Liver biopsy as a useful diagnostic tool for hepatic sarcoidosis: A case report.

In certain cases, it is difficult to distinguish hepatic sarcoidosis from malignant lymphoma or drug-induced liver injury and to select the proper treatment for this condition. The present study describes the case of a female patient in her 30s who was referred to the hospital due to fever, arthralgia, myalgia and abnormal liver function test results for 4 months. A laboratory examination revealed elevated levels of serum angiotensin-converting enzyme (ACE) and soluble interleukin-2 receptor (sIL-2R), as well as an increase in serum hepatic and biliary tract enzymes.

Elderly patient with unresectable advanced‑stage hepatocellular carcinoma who received atezolizumab plus bevacizumab and achieved a complete response: A case report.

Hepatocellular carcinoma (HCC) is a common malignancy with a poor prognosis, particularly in patients with advanced-stage disease, elderly individuals and/or in those with poor liver function. Immune checkpoint inhibitor-containing therapies, such as atezolizumab, an anti-programmed death ligand-1 monoclonal antibody, plus bevacizumab, an anti-vascular endothelial growth factor monoclonal antibody, may be effective and safe therapeutic options for elderly patients with advanced-stage HCC. The present study reports the case of a male patient his 80s who consumed alcohol with unresectable advanced-stage HCC who received combination therapy comprising atezolizumab plus bevacizumab for 6 months.

Site-specific glycosylation and single amino acid substitution dramatically reduced the immunogenicity of β-lactoglobulin.

To reduce the immunogenicity of β-lactoglobulin (BLG), we prepared recombinant BLG which has both site-specific glycosylation and single amino acid substitution (D28N/P126A), and expressed it in the methylotrophic yeast Pichia pastoris by fusion of the cDNA to the sequence coding for the α-factor signal peptide from Saccharomyces cerevisiae. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis indicated that the D28N/P126A was conjugated with a ∼4 kDa high-mannose chain. D28N/P126A retained ∼61% of the retinol-binding activity of BLG.

Reduced immunogenicity of β-lactoglobulin by single amino acid substitution.

To reduce the immunogenicity of β-lactoglobulin (BLG), we prepared single amino acid substituted recombinant BLG mutants (BLG/P126A, BLG/V128D and BLG/D129A) in the methylotrophic yeast by fusion of the cDNA to the sequence coding for the α-factor signal peptide from . Isoelectric points of single amino acid substituted BLGs were lower than that of native BLG. CD spectra indicated that the secondary structure of BLG had maintained native structure in single amino acid substituted BLGs.

A pediatric case of Stevens-Johnson syndrome with acute liver failure, resulting in liver transplantation.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are fatal adverse skin reactions characterized by high fever, epidermal detachment, and mucositis. It is well known that SJS/TEN occasionally affects various organs, leading to permanent damage and death in some patients. Although acute liver dysfunction is a relatively common complication of SJS/TEN, severe acute liver dysfunction requiring liver transplantation is rare.

Japanese Man with HCV Genotype 4 Infection and Cirrhosis Who Was Successfully Treated by the Combination of Glecaprevir and Pibrentasvir.

A 74-year-old man with a history of transfusion at 35 years old in Egypt was referred to our hospital. He was infected with hepatitis C virus (HCV) genotype 4 (GT4), which is a rare HCV GT in Japan, and was also diagnosed with hepatic compensated cirrhosis. We safely treated the patient for 12 weeks with the combination of glecaprevir and pibrentasvir, and a sustained virologic response (SVR) was achieved.

Mortality and risk factors on admission in toxic epidermal necrolysis: A cohort study of 59 patients.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening disorders characterized by widespread epidermal necrosis of the skin and mucosa. The severity-of-illness scoring system for TEN (SCORTEN) was widely used since 2000 as a standard prognostic tool consisting of seven clinical values.

Methods: To evaluate the prognosis using current treatments and risk factors for mortality, we retrospectively analyzed 59 cases of TEN, including SJS/TEN overlap treated in two university hospitals from January 2000 to March 2020.

Relationships between body composition and pulmonary function in a community-dwelling population in Japan.

Pulmonary diseases, including chronic obstructive pulmonary disease (COPD), are major chronic diseases that result in decreased pulmonary function. Relationships between body composition and pulmonary function have been reported. However, few epidemiological studies have used the visceral fat area (VFA) to measure body composition.

A chemical genomics-aggrephagy integrated method studying functional analysis of autophagy inducers.

Macroautophagy/autophagy plays a critical role in the pathogenesis of various human diseases including neurodegenerative disorders such as Parkinson disease (PD) and Huntington disease (HD). Chemical autophagy inducers are expected to serve as disease-modifying agents by eliminating cytotoxic/damaged proteins. Although many autophagy inducers have been identified, their precise molecular mechanisms are not fully understood because of the complicated crosstalk among signaling pathways.

Case of severe bullous erythema including intertrigo-like eruptions with angioedema induced by pegylated liposomal doxorubicin.

Pegylated liposomal doxorubicin (PLD) is an anthracycline anticancer agent used in ovarian cancer and a form of doxorubicin enclosed in pegylated liposomes. There are only a few reports on intertrigo-like eruptions caused by PLD. We describe the first case of severe bullous erythema, including intertrigo-like eruptions with angioedema, induced by PLD in Japan.

