Electrical stimulation of the lower eyelid orbicularis oculi muscle improves periocular dark circles.

Background: We developed and tested the safety and efficacy of a cosmetic device to improve dark circles using electrical muscle stimulation of the orbicularis oculi muscle.

Methods: Overall, 18 participants (36 eyes) were studied. The following five items were evaluated before and after the intervention:(1) the Clinical Dark Circle Score using clinical findings and photographs, (2) transcutaneous oxygen partial pressure (TcPO) on the lower eyelid, (3) thermography, (4) two-dimensional laser blood flowmetry, and (5) spectrophotometry.

Case of intraoperative acute pulmonary embolism diagnosed by transesophageal echocardiography under general anesthesia and successfully managed with extracorporeal membrane oxygenation.

Acute pulmonary thromboembolism (PTE), which carries a high mortality rate, is difficult to diagnose when it occurs intraoperatively. Therefore, patient prognosis depends on a prompt diagnosis by anesthesiologists. A 49-year-old woman underwent right lower extremity dissection due to a contusion of the right lower extremity caused by trauma.

Necrotizing fasciitis and septic shock due to streptococcal toxic shock syndrome in an elderly patient: A case report.

Streptococcal toxic shock syndrome (STSS) has a high mortality rate, and most patients die within a few days of onset. We report an elderly patient with STSS, necrotizing fasciitis and septic shock caused by group G streptococcus who was successfully treated with multidisciplinary therapy.

Eyelid Thread-lifting Treatment for Periocular Infantile Hemangioma in an Extremely Premature Low-birth-weight Infant.

Periocular infantile hemangioma (IH) sometimes hinders proper eye opening and limits the visual field. Even short-term deprivation of hemilateral vision may cause amblyopia in infants during the visually sensitive period and, thus, necessitates prompt treatment. Propranolol is a commonly known remedy for IH, though it may not act sufficiently to rapidly resolve a vision-threatening critical condition in an infant.

Sigma factor phosphorylation in the photosynthetic control of photosystem stoichiometry.

An imbalance in photosynthetic electron transfer is thought to be redressed by photosynthetic control of the rate of expression of genes encoding apoproteins of photosystem (PS)-I and PS-II in response to the redox state of plastoquinone (PQ), which is a connecting electron carrier. PS stoichiometry is then adjusted to enhance photosynthetic efficiency. In prokaryotes, sigma factors are well known for their participation in the control of RNA polymerase activity in transcription, whereas there have been no reports concerning their association with redox regulation.
