Sixty-nine males aged 18-57 years, who had different impaired reproductive function and the body mass index (BMI) in the range of 20 to 40 kg/m2, were examined. In the patients, the baseline values of leptin, cortisole, corticosterone, dehydroepiandrosterone (DHA) and dehydroepiandrosterone sulfate (DHAS), progesterone, 17-hydroxyprogesterone, testosterone, and insulin were measured by using current radioimmunoassay and enzyme immunoassay. In the examinees, the mean values of all the hormones varied in the physiological normal range with deviations being in some patients. The patients with higher leptin levels were found to have also elevated adrenal hormones, such as corticosterone, cortisole, DHA and DHAS vice versa. This was not accompanied by differences in BMI and in the levels of insulin and testosterone. Analysis of the content of hormones in relation to the level of insulin indicated that there is a positive correlation of the level of insulin and leptin. However, this relationship was multifactorial, which had a possible modifying effects of BMI and the level of testosterone.

The biochemical blood parameters characterizing the students ’nutritional status were evaluated: protein, lipid, carbohydrate metabolism, a number of minerals. The mean values, errors of the mean, median (Me), boundary (Q) and the range of 25–75 percentiles were determined. In 9.1 % of students and 28.6 % of students, the total protein was increased. Creatinine in men was in the upper normal range, in women — at the upper limit of normal, of which 46.2 % was higher than normal. The interval Q25–75 of uric acid in students is determined in the lower normal zone. In 40.0 % of men, decreased high-density lipoprotein cholesterol (Q25–75 corresponded to 1.15–1.79), in women — below normal, Q25–75 5 was 1.3–1.5, decreased in 73.3 %. Me and Q25–75 iron were in the lower normal range; 14.1 % of men and 13.2 % of women are below normal. Me sodium and potassium at the level of the lower boundary of the norm, Q25–75 in the lower zone of the norm: in 16.0 % and 15.4 % of students the levels are reduced. Calcium is slightly above the lower limit of the norm, Q25–75–2.1–2.24, indicating an insufficient intake in the whole group; 25.0 % are below normal. The border of the 25th percentile of magnesium is at the level of the lower border of the norm, in 19.2 % it is reduced. 7.2 % lack of chlorine. Phosphorus is normal, but Q25–75 is in the upper zone; 17.9 % increased. Biochemical markers can identify individuals with metabolic disorders of nutrients. Statistical indicators — the median, the boundaries of 25–75 quartiles and their scope characterize the metabolism of macronutrients and minerals in the group and subgroups of students. Laboratory and mathematical methods can provide a basis for identifying the specific causes of these changes. For this, you can use the questionnaire method of studying the nutrition of students, possibly using the developed questionnaires for a specific situation.

Abstract A method for the determination of serum arginase is given which combines the enzymatic formation of urea with the sensitive method of Coulombe (1) for measuring this substance. This procedure allows more accurate determinations in the normal range than do previous methods described and is convenient for clinical routine. Significant difference is found between the mean values of normal men and women, 3.9 units/L. for the former and 2.9 units/L. for the latter.

Source Of Information

A longitudinal study of urinary 17-OHCS in 16 depressive patients showed mean values within the accepted normal range. There were no significant differences between pre-treatment and post-treatment values; only the female patients showed a tendency to have somewhat lower post-treatment levels. 17-KS output was measured in 18 depressive patients. The mean values were within the normal range. There was no significant difference between pre-treatment and post-treatment values although the female patients displayed a tendency towards somewhat lower levels following treatment. DHA and EA excretion were measured in 9 depressive patients. There was a very wide variance in the findings. There was no significant difference between pre-treatment and post-treatment levels. The significance of the above findings is discussed. It is considered that measurements of urinary excretion of corticosteroids in affective disorders constitute a limited source of information.

Eight adult Soay rams (four control and four cranially sympathectomized by removal of the superior cervical ganglia) were exposed to alternating 16-week periods of short days of 8 h light: 16 h darkness (8L : 16D) and long days (16L : 8D) for more than 3 years, and the changes in the diameter of the testes were recorded. Once during short days and once during long days blood samples were collected hourly for 28 h, and the concentrations of melatonin, prolactin, FSH, LH, testosterone, tri-iodothyronine (T3), thyroxine (T4) and cortisol were measured by radioimmunoassay. In the control rams the testes were reduced in size during long days compared to short days, and the blood concentrations (24-h mean values) of FSH, LH and testosterone were decreased. The levels of prolactin were much increased, while there was no significant change in the mean levels of melatonin, T3, T4 and cortisol. During both photoperiods there was considerable hour-to-hour variation in all eight hormones indicative of episodic secretion, as well as a consistent variation related to the time of day which was most pronounced for melatonin and T3. There was a clear difference in the daily profile of plasma melatonin levels between short and long days. In the superior cervical ganglionectomized rams there were no significant changes in the size of the testes or in the hormone titres between short and long days. Compared to the controls the plasma levels of LH, FSH, testosterone and prolactin were in the intermediate range. Some consistent diurnal variation was evident in the levels of all the hormones measured, with a pattern similar to the controls for a few of the hormones (e.g. T3) but quite different for others (e.g. melatonin).

