Temperature effects on nitrogen removal and NO emissions in anammox reactors.

Mainstream anammox faces challenges in adapting to non-optimal temperatures and managing greenhouse gas emissions. This study investigates nitrogen removal and NO emissions in attached-growth anammox reactors subjected to rapid temperature shifts (15 - 55 °C). Temperature reductions to 15 - 25 °C had minimal impact on the anammox bacterial populations, with nitrogen removal rates of 0.

Process performance of in-situ bio-methanation for co-digestion of sewage sludge and lactic acid, aiming to utilize waste poly-lactic acid as methane.

This study examined hydrogen conversion efficiency and operational stability in pilot-scale in-situ bio-methanation during the co-digestion of sewage sludge and lactic acid (partially derived from waste poly-lactic acid). Parallel laboratory-scale experiments were also conducted. In the pilot, hydrogen conversion efficiency decreased from 98.

Succinic semialdehyde derived from the gut microbiota can promote the proliferation of adult T-cell leukemia/lymphoma cells.

Adult T-cell leukemia/lymphoma (ATLL) is a refractory blood cancer with severe immunodeficiency resulting from retroviral infection. ATLL develops in only 5 % of HTLV-1-infected individuals, but the entire mechanism of ATLL progression remains unknown. Since recent studies have reported that the gut microbiome influences the progression of various diseases, we hypothesized that ATLL is also related to the gut microbiome and aimed to investigate this relationship.

Efficacy and Validity of Percutaneous Transhepatic Gallbladder Drainage as a Bridge to Surgery for Octogenarian and Older Patients With Acute Cholecystitis: A Single-Center Retrospective Observational Study in Japan.

Background: Japan currently has a super-aged society, with a rapid increase in elderly patients in need of medical care. Determining treatment strategies for acute cholecystitis (AC) in very elderly patients with various comorbidities is often difficult. Although percutaneous cholecystostomy (PC) is a less-invasive treatment option, its impact on subsequent surgery remains debatable.

Antiviral immune response against HTLV-1 invalidates T-SPOT.TB results in patients with HTLV-1-positive rheumatic diseases.

Background: T-SPOT.TB, one of the screening tests for latent tuberculosis infection (LTBI), yields invalid results in human T-cell leukemia virus type 1 (HTLV-1)-positive patients with rheumatoid arthritis. However, the detailed mechanisms behind this invalidation are unclear.
