Objective: To compare the outcomes of total laparoscopic to robotic approach for hysterectomy and all indicated procedures after controlling for surgeon and other confounding factors. Methods: Retrospective chart review of all consecutive cases of total laparoscopic and da Vinci robotic hysterectomies between August 2007 and July 2009 by two gynecologic oncology surgeons. Our primary outcome measure was operative procedure time. Secondary measures included complications, conversion to laparotomy, estimated blood loss and length of hospital stay. A mixed model with a random intercept was applied to control for surgeon and other confounders. Wilcoxon rank-sum, chi-square and Fisher’s exact tests were used for the statistical analysis. Results: The 124 patients included in the study consisted of 77 total laparoscopic hysterectomies and 47 robotic hysterectomies. Both groups had similar baseline characteristics, indications for surgery and additional procedures performed. The difference between the mean operative procedure time for the total laparoscopic hysterectomy group (111.4 minutes) and the robotic hysterectomy group (150.8 minutes) was statistically significant (p=0.0001) despite the fact that the specimens obtained in the total laparoscopic hysterectomy group were significantly larger (125 g vs. 94 g, p=0.002). The robotic hysterectomy group had statistically less estimated blood loss than the total laparoscopic hysterectomy group (131.5 mL vs. 207.7 mL, p=0.0105) however no patients required a blood transfusion in either group. Both groups had a comparable rate of conversion to laparotomy, intraoperative complications, and length of hospital stay. Conclusion: Total laparoscopic hysterectomy can be performed safely and in less operative time compared to robotic hysterectomy when performed by trained surgeons.

Chylous ascites is an uncommon postoperative complication of gynecological surgery. We report a case of chylous ascites following a robotic lymph node dissection for a cervical carcinoma. A 38-year-old woman with IB2 cervical adenocarcinoma with a palpable 3 cm left external iliac lymph node was taken to the operating room for robotic-assisted laparoscopic pelvic and para-aortic lymph node dissection. Patient was discharged on postoperative day 2 after an apparent uncomplicated procedure. The patient was readmitted the hospital on postoperative day 9 with abdominal distention and a CT-scan revealed free fluid in the abdomen and pelvis. A paracentesis demonstrated milky-fluid with an elevated concentration of triglycerides, confirming the diagnosis of chylous ascites. She recovered well with conservative measures. The risk of postoperative chylous ascites following lymph node dissection is still present despite the utilization of new technologies such as the da Vinci robot.

Hot Filament Chemical Vapor Deposition of Crystalline Boron Films

Soto, Gerardo The Korean Ceramic Society 2019 한국세라믹학회지 Vol.56 No.3

This article reports on the conditions required for the growth of crystalline boron films on silicon substrates by hot filament chemical vapor deposition method. The reactive gas was 3% diborane diluted in hydrogen. The films were characterized by optical, electronic, and atomic force microscopies; x-ray diffraction; and energy dispersive, electron energy loss, Raman, x-ray photoelectron, and Auger spectroscopies. The parameters that affect the morphologies of the films have been investigated. It was concluded that faceted crystals are produced at low B₂H₆ flows and working pressures below 200 mT. α-boron is produced between 530 and 600℃. Deposition outside this range produces thin films with a wide variety of morphologies. This result indicates that the films crystallize through a process called "abnormal or discontinuous grain growth." It is assumed that this is due to the anisotropic surfaces of boron allotropes.

Aguilera-Soto, J.I.,Ramirez, R.G.,Arechiga, C.F.,Mendez-Llorente, F.,Lopez-Carlos, M.A.,Silva-Ramos, J.M.,Rincon-Delgado, R.M.,Duran-Roldan, F.M. Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.10

The study was conducted to evaluate and compare the effects of feed additives on ruminal fermentation, nutrient digestibility and performance of lambs fed diets containing 60% wet brewers grains (WBG). In Experiment 1, two simultaneous trials were conducted. Fifty intact ($20.2{\pm}0.8kg\;BW$) lambs were used in a feedlot trial and 10 (rumen cannulated; $32{\pm}1kg\;BW$) in a digestion trial. The pH, volatile fatty acids (VFA) and ammonia-N in lambs were also estimated. Lambs were randomly assigned to one of five diets: i) without additives (Con), ii) with 1% bicarbonate (Bic), iii) with 1% bentonite (Ben), iv) with 33 mg/kg monensin (Mon) and v) with 200 mg/kg fibrolityc enzymes (Enz). In Experiment 2, 120 RambouilletPelibuey intact male lambs ($19.5{\pm}1.5kg\;BW$) were used in a feedlot trial and randomly assigned to four diets: i) without additives (control), ii) with 1% Bic, iii) with 33 mg/kg Mon and iv) with 1% Bic and 33 mg/kg Mon. In Experiment 1, lambs fed diets containing Bic or Mon had significantly higher final weight, DMI, ADG than other lambs. However, apparent DM, OM, CP, NDF and ADF digestibilities and ruminal individual VFA content were similar (p>0.05) among treatments. Conversely, treatmentcollection period interaction was significant for ruminal pH and NH3. In Experiment 2, lambs fed diets containing a Bic and Mon combination had significantly higher final weight, DMI and ADG. It is concluded lambs fed Bic or Mon or Bic and Mon combination had better performance characteristics than lambs on Ben or Enz.

