Influence of feed form and source of soybean meal on growth performance, nutrient retention, and digestive organ size of broilers. 2. Battery study.

Two experiments were conducted to determine the apparent ileal digestibility (AID) of the amino acids (AA) of 4 commercial soybean meals (SBM) from the United States (USA-1, 48.1% CP and USA-2, 46.2% CP), Brazil (BRA, 47.6% CP), and Argentina (ARG, 46.3% CP) and the effects of the inclusion of these SBM in diets in mash, crumble, or pellet form on growth performance, total tract apparent retention of nutrients, and digestive organ size in broilers reared in cages from 1 to 25 d of age. In experiment 1, the AID of Lys was higher (P < 0.05) for the USA-2 than for the BRA SBM, with the SBM from USA-1 and ARG being intermediate. In experiment 2, 12 diets were arranged as a 3 × 4 factorial with 3 feed forms (mash, crumbles, and pellets) and the 4 sources of SBM used in experiment 1. The feeds were isonutritive and the AID of the AA of the SBM obtained in experiment 1 was used for diet formulation. Broilers fed mash had lower (P < 0.001) ADFI and ADG and poorer (P < 0.001) feed-to-gain ratio than broilers fed crumbles or pellets but source of SBM did not affect growth performance. Nitrogen retention was higher (P < 0.01) in birds fed mash than in birds fed crumbles or pellets at all ages. The total tract apparent retention of nutrients was lower (P < 0.05) for the BRA and ARG SBM diets than for the USA-1 and USA-2 SBM diets. Gizzard empty relative weight (% BW) was higher and gizzard pH lower for broilers fed mash than for broilers fed crumbles or pellets (P < 0.001). The results indicate that crumbling or pelleting of the diets improved growth performance of broilers from 1 to 25 d of age. Diets formulated with analyzed rather than calculated AID of AA of the SBM sources resulted in similar broiler performance.

Improving the binding capacity of Ni2+ decorated porous magnetic silica spheres for histidine-rich protein separation.

Biomagnetic immobilization of histidine-rich proteins based on the single-step affinity adsorption of transition metal ions continues to be a suitable practice as a cost effective and a up scaled alternative to the to multiple-step chromatographic separations. In our previous work, we synthesised Porous Magnetic silica (PMS) spheres by one-step hydrothermal-assisted modified-stöber method. The obtained spheres were decorated with Ni(2+) and Co(2+), and evaluated for the capture of a H6-Tagged green fluorescence protein (GFP-H6) protein. The binding capacity of the obtained spheres was found to be slightly higher in the case Ni(2+) decorated PMS spheres (PMSNi). However, comparing with commercial products, the binding capacity was found to be lower than the expected. In this way, the present work is an attempt to improve the binding capacity of PMSNi to histidine-rich proteins. We find that increasing the amount of Ni(2+) onto the surface of the PMS spheres leads to an increment of the binding capacity to GFP-H6 by a factor of two. On the other hand, we explore how the size of histidine-rich protein can affect the binding capacity comparing the results of the GFP-6H to those of the His-tagged α-galactosidase (α-GLA). Finally, we demonstrate that the optimization of the magnetophoresis parameters during washing and eluting steps can lead to an additional improvement of the binding capacity.

Design and characterization of Ni2+ and Co2+ decorated Porous Magnetic Silica spheres synthesized by hydrothermal-assisted modified-Stöber method for His-tagged proteins separation.

The complete elimination of enzymes from the reaction mixture and the possibility of its recycling for several rounds result in great benefits, allowing the reduction of the enzyme consumption and their usability in continuous processes. In this work, it is evaluated the capture of a H6-tagged green fluorescence protein (GFP-H6) on porous magnetic spheres using the Co(2+) and Ni(2+) affinity adsorption as a possible cost-effective and up-scaled alternative way for the immobilization of His-tagged proteins. For this purpose, Porous Magnetic Silica (PMS) spheres were synthesized by one-step hydrothermal-assisted modified-Stöber method. The obtained spheres have a homogenous size distribution of 400 nm diameter. The γ-Fe(2)O(3) nanoparticles are homogenously distributed in the silica matrix. The obtained PMS spheres have a saturation magnetization of about 10 emu/g. Magnetophoresis measurements show a total separation time of 16 min at 60 T/m. The obtained PMS spheres were successfully and homogenously decorated with Co(2+) and Ni(2+) and then evaluated for the capture of a GFP-H6 protein. The results were compared with the performance of the commercial beads Dynabeads® His-Tag Isolation & Pulldown.

[Cystic ureteritis in a kidney transplantation candidate]. / Ureteritis quística en paciente candidata a trasplante renal.

Cystic ureteritis is a very uncommon pathology, whose pathogenesis is not well established. It is usually asociated with chronic infectious factors. It presents unspecific symptoms but characteristic radiologic findings. There is not an especific treatment for this disease. Kidney transplant is the final pathway for patients with chronic renal failure. We report a case of cystic ureteritis diagnosed during pre-transplant study.

Ureteritis quística en paciente candidata a trasplante renal / Cystic ureteritis in a kidney trasplantation candidate

La ureteritis quística es una patología muy infrecuente, sin que hasta el momento se haya establecido su patogénesis exacta. Se presenta con sintomatología inespecífica, pero sin embargo los hallazgos radiológicos son bastante orientativos. No hay un tratamiento específico para estos pacientes, siendo el trasplante renal el paso final para los que desarrollen insuficiencia renal crónica terminal (IRCT).Presentamos un caso de ureteritis crónica diagnosticado durante el estudio pretrasplante de una paciente con IRCT (AU)

Epidemiology of cerebrospinal Elaphostrongylus cervi infection in red deer in central Spain.

