The Higher Positive Amyloid Deposition in Electrophysiologically Proven Idiopathic Carpal Tunnel Syndrome Patients.

Carpal tunnel syndrome (CTS) due to amyloid deposition was reported to precede fatal cardiac amyloidosis by several years. Although nerve conduction study (NCS) supports CTS diagnosis, the incidence of positive amyloid deposition in electrophysiologically proven CTS is unclear. We retrospectively analysed the demographic data including age, gender, bilateral hand involvement, amyloid deposition and NCS results, of 111 consecutive CTS patients with postoperative symptom improvement (mean 71.

Statistics of Visceral Sarcoma in Japan: Report From the Population-Based National Cancer Registry (NCR) in Japan.

Background And Objectives: Sarcomas developing in the visceral organs are extremely rare, with no previous reports to describe their national epidemiology. We analyzed Japanese domestic statistics for visceral sarcoma, using the National Cancer Registry (NCR) in Japan, a population-based database launched in 2016.

Methods: We identified 3245 cases of visceral sarcomas in the NCR dated 2016-2019 to analyze demographic and disease information, initial diagnostic process, volume and type of the hospitals, treatment, and prognosis.

Increased nerve growth factor expression and osteoclast density are associated with subchondral bone marrow lesions in osteoarthritic knees.

Objectives: Subchondral bone marrow lesions (BMLs) detected on magnetic resonance imaging in knee osteoarthritis (OA) are associated with knee pain, though the mechanisms remain unknown. Increased nerve growth factor (NGF) expression and osteoclast density in subchondral bone appear to be the key features associated with bone pain in knee OA. Therefore, we aimed to identify associations among NGF, osteoclasts, and BMLs in knee OA.

Functional Modification of Cyanobacterial Phycobiliprotein and Phycobilisomes through Bilin Metabolism Control.

Phycobilisomes (PBSs) are light-harvesting antenna complexes in cyanobacteria that adapt to diverse light environments through the use of phycobiliproteins within the PBS structures. Freshwater cyanobacteria, such as PCC 7942, thrive under red light because of the presence of phycocyanin (PC) and its chromophore, phycocyanobilin (PCB), in the PBS. Cyanobacteria in shorter-wavelength light environments such as green light, employ phycoerythrin paired with phycoerythrobilin (PEB) along with PC in the PBS.

[Malignant Solitary Fibrous Tumor Compressing the Right Ventricle].

An 84-year-old woman was referred to our department with an abnormal mass detected on a chest computed tomography (CT) scan. The CT scan revealed a tumor between the sternum and the right ventricle, fed by the left internal thoracic artery. Multiple hepatic nodules were also observed.

[A case in which endoscopic ultrasound-guided transrectal drainage was effective for pelvic abscess].

The patient, a 33-year-old female, presented to her local doctor with lower abdominal pain. She was referred to our hospital for a plain CT scan, which revealed signs of ileitis. Because acute appendicitis could not be ruled out, the patient was hospitalized.

Plant regeneration in the new era: from molecular mechanisms to biotechnology applications.

Plants or tissues can be regenerated through various pathways. Like animal regeneration, cell totipotency and pluripotency are the molecular basis of plant regeneration. Detailed systematic studies on Arabidopsis thaliana gradually unravel the fundamental mechanisms and principles underlying plant regeneration.

Effect of nonsense-mediated mRNA decay factor SMG9 deficiency on premature aging in zebrafish.

SMG9 is an essential component of the nonsense-mediated mRNA decay (NMD) machinery, a quality control mechanism that selectively degrades aberrant transcripts. Mutations in SMG9 are associated with heart and brain malformation syndrome (HBMS). However, the molecular mechanism underlying HBMS remains unclear.

A pH imbalance is linked to autophagic dysregulation of inner ear hair cells in Atp6v1ba-deficient zebrafish.

V-ATPase is an ATP hydrolysis-driven proton pump involved in the acidification of intracellular organelles and systemic acid-base homeostasis through H secretion in the renal collecting ducts. V-ATPase dysfunction is associated with hereditary distal renal tubular acidosis (dRTA). ATP6V1B1 encodes the B1 subunit of V-ATPase that is integral to ATP hydrolysis and subsequent H transport.

Association between infrapatellar fat pad ultrasound elasticity and anterior knee pain in patients with knee osteoarthritis.

