The differential diagnostic utility of the social communication questionnaire in mild intellectual disability and autism spectrum disorder: a case control study.

Objectives: This study investigated the utility of specific predictive and discriminative items within the Social Communication Questionnaire (SCQ) for distinguishing between autism spectrum disorder (ASD), intellectual disability (ID), and co-occurring ASD + ID in children.

Methods: A total of 137 children aged 4 to 12 years (52 typically developing (TD), 34 ASD, 26 ID, 25 ASD + ID) were included in the study. Cognitive development assessments were conducted for the ASD, ID, and ASD + ID groups in suitable cases.

Recombinant outer membrane protein Q and putative lipoprotein from Bordetella pertussis inducing strong humoral response were not protective alone in the murine lung colonization model.

Despite high vaccination coverage after introduction of whole cell (wP) and acellular pertussis (aP) vaccines, pertussis resurgence has been reported in many countries. aP vaccines are commonly preferred due to side effects of wP vaccines and formulated with aluminum hydroxide (Alum), which is not an effective adjuvant to eliminate Bordetella pertussis. Low efficiency of current aP vaccines is thought to be the main reason for the resurgence for which newer generation aP vaccines are needed.

Antibiotics: Pharmacokinetics, toxicity, resistance and multidrug efflux pumps.

The discovery of penicillin followed by streptomycin, tetracycline, cephalosporins and other natural, semi-synthetic and synthetic antimicrobials completely revolutionized medicine by reducing human morbidity and mortality from most of the common infections. However, shortly after they were introduced to clinical practice, the development of resistance was emerged. The decreasing interest from antibiotic industry in spite of rapid global emergence of antibiotic resistance is a tough dilemma from the pointview of public health.

Immunogenicity and protective efficacy of recombinant iron superoxide dismutase protein from Bordetella pertussis in mice models.

Whooping cough (pertussis) is a highly contagious respiratory infection caused by Bordetella pertussis. Although availability of effective pertussis vaccines reportedly decreases the incidence of the disease, B. pertussis circulation in populations has not been eliminated.

Impaired vasomotor function induced by the combination of hypertension and hypercholesterolemia.

Although it is well known that endothelial function is compromised in the presence of either hypertension (HTN) or hypercholesterolemia (HCh), less is known about whether and how the combination of these risk factors (HTN+HCh) results in impaired endothelium-dependent dilation (EDD). The aims of this study were to evaluate the influence of HTN+HCh on vasomotor function and to identify the mechanisms that underlie the altered vascular reactivity elicited by HTN+HCh. Endothelium-dependent and -independent vasomotor responses of aortic vessels were studied in mice with diet-induced HCh and/or HTN induced by chronic administration of either angiotensin II (AngII) or deoxycorticosterone acetate-salt.

Role of tumor necrosis factor-α in the extraintestinal thrombosis associated with colonic inflammation.

Background: Inflammatory bowel diseases (IBDs) are associated with a hypercoagulable state and an increased risk of thromboembolism, with accelerated thrombus formation occurring both within the inflamed bowel and in distant tissues. While the IBD-associated prothrombogenic state has been linked to the inflammatory response, the mediators that link inflammation and thrombosis remain poorly defined. The objective of this study was to assess the role of tumor necrosis factor alpha (TNF-α) in the enhanced extraintestinal microvascular thrombosis that accompanies colonic inflammation.

Selectin-mediated recruitment of bone marrow stromal cells in the postischemic cerebral microvasculature.

Background And Purpose: The therapeutic potential of bone marrow stromal cells (BMSCs) has been demonstrated in different models of stroke. Although it is well established that BMSCs selectively migrate to the site of brain injury, the mechanisms underlying this process are poorly understood. This study addresses the hypothesis that selectins mediate the recruitment of BMSCs into the postischemic cerebral microvasculature.

Role of coagulation factors in cerebral venous sinus and cerebral microvascular thrombosis.

Objective: The objective of this study was to define the relative contributions of three major pro- and anti-coagulation pathways (heparin-antithrombin, protein C, and tissue factor (TF)) in the thrombogenic responses that occur in large and small vessels of the brain.

Methods: Cerebral venous sinus thrombosis was induced by topical application of FeCl3 on the superior sagittal sinus, while photoactivation of fluorescein was used to induce thrombus formation in cerebral microvessels. Heparin, activated protein C (APC), and antibodies to either APC or TF were used to assess thrombogenesis in wild-type mice.

Roles of inflammation and the activated protein C pathway in the brain edema associated with cerebral venous sinus thrombosis.

Background And Purpose: Increased blood-brain barrier (BBB) permeability, brain edema, and hemorrhage are important consequences of cerebral venous sinus thrombosis (CVST). The objective of this study was to define the role of the protein C pathway in the BBB permeability and edema elicited by experimental CVST. The role of neutrophil recruitment was also evaluated.

Role of the protein C pathway in the extraintestinal thrombosis associated with murine colitis.

Background & Aims: Chronic inflammatory bowel diseases (IBD) are associated with an increased risk for thromboembolism. Although thrombosis is known to contribute to the morbidity and mortality of patients with IBD, the underlying mechanisms that contribute to the genesis of a hypercoagulable state during intestinal inflammation remain poorly defined. The objective of this study was to determine whether the protein C pathway contributes to the enhanced extraintestinal thrombosis that is associated with dextran sodium sulfate (DSS)-induced colitis in mice.
