Apoptosis, or programmed cell death, is a well-ordered process that allows damaged or diseased cells to be removed from an organism without severe inflammatory reactions. Multiple factors, including microbial infection, can induce programmed death and trigger reactions in both host and microbial cellular pathways. Whereas an ultimate outcome is host cell death, these apoptotic triggering mechan...

TOPIC Attachment theory and reactive attachment disorder (RAD). PURPOSE To highlight current perspectives on attachment theory, RAD, and treatment implications using a case study of an 8-year-old patient with RAD. SOURCES Selected multidisciplinary literature related to attachment theory and RAD. CONCLUSIONS The literature provides a body of work that substantiates the importance of early...

Typically developing adults and children can rapidly reach consensus regarding the trustworthiness of unfamiliar faces. Maltreated children can have problems with trusting others, yet those with the disinhibited form of reactive attachment disorder (dRAD) can be indiscriminately friendly. Whether children with dRAD symptoms appraise and conform to typical judgements about trustworthiness of fac...

Dear Referee, we are very thankful for your comments. Below you will find our answers on them. In attachment, there is the revised manuscript where changes are tracked by red color. The language is readable and clear, but does contain occasional errors that a native speaker could correct. The manuscript was checked by a native speaker Although part of the study is somewhat descriptive and could...

Bacterial adhesion is an important step in tissue colonization and depends extensively on the surface properties of a bacterial cell. For many microorganisms the prerequisite for host body occupancy is a break in tissue continuity. The next step is ongoing tissue destruction by products of bacterial metabolism: microbial enzymes and toxins. This happens, for example, in the initial phase of per...

Extensive use of indwelling devices in modern medicine has revoked higher incidence of device associated infections and most of these devices provide an ideal surface for microbial attachment to form strong biofilms. These obnoxious biofilms are responsible for persistent infections, longer hospitalization and high mortality rate. Gene regulations in bacteria play a significant role in survival...

It is critical for bacteria to recognize surface contact and initiate physiological changes required for surface-associated lifestyles. Ubiquitous microbial appendages called pili are involved in sensing surfaces and facilitating downstream behaviors, but the mechanism by which pili mediate surface sensing has been unclear. We visualized Caulobacter crescentus pili undergoing dynamic cycles of ...

We consider a mathematical model for a bacterial population in a continuously stirred tank reactor (CSTR) with wall attachment. This is a modification of the Freter model, in which we model the sessile bacteria as a microbial biofilm. Our analysis indicates that the results of the algebraically simpler original Freter model largely carry over. In a computational simulation study, we find that t...

Immobilization technology creates exciting new opportunities for commercial development in a wide range of industries. There are several reasons for using an enzyme in an immobilized form. In addition to more convenient handling of the enzyme, it provides for its facile separation from the product, thereby minimizing or eliminating protein contamination of the product. To date, pectinases have ...
