Need for a balance between short food supply chains and integrated food processing sectors: COVID-19 takeaways from India.

India is an agrarian country with a long history of traditional food processing practices and Short food supply chains (SFSC). However, last few decades saw a huge investment and steady increase in large scale integrated food processing units to combat globalization, food security and India's export demands. Recent outbreak of COVID-19 has manifested the drawbacks in the existing production and supply chain system with a wide range of issues and enforces the need for a more balanced approach.

Optimized conditions for a quantitative SELDI TOF MS protein assay.

The development of peptide/protein analyte assays for the purpose of diagnostic tests is driven by multiple factors, including sample availability, required throughput, and quantitative reproducibility. Laser Desorption/ionization mass spectrometry methods (LDI-MS) are particularly well suited for both peptide and protein characterization, and combining chromatographic surfaces directly onto the MS probe in the form of surface enhanced laser desorption/ionization (SELDI)-biochips has improved the reproducibility of analyte detection and provided effective relative quantitation. Here, we provide methods for developing reproducible SELDI-based assays by providing a complex artificial protein matrix background within the sample to be analyzed that allows for a common and reproducible ionization background as well as internal normalization standards.

Internal jugular phlebectasia as an incidental finding in cervical spine surgery.

Idiopathic internal jugular phlebectasia, occurs either unilaterally or bilaterally affecting the internal jugular vein is a rare congenital variation often diagnosed during childhood. It usually presents with a benign swelling over the lateral side of neck on the affected side, seen on exertion. A-30-year old male was operated for anterior cervical dissectomy from right lateral approach and was diagnosed per-operatively as internal jugular phlebectasia.

Reducing protein concentration range of biological samples using solid-phase ligand libraries.

The discovery of specific polypeptides of diagnostic relevance from a biological liquid is complicated by the overall vast number and the large concentration range of all polypeptides/proteins in the sample. Depletion or fractionation methodologies have been used for selectively removing abundant proteins; however, they failed to significantly enrich trace proteins. Here we expand upon a new method that allows the reduction of the protein concentration range within a complex mixture, like neat serum, through the simultaneous dilution of high abundance proteins and the concentration of low abundance ones in a single, simple step.

Reduction of the concentration difference of proteins in biological liquids using a library of combinatorial ligands.

The discovery of polypeptides and proteins with relevance to a particular biological state is complicated by their vast number and concentration range in most biological mixtures. Depletion methodologies are frequently used to remove the most abundant species; however, this removal not only fails significantly to enrich trace proteins, it may also nonspecifically deplete them due to their interactions with the removed high-abundance proteins. Here we report a simple-to-use methodology that reduces the protein concentration range of a complex mixture like whole serum through the simultaneous dilution of high-abundance proteins and the concentration of low-abundance proteins.
