Cilia beat to an unexpected rhythm in male reproductive tract, study in mice reveals

Waves of undulating cilia drive several processes essential to life. They clear debris and mucus from the respiratory tract, move spinal fluid through the brain and transport embryos from the ovaries to the uterus for implantation. According to a new study in mice, however, cilia perform somewhat differently in the male reproductive tract.

Discovery: Mechanical properties of viral DNA determine the course of infection

A new study reveals a previously unknown mechanism that governs whether viruses that infect bacteria will quickly kill their hosts or remain latent inside the cell. The discovery, reported in the journal eLife, also may apply to viruses that infect humans and other animals, the researcher said.

Study explores risk factors linked to chikungunya and dengue outbreaks

In one of the largest studies of its kind, researchers analyzed chikungunya and dengue outbreak data from 76 countries over a period of 50 years, focusing on regions across the Indian Ocean that are hard hit by these and other mosquito-borne infectious diseases.

Products of omega-3 fatty acid metabolism may have anticancer effects, study shows

A class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer’s growth and spread, University of Illinois researchers report in a new study in mice.

Cancer drug starts clinical trials in human brain-cancer patients

A drug that spurs cancer cells to self-destruct has been cleared for use in a clinical trial of patients with anaplastic astrocytoma, a rare malignant brain tumor, and glioblastoma multiforme, an aggressive late-stage cancer of the brain. This phase Ib trial will determine if the experimental drug PAC-1 can be used safely in combination with a standard brain-cancer chemotherapy drug, temozolomide.

Study in mice finds dietary levels of genistein may adversely affect female fertility

Exposure to the phytoestrogen genistein prior to conception may adversely affect female fertility and pregnancy outcomes, depending on the dosage and duration of exposure, a new study in mice by scientists at the University of Illinois suggests.

Antibiotic-resistant infections in pets: What now?

Rates of antibiotic-resistant infections in companion animals are rising at an alarming rate. An Illinois veterinarian discusses what can be done about it.

Paper: Clinical signs best predictors of mortality in critically ill calves

Clinical signs may be better predictors of mortality in neonatal calves with diarrhea than blood pH levels and other laboratory findings, suggests a new study co-written by University of Illinois researcher Peter D. Constable.
