Effect of adding vasopressin on the distribution of lidocaine in tissues, anesthetic action, and circulatory dynamics.

We examined whether vasopressin affects the distribution, anesthesia duration, and circulatory dynamics of lidocaine. Blood flow was measured after injecting 0.003, 0.

Lung cancer associated with seronegative myasthenia gravis.

A 64-year-old man presented with diplopia, muscle weakness, a pulmonary nodule and mediastinal widening on a chest radiograph. He was diagnosed with clinical stage IIIA (T2aN2M0) lung cancer. His neurological symptoms worsened following the initiation of thoracic radiation therapy (60 Gy) and chemotherapy.

Effects of oral administration of Lactobacillus acidophilus L-92 on the symptoms and serum cytokines of atopic dermatitis in Japanese adults: a double-blind, randomized, clinical trial.

Objectives: Several studies on lactobacilli have demonstrated they are effective against atopic dermatitis (AD) in children, but there are very few reports of their effects in adults. We investigated the changes in AD symptoms in adults after the ingestion of the Lactobacillus acidophilus strain L-92 (L-92), which has been shown to have a curative effect on AD in children.

Methods: A double-blind, parallel-group, placebo-controlled comparison was performed on 49 AD patients aged ≥16 years using heat-killed L-92.

Synthesis of marine natural product (-)-pericosine E.

The first synthesis of (-)-pericosine E (6), a metabolite of the Periconia byssoides OUPS-N133 isolated originally from the sea hare Aplysia kurodai, has been achieved. Efficient and regioselective synthetic procedures for the synthesis of key intermediates, anti- and syn-epoxides 9 and 10, were developed using an anti-epoxidation of diene 12 with TFDO and a bromohydrination of 12 with NBS in CH(3)CN/H(2)O (2:3), respectively. In addition, comparison of the specific optical rotations between synthetic 6 and natural 6 elucidated that the naturally preferred enantiomer of pericosine E had the same absolute configuration as (-)-6 synthesized from chlorohydrin (-)-8 and anti-epoxide (+)-9.

Further stabilization of Leu¹⁵⁵ mutant thermolysins by mutation of an autodegradation site.

The autodegradation-resistant mutant thermolysins (TLNs), L155A (Leu(155) to Ala) and L155S (Leu(155) to Ser), were previously constructed by site-directed mutagenesis to enhance thermostability. These mutations suppressed autodegradation at position 154-155, resulting in increased thermostability. However, a new autodegradation site became apparent in these mutant TLNs, at position 155-156.