Towards Objective Olfactory Evaluation Based On Peripheral Arterial Stiffness And Heart Rate Variability Indices.

This paper proposes an olfactory stimulation-biological response measurement system aiming for quantitative and objective evaluation the odor quality. The system calculates arterial stiffness index $\beta $ proposed by our group, the low frequency/high frequency (LF/HF), and heart rate (HR) during presenting odor stimuli. An experiment of olfactory sensory assessment using the proposed system is conducted.

A FRET biosensor for necroptosis uncovers two different modes of the release of DAMPs.

Necroptosis is a regulated form of necrosis that depends on receptor-interacting protein kinase (RIPK)3 and mixed lineage kinase domain-like (MLKL). While danger-associated molecular pattern (DAMP)s are involved in various pathological conditions and released from dead cells, the underlying mechanisms are not fully understood. Here we develop a fluorescence resonance energy transfer (FRET) biosensor, termed SMART (a sensor for MLKL activation by RIPK3 based on FRET).

Anserine/Carnosine Supplementation Preserves Blood Flow in the Prefrontal Brain of Elderly People Carrying APOE e4.

In a previously reported double-blind, randomized controlled trial (RCT), we demonstrated that daily supplementation with anserine (750 mg) and carnosine (250 mg) improves brain blood flow and memory function in elderly people. Here, we conducted a sub-analysis of MRI data and test scores from the same RCT to determine whether anserine/carnosine supplementation specifically benefits elderly people carrying the APOE e4 allele, which is a risk gene for accelerated brain aging and for the onset of Alzheimer's Disease. We collected data from 68 participants aged 65 years or older who received anserine/carnosine supplementation (ACS) or placebo for 12 months.

Immunomodulation by food: impact on gut immunity and immune cell function.

Recent studies have revealed that various food components affect the immune response. These components act on various immune cells, and their effects are mediated through the intestinal immune system and, in some cases, the intestinal microbiota. In this review, we describe the immunomodulating effects of various food components, including probiotics, prebiotics, polysaccharides, vitamins, minerals, fatty acids, peptides, amino acids and polyphenols.

Anserine/Carnosine Supplementation Suppresses the Expression of the Inflammatory Chemokine CCL24 in Peripheral Blood Mononuclear Cells from Elderly People.

Our goal was to determine whether anserine/carnosine supplementation (ACS) suppresses chemokine levels in elderly people. In a double-blind randomized controlled trial, volunteers were assigned to the ACS or placebo group (1:1). Sixty healthy elderly volunteers (active, = 30; placebo, = 30) completed the study.

RNA and a cell wall component of Enterococcus faecalis IC-1 are required for phagocytosis and interleukin 12 production by the mouse macrophage cell line J774.1.

Enterococcus faecalis is a resident lactic acid bacterium in the human intestine. Its immunostimulatory action was reported to be enhanced by heat sterilization. To investigate its beneficial actions, we evaluated the ability of 10 E.

Catechol Groups Enable Reactive Oxygen Species Scavenging-Mediated Suppression of PKD-NFkappaB-IL-8 Signaling Pathway by Chlorogenic and Caffeic Acids in Human Intestinal Cells.

Chlorogenic acid (CHA) and caffeic acid (CA) are phenolic compounds found in coffee, which inhibit oxidative stress-induced interleukin (IL)-8 production in intestinal epithelial cells, thereby suppressing serious cellular injury and inflammatory intestinal diseases. Therefore, we investigated the anti-inflammatory mechanism of CHA and CA, both of which inhibited hydrogen peroxide (H₂O₂)-induced transcriptional activity. They also significantly suppressed nuclear factor kappa-light-chain-enhancer of activated B cells () transcriptional activity, nuclear translocation of the p65 subunit, and phosphorylation of IκB kinase (IKK).

Enhancement of Oral Tolerance Induction in DO11.10 Mice by Lactobacillus gasseri OLL2809 via Increase of Effector Regulatory T Cells.

Food allergy is a serious problem for infants and young children. Induction of antigen-specific oral tolerance is one therapeutic strategy. Enhancement of oral tolerance induction by diet is a promising strategy to prevent food allergy in infants.

Effect of Anserine/Carnosine Supplementation on Verbal Episodic Memory in Elderly People.

Our goal in this study was to determine whether or not anserine/carnosine supplementation (ACS) is capable of preserving cognitive function of elderly people. In a double-blind randomized controlled trial, volunteers were randomly assigned to an ACS or placebo group at a 1:1 ratio. The ACS group took 1.

Effects of Food-Derived Collagen Peptides on the Expression of Keratin and Keratin-Associated Protein Genes in the Mouse Skin.

Oral ingestion of collagen peptides (CP) has long been suggested to exert beneficial effects on the skin, but the molecular events induced by CP on the skin remain unclear. Here, we investigated the effects of oral CP administration on gene expression in hairless mouse skin and of prolyl-hydroxyproline (Pro-Hyp), a collagen-derived dipeptide, on gene expression in a coculture of mouse skin keratinocytes and fibroblasts. Using microarray analysis, we found that oral administration of CP to hairless mice for 6 weeks induced increased expression of Krtap and Krt genes in the skin.
