DPP-4 inhibitor induces FGF21 expression via sirtuin 1 signaling and improves myocardial energy metabolism.

Dipeptidyl peptidase-4 (DPP-4) inhibitors are widely used incretin-based therapy for the treatment of type 2 diabetes. We investigated the cardioprotective effect of a DPP-4 inhibitor, vildagliptin (vilda), on myocardial metabolism and cardiac performance under pressure overload. Mice were treated with either vehicle or vilda, followed by transverse aortic constriction (TAC).

Isatuximab monotherapy in relapsed/refractory multiple myeloma: A Japanese, multicenter, phase 1/2, safety and efficacy study.

Isatuximab, an anti-CD38 monoclonal antibody, targets cells that strongly express CD38 including malignant plasma cells. This open-label, single-arm, multicenter, phase 1/2 trial investigated the tolerability/safety and efficacy of isatuximab monotherapy in Japanese patients with heavily pretreated, relapsed/refractory multiple myeloma (RRMM). In Phase 1, patients were sequentially assigned to receive isatuximab once weekly (QW) in cycle 1 (4 weeks) and every 2 weeks (Q2W) in subsequent cycles.

Polyglutamine-containing microglia leads to disturbed differentiation and neurite retraction of neuron-like cells.

Expanded polyglutamine-containing proteins in neurons intrinsically contributes to neuronal dysfunctions and neuronal cell death in polyglutamine (polyQ) diseases. In addition, an expanded polyQ-containing protein in microglia also leads to apoptosis of neurons. However, detailed morphological analysis of neurons exposed to conditioned medium (CM) derived from polyQ-containing microglia has not been essentially carried out.

Comparing the measurement properties and relationship to gait speed recovery of the Mini-Balance Evaluation Systems Test and the Berg Balance Scale in ambulatory individuals with subacute stroke.

Objectives: Although the Mini-Balance Evaluation Systems Test (Mini-BESTest) is known to be a reliable and valid measure of balance in individuals with stroke, the utility of this tool in relation to subacute stroke walking speed and the recovery of gait ability has not been explored. Here, we compared the measurement properties and their relationship to gait speed on the Mini-BESTest and the Berg Balance Scale (BBS) in middle and older ambulatory individuals with subacute stroke, and we investigated which balance assessment tool is more likely to capture the status of the recovery of gait speed.

Methods: We retrospectively analyzed the cases of 88 individuals 50 years or older with stroke who had been evaluated using the Mini-BESTest by using the BBS and by assessing their comfortable walking speed (CWS).

Increased Neurofilament Light Chain and YKL-40 CSF Levels in One Japanese IBMPFD Patient With VCP R155C Mutation: A Clinical Case Report With CSF Biomarker Analyses.

Inclusion body myopathy (IBM) with Paget's disease of bone (PDB) and frontotemporal dementia (IBMPFD) presents with multiple symptoms and an unknown etiology. Valosin-containing protein () has been identified as the main causative gene of IBMPFD. However, no studies on neurofilament light chain (NFL) as a cerebrospinal fluid (CSF) marker of axonal neurodegeneration or on YKL-40 as a CSF marker of glial neuroinflammation have been conducted in IBMPFD patients with mutations.

Sections of the Brief-Balance Evaluation Systems Test Relevant for Discriminating Fast Versus Slow Walking Speeds in Community-Dwelling Older Women.

Background And Purpose: Walking speed can be used to identify characteristics of frailty in older adults. It has a strong positive correlation with balance abilities. The Brief-Balance Evaluation Systems Test (Brief-BESTest) was developed to assess functions of the 6 balance control systems in a short time.

Phosphomolybdic Acid Prevents Nonspecific Nuclear Staining by Picrosirius Red but Is Converted to Molybdenum Blue by Blue Light.

Picrosirius red (PSR) staining is generally used to evaluate liver fibrosis; however, PSR sometimes causes nonspecific nuclear staining. In this study, we evaluated the ability of phosphomolybdic acid (PMA) pretreatment to prevent nonspecific nuclear staining by PSR. In a manual evaluation of 27 non-tumor samples from patients with hepatocellular carcinoma, nonspecific nuclear staining was observed in 3.

Molecular characterization of a carbon dioxide-dependent Escherichia coli small-colony variant isolated from blood cultures.

A carbon dioxide-dependent small-colony variant of Escherichia coli SH4888 was isolated from blood cultures of a patient with cholangitis. To date, little is known regarding the molecular mechanisms leading to formation of carbon dioxide-dependent phenotypes in clinical isolates, but abnormalities in the carbonic anhydrase are thought to cause carbon dioxide autotrophy. In this study DNA sequence analysis of the carbonic anhydrase-encoding can locus in the carbon dioxide-dependent E.

Prognostic nutritional index as a predictor of mortality in nontuberculous mycobacterial lung disease.

Background: Although the association between nontuberculous mycobacterial lung disease (NTM-LD) and malnutrition is known, there are a few reports on the association between the nutritional score and death in patients with NTM-LD. This study investigated the association between the nutrition data at the time of NTM-LD diagnosis and death.

Methods: A retrospective study was conducted for patients with NTM-LD who visited the Maebashi Red Cross Hospital from January 2014 to December 2018.

Isolation of thymidine-dependent and extended-spectrum-β-lactamase-producing Escherichia coli small-colony variant from urine of a septuagenarian female patient with recurrent cystitis: A case report with genetic investigation.

