Evaluation and Treatment of Patients with Small Posterior Cranial Fossa and Chiari Malformation, Types 0 and 1.

The diagnosis of Chiari I malformation is straightforward in patients with typical signs and symptoms of Chiari I malformation and magnetic resonance imaging (MRI) confirming ≥5 mm of cerebellar tonsillar ectopia, with or without a syrinx. However, in many cases, Chiari I malformation is discovered incidentally on MRI to evaluate global headache, cervical radiculopathy, or other conditions. In those cases, the clinician must consider if cerebellar tonsillar ectopia is related to the presenting symptoms.

[Plasma and salivary acetylcholinesterase activity in amyotrophic lateral sclerosis].

Objective: Assessment of plasma and salivary acetylcholinesterase (AChE) activity in patients with amyotrophic lateral sclerosis (ALS) and in an animal model of the disease.

Material And Methods: We studied 41 participants, aged 31 to 71 years, including 17 patients with diagnosed ALS (ALS group, average age 62.3±2.

[Treatment of cognitive, behavioral and mental disorders in patients with vascular dementia: results of a multicenter, randomized, double-blind, placebo-controlled clinical trial].

Objective: Evaluation of the efficacy and safety of Prospect in the treatment of cognitive, behavioral and mental disorders in patients with vascular dementia (VSD).

Material And Methods: In a double-blind, placebo-controlled, parallel-group randomised clinical trial, 406 patients aged 60-85 years old with a diagnosis of mild/moderate vascular dementia (10-24 on the Mini-Mental State Examination (MMSE)) and without signs of depression (Cornell Scale for Depression in Dementia (CSDD) scores ≤10) were included. At Visit 1, complaints and medical history were collected, vital signs were recorded, cognitive impairment was assessed using MMSE and MoCA, NPI-C and CSDD were completed, and an MRI brain scan was performed.

Seasonal dynamics of a complex cheilostome bryozoan symbiosis: vertical transfer challenged.

Symbiotic associations are dynamic systems influenced by both intrinsic and extrinsic factors. Here we describe for the first time the developmental and seasonal changes of the funicular bodies in the bryozoan Dendrobeania fruticosa, which are unique temporary organs of cheilostome bryozoans containing prokaryotic symbionts. Histological and ultrastructural studies showed that these organs undergo strong seasonal modification in the White Sea during the ice-free period.
