AgsE-deficient strain

The present invention relates to a mutant microbial host cell which is deficient in the production of the AgsE protein or in the production of an homologous thereof if compared with a parent microbial host cell which has not been modified and measured under the same conditions. It has been surprisingly found that when the mutant microbial host cell according to the invention is used in a method to produce a compound of interest, for example an enzyme, an improved yield of said compound is obtained if compared to a method in which a parent host cell which has not been modified is used when measured under the same conditions.

Glucose Oxidase Compositions As A Neonate Anticonvulsant
20180185456 · 2018-07-05 ·

Neonatal seizure is different from adult seizure, and many antiepileptic drugs that are effective in adults often fail to treat neonatal seizure. Gluconic acid, a natural organic acid enriched in fruits and honey, and the glucose oxidase enzyme, is shown herein to potently inhibit neonatal epilepsy both in vitro and in vivo. Sodium gluconate is shown to inhibit epileptiform burst activity in cell cultures and protect neurons from kainic acid-induced cell death. Sodium gluconate also inhibited epileptiform burst activity in brain slices in a manner that was much more potent in neonatal animals than in older animals. Consistently, in vivo EEG recordings also revealed that sodium gluconate inhibited the epileptic seizure activity in a manner that was much more potent in neonates than in adult animals. Mechanistically, sodium gluconate inhibits voltage-dependent CLC-3 Cl.sup. channels both in neuronal cultures and in hippocampal slices. Together, these data suggest a novel antiepileptic drug gluconate that potently inhibits neonatal seizures through blocking CLC-3 Cl.sup. channels.

BIOSENSOR, TRANSPARENT CIRCUITRY AND CONTACT LENS INCLUDING SAME

Lenses, including contact lenses, and other transparent substrates include electronic circuits having patterned conductors and antenna structures which are transparent, flexible and conductive. A patterned conductor or antenna structure can be a combination of two-dimensional material such as graphene and one-dimensional material such as metal nanowires. The patterned conductor or antenna structure can be wrinkled or otherwise pre-stressed, to accommodate stretching and folding of the substrate. A biosensor having a sensor unit and an antenna unit, or other type of circuit, can be formed using these materials, and can be disposed on a contact lens.

GLUCOSE-RESPONSIVE INSULIN DELIVERY SYSTEM USING HYPOXIA-SENSITIVE NANOCOMPOSITES
20180110841 · 2018-04-26 ·

A closed-loop insulin delivery system is described. More particularly, the presently disclosed insulin delivery system can comprise glucose-responsive vesicles that release insulin in response to hypoxia triggered by enzymatic reduction of glucose. In addition or as an alternative to insulin, the delivery system can release other diabetes treatment agents, such as non-insulin-based diabetes treatment agents. The vesicles can be prepared from a hypoxia sensitive polymer, such as a hypoxia-sensitive hyaluronic acid (HS-HA). The HS-HA can comprise hydrophobic groups that can be reduced in hypoxic environments to form hydrophilic groups. The vesicles can be loaded into microneedles and microneedle array patches for use in the treatment of diabetes or to otherwise regulate blood glucose levels in subjects in need of such treatment.
