Estudio Cinético y de Superficie de Respuesta para la Rehidratación de Zanahorias (Daucus carota) Liofilizadas

In this work the effect of temperature on  the kinetics, the diffusion coefficient sand the addition of citric acid and sodium chloride on the rehydration of frozen-dried carrots (Daucus carota) have been studied. The model response surface was 4 factors with 3 central points. For 70 and 93 ºC, no significant differences (a=0.05) for the kinetic constant with mean of 0.42min-1...

Hypertrophy of NADH-diaphorase positive myenteric neurons in rat jejunum after acute infection caused by Toxoplasma gondii

Toxoplasmosis, a globally distributed feline-associated zoonosis caused by the protozoan Toxoplasma gondii, affects birds and mammals, including humans. This study assesses the consequences of acute T. gondii infection for NADH-diaphorase positive myenteric neurons in rat jejunum. Ten male Wistar rats (Rattus norvegicus) were divided into two groups: G1 (n = 5) and G2 (n = 5...

A critical investigation of Romans 4:3: Its determinative value for justice and righteousness

The theological significance of Romans 4 is undisputed and within it the explicit citation in Romans 4:3 is pivotal. It has informed theological thought, stimulated debates, and shaped faith communities for millennia. But does the concept of 'justification by faith' or 'righteousness through faith', as portrayed in Romans 4:3, hold enough essential universal elements for it to...

Determination of disulfide bridges of two spider toxins: hainantoxin-III and hainantoxin-IV

Peptide toxins are usually highly bridged proteins with multipairs of intrachain disulfide bonds. Analysis of disulfide connectivity is an important facet of protein structure determination. In this paper, we successfully assigned the disulfide linkage of two novel peptide toxins, called HNTX-III and HNTX-IV, isolated from the venom of Ornithoctonus hainana spider. Both peptides...

Unusual visual loss after snakebite

Snakebites are endemic in some parts of Thailand, being associated with several complications. Ocular disturbances are uncommon, except in cases of corneal or conjunctival injury, when the eye is directly exposed to the snake venom. The present study presents a case of combined ophthalmic artery occlusion and transient central retinal artery occlusion with macular ischemia after...

Junge Asthmatiker gegen Grippe impfen!

In jungen Jahren beruhen Asthma-Exazerbationen oft auf viralen Infektionen. Eine Studie zeigt, wie gut die Influenzaimpfung helfen könnte.

rACLF, a recombinant snake venom metalloprotease, activates endothelial cells in vitro

Snake venom metalloproteases (SVMPs) comprise a family of snake venom toxins responsible for most of local and systemic effects observed during envenomation by snakes from the Viperidae family. The vascular system and more specifically the endothelium seem to be the preferential targets of these proteins. This work describes the effects of rACLF, a recombinant SVMP from...

Mitochondrial DNA common deletion is not associated with thyroid, breast and colorectal tumors in Turkish patients

Recently, efforts have been focused on mitochondrial DNA changes and their relation to human cancers. Among them, a 4977 bp deletion of mitochondrial DNA, named "common deletion", has been investigated in several types of tumors, with inconsistent results. In this study, we investigated the presence of the common deletion in tissues from 25 breast, 25 colorectal and 50 thyroid...

Renal- and calcium-dependent vascular effects of Polybia paulista wasp venom

In the present study, the effects of Polybia paulista venom (PPV) on renal and vascular tissues were investigated. Isolated kidneys perfused with PPV (1 and 3 μg/mL) had increased perfusion pressure, renal vascular resistance, urinary flow, and glomerular filtration rate; and reduced sodium tubular transport. Histological evaluation demonstrated deposits of proteins in Bowman's...

Necrotic skin lesion in a dog attributed to Loxosceles (brown spider) bite: a case report

Envenomations caused by Loxosceles (brown spider) have been reported throughout the world. Clinical signs associated to bites of these spiders involve dermonecrotic lesions and intense local inflammatory response, besides systemic manifestations such as intravascular hemolysis, thrombocytopenia, disseminated intravascular coagulation and acute renal failure. The present study...

Representações sociais da homeopatia: uma revisão de estudos produzidos no Estado do Espírito Santo

This study attempts to survey the investigations about the representations of homeopathy on the State of Espírito Santo scene. The point of departure was an analysis of six studies of the kind, in which the subjects were professionals acting in the area of health and community members. One of the six studies surveyed society as a whole and a second one focused on users of...

A Bayesian approach to estimate the accuracy of "in-house

Rabies is a vaccine-preventable disease that causes acute encephalitis in mammals, and it is still a significant public health problem in numerous countries. Infected dogs represent the main vectors involved in human rabies. Additionally, cattle rearing close to geographic areas where vampire bats are found presents an important connection with rural epidemiology. We applied two...

Cloning of a novel acidic phospholipase A2 from the venom gland of Crotalus durissus cascavella (Brazilian northeastern rattlesnake)

The phospholipase A2 superfamily encompasses 15 groups that are classified into: secreted PLA2 (sPLA2); cytosolic PLA2 (cPLA2); Ca2+-independent intracellular PLA2 (iPLA2); platelet-activating factor acetylhydrolase (PAF-AH); and lysosomal PLA2. Currently, approximately 700 PLA2 sequences are known, of which 200 are obtained from the venom gland of Crotalinae snakes. However...

Treatment of geophysical data as a non-stationary process

The Kalman-Bucy method is here analized and applied to the solution of a specific filtering problem to increase the signal message/noise ratio. The method is a time domain treatment of a geophysical process classified as stochastic non-stationary. The derivation of the estimator is based on the relationship between the Kalman-Bucy and Wiener approaches for linear systems. In the...

Dental needs in brazilian patients subjected to head and neck radiotherapy

In spite of its recognized benefits in the treatment of malignant tumors, radiation therapy have several side effects in the head and neck region. The evaluation of oral conditions by a dentist is important to prevent or minimize these problems. The aim of this retrospective review was to analyze the dental needs in 357 patients who received radiotherapy in the head and neck...

Distribuição geográfica atual dos algodoeiros perenes no Brasil: primeiro levantamento parcial

Four expeditions, covering regions of Brazil, located between 5.° and 25.° south, latitude, were performed by the authors, during the period from 1962 to 1965. They were supported by the Fundação de Amparo à Pesquisa do Estado de São Paulo and their aims were: (a) to determine the present geographical distribution of perennial forms of cotton plants; (b) to get samples of these...
