Gomez-Polo, Cristina,Gomez-Polo, Miguel,Martinez Vazquez de Parga, Juan Antonio,Celemin Vinuela, Alicia The Korean Academy of Prosthodonitics 2015 The Journal of Advanced Prosthodontics Vol.7 No.6

PURPOSE. To identify the most frequent natural tooth colors using the Easyshade Compact (Vita -Zahnfabrik) spectrophotometer on a sample of the Spanish population according to the 3D Master System. MATERIALS AND METHODS. The middle third of the facial surface of natural maxillary central incisors was measured with an Easyshade Compact spectrophotometer (Vita Zahnfabrik) in 1361 Caucasian Spanish participants aged between 16 and 89 years. Natural tooth color was recorded using the 3D Master System nomenclature. The program used for the present descriptive statistical analysis of the results was SAS 9.1.3. RESULTS. The results show that the most frequent dental color in the total sample studied is 3M1 (7.05%), followed by the intermediate shade 1M1.5 (6.91%) and 2L1.5 (6.02%). CONCLUSION. According to the research methodology used, and taking into account the limitations of this study, it can be proposed that the most frequent color among the Spanish population is 3M1; the most common lightness group is 2; the most frequent hue group according to the 3D Master System is M and the most frequent chroma group is 1.5.

Elderly onset SLE contributes to 10% of all SLE and is considered a rare disease, the signs and symptoms are common to other more frequent diseases in this age so the differential diagnosis is wide and could represent a great clinical challenge. We report two cases, one patient presented with data of serositis, acute renal failure and glomerulonephritis; while the other had evidence of cerebral vasculitis. Case 1: 60 year old male with 6 months of asthenia, malaise and early-morning bilateral limb edema, received treatment with diuretics without improvement, presenting arterial hypertension. He was admitted with IV NYHA class Congestive HF and left pleural effusion. Laboratory reported Hb 14. 3 g/dl, leucocytes 5750 (normal differential count), ESR of 50 mm/h, creatinine 2. 1 mg/dl, urea 60 mg/dl, urinalysis was positive for albumin, hemoglobin and granular casts; GFR 35 ml/min, and 24-hour albuminuria 3. 8 g. ECHO showed a 68% LVEF and 150 ml pericardial effusion. Immunologic profi le showed positive ANA (1:140), positive anti-dsDNA (1:60), and positive anti-SM (1:65). Kidney biopsy showed focal-segmental glomerulonephritis. Case 2: 68 year-old female positive for Diabetes Mellitus and Arterial Hypertension treated with glibenclamide and captopril. She presented at ER with diplopia, bilateral internuclear ophthalmoplegia and bilateral limb paraparesis, initial head CT-scan was normal, so she was admitted to the hospital. A second simple and contrasted head CT-scan was also normal, then the head MRI showed vasculitis and the brain SPECT revealed hypocaptating areas in midbrain, frontal and parietal cortex. Laboratory reported Hb 13. 3 g/dl, leucocytes 2578, glycose 145 mg/dl, normal creatinine, hepatic profi le and urinalysis. Immunologic profi le reported negative ANA, positive anti-dsDNA (1:95) and positive anti-SM (1:120). Both patients received treatment with Cyclophosphamide and Methylprednisolone with great response.

Combination of an Enzymatically Hydrolyzed Yeast and Yeast Culture with a Direct-fed Microbial in the Feeds of Broiler Chickens

Gomez, S.,Angeles, M.L.,Mojica, M.C.,Jalukar, S. Asian Australasian Association of Animal Productio 2012 Animal Bioscience Vol.25 No.5

