A long-standing mystery in genome evolution is why short tandem repeats vary so much in length and frequency. Here, we test the hypothesis that body temperature acts to influence the rate and nature of slippage-based mutations. Using the data from both 28 species where genome sequencing is advanced and 76 species from which marker loci have been published, we show that in mammals, maximum repea...

BACKGROUND Newborn telomere length sets telomere length for later life. At birth, telomere length is highly variable among newborns and the environmental factors during in utero life for this observation remain largely unidentified. Obesity during pregnancy might reflect an adverse nutritional status affecting pregnancy and offspring outcomes, but the association of maternal pre-pregnancy body ...

Particles with short-range interactions and a large scattering length have universal low-energy properties that do not depend on the details of their structure or their interactions at short distances. In the 2-body sector, the universal properties are familiar and depend only on the scattering length a. In the 3-body sector for identical bosons, the universal properties include the existence o...

Huntington disease is an adult-onset neurodegenerative disorder that is caused by the expansion of a polyglutamine tract within the Huntingtin (htt) protein. Wild-type htt has been shown to be involved in transcription, transport and cell survival. Here, we demonstrate that increased expression of full-length wild-type htt in mice is associated with a dose-dependent increase in body weight whic...

Two copepod groups – Acartia bifilosa adults and nauplii – were examined for the effect of preservation with 4% formalin solution on their total body length. The length of the same individual was measured before, immediately, one week, and two months after formalin fixation. There was no statistically significant difference in live and preserved copepod body length at any time of measurement ei...

The population of M. incognita, the root knot nematode (RKN) was found infesting five different host plants (okra, banana, sunflower, bottle gourd, and brinjal) out of 24 examined from four districts of Punjab, India (Gurdaspur, Ludhiana, Patiala, and Hoshiarpur). Morphological and morphometrical characterization indicated that in the case of mature female, the characters of body length and wid...

WHY DO SPECIES DIFFER IN LIFESPAN AND WHAT ARE THE DETERMINANTS OF THEIR LONGEVITY? Understanding the main factors that determine variation in species longevity may provide a clue into the leading mechanisms of aging and—what is even more important—outline the key targets for longevity-promoting interventions. Comparative studies on longevity in mammals revealed numerous variables that correlat...

Data on dry biomass and body length are given for 47 species of dung beetles from the southern part Russian Far East. The length-to-body weight relation in specimens dung-beetles was calculated, to enable be estimated information about length. Shown, selection optimal models length-weight relationship depends types trophodynamic relationships its size classes. When conducting ecological studies...

The purpose of the current study was to evaluate the contribution of genetic factors on body configuration related phenotypes. The sample consisted of 119 Belgian nuclear families including 231 males and 229 females. Factor analysis with varimax rotation was carried out to analyse 13 length and circumference measures and the resulting two synthetic traits (LF and CF; linear and circumference fa...

BACKGROUND: Animal breeds are often recognized through their specific characteristics, nevertheless, the breeds' anatomical and biochemical characteristics have not considered yet in many of the researches done on one-humped camels. There are some particular differences in camel breeds due to different climate conditions and rearing necessity. OBJECTIVES: The aim of the current study was to com...