Thymidine-dependent small-colony variant (TD-SCV) of Escherichia coli was isolated from urine of a septuagenarian female patient on hemodialysis suffering from recurrent cystitis. The patient had been treated with frequent administrations of trimethoprim sulfamethoxazole (SXT), every time her cystitis symptoms developed. In the TD-SCV isolate, the deletion was detected in the thyA gene associated with thymidylate synthase.

SIRPα on CD11c cells induces Th17 cell differentiation and subsequent inflammation in the CNS in experimental autoimmune encephalomyelitis.

Signal regulatory protein α (SIRPα) is expressed predominantly on type 2 conventional dendritic cells (cDC2s) and macrophages. We previously showed that mice systemically lacking SIRPα were resistant to experimental autoimmune encephalomyelitis (EAE). Here, we showed that deletion of SIRPα in CD11c cells of mice (Sirpa mice) also markedly ameliorated the development of EAE.

Body mass index and mortality among middle-aged Japanese individuals with diagnosed diabetes: The Japan Public Health Center-based prospective study (JPHC study).

Aim: To examine the association between body mass index (BMI) and mortality among middle-aged people with diabetes in Japan.

Methods: A total of 3032 men and 1615 women, aged 40-69 years, with diabetes were analyzed. Cox proportional hazards models, adjusted for potential confounding factors, were used to estimate mortality hazard ratios (HRs) across BMI categories at the baseline.

These are the results of phase II study of bortezomib-melphalan-prednisolone (VMP) induction therapy followed by lenalidomide-dexamethasone (Rd) consolidation and lenalidomide maintenance in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), overall response rates (ORRs), and safety.

Comparison of effects of joint flexibility on the lumbo-pelvic rhythm in healthy university students while bending the trunk forward.

[Purpose] To clarify the influence of flexibilities of the hip and lumbar spine joints on bending the trunk forward. [Participants and Methods] We assessed the joint flexibility of 47 healthy university students using the Beighton hypermobility score and assigned them to the group of normal or poor flexibility. We performed electromyography to acquire kinematic data and analyzed the three-dimensional motion while the students bent their trunks forward.

Importance of methodology in the evaluation of renal mononuclear phagocytes and analysis of a model of experimental nephritis with Shp1 conditional knockout mice.

Tissue resident mononuclear phagocytes (Mophs), comprising monocytes, macrophages, and dendritic cells (DCs), play important roles under physiological and pathological conditions. The presence of these cells in the kidney has been known for decades, and studies of renal Mophs (rMophs) are currently underway. Since no unified procedure has been identified to isolate rMophs, results of flow cytometric analysis of rMophs have been inconsistent among studies.

Section of the Balance Evaluation Systems Test (BESTest) Cutoff Values for Walking Speed Level in Older Women With Hip Fracture.

Background And Purpose: Hip fracture is a common injury in older adults, with a high proportion of hip fractures affecting women. After a hip fracture, the recovery of the patient's walking speed is very important; one of the key determinants of walking speed is balance. The Balance Evaluation Systems Test (BESTest), a clinical balance measure, categorizes balance into 6 postural control systems.

Oxytocin receptor antagonist reverses the blunting effect of pair bonding on fear learning in monogamous prairie voles.

Social relationships among spouses, family members, and friends are known to affect physical and mental health. In particular, long-lasting bonds between socio-sexual partners have profound effects on cognitive, social, emotional, and physical well-being. We have previously reported that pair bonding in monogamous prairie voles (Microtus ochrogaster) is prevented by a single prolonged stress (SPS) paradigm, which causes behavioral and endocrine symptoms resembling post-traumatic stress disorder (PTSD) patients in rats (Arai et al.

Abdominal muscle strength and the recovery of upper extremity function in stroke patients: a study using propensity score matching.

Purpose: The purpose of this study was to understand the relationship between abdominal muscle strength and recovery of upper limb function, after adjusting for various confounding factors, such as age, gender, and sensory function.

Methods: We retrospectively analyzed data of 78 sub-acute stroke patients with mild-to-moderate upper limb dysfunction. Participants were divided into two groups, strong and weak, according to the abdominal muscle strength.

Expression of Th1/Th2 cell-related chemokine receptors on CD4 lymphocytes under physiological conditions.

Introduction: Chemokine receptors (CRs) and the prostaglandin D receptor, CRTH2, have been used as surrogate markers for cytoplasmic Th1 and Th2 cytokines. The presence of regulatory T (Treg) and Th17 cells may affect the analysis of such surrogate markers, as they share several CRs with Th1 and Th2 cells. This study aimed to determine the optimal surrogate markers of Th1 and Th2 cells under physiological conditions.

The Role and Function of microRNA in the Pathogenesis of Multiple Myeloma.

Recently, attention has been drawn to the role of non-coding regions of the genome in cancer pathogenesis. MicroRNAs (miRNAs) are small non-coding RNAs with 19-25 bases of length that control gene expression by destroying messenger RNA or inhibiting its translation. In multiple myeloma (MM), the expression of several miRNAs, such as miR-15a and miR-16, is markedly decreased and their target genes upregulated, suggesting their role as tumor-suppressing miRNAs.

Factors affecting the performance of activities of daily living in patients with advanced cancer undergoing inpatient rehabilitation: results from a retrospective observational study.

[Purpose] Many clinicians believe that rehabilitation for patients with advanced cancer is futile. We determined factors affecting the performance of activities of daily living in patients with advanced cancer based on age, gender, marital status, living arrangement, rehabilitation intensity, type of cancer, impairment, metastasis, and active cancer treatment. [Participants and Methods] We assessed the Barthel Index to evaluate the performance of activities of daily living.
