The efficacy of egg albumin nanoparticles adjuvanted Clostridium perfringens type D toxoid vaccine in rabbits.

Epsilon toxin (ETX) is an exotoxin produced by Clostridium perfringens type D that induces enterotoxaemia or necrotic intestinal infection in small ruminants and bovine. Immunization is an essential element in preventing the spread of infectious diseases. In recent literature, nanocarriers have exhibited the capacity to deliver protection, stability, and regulated distribution properties to protein-based antigens.

NS2B-D55E and NS2B-E65D Variations Are Responsible for Differences in NS2B-NS3 Protease Activities Between Japanese Encephalitis Virus Genotype I and III in Fluorogenic Peptide Model.

Japanese encephalitis virus (JEV) NS2B-NS3 is a protein complex composed of NS3 proteases and an NS2B co-factor. The N-terminal protease domain (180 residues) of NS3 (NS3(pro)) interacts directly with a central 40-amino acid hydrophilic domain of NS2B (NS2B(H)) to form an active serine protease. In this study, the recombinant NS2B(H)-NS3(pro) proteases were prepared in and used to compare the enzymatic activity between genotype I (GI) and III (GIII) NS2B-NS3 proteases.

Recapitulation of Peste des Petits Ruminants (PPR) Prevalence in Small Ruminant Populations of Pakistan from 2004 to 2023: A Systematic Review and Meta-Analysis.

Peste des petits ruminants (PPR) is an extremely transmissible viral disease caused by the PPR virus that impacts domestic small ruminants, namely sheep and goats. This study aimed to employ a methodical approach to evaluate the regional occurrence of PPR in small ruminants in Pakistan and the contributing factors that influence its prevalence. A thorough search was performed in various databases to identify published research articles between January 2004 and August 2023 on PPR in small ruminants in Pakistan.

Timing of development of osteoradionecrosis post head and neck radiotherapy: does a safe time interval exist for dental extraction?

Introduction: Risk factors for developing osteoradionecrosis (ORN) are well known, but less is known about factors influencing the interval between radiotherapy and the onset of ORN. Also, it is unknown whether there is any specific period post-radiotherapy with a reduced probability of ORN when irradiated teeth require extraction.

Purpose: The primary aim of this study was to identify factors influencing the interval in developing ORN in the following subgroups of patients: (1) patients who spontaneously developed ORN, (2) surgical-intervention-related ORN with a particular focus on patients after mandibulectomy.

Palmitoylation at Residue C221 of Japanese Encephalitis Virus NS2A Protein Contributes to Viral Replication Efficiency and Virulence.

Palmitoylation of viral proteins is crucial for host-virus interactions. In this study, we examined the palmitoylation of Japanese encephalitis virus (JEV) nonstructural protein 2A (NS2A) and observed that NS2A was palmitoylated at the C221 residue of NS2A. Blocking NS2A palmitoylation by introducing a cysteine-to-serine mutation at C221 (NS2A/C221S) impaired JEV replication and attenuated the virulence of JEV in mice.

A Case of Bilateral Adrenal Hemorrhage: The Exceptional Cause of Adrenal Insufficiency.

Bilateral adrenal hemorrhage is an extremely uncommon and life-threatening condition. It is caused by multiple etiologies, including antiphospholipid syndrome, disseminated histoplasmosis, trauma, severe stress, and granulomatous disease. The authors present a unique case of a 64-year-old alcoholic male, who was admitted after fall and right hip fracture.

Digoxin Use in Atrial Fibrillation; Insights From National Ambulatory Medical Care Survey.

The study evaluates the characteristics and trends of digoxin use during outpatient visits with atrial fibrillation in the US from 2006 to 2015.We conducted a retrospective analysis of adult (age >/= 18) patient visits to office-based physicians from National Ambulatory Medical Care Survey (NAMCS) database between 2006-2015. The International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify patients with Atrial fibrillation.

