Pathophysiologic processes that localize to the cerebellum are described in both. There are limited studies investigating cerebellar structural changes in these conditions, largely because of inherent challenges in the efficiency of segmentation. METHODS We applied a novel multiatlas cerebellar segmentation method to T1-weighted images in 282 PD and 111 essential tremor patients to define 26 cerebellar lobule volumes. The severity of postural and resting tremor in both populations and gait and postural instability in PD patients were defined using subscores of the UPDRS and Washington Heights-Inwood Genetic Study motor scales. These clinical measurements were related to lobule volume size. Multiple comparisons were controlled using a false discovery rate method. RESULTS Group differences were identified between ET and PD patients, with reductions in deep cerebellar nucleus volume in ET versus reduced lobule VI volume in PD. In ET patients, lobule VIII was negatively correlated with the severity of postural tremor. In PD patients, lobule IV was positively correlated with resting tremor and total tremor severity. We observed differences in cerebellar structure that localized to sensorimotor lobules of the cerebellum. Lobule volumes appeared to differentially relate to clinical symptoms, suggesting important clinicopathologic distinctions between these conditions. These results emphasize the role of the cerebellum in tremor symptoms and should foster future clinical and pathologic investigations of the sensorimotor lobules of the cerebellum. © 2020 International Parkinson and Movement Disorder Society. © 2020 International Parkinson and Movement Disorder Society.BACKGROUND Seizures triggered by eating (STE) behavior are very rare in humans and have not been documented previously in dogs. OBJECTIVES To document the occurrence of STE in dogs and describe their clinical features. ANIMALS Ten client-owned dogs with STE diagnosed at 5 European referral centers. METHODS A call for suspected cases of STE was made online. This call was followed by a retrospective review of medical records, combined with a questionnaire to be completed by both the owner and the board-certified neurologist who made the diagnosis. Cases were included if >50% of the seizures that occurred were related to eating and if a minimum diagnostic evaluation for seizures had been performed. RESULTS Four cases only had STE and 6 cases had both STE and spontaneous seizures. Four of the dogs were retrievers. The most common seizure type was focal epileptic seizures evolving to become generalized. Nine dogs were diagnosed with idiopathic epilepsy. One dog had a presumptive diagnosis of glioma involving the margins of the parietal, temporal, and frontal cortex (the perisylvian region), an area known to have a key role in eating-associated epilepsy in people. Treatment strategies included a combination of pharmacological management and eating habit changes. CONCLUSIONS AND CLINICAL IMPORTANCE We have identified a form of reflex epilepsy in dogs, with STE behavior. Further studies are warranted to improve the characterization and management of STE. © 2020 The Authors.

Thus, it is important to precisely tune the photothermal and photodynamic effects of phototherapy nano-agents for efficient cancer treatment. Herein, a series of copolymeric nanoparticles (PPy-Te NPs) were facilely synthesized in situ through controlled oxidative copolymerization with different ratios of pyrrole to tellurophene by FeCl3. Impressively, the photothermal and photodynamic effects of semiconducting nano-agents under the first near-infrared (NIR) irradiation were precisely and systematically tuned upon simply varying the molar ratio of the pyrrole to tellurophene. Finally, the PPy-Te NPs were used for cancer treatment in mice, which exhibited excellent biocompatibility and therapeutic effect. This work presented a simple method to tune photothermal and photodynamic therapies effect in semiconducting nano-agents for cancer treatment. © 2020 WILEY-VCH Verlag GmbH & Co.

Alkyne 1,1-carboboration, the Wrackmeyer reaction, is an archetypal transformation of this kind. Solcitinib ic50 1,1-Carboboration has been proposed to proceed through a zwitterionic intermediate. We report the isolation and spectroscopic, structural and computational characterization of the zwitterionic intermediates generated by reaction of B(C6F5)3 with alkynes. The stepwise reactivity of the zwitterion provides new mechanistic insight for 1,1-carboboration and wider B(C6F5)3 catalysis. Making use of intramolecular stabilization by a ferrocene substituent, we have characterized the zwitterionic intermediate in the solid state and diverted reactivity towards alkyne cyclotrimerization. © 2020 WILEY-VCH Verlag GmbH & Co.

This size diversity can be explained by the evolutionary process of gene duplication and fusion. In this study we investigated a distorted β-propeller protein, an apparent intermediate between two symmetries. From this template, we created a perfectly symmetric 9-bladed β-propeller named Cake, using computational design and ancestral sequence reconstruction. The designed repeat sequence was found to be capable of generating both 8-fold and 9-fold propellers which are highly stable. Cake variants with 2 to 10 identical copies of the repeat sequence were characterized by X-ray crystallography and in solution. They were found to be highly stable, and to self-assemble into 8- or 9- fold symmetrical propellers. These findings show that the β-propeller fold allows sufficient structural plasticity to permit a given blade to assemble different forms, a transition from even to odd changes in blade number, and provide a potential explanation for the wide diversity of repeat numbers observed in natural propeller proteins.
