Ocorrência e caracterização da tuberculose em caprinos leiteiros criados no estado de Pernambuco

Pesquisa Veterinária Brasileira, 2012
Acreditou-se durante muito tempo que a espécie caprina era resistente à infecção por Mycobacterium bovis, porém tal hipótese foi desconsiderada quando relatos da enfermidade surgiram em vários países.

Green synthesis of silver nanoparticles using Curcuma longa flower extract and antibacterial activity [PDF]

arXiv, 2023
Silver nanoparticles (AgNP's) possess inherent biological potentials that have obliged an alternative, eco-friendly, sustainable approach to "Green Synthesis." In the present study, we synthesized Green Silver Nanoparticles (GAgNP's) using Curcuma longa L. (C. longa) flower extract as a reducing and capping agent.

The Milky Way's Stellar Disk [PDF]

Astron. Astrophys. Rev. 21:61,2013, 2013
A suite of vast stellar surveys mapping the Milky Way, culminating in the Gaia mission, is revolutionizing the empirical information about the distribution and properties of stars in the Galactic stellar disk. We review and lay out what analysis and modeling machinery needs to be in place to test mechanisms of disk galaxy evolution and to stringently ...

The Recent Development in the Diagnosis of Mycobacterium tuberculosis

Smart Medicine, Volume 4, Issue 2, June 2025.
Mycobacterium tuberculosis (MTB) remains a major global health challenge due to slow, low‐sensitivity traditional diagnostics. Rapid, highly sensitive point‐of‐care tests are critical for timely diagnosis and treatment, reducing transmission. This study reviews the evolution of MTB diagnostic tests, emphasizing advancements and addressing accessibility

Label-free optical vibrational spectroscopy to detect the metabolic state of M. tuberculosis cells at the site of disease [PDF]

, 2017
Tuberculosis relapse is a barrier to shorter treatment. It is thought that lipid rich cells, phenotypically resistant to antibiotics, may play a major role. Most studies investigating relapse use sputum samples although tissue bacteria may play an important role. We developed a non-destructive, label-free technique combining wavelength modulated Raman (

Galactic rotation in Gaia DR1 [PDF]

Mon. Not. R. Astron. Soc. Lett. 468 (1): L63-L67 (2017), 2016
The spatial variations of the velocity field of local stars provide direct evidence of Galactic differential rotation. The local divergence, shear, and vorticity of the velocity field---the traditional Oort constants---can be measured based purely on astrometric measurements and in particular depend linearly on proper motion and parallax.

Human Tuberculosis Caused by Mycobacterium bovis in the United States, 2006-2013.

Clinical Infectious Diseases, 2016
BACKGROUND Using genotyping techniques that have differentiated Mycobacterium bovis from Mycobacterium tuberculosis since 2005, we review the epidemiology of human tuberculosis caused by M.

On the impact of Masking and Blocking Hypotheses for measuring efficacy of new tuberculosis vaccines [PDF]

arXiv, 2015
Over the past 60 years, the Mycobacterium bovis bacille Calmette-Gu\'erin (BCG) has been used worldwide to prevent tuberculosis (TB). However, BCG has shown a very variable efficacy in different trials, showing a wide range of protection in adults against pulmonary TB.

Oligonucleotide‐Based Modulation of Macrophage Polarization: Emerging Strategies in Immunotherapy

Immunity, Inflammation and Disease, Volume 13, Issue 5, May 2025.
Receptors and signaling pathways that are involved in M1/M2 polarization. This schematic illustrates how different surface receptors (including TLRs, IFNAR/IFNGR, IL‐4/IL‐13R, IL‐10R, and the Notch receptor) and their downstream signaling cascades coordinate the polarization of macrophages into M1 or M2 phenotypes.
