Ligation of bilateral IJV causes interruption of major part of venous drainage from Dural venous sinuses that causes complications such as gross facial edema, increased intracranial pressure, brain compression, coma and even death increasing the morbidity and mortality post-operatively. This case report illustrates a case of normalcy noted in post-operative period in a patient after ligation of bilateral IJV in left lower alveolus cancer.

Several preoperative risk factors have been shown to predict poor prognosis after rAAA repair. Notably, a preoperative dependent functional status has previously been shown to be associated with poor outcomes after several vascular surgery procedures.

Thus, enzymatic catalysis can be harnessed for “on demand” pumping in nano- and microfluidic devices powered by an intrinsic energy source. The mechanisms controlling the pumping have not, however, been completely elucidated.

Solitary neurofibromas are rare occurrence in salivary gland region as well as mons pubis of females. We present two cases of teenage girls with swelling in parotid region and mons pubis. Fine needle aspiration cytology was inconclusive in both cases.

Here we show that surface-immobilized enzymes that are independent of adenosine triphosphate function as self-powered micropumps in the presence of their respective substrates. In the four cases studied (catalase, lipase, urease and glucose oxidase), the flow is driven by a gradient in fluid density generated by the enzymatic reaction.
