Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Using multiscale lidar to determine variation in canopy structure from African forest elephant trails [PDF]

open access: yes
Recently classified as a unique species by the IUCN, African forest elephants (Loxodonta cyclotis) are critically endangered due to severe poaching. With limited knowledge about their ecological role due to the dense tropical forests they inhabit in ...

The Relationship between Gene Network Structure and Expression Variation among Individuals and Species. [PDF]

open access: yesPLoS Genetics, 2015
Variation among individuals is a prerequisite of evolution by natural selection. As such, identifying the origins of variation is a fundamental goal of biology.

Variations in urban population structure [PDF]

open access: yesDemography, 1964
Hasta ahara no se ha prestado atencion suficiente, en materia de investigacion, al estudio sistematico y cuantitativo de la persisiencia y las variaciones en el tiempo de las caracteristicas espaciales de la distribucion y composicion de la poblacion. Utilizando datos de distritos censales para 1940 y 1960 en dos ciudades (Seatle y Rochester), el autor

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Spatially structured genetic variation in a broadcast spawning bivalve: quantitative vs. molecular traits [PDF]

open access: yes, 2003
Understanding the origin, maintenance and significance of phenotypic variation is one of the central issues in evolutionary biology. An ongoing discussion focuses on the relative roles of isolation and selection as being at the heart of genetically based

Variation in structure and selected properties of Finnish birch wood. IV.

open access: yesSilva Fennica, 1981
Length variation of fibres and vessels was studied in the branches, stems and roots of Roth and Ehrh. The cells were significantly shorter in the branches and roots than in the stems.

Structural and genomic variation in preterm birth [PDF]

open access: yesPediatric Research, 2016
Runs of homozygosity (ROH) are consecutive homozygous genotypes, which may result from population inbreeding or consanguineous marriages. ROH enhance the expression of recessive traits.We mapped ROH in a case control study of women delivering at term compared with women delivering at or before 34 wk gestation. Gene sets known to be important in risk of

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Comparative methods for association studies: a case study on metabolite variation in a Brassica rapa core collection [PDF]

open access: yes, 2011
Background Association mapping is a statistical approach combining phenotypic traits and genetic diversity in natural populations with the goal of correlating the variation present at phenotypic and allelic levels.
