Identifying the sex chromosome and sex determination genes in the cattle tick, Rhipicephalus (Boophilus) microplus.

Rhipicephalus (Boophilus) microplus is globally one of the most economically important ectoparasites of cattle costing the agriculture industry billions of dollars annually. Resistance to chemical control measures has prompted the development of novel methods of control. Recent advancements in genetic control measures for human and other animal vectors have utilized sex determination research to manipulate sex ratios, which have shown promising results in mosquitoes namely Aedes aegypti and Anopheles stephensi.

Beyond the Norm: Acute Multifocal Diverticulitis.

Colonic diverticulitis is inflammation of diverticula, which are sac-like protrusions in the colonic wall. It is thought that increased intraluminal pressure and trapped food leads to inflammation. Newer theories suggest that alterations in the gut microbiome and chronic inflammation play a role as well.

A new record of fleas from nilgai antelope in southern Texas and fleas from other wildlife.

Wildlife are hosts of ectoparasites, such as fleas and ticks that may transmit human and animal pathogens. Little is known about the ecology of many ectoparasite species native to southern Texas, or their role in pathogen maintenance and transmission. Much attention has been given to the role of nonnative nilgai antelope as cattle fever tick hosts and agents of dispersal, but little attention has been given to other ectoparasites that may utilize nilgai antelope as hosts.

The Clinical Nurse Specialist: Maximizing Return on Investment.

The United States health care system is facing an unprecedented nursing shortage, increasing complexity of care, and fewer experienced nurse mentors. These factors contribute to a cycle of burnout, turnover, decreased quality and safety, and a worsening financial bottom line. Improving these contributing factors depends on our ability to mitigate the structural causes of burnout and turnover.
