1. Doppler Ultrasound Testing Suggests Hemorrhoids in Females may be a Consequence of Impaired Blood Flow Associated with Pelvic Organ Prolapse
Abstract Background It has been observed that there is a high incidence of hemorrhoids in female patients with pelvic organ prolapse. Also, in these patients, hemorrhoidal disease improves after the surgical correction of the pelvic organ prolapse. Objective Our hypothesis was that a cause-effect relationship between pelvic organ prolapse, and hemorrhoids

2. Functional Changes of the Upper Esophageal Sphincter in Gastroesophageal Reflux
Abstract Introduction The upper esophageal sphincter (UES) is a muscular structure located at the transition from the pharynx to the esophagus, with the cricopharyngeal muscle as the most important component. During gastroesophageal reflux, the pressure in the UES elevates, which is apparently a protective mechanism to prevent esophagopharyngeal reflux and

3. Flow volume measurement of arterial venous and cerebrospinal fluid in patients with multiple sclerosis
Resumo Antecedentes A esclerose múltipla (EM) é comumente descrita como uma doença autoimune, embora seu mecanismo exato permaneça desconhecido. Há estudos que afirmam que anormalidades no fluxo venoso podem estar relacionadas à patogênese da EM ou a muitas das manifestações clínicas associadas. Objetivo O objetivo deste estudo é avaliar os volu

4. Comparison of the Efficacy of Septoplasty with Nonsurgical Management in Improving Nasal Obstruction in Patients with Deviated Nasal Septum – A Randomized Clinical Trial
Abstract Introduction In the current era, the major indication for septoplasty is nasal obstruction due to deviated nasal septum (DNS). Even though septoplasty is a commonly performed surgery, its effectiveness in relieving nasal obstruction in DNS has not been proven. Objective The present study involved the measurement of both objective (nasal patency) a

5. Numerical study of upstream disturbances on the performance of electromagnetic and ultrasonic flowmeters
ABSTRACT Electromagnetic and ultrasonic flowmeters are high precision devices that can measure the water flow in pressurized irrigation networks. In these networks, the inadequate installation distance of flow control valves generates upstream disturbances which will increase measurement errors and reduce the accuracy of the equipment. Therefore, estimating

7. Comparison between peak systolic velocity of the inferior thyroid artery and technetium-99m pertechnetate thyroid uptake in differentiating Graves’ disease from thyroiditis
ABSTRACT Objectives The differentiation between the various etiologies of thyrotoxicosis, including those with hyperthyroidism (especially Graves’ disease [GD], the most common cause of hyperthyroidism) and without hyperthyroidism (like thyroiditis), is an important step in planning specific therapy. Technetium-99m (99mTc) pertechnetate thyroid scanning

8. CHLOROPHYLL FLUORESCENCE OF BASIL PLANTS CULTIVATED IN A HYDROPONIC SYSTEM USING TREATED DOMESTIC WASTEWATER
ABSTRACT Different techniques have been used to evaluate the energetic characteristics and damage to the photosynthetic apparatus of plants exposed to different stresses, including the measurement of chlorophyll fluorescence. The objective of this study is to evaluate the photosynthetic response by assessing the fluorescence parameters of chlorophyll a in ba

9. Nitro-Heterocyclic compounds induce apoptosis-like effects in Leishmania (L). amazonensis promastigotes
Abstract Background: Three drugs - pentavalent antimonials, amphotericin B and pentamidine - are currently used for leishmaniasis treatment. They are administered for long periods, only parenterally, and have high cardiac, renal and hepatic toxicities. Therefore, the investigation of new compounds is required. Nitro-heterocyclic derivatives have been used a

11. Nasal patency and otorhinolaryngologic-orofacial features in children
Resumo Introdução: A obstrução nasal é um sintoma comum na infância relacionado a rinite e hipertrofia das tonsilas faríngeas. Na presença de obstrução nasal, a patência nasal pode estar reduzida e a respiração nasal ser substituída por respiração oral. Alterações orofaciais e otorrinolaringológicas estão relacionadas a esse modo de resp

12. Cardiovascular assessment in Female Spotted Paca ( Cuniculus paca )
RESUMO Com o objetivo de fornecer informações da morfofisiologia cardiovascular da Cuniculus paca, um importante roedor neotropical, oito fêmeas adultas saudáveis dessa espécie foram avaliadas três vezes pela ecocardiografia, sob anestesia geral com isoflurano, a cada 15 dias. Os exames foram realizados por um único avaliador experiente, com os animai
