A proposed device based on MoSe-ZnO heterojunctions on rGO for enhanced ethanol gas sensing performances at room temperature.

In this research, we report an enhanced sensing response ethanol gas sensing device based on a ternary nanocomposite of molybdenum diselenide-zinc oxide heterojunctions decorated rGO (MoSe/ZnO/rGO) at room temperature. The sensing performance of the ternary nanocomposite sensing device has been analysed for various concentrations of ethanol gas (1-500 ppm). The gas-sensing results have revealed that for 500 ppm ethanol gas concentration, the sensing device has exhibited an enhanced response value(Rg/Ra)of 50.

Reactive oxygen species in endothelial signaling in COVID-19: Protective role of the novel peptide PIP-2.

Covert Conditioning for Persistent Aggressive Behaviors: A Case Illustration.

In psychotherapy practice and training, single case study design plays an indispensable role by effectively articulating the application of textbook knowledge, thereby bridging the gap between theory and practice. This article, on similar lines, illustrates one such successful example of the application of the classical behavioral technique of covert conditioning modified with a component of verbal challenging. A woman in her late-thirties reported with long-standing seemingly-resistant-to-treat symptoms of aggressive behavior of beating children.

OX40 agonist stimulation increases and sustains humoral and cell-mediated responses to SARS-CoV-2 protein and saRNA vaccines.

To prevent SARS-CoV-2 infections and generate long-lasting immunity, vaccines need to generate strong viral-specific B and T cell responses. Previous results from our lab and others have shown that immunizations in the presence of an OX40 agonist antibody lead to higher antibody titers and increased numbers of long-lived antigen-specific CD4 and CD8 T cells. Using a similar strategy, we explored the effect of OX40 co-stimulation in a prime and boost vaccination scheme using an adjuvanted SARS-CoV-2 spike protein vaccine in C57BL/6 mice.

Improved COVID-19 detection with chest x-ray images using deep learning.

The novel coronavirus disease, which originated in Wuhan, developed into a severe public health problem worldwide. Immense stress in the society and health department was advanced due to the multiplying numbers of COVID carriers and deaths. This stress can be lowered by performing a high-speed diagnosis for the disease, which can be a crucial stride for opposing the deadly virus.

A study of the association between Vitamin D deficiency and Dry Eye Syndrome (DES) in the Indian population.

Purpose: A study of the association between vitamin D deficiency and dry eye syndrome (DES) in the Indian population.

Methods: This was a cross-sectional, hospital-based observational study. Sixty patients diagnosed with vitamin D deficiency (<20 ng/dl) who met the inclusion criteria were sent to the Eye OPD from the Endocrinology OPD (case) were compared to 60 subjects with normal vitamin D levels (≥20 ng/dl) who attended the Eye OPD (controls).

In silico prediction, characterization and molecular docking studies on Glutathione-S-transferase as a molecular sieve for toxic agrochemicals explored in survey of North Indian farmers.

All across the globe, India is considered as an agricultural nation because its agro products drive the economy. An increase in population growth and a hike in food demands lead to the use of hazardous chemicals in farm fields. An in-depth field survey in Northern India was conducted to understand the types of agrochemicals that were used, farmers' knowledge about their safe handling, and their practices on its usage.

Polymeric and lipid nanoparticles for delivery of self-amplifying RNA vaccines.

Self-amplifying RNA (saRNA) is a next-generation vaccine platform, but like all nucleic acids, requires a delivery vehicle to promote cellular uptake and protect the saRNA from degradation. To date, delivery platforms for saRNA have included lipid nanoparticles (LNP), polyplexes and cationic nanoemulsions; of these LNP are the most clinically advanced with the recent FDA approval of COVID-19 based-modified mRNA vaccines. While the effect of RNA on vaccine immunogenicity is well studied, the role of biomaterials in saRNA vaccine effectiveness is under investigated.

Syncope as the Initial Manifestation of a Late-Stage Renal Cell Carcinoma With Metastasis to the Brain.

Renal cell carcinoma (RCC) is the most common neoplasm that arises from renal parenchyma. About one-third of patients with RCC develop metastatic spread, with common sites including the lung, liver, bone, adrenal gland, and brain. Distant metastases can be difficult to detect unless symptoms appear.

Leptomeningeal Carcinomatosis in Epithelial Ovarian Cancer: A Diagnostic Challenge.

Leptomeningeal carcinomatosis (LCM), also known as neoplastic meningitis, is a rare entity. It is generally seen in solid tumors. Ovarian cancers can infrequently cause LCM.

Pulmonary Embolism in COVID-19 and the Unanswered Questions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has ravaged the global society as we know it. As almost a dozen pharmaceutical agents go into randomized controlled clinical trials, multiple studies have surfaced trying to associate a hypercoagulable state to coronavirus disease 2019 (COVID-19) patients. We report two COVID-19 cases who presented with occlusive pulmonary embolism (PE) strongly supporting a hypercoagulable state incurred by SARS-CoV-2.

Metastatic renal cell carcinoma complicated by right atrial thrombus.

Metastasis of renal cell carcinoma to the heart is a rare event. Herein we present a case of renal cell carcinoma presenting with progressive fatigue, abdominal pain, and weight loss. Imaging studies revealed complex renal mass with extension to right atrium and histopathology confirmed the metastatic renal cell carcinoma.

Acute Pancreatitis Induced by Linagliptin: A Rare but Dangerous Side Effect.

Diabetes mellitus type 2 (DMT2) is a highly prevalent disease both in the United States and worldwide. Multiple treatment options are currently available, and several new groups of medications have been introduced over the last couple of decades. One of these groups is dipeptidyl peptidase-4 (DPP-4) inhibitors.

Understanding cartoon emotion using integrated deep neural network on large dataset.

Emotion is an instinctive or intuitive feeling as distinguished from reasoning or knowledge. It varies over time, since it is a natural instinctive state of mind deriving from one's circumstances, mood, or relationships with others. Since emotions vary over time, it is important to understand and analyze them appropriately.

Lung Adenocarcinoma Presenting as Malignant Pericardial Effusion/Tamponade.

Lung cancers are the most common primary tumors that involve the pericardium with a prevalence of up to 50%. Usually, pericardial involvement goes undetected with almost 10%-12% found among all cancer related autopsies. Rarely pericardial effusions can be the initial site of metastasis and initial manifestation of a primary tumor.
