(1) ), nosological frontiers are still unclear and accordingly justify a comparative serological study of M.M., W.M., and B.M.G.
(2) However, the effects of such large-scale calvarial repositioning on subsequent brain mass growth trajectories and compensatory cranio-facial growth changes is unclear.
(3) Thus it is unclear how a language learner determines whether German even has a regular plural, and if so what form it takes.
(4) It is unclear if the changes in high-energy phosphates during endotoxin shock cause irreversibility.
(5) It’s unclear too whether Google will continue to pay Mozilla to be the default browser in countries outside the US, Russia and China when the current deal ends in December.
(6) Factors contributing to a more aggressive form of carcinoma are unclear and require further study.
(7) Two people were injured and taken to hospital, but it is still unclear who was responsible.
(8) The benefit of routine preoperative CT in patients with otherwise resectable colonic or rectal cancer remains unclear.
(9) Whether we are dealing with true Osborn waves is unclear.
(10) Many governments try to protect their tax base through national blacklists based on criteria that are often unclear and inconsistently applied.
(11) Although the mechanism(s) of Vb depolarization in OMCD is unclear at the moment, this depolarization suggests that OMCD is responsive to peritubular pH alterations.
(12) Poor prognostic factors included associated chondromalacia and an unclear preoperative diagnosis.
(13) Because the mechanism whereby Shigella dysenteriae I enterotoxin induces intestinal secretion is unclear, the effect of this toxin on adenylate cyclase activity in rabbit ileal mucosa was studied under various in vitro and in vivo conditions.
(14) The factors predisposing to and complicating acute renal failure (ARF) in the medical intensive care unit (ICU), and their relative influence on outcome during ARF are unclear.
(15) Preliminary studies using amino acid and ion inhibition studies suggested that transporter I was a system ASC-type carrier, transporter III a system L carrier, while the nature of transporter II was unclear.

(17) Hyperferritinemia, an unclear mechanism, is frequently observed in chronic alcoholics.
(18) Previously, we found resting metabolic rate increased at high altitude but the mechanism and consequences of this increase were unclear.
