When sng meets acupuncture -- a paradigm-shift biomarker for translational research.

The sensation of sng (pronounced/səŋ/, the Romanization form of or soreness in Taiwanese Southern Min) associated with a composite of unique sensations, is a novel phenotype for acupoint stimulation. It is perceived by test participants but also by experienced practitioners as a sensation of "taking the bait" (by fish when fishing), a characteristic heavy and tight sensation from the needle. Here, we propose that sng is a powerful biomarker for associated with successful manual acupuncture.

Bilateral inverse canine impaction: a case report.

Background: Maxillary canine impaction can result in malocclusion, temporomandibular joint complications, and esthetic concerns, thus influencing craniofacial development. Although cases of impacted canines are not uncommon in clinical practice, the likelihood of simultaneous bilateral impaction is extremely low; very few reports have documented cases of bilaterally symmetrical, inversely impacted canines.

Case Presentation: This paper reports a rare case of maxillary canine impaction, a condition characterized by the abnormal eruption of teeth.

Effect of Advillin Knockout on Diabetic Neuropathy Induced by Multiple Low Doses of Streptozotocin.

Advillin is an actin-binding protein involved in regulating the organization of actin filaments and the dynamics of axonal growth cones. In mice, advillin is exclusively expressed in somatosensory neurons, ubiquitously expressed in all neuron subtypes during neonatal ages and particularly enriched in isolectin B4-positive (IB4+) non-peptidergic neurons in adulthood. We previously showed that advillin plays a key role in axon regeneration of somatosensory neurons during peripheral neuropathy.

Effects of urinary organophosphate flame retardants in susceptibility to attention-deficit/hyperactivity disorder in school-age children.

Our previous studies have revealed a correlation between urinary phthalates (PAE) metabolites and parabens and PM exposure and susceptibility to attention-deficit/hyperactivity disorder (ADHD) in school-age children. Our goal was to examine the relationships between urinary organophosphate flame retardants (OPFRs) and their metabolites and the susceptibility to ADHD in the same cohort of children. We recruited 186 school children, including 132 with ADHD and 54 normal controls, living in southern Taiwan to investigate five OPFRs (1,3-dichloro-2-propyl phosphate (TDCPP), tri-n-butyl phosphate (TnBP), tris (2-chloroethyl) phosphate (TCEP), tris(2-butoxyethyl) phosphate (TBEP), and triphenyl phosphate (TPHP)) and five OPFR metabolites (bis(1,3-dichloro-2-propyl) phosphate (BDCPP), di-n-butyl phosphate (DNBP), bis(2-chloroethyl) hydrogen phosphate (BCEP), di-(2-butoxyethyl) phosphate (DBEP), and diphenyl phosphate (DPHP)) in urine.

Exogenous Janus Kinase 617 Codon Influences Small Noncoding RNAs and Gene Expression in Ba/F3 Cells.

Myeloproliferative neoplasms (MPNs) are blood cancers caused by mutations that originate from hematopoietic stem cells. More than 50%-90% of MPN patients had a dominant negative valine (V) to phenylalanine (F) mutation at the Janus kinase 617 codon (JAK2V617F) within the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) signaling pathway; however, this mutation was also found in a high percentage of the general population, its penetrance varied, and its onset was shown to be polygenic. Consequently, it is still unknown what molecular mechanism underlies the MPN transformation produced by JAK2V617F.

Presynaptic Enhancement of Transmission from Nociceptors Expressing Nav1.8 onto Lamina-I Spinothalamic Tract Neurons by Spared Nerve Injury in Mice.

Alteration of synaptic function in the dorsal horn (DH) has been implicated as a cellular substrate for the development of neuropathic pain, but certain details remain unclear. In particular, the lack of information on the types of synapses that undergo functional changes hinders the understanding of disease pathogenesis from a synaptic plasticity perspective. Here, we addressed this issue by using optogenetic and retrograde tracing ex vivo to selectively stimulate first-order nociceptors expressing Nav1.

Association of JAK2V617F allele burden and clinical correlates in polycythemia vera: a systematic review and meta-analysis.

