Factors Associated With the Absence of Cervical Spine Instability in Rheumatoid Arthritis: A >10-Year Prospective Multicenter Cohort Study.

Objective: To identify factors associated with the absence of cervical spine instability in patients with rheumatoid arthritis (RA).

Methods: Cervical spine instability was defined as the presence of at least one of the following: atlantoaxial subluxation, vertical subluxation of the axis, or subaxial subluxation. In 2001-2002, 634 enrolled outpatients with "classical" or "definite" RA underwent a radiographic cervical spine checkup.

Evaluation of Pelvic Pathology of Subfertile Women by Transvaginal Sonography and Correlation with Laparoscopic Findings.

Damage of fallopian tube, endometriosis, fibroid uterus, adenomysis and polycystic ovary syndrome are the major pelvic pathology that causes subfertility. Although there are many diagnostic tests available, the clinical presentation of each patient can usually be linked to specific and efficient testing strategies. Transvaginal sonographic (TVS) imaging is an effective, easy to use, safe and readily available noninvasive means to evaluate fertility potential.

Second home blood pressure measurements per occasion predict incident cardiovascular events in type 2 diabetes: KAMOGAWA-HBP study.

Home blood pressure (HBP) monitoring is a better prognostic predictor than clinical BP monitoring. However, the suggested number of HBP measurements in each occasion varies across guidelines. The study aimed to identify which HBP measurements in each occasion are more closely associated with new cardiovascular events in patients with type 2 diabetes.

A Comprehensive Evaluation of Iris Segmentation on Benchmarking Datasets.

Iris is one of the most widely used biometric modalities because of its uniqueness, high matching performance, and inherently secure nature. Iris segmentation is an essential preliminary step for iris-based biometric authentication. The authentication accuracy is directly connected with the iris segmentation accuracy.

A case of mitral regurgitation due to bilateral undifferentiated papillary muscles with detailed preoperative diagnosis of associated morphological abnormalities.

Incomplete differentiation of the mitral valve structures during fetal life results in the papillary muscles and tendon cords becoming hypoplastic, a condition termed undifferentiated papillary muscles (UDPM). This fetal abnormality causes a group of diseases that cause mitral valve dysfunction in adult life. Here, we report a case of UDPM centered on the medial posterior apex in which detailed morphological abnormalities were diagnosed preoperatively using echocardiography and three-dimensional computed tomography (3DCT) analysis, contributing to plastic surgery.

Expression of soluble guanylate cyclase (sGC) and its ability to form a functional heterodimer are crucial for reviving the NO-sGC signaling in PAH.

In order to determine the underpinnings of a dysfunctional NO-sGC signal pathway which occurs in pulmonary arterial hypertension (PAH), we investigated pulmonary arterial smooth muscle cells (PASMCs) derived from PAH patients. We found low expression of sGC, a poor sGCα1β1 heterodimer and this correlated with low expression of its facilitator chaperon, hsp90. Treating PASMCs overnight (16 h) with low micromolar doses of a slow release NO donor DETANONOate, reinstated the sGCα1β1 heterodimer and restored its NO-heme dependent activity.

Acquired Amegakaryocytic Thrombocytopenia with Glycoprotein IIb/IIIa Antibody in a Patient with Mantle Cell Lymphoma.

Background Acquired amegakaryocytic thrombocytopenia (AAMT) is a rare disorder characterized by thrombocytopenia, marked megakaryocytic hypoplasia, and preserved other-lineage hematopoiesis in the bone marrow. The etiology of AAMT remains poorly understood owing to its rarity. Case description We encountered a diagnostically challenging case involving a 66-year-old man who showed severe thrombocytopenic bleeding with isolated megakaryocytic hypoplasia, elevated serum thrombopoietin levels, glycoprotein IIb/IIIa antibody positivity, and prolonged platelet transfusion refractoriness following mantle cell lymphoma (MCL).

Intramuscular condition of swallowing-related muscles using shear-wave elastography: A preliminary study in healthy adults.

