This study examined changes in the propulsive force and stroke parameters of arm-amputee and able-bodied swimmers during tethered swimming. Eighteen well-trained female swimmers (nine unilateral arm amputees and nine able-bodied) were videotaped performing maximal-effort 30 s front-crawl swims, while attached to a load…

OBJECTIVE: The study's objective was to determine the CD4 count and laboratory abnormalities in adults infected with HIV at initiation of antiretroviral therapy (ART) in Togo. METHODS: A retrospective and descriptive study was made of all patients on HAART in 2009 in Togo. RESULTS: A total of 5106 patients were inclu…

PURPOSE: There's no consensus about what defines a conversion for laparoscopic-assisted colorectal resection (LACR). This study's goal was to assess the utility of a strict incision length (IL) definition of conversion (incision > 7 cm) and compare it with results obtained when the surgeon determined (SD) if a LACR had…

Using an 'at-risk' sample of African American girls, the present study examined the link between girls' retrospective reports of pubertal timing, girls' perceived relative pubertal timing, and their behavioral and emotional problems as rated by the girls themselves (N=102; 11-17 years), as well as teachers and parents.…

The study's objective was to examine the relationship between cesarean section delivery and the initiation of breastfeeding in a representative sample of 1695 Puerto Rican women aged 15 to 49 years, who delivered their last healthy singleton child in Puerto Rico between 1990 and 1996. Secondary analysis of data collect…

BACKGROUND: External cephalic version (ECV) is accepted as a means of reducing the rate of breech presentation at term. Routine use of tocolysis prior to an ECV has been described to increase its success rate. The study's objective was to evaluate the efficacy of oral nifedipine as a tocolytic agent prior to ECV, and t…

In this study, I examined direct and indirect influences of sensation seeking, a personality trait, on adolescent drug use. I hypothesized that some or even most of the contribution of sensation seeking to drug use by adolescents is mediated through association with deviant peers and communication with peers that is fa…

Italians in Britain have low rates of coronary heart disease while South Asians have high rates, which correspond to a tendency to central abdominal fat deposition and overweight. World variations in attitudes to body size are thought to be related to economic security. This cross-sectional study employed a range of me…

A methodology for sampling homeless populations in inner Melbourne was developed to study their health status and prevalence of tuberculosis. This paper describes the design, development and implementation of the project. The results of health status and tuberculosis analysis are published elsewhere. Involvement and in…

Emotional dysregulation is a transdiagnostic process associated with a range of addictive behaviours including problem gambling, with emerging research indicating that emotionally oriented reasons for gambling (i.e., excitement, escape) are associated with problem gambling. However, the relationships between difficulti…

Creativity is increasingly recognized as a core competency for the 21st century, making its development a priority in education, research, and industry. To effectively cultivate creativity, researchers and educators need reliable and accessible assessment tools. Recent software developments have significantly enhanced…

AIMS: DOG1 and protein kinase C (PKC) theta are both sensitive immunohistochemical markers of gastrointestinal stromal tumour (GIST). However, there are conflicting data regarding the specificity of the most commonly used PKC theta antibody (clone 27), and there are no existing data regarding the specificity of the onl…

BACKGROUND: One of the aspects that influences the sitting comfort is the distribution of the pressure applied to the skin by the seat surface. In the scientific literature, many studies show experimental activities in order to evaluate the influence of pressure distribution at the seat-human interface on the comfort e…

The alcohol dehydrogenase (ADHs) and aldehyde dehydrogenases (ALDHs) involved in alcohol metabolism are polymorphic. Different alleles encode subunits of the enzymes that are related to differences in alcohol metabolism with different ethnic groups. This study examined the allele frequencies at the ADH1, ADH2, ADH3 and…

This study addressed the question of how to structure coalitions in order to increase their engagement in multiple strategies for health promotion and consequently to improve their effectiveness. Three structural variables were chosen: (i) coalition's heterogeneity, captured by the professional diversity of its members…

Dogs can use the placement of an arbitrary marker to locate hidden food in an object-choice situation. We tested domestic dogs (Canis familiaris) in three studies aimed at pinning down the relative contributions of the human's hand and the marker itself. We baited one of two cups (outside of the dogs' view) and gave th…

BACKGROUND: Overviews of reviews of healthcare interventions (overviews) integrate information from multiple systematic reviews (SRs) to provide a single synthesis of relevant evidence for decision-making. Overviews may identify multiple SRs that examine the same intervention for the same condition and include some, bu…

BACKGROUND: C-KIT is a receptor tyrosine kinase with oncogenic properties overexpressed in PCa cases. Through the use of an alternative promoter, a truncated c-KIT protein (tr-KIT) of 30-50 kDa is generated, lacking the extracellular and transmembrane domain. Tr-KIT promotes the formation of a multi-molecular complex c…

The study's aim was to investigate the S100A4-mediated mechanisms of the regulation of tumor cell proliferation and migration in the human triple-positive breast carcinoma cell line MCF-7 (TPBC) and triple-negative breast carcinoma cell line MDA-MB-231 (TNBC). The proliferative activity of TNBC more than doubled during…
