Rituximab (monoclonal anti-CD20 antibody) induced posterior reversible encephalopathy syndrome (PRES): A case report and literature review.

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological condition characterized by reversible subcortical vasogenic edema that primarily affects the posterior areas of the brain. Subcortical vasogenic edema resulting from endothelial injury and hypertension is the pathogenesis. Here, we present a 23-year-old female patient with systemic lupus erythematosus (SLE) and lupus nephritis who developed PRES following Rituximab (a monoclonal anti-CD-20 antibody) administration.

Photo-thermo-optical modulation of Raman scattering from Mie-resonant silicon nanostructures.

Raman scattering is sensitive to local temperature and thus offers a convenient tool for non-contact and non-destructive optical thermometry at the nanoscale. In turn, all-dielectric nanostructures, such as silicon particles, exhibit strongly enhanced photothermal heating due to Mie resonances, which leads to the strong modulation of elastic Rayleigh scattering intensity through subsequent thermo-optical effects. However, the influence of the complex photo-thermo-optical effect on inelastic Raman scattering has yet to be explored for resonant dielectric nanostructures.

Left Anterolateral Medullary Compression Due to Vertebral Artery Dolichoectasia: A Case Report and Review of Literature.

Vertebral artery dolichoectasia, characterized by the elongation, dilation, and tortuosity of the vertebral arteries, poses significant clinical challenges due to its potential to compress adjacent neural structures, particularly the medulla oblongata. This case report presents a 73-year-old hypertensive female with recurrent episodes of falls and transient loss of consciousness. Initial assessments including echocardiography and a four-vessel Doppler study were unremarkable, prompting further evaluation with MRI.

The Role of Plain CT in Assessing and Estimating Normal Values of Pericardial Fat Pad Thickness and Their Correlation With Patient's Age, Gender, Body Weight, and Body Mass Index.

Introduction The pericardial fat pad, located anteriorly to the heart between the pericardium and myocardium, has garnered significant interest in cardiovascular research due to its potential role in the pathophysiology of various cardiac conditions. Despite its proximity to the myocardium, it is distinct from the epicardial fat depot found between the myocardium and the visceral layer of the pericardium. Studies have shown that excess pericardial fat is associated with an increased risk of heart failure and other cardiovascular diseases.

Radiological Insights From Two Distinct Cases of Pineal Region Meningioma: A Case Report.

This case report delineates the radiological evaluation and diagnostic intricacies of two unique cases of pineal region meningioma, underscoring the pivotal role of advanced imaging techniques in the accurate diagnosis and management of such rare tumors. Pineal region tumors represent a heterogeneous group of neoplasms, with meningiomas in this location being particularly uncommon, thereby posing significant challenges in diagnosis and therapeutic decision-making. The first case involves a 40-year-old female presenting with progressive headaches and visual disturbances with symptoms of increased intracranial pressure, whereas the second case describes a 30-year-old male presenting with headache, dizziness, difficulty with balance, and cognitive decline.

Enhancing the performance of a solar air heater by employing the broken V-shaped ribs.

This work aims to enhance the performance of a solar air heater (SAH) by introducing broken V-ribs as roughness elements on the absorber plate. The unit with a conventional flat absorber plate is referred to as the "FSAH," while the unit with a broken V-rib-shaped absorber plate is called the "VSAH." The experiment was performed for three air velocities: 25 m/s, 20 m/s, and 15 m/s and the corresponding air flow rates were 0.

Performance amelioration of single basin solar still integrated with V- type concentrator: Energy, exergy, and economic analysis.

Solar desalination is one of the most sustainable solutions to produce freshwater from brackish water. The present research work aims to experimentally investigate the effect of a V-shape concentrator integrated with solar still (SS). The V-shape concentrator integrated with the conventional solar still (CSS) is used to supply the saline water at elevated temperature to the basin of SS, which augments the freshwater yield compared to CSS.

Comparison of pectoral Nerve (PECS1) block with combined PECS1 and transversus thoracis muscle (TTM) block in patients undergoing cardiac implantable electronic device insertion - A pilot study.

Background: Pectoral nerve (PECS1) block has been used for patients undergoing cardiac implantable electronic device (CIED) insertions, however, PECS1 block alone may lead to inadequate analgesia during tunneling and pocket creation because of the highly innervated chest wall. Transversus thoracis muscle plane (TTM) block targeting the anterior branches of T2-T6 intercostal nerves can be effectively used in combination with PECS1 for patients undergoing CIED insertion. The present study hypothesized that combined PECS1 and TTM blocks would provide effective analgesia for patients undergoing CIED insertion compared to PECS1 block alone.

Prevalence of Different Types of Apical Root Canal Morphology and their Treatment Recommendations in an Institute.

Introduction: Canals can be of different shapes in cross section including round canals, oval canals, long oval canals or ribbon shaped canals. Recesses of nonround canals may not be included in the round preparation created by rotary instruments and thus they remain unprepared. The aim of this study included determination of shape and taper of the apical root canal based on diameter at different levels.

Hemodynamic Responses at Intubation, Change of Position, and Skin Incision: A Comparison of Multimodal Analgesia with Conventional Analgesic Regime.

