Lipid rafts can form in the inner and outer membranes of Borrelia burgdorferi and have different properties and associated proteins

This article is protected by copyright. All rights reserved. The presence of cholesterol glycolipids in the membranes of Borrelia burgdorferi was detected and characterized by biophysical and biochemical approaches.  Cholesterol glycolipids are present in both the outer and inner membranes, but are different in composition and their ability to form lipid rafts and in their associated proteins.

Conclusions: We suggest that NLR, PLR, CRP, ESR, and bilirubin can be used in clinical practice for prediction of CVT in suspected patients as they are inexpensive parameters and widely available. However, further large-scale studies are required to confirm this relationship.RESUMEN la trombosis de la vena cerebral (CVT) es una causa rara pero grave de accidente cerebrovascular agudo. La inflamaci ón es un factor etiológico hipotético en CVT. Objetivo: El objetivo de este estudio fue evaluar los niveles de marcadores inflamatorios en pacientes con CVT y compararlos con los sujetos sanos. Métodos...

ConclusionVitamin D Deficiency was prevalent in both males and females across different age groups in the citizens of Saudi. Because of the connection between Vitamin D Deficiency and main chronic disease, it is necessary to emphasize the need to recognize Vitamin D Deficiency screening for risk factors. It may be reasonable for the nutritionists, nurses, and physicians, to encourage the community on approaches to enhance dietary Vitamin D or suggest supplementation.

This study aims at synthesizing novel di-morpholine 1,3,5-triazine derivatives as antidiabetic agent via inhibition of dipeptidyl peptidase-4 (DPP-4). The molecules were developed via sequential nucleophilic reaction to afford target derivatives 5(a –f) and subsequently tested for inhibitory potency against DPP iso-enzymes, such as DPP-4, DPP-8, and DPP-9. The in vitro inhibition assay suggested that these derivatives prominently and selectively inhibit DPP-4 over ­DPP-8 and DPP-9. These molecules also showed no presence of cardiotoxicity, a s confirmed by no activity against human Ether-à-go-go related ge...

Abstract Co-existing disordered and ordered (raft) membrane domains exist in Borrelia burgdorferi, the causative agent of Lyme disease. However, although B. burgdorferi contains cholesterol lipids, it lacks sphingolipids-a crucial component of rafts in eukaryotes. To define the principles of ordered lipid domain formation in Borrelia, the domain forming properties of vesicles composed of its three major lipids, acylated cholesteryl galactoside (ACGal), monogalactosyl diacyglycerol (MGalD), and phosphatidylcholine (PC) and/or their mixtures were studied. Anisotropy and fluorescence resonance energy transfer me...

Hey, Sugar, pay no attention to the man behind the curtain. Today, the Journal of the American Medical Association dropped an alleged bombshell when it disclosed that the sugar industry lobby influenced research on coronary heart disease by effectively bribing Harvard researchers to promote the theory that dietary fat, and not sugar, causes heart disease. The story is trending on Facebook at this very moment, and the JAMA Facebook post states that "Policymaking committees should consider giving less weight to food industry-funded studies, and include mechanistic and animal studies as well as studies appraising the ...

Wormley, J. Seshu Lyme disease (LD) is a systemic disorder caused by Borrelia burgdorferi. Lyme spirochetes encode for a functional 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGR EC serving as a rate limiting enzyme of the mevalonate pathway that contribute to components critical for cell wall biogenesis. Statins have been shown to inhibit B. burgdorferi in vitro. Using a mouse model of Lyme disease, we fou...

In this study, the bacterial CAP domain structure was analyzed and compared with the previously solved crystal structures of representative CAPs, and the function of BB0689 was examined. To determine the potential function of BB0689 and ascertain whether the functions that have been attributed to the CAP domain proteins are conserved, the binding of previously reported CAP domain interaction partners was analyzed, and the results suggested that BB0689 has a unique function that is yet to be discovered.
