Proximal basilar artery hemorrhage after submaximal angioplasty for intracranial atherosclerotic disease presenting as a large vessel occlusion treated with pipeline embolization device

Iatrogenic vessel perforation from endovascular intervention is a devastating complication that commonly is treated with vessel sacrifice. We present a unique case of an iatrogenic proximal basilar artery perforation after submaximal angioplasty in a 67-year-old male presenting with an acute basilar artery occlusion with underlying intracranial atherosclerotic disease. Telescoping flow-diverting stents were then deployed to reconstruct the vessel wall with resulting active hemorrhage resolution. Our case documents a successful deployment of flow-diverting stents with resolution of active hemorrhage after an iatrogenic basilar artery perforation.

Air pollution and children's health-a review of adverse effects associated with prenatal exposure from fine to ultrafine particulate matter

BACKGROUND@#Particulate matter (PM), a major component of ambient air pollution, accounts for a substantial burden of diseases and fatality worldwide. Maternal exposure to PM during pregnancy is particularly harmful to children's health since this is a phase of rapid human growth and development.@*METHOD@#In this review, we synthesize the scientific evidence on adverse health outcomes in children following prenatal exposure to the smallest toxic components, fine (PM@*RESULTS@#Maternal exposure to fine and ultrafine PM directly and indirectly yields numerous adverse birth outcomes and impacts on children's respiratory systems, immune status, brain development, and cardiometabolic health. The biological mechanisms underlying adverse effects include direct placental translocation of ultrafine particles, placental and systemic maternal oxidative stress and inflammation elicited by both fine and ultrafine PM, epigenetic changes, and potential endocrine effects that influence long-term health.@*CONCLUSION@#Policies to reduce maternal exposure and health consequences in children should be a high priority.

Comparison of Mechanical Allodynia and Recovery of Locomotion and Bladder Function by Different Parameters of Low Thoracic Spinal Contusion Injury in Rats

BACKGROUND: The present study was designed to examine the functional recovery following spinal cord injury (SCI) by adjusting the parameters of impact force and dwell-time using the Infinite Horizon (IH) impactor device. METHODS: Sprague-Dawley rats (225-240 g) were divided into eight injury groups based on force of injury (Kdyn) and dwell time (seconds), indicated as Force-Dwell time: 150-4, 150-3, 150-2, 150-1, 150-0, 200-0, 90-2 and sham controls, respectively. RESULTS: After T10 SCI, higher injury force produced greater spinal cord displacement (P < 0.05) and showed a significant correlation (r = 0.813) between the displacement and the force (P < 0.05). In neuropathic pain-like behavior, the percent of paw withdrawals scores in the hindpaw for the 150-4, 150-3, 150-2, 150-1 and the 200-0 injury groups were significantly lowered compared with sham controls (P < 0.05). The recovery of locomotion had a significant within-subjects effect of time (P < 0.05) and the 150-0 group had increased recovery compared to other groups (P < 0.05). In addition, the 200-0 and the 90-2 recovered significantly better than all the 150 kdyn impact groups that included a dwell-time (P < 0.05). In recovery of spontaneous bladder function, the 150-4 injury group took significantly longer recovery time whereas the 150-0 and the 90-2 groups had the shortest recovery times. CONCLUSIONS: The present study demonstrates SCI parameters optimize development of mechanical allodynia and other pathological outcomes.

Phytochemical and anti-bacterial activity of epidermal glands extract of Christella parasitica (L.) H. Lev

<p><b>OBJECTIVE</b>To study the morphology, biochemistry and bioactivity of the epidermal glands of the glandular morphotype of Christella parasitica (C. parasitica) (L.) H. Lev.</p><p><b>METHODS</b>Morphological studies on epidermal glands were carried out by using light microscope and scanning electron microscope. To prepare the extract, the shade-dried fronds of glandular morphotype were soaked in acetone. For antibacterial studies paper disc method was followed by using various pathogenic bacteria.</p><p><b>RESULTS</b>Detailed micromorphological, phytochemical and bioactivity studies on a medicinal fern C. parasitica (L.) H. Lev. showed its intraspecific variation in antibacterial activity. The presence or absence of the epidermal glands was the key factor for antibacterial activity in the morphovariants of this species. The epidermal glands were orange-coloured, stalked and elongated ones of about 84.2 µm × 45 µm, and distributed on the undersurface of costa, costules and veins in croziers, young and mature leaves. Frequency of glands varied from 15/cm on costa in mature leaves to 140/cm on costules in croziers. The acetone extract of the glands showed antibacterial activities and also toxic effect against mosquito larvae and tadpoles of frog. Preliminary phytochemical analysis and HPLC studies of the gland extract showed the presence of various kinds of terpenoids, alkaloids, tannins, saponins and flavonoids in it.</p><p><b>CONCLUSIONS</b>The present study shows that epidermal glands of the glandular morphotype of C. parasitica (L.) H. Lev. have several bioactive compounds and such rare morphovariant should be conserved in nature. The next step is to isolate the pure compounds and to screen the bioactivity of individual compounds of the epidermal glands.</p>

Chromatographic finger print analysis of steroids in Aerva lanata L by HPTLC technique

<p><b>OBJECTIVE</b>To determine the chemical profile and steroids composition of the medicinally important plant Aerva lanata (A. lanata) L.</p><p><b>METHODS</b>Preliminary phytochemical screening was done by the method as Harborne described. HPTLC studies were carried out as Harborne and Wagner et al described. The Ethyl acetate-ethanol-water (8: 2: 1.2) was employed as mobile phase for glycosides.</p><p><b>RESULTS</b>The desired aim was achieved using Chloroform-acetone (8: 2) as the mobile phase. The methanolic extract of stem, leaves, root, flower and seeds of A. lanata showed the presence of 30 different types of steroids with 30 different Rf values from 0.04 to 0.97. Maximum number (11) of steroids has been observed in leaves followed by root (10).</p><p><b>CONCLUSIONS</b>HPTLC profile of steroids has been chosen here to reveal the diversity existing in A. lanata. Such finger printing is useful in differentiating the species from the adulterant and act as biochemical markers for this medicinally important plant in the pharma industry and plant systematic studies.</p>
