology (57.89%)
  • Enterotoxigenic Escherichia coli (31.58%)
  • Enterotoxin (28.07%)

What were the highlights of her more recent work (between 1991-2020)?

  • Gastroenterology (33.33%)
  • Internal medicine (43.86%)
  • Helicobacter pylori (36.84%)

In recent papers she was focusing on the following fields of study:

Her primary scientific interests are in Gastroenterology, Internal medicine, Helicobacter pylori, Helicobacter pylori infection and Duodenal ulcer. Her Gastroenterology research is multidisciplinary, relying on both Randomized controlled trial, Asymptomatic and Pathology. Her Randomized controlled trial research is multidisciplinary, incorporating elements of Ranitidine, Chemotherapy, Bismuth subsalicylate, Endoscopy and Veterans Affairs.

Her work on Gastritis and Duodenum as part of her general Internal medicine study is frequently connected to DNA–DNA hybridization and Peptic, thereby bridging the divide between different branches of science. Her Helicobacter pylori research incorporates themes from GroEL, Microbiology and Biochemistry. The study incorporates disciplines such as Bacterial adhesin and 16S ribosomal RNA in addition to Microbiology.

Between 1991 and 2020, her most popular works were:

  • EFFECT OF TREATMENT OF HELICOBACTER PYLORI INFECTION ON THE LONG-TERM RECURRENCE OF GASTRIC OR DUODENAL ULCER: A RANDOMIZED, CONTROLLED STUDY (813 citations)
  • Characterization of a Helicobacter pylori neutrophil-activating protein. (267 citations)
  • Helicobacter pylori in the drinking water in Peru. (266 citations)

In her most recent research, the most cited papers focused on:

  • Internal medicine
  • Enzyme
  • Immune system

Dolores G. Evans mostly deals with Helicobacter pylori, Microbiology, Bacterial adhesin, Immunomagnetic separation and Ribosomal RNA. Her Helicobacter pylori research is mostly focused on the topic Helicobacter. The Microbiology study combines topics in areas such as CD18 and In vitro.

In her research, Dolores G. Evans undertakes multidisciplinary study on Bacterial adhesin and Reverse transcriptase.
