Article Synopsis
  • A new analytical method is being developed to accurately determine urea levels in various samples like food and clinical specimens, using a low-cost, non-enzymatic approach.
  • This method involves modifying nickel oxide nanostructures with bitter gourd peel biomass, which enhances sensitivity to urea oxidation, especially in alkaline conditions.
  • The study successfully detects urea concentrations between 1-9 mM and demonstrates the sensor's effectiveness with real samples such as milk, blood, and urine, highlighting potential applications in biomedicine and environmental protection.

Due to the rapid race of industrialization natural assets like fresh water has been deteriorated causing lethal effects in living organisms. In the current study robust and sustainable composite of in-situ antimony nanoarchitectonics in chitosan/synthesized carboxymethyl chitosan matrix were synthesized. To improve solubility, metal adsorption and water decontamination, chitosan was modified into carboxymethyl chitosan and the modification was confirmed through various characterization techniques.

Objective: To evaluate the awareness of emergency trauma management and the potential role of dentists in handling tooth avulsion injuries.

Methods: The cross-sectional study was conducted at the Dental Outpatients Department of Jinnah Medical and Dental College, Karachi, from December 2020 to March 2021, and comprised dentists and final year dental students of either gender. Data was collected using a 17-item questionnaire to assess the awareness level regarding the knowledge of traumatic dental emergencies and the role of a dentist in handling a traumatic tooth injury.

Cancer accounted for nearly 10 million deaths in 2020 and is the second leading cause of death worldwide. The chemotherapeutic agents that are in clinical practice possess a broad range of severe adverse effects towards vital organs which emphasizes the importance of the discovery of new therapeutic agents or repurposing of existing drugs for the treatment of human cancers. Pyrimethamine is an antiparasitic drug used for the treatment of malaria and toxoplasmosis with a well-documented excellent safety profile.

Article Synopsis
  • - PJM, a methanol fraction, effectively inhibits cancer cell growth by targeting the STAT3 signaling pathway, reducing the activation of upstream kinases like JAK-1/2 and c-Src while enhancing STAT3 inhibitors and key pro-apoptotic proteins.
  • - The study demonstrated that PJM reduces oncogenic protein levels, leading to decreased cell proliferation, migration, and invasion, while triggering apoptosis through the activation of caspases and down-regulation of anti-apoptotic proteins.
  • - The findings suggest that PJM's anticancer effects are closely linked to the inhibition of STAT3, with further research needed to explore its potential role in preventing cancer metastasis.

Natural compounds extracted from plants have gained immense importance in the fight against cancer cells due to their lesser toxicity and potential therapeutic effects. Raddeanin A (RA), an oleanane type triterpenoid is a major compound isolated from . As an anticancer agent, RA induces apoptosis, cell cycle arrest, inhibits invasion, migration and angiogenesis in malignant cell lines as well as in preclinical models.

Tanshinone is a herbal medicinal compound described in Chinese medicine, extracted from the roots of (Danshen). This family of compounds, including Tanshinone IIA and Tanshinone I, have shown remarkable potential as anti-cancer molecules, especially against breast, cervical, colorectal, gastric, lung, and prostate cancer cell lines, as well as leukaemia, melanoma, and hepatocellular carcinoma among others. Recent data has indicated that Tanshinones can modulate multiple molecular pathways such as PI3K/Akt, MAPK and JAK/STAT3, and exert their pharmacological effects against different malignancies.

We have investigated the protective potential of methanol extract of (IAM) on the expression of endoplasmic reticulum (ER) stress associated genes and inflammatory genes on carbon tetrachloride (CCl) induced hepatic toxicity in rats. Hepatic damage markers: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and bilirubin were elevated while the content of antioxidants: catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) and reduced glutathione (GSH) were decreased significantly ( < 0.05) in CCl treated rats as compared to the control group.

Objective: The objective of this study was to establish the diagnostic accuracy, specificity and sensitivity of fine needle aspiration cytology(FNAC) for intra-oral tumors, comparing with histopathology as the gold standard.

Materials And Methods: Forty cases of FNA cytology from intraoral tumors was performed in AFID along with the demographic data and clinical information and then diagnosed at AFIP, Rawalpindi. Then the cytology results obtained per FNAC were compared with the histopathological biopsy results of the same lesions.
