Article Synopsis
  • The study examined the presence of antibiotic residues in milk from five farms in Keraniganj, Dhaka, focusing on commonly used antibiotics like oxytetracycline and fluoroquinolones.
  • Using a reliable RP-HPLC method, the study found that oxytetracycline was present in 90% of milk samples, with levofloxacin (66%), enrofloxacin (64%), and ciprofloxacin (62%) also detected.
  • While 30% of oxytetracycline-positive samples exceeded the maximum residue limits (MRL), no samples exceeded the MRL for the other antibiotics, indicating low human health risks, though children might be more vulnerable to prolonged

Nanomaterials show great promise for cancer treatment. Nonetheless, most nanomaterials lack selectivity for cancer cells, damaging healthy ones. Cerium dioxide (ceria, CeO) nanoparticles have been shown to exert selective toxicity toward cancer cells due to the redox modulating properties they display as their size decreases.

Diabetic bone disease (DBD) is a frequent complication in patients with type 2 diabetes mellitus (T2DM), characterised by altered bone mineral density (BMD) and bone turnover marker (BTMs) levels. The impact of different anti-diabetic medications on the skeleton remains unclear, and studies have reported conflicting results; thus, the need for a comprehensive systematic review is of paramount importance. A systematic search was conducted in PubMed and the Cochrane Library.

  • Total hip arthroplasty (THA) is often used to treat hip issues; however, patients with ochronotic arthropathy face higher risks of complications due to poor bone health.
  • A case study documented a 52-year-old man with this condition who successfully underwent bilateral THA using a dual mobility cup (DMC) to address significant joint problems.
  • The study concluded that using a DMC in THA can improve stability and motion, lowering the chance of dislocation and implant failure in patients with ochronotic arthropathy.

The glycosides of two flavonoids, naringin and naringenin, are found in various citrus fruits, bergamots, tomatoes, and other fruits. These phytochemicals are associated with multiple biological functions, including neuroprotective, antioxidant, anticancer, antiviral, antibacterial, anti-inflammatory, antiadipogenic, and cardioprotective effects. The higher glutathione/oxidized glutathione ratio in 3-NP-induced rats is attributed to the ability of naringin to reduce hydroxyl radical, hydroperoxide, and nitrite.

Pectin is an acidic heteropolysaccharide found in the cell walls and the primary and middle lamella of land plants. To be authorized as a food additive, industrial pectins must meet strict guidelines set forth by the Food and Agricultural Organization and must contain at least 65% polygalacturonic acid to achieve the E440 level. Fruit pectin derived from oranges or apples is commonly used in the food industry to gel or thicken foods and to stabilize acid-based milk beverages.

Introduction: Superbugs are microorganisms that cause disease and have increased resistance to the treatments typically used against infections. Recently, antibiotic resistance development has been more rapid than the pace at which antibiotics are manufactured, leading to refractory infections. Scientists are concerned that a particularly virulent and lethal 'superbug' will one day join the ranks of existing bacteria that cause incurable diseases, resulting in a global health disaster on the scale of the Black Death.

Abnormalities in the mitogen-activated protein kinase (MAPK) signaling pathway are a key contributor to the carcinogenesis process and have therefore been implicated in several aspects of tumorigenesis, including cell differentiation, proliferation, invasion, angiogenesis, apoptosis, and metastasis. This pathway offers multiple molecular targets that may be modulated for anticancer activity and is of great interest for several malignancies. Polyphenols from various dietary sources have been observed to interfere with certain aspects of this pathway and consequently play a substantial role in the development and progression of cancer by suppressing cell growth, inactivating carcinogens, blocking angiogenesis, causing cell death, and changing immunity.
