The Ganga river, one of the largest and most culturally significant rivers in India, supports millions of people living along its banks. However, extensive use and untreated wastewater discharge have led to significant contamination. This study utilizes land use and land cover (LULC) analysis, along with regular water sampling from 2021 to 2222, to assess variations in physical, chemical, and biological characteristics and evaluate health risks posed by heavy metals across eight monitoring sites in the Ganga and Yamuna rivers, Prayagraj, India.

Introduction: Mucoid degeneration of the cruciate ligament is a well-known entity, but symptomatic lesions are rare. It is even rarer to find symptomatic posterior cruciate ligament mucoid degeneration than the anterior cruciate ligament.

Case Report: A 63-year-old male presented to our hospital complaining of posterior knee pain was induced when the knee approached full flexion without episodes of trauma, despite conservative treatment over the preceding 8 months, his symptoms persisted.

Introduction: Osteonecrosis of femoral head (ONFH) is a disabling condition of the hip joint with multifactorial etiology and is associated with genetic predilection and exposure to certain risk factors most commonly being chronic alcohol or steroid intake. Total hip arthroplasty (THA) remains the gold standard for end-stage femoral head osteonecrosis. The outcome after the surgery is mainly affected by age, activity levels and other factors that affect the development of ONFH.

Ovarian cancer, often referred to as the "silent killer," is notoriously difficult to detect in its early stages, leading to a poor prognosis for many patients. Diagnosis is often delayed until the cancer has advanced, primarily due to its ambiguous and frequently occurring clinical symptoms. Ovarian cancer leads to more deaths than any other cancer of the female reproductive system.

Article Synopsis
  • * The study focuses on a porous single-atom catalyst (pCo-NC) made of a cobalt atom coordinated with nitrogen in a graphene structure, showing ORR activity comparable to traditional catalysts like Pt/C.
  • * The catalyst's performance varies significantly in acidic (HClO) versus alkaline (KOH) environments, with the differences linked to protonation effects and electron transfer limitations at the electrode interface, and results are validated through advanced simulation methods.

  • Ayurveda suggests that each person has a unique entity that affects their physical, physiological, and psychological traits, influencing their reactions to stimuli beyond just genetics.
  • This research seeks to validate this Ayurvedic concept by exploring the KCNJ11 gene's role in type 2 diabetes susceptibility through an analysis of patient and control groups.
  • The study found that specific protein mutations were linked to diabetes in particular groups, indicating that variations in amino acids can impact protein function and contribute to the development of the disease.

  • - The study investigates how trace elements (like zinc and magnesium) relate to inflammation markers (TNF-α and IL-6) in children with short stature, aiming to identify potential causes for this condition.
  • - Researchers analyzed 220 samples, revealing lower levels of zinc and magnesium and higher copper levels in short-statured individuals, with a notable correlation between these trace elements and inflammation markers.
  • - The findings suggest that monitoring the Cu/Zn ratio and inflammation markers could help identify children at risk for short stature, and zinc supplementation might improve growth by reducing inflammation.

Seasonal variations directly impact the biochemical and microbial properties of the soil, influence carbon and nutrient cycling within the soil system. Soils under tree plantation (TP) are rich in organic matter and microbial population, making them more susceptible to seasonal variation. We studied the effect of seasonal variations in soil chemical properties (pH, electrical conductivity (EC), total organic carbon (TOC), total nitrogen (TN), C/N ratio etc) and microclimate (moisture and temperature) on microbial respiration (SR), biomass, and carbon (C) utilization efficiency under 13 years old Kadamb ( Miq.
