Antimicrobial peptides (AMPs) are small, positively charged biomolecules produced by various organisms such as animals, microbes, and plants. These AMPs play a significant role in defense mechanisms and protect from adverse conditions. The emerging problem of drug resistance in microbes poses a global health challenge in treating diseases.

Article Synopsis
  • The study investigates immune-related adverse events (irAEs) in patients with high-risk early triple-negative breast cancer (TNBC) who were treated with pembrolizumab alongside chemotherapy.
  • Out of 233 patients evaluated, 34% experienced irAEs, primarily endocrinopathies and gastrointestinal issues, with some leading to severe complications requiring hospitalization or treatment adjustments.
  • The findings highlight the prevalence of these adverse events in a real-world setting and underscore the importance of monitoring long-term effects as pembrolizumab becomes more commonly used in early TNBC treatment.

Objectives: The study aimed to analyze the impact of aphasia on quality of life (QoL) in persons with ischemic stroke per radiological severity, compare equally severe but nonaphasic stroke survivors, and analyze the impact of hyperbaric oxygen therapy (HBOT) exposure Methods: Patients with first-ever middle cerebral artery (MCA) stroke were categorized by radiological severity into high, intermediate, and low Alberta Stroke Program Early CT Score (ASPECTS). The Stroke Aphasia Quality of Life (SAQoL) Scale was used for outcome analysis. Inclusion criteria were age 40-65, 12-16 months after stroke, MCA distribution, first stroke, and ischemic stroke.

Article Synopsis
  • Synthetic hematite nanoparticles are widely researched for various applications, but natural iron nanoparticles in freshwater ecosystems have been under-studied.
  • A study in southern India identified natural iron nanoparticles in tropical freshwater, characterized by advanced techniques showing they exist as mesoporous, amorphous hematite microspheres.
  • The presence of Bacillus cereus indicates a biogeochemical origin, enhancing understanding of these nanoparticles' ecological roles and suggesting their potential for industrial uses.

Myositis induced by immune checkpoint inhibitors (ICIs) is an infrequent, potentially fatal, immune-related adverse event. It has higher incidence in patients who receive combination ICI therapy compared to monotherapy. Patients can present with clinical manifestation symptoms of myositis alone or in combination with myocarditis and/or myasthenia gravis, which significantly worsens the course and prognosis.

This study focuses on the improvement of bioremediation of textile dye Reactive Red 195 using agro-industrial waste, groundnut oil cake (GNOC) obtained after oil-pressing. The treatment of GNOC with 1 N HSO had resulted in physiochemical changes on the insoluble porous adsorbent, which improved their adsorption efficiency. The dye removal efficiency increased from 55% to 94% on acidification of GNOC.

Lupus enteritis (LE) is a rare presentation of systemic lupus erythematosus manifesting with nonspecific symptoms, laboratory derangements, and imaging findings. Rarely, LE may progress to bowel perforation, hemorrhage, and even death. Treatment with systemic glucocorticoids often results in rapid clinical improvement, but patients may require further immunosuppression.

Background: Bone-targeted therapy (BTT) including zoledronic acid (ZA) and denosumab decreases the risk of skeletal-related events (SREs) in patients with metastatic breast cancer (MBC) and bone metastasis. The impacts from prolonged BTT on SREs and BTT-associated harms are unknown and are becoming important to understand as these patients survive for longer periods.

Methods And Materials: We conducted a retrospective study of 224 patients with MBC and bone metastasis who survived for more than 2 years after diagnosis and received treatment at our institution between 2016 and 2021.

The anterior hypothalamic area (AHA) is a critical structure for defensive responding. Here, we identified a cluster of parvalbumin-expressing neurons in the AHA (AHA) that are glutamatergic with fast-spiking properties and send axonal projections to the dorsal premammillary nucleus (PMD). Using in vivo functional imaging, optogenetics, and behavioral assays, we determined the role of these AHA neurons in regulating behaviors essential for survival.

Auditory brainstem implantation (ABI) is a viable option for individuals with inner ear anomalies, or other retro-cochlear pathologies, where cochlear implantation is not a suitable option. Although ABI has its advantages in those populations, most often, ABI is not recommended or accepted by the patients because of its limitations and shortcoming such as open-set word recognition in auditory mode, limited infrastructures for carrying out ABI surgery, and the high cost of implantation. This review highlights the benefits in non-tumor patients with ABI surgery and possible reasons for the limited acceptance of the ABI device from an Indian perspective.

Dysregulation of body weight maintenance and opioid dependence are often treated as independent disorders. Here, we assessed the effects of both acute and long-term administration of morphine with and without chemogenetic activation of agouti-related peptide (AGRP)-expressing neurons in the arcuate nucleus (ARC neurons) to elucidate whether morphine and neuronal activation affect feeding behavior and body weight. First, we characterized interactions of opioids and energy deficit in wild-type mice.

Lung cancer is the prime cause of cancer-related deaths globally, with a contribution of 85% from non-small cell lung cancer. Before a few decades back, conventional chemotherapy was the most chosen treatment option for NSCLC but with side effects. Now, the treatment approaches have shifted to a new trend, targeted therapy, and a better treatment strategy with minimal side effects compared to chemotherapy.

Background: Meningococcal disease is a life-threatening illness that can cause sequelae such as neurological impairment, hearing loss, seizures, limb amputations, and scarring. Adolescents and young adults are at highest risk for contracting this disease which comes with a case-fatality ratio of 10-15%. Common serogroups in the United States are B, C, W, and Y, which are covered by two separate vaccines administered in a two-dose series.
