Patients with cystic fibrosis (CF) and advanced pulmonary disease have pulmonary limitation of exercise, often associated with arterial oxygen desaturation. Improving oxygenation during exercise by providing supplemental oxygen may improve exercise performance in these patients. To test this, we performed graded exercise stress tests in 22 CF patients with severe pulmonary disease (mean PaO2, 6...

The purpose of this study was to evaluate a technique known as collaborative assessment considering students' and faculty members' perceptions of the value and utility of this approach. Twenty-eight dental hygiene students took eight individual assessments (quizzes) immediately followed by completion of the same assessment in a five-member peer group as part of a didactic dental hygiene course....

Cement is a binding material, a substance that sets and hardens independently, and can bind other materials together. In ancient civilization the binding materials were of traditional type such as jaggery, lead, jute, rice husk etc, now in modern civilization cement is main binding materials. The use of concrete containing high volume fly-ash has recently gained popularity as a resource efficie...

The pulmonary status of 178 asymptomatic asthmatic children with normal time-volume spirograms was further evaluated using flow-volume loops, body plethysmographic studies, and blood gas tensions in arterialized capillary blood. Residual volume (RV) was abnormal in 26 percent, total lung capacity (TLC) in 33 percent, RV/TLC % in 41 percent, and arterial oxygen pressure in 23 percent of them. Al...

The use of mixed venous oxygen saturation (SvO2) in patients with chronic congestive heart failure (CHF) has been advocated to analyze the action of therapy on cardiac index (CI). To evaluate the relationship between CI and SvO2, ten CHF patients (mean age 65 years) were studied before and one, two, three, four (T4), six, eight and 24 hours after oral administration of an angiotensin converting...

Introduction It is an undisputed fact that the abolition of primary school fees has led to vast enrollment gains in several countries. After fees were abolished in Malawi in 1994 and in Uganda in 1997, enrollment in both countries grew by 68 percent (Avenstrup, Liang & Nellemann, 2004). Lesotho’s graduated abolition of fees, beginning in 2000, led to a Grade 1 enrollment increase of 75 percent,...

BACKGROUND The aim of this study was to determine the relationship between body position, pulmonary function (PF) and bronchial blood flow (Q(aw)) in a group of heart failure (HF) and control subjects. METHODS Thirty-six subjects were studied: 24 stable, ambulatory HF patients (HF: LVEF=27±6%, age=65±9 yr) and 12 age- and sex-matched controls (CTRL: LVEF=60±7%, age=62±8 yr). Measures of Q˙(aw...

Laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant Lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. Factors evaluated were Lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 dS cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). The maximum germination in salinity stres...

BACKGROUND The RIFLE classification scheme for acute kidney injury (AKI) is based on relative changes in serum creatinine (SCr) and on urine output. The SCr criteria, therefore, require a pre-morbid baseline value. When unknown, current recommendations are to estimate a baseline SCr by the MDRD equation. However, the MDRD approach assumes a glomerular filtration rate of approximately 75 mL/min/...

OBJECTIVE To determine the risk of nodal metastases to the central compartment from differentiated papillary thyroid carcinoma (PTC) relative to known prognostic variables. DESIGN A 7-year single-institutional retrospective review. SETTING Tertiary academic center. PATIENTS A total of 115 patients undergoing central neck dissection (CND) for PTC or follicular variant PTC (FVPTC). MAIN O...
