Prevention of Preterm Birth with Progesterone.

Gestational age at birth is a critical factor for perinatal and adulthood outcomes, and even for transgenerational conditions' effects. Preterm birth (PTB) (prematurity) is still the main determinant for infant mortality and morbidity leading cause of infant morbidity and mortality. Unfortunately, preterm birth (PTB) is a relevant public health issue worldwide and the global PTB rate is around 11%.

Genomic epidemiology of rifampicin ADP-ribosyltransferase (Arr) in the Bacteria domain.

Arr is an ADP-ribosyltransferase enzyme primarily reported in association with rifamycin resistance, which has been used to treat tuberculosis in addition to Gram-positive infections and, recently, pan-resistant Gram-negative bacteria. The arr gene was initially identified on the Mycolicibacterium smegmatis chromosome and later on Proteobacteria plasmids. This scenario raised concerns on the distribution and spread of arr, considering the Bacteria domain.

TriatoScore: an entomological-risk score for Chagas disease vector control-surveillance.

Background: Triatomine bugs transmit Chagas disease across Latin America, where vector control-surveillance is increasingly decentralized. Locally run systems often deal with highly diverse native-vector faunas-plus, in some areas, domestic populations of non-native species. Flexible entomological-risk indicators that cover native and non-native vectors and can support local decision-making are therefore needed.

Comparison of different chemical treatments of brush and flat carbon electrodes to improve performance of microbial fuel cells.

Anodes in microbial fuel cells (MFCs) can be chemically treated to improve performance but the impact of treatment on power generation has not been examined for different electrode base materials. Brush or flat anodes were chemically treated and then compared in identical two-chambered MFCs using the electrode potential slope (EPS) analysis to quantify the anode resistances. Flat carbon cloth anodes modified with carbon nanotubes (CNTs) produced 1.

Micro-Raman spectroscopy of lipid halo and dense-core amyloid plaques: aging process characterization in the Alzheimer's disease APPswePS1ΔE9 mouse model.

The deposition of amyloid plaques is considered one of the main microscopic features of Alzheimer's disease (AD). Since plaque formation can precede extensive neurodegeneration and it is the main clinical manifestation of AD, it constitutes a relevant target for new treatment and diagnostic approaches. Micro-Raman spectroscopy, a label-free technique, is an accurate method for amyloid plaque identification and characterization.

Application of Raman spectroscopy for characterization of the functional polarization of macrophages into M1 and M2 cells.

Macrophages are key cells in the immune inflammatory response that can be differentiated into M1 and M2 phenotypes. Polarization has a critical therapeutic value, especially in diseases in which an M1/M2 imbalance plays a pathophysiological role. Raman spectroscopy has proven to be a promising bioanalytical technique for discriminating different cell types.

A case of duodenal-type follicular lymphoma.

An 83-year-old female with history of silicosis was referred for upper endoscopy due to duodenal wall thickness detected in thoracic computer tomography (CT). Upper endoscopy revealed multiple small (1 to 5 mm), whitish polypoid lesions, involving a discrete portion of the descending part of the duodenum with 3 cm extension.

The role of the radiologist in the assessment of thoracic changes after radiotherapy.

Radiotherapy plays a central role in the palliative and curative treatment of neoplasms of the chest wall or intrathoracic structures. However, despite technical advances, radiotherapy can alter previously normal organs and tissues, those alterations presenting as various types of imaging findings. Post-radiation alterations must be promptly recognized by radiologists, in order to avoid confusion between complications of radiotherapy and the recurrence of a tumor.

Speckle filtering through nonlinear wave mixing.

Light scattering by disordered media is a ubiquitous effect. After passing through them, the light acquires a random phase, masking or destroying associated information. Filtering this random phase is of paramount importance to many applications, such as sensing, imaging, and optical communication, to cite a few, and it is commonly achieved through computationally extensive post-processing using statistical correlation.

Effect of late-onset epilepsy on cognitive functioning in patients with small vessel disease.

Autoimmune Responses in Oncology: Causes and Significance.

Specific anti-tumor immune responses have proven to be pivotal in shaping tumorigenesis and tumor progression in solid cancers. These responses can also be of an autoimmune nature, and autoantibodies can sometimes be present even before the onset of clinically overt disease. Autoantibodies can be generated due to mutated gene products, aberrant expression and post-transcriptional modification of proteins, a pro-immunogenic milieu, anti-cancer treatments, cross-reactivity of tumor-specific lymphocytes, epitope spreading, and microbiota-related and genetic factors.
