Abstract
CONTEXT It is important to address fatigue and co-occurring symptoms during chemotherapy to preserve quality of life in patients with gastrointestinal (GI) cancer. OBJECTIVE To conduct a randomized controlled pilot study of a Yoga Skills Training (YST) intervention compared to an attention control (AC) among adults diagnosed with GI cancer. METHODS YST consisted of four 30-minute sessions delivered individually during chemotherapy plus home practice. AC provided empathic attention plus home diaries. Patient-reported (PROMIS T-score) assessments of fatigue, depressive symptoms, sleep disturbances, and psychological stress (Perceived Stress Scale) were collected at chemotherapy visits: baseline, Week 8, Week 10 and Week 14, and analyzed using a mixed effects model. Inflammatory cytokines were assessed at baseline and Week 10. RESULTS Forty-four of 77 adults approached agreed to participate (57%; YST n = 23; AC n = 21). Participants' mean age was 58 years and 48% were men. Participants randomized to YST reported a larger decline in fatigue (-2.4 difference, d = 0.30) and depressive symptoms (-2.5 difference, d = 0.30) than AC participants from baseline to Week 10 and sleep disturbances at Week 8 (-3.9 difference, d = 0.50). Differences in magnitude of change in symptoms were consistent with or exceeded a minimally important difference. Psychological stress decreased more in the AC at Week 10 (d = 0.30). Reductions in inflammatory cytokines (IL-6, sTNF R1) were larger in the YST group than AC. CONCLUSION YST showed promise for improving fatigue, depressive symptoms, sleep disturbances, and inflammation. YST is also feasible and reaches patients underrepresented in yoga research (i.e., GI cancer, men), thus warranting further examination.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The leaves of Persea americana Mill. (Lauraceae) have been popularly used in the treatment of diabetes in countries in Latin America and Africa. AIM OF THE STUDY To investigate the hypoglycaemic properties and to determine the molecular mechanism by which the hydroalcoholic extract of the leaves of Persea americana reduce blood glucose levels in streptozotocin (STZ)-induced diabetes in rats via the enzymatic pathway of protein kinase B (PKB/Akt). METHODS The hydroalcoholic extract of the leaves of Persea americana (0.15 and 0.3g/kg/day), vehicle and metformin (0.5g/kg/day) were administered orally to STZ-diabetic rats (n=7/group) for 4 weeks. Changes in body weight, food and water intake, fasting glucose levels and oral glucose tolerance were evaluated. Phosphorylation and the expression of PKB in the liver and soleus muscle were determined by Western blot. RESULTS The hydroalcoholic extract of the leaves of Persea americana reduced blood glucose levels and improved the metabolic state of the animals. Additionally, PKB activation was observed in the liver and skeletal muscle of treated rats when compared with untreated rats. CONCLUSION The results indicate that the hydroalcoholic extract of the leaves of Persea americana has anti-diabetic properties and possibly acts to regulate glucose uptake in liver and muscles by way of PKB/Akt activation, restoring the intracellular energy balance.

Abstract
Carapa guianensis (Meliaceae), known as Andiroba in Brazil, has been used by Amazon Rainforest indigenous communities for treatment of coughs, convulsions, skin diseases, arthritis, rheumatism, ear infections, to heal wounds and bruises and as an insect repellent. Carapa guianensis seed oil (SO) was evaluated for its acute and subacute toxicity (30 days) by the oral route in Wistar rats. In the acute toxicity test, SO (0.625-5.0g/kg, n=5/sex) did not produce any hazardous symptoms or deaths. The subacute treatment with SO (0.375, 0.75 and 1.5g/kg, n=10/group) failed to change body weight gain, food and water consumption. Hematological analysis showed no significant differences in any of the parameters examined. However, in the biochemical parameters, there was an increase in the alanine aminotransferase (ALT) serum level (29%) in the group SO 1.5g/kg. In addition, absolute and relative liver weights were increased at the doses of 0.75g/kg (23.4 and 19.1%) and 1.5g/kg (18.7 and 33.1%). In conclusion, acute and subacute administration of Carapa guianensis seed oil did not produce toxic effects in male Wistar rats. However, the increase in the ALT serum level and in both absolute and relative liver weights may indicate a possible hepatic toxicity.

Abstract
The effects of the administration of Carapa guianensis Aublet (Meliaceae) seed oil were investigated during pregnancy in female Wistar rats. Five groups of pregnant rats (n=5-9 per group) were treated orally from the 7th to the 14th day of pregnancy (organogenic period), at doses of: 0, 0.375, 0.75, 1.5 and 3.0gkg(-1). On the 20th day of pregnancy, the animals were sacrificed and laparotomized to evaluate reproductive parameters. The results showed that there was no difference between the control and treated groups in terms of the number of live and dead fetuses, the dam-offspring relationship, the weight of the fetus, the weight of the placentae and ovaries, the number of implantation sites, the number of resorption sites, the number of corpora lutea in the ovaries, and the pre- and post-implantation loss rates. It is therefore concluded that administration of Carapa guianensis seed oil did not bring about any toxic effect on pregnancy in Wistar rats.

