Background Anemia is characterized by a lower red blood cell (RBC) count than the usual rate or the average count that should be found in the blood. It is described by the reduction in the concentration of hemoglobin, the number of RBCs, and the O2-carrying capacity of the blood. A complete blood count (CBC) gives serious information on changes in the size and shape of RBCs and an indication of inclusion bodies that will help exclude anemia.

Gastrointestinal malignancies, most specifically duodenal malignancy, are uncommon in the population; however, they are tricky to manage because the lesions are diagnosed at a late stage and located in a complex area. This case report focuses on a patient who was diagnosed with a second (descending) part of the duodenum (D2) malignancy; the tumour was localised at the second part of the duodenum, and the management of this patient was through the Whipple procedure or pancreaticoduodenectomy. The patient complained of stinging abdomen pain.

Article Synopsis
  • This study investigates serious eye problems that can occur after dengue fever, highlighting the importance of recognizing these complications for timely treatment.
  • Conducted in Uttar Pradesh between October and November 2023, the research analyzed 13 patients, primarily middle-aged men, some with existing health issues like diabetes and hypertension.
  • The study found various severe ocular conditions resulted from dengue, with diminished vision being the most common symptom, indicating a crucial need for early detection and public awareness to prevent permanent vision loss.

Small-cell lung cancer (SCLC) is the most fatal form of lung cancer. Intratumoral heterogeneity, marked by neuroendocrine (NE) and non-neuroendocrine (non-NE) cell states, defines SCLC, but the cell-extrinsic drivers of SCLC plasticity are poorly understood. To map the landscape of SCLC tumor microenvironment (TME), we apply spatially resolved transcriptomics and quantitative mass spectrometry-based proteomics to metastatic SCLC tumors obtained via rapid autopsy.

Article Synopsis
  • - The study aimed to explore pharmacogenomics related to the calicheamicin pathway to find predictive markers for how patients with acute myeloid leukemia (AML) respond to gemtuzumab ozogamicin (GO) treatment.
  • - Researchers analyzed genetic variations, specifically single nucleotide polymorphisms (SNPs), in genes involved in DNA-damage response, and discovered that a specific score (DDR_PGx7) could predict patient outcomes, showing significant differences in event-free survival and overall survival for patients receiving GO.
  • - The findings suggest that the DDR_PGx7 score could help customize GO treatment for AML patients, but further research is needed to confirm these results in larger and different patient groups.

Gene expression control based on clustered regularly interspaced short palindromic repeats (CRISPR) has emerged as a powerful approach for constructing synthetic gene circuits. While the use of CRISPR interference (CRISPRi) is already well-established in prokaryotic circuits, CRISPR activation (CRISPRa) is less mature, and a combination of the two in the same circuits is only just emerging. Here, we report that combining CRISPRi with SoxS-based CRISPRa in can lead to context-dependent effects due to different affinities in the formation of CRISPRa and CRISPRi complexes, resulting in loss of predictable behavior.

() is one of the major causes of death worldwide and there is a pressing need for the development of novel drug leads. The Imidazole Glycerol Phosphate Dehydratase (IGPD) of is one of the key enzymes in the histidine biosynthesis pathway and has been recognized as the potentially underexploited drug target for anti-tuberculosis treatment. In the present study, 6063 structurally diverse plant secondary metabolites (PSM) were screened for their efficiency in inhibiting the catalytic activity of IGPD through molecular docking.

Purpose: To evaluate the effectiveness of amblyopia treatment through a smartphone-based anaglyph system by virtual reality (VR) in adult patients.

Methods: A total of 10 subjects diagnosed with anisometropic amblyopia were enrolled during the study period. Best Corrected Visual Acuity (BCVA), stereoacuity, and contrast acuity were evaluated during three visits (at presentation, 3 months and 6 months) of smartphone-based anaglyph video run in the VR mode.

Introduction: The emergence of SARS-CoV-2, which causes COVID-19, has led to over 400 million reported cases worldwide. COVID-19 disease ranges from asymptomatic infection to severe disease and may be impacted by individual immune differences.

Methods: We used multiparameter flow cytometry to compare CD4+ and CD8+ T cell responses in severe (ICU admitted) and non-severe (admitted to observational unit) hospitalized COVID-19 patients.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease (COVID-19) in humans, with symptoms ranging from mild to severe, including fatality. The molecular mechanisms surrounding the effects of viral infection on the host RNA machinery remain poorly characterized. We used a comparative transcriptomics approach to investigate the effects of SARS-CoV-2 infection on the host mRNA and sRNA expression machinery in a human lung epithelial cell line (Calu-3) and an African green monkey kidney cell line (Vero-E6).

Background The Covid-19 pandemic and subsequent lockdown in India caused disruptions in cancer treatment due to the restriction on movement of patients. We aimed to maintain continuity in cancer treatment during the lockdown through teleconsultations. We tried to reach out to our patients using telephonic consultations by establishing a Teleconsult Centre facility run by a team of doctors and patient navigators.

Monkeypox virus (MPXV) is an orthopoxvirus in the Poxviridae family. The current multinational monkeypox outbreak has now spread to 96 countries that have not historically reported monkeypox, with most cases occurring among gay, bisexual, and other men who have sex with men (1,2). The first monkeypox case in the United States associated with this outbreak was identified in May 2022 in Massachusetts (1); monkeypox has now been reported in all 50 states, the District of Columbia (DC), and one U.
