MPK9 and MPK12 function in SA-induced stomatal closure in Arabidopsis thaliana.

Salicylic acid (SA) induces stomatal closure sharing several components with abscisic acid (ABA) and methyl jasmonate (MeJA) signaling. We have previously shown that two guard cell-preferential mitogen-activated protein kinases (MAPKs), MPK9 and MPK12, positively regulate ABA signaling and MeJA signaling in Arabidopsis thaliana. In this study, we examined whether these two MAPKs are involved in SA-induced stomatal closure using genetic mutants and a pharmacological, MAPKK inhibitor.

Socio-demographic Determinants of Compliance among Type 2 Diabetic Patients in Abha, Saudi Arabia.

Background And Objectives: Saudi Arabia has one of the highest prevalence of diabetes. This study was conducted with the following objectives: (1) To study the socio-demographic profile of diabetic patients in Abha. (2) To find the socio-demographic determinants of compliance among diabetic patients in Abha.

MAP kinases, MPK9 and MPK12, regulate chitosan-induced stomatal closure.

Chitosan (CHT)-induced stomatal closure was inhibited by an MAPKK inhibitor, PD98059, and was impaired in mpk9 mpk12 but not in mpk9 or mpk12. CHT induced the production of reactive oxygen species, cytosolic alkalization, and cytosolic Ca(2+) oscillation in mpk9 mpk12. These results suggest that MPK9 and MPK12 are involved in CHT-induced stomatal closure.

Role of Toll-like receptors in host responses to a virulence antigen of Streptococcus mutans expressed by a recombinant, attenuated Salmonella vector vaccine.

In the present study, we investigated the role of Toll-like receptors (TLRs) in host responses to the saliva-binding region (SBR) of Streptococcus mutans expressed by a recombinant, attenuated Salmonella vaccine. C57BL/6 wild type (wt), TLR2-/-, TLR4-/- and MyD88-/- mice were immunized by the intranasal route on days 0, 18 and boosted on day 98 with Salmonella typhimurium BRD 509 containing a plasmid encoding SBR. Serum and saliva samples were collected throughout the experiment and assessed for antibody activity by ELISA.

Frequency distribution of F-latencies (DFL) has physiological significance and gives distribution of conduction velocity (DCV) of motor nerve fibres with implications for diagnosis.

On electrical stimulation of a peripheral motor nerve, a delayed and reduced F-response is obtained, which is known to occur due to random backfiring of a few percent of the motor nerve fibres at the spinal end after antidromic conduction. F-latencies obtained from multiple stimulations vary in latency, size and shape because of this randomness. We hypothesised that, being a random process, recruitment of fibres for F-response would depend on the distribution of conduction velocity (DCV) for motor nerve fibres directly, and therefore, a frequency distribution of F-latencies (DFL) from such multiple F-responses would be an approximate mirror image of DCV, latency being inversely proportional to velocity.

Anthropometric characteristics of elderly people: observations at a large diarrheal hospital in Dhaka, Bangladesh.

There is a lack of evidence-based information to assist health policy makers in preparing for appropriate health, nutrition, and social-support guidelines for the elderly in Bangladesh. We examined selected indicators of the nutritional status of elderly people attending the Dhaka Hospital of ICDDR,B, Dhaka, Bangladesh. The population constituted of 1,196 individuals (718 men and 478 women), aged 60 to 106 years, who attended the hospital between 1 January 1993 and 31 December 2003.

Immunogenicity of Salmonella vector vaccines expressing SBR of Streptococcus mutans under the control of a T7-nirB (dual) promoter system.

The purpose of the present study was to determine if a Salmonella vector expressing the cloned saliva-binding region (SBR) of Streptococcus mutans or SBR linked to the A2 and B subunits of cholera toxin (CTA2/B) under the control of both the T7 and nirB promoters (T7-nirB dual promoter) was more effective in inducing mucosal and systemic anti-SBR antibody responses than Salmonella clones expressing the same antigens but under the control of either the nirB or T7 promoter. Mice were immunized by the intranasal route on days 0, 18 and 320 with Salmonella enterica serovar Typhimurium strain BRD 509 containing one of six plasmids encoding SBR or SBR-CTA2/B under the control of the T7-nirB, T7, or nirB promoter. Serum, saliva and vaginal wash samples were collected throughout the experiment and assessed for antibody activity by ELISA.

Low risk of hemolytic uremic syndrome after early effective antimicrobial therapy for Shigella dysenteriae type 1 infection in Bangladesh.

Background: Hemolytic uremic syndrome (HUS) may complicate up to 15% of cases of Shiga toxin (Stx)-expressing enterohemorrhagic Escherichia coli (STEC) O157:H7 infections in children. Administration of antimicrobials has been reported to increase the risk of STEC-associated HUS by >10-fold, presumably by increasing the expression and release of Stx by dying STEC bacteria. Shigella dysenteriae type 1 also expresses Stx.
