Impact of Maternal Immunity on Congenital Cytomegalovirus Birth Prevalence and Infant Outcomes: A Systematic Review.

Congenital cytomegalovirus (cCMV) is the leading non-genetic cause of sensorineural hearing loss (SNHL), and efforts are geared towards prevention through vaccine development. Transmission rates following primary maternal infection occur at rates of 30-40%, however reported placental rates upon non-primary maternal infection is reported to be less than <4%. There is significant debate about whether this reduction in transmission rate is due to pre-existing maternal immunity, which could identify possible immunologic targets for vaccines.

A case report of mevalonate kinase deficiency in a 14-month-old female with fevers and lower extremity weakness.

Background: This case follows a 14-month-old female, who despite multiple presentations to several physicians, continued to have recurrent febrile episodes with gross motor delay. Her case revealed an often missed diagnosis of Mevalonate Kinase Deficiency, that now has an FDA approved treatment that both reduces recurrence and produces remission.

Case Presentation: A 14-month-old female with a history of gross motor delay, frequent Upper Respiratory Tract infections, and otitis media presented to an urgent care for inconsolability and refusal to bear weight on her right leg.

Failure of intravenous or intracardiac delivery of mesenchymal stromal cells to improve outcomes after focal traumatic brain injury in the female rat.

Mesenchymal stromal cells secrete a variety of anti-inflammatory factors and may provide a regenerative medicine option for the treatment of traumatic brain injury. The present study investigates the efficacy of multiple intravenous or intracardiac administrations of rat mesenchymal stromal cells or human mesenchymal stromal cells in female rats after controlled cortical impact by in vivo MRI, neurobehavior, and histopathology evaluation. Neither intravenous nor intracardiac administration of mesenchymal stromal cells derived from either rats or humans improved MRI measures of lesion volume or neurobehavioral outcome compared to saline treatment.

Self-assembling nanocomplexes by combining ferumoxytol, heparin and protamine for cell tracking by magnetic resonance imaging.

We report on a new straightforward magnetic cell-labeling approach that combines three US Food and Drug Administration (FDA)-approved drugs--ferumoxytol, heparin and protamine--in serum-free medium to form self-assembling nanocomplexes that effectively label cells for in vivo magnetic resonance imaging (MRI). We observed that the ferumoxytol-heparin-protamine (HPF) nanocomplexes were stable in serum-free cell culture medium. HPF nanocomplexes show a threefold increase in T2 relaxivity compared to ferumoxytol.

Pyrene degradation and detoxification in soil by a consortium of basidiomycetes isolated from compost: role of laccases and peroxidases.

A consortium of three basidiomycetes isolated from compost was investigated for pyrene degradation in soil microcosms. Pyrene concentration, glucose and ammonium evolution, moisture content, ligninolytic enzyme activities and phytotoxicity (germination index) on Lepidium sativum L. seeds were monitored.
