Integrated multi-operand optical neurons for scalable and hardware-efficient deep learning.

Optical neural networks (ONNs) are promising hardware platforms for next-generation neuromorphic computing due to their high parallelism, low latency, and low energy consumption. However, previous integrated photonic tensor cores (PTCs) consume numerous single-operand optical modulators for signal and weight encoding, leading to large area costs and high propagation loss to implement large tensor operations. This work proposes a scalable and efficient optical dot-product engine based on customized multi-operand photonic devices, namely multi-operand optical neuron (MOON).

Hump-shaped seven-core fiber-based WaveFlex biosensor for rapid detection of glyphosate pesticides in real food samples.

At present, pesticides are widely used in the cultivation of crops. Glyphosate is widely used in many pesticides. Glyphosate ingestion can cause a series of health problems.

Bioflavonoid combination attenuates diabetes-induced nephropathy in rats via modulation of MMP-9/TIMP-1, TGF-β, and GLUT-4-associated pathways.

Background: Diabetic nephropathy represents a significant microvascular complication of diabetes, characterized by extracellular matrix accumulation, loss of cell-cell junctions, microalbuminuria, and diminished creatinine clearance. Despite its prevalence, therapeutic options dedicated to this condition are currently lacking. Natural products like bioflavonoids have garnered attention for their potential therapeutic benefits.

Lab-on-a-chip optical biosensor platform: a micro-ring resonator integrated with a near-infrared Fourier transform spectrometer.

In this paper, we demonstrated the design and experimental results of the near-infrared lab-on-a-chip optical biosensor platform that monolithically integrates the MRR and the on-chip spectrometer on the silicon-on-insulator (SOI) wafer, which can eliminate the external optical spectrum analyzer for scanning the wavelength spectrum. The symmetric add-drop MRR biosensor is designed to have a free spectral range (FSR) of ∼19 nm and a bulk sensitivity of ∼73 nm/RIU; then the drop-port output resonance peaks are reconstructed from the integrated spatial-heterodyne Fourier transform spectrometer (SHFTS) with the spectral resolution of ∼3.1 nm and the bandwidth of ∼50 nm, which results in the limit of detection of 0.

Cyclodextrin Derivative Enhances the Ophthalmic Delivery of Poorly Soluble Azithromycin.

Azithromycin (AZM), a macrolide antibiotic used for the treatment of chlamydial conjunctivitis, is less effective for the treatment of this disease due to its poor bioavailability (38%). Various alternatives have been developed for improving the physicochemical properties (i.e.

Interictal autonomic changes in persons with epilepsy (PWE) on carbamazepine (CBZ) versus other anti-seizure drug monotherapy: A cross-sectional study.

Objective: Epilepsy is one of the most prevalent neurological conditions and carbamazepine is a commonly used anti-seizure drug (ASD), especially in developing nations. There are reports of carbamazepine causing atrioventricular conduction defects and autonomic dysfunctions and its implication in Sudden Unexpected Death in Epilepsy (SUDEP) is controversial. We planned this study to assess the effect of carbamazepine (CBZ) on autonomic function compared to other ASDs in persons with epilepsy.

Electrically writable silicon nanophotonic resistive memory with inherent stochasticity.

An electrically writable resistive memory with optical readout based on silicon nanophotonic structure is proposed. Hybridization of optical and surface plasmonic modes in the device enables nanoscale optical confinement to efficiently detect the resistive memory effect in a 13 nm thick SiO layer sandwiched between p-type silicon and gold. Electrical write and optical readout capabilities of the proposed device are experimentally demonstrated with well-defined optical and electrical hysteresis curves at a wavelength of 1550 nm.

Minicapsules encapsulating nanoparticles for targeting, apoptosis induction and treatment of colon cancer.

Cancer therapies are aimed at eliminating the rapidly growing tumor cells by surgery and radiotherapy. The present therapies are only fruitful in early identified cases. The present study involves the preparation and characterization of eudragit S100-coated mini-capsules filled with chitosan nanoparticles-unconjugated and folic acid (FA)-conjugated encapsulating caspase 3 activator (7-hydroxystaurosporine).

A Pocket-Friendly and Sustainable Iontophoresis Apparatus for Palmoplantar Hyperhidrosis: Advancement over a Previously Described Homemade Design.

Introduction And Objectives: Tap water iontophoresis is a promising therapy for palmoplantar hyperhidrosis. Non-affordability and nonavailability of the marketed device restrict its usage for many patients hailing from villages or small cities.

Materials And Methods: In an article named "A simple user-made iontophoresis device for palmoplantar hyperhidrosis" published previously in this journal, a simple inexpensive homemade device that runs on 12 V direct current battery was described.

Analysis and Clinical Importance of Skull Base Fractures in Adult Patients with Traumatic Brain Injury.

Aims And Objectives: Basal skull fracture (BSF) is rare in head injury (HI) patients and occasionally goes unnoticed which may lead to cerebrospinal fluid (CSF) fistula. With changing trends in HI, there is a need to reassess incidence and pattern of BSF pattern, CSF leak, meningitis, and management protocol, especially in this part of the world where detailed literature is lacking.

Subjects And Methods: We closely followed adult patients admitted with BSF in our institute between January 2013 and December 2014.

Safety of important dermatological drugs (retinoids, immune suppressants, anti androgens and thalidomide) in reproductively active males with respect to pregnancy outcome: A brief review of literature.

Paternally transmitted damage to offspring is recognized as a complex issue. Each parent contributes 23 chromosomes to a child; hence, it is necessary to know the effects of both maternal and paternal pre-and peri-conceptional exposure to drugs on pregnancy outcome. While there are many studies on the effects of maternal drug exposure on pregnancy outcome, literature on paternal exposure is scarce.

Topical Delivery of Erythromycin Through Cubosomes for Acne.

Background: Topical delivery is an attractive route for local and systemic treatment. The novel topical application has many advantages like averting the GI-irritation, preventing the metabolism of drugs in the liver and increasing the bioavailability of the drug over the conventional dosage forms.

Objective: The aim of present work was to prepare and characterized erythromycin encapsulated cubosomes using different concentrations of glyceryl monooleate and poloxamer 407 by the emulsification method.

Rationale Behind the Use of Double-Layer Polypropylene Patch (G-patch) Dural Substitute During Decompressive Craniectomy as an Adhesion Preventive Material for Subsequent Cranioplasty with Special Reference to Flap Elevation Time.

Objective: Dural substitutes are used in decompressive craniectomy (DC) to prevent adhesions during subsequent cranioplasty. Current literature attributes them to reduced blood loss and reduction in operative time of cranioplasty. The use of double-layer substitute has rarely been documented.

PEMLIF-a tale of two stories.

Intervertebral disc prolapse is a common cause of both acute and chronic low back pain. This can result in differential grades of motor and sensory disturbances in lower limbs and even cauda equina syndrome (CES). The neurological manifestations are a result of compression of the spinal cord and roots ventrally in the spinal canal due to the prolapsed disc.

Ewing Sarcoma of the Cervical Epidural Space Presenting with Tetraplegia: Case Report and Review of Literature.

Background: Ewing sarcoma (ES) is among the most frequented extremity osseous tumor in childhood. It was first described by James Ewing as diffuse endotheliomas in 1921. The name Ewing sarcoma was coined by Oberling in 1928 as a tribute to the legend who described this disease.

Single Parietal Burr-hole Craniostomy with Irrigation and Drainage for Unilateral Chronic Subdural Hematoma in Young Adults <40 Years: A Rationale behind the Procedure.
