The most widely used chemotherapeutic combinations in locally advanced (LA) or metastatic pancreatic ductal adenocarcinoma(PDAC)areNab-Paclitaxel-Gemcitabine(Nab-PCT-GEM)andFluorouracil,Folinicacid,Oxaliplatin, and irinotecan (FOLFIRINOX). Chemo-resistance, typical of PDAC, appears to be due to the negative influence of stroma population cells, namely regulatory T cells (Treg) and myeloid-derived suppressor cells, macrophages with inhibitory effects on the antitumor activity of the innate and adaptive immune systems, and resistance to cancer treatment. Among other factors that may influence immune surveillance, constant physical activity appears to reduce the risk of cancer-related mortality and cardiovascular risk. However, this does not seem to increase the survival of patients with PDAC. The exception is our young inoperable patient. For LA head PDAC, he was treated with seven cycles of Nab-PCT-GEM and RT 50 Gy/15 fractions combined to biweekly GEM and salvage FOLFIRINOX. The five-year surviving patient travelled 15,000 km on foot and continues inexorably his "walking therapy".

Mycotoxigenic fungi and mycotoxins in 3 inbred lines (hybrids resistant to corn ear rot) were identified in twenty samples. The maize (Zea mays) accessions were collected in five plots of two municipalities in High Valley, state of Hidalgo. The fungal population was determined with a microbiological dilution method used two culture media (PDA and ELA), for the detection of mycotoxins with thin layer chromatography with visual inspection in UV light and a direct competitive enzyme-linked immunosorbent (ELISA). The results showed high moisture content in all hybrids evaluated on an average of 38.3% and a 1.8 × 103 UFC/g fungus, values within the permitted limits by the Mexican legislation;however the most prevalent fungi were Fusarium sp. (76%), Alternaria sp. (14%), penicillium sp. (4%) and Aspergillus sp. (5%), and the species Aspergillus nidulas, Aspergillus flavus, Fusarium verticillioides, Fusarium poae, and penicillium ochraceum. The aflatoxin concentration was observed in a range from 2 to 13 ng/g and 370 to 660 ng/g to fumonisins. It is concluded that trilinear corn hybrids have a variety of pathogenic potential fungi. The two genetic hybrids showed levels of aflatoxins and fumonisin safe for human consumption, contrary to one hybrid, with a content not suitable for human consumption. A better understanding of genetic hybrids corn will improve predictive mycotoxin contamination.

The concept of single health is currently undoubtedly one of the most relevant in pandemic times, where humans and animals are together in the same world. penicillin was discovered in the last century by Alexander Fleming, used against infectious agents mainly of bacterial types, such as Staphylococcus aureus, Corynebacterium, Streptococcus, Brucella and Mycobacterium are examples of cattle pathogens. The bacteria have developed defense mechanisms allowing them to survive in the host cell (mutation) even in the presence of antimicrobials (bacterial selection). The aim of the study was to examine the degree of knowledge of antibiotics through a structured survey of ten questions, addressed to eighty-six students from the Bachelor of Veterinary Medicine and Zootechnics in 2019. Based on the information collected and after analyzing their answers, 63.14% of the students work in Clinics and Universities, 89.47% recognize the need for a quantified prescription, 47.36% mentioned that the Veterinary Medicine can prescribe antimicrobials, 52.63% support the use of antimicrobials for all microorganisms including viruses, 52.63% use the labeling to consult the withdrawal time and 100% identify that it is the withdrawal time and the practices that lead to the development of antimicrobial resistance. It is concluded that most of the students identify malpractice as the trigger for bacterial resistance, however their knowledge is not adequate to avoid antibiotic resistance to humans. It is recommended to reinforce the courses of microbiology, pharmacology and virology in the Veterinary Medicine and Zootechnics degree, as well as to be updated on alternatives such as the use of phytobiotics.

Anaemia and thrombocytopenia are haematological disorders that can be detected in many human immunodeficiency virus(HIV)-positive patients during the development of HIV infection. The progressive decline of erythrocytes and platelets plays an important role both in HIV disease progression and in the clinical and therapeutic management of HIV-positive patients. HIV-dependent impairment of the megakaryocyte and erythrocyte lineages is multifactorial and particularly affects survival, proliferation and differentiation of bone marrow(BM) CD34+ haematopoietic progenitor cells, the activity of BM stromal cells and the regulation of cytokine networks. In this review, we analyse the ma-jor HIV-related mechanisms that are involved in the genesis and development of the anaemia and thrombocytopenia observed in HIV positive patients.

This contribution presents a magnetron sputter deposition tool with broadband optical monitor and online re-optimization capability for high volume production. The layer termination relies on a comparison of the actually measured reflection spectrum with a pre-calculated target spectrum. Spectra recorded after each deposited layer are analyzed by the re-optimization module and in case of significant deviations layer thicknesses and target spectra for the remaining layers are recalculated. This technique significantly improves the performance and reproducibility in case of highly denlanding coating designs and is able to correct abnormal production errors in individual layers, which will lead to coating failure without re- optimization.
