[Q]: Context: Given the high prevalence of obesity and noncommunicable diseases in Mexico and the key role of dietary quality in these conditions, it is important to determine Mexicans' adherence to dietary recommendations.", 'Our aim was to estimate the percentage of the Mexican population who adhere to dietary recommendations for key food groups.', 'We analyzed 7983 participants aged ≥5 y from the nationally representative Mexican National Health and Nutrition Survey 2012. Dietary intake data were collected by using one 24-h recall and a repeated 24-h recall in 9% of the sample. We used the National Cancer Institute method for episodically consumed foods, which uses a 2-part (probability and amount) mixed regression model to estimate the usual intake distribution and its association with sociodemographic variables.', 'For the food groups that are encouraged, only 1-4% of the population (range across sex and age groups) reached the recommended intake of legumes, 4-8% for seafood, 7-16% for fruit and vegetables, and 9-23% for dairy. For food groups that are discouraged, only 10-22% did not exceed the recommended upper limit for sugar-sweetened beverages, 14-42% for high saturated fat and/or added sugar (HSFAS) products, and 9-50% for processed meats, whereas the majority (77-93%) did not exceed the limit for red meat. A lower proportion of adolescents than children and adults adhered to recommendations for several food groups. Participants with higher socioeconomic status (SES) and living in urban areas consumed more (probability of consuming and/or amount consumed) fruit and vegetables, dairy, and HSFAS products, but they consumed fewer legumes than those of lower SES and living in rural areas.
Answer: These results reveal the poor dietary quality of the Mexican population and the urgent need to shift these habits. If current intakes continue, the burden of disease due to obesity and noncommunicable chronic diseases will likely remain elevated in the Mexican population.

[Q]: Context: Bone marrow stromal cell antigen 2 (BST2), also known as tetherin, HM1.24 or CD317 represents a type 2 integral membrane protein, which has been described to restrict the production of some enveloped viruses by inhibiting the virus release from the cell surface. This innate antiviral mechanism is counteracted by the HIV-1 viral factor Vpu, targeting BST2 for cellular degradation. Since antiviral BST2 activity has been mainly confirmed by in vitro data, we investigated its role in vivo on the disease progression using the SIV/macaque model for AIDS. We determined BST2 expression in PBMC and leukocyte subsets of uninfected and SIV-infected rhesus macaques by real-time PCR and flow cytometry and correlated it with disease progression and viral load.', 'Compared to pre-infection levels, we found increased BST2 expression in PBMC, purified CD4(+) lymphocytes and CD14(+) monocytes of SIV-infected animals, which correlated with viral load. Highest BST2 levels were found in progressors and lowest levels comparable to uninfected macaques were observed in long-term non-progressors (LTNPs). During acute viremia, BST2 mRNA increased in parallel with MX1, a prototype interferon-stimulated gene. This association was maintained during the whole disease course.
Answer: The detected relationship between BST2 expression and viral load as well as with MX1 indicate a common regulation by the interferon response and suggest rather limited influence of BST2 in vivo on the disease outcome.
[A]: Is increased BST2 expression during simian immunodeficiency virus infection a determinant of disease progression in rhesus monkeys?


[Q]: Context: To document potential mediating effects of the Activator-assisted spinal manipulative therapy (ASMT) on pain and hyperalgesia after acute intervertebral foramen (IVF) inflammation.', 'The IVF inflammation was mimicked by in vivo delivery of inflammatory soup directly into the L5 IVF in adult male Sprague-Dawley rats. Thermal hyperalgesia and mechanical allodynia were determined by the shortened latency of foot withdrawal to radiant heat and von Frey filament stimulation to the hind paw, respectively. Intracellular recordings were obtained in vitro from L5 dorsal root ganglion (DRG) somata. DRG inflammation was examined by observation of the appearance and hematoxylin and eosin staining. ASMT was applied to the spinous process of L4, L5, and L6. A series of 10 adjustments were initiated 24 hours after surgery and subsequently applied daily for 7 consecutive days and every other day during the second week.', '(1) ASMT applied on L5, L6, or L5 and L6 spinous process significantly reduced the severity and duration of thermal and mechanical hyperalgesia produced by the IVF inflammation. However, ASMT applied on L4 did not affect the response in rats with IVF inflammation or the controls; (2) electrophysiological studies showed that hyperexcitability of the DRG neurons produced by IVF inflammation was significantly reduced by ASMT; (3) pathological studies showed that manifestations of the DRG inflammation, such as the increased vascularization and satellitosis, were significantly reduced 2 to 3 weeks after ASMT.
Answer: These studies show that ASMT can significantly reduce the severity and shorten the duration of pain and hyperalgesia caused by lumbar IVF inflammation. This effect may result from ASMT-induced faster elimination of the inflammation and recovery of excitability of the inflamed DRG neurons by improving blood and nutrition supplement to the DRG within the affected IVF. Manipulation of a specific spinal segment may play an important role in optimizing recovery from lesions involving IVF inflammation.
