Interplay between desiccation and oxidative stress responses in iron-oxidizing acidophilic bacteria.

Variations in water availability represent a foremost stress factor affecting the growth and survival of microorganisms. Acidophilic bioleaching bacteria are industrially applied for releasing metals from mineral sulphides, and they are considered extremely tolerant to oxidative conditions prevailing in acidic bioleaching environments. Such processes usually are performed in heaps and thus these microorganisms are also exposed to intermittent desiccations or high osmolarity periods that reduce the water availability.

Parametric investigation of ultrashort pulsed laser surface texturing on aluminium alloy 7075 for hydrophobicity enhancement.

Unlabelled: Hydrophobicity plays a pivotal role in mitigating surface fouling, corrosion, and icing in critical marine and aerospace environments. By employing ultrafast laser texturing, the characteristic properties of a material's surface can be modified. This work investigates the potential of an advanced ultrafast laser texturing manufacturing process to enhance the hydrophobicity of aluminium alloy 7075.

Neurogastroenterology and Motility Disorders of the Gastrointestinal Tract in Cystic Fibrosis.

Purpose Of Review: To discuss all the various motility disorders impacting people with Cystic Fibrosis (PwCF) and provide diagnostic and management approaches from a group of pediatric and adult CF and motility experts and physiologists with experience in the management of this disease.

Recent Findings: Gastrointestinal (GI) symptoms coexist with pulmonary symptoms in PwCF regardless of age and sex. The GI manifestations include gastroesophageal reflux disease, esophageal dysmotility gastroparesis, small bowel dysmotility, small intestinal bacterial overgrowth syndrome, distal idiopathic obstruction syndrome, constipation, and pelvic floor disorders.

Variation, during Shelf Life, of Functional Properties of Biscuits Enriched with Fibers Extracted from Artichoke ( L.).

To boost revaluation of industrial by-products of artichoke, this research tries to determine the stability throughout storage of phenolic compounds and their antioxidant activity in biscuits enriched with fiber-rich powders extracted from b y-products of artichokes (FRPA). To determine the most stable extraction method, biscuits were formulated with FRPA extracted by two different environmentally friendly extraction solvents: water (W) and a solution of 1% CaCl∙5HO (CA) and compared with biscuits made with pea fiber (P) and control biscuits (B) without fiber added. Initially and during storage, the biscuits enriched with FRPA (W, CA) showed a higher content of bioavailable polyphenols and antioxidant activity compared to the control biscuits (B) and the reference fiber (P, pea fiber).

Tips and Tricks to Avoid Complications With Scapula Tip-Free Flap.

Purpose: Create a practical step-by-step guide to harvesting this flap, highlighting the critical points that can create problems during surgery and the postoperative period.

Methods: The tips and tricks to harvesting the scapula tip-free flap are described in different points, describing the patient preparation and skin incision, identification of the anterior border of the latissimus dorsi, dissection of the pedicle, bone osteotomy, flap inset, and closure.

Results: As the scapula tip-free flap provides skin, muscle, and bone tissue, it is a valid option for the reconstruction of the defects maxillary and mandibular region for facial reconstruction.
