BACKGROUND Weight loss is a well recognised feature of patients with emphysematous chronic obstructive pulmonary disease (COPD). It has been suggested that this weight loss could be due to a hypermetabolic state resulting from the increased oxygen cost of breathing (OCB). To clarify the relation between resting energy expenditure (REE), nutritional state, and OCB these indices were measured in ...

OBJECTIVE Propose a new experimental model of bladder instability in rabbits after partial bladder obstruction. MATERIALS AND METHODS Thirty North Folk male rabbits, weighting 1,700 to 2,820 g (mean: 2,162 g) were studied. The animals were distributed in 2 experimental groups, formed by 15 rabbits each: Group 1 - clinical control. In this group there was no surgical intervention; Group 2 - bl...

The identification of genes involved in the process of neoplastic transformation is essential for analyzing the progression of breast cancer when induced by endogenous and exogenous agents, among which are the estrogens and the organophosphorous pesticides, respectively. It is important to consider the impact of such substances when they are present in combination. In vitro experimental models ...

BACKGROUND Cryoablation (cryo) has a high success rate in the short-term treatment of atrial flutter (AFL), but evidence of long-term efficacy is lacking. The present study reports the long-term effect of cryo of the cavotricuspid isthmus (CTI) in patients with common AFL. METHODS AND RESULTS Thirty-five consecutive patients (28 men; mean age, 53 years) underwent cryo of the CTI. In 34 patien...

Streptococcus pneumoniae serogroup 10 includes four cross-reactive capsular polysaccharide (CPS) serotypes (10F, 10A, 10B, and 10C). In the present study, the structures of CPS10B and CPS10C were determined by chemical and high resolution NMR methods to define the features of each serotype. Both CPS10C and CPS10F had β1-6-linked Galf branches formed from the termini of linear repeating units by...

The ejaculatory mechanism involves 2 reflexes: the "glans-vasal," which seems to bring the semen to the posterior urethra (emission phase of ejaculation), and the "urethromuscular" which ejects it to the exterior (ejection phase). This study investigated the mechanism of bulbocavernosus muscle (BCM) contraction, once the seminal fluid reaches the bulbous urethra. The study included 14 healthy m...

The aim of this paper is to explore the efficacy of whole brain radiotherapy (WBRT) versus WBRT concurrent with erlotinib in patients with multiple brain metastases of lung adenocarcinoma. WBRT was administered at 30Gy/10f in both arms. In the combination arm, 150 mg erlotinib was given each day, starting the first day of radiotherapy and continuing for 1 month following the end of radiotherapy...

Sequence characterized amplified region (SCAR) markers are one of the most effective and accurate tools for microbial identification. In this study, we applied SCAR markers for the rapid and accurate detection of Phytophthora katsurae, the casual agent of chestnut ink disease in Korea. In this study, we developed seven SCAR markers specific to P. katsurae using random amplified polymorphic DNA ...

Results Twenty-three patients [10F/13M, age: 63 (54-75)] had BD diagnosis. Neurologic etiologies were ischemic stroke (52%), intracranial bleeding (39%), hypoxic encephalopathy (4.5%) and transverse sinus thrombosis (4.5%). The Glasgow Coma Scales (GCS) were 9 (5-11) at hospital and 7 (5-9) at ICU admission. The clinical sign encouraging the clinicians to think BD were brain stem areflexia (39%...

The association of alcohol consumption and breast cancer is more pronounced in cases that are positive for estrogen receptor (ER+) than in cases that are negative (ER-). Its mechanism remains to be determined. Deregulation of RNA polymerase III (Pol III) transcription enhances cellular tRNAs and 5S rRNA production, increasing translational capacity to promote cell transformation and tumor forma...
