Background: Antimicrobial resistance (AMR) is a global threat driven mainly by horizontal gene transfer (HGT) mechanisms through mobile genetic elements (MGEs) including integrons. The variable region (VR) of an integron can acquire or excise gene cassettes (GCs) that confer resistance to antibiotics based on the selection pressure. Escherichia coli plays a significant role in the genetic transfer of resistance determinants to other Gram-negative bacteria. Current study is aimed to detect and compare integron-mediated resistance in clinical isolates of E. coli. Unique isolates of E. coli from urine or blood cultures were studied for their antimicrobial resistance patterns and integrons were …

Influence Of Physical And Material Parameters On Switching Current Density In Perpendicular Stt-Mtj: A Micromagnetic Study, Abhishree Shaw, Vinod Kumar Joshi

Open Access archive

Switching in magnetic tunnel junctions (MTJs) is considered to be coherent according to the macrospin model but above a critical characteristic length (Rc) this process becomes incoherent. As a result, switching becomes a complex process and affects the switching current density (Jc). We designed a spin transfer torque (STT) based single barrier perpendicular MTJ (SMTJ) and observed the influence of the junction size and exchange stiffness constant (Aex) on the switching process through micromagnetic simulations performed on Object Oriented Micromagnetic Framework (OOMMF). It was found that coherent switching occurred only for junction diameter ≤20nm and showed dependence on Aex as …

Background: Though rare, benign lesions that usually do not necessitate active intervention, osteomas of the external auditory canal, can be troublesome when they start to produce mass effect and severe obstruction to the external auditory canal. Even more insidious is the rarer phenomenon of canal wall cholesteatomas, which have been known to cause significant canal erosion and if left unchecked and spontaneous destruction of the adjacent anatomical structures, including the facial nerve, temporomandibular joint, sigmoid sinus, and skull base. The occurrence of both these exceptionally uncommon findings in the same canal is an unusual finding and may point to an …

Metformin Alleviates Reactive Gliosis And Neurodegeneration, Improving Cognitive Deficit In A Rat Model Of Temporal Lobe Epilepsy, Sree Lalitha Bojja, Shashi Anand, Ranjana W. Minz, Bikash Medhi

Open Access archive

Cognitive impairment is a prevalent co-morbidity associated with epilepsy. Emerging studies indicate that neuroinflammation could be a possible link between epilepsy and its comorbidities, including cognitive impairment. In this context, the roles of glial activation, proinflammatory mediators, and neuronal death have been well studied and correlated with epilepsy-associated cognitive impairment in animal studies. While recent reports have demonstrated the anti-epileptogenic and anti-convulsant actions of metformin, its effect on epilepsy associated cognitive deficit remains unknown. Therefore, the current study investigated the effect of metformin treatment on neuroinflammation, neurodegeneration, and cognitive deficits after inducing status epilepticus (SE) with lithium-pilocarpine in rats. Metformin …