This study investigates whether infrapatellar fat pad (IPFP) elasticity is associated with anterior knee pain in patients with knee osteoarthritis (KOA). The IPFP elasticity of 97 patients with KOA (Kellgren and Lawrence [KL] grades of the femorotibial and patellofemoral joints ≥ 2 and ≤ 2, respectively), aged 46-86 years, was evaluated via shear wave speed using ultrasound elastography. The patients were divided into two groups according to the presence or absence of anterior knee pain.

Assessment of multiple domains of pain following BNT162b2 mRNA COVID-19 vaccination.

Pain at the injection site is the most frequent reaction among COVID-19 vaccine recipients, but its characteristics were not fully described yet. The purpose of this study was to investigate multiple domains of pain following BNT162b2 mRNA vaccination. We included 107 subjects undergoing primary shot of the vaccination twice into deltoid muscle with a 3-week interval.

A comparison of reoperation rates after single-level anterior cervical discectomy and fusion (ACDF) between the procedures with and without anterior plate fixation.

Introduction: The plate fixation for anterior cervical discectomy and fusion (ACDF) has become increasingly widespread for facilitating early mobilization and improving fusion rate. However, apart from multilevel operations, there is still some controversy over its use for single-level ACDF. This retrospective study has compared the reoperation rates after single-level ACDFs performed at our institution between the procedures with and without plate fixation.

Precision of the ultrasonography-integrated tibial extramedullary guide for total knee arthroplasty.

Purpose: Precise determination of the tibial mechanical axis in total knee arthroplasty (TKA) requires intraoperative identification of the talus center. We present the ultrasonography-integrated tibial extramedullary guide (USG) that enables real-time visualization of the talus. This study assesses the precision of USG compared to computer-assisted surgery (CAS) and validates the efficacy of USG.

Association Between Power Doppler Ultrasound Signals and Chronic Pain After Total Knee Arthroplasty: A Cross-Sectional Explorative Study.

Purpose: Some patients experience chronic postsurgical pain (CPSP) after total knee arthroplasty (TKA) despite the absence of clinical or radiographic abnormalities. Postoperative synovitis as a cause of CPSP after TKA has received limited research attention. This study aimed to investigate the relationship between synovitis after TKA and CPSP.

Conformational change in an engineered biliverdin-binding cyanobacteriochrome during the photoconversion process.

Cyanobacteriochromes (CBCRs) derived from cyanobacteria are linear-tetrapyrrole-binding photoreceptors related to the canonical red/far-red reversible phytochrome photoreceptors. CBCRs contain chromophore-binding cGMP-specific phosphodiesterase/adenylate cyclase/FhlA (GAF) domains that are highly diverse in their primary sequences and are categorized into many subfamilies. Among this repertoire, the biliverdin (BV)-binding CBCR GAF domains receive considerable attention for their in vivo optogenetic and bioimaging applications because BV is a mammalian intrinsic chromophore and can absorb far-red light that penetrates deep into the mammalian body.

Development of non-electrically controlled SalivaDirect LAMP (NEC-SD-LAMP), a new nonelectrical infectious disease testing method.

In this study, non-electrically controlled SalivaDirect loop-mediated isothermal amplification (NEC-SD-LAMP), which can detect infections by amplifying viral DNA expression in saliva without using electrical control systems, was developed. By this method, only by adding water to the device, viral DNA was extracted from saliva using SalivaDirect, the extracted DNA was amplified via loop-mediated isothermal amplification (LAMP), and the results were visually confirmed. Melting palmitic acid maintained the optimal temperature for the LAMP reaction, as the temperature of palmitic acid is maintained at 62.

WUSCHEL-RELATED HOMEOBOX 13 suppresses de novo shoot regeneration via cell fate control of pluripotent callus.

Plants can regenerate their bodies via de novo establishment of shoot apical meristems (SAMs) from pluripotent callus. Only a small fraction of callus cells is eventually specified into SAMs but the molecular mechanisms underlying fate specification remain obscure. The expression of WUSCHEL (WUS) is an early hallmark of SAM fate acquisition.

Interfacial Molecular Compatibility for Programming Organic-Metal Oxide Superlattices.

Artificially programming a sequence of organic-metal oxide multilayers (superlattices) by using atomic layer deposition (ALD) is a fascinating and challenging issue in material chemistry. However, the complex chemical reactions between ALD precursors and organic layer surfaces have limited their applications for various material combinations. Here, we demonstrate the impact of interfacial molecular compatibility on the formation of organic-metal oxide superlattices using ALD.