Background: Assessing the internal condition of swallowing-related muscles and muscle strength and size is important because their deterioration may lead to dysphagia. However, there are few reports on stiffness of swallowing-related muscles measured using shear-wave elastography (SWE) and their qualitative characteristics.

Objectives: We measured stiffness of swallowing-related muscles using SWE to investigate the relationship between muscle stiffness and body composition as well as other relevant variables in healthy adults.

An investigation of the pigments, antioxidants and free radical scavenging potential of twenty medicinal weeds found in the southern part of Bangladesh.

Despite their overlooked status, weeds are increasingly recognized for their therapeutic value, aligning with historical reliance on plants for medicine and nutrition. This study investigates the medicinal potential of native weed species in Bangladesh, specifically pigments, antioxidants, and free radical scavenging abilities. Twenty different medicinal weed species were collected from the vicinity of Khulna Agricultural University and processed in the Crop Botany Department Laboratory.

Comparative analysis of nutrient composition and antioxidant activity in three dragon fruit cultivars.

Dragon fruit has significant economic value in many countries due to has excellent nutritional content, health advantages, and adaptability to different climates, making it an important crop in the global fruit industry. This study aimed to gather comprehensive nutritional data on three dragon fruit cultivars by analysing the levels of micronutrients, fibre, carbohydrates, antioxidants, vitamins, and minerals in their pulps. Uniform dragon fruit samples underwent thorough analysis for proximate composition, mineral content, pigments, antioxidants, and vitamin C, with statistical methods used to assess significant differences among the parameters studied.

The CB1 negative allosteric modulator PSNCBAM-1 reduces ethanol self-administration via a nonspecific hypophagic effect.

Alcohol use disorder (AUD) affects >15 million people in the United States. Current pharmacotherapeutic treatments for AUD are only modestly effective, necessitating the identification of new targets for medications development. The cannabinoid receptor type 1 (CB1) has been a target of interest for the development of medications for substance use disorders and other compulsive disorders.

Regional variations in allergen-induced airway inflammation correspond to changes in soluble guanylyl cyclase heme and expression of heme oxygenase-1.

Asthma is characterized by airway remodeling and hyperreactivity. Our earlier studies determined that the nitric oxide (NO)-soluble guanylyl cyclase (sGC)-cGMP pathway plays a significant role in human lung bronchodilation. However, this bronchodilation is dysfunctional in asthma due to high NO levels, which cause sGC to become heme-free and desensitized to its natural activator, NO.

Successful Treatment of Epstein-Barr Virus Reactivation-associated Transverse Myelitis Following Herpes Zoster with Intravenous Rituximab in a Cord Blood Transplant Recipient.

The Epstein-Barr virus (EBV) is associated with many malignancies and autoimmune diseases, including multiple sclerosis. In addition, EBV rarely but occasionally causes central nervous system (CNS) complications. We herein report a case of transverse myelitis (TM) associated with systemic EBV reactivation after herpes zoster infection in a cord blood transplant recipient.

Association of Elevated Serum Branched-chain Amino Acid Levels With Longitudinal Skeletal Muscle Loss.

Context: Branched-chain amino acids (BCAA) are substrates for protein synthesis. Although their intake may contribute to an increase in skeletal muscle mass, elevated serum BCAA levels have been reported to be associated with insulin resistance, potentially resulting in decreased skeletal muscle mass.

Objective: This study aimed to explore the association between elevated serum BCAA levels and longitudinal skeletal muscle loss.

Regions of Inflammation in mouse asthma correspond to regions of heme-free soluble guanylyl cyclase and can be tracked by marked expression of heme-oxygenase-1.

Asthma is characterized by airway remodeling and hyperreactivity. Our earlier studies determined that the Nitric Oxide (NO)-soluble Guanylyl Cyclase (sGC)-cGMP pathway plays a significant role in human lung bronchodilation. However this bronchodilation is dysfunctional in asthma due to high NO levels which cause sGC to become heme-free and desensitized to its natural activator, NO.