Objective: Most cases of hypophosphatasia (HPP) exhibit early loss of primary teeth. Results of micro-computed tomography (micro-CT) analysis of teeth with HPP have not yet been reported. The purpose of the present study was to describe the size and mineral density distribution and mapping of exfoliated teeth with HPP using micro CT. Study design: Seven exfoliated teeth were obtained from a patient with HPP. Exfoliated teeth sizes were measured on micro CT images and mineral densities of the mandibular primary central incisors were determined. Results: Partial dentures were fabricated for the patient to replace the eight primary teeth which had exfoliated. Most primary teeth sizes were within the normal range. The mean values of enamel and dentin mineral densities in teeth with HPP were 1.35 and 0.88 g/cm3, respectively, in the mandibular primary central incisors. Conclusion: Mineral density distribution and mapping revealed that the values in teeth with HPP were lower than the homonymous teeth controls in all regions from the crown to apex. Furthermore, it was demonstrated that the differences between HPP and controls were larger on the crown side and the differences tended to converge on the apex side. These results suggested that the present patient showed mild hypomineralization in the primary dentition.

In recent times there have been advances in the management of Human Immunodeficiency Virus infection. However, the disease still poses threat to biochemical parameters of the body. This study was carried out to investigate the biochemical parameters in Human Immunodeficiency Virus infected patients who were yet to start anti-Retroviral drugs regimen. This study was carried out for a period of six weeks using structural questionnaires.  A total of one hundred participants were used for the study out of which fifty were Human Immunodeficiency Virus infected while the remaining fifty were Human Immunodeficiency Virus negative, who served as control. There were significant differences (p<0.05) in the values of Total Protein, Albumin, Alkaline Phosphatase, Aspartate aminotransferase, Alanine aminotransferase, Total Cholesterol, High Density Lipoprotein Cholesterol, Triacylglycerol, Calcium and Sodium of Human Immunodeficiency Virus positive patients when compared with the control. However, there were no significant differences (p>0.05) between the mean values of the conjugated Bilirubin, Urea, Creatinine, Potassium, Bicarbonate and Chloride of the infected patients when compared with those of the control. The findings in this study showed significant changes in biochemical parameters in Human Immunodeficiency Virus infected subjects.

An asymptotic study is made of potential and tree-surface elevation due to forward motion of a submerged body with an oscillating velocity. The latter is supposed to be a short period. As the nondimensional period ε 1, the singular perturbation technique is applied. Using two-term expansion for the potential, the principal terms of asymptotics for instant and mean values of wave resistance are obtained. The mean value (up to a term 0(e)) is the sum of two addends, the first of which is the wave resistance of the same body moving at the mean speed. The second addend is proportional to the dispersion of velocity with the coefficient depending on the form of the body. This coefficient vanishes if the body is symmetric with respect to the mid-section. Numerical examples for the two-dimensional problem show that there exist cylinders with the following property: the absolute value of wave resistance decreases when passing from motion at the mean speed to motion with oscillating velocity.

The ability of children with cyanotic breath-holding spells to respond to anger or frustration by voluntary breath-holding for prolonged periods (often to the point of precipitating hypoxic seizure activity) suggested the hypothesis that such children may have a less powerful urge to breathe in the presence of hypoxia and/or hypercapnia than children who do not have breath-holding spells. Because ventilatory chemosensitivity is difficult to measure in infants and young children, this hypothesis was tested indirectly by measuring the ventilatory responses to hyperoxic progressive hypercapnia and to isocapnic progressive hypoxia of seven individuals who had a history of cyanotic breath-holding spells in infancy and 17 control subjects. The mean values for sensitivity to hypoxia and to hypercapnia were not significantly different between the two groups, and the responses of the majority of the subjects with cyanotic breath-holding spells were clearly within the normal range. There were fewer individuals with high-normal ventilatory responses among the subjects with cyanotic breath-holding spells. Although children with cyanotic breath-holding spells may have decreased ventilatory chemosensitivity transiently during infancy or may differ from other children in some other aspect of the control of breathing, the pathogenesis of infantile cyanotic breath-holding spells does not involve a permanently blunted sensitivity to hypercapnia or hypoxia.
