Clinanthus milagroanthus S. Leiva & Meerow, sp. nov. is described from the Department of La Libertad in Peru. The new species is most closely related to C. mirabilis (Ravenna) Meerow, with further affinities to C. viridiflorus (R. & P.) Meerow. It can be distinguished from C. mirabilis by its wider leaves, the much more brightly colored and wide spreading limb, and the much lighter colored perigone tube (yellowish green vs. dark green in C. mirabilis). A conspicuous bulge just proximal to the midpoint of the tube is a unique character of the new species. © Segundo Leiva, Alan W. Meerow.

The effects of replacing cocoa butter with different percentages and proportions of a mango kernel fat/palm olein (MKF/POL) blend, are reported. Samples were prepared by melting together mango kernel fat, palm olein, cocoa butter and cocoa mass and powdered sugar combinated. The samples were milled, conched, tempered, and molded to obtain three sets of seven samples as follows: one control omitting mango kernel fat and palm olein, and six samples with cocoa butter replacement of 15 and 22.5% and MKF/POL ratios of 2.3, 4.0, and 9.0. Casson viscosity, Casson yield stress, fat bloom and sensory acceptability were all measured. In fact, all samples had achieved a low Casson viscosity (ηCA) and Casson yield stress (τOCA), which indicates molding and enrobing as appropriate uses. In addition, some significant differences (p ≤ 0.05) were found among samples. Fat bloom was accelerated in the samples relative to control, but high MKF proportions tended to retard appearance of fat bloom. No differences were observed in organoleptic properties between samples and control.

The knowledge of electrical properties and their relationship with moisture content is of great importance in operations of post-harvest and storage in grains. The dielectric properties of sorghum samples were studied at different moisture contents and temperatures (25 at 41 °C), at frequencies of 1 and 10 kHz. In order to measure changes in the capacitance and dissipation factor of the samples, the method of impedance bridge was used. Both the dielectric constant and the dielectric loss factor of the samples increased with increasing moisture content and temperature; however, they decreased with increasing frequency. Models were proposed to relate the dielectric properties to either the moisture (exponential and polynomial) or temperature (linear). © 2017 Walter de Gruyter GmbH, Berlin/Boston 2017.

In recent years, the bagworm Oiketicus kirbyi (Guilding) has become a pest of increasing importance in Peruvian avocado orchards. A study conducted in six commercial orchards evaluated the ecology of, and feeding damage caused by, bagworms on avocado on the southern coast of Peru. In March 2009, the population of live individuals at different locations consisted of second to sixth larval instars. The sex-ratio in the previous generation of bagworms (the parents of larvae) was female-biased, and the mortality rate was higher for females than males. The percentage of mated females varied between 76.7 and 99.1% and declined when the proportion of males was low. The damage caused by bagworm larvae usually results from defoliation, but in the case of O. kirbyi on avocado, the presence of larvae on the fruits was associated with blemishes that limit the marketability of fruits; thus bagworms cause direct economic losses for avocado growers. Future studies are needed to assess the timing of larval emergence with a view to preventing widespread infestation by dispersing neonate bagworms. © 2010 Taylor & Francis.

To determine trends in the prevalence and identify the main risk factors associated with the development of pancreatic cancer. Study of trends in incidence and case-control population consisted of a total of 134 patients. Patients were grouped into: a) Cases: 67 patients diagnosed with pancreatic cancer treated at the Abdomen's Service of the Specialized Surgery Department of the Regional Institute of Neoplastic Diseases "Dr. Luis Pinillos Ganoza "- IREN North during the period 2008 to 2011; and b) Controls: 67 patients diagnosed with gallstones and / or benign biliary disease treated at Belen Hospital in Trujillo during the period 2008 to 2011. The trend curve of incidence of pancreatic cancer showed a curve almost constant throughout the quadrennium 2008 to 2011, with incidence rates of 5.38%, 5.08%, 5.5% and 5.0% respectively. The overall incidence was 5.37%. The trend function was Y = (1756) ± (0.001) (x), with an R2 = 0.318 (p = 0.436). The main risk factors associated with pancreatic cancer were age bigger and equal to 60 years (p = 0.0001), male sex (p = 0.007), diabetes mellitus (p = 0.002) and family history of malignancy (p = 0.016). The trend in incidence in pancreatic cancer was low and constant in its appearance was significantly influenced by age, gender, and presence of diabetes mellitus and family history of cancer.

Determine the effectiveness of surgical treatment and / or adjuvant to improve the quality of life in patients with colon cancer compared to rectal cancer. Cohort study that evaluated 27 patients diagnosed with colon adenocarcinoma (Group A= 12) and rectum (Group B= 15) resectable treated at the Institute Regional of Neoplastic Diseases of Trujillo since the 1 January 2008 until 31 July 2009. The overall life quality, as assessed by the QLQ-C 30 at 3 months postoperatively was 67.86 +/- 17.90 points vs. 68.50 +/- 11.94 points respectively for the patients of groups A and B (p = 0.934).The social function was better in patients undergoing surgery for Group A than Group B , (37.50 + 13.36 points vs. 60.00 + 13.69 points, p = 0.018). Body image at 3 months assessed by the QLQ-CR-29 had an average score of 28.12 +/- 6.12 points and 50.00 +/- 25.00 points for Group A y B respectively (p = 0.034). The Group A patients had a mean score at 6 months for sexual function of 33.33 +/- 12.91 points, while Group B patients this average score was 65.00 +/- 22.36 points (p = 0.016). Both surgeries for colon and rectal cancer are as effective in improving the overall quality of life of these patients, however the social function, body image, and sexual function is better in colon surgery.

Objective: To compare the efficacy of amoxicillin pre and post to prevent postsurgical removal of third molars infection. Material and method: The clinical trial was conducted in the Department of Dentistry Hospital I El Porvenir-ESSALUD (Trujillo, Peru), between July and November of 2013. The 99 patients were randomized into 3 groups: group 1 received 2. g of amoxicillin one hour before surgery, group 2 received 500. mg of amoxicillin and 500. mg immediately after and every 08. hours for 4 days, and group 3 was not given any antibiotic. The surgical procedure was standardized and performed by the same operator, who was blinded to the procedure. The efficacy in preventing infection was measured by three parameters: pain, oral temperature and discharge. To analyze the proportions comparison test was used with p. <. 0,005. Results: No difference was found between amoxicillin before and after surgery to prevent post extraction of third molars infection (p = 0,60). Furthermore, no difference between those groups and the non-antibiotic administration group was found (p = 0,35 and p = 1,00; respectively). Conclusion: The pre and postoperative administration of amoxicillin are not effective to prevent post extraction of third molars infection. © 2014 SECOM.
