Delays in communication networks: Lets consider a bit pipe which offers a capacity of C bits/sec. Assuming we have packets of a fixed length L traversing the bit pipe with the time between packet arrivals being T. If L/C < T then the packets are moving out faster than they come in and we can use the bit pipe to its maximum capacity. However, the preceding statement is true only if L and T are d...

Cytoplasmic male sterility (CMS) systems represent ideal mutants to study the role of mitochondria in pollen development. In sunflower, CMS PET2 also has the potential to become an alternative CMS source for commercial sunflower hybrid breeding. CMS PET2 originates from an interspecific cross of H. petiolaris and H. annuus as CMS PET1, but results in a different CMS mechanism. Southern analyses...

Background: Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have emerged as a promising experimental tool for translational heart research and drug development. However, their usability as a human adult cardiomyocyte model is limited by their functional immaturity. Our aim is to analyse quantitatively those characteristics and how they differ from adult CMs. Methods and R...

The aim of this study was to investigate the potential antidepressive-like effect of tetramethylpyrazine (TMP), one of available blood-activating and stasis-eliminating components from traditional Chinese medicines, in chronic mild stress (CMS)-induced rat model of depression. Male Sprague-Dawley (SD) strain rats were divided into six matched groups (n = 14 in each group) based on their sucrose...

BACKGROUND Australian General Practitioners (GPs) are in the forefront of primary health care and in an excellent position to communicate with their patients and educate them about Complementary Medicines (CMs) use. However previous studies have demonstrated that GPs lack the knowledge required about CMs to effectively communicate with patients about their CMs use and they perceive a need for i...

BACKGROUND Chronic mountain sickness (CMS) is a complex medical and public health problem that seriously affects highland immigrants. This study investigated relationships between community-level factors and CMS. METHODS In this ecological study, data on age- and ethnicity-standardized CMS rates, community factors, and controlling variables were obtained from 2009-2010 surveys of 108 Chinese ...

Laminin-332 is a heterotrimeric basement membrane component comprised of the α3, ß3, and γ2 laminin chains. Laminin-332 modulates epithelial cell processes, such as adhesion, migration, and differentiation and is prominent in many embryonic and adult tissues. In skin, laminin-332 is secreted by keratinocytes and is a key component of hemidesmosomes connecting the keratinocytes to the underlying...

BACKGROUND Accumulating epidemiological evidence shows that life event stressors are major vulnerability factors for psychiatric diseases such as major depression. It is also well known that the resident intruder paradigm (RIP) results in aggressive behavior in male rats. However, it is not known how resident intruder paradigm-induced aggression affects depressive-like behavior in isolated male...

Collagenous micronodules (CMs) are microscopic stromal nodular eosinophilic fibrillar collagen deposition of uncertain histogenesis seen in prostatic adenocarcinoma. Per the 2005 International Society of Urologic Pathology (ISUP) consensus conference, they are categorized as Gleason pattern 3. This study analyzes morphological and clinical features of CMs from a large series of radical prostate...
