In this stud., the growth of Oreochromis niloticus both mixed.sex and.males sexually reversed.were analyzed.in concrete pond. in the FES Zaragoza, UNAM, und.r the environmental cond.tions of the Mexico City. The experiment was carried.from May to November 2013, in two concrete pond. of 50 m2. Similar feed.ng regime and.stocking d.nsity of fish were maintained.for the culture systems. d.fferent growth parameters like bod. weight, length, d.ily weight gain (d.G), specific growth rate (SGR), feed.conversion rate (FCR), Fulton’s cond.tion ind.x (K) and.survival were analyzed.d.ring six months culture period. It was found.that culture with monosex males tilapias yield.d.the highest weight, length, d.G and.SGR compared.to mixed.sex populations tilapias. Water quality was monitored.along the experiment. Based.on the results, there were statistically significant d.fferences in size (W = 20942.5, p 5 mg/L), warm water (>20°C), prod.ctive (3) and.slightly basic (pH > 8). Acceptable growth of fish and.a yield.of 3 ton/ha/6 months were obtained.in both two pond.;therefore, the culture of tilapia und.r cond.tions of Mexico City was recommend.d.

Objective: Celiac d.sease (Cd. is an immune-med.ated.systemic d.sord.r triggered.by gluten. It has a variable combination of clinical manifestations and.changes that have been occurring in recent d.cad.s however they are not known in d.tail. The purpose of the article is to compare Classical and.Non-Classical Cd.cases in terms of d.mographic characteristics, d.od.nal biopsy, extraintestinal manifestations, and.associated.comorbid.ties. Materials and.Method.: A comparative retrospective cohort stud. from January 2008 to d.cember 2018. Results: A total of 128 cases were includ.d. 84 Classical (66%) and.44 Non-Classical Cd.(34%). The family history of Cd.was id.ntified.in 14% of cases without d.fferences between groups. The age at d.agnosis was d.stinct for Classical and.Non-Classical Cd.(4.9 ± 4 and.8.3 ± 4 years old.p 0.001), respectively. Important changes were found.within the classical presentation, includ.ng mono symptoms and.a significantly higher rate of intestinal atrophy;p = 0.04. The main Non-Classical Cd.symptom was recurrent abd.minal pain. The extraintestinal manifestations (EIM) were id.ntified.in 42% and.occurred.in both groups. The comparison between groups showed.d.fferences in rates of migraine and.vitamin d.d.ficiency and.was higher for Non-Classical Cd.(p 0.05). Associated.d.seases occurred.in 10.9%, and.type 1 d.abetes was significant for the Non-Classical Cd.group (p = 0.04). Conclusion: The classical Cd.was the most prevalent profile and.presented.a d.crease in the severity of symptoms however remain a higher rate of intestinal atrophy. Recurrent abd.minal pain was the main symptom of Non-Classical Cd. Extraintestinal manifestations and.associated.d.seases presented.an increasing trend.of occurrence among cases of Non-Classical Cd.

An insight into the interaction of collagen type I with apatite in bone tissue was performed.by using d.fferential scanning calorimetry, Fourier transform infrared.spectroscopy, and.molecular mod.ling. Scanning electron microscopy shows that bone organic content incinerate grad.ally through the d.fferent temperatures stud.ed. We suggest that the amid. regions of the type I collagen molecule (mainly C=O groups of the peptid. bond.) will be important in the control of the interactions with the apatite from bone. The amid. I infrared.band. of the collagen type I change when interacting to apatite, what might confirm our assumption. Bone tissue results in a loss of thermal stability compared.to the collagen stud.ed.apart, as a consequence of the d.grad.tion and.further combustion of the collagen in contact with the apatite microcrystals in bone. The thermal behavior of bone is very d.stinctive. Its main typical combustion temperature is at 360°C with a should.r at 550°C compared.to the thermal behavior of collagen, with the mean combustion peak at ca. 500°C. Our stud.es with molecular mechanics (MM+ force field. showed.d.fferent interaction energies of the collagen-like molecule and.d.fferent mod.ls of the apatite crystal planes. We used.mod.ls of the apatite (100) and.(001) planes;ad.itional two planes (001) were explored.with phosphate-rich and.calcium-rich faces;an energetic preference was found.in the latter case. We preliminary conclud. that the peptid. bond.of collagen type I is mod.fied.when the molecule interacts with the apatite, prod.cing a d.crease in the main peak from ca. 500°C in collagen, up to 350°C in bone. The combustion might be related.to collagen type I, as the ΔH energies present only small variations between mineralized.and.non-mineralized.samples. The d.ta obtained.here give a molecular perspective into the structural properties of bone and.the change in collagen properties caused.by the interaction with the apatite.

Nucleic acid.-based.therapies have recently d.veloped.as next-generation agents for treating and.preventing viral infection, cancer, and.genetic d.sord.rs, but their use is still limited.d.e to its relatively poor d.livery into targeted.cells. We d.signed.and.synthesized.new amphiphilic amino acid.d.rivatives (cysteine-based. of low molecular weight, formed.by the same pentapeptid. (AG2: WWCOO) N-acylated. with d.fferent hyd.ophobic chains containing from 12 to 18 carbons, named.AG2-Cn (N), which d.merize by oxid.tion in the presence of pLenti-CMV-GFP Puro plasmid.(P) in the respective gemini. We d.termined.transfection efficiency, critical micelle concentration, particle size, ζ-potential and.cytotoxicity for the d.rivatives obtained. We found.that all the synthesized.compound. were active for d.A d.livery and.had.greater ability to transfect CHO-K1 cells. In particular, AG2-C18 is a promising carrier for gene d.livery because it showed.no cytotoxicity and.its activity was greater than or equal to the commercial actives currently used.

The frequency d.stribution and.severity of the card.ac d.sease und.rlying acute card.ogenic pulmonary ed.ma(APE) to d.fine appropriate subsequent d.agnostic and.management strategies were investigated.in 216 consecutive patients. To this effect, the clinical, electrocard.ographic, echocard.ographic and.angiographic characteristics were analyzed. Coronary artery d.sease was id.ntified.in 185 patients(86%)-146 with acute myocard.al infarction-as the und.rlying cause, isolated.valvular d.sease in 10(5%) and.other causes in 21(11%). Most patients were eld.rly(≥70 years, 72%), hypertensive(71%)and.d.abetic(44%). Among coronary d.sease(CAd. patients, however, 105(57%) showed.cond.ction d.sturbances in theECG(QRS >0.10 s) and.84(45%) had.no anginal pain d.ring pulmonary ed.ma. A 2d.echocard.ogram showed.a 30%incid.nce of mod.rate-severe mitral regurgitation in coronary d.sease and.non-coronary d.sease patients, and.a 67%incid.nce of red.ced.ejection fraction(d.sease patients(73%). A coronary angiography performed.in 99 patients with coronary d.sease showed.multivessel d.sease in 89(91%) with a 32%incid.nce of significant left main d.sease. Therefore, these find.ngs d.monstrate that coronary d.sease is the most common cause of acute pulmonary ed.ma and.it is associated.with a d.stinctly high prevalence of multivessel and.left main d.sease. This d.agnosis, however, may often be overlooked.if no serial enzymatic sampling is performed.given the increased.frequency of cond.ction abnormalities and.lack of anginal pain.
