Identification of P-glycoprotein co-fractionating proteins and specific binding partners in rat brain microvessels. - Journal of neurochemistry
Drug delivery to the brain for the treatment of pathologies with a CNS component is a significant clinical challenge. P-glycoprotein (PgP), a drug efflux pump in the endothelial cell membrane, is a major factor in preventing therapeutics from crossing the blood-brain barrier (BBB). Identifying PgP regulatory mechanisms is key to developing agents to modulate PgP activity. Previously, we found that PgP trafficking was altered concomitant with increased PgP activity and disassembly of high molecular weight PgP-containing complexes during acute peripheral inflammatory pain. These data suggest that PgP activity is post-translationally regulated at the BBB. The goal of the current study was to identify proteins that co-localize with PgP in rat brain microvessel endothelial cell membrane microdomains and use the data to suggest potential regulatory mechanisms. Using new density gradients of microvessel homogenates, we identified two unique pools (1,2) of PgP in membrane fractions. Caveolar constituents, caveolin1, cavin1, and cavin2, co-localized with PgP in these fractions indicating the two pools contained caveolae. A chaperone (Hsc71), protein disulfide isomerase and endosomal/lysosomal sorting proteins (Rab5, Rab11a) also co-fractionated with PgP in the gradients. These data suggest signaling pathways with a potential role in post-translational regulation of PgP activity at the BBB. This model depicts two types of P-glycoprotein (PgP)-containing caveolae. Rat brain microvessels contain two unique pools of PgP that are of different densities. Each pool co-fractionates with three caveolar proteins suggesting there are two populations of caveolae that contain PgP. The two caveolar populations differ in density indicating they have a different structure, lipoprotein content or intracellular location. Our model includes two newly identified PgP-binding partners, Hsc71 and protein disulfide isomerase, in rat brain microvessels.© 2015 International Society for Neurochemistry.
Adventures within the speckled band: heterogeneity, angiogenesis, and balanced inflammation in the tuberculous granuloma. - Immunological reviews
Recent work in a variety of animal models, including mice, zebrafish, and macaques, as well as in humans, has led to a reassessment of several tenets of mycobacterial infection. In this review, we describe new findings about the composition and dynamics of the tuberculous granuloma, the central host structure in mycobacterial infection, as well as inflammatory mediators that drive a successful anti-microbial response on one hand and pathological inflammation on the other. We highlight granuloma heterogeneity that emerges in the context of infection, the functional consequences of angiogenesis in tuberculous granulomas, and data that balanced inflammation in humans, with a central role for tumor necrosis factor, appears to play a key role in optimal defense against mycobacterial infection. These findings have suggested new and specific host-directed therapies that await further clinical exploration.© 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
Visual feedback system to reduce errors while operating roof bolting machines. - Journal of safety research
Operators of roof bolting machines in underground coal mines do so in confined spaces and in very close proximity to the moving equipment. Errors in the operation of these machines can have serious consequences, and the design of the equipment interface has a critical role in reducing the probability of such errors.An experiment was conducted to explore coding and directional compatibility on actual roof bolting equipment and to determine the feasibility of a visual feedback system to alert operators of critical movements and to also alert other workers in close proximity to the equipment to the pending movement of the machine. The quantitative results of the study confirmed the potential for both selection errors and direction errors to be made, particularly during training.Subjective data confirmed a potential benefit of providing visual feedback of the intended operations and movements of the equipment.This research may influence the design of these and other similar control systems to provide evidence for the use of warning systems to improve operator situational awareness.Published by Elsevier Ltd.
Type 2 Diabetes and its Characteristics during Ramadan in Dhahira Region, Oman. - Oman medical journal
The main objective of this study is to illustrate the various characteristics including care of patients and changes in lifestyle of type 2 diabetics during Ramadan in Dhahira region, Oman.This was a hospital-based study conducted during the month of Ramadan in 2006. Of the 453 recruited, 334 (73.7%) with complete data were analyzed. Student t test was used for comparison of means and Chi-square test for proportions.We analyzed 334 patients with type 2 diabetes. The common complication associated with diabetes was coronary artery disease (19.5%) and nearly 60% of the study subjects had hypertension as co-morbidity. There was little or no change in the lifestyle activities and Insulin/Oral AntiDiabetic Drug (OAD) doses during Ramadan. Majority of diabetics had poorly controlled Fasting Blood Sugar (FBS) and Body Mass Index (BMI). The overall mean weight change was -0.49 ± 1.54 SD. There was a significant weight loss during Ramadan (p<0.05).The large proportions of uncontrolled type 2 diabetes patients in our region represent a challenge to our physicians during Ramadan. There is a need to improve diabetic management and intensive education before fasting. Clear guidelines for diabetic management including uncontrolled diabetics during Ramadan are essential in Oman.
