A 53-year-old man with a noncontributory medical history presented to the hospital with blurry vision, intermittently blue fingers, and slowly progressive dyspnea. Blood test results showed the following: hematocrit, 16% (reference interval, 40%–51%); white blood cells, 15.5 10/ L (reference interval, 4.2 10/ L to 9.1 10/ L); platelet count, 50 10/ L (reference interval, 150 10/ L to 330 10/ L)...

Abstract Objective: Homeostasis model assessment of insulin resistance (HOMA-IR) is a simple and practical method for estimation of insulin resistance (IR), but a reliable reference interval (RI) of HOMA-IR is needed to deduce the threshold level to define IR. This RI has been controversial in different populations and even more divergent when considering factors like age, gender and body mass...

objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...

BACKGROUND Examination of the 2-dimensional probability distribution of thyroid-stimulating hormone (TSH) and free thyroxine (FT(4)) shows that the widths of the TSH and FT(4) reference intervals derived from this bivariate distribution are mutually interdependent, an aspect commonly ignored when interpreting thyroid testing results with separate reference intervals for TSH and FT(4). We desire...

BACKGROUND Insufficient function of the thyroid gland can cause low concentrations of thyroid gland hormones which are necessary for the proper development of the foetus brain, especially during the beginning of pregnancy. We determined the reference interval for TSH in the first trimester of pregnancy and the decision point for anti-TPO antibodies' positivity. METHODS We tested 5520 women fr...

it is firstly proved that the multi-input-single-output (miso) fuzzy systems based on interval-valued $r$- and $s$-implications can approximate any continuous function defined on a compact set to arbitrary accuracy.  a formula to compute the lower upper bounds on the number  of interval-valued fuzzy sets needed to achieve a pre-specified approximation  accuracy for an arbitrary multivariate con...
