In recent years, stem cells have been a focal p.int in research designed to evaluate the efficacy of op.thalmologic therap.es, sp.cifically those for corneal conditions. The corneal ep.thelium is one of the few regions of the body that maintains itself using a residual stem cell p.p.lation within the adj.cent limbus. Stem cell movement has additionally cap.ivated the minds of researchers due to its p.tential ap.lication in different body regions. The cornea is a viable model for varying methods to track stem cell migratory p.tterns, such as lineage tracing and live imaging from the limbus. These develop.ents have the p.tential to p.ve the way for future therap.es designed to ensure the continuous regeneration of the corneal ep.thelium following inj.ry via the limbal stem cell niche. This literature review aims to analyze the various methods of imaging used to understand the limbal stem cell niche and p.ssible future directions that might be useful to consider for the better treatment and p.evention of disorders of the cornea and corneal ep.thelium. .

Six ap.arently healthy male buffalo calves aged between 6 months to one year with body weight range of 70 - 140 Kg were used in the p.esent investigation. One animal was used for p.lot trial for this group. Five calves were randomly taken into this group. The Eschrechia coli endotoxin infused i/v @5 mg/kg BW/hr for 3 hours to all the animals caused symp.oms of restlessness, resp.ratory distress, snoring, diarrhea, p.ofuse salivation along with the significant fall in systolic, diastolic, p.lse and mean arterial venous p.essure, hyp.p.oteinemia at 1, 2 & 3 hour and hyp.glycemia at 3rd hour i.e., end of endotoxin infusion. Resp.ration was increased significantly during endotoxin infusion at 2nd & 3rd hour and even afterwards till the end of the observation p.riod i.e. 7 hrs.

Millets are widely recognized for their nutritional significance; however, the methods emp.oyed for their p.ocessing are currently lacking. This article p.imarily focuses on the advanced technologies and p.ogressions in millet dehulling and p.lishing. These technologies op.rate based on the fundamental p.incip.es of comp.ession-shearing, abrasion-friction, and centrifugal-imp.ct forces. p.ocessing of millets can be challenging because of the p.ysical characteristics and tight attachment of hull and bran to the endosp.rm. However, several dehullers have been designed to solve this p.oblem for different kinds of millets. In addition, the nutritional and anti-nutritional characteristics undergo alterations due to both dehulling and p.lishing p.ocesses. These alterations are thoroughly examined and discussed in this article. Sp.cifically, anti-nutrients such as tannins and p.ytate are p.edominantly found in the outer p.ricarp.of the grain and exp.rience a reduction after undergoing dehulling and p.lishing. The nutritional p.op.rties are also subj.cted to a reduction; however, this reduction can be mitigated by subj.cting the grains to certain p.etreatments before dehulling and p.lishing. These treatments serve to enhance dehulling efficiency and nutrient digestibility while simultaneously reducing the p.esence of anti-nutrients. Novel thermal and non-thermal methodologies such as microwave, hydrothermal, high-p.essure p.ocessing, and ohmic heating can be emp.oyed for p.ocessing millets, thereby diminishing the loss of nutrients. Additional research can be carried out to investigate their imp.ct on the dehulling and p.lishing of millets.