Abstract
Neutropenic enterocolitis (NE) is an unusual acute complication of neutropenia, most often associated with leukemia and lymphoma which is characterized by segmental cecal and ascending colon ulceration that may progress to necrosis, perforation, and septicemia. We present a case of neutropenic enterocolitis in a patient with non-small-cell lung cancer who received docetaxel and flavopiridol as part of a phase I clinical trial and review cases in the literature where docetaxel was involved. Given the increased use of docetaxel and other taxanes in the treatment of advanced lung cancer, physicians should be aware of this potential toxicity of therapy.

Abstract
Eighteen markers allocated to human syntenic groups 1, 2, 7, 14, 15, 17 and 22 were assigned to the chromosome complement of the neotropical primate Ateles paniscus chamek. These new allocations and existing gene charts in this species were compared with chromosome painting patterns produced by human chromosome probes in the congeneric species A teles geoffroyi and with available data on the human genome and gene mapping. These comparisons showed congruent findings in Ateles and provided good evidence of how several human syntenic groups were evolutionarily rearranged.

Abstract
Heterozygous carriers of HPRT1 mutations responsible for Lesch-Nyhan syndrome can be detected by analysis of somatic cell hybrids derived from peripheral blood lymphocytes and Hprt1-negative cells of rodent origin followed by selection in culture medium containing hypoxanthine, aminopterine, and thymidine (HAT). The parental origin of the X chromosome containing the normal HPRT1 allele in HPRT1(+) hybrid cell lines can be determined by molecular haplotyping attributable to highly polymorphic X-linked markers. We used this procedure to study a presumed carrier whose paternal active X chromosome always segregated in the cell hybrids derived from her. Conversely, her maternal X chromosome was systematically absent in most cell hybrids, or when present, it was inactive and coexisted with an active, paternal X chromosome. These results clearly demonstrated that the proband was a heterozygous carrier of a mutation responsible for HPRT1 deficiency.

Abstract
We propose and demonstrate the direct recording of submicrometer relief gratings in amorphous hydrogenated carbon (a -C:H) films by reactive ion etching (RIE) for use as diffractive optical components. The high refractive index of this film and its transparency in the IR make such structures promising candidates for IR-transmission diffractive optical components. The structures are holographically recorded in photoresist and then transferred to a thin aluminum layer that is used as a mask for RIE of the a -C:H films. The diffraction measurements of the structures recorded in these films demonstrated the feasibility of using the materials as diffractive optical components.

Abstract
A simulation of the profile of holographically recorded structures in photoresists is performed. In addition to its simplicity this simulation can be used to take into account the effects that arise from exposure, photosensitization, development, and resolution of positive photoresists. We analyzed the effects of isotropy of wet development, nonlinearity of the photoresist response curve, background light, and standing waves produced by reflection at the film-substrate interface by using this simulation, and the results agree with the experimentally recorded profiles.

Abstract
The authors evaluated the isoniazid acetylating phenotype and measured hematocrit, hemoglobin, glucose-6-phosphate dehydrogenase and glutathione reductase activities plus serum sulfadoxin levels in 39 patients with paracoccidioidomycosis (33 males and 6 females) aged 17 to 58 years. Twenty one (53.84%) of the patients presented a slow acetylating phenotype and 18(46.16%) a fast acetylating phenotype. Glucose-6-phosphate-dehydrogenase (G6PD) activity was decreased in 5(23.80%) slow acetylators and in 4(22.22%) fast acetylators. Glutathione reductase activity was decreased in 14(66.66%) slow acetylators and in 12(66.66%) fast acetylators. Serum levels of free and total sulfadoxin were higher in slow acetylator (p less than 0.02). Analysis of the results permitted us to conclude that serum sulfadoxin levels are related to the acetylator phenotype. Furthermore, sulfadoxin levels were always above 50 micrograms/ml, a value considered therapeutic. Glutathione reductase deficiency observed in 66% of patients may be related to the intestinal malabsorption of nutrients, among them riboflavin, a FAD precursor vitamin, in patients with paracoceidioidomycosis.

Abstract
The authors evaluated the relationships among renal function, acetylator phenotype and serum sulfadiazine levels in 22 patients with paracoccidioidomycosis treated with 1 tablet of cotrimazine (a combination of 820 mg sulfadiazine and 180 mg trimethoprim) administered orally every 12 hours. Fifteen patients (68.18%) presented free sulfadiazine levels above 50 micrograms/ml, 6(27.28%) presented serum levels above 40 micrograms/ml, and 1(4.54%), levels lower than 40 micrograms/ml, this being the patient in which treatment failed. The highest free sulfadiazine levels were obtained in slow acetylator patients with reduced renal function. One patient with neuroparacoccidioidomycosis presented free sulfadiazine levels in cerebrospinal fluid corresponding to 55% of the serum levels. Finally, the authors consider cotrimazine to be an important therapeutic alternative for neuroparacoccidioidomycosis and conclude that administration every 12 hours can provide therapeutic sulfadiazine levels. They also suggest that when the sulfadiazine-trimethoprim combination is used, the therapeutic levels of sulfadiazine should be above 40 micrograms/ml.