Taxonomic notes on the genus Alsidium C. Agardh, including the merging of Bryothamnion Kützing (Rhodomelaceae)

Garcia-Soto, Gabriela,Lopez-Bautista, Juan The Korean Society of Phycology 2018 ALGAE Vol.33 No.3

In this study, the phylogenetic relationships among the genera Alsidium C. Agardh and Bryothamnion $K{\ddot{u}}tzing$ were investigated. Phylogenetic analyses using the plastid-encoded markers rbcL, psbA, and the mitochondrial barcode region (COI-5P) resolved a well-supported clade that included the species Alsidium corallinum, Bryothamnion seaforthii, and B. triquetrum. Our results indicated that taxonomic recognition of the genus Bryothamnion is not supported and two species of Bryothamnion are reallocated to Alsidium. A reexamination of the morphological definition of Alsidium is provided with an updated diagnosis of the genus and a morphology-based comparison of species that are currently circumscribed under this generic name. Furthermore, we reviewed morphological differences and similarities between Alsidium and the genus Digenea, both belonging to the tribe Alsidieae, discussing the most relevant morphological characters.

Effects of Combining Feed Grade Urea and a Slow-release Urea Product on Characteristics of Digestion, Microbial Protein Synthesis and Digestible Energy in Steers Fed Diets with Different Starch:ADF Ratios

Lopez-Soto, M.A.,Rivera-Mendez, C.R.,Aguilar-Hernandez, J.A.,Barreras, A.,Calderon-Cortes, J.F.,Plascencia, A.,Davila-Ramos, H.,Estrada-Angulo, A.,Valdes-Garcia, Y.S. Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.2

As a result of the cost of grains, the replacement of grains by co-products (i.e. DDGS) in feedlot diets is a common practice. This change produces diets that contain a lower amount of starch and greater amount of fibre. Hypothetically, combining feed grade urea (U) with slow release urea (Optigen) in this type of diet should elicit a better synchrony between starch (high-rate of digestion) and fibre (low-rate of digestion) promoting a better microbial protein synthesis and ruminal digestion with increasing the digestible energy of the diet. Four cannulated Holstein steers ($213{\pm}4$ kg) were used in a $4{\times}4$ Latin square design to examine the combination of Optigen and U in a finishing diet containing different starch:acid detergent fibre ratios (S:F) on the characteristics of digestive function. Three S:F ratios (3.0, 4.5, and 6.0) were tested using a combination of U (0.80%) and Optigen (1.0%). Additionally, a treatment of 4.5 S:F ratio with urea (0.80% in ration) as the sole source of non-protein nitrogen was used to compare the effect of urea combination at same S:F ratio. The S:F ratio of the diet was manipulated by replacing the corn grain by dried distillers grain with solubles and roughage. Urea combination did not affect ruminal pH. The S:F ratio did not affect ruminal pH at 0 and 2 h post-feeding but, at 4 and 6 h, the ruminal pH decreased as the S:F ratio increased (linear, p<0.05). Ruminal digestion of OM, starch and feed N were not affected by urea combination or S:F ratio. The urea combination did not affect ADF ruminal digestion. ADF ruminal digestion decreased linearly (p = 0.02) as the S:F ratio increased. Compared to the urea treatment (p<0.05) and within the urea combination treatment (quadratic, p<0.01), the flow of microbial nitrogen (MN) to the small intestine and ruminal microbial efficiency were greater for the urea combination at a S:F ratio of 4.5. Irrespective of the S:F ratio, the urea combination improved (2.8%, p = 0.02) postruminal N digestion. As S:F ratio increased, OM digestion increased, but ADF total tract digestion decreased. The combination of urea at 4.5 S:F improved (2%, p = 0.04) the digestible energy (DE) more than expected. Combining urea and Optigen resulted in positive effects on the MN flow and DE of the diet, but apparently these advantages are observed only when there is a certain proportion of starch:ADF in the diet.
