EFFECT OF STORAGE TEMPERATURES ON THE QUALITY OF PINK PERCH SURIMI

ABSTRACT A detailed investigation on microbiological, biochemical and organoleptic quality changes in frozen surimi of pink perch (Nemipterus japonicus) stored at ambient (25±5°C), refrigerated (5±3 °C) and at frozen temperatures (-10±2 °C), was carried out. Bacterial count, trimethylamine and total volatile nitrogen values increased with storage time while, organoleptic score decreased. Nutrient contents and gel strength of surimi decreased while, moisture and whiteness increased with storage period. Results indicated that at ambient temperature, frozen surimi can be stored only for about 8 hrs, while at refrigerator temperature up to 5 days and at frozen temperature up to 60 days.     Keywords: Pink pearch, minced meat, surimi, frozen storage.

Molecular mechanisms of cell death: recommendations of the Nomenclature Committee on Cell Death 2018.

Over the past decade, the Nomenclature Committee on Cell Death (NCCD) has formulated guidelines for the definition and interpretation of cell death from morphological, biochemical, and functional perspectives. Since the field continues to expand and novel mechanisms that orchestrate multiple cell death pathways are unveiled, we propose an updated classification of cell death subroutines focusing on mechanistic and essential (as opposed to correlative and dispensable) aspects of the process. As we provide molecularly oriented definitions of terms including intrinsic apoptosis, extrinsic apoptosis, mitochondrial permeability transition (MPT)-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, entotic cell death, NETotic cell death, lysosome-dependent cell death, autophagy-dependent cell death, immunogenic cell death, cellular senescence, and mitotic catastrophe, we discuss the utility of neologisms that refer to highly specialized instances of these processes. The mission of the NCCD is to provide a widely accepted nomenclature on cell death in support of the continued development of the field

Valorisation of Biowastes for the Production of Green Materials Using Chemical Methods

With crude oil reserves dwindling, the hunt for a sustainable alternative feedstock for fuels and materials for our society continues to expand. The biorefinery concept has enjoyed both a surge in popularity and also vocal opposition to the idea of diverting food-grade land and crops for this purpose. The idea of using the inevitable wastes arising from biomass processing, particularly farming and food production, is, therefore, gaining more attention as the feedstock for the biorefinery. For the three main components of biomass—carbohydrates, lipids, and proteins—there are long-established processes for using some of these by-products. However, the recent advances in chemical technologies are expanding both the feedstocks available for processing and the products that be obtained. Herein, this review presents some of the more recent developments in processing these molecules for green materials, as well as case studies that bring these technologies and materials together into final products for applied usage

Prevalence and risk factors for early chronic allograft nephropathy in a live related renal transplant program

Background: Chronic allograft nephropathy (CAN) is a common cause of delayed allograft failure throughout the world. Its prevalence and risk factors vary depending on a number of factors. There is little information on the prevalence and risk factors for early CAN in live related renal transplant patients. Objectives: We aimed to determine the prevalence and the risk factors of early CAN in our setup. Patients and Methods: The study was conducted at Sindh Institute of Urology & Transplantation (SIUT), Karachi, from 2002 to 2005 on patients who had live related kidney transplantation and underwent at least one allograft biopsy within 18 months of transplantation. The biopsies were performed and prepared in accordance with established indications and guidelines. The Banff 97 classification and its updates were used to diagnose and categorize the biopsy pathology. Patients were divided into two groups depending on the presence or absence of CAN on biopsies. Following parameters were compared among the groups: age, sex, human leukocyte antigen (HLA) match, immunosuppression used, acute rejection (AR) episodes, urinary tract infections (UTIs), viral infections, cyclosporine levels, early and late graft function monitored by serum creatinine. Results: A total of 164 patients fulfilled the study inclusion criteria. The mean age of recipients and donors was relatively young. The majority of the donors were siblings. The overall prevalence of CAN was 25.6% (42/164), between 3 and 18 months post transplantation. The median time to the appearance of CAN was 9 months post-transplant. The prevalence of CAN increased as post-transplant duration increased. In 39 (92.8%) subjects, CAN was detected on the second or subsequent graft biopsy. Only 3 (7.2%) patients showed CAN on the first graft biopsy. The majority of cases belonged to moderate degree or grade II CAN. The mean serum creatinine values were higher in the CAN group at the time of discharge and all times post-transplantation. Conclusions: In conclusion, the results show that serum creatinine at the time of discharge is a useful predictor of later development of chronic changes in the allograft. Further studies are needed to identify the risk factors for the early development of chronic changes in living related renal transplant program

Language Nesting, Superdiversity and African Diasporas in Regional Australia

This paper tells previously untold stories about the dynamic cultures, linguistic repertoires and language practices of migrants and refugees that are continuously shaped and mediated by the convoluted histories, journeys and migration itineraries of these people. It brings to light the effect of proficiency in multiple languages on their speakers' affiliations, and their perceptions of belonging in local communities. The paper draws on the outcomes of a study with refugee background Africans (hereafter, African diasporas) in regional New South Wales (NSW) to propose the language nesting model that seeks to illustrate the complex linguistic and discursive practices of these people and how such resources are used to create and negotiate material and social spaces in everyday life. The paper concludes that the stories that were elicited - about the languages, cultures, identities, migration histories and just about everything else about the sampled African diasporas - both support and resist the theoretical suppositions of superdiversity in equal measure
