OBJECTIVE Determining levels of inactivity in the population aged 18 to 60 years old in the city of Manizales. METHODS This was a cross-sectional study with phase correlation of 631 people aged 18 to 60 years in Manizales. People were selected by random sampling using the K systematic method. The variables analyzed were age, gender, weekly practice, BMI, hip circumference and initial heart ra...

This study conducted comprehensive and comparative metabolic and lipidomic profiling of a human epithelial breast cell line (MCF-10A), a slightly metastatic (MCF-7), and a highly metastatic (MDA-MB-231) breast cancer cell line using gas chromatography mass spectrometry (GC-MS) and direct infusion mass spectrometry (DI-MS). Among 39 metabolites identified by GC-MS analysis, xanthine, glucose-6-p...

r is called commuting regular ring (resp. semigroup) if for each x,y $in$ r thereexists a $in$ r such that xy = yxayx. in this paper, we introduce the concept of commuting$pi$-regular rings (resp. semigroups) and study various properties of them.

BACKGROUND Substantial bovine viral diarrhea virus (BVDV)-related production losses in North American alpaca herds have been associated with BVDV type Ib infection. OBJECTIVES To classify and differentiate the long-term clinicopathological characteristics of BVDV type Ib infection of alpaca crias, after natural virus exposure. We hypothesized that persistently infected (PI) alpacas specifical...

PURPOSE To compare the 1-year outcome of trabeculectomy and combined phaco-trabeculectomy that were performed with or without a peripheral iridectomy (PI). METHODS In a large tertiary glaucoma clinic, with a single surgeon performing all surgeries, 47 patients scheduled to undergo either a primary trabeculectomy or phaco-trabeculectomy were prospectively randomized to surgery with or without ...

For the first time, we used multilocus sequence typing (MLST) to understand how Romanian group B streptococcus (GBS) strains fit into the global GBS population structure. Colonising isolates recovered from adult human females were tested for antibiotic resistance, were molecularly serotyped based on the capsular polysaccharide synthesis (cps) gene cluster and further characterised using a set o...

Validation of a 5-covariate prognostic index (PI;) (performance status, stage, residual tumor size, histolÃ3gica!grade, and ascitcs) derived from a group of 268 Dutch patients with advanced ovarian carcinoma was performed in a similar study of 301 Danish patients. Analysis of survival suggested an alternative 4-covariate PI (performance status, residual tumor size, age, weight/body surface) for...

The WRKY transcription factor family has more than 70 members in the Arabidopsis (Arabidopsis thaliana) genome, and some of them are involved in plant responses to biotic and abiotic stresses. This study evaluated the role of WRKY45 in regulating phosphate (Pi) uptake in Arabidopsis. WRKY45 was localized in the nucleus and mainly expressed in roots. During Pi starvation, WRKY45 expression was m...

The present study aimed to investigate the effect of different seminal plasma proteins (SPPs) on boar spermatozoa functional characteristics. We investigated the putative protective effect of SSPs on sperm cells motility and velocity, as well as on the integrity of the plasma membrane (PM) during low-temperature storage at 4 °C. SPPs fractions were obtained and purified by gel permeation chroma...
