Nanoarchitectonics of vanadium nanoparticles decorated mesoporous carbon nitride in photocatalytic systems: A study on ethylbenzene oxidation reaction.

In this work, we have described the synthesis of vanadium (V) nanoparticles (NPs) anchored on mesoporous graphitic carbon nitride (V@mpg-CN) and their uses in photocatalytic ethylbenzene oxidation to the respective acetophenones. The mpg-CN serves as the support for the decoration of V NPs, through a simple impregnation method. Various advanced techniques, such as XRD, UV-vis spectrometry, HRTEM, HAADF-STEM, AC-STEM, elemental mapping, and BET surface area analysis, were employed for the characterization of V@mpg-CN.

Harnessing photocatalytic activity of mesoporous graphitic carbon nitride decorated by copper single-atom catalysts for oxidative dehydrogenation of N-heterocycles.

This work describes the application of Cu single-atom catalysts (SACs) for photocatalytic oxidative dehydrogenation of N-heterocyclic amines to the respective N-heteroaromatics through environmentally benign and sustainable pathways. The mesoporous graphitic carbon nitride (mpg-CN), prepared by the one-step pyrolysis method, possesses a lightweight material with a high surface area (95 m g) and an average pore diameter (3.6 nm).

Déjerine-Roussy syndrome presenting with atypical involuntary movements.

Background: The Déjerine-Roussy syndrome is caused by a stroke in the posterior lateral nuclei of the thalamus. It has a 17 to 18% prevalence after a stroke involving the inferior lateral thalamus.

Methods: We reported a case of a 65-year-old, diabetic and hypertensive male who presented with sudden onset of superficial hemianesthesia, allodynia, severe and paroxysmal pain on the right side of the body with choreoathetoid movements in the upperN limb, along with slured speech, and unsteadiness while walking.

A Case of Hypermotor Seizures in Posterior Insular Cortex Epilepsy.

Insular seizure is a rare entity. Insular spikes spread to the temporal, parietal, and frontal lobes and clinically manifest with seizure semiology specific to these areas. We report the case of a 19-year-old male patient who presented with complaints of left-sided hemimotor tonic-clonic focal seizures of the limbs occurring three times per day.

Metronidazole-Induced Encephalopathy (MIE).

Metronidazole is an antibiotic often used to treat bacterial infections in the vagina, skin, liver, stomach, joints, brain and spinal cord, heart, lungs, or bloodstream. It is an essential drug for treating anaerobic bacterial infections, microaerophilic bacterial infections, and protozoal infections. It is cytotoxic to many facultative anaerobic microorganisms.

An Atypical Presentation of Left Lateral Medullary Syndrome - A Case Report.

Lateral medullary syndrome (LMS), known as Wallenberg's syndrome and posterior inferior cerebellar artery syndrome, is a rare cause of stroke. It often results from thrombosis or emboli of the vertebral artery or posterior inferior cerebellar artery. The triad of Horner's syndrome, ipsilateral ataxia, and ipsilateral hyperalgesia clinically identify patients with LMS.

Severe acute orthostatic headache: spontaneous intracranial hypotension (SIH).

The most common cause of spontaneous intracranial hypotension headache is a cerebrospinal fluid (CSF) leakage, but the underlying mechanisms remain unknown. Intracranial hypotension is characterised by diffuse pachymeningeal enhancement on cranial MRI features, low CSF pressure and orthostatic headaches mostly caused by the dural puncture. We report a 31-year-old woman who presented to our services with reports of continuous severe bifrontal headache, which increased on sitting up and resolved on lying down.

Paraneoplastic Cerebellar Degeneration Associated With Ovarian Adenocarcinoma: A Case Report and Review of Literature.

Paraneoplastic syndromes are a rare heterogeneous group of disorders that are indicators of the underlying occult malignancy. Subacute cerebellar ataxia in a patient with a known cancer is often due to metastatic invasion or other complications of the cancer, such as infection, coagulopathy, metabolic and nutritional deficits, or side effects of treatment. When tumor- and treatment-related causes have been excluded, the patient is considered to suffer from paraneoplastic cerebellar degeneration (PCD).

Neurology of renal disorders.

Chronic kidney disease (CKD) is a critical and rapidly growing global health problem. Neurological complications occur in almost all patients with severe CKD, potentially affecting all levels of the nervous system, from the central nervous system (CNS) through to the peripheral nervous system (PNS). Patients with CKD exhibit a high incidence of symptomatic and occult cerebrovascular diseases, associated tremendously high levels of inflammatory factors and homocysteine, as well as anemia, hypertension, and diabetes.

Brain Abscess in an Immunocompetent Old Patient: A Case Report and Review of Literature.

By definition, a brain abscess is an intraparenchymal collection of pus. Nocardia shows to have a special tropism for the neural tissue. Solitary abscess represents the most common manifestation in the central nervous system, accounting for 1%-2% of all cerebral abscesses.

Effect of different antioxidant additives in semen diluent on cryopreservability (-196°C) of buffalo semen.

Aim: The aim of this study was to evaluate the effect of different antioxidant additives in standard tris-fructose-egg yolk-glycerol (TFYG) extender on the cryopreservability of buffalo semen.

Materials And Methods: Semen collection using artificial vagina, twice weekly for 5 weeks from three pedigreed health breeding bulls of Mehsani breed, aged between 6 and 8 years. Immediately after initial evaluation all 30 qualifying ejaculates (10/bull) were split into three aliquots and diluted at 34°C keeping the concentration of 100 million spermatozoa/ml with standard TFYG extender as control and TFYG having two antioxidant additives - Cysteine HCl at 1 mg/ml and ascorbic acid at 0.

Cognitive Impairment After Stroke.

Background: Vascular dementia is extremely common and contributes to stroke-associated morbidity and mortality. The study of vascular dementia may help to plan preventive interventions.

Aims: To study the frequency of cognitive impairment after stroke in a series of consecutive patients with acute stroke, along with factors which influence it.
