Phosphodiesterase 9 (PDE9) is an enzyme that hydrolyzes cyclic guanosine monophosphate (cGMP)-a second messenger that regulates neuronal plasticity and memory function. PDE9 inhibition has been shown to enhance cognitive function in rodents, underlining the potential of PDE9 inhibitors (PDE9Is) as novel therapeutics for cognitive dysfunction. Considering the critical role of nitric oxide (NO)-cGMP signaling cascade in acetylcholine (ACh) release, the combination of PDE9Is and acetylcholinesterase inhibitors may synergistically elevate ACh levels in the brain.

It is being developed as a potential disease-modifying therapy for Alzheimer disease.
Methods: This randomized, placebo-controlled study comprised of 2 parts: single ascending doses evaluating 5 etalanetug doses and multiple ascending doses evaluating 4 fixed doses in each cohort, 8 healthy subjects were randomized (3:1) to single etalanetug dose or placebo.

Background: Disability in ambulation has a critical impact on activities of daily living in patients with multiple sclerosis (MS). The 12-item Multiple Sclerosis Walking Scale (MSWS-12) is a self-reported instrument developed to assess the impact of MS on walking. The scale's 12 items assess various aspects of walking-related tasks during the past 2 weeks.

Objective: The present study aimed to investigate the differences in walking and running parameters with and without backpacks in primary school children with and without BS.
Prcis: Large amount of trabeculotomy with Kahook Dual Blade (KDB) confers better intraocular pressure (IOP) lowering.
Purpose: We compared the postoperative outcomes of trabeculotomy using the KDB in patients with exfoliation glaucoma (EXG) and primary open angle glaucoma between the 120-degree incision and the 210- to 240-degree incision groups.
Patients And Methods: We retrospectively analyzed the postoperative outcomes of trabeculotomy performed using the KDB in 101 eyes with EXG and primary open angle glaucoma, who received 120- and 210- to 240-degree incisions at Kumamoto University Hospital between April 25, 2018, and August 11, 2021.
In animal species that have the capability of regenerating tissues and limbs, cell proliferation is enhanced after wound healing and is essential for the reconstruction of injured tissue. Although the ability to induce cell proliferation is a common feature of such species, the molecular mechanisms that regulate the transition from wound healing to regenerative cell proliferation remain unclear. Here, we show that upon injury, InhibinβA and JunB cooperatively function for this transition during Xenopus tadpole tail regeneration.

The first small interfering RNA (siRNA) therapeutic received approval for hereditary transthyretin (ATTRv) amyloidosis, and the patients' lifespan extension by specific inhibition of hepatic synthesis of transthyretin (TTR) is expected. However, ocular amyloidosis in these patients has been a crucial issue. This study aims to evaluate the efficacy and safety of intravitreal TTR siRNA conjugate injection into rabbit eyes.

[Participants and Methods] Semi-structured interviews were conducted with one doctor, three nurses, and six patients from a noncommunicable disease clinic on one island of the Kingdom of Tonga. The questions focused on the patients' exercise habits and perception of physical exercise.

Based on the Tube Versus Trabeculectomy study in refractory glaucoma results in 2012, tube shunt surgeries have been performed for UG, but few reports have focused on UG. We retrospectively examined the surgical efficacy, complications, and risk factors in 62 eyes with UG that underwent Baerveldt glaucoma drainage device (BGD) implantation at Kumamoto University.

Previous studies have pointed out the association of smoking with the development and worsening of symptoms in myasthenia gravis (MG), but further investigation is necessary to confirm this association. Smoking history was investigated in a cross-sectional study of 139 patients with anti-acetylcholine receptor antibody-positive MG, and the association of smoking history with the age at the onset of MG was analyzed.

On the other hand, physical and psychiatric symptoms are variable in people with MS, and QOL can be influenced by cultural and educational background. This study aimed to evaluate the association of HRQOL with disabilities, fatigue, and depression in Japanese subjects with MS.

Background: Cognitive dysfunction occurs in a substantial proportion of patients with multiple sclerosis (MS), negatively affects their daily activities, and is associated with poor prognosis. Cognitive dysfunction in MS can extend across multiple cognitive domains, depending on the patterns and extent of the brain regions affected. Therefore, a combination of tests, including the Brief International Cognitive Assessment for MS (BICAMS), that assess different aspects of cognition is recommended to capture the full picture of cognitive impairment in each patient.

Background: This study aimed to evaluate the association between cognitive impairment and health-related quality of life (HRQOL), fatigue, and depression in Japanese patients with multiple sclerosis (MS).
Methods: The Brief International Cognitive Assessment for MS (BICAMS) was performed in 184 Japanese patients with MS. The Functional Assessment of MS (FAMS), Fatigue Severity Scale (FSS), and Beck Depression Inventory-Second Edition (BDI-II) were used to evaluate HRQOL, fatigue, and depression, respectively.
Objective Smoking is a known risk factor for the development and progression of autoimmune diseases. Previous studies in ocular myasthenia gravis (MG) patients showed that smoking is associated with the severity of symptoms and progression to generalized MG. However, whether smoking affects MG symptoms in patients with a broader clinical spectrum of presentations is unknown.

Elevated intraocular pressure (IOP) is a significant risk factor for vision loss due to glaucoma, which is a major cause of blindness worldwide. Glaucoma filtration surgery (GFS) is an important method to reduce IOP by guidance of aqueous humor into a newly built filtration bleb in the conjunctiva; management of the wound healing mechanism is essential for the success of GFS. Here, we investigated the roles of interleukin (IL)-6 family members during the wound healing process after GFS.
