food intake of rats increases during pregnancy. this requires changes in the structure of the small intestine to absorb additional food. the aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. duodenum, jejunum and ileum of 18 pregnant sprague-dawley rats (day 7, 14 and 21 of pregnancy) were collected. villous height a...

a simple special protocol using semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with sarcocystis spp. using this method, infected muscles fibers with sarcocystis could easily be differentiated from muscle tissues. this method can be applied for screening of infected muscles with sarcocystis cysts on large number of samples for epi...

Giant cell tumor (GCT) is a primary and benign tumor of bone, albeit locally aggressive in some cases, such as in the epi-metaphyseal region of long bones, predominantly the distal end of femur and proximal end of tibia (1). There are a variety of treatments for a bone affected by GCT, ranging from chemotherapy, radiotherapy, embolization, and cryosurgery, to surgery with the use of chemical or...

Phase-field models of fracture introduce smeared cracks width commensurate with a regularisation length parameter $\epsilon$ and obeying minimum energy principle. Mesh adaptivity naturally suggests itself as means supplying spatial resolution were needed while simultaneously keeping the computational size model small possible. Here, variational-based is proposed for phase-field fracture. The co...

Chosen from István Mayer's very impressive canon of important work on bond orders and related quantities, we explore a paper 2012 which introduced “pseudo spin density matrix” for correlated singlet-state wave functions, leading to “improved” definitions free valence. Examining such the singlet ground states H2, N2 CH+ find that all them exhibit sensible geometry dependences. valence index work...

When assessing election forecasts, two important criteria emerge: their accuracy (precision) and lead time (distance to event). Curiously, in both 2010 2015 the most accurate forecasts came from models having longest time—albeit at 12 months. Can we increase further, supposing tolerate a small decrease accuracy? Here, develop model with of more than 3 years. Our Party Leadership Model relies on...

Abstract This paper is a meta‐analysis of experimental studies dealing with the impact incidental emotions (happiness, sadness, fear, and anger) on financial risk‐taking, so as to explain traditional heterogeneity outcomes in literature. After devising standard search strategy including that comply list eligibility criteria, we code 114 effect sizes at treatment level from 26 selected articles,...

Mammalian cells secrete a large number of small proteins, but their mode of translocation into the endoplasmic reticulum is not fully understood. Cotranslational translocation was expected to be inefficient due to the small time window for signal sequence recognition by the signal recognition particle (SRP). Impairing the SRP pathway and reducing cellular levels of the translocon component Sec6...
