12-Hydroxyeicosatetraenoic acid is the only enzymatically produced HETE increased under brain ischemia.

Hydroxyeicosatetraenoic acids (HETE) are dramatically increased under brain ischemia and significantly affect post-ischemic recovery. However, the exact mechanism of HETE increase and their origin under ischemia are poorly understood. HETE might be produced de novo through lipoxygenase (LOX) -dependent synthesis with possible esterification into a lipid storage pool, or non-enzymatically through free radical oxidation of esterified arachidonic acid (20:4n6).

Nephroprotective Effects of Mycophenolate Mofetil and Glibenclamide on Streptozotocin-induced Diabetic Renal Injury in Rats: An Experimental Study.

Diabetic renal injury is a microvascular complication associated with inflammation and oxidative stress, culminating in renal dysfunction. Conventionally, it is treated with hypoglycemic agents to address metabolic perturbations. However, the way to mitigate immunological, inflammation, and oxidative stress have seldom been studied.

Exogenous oxygen is required for prostanoid induction under brain ischemia as evidence for a novel regulatory mechanism.

Previously, we and others reported a rapid and dramatic increase in brain prostanoids (PG), including prostaglandins, prostacyclins, and thromboxanes, under ischemia that is traditionally explained through the activation of esterified arachidonic acid (20:4n6) release by phospholipases as a substrate for cyclooxygenases (COX). However, the availability of another required COX substrate, oxygen, has not been considered in this mechanism. To address this mechanism for PG upregulation through oxygen availability, we analyzed mouse brain PG, free 20:4n6, and oxygen levels at different time points after ischemic onset using head-focused microwave irradiation (MW) to inactivate enzymes in situ before craniotomy.

Analgesic Efficacy of Acupuncture on Chronic Pelvic Pain: A Systemic Review and Meta-Analysis Study.

Chronic pelvic pain (CPP) is the pain occurred in the pelvic region longer than six months. The monotherapy of medicine may not adequate for the pain management of CPP and multidisciplinary approaches have been more recommended. The aim of this study is to evaluate the pain management efficacy of acupuncture compared with a control group on CPP.

Antihistamine promotes electroacupuncture analgesia in healthy human subjects: A pilot study.

Background And Aim: We have previously reported that histamine H receptor antagonists facilitate electroacupuncture (EA) analgesia in experimental animals. In this pilot study, we sought to determine whether the histamine H receptor antagonist dexchlorpheniramine (DCPA) facilitates EA analgesia in healthy human subjects.

Experimental Procedure: Forty healthy subjects aged 20-30 years were randomly allocated to 1 of 4 groups: (1) sham EA at acupoints Zusanli (ST36) and Yanglingquan (GB34) (sham EA; n = 10); (2) EA at ST36 and GB34 (n = 10); (3) EA at ST36 and GB34 plus low-dose DCPA (2 mg, n = 10); (4) EA at ST36 and GB34 plus high-dose DCPA (4 mg, n = 10).

Electroacupuncture improves TBI dysfunction by targeting HDAC overexpression and BDNF-associated Akt/GSK-3β signaling.

Background: Acupuncture or electroacupuncture (EA) appears to be a potential treatment in acute clinical traumatic brain injury (TBI); however, it remains uncertain whether acupuncture affects post-TBI histone deacetylase (HDAC) expression or impacts other biochemical/neurobiological events.

Materials And Methods: We used behavioral testing, Western blot, and immunohistochemistry analysis to evaluate the cellular and molecular effects of EA at LI4 and LI11 in both weight drop-impact acceleration (WD)- and controlled cortical impact (CCI)-induced TBI models.

Results: Both WD- and CCI-induced TBI caused behavioral dysfunction, increased cortical levels of HDAC1 and HDAC3 isoforms, activated microglia and astrocytes, and decreased cortical levels of BDNF as well as its downstream mediators phosphorylated-Akt and phosphorylated-GSK-3β.

Understandings of acupuncture application and mechanisms.

Acupuncture involves the stimulation of acupoints, which are located at specific sites of the human body, by insertion of fine metal needles, followed by manipulation. Acupuncture has been proven to be an effective treatment in pain relief. Available evidence showed that acupuncture alleviates acute pain in conditions such as postoperative pain, acute back pain, labour pain, primary dysmenorrhea, tension-type headaches and migraines.

Antidiabetic Action of Mcy Protein: Studies on Gene Expression and Competitive Binding to Insulin Receptors.

Mcy protein, isolated from the fruits of Momordica cymbalaria, was shown to have antihyperglycemic, antihyperlipidemic activities along with renal as well as hepatoprotective activities in streptozotocin-induced diabetic rats. Mcy protein was shown to have insulin-like structure and/or function and/or insulin secretagogue activity. Hence, the present study was conducted to elucidate the molecular mechanism whereby Mcy protein elicits its therapeutic role and also to know whether the Mcy protein has any structural and functional similarity with insulin.

Electroacupuncture prevents cocaine-induced conditioned place preference reinstatement and attenuates ΔFosB and GluR2 expression.

Acupuncture has been used for treating drug addiction since the 1970s, but little is known about the mechanisms by which acupuncture affects drug cue-induced relapse. The transcription factor delta-FosB (ΔFosB) plays a critical role in behavior and pathology after chronic use of cocaine. ΔFosB regulates glutamate receptor signaling and dendritic spine morphology in animal models.

Evaluation of biochemical mechanisms of anti-diabetic functions of Anisomeles malabarica.