An efficient synthesis of a dual PPAR alpha/gamma agonist and the formation of a sterically congested alpha-aryloxyisobutyric acid via a Bargellini reaction. - The Journal of organic chemistry
A practical synthesis of benzisoxazole 1 and its conversion to alpha-aryloxyisobutyric acid 2 using 1,1,1-trichloro-2-methyl-2-propanol (chloretone) was developed. Benzisoxazole 1 was formed in high yields by the action of either methanesulfonyl chloride/base upon intermediate oxime 8 or with thionyl chloride/base, which initially forms cyclic sulfite 10. A highly reactive, short-lived intermediate derived from chloretone was detected by ReacIR and its half-life determined to be approximately 5 min. Reaction conditions for the Bargellini reaction were developed that resulted in a 95% yield of 2 from the reaction of highly hindered phenol 1 with chloretone hemihydrate and powdered NaOH in acetone. Thus highly hindered alpha-aryloxyisobutyric acids can be made in a single step in high yield.
Synthesis of a potent hNK-1 receptor antagonist via an SN2 reaction of an enantiomerically pure alpha-alkoxy sulfonate. - Organic letters
The concise synthesis of a stereochemically rich hNK-1 receptor antagonist is described. The synthesis is highlighted by an S(N)2 reaction of an enantiomerically pure alpha-alkoxy sulfonate (orthogonally protected butane triol), which was prepared by utilizing salen-mediated hydrolytic kinetic resolution technology. A stereocontrolled acetalization was employed to connect two enantiomerically pure fragments with a high degree of diastereoselectivity.
A concise synthesis of a novel antiangiogenic tyrosine kinase inhibitor. - The Journal of organic chemistry
An efficient synthesis of the potent KDR inhibitor 3-[5-[[4-(methylsulfonyl)-1-piperazinyl]methyl]-1H-indole-2-yl]quinolin-2(1H)-one (1) is described. The process features a noncryogenic indole boronation and a dicyclohexylamine-mediated Suzuki coupling.
Stereoselective synthesis of a potent thrombin inhibitor by a novel P2-P3 lactone ring opening. - The Journal of organic chemistry
The concise synthesis of a potent thrombin inhibitor was accomplished by a mild lactone aminolysis between an orthogonally protected bis-benzylic amine and a diastereomerically pure lactone. The lactone was synthesized by the condensation of l-proline methyl ester with an enantiomerically pure hydroxy acid, which in turn was synthesized by a highly stereoselective (>500:1 er) and productive (100,000:1, S/C) enzymatic reduction of an alpha-ketoester. In addition, a second route to the enantiomerically pure lactone was accomplished by a diastereoselective ketoamide reduction.
Comparison of severe life stress in depressed mothers and non-mothers: do children matter? - Depression and anxiety
Given the high rates of maladjustment among children of depressed mothers, parenting is likely to cause significant life stress in this population, potentially worsening the course of mothers' depression. The present study is a comparison of severe life stress in 38 mothers and 62 non-mothers receiving treatment for recurrent major depression. Life stress was assessed using the Life Events and Difficulties Schedule [Brown and Harris, 1978a]. We hypothesized that mothers would evidence a greater number of severe life events and marked difficulties both in the year prior to the onset of their depressive index episode and in the time period following the onset of their current depressive episode. Prior to depression onset, mothers reported a significantly greater number of entrapping difficulties, but not marked difficulties, severe events, entrapping events, or humiliating events. However, following the onset of depression, mothers experienced a significantly greater number of severe events, entrapping events, marked difficulties, and entrapping difficulties, but not humiliating events. Mothers' elevated levels of stress were attributable to child-related stress, predominantly related to children's psychological and behavioral problems. Our findings suggest that comprehensive treatment for mothers with major depression needs to address their parenting style and any psychological problems experienced by their children.
Assessment of life stress in adolescents: self-report versus interview methods. - Journal of the American Academy of Child and Adolescent Psychiatry
To compare the investigator-based Life Events and Difficulties Schedule (LEDS) with a self-report measure (Life Events Checklist [LEC]) for the purpose of measuring life stress in adolescents with and without a diagnosis of major depressive disorder (MDD).Adolescents (aged 13-18 years) with a recent episode of MDD based on DSM-III-R (n = 35) and normal controls free of any Axis I lifetime psychiatric disorder (n = 35) were assessed using both the LEC and the LEDS.Both measures predicted membership in the depressed and nondepressed groups of adolescents. Adolescents in the depressed group were more likely to report a severe event on the LEDS (97%) than adolescents in the nondepressed group (66%) (p = .001). Similarly, subjects in the depressed group endorsed a greater number of negative events (mean = 8.1) on the LEC than subjects in the nondepressed group (mean = 3.0) (p = .0001). An examination of potential provoking agents for episodes of major depression revealed that the LEC captured only 32% of preonset severe events and 36% of preonset major difficulties identified by the LEDS.Interpreted in light of relative advantages and disadvantages, the results suggest that checklist and interview measures each have distinct advantages depending on the purpose for which they are being used.
