Innovative approach for prevention and treatment of post subarachnoid hemorrhage vasospasm: A preliminary report.

More than one third of patients with subarachnoid hemorrhage (SAH) develop clinically significant vasospasm, as a leading morbidity and mortality factor for these patients. It is widely accepted that a) Degradation products of blood are the causative factors of vasospasm b) The amount of subarachnoid blood seen on admission CT is correlated to the risk of vasospasm c) Reducing the subarachnoid clot burden at the time of surgery reduces the risk of vasospasm. But there is no existing method to clear the blood from subarachnoid spaces satisfactorily.

"True" mycotic aneurysm of the anastomotic site of the renal allograft artery.

The incidence of vascular complications after renal transplant as reported varies from 3.5% to 14%. Pseudoaneurysm formation at the site of the anastomosis is a rare complication, and only a few cases have been reported.

Quality improvement and cost savings after implementation of the Leapfrog intensive care unit physician staffing standard at a community teaching hospital.

Background: Prior studies have shown that implementation of the Leapfrog intensive care unit physician staffing standard of dedicated intensivists providing 24-hr intensive care unit coverage reduces length of stay and in-hospital mortality. A theoretical model of the cost-effectiveness of intensive care unit physician staffing patterns has also been published, but no study has examined the actual cost vs. cost savings of such a program.

Agonist treatment in opioid use: advances and controversy.

Opioid dependence is a chronic relapsing condition which requires comprehensive care; pharmacological agents form the mainstay of its long term treatment. The two most popular approaches are the harm reduction method using agonists and the complete abstinence method using antagonists. Currently, particularly from the harm minimization perspective and the low feasibility of an abstinence based approach, there is an increasing trend toward agonist treatment.

IgG subclass responses to proinflammatory fraction of Brugia malayi in human filariasis.

Background & Objectives: Earlier we demonstrated that immunization with F6, a proinflammatory molecular fraction isolated from the human filarial parasite Brugia malayi, protected the host and eliminated the infection in Mastomys coucha by a Th1/Th2 response including IgG2a antibody response. Whether F6 molecules become accessible to human host during natural course of infection and elicit similar response is not known. The present study was undertaken to determine the profile of IgG subclasses specifically reactive to F6 in different categories of bancroftian filariasis cases to infer any relationship between the levels of a particular F6-specific IgG subclass and the infection or disease status.

Enhancement of alkaline phytase production in Pichia pastoris: influence of gene dosage, sequence optimization and expression temperature.

Supplementation of animal feed with phytases has proven to be an effective strategy to alleviate phosphorous contamination of soil and water bodies. The inability of non-ruminant animals to digest phytates in corn and soybeans contributes to environmental contamination. Alkaline phytase from lily pollen (LlALP) exhibits unique catalytic and thermal stability properties that could be useful as a feed supplement.

Oxidative stress and inflammatory responses of rat following acute inhalation exposure to iron oxide nanoparticles.

In this research, we investigated the toxicity responses of rat following a continuous 4 h inhalation exposure of only the head and nose to iron oxide nanoparticles (Fe(3)O(4) NPs, size = 15-20 nm). The rats for the investigation were exposed to a concentration of 640 mg/m(3) Fe(3)O(4) NPs. Markers of lung injury and proinflammatory cytokines (interleukin-1β, tumor necrosis factor-α, and interleukin-6) in bronchoalveolar lavage fluid (BALF) and blood, oxidative stress in lungs, and histopathology were assessed on 24 h, 48 h, and 14 days of postexposure periods.

Horizontal transmission of group B streptococcus in a neonatal intensive care unit.

The incidence of early-onset group B streptococcal (GBS) sepsis in the neonatal population has decreased substantially since the introduction of maternal intrapartum antibiotic prophylaxis and routine prenatal screening. However, these strategies have not reduced the incidence of late-onset GBS infections. Additional research pertaining to the transmission of late-onset GBS infections is required to develop effective preventive methods.

Mobile diabetes eye care: experience in developing countries.

The prevalence of diabetes in developing countries is on the increase and along with it the need to provide structured care to avoid the feared long term complications among them loss of vision and blindness due to diabetic retinopathy (DR). The biggest hurdle facing most developing countries is the lack of resources and trained manpower to both screen and treat the large number of people with DR. Countries also face the additional problem of unequal distribution of resources between the urban and rural areas.

Psychiatric advance directives: potential challenges in India.

The advance directive is a statement of an individual's preference for future treatment. The concept initially evolved in the context of end-of-life treatment decision making. Subsequently, in some countries, advance directives have been promoted in the care and treatment of people with serious mental disorders.

Catalysis by molecular iodine: a rapid synthesis of 1,8-dioxo-octahydroxanthenes and their evaluation as potential anticancer agents.

Molecular iodine facilitated the reaction of 5,5-dimethyl-1,3-cyclohexanedione with aromatic aldehydes in iso-propanol affording a variety of 1,8-dioxo-octahydroxanthenes in high yields. Most of the compounds synthesized showed good anti-proliferative properties in vitro against three cancer cell lines and 9-(2-hydroxyphenyl)-3,3,6,6-tetramethyl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione possessing a 2-hydroxy phenyl group at C-9 position was found to be promising. Further structure elaboration of the same compound and the crystal structure analysis and hydrogen bonding patterns of another compound that is, 9-(4-methoxyphenyl)-3,3,6,6-tetramethyl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione prepared by using this methodology is presented.

Two molecular weight species of thrombospondin-2 are present in bone and differentially modulated in fractured and nonfractured tibiae in a murine model of bone healing.

We report two immuoreactive species of thrombospondin-2 (TSP2), sized approximately 200 and 125 kDa, in the long bones of growing, but not skeletally mature, mice. In vitro osteoblasts secrete a 200-kDa species into the culture medium as early as day 3, and it appears in the cell-matrix layer by day 7. A 125-kDa species appears in the cell-matrix layer in parallel with mineralization; it is not detected in cell-conditioned medium.

Paradoxical role of C1561T glutamate carboxypeptidase II (GCPII) genetic polymorphism in altering disease susceptibility.

Glutamate carboxypeptidase II (GCPII) is predominantly expressed in brain, intestinal mucosa and prostate cancer in the form of three splice variants i.e. N-acetylated-α-linked acidic dipeptidase (NAALADase), folyl poly-γ-glutamate carboxypeptidase (FGCP) and prostate specific membrane antigen (PSMA) respectively.

In vitro and in vivo antifilarial activity evaluation of 3,6-epoxy [1,5]dioxocines: a new class of antifilarial agents.

A series of 3,6-epoxy [1,5]dioxocines were synthesized and evaluated for their antifilarial activity against adult parasites of human lymphatic filarial parasite Brugia malayi (sub-periodic strain) in vitro. Out of these, six compounds (4a-f) possessed improved in vitro anti-filarial activity and examples 4d and 4f were also found to be active in the in vivo experiments. These results demonstrate that 3,6-epoxy [1,5]dioxocines exhibits potent antifilarial activity and might be developed into a new class of antifilarial drug.
