Columellar skin defects may be caused by excision of cutaneous malignancy, trauma, or tissue necrosis associated with surgery. Although columellar skin necrosis rarely occurs following rhinoplasty, this condition might be more common when using an external approach than a closed approach. Columellar skin incision performed with exaggerated tip augmentation may cause columellar necrosis. The nas...

Abstract Background Crassulacean acid metabolism (CAM) photosynthesis is an important carbon fixation pathway especially in arid environments because it leads to higher water-use efficiency compared C3 and C4 plants. However, the role of DNA methylation regulation CAM not fully understood. Results Here, we performed temporal methylome transcriptome analysis non-photosynthetic (white base) photo...

In this paper, the conformal mapping method was adopted to solve the problem of an infinite plate containing a central lip-shaped crack subjected to remote biaxial loading. A kind of leaf-shaped configuration was also constructed in order to solve the problem. The analytical result showed that the singularity order of the stress field at the tip of a lip-shaped crack remains −1/2, despite the d...

Although balloon angioplasty in heart and lower extremity vessels has been extensively studied and reported, little information exists regarding its use for digital ischemia in the hand. We report a case of successful balloon angioplasty of the distal radial artery to reverse present and prevent further digital tip cyanosis and necrosis.

This paper describes attempts to localize the site of perception of low temperatures (0-10 degrees C) during thermoinduction in Thlaspi arvense L. Reproductive development (stem elongation and flower formation) was observed when shoots were cooled to 4 degrees C for 4 weeks and then returned to 21 degrees C while maintaining the roots constant 21 degrees C. However, chilling the roots was ineff...

A 61-year-old female suffered from disseminated joint pain (both hands, elbows, knees, ankles) with a prominent Raynaud phenomenon in both hands for 4 months before admission due to nausea. Acute kidney failure of unknown origin was diagnosed and acral cyanosis of fingers II–IV of the left hand with beginning finger tip necrosis became Fig. 1. Left hand at admission.

Effects of de®ciencies in N, P, K, Ca, Mg, B and Fe on leaf development, visual symptoms and shoot±root dry weight ratio were studied in Spathiphyllum `Sensation' grown hydroponically. Leaf nutrient contents of treated plants were analyzed to con®rm suspected de®ciencies. Leaf number, leaf area and chlorophyll content were all signi®cantly reduced in the nitrogen-de®cient plants similar to plan...

We investigated the within- and between-leaf variability in carbon nitrogen isotope composition (?13C ?15N) total (TN) content two grapevine cultivars (Vitis vinifera cv. Chasselas Pinot noir) field-grown under rain-fed conditions. The within-leaf was studied discs sampled from base-to-tip left right regions margin to midrib. intra- interplant by comparing leaves at different positions along sh...

lemon balm (melissa officinalis l.) is an herbaceous perennial plant of the lamiaceae family that has a wide edible and medicinal uses. in this research the potential of five different explants (nodal segments, shoot tip, cotyledon, hypocotyl and leaf segments) on ms mediums supplemented with different concentrations of 6-benzylaminopurine (bap) (2.2, 4.4 and 8.8 µm) alone or in combination wit...
