Publication date: Available online 9 December 2019Source: Microbiological ResearchAuthor(s): Vivek Vinod, Sukhithasri Vijayrajratnam, Anil Kumar Vasudevan, Raja BiswasAbstractBacterial cell surface adhesins play a major role in facilitating host colonization and subsequent establishment of infection. The surface of Mycobacterium tuberculosis, owing to the complex architecture of its cell envelope, expresses numerous adhesins with varied chemical nature, including proteins, lipids, lipoproteins, glycoproteins and glycopolymers. Studies on mycobacterial adhesins show that they bind with multifarious host receptors and extrac...

Abstract This paper presents the first comprehensive report on traditional uses of medicinal shrubs of Rawalakot city, district Poonch, Azad Jammu and Kashmir, Pakistan. Ethobotanical data obtained from 120 informants were analyzed by relative frequency citation, use value, family use value, informant consensus factor, fidelity level and Jaccard index. In total, 41 shrubs belonging to 24 families and 34 genera were documented. Rosaceae was reported the most dominant family in the area (six species) and Berberidaceae showed maximum family use value (0.68). Leaves (35%) and fruits (33%) were the most commonly used plant part...

Mycobacterium tuberculosis (Mtb) resides in a quarter of the world's population and is the causative agent for tuberculosis (TB), the most common infectious reason of death in humans today. Although cellular immunity has been firmly established in the control of Mtb, there is growing evidence that antibodies may also modulate the infection. More specifically, certain antibody features are associated with inflammation and are divergent in different states of human infection and disease. Importantly, TB impacts not just the healthy but also those with chronic conditions. While HIV represents the quintessential comorbid condi...

AbstractThis paper presents a probable case of subligamentous tuberculous spondylitis (STBS), a rare form of extra ‐pulmonary tuberculosis, diagnosed in the skeleton of a middle‐aged male discovered in the ossuary of the Franciscan crypt of the St. Anthony and St. Eusebius church, which lies in north‐western Italy. The skeleton can be dated back between the 17th‐19th centuries. This rare type of tubercul osis was identified in the thoracic and lumbar spine, with no further evidences at the level of the cranial and other postcranial bones. The concomitance of osteoclastic and osteoblastic activities, scalloping, rea...

ConclusionThis study demonstrates that ESAT6 bound with TLR2 can activate iNOS/NO and ROS signalings to reduce the trimethylation of H3K27 resulting in the increment of EMMMs expression that is beneficial to the transition of macrophages into epithelioid macrophages. However, hypoxia can inhibit this transition event. This study has provided new evidence of pathogenesis of granuloma caused by Mtb and also proposed new ideas for the treatment of TB.

Bilateral lung parenchymal involvement is seen in infective as well as noninfective conditions, appearing as focal or diffuse lung disease. PET/CT with FDG helps in characterization (increased glucose utilization is seen by both inflammatory and neoplastic cells). In this article, we describe the spectrum of patterns of FDG uptake and associated CT changes involving bilateral lung parenchyma. Benign conditions described are aspiration pneumonia; pulmonary toxicity by bleomycin; infections, namely, sarcoidosis, miliary pulmonary tuberculosis, and pulmonary nocardiosis; and inflammatory conditions such as pulmonary Langerhan...

CONCLUSION: During the last century, AADRs among males declined more slowly than among females. Although the gap diminished in recent decades, exploration of social and behavioral factors may inform interventions that could further reduce death rates among males.

Authors: Cerrone M, Bracchi M, Wasserman S, Pozniak A, Meintjes G, Cohen K, Wilkinson RJ Abstract Introduction: Antiretroviral and anti-tuberculosis (TB) drugs are often co-administered in people living with HIV (PLWH). Early initiation of antiretroviral therapy (ART) during TB treatment improves survival in patients with advanced HIV disease. However, safety concerns related to clinically significant changes in drug exposure resulting from drug-drug interactions, development of overlapping toxicities and specific challenges related to co-administration during pregnancy represent barriers to successful combined tre...

Publication date: 15 February 2020Source: Journal of Molecular Structure, Volume 1202Author(s): Jamelah S. Al-Otaibi, Y. Sheena Mary, Stevan Armaković, Renjith ThomasAbstractThree cocrystals of pyrazinamide (PYZ) with 2,4-dihydroxy benzoic acid (2,4HBA-PYZ), 2,6-dihydroxybenzoic acid (2,6HBA-PYZ) and 3,5-dihydroxybenzoic acid (3,5HBA-PYZ) are investigated by computational simulations. DFT calculations have been performed in order to understand the reactive properties of molecules that constitute the cocrystals. These calculations were followed by symmetry-adapted perturbation theory (SAPT) simulations to understand the in...

In this study we analysed the clinical profile of meningoencephalitis and its clinical outcome. METHODS: Fifty adults diagnosed with meningoencephalitis from July 2014 to July 2015 in a tertiary care hospital in South India were studied prospectively and their clinical presentation, aetiology and outcome were analysed. RESULTS: Among 50 patients, 33 (66%) were male; 39 (78%) were
