An experiment was conducted to evaluate the effects of in ovo injection of chrysin, quercetin and ascorbic acid on hatchability, somatic attributes, hepatic antioxidant status and early post-hatch growth performance of broiler chicks. Four hundred and eighty embryonated broiler breeder eggs containing live 18-day-old embryos were divided into six groups of 80 eggs each. One group remained intact and served as a control group (i), whereas the other five groups were injected with the prepared injection solutions as follows: (ii) 0...

Although endovascular aneurysm repair (EVAR) in the abdominal aorta has reduced the perioperative mortality when compared with open repair, the need for reintervention after complications such as endoleak may be presented in up to 20% of the cases. Type II endoleak from branch vessels is often benign but can potentially be associated with progressive abdominal aortic aneurysm growth and sac expansion. We present a rare case of a patient who presented with sac expansion and psoas hematoma due to Type II endoleak from "unusual" collaterals of IMA and was treated successfully with endoleak microembolization and percutaneous decompression of the hematoma...

A 28-year-old Filipino male was admitted due to high-grade fevers and dyspnea on a background of chronic cough and weight loss. Due to clinical and echocardiographic signs of cardiac tamponade, emergency pericardiocentesis was performed on his first hospital day. Five days after, chest radiographs showed new pockets of radiolucency within the cardiac shadow, indicative of pneumopericardium. On repeat echo, air microbubbles admixed with loculated effusion were visualized in the anterior pericardial space. Constrictive physiology was also supported by a thickened pericardium, septal bounce, exaggerated respiratory variation in AV valve inflow, and IVC plethora...

The spindle assembly checkpoint (SAC) is an evolutionarily conserved mechanism, exclusively sensitive to the states of kinetochores attached to microtubules. During metaphase, the anaphase-promoting complex/cyclosome (APC/C) is inhibited by the SAC but it rapidly switches to its active form following proper attachment of the final spindle. It had been thought that APC/C activity is an all-or-nothing response, but recent findings have demonstrated that it switches steadily. In this study, we develop a detailed mathematical model that considers all 92 human kinetochores and all major proteins involved in SAC activation and silencing...

Pericytes are believed to originate from either mesenchymal or neural crest cells. It has recently been reported that pericytes play important roles in the central nervous system (CNS) by regulating blood-brain barrier homeostasis and blood flow at the capillary level. However, the origin of CNS microvascular pericytes and the mechanism of their recruitment remain unknown. Here, we show a new source of cerebrovascular pericytes during neurogenesis. In the CNS of embryonic day 10.5 mouse embryos, CD31(+)F4/80(+) hematopoietic lineage cells were observed in the avascular region around the dorsal midline of the developing midbrain...

Histidine phosphotransfer proteins (HPs) are key elements of the two-component signaling system, which act as a shuttle to transfer phosphorylation signals from histidine kinases (HKs) to response regulators (RRs). CYTOKININ INDEPENDENT 1 (CKI1), a key regulator of central cell specification in the Arabidopsis female gametophyte, activates the cytokinin signaling pathway through the Arabidopsis histidine phosphotransfer proteins (AHPs). There are five HP genes in Arabidopsis, AHP1-AHP5, but it remains unknown which AHP genes act downstream of CKI1 in Arabidopsis female gametophyte development...

Single atom catalysts (SACs) have attracted broad research interest in recent years due to their importance in various fields, such as environmental protection and energy conversion. Here, we discuss the mechanisms of CO oxidation to CO2 over single Ag atoms supported on hexagonal boron-nitride sheets (Ag1/BN) through systematic van der Waals inclusive density functional theory (DFT-D) calculations. The Ag adatom can be anchored onto a boron defect (VB), as suggested by the large energy barrier of 3.12 eV for Ag diffusion away from the VB site...

INTRODUCTION: Phylogenetics and genomics place colugos as the sister group to primates. Therefore their placentation is of interest in an evolutionary perspective. Previous accounts are fragmentary, not readily accessible and sometimes contradictory. METHODS: We have examined archival material covering the early development of fetal membranes and placenta, the fate of the yolk sac and definitive placentation. RESULTS: Initially the trophoblast extended over a rather broad but shallow area, enclosing maternal blood spaces...

Calcium (Ca(2+)) plays essential roles in generative reproduction of angiosperms, but the sites and mechanisms of Ca(2+) storage and mobilization during pollen-pistil interactions have not been fully defined. Both external and internal Ca(2+) stores are likely important during male gametophyte communication with the sporophytic and gametophytic cells within the pistil. Given that calreticulin (CRT), a Ca(2+)-buffering protein, is able to bind Ca(2+) reversibly, it can serve as a mobile store of easily releasable Ca(2+) (so called an exchangeable Ca(2+)) in eukaryotic cells...

BACKGROUND: The understanding of unruptured intracranial aneurysms (IAs) natural history has always played a critical role in pre-surgical or endovascular planning, in order to avoid possible fatal events. Size, shape, morphology and location are known risk factors for aneurysm's rupture, but morphologic parameters alone, may not be sufficient in order to perform a proper rupture risk stratification. METHODS: We performed a systematic PUBMED search and focused on hemodynamics forces which may influence aneurysmal initiation, growth and rupture...

BACKGROUND: Sunken upper eyelid is a commonly found deformity among Asians, mostly due to the aging process and excessive orbital fat removal during oriental blepharoplasty procedures. This deformity is frequently accompanied by multiple, poorly defined upper eyelid folds and blepharoptosis. To date, autologous fat graft has been the treatment of choice for this group of patients. However, accurate placement of the graft in the orbital fat is quite challenging, and it can result in contour irregularities when injected into the preseptal plane...