A balance trial experiment was carried out to evaluate the potential relationship between an enzymatically hydrolyzed yeast (EHY) and yeast culture combined with a live Bacillus subtilis (Bs) on the productive parameters, ileal digestibility, retention of nutrient and energy and villus morphology in broilers. Seventy two 28 d old, Ross B308 male broilers were assigned to a factorial combination of 2 levels of EHY (0 and 1 kg/ton of feed) and 2 levels of Bs (0 and 125 g/ton of feed). The experiment lasted 2 weeks. Several treatment interactions were observed. EHY-fed broilers showed the lowest feed intake and feed conversion ratio whereas Bs-fed broilers showed the highest feed intake and intermediate feed conversion ratio (EHY and BS interaction, p<0.05). Also, EHY-fed broilers had greater ileal digestibility of dry matter (EHY and BS interaction, p<0.01) and energy (EHY and BS interaction, p<0.05) but these responses were counterbalanced by the combination of EHY and Bs. The thickness of the mucosa was similar between the control and EHY-fed broilers, but was lowest when Bs was added alone (EHY and BS interaction, p<0.01). The thickness of the villus was greater in EHY plus Bs-fed broilers, intermediate for the control and lower for Bs or EHY-fed broilers (EHY and BS interaction, p<0.05). The area of the villus was greater in the control and EHY plus Bs-fed broilers (EHY and BS interaction, p<0.05). In addition, EHY-fed broilers showed greater breast yield and nitrogen retention (p<0.01) and ashes digestibility (p<0.05). On the other hand, Bs-fed broilers had greater carcass and breast weight, nitrogen retention, energy excretion and villus height (p<0.05). In summary, EHY and Bs enhanced some growth, carcass and nutrient retention responses, but did not show any synergic relationship in these responses. Opposite to this, the results suggest that the positive effect of EHY on the feed conversion and digestibility of nutrients were counterbalanced by the addition of Bs.

The Dinoflagellate Genera Brachidinium, Asterodinium, Microceratium and Karenia in the Open SE Pacific Ocean

Gomez, Fernando The Korean Society of Phycology 2006 ALGAE Vol.21 No.4

The morphometry and distribution of the unarmoured dinoflagellates Brachidinium capitatum F.J.R. Taylor, Asterodinium gracile Sournia, Microceratium orstomii Sournia and the toxic species Karenia papilionacea Haywood et Steidinger have been investigated in open waters of the SE Pacific Ocean. The genus Microceratium Sournia is recorded for the first time since the initial description. These taxa showed a high morphological similarity and they may correspond to life stages of a highly versatile single species that is able to project body extensions. Karenia papilionacea showed the higher abundance in the surface waters of the more productive areas (the Marquesas Archipelago and the Perú-Chile Current). Brachidinium capitatum and K. papilionacea often co-occurred, predominating B. capitatum in offshore surface waters. Asterodinium gracile was recorded at the bottom of the euphotic zone (down to 210 m depth), with a shallower distribution in more productive areas. Intermediate specimens of Asterodinium-Brachidinium-Karenia, with variable disposition and size of the body extensions were illustrated.

Perspectives on the concepts of futuristic mineral concentration using microscopic robots

Gomez-Flores Allan,Kim Hyunjung 한국자원공학회 2021 Geosystem engineering Vol.24 No.5

There are technologies to fabricate microscopic (milli, micro, and nano) robots at present, and although their large−scale applications in the field of science remain under development, the technology progress is promising. Thus, we review the advances in the technology to fabricate microscopic robots and explore the concepts of their application in mineral concentration. Microscopic robots have not been applied yet in unit operations for mineral concentration. Nevertheless, it is envisioned that the ultimate implementation of microscopic robots for mineral concentration should occur in the form of hand sorting. Additionally, possible limitations (e.g., mass−production or computational power) of the concept are provided. Based on our review, we concluded that the reality of this application will not be accomplished soon. This short perspective could be used as a reference for future proof of concept in experimental work.

Wild-type p53 is involved in several aspects of cell cycle control and suppression of transformation. inducing either apoptosis or G block in cell cycle progression. Using a recombinant adenovirus containting the wild-type p53 cDNA, the biological effects of the newly expressed wild-type p53 protein were examined in six human glioma cell lines. Three cell lines(U-251 MG. U0373 MG. and A-172) expressed endogenous mutant p53. and the other three(U-87 MG EFC-2, and D54 MG) expressed wild-type p53. The restoration of normal p53-encoded protein in the mutant cell lines induecd apoptosis as assessed by morphological studies using nuclear staining. electron microscopy. and flow cytometric assays. In wild-type p53 cell lines. However, the over expression of wild-type p53 did not result in apoptosis but inhibited cellular proliferation rather drastically and modified the neoplastic phenotype. This study shows that over-expression of wild-type p53 protein by an adenoviral vector induces apoptosis in mutant glioma cells as well as growth arrest in wild-type glioma cells.