Background: Lumbar spine surgery is associated with hemodynamic variations at intubation, change of position, and skin incision. A balanced anesthesia with multimodal analgesia (MMA) is necessary to attenuate these changes.

Aim: To assess the relative effectiveness of preemptive MMA compared with the conventional analgesic regime in suppressing the hemodynamic response to endotracheal intubation, prone positioning, and skin incision.

A modified submental orotracheal intubation.

In patients with concomitant occurrence of maxillofacial and basilar skull fractures, open reduction and internal fixation is the treatment. It requires intermittent intra operative dental occlusion which precludes oral or nasal intubation. In such cases submental intubation (SMI) is a recognized technique in practice.

Dens Evaginatus: A Problem-Based Approach.

Dens evaginatus is an uncommon developmental anomaly of human dentition characterized by the presence of tubercle on the occlusal surface of mandibular premolars and lingual surface of anterior teeth. Due to occlusal trauma this tubercle tends to fracture thus exposing the pathway to the pulp chamber of teeth. This case report is about the presentation of dens evaginatus in mandibular premolars bilaterally; among them tooth 44 was associated with chronic apical periodontitis.

Evolution of the bovine TLR gene family and member associations with Mycobacterium avium subspecies paratuberculosis infection.

Members of the Toll-like receptor (TLR) gene family occupy key roles in the mammalian innate immune system by functioning as sentries for the detection of invading pathogens, thereafter provoking host innate immune responses. We utilized a custom next-generation sequencing approach and allele-specific genotyping assays to detect and validate 280 biallelic variants across all 10 bovine TLR genes, including 71 nonsynonymous single nucleotide polymorphisms (SNPs) and one putative nonsense SNP. Bayesian haplotype reconstructions and median joining networks revealed haplotype sharing between Bos taurus taurus and Bos taurus indicus breeds at every locus, and specialized beef and dairy breeds could not be differentiated despite an average polymorphism density of 1 marker/158 bp.

A three-component gene expression system and its application for inducible flavonoid overproduction in transgenic Arabidopsis thaliana.

Inducible gene expression is a powerful tool to study and engineer genes whose overexpression could be detrimental for the host organisms. However, only limited systems have been adopted in plant biotechnology. We have developed an osmotically inducible system using three components of plant origin, RD29a (Responsive to Dehydration 29A) promoter, CBF3 (C-repeat Binding Factor 3) transcription factor and cpl1-2 (CTD phosphatase-like 1) mutation.

Cervical solitary long segment cystic Schwannoma.

Cystic neurofibromas are very rare and are of separate entity; occurrence in the cervical spine extending over a long segment intra-durally is very rare. There is a paucity of literature available on cervical cystic Schwannoma and its MRI characteristics. As the preoperative diagnosis of these tumors helps in planning the surgery for this rare tumor the imaging findings reported herein may aid in the preoperative diagnosis and management.

Arabidopsis thaliana PRP40s are RNA polymerase II C-terminal domain-associating proteins.

The carboxyl-terminal domain (CTD) of the largest subunit of RNA polymerase II functions as a scaffold for RNA processing machineries that recognize differentially phosphorylated conserved (YSPTSPS)(n) repeats. Evidence indicates that proteins that regulate the phosphorylation status of the CTD are determinants of growth, development, and stress responses of plants; however, little is known about the mechanisms that translate the CTD phosphoarray into physiological outputs. We report the bioinformatic identification of a family of three phospho-CTD-associated proteins (PCAPs) in Arabidopsis and the characterization of the AtPRP40 (Arabidopsis thaliana PRE-mRNA-PROCESSING PROTEIN 40) family as PCAPs.

The Arabidopsis thaliana carboxyl-terminal domain phosphatase-like 2 regulates plant growth, stress and auxin responses.

More than 20 genes in the Arabidopsis genome encode proteins similar to phosphatases that act on the carboxyl-terminal domain (CTD) of RNA polymerase II. One of these CTD-phosphatase-like (CPL) proteins, CPL2, dephosphorylates CTD-Ser5-PO4 in an intact RNA polymerase II complex and contains a double-stranded (ds)-RNA-binding motif (DRM). Although the dsRNA-binding activity of CPL2 DRM has not been shown to date, T-DNA insertion mutants that express CPL2 variants lacking either a part of DRM (cpl2-1) or the entire DRM (cpl2-2) exhibited leaf expansion defects, early flowering, low fertility, and increased salt sensitivity.

Salt tolerance of Arabidopsis thaliana requires maturation of N-glycosylated proteins in the Golgi apparatus.

Protein N-glycosylation in the endoplasmic reticulum (ER) and in the Golgi apparatus is an essential process in eukaryotic cells. Although the N-glycosylation pathway in the ER has been shown to regulate protein quality control, salt tolerance, and cellulose biosynthesis in plants, no biological roles have been linked functionally to N-glycan modifications that occur in the Golgi apparatus. Herein, we provide evidence that mutants defective in N-glycan maturation, such as complex glycan 1 (cgl1), are more salt-sensitive than wild type.