Anisomeles malabarica (AM) is an aromatic plant traditionally used for the treatment of diabetes mellitus in India. Following bioassay guided fractionation, we recently identified an active fraction of AM (AMAF, with potential mix of active principles) that showed significant antihyperglycemic and antihyperlipidemic activities. In addition, AMAF treatment improved insulin levels.

A Novel, Minimally Invasive Technique in the Management of a Large Cyst Involving the Maxilla in a Child: A Case Report.

The conservative management of large, odontogenic, developmental cysts involving the jaws in young children using the technique of decompression has become increasingly popular to reduce the incidence of morbidity associated with aggressive treatment modalities. The lack of development of a stock device has made clinicians to explore various possible and readily available materials to customize the devices. This paper highlights the use of a novel material to be used as a decompression device that is readily available and can be used with good patient compliance and a predictable outcome.

Anti-Diabetic Potential of the Leaves of Anisomeles malabarica in Streptozotocin Induced Diabetic Rats.

Background/aims: Diabetes mellitus is a pandemic metabolic disorder that is affecting a majority of populations in recent years. There is a requirement for new drugs that are safer and cheaper due to the side effects associated with the available medications.

Methods: We investigated the anti-diabetic activity of leaves of Anisomeles malabarica following bioactivity guided fractionation.

Adenovirus entry from the apical surface of polarized epithelia is facilitated by the host innate immune response.

Prevention of viral-induced respiratory disease begins with an understanding of the factors that increase or decrease susceptibility to viral infection. The primary receptor for most adenoviruses is the coxsackievirus and adenovirus receptor (CAR), a cell-cell adhesion protein normally localized at the basolateral surface of polarized epithelia and involved in neutrophil transepithelial migration. Recently, an alternate isoform of CAR, CAREx8, has been identified at the apical surface of polarized airway epithelia and is implicated in viral infection from the apical surface.

The PDZ3 domain of the cellular scaffolding protein MAGI-1 interacts with the Coxsackievirus and adenovirus receptor (CAR).

The Coxsackievirus and adenovirus receptor (CAR) is an essential cellular protein that is involved in cell-cell adhesion, protein trafficking, and viral infection. The major isoform of CAR is selectively sorted to the basolateral membrane of polarized epithelial cells where it co-localizes with the cellular scaffolding protein membrane-associated guanylate kinase with inverted domain structure-1 (MAGI-1). Previously, we demonstrated CAR interacts with MAGI-1 through a PDZ-domain dependent interaction.

Automated system for kinetic analysis of particle size distributions for pharmaceutically relevant systems.

Detailing the kinetics of particle formation for pharmaceutically relevant solutions is challenging, especially when considering the combination of formulations, containers, and timescales of clinical importance. This paper describes a method for using commercial software Automate with a stream-selector valve capable of sampling container solutions from within an environmental chamber. The tool was built to monitor changes in particle size distributions via instrumental particle counters but can be adapted to other solution-based sensors.

Probability-based compatibility curves for calcium and phosphates in parenteral nutrition formulations.

Background: The information content of the calcium phosphate compatibility curves for adult parenteral nutrition (PN) solutions may benefit from a more sophisticated statistical treatment. Binary logistic regression analyses were evaluated as part of an alternate method for generating formulation compatibility curves.

Materials And Methods: A commercial PN solution was challenged with a systematic array of calcium and phosphate concentrations.

Interactions between Parenteral Lipid Emulsions and Container Surfaces.

Objective: To evaluate the relationship between changes in emulsion globule size distributions and container uptake of lipid emulsions in total nutrient admixtures.

Methods: A total nutrient admixture was prepared from a commercial lipid emulsion, 20% ClinOleic®, separated into glass (borosilicate) and ethylene vinyl acetate (EVA) plastic containers, and then stored at ambient conditions for approximately 24 h. The large globule size distribution was monitored continuously for both containers, and the quantity of triglycerides associated with both containers was measured by liquid chromatography.

Prevalence of diabetes, metabolic syndrome, and cardiovascular risk factors in US Asian Indians: results from a national study.

Background: Although studies of immigrant Asian Indians in other countries show high rates of diabetes (DM), metabolic syndrome (MetS), and cardiovascular disease (CVD), no randomized, population-based studies of this rapidly growing ethnic group exist in the US.

Methods: The sample comprised 1038 randomly selected Asian Indian immigrants, aged 18 years and older at seven US sites. Prevalence of diabetes and MetS (age-adjusted and sex-adjusted means) was estimated and ANOVA was used to calculate gender and group differences (normoglycemia/impaired fasting glucose/diabetes) for CVD risk factors.

High-density lipoprotein subclass distribution in individuals of Asian Indian descent: the National Asian Indian Heart Disease Project.

Individuals of Asian Indian descent have significantly higher cardiovascular event rates as compared with other ethnic groups. The authors investigated the prevalence of metabolic disorders linked to coronary artery disease in an Asian Indian male population compared with non-Asian Indian males. Standard lipid measurements did not discriminate between groups, and the Asian Indian group exhibited less of the high coronary artery disease risk small low-density lipoprotein trait.

Early deaths with thrombolytic therapy for acute myocardial infarction in corticosteroid-dependent rheumatoid arthritis.

Intravenous thrombolytic therapy has become standard treatment for acute myocardial infarction (AMI). We describe three patients with long-standing seropositive rheumatoid arthritis (RA) on chronic corticosteroid therapy who experienced very early (1-6 h) mortality after the use of intravenous thrombolytic therapy for the treatment of AMI. All three patients likely experienced electromechanical dissociation (EMD).
