Primary dysmenorrhea (PDM) is the most prevalent gynecological disorder for women in reproductive age. PDM patients suffer from lower abdominal pain that starts with onset of menstrual flow. Prolonged nociceptive input to central nervous system can induce functional and structural alterations throughout system. In PDM, a chronic viscero-nociceptive drive cyclic nature, indications sensitization altered brain metabolism suggest substantial reorganization. Previously, we hypothesized...

In Brief Menstrual pain is the most prevalent gynecological complaint, and usually without organic cause (termed primary dysmenorrhea, PDM). The high comorbidity in later life of PDM with many functional disorders (associated central dysfunction inhibition, eg, fibromyalgia) suggests possible maladaptive functionality modulatory systems already occurred young women, making them vulnerable to disorders. Periaqueductal gray (PAG) matter functions as a critical hub neuraxis systems; therefore,...

Abstract Background The benefits of low-dose ketamine for patients with treatment-resistant depression (TRD) and prominent suicidal ideation require further investigation. effects treatment refractoriness, the duration current depressive episode, number prior antidepressant failures on efficacy also clarification. Methods We recruited 84 outpatients TRD ideation—defined as a score ≥4 item 10 Montgomery–Åsberg Depression Rating Scale (MADRS)—and randomized them into 2 groups to receive 0.5...

A novel aptamer-based label-free electrochemical impedance spectroscopy biosensor for 17β-estradiol has been fabricated. The aptamers were firstly immobilized on the gold electrode through Au-S interaction; aptamer probe was then bound with addition of to form estradiol/aptamer complex surface. This leads a significantly larger interfacial electron transfer resistance than that without 17β-estradiol. change in had linear relationship concentration range 1.0 × 10(-8) 10(-11) mol L(-1),...

Prefrontal left-right functional imbalance and disrupted prefronto-thalamic circuitry are plausible mechanisms for treatment-resistant depression (TRD). Add-on repetitive transcranial magnetic stimulation (rTMS), effective in treating antidepressant-refractory TRD, was administered to verify the core underlying refractoriness antidepressants. Thirty TRD patients received a 2-week course of 10-Hz rTMS left dorsolateral prefrontal cortex (DLPFC). Depression scores were evaluated at baseline...

This study investigates the cortical abnormalities of early emotion perception in patients with major depressive disorder (MDD) and bipolar (BD) using gamma oscillations. Twenty-three MDD patients, twenty-five BD twenty-four normal controls were enrolled their event-related magnetoencephalographic responses recorded during implicit emotional tasks. Our results demonstrated abnormal activity within 100 ms emotion-related regions (amygdala, orbitofrontal (OFC) cortex, anterior insula (AI),...

Abstract Primary dysmenorrhea (PDM) is the most prevalent gynecological problem. Many key brain systems are engaged in pain processing. In light of dynamic communication within and between (or networks) shaping experience behavior, intra-regional functional connectivity (FC) hub regions may be altered interactions terms inter-regional FCs among networks reorganized to cope with repeated stress menstrual PDM. Forty-six otherwise healthy PDM subjects 49 age-matched, female control were...

Nicotinamide N-methyltransferase (NNMT) plays multiple roles in improving the aggressiveness of colorectal cancer (CRC) and enhancing resistance to 5-Fluorouracil (5-FU), making it an attractive therapeutic target. Curcumin (Cur) is a promising natural compound, exhibiting antitumor effects potentiating effect 5-FU. The aim present study explore Cur on attenuating NNMT-induced 5-FU CRC. A panel CRC cell lines with different NNMT expressions are used characterize Cur. Herein, observed that...

Closed-loop neuromodulation is a promising personalized treatment for various neuropsychiatric disorders, delivering precise stimuli based on real-time brain signals. However, its clinical potential currently limited by technical challenges inherent in nature. This article addresses the primary EEG-Phase-Synchronized Transcranial Magnetic Stimulation (TMS), including poor stimulation accuracy and inefficient biomarker detection (correlated with deadlock). These arise from vulnerability of...

Abstract Visceral hypersensitivity in gastric fundus is a possible pathogenesis for functional dyspepsia. The cortical representation of still unclear. Growing evidence shows that the insula, but not primary or secondary somatosensory region (SI SII), may be target visceral pain.
