Mental nerve (MN) injury is the most common complications of genioplasty; to protect the MN and oral mucosa, the authors invent and validate the appropriate retractors for genioplasty, and which can avoid the skin and mucous membrane of the lower lip, chin, and the vestibular gingiva of the mandibular incisor from paresthesia or dysesthesia. The patent application for the appropriate retractors for genioplasty is already submitted (Patent No 201610164563.3, China). The retractors provide a better surgical visual field and improve the operation efficiency while reducing the risk of surgery...

BACKGROUND: Chronic pain and stress-related psychopathologies, such as depression and anxiety-associated abnormalities, are mutually reinforcing; however, the neuronal circuits and mechanisms that underlie this reinforcement are still not well understood. Pituitary adenylate cyclase activating polypeptide (PACAP; Adcyap1) and its cognate PAC1 receptor (Adcyap1r1) are expressed in peripheral nociceptive pathways, participate in anxiety-related responses and have been have been linked to posttraumatic stress disorder and other mental health afflictions...

Nerve growth factor (NGF) is an important member of the neurotrophin family and its alteration has been associated with psychiatric disorders. Functionality consists of the activities that an individual can perform, as well as their social participation, which is an important factor in analyzing the carrier living conditions of subjects with psychiatric suffering. Several studies have evaluated functionality in bipolar disorder; however, no studies have evaluated the functionality in other mental disorders...

Numb chin syndrome (NCS) is a rare yet potentially ominous sensory neuropathy in the distribution of the mental or inferior alveolar nerve characterized by unilateral hypoesthesia over the lower lip, chin and occasionally gingival mucosa. Recognizing NCS is clinically important as this may be a subtle sign of occult malignancy progression or heralding the relapses. It may also occur in benign disease, both systemic and dental in origin. Current expert opinion is that patients with NCS without apparent cause should be assumed to have a malignant etiology until proven otherwise Lossos and Siegal (1992) [1]...

Slow transit constipation (STC) is generally considered as a complex idiopathic disease affected by multiple factors synergistically. Primarily caused by the condition of gut dysmotility, the transit of intestinal contents turned so slow that the moisture absorption increases, defecation frequency decreases, bowel movement is weakened or even disappeared with or without abdominal distension, dry and hard stool. Its etiology and pathogenesis remains unclear.Recently some researches reported the pathogenesis may be associated with the changes of the enteric nervous system (ENS), such as the change or degeneration of intestinal nerve cells, gut glial cell damage and neurotransmitter changes...

Neurotrophins (NTs), a family of proteins including nerve growth factor, brain-derived neurotrophic factor (BDNF), neurotrophin-3, and neurotrophin-4, are essential for neural growth, survival, and differentiation, and are therefore crucial for brain development. Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by problems of inattention and/or hyperactivity-impulsivity. ADHD is one of the most common childhood onset psychiatric disorders. Studies have suggested that both genetic and environmental factors influence the development of the disorder, although the precise causes of ADHD have not yet been identified...

Hyponatremia, i.e. reduction of sodium level in the blood plasma below 135 mmol/L, is one of the most common electrolyte disorders occurring in people addicted to alcohol. Numerous psychopathological symptoms may be significantly associated with its occurrence. Since sodium is one of the main bioelements, which is responsible for proper neuromuscular excitability maintenance and contributes in nerve impulses conduction, sodium balance disorders may be related to a risk to basic life functions. The tested group included 100 alcohol dependent patients (M = 90, F = 10)...

Numb chin syndrome, also known as mental nerve neuropathy, is a rare sensory neuropathy characterized by paresthesia and hypoesthesia in the area supplied by the mental nerve and its branches. This syndrome may be the first symptom of underlying malignancy or the first sign of recurrence and metastasis in patients with preexisting cancer. In this article, we present two cases with bilateral numb chin syndrome as the first manifestation of Burkitt's lymphoma/leukemia and review the relevant literature. Numb chin syndrome should be considered as a warning sign and raise the suspicion for an underlying malignancy...

DHA is a key nutritional n-3 PUFA and needs to be supplied by the human diet. DHA is found in significant amounts in the retinal and neuronal cell membranes due to its high fluidity. Indeed, DHA is selectively concentrated in the synaptic and retinal membranes. DHA is deemed to display anti-inflammatory properties and to reduce the risk of CVD. Consumption of larger amounts of DHA appears to reduce the risk of depression, bipolar disorder, schizophrenia and mood disorders. Conversely, it has been shown that loss of DHA from the nerve cell membrane leads to dysfunction of the central nervous system in the form of anxiety, irritability, susceptibility to stress, dyslexia, impaired memory and cognitive functions, and extended reaction times...

: Synaptic neuropeptide and neurotrophin stores are maintained by constitutive bidirectional capture of dense-core vesicles (DCVs) as they circulate in and out of the nerve terminal. Activity increases DCV capture to rapidly replenish synaptic neuropeptide stores following release. However, it is not known whether this is due to enhanced bidirectional capture. Here experiments at the Drosophila neuromuscular junction, where DCVs contain neuropeptides and a bone morphogenic protein, show that activity-dependent replenishment of synaptic neuropeptides following release is evident after inhibiting the retrograde transport with the dynactin disruptor mycalolide B or photobleaching DCVs entering a synaptic bouton by retrograde transport...
