The present study investigated changes in autonomic nervous system activity and emotions after a short (2 h) forest bathing program in the Xitou Nature Education Area (XNEA), Taiwan. One hundred and twenty-eight (60.0 ± 7.44 years) middle-aged and elderly participants were recruited. Physiological responses, pulse rate, systolic and diastolic blood pressure, heart rate variability (HRV), and psychological indices were measured before and after the program. We observed that pulse rate, systolic and diastolic blood pressure were significantly lower after the program, which indicated physiological benefits from stress recovery...

Following traumatic brain injury (TBI), ischemia and hypoxia play a major role in further worsening of the damage, a process referred to as 'secondary injury'. Protecting neurons from causative factors of secondary injury has been the guiding principle of modern TBI management. Stimulation of trigeminal nerve induces pressor response and improves cerebral blood flow (CBF) by activating the rostral ventrolateral medulla. Moreover, it causes cerebrovasodilation through the trigemino-cerebrovascular system and trigemino-parasympathetic reflex...

Estrogens have an important role in regulating detrusor smooth muscle (DSM) function. However, the underlying molecular and cellular mechanisms by which estrogens control human DSM excitability and contractility are not well known. Here, we used human DSM specimens from open bladder surgeries on 27 patients to elucidate the mechanism by which 17β-estradiol regulates large conductance voltage- and Ca(2+)-activated K(+) (BK) channels, the most prominent K(+) channels in human DSM We employed single BK channel recordings on inside-out excised membrane patches, perforated whole-cell patch-clamp on freshly isolated DSM cells, and isometric tension recordings on DSM-isolated strips to investigate the mechanism by which 17β-estradiol activates BK channels...

Normal tension glaucoma (NTG) also known as low tension glaucoma, presents with optic nerve head and visual field damage in the absence of high intraocular pressure (<21 mmHg). There are several patients of NTG seen in our clinics who have repeatable visual field defects, which may or may not correlate with the disc appearance, but are labeled as glaucoma. Ruling out ischemic, nutritional, and other causes of one-time damage are important before diagnosing an NTG. We report 3 such cases that were misdiagnosed and referred as NTG...

Glaucoma, one of the leading causes of irreversible blindness, is characterized by progressive degeneration of optic nerves and retinal ganglion cells (RGCs). In the mammalian retina, excitatory amino-acid carrier 1 (EAAC1) is expressed in neural cells, including RGCs. Loss of EAAC1 leads to RGC degeneration without elevated intraocular pressure (IOP) and exhibits glaucomatous pathology including glutamate neurotoxicity and oxidative stress. In the present study, we found that edaravone, a free radical scavenger that is used for treatment of acute brain infarction and amyotrophic lateral sclerosis (ALS), reduces oxidative stress and prevents RGC death and thinning of the inner retinal layer in EAAC1-deficient (KO) mice...

AIMS: Mechanoafferent and peristaltic mechanisms of the human ureter involve transient receptor potential V1 (TRPV1)- and purinoceptor-mediated functions. Hydrogen sulphide, an endogenous TRPA1 ligand, is linked to inhibitory neurotransmission of the pig ureter. No information is available on TRPA1 activity in the human ureter. We therefore examined the distribution and function of TRPA1 in the human ureter. METHODS: Expression of TRPA1 in human ureter tissue was studied by Western blot and immunofluorescence...

Botulinum neurotoxin A (BoNT/A) cleaves SNAP25 at the motor nerve terminals (MNT) and inhibits stimulus evoked acetylcholine release (SEAR). This causes skeletal muscle paralysis. However, younger neonatal mice (<P7; less than 7 days old) are resistant to the neuroparalytic effects of BoNT/A. That is, in vivo injection of BoNT/A at the innervations of Extensor digitorum longus (EDL) muscle in the hindlimbs inhibited the toe spread reflex within 24 hours following BoNT/A injection in adult mouse and in older (> P7) neonatal mice younger than 7 days-age remained unaffected by BoNT/A injection...

Although vitamins play a major role in health, and their deficiency may be linked to symptoms of optic-nerve dysfunction, the association between serum vitamin levels and glaucoma in humans remains controversial. In this study, articles in the PubMed, Web of Science, and EMBASE databases were searched up to 25March 2017. Nine studies on primary open-angle glaucoma (POAG), four studies on normal tension glaucoma (NTG), and six studies on exfoliative glaucoma (EXG) were retrieved. The combined results showed no differences in the levels of serum vitamin B₆ between POAG (p = 0...

In the context of lower (C8-T1) brachial plexus injury, transfer of the lateral antebrachial cutaneous nerve (LABCN) to the dorsal branch of the ulnar nerve (DBUN) with an interposed sural nerve graft has been proposed to restore sensitivity on the ulnar side of the hand. The purpose of this study was to assess the feasibility of performing this transfer directly - without interposition of a nerve graft - by intraneural dissection of the DBUN. An anatomical study was performed with 20 upper limbs from adult human cadavers...

A response, i.e., the supragastric belch (SGB), in which a belch occurs without gastric involvement has been characterized in humans. The aims of this study were to determine whether animals have an SGB and if so to determine its mechanisms. Studies were conducted in decerebrate cats (N=30) with EMG electrodes on hyoid, pharyngeal, esophageal, and diaphragm muscles. The effects of distending different regions of the esophagus in different manners using a balloon were quantified to determine the most appropriate stimulus for activating the cat SGB...

Previous research has indicated that differences in sensitivities to muscle relaxants exist between facial nerve- and somatic nerve-innervated muscles. Here, we report that the 50% inhibitory concentration (IC50) values for rocuronium were significantly larger in the normal orbicularis oris than those in the gastrocnemius. Increased IC50 values and reduced twitch tension were observed after facial nerve injury. The normal orbicularis oris had a smaller muscle fiber cross-sectional area (CSA) and a larger ratio of endplate surface area (ESA) to muscle fiber CSA (ESA/CSA), but no difference was found in the density of nicotinic acetylcholine receptor (nAChR) subunits on endplates between normal orbicularis oris and gastrocnemius...

The mammalian pupillary light reflex (PLR) involves a bilateral brain circuit whereby afferent light signals in the optic nerve ultimately drive iris-sphincter-muscle contraction via excitatory cholinergic parasympathetic innervation [1, 2]. Additionally, the PLR in nocturnal and crepuscular sub-primate mammals has a "local" component in the isolated sphincter muscle [3-5], as in amphibians, fish, and bird [6-10]. In mouse, this local PLR requires the pigment melanopsin [5], originally found in intrinsically photosensitive retinal ganglion cells (ipRGCs) [11-19]...