Can extended anticoagulation prophylaxis after discharge prevent thromboembolism?

A meta-analysis confirmed the benefit of thromboprophylaxis with a direct oral anticoagulant for high-risk nonsurgical patients after hospital discharge.

The interactions of flaviviruses with cellular receptors: Implications for virus entry.

Flaviviruses are a group of enveloped viruses that enter the host cells through receptor-mediated endocytosis. The entry of flaviviruses into the cells is a multi-step process which involves several host factors that trigger the uptake of the virus. The initial step in the virus life cycle is the interactions between viral envelope proteins and the specific receptors on the surface of host cell.

A Novel Recombinant Virus-Like Particles Displaying B and T Cell Epitopes of Japanese Encephalitis Virus Offers Protective Immunity in Mice and Guinea Pigs.

Virus-like particles (VLPs) are non-replicative vectors for the delivery of heterologous epitopes and are considered one of the most potent inducers of cellular and humoral immune responses in mice and guinea pigs. In the present study, VLP-JEVe was constructed by the insertion of six Japanese encephalitis virus (JEV) envelope protein epitopes into different surface loop regions of PPV VP2 by the substitution of specific amino acid sequences without altering the assembly of the virus; subsequently, the protective efficacy of this VLP-JEVe was evaluated against JEV challenge in mice and guinea pigs. Mice immunized with the VLP-JEVe antigen developed high titers of neutralizing antibodies and 100% protection against lethal JEV challenge.

The effects of unilateral transcranial direct current stimulation on unimanual laparoscopic peg-transfer task.

Introduction: Efficient training methods are required for laparoscopic surgical skills training to reduce the time needed for proficiency. Transcranial direct current stimulation (tDCS) is widely used to enhance motor skill acquisition and can be used to supplement the training of laparoscopic surgical skill acquisition. The aim of this study was to investigate the effect of anodal tDCS over the primary motor cortex (M1) on the performance of a unimanual variant of the laparoscopic peg-transfer task.

This study examines point and non-point sources of air pollution and particulate matter and their associated socioeconomic and health impacts in South Asian countries, primarily India, China, and Pakistan. The legislative frameworks, policy gaps, and targeted solutions are also scrutinized. The major cities in these countries have surpassed the permissible limits defined by WHO for sulfur dioxide, carbon monoxide, particulate matter, and nitrogen dioxide.

An Undiagnosed Case of Chronic Pancreatitis With Multiple Visceral Arteries Pseudoaneurysm.

Visceral artery aneurysms, which could be either true or pseudo, are abnormal focal dilations of vessels supplying the abdominal organs. True aneurysms, by definition, suggest dilation of the vessel in response to increased blood flow, ultimately causing a blood-filled sac to form. Pseudoaneurysm, however, is the pooling of blood in surrounding tissues secondary to trauma or rupture.

Newcastle disease virus (NDV) causes a highly contagious and devastating disease in poultry. ND causes heavy economic losses to the global poultry industry by decreasing the growth rate, decrease in egg production high morbidity and mortality. Although significant advances have been made in the vaccine development, outbreaks are reported in vaccinated birds.

Identification of Cleavage Sites Proteolytically Processed by NS2B-NS3 Protease in Polyprotein of Japanese Encephalitis Virus.

Understanding the proteolytic processing of polyprotein mediated by NS2B-NS3 protease contributes to the exploration of the mechanisms underlying infection of Japanese encephalitis virus (JEV), a zoonotic flavivirus. In this study, eukaryotic and prokaryotic cell models were employed to identify the cleavage sites mediated by viral NS2B-NS3 protease in JEV polyprotein. Artificial green fluorescent protein (GFP) substrates that contained the predicted cleavage site sequences of JEV polyprotein were expressed in swine testicle (ST) cells in the presence and absence of JEV infection, or co-expressed in with the recombinant NS2B-NS3 protease that was generated by fusing the N-terminal protease domain of NS3 to the central hydrophilic domain of NS2B.
