The ion exchange resin Amberlite 958 was used to investigate its behaviour on the removal of hazardous vanadium(V) from aqueous media. This investigation carried out under various hydrodynamic conditions and chemical conditions, such as variation stirring speed, pH solution, dosage, initial in temperature. Vanadium(V) uptake onto highly dependent thus, speciation this phase; process had an endo...

Organic fertilizers have been used in agriculture to improve soil fertility, promote plant growth and protection which improves crop productivity. A field experiment was conducted order study the effect of organic (compost its water extract) on yield barley production. The results achieved showed that either compost (T3) or dual application with extract (T4) as biofertilizers increased most par...

The purpose was to determine the aerobic power (maximal oxygen uptake) and body composition of older track athletes after a 20-yr follow-up (T3). At 20 yr, 21 subjects [mean ages: 50.5 +/- 8.5 yr at initial evaluation (T1), 60.2 +/- 8.8 yr at 10-yr follow-up (T2), and 70.4 +/- 8.8 yr at 20-yr follow-up (T3)] were divided into three intensity groups: high (H; remained elite; n = 9); moderate (M;...

Changes in TSH secretion in six acromegalic patients were studied before and after transsphenoidal adenomectomy (Hardy's method) and compared to normal subjects and six patients with prolactinoma. Basal serum GH levels ranging from 5 to over 250 ng/ml before adenomectomy decreased to below 5 ng/ml after the operation, and the abnormal responses of GH to TRH observed initially in three of the si...

a chelating resin is prepared by condensation polymerization of aniline with formaldehyde andcharacterized by ft-ir, elemental analysis and studied for the preconcentration and determination of traceplatinum ion from environmental water sample using inductively coupled plasma-atomic emission spectroscopy(icp-aes). the optimum ph value for sorption of the metal ions was 5. the maximum adsorption...

The objective of this study was to determine the effects of milk supplemented with Sel-Plex on thyroid hormones, rectal temperature, plasma glucose and cholesterol concentrations, and body weight in suckling calves. Ten Holstein suckling male calves of approximately 1 month of age were selected and randomly allocated to one of two groups and fed either unsupplemented milk (control) or milk supp...

Saturable, high-affinity binding sites for 3,5,3'-triiodo-u-thyronine (T3) were identified in isolated nuclei and solubilized chromatin extracts of mammary glands, spontaneous mam mary tumors, and liver from C3H/HeN mice. Receptor concen tration in whole mammary gland nuclei (254 fmol/mg DMA) was only about one-half that of mouse liver nuclei (536 fmol/ mg DNA), but in molecular weight (55,000)...

Recombinant human thyroid-stimulating hormone (rhTSH) enhances 131I uptake, permitting a decrease in radiation for the treatment of multinodular goiter (MNG). Our objective was to evaluate the safety and efficacy of a single 0.1-mg dose of rhTSH, followed by 30 mCi 131I, in patients with MNG. Seventeen patients (15 females, 59.0 +/- 13.1 years), who had never been submitted to 131I therapy, rec...

This very inexpensive method of estimating T(3) uptake, already described (Walther, 1971), uses only 0.1 ml of patient's serum and discriminates between thyrotoxicosis and myxoedema much better than the resin sponge method. It can readily be mechanized and the ;free thyroxine index' derived has normal limits of 3.0 to 8.0.
