Effects of various substances on the binding of keratin monomers to S. maltophilia DHHJ cells for the induction of keratinase production.

Biodegradation effectiveness of S. maltophilia DHHJ is determined by its ability to attach to the hydrolyzed feather keratin monomers. This binding capacity can be influenced by many components in the culture medium.

A bilayer biocompatible polycaprolactone/zinc oxide/Capparis spinosa L. ethyl acetate extract/polylactic acid nanofibrous composite scaffold for novel wound dressing applications.

Capparis spinosa L. (CSL) is used in traditional medicinal purposes for wound dressing because it contains natural phenolic and flavonoid active compounds. In the current study, a bilayer of biocompatible and mechanically stable nanofiber scaffolds with polycaprolactone (PCL)/zinc oxide and Capparis spinosa L.

A novel pyroptosis-associated gene signature for immune status and prognosis of cutaneous melanoma.

Background: Cutaneous melanoma (CM) is a life-threatening destructive malignancy. Pyroptosis significantly correlates with programmed tumor cell death and its microenvironment through active host-tumor crosstalk. However, the prognostic value of pyroptosis-associated gene signatures in CM remains unclear.

[Free sensate intercostal artery perforator flap for hand soft tissue reconstruction].

Objective: To investigate the effectiveness of free sensate intercostal artery perforator flap for the hand soft tissue reconstruction.

Methods: Between March 2010 and September 2015, 19 cases of hand soft tissue defect were repaired with free sensate intercostal artery perforator flap, including 16 males and 3 females, aged from 18 to 53 years, with an average of 35.2 years.

Comparing surgical interventions for intertrochanteric hip fracture by blood loss and operation time: a network meta-analysis.

Background: Multiple operative treatments are available for the fixation of intertrochanteric femoral fractures. This analysis was conducted to provide guidance on the appropriate clinical choice to accommodate individual patients.

Methods: A systematic review was performed to identify relevant articles in databases.

[Repair of soft tissue defect in hand or foot with lobulated medial sural artery perforator flap].

Objective: To explore the clinical effect of the lobulated medial sural artery perforator flap in repairing soft tissue defect in hand or foot.

Methods: Since March 2012 to September 2014, 6 cases with soft tissue defects in hands or feet were treated by lobulated medial sural artery flaps pedicled with 1st musculo-cutaneous perforator and 2st musculo-cutaneous perforator of the medial sural artery. The size of the flaps ranged from 4.

Composition analysis and application of degradation products of whole feathers through a large scale of fermentation.

Purpose: Feathers are one of the most abundant bioresources. They are discarded as waste in most cases and could cause environmental pollution. On the other hand, keratin constituted by amino acids is the main component of feathers.

[Application of free posterior tibial artery perforator flap for skin defect on the dorsum of hand or foot].

Objective: To summarize the technique and therapeutic effect of free posterior tibial artery perforator (PTP) flap for skin defect on the dorsum of hand or foot.

Methods: The lower leg was divided into 6 sections equally from the level of tibial tuberosity to the connection of medial and lateral malleolus. The free PTP flap was designed along the inner edge of tibia within the proximal section 2 and 3.

Identification of a keratinase-producing bacterial strain and enzymatic study for its improvement on shrink resistance and tensile strength of wool- and polyester-blended fabric.

A wool-degrading bacterium was isolated from decomposition wool fabrics in China. The strain, named 3096-4, showed excellent capability of removing cuticle layer of wool fibers, as demonstrated by removing cuticle layer completely within 48 h. According to the phenotypic characteristics and 16S rRNA profile, the isolate was classified as Pseudomonas.

Characterization of a novel Stenotrophomonas isolate with high keratinase activity and purification of the enzyme.

A feather-degrading bacterium was isolated from poultry decomposition feathers in China. The strain, named L1, showed significant feather-degrading activity because it grew and reproduced quickly on basal medium containing 10 g/L of native feather as the source of energy, carbon, and nitrogen. According to the phenotypic characteristics and 16S rRNA profile, the isolate belongs to Stenotrophomonas maltophilia.

[Recapping laminoplasty for the treatment of severe burst fractures of thoracolumbar vertebra complicated with spinal stenosis].

Objective: To investigate operation skills, therapeutic effects and indications of racapping laminoplasty for the treatment of severe burst fractures of thoracolumbar vertebra complicated with spinal stenosis.

Methods: In the study, 41 patients with severe burst fractures of thoracolumbar vertebra complicated with spinal stenosis were treated with recapping laminoplasty. After the treatment, the size of vertebral canal, spinal stability, altitude recovery of vertebral body and rehabilitation of nerve function were observed.
