Switchable Polymerization from Monomer Mixtures to Synthesize Oxygen-Rich Block Copolymers with Dual Recyclability and Degradability.

Switchable catalysis from monomer mixtures has been emerging as a powerful technique to synthesize various useful block copolymers, yet represents a significant challenge in polymer chemistry. Herein, we present the synthesis of well-defined polyacetal/polycarbonate block copolymers through switchable polymerization from mixtures of terminal epoxides, internal epoxides, o-phthalaldehyde (OPA) and CO. The exclusive chemoselectivity of terminal epoxide or internal epoxide was achieved by controlling the reaction atmosphere.

Association between Body Mass Index and Medication-Overuse Headache among Individuals with Migraine: A Cross-Sectional Study.

Introduction: Medication-overuse headache (MOH) is a secondary chronic headache disorder that occurs in individuals with a pre-existing primary headache disorder, particularly migraine disorder. Obesity is often combined with chronic daily headaches and is considered a risk factor for the transformation of episodic headaches into chronic headaches. However, the association between obesity and MOH among individuals with migraine has rarely been studied.

Migraine-like headache in subjects with isolated Lambl's excrescences: a case series and literature review.

Aim: Lambl's excrescences are mobile, thin, fibrinous connective tissue strands typically found on left-sided cardiac values. Migraine is positively associated with structural cardiac anomalies. However, it remains unclear whether Lambl's excrescences are associated with migraine.

Status of diagnosis and preventative treatment for primary headache disorders: real-world data of unmet needs in China.

Background: There have been a few studies regarding the pre-attack symptoms (PAS) and pre-episode symptoms (PES) of cluster headache (CH), but none have been conducted in the Chinese population. The purpose of this study was to identify the prevalence and features of PAS and PES in Chinese patients, as well as to investigate their relationships with pertinent factors.

Methods: The study included patients who visited a tertiary headache center and nine other headache clinics between January 2019 and September 2021.

Galcanezumab in episodic migraine: the phase 3, randomized, double-blind, placebo-controlled PERSIST study.

Background: Galcanezumab, a humanized monoclonal antibody that binds calcitonin gene-related peptide, has demonstrated efficacy and good tolerability in patients with episodic migraine in previous phase 3 trials. We report results from the PERSIST study, which was designed to assess the efficacy and safety of galcanezumab in patients with episodic migraine from China, India, and Russia.

Methods: This phase 3 study was conducted at 40 centers in China (n = 26), India (n = 10), and Russia (n = 4).

Altered functional connectivity of the insula in a rat model of recurrent headache.

Migraine is a pain disorder accompanied by various symptoms. The insula, a “cortical hub,” is involved in many functions. Few studies have focused on the insula in migraine.

Atypical functional connectivity between the anterior cingulate cortex and other brain regions in a rat model of recurrent headache.

We explored the atypical functional connectivity between the anterior cingulate cortex and other brain areas in rats subjected to repeated meningeal nociception. The rat model was established by infusing an inflammatory soup through supradural catheters in conscious rats. Rats were subdivided according to the frequency of the inflammatory soup infusions.
