1. Neurosensory analysis of tooth sensitivity during at-home dental bleaching: a randomized clinical trial
Abstract Objective The objective of this study was to evaluate dental sensitivity using visual analogue scale, a Computerized Visual Analogue Scale (CoVAS) and a neurosensory analyzer (TSA II) during at-home bleaching with 10% carbamide peroxide, with and without potassium oxalate. Materials and Methods Power Bleaching 10% containing potassium oxalate was

2. Influence of skin cold sensation threshold in the occurrence of dental sensitivity during dental bleaching: a placebo controlled clinical trial
Abstract Objective This study verified the occurrence of dental sensitivity in patients submitted to a 35% hydrogen peroxide based product (Whiteness HP Maxx 35% – FGM), skin cold sensation threshold (SCST) and its influence on dental sensitivity. Material and Methods Sixty volunteers were divided into 4 groups (n = 15), according to SCST (low: GI and GI

3. Effect of Embryo Thermal Stimulation on the Serum Levels of Immunoglobulins and Corticosterone, and Organ Histopathology of 1 day-old Broilers
ABSTRACT Embryo thermal stimulation has been studied as a means to promote epigenetic changes and to improve broiler health and performance. This study aimed at evaluating immunoglobulin (IgM, IgG, and IgA) titers, serum corticosterone levels, and organ integrity of day-old male Cobb(r) and Ross(r) broilers. Embryos were submitted to hot and cold stimuli (th

4. Angiogenic effects of cryosurgery with liquid nitrogen on the normal skin of rats, through morphometric study
BACKGROUND:Cryosurgery is an efficient therapeutic technique used to treat benign and malignant cutaneous diseases. The primary active mechanism of cryosurgery is related to vascular effects on treated tissue. After a cryosurgical procedure, exuberant granulation tissue is formed at the injection site, probably as a result of angiogenic stimulation of the cr

5. Estudo dos efeitos celulares e vasculares da criocirurgia com nitrogênio líquido, na pele de ratos, por método histopatológico / The study of cellular and vascular effects of cryosurgery with liquid nitrogen, in rat skin, using the histopathological method
Cryosurgery is a very efficient therapeutic technique to treat benign and malignant cutaneous diseases. The primary active mechanism of cryosurgery is related to vascular effects in treated tissue. After a cryosurgical procedure, exuberant granulation tissue is formed at the injection site, probably as a result of angiogenic stimulation of the cryogen and in

6. Cefaleia atribuÃda à ingestÃo ou inalaÃÃo de estÃmulo frio: um modelo experimental
A cefaleia induzida por estÃmulo frio (CIEF) ocorre durante a aplicaÃÃo deste estÃmulo a um indivÃduo externamente, ou por ingestÃo ou inalaÃÃo. A dor à descrita como de curta duraÃÃo e pode ser aguda. A maioria dos estudos mostra maior susceptibilidade de indivÃduos migranosos em desenvolvÃ-la, porÃm esses mecanismos ainda nÃo estÃo bem escl

7. The use of infrared thermographic imaging for pulp vitality evaluation in vivo / Ensaio sobre o uso da termografia infravermelha na avaliação da vitalidade pulpar in vivo
Nowadays, it is known that the determination of the pulp vitality testing only its nerve sensorial response through thermal or electrical tests is discussable because those procedures are not sufficiently sensitive to determine the degree of pulp involvement. Besides the vitality of the pulp does not only depend on its nerve condition, but on its blood suppl

8. Avaliação dos efeitos do laser de Er,Cr:YSGG sobre superfícies radiculares expostas no tratamento da hipersensibilidade dentinária cervical. Estudo in vitro e in vivo / Desensitizing effects of Er:YAG and Er,Cr:YSGG lasers on dentin hypersensitivity. An in vitro and in vivo study
The aim of the present study was to determine the correct parameters of the Er,Cr:YSGG laser in the treatment of cervical dentin hypersensitivity. This work was presented in 3 different stages. In the first one, it was evaluated the decrease in dentin permeability of dentinal tubules after Er,Cr:YSGG laser irradiation in radicular surfaces. Ninety premolars

9. Vascular responses in the hands of patients suffering from migraine
The response of the hand blood vessels to a measured, controlled cold stimulus was determined, using venous occlusion plethysmography, in normal subjects and patients who suffered from migraine. The resting level of hand blood flow was found to be higher in the patients, but the percentage fall in flow that resulted when the cold stimulus was applied was les

10. New intervention in mitral valve prolapse. Use of cold pressor test during echocardiography.
A study was performed in 13 patients with idiopathic mitral valve prolapse and in 21 control subjects to assess the effect of the cold pressor test on systolic motion of the mitral valve. A significant increase in blood pressure occurred in 10 patients with mitral valve prolapse and in 19 controls after immersion of one hand in ice-cold water. M-mode echocar

11. Transcriptome Changes for Arabidopsis in Response to Salt, Osmotic, and Cold Stress1[w]
To identify genes of potential importance to cold, salt, and drought tolerance, global expression profiling was performed on Arabidopsis plants subjected to stress treatments of 4°C, 100 mm NaCl, or 200 mm mannitol, respectively. RNA samples were collected separately from leaves and roots after 3- and 27-h stress treatments. Profiling was conducted with a G

12. C-polymodal nociceptors activated by noxious low temperature in human skin.
1. Fifty-five C-polymodal nociceptors innervating hairy skin in human volunteers were tested for discrete stimulus-response properties through microneurography. 2. All fifty-five units were responsive to mechanical and heat stimuli. Twenty-two (40%) of these exhibited an additional response to noxious low temperature. The twenty-two mechano-heat-cold nocicep
