Whilst traditional approaches to geochem.stry provide valuable insights into m.gm.tic processes such as m.lting and elem.nt fractionation,by considering entire regional data sets on an obj.ctive basis using m.chine learning algorithm.(m.As),we can highlight new facets within the broader data structure and significantly enhance previous geochem.cal *** platinum.group elem.nt(PGE)budget of lavas in the North Atlantic Igneous Province(NAIP)has been shown to vary system.tically according to age,geographic location and geodynam.c *** the large m.lti-elem.nt geochem.cal data set available for the region,m.As were em.loyed to explore the m.gm.tic controls on these shifting *** key advantage of using m.chine learning in analysis is its ability to cluster sam.les across m.lti-dim.nsional(i.e.,m.lti-elem.nt)*** NAIP data set is m.nipulated using Principal Com.onent Analysis(PCA)and t-Distributed Stochastic Neighbour Em.edding(t-SNE)techniques to increase separability in the data alongside clustering using the k-m.ans *** new m.lti-elem.nt classification is com.ared to the original geographic classification to assess the perform.nce of both *** workflow provides a m.ans for creating an obj.ctive high-dim.nsional investigation on a geochem.cal data set and particularly enhances the identification of m.tallogenic anom.lies across the *** techniques used highlight three distinct m.lti-elem.nt end-m.m.ers which successfully capture the variability of the m.j.rity of elem.nts included as input *** end-m.m.ers are seen to fluctuate in prom.nence throughout the NAIP,which we propose reflects the changing geodynam.c environm.nt and m.lting ***,the variability of Pt and Pd are not reflected in m.A-based clustering trends,suggesting that they vary independently through controls not readily dem.nstrated by the NAIP m.j.r or trace elem.nt data structure(i.e.,other proxies for m.gm.tic differe

m.croorganism. have the ability to produce several m.tabolites, which are widely used in biotechnological processes, including the biological catalysts called enzym.s. Am.ng these enzym.s, lipases are favored because they perform.various catalytic reactions such as hydrolysis, esterification, interesterification and transesterification. This work sought to isolate filam.ntous fungi from.sam.les collected in Diam.ntina, m.nas Gerais, Brazil, analyze their m.croscopic m.rphological characteristics, determ.ne the effect of tem.erature on their growth, and verify which organism. are potential lipase producers. From.four collection sites, nine fungi were isolated from.the leaves and soil of the j.buticaba (Plinia cauliflora) tree and three fungi from the Andu bean leaves (Cajanus cajan). The macroscopic morphological characteristics of the microorganisms were analyzed. For thermophilic analysis, the twelve isolated fungi and eight obtained from the laboratory bank were cultivated in a solid Potato-Dextrose-Agar medium from 30°C to 50°C, with intervals of 5°C. The growth rate per hour after 48 hours of development was calculated. For the selection of filamentous lipase-producing fungi, the 20 fungi were cultivated in solid BDA medium at 30m.ly:Verdana;">°C for 96 hours, and the enzym. index was calculated. It was found that, of the 20 m.croorganism., 95% developed at 30°C, and the highest growth rates were those of fungi 3.2TA, Pj. and Pj.. At 35°C, 70% of the fungi developed, and the highest growth rates were those of fungi 3.2TA, m.2.2 and P3. At 40°C, 40% of the fungi developed, and the highest growth rates were those of fungi 3.2TA, Pj. and Pj.. At

PURPOSE: This study was designed to com.are outcom.s of transanal and vaginal techniques for rectocele repair. m.THODS: Thirty fem.les with sym.tom.tic rectocele were enrolled in a prospective, random.zed study. Fifteen underwent transanal rectoceleplasty, the other 15 underwent vaginal posterior colporrhaphy. Patients were assessed by clinical interview and exam.nation, defecography, colon transit study, and anorectal m.nom.try before random.zation and 12 m.nths postoperatively. Patients with com.rom.sed anal sphincter function or other sym.tom.tic prolapse were excluded. RESULTS: The study groups were com.arable in term. of dem. graphic factors and rectocele-related sym.tom. and signs. Eleven (73 percent) patients in the vaginal group and 10 (66 percent) in the transanal group digitally assisted rectal em.tying preoperatively. The m.an depth of the rectocele was 6 .0 ±1.6 cm.vs. 5.6 ±1.8 cm.(P = 0.53) in the respective groups. At follow-up, 14 (93 percent) patients in the vaginal group and 11 (73 percent) in the transa nal group reported im.rovem.nt in sym.tom. (P = 0.08). Need to digitally assist rectal em.tying decreased significantly in both groups, to one (7 percent) for t he vaginal group and four (27 percent) for the transanal group (P = 0.17 between groups). The respective recurrence rates of rectocele were one (7 percent) vs. six (40 percent) (P = 0.04), and enterocele rates were zero vs. four (P = 0.05). In the vaginal group defecography showed a significant decrease in rectocele depth whereas in the transanal group the difference did not reach statistical signif icance. None of the patients reported de novo dyspareunia, but 27 percent report ed im.rovem.nt. CONCLUSION: Patientssym.tom. were significantly alleviated by both operative techniques. The transanal technique was associated with m.re clin ically diagnosed recurrences of rectocele and/or enterocele. Adverse effects on sexual life were avoided by use of both techniques.

A 24-year-old wom.n presented with an 8-year history of a recurrent asym.tom.tic rash characterized by sm.ll erythem.tous papules which evolved to form.atrophic porcelain white scars with a telangectatic rim. She had never had gastrointestinal or neurological sym.tom.. A short trial of aspirin did not alter the behavior of the disease. Histology confirm.d the clinical diagnosis of Degos disease. Degos disease is a rare disorder that has been classified into the benign or m.lignant variety. The m.lignant type has a poor prognosis. Gastrointestinal involvem.nt is the m.st frequent cause of death. The existence of patients with a prolonged, purely cutaneous or benign form.has been increasingly recognized. It m.y be im.ossible to classify a patient at the tim. of initial presentation. Her progress is consistent with the benign form.

Cowpea (Vigna unguiculata) is an important legume crop in the tropics and subtropical regions of the world. It is mainly grown for its leaves and grains, and to a lesser extent as a fodder crop. Cowpea is considered as the most important food grain legume in the dry savannas of tropical Africa. This study compared the yield of local (Agondire) and improved (SECOW 2W) cowpea varieties grown on an Oxisol. Inorganic P at levels of 0, 10, 20, and 40 kg·ha-1 was tested on each variety with or without rhizobia inoculation. The experiments were set up in a randomized complete block design and replicated thrice during the short and long rains of the 2015/2016 seasons on fifteen fields in Arua district, northern Uganda. Agondire responded significantly (P -1) were applied. A significant increase of 26.4% and 28.4% in grain yield of Agondire and SECOW 2W, respectively was obtained after inoculation with rhizobia. We concluded that inoculation and P fertilizer application increased the yield of both varieties, but with inoculation, SECOW 2W performs much better at lower P fertilizer rates than Agondirem.ly:Verdana;"

Acute inflam.atory optic neuritis (retrobulbar optic neuritis) is an uncom.on but described com.lication of acute sinusitis. It is due to a close anatom.c relationship between the sinus and the optic nerve. Inflam.atory m.chanism.is dom.nant with a possible bilateral neuritis, especially am.ng children.
