A continuous and dependable energy supply is essential for maintaining a nation's economic stability. Globally, coal ranks as the second largest fossil fuel resource after oil and gas, leading to the establishment of coal-fired power infrastructure. Nonetheless, the pyrolysis and "burn-out" reactions of High-ash coal impose fundamental limitations that hinder its efficient use and exacerbate environmental degradation.

Objective: To evaluate the effect of marijuana use compared to cigarette smoking on imaging findings in the lungs.

Methods: By searching the electronic medical record, we identified patients who were marijuana users who never smoked; current smokers; and non-marijuana never smokers, who underwent chest CT in our healthcare system in 2019. We generated a random sample of 100 marijuana users as well as 100 each age- and sex-matched controls from the current smoker and never-smoker groups.

With refinements in electromagnetics, diverse medical applications have evolved to detect diseases efficaciously. Breast cancer, a dominant cause of mortality among women worldwide, necessitates early diagnosis and screening for timely medical intervention. This research establishes the design, simulation, and analysis of an advanced triangular slotted circular flexible Ultra-wideband (UWB) antenna optimized for breast cancer detection and healthcare monitoring.

Plants alternate between diploid sporophyte and haploid gametophyte generations. In mosses, which retain features of ancestral land plants, the gametophyte is dominant and has an independent existence. However, in flowering plants the gametophyte has undergone evolutionary reduction to just a few cells enclosed within the sporophyte.

Objective: To assess adherence to ACR recommendations for managing incidental adrenal lesions detected on lung cancer screening (LCS) CT examinations.

Methods: We performed a retrospective analysis of all LCS CT examinations within our health care system from January 2015 to August 2023. We included CTs that were reported with Lung-RADS "S" modifier for a focal adrenal lesion.

Background & Objective: Breast cancer is the leading cause of cancer deaths among women worldwide. Fine needle aspiration cytology (FNAC) and breast sonography have played a pivotal role in the characterization of a breast lump. The main objective of this study was to analyze the correlation between the International Academy of Cytology (IAC) Yokohama for Reporting Breast Fine Needle Aspiration Biopsies (FNAB) and breast imaging reporting and data system (BIRADS) for sonography along with histopathological correlation.

Background: Endophytic fungi represent a compelling assemblage of microorganisms that inhabit plant tissues without inflicting any discernible detriment to the host organism. They foster a symbiotic association with their host plants, frequently conferring advantages such as augmented growth, enhanced resilience to stressors, and safeguarding against pathogens.

Quorum sensing (QS) also known as bacterial cell-cell communication or bacterial crosstalk is a phenomenon regulating various bacterial traits that can affect plant growth and defence. Similarities in the structure of root exudates and bacterial signalling molecules have tremendous implications governing the plant heath. The rhizosphere ecosystem being an excellent example of plant-microbe and microbe-microbe interactions harbours a variety of microorganisms exhibiting quorum sensing.

While immunotherapy shows great promise in patients with triple negative breast cancer, many will not respond to treatment. Radiotherapy has the potential to prime the tumor-immune microenvironment for immunotherapy. However, predicting response is difficult due to tumor heterogeneity across patients, which necessitates personalized medicine strategies that incorporate tumor tracking into the therapeutic approach.

Article Synopsis
  • Trauma and accidental injuries are a major global health concern, with India experiencing the highest road accident deaths, accounting for 11% of the world's total.
  • A study from January 2023 to January 2024 analyzed wound samples from road traffic accident (RTA) patients in a northern Indian tertiary care center to assess bacterial contamination and antibiotic susceptibility.
  • Out of 189 samples, 52.38% showed microbial growth, predominantly Gram-negative bacilli, with none being resistant to colistin; 26.45% of patients developed sepsis, linked to raised procalcitonin levels and low Glasgow Coma Scale scores.

Article Synopsis
  • The study evaluates how effectively CT and PET/CT imaging can distinguish between cardiac sarcoma and cardiac hematologic neoplasms, both rare but serious cardiac cancers.
  • Researchers reviewed cases from 69 patients, finding differences in age, with sarcoma patients being younger, and noted that hematologic malignancies had more AV groove involvement and RCA encasement.
  • Despite overlapping features, using AV groove involvement and patient age, a decision tree could predict the diagnosis with 75% accuracy, reinforcing that biopsy is essential for definitive diagnosis.

Recalcitrant chemicals in the environment not only present obstacles to living organisms but also contribute to the degradation of natural resources. One contribution to environmental pollution is the discharge of synthetic dyes from the textile sector. This study investigates the combined effect of microbial cells and biochar on eliminating methyl orange (MO) dye.

Aim And Objective: The aim of the present study was to quantitatively assess the apoptotic index at a light microscopic level in hyperkeratosis with varying histological degrees of dysplasia and different grades of oral squamous cell carcinoma (OSCC) and its correlation with prognostic significance.

Study Design: The study included the histo-pathologically diagnosed cases of hyperkeratosis with varying degrees of dysplasia and different grades of OSCC, which were retrieved from the archives of the department, and clinical details were retrieved from the case records of the patients. The sample size consisted of 80 biopsied cases, divided into seven groups of 10 experimental cases and one group of 10 cases of normal mucosa as a control group.

Focused ultrasound (FUS) is a non-invasive and non-ionizing technique which deploys ultrasound waves to induce bio-effects. When paired with acoustically active particles such as microbubbles (MBs), it can open the blood brain barrier (BBB) to facilitate drug delivery otherwise inhibited due to the presence of BBB. One of the parameters that affects the FUS beam propagation is the beam incidence angle on the skull.

Ovarian tumors are a common form of neoplasia in women and it accounts for about 30% of female genital cancers. A coexistence of ovarian tumors with the same histogenetic origin such as germ cell or epithelial or sex cord stromal, but different histologic subtype is relatively common, whereas a synchronous occurrence of tumors with different histogenetic origin is rare. We report a case of 58-year-old woman with the synchronous presentation of adult granulosa cell tumor with fibroma (ovarian tumors with the same origin (sex cord stromal) but different histologic type) in one ovary and Brenner tumor (epithelial origin) in other ovary.
