Background: Vasoconstrictive drugs are increasingly frequently used to stop bleeding during cosmetic and reconstructive surgeries, especially subcutaneous epinephrine. As far as we are aware, no studies have been conducted on how adrenaline affects bleeding in patients having supraventricular flap surgery so we planned this study to find out the impact of various epinephrine dosages on the amount of bleeding in surgical incisions among participants undergoing supraclavicular flap surgery.

Methods: This single-blinded randomised controlled trial was performed at the Department of Plastic Surgery, Ruth Pfau Civil Hospital, from September 2022 to September 2023.

Background: Split-thickness skin grafting (STSG) is a widely employed technique for repairing wounds, such as ulcers, trauma, or in reconstructive surgeries. The objective was to compare the efficacy of different dressing materials for healing donor-site wounds after split-thickness skin grafting.

Methods: A single center, randomized controlled trial was conducted at the Department of Plastic Surgery, Civil Hospital Karachi, Pakistan, over a period of six months.

γ-Ketohydroperoxide [3-(hydroperoxy)propanal] is an important reagent in synthetic chemistry and, in particular, oxidation reactions. It is considered to be a precursor for secondary organic aerosol formation in the troposphere. Due to enhanced reactivity and limitations associated with analytical techniques, theoretical methods have been employed to study the unimolecular reactivity of hydroperoxides.

Voltage-gated sodium channels (VGSC) are transmembrane proteins that generate an action potential in excitable cells and play an essential role in neuronal signaling. Since VGSCs play a crucial role in nerve transmission they have become primary targets for a broad range of commercial insecticides. RNA interference (RNAi) is a valuable reverse genetics tool used in functional genomics, but recently, it has also shown promise as a novel agent that could be used to control agricultural insect pests.

The proton transfer reaction H + CO → HCO/HOC + H has gained considerable attention in the literature due to its importance in interstellar chemistry. The reaction products-formyl cation (HCO) and isoformyl cation (HOC)-are known to initiate multiple chemical reaction networks, resulting in complex molecules found in space. Several experimental and theoretical studies probing the structure and energetics of the [HCO] system, HCO/HOC product branching ratios, reaction mechanisms, etc.

Article Synopsis
  • The study aimed to analyze the histopathological differences in chronic hepatitis C non-responders based on their viral genotypes.
  • Conducted between 2009 and 2011, it involved 75 patients receiving liver biopsies, assessing various clinical factors and histological changes.
  • The findings revealed that genotype 3 was more common, but patients with genotype 1 showed more severe inflammation and fibrosis, while steatosis was prominently seen in genotype 3.

Objectives: To assess Ki 67 proliferative index (PI) in tissue sections, with relation to grade and clinical parameters associated with non Hodgkin's lymphoma in Pakistani population.

Methods: All cases of non Hodgkin's lymphoma, diagnosed at histopathology section of Dow Diagnostic research and reference laboratory from October 2008 to June 2010, were included for this cross sectional study. Immunohistochemical study using monoclonal antibody MIB 1, Dako, Denmark against Ki 67 antigen was carried out on paraffin embedded tissue blocks of 62 patients.

Unlabelled: Diffuse large B cell lymphoma (DLBCL) has become an emerging epidemic in recent years. Striking heterogeneity in its clinical, biological and treatment responses prompted us to identify variation in our study group. The aim was to classify the DLBCL into prognosis-based subgroups according to the WHO classification and to evaluate their relation to clinical parameters (age, gender, anatomic location and B symptoms), as well as bcl 2 and Ki 67 status.
