Purpose: To determine the efficacy of community-based, culturally tailored exercise intervention on the moderate and vigorous physical activity and physiologic outcomes of low-income Latino women (Latinas).
Design: A randomized trial contrasted safety education to an aerobic dance intervention.
Setting: Interventions were held in a "store-front" exercise site near a community clinic.
The purpose of this study was to determine the validity of non-contact infrared thermometry to measure mean skin temperature in resting and exercising subjects in cold, thermo-neutral and hot environments. The subjects for the study were six healthy volunteers. Skin temperature was measured at three sites: the forearm, chest and calf on each subject using both contact thermistors and a non-contact infrared thermometer.

The purpose of this study was to determine the effect of active heat acclimation on the sweat osmolality and sweat sodium ion concentration vs. sweat rate relationship in humans. Eight healthy male volunteers completed 10 days of exercise in the heat.

SUMF1 is a glycosylated enzyme that is resident in the endoplasmic reticulum (ER), although it is also secreted. Here, we demonstrate that upon secretion, SUMF1 can be taken up from the medium by several cell lines.

Recent investigations have utilized the measurement of SA as an analog for respiratory muscle oxygenation. The purpose of this investigation was to examine the action of the serratus anterior via surface electromyography (EMG) and near infrared spectroscopy (NIRS) during exercise while controlling for muscular effort not related to ventilation.

The lactate threshold and onset of muscle deoxygenation were highly correlated under both conditions, and during the hypoxic condition both variables shifted leftward.

Methods And Results: Nineteen participants with well-controlled type 2 diabetes (sex: 11 M:8 F, age: 64+/-2 years, BMI: 28.9+/-1.
Small-for-size syndrome occurs in the presence of a reduced mass of liver that is insufficient to maintain normal liver function. It has been speculated that this dysfunction is principally associated with graft exposure to excessive portal perfusion. The aim of these cases was to evaluate the efficacy of octreotide, a splanchnic vasoconstrictor, and esmolol, a selective beta-blocker, to modify the portal perfusion in the postoperative phase after left living related liver transplantation (LRLT).

We tested trifluralin against Trypanosoma cruzi in a model of chronic Chagas disease in mice. CF1 mice (n=148) were intraperitoneally infected with 10(5) trypomastigotes of T. cruzi, H510C8C3 clone.

To explore this possibility and identify an efficacious ginseng for a longterm study, we conducted a preparation-finding study of different Korean red ginseng (KRG) root fractions followed by a dose-finding study of the most efficacious fraction.
Methods: A double-blind, randomized, within-subject design was used in both studies.
In glaucoma the retinal ganglion cells of the retina die through the induction of apoptosis leading to excavation of the optic nerve and blindness. Mutations in the optineurin (optic neuropathy inducing) protein were found associated with an adult form of glaucoma. To date, the role of optineurin in the neurodegeneration process that occurs during glaucoma is still unknown.

To evaluate this hypothesis, the serum iron response to an exercise-induced 1.5 degrees C rise in core body temperature was measured.

Seven elderly rest homes in Veneto Region of Northern Italy participated in the project, which was conducted on 144 cognitively intact elderly residents (97 females and 47 males). The participants were randomly divided into three groups: 48 subjects were given a canary, 43 subjects were given a plant, and 53 subjects were given nothing.

Purpose: Sodium bicarbonate was used to investigate the effect of blood pH on VO2 kinetics during heavy exercise.
Methods: On separate days, 10 active subjects performed two 6-min cycling bouts (208 +/- 12 W) at 25 W above their ventilatory threshold. Each subject ingested 0.
As part of a longitudinal study aimed at defining the natural history of prediabetic autoimmunity and predicting the risk of future cases of type 1 diabetes, 3607 newborns from three regions of continental Italy (Lombardia, Liguria, and Lazio) were subjected to genetic testing to determine human leukocyte antigen-DRB1 (HLA-DRB1) and -DQB1 allele and phenotype frequencies. Polymerase chain reaction and immobilized sequence-specific oligonucleotide probe assays were used to identify ten DRB1 allele lineages and three DQB1 alleles. No major inter-regional differences emerged in the allelic distribution indicating homogeneous distribution of the HLA DRB1-DQB1 alleles among the three regions analyzed.

Background: To develop a sensitive, specific screening strategy for predicting genetic risk for type 1 diabetes mellitus (T1DM) in the low-incidence continental Italian population, and to define with this tool, a cohort of high-to-moderate risk infants for an immunological follow-up study aimed at identifying environmental risk factors for T1DM.
Methods: 4855 newborns in three regions of continental Italy were screened for T1DM HLA-DRB1-DQB1 risk genotypes using a reverse line blot typing method. Risk classification was based on odds ratios (OR) found in a preliminary case-control study (356 T1DM patients, 412 controls).
It has previously been shown that extreme changes in ambient air temperature can affect whole-body bioelectrical impedance. The purpose of this study was to determine if more moderate changes in ambient air temperature, such as those experienced in most laboratory settings, would also affect bioelectric impedance analysis (BIA). In addition, to elucidate the mechanism responsible for changes in BIA with ambient air temperature, both skin blood flow (SBF) and the electrode-skin interface temperature were independently manipulated to determine their effect on BIA.

Measles outbreaks every 3-4 years have occurred in Argentina. The vaccine was introduced in 1978 as part of a regular program, and the age for the first vaccination was changed to one year old. The optimal age for first measles vaccination is defined as that age with the highest proportion of infants responding to the vaccine.
