Multidetector computed tomography imaging planning for bronchoscopy stent and valve placement in the treatment of COPD, air leaks, and airway stenosis.

Bronchoscopy using a flexible bronchoscope is considered a safe procedure and has been used for diagnosing and treating airway and parenchymal lung diseases. Bronchoscopic interventions in selected patients with emphysema, airway stenosis, and air leaks provide new treatment options. The application of multidetector computed tomography (MDCT) planning prior to bronchoscopy is comprehensively addressed.

Acceptability and applicability of an intervention programme with substance addicts.

The complexity of the problems related to the harmful use of substances requires regular questioning of practices. This article aims to explore the acceptability and applicability of an intervention programme for patients with problematic substance use. Qualitative study.

In vitro antiviral effect of ethanolic extracts from Azadirachta indica and Melia azedarach against goat lentivirus in colostrum and milk.

This study aimed to evaluate, in vitro, the use of leaf extracts of Azadirachta indica (A. indica) and Melia azedarach (M. azedarach) as antivirals against caprine lentivirus (CLV) in colostrum and milk of goat nannies.

Designing a Nurse-Led Program for Self-Management of Substance Addiction Consequences: A Modified e-Delphi Study.

Therapeutic interventions for people with problematic use of psychoactive substances can help tackle specific needs related to substance addiction consequences. This modified e-Delphi study aimed to establish consensus on a training program for self-management of substance addiction consequences. The study was conducted between February and April 2022, with an experts' sample of 28 participants in the first round and 24 in the second.

Phytol recycling: essential, yet not limiting for tomato fruit tocopherol accumulation under normal growing conditions.

Tocopherols are potent membrane-bound antioxidant molecules that are paramount for plant physiology and also important for human health. In the past years, chlorophyll catabolism was identified as the primary source of phytyl diphosphate for tocopherol synthesis by the action of two enzymes, PHYTOL KINASE (VTE5) and PHYTHYL PHOSPHATE KINASE (VTE6) that are able to recycle the chlorophyll-derived phytol. While VTE5 and VTE6 were proven essential for tocopherol metabolism in tomato fruits, it remains unknown whether they are rate-limiting steps in this pathway.

Surgical treatment analysis of idiopathic esophageal achalasia.

Background: Idiopathic esophageal achalasia is an inflammatory disease of unknown origin, characterized by aperistalsis of the esophageal body and failure of the lower esophageal sphincter in response to swallowing, with consequent dysphagia.

Aim: To demonstrate the results of surgical therapy in these patients, evaluating the occurred local and systemic complications.

Methods: Were studied retrospectively 32 patients, 22 of whom presented non-advanced stage of the disease (Stage I/II) and 10 with advanced disease (Stage III/IV).

Smear layer removal in canals shaped with reciprocating rotary systems.

The aim was to assess the presence of smear layer after canal instrumentation with two reciprocating rotary systems and a continuous motion one. Thirty canals were shaped with Reciproc, WaveOne or Mtwo systems. Smear layer was assessed following a three value scale at coronal, middle and apical levels with a scanning electron microscopy.

Last millennium environmental changes and climate inferences in the Southeastern Atlantic forest, Brazil.

This study presents paleoenvironmental data based on pollen, elemental and isotopic compositions of organic matter (TOC, N, δ(13)C and δ(15)N) and (14)C dating of 170 cm lake sediment record. Samplings have been made in Lagoa Grande at Parque Estadual Turístico do Alto Ribeira - PETAR, Southern São Paulo State, Southeastern Brazil. The variations in relative frequencies (in percentage) of arboreal pollen along the core range between 40 and 80%.