Janus kinase 2 (JAK2) V617F mutation is present in most patients with polycythemia vera (PV). One persistently puzzling aspect unresolved is the association between JAK2V617F allele burden (also known as variant allele frequency) and the relevant clinical characteristics. Numerous studies have reported associations between allele burden and both hematologic and clinical features.

Treatment outcome and germline predictive factors of ropeginterferon alpha-2b in myeloproliferative neoplasm patients.

Background: Studies have shown that some single nucleotide polymorphisms (SNPs) could serve as excellent markers in foretelling the treatment outcome of interferon (IFN) in myeloproliferative neoplasms (MPN). However, most work originated from western countries, and data from different ethnic populations have been lacking.

Methods: To gain insights, targeted sequencing was performed to detect myeloid-associated mutations and SNPs in eight loci across three genes (IFNL4, IFN-γ, and inosine triphosphate pyrophosphatase [ITPA]) to explore their predictive roles in our cohort of 21 ropeginterferon alpha-2b (ROPEG)-treated MPN patients, among whom real-time quantitative PCR was also performed periodically to monitor the JAK2V617F allele burden in 19 JAK2V617F-mutated cases.

Heart Murmur Classification Using a Capsule Neural Network.

The healthcare industry has made significant progress in the diagnosis of heart conditions due to the use of intelligent detection systems such as electrocardiograms, cardiac ultrasounds, and abnormal sound diagnostics that use artificial intelligence (AI) technology, such as convolutional neural networks (CNNs). Over the past few decades, methods for automated segmentation and classification of heart sounds have been widely studied. In many cases, both experimental and clinical data require electrocardiography (ECG)-labeled phonocardiograms (PCGs) or several feature extraction techniques from the mel-scale frequency cepstral coefficient (MFCC) spectrum of heart sounds to achieve better identification results with AI methods.

Myalgia! Where does it come from?

Myalgia (also called muscle pain or muscle ache) is a symptom associated with many diseases, including fibromyalgia, neurodegenerative diseases, degenerative spine diseases, etc. Myalgia is a major medical problem affecting 60~85% of the population (lifetime prevalence). However, our understanding of chronic myalgia is still limited and effective treatment for intractable myalgia like fibromyalgia is still lacking.

Levels of organophosphate flame retardants and their metabolites among 391 volunteers in Taiwan: difference between adults and children.

This cross-sectional study aimed to develop a culturally sensitive Chronic Pain Cognition Scale (CPCS) for Chinese-/Chinese dialect-speaking populations and investigate its psychometric properties.

Patients And Methods: Adult patients with chronic low back pain or chronic neck pain who visited pain clinics at a medical center in northern Taiwan were enrolled.

Probing the Effect of Acidosis on Tether-Mode Mechanotransduction of Proprioceptors.

Proprioceptors are low-threshold mechanoreceptors involved in perceiving body position and strain bearing. However, the physiological response of proprioceptors to fatigue- and muscle-acidosis-related disturbances remains unknown. Here, we employed whole-cell patch-clamp recordings to probe the effect of mild acidosis on the mechanosensitivity of the proprioceptive neurons of dorsal root ganglia (DRG) in mice.

Novel Pulsed Ultrahigh-frequency Spinal Cord Stimulation Inhibits Mechanical Hypersensitivity and Brain Neuronal Activity in Rats after Nerve Injury.

Background: Spinal cord stimulation (SCS) is an important pain treatment modality. This study hypothesized that a novel pulsed ultrahigh-frequency spinal cord stimulation (pUHF-SCS) could safely and effectively inhibit spared nerve injury-induced neuropathic pain in rats.

Methods: Epidural pUHF-SCS (± 3V, 2-Hz pulses comprising 500-kHz biphasic sinewaves) was implanted at the thoracic vertebrae (T9 to T11).

Role of proprioceptors in chronic musculoskeletal pain.

Proprioceptors are non-nociceptive low-threshold mechanoreceptors. However, recent studies have shown that proprioceptors are acid-sensitive and express a variety of proton-sensing ion channels and receptors. Accordingly, although proprioceptors are commonly known as mechanosensing neurons that monitor muscle contraction status and body position, they may have a role in the development of pain associated with tissue acidosis.