Elaphostrongylus cervi produces a subclinical cerebrospinal disease in many wild and domestic ruminants from Europe, North America and New Zealand and has recently been described in Spain. To determine some aspects of its epidemiology, 121 red deer (Cervus elaphus) from central Spain were sampled during 2000. The prevalence (7%) and mean worm burden (3.8 worms per brain) were similar to the values previously recorded in other European areas. The infection was only detected in young deer during the winter. The estimation of larval production in the faeces was not a reliable method of diagnosing E. cervi infection.

Aneurisma calcificado de la arteria renal en paciente monorrena, una patología inusual / Renal artery calcified aneurysm in a solytary kidney woman patient, rare pathology

Los aneurismas de la arteria renal son infrecuentes. La prevalencia real de los mismos en la población general es desconocida, aunque se estima que es inferior al 0,4%. Con el uso cada vez mayor de la Angiografía y la Tomografía Computerizada (TC), así como por la mejora en las técnicas de imagen, cada vez se diagnostican con más frecuencia. Las causas más comunes son la displasia fibromuscular y la oclusión arteriosclerótica de la arteria renal. Generalmente no hay una clínica patognomónica de los aneurismas renales, produciendo síntomas inespecíficos como dolor en el costado, hematuria, hipertensión e hipotensión (sospecha de rotura). Presentamos el caso de una paciente monorrena con aneurisma calcificado en la arteria renal

Renal artery aneurysm are uncommon. The true prevalence of renal aneurysms in the general population is unknown (less than 0.4%). Because of more widespread use of Angiography and CT as well as improved imaging techniques, they are diagnosed more frecuently. Fibromuscular dysplasia and arteriosclerotic occlusion of the renal artery are believed to be the most frecuent causes. In general, there are no pathognomonic signs and symptoms of renal aneurysm. Nonspecific complaints include flank pain, hematuria, hypertension and hypotension (suspect rupture of aneurysm). We report a case of a woman with a renal artery calcified aneurysm in a solitary kidney

[Adrenal metastases of Ewing's sarcoma. Report of one case]. / Metastasis suprarrenal de sarcoma de Ewing. A propósito de un caso.

Adrenal metastases are more frequent than primary adrenal carcinoma. The most frequent are, in this order: breast and lung cancer, stomach and kidney carcinomas, adrenal gland contralateral tumors and melanoma. Less frequent are tumours of the bladder, colon, esophagus, gall bladder, liver, pancreas, prostate, stomach and uterus. The rest of the tumours rarely spread toward adrenal glands. The metastases to the adrenal glands caused by sarcomas are rare and normally they happen in the contest of a massive metastases affecting several organs at the same time. We present a case of a patient affected by adrenal metastases of Ewing's sarcoma who has been referred to us for surgical treatment because it is a unique metastases (there is no sing of more illnesses in other organs at the time of the exploration).

Metástasis suprarrenal de sarcoma de Ewing. A propósito de un caso / Adrenal metastases of Ewing's sarcoma. A propos of one case

Los tumores metastásicos suprarrenales son más frecuentes que el carcinoma suprarrenal primario. Por orden de frecuencia se detectan metástasis de carcinomas de mama y pulmón, adenocarcinomas renal y gástrico, carcinoma de glándula suprarrenal contralateral y melanoma. Menos frecuentes son las de carcinomas de vejiga, colon, esófago, vesícula biliar, hígado, páncreas, próstata, estómago y útero. El resto de los tumores raramente se diseminan hacia las glándulas suprarrenales. La afectación metastásica de la glándula suprarrenal por tumores de estirpe sarcomatosa es excepcional y suele darse en el contexto de una enfermedad diseminada con metástasis multiorgánicas. Presentamos el caso de un paciente con metástasis suprarrenal de sarcoma de Ewing que nos es remitido para tratamiento quirúrgico con intención curativa, al tratarse de una metástasis única, ya que no se objetivan signos de enfermedad en otros órganos en el momento de hallarse la citada lesión (AU)

We present the case of a patient that was diagnosed of a high degree NHL, following a biopsy of the piriform sinus' lesion, taker by direct laryngoscopy. Simultaneously he was diagnosed as HIV. The interest of this paper is the total remission of the lymphoma seen after specific HIV treatment only.

[Early glottic carcinoma: a clinico-pathological study]. / Cáncer glótico precoz: estudio clínico-patológico.

UNLABELLED: The aim of the present study is to evaluate histopathological features of malignization of laryngeal dysplasia and recurrence of early glottic carcinoma. PATIENTS AND METHODS: A prospective study was perform in a cohort of 134 patients who underwent surgery between 1992/99 at the ENT department of the Complutense University of Madrid. Tumor localization, malignization rate and recurrence rate were studied in 68 cases of laryngeal dysplasia, 11 of in situ-carcinoma and 55 of microinvasive carcinoma. RESULTS: Nine laryngeal dysplasias experienced invasive carcinoma (13%) and six patients with invasive glottic carcinoma had laryngeal recurrence (11%), all of them with anterior commisure involvement. Eight patients underwent total laryngectomy for recurrence (6%) and three patients died of laryngeal cancer. CONCLUSIONS: Anterior commisure involvement was the most important risk factor in early glottic carcinoma.
