Another way? An investigation into an institution's use of the Wayson stain in re-evaluating "no organisms seen" on Gram stain smears from positive blood cultures.

Automated continuous monitoring blood culture instruments identify metabolism byproducts and flag blood culture bottles as "positive." A Gram stain is used to visualize and characterize the microbial growth in the broth and initiate additional testing. When no organisms are seen (NOS) on Gram stain, in our laboratory, bottles are reevaluated with a Wayson stain, a rapid one-step stain that provides contrast between organisms and the background, especially in Gram-negative organisms.

Deduced Conservation Strategy of the Macaques in China from their Evolutionary Development.

Understanding how climate, ecological and environmental changes, and anthropogenic activities have driven animals' development and predicting their prospective distribution profiles are essential to making a tangible conservation strategy. Macaques () distributed in China provide an ideal research model for such an effort. We reconstruct their geographic distribution profiles from the last inter-glaciation (LIG, 120,000-140,000 years BP), the Last Glacial Maximum (LGM, 22,000 years BP), and the present (1970-2000), based on which we deduce their distribution perspective in the 2050s.

Origin, Distribution, and Influential Factors of Organic Acids in Deep and Ultradeep Clastic Reservoirs within the Fukang Sag of the Junggar Basin.

In deep and ultradeep clastic reservoirs, secondary porosity functions as the primary space for hydrocarbon storage, intricately associated with the dissolution processes of water-soluble organic acids (WSOAs). However, conventional theories concerning secondary porosity predominantly emphasize medium-depth or shallow reservoirs, lacking a thorough investigation into how WSOA-driven mechanisms affect deeper strata formations. To bridge this gap, our research involved selecting 36 samples from Mesozoic Permian clastic rock formations situated in western China's Fukang Sag within the Junggar Basin region.

Mutant huntingtin protein decreases with CAG repeat expansion: implications for therapeutics and bioassays.

Huntington's disease is an inherited neurodegenerative disorder caused by a CAG repeat expansion that encodes a polyglutamine tract in the huntingtin (HTT) protein. The mutant CAG repeat is unstable and expands in specific brain cells and peripheral tissues throughout life. Genes involved in the DNA mismatch repair pathways, known to act on expansion, have been identified as genetic modifiers; therefore, it is the rate of somatic CAG repeat expansion that drives the age of onset and rate of disease progression.
