The real-time image processing in retinal prosthesis consists of the implementation of various image processing algorithms like edge detection, edge enhancement, decimation etc. The algorithmic computations in real-time may have high level of computational complexity and hence the use of digital signal processors (DSPs) for the implementation of such algorithms is proposed here. This application desires that the DSPs be highly computationally efficient while working on low power. DSPs have computational capabilities of hundreds of millions of instructions per second (MIPS) or millions of floating point operations per second (MFLOPS) along with certain processor configurations having low power. The various image processing algorithms, the DSP requirements and capabilities of different platforms would be discussed in this paper.

The effectiveness of a conservative approach in the management of groove pancreatitis.
Indian J Gastroenterol
January 2025
Department of Gastroenterology, Christian Medical College, Vellore, 632 517, India.
Background: Groove pancreatitis (GP) is a form of pancreatitis that affects the pancreaticoduodenal groove area, which lies between the head of the pancreas, the second part of the duodenum and the distal bile duct, presenting as abdominal pain and gastric outlet obstruction. In this study, we present the clinical and radiological characteristics of individuals diagnosed with groove pancreatitis at our center and discuss the use of a conservative treatment approach in managing GP.
Methods: The data of patients with groove pancreatitis treated at our center between January 2012 and December 2021 was analyzed.

Department of Orthopaedic Trauma, Hong Hui Hospital, Xi'an Jiaotong University School of Medicine, Xi'an, 710054, Shaanxi, China.
Background: Clavicle fractures associated with ipsilateral coracoid process fractures are very rare, with limited literature reporting only a few cases. This study reports on 27 patients with ipsilateral concomitant fractures of the clavicle and coracoid process who were followed for more than 12 months.
Material And Methods: This retrospective study reviewed the charts of skeletally mature patients with traumatic ipsilateral clavicle and coracoid process fractures treated at the authors' institution.
Comparison of the amyloid plaque proteome in Down syndrome, early-onset Alzheimer's disease, and late-onset Alzheimer's disease.

Down syndrome (DS) is strongly associated with Alzheimer's disease (AD) due to APP overexpression, exhibiting Amyloid-β (Aβ) and Tau pathology similar to early-onset (EOAD) and late-onset AD (LOAD). We evaluated the Aβ plaque proteome of DS, EOAD, and LOAD using unbiased localized proteomics on post-mortem paraffin-embedded tissues from four cohorts (n = 20/group): DS (59.8 ± 4.

Centre de recherche du Centre hospitalier de l'Université de Montréal (CRCHUM), Montréal, Québec H2X 0A9, Canada.
The abnormally viscous and thick mucus is a hallmark of cystic fibrosis (CF). How the mutated CF gene causes abnormal mucus remains an unanswered question of paramount interest. Mucus is produced by the hydration of gel-forming mucin macromolecules that are stored in intracellular granules prior to release.
