Multiplex one-step direct asymmetric PCR of blood and dual-labelled probe-mediated melting curve for genotyping of MTHFR and MTRR polymorphisms.

Accurate, rapid, and multiplex SNP analysis holds significant clinical value. However, the inevitable nucleic acid extraction, involving centrifugation, heating, and magnetic separation, is often time-consuming. In this study, direct blood PCR was combined with dual-labelled probe-mediated melting curves to identify SNPs corresponding to MTHFR (C677T, rs#1801133 and A1298C, rs#1801131) and MTRR (A66G, rs#1801394) in a single tube.

Arousal-promoting effect of the parabrachial nucleus and the underlying mechanisms: Recent advances.

The parabrachial nucleus (PBN) is responsible for integrating both internal and external sensory information and controlling/regulating a wide range of physiological processes, such as feeding, thermogenesis, nociceptive and pruritic sensations, and respiration. Recently, the PBN has been found to be involved in mediating wakefulness maintenance, sleep-wake transition, exogenous neuromodulation of awakening, and arousal-promoting process triggered by drastic changes in the internal environments, such as hypercapnia, hypoxia, and hypertension. Multiple neural pathways and subpopulations of neurons are responsible for arousal-promoting effects of the PBN.

An excitatory neural circuit for descending inhibition of itch processing.

Itch serves as a self-protection mechanism against harmful external agents, whereas uncontrolled and persistent itch severely influences the quality of life of patients and aggravates their diseases. Unfortunately, the existing treatments are largely ineffective. The current difficulty in treatment may be closely related to the fact that the central neural mechanisms underlying itch processing, especially descending inhibition of itch, are poorly understood.

Long noncoding RNA steroid receptor RNA activator 1 inhibits proliferation and glycolysis of esophageal squamous cell carcinoma.

Background: The clinical effects and detailed roles of long non-coding RNA (LncRNA) steroid receptor RNA activator 1 (SRA1) in esophageal squamous cell carcinoma (ESCC) remain ambiguous.

Effect of angled abutments in the posterior maxillary region on tilted implants: a 3D finite element analysis.

The aim of this study was to evaluate the bone tissue effects under dynamic loading using finite element analysis (FEA) for four angled abutments with different deviated palatal lateral tilt angles. A three-dimensional model of the posterior maxillary region and an implant crown model were reconstructed and assembled with a three-dimensional model of the implant, angled abutment, and central screw to create a total of 10 three-dimensional finite element models tilted at , , , and in three groups, and the dynamic loads simulating oral mastication were loaded on the implant crown to analyze the equivalent stresses and strains in the peri-implant bone tissues. Under the dynamic loading, the cortical bone on the buccal side of the implant neck showed different degrees of stress concentration, and the cortical bone stress was much higher than the cancellous bone, and the strain concentration area of each model was located in the bone tissue around the implant neck and base.

Prelimbic cortex-nucleus accumbens core projection positively regulates itch and itch-related aversion.

Itch is one of the most common clinical symptoms in patients with diseases of the skin, liver, or kidney, and it strongly triggers aversive emotion and scratching behavior. Previous studies have confirmed the role of the prelimbic cortex (Prl) and the nucleus accumbens core (NAcC), which are reward and motivation regulatory centers, in the regulation of itch. However, it is currently unclear whether the Prl-NAcC projection, an important pathway connecting these two brain regions, is involved in the regulation of itch and its associated negative emotions.
