Abstract	Soil salinization and sodification, caused by inadequate land management, is one of the main threats to the semiarid agroecosystems. It is essential to investigate saline levels under different land-use conditions to maintain the sustainability of agricultural production. The main objective of this study was to diagnose the salinity status of the soil in different land-use conditions in the semiarid region of Northeast Brazil. Soil samples were collected in the surface layer (0–5 cm) of three different land-use conditions: areas of low salinity (native vegetation – Caatinga), areas of different saline levels (cultivated areas), and areas of very high salinity (desertified by salinity), and compared regarding the chemical attributes of the soils by descriptive and multivariate analysis. The results showed that sodium and chloride were the predominant soluble ions in cultivated and desertified areas due to saline waters commonly used in the study region. Increases in electrical conductivity values of 1219 and 23207% were observed for cultivated and desertified areas, respectively, compared to areas of native vegetation. The principal component analysis contributed to identifying parameters responsible for the variation in soil salinity, and the second factor identified that percentage of exchangeable sodium, electrical conductivity, and exchangeable and soluble sodium plays an essential role in soil desertification. However, calcium, magnesium, sodium, and chloride ions correlated positively with variables that degrade soils - EC, ESP, and SAR. We also found that in desertified areas, in addition to chloride, sulfate is also present in expressive levels, and due to the strong associations with calcium, magnesium, and sodium, our study suggests that in addition to the free forms of these ions, the forms of chlorides and sulfates of calcium, magnesium, and sodium also effectively contribute to the degradation of the areas. The combination of multivariate analysis × geochemistry × laboratory techniques was a valuable ...

Abstract	An alternative to the TNM classification system has been proposed for patients with head and neck cancer. The T and N integer score (TANIS) system adds the integer values of T and N classifications. The TNM and TANIS staging systems were retrospectively evaluated for 186 patients with squamous cell carcinoma of the oral cavity (tongue and floor of mouth). The TANIS system was found to better separate the patients into prognostic groups and allowed a more accurate prediction of disease-free survival.

Article: Activation of D1 and D2 dopamine receptors inhibits protein kinase C activity in striatal synaptoneurosomes.

Giambalvo, C T / Wagner, R L

Abstract	The effects of D1 and D2 dopamine ligands on protein kinase C (PKC) activity were examined in synaptoneurosomes. Incubation with D1 agonists (SKF 38393, fenodopam), in the presence of calcium, decreased the soluble and increased the particulate PKC activity. These effects were reversed by SCH 23390, which by itself had the opposite effect of increasing the soluble and decreasing the particulate PKC activity. In contrast, incubation with the D2 agonists [LY 171555, (+)-3-(3-hydroxyphenyl)-N-n-propylpiperidine, RU 24213] increased the soluble and decreased the particulate PKC activity. These effects were reversed by sulpiride. (-)-3-(3-Hydroxyphenyl)-N-n-propylpiperidine had a D2 antagonist profile. Apomorphine showed a biphasic dose-response change; i.e., it decreased particulate PKC activity at the D2 receptor at low concentrations (0.1 microM) and increased it at the D1 receptor at higher concentrations (10 microM). Pretreatment with tetrodotoxin or omission of calcium in the incubation medium did not alter the responses of the D2 agonists, but it reversed the changes in PKC activity induced by the D1 agonists and converted the biphasic response of apomorphine to a monophasic inhibition. These results indicate that (1)D1 and D2 dopamine receptors are negatively coupled to PKC and (2) the increase in particulate PKC activity seen with the D1 drugs in the presence of calcium is mediated indirectly via a transneuronal effect.

Abstract	The authors present a study in which 33 chronic schizophrenic patients who, when withdrawn from antipsychotic drug treatment for more than 2 weeks, presented with concurrent signs of akathisia and tardive dyskinesia; however, signs of akinesia, facial masking, rigidity, or dystonia were not concurrent with the patients' akathetic presentation. In a subsequent study phase, these patients were treated with antipsychotics for up to 6 weeks. The dyskinetic signs that had been dramatically more severe in those patients exhibiting akathisia following withdrawal from antipsychotic medication continued for up to 6 weeks following the renewal of antipsychotic drug therapy. These findings help to confirm a relationship between tardive dyskinesia and a persistent akathisia of later onset known as tardive akathisia.

Abstract	Background: Extracapsular spread (ECS) of cervical lymph node metastases of squamous cell carcinoma from head and neck sites portend poor prognosis. Therefore, a program of combined surgery, postoperative irradiation therapy, and adjuvant methotrexate and 5-fluorouracil (5-FU) was initiated in 1982 for such patients. Method: All patients operated on between June 1982 and December 1992 by the full-time faculty of the Department of Otolaryngology at the University of Pittsburgh School of Medicine were eligible and reported in this trial. All patients had negative surgical margins of excision of the primary carcinoma, and histologic evidence of cervical metastases with ECS. Postoperative irradiation included 50-60 cGy for 5 to 6 weeks followed by methotrexate and 5-FU administered on an outpatient basis on days 1 and 8 every 21 days. All patients were followed for 30 or more months for evidence of recurrent disease. Result: A total of 371 patients met eligibility criteria. Of this group, 53 (14%) were treated with surgery only, 187 (50%) received surgery and postoperative irradiation, and 131 (35%) received surgery, irradiation therapy, and chemotherapy. The primary site, extent of nodal involvement, and stage of the three patient groups were similar. However, performance status (Karnofsky) was best in the patients who received chemoradiation (average 90) when compared with those who received surgery and irradiation (average 80) or surgery only (average 70). Absolute disease free survival rate (30 months) was 9.5% in patients treated with surgery only, 34% in patients treated with surgery plus irradiation, and 53% in patients treated with surgery, irradiation, and chemotherapy. When adjusted for patients who died of intercurrent disease with less than 30 months follow-up, survival rates became 17%, 40%, and 58%, respectively. These differences are highly significant (P < 0.001). Conclusion: Results of this study suggest that postoperative chemoradiation may improve survival in patients with ECS of cervical metastases. Compliance with the chemoradiation was suboptimal and suggests that improved strategy must be developed.
