Lentilactobacillus hilgardii H-50 strongly inhibits lipopolysaccharide-induced inflammatory responses in mouse splenocytes via its specific surface layer proteins.

AIMS: Certain lactic acid bacteria (LAB) are known to have anti-inflammatory effects; however, hiochi bacteria, which are taxonomically classified as LAB and known to spoil a traditional Japanese alcoholic beverage, have not been studied in the same context. The aim of this study is to investigate the anti-inflammatory effects of hiochi bacteria strains and the underlying mechanisms. METHODS AND RESULTS: We screened 45 strains of hiochi bacteria for anti-inflammatory effects and found that Lentilactobacillus hilgardii H-50 strongly inhibits lipopolysaccharide (LPS)-induced secretion of tumor necrosis factor (TNF)-α, interleukin (IL)-1ß, and IL-6 in mouse splenocytes. This inhibition is attributed to its specific surface layer proteins (SLPs), which directly bind to LPS. CONCLUSIONS: The L. hilgardii H-50 strain exerts anti-inflammatory effects through its SLPs.

Patients' and families' opinions via suggestion boxes for improving hospital care for cancer patients: Analysis of 3419 cases over 11 years.

BACKGROUND: There has been a paradigm shift in cancer treatment from curing disease to both curing disease and caring for patients. In terms of care for patients, the opinions of patients and their families are important for improving medical services. AIM: The opinions of patients and families were collected at Shizuoka Cancer Center (SCC) and examined from the standpoint of characteristics, response status, and temporal changes. METHODS: Patients' and families' opinions submitted to suggestion boxes at SCC over an 11-year period (2005-2015) were analyzed. Opinions were categorized as complaints or compliments, with sub-categories including "facilities, goods, and medical care," "people," "time," and "other." The status of facilities' response to complaints was categorized as "responded," "did not respond", and "difficult to respond". RESULTS: Changes in the number of opinions and content over time were examined. In total, 3419 opinions were collected; 69.1% were complaints, and 30.5% were compliments. Of the complaints, 53.4% were related to "facilities, goods, and medical care" (mainly focusing on "poor product quality" and "shortage of goods"), 38.7% were related to "people," and 7.7% to "time." Of the compliments, 82.4% were about "people," all of which concerned facility staff. Facilities' responses to complaints were as follows: "responded" (42.4%), "did not respond" (14.3%), and "difficult to respond" (43.3%). CONCLUSION: Understanding patients' and families' opinions is effective for strengthening trust between patients and healthcare professionals, promoting holistic care.

Involvement of a cyclic adenosine monophosphate-dependent signal in the diet-induced canalicular trafficking of adenosine triphosphate-binding cassette transporter g5/g8.

UNLABELLED: The adenosine triphosphate-binding cassette (ABC) half-transporters Abcg5 and Abcg8 promote the secretion of neutral sterol into bile. Studies have demonstrated the diet-induced gene expression of these transporters, but the regulation of their trafficking when the nutritional status changes in the liver remains to be elucidated. Here, we generated a novel in vivo kinetic analysis that can monitor the intracellular trafficking of Abcg5/Abcg8 in living mouse liver by in vivo transfection of the genes of fluorescent protein-tagged transporters and investigated how hypernutrition affects the canalicular trafficking of these transporters. The kinetic analysis showed that lithogenic diet consumption accelerated the translocation of newly synthesized fluorescent-tagged transporters to intracellular pools in an endosomal compartment and enhanced the recruitment of these pooled gene products into the bile canalicular membrane in mouse liver. Because some ABC transporters are reported to be recruited from intracellular pools to the bile canaliculi by cyclic adenosine monophosphate (cAMP) signaling, we next evaluated the involvement of this machinery in a diet-induced event. Administration of a protein kinase A inhibitor, N-(2-{[3-(4-bromophenyl)-2-propenyl]amino}ethyl)-5-isoquinolinesulfonamide, decreased the canalicular expression of native Abcg5/Abcg8 in lithogenic diet-fed mice, and injection of a cAMP analog, dibutyryl cAMP, transiently increased their levels in standard diet-fed mice, indicating the involvement of cAMP signaling. Indeed, canalicular trafficking of the fluorescent-tagged Abcg5/Abcg8 was enhanced by dibutyryl cAMP administration. CONCLUSION: These observations suggest that diet-induced lipid loading into liver accelerates the trafficking of Abcg5/Abcg8 to the bile canalicular membrane through cAMP signaling machinery.
