As infants lose maternally derived antibody, they experience a period when antibody levels are insufficient to protect against measles yet may interfere with immunization. In Kangaba Mali, sera were collected from 89 2-8-month-old infants and 32 9-10-month-old infants without a history of measles or vaccination; post-vaccination sera were collected from 24 of the 9-10-month-old infants 3-5 week...

the future development of effective and safe antiretroviral agents—and the continued study of ways to maximize the utility of currently available therapies—are highly dependent on a scientific field that has evolved in recent years at an incredible rate: pharmacology. While The prn Notebook has published numerous articles focusing on the issues of pharmacokinetics (pk) and pharmacodynamics (pd)...

Up-to-date data are needed on the types of treatments used by psychiatrists and the reasons for use of particular treatments. Using 1997 American Psychiatric Association (APA) Practice Research Network (PRN) Study data on patients with schizophrenia and other psychotic disorders, we identified the characteristics of antipsychotic medications (APMs) currently being prescribed and factors associa...

We examined sensory-processing disorder (SPD) in children with cochlear implants and explored the relationship between SPD and duration of hearing loss or duration of cochlear implant use. Caregivers of 30 children completed the Sensory Profile Questionnaire (SPQ). Seventy percent of the children showed "at-risk" or "different" behaviors in one or more of five categories of the SPQ: auditory, v...

Neuroleptic malignant syndrome (NMS) is a rare life-threatening condition, usually induced by typical and atypical antipsychotics. A middle-aged woman with bipolar disorder and acute back pain due to multiple falls was admitted to the trauma ward of a general hospital. After 3 days, she suddenly developed signs and symptoms of NMS possibly caused by PRN injectable haloperidol, although the addi...

The article discusses various options for constructing binary generators of pseudo-random numbers (PRN) based on the so-called generalized Galois and Fibonacci matrices. terms "Galois matrix" "Fibonacci are borrowed from theory cryptography, in which linear feedback shift registers (LFSR) PRN according to schemes widely used. matrix generate identical sequences as LFSR generators. transition cl...

Tg(PrP-EGFP) mice express an enhanced green fluorescent protein (EGFP)-tagged version of the prion protein (PrP) that behaves like endogenous PrP in terms of its posttranslational processing, anatomical localization, and functional activity. In this study, we describe experiments in which Tg(PrP-EGFP) mice were inoculated intracerebrally with scrapie prions. Although PrP-EGFP was incapable of s...

Treatment regimes in adults Regardless of the treatment indication, there are essentially two regimes for administering anti-VEGF drugs: continuous and intermittent/as required (or pro re nata, PRN for short). Most of the initial trials were done as a continuous regime, with regular monthly injections over the course of 2 years, i.e. patients would have 24 injections in total. These trials show...
